Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution:

the LED backlight source mounting and fixing mechanism comprises a mounting plate 1, wherein the outside of the mounting plate 1 is fixedly connected with two fixing rods 2, the two fixing rods 2 are symmetrically distributed, the outside of each fixing rod 2 is slidably connected with a limiting plate 3, a spring 4 is sleeved outside each fixing rod 2 and between the mounting plate 1 and the limiting plate 3, and the limiting plates 3 are driven to abut against LED backlight plates 8 mounted on the fixing rods 2 under the elastic force of the springs 4; one end of a spring 4 is fixedly connected with the mounting plate 1, the other end of the spring 4 is fixedly connected with the limiting plate 3, an accommodating groove 5 is formed in the fixing rod 2, a rotating plate 6 is rotatably connected in the accommodating groove 5, an elastic sheet 7 is fixedly connected between the rotating plate 6 and the accommodating groove 5, under the elastic force action of the elastic sheet 7, after the LED backlight plate 8 is mounted on the fixing rod 2, the rotating plate 6 in the accommodating groove 5 rotates out and is attached to the surface of the LED backlight plate 8, and the LED backlight plate 8 is fixed by matching with the abutting of the limiting plate 3; an LED backlight plate 8 is arranged outside the fixed rod 2 and between the limiting plate 3 and the rotating plate 6, a through hole 9 matched with the fixed rod 2 is formed in the LED backlight plate 8, and the through hole 9 formed in the LED backlight plate 8 is used for installing and connecting the LED backlight plate 8 and the fixed rod 2; the rubber gasket 10 is fixedly connected to the outer part of the rotating plate 6, the rubber gasket 10 on the rotating plate 6 can increase the friction force between the rotating plate 6 and the LED backlight plate 8 and improve the fastening performance on one hand, and is used for protecting the LED backlight plate 8 and preventing the rotating plate 6 from crushing the LED backlight plate 8 on the other hand; a limiting block 11 is fixedly connected inside the accommodating groove 5 and positioned at one side of the rotating plate 6, and due to the elastic force of the elastic sheet 7, after the LED backlight plate 8 is installed on the fixed rod 2, the rotating plate 6 in the accommodating groove 5 can automatically rotate out, and the rotating position angle of the rotating plate 6 is limited under the action of the limiting block 11, so that the rotating plate 6 is prevented from rotating out too much and cannot effectively abut against the LED backlight plate 8; mounting holes 12 are formed in the mounting plate 1, the number of the mounting holes 12 is four, the four mounting holes 12 are symmetrically distributed, and the mounting plate 1 is fixed through the mounting holes 12; the fixed rod 2 is of a square structure, and the fixed rod 2 of the square structure is beneficial to storage of the rotating plate 6.

Specifically, when the utility model is used, firstly, when the LED backlight board 8 needs to be disassembled, the LED backlight board 8 is pushed towards the direction close to the mounting plate 1 and the rotating plate 6 on the fixing rod 2 is pressed, so that the rotating plate 6 rotates to the containing groove 5, at the moment, under the elastic force action of the spring 4, the limiting plate 3 gives the LED backlight board 8 a tendency of reversely sliding towards the direction far away from the mounting plate 1, a worker pulls the LED backlight board 8 outwards to take off the LED backlight board, in the process, due to the elastic force of the spring 4, the limiting plate 3 on the fixing rod 2 can move to the position at one side of the rotating plate 6, so as to block the rotating plate 6, the rotating plate 6 can not rotate out from the containing groove 5, when the LED backlight board 8 needs to be installed, only the LED backlight board 8 needs to be installed on the fixing rod 2, so that the fixing rod 2 passes through the through hole 9 on the LED backlight board 8, in-process LED board 8 in a poor light will extrude limiting plate 3, make limiting plate 3 compress spring 4, move to the position that no longer blocks rotor plate 6 until limiting plate 3, LED board 8 in a poor light has also moved the position that is in rotor plate 6 top simultaneously, this moment under the elastic force of shell fragment 7, take in rotor plate 6 in groove 5 and roll out, loose the hand after, compressed spring 4 drives limiting plate 3 through elasticity and promotes LED board 8 in a poor light, make the surface of LED board 8 in a poor light opposite side and the laminating of rubber gasket 10 on the rotor plate 6, finally accomplish the installation to LED board 8 in a poor light, and easy operation is swift.
