Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

The utility model discloses an LED display device convenient to maintain, which is shown in fig. 1 and 2, and comprises a mounting bracket 1, a plurality of displays 2 arranged in the mounting bracket 1 and a plurality of control units 3 for controlling the operation of the displays 2. The mounting bracket 1 comprises a fixing frame 11 and a mounting frame 12 arranged around the fixing frame 11, the fixing frame 11 is arranged in an inner cavity of the mounting frame 12 and is fixed with the mounting frame 12 by bolts, the side wall of the fixing frame 11, which is close to the display 2, can be flush with the side wall of the mounting frame 12, which is close to the display 2, and the display 2 is fixed on the mounting frame 12 and the fixing frame 11 by bolts. The end face of the fixing frame 11 far away from the display 2 is provided with a mounting box 4, the mounting box 4 comprises a shell 41 with an opening at one side and a cover 42 capable of opening and closing the opening of the shell 41, and the control unit 3 is fixed in the shell 41 by using bolts and is electrically connected with the display 2. The casing 41 is fixed on the side wall of the fixing frame 11 far away from the display 2 by using bolts, the casing 41 is vertically arranged, an opening of the casing 41 is positioned on one side far away from the fixing frame 11, and the cover 42 is rotatably connected to the casing 41. The side wall of the shell 41, which is close to the display 2, is also provided with a plurality of sockets 43 electrically connected with the control unit 3, and the sockets 43 can be connected with plugs on the display 2 so as to realize the connection of the display 2 and the control unit 3.

As shown in fig. 3 and 4, the casing 41 is further provided with a locking mechanism 5 for restricting the opening of the cover 42, the locking mechanism 5 includes a fixed hook 51 fixed to the cover 42 by a bolt, a rotating member 52 rotatably connected to the casing 41, and a movable hook 53 capable of hooking to the fixed hook 51, and one end of the movable hook 53 away from the fixed hook 51 is rotatably connected to the rotating member 52. The rotation axes of the movable hook 53 and the rotary member 52 can be moved to a side of the rotary member 52 away from the fixed hook 51 with respect to the rotation axis of the housing 41, so that after the fixed hook 51 and the movable hook 53 are hooked, the position of the rotary member 52 can be kept limited so that the fixed hook 51 and the movable hook 53 include the hooking, making the closing of the cover 42 less susceptible.

As shown in fig. 2, since the plurality of mounting brackets 1 are also required to be spliced during use of the display 2 to form a display having a larger area, the control units 3 in the plurality of housings 41 are required to be connected to each other. Therefore, the lower end of the housing 41 is provided with a plurality of control lines 44 electrically connected to the control unit 3, and the control lines 44 extend along the inner wall of the nearest mounting frame 12 so as to be connected to the control lines 44 on the adjacent mounting brackets 1.

As shown in fig. 2 and 3, in order to prevent the control line 44 from being collided during installation and use, the inner wall of the installation frame 12, which is close to the control line 44, is provided with a receiving groove 121, and the control line 44 can be disposed in the receiving groove 121 and arranged along the length direction of the receiving groove 121. The mounting frame 12 is further provided with a cover plate 13 capable of opening and closing the opening of the accommodating groove 121, the cover plate 13 is rotatably connected to the mounting frame 12, and the rotation axes of the mounting frame 12 and the cover plate 13 are located at one side far away from the display 2. The upper end of the cover plate 13 is penetrated with a relief groove 131, the relief groove 131 penetrates the cover plate 13 close to the side wall of the display 2, and the control circuit 44 can penetrate through the relief groove 131 and enter the accommodating groove 121. In the process of opening the cover plate 13, the giving-up groove 131 can prevent the rotating cover plate 13 from contacting with the control circuit 44, so that the cover plate 13 is more convenient to open. The control circuit 44 can be directly overhauled and replaced after the cover plate 13 is opened, so that the overhauling process of the control circuit 44 is more convenient.

In order that the cover 13 can stably close the opening of the receiving groove 121 during the process that the cover 13 is not opened, the mounting frame 12 is also provided with a locking mechanism 5 defining the position of the cover 13, the fixing hook 51 of the locking mechanism 5 is fixed to the mounting frame 12 using a bolt, and the rotating member 52 thereof is provided on the cover 13. Therefore, the position of the cover plate 13 is limited by the locking mechanism 5, and when the cover plate 13 needs to be opened to repair the control circuit 44, the rotating piece 52 can be conveniently rotated, so that the fixed hooks 51 and the movable hooks 53 do not limit the rotation of the cover plate 13 relative to the mounting frame 12 any more, and the control circuit 44 is more convenient to repair and replace.

Due to the clearance between the housing 41 and the cover 13, the control line 44 is led out of the housing 41 and is still partially exposed before entering the receiving groove 121, and the exposed control line 44 is vulnerable to damage. Therefore, the end of the cover body 42 close to the cover plate 13 is integrally formed with the extension portion 421, and the end of the extension portion 421 away from the cover body 42 can leave a gap with the side wall of the cover plate 13 close to the housing 41, and the control circuit 44 is disposed between the extension portion 421 and the display 2, so that the control circuit 44 is protected by the extension portion 421, so that the control circuit 44 is not directly exposed, and the control circuit 44 is not easily damaged by the outside. The relief groove 131 extends below the extension portion 421, so that the extension portion 421 can be located in the relief groove 131 during the rotation of the cover 13, and the extension portion 421 does not affect the rotation of the cover 13.

The implementation principle of the embodiment is as follows: when maintenance of the control unit 3 or the like is required, the cover 42 can be opened easily by rotating the rotating member 52 connected to the housing 41 to disengage the fixed hooks 51 and the movable hooks 53 on the housing 41 and the cover 42. When the cover 13 needs to be opened, the rotating piece 52 arranged on the cover 13 is rotated to separate the cover 13 from the fixed hook 51 and the movable hook 53 on the mounting frame 12, so that the cover 13 is opened, and the control circuit 44 is convenient to overhaul.

The embodiments of the present utility model are all preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model in this way, therefore: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
