[0001] The utility model belongs to the technical field of display screens, and particularly relates to a spliced ​​display screen. Background Art

[0002] A display is a display tool that displays certain electronic files on the screen through a specific transmission device and then reflects them to the human eye. According to different manufacturing materials, it can be divided into: cathode ray tube display, plasma display, liquid crystal display, etc. With the rapid development of entertainment and advertising industries, large-screen displays are widely used, especially in TV stations, evening parties, stages or large outdoor advertising sites. Many large-screen displays are made of multiple display units spliced ​​together to form an existing spliced ​​display.

[0003] In the prior art, after searching, it was found that a Chinese patent disclosed "a spliced ​​display screen" with the application number "CN202121460660.X". This patent mainly turns on the water pump to allow the cooling water inside the water tank to enter the guide pipe through the water pump and the inlet pipe, so that the cooling water inside the guide pipe can absorb the heat emitted by the display screen, thereby preventing excessive heat accumulation inside the display screen from causing damage to the display screen.

[0004] However, the display screen of the device is connected with a large number of bolts and hinges, and large tools are needed to assist in the installation and disassembly of the device. This process is time-consuming and laborious, the installation efficiency is low, and it is not convenient for operators to complete the work quickly. Utility Model Content

By providing a fixing mechanism, the display can be disassembled and assembled with the use of simple auxiliary tools, thereby greatly improving the installation efficiency of the display screen. It solves the problem that the connection of the display screen of the above-mentioned device uses a large number of bolts and hinges for hinged connection, and large tools need to be used for assistance when the device is installed and disassembled, which is a relatively time-consuming and laborious process and has low installation efficiency.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a spliced ​​display screen, comprising a bottom plate and a fixed frame, wherein a fixing mechanism and a shock absorbing mechanism are arranged on the bottom plate, and the fixing mechanism comprises a connecting component and a resetting component;

[0008] The connection component includes four displays arranged on a fixed frame. A U-shaped mounting block is fixedly connected to the back of each of the several displays. A number of connection holes are provided on each of the U-shaped mounting blocks. Two mounting grooves are provided on the back of the fixed frame. A number of first sliding rods penetrate through the two mounting grooves. The first sliding rods are slidably connected to the mounting grooves. A connecting plate is fixedly connected to the ends of three of the first sliding rods. A rotating rod is rotatably connected to the inner wall of each of the two mounting grooves.

The outer surfaces of the two clamping blocks are slidably connected to the outer surfaces of a number of connecting plates. The outer surfaces of a number of first sliding rods are slidably connected to the inner walls of a number of connection holes.

[0009] Further, the reset component includes a first spring wound around the outer surfaces of a number of first sliding rods. One corresponding end of each of the first springs is fixedly connected to the inner wall of the mounting groove. The ends of the first springs are fixedly connected to the outer surfaces of a number of connecting plates. A knob is fixedly connected to the left end of each of the two rotating rods.

[0010] Further, the shock absorption mechanism includes a first buffer component and a second buffer component. The first buffer component includes two support columns fixedly connected to the top surface of the bottom plate. A mounting plate is fixedly connected to the back of the fixed frame. Two second sliding rods are fixedly connected to the bottom surface of the mounting plate. A sliding groove is provided inside each of the two support columns. The two second sliding rods extend into the inside of the sliding grooves. The second sliding rods are slidably connected to the support columns. A limiting block is fixedly connected to the outer surface of each of the two second sliding rods. A second spring is wound around the outer surface of each of the two second sliding rods.

The bottom ends of the two second springs are fixedly connected to the top surface of the support columns.

[0011] Further, the second buffer component includes a piston fixedly connected to the bottom ends of the two second sliding rods. The outer surface of each of the two pistons is slidably connected to the inner wall of each of the two sliding grooves. A third spring is wound around the outer surface of each of the two second sliding rods. The top ends of the two third springs are fixedly connected to the inner walls of the two sliding grooves.

