Description

Technical Field

[0001] This utility model relates to the field of die-cast aluminum enclosure technology, and in particular to a die-cast aluminum enclosure for an LED stadium screen. Background Technology

[0002] LED stadium screen die-cast aluminum enclosures are specialized housings and frames for LED displays, primarily used in stadiums, sports fields, and various large outdoor or indoor courts to protect and support the displays. Made of die-cast aluminum, these enclosures are lightweight, sturdy, corrosion-resistant, and offer excellent heat dissipation, ensuring stable long-term operation of the LED displays. Typically, LED stadium screen die-cast aluminum enclosures are installed on the front or back walls, side walls, or pillars of the stadium, as well as the edge areas around the field. However, due to the highly unpredictable trajectory of the ball during a match, especially during intense competition or tackling, the ball is likely to collide with these enclosures.

[0003] Existing LED stadium screen die-cast aluminum cabinets mostly use a slot fixing method for their support structure. One end of the bracket is inserted into a groove reserved on the fixing plate to fix the position of the cabinet, while the other end of the bracket supports the LED cabinet. Although this design is convenient for installation and maintenance, when the LED cabinet is impacted and shakes, the bracket may disengage from the groove, causing the LED cabinet to lose support and collapse.

[0004] Therefore, those skilled in the art have provided a die-cast aluminum housing for LED stadium screens to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a die-cast aluminum housing for an LED stadium screen. By moving the handle, the positioning column is disengaged from the positioning hole, and the spring force enables rapid adjustment and fixation of the support plate angle, thereby enhancing the stability of the structure, effectively preventing loosening caused by vibration or external force, and improving the safety of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a die-cast aluminum housing for an LED stadium screen, comprising a die-cast aluminum main body housing and a fixing mechanism, wherein a long plate is fixedly connected to the middle of the rear end of the die-cast aluminum main body housing, and the front end of the fixing mechanism is connected to the rear end of the long plate;

[0007] The fixing mechanism includes a support plate and a fixing plate. A fixing block is fixedly connected to the rear end of the support plate. A movable block is movably arranged at the center of the fixing block. Springs are fixedly connected to both sides of the movable block. Positioning posts are fixedly connected to the opposite sides of the two springs. Handles are fixedly arranged at the upper ends of the two positioning posts. Two adjustment grooves are opened at the rear end of the fixing block. Multiple positioning holes are opened on both sides of the fixing plate near the rear end.

[0008] Furthermore, the two handles are respectively movably disposed in the two adjustment slots, and the two positioning pins are respectively movably disposed in the multiple positioning holes opened on both sides of the fixed plate near the rear end.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 3 One embodiment of this utility model is a die-cast aluminum housing for an LED stadium screen, comprising a die-cast aluminum main body housing 1 and a fixing mechanism 2. A long plate 3 is fixedly connected to the middle of the rear end of the die-cast aluminum main body housing 1, and the front end of the fixing mechanism 2 is connected to the rear end of the long plate 3.

[0026] Specifically, the die-cast aluminum main body box 1 is a common type of box in the prior art, while the long plate 3 is fixed to the rear end of the box by bolts.

[0027] Reference Figures 2-6The fixing mechanism 2 includes a support plate 201 and a fixing plate 208. A fixing block 202 is fixedly connected to the rear end of the support plate 201. A movable block 203 is movably arranged at the center of the fixing block 202. Springs 204 are fixedly connected to both sides of the movable block 203. Positioning pins 205 are fixedly connected to the opposite sides of the two springs 204. Handles 207 are fixedly arranged at the upper ends of the two positioning pins 205. Two adjustment grooves 206 are opened at the rear end of the fixing block 202. Multiple positioning holes 209 are opened on both sides of the fixing plate 208 near the rear end. The two handles 207 are movably arranged in the two adjustment grooves 206 respectively. The two positioning pins 205 are movably arranged in the multiple positioning holes 209 opened on both sides of the fixing plate 208 near the rear end. Holes 4 are opened on the upper ends of the inner walls on both sides of the long plate 3.

