Description

Technical Field

[0001] This utility model relates to the field of lighting installation accessories, and in particular to a lighting pressure plate with an anti-loosening structure. Background Technology

[0002] During the assembly and installation of lighting fixtures, the pressure plate is a key component used to fix the internal parts of the fixtures, and its connection stability directly affects the overall structural strength and safety of the fixtures.

[0003] Currently, most lighting fixture clamps on the market use a single bolt for fixing or a snap-fit ​​connection. When using bolts, over long-term use, factors such as slight vibrations during light fixture operation and changes in ambient temperature can cause the bolts to loosen, leading to a decrease in the clamp's fixing effect and even causing internal components to shift, affecting the normal operation of the light fixture. Furthermore, bolt installation requires precise alignment of the bolt holes, making the process cumbersome, especially in the confined space inside the light fixture, resulting in low installation efficiency. While snap-fit ​​connections are convenient to install, the elastic fatigue of the snaps is a significant issue; under prolonged stress, they are prone to deformation, leading to connection failure and also posing a risk of loosening. In addition, some clamps lack effective guiding and positioning structures, making it easy for them to shift during installation, making it difficult to ensure uniform clamping of internal components and potentially causing excessive localized stress and damage to these components.

[0004] To address the problems of loosening, inconvenient installation, and low positioning accuracy of existing lighting fixture clamps, this invention proposes a lighting fixture clamp with an anti-loosening structure, aiming to improve the stability of the clamp connection, simplify the installation operation, and ensure the long-term reliable operation of the lighting fixture. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this utility model provides a lighting fixture pressure plate with an anti-loosening structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A lighting fixture pressure plate with an anti-loosening structure includes a mounting base and a detachable pressure plate disposed inside the lighting fixture. A vertical guide assembly is disposed between the mounting base and the detachable pressure plate. Two transverse guide groove structures are symmetrically arranged on the left and right sides of the detachable pressure plate. A threaded adjustment slider assembly is disposed on the mounting base outside the transverse guide groove structure. The threaded adjustment slider assembly can be installed in a corresponding transverse guide groove structure and move left and right. An oblique pressing structure is disposed between the threaded adjustment slider assembly and the transverse guide groove structure.

[0008] As described above, a lighting fixture pressure plate with an anti-loosening structure includes a vertical guide assembly comprising a plurality of vertical guide holes disposed on the detachable pressure plate, and a plurality of vertical guide shafts disposed on the mounting base, wherein the vertical guide shafts pass through a corresponding vertical guide hole to position the detachable pressure plate.

[0009] As described above, a lighting fixture pressure plate with an anti-loosening structure is provided, wherein the detachable pressure plate includes a clamping connector, and the clamping connector is provided with a clamping part.

[0010] As described above, a lighting fixture pressure plate with an anti-loosening structure includes a transverse guide groove structure comprising a transverse boss disposed on the pressing connector, wherein a transverse groove is disposed within the transverse boss.

[0011] As described above, a lighting fixture pressure plate with an anti-loosening structure includes a threaded adjusting slider assembly comprising a screw hole seat disposed on one side of the mounting base, the screw hole seat having a transverse screw hole, a locking screw being threadedly connected to the transverse screw hole, and a rectangular slider being rotatably connected to the inner end of the locking screw. The rectangular slider can be installed in the transverse groove and move laterally, and the rotational movement of the rectangular slider is restricted by the cooperation between the inner wall of the transverse groove and the outer wall of the rectangular slider.

[0012] As described above, a lighting fixture pressure plate with an anti-loosening structure includes an arc-shaped pressing part disposed at the bottom of the rectangular slider, and an inclined guide surface disposed on the lower surface of the transverse groove. The rectangular slider can enter the transverse groove and move laterally, and gradually press down on the inclined guide surface through the arc-shaped pressing part.

[0013] The beneficial effects of this utility model are:

[0014] 1. By cooperating with the threaded adjustment slider assembly and the inclined pressure structure, a dual anti-loosening mechanism is formed using the self-locking property of the threaded connection and the pressure decomposition effect of the inclined guide surface. Even under long-term vibration or temperature change environments of the lighting fixture, the locking screw is not prone to loosening, and the continuous compression of the inclined guide surface by the arc-shaped downward pressing part can maintain the pressed state of the detachable pressure plate; the pressing force is controllable.

