Description

Technical Field

[0001] This utility model relates to the field of EVA sheet technology, specifically 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, heat insulation, moisture resistance, and chemical corrosion resistance. It is also non-toxic and non-absorbent. EVA rubber and plastic products can be designed and processed into various shapes. Its shock resistance is better than that of traditional foam materials such as polystyrene (foam) and meets environmental protection requirements.

[0003] According to the search, CN219133487U discloses an EVA sheet with a splicing structure, which relates to the field of EVA sheets. It includes a rubber base, on which a first EVA sheet and a second EVA sheet are movably mounted. The first EVA sheet is in contact with the second EVA sheet, and side edging strips are movably mounted on the sides of both the rubber base and the first EVA sheet.

[0004] The aforementioned utility model, through the arrangement of a rubber base pad, a first EVA sheet, side edging strips, and corner edging blocks, ensures a tight connection of the assembled EVA sheets through the interconnection and combination of different components. Utilizing the rubber base pad as the bottom layer, a large rubber base pad provides excellent anti-slip properties, preventing the EVA sheet from slipping. However, in actual use, the rubber base pad has excellent waterproof properties, meaning that water, whether on the surface or seeping into the gaps, cannot be drained after the EVA sheets are spliced. This not only keeps the entire assembly constantly damp but also reduces its service life.

[0005] Therefore, it is particularly important to design an EVA sheet with a splicing structure to solve the above-mentioned defects. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention designs an EVA sheet with a splicing structure. This EVA sheet aims to solve the technical problems of poor waterproofing and reduced service life of existing EVA sheets.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An EVA sheet with a splicing structure includes multiple sets of EVA sheet bodies spliced ​​together. Multiple sets of splicing blocks are fixedly connected to the outer side of the multiple sets of EVA sheet bodies. Multiple sets of splicing grooves adapted to the splicing blocks are opened on the outer side of the multiple sets of EVA sheet bodies. A drainage mechanism is provided on the top of each set of EVA sheet bodies. A corner frame is covered on the outer side of the multiple sets of EVA sheet bodies. Multiple sets of positioning mechanisms are installed inside the corner frame.

[0009] The drainage mechanism includes multiple sets of anti-slip protrusions fixedly connected to the top of the EVA sheet body. Water inlet channels are provided at both the left and right ends of the top of the EVA sheet body. Multiple sets of connecting channels are provided between the two sets of water inlet channels and at the intervals of the multiple sets of anti-slip protrusions. Water guide channels are provided at the connection between the outer side of the EVA sheet body and the water inlet channels. Water flow channels are provided at the bottom of the EVA sheet body at the position corresponding to the water guide channels.

[0010] As a preferred embodiment of this utility model, multiple sets of the connecting grooves are distributed at equal intervals on the top of the EVA sheet body, and a filter screen is installed at the bottom of the water guiding groove.

[0011] As a preferred embodiment of this utility model, positioning heads are inserted into the connection points of the multiple sets of EVA sheet bodies, and slots adapted to the positioning heads are opened at the four corners of the multiple sets of EVA sheet bodies.

[0012] As a preferred embodiment of this utility model, the bottom of the positioning head is fixedly connected to multiple sets of positioning posts, and positioning holes are opened at the positions corresponding to the multiple sets of positioning posts inside the multiple sets of slots.

[0013] As a preferred embodiment of this utility model, multiple sets of moisture-absorbing cavities are provided inside the multiple sets of EVA sheet bodies, and drainage grooves are provided at the bottom of the multiple sets of EVA sheet bodies at positions corresponding to the moisture-absorbing cavities. Multiple sets of connecting holes are provided between the multiple sets of drainage grooves and the moisture-absorbing cavities.

[0014] As a preferred embodiment of this utility model, the moisture-absorbing cavity is designed in a trapezoidal shape, and the interior of the moisture-absorbing cavity is filled with silica gel particle desiccant.

[0015] As a preferred embodiment of this utility model, an accommodating cavity is formed between the inner side of the corner frame and the EVA sheet body, which is adapted to the splicing block. An operating groove is provided inside the corner frame at a position corresponding to the positioning mechanism.

[0016] As a preferred embodiment of this utility model, the positioning mechanism includes a connecting frame fixedly connected inside the operating slot, an adsorption cover fixedly connected to the bottom of the connecting frame, a rotating stud threaded inside the connecting frame, a rubber adsorption pad rotatably connected to the bottom end of the rotating stud, and an adsorption cavity formed between the rubber adsorption pad and the adsorption cover.

