[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 The utility model provides a new technical solution: a convenient assembly type backlight source, comprising a backlight panel 1, a backlight source mounting frame 2 is provided on the lower surface of the backlight panel 1, positioning grooves 3 are provided on the vertical plates of the backlight source mounting frame, and eight positioning blocks 4 are fixedly installed in the inner walls of the four positioning grooves 3;

[0028] Among them, an installation mechanism is provided on the backlight source mounting frame 2, and the installation mechanism includes four slots 5, four fixing columns 6, four card holes 7, four spring slots 8, four sliding holes 9, four sliding slots 10, four fixing rods 11, four card blocks 12, four springs 13 and four fixing plates 14.

[0029] Furthermore, four slots 5 are all provided on the upper surface of the backlight installation frame 2 , and four spring slots 8 are respectively provided in the inner walls of the four slots 5 .

[0030] Furthermore, four sliding holes 9 are respectively opened in the inner walls of the four spring slots 8 , and four sliding grooves 10 are respectively opened on the outer surface of the backlight mounting frame 2 . The four sliding grooves 10 are respectively communicated with the four sliding holes 9 .

[0031] Furthermore, the four fixing rods 11 are respectively slidably sleeved in the inner walls of the four sliding holes 9, and the four clamping blocks 12 are respectively fixedly installed on the opposite ends of the four fixing rods 11, and the upper surfaces of the four clamping blocks 12 are all inclined.

[0032] Furthermore, four springs 13 are fixedly mounted on opposite surfaces of the four clamping blocks 12, and opposite ends of the four springs 13 are fixedly mounted on inner walls of the four spring slots 8.

[0033] The four fixing plates 14 are fixedly sleeved on the outer surfaces of the four fixing rods 11 , and the four fixing plates 14 are slidably sleeved on the inner walls of the four sliding grooves 10 .

[0034] Furthermore, the four fixing posts 6 are fixedly mounted on the lower surface of the backlight panel 1, and the four latching holes 7 are respectively opened on the outer surfaces of the four fixing posts 6;

[0035] When using this convenient assembled backlight source, the constituent diaphragms of the backlight source are placed into the backlight source mounting frame 2 in sequence, and the various diaphragms are limited by the positioning grooves 3, and the diaphragms are positioned by the positioning blocks 4 provided in the positioning grooves 3 to ensure that they are installed accurately and will not deviate. At this time, the four fixing columns 6 fixedly installed on the lower surface of the backlight panel 1 are correspondingly inserted into the four slots 5 opened on the upper surface of the backlight source mounting frame 2. At this time, the four fixing columns 6 hit the inclined surface of the card block 12 and apply a rightward thrust to the card block 12 to make it move to the right. At the same time, the card block 12 applies pressure to the spring 13 fixedly installed on the right surface to make it contract. At this time, the fixing column 6 is continued to be inserted into the four slots opened on the rear surface of the backlight source mounting frame 2. When the locking plate 12 is moved to the left, it is locked into the locking hole 7 on the outer surface of the fixing column 6 for fixing. When the locking plate 12 is removed, the fixing plate 14 is moved to the right on the inner surface of the slide groove 10. At the same time, the fixing plate 14 drives the fixing rod 11 fixed on the inner surface to move to the right. The fixing rod 11 drives the fixing block 12 fixed on the left end to disengage from the locking hole 7 on the outer surface of the fixing column 6, and the disassembly of the backlight panel 1 is completed.

[0036] The convenient assembly type backlight source connects the backlight panel 1 and the backlight source mounting frame 2 by snapping together. No additional tools are required during installation, and the installation speed is fast. The overall installation of the backlight source is easy to complete, which is more convenient. In addition, the convenient assembly type backlight source has positioning grooves 3 provided on the backlight source mounting frame 2, and various diaphragms are limited by the positioning grooves 3 and the positioning blocks 4 provided in the positioning grooves 3 are used to position the diaphragms, thereby ensuring that the installation is accurate and will not deviate, thereby improving the overall installation quality.

[0037] Working principle: When the convenient assembled backlight source is used, the constituent diaphragms of the backlight source are placed into the backlight source mounting frame 2 in sequence, and the various diaphragms are limited by the positioning grooves 3, and the diaphragms are positioned by the positioning blocks 4 provided in the positioning grooves 3 to ensure that they are installed accurately and will not deviate. At this time, the four fixing columns 6 fixedly installed on the lower surface of the backlight panel 1 are correspondingly inserted into the four slots 5 opened on the upper surface of the backlight source mounting frame 2. At this time, the four fixing columns 6 hit the inclined surface of the card block 12 and apply a rightward thrust to the card block 12 to move it to the right. At the same time, the card block 12 applies pressure to the spring 13 fixedly installed on the right surface to cause it to shrink. At this time, the fixing columns 6 are continued to be inserted into the opening on the rear surface of the backlight source mounting frame 2. Assume that the four slots 5 are deep, at this time the card block 12 passes through the card hole 7 opened on the outer surface of the fixing column 6, at this time the card block 12 is no longer subjected to the extrusion force applied by the fixing column 6, and the spring 13 is no longer under force. At this time, the spring 13 expands, and the spring 13 applies a leftward thrust to the card block 12 fixedly installed at the left end, causing it to move to the left. At this time, the card block 12 moves to the left and is connected to the card hole 7 opened on the outer surface of the fixing column 6 for fixing. When it is disassembled, the fixing plate 14 is to be toggled to slide to the right on the inner surface of the slide groove 10. At the same time, the fixing plate 14 drives the fixing rod 11 fixed on the inner surface to move to the right, and the fixing rod 11 drives the card block 12 fixedly installed on the left end to disengage from the card hole 7 opened on the outer surface of the fixing column 6, thereby completing the disassembly of the backlight panel 1.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