[0015] 2. By controlling the number of rotations of the locking screw, the moving distance of the rectangular slider can be precisely adjusted, thereby controlling the squeezing force of the arc-shaped pressing part on the inclined guide surface. This allows for flexible adjustment of the clamping force of the detachable pressure plate, suitable for fixing internal components of lamps of different materials and thicknesses, and avoids affecting the performance of components due to excessive or insufficient clamping force.

A threaded adjustment slider assembly 5 is disposed on the mounting base 1 outside the transverse guide groove structure 4. The threaded adjustment slider assembly 5 can be installed in a corresponding transverse guide groove structure 4 and move left and right. An inclined pressure structure 6 is disposed between the threaded adjustment slider assembly 5 and the transverse guide groove structure 4.

[0022] Installation and positioning: Align the vertical guide hole 301 of the removable pressure plate 2 with the vertical guide shaft 302 of the mounting base 1 and insert it, and position it through the vertical guide assembly 3; at this time, the horizontal groove 402 of the horizontal guide groove structure 4 is aligned with the rectangular slider 504 of the threaded adjustment slider assembly 5, and the rectangular slider 504 enters the horizontal groove 402.

[0023] Tightening and anti-loosening: Rotating the locking screw 503, because it is threadedly connected to the transverse screw hole 502 of the screw hole seat 501, and the rectangular slider 504 is restricted from rotating by the transverse groove 402, the rectangular slider 504 moves along the transverse groove 402; its bottom arc-shaped pressing part 601 presses the inclined guide surface 602 of the transverse groove 402, decomposes the downward pressure, pushes the detachable pressure plate 2 to move down along the vertical guide shaft 302, so that the pressing part 202 presses the parts, and the thread self-locking and inclined pressure form an anti-loosening mechanism.

[0024] Disassembly: Rotate the locking screw 503 in the opposite direction, the rectangular slider 504 moves outward, and the arc-shaped pressing part 601 disengages from the inclined guide surface 602; lift the detachable pressure plate 2 upward, and the vertical guide hole 301 disengages from the vertical guide shaft 302, completing the disassembly.

[0025] The vertical guide assembly 3 of this utility model includes a plurality of vertical guide holes 301 disposed on the detachable pressure plate 2, and a plurality of vertical guide shafts 302 disposed on the mounting base 1. The vertical guide shafts 302 pass through a corresponding vertical guide hole 301 to position the detachable pressure plate 2.

[0026] The detachable pressure plate 2 of this utility model includes a pressing connector 201, and a pressing part 202 is provided on the pressing connector 201.

[0027] The transverse guide groove structure 4 of this utility model includes a transverse boss 401 disposed on the pressing connector 201, and a transverse groove 402 is disposed in the transverse boss 401.

[0028] The threaded adjustment slider assembly 5 of this utility model includes a screw hole seat 501 disposed on one side of the mounting base 1, a transverse screw hole 502 disposed on the screw hole seat 501, a locking screw 503 internally threaded into the transverse screw hole 502, and a rectangular slider 504. The rectangular slider 504 is rotatably connected to the inner end of the locking screw 503. The rectangular slider 504 can be installed in the transverse groove 402 and move laterally. The rotational movement of the rectangular slider 504 is restricted by the cooperation between the inner wall of the transverse groove 402 and the outer wall of the rectangular slider 504.

[0029] The inclined pressing structure 6 of this utility model includes an arc-shaped pressing part 601 disposed at the bottom of the rectangular slider 504, and an inclined guide surface 602 disposed on the lower surface of the transverse groove 402. The rectangular slider 504 can enter the transverse groove 402 for transverse movement and gradually press down the inclined guide surface 602 through the arc-shaped pressing part 601.

[0030] In summary, the embodiments of this application utilize the cooperation between the threaded adjustment slider assembly and the inclined pressure structure, leveraging the self-locking property of the threaded connection and the pressure decomposition effect of the inclined guide surface to form a dual anti-loosening mechanism. Even under long-term vibration or temperature changes in the lighting fixture, the locking screw is unlikely to loosen, and the continuous compression of the inclined guide surface by the arc-shaped pressing part maintains the clamping state of the detachable pressure plate. The clamping force is controllable; by controlling the number of rotations of the locking screw, the movement distance of the rectangular slider can be precisely adjusted, thereby controlling the pressing force of the arc-shaped pressing part on the inclined guide surface. This allows for flexible adjustment of the clamping force of the detachable pressure plate, suitable for fixing internal components of lighting fixtures of different materials and thicknesses, avoiding the impact on component performance due to excessive or insufficient clamping force.
