Description

Technical Field

[0001] The invention relates to the field of LED display screens, and in particular to an LED display screen installation structure and an LED display screen system. Background Art

[0002] LED display screens have been favored by more and more consumers due to their advantages such as seamless splicing, high brightness, low energy consumption, long life and stable performance. They have been widely used in schools, shopping malls, stations, stadiums and exhibitions. At the same time, consumers have higher and higher requirements for the installation and maintenance of LED display screens. At present, some LED display screens are fixed by magnetic suction. Although this method is convenient for disassembly and assembly, it is not very reliable. If the LED display screen is pulled by a large external force, when the external force is greater than the magnetic suction force, the LED display screen is likely to fall off from the fixed position, which is easy to cause damage to the screen body, and the falling display screen is easy to injure passers-by. Although some other LED display screens can fix the LED display screen more stably, their structure is more complicated. On the one hand, it increases the installation cost, and on the other hand, the disassembly and assembly process is more troublesome. Summary of the invention

[0033] First embodiment

[0034] Reference Figure 1, shows a schematic diagram of the overall structure of the LED display screen after installation in the first embodiment. The installation structure of the LED display screen in this embodiment is divided into two parts, one of which is connected to the back of the LED display screen 100, and the other is connected to the installation part 200. The installation part 200 may be an installation box, a wall, etc.

[0035] Specifically, Figures 4 to 6 As shown, the mounting structure located on the back of the LED display screen 100 includes a first fixing plate 410, a first clamping member 420, a push rod 430, an elastic member 440, a stopper 450, a stopper column 460 and other components. The first fixing plate 410 is fixed to the back of the LED display screen 100 by a threaded fastener. One end of the first clamping member 420 is hinged to the first fixing plate 410, and the first clamping member 420 can rotate relative to the first fixing plate 410 with the hinge as the center of the circle. The first clamping member 420 is provided with a recessed portion 421, which is used to be snap-connected with the mounting structure on the component 200 to be mounted.

[0036] The elastic member 440 is in a "V" shape, and includes a first elastic piece 441 and a second elastic piece 442 that are integrally connected. The first elastic piece 441 is fixedly connected to the first fixing plate 410 through a threaded fastener, and the second elastic piece 442 is fixedly connected to the first clamping member 420 through a threaded fastener. Since one end of the first clamping member 420 is fixedly connected to the elastic member 440 and the other end is hinged to the first fixing plate 410, when the first clamping member 420 rotates relative to the first fixing plate 410, the elastic member 440 will be stretched or compressed, so that the first clamping member 420 elastically rotates relative to the first fixing plate 410, that is, elastically rotates relative to the LED display screen 100. In addition, the elastic member 440 can also be a spring or an elastic member of other shapes. However, preferably, the "V"-shaped elastic piece in this embodiment is selected as the elastic member. Compared with the spring, the second elastic piece 442 in this embodiment is in surface contact with the first clamping member 420, which has higher stability and is not easily twisted during the compression process.

[0037] The push rod 430 is also hinged to the first fixing plate 410 and can rotate relative to the first fixing plate 410. A plurality of teeth 431 are provided on the push rod 430. The stopper 450 and the stopper column 460 are both fixedly connected to the first fixing plate 410. The elastic member 440 and the stopper 450 are respectively located on both sides of the first clamping member 420. When the first clamping member 420 elastically rotates relative to the first fixing plate 410, it will abut against the stopper 450.

[0038] like Figure 6As shown, the LED display screen 100 is also provided with a through hole for the force-applying tool 500 to pass through. After the force-applying tool 500 passes through the through hole, its end can contact the push rod 430, and push the force-applying tool 500 to make the push rod 430 rotate clockwise. The above-mentioned through hole needs to avoid important parts on the LED display screen 100 to avoid affecting the normal display of the LED display screen 100.

