Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal splicing screens, and more specifically, to an installation structure of a liquid crystal splicing screen. Background Art

[0002] A liquid crystal splicing screen is a display technology that allows multiple liquid crystal display screens to be spliced together to form a large continuous picture, and is commonly used in places such as monitoring centers, conference rooms, and advertising displays that require large-screen displays.

[0003] Most of the current installation frames of liquid crystal splicing screens are fixed together. The liquid crystal display screens are usually fixed to the installation frame one by one through bolts. Since the liquid crystal splicing screen is composed of multiple liquid crystal display screens, once a certain liquid crystal display screen in the middle fails and needs to be disassembled and repaired, due to the small gap between the liquid crystal display screens, it is impossible to directly disassemble the liquid crystal display screen from the middle. At this time, it is necessary to first disassemble the other liquid crystal display screens around the faulty liquid crystal display screen, and only after creating enough space can the faulty liquid crystal display screen be disassembled. This process is rather cumbersome, resulting in a long time consumption and low efficiency.

[0004] Therefore, it is necessary for us to provide an installation structure for a liquid crystal splicing screen. Content of the Utility Model

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides an installation structure of a liquid crystal splicing screen.

[0006] Technical Solution: An installation structure of a liquid crystal splicing screen includes a fixing frame, a connecting plate I, a slider, and a fixing plate. The connecting plate I is slidably connected to the fixing frame. The rear part of the connecting plate I is symmetrically connected with sliders. The front side of the connecting plate I is provided with a fixing plate.

[0007] Further explanation, the fixing plate is a copper plate.

[0008] Further explanation, it also includes a connecting cylinder, a sliding rod, a sliding cylinder, a connecting plate II, a connecting plate III, a connecting plate IV, a fixing rod, a fixing block, and a first connecting spring. The front side of the fixing frame is connected with a connecting cylinder. The connecting cylinder is internally connected with a sliding rod. The rear side of the connecting plate I is connected with a sliding cylinder. The sliding cylinder is slidably connected to the connecting cylinder. The sliding cylinder is connected with the connecting plate II, the connecting plate III, and the connecting plate IV. The heights of these three connecting plates gradually decrease trapezoidally towards the left. A chute is opened on the sliding cylinder. The chute is located at the left part of the connecting plate III. The bottom of the chute is lower than the upper side surface of the connecting plate III. The left part of the connecting plate II is provided with an inclined surface. The inclined surface is located directly behind the chute. The fixing rod is slidably connected to the sliding rod. The fixing rod is located in the middle of the sliding rod. A first connecting spring is connected between the fixing rod and the sliding cylinder. The upper side surface of the connecting plate II is connected with a fixing block. A groove is opened at the front part of the fixing block. The front part of the fixing rod fits into the groove at the front part of the fixing block.

[0009] Further explanation: It further includes an ejecting spring, and an ejecting spring is connected between the connecting cylinder and the sliding cylinder.

[0010] Further explanation: It further includes a connecting block, a clamping block and a second connecting spring. The connecting blocks are symmetrically connected to the first connecting plate, the clamping blocks are symmetrically and slidably connected to the fixing plate, the clamping blocks are inserted into the connecting blocks, the fixing plate is clamped with the connecting blocks, and the second connecting springs are connected between the clamping blocks and the fixing plate.

[0011] Further explanation: It further includes a pull rod, and the pull rods are connected to the clamping blocks.

[0012] Further explanation: It further includes a limiting block, and the limiting blocks are connected to the four corners of the first connecting plate.

[0013] Further explanation: The limiting block is made of rubber material.

[0014] The beneficial effects of the present utility model are as follows:

[0015] By installing the first connecting plate and the slider, since the first connecting plate is slidably connected to the fixing frame, the fixing plate with the faulty liquid crystal display screen can be disassembled and installed only by pulling the first connecting plate outwards. The maintenance personnel only need to disassemble this faulty liquid crystal display screen, without disassembling the surrounding liquid crystal display screens, thus effectively improving the work efficiency of the maintenance personnel and making the device convenient for the installation and maintenance of the liquid crystal display screen.

