A type of splicing LCD display

Abstract

This utility model relates to the field of splicing LCD display technology, and in particular to a splicing LCD display, including a splicing frame. A partition plate is fixedly connected to the inner wall of the splicing frame, and several linear array guide rods are fixedly connected to the left and right sides of the partition plate and the splicing frame. The advantages of this utility model are: the operator can pull the locking rod outward to move it out of the locking hole, thus releasing the lock on the sliding plate. Pulling the extension frame outward moves the sliding plate along the guide rods until the sliding plate reaches the appropriate position, at which point the locking bolt is exposed. Removing the locking bolt releases the lock on the rotating frame. Pulling the rotating frame outward then causes it to rotate around the connecting rod until the rotating frame is perpendicular to the splicing frame, exposing the locking components on the back of the LCD display body. This facilitates the operator's disassembly of the LCD display body using tools, greatly improving the efficiency of replacing the LCD display body.

Description

Technical Field

[0001] This utility model relates to the field of splicing LCD display technology, and in particular to a splicing LCD display. Background Technology

[0002] A liquid crystal display (LCD) is a widely used flat-panel display that displays images by controlling the alignment of liquid crystal molecules. LCDs offer advantages such as low power consumption, small size, and low radiation, and are widely used in various electronic devices including televisions, computer monitors, calculators, electronic watches, and mobile phone screens. The display principle of an LCD utilizes a liquid crystal solution in two polarizing materials. When an electric current passes through the liquid, the crystal molecules rearrange themselves, allowing light to pass through or be blocked, thereby achieving the purpose of displaying an image.

[0003] The installation location of the video wall unit is crucial during the installation of a splicing LCD display. For wall-mounted units, the installation process typically involves the following steps: First, multiple LCD display units need to be locked onto the splicing unit, ensuring uniform spacing and seamless image splicing; then, screws are used to secure the entire splicing unit to the wall, ensuring a firm and stable installation. However, in practical applications, the installation and maintenance of splicing LCD displays present some challenges. Especially when a single LCD display unit malfunctions and needs replacement, the locking components are usually hidden on the back of the display, making disassembly difficult and complex. This not only increases the difficulty and time cost of repairs but may also cause unnecessary damage to the LCD display. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a splicing LCD display screen to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a splicing LCD display screen, including a splicing frame. A partition plate is fixedly connected to the inner wall of the splicing frame. Several linearly arrayed guide rods are fixedly connected to both sides of the partition plate and the splicing frame. Two symmetrically arranged sliding plates are fixedly connected to the outside of the guide rods. The partition plate is located between the two sliding plates. An extension frame is fixedly connected to one side of each sliding plate. Both the extension frame and the sliding plate are slidably connected to the splicing frame. Two symmetrically arranged connecting rods are fixedly connected to the front of each extension frame. A rotating frame is rotatably connected to the outer surface of each connecting rod. A locking bolt is rotatably connected to the side of the rotating frame near the partition plate. The threaded portion of the locking bolt is threadedly connected to the sliding plate. An LCD display screen body is fixedly mounted on the front of each rotating frame by bolts. Several LCD display screen bodies are parallel to the splicing frame. Several symmetrically arranged support plates are fixedly connected to the inner wall of the splicing frame. A spring is fixedly connected to one side of each support plate. A locking rod is fixedly connected to the side of the spring away from the support plate. The locking rod passes through the support plate and engages with the sliding plate.

[0007] Preferably, in any of the above embodiments, the top and bottom of the skateboard are provided with locking holes, and the locking rod passes through the support plate and engages with the skateboard through the locking holes.

[0008] Preferably, one side of the slide plate has a plurality of linearly arrayed guide holes, and the slide plate is slidably connected to the guide rod through the guide holes.

[0009] Preferably, in any of the above embodiments, the slide plate has a threaded hole on the side near the partition plate, and the screw portion of the locking bolt is threadedly connected to the slide plate through the threaded hole.

[0010] Preferably, one side of the rotating frame has a through-hole, and the rotating frame is rotatably connected to the connecting rod through the rotating hole. The depth of the rotating hole is equal to the length of the connecting rod.

