Description

Technical Field

[0001] The utility model relates to the technical field of EVA sheets, and specifically relates to an EVA sheet that can be quickly spliced and combined. Background Technique

[0002] The EVA sheet, whose full name is ethylene-vinyl acetate copolymer, is a general-purpose polymer. The EVA sheet has good chemical stability, aging resistance, ozone resistance, and is non-toxic, odorless, and transparent.

[0003] An EVA sheet with a splicing structure provided by the publication number "CN219133487U", through the settings of a rubber bottom pad, a first EVA sheet, side edge wrapping strips, and corner wrapping blocks, through the mutual connection and combination of different components, ensures the tight connection of the assembled EVA sheet. Using the rubber bottom pad as the bottom layer, a large rubber bottom pad has good anti-slip effect, which can prevent the overall slipping of the EVA sheet. Then, through the mutual cooperation of trapezoidal card slots, trapezoidal blocks, limiting slots, and limiting blocks, the first EVA sheet and the second EVA sheet, and the rubber bottom pad and the first EVA sheet are connected as a whole, ensuring that the EVA sheet will not simply split during use.

[0004] However, the above technical solution and the existing technologies have the following defects:

[0005] Although the EVA sheet has a splicing structure for splicing and combination, the connection stability of the mutually buckled trapezoidal blocks and trapezoidal card slots is not good during actual use, and when it is necessary to reinforce with side edge wrapping strips, the operation steps are also relatively cumbersome, which is not convenient for the user to quickly splice and combine the EVA sheet, and the practicability is poor. Content of the Utility Model

[0006] The purpose of the utility model is to provide an EVA sheet that can be quickly spliced and combined to solve the problems raised in the above background technique.

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

[0008] An EVA sheet that can be quickly spliced and combined, including an EVA sheet body and a splicing frame. The EVA sheet body is embedded in the upper end surface of the splicing frame. Splicing components are arranged on the side of the splicing frame, and the splicing components are used for quickly splicing and combining the splicing frame. A shielding component is arranged on the upper end surface of the splicing frame, and the shielding component is used for shielding the opening at the upper end surface of the splicing components.

[0009] Preferably, the splicing component includes a plug connector, a socket, a positioning groove, a positioning insert, a return spring, a support shaft, a pressing seat, a driving rack, a driven rack, and a transmission gear. The plug connectors are arranged on the left end face and the rear end face of the splicing frame. The positioning groove is formed on the upper end face of the plug connector.

The pressing seats are installed on the right side and the front side inside the splicing frame. The driving rack is arranged on the inner wall of the pressing seat. The transmission gear meshes with the driving rack and the driven rack. The support shaft is installed inside the transmission gear.

[0010] Preferably, the shielding component includes a shielding sheet, a storage groove, and a dial. The storage grooves are formed on the right side and the front side inside the splicing frame. The shielding sheet is inserted into the storage groove. The dial is arranged on the upper end face of the shielding sheet.

[0011] Preferably, a magnetic rubber sheet is arranged on the left end face of the shielding sheet. The adsorption magnet sheet is attached to the left end face of the magnetic rubber sheet. The storage groove matches the shielding sheet.

[0012] Preferably, a fixing screw is installed inside the pressing seat. The turning cap is arranged on the upper end of the fixing screw.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. By inserting the plug connector into the corresponding socket groove, multiple EVA sheet bodies can be quickly spliced and combined with the help of the splicing frame. During this process, the limit guide head will also be inserted into the corresponding limit guide groove to prevent the splicing frame from being misaligned during the splicing and combination process. After the plug connector is inserted into the socket groove, the extrusion force of the return spring will cause the positioning insert piece to be clamped in the corresponding positioning groove, preventing the plug connector inserted into the socket groove from loosening and slipping easily during use. In the later stage, the user only needs to press down the pressing seat, and the downward-moving pressing seat will drive the active rack to move downward together. The downward-moving active rack will drive the positioning insert piece to move upward through the transmission gear and the driven rack to release the locking of the plug connector, so that the user can disassemble the spliced and combined splicing frame;

[0017] 2. By sliding and closing the shielding piece, the shielding piece can shield the lower pressing seat, preventing multiple pressing seats from being accidentally touched or adhering to dust during use. At the same time, the adsorption magnet piece can adsorb the magnetic rubber piece that fits together, preventing the shielding piece that is closed in place from sliding open easily.

