Description

Technical Field

[0001] The utility model relates to the technical field of injection-molded shoes, and more particularly to a pair of anti-skid injection-molded shoes. Background Art

[0002] Injection molding is a shoemaking process, also known as injection-molded shoes. This involves injecting thermoplastic into a shoe mold using an injection molding machine. After being subjected to high temperature and high pressure, the mold cools and solidifies, forming the final product. This process is primarily used to produce various plastic footwear, such as sandals, slippers, and sneakers. Injection-molded shoes are typically lightweight, waterproof, and easy to clean, offering high production efficiency and relatively low costs, making them widely used in the footwear industry.

[0003] The Chinese patent announcement number CN221179506U discloses a wear-resistant injection-molded shoe, which is provided with a heel layer. When the user wears the injection-molded shoe, the rubber block at the bottom of the wear-resistant sole will reduce the friction between the sole and the ground to a certain extent. At the same time, the wear-resistant pattern can increase the friction of the sole, and to a certain extent, reduce the damage to the sole caused by reducing friction. The protective surface of the heel layer will further protect against external wear, and the elastic rope will reduce the possibility of the protective surface breaking due to long-term wear to a certain extent. At the same time, the PVC-coated Oxford cloth material of the first wear-resistant layer and the second wear-resistant layer has the advantages of not being easily corroded, strong heat resistance, waterproof and flame retardant, cold and mildew proof, etc., and has good wear resistance, further improving the wear resistance of the injection-molded shoe upper and increasing the service life of the injection-molded shoe.

[0004] Injection-molded shoes are primarily made of soft plastic materials like PVC, TPR, or PU. These materials are less wear-resistant than rubber soles and are prone to hardening and breaking, especially in cold weather. Shoes with damaged soles are unwearable, but the uppers are still in good condition, resulting in waste. Therefore, it is necessary to provide anti-slip injection-molded shoes to address this issue.

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0036] Based on this, the problem in the related art that the soft plastic material used in injection molding has poor wear resistance compared to rubber soles can be improved. Especially in cold weather, it is easy to harden and break the soles. Shoes with damaged soles can no longer be worn, but the uppers are still good, which easily leads to waste.

[0037] See also Figure 1-Figure 5 A non-slip injection-molded shoe includes an upper 1, a heel 3 and a sole 4. The bottom end of the upper 1 is fixedly connected to a bottom plate 7. The upper 1 and the heel 3 are integrally formed. The outer end of the heel 3 is fixedly connected to a rear clamping block 10. A connecting component 8 is provided at the top of the sole 4. A limiting component 9 is provided at the outer end of the connecting component 8. The connecting component 8 is detachably connected to the upper 1 through the limiting component 9. The sole 4 includes an outsole 41 and a midsole 42. The outsole 41 and the midsole 42 are connected by glue. The connecting component 8 includes a connecting bottom 81. The outer end of the connecting bottom 81 is fixedly connected to a rear pull-out block 82. The bottom end of the connecting bottom 81 is connected to the midsole 42.

[0038] The inner side of the connecting bottom 81 is fixedly connected with the abutting plate 5 , and the bottom plate 7 abuts against the abutting plate 5 . A slot 6 is defined on the inner side wall of the connecting bottom 81 , and the outer end of the bottom plate 7 is fixedly connected with a front plug-in board 11 that matches the slot 6 .

[0039] Side skirts 85 are fixedly connected to both sides of the connecting bottom 81 , air cushions 12 are installed on both sides of the upper 1 , and shoelaces 2 are provided at the outer ends of the upper 1 .

[0040] A connecting hole 84 is provided at the outer end of the rear pull block 82, which is adapted to the rear clamping block 10. A pull strap 83 is fixedly installed at the outer end of the rear pull block 82. The connecting bottom 81, the rear pull block 82 and the side skirt 85 are integrally formed.

[0041] The injection-molded shoes in this solution differ from traditional one-piece shoes. The sole 4 and upper 1 are detachably connected via a connecting assembly 8 and a limiting assembly 9. Unlike traditional uppers 1, which have a hollow bottom surface, the upper 1 in this solution has a complete bottom surface. The upper 1 and heel 3 are integrally molded, with shoelaces 2 provided at the outer end of the upper 1. The bottom end of the upper 1 is fixedly connected to a base plate 7, which is glued to the bottom of the upper 1. A front insert 11 is secured to the outer end of the base plate 7, at the toe. The sole 4 consists of an outsole 41 and a midsole 42. The midsole 42 is made of PVC and injection molded, while the outsole 41 is made of rubber. The outsole 41 enhances the anti-slip properties and wear resistance, improving the overall structural strength of the sole 4.

[0042] The upper 1 in this solution is connected to air cushions 12 on both sides of its bottom, that is, the arch of the foot. The air cushions 12 are connected to the upper 1 by glue. When the upper 1 and the sole 4 are connected together, the air cushion 12 will be located between the connecting bottom 81 and the upper 1. By squeezing the air cushion 12, the gap between the upper 1 and the arch of the foot of the connecting bottom 81 can be filled, thereby increasing the sealing. At the same time, the air cushion 12 can also support the side of the arch of the foot to give it better stability. Two side skirts 85 are also fixed at the heel of the connecting bottom 81. The two side skirts 85 extend inward so that the two side skirts 85 can rest on both sides of the heel 3 on the upper 1. It is mainly through the squeezing of the side skirts 85 that the sealing of the connection between the heel 3 and the connecting component 8 is increased, thereby cooperating with the air cushion 12 to increase the sealing and connection strength when the upper 1 is installed on the connecting component 8.

