[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figures 1 - 5, an embodiment provided by the present utility model: a C-shaped lamp for adjusting the strength of a lamp housing, comprising a housing 1, a long rotating shaft 14 and a connecting rod 18. A hollow box 3 is fixedly connected to the right end of the housing 1. A transmission rod 4 is rotatably connected to the middle and lower part on the right side of the hollow box 3. The left end of the transmission rod 4 penetrates through the hollow box 3 and is fixedly connected to a worm 5. A rotating rod 6 is rotatably connected to the top end inside the hollow box 3. A worm gear 7 is fixedly connected to the middle and lower part on the outer side of the rotating rod 6. The worm gear 7 is meshed with the worm 5. A flat gear 8 is fixedly connected to the bottom end of the rotating rod 6. A hollow column 9 is fixedly connected to the right end inside the hollow box 3. A transmission port 11 is opened at the left end of the rear side of the hollow column 9. A cylindrical rack 10 is slidably connected inside the hollow column 9. The cylindrical rack 10 is meshed with the flat gear 8. A fixing plate 12 is fixedly connected to the left end of the cylindrical rack 10. First rotating shafts 13 are rotatably connected to both the upper and lower sides of the fixing plate 12. Concave plates 15 are arranged on both the front and rear sides of the bottom of the housing 1. The two concave plates 15 are respectively rotatably connected to the front and rear sides of the bottom of the housing 1 through a plurality of long rotating shafts 14. Fixed cards 16 are fixedly connected to the adjacent sides on the right ends of the two concave plates 15. Second rotating shafts 17 are rotatably connected inside the two fixed cards 16. The two second rotating shafts 17 are respectively connected to the corresponding first rotating shafts 13 through connecting rods 18. Lamp strips 19 are slidably connected to the inner sides of the two concave plates 15. An adjusting mechanism 2 is arranged at the left end of the housing 1. The adjusting mechanism 2 is used to conveniently adjust the intensity of the light;

[0034] Specifically, when the lamp strip 19 needs to be replaced, rotate the transmission rod 4. During the rotation of the transmission rod 4, the worm 5 will be driven to rotate. As the worm 5 rotates, the worm gear 7 will also rotate accordingly. The rotational movement of the worm gear 7 is transmitted to the flat gear 8 through the rotating rod 6, causing the flat gear 8 to start rotating. The flat gear 8 is meshed with the cylindrical rack 10 through the transmission port 11 opened at the rear side of the hollow column 9, so that the cylindrical rack 10 will move to the left due to the rotation of the flat gear 8. As the cylindrical rack 10 moves to the left, the first rotating shaft 13 will also move to the left accordingly. One end of the connecting rod 18 is connected to the fixed card 16 through the second rotating shaft 17. Therefore, the connecting rod 18 will push the fixed card 16 to move to both sides due to the movement of the first rotating shaft 13. The two concave plates 15 are connected to the housing 1 through the long rotating shafts 14. When being pushed by the fixed card 16, the concave plates 15 will flip outwards. At this time, the lamp strip 19 can be easily pulled out from the inside of the concave plate 15, facilitating disassembly, greatly improving the working efficiency of the user, and meeting the needs of the user.

[0035] Refer to Figures 3 - 6, the adjusting mechanism 2 includes a hollow box 201. The hollow box 201 is fixedly connected to the left end of the outer shell 1. A motor 202 is fixedly connected to the lower middle part on the left side of the hollow box 201. The output end of the motor 202 penetrates through the hollow box 201 and is fixedly connected to a driving bevel gear 203. A threaded rod 204 is rotatably connected to the inner bottom end of the hollow box 201. A driven bevel gear 205 is fixedly connected to the middle lower part on the outer side of the threaded rod 204. The driven bevel gear 205 is meshed with the driving bevel gear 203. A support rod 206 is threadedly connected to the middle upper part on the outer side of the threaded rod 204. A plurality of support pieces 207 are fixedly connected to the outer periphery of the support rod 206 at equal intervals. The bottoms of the plurality of support pieces 207 are all fixedly connected to the same reflector 208. A chute 20 is provided on the adjacent inner sides of the hollow box 201 and the hollow box 3. The left and right ends of the support piece 207 are respectively slidably connected to the inner parts of the two chutes 20;

