Description

Technical Field

[0001] The utility model relates to the technical field of sports protective gear, in particular to a cold and hot knee pad. Background Art

[0002] The knee, or patella, is an important joint in the human body. The connection between the femur, tibia and patella bears the main weight of the human body, especially during jumping and other sports, it has to withstand a lot of impact. Therefore, athletes' knees are easily injured. Common knee redness, swelling and pain caused by exercise can be relieved by ice compresses.

[0003] At the same time, there is almost no muscle covering the patella, only the fascia in the subcutaneous layer, and there is little subcutaneous fat, so there is no insulation layer, no subcutaneous fat, and no muscle at this position. Especially for the elderly, the knee position is most susceptible to invasion by wind, cold and dampness, causing cold and pain in the knee.

[0004] The patent document with the authorization announcement number CN215688945U discloses a bandage-type hot and cold compress physiotherapy care product, which includes an upper surface layer, a lower surface layer, an elastic gel pad, and a plurality of bandages. The outer periphery of the upper surface layer and the outer periphery of the lower surface layer are fixedly connected to form a skirt of an annular structure. An elastic gel pad is arranged in the hollow chamber between the upper surface layer and the lower surface layer, and a plurality of bandages are fixedly connected to the skirt. This solution has a simple structure and low cost. However, the elastic gel pad of this solution needs to be cooled or heated in advance, which is inconvenient to use.

[0005] Therefore, people made further improvements, and in the patent document with the authorization announcement number CN219020292U, a kind of ice knee pad was disclosed, which includes a bottom lining layer, a refrigeration component and an airbag component arranged on the inner side of the bottom lining layer, and a power supply module arranged on the outer side of the bottom lining layer for supplying power to the airbag component and the refrigeration component. This scheme arranges the refrigeration component and the airbag component on the bottom lining layer, so that when the ice knee pad is used, the refrigeration component applies ice to the knee joint. During exercise, the airbag component can not only squeeze the upper and lower muscles of the knee joint inward to achieve a better recovery effect, but also make the refrigeration component close to the knee joint to avoid separation between the two, thereby improving the ice effect.

[0006] When this solution is actually used, its cooling component actually contacts the thigh and calf, while the connection between the femur, tibia and patella cannot achieve the ice compress effect, so the ice compress effect on the knee is not good; in addition, its power supply module is set together with the knee pad, which increases the weight on the leg, and this solution does not disclose the connection structure between the cooling component and the knee pad.

[0007] Therefore, it is necessary to design a new structure to solve the above problems. Utility Model Content

The reinforcement ring 101 can be repeatedly sewn around the hot and cold component mounting hole 100 to form a non-elastic reinforcement ring 101 to improve the strength at the hot and cold component mounting hole 100.

[0026] A hot and cold component 2 is provided on the hot and cold component mounting hole 100 . The hot and cold component 2 has a mounting portion, which includes a protruding portion and a resisting portion. The hot and cold component 2 also has a contact portion for contacting the human body and a fixing part for fixing the hot and cold component 2 on the knee pad body 1 .

[0027] In this embodiment, Figure 5 and Figure 6As shown, the hot and cold assembly 2 includes a shell 20, the shell 20 has a mounting portion 21, the mounting portion 21 includes an extension portion 211 and a stopper portion 212, the extension portion 211 is a hollow cylindrical structure, and an external thread is provided on the outer surface of the extension portion 211; the stopper portion 212 is provided at the root of the extension portion 211, and the cross-sectional area of ​​the stopper portion 212 is larger than the cross-sectional area of ​​the extension portion 211; an anti-slip protrusion 213 is provided on the surface where the stopper portion 212 contacts the knee pad body 1.

[0028] The fixing member 22 is a circular ring structure. A retaining ring 222 corresponding to the resisting portion 212 is provided on one side of the fixing member 22 . An internal thread is provided on the fixing member 22 , and the internal thread cooperates with the external thread.

[0029] The hot and cold assembly 2 also includes a fan 23, a cooling fin 24 and a cover 25. The fan 23 and the cooling fin 24 are arranged in the shell 20. The cover 25 is buckled on the end of the extension 211. The cover 25 is in contact with the cooling fin 24. In order to improve the conduction effect of the cold amount, silicone grease can be applied between the cover 25 and the cooling fin 24.

[0030] The cooling sheet 24 can switch the direction of the cooling surface and the heating surface by switching the polarity of the positive and negative electrodes. When it is necessary to switch from cold compress to hot compress, it can be switched through the controller.

[0031] When installing the hot and cold component 2, the extending portion 211 of the hot and cold component 2 is passed through the hot and cold component mounting hole 100; the abutting portion 212 abuts against one side of the hot and cold component mounting hole 100, and the fixing piece 22 is rotated to make the retaining ring 222 of the fixing piece 22 abut against the other side of the hot and cold component mounting hole 100.