[0043] The connecting component 8 is fixed on the top of the midsole 42, and the limiting component 9 is provided on the inner side of the connecting hole 84. The bottom plate 7 can be inserted into the slot 6 opened on the inner side of the connecting bottom 81 through the front plug-in plate 11 fixed at the outer end, so as to fix the front part. The rear clamping block 10 is fixed on the heel 3, and the rear clamping block 10 is clamped on the limiting block 91 through the clamping groove 13 opened at the bottom, so as to fix the heel. At the same time, the upper 1 is against the connecting bottom 81 through the air cushions 12 on both sides, and the side skirt 85 is against the heel of the upper 1, so as to strengthen the connection strength. Through the detachable connection between the upper 1 and the sole 4, when the sole 4 is damaged, it can be disassembled and replaced, so that the upper 1 can be reused, thereby improving the utilization rate.

[0044] Optionally, in some embodiments, see Figure 3-Figure 5 The limiting assembly 9 includes a limiting block 91 , a movable groove is provided on the inner wall of the connecting hole 84 , and a slider 92 is fixedly connected to the bottom end of the limiting block 91 .

[0045] The limit block 91 is slidably connected to the movable groove through a slider 92 . A clamping slot 13 adapted to the limit block 91 is provided at the bottom end of the rear clamping block 10 . A shift rod 93 is fixedly connected to the outer end of the slider 92 .

[0046] A sliding groove communicating with the movable groove is provided at the outer end of the rear pull block 82 , the shift rod 93 is slidably connected to the sliding groove, and two telescopic springs 94 are fixedly connected to the bottom end of the slider 92 .

[0047] In this solution, the connecting bottom 81 is bonded to the midsole 42 by glue, and a rear pull block 82 is fixedly connected to the heel of the connecting bottom 81. The rear pull block 82, the connecting bottom 81 and the side skirt 85 are integrally formed. A connecting hole 84 is provided at the outer end of the rear pull block 82, and a rear clamping block 10 is fixed to the outer end of the heel 3. The size of the connecting hole 84 matches that of the rear clamping block 10. A slot 6 is provided on the inner wall at the toe of the connecting bottom 81. The slot 6 matches the front insert plate 11 on the bottom plate 7. When the front insert plate 11 is inserted into the slot 6, it can be clamped. An abutment plate 5 is also fixed to the forefoot position of the connecting bottom 81 for abutting against the bottom plate 7 to support it.

[0048] The bottom inner wall of the connecting hole 84 is provided with a movable groove, and the outside of the movable groove, that is, the outer end of the rear pull block 82, is provided with a slide groove, which matches the movable groove, and the limit block 91 is located inside the movable groove, and the bottom end of the limit block 91 is fixedly connected to the slider 92, and the limit block 91 is slidably connected to the movable groove through the slider 92. At the same time, the top of the limit block 91 is provided with an inclined surface, and two telescopic springs 94 are fixed at the bottom end of the slider 92. The telescopic spring 94 is located inside the movable groove and the bottom end is connected to the movable groove. A detent rod 93 is fixed at the outer end of the slider 92, and the detent rod 93 extends through the slide groove to the outer end of the rear pull block 82. The slider 92 can slide up and down in the movable groove driven by the detent rod 93, and a pull belt 83 is also fixed at the outer end of the rear pull block 82, and the rear pull block 82 can be driven to bend backward by pulling the pull belt 83.

[0049] When the upper 1 and the sole 4 need to be connected together through the connecting assembly 8 and the limiting assembly 9, the upper 1 needs to be worn on the foot alone. At this time, the front insert plate 11 is inserted into the slot 6 on the connecting bottom 81 through the bottom plate 7. The front insert plate 11 will extend into the slot 6, thereby locking the front insert plate 11. Then, the sole 4 is placed on the ground, with the toes touching the ground first, and then the heel is slowly moved downward to make the bottom plate 7 fit with the abutment plate 5. Then, the drawstring 83 is pulled backward to bend the rear pull block 82. When the heel 3 fits with the rear pull block 82, the rear clamping block 10 at the outer end of the heel 3 will be clamped into the connecting hole 84. When the shoe is taken off, the lever 93 can be pressed downward to move the limit block 91. At the same time, the drawstring 83 can be pulled to bend the rear pull-out block 82 so that the rear pull-out block 82 will not fit the heel 3, thereby separating the sole 4 from the upper 1.

[0050] Working principle: When the upper 1 and the sole 4 need to be installed together, first insert the front insert plate 11 into the slot 6 on the connecting bottom 81 through the bottom plate 7, clamp the front insert plate 11, then touch the ground with the toes first and then slowly move the heel downward, then pull the drawstring 83 backward to bend the rear pull block 82, and the rear clamping block 10 will be clamped into the connecting hole 84. At this time, the clamping block 10 will abut against the inclined surface on the limit block 91, and the limit block 91 will be squeezed downward. When the limit block 91 enters the inside of the card slot 13, it will clamp the rear clamping block 10, so that the rear clamping block 10 and the limit assembly 9 are connected together, thereby completing the connection, and the upper 1 is on the foot. Air cushions 12 are connected on both sides of the arch. By squeezing the air cushions 12, the gap between the upper 1 and the arch part of the connecting sole 81 can be filled to increase the sealing. At the same time, the side of the arch is supported to make it have better stability. Two side skirts 85 are also fixed at the heel of the connecting sole 81, which can be pressed against the two sides of the heel 3 on the upper 1 to increase the sealing of the connection between the heel 3 and the connecting component 8. When it needs to be taken off, the lever 93 can be pressed downward to drive the limit block 91 to move downward. At the same time, the drawstring 83 needs to be pulled to bend with the pull block 82, thereby separating the sole 4 and the upper 1.
