Description

Technical Field

[0001] This utility model relates to the field of outdoor display screen bracket technology, and in particular to a multi-directional splicing structure for an outdoor display screen bracket. Background Technology

[0002] As a crucial support structure for LED displays, the stability and splicing accuracy of outdoor display brackets directly impact the overall effect and lifespan of the display. With the increasing demand for large displays in outdoor advertising, stadiums, and other scenarios, multi-screen splicing technology has become a key focus in the industry.

[0003] Currently, common outdoor display screen bracket splicing methods on the market include bolt fixing and welding connection. Plug-in connection method is also gradually becoming more popular. Bolt fixing and welding fixing methods use bolts or welding to fasten adjacent bracket units together. Although the connection is strong, the installation and welding are time-consuming and the disassembly is difficult, making it difficult to adjust later. The existing plug-in connection method achieves quick installation between bracket units by simply plugging and unplugging. However, this method has low installation accuracy due to the large gap between the plug and unplug slots, resulting in poor display effect after splicing multiple screens. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-directional splicing structure for an outdoor display screen bracket, aiming to improve the problems of time-consuming installation and difficult disassembly caused by the use of bolts or welding for splicing of existing display screen brackets, and poor screen display effect due to the low splicing accuracy of existing plug-in connections.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-directional splicing structure for an outdoor display screen bracket, comprising multiple splicing brackets, connecting plates, and screens. The outer wall of each splicing bracket has multiple splicing slots extending through it. The inner wall of each splicing bracket is fixedly connected to multiple splicing plates. The outer wall of each splicing plate has multiple locking holes extending through it. The inner wall of each connecting plate is provided with multiple engaging springs. The inner wall of each connecting plate is slidably connected with multiple locking blocks. The inner wall of each splicing bracket is provided with multiple unlocking components. The outer wall of each splicing bracket is provided with multiple screen connecting components.

[0006] The above technical solution involves: rapidly splicing multiple splicing brackets and connecting plates; displaying content by splicing multiple screens onto the brackets; fixing the connecting plates by inserting them into the slots through splicing grooves on the outer walls of the splicing brackets; locking the locking blocks that slide inside the connecting plates through multiple locking holes on the inner walls of the splicing plates; allowing the locking blocks to be disassembled and reset at any time through locking springs; finally disassembling the brackets through unlocking components; and installing the screens onto the brackets through screen connection components.

[0007] As a further description of the above technical solution:

[0008] Preferably, the screen connection assembly includes a connecting block, which is fixedly connected to the outer wall of the splicing bracket. The inner wall of the connecting block is slidably connected to a locking plate, a limiting block, and a slider. The bottom end of the limiting block is fixedly connected to a pull rod. The inner wall of the connecting block is provided with a spring and a spring. The inner wall of the connecting block is rotatably connected to a buckle. The outer wall of the buckle is fixedly connected to a functional block.

[0009] The above technical solution involves using connecting blocks to protect internal components, using fixed connections to allow the connecting blocks to be assembled with the bracket to provide mounting slots for the screen, using a snap-fit ​​plate to install at the bottom of the screen, using clips to snap the snap-fit ​​plate in place, and using a pulling rod to release the clips from the snap-fit ​​plate for easy disassembly.

[0010] As a further description of the above technical solution:

[0011] Preferably, the unlocking component includes multiple sliding plates, which are slidably connected to the inner wall of the splicing bracket. A rack is fixedly connected to the outer wall of the sliding plate, a gear is rotatably connected to the inner wall of the splicing bracket, and multiple top posts are fixedly connected to the outer wall of the sliding plate. A toggle rod is fixedly connected to the outer wall of one of the sliding plates, and multiple limiting pads are penetrated and fixedly connected to the outer wall of the splicing bracket. The toggle rod is slidably connected to the inner wall of the limiting pad.

[0012] The above technical solution involves limiting the sliding of the slide plate by using a splicing bracket, driving the slide plate to slide by using a toggle lever, pushing the locking block to disengage from the locking hole by multiple top pins on the slide plate, and preventing the toggle lever from sliding freely by using the friction of the limiting pad.

[0013] As a further description of the above technical solution:

[0014] Preferably, the two splicing brackets are slidably connected on their adjacent sides, the connecting plate is slidably connected to the inner wall of the two adjacent splicing brackets, the connecting plate is slidably connected to the inner wall of the splicing groove, and the connecting plate is slidably connected to the outer wall of the splicing plate.

