The invention relates to an anti-tripping reverse buckling device. An oil pipe coupling is connected with an upper joint. An inner shoulder of a reverse buckling inner joint is hung on an outer shoulder of the upper joint. A reserve buckling external thread at the lower part of the reverse buckling inner joint is connected with a reverse buckling internal thread of the reverse buckling outer joint. The upper part of a lock sleeve is sleeved outside the upper joint. The upper joint is provided with a convex key. The interior of the lock sleeve is provided with a lock key groove, and the convex key is inserted in the lock key groove. The lock sleeve is fixed on the upper joint by a shearing pin. The interior of the reverse buckling inner joint is provided with a positive key groove, and the convex key is inserted in the positive key groove. A spring is arranged between the lock sleeve and the reverse buckling inner joint. The lower part of the lock sleeve is provided with a groove key, the upper part of the reverse buckling inner joint is provided with a groove key, and the groove keys are buckled. Under the action of the convex key, the lock key groove, the groove key on the lower part of the key sleeve and the groove key on the upper part of the reverse buckling inner joint, when the oil pipe is positively reversed, the connecting part of the reserve buckling external thread at the lower part of the reverse buckling inner joint and the reverse buckling internal thread of the reverse buckling outer joint can not trip, therefore, the invention can be matched with a tool for positively rotating oil pipes.

The invention relates to the technical field of cable wells, and discloses a cable well cover, which includes a cover body and a plurality of baffles. It is connected with the side wall of the vent so that the vent is divided into multiple sub-vents, so that the cable well cover has no parts protruding from the ground, which can play a role in ventilation and heat dissipation, and at the same time will not trip pedestrians or make vehicles It is bumpy, which is conducive to traffic, and there are several baffles in the vent to prevent pedestrians from falling, and the safety is high.

The invention provides a safety trampoline, which comprises jumping cloth and a frame, wherein the frame comprises a first bottom frame, a second bottom frame and a plurality of vertical pillars; thefirst bottom frame is fixedly connected to the upper ends of the vertical pillars; the second bottom frame is fixedly connected to the vertical pillars and is arranged under the first bottom frame; the outer contour of the second bottom frame is less than the outer contour of the first bottom frame and the second bottom frame is coaxial with the center of a first top frame; the jumping cloth covers the first bottom frame, and the jumping cloth is provided with a plurality of extension parts; the extension parts extend towards the second bottom frame, and the extension parts are arranged at intervals; the vertical pillars are inserted in gaps of the extension parts; tension springs are arranged around the outer side of the second bottom frame; the tension springs are arranged between the first bottom frame and the second bottom frame in an inclined mode; and one end of each tension spring is fixedly connected to the first bottom frame and the other end is fixedly connected to the corresponding extension part. According to the safety trampoline provided by the invention, users, who take exercises on the trampoline, cannot get stumbled by the springs, so that the safety performance ofthe trampoline is enhanced; and under the circumstance of a same area, the effective using area of the trampoline is increased.

The invention discloses a novel inflatable bathroom water retaining bar, and belongs to the technical field of construction engineering. Commonly, a bathroom needs to achieve wet-dry separation to ensure that goods are not eroded by water. Wet-dry separation can be achieved by additionally arranging a water retaining bar at the edge of a shower room. The novel inflatable bathroom water retaining bar is technically characterized in that an inflatable air bag can adjust the height of the water retaining bar through the inflating volume, a water level inductor is mounted on the air bag, the gas inflating volume can be increased or decreased according to the height of the water level, and the height of the water retaining bar can be adjusted through the inflating volume. The embedding depth ofa dovetail groove into the ground is equal to the height of the dovetail groove, so that flatness of the ground can be ensured when the air bag is not inflated. The novel inflatable bathroom water retaining bar has the following advantages that wet-dry separation of the bathroom is ensured, it is ensured that the goods cannot be eroded, the safety is improved by utilizing a pressure inductor, thewater retaining bar is fixed in a mode of gluing or embedment and can be replaced conveniently, the height of the water retaining bar is not fixed, the height of the dovetail groove can be adjusted through the inflating volume according to the water quantity, the dovetail groove is pre-buried underground, and therefore both attractiveness and convenience are achieved.

The invention relates to an LED illuminating lamp mounting bracket. The LED illuminating lamp mounting bracket comprises a pre-embedded frame, two orientation adjusting supports and two fixing devices, wherein the two orientation adjusting supports are mounted in the pre-embedded frame and are symmetrically arranged, and the fixing devices are mounted at the upper ends of the orientation adjustingsupports. According to the LED illuminating lamp mounting bracket, the problems that when mounted on existing brackets, landscape spotlights have small illuminating range and large height and angle and are fixed by connecting pieces mostly, orientation adjustment is inconvenient, work of the landscape spotlights is finished after daybreak and pedestrians are probably tripped by the landscape spotlights and injured carelessly during walking and the like can be solved, and the LED illuminating lamp mounting bracket has the advantages as follows: the two landscape spotlights are mounted and fixed simultaneously, the illuminating range is increased, the orientations of the landscape spotlights are rapidly adjusted according to the current environment, and the adjustment is convenient; the bracket is embedded, all that is required is to embed the landscape spotlights into the pre-embedded frame after daybreak, people cannot be tripped and are prevented from being injured and the like.

The invention discloses an electric heating film and a heating structure. The electrothermal film includes a heating layer, at least one side of the heating layer is closely attached to a fireproof insulation layer, and a shielding layer is stacked on the fireproofing insulation layer, and the shielding layer is electrically connected to the neutral terminal of the heating layer. connection, the heating layer is also provided with live wire terminals. Even if the electrothermal film provided by the embodiment of the present invention is damaged by puncture or the like during construction, it can still be used normally; due to the existence of the fireproof insulation layer, it can ensure that the local structure damaged by perforation will not be further expanded due to burning or ignition. Therefore, the risk of current leakage can be greatly reduced, and the leakage protection device of the entire circuit will not be tripped; at the same time, the electric heating film provided by the embodiment of the present invention has a relatively large contact resistance due to the carbon-based heating layer, so there is almost no risk of contact electric shock, and it is safe to use high sex.
