Description

Technical Field

[0001] This utility model relates to the field of lighting installation technology, and in particular to a lighting fixture mounting base. Background Technology

[0002] In existing technology, the structure of a lamp typically includes a light-transmitting lampshade and a base for mounting a circuit board. The mounting base is usually fixed to the wall or ceiling. However, during the construction of a building, the plane of the wall or ceiling cannot be guaranteed to be completely level, resulting in gaps between the base and the wall or ceiling after installation. Insects and other flying creatures can enter the lamp through these gaps, which can affect the circuit board on the base, making it difficult to clean and affecting the lifespan of the lamp.

[0003] Chinese patent publication number CN218936230U discloses a mounting base for an LED flat panel light. It has low installation technical requirements, allows for easy adjustment to obtain the optimal installation position, and improves reliability. The base includes a fixed circular seat, bolt slots, a rotating outer ring, ball bearings, a rotating inner ring, an LED flat panel light mounting base, screw holes, a tightening screw sleeve, a tightening screw rod, and a handle. Multiple sets of bolt slots are evenly arranged on the inner outer ring side of the fixed circular seat. The bottom center of the fixed circular seat connects to the top of the rotating outer ring. Multiple sets of ball bearings pass through the inner side of the rotating outer ring. The bead is rotatably connected to the outer wall of the rotating inner ring. The bottom end of the rotating inner ring is connected to the middle of the top of the LED flat panel light mounting base. The bottom end of the LED flat panel light mounting base is provided with multiple sets of screw holes. Multiple sets of tightening screw sleeves are evenly connected to the outer end of the LED flat panel light mounting base. Each set of tightening screw sleeves is screwed with a set of tightening screws. The bottom end of each set of tightening screws is connected to the middle of the top of a set of handles. When the above mounting base is installed on the top of the wall, the wall surface is uneven, which causes gaps between the mounting base and the wall surface, making it easy for flying insects to enter and affecting the service life of the light fixture.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0020] See Figures 1 to 5 This utility model provides a lamp mounting base, which includes: a base 1, a sealing strip 21 surrounding the base 1; and an abutment assembly disposed on the base 1. The abutment assembly includes a driving component, a ring 3 rotatably connected to the base 1, several blocks 5 disposed on the ring 3, and rotating shafts 6 rotatably connected to the blocks 5. Each end of the rotating shafts 6 is provided with a cam 61 and a gear 62. The driving component drives the gears 62 to rotate, and the cam 61 abuts against the sealing strip 21. The beneficial effects of this utility model are: the sealing strip 21 prevents flying insects from crawling into the lamp from the gap between the base 1 and the wall, thus avoiding interference with the circuit board on the lamp mounting base and improving the lamp's lifespan; the abutment assembly controls the cam 61 to abut against the sealing strip 21, ensuring the sealing strip 21 is tightly against the wall surface, making it suitable for walls with varying flatness errors and improving the device's practicality.

[0021] See Figures 1 to 5 Preferably, the driving component of this utility model is a gear ring 4, which is fixedly connected to a rotating ring 7 and a circular ring 3 respectively. Both rotating rings 7 are rotatably connected to the base 1. The gear ring 4 meshes with several gears 62, and the gear ring 4 can drive several gears 62 to rotate simultaneously.

[0022] See Figures 1 to 5 In addition, a push plate 31 is fixedly connected to the ring 3 of this utility model. The push plate 31 is located outside the base 1. A limiting block 41 is provided on the gear ring 4. The limiting block 41 is located outside the push plate 31. The push plate 31 can control the rotation of the ring 3 and adjust the contact position between the cam 61 and the sealing strip 21. The limiting block 4 can control the rotation of the gear ring 4. Both the limiting block 4 and the push plate 31 are provided with the same positioning hole to ensure that the gear ring 4 is fixed by the positioning pin after rotating to the set position, thus preventing the gear ring 4 from shifting.

[0023] In specific implementation: The push plate 31 and the limiting block 41 drive the ring 3 and the gear ring 4 to rotate synchronously. Several cams 61 are set above the part of the base 1 with a large gap between it and the wall. At this time, the push plate 31 controls the ring 3 to not rotate, and controls the gear ring 4 to rotate relative to the ring 3, so as to drive the several cams 61 to squeeze the sealing strip 21. After the gear ring 3 rotates to the set position, the limiting block 41 and the push plate 31 are provided with several positioning holes. Positioning pins are inserted into the positioning holes to ensure that the gear ring 4 and the ring 3 do not rotate relative to each other. At the same time, the friction between the several cams 61 and the sealing strip 21 ensures that the ring 3 does not move.

[0024] See Figures 1 to 5 Furthermore, the base 1 of this utility model is provided with a plurality of settling holes 11, each of the plurality of settling holes 11 is provided with a cylinder 12, and each of the plurality of cylinders 12 is slidably connected with a connecting piece 22. An elastic element 8 is provided on the outer sleeve of each of the plurality of cylinders 12.

[0025] See Figures 1 to 5 Even better, all of the connecting pieces 22 of this utility model are fixedly connected to the fixing ring 2, and a sealing strip 21 is adhered to the outside of the fixing ring 2.

[0026] Working principle: The base 1 is fixed to the top of the wall with bolts. The control push plate 31 drives the ring 3 to rotate. The ring 3 drives several blocks 5 to move. Each block 5 is rotatably connected to a rotating shaft 6. The two ends of the rotating shaft 6 are respectively equipped with cams 61 and gears 62. The cams 61 are placed in the gap between the base 1 and the wall. The limit block 41 is pushed, which drives the gear ring 4 to rotate. The gear ring 4 drives the gears 62 to rotate, thereby driving the cams 61 to rotate and abut against the sealing strip 21. At this time, the connecting pieces 22 on the fixing ring 2 slide on the cylinder 12, and the connecting pieces 22 compress the elastic element 8 to prevent the sealing strip 21 from separating from the fixing ring 2. After being abutted, the sealing strip 21 is tightly attached to the wall, which plays a sealing role and prevents flying insects from crawling into the lamp through the gap between the base 1 and the wall.

[0027] In summary, the invention includes: a base, a sealing strip surrounding the base; and an abutment assembly disposed on the base, the abutment assembly comprising a driving component, a ring rotatably connected to the base, several blocks disposed on the ring, and rotating shafts rotatably connected to the blocks, wherein each end of the rotating shafts is provided with a cam and a gear, the driving component drives the gears to rotate, and the cam abuts against the sealing strip. The beneficial effects of this invention are: the sealing strip prevents flying insects from crawling into the lamp fixture through the gap between the base and the wall, thus avoiding interference with the circuit board on the lamp fixture mounting base and improving the lamp fixture's lifespan; the abutment assembly controls the cam to abut against the sealing strip, ensuring the sealing strip is tightly against the wall surface, making it suitable for walls with varying flatness errors and improving the device's practicality.