[0039] like Figure 2 , Figure 3 and Figure 6 As shown, this part of the mounting structure located on the part to be mounted 200 includes a second clamping member 310, a second fixing plate 320, a holding member 330, a ratchet 340, a pawl 350 and other components. The second clamping member 310 and the second fixing plate 320 are both fixedly connected to the part to be mounted 200. The second clamping member 310 is provided with a protrusion 311, which is used to snap-connect with the first clamping member 420 on the LED display screen 100. The holding member 330 is hinged with the second fixing plate 320, and can rotate relative to the second fixing plate 320. The ratchet 340 and the pawl 350 are both connected to the second fixing plate 320, and the ratchet 340 is meshed with the pawl 350 so that the ratchet 340 can only rotate in one direction. The ratchet 340 and the pawl 350 are located on the first side of the second fixing plate 320, and the holding member 330 is located on the second side of the second fixing plate 320.

[0040] Reference Figures 6 to 8 , the installation process of the LED display is described as follows. Figure 7 As shown, the back of the LED display screen 100 is brought close to the mounting member 200, and the protrusion 311 on the second clamping member 310 is aligned with the recess 421 on the first clamping member 420. The LED display screen 100 is pressed toward the mounting member 200, so that the protrusion 311 is gradually inserted into the recess 421. Figure 8 As shown, during the extrusion process, the first clamping member 420 will rotate counterclockwise by a certain angle under the extrusion of the second clamping member 310. When the first clamping member 420 rotates, it will squeeze the elastic member 440, making it in a compressed state. During this process, the first clamping member 420 will be supported on the stopper 450, and the stopper 450 provides a fulcrum for the rotation of the first clamping member 420. Figure 6As shown, when the protrusion 311 is completely inserted into the recess 421, the first clamping member 420 will rotate clockwise to reset under the rebound force of the elastic member 440 and abut against the stopper 450. The elastic member 440 and the stopper 450 limit the first clamping member 420, making the clamping more stable. At this time, the first clamping member 420 will be suspended on the second clamping member 310, so that the LED display screen 100 is suspended on the component to be installed 200. In order to improve the stability of the installation, multiple groups of installation structures can be set. In this embodiment, four groups of installation structures are set. In fact, it is not limited to this. The number of installation structures can be adjusted according to the area and weight of the LED display screen.

[0041] Reference Figures 9 to 11 , the disassembly process of the LED display is described as follows. Fig. 9 As shown, when the LED display screen 100 needs to be disassembled for replacement or repair, the force-applying tool 500 is passed through the through hole on the LED display screen 100, and the front end of the force-applying tool 500 is used to push the top of the push rod 430. Under the push of the force-applying tool 500, the push rod 430 will rotate clockwise, and its bottom end will contact the first clamping member 420. Fig.10 As shown, if the force-applying tool 500 is continuously pushed, and the push rod 430 rotates more, the top end of the push rod 430 will abut against the top of the abutting member 330, and the bottom end will abut against the first clamping member 420. The abutting member 330 is equivalent to a "lever" to lift the first clamping member 420 and rotate it counterclockwise. When the first clamping member 420 rotates counterclockwise, it will abut against the elastic member 440, making it in a compressed state. Fig.11 As shown, when the first clamping member 420 rotates to a certain extent, the protrusion 311 will be disengaged from the recessed portion 421, and the LED display screen 100 is completely disassembled. After the disassembly is completed, the force-applying tool 500 is withdrawn, and under the elastic force of the elastic member 440, the first clamping member 420 will rotate clockwise to reset, and drive the push rod 430 to rotate counterclockwise to reset. In this embodiment, by providing the push rod 430, the disassembly of the LED display screen 100 can be made easier, and the force-applying tool 500 can be directly inserted from the front of the LED display screen 100 and the push rod 430 can be pushed. Since the front of the LED display screen 100 is exposed, the above operation is easy to achieve.

