The two sealing rings 303 can increase the buffering capacity between the two mounting nut holes 301 and the car door, reducing abnormal noise.

[0039] The working principle of the automotive latch nut plate provided by this utility model is as follows:

[0040] In use, the locking limit plate 5 and the locking buckle 6 are installed inside the limiting groove 401 and the insertion groove 402. Then, the two pre-locking sliders 404 are controlled to move closer to each other along the corresponding pre-locking grooves 403 until the two clamping blocks 405 clamp the locking limit plate 5, thereby locking the locking buckle 6. The positioning nut hole 201 is inserted into the pre-drilled positioning hole on the car door, and the positioning block 202 is used for positioning. At the same time, the two mounting nut holes 301 are set in the pre-drilled mounting holes on the car door. With the positioning nut hole 201 as the origin, the position of the two mounting nut holes 301 on the nut plate 1 is swung to adjust the angle of the locking buckle 6. After completion, the positioning bolts are threaded to the positioning nut holes 201 and the positioning holes to complete the initial fixation. The two mounting bolts are threaded to the two mounting nut holes 301 and the two mounting holes to complete the final fixation.
