Detailed Implementation
[0024] 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.
[0025] Example 1:
[0026] Please see Figures 1 to 6 This utility model provides a technical solution: an insulating shoe using a composite insulating layer, comprising a sole 1 and an upper 4. The top of the sole 1 is fixedly connected to an upper 2. The sole 1 is composed of a rigid layer 19, a first insulating layer 14, a second insulating layer 15, and a third insulating layer 16. From bottom to top, the sole 1 consists of a rigid layer 19, a first insulating layer 14, a second insulating layer 15, and a third insulating layer 16. The upper 2 is composed of a first insulating layer 14, a second insulating layer 15, a third insulating layer 16, and a fourth insulating layer 17. From outside to inside, the upper 2 consists of a first insulating layer 14, a second insulating layer 15, a third insulating layer 16, and a fourth insulating layer 17. The upper 4 is composed of a first insulating layer 14, a second insulating layer 15, a third insulating layer 16, and a fifth insulating layer 18. From top to bottom, the upper 4 consists of a first insulating layer 14, a second insulating layer 15, a third insulating layer 16, and a fifth insulating layer 18. The third insulating layer 16 and the fifth insulating layer 18, the hard layer 19 are made of natural rubber and are thicker than two centimeters. The first insulating layer 14 is made of polyurethane coated fabric and the thicknesses of the first insulating layer 14 inside the sole 1, the first insulating layer 14 inside the upper 2, and the first insulating layer 14 inside the upper 4 are 0.5 cm, 0.5 cm, and 1 cm, respectively. The second insulating layer 15 is made of polyurethane and is 1.5 cm thick. The third insulating layer 16 is made of silicone rubber and the thicknesses of the third insulating layer 16 inside the sole 1, the third insulating layer 16 inside the upper 2, and the third insulating layer 16 inside the upper 4 are 0.5 cm, 0.5 cm, and 1 cm, respectively. The fourth insulating layer 17 and the fifth insulating layer 18 are made of polypropylene V2400G and polypropylene X30G, respectively, and are both 1 cm thick. The top of the upper 2 is the fourth insulating layer 17.
[0027] In practice, existing oil- and stain-resistant safety shoes do not offer sufficient insulation, thus hindering foot protection for workers. Therefore, a composite insulation layer is used in this type of insulated shoe. The rigid layer 19, made of natural rubber and more than two centimeters thick, provides a degree of rigidity to the sole, preventing foot pain caused by stepping on hard objects. The first insulation layer 14, made of polyurethane-coated fabric, provides waterproofing and oil resistance to the outer edges of the upper 4 and the shoe upper 2. The second insulation layer 15, made of polyurethane and one and a half centimeters thick, provides breathability and wear resistance. The third insulation layer... The material of layer 16 is silicone rubber, which gives the inside of the insulated shoe sole 1 good flexibility, allowing the inside of the sole 1 to fit the sole of the foot. The materials of the fourth insulation layer 17 and the fifth insulation layer 18 are polypropylene V2400G and polypropylene X30G respectively, and both are one centimeter thick. This gives the inner wall of the shoe upper 2 and the bottom of the shoe upper 4 a certain degree of hardness. Due to their high chemical inertness, they can better contact the skin. The materials of the hard layer 19, the first insulation layer 14, the second insulation layer 15, the third insulation layer 16, the fourth insulation layer 17 and the fifth insulation layer 18 all have a certain degree of insulation, which greatly improves the insulation effect of the insulated shoe and protects the safety of workers' feet.
[0028] Example 2:
[0029] Please see Figures 1 to 6 This utility model provides a technical solution: an insulating shoe using a composite insulation layer. The top of the shoe upper 2 has a second slot 8 and four first slots 7. The second slot 8 is arc-shaped, and the first slots 7 are square. The bottom of the shoe upper 4 is fixedly connected to a second plate 11 and four first plates 10. The first plates 10 and 11 correspond to the shapes of the first slots 7 and 8, respectively. The second plates 11 and 8 are located at the front end of the shoe upper 4. The first plates 10 are distributed in pairs on the left and right sides of the bottom of the shoe upper 4. The outer end of the second plate 11 and the second slot 8 both have a first locking hole 12 penetrating through them. The first locking hole 12 is circular, and a second locking rod is slidably connected to its inner wall. 9. The length of the second locking rod 9 is greater than that of the first locking hole 12. Two second locking holes 13 are provided on the back of the shoe upper 4 and the second locking holes 13 are square. The two second locking holes 13 are symmetrically distributed on the left and right sides of the shoe upper 4. A third locking hole is provided on both the left and right rear sides of the shoe upper 2. A locking block 5 is slidably connected to the inner wall of the third locking hole. The locking block 5 is inclined U-shaped and a fixing plate is fixedly connected to the outer wall. The upper half of the locking block 5 is slidably connected to the second locking hole 13. The upper and lower ends of the locking block 5 are respectively adapted to the second locking hole 13 and the third locking hole. The fixing plate is located directly above the lower end of the locking block 5 and through holes are provided on the top of the fixing plate, the lower end of the locking block 5 and the top of the third locking hole. The through holes are circular and are slidably connected to the first locking rod 6.
[0030] When cleaning insulating shoes, due to their high rigidity, and the inability to flip the upper 4 of the cordless shoes, the inside of the toe cannot be cleaned effectively, which is not conducive to cleaning the insulating shoes. Therefore, there is a type of insulating shoe using a composite insulation layer. When the insulating shoes need to be cleaned, the upper 4 needs to be removed first. At this time, the second locking rod 9 is pulled out from the first locking hole 12, so that the front of the upper 4 can move up and down. Then, the first locking rod 6 is pulled out from the through hole from bottom to top. Then, the locking block 5 is pulled out from the second locking hole 13 and the third locking hole from front to back, so that the back of the upper 4 can move up and down. Finally, the upper 4 is moved upward as a whole, so that the first locking plate 10 and the second locking plate 11 are moved out of the first locking groove 7 and the second locking groove 8 respectively, thereby separating the upper 4 from the shoe upper 2, which allows for better cleaning of the inside of the insulating shoes.
[0031] 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.
