Description

Technical Field

[0001] This utility model relates to the field of glue-free shoe technology, and in particular to a glue-free shoe model based on modular design. Background Technology

[0002] Traditional shoemaking processes typically rely on glue to fix the upper and sole of the shoe. This process poses environmental pollution problems, as the chemicals in the glue may harm human health and the ecological environment. With the increasing global awareness of environmental protection, the footwear industry is accelerating its development towards low-carbon and environmentally friendly directions. For example, using biodegradable materials, reducing the use of glue, and developing glue-free bonding technologies have become industry consensus.

[0003] In existing technologies, glue is usually used to fix the upper and sole of the shoe. This process has environmental pollution problems. The chemicals in the glue can harm human health and the ecological environment. Moreover, the connection between the sole and the upper is a key part of the shoe's waterproofing. Moisture or rainwater can easily seep into the shoe through the gaps at the connection, thus affecting the shoe's waterproof performance. Therefore, a glue-free shoe model based on modular design is proposed to solve the above-mentioned problems. Utility Model Content

[0004] To address the technical problems in existing technologies that typically rely on glue to fix the upper and sole, where the chemicals in the glue can harm human health and the environment, and where the connection between the sole and upper is a critical part of waterproofing, allowing moisture or rainwater to easily penetrate into the shoe through the gaps at the connection, this application provides a glue-free shoe model based on a modular design.

[0005] This utility model proposes a glue-free shoe model based on modular design, including an upper and a sole. The lower surface of the upper is provided with a connecting mechanism, which includes a limiting groove and a club. The club is limited and constrained by the wedge-shaped locking surface of the limiting groove.

[0006] The lower surface of the shoe upper is provided with a sealing mechanism, which includes a sealing ring. The sealing ring seals the connection between the shoe upper and the sole through its elastic deformation.

[0007] Preferably, the connecting mechanism further includes a connecting strip, which is fixed to the lower surface of the shoe upper by stitching.

[0008] Through the above technical solution, the connecting strip is fixed to the shoe upper by the stitching thread. The stitching thread is made of high-strength polyester sewing thread, which has high strength and abrasion resistance, is suitable for withstanding repeated wear and bending, and has good resistance to ultraviolet rays, sweat and common cleaning agents.

[0009] Preferably, a round rod is fixedly installed on the lower surface of the connecting strip, and a groove is formed on the lower end surface of the round rod.

[0010] The above technical solution involves fixing the connecting strip to the round rod, and providing a groove on the lower surface of the round rod to facilitate the sliding of the ball rod that is slidably inserted into it, so that the ball rod retracts back into the groove when it is squeezed.

[0011] Preferably, the two cues are slidably inserted into the inner wall of the groove, and a spring is fixedly installed on one end of one cue, and the spring is fixedly installed on one end of the other cue. The spring is made of stainless steel.

[0012] The above technical solution uses a cue stick that slides into a groove, fixing it without affecting its movement. Springs are used to fix the two cue sticks respectively. After the two cue sticks are compressed under force, the springs can reset them. The springs are made of stainless steel, which has good elasticity, fatigue strength and excellent corrosion resistance.

[0013] Preferably, the limiting groove is formed on the upper surface of the sole, and the connecting strip, the round rod, the cue stick, and the sole are all made of TPU.

