Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to an outdoor LED display screen with a windproof function. Background Art

[0002] LED display is a flat panel display, which is composed of small LED module panels. It controls the display mode of semiconductor light emitting diodes and is generally used to display various information such as text, images, videos, and video signals. Outdoor LED display usually appears in the form of outdoor media. Outdoor media refers to the media for publishing advertising information set up in outdoor places such as the roofs of major buildings, in front of commercial areas, and on the roadsides.

[0003] The existing outdoor LED display screens do not have a windproof function when they are actually put into use. Because the LED display screens are placed outdoors for use, when the outdoor wind speed level is high, the LED display screen will cause the support frame to be loaded due to the large front wind-facing force area, causing the support frame to be damaged. The LED display screen will also break due to overload, resulting in the LED display screen being unable to continue to be put into use. Utility Model Content

[0004] The utility model aims to provide an outdoor LED display screen with windproof function, so as to solve the problem that the display direction of the existing curved LED display screen proposed in the above background technology is not convenient for multi-directional adjustment.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an outdoor LED display screen with windproof function, comprising a display screen body and a support frame supporting it, a transparent protective plate is fixedly arranged in front of the display screen body by a fixing column, and side windproof plates are arranged on both sides of the display screen body.

[0006] Preferably, a mounting groove for snap-fitting the side edge of the display screen body is provided on the inner side of the side wind shield plate, and a fastening bolt is provided through the bottom of the mounting groove.

[0007] Preferably, a movably connected abutment disc is provided on the top of the fastening bolt.

[0008] Preferably, elastic contact plates are provided on the sides of the side wind shielding plates.

[0009] Preferably, spring positioning pins connected to the end surfaces of the elastic contact plates are provided through both sides of the front of the transparent protective plate.

[0010] Preferably, a special-shaped exhaust duct is provided through the interior of the side wind shield.

[0011] Preferably, the opening of the special-shaped exhaust duct is provided with a filter.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. This kind of outdoor windproof LED display screen has such an arrangement that when the display screen is put into outdoor use and strong wind weather occurs, the transparent protective plate arranged in front of the display screen can be deformed into an arc shape under the action of wind force, thereby having the effect of guiding the strong wind. When the strong wind affects the display screen from the side, the strong wind will be discharged through the side windproof plate, which can effectively reduce the impact of the strong wind on the side of the display screen.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3The utility model provides a technical solution: an outdoor LED display screen with windproof function, comprising a display screen body 1 and a support frame 6 supporting it, a transparent protective plate 2 is fixedly arranged in front of the display screen body 1 through a fixing column 3, and side windproof plates 4 are sleeved on both sides of the display screen body 1. The transparent protective plate 2 is made of a hard PVC transparent plate. Because the transparent protective plate 2 is arranged in front of the display screen body 1 through two fixing columns 3, and there are no fixing devices on both sides, when strong wind blows on the front of the display screen body 1, the strong wind will first contact the transparent protective plate 2 arranged in front of the display screen body 1. Because the transparent protective plate 2 is fixed in front of the display screen body 1 through two fixing columns 3 at both ends in the middle of the front of the display screen body 1, when the transparent protective plate 2 is squeezed by the wind, the two sides of the transparent protective plate 2 will bend due to the force, and the transparent protective plate 2 will not change due to the fixing columns 3, so that the transparent protective plate 2 is arc-shaped, and then the transparent protective plate 2 can better guide the oncoming wind when affected by the wind, so as to achieve the purpose of reducing the impact of the wind on the display screen body 1, and when the side of the display screen body 1 is affected by the wind, the wind can circulate through the side wind shield 4, so as to reduce the impact of the wind on the side of the display screen body 1.

[0020] Preferably, the inner side of the side wind shield 4 is provided with a mounting groove 401 for engaging the side edge of the display screen body 1, and a fastening bolt 403 is provided through the bottom of the mounting groove 401. The provision of the mounting groove 401 allows the side wind shield 4 to be more conveniently mounted to both sides of the display screen body 1.

[0021] Preferably, a movable contact disc is provided on the top of the fastening bolt 403. When the side wind shields 4 installed on both sides of the display screen body 1 are fastened and fixed by rotating the fastening bolt 403, the contact disc will not rotate with the rotation of the fastening bolt 403, so that the contact disc can be pushed to fit more closely with the outer surface of the display screen body 1 by rotating the fastening bolt 403.

[0022] Preferably, an elastic resistance plate 402 is provided on the side of the side wind shield plate 4. The elastic resistance plate 402 can keep the transparent protection plate 2 parallel to the display screen body 1 by its own elastic force when the transparent protection plate 2 is not affected by external forces.

[0023] Preferably, spring positioning pins 5 connected to the end faces of the elastic abutment plate 402 are provided through both sides of the front of the transparent protection plate 2. When the transparent protection plate 2 is connected to the elastic abutment plate 402, the transparent protection plate 2 can be more stable.

[0024] Preferably, a special-shaped exhaust duct 405 is provided inside the side wind shield 4. When the side of the display screen body 1 is affected by wind, the wind will be diverted to the outside through the special-shaped exhaust duct 405 in the side wind shield 4, so as not to affect the side of the display screen body 1.

[0025] Preferably, the opening of the special-shaped exhaust duct 405 is provided with a filter 404. When the special-shaped exhaust duct 405 conducts the air flow, the filter 404 can effectively filter the impurities or other substances mixed in the air flow.

[0026] During the specific implementation process, when the display screen body 1 is put into use and there is a strong wind flow, if the strong wind is facing the front of the display screen body 1, the transparent protective plate 2 arranged in front of the display screen body 1 will bend and deform on both sides with the fixed column 3 as the midpoint due to the wind pressure of the strong wind (the spring positioning pins 5 arranged on both sides in front of the transparent protective plate 2 will be compressed due to the force), thereby causing the transparent protective plate 2 to form an arc to guide the flow, thereby greatly reducing the impact of the strong wind on the display screen body 1, and when the strong wind blows on the display screen body 1 from the side, the strong wind will be discharged through the special-shaped exhaust duct 405 in the side wind shield 4, so that the extrusion force generated by the strong wind will leak out and will not affect the side of the display screen body 1.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