[0014] The utility model has the following beneficial effects:

[0015] 1. By setting a fixing mechanism, when installing the display, the knob can be rotated to synchronously rotate the rotating rod and the clamping block, squeezing the connecting plates on both the upper and lower sides of the rotating rod to move away from each other. At the same time, the first sliding rod slides into the connecting hole to fix the U-shaped mounting block on the back of the display. When it is necessary to disassemble the display, the knob can be rotated to separate the clamping block from the connecting plate. At the same time, under the action of the first spring, the connecting plates on both the upper and lower sides of the rotating rod approach each other, and the first sliding rod slides out of the connecting hole, and then the display can be disassembled. This mechanism is simple to operate, and the display can be disassembled and assembled with the help of simple auxiliary tools, such as a wrench or a fixed clamp, greatly improving the installation efficiency of the display.

[0016] 2. By setting a shock-absorbing mechanism, when the whole device is transported and moved, due to the rough road surface, it is easy to generate shaking. And the connection between the displays is relatively tight, and this shaking is very easy to cause the displays to collide with each other, thus damaging the displays. With the mutual cooperation between the third spring and the second spring, the shaking amplitude during movement can be well reduced, thus ensuring to the greatest extent that the displays will not be damaged and ensuring the stability of the whole device during movement.

[0017] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] Please refer to Figure 1-5 As shown, the present invention is a spliced display screen, including a bottom plate 1 and a fixed frame 3. A fixing mechanism and a shock absorption mechanism are arranged on the bottom plate 1. The fixing mechanism includes a connection component and a reset component;

[0028] The connection component includes four displays 2 arranged on the fixed frame 3. The back surfaces of several displays 2 are fixedly connected with C-shaped mounting blocks 21. Several connection holes 22 are arranged on several C-shaped mounting blocks 21. Two mounting grooves 311 are arranged on the back surface of the fixed frame 3. Several first sliding rods 312 penetrate through the two mounting grooves 311. The first sliding rods 312 are slidably connected with the mounting grooves 311. The ends of three first sliding rods 312 are fixedly connected with a connection plate 314. The inner walls of the two mounting grooves 311 are rotatably connected with rotating rods 315. Clamping blocks 316 are fixedly connected to the outer surfaces of the two rotating rods 315. The outer surfaces of the two clamping blocks 316 and the outer surfaces of several connection plates 314 are slidably connected. The outer surfaces of several first sliding rods 312 and the inner walls of several connection holes 22 are slidably connected.

[0029] Among them, as Figure 4 and Figure 5 shown, the reset component includes first springs 313 wound around the outer surfaces of several first sliding rods 312. One corresponding end of several first springs 313 is fixedly connected with the inner wall of the mounting groove 311. The ends of several first springs 313 are fixedly connected with the outer surfaces of several connection plates 314. The left ends of the two rotating rods 315 are fixedly connected with knobs 317.

[0030] By setting a reset component and cooperating with a connecting component, when installing the display 2, the knob 317 can be rotated to synchronously rotate the rotating rod 315 and the clamping block 316, squeezing the connecting plates 314 on the upper and lower sides of the rotating rod 315 to move away from each other. At the same time, the first sliding rod 312 slides into the connecting hole 22 to fix the U-shaped mounting block 21 on the back of the display 2. When it is necessary to disassemble the display 2, the knob 317 can be rotated to separate the clamping block 316 from the connecting plate 314. At the same time, under the action of the first spring 313, the connecting plates 314 on the upper and lower sides of the rotating rod 315 approach each other, and the first sliding rod 312 slides out of the connecting hole 22, and then the display 2 can be disassembled. This mechanism is simple to operate and can disassemble and assemble the display 2 with a simple auxiliary tool, greatly improving the installation efficiency of the display 2.