[0014] The above technical solution involves a limiting groove on the sole of the shoe. This groove is a circular recess of the same size as the rod. At the lower end of this circular recess, corresponding to the position of the cue stick on the rod, are two wedge-shaped recesses. The circular recess provides the rod with a precise installation position and sliding space, ensuring the rod can smoothly enter and be positioned on the sole. When the rod, along with the cue stick attached to it, is pushed into the circular recess, the cue stick will contact the entrance of the wedge-shaped recess. Due to the spring force, the cue stick will attempt to move deeper into the wedge-shaped recess. The geometry of the wedge-shaped surface determines the direction of movement when the cue stick moves outward under the spring force. It will get stuck at the narrower end of the wedge. At this point, to remove the cue stick, an external force is needed to overcome the spring force and in the opposite direction overcome the huge locking force generated by the wedge. This is usually much greater than the pushing force during installation. Therefore, it can withstand various dynamic loads during wear, such as the impact and shear force during walking, running and jumping, ensuring that the upper and sole will not separate accidentally. The materials of the connecting strip, round rod, cue stick and sole are all made of TPU, which has excellent tensile strength, tear strength and abrasion resistance. It can withstand the stress in daily wear, and its flexibility allows the connecting strip to adapt to the bending deformation of the upper and sole, and it is not easy to break.

[0015] Preferably, the sealing mechanism further includes a cord hole formed on the upper surface of the shoe upper.

[0016] The above technical solution uses holes on the shoe upper to allow users to thread shoelaces or ropes through these holes and tie or knot them around the holes, thereby tightening and securing the shoe upper to the foot.

[0017] Preferably, the sealing ring is fixed to the lower surface of the connecting strip by a stitch, the inner wall of the circular hole of the sealing ring is slidably connected to the outer surface of the circular rod, and the sealing ring is made of silicone.

[0018] Through the above technical solution, the sealing ring is fixed to the connecting strip by the stitching line. The stitching line is also made of nylon. The sealing ring is slidably connected to the round rod, sealing it without affecting its movement. The sealing element is made of silicone, which has excellent elasticity and resilience, and can closely fit the surface of the round rod and seal the contact area between the connecting strip and the sole, thereby forming an effective sealing barrier.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By setting a connecting mechanism, the cue stick is constrained and limited. The connecting strip is fixed to the upper through stitching and is also fixedly installed with the round rod. When the round rod, along with the cue stick on it, is pushed into the circular groove of the limiting slot, the cue stick will contact the entrance of the wedge-shaped groove. Due to the push force from the spring, the cue stick will try to move deeper into the wedge-shaped groove. The geometry of the wedge surface determines that when the cue stick moves outward under the action of the spring force, it will be stuck at the narrower end of the wedge surface. At this time, to make the cue stick come out, an external force that overcomes the spring force and the huge locking force generated by the wedge surface needs to be applied. This is usually much larger than the pushing force during installation. Therefore, it can withstand various dynamic loads during wear, such as the impact and shear force during walking, running and jumping, ensuring that the upper and sole will not separate accidentally. This solves the technical problem that the existing technology usually relies on glue to fix the upper and sole. This process has environmental pollution problems, and the chemicals in the glue can cause harm to human health and the ecological environment.

[0021] 2. By setting up a sealing mechanism, the connection between the upper and the sole is sealed. Drawstring holes are located on the upper, allowing users to thread shoelaces or ropes through these holes and tie or knot them around the holes, thus tightening and securing the upper to the foot. The sealing ring is fixed to the connecting strip by stitching, which is also made of nylon. The sealing element is made of silicone, which has excellent elasticity and resilience, allowing it to closely conform to the surface of the round rod and seal the contact area between the connecting strip and the sole, forming an effective sealing barrier. This solves the technical problem in existing technologies where the connection between the sole and the upper is a critical area for waterproofing, and moisture or rainwater can easily penetrate into the shoe through gaps at the connection, thus affecting the shoe's waterproof performance.

[0030] 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.

[0031] Reference Figures 1-7 A modular design-based glue-free shoe includes an upper 1 and a sole 11. The lower surface of the upper 1 is provided with a connecting mechanism, which includes a limiting groove 5 and a cue stick 4. The cue stick 4 is limited and constrained by the wedge-shaped locking surface of the limiting groove 5.

[0032] To ensure the stitching has high strength and abrasion resistance, the connecting mechanism also includes a connecting strip 2. The connecting strip 2 is fixed to the lower surface of the upper 1 by the stitching. The connecting strip 2 is fixed to the upper 1 by the stitching. The stitching is made of high-strength polyester sewing thread, which has high strength and abrasion resistance, is suitable for withstanding repeated wear and bending, and has good resistance to ultraviolet rays, sweat and common cleaning agents.

