Description

Technical Field

[0001] The utility model relates to the technical field of outdoor display manufacturing, in particular to an outdoor small-pitch heavy-duty LED display cabinet housing. Background Art

[0002] The LED display cabinet is a component for assembling an LED display. After the LED display is assembled into the cabinet, it is generally placed outdoors for publicity or display and is widely used in shopping malls and squares. For example, Chinese Patent CN201921426380.X discloses an LED display cabinet, which includes a cabinet body, a panel arranged on the cabinet body, and a door panel fixedly arranged on the rear part of the cabinet body. A plurality of reinforcing ribs are arranged on the back of the panel. Among them, a plurality of convex points are arranged on the upper surface of the reinforcing rib, and a plurality of convex points are arranged on the panel. The connection between the reinforcing rib and the panel is realized by butt welding between the convex points on the reinforcing rib and the convex points on the panel. The cabinet body is used to fix the panel and the door panel, and the structural strength of the cabinet body is improved by arranging a plurality of reinforcing ribs on the back of the panel. This LED display cabinet flattens and welds the reinforcing rib and the panel through a plurality of convex points, improving the support strength of the panel. However, the edges of the panel and the cabinet body are straight edges. During the welding operation, the relative positions between the cabinet body and the panel cannot be fixed, resulting in situations such as welding skew and welding obliquity. Moreover, the welding operation inside the cabinet housing directly acts on the cabinet body, easily generating heat on the cabinet body and the panel, thus affecting the flatness of the cabinet housing.

[0020] The following further details the specific embodiments of the present utility model. It should be understood that the description of the embodiments of the present utility model herein is not intended to limit the protection scope of the present utility model.

[0021] As Figure 1As shown in the figure, it is a schematic structural diagram of an outdoor small-pitch heavy-duty LED display cabinet provided by the present utility model. The outdoor small-pitch heavy-duty LED display cabinet includes a cabinet body 10, a panel 20 disposed on one side of the cabinet body 10, at least one horizontal partition 30 disposed inside the cabinet body 10, at least two vertical partitions 40 intersecting with the horizontal partition 30, and at least four reinforcing ribs 50 spaced apart on the panel 20. It can be imagined that the outdoor small-pitch heavy-duty LED display cabinet also includes some other functional modules, such as a welding module, an LED module, etc., which are well-known technologies to those skilled in the art and will not be elaborated here one by one.

[0022] Please refer to Figures 2 to 6 simultaneously. The cabinet body 10 includes a main body 11, at least two openings 12 opened on the main body 11, at least one reinforcing flat plate 13 disposed on the main body 11, and at least eight lifting reinforcing plates 14 disposed on one side of the main body 11.

[0023] The main body 11 is rectangularly arranged, and at three corners thereof, a first side wall 15 is turned up toward the side of the panel 20. The connections between the three first side walls 15 and the main body 11 are smoothly transitionally connected, thus avoiding weld seams left due to welding between the first side walls 15 and the main body 11, and further improving the waterproofness and aesthetics of the cabinet.

[0024] The planes where two opposite first side walls 15 are located are parallel to the length direction of the main body 11, so that the notch formed by the cabinet body 10 is filled by the panel 20. The main body 11 is recessed with a recess 16 at a position where two opposite first side walls 15 are away from the other first side wall 15, and both sides of the recess 16 are obliquely arranged. At least three male snap portions 17 are protruded at the edge of the recess 16, and the male snap portions 17 can be engaged with a part of the panel 20 to position the position between the cabinet body 10 and the panel 20, facilitating the welding operation, and the specific engagement situation will be described below.

[0025] One ventilation hood is respectively disposed on the side of the two openings 12 facing the panel 20, and at least two ventilation openings are provided on the ventilation hood. The two ventilation hoods are respectively used for the inlet and outlet of air, so as to facilitate the circulation of air inside and outside the cabinet and improve its heat dissipation effect.

[0026] The reinforcing flat plate 13 is fixedly connected to the body 11 through the cooperation of screws and studs, and the reinforcing flat plate 13 is disposed at the concave portion 16 on the body 11. The length of the reinforcing flat plate 13 matches the width of the body 11, and one side surface of the reinforcing flat plate 13 abuts against the side surface of the body 11 facing the panel 20. In this way, both ends of the reinforcing flat plate 13 respectively abut against the opposite side surfaces of the two opposite first side walls 15, so that the reinforcing flat plate 13 is supported between the two opposite first side walls 15, thereby strengthening the overall structure of the box shell.