[0036] Specifically, when the light needs to be adjusted, first start the motor 202. The start of the motor 202 will drive the driving bevel gear 203 to start rotating. As the driving bevel gear 203 rotates, the driven bevel gear 205 will also start to rotate accordingly. The rotational movement of the driven bevel gear 205 is further transmitted to the threaded rod 204, causing it to also start rotating. The two ends of the support rod 206 are fixed in the chute 20. Therefore, when the threaded rod 204 rotates, the support rod 206 will move upward along the thread due to the rotation of the threaded rod 204. Since the reflector 208 is connected to the support rod 206 through the support piece 207, the reflector 208 will also move upward as the support rod 206 rises. As the reflector 208 moves upward, the distance between it and the light bar 19 gradually increases, resulting in a decrease in the intensity of the reflected light. At this time, the brightness of the C-shaped lamp will decrease accordingly. On the contrary, if the reflector 208 moves downward, the distance between it and the light bar 19 will decrease, and the intensity of the reflected light will increase, thereby increasing the brightness of the C-shaped lamp. At this time, the adjustment of the C-shaped lamp can be realized, greatly increasing the practicability and flexibility of the device. The model of the motor 202 is 560JH570.

[0037] Refer to Figures 3 - 6 , a plurality of reinforcing plates 22 are fixedly connected to the inner top end of the outer shell 1 at equal intervals. Threading holes 23 are provided on the upper left and right sides of the right ends of the plurality of reinforcing plates 22. A U-shaped bridge 24 is fixedly connected to the top of the outer shell 1. A plurality of brackets 25 are arranged in the U-shaped bridge 24 at equal intervals. A plurality of first screws 26 are provided on the front and rear sides of the U-shaped bridge 24. One ends of the plurality of first screws 26 penetrate through the U-shaped bridge 24 and are threadedly connected to the corresponding brackets 25. The front and rear sides of the tops of the plurality of brackets 25 are fixedly connected to a suspension rod 27;

[0038] Specifically, the structural strength of the device can be increased by the reinforcing plate 22. A wire threading hole 23 is provided on the reinforcing plate 22 to facilitate the wiring work of the device. The U-shaped bridge 24 provides a base for fixing the device. The first screw 26 is used to fix the bracket 25, and the hanging rod 27 fixed on the bracket 25 facilitates the installation and fixation of the device.

[0039] Refer to Figure 1 , a groove 29 is opened on the right side of the top of the housing 1. Power supplies 28 are arranged on the front and rear sides of the inner bottom end of the groove 29. Fixing pieces 30 are fixedly connected to the peripheries of the bottoms of the two power supplies 28. Second screws 21 are threadedly connected to the tops of the multiple fixing pieces 30. The bottoms of the multiple second screws 21 penetrate through the corresponding fixing pieces 30 and are threadedly connected to the bottom of the groove 29;

[0040] Specifically, the design of the two power supplies 28 can more effectively provide the required power support for the device. The power supplies 28 are fixed by the multiple fixing pieces 30 and the second screws 21 to ensure that the power supplies 28 will not be displaced or loosened during operation.

[0041] Working principle: When the light of the device is abnormal and the light bar 19 needs to be replaced, rotate the transmission rod 4. The transmission rod 4 will drive the worm 5 to rotate. At this time, the worm gear 7 will rotate accordingly. The rotation of the worm gear 7 will drive the spur gear 8 to rotate together through the rotating rod 6. Since the spur gear 8 meshes with the cylindrical rack 10 through the transmission port 11 opened at the rear of the hollow column 9, the cylindrical rack 10 will move to the left due to the rotation of the spur gear 8. At this time, the first rotating shaft 13 will move to the left accordingly. Since one end of the connecting rod 18 is connected to the fixed clamp 16 through the second rotating shaft 17, the connecting rod 18 will push the fixed clamp 16 to move to both sides due to the movement of the first rotating shaft 13. At this time, the concave plates 15 on both sides will be pushed to turn outwards because they are connected to the housing 1 through the long rotating shaft 14. At this time, the light bar 19 can be pulled out from the inside of the concave plate 15, and the light bar 19 can be conveniently disassembled;

[0042] And when the light needs to be adjusted, the motor 202 starts to drive the driving bevel gear 203 to rotate. At this time, the driven bevel gear 205 rotates accordingly. The rotation of the driven bevel gear 205 will drive the threaded rod 204 to rotate. Since the two ends of the support rod 206 are limited by the sliding grooves 20, when the threaded rod 204 rotates, the support rod 206 will move upward due to its rotation. Since the reflector 208 is connected to the support rod 206 through the support piece 207, the reflector 208 will move upward accordingly. The reflector 208 moves upward and the distance from the light bar 19 becomes farther, and the reflected light weakens. At this time, the light of the C-shaped lamp can be weakened. On the contrary, when the reflector 208 moves downward, the light of the C-shaped lamp can be enhanced, and the light adjustment of the C-shaped lamp can be realized.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
