Figure 3 As shown, one end of the first mounting sleeve 1 is conveniently inserted into the first mounting sleeve 1;

[0024] A locking component 5 for locking the backlight source 3 and the screen control panel 4 is provided at the connection between the first mounting sleeve 1 and the second mounting sleeve 2;

[0025] Specifically, the locking assembly 5 includes a control rod 501, which is disposed in the inner cavity of the second mounting sleeve 2, and a movable column 502 is fixedly connected to the end of the control rod 501, and a locking block 503 is inserted and connected to the side of the movable column 502, and the side of the locking block 503 is inserted and connected to the insertion of the first mounting sleeve 1 and the second mounting sleeve 2;

[0026] It should be noted that the cross-sectional radius of the control rod 501 is smaller than the cross-sectional radius of the moving column 502, and the cross-sectional radius of the moving column 502 is 1.1 times the cross-sectional radius of the control rod 501, and a reset groove 5021 for the locking block 503 to be inserted is provided on the side of the moving column 502, a locking ring groove 101 for the locking block 503 to be inserted is provided on the inner wall of the first installation sleeve 1, and a through hole for the locking block 503 to be inserted is provided on the inner wall of the second installation sleeve 2;

[0027] Specifically, the inner wall of the reset groove 5021 is provided with an extrusion protrusion 5022 for extruding the locking block 503, and the inner wall of the locking ring groove 101 is arranged in an inclined shape. The extrusion protrusion 5022 facilitates the extrusion movement of the locking block 503, so that it protrudes from the through hole and enters the locking ring groove 101, thereby locking the interlaced portion of the first installation sleeve 1 and the second installation sleeve 2. The inclined shape facilitates the locking block 503 to be extruded from the locking ring groove 101;

[0028] The outer side of the control rod 501 is provided with a rebound portion for pushing the moving column 502 to return to its original position;

[0029] Specifically, the rebound part includes a fixing ring 504 and a compression spring 505 sleeved on the outside of the control rod 501, and the inner wall of the second mounting sleeve 2 is provided with a deformation groove 201 for the fixing ring 504 and the compression spring 505 to move;

[0030] It should be noted that the cross-sectional radius of the deformation groove 201 is larger than the cross-sectional radius of the inner cavity of the second installation sleeve 2, and the compression spring 505 and the fixing ring 504 are both arranged inside the deformation groove 201, the middle part of the fixing ring 504 is fixed to the outer side of the control rod 501 by glue, and the fixing ring 504 is arranged at the end of the compression spring 505 away from the moving column 502, the cross-sectional radius of the compression spring 505 is larger than the cross-sectional radius of the inner cavity of the second installation sleeve 2, and the cross-sectional radius of the fixing ring 504 is larger than the cross-sectional radius of the compression spring 505, so that it can squeeze the compression spring 505;

[0031] In actual use, the second installation sleeve 2 connected to the screen control panel 4 is installed and inserted into the first installation sleeve 1 connected to the backlight light source 3, and the control rod 501 is pressed at the same time, so that the control rod 501 drives the moving column 502 to move downward, and the locking block 503 retracts into the positioning groove 5021. After the insertion is completed, all the control rods 501 are released, and the compression spring 505 drives the fixing ring 504 to move, thereby squeezing the protrusion 5022 to squeeze the locking block 503 from the through hole into the locking ring groove 101. When inspecting, repairing and disassembling, all the control rods 501 can be pressed and pasted with adhesive tape so that the control rods 501 moves down, the reset groove 5021 moves, the extrusion protrusion 5022 moves, and the locking block 503 cannot be squeezed. At this time, the screen control panel 4 is pulled to drive the second mounting sleeve 2 to separate from the first mounting sleeve 1, and the inner wall of the locking ring groove 101 squeezes the outer side of the locking block 503, so that the locking block 503 is separated from the locking ring groove 101, and the backlight light source 3 and the screen control panel 4 are disassembled from each other. Compared with the backlight light source 3 directly being fixed to the screen control panel 4 with multiple screws, this fixing form is convenient for the staff to quickly disassemble, inspect and install the two when performing screen inspection and screen control panel 4 maintenance.
