The telescopic road safety guardrail comprises two stand columns, wherein the two stand columns are parallel, one side surfaces of the two stand columns are oppositely arranged, a plurality of protective rod assemblies movably connected in sequence are installed between the two stand columns, containing grooves for containing the multiple protective rod assemblies are formed in the opposite side surfaces of the two stand columns in a sunken mode, locking pieces for locking the two stand columns are installed on the stand columns, and inclined struts are arranged on the two sides of the stand columns. The plurality of sets of protective rod assemblies are stored in the stand columns, the overall size of the safety guardrail is reduced, the space, which is occupied by the protectiverod assemblies, outside the safety guardrail is reduced, and the safety guardrail is convenient to carry.

The invention relates to the technical field of connectors, and provides a detachable connector which comprises a first cylinder body, a second cylinder body, a third cylinder body, a fourth cylinderbody, a first conductive terminal and a second conductive terminal, wherein one end of the second cylinder body is inserted into the first cylinder body; the third cylinder body sleeves and is fixed at the other end of the second cylinder body; the fourth cylinder body sleeves the outer side of the third cylinder body and can slide relative to the third cylinder body; the first conductive terminalis arranged in the first cylinder body; and the second conductive terminal is arranged in the second cylinder body and is connected with the first conductive terminal in an inserting manner. A firsthook body is arranged on the third cylinder body, and a concave part hooked by the first hook body is arranged on the outer surface of the first cylinder body; a second hook body is arranged on the fourth cylinder body; and when the fourth cylinder body slides relative to the third cylinder body, the second hook body hooks the first hook body and pulls the first hook body out of the concave part;and when the fourth cylinder body slides, the second hook body on the fourth cylinder body hooks the first hook body and then pulls the hook body out of the concave part, so that the first hook body is unhooked from the concave part.

The present invention provides a display substrate and a preparation method thereof. The display substrate includes a base, a plurality of binding electrodes and a plurality of functional elements, the binding electrodes are arranged on the base, the adjacent binding electrodes are spaced apart from each other, the functional elements are located on the side of the binding electrodes away from the base, and the binding electrodes are connected to The electrodes of the functional element are bound and connected, and a blocking structure is also arranged on the substrate, and the blocking structure is distributed at least in a part of the space area between the adjacent binding electrodes. The display substrate, by setting the blocking structure, can block the flow of the molten electrode material between the adjacent binding electrodes during eutectic bonding, so as to avoid the liquefaction flow of the electrode material and the adjacent binding electrodes. There is a problem of short circuit between the electrodes of the functional elements and between the electrodes of the functional elements; the blocking structure can clamp and fix the binding electrodes, thereby ensuring the firmness of the binding connection; there is also a certain warpage in the carrier plate carrying the functional elements. case to achieve good electrode binding.

The invention belongs to the technical field of construction equipment, and particularly relates to a drill stem dismounting and mounting device of a pile driver. By adopting the drill stem dismounting and mounting device, the problems that current drill stems of the pile driver are not convenient to dismount and mount and the like are solved. The drill stem dismounting and mounting device comprises a rack, wherein a grouting plate which is connected with a power head is movably arranged on the rack; a plurality of grouting plate connectors are arranged on the grouting plate in a penetration manner; the grouting plate connectors are separately connected with the grouting plate through a peripheral rotary connection structure; a plurality of drilling stem bodies which are in one-to-one correspondence with the grouting plate connectors are arranged below the grouting plate connectors; the drill stem bodies are connected with the grouting plate connectors through threaded connection structures; and peripheral positioning structures which can peripherally position the drill stem bodies and the grouting plate connectors are arranged between the drill stem bodies and the grouting plate connectors. The drill stem dismounting and mounting device has the advantages that the structure is simple and reasonable; the connection parts of the drill stems and a grouting mechanism are convenient to dismount and mount; the stability is good; the connection strength of the drill stems is high; the drill stems are not separated from the grouting plate easily during peripheral rotation; and peripheral positioning of the drill stems and the grouting plate connectors are realized through pressure plate drivers.

A fan assembly includes a first fan including a first frame, a second fan including a second frame, the first frame of the first fan has a first jointing surface, and the second frame of the second fan has a second jointing surface. A first concave structure and a first flange are formed along two ends of a first direction of the first jointing surface of the first fan, and a first concave structure and a first flange are formed along two ends of a first direction of the second jointing surface of the second fan respectively. The first flange of the first fan moves relatively to the second jointing surface of the second fan, and is embedded in the first concave structure of the second fan.

The invention discloses a tile-shaped grass planting brick. The tile-shaped grass planting brick is technically characterized by comprising a brick body, wherein the brick body is arc-shaped; wing edges are arranged on the two sides of the brick body along the length direction; the wing edge on one side is provided with a concave part along the length direction of the brick body, and the wing edge on the other side is provided with a bulge matched with the concave part; each of the two wing edges is provided with an extending part pointing to the inner wall of the brick body; the end face of each extending part is arc-shaped; and the curvature of each end face is the same as that of the inner wall of the brick body. The tile-shaped grass planting brick has the advantages of high antiquing performance, excellent biological performance, good stability, high structural strength and the like.

The invention discloses a wallboard prefabricating mold, relates to a mold, and solves the problem of troublesome installation of a common mold. The wallboard prefabricating mold comprises a base, andtemplates placed on the base; a connecting mechanism is arranged between two adjacent templates; the connecting mechanism comprises at least two insertion ports formed in one template, matching grooves formed in the template, engaging grooves formed in the inner walls of the matching grooves, insertion blocks fixed on the other template, and engaging bars integrally arranged on the insertion blocks; the section sizes of the matching grooves are equal to the section sizes of the insertion blocks; when the insertion blocks are embedded in the matching grooves, the engaging bars are engaged withthe engaging grooves; and stop mechanisms for limiting disconnection of the insertion blocks from the matching grooves are arranged in the insertion ports. The wallboard prefabricating mold has the following advantages and effects: compared with a general bolt fixing mode, the insertion assembly mode can simplify the template mounting steps and shorten the mounting period to achieve the purpose of improving the prefabricated part production efficiency.

The invention relates to a shoe and provides a puzzle shoe capable of promoting mentality. The puzzle shoe can satisfy the wearing requirement in daily life and meanwhile adds child interest to children. The puzzle shoe comprises an outer sole and a vamp arranged on the outer sole. A connecting surface used for being connected with the outer sole is arranged at the bottom of the vamp, and a shoe cavity used for containing a foot is defined by the vamp and the connecting surface.
