Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting technology, and more specifically, to a screwless quick-replacement fixing component for LED lighting fixtures. Background Technology
[0002] In LED lighting fixtures, through holes are needed to secure the driver to the electrical board, and then screws and nuts are used for tightening. However, over time, the screws and nuts may rust or strip, making disassembly difficult. Utility Model Content
[0003] This utility model proposes a screwless quick-replacement fixing component, the purpose of which is to solve the problem of difficult disassembly caused by rust or stripped screws and nuts.
[0004] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:
[0005] A screwless quick-replacement fixing component includes a housing and a positioning rod. The housing is hollow, with an L-shaped groove formed by a vertical adjustment groove and a horizontal positioning groove on its side wall. A through hole is formed on the bottom surface of the housing. Multiple separate claws extend downwards around the through hole. The positioning rod is located within the housing. A protruding stop block is provided on the side wall of the positioning rod, and the stop block is located in the L-shaped groove. When the stop block is located in the horizontal positioning groove, the bottom of the positioning rod penetrates the through hole and pushes against each claw, forming a locked state. When the stop block is located in the vertical adjustment groove, the bottom of the positioning rod enters the housing, and the claws are in an unlocked state where they can retract inwards under force.
[0006] Preferably, the vertical adjustment groove is provided with a limiting structure.
[0007] Preferably, the upper end of the positioning rotary rod is provided with a first holding plate.
[0008] Preferably, a second holding plate is provided on the side wall of the casing.
[0009] Preferably, the inner side of the housing is provided with a recessed groove, and the positioning rod is provided with a circumferential protrusion. When the positioning rod is lifted in the vertical adjustment groove under force, the protrusion is locked in the groove for positioning.
[0010] By adopting the above technical solution, the screwless quick-replacement fixing component of this utility model can connect the drive and electrical boards, act as a screw, and realize both locked and unlocked states, which facilitates quick replacement and will not rust and become impossible to disassemble. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of the unlocked state structure according to an embodiment of the present invention;
[0012] Figure 2 This is a schematic diagram of the locking state structure of one embodiment of the present invention;
[0013] Figure 3 This is a schematic diagram illustrating the use of the drive and electrical board in this embodiment. Detailed Implementation
[0014] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0015] See Figures 1-3 As shown, the screwless quick-replacement fixing assembly 1 of this utility model is used to connect the drive 2 and the electrical board 3. Of course, this fixing assembly is not only suitable for fixing the drive, but also for other components such as inverters and sensors that need to be fixed to the inside of the lamp with screws. The screwless quick-replacement fixing assembly 1 includes a housing 11 and a positioning screw rod 12.
[0016] like Figure 1 As shown, the interior of the housing 11 is hollow. An L-shaped groove, consisting of a vertical adjustment groove 111 and a horizontal positioning groove 112, is formed on the side wall of the housing 11. Protrusions are formed inward on both sides of the vertical adjustment groove 111, forming a limiting structure 6. A through hole is formed on the bottom surface of the housing 11 for the positioning rotating rod 12 to pass through. Multiple separate claws 113 extend downward around the through hole, forming a ring structure at the bottom of the through hole. The outer ends of the claws 113 form barbs; when the claws are in the through hole, the barbs can fix the side wall of the through hole. The positioning rotating rod 12 is located within the housing 11. A protruding stop block 121 is provided on the side wall of the positioning rotating rod 12, which is confined within the L-shaped groove and located below the limiting structure 3.
[0017] When the stop block 121 is in the horizontal positioning groove 112, the bottom of the positioning rod 12 penetrates the through hole and pushes against each claw 113, causing the claws 113 to be locked. At this time, the claws 113 cannot disengage from the through holes on the drive 2 and the electrical board 3, thus forming a lock. When the stop block 121 is lifted into the vertical adjustment groove 111, the bottom of the positioning rod 12 enters the housing 11, and the claws 113 are in an unlocked state where they can be retracted inward under force. This allows the claws to disengage from the through holes on the drive 2 and the electrical board 3, facilitating component replacement.
[0018] In addition, a first holding plate 4 is provided at the upper end of the positioning rotary rod 12 to facilitate the rotation and switching of the positioning rotary rod 12. Because the structure of the entire assembly is relatively small, a second holding plate 5 is provided on the side wall of the housing 11 for easy gripping.
[0019] In addition, a recessed groove is provided on the inner side of the housing 11, and a circumferential protrusion 122 is provided on the positioning rod 12. When the positioning rod is lifted in the vertical adjustment groove, the protrusion 122 is locked in the groove for positioning. When subjected to a downward force, the protrusion 122 can disengage from the groove and move downward.
[0020] The embodiments described above are for illustrative purposes only and are not intended to limit the scope of this utility model. All equivalent changes and modifications made to this utility model by those skilled in the art should fall within the scope of the appended claims.