[0017] As a preferred embodiment of this utility model, an operating handle is sleeved on the top of the rotating stud, and a fixing nut is threadedly connected to the outside of the rotating stud and inside the operating handle.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. In this utility model, through the coordinated design of the EVA sheet body and the drainage mechanism, when water droplets fall on the surface of the EVA sheet, the anti-slip protrusions not only improve the anti-slip effect of the top of the EVA sheet body, but also allow the water to flow into the water inlet channel along the connecting grooves between the anti-slip protrusions, then out through the water guide channel, and finally out through the water discharge channel. This gives the EVA sheet body good drainage performance, preventing the whole body from being constantly damp. The filter screen inside the water guide channel can effectively filter impurities and prevent clogging that affects the drainage effect. The silica gel particles absorb the moisture inside the sheet, and the moisture enters the drainage channel through the connecting holes and is finally discharged, effectively reducing the humidity inside the EVA sheet body. Moreover, when the EVA sheet body is under pressure, the trapezoidal moisture-absorbing cavity is under pressure, which can accelerate the expulsion of moisture, thereby preventing problems such as mold and deterioration caused by moisture, further improving the waterproof effect of the EVA sheet body, and extending its service life.

[0020] 2. In this utility model, through the cooperative design of the corner frame and the positioning mechanism, and through the mutual cooperation of the splicing block and the splicing groove, multiple sets of EVA sheet bodies are tightly spliced. Then, the corner frame is wrapped around the outside of the EVA sheet body, and the splicing block is located inside the receiving cavity, thus achieving external protection. The positioning mechanism is then used to position and fix the corner frame, which not only improves the ease of installation of the corner frame, but also improves the overall stability after installation.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] Example: Please refer to Figures 1-8 This utility model provides a technical solution:

[0032] An EVA sheet with a splicing structure includes multiple sets of EVA sheet bodies 1 spliced ​​together. Multiple sets of splicing blocks 2 are fixedly connected to the outer side of the multiple sets of EVA sheet bodies 1. Multiple sets of splicing grooves 3 adapted to the splicing blocks 2 are opened on the outer side of the multiple sets of EVA sheet bodies 1. A drainage mechanism 4 is provided on the top of each set of EVA sheet bodies 1. The outer side of the multiple sets of EVA sheet bodies 1 is covered with a corner frame 5. Multiple sets of positioning mechanisms 6 are installed inside the corner frame 5.

[0033] First, in this embodiment, the specific structure of the drainage mechanism 4 is as follows:

[0034] The drainage mechanism 4 includes multiple sets of anti-slip protrusions 401 fixedly connected to the top of the EVA sheet body 1. Water inlet channels 402 are provided at both ends of the top of the EVA sheet body 1. Multiple connecting channels 403 are provided between the two sets of water inlet channels 402 and at the intervals between the multiple sets of anti-slip protrusions 401. A water guide channel 404 is provided at the connection between the outer side of the EVA sheet body 1 and the water inlet channel 402. A water flow channel 405 is provided at the bottom of the EVA sheet body 1 at a position corresponding to the water guide channel 404. The drainage mechanism 4 connects to the splicing block 2. The interlocking of the grooves 3 enables the tight splicing of multiple EVA sheet bodies 1. When water droplets fall on the surface of the EVA sheet, the anti-slip protrusions 401 not only improve the anti-slip effect on the top of the EVA sheet body 1, but also allow the water to flow into the water inlet groove 402 along the connecting grooves 403 between the anti-slip protrusions 401, then be discharged through the water guide groove 404 and finally discharged through the water outlet groove 405. This gives the EVA sheet body 1 good drainage performance, preventing the whole from being constantly damp, thereby improving the waterproof and anti-slip effects.

[0035] Furthermore, multiple sets of connecting channels 403 are evenly distributed on the top of the EVA sheet body 1, and a filter screen 406 is installed at the bottom inside the water guide channel 404. The filter screen 406 inside the water guide channel 404 can effectively filter impurities and prevent clogging from affecting the drainage effect.

[0036] Then, positioning heads 101 are inserted into the connection points of multiple EVA sheet bodies 1. Slots 102 adapted to the positioning heads 101 are opened at the four corners of the multiple EVA sheet bodies 1. Multiple positioning posts 103 are fixedly connected to the bottom of the positioning heads 101. Positioning holes 104 are opened at the positions corresponding to the multiple positioning posts 103 inside the multiple slots 102. When the positioning head 101 is inserted into the slot 102, the positioning posts 103 cooperate with the positioning holes 104 to achieve precise positioning. This not only enhances the connection strength between the EVA sheet bodies 1, but also facilitates disassembly and reinstallation, improving the flexibility and durability of the overall structure.