[0031] As shown in Figure 2 and Figure 4 The shock absorption mechanism includes a first buffer component and a second buffer component. The first buffer component includes two support columns 4 fixedly connected to the top surface of the bottom plate 1. The back surface of the fixed frame 3 is fixedly connected with a mounting plate 31. The bottom surface of the mounting plate 31 is fixedly connected with two second sliding rods 32. The inside of both support columns 4 is provided with sliding grooves 33. Both second sliding rods 32 extend into the inside of the sliding grooves 33. The second sliding rods 32 are slidably connected with the support columns 4. The outer surfaces of both second sliding rods 32 are fixedly connected with limit blocks 35. The outer surfaces of both second sliding rods 32 are wound with second springs 36. The top ends of both second springs 36 are fixedly connected with the bottom surfaces of the two limit blocks 35. The bottom ends of both second springs 36 are fixedly connected with the top surfaces of the support columns 4.

[0032] By setting the first buffer component, the second sliding rod 32 and the second spring 36 cooperate with each other, so that while the support column 4 supports the fixed frame 3, it can effectively reduce the vibration during installation.

[0033] As shown in Figure 4 The second buffer component includes pistons 34 fixedly connected to the bottom ends of the two second sliding rods 32. The outer surfaces of both pistons 34 are slidably connected with the inner walls of the two sliding grooves 33. The outer surfaces of both second sliding rods 32 are wound with third springs 37. The top ends of both third springs 37 are fixedly connected with the inner walls of the two sliding grooves 33. The bottom ends of both third springs 37 are fixedly connected with the top surfaces of the two pistons 34.

[0034] By providing the second buffer component, when the entire device is being transported and moved, it is easy to shake due to the rugged road surface, and the connection between the displays 2 is relatively tight. This shaking can easily cause bumps between the displays 2, thereby damaging the displays 2. With the mutual cooperation between the third spring 37 and the second spring 36, the shaking amplitude during movement can be well reduced, thereby ensuring to the greatest extent that the displays 2 will not be damaged, ensuring the stability of the entire device during movement.

[0035] Among them Figure 2 As shown, a plurality of bevel plates 38 are fixedly connected between the top surface of the bottom plate 1 and the outer surfaces of the two support columns 4 .

[0036] By providing a plurality of beveled plates 38, the force bearing area at the bottom of the device is increased, thereby increasing the stability of the device.

[0037] Among them Figure 1 and Figure 3 As shown, a plurality of heat dissipation holes 23 are disposed on the backs of the plurality of displays 2 , and a plurality of universal wheels 5 are disposed on the bottom surface of the bottom plate 1 .

[0038] By providing a plurality of heat dissipation holes 23, the back of the display 2 can be effectively cooled to prevent the display 2 from being overheated when in use.

[0039] A specific application of this embodiment is as follows: By providing a fixing mechanism, when installing the display 2, the knob 317 can be rotated to synchronously rotate the rotating rod 315 and the clamping block 316, squeezing the connecting plates 314 on both the upper and lower sides of the rotating rod 315 to move them away from each other. At the same time, the first sliding rod 312 slides into the connecting hole 22 to fix the U-shaped mounting block 21 on the back of the display 2. When it is necessary to disassemble the display 2, the knob 317 can be rotated to separate the clamping block 316 from the connecting plate 314. At the same time, under the action of the first spring 313, the connecting plates 314 on both the upper and lower sides of the rotating rod 315 approach each other, and the first sliding rod 312 slides out of the connecting hole 22, then the display 2 can be disassembled. This mechanism is simple to operate and can disassemble and assemble the display 2 with the use of simple auxiliary tools, greatly improving the installation efficiency of the display 2; By providing a shock-absorbing mechanism, when the whole device is transported and moved, due to the rough road surface, it is easy to generate晃动. And the connection between the displays 2 is relatively tight, and this kind of晃动 is very likely to cause the displays 2 to collide with each other, thus damaging the displays 2. With the mutual cooperation between the third spring 37 and the second spring 36, the amplitude of the晃动 during movement can be well reduced, thereby ensuring to the greatest extent that the displays 2 will not be damaged and ensuring the stability of the whole device during movement; By providing a number of bevel plates 38, the stress area at the bottom of the device is increased, and the stability of the device is increased; By providing a number of heat dissipation holes 23, it can effectively dissipate heat from the back of the display 2, preventing the display 2 from overheating during use.