The EVA sheet body 1 is fixedly embedded in the splicing frame 2 by an adhesive method. A splicing component 3 is arranged on the side of the splicing frame 2, and the splicing component 3 is used for quickly splicing and combining the splicing frame 2. A shielding component 4 is arranged on the upper end face of the splicing frame 2, and the shielding component 4 is used for shielding the opening on the upper end face of the splicing component 3 to prevent the splicing component 3 from being accidentally touched or adhered with dust during use.

[0029] The splicing component 3 includes a plug connector 31, a plug socket 34, a positioning groove 35, a positioning insert 36, a return spring 37, a support shaft 38, a pressing seat 311, a driving rack 312, a driven rack 313 and a transmission gear 314. Plug connectors 31 are arranged on the left end face and the rear end face of the splicing frame 2. The plug connectors 31 are integrally formed with the splicing frame 2. Plug sockets 34 are provided on the front end face and the right end face of the splicing frame 2. The plug connectors 31 are matched with the plug sockets 34. The matched plug connectors 31 and plug sockets 34 facilitate the user to quickly splice and combine multiple splicing frames 2. The upper end face of the plug connector 31 is inclined. The plug connector 31 with an inclined upper end face can apply an upward extrusion force to the positioning insert 36 during the process of inserting into the plug socket 34, so that the plug connector 31 can be smoothly inserted into the plug socket 34. A positioning groove 35 is provided on the upper end face of the plug connector 31, and the positioning groove 35 is matched with the positioning insert 36. The positioning insert 36 is installed on the upper side inside the plug socket 34. The matched positioning insert 36 and positioning groove 35 can position the plug connector 31 inserted into the plug socket 34 to prevent the multiple splicing frames 2 after splicing and combination from easily loosening and separating.

[0030] A reset spring 37 is installed on the upper end surface of the positioning insert piece 36. The reset spring 37 can apply a downward extrusion force to the positioning insert piece 36. A driven rack 313 is arranged on the inner wall of the positioning insert piece 36. The driven rack 313 and the positioning insert piece 36 are of an integral structure. The driven rack 313 can drive the positioning insert piece 36 to move up and down. Pressing seats 311 are installed on the right side and the front side inside the splicing frame 2.

A driving rack 312 is arranged on the inner wall of the pressing seat 311. A transmission gear 314 is meshed between the driving rack 312 and the driven rack 313. When the driving rack 312 moves up and down, it can drive the transmission gear 314 to rotate, so that the transmission gear 314 drives the driven rack 313 to move up and down. A support shaft 38 is installed inside the transmission gear 314. Both ends of the support shaft 38 are inside the splicing frame 2. The support shaft 38 and the transmission gear 314 are of an integral structure. The support shaft 38 enables the transmission gear 314 to have the ability to rotate.

[0031] A fixing screw 315 is installed inside the pressing seat 311. An internal thread hole 318 is opened directly below the fixing screw 315. The fixing screw 315 and the internal thread through hole can fix the pressing seat 311 that has moved down in place. A turning cap 316 is arranged at the upper end of the fixing screw 315.

Limit guiding heads 32 are arranged on the left end face and the rear end face of the splicing frame 2, and the end face of the limit guiding head 32 is semi-circular. The limit guiding heads 32 and the splicing frame 2 are of an integral structure. Limit guiding grooves 33 are opened on the front end face and the right end face of the splicing frame 2, and the limit guiding grooves 33 match the limit guiding heads 32. The matching limit guiding grooves 33 and the limit guiding heads 32 prevent misalignment during the splicing and combination of multiple splicing frames 2, thereby ensuring the splicing and combination stability of the splicing frame 2.