Detailed implementation mode

[0023] The present utility model will now be described more fully hereinafter with reference to the accompanying drawings, in which the presently preferred embodiments of the present utility model are shown. However, the present utility model may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and fully convey the scope of the present utility model to those skilled in the art.

[0024] Embodiment: An installation structure for a liquid crystal splicing screen, as Figures 1-3 and Figure 6 shown, includes a fixing bracket 1, a connecting plate I 2, a slider 21 and a fixing plate 10. First, the corresponding number of this device is equipped according to the number of liquid crystal display screens to be installed, and the device is transported to the installation location. Then, the fixing bracket 1 is sequentially fixed at the installation location through fixing members. The connecting plate I 2 is slidably connected to the front and back of the fixing bracket 1. The rear part of the connecting plate I 2 is symmetrically connected with sliders 21. The sliders 21 can prevent the connecting plate I 2 from rotating on the fixing bracket 1 and play a limiting role. A fixing plate 10 is provided on the front side of the connecting plate I 2. The fixing plate 10 is a copper plate. The liquid crystal display screens are sequentially fixed on the fixing plate 10 through bolts to realize the installation of the liquid crystal display screens. Since the rear side of the liquid crystal display screen is in close contact with the copper plate, and the copper material has excellent thermal conductivity, rapid heat exchange can be achieved, effectively improving the heat dissipation performance of the liquid crystal display screen and helping to extend the service life of the liquid crystal display screen. When it is necessary to disassemble and repair a faulty liquid crystal display screen, since the connecting plate I 2 is slidably connected to the fixing bracket 1, only the connecting plate I 2 needs to be pulled outwards to disassemble the fixing plate 10 on which the faulty liquid crystal display screen is installed. The maintenance personnel only need to disassemble this faulty liquid crystal display screen and do not need to disassemble the surrounding liquid crystal display screens, thus effectively improving the work efficiency of the maintenance personnel and making this device convenient for the installation and maintenance of liquid crystal display screens.

[0025] As Figure 4 and Figure 5As shown in the figure, it further includes a connecting cylinder 3, a sliding rod 31, a sliding cylinder 4, a connecting plate II 41, a connecting plate III 42, a connecting plate IV 43, a fixing rod 5, a fixing block 6, a first connecting spring 7 and an ejecting spring 8. Four connecting cylinders 3 are connected to the front side of the fixing frame 1. A sliding rod 31 is connected inside each connecting cylinder 3. Four sliding cylinders 4 are connected to the rear side of the connecting plate I 2. The sliding cylinders 4 are slidably connected to the connecting cylinders 3 in the front and rear directions. A connecting plate II 41, a connecting plate III 42 and a connecting plate IV 43 are connected to each sliding cylinder 4. The heights of these three connecting plates gradually decrease trapezoidally towards the left. A sliding groove 44 is provided on each sliding cylinder 4. The sliding grooves 44 are all located in the left part of the connecting plate III 42. The bottom of the sliding groove 44 is lower than the upper side surface of the connecting plate III 42. An inclined surface 45 is provided on the left part of each connecting plate II 41. The inclined surfaces 45 are all located directly behind the sliding grooves 44. A fixing rod 5 is slidably connected to the sliding rod 31 in the left and right directions. The fixing rod 5 is located in the middle of the sliding rod 31 and is not completely vertical but slightly deviated to the right vertically. A first connecting spring 7 is connected between the fixing rod 5 and the sliding cylinder 4. A fixing block 6 is connected to the upper side surface of each connecting plate II 41. A groove is provided in the front part of the fixing block 6. The front part of the fixing rod 5 fits into the groove in the front part of the fixing block 6. An ejecting spring 8 is connected between the connecting cylinder 3 and the sliding cylinder 4 through a spring seat. When the liquid crystal display screen is pushed backward, the connecting plate I 2 will drive the sliding cylinder 4 to move backward, and the ejecting spring 8 will be compressed. During this process, the fixing rod 5 will disengage from the groove in the front part of the fixing block 6 and shift to the left, releasing the liquid crystal display screen. Due to the resilience of the ejecting spring 8, the sliding cylinder 4 will move forward, causing the fixing rod 5 to gradually move leftward and downward along the connecting plate II 41, the connecting plate III 42 and the connecting plate IV 43, and then slide into the internal sliding groove. During this process, the first connecting spring 7 on the left will be compressed. With the resilience of the ejecting spring 8, the fixing rod 5 will move backward along the internal sliding groove and then displace along the inclined surface to the rear part of the connecting plate II 41. During this process, the fixing rod 5 will be subjected to the restoring force of the first connecting spring 7 on the left, causing the fixing rod 5 to move along the left side surface of the fixing block 6. Since the area of the rear part of the fixing block 6 becomes narrower, the vertically slightly deviated-to-the-right fixing rod 5 will displace to the right side of the fixing block 6 to facilitate the subsequent re-fitting of the fixing rod 5 with the groove in the front part of the fixing block 6; the process of the fixing rod 5 moving backward is the process of the sliding cylinder 4 being pushed out of the connecting cylinder 3, enabling the maintenance personnel to only push the liquid crystal display screen backward once, and the liquid crystal display screen will be ejected, further improving the disassembly efficiency of the device. When re-docking the sliding cylinder 4 with the corresponding connecting cylinder 3, push the liquid crystal display screen backward, and the sliding cylinder 4 will slide backward in the connecting cylinder 3. During this process, the ejecting spring 8 will be compressed, and the right side of the fixing block 6 will move along the vertically slightly deviated-to-the-right fixing rod 5, and the first connecting spring 7 on the right will be compressed. When the fixing rod 5 disconnects from the right side of the fixing block 6, the first connecting spring 7 on the right will drive the fixing rod 5 to move leftward, causing the fixing rod 5 to re-fit with the groove in the front part of the fixing block 6, thereby re-fixing the liquid crystal display screen.