[0037] The multiple sets of EVA sheet bodies 1 each have multiple moisture-absorbing cavities 105 inside. Drainage grooves 106 are provided at the bottom of each set of EVA sheet bodies 1 corresponding to the moisture-absorbing cavities 105. Multiple connecting holes 107 are provided between the drainage grooves 106 and the moisture-absorbing cavities 105. The moisture-absorbing cavities 105 are trapezoidal in shape and filled with silica gel granules desiccant 108. The silica gel granules desiccant 108 absorb moisture inside the sheet, and the moisture is discharged through the connecting holes 107 into the drainage grooves 106. This effectively reduces the humidity inside the EVA sheet body 1. Furthermore, when the EVA sheet body 1 is subjected to pressure, the trapezoidal moisture-absorbing cavities 105 are compressed, accelerating the expulsion of moisture. This prevents mold and deterioration caused by dampness, further improving the waterproof effect of the EVA sheet body 1 and extending its service life.

[0038] Secondly, a receiving cavity 501 is formed between the inner side of the corner frame 5 and the EVA sheet body 1, which is adapted to the splicing block 2. An operating groove 502 is provided inside the corner frame 5 at the position corresponding to the positioning mechanism 6. When the corner frame 5 is wrapped around the outside of the EVA sheet body 1, the splicing block 2 is located inside the receiving cavity 501. This not only achieves external protection, but also effectively avoids overall displacement after the positioning mechanism 6 is positioned and fixed by the operating groove 502, which further improves the overall stability after installation.

[0039] Finally, the positioning mechanism 6 includes a connecting frame 601 fixedly connected inside the operating slot 502. An adsorption cover 602 is fixedly connected to the bottom of the connecting frame 601. A rotating stud 603 is threadedly connected inside the connecting frame 601. A rubber adsorption pad 604 is rotatably connected to the bottom end of the rotating stud 603. An adsorption cavity 605 is formed between the rubber adsorption pad 604 and the adsorption cover 602. An operating handle 606 is sleeved on the top end of the rotating stud 603. A fixing screw is threadedly connected to the outside of the rotating stud 603 and inside the operating handle 606. After the operating handle 606 is placed on the outside of the rotating stud 603, the fixing nut 607 is tightened to secure it. Then, the operating handle 606 can rotate at the top of the operating groove 502. By turning the operating handle 606, the rotating stud 603 is rotated, which causes the rubber adsorption pad 604 to move upward and compress the adsorption cavity 605. The rubber adsorption pad 604 is used to adsorb the ground, thereby positioning and fixing the corner frame 5. This not only improves the ease of installation of the corner frame 5, but also improves the overall stability after installation.

[0040] In this embodiment, the specific implementation scenario is as follows: Multiple EVA sheet bodies 1 are tightly spliced ​​together through the cooperation of splicing block 2 and splicing groove 3. Then, corner frame 5 is wrapped around the outside of the EVA sheet body 1. Splicing block 2 is located inside the receiving cavity 501, achieving external protection. The corner frame 5 is then positioned and fixed using positioning mechanism 6. When water droplets fall on the surface of the EVA sheet, the anti-slip protrusions 401 not only improve the anti-slip effect on the top of the EVA sheet body 1, but the water also flows along the connecting groove 403 between the anti-slip protrusions 401 into the water inlet trough 402, then is discharged through the water guide trough 404 and finally drained through the water discharge trough 405, giving the EVA sheet body 1 good drainage performance and preventing overall water loss. When in a humid state, the filter screen 406 inside the water guide channel 404 can effectively filter impurities and prevent clogging that could affect drainage. The silica gel desiccant 108 absorbs moisture inside the sheet, and the moisture enters the drainage channel 106 through the connecting hole 107 and is eventually discharged, effectively reducing the humidity inside the EVA sheet body 1. Moreover, when the EVA sheet body 1 is subjected to pressure, the trapezoidal moisture-absorbing cavity 105 is subjected to pressure, which can accelerate the expulsion of moisture, thereby preventing problems such as mold and deterioration caused by moisture. The entire operation process is simple and convenient. This utility model, through its design, can prevent problems such as mold and deterioration caused by moisture, improve the waterproof effect of the EVA sheet body 1, extend its service life, and improve the overall stability after installation.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
