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 sheets with splicing structure are composite materials with specific sizes or functions, which are spliced ​​together by multiple EVA sheets through hot pressing, ultrasonic welding or adhesive bonding processes. Its core feature is to break through the size limitations of a single EVA sheet and meet the needs of diverse scenarios through the combination of material properties. The splicing structure allows for the secondary processing of recycled EVA sheets, reducing the consumption of new materials. For example, EVA fragments from waste shoe midsoles can be cut and reassembled into floor mats, increasing the material recycling rate. Personalized customization trend: Consumers have increased demands for product appearance and function. The splicing structure can quickly respond to customized needs by flexibly combining EVA sheets of different colors and hardness.

[0003] Due to limitations in production equipment size and processes, traditional EVA sheets are difficult to directly produce large-size products. For example, in manufacturing large inflatable paddleboards or large-area industrial cushioning pads, a single EVA sheet cannot meet the size requirements, leading to high production difficulty and cost. Furthermore, the fixed performance of a single EVA sheet makes it difficult to simultaneously meet the diverse performance requirements of complex scenarios. In shoe sole applications, both good cushioning performance and high abrasion resistance are needed, which a single EVA sheet cannot achieve. Therefore, an EVA sheet with a splicing structure is proposed to solve these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an EVA sheet with a splicing structure, aiming to improve the problem that some splicing structures in the prior art are too cumbersome.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An EVA sheet with a splicing structure includes a fixing block, a screw is fixedly connected inside the fixing block, a wear-resistant layer is fixedly connected to the bottom of the fixing block, and the bottom of the screw is threadedly connected to the top of the wear-resistant layer. As a further description of the above technical solution: The fixed block is externally fixedly connected to a semi-circular hollow block, the bottom of which is fixedly connected to the top of the wear-resistant layer, and the inner side of which is fixedly connected to a semi-circular connecting buckle. As a further description of the above technical solution: The inner side of the semicircular connecting buckle is rotatably connected to a semicircular ring, and the bottom of the semicircular connecting buckle is fixedly connected to the top of the wear-resistant layer. As a further description of the above technical solution: The bottom of the semi-circular ring is rotatably connected to the top of the wear-resistant layer, and a fixing strip is fixedly connected to the outside of the semi-circular ring; As a further description of the above technical solution: The outer part of the fixing strip is rotatably connected to the inside of the semi-circular connecting buckle, and the outer part of the fixing strip is rotatably connected to the inside of the semi-circular hollow block; As a further description of the above technical solution: A shock-absorbing layer is fixedly connected to the bottom of the wear-resistant layer, and a moisture-proof layer is fixedly connected to the bottom of the shock-absorbing layer. An anti-slip strip is fixedly connected to the bottom of the moisture-proof layer. As a further description of the above technical solution: The wear-resistant layer is slidably connected to an L-shaped connecting strip on the outside. The inside of the L-shaped connecting strip is slidably connected to the outside of the moisture-proof layer. A fixing block b is rotatably connected to the inside of the L-shaped connecting strip. A screw two is threadedly connected to the inside of the fixing block b. The external thread of the screw two is threadedly connected to the inside of the L-shaped connecting strip.

[0006] This utility model has the following beneficial effects: 1. In this utility model, the fixed strip rotates to drive the semi-circular ring to work, and rotates the semi-circular ring 90 degrees so that each end of the semi-circular ring is left half, thereby achieving the fixing effect. When there are multiple boards that need to be spliced, they can be spliced ​​together using a splicer to increase the usable area of ​​the boards.

