Description

Technical Field

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

[0002] In recent years, display technology has developed rapidly, and the application scenarios of displays have become increasingly widespread and complex, gradually expanding from traditional flat display needs to diverse irregular-shaped display fields. Among them, the market demand for curved splicing displays such as arc surfaces, elliptical arc surfaces, and wavy surfaces has shown a significant growth trend.

[0003] However, existing technologies, such as Chinese Publication No. CN215068972U, describe an inner-curve splicing display screen, which includes multiple splicing cabinets, splicing light panels, and splicing connecting pieces. The splicing light panels are fixed to the splicing cabinets. Each of the four corners of the front of the splicing cabinet has a splicing platform with a first positioning post and a first screw hole. Correspondingly, the splicing connecting pieces have a first positioning hole and a second screw hole. The bottom surface of the splicing connecting pieces has an inner curvature. Half of the splicing connecting piece is fixed to the splicing platform of one splicing cabinet by screws, and the other half is fixed to the splicing platform of an adjacent splicing cabinet by screws. The first positioning post on the splicing platform is inserted into the first positioning hole on the splicing connecting piece, thereby forming an inner curvature between adjacent splicing cabinets. This splicing method offers structural stability, reliable fixing, convenient assembly, and small and easily controllable splicing gaps. When different inner curvatures are required, only the corresponding splicing connecting pieces need to be replaced; the splicing cabinets and splicing light panels do not need to be changed.

[0004] However, during the use of this device, it was found that although the instructions stated that the inner arc could be adjusted simply by replacing the corresponding splicing connecting piece, in practice, multiple arc connecting pieces needed to be prepared in advance, increasing inventory costs. Moreover, replacing the connecting piece on-site required disassembling multiple screws, which was time-consuming and unsuitable for rapid adjustment needs. On the other hand, the first positioning post on the splicing platform and the first positioning hole of the splicing connecting piece needed to be precisely matched. However, in actual production, the positional tolerances of the positioning posts of multiple splicing boxes may accumulate, resulting in an uneven overall arc or uneven splicing gaps after splicing. If the gap between the positioning post and the positioning hole is too small, it will lead to assembly difficulties; if the gap between the positioning post and the positioning hole is too large, it will reduce the splicing stability and easily cause loosening. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology that require preparing connecting pieces with various curvatures when adjusting the inner arc, which increases inventory costs, and that certain tolerances will be generated after splicing the positioning post and positioning hole, which will have a certain impact on subsequent installation steps.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an arc splicing display screen, comprising: a bidirectional lead screw; two sets of connecting arms, respectively disposed at both ends of the bidirectional lead screw; an arc-shaped connecting plate rotatably connected to the end of the connecting arm; a mounting plate movably disposed on one side of the arc-shaped connecting plate; and a reinforcing member disposed on the back of the arc-shaped connecting plate, one end of which is fixed to the wall.

[0007] The technical effect of adopting the above-mentioned further solution is that the two sets of connecting arms are driven by the bidirectional lead screw, which makes the arc-shaped connecting plate rotate. With the help of the movable mounting plate, the curvature of the display screen can be adjusted. The back reinforcement is fixed to the wall, realizing multi-angle arc splicing and stable installation of the display screen, meeting the arc display needs of different scenarios.

[0008] In a preferred embodiment, the arc-shaped connecting plate and the mounting plate are movably connected by a quick-connect fitting, which includes: a limiting tenon, welded to the end face of the arc-shaped connecting plate; and a mounting mortise, located on one side of the mounting plate and cooperating with the limiting tenon.

[0009] The technical effect of adopting the above-mentioned further solution is that the arc-shaped connecting plate and the mounting plate are connected by a quick-connect fitting. The quick-connect fitting includes a limiting tenon welded to the cross-section of the arc-shaped connecting plate and a mounting tenon groove on one side of the mounting plate that mates with the limiting tenon. This allows for quick installation and disassembly of the two, improving the efficiency of display assembly and the convenience of maintenance.

[0010] In a preferred embodiment, the reinforcement includes: a fixed stud, one end of which is fixedly connected to the end face of the arc-shaped connecting plate; a movable sleeve, threadedly engaged with the outside of the fixed stud; and a fixing block, fixedly connected to one end of the movable sleeve, one side of which is provided with an anti-slip surface; wherein the fixing block is fixedly connected to the mounting wall.

[0011] The technical advantage of adopting the above-mentioned further solution is that: the curved connecting plate is connected by a fixed stud, the external movable sleeve is threadedly engaged with the fixed stud, and one end of the sleeve is fixed to the wall with an anti-slip surface. By adjusting the position of the sleeve on the stud, the angle of the curved connecting plate can be finely adjusted and the installation can be securely completed, ensuring the structural stability and installation accuracy of the spliced ​​display screen.

[0012] In a preferred embodiment, the upper end face of the arc-shaped connecting plate and the mounting plate is provided with a plurality of through holes running longitudinally through each of the through holes, and a pin is provided in each of the through holes.

