Abstract
Description
Technical Field
[0001] This utility model relates to the field of EVA sheet technology, and in particular to an EVA sheet with a splicing structure. Background Technology
[0002] EVA is a new type of environmentally friendly plastic foam material with good cushioning, shock resistance, moisture resistance and corrosion resistance. EVA products can be processed into sheets, and their shock resistance is better than that of traditional foam materials, and they meet environmental protection requirements.
[0003] When splicing EVA sheets to form a complete floor or wall surface, the traditional method is to install splicing ears on both sides of the EVA sheet and make splicing holes on the other two sides of the EVA sheet to fit the splicing ears. Then, two EVA sheets are spliced together by connecting them one by one through the splicing ears and splicing holes. This method makes it easy for the splicing ears of the EVA sheet to deform under stress and become difficult to connect into the splicing holes. Furthermore, if you want to remove them later, you can easily damage the splicing ears, causing damage to the EVA sheet and making it inconvenient for reuse. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an EVA sheet with a splicing structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An EVA sheet with a splicing structure includes an EVA board and a first splicing block. The EVA board has a square structure, and splicing boards are fixedly connected around the EVA board. Two connecting blocks are fixedly connected to the side wall of each splicing board.
[0007] It also includes a splicing mechanism, which includes a first splicing block and a splicing groove. The first splicing block is a long strip-shaped mechanism. Splicing grooves are symmetrically opened on both sides of the first splicing block. The thickness of the splicing groove is the same as the thickness of the splicing plate. Connecting grooves are symmetrically opened on both sides of the splicing groove. A movable groove is opened inside the first splicing block. Two limiting grooves are symmetrically opened in the middle of the movable groove. A locking mechanism including a locking rod is provided in the movable groove. Two vertical actuating grooves are symmetrically opened in the middle of the top of the first splicing block. The bottom of the actuating groove is connected to the movable groove.
[0008] Preferably, the thickness of the splicing plate is less than that of the EVA plate, and the connecting block has through holes.
[0009] Preferably, the splicing mechanism further includes a second splicing block, which has the same structure as the first splicing block but is shorter in length, and the two end sidewalls of the second splicing block are fixedly connected with mating blocks.
[0010] Preferably, the thickness of the first splicing block and the second splicing block is the same as the thickness of the EVA board, and the size of the mating block is adapted to one end of the first splicing block.
[0011] Preferably, the two ends of the movable groove are respectively connected to two connecting grooves, and each connecting groove passes through the splicing grooves on both sides of the first splicing block.
[0012] Preferably, a fixed rod is fixedly installed at the center of the movable groove, and sliding rods are symmetrically sleeved at both ends of the fixed rod. A limiting ring that is slidably connected to the limiting groove is fixedly connected to one side of the sliding rod. An extension rod is fixedly connected to the end of the two sliding rods, and two locking rods are fixedly connected to both ends of the two extension rods.
[0013] Preferably, a lever block that is slidably connected to the lever is fixedly connected to one end of the sliding rod near the lever groove, and springs are fixedly connected to both sides of the fixed rod, with the ends of the springs fixedly connected to the side wall of the lever block.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This invention features an EVA board that is spliced together with splicing slots in a splicing mechanism via surrounding splicing plates. The continuous splicing plates are less prone to deformation or bending due to external forces during use, ensuring safety during splicing. The continuous splicing plates also improve the splicing effect and stability of the EVA board after splicing, preventing it from falling off after splicing.
[0016] This invention features a splicing mechanism that uses a first splicing block and a second splicing block in pairs. The first splicing block is used in the horizontal direction of the EVA board, while the second splicing block is used in the vertical direction. This facilitates the operator's work during splicing, eliminating the need for splicing ears and holes as in traditional splicing methods. The connecting groove is used to position the EVA board with the connecting block, making it easy to position and splice the EVA board with the splicing mechanism. This prevents deviations when splicing multiple EVA boards, which could cause subsequent splicing problems. Furthermore, the overall thickness of the spliced board is consistent, and the overall appearance is aesthetically pleasing.
