[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0024] Embodiment 1: As shown in the figure, the technical scheme adopted by the present application is as follows: a LED light bar fixing structure, comprising a light bar 1 and a fixing strip 8, the light bar 1 is limitingly installed inside the fixing strip 8, the side wall of the light bar 1 is fixedly connected with a heat conduction plate 3, and a plurality of limiting structures are arranged on the heat conduction plate 3. Figures 1-3

[0025] The two shafts 4 are limitingly rotatably installed on the heat conduction plate 3.

[0026] Specifically, the two ends of the shaft 4 and the heat conduction plate 3 are fixedly connected with torsional springs.

[0027] The two shafts 4 are fixedly connected with a connecting belt 6. In order to facilitate the finger to push the connecting belt 6, recesses 10 are arranged on the upper and lower sides of the opening of the fixing strip 8.

[0028] The upper and lower ends of the shaft 4 are fixedly connected with a clamping strip 5, and the end of the clamping strip 5 away from the shaft 4 is fixedly connected with a clamping hook 7.

[0029] A plurality of stop blocks 9 are fixedly installed on the inner bottom surface of the fixing strip 8, and the stop blocks 9 are slidingly matched with the corresponding clamping hooks 7.

[0030] In order to facilitate the sliding matching of the stop blocks 9 and the corresponding clamping hooks 7, the side of the stop block 9 corresponding to the clamping hook 7 is provided with a chamfer.

[0031] A spring rod 11 is fixedly installed on the inner wall of the fixing strip 8. The extension end of the spring rod 11 abuts against the heat conduction plate 3.

[0032] A plurality of lamp beads 2 are fixedly installed on the side of the light bar 1 away from the heat conduction plate 3.

[0033] Working principle:

[0034] ​In use, first install the fixing strip 8 to the location where the light fixture needs to be installed. Then align the retaining strip 5 on the light strip 1 with the corresponding stop block 9, and push the light strip 1 into the fixing strip 8. The inclined surface at the front end of the hook 7 contacts the arc surface on the stop block 9, and is pushed outward by the arc surface during the pushing process, causing the retaining strip 5 to rotate outward around the pivot 4. As the light strip 1 is continued to be pushed, the hook 7 passes the stop block 9, and under the action of the torsion spring on the pivot 4, the retaining strip 5 rotates in the opposite direction, thereby making the hook 7 engage with the rear side of the stop block 9.

[0035] At the same time, the heat-conducting plate 3 behind the light strip 1 contacts the spring rod 11 and compresses the spring rod 11 during the inward movement. When the hook 7 is engaged with the back of the light panel, the pushing force on the light strip 1 is released, causing the spring rod 11 to push the light strip 1 outward from the fixing strip 8. The hook 7 is blocked by the baffle and cannot move outward, thus making the light strip 1 stably fixed inside the fixing strip 8.

[0036] The large distance between the installed LED strip 1 and the rear side wall of the fixing strip 8 helps the heat-conducting plate 3 dissipate heat, thereby preventing the LED bead 2 from overheating and enabling the LED bead 2 to work stably.

[0037] When it is necessary to replace or repair the light strip 1, simply push the connecting strip 6 inward with two fingers and pinch the light strip 1. Pushing the connecting strip 6 will cause the middle part of the connecting strip 6 to move inward. The two ends of the connecting strip 6 will pull the rotating shaft 4 to rotate, and at the same time the light strip 1 will move inward, so that the hook 7 can easily open. Then, pull the light strip 1 outward to remove the light strip 1. The connecting strip 6 of this structure is located in the groove 10, which is convenient for finger operation and provides great convenience for the replacement and repair of the light strip 1.

[0038] Example 2: Figure 4 As shown, the difference between this embodiment and embodiment 1 is that: multiple strip-shaped holes are evenly opened on the side wall of the fixing strip 8; heat sinks 13 are slidably installed inside the strip-shaped holes, and a copper plate 12 is fixedly installed on one end of the heat sink 13 inside the fixing strip 8; the copper plate 12 is fixedly connected to the telescopic end of the spring rod 11.

[0039] Working principle:

[0040] In this embodiment, the fixing and disassembly of the light strip 1 are exactly the same as in Embodiment 1. The difference is that when the light strip 1 is installed in the fixing strip 8, the heat-conducting plate 3 is in close contact with the copper plate 12, and the copper plate 12 squeezes the spring rod 11, so that the heat sink 13 on the copper plate 12 extends out of the fixing strip 8 through the strip hole, which further improves the heat dissipation of the light strip 1, making the light strip 1 work stably and helping to extend the life of the light strip 1.

[0041] And every time the disassembly or replacement of the light bar 1, the spring rod 11 recovery process will drive the heat sink 13 to move to the fixed strip 8, so that the dust on the heat sink 13 is removed by the side wall of the strip-shaped hole, so that the heat sink 13 can maintain good heat dissipation performance. And the heat sink 13 is kept in the fixed strip 8 without installing the light bar 1, avoiding damage to the heat sink 13 during transportation and installation.

[0042] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
