[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-3 The utility model provides an embodiment: a lifting lighting device for a power box, including a fixing rod 3, a slot 21 is provided at the top of the fixing rod 3, a plug block 16 is slidably connected inside the slot 21, a lamp holder 2 is fixedly connected to the top of the plug block 16, a turntable 14 is rotatably connected inside the lamp holder 2, a lighting lamp 1 is fixedly connected to the front end of the turntable 14, slots 19 are provided on both sides of the inner wall of the slot 21, a fixing block 11 is slidably connected inside the two slots 19, one end of the two fixing blocks 11 is fixedly connected to the pull rod 20, and fixing grooves 12 are provided on both sides of the plug block 16, and one end of the fixing block 11 is slidably connected inside the fixing groove 12. After the plug block 16 is inserted into the slot 21, the fixing block 11 is pushed so that the fixing block 11 enters the fixing groove 12 to fix the lamp holder 2.

[0032] A spring 22 is wrapped around the outside of the pull rod 20. There is no connection between the spring 22 and the pull rod 20. One end of the two springs 22 is fixedly connected to one end of the fixing block 11 close to the pull rod 20. The spring pushes the fixing block 11 into the fixing groove 12 to connect the lamp holder 2 and the fixing rod 3.

[0033] Mounting grooves 17 are provided at both ends of the top and bottom of one side of the inner wall of the lamp holder 2, and a plurality of evenly distributed limiting grooves 15 are provided on one side of the turntable 14. A spring 18 is fixedly connected to one side of the inner wall of the two mounting grooves 17, and the other ends of the two springs 18 are fixedly connected to the limiting blocks 13, and the other ends of the two limiting blocks 13 are slidably connected to the inside of the limiting grooves 15. Rotating the lighting lamp 1 causes the turntable 14 to rotate inside the lamp holder 2. Since the limiting grooves 15 and the limiting blocks 13 are both set to be semicircular, the side walls of the limiting grooves 15 will squeeze the limiting blocks 13 when the turntable 14 rotates. Since the side where the limiting blocks 13 contact the limiting grooves 15 is an arc-shaped limiting groove 15, the limiting grooves 15 will compress the limiting blocks 13 to retract, thereby adjusting the angle of the lighting lamp 1. After the adjustment is completed, the spring 18 will push the limiting blocks 13 into the inside of the limiting grooves 15 to fix the turntable 14.

[0034] A cavity 5 is provided on one side of the top of the box body 9, and a sleeve 4 is slidably connected inside the cavity 5. The sleeve 4 is threadedly connected to the outside of the fixing rod 3. By rotating the sleeve 4, the fixing rod 3 can slide upward inside the sleeve 4 and extend out of the sleeve 4, thereby adjusting the height of the lighting lamp 1.

[0035] A placement groove 7 is opened in the middle of the top of the box body 9, and a wire groove 6 is opened on one side of the front end of the top of the box body 9. The sleeve 4 is pulled out from the cavity 5 and the base is removed from the top of the fixing rod 3. At the same time, the fixing rod 3 is retracted into the sleeve 4, and then the sleeve 4 is placed in the placement groove 7 to store the sleeve 4. The wire groove 6 can be used to store the connecting wires that provide power to the lighting lamp 1.

[0036] A groove 8 is provided in the middle of the top of the box body 9 , and the disassembled lighting lamp 1 together with the lamp holder 2 are sequentially placed into the groove 8 to store the lighting lamp 1 .

[0037] A box cover 10 is hinged on the rear side of the top of the box body 9, and a bandage is fixed to the front end of the box cover 10 by bolts, and the bandage can be used to fix the photovoltaic panel. Ventilation holes are provided on both sides of the top of the box body 9, and the ventilation holes can be used to dissipate heat from the electrical components inside the box body 9. A power supply hole is provided on one side of the top of the box body 9. The connecting wire that powers the lighting lamp 1 is inserted into the power supply hole to provide power to the lighting lamp 1, and the box body 9 can be sealed by rotating the box cover 10.

[0038] Working principle: After opening the box cover 10, take out the sleeve 4 in the placement groove 7 and insert it into the cavity 5, then pull the pull rod 20 to retract the fixing block 11 and take out the lighting lamp 1 in the groove 8, then extend the insert block 16 into the slot 21, release the pull rod 20 to allow the spring 22 to push the fixing block 11 into the fixing groove 12, so as to fix the lamp holder 2. When it is necessary to adjust the height of the lighting lamp 1, the sleeve 4 can be rotated to make the fixing rod 3 slide upward inside the sleeve 4 and extend out of the sleeve 4, thereby adjusting the height of the lighting lamp 1, and when it is necessary to adjust the angle of the lighting lamp 1, the lighting lamp 1 can be rotated to make the turntable 14 rotate inside the lamp holder 2. Because the limit groove 15 and the limit block 13 are both set as semicircular, When the turntable 14 rotates, the side wall of the limit groove 15 will squeeze the limit block 13. Since the side where the limit block 13 contacts the limit groove 15 is an arc, the limit groove 15 will force the limit block 13 to retract, thereby adjusting the angle of the lighting lamp 1. After the adjustment is completed, the spring 18 will push the limit block 13 into the limit groove 15 to fix the turntable 14. When the lighting lamp 1 needs to be replaced and repaired, the fixing block 11 retracts and the lamp holder 2 is lifted upward by pulling the pull rod 20, so that the insert block 16 withdraws from the slot 21, so that the lighting lamp 1 can be removed from the top of the fixing rod 3, which is convenient for the staff to repair it. At the same time, it can prevent the lamp holder 2 from being fixed by screws and the screws from being accidentally lost when the lamp holder 2 is removed.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
