[0002] Neon lamp generally refers to neon lamp. Neon lamp is a bright, energized glass tube or bulb filled with rarefied neon gas or other rare gases. It is a cold cathode gas discharge lamp. A neon lamp tube is a sealed glass tube with electrodes at both ends, which is filled with some low-pressure gas. A voltage of several thousand volts is applied to the electrodes, ionizing the gas in the tube to make it emit light. It is an emerging lighting fixture, named after its large application in urban neon lamps. Neon lamps can be used as indicator lights, sign lights, signal lights, or as lighting for corridors, bedrooms, etc.

[0003] The Chinese patent with the announcement number CN215061659U discloses a neon lamp with a power-off protection function, including a lamp housing, a neon lamp body fixedly mounted on the bottom of the inner wall of the lamp housing, a light-transmitting plate fixedly mounted on the bottom end of the lamp housing, a level fixedly mounted on the middle of the top surface of the lamp housing, a threaded column fixedly mounted on the top surface of the lamp housing, and an adjusting nut threadedly sleeved on the surface of the threaded column. The neon lamp with a power-off protection function adjusts the height of the neon lamp with a power-off protection function by setting the threaded column, the adjusting nut, and the hollow tube to cooperate with each other, and the adjusting nut is rotated to make the threaded column retract into the hollow tube or extend outward, thereby adding a device that facilitates the height adjustment of the neon lamp with a power-off protection function, achieving the goal of facilitating the height adjustment of the neon lamp with a power-off protection function, improving the flexibility of use, meeting the use needs of users, and being more convenient to use.

In this example, the lower end of the telescopic rod 6 is threadedly connected to the lamp housing 1 so as to disassemble it. At the same time, it can also be fixedly connected to the lamp housing 1. A sleeve rod 7 is sleeved on the outer side of the upper end of the telescopic rod 6. A fixing seat 8 is connected to the upper end of the sleeve rod 7. An adjustment shell 9 is provided on one side of the lower end of the sleeve rod 7. A gear 10 is rotatably installed on the inner side of the adjustment shell 9. An arc groove 11 adapted to the gear 10 is provided on the side wall of the lower end of the sleeve rod 7. A plurality of tooth grooves meshing with the gear 10 are provided on one side of the telescopic rod 6.

[0024] In this example, the height adjustment mechanism also includes a block 12, which is rotatably installed on the inner side of the adjusting shell 9, and the block 12 is located on the side of the gear 10 away from the sleeve rod 7, and one end of the block 12 is meshed with the gear 10. A cross slide 13 is provided at the end of the adjusting shell 9 away from the sleeve rod 7, and a slider 14 is provided in the cross slide 13. A slider 15 is symmetrically provided on the outer wall of the slider 14, and the combined structure of the slider 14 and the slider 15 is adapted to the cross slide 13. A pull rod 16 is provided on the outer side of the adjusting shell 9, and a handle is connected to one end of the pull rod 16, and the other end of the pull rod 16 passes through the slider 14 and is hinged to the block 12. A baffle 17, a spring 18 and a baffle 2 19 are sleeved between the block 12 and the slider 14 on the outer side of the pull rod 16, and the baffle 2 19 is fixedly connected to the slider 14. Through the height adjustment mechanism, the height position of the lamp housing 1 can be conveniently and quickly adjusted, which improves the flexibility of use and is more practical. In this example, the connection assembly includes a fixed block 21, and the fixed block 21 is symmetrically arranged on the outside of the filter 5. The outer wall of the lamp housing 1 is symmetrically provided with a slot adapted to the fixed block 21. The fixed block 21 and the relative wall of the slot are both embedded with magnets 22, and the magnetic poles of the two magnets 22 are opposite. A pull ring is connected to one side of the fixed block 21. Through the connection assembly, the filter 5 can be easily disassembled, replaced or cleaned. In this example, a fixed rod 20 is fixedly installed at the top of the adjustment shell 9, and the fixed rod 20 is located between the gear 10 and the block 12. The lower end of the fixed rod 20 conflicts with the upper side wall of the block 12, so as to limit the block 12 and improve the connection and fixing effect of the telescopic rod 6 and the sleeve rod 7. In this example, baffle plate 2 19 is slidably connected to pull rod 16, baffle plate 1 17 is fixedly connected to pull rod 16, and both ends of spring 18 are fixedly connected to baffle plate 17 and baffle plate 2 19 respectively, so that the elastic force of spring 18 can be used to act on block 12, so that it can automatically reset after being squeezed and displaced. In this example, the two magnets 22 are strong magnets, the vent is convex, and a sealing ring is provided between the filter screen 5 and the inner wall of the vent to improve the fixing effect of the filter screen 5 and improve the sealing between the filter screen 5 and the lamp housing 1.

[0025] The working principle of the utility model is as follows: when the height position of the lamp housing 1 needs to be adjusted for use, the lamp housing 1 can be pushed upward to drive the telescopic rod 6 to move upward, so that the upper end of the telescopic rod 6 moves into the sleeve rod 7. At the same time, a plurality of tooth grooves provided on one side of the telescopic rod 6 will drive the meshing gear 10 to rotate, so that the teeth on one side of the gear 10 will squeeze and push the card block 12 on one side to rotate, so that the lower end of the card block 12 moves away from the side of the gear 10. At the same time, the card block 12 will push the pull rod 16 when moving, so that the pull rod 16 drives the baffle 17 and cooperates with the baffle 2 19 to squeeze the spring 18. At the same time, the pull rod 16 will drive the slider 14 and the slider 2 15 to slide in the cross groove 13. When the teeth on the gear 10 that squeeze the card block 12 to move are misaligned with the card block 12, the baffle 17 will be reset under the elastic force of the spring 18, and the baffle 17 will drive the pull rod 16 to reset and push the card block 12 to move. At the same time, the pull rod 16 will also drive the slider 14 to slide in the same direction. The cam 12 is moved step by step, so that one end of the block 12 is meshed with the gear 10 again, thereby limiting and fixing the gear 10, realizing limiting and fixing the telescopic rod 6, preventing the telescopic rod 6 from moving downward, thereby completing the adjustment of the height position of the lamp housing 1; when the neon lamp body 2 needs to adjust the height position of the lamp housing 1 downward, the handle can be pulled to drive the pull rod 16 to move synchronously, thereby pulling the block 12 and the gear 10 apart, and then the telescopic rod 6 can be pulled downward, thereby adjusting the height position of the lamp housing 1 downward, which is convenient to use and has strong practicality. When the filter screen 5 needs to be removed, only the pull ring needs to be pulled to one side to pull the fixing block 21, thereby driving the filter screen 5, so that the two fitted magnets 22 are separated, and the removal of the filter screen 5 is completed, so that the filter screen 5 can be cleaned or replaced. During installation, the filter screen 5 can be directly installed in the vent, and the fixing block 21 can be inserted into the card slot to fit the magnet 22, thereby completing the installation and fixing of the filter screen 5, which is convenient to use and has stronger practicality.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
