[0035] Example 1

[0036] like Figure 1-4 As shown, the present invention proposes an eye-protecting classroom lamp, including a lamp holder 1, a lamp tube 2 inside the lamp holder 1, two traction wires 3 fixedly installed on the top of the lamp holder 1, a reflector 4 for light reflection movably installed on the outside of the lamp holder 1, a rotating shaft 6 fixedly installed on the inner walls of both sides of the reflector 4, the two rotating shafts 6 being movably connected to the two sides of the lamp holder 1 respectively, mounting holes on both sides of the lamp holder 1, bearings fixedly installed in the two mounting holes, the inner ring of the bearings being fixedly sleeved on the rotating shafts 6, a through groove 5 on the top inner wall of the reflector 4, and an adjustment structure 7 for adjusting the angle of the reflector 4 on one side of the lamp holder 1 and the reflector 4.

[0037] The adjustment structure 7 includes an adjustment disc 703 for rotation and a sleeve 701 for installation. The sleeve 701 is fixedly connected to one side of the lamp holder 1. A connecting rod 702 is fixedly provided on one side of the adjustment disc 703. One end of the connecting rod 702 is fixedly connected to the reflector 4. Multiple rectangular plates 704 are fixedly provided on the outside of the adjustment disc 703. A telescopic rod 706 is movably provided inside the sleeve 701. Two sliding grooves are provided on the inner wall of the sleeve 701. Two sliders 708 are fixedly provided on the outside of the telescopic rod 706. The sliders 708 are movably connected to the sliding grooves. A positioning hole 705 is provided on the sleeve 701. A storage hole 709 is provided on the telescopic rod 706. The inner wall of the storage hole 709 is provided with... Two limiting grooves 710 are provided. One end of the telescopic rod 706 is welded with a positioning plate 707. The width of the positioning plate 707 is greater than the length of the connecting rod 702. The telescopic rod 706 is provided with a positioning rod 714 for locking. A spring 711 is fixedly installed in the storage hole 709. One end of the spring 711 is welded with a guide plate 712. Two limiting blocks 713 are fixedly installed on the outside of the guide plate 712. The limiting blocks 713 and the limiting grooves 710 are movably connected. The setting of the limiting blocks 713 and the limiting grooves 710 can limit the position of the positioning rod 714 and prevent the positioning rod 714 from separating from the sleeve 701. One end of the positioning rod 714 is fixedly connected to one side of the guide plate 712.

[0038] In this embodiment, when the angle of the reflector 4 needs to be adjusted, the positioning rod 714 is pressed inward, which in turn presses the guide plate 712. The guide plate 712 then presses the spring 711. When the positioning rod 714 is fully retracted into the storage hole 709, the telescopic rod 706 is pulled outward. The telescopic rod 706 then drives the locking plate 707 to disengage from between the two rectangular plates 704. Then, the adjusting disk 703 is rotated. The adjusting disk 703 drives the reflector 4 through the connecting rod 702, thereby adjusting the angle of the reflector 4. After adjustment, the locking plate 707 is moved inward. The internal push causes the locking plate 707 to drive the telescopic rod 706, which in turn drives the positioning rod 714 to move. When the positioning rod 714 moves to the positioning hole 705, the spring 711 pushes the guide plate 712, which in turn pushes the positioning rod 714 to reset it and pop out from the positioning hole 705, thus positioning the locking plate 707. At this time, the locking plate 707 is locked between the two rectangular plates 704, thus positioning the adjusting plate 703. This effectively prevents the angle of the reflector 4 from changing due to the rotation of the adjusting plate 703.

[0039] Example 2

[0040] like Figure 1-5As shown, based on Embodiment 1, the top of the reflector 4 is provided with a dustproof structure 8. The dustproof structure 8 includes two mounting bases 801 for installation. Both mounting bases 801 are fixedly connected to the top of the reflector 4. Each mounting base 801 has a movable locking block 806. The top of each locking block 806 is fixedly provided with two vertical rods 805. The top of the two sets of vertical rods 805 is fixedly provided with the same dustproof cover 802. The top of the dustproof cover 802 is provided with two passage slots 803. The passage slots 803 allow the traction line 3 to pass through during disassembly and assembly. The two passage slots 803 have two openings on both sides. Rubber dustproof sheets 804 are installed on the walls. The rubber dustproof sheets 804 are deformable and can fit tightly against the traction line 3 to prevent dust from passing through the channel 803 and falling onto the lamp holder 1. The dust cover 802 is located on top of the reflector 4 and the lamp holder 1. It can prevent dust in the air from falling on the top of the lamp holder, ensuring the cleanliness of the top of the lamp holder 1 and ensuring the heat dissipation performance of the equipment. When it is necessary to clean the dust on the top of the dust cover 802, pull the two sets of vertical rods 805 outward. The vertical rods 805 drive the locking block 806. When the locking block 806 separates from the mounting base 801, the dust cover 802 can be removed for cleaning.

[0041] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