[0017] This invention features a locking mechanism that locks two EVA boards together after they are joined to the splicing groove and the connecting block is also inserted into the groove. This prevents the EVA boards from falling off, ensuring a stable connection and effective coverage of the wall or floor. The mechanism is easy to use, requires no external tools, and allows for easy removal of the EVA boards without damaging them or affecting their reuse. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Reference Figure 1-6 An EVA sheet with a splicing structure includes an EVA board 1 and a first splicing block 6. The EVA board 1 has a square structure, and splicing boards 2 are fixedly connected around the EVA board 1. Two connecting blocks 3 are fixedly connected to the side wall of each splicing board 2.
[0027] It also includes a splicing mechanism 5, which includes a first splicing block 6 and a splicing groove 7. The first splicing block 6 is a long strip-shaped mechanism. The two side walls of the first splicing block 6 are symmetrically provided with splicing grooves 7. The thickness of the splicing groove 7 is the same as the thickness of the splicing plate 2. The two sides of the splicing groove 7 are symmetrically provided with connecting grooves 8. The first splicing block 6 has a movable groove 11 inside. The movable groove 11 has two symmetrically provided with limiting grooves in the middle. The movable groove 11 is provided with a locking mechanism 12 including a locking rod 17. The top center of the first splicing block 6 has two symmetrically provided with vertical actuating grooves 111. The bottom of the actuating grooves 111 is connected to the movable groove 11. EVA board 1 is spliced with splicing slots 7 of splicing mechanism 5 via splicing plates 2 around its perimeter. The continuous splicing plates 2 are less prone to deformation and bending due to external forces during use, ensuring safety during splicing of EVA board 1. The continuous splicing plates 2 also improve the splicing effect and stability of EVA board 1 after splicing, preventing detachment after splicing. The splicing mechanism 5 uses a first splicing block 6 and a second splicing block 9 in pairs. The first splicing block 6 is used in the horizontal direction of EVA board 1, and the second splicing block 9 is used in the vertical direction of EVA board 1. This facilitates the operator's operation during splicing, eliminating the need for splicing ears and splicing holes as in traditional splicing methods. Connecting slots 8 are used for... The connecting block 3 is used to position the EVA board 1, making it easy to position and splice the EVA board 1 with the splicing mechanism 5. This prevents deviations when splicing multiple EVA boards 1, which could cause subsequent splicing problems. After two EVA boards 1 are spliced into the splicing groove 7 and the connecting block 3 is connected into the connecting groove 8, the two EVA boards 1 can be locked by the locking mechanism 12 to prevent the EVA boards 1 from falling off. This ensures that the overall EVA board 1 connection is stable after splicing, ensuring the coverage effect on the wall or floor. If you want to remove the EVA board 1 later, you can also remove the EVA board 1 by unlocking the locking mechanism 12. The operation is convenient, will not damage the EVA board 1, and will not affect the secondary use of the EVA board 1.
[0028] As a technical optimization of this utility model, the thickness of the splicing plate 2 is less than that of the EVA plate 1, and the connecting block 3 has a through hole 4. The through hole 4 is used to insert the locking rod 17.
[0029] As a technical optimization of this utility model, the splicing mechanism 5 further includes a second splicing block 9. The second splicing block 9 has the same structure as the first splicing block 6 but is shorter in length than the first splicing block 6. The two end side walls of the second splicing block 9 are fixedly connected with mating blocks 10. The second splicing block 9 works in conjunction with the first splicing block 6 to splice the EVA board 1 in both horizontal and vertical directions.
