DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will further describe the specific implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0019] As Figures 1-4 shown, the present utility model is an installation and fixing device for an internal controller of an advertising light box, including a mounting plate 1. A groove 12 is provided inside the mounting plate 1. A rotating rod 13 is rotatably connected in the groove 12 through a bearing. The upper end of the rotating rod 13 is connected to a vertical plate 2. A trapezoidal block 21 is provided on one side of the vertical plate 2, and an inclined block 22 is provided on the other side of the vertical plate 2. When installing the controller of the advertising light box, the controller together with its external housing is placed on the mounting plate 1. Two first limit blocks 14 are provided at the upper end of the mounting plate 1. The bottom end of the controller housing 4 is slidably connected in the two first limit blocks 14. The bottom end of the controller housing 4 is snapped into the first limit blocks 14. The inclined block 22 is rotated counterclockwise. The controller housing 4 is placed at the lower end of the inclined block 22. At this time, the inclined block 22 is rotated clockwise, and the upper end of the controller housing 4 is snapped into the lower end of the inclined block 22. After the snapping is completed, the vertical plate 2 is in a vertical state at this time.

[0020] A chute 3 is opened on the mounting plate 1. A slide bar 31 is fixedly provided in the chute 3. A slider 33 is slidably connected to the slide bar 31. A slide plate 34 is provided at the upper end of the slider 33. A connecting rod 35 is provided on the slide plate 34. A positioning block 36 is provided on the connecting rod 35. During the installation process of the controller housing 4, the slide plate 34 is pulled outward. The slide plate 34 drives the lower slider 33 to slide on the slide bar 31. A spring 32 is sleeved outside the slide bar 31. One end of the spring 32 is connected to the side wall of the slider 33, and the other end is connected to the inner wall of the chute 3. During the movement of the slider 33, the spring 32 is compressed. When the upper end of the controller housing 4 is installed at the lower end of the inclined block 22, the slide plate 34 is released. The spring 32 needs to return to its original state. The spring 32 can push the slider 33 to move inward. The slider 33 drives the upper positioning block 36 to move horizontally. The positioning block 36 can be horizontally snapped onto the upper end of the horizontal trapezoidal block 21. At this time, the spring 32 is in a compressed state. The spring 32 can push the slider 33, so that the positioning block 36 is always snapped onto the upper end of the trapezoidal block 21, thereby preventing the vertical plate 2 from rotating, causing the inclined block 22 to disengage from the controller housing 4 and resulting in unstable installation. Furthermore, without using tools such as fixing bolts, the installation of the light box controller is completed, which is convenient for the later replacement and maintenance of the light box controller.

[0021] A controller housing 4 is provided on the mounting plate 1. Heat dissipation openings 43 and magnetic strips 45 are provided on both sides of the controller housing 4. Second limit blocks 44 are fixedly provided on both sides of the controller housing 4. A filter plate 46 is provided inside the second limit blocks 44. During the use of the controller, heat generated by the controller during operation needs to be dissipated through the heat dissipation openings 43. By providing the filter plate 46, it is possible to prevent external dust from entering the controller housing 4 and affecting the use environment of the controller. When the filter plate 46 needs to be replaced, a magnetic strip 45 is synchronously provided on the inner side of the filter plate 46. The magnetic strip 45 on the inner side of the filter plate 46 and the magnetic strip 45 on the side wall of the controller housing 4 are magnetically attracted. Pull the filter plate 46 outwards to separate the magnetic strip 45 on the filter plate 46 from the magnetic strip 45 of the controller housing 4, and pull the filter plate 46 out from the upper end of the second limit block 44, so as to facilitate the cleaning and replacement of the filter plate 46.

[0022] In the above solution, mounting holes 11 are provided at four places on the mounting plate 1. The mounting plate 1 is mounted at the required mounting position inside the advertising light box through fixing bolts and the mounting holes 11.

[0023] In the above solution, a protective pad 23 is provided inside the inclined block 22, and a handle 37 is provided on one side of the positioning block 36. By providing the protective pad 23, it is possible to prevent damage to the body of the controller housing 4 when the inclined block 22 limits the side of the controller housing 4. By providing the handle 37, it is convenient to pull the positioning block 36.

[0024] In the above solution, a dust-proof plate 41 is provided at the upper end of the controller housing 4, and a rubber dust-proof sleeve 42 is provided on the dust-proof plate 41. The rubber dust-proof sleeve 42 is arranged outside the buttons of the controller. The rubber dust-proof sleeve 42 can ensure the pressing use effect of the buttons and prevent external dust from entering through the gaps of the buttons, further playing a dust-proof effect on the inside of the controller.

[0025] Working principle:

[0026] When the installation and fixing device for the controller inside the advertising light box works specifically, open the advertising light box and install the mounting plate inside the advertising light box. First, pull the handle 37 outwards. The sliding plate 34 drives the slider 33 at the lower end to slide on the sliding rod 31. During the movement of the slider 33, the spring 32 is compressed. The bottom end of the controller housing 4 is engaged in the first limit block 14. Rotate the inclined block 22 counterclockwise, place the controller housing 4 at the lower end of the inclined block 22, and then rotate the inclined block 22 clockwise. At this time, release the handle 37. The spring 32 can push the slider 33, so that the positioning block 36 is always engaged at the upper end of the trapezoidal block 21, thereby preventing the vertical plate 2 from rotating. Without the premise of using tools such as fixing bolts, the installation of the light box controller is completed, which is convenient for the later replacement and maintenance of the light box controller.

[0027] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
