[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] like Figures 1-2 As shown, a vehicle headlight inspection fixture according to one embodiment of this utility model includes an operating platform 1, with a support leg 2 installed at the lower end of the operating platform 1. A first threaded hole 102 is provided on the operating platform 1, and a limiting rod 3 matching the first threaded hole 102 is installed on the operating platform 1. After the limiting rod 3 is installed on the operating platform 1, a portion protrudes from the upper surface of the operating platform 1. Multiple limiting rods 3 form a contour matching the vehicle headlight, and the vehicle headlight is placed within the formed contour. This achieves simple fixing of the vehicle headlight, ensuring that the position of the vehicle headlight remains the same without changing the position of the limiting rod 3.

[0031] Specifically, such as Figure 3 As shown, the limiting rod 3 includes a first screw 301 with a groove 302. A protrusion 303 is fixedly connected to the end of the first screw 301 furthest from the operating table 1. A rubber ring 4, matching the groove 302, is sleeved on the first screw 301. A limiting block 401, matching the groove 302, is fixedly connected to the inner wall of the rubber ring 4. The limiting block 401 changes the distance between the limiting rod 3 and the headlight, and the limiting block 401 fits against the headlight to further secure it.

[0032] Since the rubber ring 4 is detachable and is generally made of rubber, it is inexpensive to use. For some irregularly shaped car lights, the outer wall of the rubber ring 4 can be cut to match the shape of the car light for fixing.

[0033] like Figures 1-2 As shown, a medium-sized sliding groove 101 is provided on the side wall of the operating table 1. Several pressing structures 5 are slidably connected in the medium-sized sliding groove 101. The pressing structures 5 can apply a downward force to the headlight to further fix the headlight and reduce the headlight shaking during the testing process.

[0034] like Figures 1 to 8 As shown, the pressing structure 5 includes a second screw 6, on which a slider 601 matching the central groove 101 is fixedly connected. The second screw 6 is slidably connected within the central groove 101 via the slider 601. The lower end of the second screw 6 is fixedly connected to the slider 601, and a locking handle 8 is threadedly connected to the lower end of the second screw 6 at the slider 601. One end of the operating table 1 is located between the slider 601 and the locking handle 8. That is, tightening the first nut 9 can fix the second screw 6 and the operating table 1. A handle 7 is fixedly connected to the lower end of the second screw 6 at the locking handle 8. The handle 7 can drive the second screw 6 to slide in the central groove 101. If the slider 601 is circular, the handle 7 can also drive the second screw 6 to rotate within the slider 601.

[0035] like Figures 1 to 8 As shown, a collar 11 is slidably connected to the second screw 6, and a first nut 9 and a second nut 10, which match the collar 11, are threaded onto the second screw 6. The first nut 9 and the second nut 10 are located at the upper and lower ends of the collar 11, respectively. By changing the position of the first nut 9, the position of the collar 11 on the second screw 6 can be changed, while the second nut 10 can fix the collar 11, making it difficult for the collar 11 to rotate on the second screw 6.

[0036] like Figures 1 to 8 As shown, a connecting cylinder 12 is fixedly connected to the collar 11, and a sliding rod 13 is slidably connected inside the connecting cylinder 12. A second threaded hole 1201 is provided at the upper end of the connecting cylinder 12, and a first slot 1301 matching the second threaded hole 1201 is provided on the sliding rod 13. A first bolt 14 matching the second threaded hole 1201 is threadedly connected to the connecting cylinder 12. Tightening the first bolt 14 can fix the connecting cylinder 12 and the sliding rod 13.

[0037] like Figures 1 to 8As shown, a connecting block 15 is fixedly connected to the end of the slide rod 13 away from the connecting cylinder 12. A third threaded hole 1501 is provided on the connecting block 15. A connecting rod 16, matching the third threaded hole 1501, is slidably connected to the connecting block 15. A limit cover 1601 is fixedly connected to the upper end of the connecting rod 16. A spring 17 is sleeved on the connecting rod 16, located between the limit cover 1601 and the connecting block 15. The spring 17 applies a downward force to the connecting rod 16. Normally, the spring 17 can be detachably installed on the limit cover 1601 and the connecting block 15 using a retaining ring, allowing for the removal and replacement of the spring 17.

[0038] like Figures 1 to 8 As shown, a rectangular hole 1502 is provided on the side wall of the third threaded hole 1501, and a convex hole 1602 matching the third threaded hole 1501 is provided on the connecting rod 16. A convex block 18 matching the convex hole 1602 is slidably connected to the connecting rod 16. A fifth threaded hole 1801 is provided on the convex block 18, and a second bolt 19 matching the fifth threaded hole 1801 is threadedly connected to the convex block 18. The second bolt 19 is screwed into the fifth threaded hole 1801 and can contact the bottom wall of the convex hole 1602. By further tightening, the position of the convex block 18 is locked.

[0039] When the connecting block 15 and the connecting rod 16 are used together, first determine the position of the convex block 18. When the connecting rod 16 is not needed to fix the headlight, pull the connecting rod 16 upward so that the position of the convex block 18 is at the upper end of the connecting block 15. Then rotate it at a certain angle so that the position of the second bolt 19 is offset from the position of the rectangular hole 1502. Then release it, and the spring 17 applies a downward force so that the second bolt 19 is at the upper end of the connecting block 15 and is fixed.

[0040] Preferably, a recessed groove matching the second bolt 19 can be formed on the upper surface of the connecting block 15, and the recessed groove can prevent the second bolt 19 from detaching from the connecting block 15.

[0041] like Figure 8 As shown, a rubber pad 20 is installed at the lower end of the connecting rod 16, and a third screw 2001 is fixedly connected to the rubber pad 20. A fourth threaded hole 1603 matching the third screw 2001 is opened on the lower end face of the connecting rod 16. The rubber pad 20 is threadedly connected to the connecting rod 16 through the fourth threaded hole 1603 and the third screw 2001. That is, the rubber pad 20 is replaceable, and its specifications can be selected according to actual usage.

[0042] In use, first, place the vehicle headlight on the operating table 1. Then, according to the contour of the operating table 1, thread the corresponding limiting rod 3 onto the central sliding groove 101, and fit a rubber ring 4 onto the limiting rod 3, so that the rubber ring 4 and the vehicle headlight have an interference fit. With this setting, the position of the vehicle headlight is always the same each time it is placed. When placing the testing equipment, the position of the testing equipment can be fixed and placed in a convenient position, which facilitates the testing of the vehicle headlight and reduces the need to adjust the position of the testing equipment after the vehicle headlight is placed.

[0043] To secure the headlight using the pressing structure 5, first loosen the locking handle 8, then push the handle 7 to slide it on the central groove 101 until the second screw 6 is in the position matching the headlight. Next, adjust the position of the collar 11 up and down until the lower end of the rubber pad 20 is below the headlight's position. Finally, adjust the slide rod 13 so that it slides within the connecting cylinder 12, allowing the lower end of the rubber pad 20 to contact the headlight.

[0044] When removing the headlights, if it is not necessary to use the pressing structure 5 to fix the headlights, simply pull the connecting rod 16 upwards so that the second bolt 19 passes through the connecting block 15. Then rotate it at a certain angle so that the upper end face of the connecting block 15 contacts the second bolt 19. Under the action of the spring 17, the second bolt 19 and the connecting block 15 generate friction, thereby fixing the connecting rod 16.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