[0015] The above technical solution involves fixing the splicing plate by inserting a connecting plate into the splicing groove on the inner wall of a splicing bracket, and installing the splicing groove of another splicing bracket by aligning it with the outer wall of the connecting plate, so that the outer walls of the two splicing brackets fit together, thus completing the splicing of the two brackets.

[0016] As a further description of the above technical solution:

[0017] Preferably, one end of the engaging spring is fixedly connected to the inner wall of the connecting plate, the other end of the engaging spring is fixedly connected to the outer wall of the locking block, the locking block is slidably connected to the outer wall of the splicing plate, and the locking block is slidably connected to the inner wall of the locking hole.

[0018] The above technical solution uses a snap-fit ​​spring to connect the connecting plate and the locking block. The locking block slides on the outer wall of the splicing plate to squeeze the snap-fit ​​spring, so that the locking block can be ejected by the stress of the snap-fit ​​spring after it reaches the locking hole.

[0019] As a further description of the above technical solution:

[0020] Preferably, the locking plate is fixedly connected to the bottom end of the screen, the bottom end of the locking plate is slidably connected to the top end of the buckle, the outer wall of the locking plate has a locking groove that extends through it, and the outer wall of the buckle is slidably connected to the inner wall of the locking groove.

[0021] The above technical solution involves installing locking plates at the four corners of the bottom of the screen, and then securing the locking plates by snapping them into their locking slots.

[0022] As a further description of the above technical solution:

[0023] Preferably, one end of the first spring is fixedly connected to the inner wall of the connecting block, and the other end of the first spring is fixedly connected to the outer wall of the slider. One end of the second spring is fixedly connected to the inner wall of the connecting block, and the other end of the second spring is fixedly connected to the outer wall of the functional block.

[0024] The above technical solution allows the slider to be connected to the inner wall of the connecting block using spring one, and it can slide and reset flexibly. Spring two connects the functional block and the connecting block, and the stress of the spring allows the slider and the functional block to reset after being squeezed.

[0025] As a further description of the above technical solution:

[0026] Preferably, the teeth of the rack and gear are meshed together, the outer wall of the top connecting post and the outer wall of the locking block are slidably connected, and the outer wall of the top connecting post and the inner wall of the locking hole are slidably connected.

[0027] The above technical solution involves the meshing of two racks and a middle gear. When one rack is driven to slide, the gear can drive the other rack to slide in opposite directions, thereby driving multiple top pins to push the locking block, causing the locking block to disengage from the locking hole, thus releasing the splicing of the connecting plate and the splicing bracket.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, multiple splicing slots are evenly opened on the outer walls of the splicing bracket, and connecting blocks are simultaneously engaged in two splicing slots of adjacent splicing brackets to achieve rapid splicing of the splicing bracket in all directions. High-precision splicing of the splicing plate is achieved by engaging locking blocks and locking holes.

[0030] 2. In this utility model, multiple locking plates are installed at the four corners of the bottom of the screen. The locking plates are then installed into the connecting blocks with buckles. The buckles lock the locking slots of the locking plates, thus completing the quick installation of the screen. The spring elasticity of the connecting blocks can be used to adjust the angle to a certain extent.

[0031] 3. In this utility model, by sliding the pull rod in the limiting pad, the slide plate is driven to slide synchronously. Through the meshing of the gear rack, the slide plate on the other side is driven to slide towards each other. By the top pins on multiple slide plates simultaneously squeezing the locking block to disengage from the locking hole, the quick disassembly between the brackets is realized.

[0042] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] Reference Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a multi-directional splicing structure for an outdoor display screen bracket, comprising multiple splicing brackets 1, connecting plates 2, and screens 5. The outer wall of the splicing bracket 1 has multiple splicing slots 101 that extend through it. The inner wall of the splicing bracket 1 is fixedly connected to multiple splicing plates 102. The outer wall of the splicing plates 102 has multiple locking holes 103 that extend through it. The inner wall of the connecting plates 2 is provided with multiple locking springs 201. The inner wall of the connecting plates 2 is slidably connected with multiple locking blocks 202. The inner wall of the splicing bracket 1 is provided with multiple unlocking components 3. The outer wall of the splicing bracket 1 is provided with multiple screen connecting components 4.

[0044] Specifically, the splicing structure has multiple splicing brackets 1, connecting plates 2, and screens 5. Multiple splicing slots 101 are provided around the outer wall of the splicing bracket 1, so that the other splicing brackets 1 can be quickly spliced ​​from the front, back, left, and right sides of the splicing bracket 1 through the connecting plates 2. During splicing, the connecting plates 2 are spliced ​​into the splicing slots 101 of the splicing bracket 1, so that the locking blocks 202 of the connecting plates 2 are engaged into the locking holes 103 of the splicing plates 102 on the inner wall of the splicing bracket 1, so that the multiple splicing brackets 1 are engaged. The unlocking component 3 is used to release the engagement to complete the subsequent disassembly. After the splicing is completed, the screen connecting component 4 is used to install the multiple screens 5 on the spliced ​​bracket.

