[0023] Example

[0024] like Figures 1 to 3As shown, the anti-theft car door lock structure proposed in this utility model includes a connecting plate 1 and an anti-theft cover plate 2 covering the connecting plate 1. The outer surface of the anti-theft cover plate 2 away from the connecting plate 1 is provided with a U-shaped lock 21. The ends of the U-shaped lock 21 near the anti-theft cover plate 2 are fixedly connected with reinforcing blocks 26. The reinforcing blocks 26 increase the structural strength and durability between the anti-theft cover plate 2 and the U-shaped lock 21. The end of the reinforcing base block 26 furthest from the U-shaped latch 21 is fixedly connected to the anti-theft cover plate 2. A pair of screw mounting holes 13 are provided on the connecting plate 1. Each screw mounting hole 13 contains a first screw 14 and a second screw 16, which are identical in size, to fix the connecting plate 1 to the car door. This anti-theft mechanism, which obscures the screw mounting holes 13 on the connecting plate 1 and the anti-theft cover plate 2, confuses thieves. The complex design of this anti-theft mechanism can easily cause thieves to experience anxiety, hesitation, or even abandon their theft attempt due to excessive pressure when faced with unfamiliar or misleading security mechanisms. Psychological pressure can also affect a thief's judgment and speed of action, thus improving the anti-theft effect.

[0025] Furthermore, the anti-theft mechanism includes a rotating support block 11 fixedly connected to the connecting plate 1. A locking block 12 is fixedly connected to the end of the rotating support block 11 away from the connecting plate 1. A rotation adjustment hole 22 is provided in the middle of the anti-theft cover plate 2, which is movably fitted with the rotating support block 11. There is significant friction between the rotating support block 11 and the rotation adjustment hole 22, which prevents thieves from manually rotating the anti-theft cover plate 2, thus misleading them into believing that the connecting plate 1 and the anti-theft cover plate 2 are fixedly connected. The connecting plate 1 has a pair of screw connection slots 15, and the anti-theft cover plate 2 has a pair of fastening screws 23 that are screwed into the corresponding screw connection slots 15.

[0026] The anti-theft mechanism also includes a pair of first hexagonal decorative slots 24 and second hexagonal decorative slots 25 formed on the anti-theft cover 2. These slots serve to allow the first screw 14 and second screw 16 to pass through and tighten / untighten. They also serve a decorative purpose, intended to mislead thieves. The first hexagonal decorative slots 24 and second hexagonal decorative slots 25 are the same size. The pair of first hexagonal decorative slots 24 and second hexagonal decorative slots 25 are symmetrically arranged around the central axis of the U-shaped latch 21. The first hexagonal decorative slot 24 corresponds to the first screw 14, and the second hexagonal decorative slot 25 corresponds to the second screw 16.

[0027] Furthermore, the distance from the first hexagonal decorative groove 24 to the rotation adjustment hole 22 is greater than the distance from the second hexagonal decorative groove 25 to the rotation adjustment hole 22, the spacing between the first hexagonal decorative grooves 24 is greater than the spacing between the second hexagonal decorative grooves 25, and the distance from the first screw 14 and the second screw 16 to the rotation support block 11 corresponds to the first hexagonal decorative groove 24 and the second hexagonal decorative groove 25.

[0028] In this embodiment, when an anti-theft car door lock latch structure is required, such as Figure 1 As shown, first, rotating the U-shaped latch 21 causes the anti-theft cover 2 to rotate via the reinforcing base block 26. At this time, the anti-theft cover 2 rotates around the rotation adjustment hole 22, supported by the rotation support block 11. The rotating anti-theft cover 2 causes a pair of first hexagonal decorative grooves 24 and second hexagonal decorative grooves 25 on it to rotate. Rotation is complete when one of the first hexagonal decorative grooves 24 aligns with one of the screw mounting holes 13, and simultaneously one of the second hexagonal decorative grooves 25 aligns with the other screw mounting hole 13. Then, the connecting plate 1 can be placed on the designated location on the car door, and the first screw 14 and screw connecting groove 15 are inserted into the corresponding screw mounting holes 13 and tightened using a tool. Afterwards, rotating the U-shaped latch 21 causes the anti-theft cover 2 to rotate, so that the rotated fastening screw 23 aligns with the screw connecting groove 15. Finally, the tool can be used to turn the fastening screw 23. Since the fastening screw 23 is screwed into the screw connecting groove 15, the fastening screw 23 is inserted into the screw connecting groove 15, thus preventing the anti-theft cover 2 from rotating on the connecting plate 1. When a thief first removes a pair of fastening screws 23, he will find that the connecting plate 1 and the anti-theft cover 2 are still firmly installed on the car door, thus confusing the thief. Even if the thief rotates the anti-theft cover 2, since the distance from the first screw 14 and the second screw 16 to the rotating support block 11 corresponds to the first hexagonal decorative groove 24 and the second hexagonal decorative groove 25, the tool can only pass through the first hexagonal decorative groove 24 and the second hexagonal decorative groove 25 to disassemble the anti-theft cover 2 so that the first hexagonal decorative groove 24 is completely aligned with the first screw 14 and the second hexagonal decorative groove 25 is aligned with the second screw 16. This will further interfere with the thief and, to a certain extent, prevent and deter theft.

[0029] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