[0026] AsFigure 6 As shown in the figure, it further includes a connecting block 9, a clamping block 11, a second connecting spring 111 and a pull rod 12. Connecting blocks 9 are symmetrically connected to the left and right on the connecting plate Ⅰ2. Clamping blocks 11 are symmetrically and slidably connected to the left and right on the fixing plate 10. The clamping blocks 11 are inserted into the connecting blocks 9, and the fixing plate 10 is clamped to the connecting blocks 9. Second connecting springs 111 are connected between the clamping blocks 11 and the fixing plate 10 through spring seats; Pull rods 12 are connected to the clamping blocks 11. When the fixing plate 10 needs to be removed from the connecting plate Ⅰ2, the pull rods 12 are simultaneously squeezed towards the middle, and the clamping blocks 11 will be driven to move towards the middle together, and the second connecting springs 111 are compressed. When the clamping blocks 11 are disengaged from the connecting blocks 9, pulling the pull rods 12 forward can remove the fixing plate 10 from the connecting plate Ⅰ2, which is convenient for subsequently disassembling the liquid crystal display screen from the fixing plate 10. After the repair is completed, when the fixing plate 10 needs to be fixed back to the connecting plate Ⅰ2, the pull rods 12 are simultaneously squeezed towards the middle, and the second connecting springs 111 are compressed. When the positions of the clamping blocks 11 and the connecting blocks 9 are aligned, the pull rods 12 are released, and the second connecting springs 111 will drive the clamping blocks 11 to rebound and reset, so that the clamping blocks 11 are re-inserted into the connecting blocks 9 and the fixing plate 10 is re-fixed.

[0027] As Figure 1 , Figure 2 and Figure 6 As shown in the figure, it further includes a limiting block 13. Limiting blocks 13 are connected to the four corners of the connecting plate Ⅰ2. The limiting blocks 13 are made of rubber. The limiting blocks 13 can correct the position of the fixing plate 10 when installing the fixing plate 10, so that the clamping blocks 11 can be quickly and accurately docked and inserted into the connecting blocks 9, thereby realizing quick fixation of the fixing plate 10. The rubber limiting blocks 13 are not easy to wear the fixing plate 10 and the limiting blocks 13 themselves, and the rubber material has toughness and can better correct the placement position of the fixing plate 10.
