[0006] Furthermore, a reinforcing piece is fixedly connected to the right side of the back plate, and the reinforcing piece is clamped at the bottom of the backlight strip.

[0007] Furthermore, a pull block is fixedly connected to the top of the lifting rod, and the lower surface of the pull block overlaps the top of the back plate.

[0008] Furthermore, the top clamp is designed to be L-shaped.

[0009] The present invention provides a positioning mechanism for an LED backlight strip, which has the following beneficial effects:

[0010] The positioning mechanism of the LED backlight strip fixes the middle part of the strip through the cooperation among the mounting groove, the fixing plate, the positioning groove and the clamping rod, further increases the firmness of the strip after installation through the setting of the reinforcement piece, fixes the upper part of the strip through the cooperation among the slot, the moving block, the lifting rod, the pulling block, the lifting hole, the spring and the top clamping piece, and the above structure is also very convenient when replacing the strip, which solves the problem that the common LED backlight strip is installed by gluing, and once the strip is damaged, it is not easy to replace.

DETAILED DESCRIPTION

[0015] like Figure 1-3 As shown, an embodiment of the present invention provides a positioning mechanism for an LED backlight strip, comprising a back plate 1, a backlight strip 2 is overlapped on the right side of the back plate 1, a reinforcing member is fixedly connected to the right side of the back plate 1, the reinforcing member is located at the bottom of the backlight strip 2 and clamped, a mounting groove 10 is provided on the right side of the back plate 1, a fixing plate 11 is clamped inside the mounting groove 10, the right side of the fixing plate 11 is fixedly connected to the left side of the backlight strip 2, a positioning groove 12 is provided on the inner bottom wall of the mounting groove 10, a clamping rod 13 is clamped inside the positioning groove 12, the top of the clamping rod 13 is fixedly connected to the lower surface of the fixing plate 11, a slot 3 is provided on the right side of the back plate 1, the inner side of the slot 3 The back plate 1 is movably connected with a moving block 4, and the right side of the moving block 4 is fixedly connected with a top clamp 9. The top clamp 9 is L-shaped and is clamped at the top of the backlight strip 2. A lifting hole 7 connected to the inside of the slot 3 is opened on the top of the back plate 1. A lifting rod 5 is movably connected inside the lifting hole 7. A pulling block 6 is fixedly connected to the top of the lifting rod 5. The lower surface of the pulling block 6 overlaps the top of the back plate 1, and the bottom end of the lifting rod 5 is fixedly connected to the upper surface of the moving block 4. A spring 8 is sleeved on the surface of the lifting rod 5, and the bottom end of the spring 8 is fixedly connected to the upper surface of the moving block 4, and the top of the spring 8 is fixedly connected to the inner top wall of the slot 3.

[0016] Working principle: During installation, pull the pull block 6 upward so that the top clamp 9 also moves upward, then place the backlight board 2 on the left side of the back panel 1 and contact it with the left side of the back panel 1. At the same time, the fixing plate 11 should be located inside the installation groove 10, then push the backlight board 2 downward so that the fixing plate 11 drives the clamping rod 13 to insert into the positioning groove 12. During the downward movement, the bottom of the backlight board 2 will be stuck in the reinforcement. Finally, release the pull block 6. At this time, the spring 8 releases the elastic force to push the moving block 4 downward. The moving block 4 will drive the top clamp 9 to be stuck on the top of the backlight board 2 for fastening. During disassembly, you only need to pull the pull block 6 upward to separate the top clamp 9 from the backlight board 2, then push the backlight board 2 upward, and finally take it to the right to complete.
