Description

Technical Field

[0001] The utility model relates to the technical field of splicing screens, in particular to a fixing device for a splicing screen. Background Art

[0002] A splicing screen is a display technology that physically combines multiple display screens to form a large screen. This technology is usually used in occasions that require displaying a large amount of information or providing high-resolution visual effects, such as control room monitoring, conference displays, billboards, stage backgrounds, etc. When splicing multiple display screens together, a fixing device is usually required to assist in connecting the multiple display screens together.

[0003] After some existing fixing devices splice multiple display screens together, it is easy for a single display screen to be damaged. At this time, it is necessary to remove all the multiple display screens around this display screen, which is rather troublesome. And for such fixing devices, after splicing multiple display screens together, the protruding ends of the fixing plates in the edge area are exposed outside, affecting the viewing experience of this display screen.

[0004] Therefore, the technical personnel in this field provide a fixing device for a splicing screen to solve the problems raised in the above background art. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a fixing device for a splicing screen is proposed. By setting an L-shaped block and an L-shaped groove, it can horizontally and vertically splice multiple splicing screen bodies, and can disassemble a single splicing screen body from the front and back, which is more convenient. By setting a flipping mechanism, the L-shaped block on one side can be flipped over to avoid affecting the viewing experience.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A fixing device for a splicing screen, including a splicing screen body, a connecting block, a fixing mechanism, and two flipping mechanisms. The fixing mechanism includes a fixing plate, two first sliding grooves, two sliders, a second sliding groove, a rotating rod, a fixing ring, two connecting ropes, and a square block. L-shaped grooves are respectively opened at the rear side and the middle position of the lower side of one end face of the fixing plate. First return springs are respectively fixedly arranged between the two sliders and the two first sliding grooves;

[0007] A second return spring is fixedly arranged between the square block and the second sliding groove. A first cylinder is fixedly arranged at the middle position of the upper side of one end face of the square block. A second cylinder is fixedly arranged on one end face of the square block close to the first cylinder. The two flipping mechanisms include two U-shaped plates, two rotating blocks, two sliding holes, and two third cylinders. L-shaped blocks are fixedly arranged at one ends of the two rotating blocks.

[0008] Through the above technical solution, by rotating the rotating rods on the surfaces of multiple fixing plates respectively, before rotating the rotating rods, while pressing the second cylinder into the fixing plate, hold the rotating rod and rotate it counterclockwise. When rotation is no longer possible, release the pushing force on the second cylinder. During the rotation of the rotating rod, the rotating rod drives the connecting rope to deform through two fixing rings, and the deformed connecting rope drives the slider to move. During the movement of the slider, the third cylinder threadedly connected to it is driven to move together. At this time, the protruding end of the third cylinder enters the interior of the L-shaped block, and then the L-shaped block is pushed into the L-shaped groove opened in another fixing plate. When splicing multiple splicing screen bodies horizontally and vertically, while pushing the second cylinder into the fixing plate, turn the rotating rod back. After splicing multiple splicing screen bodies, manually rotate the third cylinder at the edge so that the third cylinder leaves the interior of the slider. At this time, the L-shaped block can be rotated, so that the L-shaped block is located inside the fixing plate, avoiding the L-shaped block from affecting the viewing experience.

[0009] Further, one end of the connecting block is fixedly connected to the splicing screen body, and the other end of the connecting block is fixedly connected to the fixing plate through four bolts;

[0010] Through the above technical solution, by rotating the four bolts, the splicing screen body can be separated from the fixing plate.

[0011] Further, the two first sliding grooves are respectively opened at the middle positions of the upper end face and the front end face of the fixing plate, and the two sliders are respectively slidably arranged inside the two first sliding grooves;

[0012] Through the above technical solution, the sliders are limited by the first sliding grooves, so that the two sliders inside one fixing plate can only move horizontally and vertically.

[0013] Further, the second sliding groove is opened at a corner of the inner wall of the fixing plate, and the square block is slidably arranged on one side inside the second sliding groove;

[0014] Through the above technical solution, the square block is limited by the second sliding groove, so that the square block can only move horizontally inside the fixing plate.

