Detailed Description

In order to explain technical contents, structural features, and effects achieved by the present invention in detail, the following detailed description is given with reference to the embodiments and the accompanying drawings.

As shown in fig. 1 to 3, the vehicle window screening lock 100 of the present invention includes a seat body 1, an outer handle 2, an inner handle 3, a driving member 4, a locking member 5, and an elastic member 6, wherein the elastic member 6 is a compression spring. The outer handle 2 and the inner handle 3 are pivoted to the inner side and the outer side of the seat body 1 through a rotating shaft 7 and are coaxially fixed with each other, and the driving piece 4 is fixed on the rotating shaft 7; the locking piece 5 is slidably disposed on the seat body 1, one end of the locking piece 5 is provided with a latch 51, and the other end extends out of a fitting piece 52, and the fitting piece 52 is slidably abutted against the driving piece 4; when the driving element 4 rotates, the engaging element 52 can be pushed to move, so as to drive the latch 51 to retract into the seat body 1. The elastic member 6 is disposed between the seat body 1 and the locking member 5 to provide an elastic force for extending the locking member 5 out of the seat body 1. The locking piece 5 can automatically extend out of the seat body 1 by utilizing the elasticity of the elastic piece 6, thereby achieving the purpose of automatic locking.

As shown in fig. 2 to 5, a sliding groove 11 is formed in the seat body 1, and the latch 51 is slidably disposed in the sliding groove 11. By arranging the lock tongue 51 in the sliding groove 11, the lock tongue 51 can be guided, the lock tongue 51 can be ensured to stably and smoothly move, and foreign objects are prevented from entering the movement affecting the lock tongue 51. The latch 51 is provided with a receiving groove 511, and the elastic element 6 is received in the receiving groove 511. The receiving groove 511 may not only position the elastic member 6, but also protect the elastic member 6, so that the elastic member 6 may work more stably. Specifically, a positioning column 512 is disposed in the accommodating groove 511, and the elastic member 6 is sleeved on the positioning column 512. The positioning post 512 can further position the elastic member 6, so as to prevent the elastic member 6 from shifting, thereby improving stability.

Referring to fig. 3 to 5, an abutting inclined surface 53 is disposed on one side of the engaging member 52 abutting against the driving member 4, and an end of the driving member 4 slidably abuts against the abutting inclined surface 53. Through set up conflict inclined plane 53 in fitting piece 52 one side, conflict inclined plane 53 can make with the torsion that driving piece 4 exported converts thrust, thereby makes fitting piece 52 slide, reaches the drive the mesh that tongue 51 stretches out and draws back with sliding.

As shown in fig. 2, the seat body 1 includes an upper seat 1a and a lower seat 1b, a movable space 1c is formed between the upper seat 1a and the lower seat 1b, and the driving member 4 and the mating member 52 are flat structures and are disposed in the movable space 1 c.

Referring to fig. 3, a limit protrusion 513 is disposed on one side of the latch 51, and a limit portion 12 capable of abutting against the limit protrusion 513 is disposed on the seat body 1. Through the cooperation of the limiting projection 513 and the limiting part 12, the bolt 51 can be prevented from excessively extending, and the sliding accuracy and the working stability of the bolt 51 are ensured.

In combination with fig. 3 and 6, when unlocking, only one of the outer handle 2 and the inner handle 3 needs to be rotated to rotate the rotating shaft 7. The rotation shaft 7 rotates to drive the driving member 4 to rotate, and the front end of the driving member 4 slidably abuts against the abutting inclined surface 53 of the locking member 5 when rotating, so as to push the engaging member 52 to translate. The engaging piece 52 can bring the latch 51 to slide in the sliding groove 11, and compress the elastic member 6. At this time, the latch 51 can be retracted into the seat body 1, i.e., unlocked. When the lock is needed, only the handle needs to be released, under the action of the elastic restoring force of the elastic piece 6, the lock tongue 51 can extend out of the sliding groove 11 again, when the lock tongue 51 is encountered, the lock tongue 51 drives the matching piece 52 to translate, the matching piece 52 pushes the driving piece 4 to rotate, the side of the driving piece 4 can drive the rotating shaft 7 to reset, and the lock can be locked again at the moment.

Compared with the prior art, in the invention, the driving element 4 is fixed on the rotating shaft 7, the locking element 5 is arranged on the seat body 1 in a sliding manner, the matching element 52 is arranged on the locking element 5, and the matching element 52 is matched with the driving element 4 in a sliding manner, so that the driving element 4 can push the matching element 52 to move when rotating, and the bolt 51 of the driving element 4 can be driven to act, thereby achieving the purpose of locking or unlocking. The whole structure is very simple and compact, the connection is stable and reliable, the cost is very low, and the wide application is facilitated.

The above disclosure is only a preferred embodiment of the present invention, and certainly should not be taken as limiting the scope of the present invention, which is therefore intended to cover all equivalent changes and modifications within the scope of the present invention.