[0013] The technical effect of adopting the above-mentioned further solution is that: the upper end face of the arc-shaped connecting plate and the mounting plate is provided with several through holes in the longitudinal direction, and the pins are installed in the holes to connect the two, thereby avoiding relative displacement between the two and improving the stability of the device.

[0014] In a preferred embodiment, a reinforcing plate is fixedly connected to the lower end of the mounting plate, and a plurality of sets of first fixing bolts are provided on the reinforcing plate.

[0015] The technical advantage of adopting the above-mentioned further solution is that the reinforcing plate can be fixedly connected to the display module by bolts.

[0016] In a preferred embodiment, the end of the connecting arm is rotatably connected to a rotating shaft, and one end of the arc-shaped connecting plate is fixedly connected to the rotating shaft, allowing it to rotate around the central axis of the rotating shaft.

[0017] The technical effect of adopting the above-mentioned further solution is that the arc-shaped connecting plate can flexibly adjust the rotation angle, and in conjunction with the bidirectional screw to drive the connecting arm to move, it can achieve precise adjustment of the arc of the display screen, meet different splicing arc requirements, and improve the flexibility and applicability of the device.

[0018] In a preferred embodiment, a fixing frame is provided on the bidirectional lead screw, and a plurality of second fixing bolts are provided on the fixing frame to limit the displacement of the bidirectional lead screw on the wall; wherein, the connecting arm is engaged therein, allowing the connecting arm to move up and down along the bidirectional lead screw.

[0019] The technical effect of adopting the above-mentioned further solution is that this structure not only ensures the stable installation of the bidirectional lead screw, but also allows the connecting arm to move along the lead screw, thereby achieving stability and flexibility in the arc splicing of the display screen.

[0020] In a preferred embodiment, a rotating wheel is fixedly connected to the upper end of the bidirectional lead screw.

[0021] The technical effect of adopting the above-mentioned further solution is that rotating the wheel can drive the bidirectional lead screw to rotate, thereby driving the connecting arms at both ends to move up and down along the lead screw, so as to realize the angle adjustment of the arc-shaped connecting plate.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. This utility model uses a bidirectional lead screw to drive two sets of connecting arms to move synchronously in opposite directions, causing the arc-shaped connecting plate to rotate around the axis. Compared with the prior art, there is no need to prepare connecting plates of various specifications for different curvature requirements. The target angle can be adjusted simply by rotating the wheel, which significantly reduces the types and quantities of spare parts and lowers inventory management costs.

[0024] 2. This utility model adopts a dovetail quick-connect structure with a limiting tenon and an installation tenon groove, and is locked with a pin shaft. This effectively solves the problem of tolerance accumulation caused by the splicing of traditional positioning posts and positioning holes, reduces the curvature deviation of the whole screen after splicing multiple modules, and improves the efficiency of subsequent installation steps and the consistency of display effect.

[0033] The bidirectional lead screw 1 has two ends connected to two sets of connecting arms 2 via threaded pairs to form a transmission connection. When the lead screw rotates, it drives the two sets of connecting arms 2 to make synchronous and opposite linear motion, so that the device can adapt to different sizes of display screens.

[0034] A rotating wheel 12 is fixedly installed at the top of the bidirectional lead screw 1 for manually driving the bidirectional lead screw 1 to rotate.

[0035] The middle part of the bidirectional lead screw 1 is fixed to the wall by a fixing bracket 13 and a second fixing bolt 14, which restricts its axial displacement and radial sway.

[0036] Connecting arm 2, the inner end of each connecting arm 2 is sleeved on the corresponding threaded section of the bidirectional lead screw 1 through a threaded pair, and the outer end is connected to the middle of the back of the arc-shaped connecting plate 4 through the rotating shaft 3 to form a rotating pair, so that the arc-shaped connecting plate 4 can be adjusted around the axis of the rotating shaft 3.

[0037] The arc-shaped connecting plate 4 has a limiting tenon 6 on its front side along the arc length direction. The limiting tenon 6 has a dovetail structure and is perpendicular to the front side of the arc-shaped connecting plate 4. Reinforcing parts are symmetrically provided at both ends of the back side.

[0038] Mounting plate 5 is used to fix the display module. Its back is provided with mounting groove 7 that matches the limiting tenon 6. It can slide and quickly connect with the arc-shaped connecting plate 4 through the tenon structure.

The fixing block 17 is fixed to the wall by expansion bolts, and a serrated anti-slip surface 18 is provided on the side that contacts the wall.

[0043] Working Principle: This device is a curved splicing display screen. In use, a set of connecting arms 2 are first set up by threaded engagement. The relative distance between the set of connecting arms 2 is adjusted according to the size of the display screen to be installed, so that the display screen and its components can be stably fixed. Then, the curved connecting plate 4 is installed on the connecting arms 2 through the rotating shaft 3. The device is fixed to the wall installation position by the second fixing bolt 14 on the fixing bracket 13. Then, the mounting plate 5 is installed with the display module by the reinforcing plate 10 on the mounting plate 5 and the first fixing bolt 11.
