[0008] The insertion end of the elastic arm mounting hole is provided with a stopper structure, the C-shaped elastic arm fits in the elastic arm mounting hole and the cover plate stops at the stopper structure. The stopper structure is not only conducive to the stability of the cover plate and the entire elastic locking part, but also, the cover plate is embedded in the stopper structure, and the surface of the plug is flat and beautiful.

[0009] The bottom of the C-shaped elastic arm is provided with a bottom surface fixing hook, and the bottom of the elastic arm mounting hole groove is provided with a plug bottom side limiting step, and the bottom surface fixing hook cooperates with the plug bottom side limiting step. The elastic locking fastener formed by the cover plate and the C-shaped elastic arm is inserted into the elastic arm mounting hole groove, the cover plate cooperates with the stop structure, and the side wall fixing hook cooperates with the limiting hole groove, and the bottom surface fixing hook cooperates with the plug bottom side limiting step, so as to realize the assembly of the elastic locking fastener and the plug, which is conducive to improving the stability of the elastic locking fastener and the plug.

[0010] The side of the C-shaped elastic arm is provided with a limiting rib, and the side wall of the elastic arm mounting hole groove is provided with a side wall limiting step, and the limiting rib cooperates with the side wall limiting step. The elastic locking fastener formed by the cover plate and the C-shaped elastic arm is inserted into the elastic arm mounting hole groove, and the limiting rib and the side wall limiting step are aligned and limited, and the cover plate is further matched with the stop structure, the side wall fixing hook cooperates with the limiting hole groove, and the bottom surface fixing hook cooperates with the limiting step on the bottom side of the plug, so as to realize the assembly of the elastic locking fastener and the plug. Among them, the limiting rib cooperates with the side wall limiting step to limit the elastic deformation amplitude of the C-shaped elastic arm.

[0011] The handle key is located at one end of the C-shaped elastic arm, and a reset C-shaped elastic rib is provided at the other end of the elastic arm, and the handle key is located above the reset C-shaped elastic rib. When unlocking, press the handle key downward, and the handle key is pressed down to the reset C-shaped elastic rib to be limited. While the reset C-shaped elastic rib accumulates elastic potential energy, the C-shaped elastic arm is deformed by force, and the lock rib is displaced, and the lock rib and the socket hook are unlocked. Release the handle key, the elastic potential energy of the C-shaped elastic arm and the reset C-shaped elastic rib is released, and the C-shaped elastic arm is reset. The setting of the reset C-shaped elastic rib is not only conducive to the reset of the C-shaped elastic arm, but also has an enhanced effect on the locking of the lock rib on the socket hook, preventing the lock rib from detaching from the socket hook, which is conducive to improving the safety of the elastic lock.

[0012] The C-shaped integrated elastic lock structure of the utility model combines the handle, spring and cover in the prior art into an integrated structure, which effectively reduces the production cost of parts and improves product assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