[0028] Specifically, the adjustment groove 206 is designed in a horizontal U-shape. When the user squeezes the handle 207 towards the center, the handle 207 moves along the upper end of the adjustment groove 206, compressing the spring 204. Since the spring 204 is fixedly connected to the movable block 203, and the movable block 203 is movably positioned inside the fixed block 202, the user can rotate the handle 207 downwards. When the handle 207 moves to the middle of the adjustment groove 206, the spring force of the spring 204 will press it against the groove wall, thus releasing the fixation on the support plate 201. Then, when the handle 207 is held in the middle of the adjustment groove 206, the user rotates the support plate 201 upwards until it fits against the inside of the long plate 3. Finally, the user rotates the handle 207 downwards, moving it into the adjustment groove. The spring 204 pushes the positioning post 205 into the hole 4 in the groove at the lower end of 206, thus completing the storage of the support plate 201. Secondly, the size of the positioning hole 209 and the hole 4 are matched with the size of the positioning post 205 to ensure that the positioning post 205 can be inserted and fixed. There are multiple positioning holes 209 on both sides of the rear end of the fixing plate 208. Through these positioning holes 209, the user can adjust the support of the support plate 201 at different angles. In addition, when the spring 204 pushes the positioning post 205, the handle 207 set at the upper end of the positioning post 205 moves in the adjustment groove 206. When the handle 207 moves to the maximum distance in the adjustment groove 206, it will be blocked by the adjustment groove 206 to prevent the spring 204 from popping the positioning post 205 out of the fixing block 202.

[0029] Reference Figures 2-6 The support plate 201 has two round shafts 2011 fixedly installed at the front ends of both sides. The two round shafts 2011 are respectively rotatably installed in the middle of the inner wall of both sides of the long plate 3. The front end of the fixing plate 208 is hinged to the lower end of the long plate 3. The fixing plate 208 has grooves 2010 in the middle of both sides.

[0030] Specifically, when the user stores the fixing plate 208, the support plate 201 needs to be stored first. Then, the fixing plate 208 is rotated upward with the hinge point of the fixing plate 208 as support. The grooves 2010 on both sides of the fixing plate 208 are respectively locked onto the two round shafts 2011. The fixing plate 208 has a U-shaped body. This shape can cover the support plate 201 during storage without being interfered with by it, thus completing the storage. In addition, the user can make threaded holes on the fixing plate 208 and then fix it to the ground with bolts.

[0031] Working principle: The user grasps the handle 207 and squeezes it towards the center, causing the positioning pin 205 to move along the adjustment groove 206 and disengage from the positioning hole 209. At the same time, the spring 204 is compressed. Then, the user rotates the handle 207 downward to the middle of the adjustment groove 206, where it is fixed by the elastic force of the spring 204. Next, the user moves the fixing block 202 to adjust the support angle of the support plate 201. After the support angle is adjusted, the user grasps the handle 207 again and rotates it upward to move the handle 207 to the upper end of the adjustment groove 206. Then, the elastic force of the spring 204 pushes the positioning pin 205 into the positioning hole 209, thereby fixing the support angle of the support plate 201.

[0032] Next, the user grips the handle 207 towards the center and rotates it downwards to the middle of the adjustment groove 206 to release the fixation. Then, using the round shaft 2011 as a support point, the user rotates the support plate 201 upwards to the upper end of the long plate 3. Next, the user rotates the handle 207 downwards to the lower end of the adjustment groove 206. Then, the positioning post 205 is pushed into the hole 4 by the elastic force of the spring 204, thus completing the storage of the support plate 201. Then, the user rotates the fixing plate 208 upwards to move it to the lower end of the long plate 3, and the groove 2010 will be locked on the round shaft 2011, completing the storage of the fixing plate 208.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
