[0002] With the development of China's economy and the improvement of people's living standards, cars have become an indispensable means of transportation for some people. Carpets are installed in many places in cars, such as the footwell in the passenger compartment and the storage area in the trunk. The placement of these carpets can protect the car passenger compartment floor and the trunk floor, and also keep them clean. The carpets need to be fixed in place, otherwise they will move when people put their feet on them, resulting in inaccurate positioning.

[0003] Existing carpet trim strips are often fixed to the mounting holes of the car body using clips. The carpet trim strip support structure passes through the mounting holes of the car body to fix the carpet and provide support for the carpet trim strip.

[0004] However, traditional carpet strip installations use clips for fixing, requiring disassembly for internal cleaning and maintenance. Disassembly is cumbersome and inconvenient for cleaning and maintenance of the carpet strip's interior, thus limiting its applicability. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 6 This utility model provides a technical solution: a car door carpet trim strip;

[0026] Example 1:

[0027] To facilitate the installation and removal of the car carpet trim, a first spring 4 is fixedly connected to the bottom surface of the snap-fit ​​connector 3. A fixing plate 5 is fixedly connected to one end of the first spring 4. A first pull rod 6 is fixedly connected to the side surface of the fixing plate 5. A compression sleeve 8 is fitted onto the outer surface of the first pull rod 6. A first pull block 7 is fixedly connected to the side of the first pull rod 6 away from the fixing plate 5. A first mounting plate 10 and a second mounting plate 14 are fixedly connected to the inner wall of the snap-fit ​​connector 3. A connecting rod 13 is fixedly connected to the inner side of the second mounting plate 14. A movable block 12 is movably connected to the outer surface of the connecting rod 13. A fixing block 15 is fixedly installed on the side surface of the movable block 12. A second spring 11 is fixedly connected to the lower surface of the first mounting plate 10. The bottom end of the second spring 11 is connected to the upper surface of the movable block 12. By pulling the first pull block 7, the first pull rod 6 is driven to the locking position. The external movement of the fastener 3 causes the fixing plate 5 and the compression sleeve 8 to move. Through the tension of the first spring 4, the part that is in contact with the lower surface of the compression sleeve 8 and the fixing block 15 can be separated. Through the second spring 11, the movable block 12 drives the fixing block 15 to retract into the fastener 3. By inserting the fastener 3 into the mounting hole 2 in the carpet strip cover plate 1, the first pull block 7 is released. Through the rebound energy of the first spring 4, the first pull rod 6 and the compression sleeve 8 can be reset. During the reset process of the compression sleeve 8, the lower surface of the fixing block 15 is squeezed, thereby causing the fixing block 15 to move outward and lock into the fastener 3. This can greatly reduce the time required to replace or clean the carpet, thereby improving work efficiency, helping to maintain a clean and hygienic environment in the car, and extending the service life of the carpet.

[0028] Example 2:

[0029] Based on Embodiment 1, in order to disassemble the installed snap-fit ​​connector 3, a first limiting plate 16 is fixedly installed on the side of the snap-fit ​​connector 3 away from the first spring 4. The inner surface of the first limiting plate 16 has a cavity 17, and the inner surface of the cavity 17 is provided with a limiting self-locking mechanism. The limiting self-locking mechanism includes: a square groove 21, which is opened on the outer surface of the first pull rod 6. A square limiting block 20 is provided on the inner surface of the square groove 21. A second pull rod 18 is fixedly installed on the upper surface of the square limiting block 20. A return spring 19 is sleeved on the outer surface of the second pull rod 18. A second pull block 22 is fixedly installed on the side of the second pull rod 18 away from the square limiting block 20. A second limiting plate 23 is fixedly installed on the upper surface of the first limiting plate 16. By pulling the second pull rod 18, the square limiting block 20 is moved to the outside of the snap-fit ​​connector 3 through the return spring 19, thereby disengaging the square limiting block 20 from the square groove 21 and quickly disassembling it.

[0030] Working principle: When installing carpet strips using this device, pulling the first pull block 7 moves the first pull rod 6 outwards towards the snap-fit ​​connector 3, thereby moving the fixing plate 5 and the extrusion sleeve 8. The tension of the first spring 4 allows the part of the extrusion sleeve 8 that is in contact with the lower surface of the fixing block 15 to disengage. The second spring 11 causes the movable block 12 to retract the fixing block 15 into the snap-fit ​​connector 3. By inserting the snap-fit ​​connector 3 into the mounting hole 2 in the carpet strip cover plate 1, releasing the first pull block 7 allows the first pull rod 6 to move due to the rebound energy of the first spring 4. When the compression sleeve 8 is reset, the lower surface of the fixing block 15 is compressed during the reset process, thereby causing the fixing block 15 to move outward of the snap-fit ​​connector 3 and lock. This can greatly reduce the time required to replace or clean the carpet, thereby improving work efficiency and helping to maintain a clean and hygienic environment in the vehicle and extend the service life of the carpet. Secondly, when disassembling the snap-fit ​​connector 3, the square limiting block 20 is moved outward of the snap-fit ​​connector 3 by pulling the second pull rod 18 through the reset spring 19, thereby causing the square limiting block 20 to disengage from the square groove 21, thus enabling quick disassembly.
