Description

Technical Field

[0001] The utility model relates to the technical field of protective gear, in particular to a thermal insulation protective gear. Background Art

[0002] Knee pads are a type of equipment used to protect the knee joints and are widely used in sports, work, and daily life. They are usually made of materials such as elastic fabrics, foam, rubber, or plastic, and are designed with good support and cushioning properties. They can effectively absorb impact and reduce damage to the knees during sports or work. Knee pads come in a variety of styles, including full-cover, half-cover, and open styles, suitable for different activities. Whether it is intense sports such as basketball and football, or daily walking, suitable knee pads can provide additional protection and reduce the risk of injury. In addition, the design of knee pads also pays more and more attention to comfort and aesthetics, making them not only practical, but also integrated into fashion wear.

[0003] Generally speaking, the current knee pads include a fixed sleeve, an outer cover sewn on the outside of the fixed sleeve and located at the kneecap, and a cushioning filler filled between the fixed sleeve and the outer cover. Generally speaking, the outer cover has a certain hardness to protect the knee of the user when wearing the knee pad. However, the hard outer cover will cause a certain degree of hindrance to the user's leg movement. Therefore, the outer cover is now converted into a fabric similar to the fixed sleeve to limit the cushioning filler. However, facing the current knee pads made of completely soft fabrics, both the fixed sleeve and the outer cover are relatively thin, and their barrier and cushioning effects are poor.

[0004] Therefore, a thermal insulation protective gear is proposed to solve or alleviate the above problems. Utility Model Content

[0028] A thermal insulation protector, such as Figure 1As shown, it includes a fixed sleeve 1, an outer cover 2 fixedly connected to the outside of the fixed sleeve 1 through an edge seal 3, and a buffer filler filled between the outer cover 2 and the fixed sleeve 1, wherein the buffer filler is a sponge pad, such as Figure 2 As shown, the fixing sleeve 1 and the outer cover 2 both include a surface layer 401 and a contact layer 402, and a plurality of support portions 403 fixedly connected between the surface layer 401 and the contact layer 402 and evenly spaced apart. The cross section of the support portion 403 is I-shaped and the support portion 403 is made of silicone.

[0029] like Figure 4 As shown, the contact layer 402 and the surface layer 401 are variable square basket weaves formed by weaving the warp and weft of composite yarns. The variable square basket weave has 7 pages and the warp floating points are floating and the weft floating points are sinking. The weaving cycle of the variable square basket weave from left to right and from top to bottom is: floating and sinking, floating and sinking, floating and sinking, floating and sinking, floating and sinking, floating and sinking, floating and sinking, floating and sinking, floating and sinking, floating and sinking, floating and sinking, floating and sinking, floating and sinking, floating and sinking, floating and sinking, floating and sinking.

[0030] And as Figure 3 As shown, the composite yarn includes a core wire 501 and a plurality of outer wires 502 that are spirally wound around its outer ring. The core wire 501 is twisted by a plurality of special-section polyester fibers 5011, and the cross-section of the special-section polyester fibers 5011 is C-shaped. The outer wires 502 are twisted by a plurality of hollow nylon fibers 5021.

[0031] In actual production, the utility model obtains a C-shaped cross-section polyester fiber 5011 and a hollow nylon fiber 5021 through a spinning process, and twists a plurality of the special-shaped cross-section polyester fibers 5011 through a twisting machine to obtain a core wire 501, twists a plurality of the hollow nylon fibers 5021 to obtain an outer wire 502, and then parallels a core wire 501 with eight outer wires 502, requiring that the core wire 501 is located in the middle and the eight outer wires 502 are located on the outer ring of the core wire 501, and then twists the core wire 501 and the outer wire 502 through a twisting machine to obtain a composite yarn, and the composite yarn is subsequently fed into a water jet loom, and the water jet loom is assembled according to the above-mentioned changes. The woven structure is woven through the weft and the yarn is sprayed to complete the weaving of the composite yarn, and a piece of fabric with good elasticity and fluffy feeling is obtained. The fabric is cut to obtain the surface layer 401, the contact layer 402, the outer cover 2, and the edge sealing 3. The buffer filler is then clamped between the outer cover 2 and the surface layer 401, and the edge sealing 3 is used to cooperate with the outer cover 2 to fix the outer cover 2 by a seamless bonding process, thereby setting the buffer filler between the outer cover 2 and the surface layer 401, and the support part 403 with an I-shaped cross-section and made of silicone material is bonded between the surface layer 401 and the contact layer 402, and the two ends of the surface layer 401 and the two ends of the contact layer 402 are bonded by a seamless bonding process to obtain a fixed sleeve 1, and the final protective gear is also obtained at this time;

[0032] The protective device maintains good elasticity through the profiled-section polyester fiber 5011 in the core wire 501. Moreover, due to its special cross-sectional shape, it has a certain degree of fluffiness compared with ordinary polyester fibers. Similarly, the hollow nylon fiber 5021 is the same. Therefore, the structure of the composite yarn itself also remains relatively fluffy. At the same time, the setting of the hollow nylon fiber 5021 makes the outer surface of the composite yarn have better wear resistance, and its touch remains relatively smooth. For the fixing sleeve 1, the outer cover 2, and the edge sealing 3 formed thereby, problems of wear are not likely to occur during long-term use. In addition, the setting of the support part 403 makes the fixing sleeve 1 and the outer cover 2 both have a certain thickness. When the fixing sleeve 1 wraps around the outer side of the user's leg and the wrapped part touches the outside world, the support part 403 can block and buffer, and the space between adjacent support parts 403 can slow down the air flow speed, enabling the fixing sleeve 1 to effectively increase the heat preservation and heat insulation performance of the protective device to a certain extent. The contact layer 402 and the surface layer 401 with a changing plain weave can maintain the firm weaving and smooth touch of the fixing sleeve 1 while also forming certain pores for slow air flow, preventing the human skin covered by the fixing sleeve 1 from being too stuffy.

[0033] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
