The existing lock is composed of a lock ring and a lock seat. The lock ring and the lock seat are two separate parts. After the two parts are processed, they are fixedly connected by riveting. The existing structure is as follows Figure 1 , Figure 2 After the lock buckle is fixed to the lock ring and the lock seat, the lock buckle needs to be cleaned. There will be cleaning liquid residue in the gap where the lock buckle and the lock seat are riveted. The cleaning liquid remaining in the riveted gap between the lock buckle and the lock seat is prone to rust-like residual marks after a period of time. Therefore, it is necessary to improve the existing problems. Summary of the invention

[0003] The purpose of the utility model is to solve the problems raised in the above background technology and provide a lock structure for automobile doors.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a lock structure for a car door, including a lock ring and a lock seat, the lock ring and the lock seat are an integrated fixed structure, the two roots connecting the lock ring and the lock seat are respectively provided with a flared reinforcement part, and the flared reinforcement part, the lock ring and the lock seat are an integrated structure.

[0005] In the above-mentioned lock catch structure for automobile doors, the lock ring, the lock seat and the expanded reinforcement portion at the connection between the two are made by integral casting.

[0006] In the above-mentioned latch structure for automobile doors, the flared reinforcement portion is designed as a two-section structure, including an upper flared portion and a lower flared portion.

[0007] In the above-mentioned latch structure for automobile doors, an intermediate reinforcement portion is provided between the two flared reinforcement portions.

[0008] In the above-mentioned latch structure for automobile doors, the middle of the middle reinforcement portion is concave, and both ends are gradually inclined upward to connect with the expanded reinforcement portion.

[0009] In the above-mentioned latch structure for automobile doors, the middle reinforcement portion is in a straight horizontal shape and connected with the expanded reinforcement portions at both ends.

[0010] In the above-mentioned latch structure for automobile doors, a groove is provided at the bottom of the lock seat corresponding to the middle reinforcement portion.

[0011] The utility model has the following beneficial effects:

[0012] The lock ring and the lock seat of the lock buckle in the utility model adopt an integrated structural design. Compared with the existing split structure, not only the structural strength is further improved, but also there will be no connection gap between the lock buckle and the lock seat. In this way, when the lock buckle is cleaned after processing, there will be no residual traces of rust caused by the cleaning liquid, thereby avoiding the defects of the existing structural design.