[0011] Preferably, in any of the above embodiments, the top surface of the slide plate is fixedly connected to two symmetrically arranged pads, and the bottom surfaces of the two pads are respectively in contact with the bottom surfaces of the two rotating frames.

[0012] Preferably, one side of the expansion frame is fixedly connected to two symmetrically arranged card plates, and two symmetrically arranged card slots are opened on both the left and right sides of the assembly frame, and the card plates are engaged with the assembly frame through the card slots.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: When a faulty LCD screen needs repair or replacement, the operator can pull the locking lever outward to move it out of the locking hole, thus releasing the lock on the slide plate. Pulling the extension frame outward will cause the slide plate to slide outward along the guide rod until the slide plate moves to the appropriate position, at which point the locking bolt will be exposed. The locking bolt can then be removed to lock the rotating frame. At this point, pulling the rotating frame outward will cause it to rotate around the connecting rod until the rotating frame is perpendicular to the assembly frame. The locking components on the back of the LCD screen will then be exposed, making it easy for operators to disassemble the LCD screen using tools, greatly improving the efficiency of replacing the LCD screen.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0017] like Figures 1 to 7As shown, a splicing LCD display includes a splicing frame 1. A partition plate 2 is fixedly connected to the inner wall of the splicing frame 1. Several linearly arrayed guide rods 3 are fixedly connected to both sides of the partition plate 2 and the splicing frame 1. Two symmetrically arranged sliding plates 4 are fixedly connected to the outside of the guide rods 3. The partition plate 2 is located between the two sliding plates 4. An extension frame 5 is fixedly connected to one side of each sliding plate 4. Both the extension frame 5 and the sliding plate 4 are slidably connected to the splicing frame 1. Two symmetrically arranged connecting rods 6 are fixedly connected to the front of each extension frame 5. A rotatable connector is rotatably connected to the outer surface of each connecting rod 6. Each rotating frame 7 has a locking bolt 8 rotatably connected to the side of the rotating frame 7 near the partition plate 2. The screw part of the locking bolt 8 is threadedly connected to the slide plate 4. Each rotating frame 7 has an LCD screen body 9 fixedly installed on its front by bolts. Several LCD screen bodies 9 are parallel to the assembly frame 1. Several symmetrically arranged support plates 10 are fixedly connected to the inner wall of the assembly frame 1. A spring 11 is fixedly connected to one side of the support plate 10. A locking rod 12 is fixedly connected to the side of the spring 11 away from the support plate 10. The locking rod 12 passes through the support plate 10 and is engaged with the slide plate 4.

[0018] As an optional technical solution of this utility model, locking holes 13 are provided at the top and bottom of the slide plate 4. The locking rod 12 passes through the support plate 10 and is engaged with the slide plate 4 through the locking holes 13. The locking holes 13 and locking rod 12 at the top and bottom of the slide plate 4 achieve a double locking function. This symmetrical locking structure ensures that the slide plate 4 will not move in any direction when it is fixed, which greatly enhances the stability of the display splicing. At the same time, the precise positioning of the locking holes 13 allows the locking rod 12 to be quickly aligned and inserted, which simplifies the installation and adjustment process and improves the operating efficiency.

[0019] As an optional technical solution of this utility model, a number of linear array guide holes 14 are provided through one side of the slide plate 4. The slide plate 4 is slidably connected to the guide rod 3 through the guide holes 14. The sliding connection design between the linear array guide holes 14 on one side of the slide plate 4 and the guide rod 3 provides precise guidance for the adjustment of the display screen position. The arrangement of multiple guide holes 14 ensures the stability of the slide plate 4 during the sliding process and avoids jamming. This design makes the position adjustment of the display screen unit smoother. At the same time, the fit gap between the guide rod 3 and the guide holes 14 is precisely calculated, which ensures both sliding flexibility and prevents shaking.