[0032] Embodiment 2:

[0033] On the basis of Embodiment 1, in this embodiment, by sliding and closing the shielding piece 41, the shielding piece 41 can shield the lower pressing seat 311, avoiding accidental contact or dust adhesion to multiple pressing seats 311 during use. At the same time, the adsorption magnet sheet 45 can adsorb the magnetic rubber sheet 44 that fits, preventing the shielding piece 41 that is closed in place from easily sliding open.

[0034] The shielding component 4 includes a shielding sheet 41, a storage groove 42, and a dial 43. Storage grooves 42 are provided on the right side and the front side inside the splicing frame 2. The storage grooves 42 match the shielding sheet 41, and the storage grooves 42 facilitate the movement of the shielding sheet 41 inside the splicing frame 2. The shielding sheet 41 is inserted into the storage groove 42. The shielding sheet 41 can shield the lower pressing seat 311 to prevent the lower pressing seat 311 from being accidentally touched or adhered with dust during use. A dial 43 is provided on the upper end surface of the shielding sheet 41. The dial 43 and the shielding sheet 41 are of an integral structure. The dial 43 facilitates the user to manually move and open the shielding sheet 41. A magnetic rubber sheet 44 is provided on the left end surface of the shielding sheet 41. The magnetic rubber sheet 44 is fixed to the left end surface of the shielding sheet 41 by an adhesive method. An adsorption magnet sheet 45 is attached to the left end surface of the magnetic rubber sheet 44. The adsorption magnet sheet 45 is fixed inside the splicing frame 2 by an adhesive method. The adsorption magnet sheet 45 can adsorb the adhered magnetic rubber sheet 44 to prevent the shielding sheet 41 in the closed position from sliding open easily.

[0035] Working principle: when it is necessary to splice and assemble the EVA sheet body 1, the user first assembles and splices the multiple splicing frames 2 horizontally. During this process, the plug connector 31 needs to be inserted into the corresponding plug slot 34, and the limiting guide head 32 will also be inserted into the corresponding limiting guide slot 33 to prevent the splicing frame 2 from being misaligned during the splicing and assembling process. The plug connector 31 inserted into the plug slot 34 will be locked by the positioning plug 36 through the positioning slot 35, and the return spring 37 will also apply a downward extrusion force to the positioning plug 36, thereby preventing the plug connector 31 inserted into the plug slot 34 from loosening and slipping during use. After the multiple splicing frames 2 are assembled and spliced ​​horizontally, the multiple splicing frames 2 can be assembled and spliced ​​vertically respectively, so as to quickly splice and assemble the multiple EVA sheet bodies 1; during the use of the splicing frames 2 after the multiple splicing and assembling, the closed shielding sheet 41 will shield the multiple lower pressure seats 311 to prevent the multiple lower pressure seats 311 from being accidentally touched during use. The magnetic sheet 45 can absorb the corresponding magnetic rubber sheet 44 to prevent the shielding sheet 41 from sliding open easily when the multiple splicing frames 2 are used separately. In the later use process, when it is necessary to disassemble multiple splicing frames 2 separately, the user first slides the multiple shielding sheets 41 open respectively through the pry pieces 43, and then presses the multiple pressing seats 311 into place respectively. In this process, when one hand presses the pressing seat 311 downward into place, the other hand presses the rotating cap 311 into place. 6. The fixing screw 315 is rotated forward to engage and fix it in the internal threaded hole 318, so that the fixing screw 315 fixes the lower pressure seat 311. At the same time, the lower pressure seat 311 that moves downward will drive the active rack 312 to move downward together, so that the moving active rack 312 drives the driven rack 313 to move upward through the transmission gear 314, and then the driven rack 313 drives the positioning plug 36 to move upward together to release the lock of the plug connector 31, so that the user can separate and disassemble multiple splicing frames 2.