[0015] Further, the rotating rod is rotatably arranged through a corner of one side end face of the fixing plate, the fixing ring is fixedly sleeved at the middle position of the outer end face of the rotating rod, and the two sliders are respectively connected to the fixing ring through connecting ropes;

[0016] Through the above technical solution, when rotating the rotating rod, the fixing ring on the surface of the rotating rod is driven to rotate, which can drive the two connecting ropes connected to the fixing ring to deform, thereby driving the two sliders to move.

[0017] Further, the two U-shaped plates are respectively fixedly arranged at the front side and the middle position on the upper side of one end of the fixed plate, and the two rotating blocks are respectively rotatably arranged between the inner top surface and the inner bottom surface of the two U-shaped plates;

[0018] Through the above technical solution, the rotating blocks are supported by the U-shaped plates, enabling the rotating blocks to rotate.

[0019] Further, the two sliding holes are respectively opened at one end of the two L-shaped blocks, the two third cylinders are respectively slidably arranged inside the two sliding holes, and one ends of the two third cylinders are respectively threadedly connected to one ends of the two sliders;

[0020] Through the above technical solution, when the third cylinders are rotated out of the inside of the sliders, the fixation of the L-shaped blocks can be released. At this time, the L-shaped blocks can be held and rotated, and the third cylinders are supported by the sliding holes, keeping the third cylinders always inside the L-shaped blocks.

[0021] The utility model has the following beneficial effects:

[0022] 1. For a fixing device for a splicing screen proposed by the utility model, by pushing the second cylinder into the fixed plate while holding the rotating rod and rotating it counterclockwise, and when it can no longer rotate, releasing the extrusion of the second cylinder. During the rotation of the rotating rod, the two connecting ropes are deformed by the fixing ring, driving the two sliders to move. At this time, the L-shaped block of this fixed plate can be pushed into the L-shaped groove of another fixed plate. After splicing multiple splicing screen bodies together, while continuing to push the second cylinder into the fixed plate, the rotating rod is rotated back to its original position. At this time, multiple splicing screen bodies can be spliced horizontally and vertically, and a single splicing screen body can be disassembled from the front and back, which is more convenient.

[0023] 2. For a fixing device for a splicing screen proposed by the utility model, after splicing multiple splicing screen bodies together, the third cylinders at the edge positions can be rotated respectively. At this time, the third cylinders leave the inside of the sliders, and then the L-shaped blocks connected to the third cylinders are held and rotated so that the L-shaped blocks are blocked by the fixed plate. Then the same operation is performed on multiple L-shaped blocks in sequence. At this time, multiple L-shaped blocks are blocked by the fixed plate, improving the viewing experience.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figures 1-6, an embodiment provided by the present utility model: a fixing device for a splicing screen, including a splicing screen body 1, a connecting block 2, a fixing mechanism 3 and two flipping mechanisms 4. The fixing mechanism 3 includes a fixing plate 301, two first sliding grooves 303, two sliders 304, a second sliding groove 306, a rotating rod 307, a fixing ring 308, two connecting ropes 309 and a square block 310. L-shaped grooves 302 are respectively formed at the rear side and the middle position of the lower side of one side end face of the fixing plate 301. First return springs 305 are respectively fixedly arranged between the two sliders 304 and the two first sliding grooves 303. A second return spring 311 is fixedly arranged between the square block 310 and the second sliding groove 306. A first cylinder 312 is fixedly arranged at the middle position of the upper side of one side end face of the square block 310. A second cylinder 313 is fixedly arranged on one side end face of the square block 310 close to the first cylinder 312. The two flipping mechanisms 4 include two U-shaped plates 401, two rotating blocks 402, two sliding holes 404 and two third cylinders 405. The two first sliding grooves 303 are respectively formed at the middle positions of the upper end face and the front side end face of the fixing plate 301. The two sliders 304 are respectively slidably arranged inside the two first sliding grooves 303.