[0030] As a technical optimization of this utility model, the thickness of the first splicing block 6 and the second splicing block 9 is the same as the thickness of the EVA board 1, and the size of the mating block 10 is adapted to one end of the first splicing block 6. After the splicing plate 2 is inserted into the splicing groove 7, the thickness of the EVA board 1 is the same as that of the first splicing block 6 and the second splicing block 9, so that the overall thickness after splicing is consistent and aesthetically pleasing. Since the first splicing block 6 and the second splicing block 9 are installed perpendicular to each other, the size of the mating block 10 can fill the gap between the two first splicing blocks 6, so that the connection between the first splicing block 6 and the second splicing block 9 is seamless, resulting in a flat overall surface.
[0031] As a technical optimization of this utility model, the two ends of the movable groove 11 are respectively connected to two connecting grooves 8, and each connecting groove 8 penetrates the splicing grooves 7 on both sides of the first splicing block 6. After the connecting block 3 is connected to the connecting groove 8, it is convenient for the locking rod 17 to be inserted into the through hole 4 to lock the EVA board 1.
[0032] As a technical optimization of this utility model, a fixed rod 13 is fixedly installed at the center of the movable groove 11. Sliding rods 14 are symmetrically sleeved at both ends of the fixed rod 13. A limiting ring 18, which is slidably connected to the limiting groove, is fixedly connected to one side of the sliding rod 14. Extension rods 16 are fixedly connected to the ends of the two sliding rods 14. Two locking rods 17 are fixedly connected to both ends of the two extension rods 16. The locking rods 17 are used to insert into the through hole 4. The locking rods 17 can be moved by pulling the sliding rods 14. The limiting ring 18 can limit the movement distance of the sliding rods 14.
[0033] As a technical optimization of this utility model, a lever 14 is fixedly connected to a lever block 15 that is slidably connected to the lever 111 at one end near the lever groove 111. Springs 19 are fixedly connected to both sides of the fixed rod 13, and the ends of the springs 19 are fixedly connected to the side walls of the lever block 15. Since the lever groove 111 and the lever block 15 are located in the middle of the first splicing block 6, the two levers 15 can be moved with one hand to overcome the pushing force of the springs 19, so that the two sliding rods 14 move closer to each other, thereby causing the locking rods 17 on both sides to disengage from the connecting groove 8 and retract into the movable groove 11. The connecting block 3 can then be connected into the connecting groove 8. After releasing the hand, the springs 19 return to their original position, which pushes the locking rods 17 to return to their original position and insert them into the through hole 4 to achieve locking. The operation is convenient and does not require external tools.
[0034] In use, when splicing in the horizontal direction, the first splicing block 6 is placed between two EVA boards 1. By moving two levers 15 with one hand to overcome the pushing force of the spring 19, the two sliding rods 14 are brought closer together, causing the locking rods 17 on both sides to disengage from the connecting groove 8 and retract into the movable groove 11. Pushing one EVA board 1 causes the splicing board 2 to enter the splicing groove 7 on one side, and simultaneously the connecting block 3 enters the connecting groove 8. Then, pushing the other EVA board 1 repeats the above operation, with the connecting block of the two EVA boards 1 connected... 3 are connected to the connecting slot 8. When the two levers 15 are released, the spring 19 will reset and push the locking rod 17 to reset and insert it into the through hole 4 to lock the two EVA boards 1. Similarly, when splicing in the vertical direction, the second splicing block 9 is placed between the two EVA boards 1. The operation is the same as that of the first splicing block 6 to complete the splicing. The overall thickness after splicing is consistent and the overall appearance is beautiful. Since the first splicing block 6 and the second splicing block 9 are installed perpendicular to each other, the size of the mating block 10 can make up for the gap between the two first splicing blocks 6.
[0035] When removing EVA board 1, the two levers 15 of the first splicing block 6 and the second splicing block 9 can be moved simultaneously to overcome the pushing force of the spring 19, so that the two sliding rods 14 move closer to each other, thereby causing the locking rods 17 on both sides to disengage from the connecting groove 8 and retract into the movable groove 11, so that EVA board 1 can be removed from the splicing mechanism 5. Repeat the operation to completely remove it.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