[0020] As an optional technical solution of this utility model, the slide plate 4 has a threaded hole 15 on the side near the partition plate 2. The screw part of the locking bolt 8 is threadedly connected to the slide plate 4 through the threaded hole 15. The threaded connection between the threaded hole 15 on the side of the slide plate 4 near the partition plate 2 and the locking bolt 8 provides a reliable fixing method. This design allows the rotating frame 7 to be firmly locked after the angle is adjusted. The threaded connection has a self-locking characteristic, which can effectively resist loosening caused by vibration. At the same time, the position design of the threaded hole 15 ensures that the operating space of the locking bolt 8 is sufficient, which is convenient for installation and disassembly.

[0021] As an optional technical solution of this utility model, a rotating hole 16 is provided through one side of the rotating frame 7. The rotating frame 7 is rotatably connected to the connecting rod 6 through the rotating hole 16. The depth of the rotating hole 16 is equal to the length of the connecting rod 6. The rotatable connection between the rotating hole 16 on the rotating frame 7 and the connecting rod 6 realizes the multi-angle adjustment of the display screen. The equal design of the depth of the rotating hole 16 and the length of the connecting rod 6 ensures the precise alignment of the rotation axis and eliminates the wobble phenomenon during rotation. This precise fit makes the angle adjustment of the display screen smoother and more accurate, while extending the service life of the rotating parts.

[0022] As an optional technical solution of this utility model, the top surface of the slide plate 4 is fixedly connected to two symmetrically arranged pads 17. The bottom surfaces of the two pads 17 are respectively attached to the bottom surfaces of the two rotating frames 7. The symmetrical pads 17 fixedly arranged on the top surface of the slide plate 4 provide a stable support platform for the rotating frames 7. The design of the two pads 17 being attached to the bottom surfaces of the two rotating frames 7 evenly distributes the weight load of the display screen and prevents local stress concentration. This support structure significantly improves the stability of the display screen after the angle is adjusted. At the same time, the material selection of the pads 17 takes wear resistance into consideration to ensure that no deformation will occur during long-term use.

[0023] As an optional technical solution of this utility model, two symmetrically arranged clamping plates 18 are fixedly connected to one side of the expansion frame 5, and two symmetrically arranged slots 19 are opened on both the left and right sides of the assembly frame 1. The clamping plates 18 are engaged with the assembly frame 1 through the slots 19. The engagement design of the symmetrical clamping plates 18 on one side of the expansion frame 5 with the slots 19 on the assembly frame 1 realizes the modular rapid expansion function. This symmetrically arranged engagement structure ensures balanced connection strength and can withstand large lateral loads. The elastic deformation design of the clamping plates 18 makes them easy to engage during installation, but requires specific operation to disengage during disassembly, which facilitates expansion and ensures safety during use.

[0024] A type of splicing LCD display screen works on the following principle: 1) When it is necessary to repair or replace the faulty LCD screen body 9, the staff can pull the locking lever 12 outward to move it out of the locking hole 13, which can release the lock on the slide plate 4.

[0025] 2): Pull the extension frame 4 outward to drive the slide plate 4 to slide outward along the guide rod 3 until the slide plate 4 moves to the appropriate position and the locking bolt 8 will be exposed. Remove the locking bolt 8 to lock the rotating frame 7.

[0026] 3): Pull the rotating frame 7 outward to make it rotate around the connecting rod 6 until the rotating frame 7 is perpendicular to the assembly frame 1. Then the locking part on the back of the LCD screen body 9 will be exposed, making it easy for the operator to use tools to disassemble the LCD screen body 9.

[0027] In summary, when the faulty LCD screen body 9 needs to be repaired or replaced, the operator can pull the locking rod 12 outward to move it out of the locking hole 13, which can release the lock on the slide plate 4. Pulling the extension frame 4 outward will cause the slide plate 4 to slide outward along the guide rod 3 until the slide plate 4 moves to the appropriate position, at which point the locking bolt 8 will be exposed. The locking bolt 8 can be removed to lock the rotating frame 7. At this time, pulling the rotating frame 7 outward will cause it to rotate around the connecting rod 6 until the rotating frame 7 is perpendicular to the splicing frame 1. The locking component on the back of the LCD screen body 9 will be exposed, making it easy for the operator to disassemble the LCD screen body 9 with tools, which greatly improves the replacement efficiency of the LCD screen body 9.