[0045] Reference Figure 2 , Figure 3 and Figure 8 The screen connection assembly 4 includes a connecting block 401, which is fixedly connected to the outer wall of the splicing bracket 1. A locking plate 402, a limiting block 404, and a slider 406 are slidably connected to the inner wall of the connecting block 401. A pull rod 405 is fixedly connected to the bottom end of the limiting block 404. A spring 407 and a spring 410 are provided on the inner wall of the connecting block 401. A buckle 408 is rotatably connected to the inner wall of the connecting block 401. A functional block 409 is fixedly connected to the outer wall of the buckle 408. The locking plate 402 is fixedly connected to the screen... At the bottom of screen 5, the bottom of the locking plate 402 is slidably connected to the top of the buckle 408. The outer wall of the locking plate 402 has a locking groove 403 that extends through it. The outer wall of the buckle 408 is slidably connected to the inner wall of the locking groove 403. One end of spring 1 407 is fixedly connected to the inner wall of the connecting block 401. The other end of spring 1 407 is fixedly connected to the outer wall of the slider 406. One end of spring 2 410 is fixedly connected to the inner wall of the connecting block 401. The other end of spring 2 410 is fixedly connected to the outer wall of the functional block 409.

[0046] Specifically, after the bracket is assembled, the four corners of the screen 5 are fitted with locking plates 402, and the four connecting blocks 401 on the outer wall of the splicing bracket 1 are aligned. This allows the locking plates 402 to slide downwards along the inner wall of the connecting blocks 401. As the locking plates 402 slide downwards, their bottom ends slide along the top of the buckles 408, pushing the buckles 408 to rotate counterclockwise around the rotation point. During the rotation of the buckles 408, the functional block 409 fixed at its bottom end slides down and compresses the second spring 410. As the locking plates 402 continue to slide downwards, their bottom ends compress the slider 406 and the first spring 407, allowing them to continue sliding. When the locking groove 403 of the locking plates 402 slides past the tip of the buckles 408, the locking plates 402 engage. Under the stress of spring 410, buckle 408 resets and engages with the inner wall of engagement groove 403. After releasing the hand, engagement plate 402 will also be firmly engaged between the tip of buckle 408 and the top of slider 406 under the stress of spring 407. Thus, the four corners of screen 5 are engaged inside the four screen connection components 4 of splicing bracket 1. The angle can be adjusted by the elastic force of spring 407 and spring 410. When disassembly is required, pull rod 405 needs to be pulled down manually to make it drive limit block 404 to slide down synchronously, thereby squeezing buckle 408 and making it rotate counterclockwise. The tip will disengage from engagement with engagement plate 402 and screen 5 can be pulled out.

[0047] Reference Figure 4 , Figure 6 and Figure 7The unlocking component 3 includes multiple sliding plates 301, which are slidably connected to the inner wall of the splicing bracket 1. A rack 302 is fixedly connected to the outer wall of the sliding plate 301. A gear 303 is rotatably connected to the inner wall of the splicing bracket 1. Multiple top posts 304 are fixedly connected to the outer wall of the sliding plate 301. A toggle lever 305 is fixedly connected to the outer wall of one of the sliding plates 301. Multiple limiting pads 306 are passed through and fixedly connected to the outer wall of the splicing bracket 1. The toggle lever 305 is slidably connected to the inner wall of the limiting pad 306. The teeth of the rack 302 and the gear 303 are meshed. The outer wall of the top post 304 is slidably connected to the outer wall of the locking block 202. The outer wall of the top post 304 is slidably connected to the inner wall of the locking hole 103.

[0048] Specifically, when disassembling multiple splicing brackets 1, the actuating lever 305 is moved, causing it to slide against the inner wall of the limiting pad 306. The limiting pad 306 is made of soft rubber and is shaped with larger ends and a narrower section on the right side. By default, the actuating lever 305 is located at the right end of the limiting pad 306 and is fixed using the friction of the rubber. When unlocking is required, the actuating lever 305 needs to be moved to slide over the narrow section of the limiting pad 306. By squeezing the rubber, it can be moved over the narrow section and continue sliding to the left. Then, it is connected to the rack and pinion mechanism. The meshing connection between gear 302 and gear 303 allows one of the slide plates 301 to slide when the lever 305 is turned to move it. This slide plate 301 can then drive the rack 302 to slide. Through meshing, the gear 303 on the opposite side slides, which in turn drives the rack 302 on the opposite side to slide. This causes the racks 302 on both sides to slide towards each other. Multiple top posts 304 fixedly connected to the rack 302 push the locking block 202 out of the locking hole 103, thereby causing the connecting plate 2 to disengage from the splicing bracket 1 and achieving the purpose of disassembly.

