Abstract
Description
Technical Field
[0001] This utility model relates to the field of foamed shoe sole technology, and in particular to a high-performance foamed shoe sole that can achieve rapid degradation. Background Technology
[0002] Currently, EVA is a copolymer of ethylene and vinyl acetate, abbreviated as EVA. Compared with polyethylene, EVA has reduced crystallinity and improved flexibility, impact resistance, filler compatibility, and heat-sealing performance due to the introduction of vinyl acetate monomers into the molecular chain. EVA midsole refers to a shoe midsole formed in one step by injecting EVA into a mold and heating it at high temperature; it is also called a one-step foaming midsole.
[0003] For example, the authorized announcement number "CN211154050U" is named a biodegradable foamed shoe sole. The first and second fastening discs are distributed in the round openings on the left and right sides of the foamed shoe sole body. The internal threaded tube and threaded rod can increase the support strength of the foot and heel areas of the foamed shoe sole body. Moreover, the internal threaded tube and threaded rod can be removed when the shoes are discarded, thereby ensuring that the side wall of the foamed shoe sole body forms a cavity, increasing the contact area with air, soil and water, and accelerating the degradation of the foamed shoe sole body.
[0004] The above-mentioned and existing technologies have the following defects: long-term wear of the sole will cause impurities to enter the threaded rod and the inner threaded tube, resulting in adhesion and making it impossible to unscrew the threaded rod, thus affecting the degradation of the foamed sole. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-performance foamed shoe sole that can achieve rapid degradation.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a high-performance foamed shoe sole capable of rapid degradation, comprising a shoe sole body, the front surface of which has multiple first mounting grooves, the inner wall of which has a sleeve, one end of which has a fixing device, the front surface of which has a second mounting groove, the inner wall of which has a force-bearing rod, one end of which has an inclined surface, the front surface of which has a third mounting groove, a slider rotatably connected to one side of the inner wall of the third mounting groove, a reset driving device between the slider and the inner wall of the third mounting groove, an annular groove on the inner wall of the third mounting groove, an eccentric block on the side surface of the slider, the eccentric block being disposed inside the annular groove, an operating disc at the front end of the slider, an mounting cavity inside the sleeve, a reset spring on the upper surface of the mounting cavity, a base at the lower end of the reset spring, a first snap-fit post on the lower surface of the base, a snap-fit groove at the upper end of the annular groove, and the lower end of the first snap-fit post extending into the snap-fit groove.
[0008] Preferably, the front end of the third mounting slot is provided with a concealed slot, and the operation panel is disposed inside the concealed slot.
[0009] Preferably, the front surface of the control panel is provided with a handle.
[0010] Preferably, the reset drive device includes a fixing block and a torsion spring. The fixing block is disposed on one side surface of the slider, one end of the torsion spring is connected to the fixing block, and the other end of the torsion spring is connected to one side inner wall of the third mounting groove.
[0011] Preferably, the fixing device includes a fourth mounting groove, a protrusion, a through hole, a second snap-fit post, an end block, and a nut. The fourth mounting groove is disposed on the rear surface of the shoe sole body. The rear surface of the sleeve is provided with a protrusion. The rear end of the protrusion slides through the fourth mounting groove. The through hole is disposed on the surface of the protrusion. The second snap-fit post is disposed inside the through hole. The upper end of the second snap-fit post is provided with an end block. The lower end of the second snap-fit post is threadedly connected to a nut.
[0012] Preferably, two limiting posts are provided between the inner walls on both sides of the mounting cavity, and the base is slidably connected to the two limiting posts.
[0013] This invention proposes a high-performance foamed shoe sole that enables rapid degradation. The advantages are as follows: When discarding the shoes, rotating the control panel causes the eccentric block to push up the first locking post, disengaging it from the locking groove. Then, pulling the force-bearing rod disengages it from the second mounting groove. The fixing device, by unscrewing the nut and removing the second locking post, allows the protruding block to be pushed, disengaging the sleeve from the first mounting groove. This removes the sleeve and force-bearing rod, ensuring the formation of the first mounting groove inside the sole body. This increases the contact area with air, soil, and water, accelerating the degradation efficiency of the foamed shoe sole. Long-term wear of this foamed shoe sole eliminates concerns about impurities entering the sleeve, preventing adhesion between the sleeve and force-bearing rod, which could prevent removal and ensures complete degradation of the foamed shoe sole.
