Abstract
Description
Technical Field
[0001] The utility model relates to a sports protection device, in particular to a sports waist protector. Background Art
[0002] Sports waist protectors are used to prevent damage to the waist muscles and ligaments caused by excessive force during exercise. They generate appropriate binding force on the waist muscles to avoid passive stretching of the waist muscles and cause damage, and prevent damage to the lumbar spine caused by exercise. In the prior art, waist protectors often use Velcro and elastic bands to adjust the waist size and elasticity of the waist protectors. In order to keep the waist protectors close to the waist and abdomen, users often tighten the elastic bands. The tightened elastic bands have a tendency to shrink inward, thereby continuously exerting pressure on the waist and abdominal muscles and blood vessels. Long-term use is not conducive to the smooth breathing and blood circulation of athletes. For example, the Chinese utility model patent (patent number 201921263723, named "A Sports Waist Protector") discloses a sports waist protector, including a waist protector body, the waist protector body includes a rubber layer, and a surface layer is compositely arranged on the rubber layer. The rubber layer has strong elasticity, which protects the waist and abdomen while enhancing the sense of restraint of the waist and abdomen, which is not conducive to smooth blood circulation and breathing. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a sports waist protector which has moderate elasticity and can be adjusted.
[0004] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0005] A sports waist protector comprises a main body, which is a main body. The main body can be overlapped into a ring shape by an open-end zipper, and the open-end zipper comprises a left flexible toothed chain belt and a right flexible toothed chain belt. The left flexible toothed chain belt and the right flexible toothed chain belt are respectively sewn on the two ends of the main body, and the left flexible toothed chain belt and the right flexible toothed chain belt are meshed with each other. The thickness of the main body is 2.5-3 mm, and the Shore hardness is 10-15 degrees.
[0006] Beneficial effects: SBR, scientific name chloroprene rubber, is a synthetic rubber foam with delicate, soft, elastic feel, good elasticity, shockproof and thermal insulation properties. With the improvement of SBR synthesis methods in recent years, the cost of obtaining SBR has been continuously reduced. The main body of this technical solution is made of foamed SBR material. Experimental test data show that when the thickness of the main body is 2.5~3mm and the Shore hardness is 10~15 degrees, the main body has good softness; and when the pure stretching length of the main body is in the range of 2~7 mm, its material is in a slightly elastic state, and the restraining force applied to the muscles is sufficient to make the main body stable in the waist and abdomen without sliding down, and does not excessively press the waist and abdominal muscles inward. At this time, the comfort of using the sports waist protector is the best, and it can play a role in adjusting the force balance, protecting the waist joint, and strengthening muscle strength during the user's exercise process. It solves the problem in the prior art that the elastic band tied inside the sports waist protector has a tendency to shrink inward, thereby continuously exerting pressure on the waist and abdominal muscles and blood vessels, and long-term use is not conducive to the smooth breathing and blood circulation of athletes. The present invention also adopts an open-end zipper as a lap-and-fix method for the waist protector, rather than the Velcro lap-and-fix method of the prior art, which is easy to use and not easy to slip off.
[0007] As a further improvement of the above technical solution, there is 1 left flexible chain belt and n right flexible chain belts, n≥1, the open-end zipper is at an angle of 45° to 60° with the length direction of the body, and when the number of right flexible chain belts is greater than 2, adjacent right flexible chain belts are sewn in parallel to each other on the outer surface of the body. This improvement makes it possible that, in the overlapping meshing state, compared with the open-end zipper being at a vertical angle to the length direction of the body, the body has a larger stress concentration area at the open-end zipper, and the notch effect caused by stress concentration has a smaller impact on the open-end zipper, making it less likely to be broken by external force, and the overlapping effect is more stable. At the same time, this specific solution has a graded adjustment function, and athletes can choose to overlap the left flexible chain belt with the right flexible chain belt of different grades according to their own waist size to flexibly adjust the tightness of the sports waist protector.
[0008] As a specific solution of the above technical solution, the spacing between adjacent right flexible tooth chain belts is 5-8 mm.
[0009] As a further improvement of the above technical solution, it also includes a flannel lining that is sewn and fixed to the bottom surface of the body, and the elasticity of the flannel lining is the same as that of the body. This improvement makes the side of the waist protector that contacts the user's waist a flannel surface, which feels more comfortable.
[0010] As a further improvement of the above technical solution, it also includes an airbag and m open airbag bags sewn together with the surface of the main body, m≥1, and the airbag is adapted to the open airbag bags.
[0011] As a further improvement of the above technical solution, the open airbag bag opens upward.
[0012] As a specific solution of the above technical solution, the airbag includes two airtight membranes, the peripheries of the two membranes are heat-sealed together to form an airbag cavity, and the airbag cavity is filled with air or nitrogen.
[0013] As a further improvement of the above technical solution, a number of connection points are evenly distributed on the two diaphragms, and the connection points on the two diaphragms are opposite to each other. A connecting part is arranged between two opposite connection points on the two diaphragms. The connecting part is a colloid arranged at the connection points on the two diaphragms, and the two connection points are glued together by the colloid.
[0014] As a further improvement of the above technical solution, the airbag is provided with a sealed inflation port that can be opened and closed and is connected to the airbag cavity. One side of the airbag is provided with an integrally molded connecting strip. The airbag and the connecting strip are both made of thermoplastic polyurethane elastomer rubber. Velcro is provided on the connecting strip, and the inside of the airbag bag is provided with Velcro that is compatible with the Velcro.
[0015] As a specific solution of the above technical solution, the diaphragm is a TPU diaphragm. BRIEF DESCRIPTION OF THE DRAWINGS