[0049] Reference Figure 2 , Figure 4 and Figure 5 Two splicing brackets 1 are slidably connected on their adjacent sides, and a connecting plate 2 is slidably connected to the inner wall of the two adjacent splicing brackets 1. The connecting plate 2 is slidably connected to the inner wall of the splicing groove 101 and the outer wall of the splicing plate 102.

[0050] Specifically, before splicing, the sides of the two splicing brackets 1 need to be aligned. Multiple splicing brackets 1 are first engaged into the inner wall of the splicing groove 101 on one side of one of the splicing brackets 1. Then, the splicing groove 101 of the other splicing bracket 1 is actively engaged into the outer wall of the splicing bracket 1 to complete the splicing of the two splicing brackets 1.

[0051] Reference Figure 5One end of the engaging spring 201 is fixedly connected to the inner wall of the connecting plate 2, and the other end of the engaging spring 201 is fixedly connected to the outer wall of the locking block 202. The locking block 202 is slidably connected to the outer wall of the splicing plate 102 and the inner wall of the locking hole 103.

[0052] Specifically, the connecting plate 2 and the locking block 202 are connected by a snap-fit ​​spring 201. During the snap-fit ​​process, the locking block 202 will squeeze the snap-fit ​​spring 201. When it reaches the locking hole 103, the stress of the snap-fit ​​spring 201 will push the locking block 202 into the inner wall of the locking hole 103 to complete the snap-fit. The outer locking block 202 has a larger radius and the inner locking block 202 has a smaller radius. Correspondingly, the diameter of the right locking hole 103 is larger and the diameter of the left locking hole 103 is smaller, so that the outer locking block 202 will not snap into the left locking hole 103.

[0053] Working principle: When using this bracket splicing structure to install an outdoor display screen, align multiple splicing brackets 1 as required, insert one end of the connecting plate 2 into the splicing slot 101 of one splicing bracket 1, so that the locking block 202 on the connecting plate 2 slides along the surface of the splicing slot 101 and the splicing plate 102 while squeezing the locking spring 201, until the locking blocks 202 on both sides are engaged in the locking hole 103 and a locking sound is emitted. Then insert the other end of the connecting plate 2 into the splicing slot 101 of another splicing bracket 1 to complete the installation. Repeat this process multiple times until all splicing brackets 1 are spliced.

[0054] Next, install the locking plates 402 on the four corners of the bottom surface of the screen 5, align them with the slots of the multiple connecting blocks 401 on the splicing bracket 1 and press them down. This will cause the bottom end of the locking plate 402 to press the smooth top end of the buckle 408 and continue to slide until the bottom end of the locking plate 402 contacts the top end of the slider 406 and causes it to press the spring 407. After the buckle 408 is pressed for the first time, it will rotate counterclockwise. Its bottom end will cause the functional block 409 to press the spring 410. When the locking plate 402 continues to slide down, the buckle 408 will reset under the stress of the spring 410, and its tip will engage in the locking groove 403, fixing the locking plate 402 inside the connecting block 401. After that, release your hand to complete the installation of a single screen 5. Repeat this process multiple times until all screens 5 are spliced.

[0055] When disassembly is required after use, first pull the pull rod 405 at the bottom of the connecting block 401, so that it drives the limiting block 404 to press down the buckle 408 and the functional block 409 to compress the spring 410 together, so that the buckle 408 rotates and its tip disengages from the locking plate 402. At this time, the screen 5 and the locking plate 402 can be pulled out together. Repeat this several times until all screens 5 are removed.

[0056] Then, move the lever 305 to slide along the limiting pad 306 and squeeze past the narrow part of the outer wall of the limiting pad 306 and continue to slide, causing the slide plate 301 and rack 302 to slide, and causing the gear 303 to rotate. Through meshing, the opposite rack 302 and slide plate 301 slide towards each other, so that multiple top pins 304 on the two slide plates 301 simultaneously squeeze the locking block 202, causing it to disengage from the locking hole 103. Then the connecting plate 2 can be pulled out from the splicing slot 101 of the splicing bracket 1. Repeat this process multiple times until all splicing brackets 1 are disassembled.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