[0034] The second sliding groove 306 is formed at a corner of the inner wall of the fixing plate 301. The square block 310 is slidably arranged at one side inside the second sliding groove 306. The rotating rod 307 is rotatably arranged through one side end face corner of the fixing plate 301. The fixing ring 308 is fixedly sleeved at the middle position of the outer end face of the rotating rod 307. The two sliders 304 are respectively connected with the fixing ring 308 through the connecting ropes 309. Before splicing the splicing screen body 1, by respectively rotating the rotating rods 307 on the surfaces of multiple fixing plates 301, before rotating the rotating rod 307, the second cylinder 313 should be pressed into the fixing plate 301 while holding the rotating rod 307 and rotating it counterclockwise. When pressing the second cylinder 313, the second cylinder 313 drives the square block 310 to move together, so that the first cylinder 312 leaves the inside of the fixing ring 308. When rotation is no longer possible, the convex block on the surface of the fixing ring 308 abuts against the convex block on the surface of the square block 310, thereby reminding the operator to release the pushing of the second cylinder 313 at this time. During the rotation of the rotating rod 307, the rotating rod 307 drives the connecting ropes 309 to deform through the two fixing rings 308, and the deformed connecting ropes 309 drive the sliders 304 to move.

[0035] During the movement of the slider 304, the third cylinder 405 threadedly connected thereto is driven to move together. At this time, the protruding end of the third cylinder 405 enters the inside of the L-shaped block 403, and then the L-shaped block 403 is pushed into the L-shaped groove 302 opened in another fixing plate 301. When splicing a plurality of splicing screen bodies 1 horizontally and vertically, while pushing the second cylinder 313 into the fixing plate 301, the rotating rod 307 is turned back. After the rotating rod 307 is turned back, by the resilience of the first return spring 305, the third cylinder 405 can be pushed into the inside of another L-shaped groove 302 through the slider 304, so as to splice two splicing screen bodies 1 together. L-shaped blocks 403 are fixedly provided at one ends of two rotating blocks 402. Two U-shaped plates 401 are respectively fixedly provided at the front side and the middle position on the upper side of one side end of the fixing plate 301. The two rotating blocks 402 are respectively rotatably provided between the inner top surface and the inner bottom surface of the two U-shaped plates 401. Two sliding holes 404 are respectively opened at one ends of the two L-shaped blocks 403. Two third cylinders 405 are respectively slidably provided inside the two sliding holes 404. One ends of the two third cylinders 405 are respectively threadedly connected to one ends of the two sliders 304.

[0036] After splicing a plurality of splicing screen bodies 1, manually rotate the third cylinder 405 at the edge to make the third cylinder 405 leave the inside of the slider 304. At this time, the L-shaped block 403 can be rotated, so that the L-shaped block 403 is located inside the fixing plate 301, avoiding the influence of the L-shaped block 403 on the viewing experience. One end of the connecting block 2 is fixedly connected to the splicing screen body 1, and the other end of the connecting block 2 is fixedly connected to the fixing plate 301 through four bolts. By rotating the four bolts, the splicing screen body 1 can be separated from the fixing plate 301. When a single splicing screen body 1 is damaged, the second cylinder 313 can be pushed into the fixing plate 301 while rotating the rotating rod 307 counterclockwise. When it can no longer be rotated, release the extrusion of the second cylinder 313, and then perform the same operation on the two fixing plates 301 adjacent to the L-shaped block 403 on the surface of the fixing plate 301, and then the fixing plate 301 can be taken out horizontally, without removing all the spliced splicing screen bodies 1, which is more convenient.

[0037] Working principle: While pushing the second cylinder 313 into the fixed plate 301, hold the rotating rod 307 and rotate it counterclockwise. When it can no longer rotate, release the extrusion on the second cylinder 313, and then perform the same operation on the remaining fixed plates 301. At this time, the L-shaped block 403 on the surface of the fixed plate 301 can be pushed into the L-shaped groove 302 opened in another fixed plate 301. After multiple splicing screen bodies 1 are spliced together, continue to push the second cylinder 313 into the fixed plate 301 while holding the rotating rod 307 and rotating it clockwise back. When multiple splicing screen bodies 1 are spliced together, manually rotate the third cylinder 405 at the edge, and then rotate the L-shaped block 403 connected to the third cylinder 405, so that multiple L-shaped blocks 403 are blocked by the fixed plate 301.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