[0042] Preferably, since the supporting member 330 is rotatably connected to the second fixing plate 320, the top end of the supporting member 330 will rotate clockwise after being supported by the push rod 430, and its bottom end will extend outward and support the blocking column 460, pushing the blocking column 460 outward, making it easier for the protrusion 311 to disengage from the recessed portion 421.

[0043] Preferably, the ratchet 340 and the pawl 350 can also be used to prevent the push rod 430 from rotating in the opposite direction during the disassembly process. The teeth 431 on the push rod 430 mesh with the ratchet 340. During the disassembly process, when the push rod 430 rotates clockwise, the ratchet 340 meshed with the teeth 431 will rotate counterclockwise accordingly. Since the elastic member 440 is in a compressed state during the disassembly process, it has a rebound tendency. If the force-applying tool 500 is temporarily released, the rebound of the elastic member 440 will cause the first clamping member 420 to rotate clockwise and reset, thereby causing the push rod 430 to rotate counterclockwise and reset. However, due to the existence of the ratchet 340 and the pawl 350, the ratchet 340 can only rotate counterclockwise. If the push rod 430 has a counterclockwise rotation tendency, the ratchet 340 cannot mesh with the teeth 431 on the push rod 430 and will not rotate clockwise accordingly, thereby inhibiting the reset of the push rod 430, so as to avoid the disassembly work being unable to be completed. Due to the ratchet 340 and the pawl 350 , when the force applying tool 500 is used to apply external force, it is not necessary to apply force continuously, so as to avoid fatigue to the force applying person.

[0044] This embodiment also provides an LED display system, including the above-mentioned LED display installation structure, and also includes an LED display 100 and a component to be installed 200. The LED display 100 and the component to be installed 200 can be disassembled and assembled through the above-mentioned installation structure.

[0045] Second embodiment

[0046] This embodiment is an alternative embodiment of the first embodiment. In this embodiment, the mounting structure only includes the first clamping member 420, the second clamping member 310 and the push rod 430. The first clamping member 420 is directly fixedly connected to the LED display screen 100 and cannot rotate relative to the LED display screen 100. The first clamping member 420 has a certain elasticity. However, in this case, when the push rod 430 is pushed, it is difficult to separate the protrusion 311 from the recessed portion 421, and the first clamping member 420 and the second clamping member 310 are easily damaged.

[0047] Third embodiment

[0048] This embodiment is an alternative embodiment to the first embodiment, and in this embodiment, there is no need to provide the ratchet 340 and the pawl 350. However, in this case, the disassembly process is unstable, and the push rod 430 may move in the reverse direction due to the rebound force of the elastic member 440, causing the protrusion 311 to be re-stuck in the recess 421, and the disassembly cannot be completed.

[0049] Fourth embodiment

[0050] This embodiment is an alternative embodiment of the first embodiment. In this embodiment, there is no need to set the stopper 460, and the abutting member 330 is directly fixedly connected to the second fixing plate 320. When the push rod 430 rotates, it abuts against the top of the abutting member 330. However, in this case, it is difficult to separate the protrusion 311 from the recessed portion 421.

[0051] Fifth embodiment

[0052] This embodiment is an alternative embodiment of the first embodiment. In this embodiment, a convex portion is provided on the first clamping member 420, and a concave portion is provided on the second clamping member 310. Alternatively, the first clamping member 420 is provided with both a convex portion and a concave portion, and the second clamping member 310 is provided with both a concave portion matching the first clamping member 420 and a convex portion matching the first clamping member 420.

[0053] Sixth embodiment

[0054] This embodiment is an alternative embodiment of the first embodiment. In this embodiment, the position where the push rod 430 rotates relative to the LED display screen 100 is called the rotation center, and the distance between the rotation center and the first end of the push rod 430 is greater than the distance between the rotation center and the second end of the push rod 430. Through this setting, the push rod can be made into a labor-saving lever, and the first clamping member 420 can be separated from the second clamping member 310 by applying a small force during disassembly.

[0055] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
