[0029] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] As described in the background section, traditional snap-fit ​​devices are generally one-way locking or insertion devices, which pose a risk of falling off.

[0031] To solve the above problems, such as Figure 1As shown, this utility model discloses a buckle 20 anti-detachment structure, including: buckle 20; buckle seat 10, the buckle seat 10 is provided with a positioning hole 11 for the buckle 20 to be engaged, and a buckle guide groove 12 communicating with the positioning hole 11; anti-detachment part 30, the anti-detachment part 30 is arranged adjacent to the buckle guide groove 12.

[0032] The buckle 20 can slide into the positioning hole 11 through the buckle guide groove 12 and engage with the positioning hole 11. When the buckle 20 is subjected to external force and moves outward from the buckle guide groove 12, it will be blocked by the anti-detachment part 30 and cannot be detached. The anti-detachment structure of the buckle 20 in this embodiment is simple in design, easy to manufacture, simple to operate, and highly reliable.

[0033] In some embodiments, please refer to Figure 2 The buckle guide groove 12 gradually narrows along the direction leading to the positioning hole 11.

[0034] Specifically, the first end of the snap-fit ​​guide groove 12 is connected to the positioning hole 11, and the second end is located near the anti-detachment part 30. The first end has a first width, and the second end has a second width. The second width is greater than the first width, and the snap-fit ​​guide groove 12 gradually narrows from the second end towards the first end.

[0035] The second end is wider to facilitate the buckle 20 entering the buckle guide groove 12, while the first end is narrower to reduce the probability of the buckle 20 sliding out of the positioning hole 11.

[0036] In some embodiments, the width of the connection portion 22 between the snap-fit ​​guide groove 12 and the positioning hole 11 is smaller than the diameter of the positioning hole 11.

[0037] Please continue to refer to this. Figure 2 By setting the width of the connection portion 22 between the buckle guide groove 12 and the positioning hole 11 to be smaller than the diameter of the positioning hole 11, it is possible to prevent the buckle 20 from sliding out of the positioning hole 11 due to external force after it enters the positioning hole 11.

[0038] In some embodiments, the anti-detachment part 30 can be an elastic sheet. When it is necessary to install the buckle 20 onto the buckle seat 10, the buckle 20 can first press down on the spring sheet to expose the entrance of the buckle guide groove 12. At this time, the buckle 20 is moved into the buckle guide groove 12 and continues to move into the positioning hole 11. After the buckle 20 is removed from the spring sheet, the spring sheet returns to its original position and blocks the entrance of the buckle guide groove 12 again, thereby preventing the buckle 20 from falling out of the buckle seat 10.

[0039] In some embodiments, please refer to Figure 1The end of the elastic sheet away from the positioning hole 11 is fixedly connected to the buckle seat 10, and the end close to the positioning hole 11 is the free end.

[0040] Specifically, the buckle seat 10 comprises two parts. The first part is provided with a positioning hole 11 and a buckle guide groove 12, and the second part is provided with a spring sheet. The first and second parts are integrally formed. The end of the spring sheet away from the positioning hole 11 is fixedly connected to the second part of the buckle seat 10, while the end closer to the positioning hole 11 is a free end that can be bent under external force. For example, the buckle 20 can press down the spring sheet and enter the buckle guide groove 12.

[0041] In some embodiments, please refer to Figure 3 The free end of the elastic sheet has a first gap 13 between it and the buckle guide groove 12, and the first gap 13 is smaller than the width of the buckle 20.

[0042] exist Figure 3 In this design, a first gap 13 is provided between the free end of the elastic sheet and the buckle guide groove 12. This arrangement ensures that the free end of the elastic sheet can move. Furthermore, the first gap 13 is smaller than the width of the buckle 20 to prevent the buckle 20 from sliding out of the first gap 13, thus ensuring the anti-detachment function of the anti-detachment part 30.

[0043] In some embodiments, please refer to Figure 4 The buckle 20 includes a buckle body 21, a connecting part 22, and a snap-fit ​​part 23, wherein the width of the connecting part 22 is less than or equal to the width of the buckle guide groove 12, and the width of the buckle body 21 and the snap-fit ​​part 23 is greater than the diameter of the positioning hole 11.

[0044] The connecting portion 22 of the buckle 20 is located between the engaging portion 23 and the buckle body 21, and is used to connect the two. Furthermore, when the buckle 20 is installed onto the buckle seat 10, the connecting portion 22 of the buckle 20 slides in conjunction with the buckle guide groove 12, with the engaging portion 23 and the buckle body 21 located on opposite sides of the buckle guide groove 12.

[0045] By setting the width of the connecting part 22 to be less than or equal to the width of the buckle guide groove 12, and setting the width of the buckle body 21 and the snap-fit ​​part 23 to be greater than the diameter of the positioning hole 11, it can be ensured that the buckle 20 can slide into the positioning hole 11 through the buckle guide groove 12 and will not fall off from the positioning hole 11.

[0046] In some embodiments, the width of the latch body 21 and the latching portion 23 is greater than the width of the latch guide groove 12. This configuration prevents the latch 20 from falling out of the latch guide groove 12.

[0047] This utility model also discloses a lamp, including the buckle 20 anti-detachment structure in any of the above embodiments.

[0048] The latch 20 can slide into the positioning hole 11 through the latch guide groove 12 and engage with the positioning hole 11. When the latch 20 is subjected to external force and moves outward from the latch guide groove 12, it will be stopped by the anti-detachment part 30 and cannot be detached. Applying this anti-detachment structure of the latch 20 in lighting fixtures can simplify the fixture structure, reduce manufacturing costs, and improve the reliability of the lighting fixtures.

[0049] In some embodiments, the lighting fixture includes vehicle lights.

[0050] Optionally, the above-mentioned lighting fixtures may also include other types, such as household lighting fixtures or lighting fixtures used in some large public places, and this utility model does not limit them.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