[0033] To allow the cue stick 4 to retract into the groove 31 when compressed, a round rod 3 is fixedly installed on the lower surface of the connecting strip 2. The lower end surface of the round rod 3 has a groove 31. The round rod 3 is fixedly installed and fixed by the connecting strip 2. The groove 31 on the lower end surface of the round rod 3 facilitates the sliding of the cue stick 4, which is slidably inserted with it, so that the cue stick 4 retracts into the groove 31 when compressed.

[0034] To ensure the spring 41 has good elasticity, two cue sticks 4 are slidably inserted into the inner wall of the groove 31. A spring 41 is fixedly installed on one end of one cue stick 4, and the spring 41 is fixedly installed on one end of the other cue stick 4. The spring 41 is made of stainless steel. By sliding the cue sticks 4 into the groove 31, it is fixed without affecting their movement. The spring 41 is fixedly installed on both cue sticks 4. After the two cue sticks 4 are compressed under force, the spring 41 can reset them. The spring 41 is made of stainless steel, which has good elasticity, fatigue strength, and excellent corrosion resistance.

[0035] To ensure that the upper 1 and sole 11 do not accidentally separate, a limiting groove 5 is formed on the upper surface of the sole 11. The connecting strip 2, round rod 3, cue 4, and sole 11 are all made of TPU and are connected to the sole 11 through the limiting groove 5. The limiting groove 5 is a circular groove of the same size as the round rod 3. At the lower end of the circular groove, corresponding to the position of the cue 4 on the round rod 3, there are two wedge-shaped grooves. The circular groove provides the round rod 3 with a precise installation position and sliding space, ensuring that the round rod 3 can smoothly enter and be positioned on the sole 11. When the round rod 3, together with the cue 4 on it, is pushed into the circular groove, the cue 4 will contact the entrance of the wedge-shaped groove. Due to the pushing force from the spring 41, the cue 4 will attempt to move deeper into the wedge-shaped groove. The geometry of the wedge surface determines that when the cue stick 4 moves outward under the force of the spring 41, it will be stuck at the narrower end of the wedge surface. At this time, to remove the cue stick 4, an external force is required to overcome the force of the spring 41 and in the opposite direction overcome the huge locking force generated by the wedge surface. This is usually much larger than the pushing force during installation. Therefore, it can withstand various dynamic loads during the wearing process, such as the impact and shear force during walking, running and jumping, ensuring that the upper 1 and the sole 11 will not separate accidentally. The materials of the connecting strip 2, the round rod 3, the cue stick 4 and the sole 11 are all made of TPU, which has excellent tensile strength, tear strength and abrasion resistance, and can withstand the stress in daily wear. Moreover, its flexibility allows the connecting strip 2 to adapt to the bending deformation of the upper 1 and the sole 11 and is not easy to break.

[0036] By setting a connecting mechanism, the cue stick 4 is constrained and limited. The connecting strip 2 is fixed to the upper 1 by the stitching and is also fixedly installed to the round rod 3. When the round rod 3, together with the cue stick 4 on it, is pushed into the circular groove of the limiting groove 5, the cue stick 4 will contact the entrance of the wedge-shaped groove. Due to the pushing force from the spring 41, the cue stick 4 will attempt to move deeper into the wedge-shaped groove. The geometry of the wedge-shaped surface determines that when the cue stick 4 moves outward under the force of the spring 41, it will be stuck at the narrower end of the wedge-shaped surface. At this time, it is necessary to... To retract the cue stick 4, an external force is required that overcomes the force of the spring 41 and in turn overcomes the enormous locking force generated by the wedge surface. This force is usually much greater than the pushing force during installation, thus enabling it to withstand various dynamic loads during wear, such as the impact and shear force during walking, running, and jumping. This ensures that the upper 1 and the sole 11 will not separate accidentally, solving the problem in the prior art where glue is usually used to fix the upper 1 and the sole 11. This process has environmental pollution problems, and the chemicals in the glue can harm human health and the ecological environment.