[0027] At least four clamping portions 18 are formed at positions of the reinforcing flat plate 13 close to the male fastening portion 17. At least four of the lifting reinforcing plates 14 are respectively clamped in the four clamping portions 18 and fixed to the reinforcing flat plate 13 through welding operations. In this way, the thermal deformation generated by the welding operations is borne by the reinforcing flat plate 13, avoiding thermal deformation of the box body 10 and ensuring the flatness of the box body 10.

[0028] The four lifting reinforcing plates 14 are fixedly connected to the panel 20 through the cooperation of screws and studs, thereby further strengthening the connection structure between the box body 10 and the panel 20. The other four lifting reinforcing plates are fixedly connected to the two opposite first side walls 15 through the cooperation of screws and studs. The length of the lifting reinforcing plate 14 matches the height of the first side wall 15. One side surface of the lifting reinforcing plate 14 abuts against the first side wall 15, and its two end portions respectively abut against the opposite side surfaces of the body 10 and the panel 20. In this way, it is supported between the body 11 and the panel 20, thereby further strengthening the overall structural strength of the box shell.

[0029] One extension portion 19 is turned up on each of the two sides of the lifting reinforcing plate 14 along its length direction. The plane where the extension portion 19 is located is perpendicular to the plane where the lifting reinforcing plate 14 is located. The two end portions of the extension portion 19 respectively abut against the opposite side surfaces of the body 10 and the panel 20. In this way, the supporting surface between the body 11 and the panel 20 is increased, thereby further improving the structural strength of the box shell.

[0030] A plurality of openings 21 for installing LED modules are spaced apart on the panel 20. A rubber pad is provided in a circumferential direction on the side of the opening 21 facing the box body 10. In this way, a good waterproof function can be achieved after the LED modules are installed, so as to adapt to outdoor placement operations.

[0031] The panel 20 is bent at a position corresponding to the concave portion 16 to form a second side wall 22. The height of the second side wall 22 matches the height of the first side wall 15. In this way, when the panel 20 is covered on the box body 10, a four-sided sealed container can be formed to accommodate the LED module and provide protection for it.

[0032] At least four small holes corresponding to the lifting reinforcement plate 14 are formed in the second side wall 22. In this way, the panel 20 and the lifting reinforcement plate 14 are further fixed through the cooperation of the small holes and screw studs, thereby strengthening the structural strength of the box shell.

[0033] On the side of the second side wall 22 away from the panel 20, a flanging portion 23 is vertically bent inward. The two sides of the flanging portion 23 are obliquely arranged and match the concave portion 16. In this way, when the panel 20 is covered on the box body 10, the flanging portion 23 can be clamped in the concave portion 16 to position the relative position between the box body 10 and the panel 20. At least three female snap portions 24 are recessed in the flanging portion 23 corresponding to the positions of the three male snap portions 17. The three male snap portions 17 can be respectively clamped in the three female snap portions 24 to further position the relative position between the box body 10 and the panel 20, facilitating subsequent welding operations.

[0034] The heights of the horizontal and vertical partition plates 30 and 40 are the same as the height of the lifting reinforcement plate 14, and the horizontal and vertical partition plates 30 and 40 are vertically and crosswise arranged. In this way, the two ends of the horizontal and vertical partition plates 30 and 40 respectively abut between the box body 10 and the panel 20, thereby strengthening the overall structural strength of the box shell.

[0035] The cross-section of the reinforcing rib 50 is in a U-shape. The surface of the reinforcing rib 50 in the opening direction abuts against the surface of the panel 20. The four reinforcing ribs 50 are spaced apart and clamped on the vertical partition plate 40. In this way, the probability of deformation of the panel 20 can be reduced, thereby improving the flatness of the panel 20.

[0036] Compared with the prior art, in the outdoor small-pitch heavy-duty LED display screen box shell provided by the present utility model, the flanging portion 23 is clamped in the concave portion 16, and the male snap portion 17 is clamped in the female snap portion 24 to position the relative position between the box body 10 and the panel 20, facilitating subsequent welding operations. The four lifting reinforcement plates 14 are welded and arranged on the reinforcing flat plate 13, so that the thermal deformation generated by the welding operation is borne by the reinforcing flat plate 13, avoiding the generation of thermal deformation of the box body 10 and ensuring the flatness of the box body 10.

[0037] The above is only the preferred embodiment of the present utility model and is not intended to limit the protection scope of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are all covered within the scope of the claims of the present utility model.
