Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram of the utility model lock hook.
Fig. 3 is birds-eye view of the present utility model.
The specific embodiment
Accompanying drawing has represented structure of the present utility model, further illustrates by reference to the accompanying drawings its details below again.This automobile chair backrest lock, include permanent seat 1 and lock hook 2, described permanent seat 1 is provided with groove, described lock hook 2 bottoms are placed in groove, described lock hook 2 bottoms are connected with permanent seat 1 by bearing pin 3, bearing pin 3 one end connect back-up ring 4, between described lock hook 2 and permanent seat 1, are provided with pull back spring 5, and the two ends crotch rotation reinforcing of described pull back spring 5 is tied with permanent seat 1 and lock hook 2 hooks respectively; Described permanent seat 1 is by single sheet metal component punch forming, and is respectively equipped with projection welding point on four angles of its attachment face; Described lock hook 2 adopts metal high-strength plate to do inserts, with nylon injection-molding moulding.
In the utility model, permanent seat 1, by sheet metal component punch forming, guarantees dimension precision requirement, and intensity is good, indeformable, and attachment face has four projection welding points, is convenient to user's welding manufacturing line and uses; Lock hook 2 adopts metal high-strength plates to do inserts, and with nylon injection-molding moulding, i.e. the surperficial injection moulding of lock hook 2, makes that intensity significantly improves, good damping effect, friction noise; Pull back spring 5 windings are connected with lock hook 2 with permanent seat 1 on bearing pin 3 leading portions, and the crotch pretension angle of pull back spring 5 strengthens, and torsion strengthens avoids bearing pin 3 and lock hook 2 to throw off, and is connected reliably with permanent seat 1 with lock hook 2; Bearing pin 3 is connected with lock hook 2 square hole positions, bottom with the square key position that the connection mode of lock hook 2 is bearing pin 3 middle parts; 4 pairs of bearing pins 3 of back-up ring play fixation.In use, lock hook 2 can rotate by bearing pin 3 the utility model on permanent seat 1, then by pull back spring 5, is resetted.The utility model is rational in infrastructure, and easy to use being suitable for leaned on occasion after various back seats.The personnel that ride have been improved to safety and traveling comfort, realized the protective effect to human body backrest.