[0007] 2.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] Reference Figures 1 to 3 The present invention provides an embodiment of an EVA sheet with a splicing structure, comprising a fixing block 1, a screw 2 fixedly connected inside the fixing block 1, a wear-resistant layer 7 fixedly connected to the bottom of the fixing block 1, the bottom of the screw 2 fixedly connected to the top of the wear-resistant layer 7, a semi-circular hollow block 3 fixedly connected to the outside of the fixing block 1, the bottom of the semi-circular hollow block 3 fixedly connected to the top of the wear-resistant layer 7, a semi-circular connecting buckle 4 fixedly connected to the inside of the semi-circular connecting buckle 4, a semi-circular ring 5 rotatably connected to the inside of the semi-circular connecting buckle 4, the bottom of the semi-circular connecting buckle 4 fixedly connected to the top of the wear-resistant layer 7, the bottom of the semi-circular ring 5 rotatably connected to the top of the wear-resistant layer 7, a fixing strip 6 fixedly connected to the outside of the semi-circular ring 5, the outside of the fixing strip 6 rotatably connected to the inside of the semi-circular connecting buckle 4, and the outside of the fixing strip 6 rotatably connected to the inside of the semi-circular hollow block 3.

[0012] Reference Figures 2 to 4 The bottom of the fixing block 1 is fixedly connected to a wear-resistant layer 7, which can improve the surface coating hardness and resist daily scratches from keys, pen tips, etc. It can be used for a long time without producing obvious wear marks, thus extending the service life of the sheet. The bottom of the wear-resistant layer 7 is fixedly connected to a shock-absorbing layer 8. The shock-absorbing layer 8 with self-adhesive can be quickly pasted onto the surface of the equipment without professional tools, making it suitable for rapid assembly on the production line. The bottom of the shock-absorbing layer 8 is fixedly connected to a moisture-proof layer 9, which not only passively blocks moisture but also actively extends the life of the item and reduces environmental dependence costs. The bottom of the moisture-proof layer 9 is fixedly connected to an anti-slip strip 10, which can increase the static friction between the object and the ground and prevent the object from shifting during use. At the same time, when placing two identical sheets perpendicular to each other, they can be connected together with an L-shaped connecting strip 11, and the fixing block b12 can be pressed against the L-shaped connecting strip with the screw 13 to provide a fixing effect.

[0013] Working principle: The worker places the fixing block 1 at the position to be spliced ​​and fixes it to the top of the wear-resistant layer 7 with screw 1 2. At the same time, the semi-circular hollow block 3 and the semi-circular connecting buckle 4 to be fixed should be connected to the inside of the fixing block a1 to achieve the fixing effect. Then, another fixing block a1 is placed at the position to be fixed and fixed with screw 1 2. The two need to be aligned and fixed on the same horizontal plane. Otherwise, when the fixing strip 6 is rotated, the semi-circular ring 5 cannot be fixed. When the fixing is successful, the two spliced ​​semi-circular rings 5 ​​can achieve the fixing effect. At the same time, the two identical sheets are placed perpendicular to each other with L-shaped connecting strip 11 to connect them together. Then, screw 2 13 is turned to tightly connect the fixing block b12 and the L-shaped connecting strip 11 to achieve the fixing effect. This can realize the splicing of multi-layer sheets.

[0014] The wear-resistant layer 7, fixedly connected to the bottom of the fixed block 1, is a special board material with high hardness and wear resistance. It can not only effectively protect objects from wear, but also avoid the defects of simple hard and brittle materials that are prone to cracking. Furthermore, by extending the service life and reducing energy consumption and maintenance costs, it provides sustainable economic benefits for high-wear scenarios. The shock-absorbing layer 8, fixedly connected to the bottom of the wear-resistant layer 7, absorbs impact force and reduces vibration transmission through material deformation. Its lightweight, easy-to-install, and multi-functional integration characteristics reduce construction and maintenance costs, while meeting diverse needs such as environmental protection and safety. The moisture-proof layer 9, fixedly connected to the bottom of the shock-absorbing layer 8, is treated with a special process and has excellent moisture-proof and waterproof performance, which can effectively increase the service life. The anti-slip strip 10 fixed to the bottom of the moisture-proof layer 9 can increase the friction of the contact surface, extend the service life, and reduce maintenance costs. The L-shaped connecting strip can vertically splice two sheets together, and then use screw 13 to rotate to push the fixed block 12 closer to the L-shaped connecting strip 11 until it can no longer be pushed, which can realize multi-layer splicing of sheets and reduce the floor space.

[0015] 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.
