[0023] 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.

[0024] Example 1:

[0025] Please see Figure 1-3 This utility model provides a technical solution: a sliding rail type multi-directional positioning car roof light, including a cross plate 1, with multiple side plates 11 fixedly connected to the bottom surface of the cross plate 1, and a sliding groove 12 formed between the inner walls of the multiple side plates 11. A pulley 2 is slidably arranged in the sliding groove 12, and a connecting rod 21 is rotatably arranged in the middle of the pulley 2. A lamp holder 3 is fixedly connected to the bottom end of the connecting rod 21, and a lamp body 31 is fixedly connected to the bottom surface of the lamp holder 3. When it is necessary to adjust the lamp holder 3 and the lamp body 31, the lamp holder 3 and the lamp body 31 are moved. The movement of the lamp holder 3 and the lamp body 31 drives the connecting rod 21 to move. The movement of the connecting rod 21 drives the pulley 2 to move in the sliding groove 12. When it is necessary to adjust by 180 degrees, the lamp holder 3 is moved to the middle of the sliding groove 12 and the lamp holder 3 is rotated. The rotation of the lamp holder 3 drives the connecting rod 21 to rotate on the pulley 2. The user can adjust the device according to the usage requirements.

[0026] Two first rack grooves 32 are provided on both sides of the top surface of the lamp holder 3. A first rack 33 is slidably connected inside the first rack groove 32. The first rack 33 contacts the outer wall of the corresponding side plate 11. Before adjustment, the first rack 33 is moved downwards and moves in the first rack groove 32. When the first rack 33 enters the first rack groove 32, it is convenient for the lamp holder 3 to rotate or move. The first rack 33 contacts the side plate 11 to limit the lamp holder 3, so that the lamp body 31 will not rotate or move when in use.

[0027] Example 2:

[0028] Please see Figure 1-3 This is the second embodiment of the present invention. Based on the previous embodiment, the lamp holder 3 has gears 36 rotatably arranged on both sides inside. Two second rack grooves 34 are opened on both sides of the lamp holder 3. A second rack 35 is slidably connected inside the second rack groove 34. The second rack 35 and the first rack 33 are meshed with the corresponding gears 36. When it is necessary to adjust the lamp holder 3 and the lamp body 31, the second rack 35 is moved. The second rack 35 moves in the second rack groove 34. The movement of the second rack 35 drives the gear 36 to rotate. The rotation of the gear 36 drives the first rack 33 to move. After the first rack 33 enters the first rack groove 32, the lamp holder 3 can be adjusted normally.

[0029] A spring 37 is provided inside the second rack groove 34. The two ends of the spring 37 are fixedly connected to the corresponding second rack 35 and the side wall of the second rack groove 34, respectively. When the second rack 35 is moved, the cooperation between the second rack 35 and the second rack groove 34 compresses the spring 37. When the second rack 35 is no longer under force, the spring 37 uses its elastic force to restore the second rack 35 to its original position.

[0030] A pressing plate 39 is fixedly connected to the ends of the two second racks 35 on one side, and a long strip 38 is fixedly connected between the two second racks 35 on one side; the pressing plate 39 makes it convenient for the user to press, and the gap between the long strip 38 and the pressing plate 39 makes it convenient for the user to hang items.

[0031] A limiting plate 13 is fixedly connected to the bottom of the side plate 11. The limiting plate 13 contacts the bottom surface of the pulley 2. The limiting plate 13 limits the pulley 2 and ensures that the pulley 2 moves normally in the slide groove 12.

[0032] A mounting plate 14 is fixedly connected to the top of the outer wall of the side plate 11, and a damping block 4 is fixedly connected to the top of the first rack 33. The top of the damping block 4 contacts the bottom surface of the corresponding mounting plate 14. When the damping block 4 contacts the mounting plate 14, it can ensure that the lamp holder 3 will not move. Multiple round holes are provided on the mounting plate 14 to facilitate the user to install the device on the roof of the vehicle with screws.

[0033] In use, the user can adjust the direction and position of the device according to their needs. When the lamp body 31 needs to be adjusted on the x-axis, press the pressing plate 39. The pressing plate 39 moves inward, causing the second rack 35 to move within the second rack groove 34. The engagement of the second rack 35 and the second rack groove 34 compresses the spring 37. The movement of the second rack 35 causes the gear 36 to rotate. The rotation of the gear 36 causes the first rack 33 to move within the first rack groove 32. The movement of the first rack 33 causes the damping block 4 to move. When the damping block... 4. After moving away from the mounting plate 14 and into the first rack groove 32, the position of the lamp holder 3 can be moved according to usage requirements. The movement of the lamp holder 3 drives the connecting rod 21 and pulley 2 to move. The pulley 2 moves within the slide groove 12, and the limiting plate 13 helps to limit the pulley 2. The movement of the lamp holder 3 drives the lamp body 31 to move. After adjustment, release the pressing plate 39. The spring 37 uses its elasticity to return the second rack 35 to its original position. The cooperation of the components causes the damping block 4 to re-contact the mounting plate 14, thereby completing the position movement. The lamp body 31 needs to be rotated 180 degrees. When adjusting the lamp holder 3 on the Y-axis, press the pressing plate 39. The components work together to allow the first rack 33 and damping block 4 to enter the first rack groove 32. Move the lamp holder 3 to the center position of the cross plate 1, and rotate the lamp holder 3. The rotation of the lamp holder 3 drives the connecting rod 21 to rotate on the pulley 2. After rotating 180 degrees, release the pressing plate 39. The first rack 33 contacts the side wall of the side plate 11 on the other side, helping to limit the lamp holder 3 and ensure that the lamp holder 3 will not rotate. At the same time, the damping block 4 contacts the bottom surface of the mounting plate 14 on the other side, ensuring that the lamp holder 3... The device will not move. It is installed on the roof of the vehicle via the mounting plate 14. The gap between the long strip 38 and the pressing plate 39 is convenient for users to hang items. In this utility model, users can move the lamp body 31 along the x-axis or rotate the lamp body 31 180 degrees and move it along the Y-axis according to their needs. This allows users to accurately illuminate the interior area of ​​the vehicle. The first rack 33 and the damping block 4 limit the lamp holder 3, ensuring that the lamp holder 3 and the lamp body 31 will not shift or rotate after being moved to the designated location, thus improving the stability of the device.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