[0037] To seal the connection between the upper 1 and the sole 11, a sealing mechanism is provided on the lower surface of the upper 1. The sealing mechanism includes a sealing ring 7, which seals the connection between the upper 1 and the sole 11 through its elastic deformation.

[0038] In order to tighten and secure the upper 1 to the foot, the sealing mechanism also includes a cord hole 6, which is formed on the upper surface of the upper 1. The cord hole 6 is formed on the upper 1 so that the user can pass the shoelaces or ropes through these cord holes 6 and tie or knot them around the cord holes 6, thereby tightening and securing the upper 1 to the foot.

[0039] To seal the contact area between the connecting strip 2 and the sole 11, a sealing ring 7 is fixed to the lower surface of the connecting strip 2 by a stitch. The inner wall of the circular hole of the sealing ring 7 is slidably connected to the outer surface of the round rod 3. The sealing ring 7 is made of silicone. The sealing ring 7 is fixed to the connecting strip 2 by a stitch, which is also made of nylon. The sealing ring 7 is slidably connected to the round rod 3, sealing it without affecting its movement. The sealing material is silicone, which has excellent elasticity and resilience, and can closely fit the surface of the round rod 3 and seal the contact area between the connecting strip 2 and the sole 11, thereby forming an effective sealing barrier.

[0040] By setting a sealing mechanism, the connection between the upper 1 and the sole 11 is sealed. The rope holes 6 are opened on the upper 1, making it easy for users to pass shoelaces or ropes through these rope holes 6 and tie or knot them around the rope holes 6, thereby tightening and fixing the upper 1 to the foot. The sealing ring 7 is fixed to the connecting strip 2 by the stitching thread, which is also made of nylon. The sealing material is silicone, which has excellent elasticity and resilience, can closely fit the surface of the round rod 3, and seal the contact area between the connecting strip 2 and the sole 11, thereby forming an effective sealing barrier. This solves the technical problem in the prior art that the connection between the sole 11 and the upper 1 is a key part of the shoe's waterproofing, and water vapor or rainwater can easily penetrate into the shoe through the gaps at the connection, thus affecting the waterproof performance of the shoe.

[0041] Working principle: When it is necessary to connect the sole 11 and the upper 1, the worker aligns the round rod 3 fixedly installed on the upper 1 and the connecting strip 2 with the limiting groove 5 opened on the sole 11, applies a pressure perpendicular to the sole 11, and pushes the round rod 3 into the circular groove of the limiting groove 5. When the cue stick 4 contacts the wedge-shaped entrance of the limiting groove 5, due to the thrust of the spring 41 in the slide groove 31, the cue stick 4 will slide outward and eventually be stuck by the geometry of the wedge-shaped surface, locked at the narrower locking end. At this time, the upper 1 and the sole 11 are firmly connected together. At the same time, as the upper 1 and the sole 11 approach each other, the silicone sealing ring 7 fixed below the connecting strip 2 will be compressed. Its inner wall forms a sliding fit with the outer surface of the round rod 3 and tightly fits the edge of the connection to complete the seal. The user can pass the shoelaces or ropes through the rope hole 6 and tie or knot them around the rope hole 6 to tighten and fix the upper 1 on the foot.

[0042] When it is necessary to release the fixation between the sole 11 and the upper 1, a sufficiently large external force is applied to overcome the thrust of the spring 41 and the huge locking force generated by the wedge locking surface, so that the cue stick 4 stuck at the wedge locking end is released from the locked position. The cue stick 4 is squeezed and contracted by the limiting groove 5, allowing the round rod 3 to be pulled out from the circular groove of the limiting groove 5.

[0043] 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.
