The car door lock is a complex and precise component, and its structure mainly consists of the following key parts: 1. Large support body: As the installation foundation of the large lock tongue, the large support body plays a vital role. Its head is tightly riveted to the large lock tongue, and the rectangular hole in the middle matches the hanging ear on the pull tab to ensure the smooth movement of the large lock tongue. In addition, there are steps on the outside of the large support body for clamping the brake pads, and the lower part is closely matched with the slider clamp. This not only facilitates the pulling of the slider, but also ensures that the large support body does not retract when pushed. will be hindered. 2. Small support body: The small support body is mainly responsible for installing the small lock tongue and controlling the self-locking function of the large lock tongue. Its head is equipped with a small lock tongue, and the protruding triangular part in the middle is used to push the brake pads to release the self-locking effect of the brake pads on the large support body. 3. Pull tab: The pull tab plays a key role in positioning and unlocking self-locking in car door locks. The hanging ears on the top can be inserted into the rectangular hole in the middle of the large support body to realize the retraction in conjunction with the large support body. At the same time, the supporting angles on both sides of the pull tab can move the brake pads to further release their self-locking on the large support body. The small round hole in the middle of the pull tab is used for precise positioning, while the protrusions on both sides ensure that the large support body can move smoothly in the groove formed. Finally, the bayonet on the lower part of the pull tab fits closely with the slider clamp to ensure precise movement under the control of the slider.
