High-adaptability backrest lock capable of being assembled positively and negatively

Abstract

The invention relates to a high-adaptability backrest lock capable of being assembled positively and negatively. The high-adaptability backrest lock comprises a cover plate and a bottom plate, whereinthe cover plate and the bottom plate are buckled with each other to form a lock cavity; a large lock hook, a large lock hook rivet and a large lock hook return torsion spring are arranged in the lockcavity; the large latch hook is relatively and fixedly provided with a latch hook opening rivet; the lock hook opening rivet is linked with an opening arm; the opening arm is linked with an opening arm torsion spring; the high-adaptability backrest lock is characterized in that the cover plate is linked with a bracket assembly; a detachable connecting mechanism is arranged between the cover plateand the support assembly. The support assembly comprises a support, the support is provided with a cover plate mounting panel, a seat mounting panel and a supporting panel, and the cover plate is provided with a forward and reverse mountable mechanism. The high-adaptability backrest lock has the beneficial effects that the high-adaptability backrest lock capable of being assembled positively andnegatively is provided, the structure is improved, machining is convenient, the mold is simplified, the material utilization rate is increased, and high adaptability is achieved.

Description

Technical field [0001] The invention relates to the technical field of backrest locks, in particular to a backrest lock that can be installed in front and back with high adaptability. Background technique [0002] The car seat is a safety part. As a part of the seat, the seat lock has a very high requirement on the lock. The function of the general car seat lock is realized as follows: the lock hook of the seat lock and the lock ring on the body Engaged to achieve the locking function. [0003] The invention with the publication number "CN207225162U" announced a two-speed car seat lock, which includes a cover plate and a bottom plate. The cover plate and the bottom plate are interlocked to form a lock cavity. The lock cavity is equipped with a large lock hook and a large lock. The hook can rotate radially relative to the big lock hook rivet. The end of the big lock hook rivet close to the cover is provided with a big lock hook return torsion spring, and the side of the big lock ho...

Problems solved by technology

[0004] However, in the actual production process, the cover plate and the bottom plate have structural defects, and the cover plate and the bottom plate need more processing procedures such as flanging and bending, which directly leads to a more complicated production mold structure, and the edge of the cover plate and the bottom plate The various support structures designed, because their profiles are parallel to the plane of the cover plate and the bottom plate, it is difficult to process the general mold, so it is necessary to open another mold to process the cover plate and the bottom plate again, the production cost is high, and the processing cycle is long. , and the processing accuracy is reduced, and when the seat lock provided by the above technical solution is installed with the seat, it cannot be installed front and back, and can only be installed according to a specific installation direction
