This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, a display screen includes an adjusting device 10, a display unit 20 and a frame 30, wherein the adjusting device 10 is fixed to the frame 30, and the display unit 20 is connected to the frame 30 via the adjusting device 10. The display unit 20 may be an LED display technology, an lcd display technology, or the like.
Referring to fig. 2 and 3, the adjusting device 10 includes a base 1 and a connecting member 2, and the base 1 and the frame 30 are fixedly connected in a specific manner: the base 1 has an extension 101 in the lateral direction, and the extension 101 is connected to the frame 30 via a screw 3. The extending portions 101 are two symmetrically arranged. The base 1 and the connecting piece 2 are rotatably connected. The base 1 and the connecting piece 2 can be rotatably connected in a specific manner that: the base 1 is provided with a second cylindrical mounting hole 102 (which may be a blind hole or a through hole), one end of the connecting member 2 is cylindrical and is inserted into the second mounting hole 102 (equivalently, the connecting member 2 may be provided with the second mounting hole 102, and a part of the base 1 is inserted into the second mounting hole 102), so as to realize the rotatable connection between the base 1 and the connecting member 2. The rotation center line a of the connector 2 is the center line of the second mounting hole 102. The base 1 is T-shaped. The connecting piece 2 is rotatably connected to the display unit 20, specifically, the connecting piece 2 is provided with a first connecting structure 201 for connecting the display unit 20, specifically, the first connecting structure 201 may be a cylindrical connecting hole (cylindrical hole), and a connecting column of the display unit 20 is inserted into the connecting hole (equivalently, the first connecting structure 201 may also be a cylindrical connecting column, which is inserted into the connecting hole of the display unit 20), so as to realize the rotatable connection between the connecting piece 2 and the display unit 20. The center line B of the first connecting structure 201 is the center line of the connecting hole. The center line B of the first connecting structure 201 and the rotation center line a of the connecting member 2 are not aligned (i.e. the second mounting hole 102 is not concentric with the first connecting structure 201), and when the connecting member 2 rotates relative to the base 1, the display units 20 are displaced to adjust the distance between two adjacent display units 20. When the connecting member 2 rotates relative to the base 1, on one hand, the displacement of the display unit 20 moving is gradually increased when the connecting member rotates 0-180 degrees, and the displacement of the display unit 20 starts to gradually decrease when the connecting member rotates 180-360 degrees, so that the rotation angle of the connecting member 2 and the base 1 is limited within 360 degrees, and preferably, the rotation angle of the connecting member 2 and the base 1 is limited within 180 degrees. The base 1 is provided with scales 4 which represent the displacement of the display unit 20 in the process of rotating the connecting piece 2.
Referring to fig. 2 and 3, in order to limit the rotation angle between the connecting member 2 and the base 1, the adjusting device 10 further includes a limiting member 5, and the limiting member 5 is fixed to the connecting member 2 and is matched with the second connecting structure of the base 1 to limit the rotation angle between the connecting member 2 and the base 1. The second connection structure comprises a limit groove 103 which is arranged on the side wall of the base 11 and extends along the circumferential direction of the base 1, and when the connecting piece 2 is opposite to the base 1 and rotates, the limiting piece 5 slides in the limit groove 103 to play a role in guiding and limiting. The limiting groove 103 can be a through hole or a blind hole. The extension length of the limiting groove 103 is a quarter of the circumference of the base 1, so as to limit the rotation angle of the connecting piece 2 and the base 1 within 90 degrees. Because the rotation angle is too large, the operation is not easy during the operation, the inventor finds that the rotation angle is 90 degrees, the requirement of distance adjustment of the display unit 20 can be met, the operation is convenient, and the rotation angle is limited to 90 degrees. The specific connection mode of the limiting member 5 and the connecting member 2 is as follows: the limiting part 5 is cylindrical, the side wall of the connecting part 2 is provided with a first mounting hole 202, one end of the limiting part 5 is inserted into the first mounting hole 202, the limiting part 5 is in interference fit with the first mounting hole 202, and the other end of the limiting part 5 is in sliding connection with the limiting groove 103. In order to realize that a part of the limiting member 5 can be conveniently inserted into the first mounting hole 202, and meanwhile, the limiting member 5 can be in interference fit with the first mounting hole 202, a protrusion 501 is circumferentially arranged at a mounting part where the limiting member 5 is matched with the first mounting hole 202, so that the interference fit between the limiting member 5 and the connecting member 2 is realized.
Referring to fig. 3, in order to prevent the distance between the display unit 20 from being changed after the distance between the connection member 2 and the base 1 is adjusted due to self-rotation caused by shaking during transportation or use. A resistance piece is arranged between the connecting piece 2 and the base 1 to increase the friction force between the base 1 and the connecting piece 2. The resistance piece can include silica gel circle 6, silica gel circle 6 cover is established on the connecting piece 2, with the connecting piece 2 is located together in the base 1. In order to limit the position of the silica gel ring 6, an annular accommodating groove 203 is formed in the connecting piece 2, and at least one part of the silica gel ring 6 is arranged in the accommodating groove 203.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
