The invention discloses a non-assembled guardrail and mainly relates to the field of children guardrails. The non-assembled guardrail comprises a frame and a protecting net mounted on the frame, at least one first hinging piece capable of being locked at the horizontal state is arranged on the upper side and the lower side of the frame, and second hinging pieces capable of being locked at the L-shaped state are arranged at two bottom ends of the frame. The non-assembled guardrail has the advantages that the guardrail can be folded into one bunch of rods, convenience in non-assembled hinging and firmness in unfolding limitation are realized, selling, using and storing are facilitated, safety of the guardrail can be guaranteed, and the non-assembled guardrail is widely applicable to use of fences and enclosures on beds.

The invention provides a concealed connecting structure of an assembled furniture member, which comprises furniture members and a connecting piece mounted on the furniture members, wherein the furniture members are provided with end openings; member through holes are formed in side walls of the furniture members; the connecting piece comprises a connecting inserting piece, gaskets and connecting shafts; the connecting inserting piece is provided with end block parts and inserting rod parts; at least two end block part side walls are obliquely or perpendicularly connected with the inserting rod parts; cross sections of the inserting rod parts are pi-shaped; pi-shaped concealed grooves are formed in the middle parts of the inserting rod parts; groove openings are formed in side walls of the inserting rod parts; the inserting rod parts are inserted into the end openings of the furniture members; the gaskets are arranged between the sides of the groove openings of the connecting inserting piece and the furniture members; cylindrical holes with screw threads in inner walls are formed in the centers of the gaskets; the connecting shafts are rod-shaped structures with screw threads in outer walls; axial grooves are formed in the centers of the top surfaces of the connecting shafts; and the connecting shafts penetrate through the member through holes of the furniture members to be connected with the cylindrical holes of the gaskets by screw threads, so that the gaskets compress the furniture members and the furniture members are fastened and connected with the connecting piece. The concealed connecting structure has the characteristics of being easy to assemble, and firm in connection without sway.

The invention relates to the technical field of textile machine equipment, in particular to a natural fiber drying packaging system. A drying box used for drying natural fibers is mounted on one side of the top of a base. Beating modules used for beating the natural fibers are arranged in the drying box. After being dried, the natural fibers are conveyed into a hollow pipe to be compressed. A steel frame is arranged above the hollow pipe. A sliding hole is formed in the middle of the steel frame. An impact sliding block is mounted in the sliding hole. The impact sliding block can slide up and down in the sliding hole but cannot rotate. An impact spring is mounted above the impact sliding block. Sawtooth-shaped steps are arranged on the lower surface of the impact sliding block. One end of a telescopic rotary shaft upwards penetrates the sliding hole and is connected with a compression motor. The other end of the telescopic rotary shaft is fixedly connected with a packing auger. The telescopic rotary shaft penetrates the impact sliding block and provided with an impact rod. The impact rod slides on the lower surface of the impact sliding block. According to the natural fiber drying packaging system, fast drying and compression on the natural fibers can be achieved, the processing procedure and processing time of the natural fibers can be shortened, and the use effect is good.

The invention relates to a prefabricated slab for prefabricated buildings, a connection method between the prefabricated slab and beams and a construction method, wherein the prefabricated slab includes a prefabricated slab body, and the prefabricated slab body has slab gluten and slab bottom ribs inside, defining the prefabricated slab The end face connecting the body and the beam is the joint surface. The multiple slab gluten and the multiple slab bottom ribs in the prefabricated slab body extend to the outside of the joint surface. The plate is fixedly connected with the plate ribs and the plate bottom ribs, and bolt lock holes are reserved on the connecting plate to solve the shortcomings of existing prefabricated panels such as difficult positioning of pins, difficulty in occlusion of adjacent prefabricated panels, and large amount of on-site welding; The invention also provides the connection mode and construction method of the prefabricated board and the beam.
