Description

Technical Field

[0001] The utility model relates to the field of sheaths, in particular to an airbag sheath. Background Art

[0002] In the prior art, people put protective covers on their elbows or knees during exercise to improve their protective ability. For example, the Chinese patent with the authorization announcement number CN209865247U discloses a sports cover with skin care and anti-collision functions. The rubber plate, airbag body and protective shell are used together to greatly reduce the impact force after the collision, solving the problems of the existing sports cover with insufficient anti-collision ability and lack of skin care ability. The gap between the strips enhances the air permeability of the airbag component, which reduces the feeling of stuffiness and improves the comfort for patients.

[0003] When the user wears the protective cover to exercise, since the user's elbows and knees are prone to bending, the traditional ball-shaped airbag cannot adapt well to the bending changes of the user's body, resulting in the airbag and the athlete's elbows or knees not being able to fully fit, reducing the protective effect, and when the airbag pressure is insufficient or ruptures, the entire airbag is scrapped, reducing the service life of the protective cover. Utility Model Content

[0004] The problem to be solved by the utility model is to provide an air bag cover which can prolong the service life and protect and fit the elbow or knee during exercise.

[0005] The utility model discloses an airbag cover, comprising a cover body, which is an elastic cloth cover, comprising a front cloth and a back cloth, a protective block in the middle of the front cloth, the protective block comprising a plurality of airbag bags evenly distributed and fixed in the middle of the front cloth, the airbag bag having an opening, and comprising a plurality of airbag units, the airbag units being detachably arranged inside the airbag bag, the protective block being in a dumbbell shape, the airbag bag being in a long strip shape, the airbag bag being perpendicular to the axis of the protective block, the axis of the protective block being consistent with the length direction of the front cloth, and the airbag unit being matched with the airbag bag.

[0006] As a specific scheme of the above technical scheme, the airbag unit placed in the middle of the protective block includes a long airbag and a connecting strip. The end of the long airbag is integrally formed with the connecting strip, and the opening is placed at the end of the length direction of the airbag bag. The long airbag and the connecting strip are both made of thermoplastic polyurethane elastomer rubber. Velcro is provided on the connecting strip, and Velcro that is compatible with the Velcro is provided inside the airbag bag.

[0007] As a specific scheme of the above technical scheme, the airbag unit placed at both ends of the protective block includes a tandem airbag and a connecting strip formed by connecting small square airbags in series. One side of the tandem airbag is integrally formed with the connecting strip, and the opening is placed on the side in the length direction of the airbag bag. The tandem airbag and the connecting strip are both made of thermoplastic polyurethane elastomer rubber. Velcro is provided on the connecting strip, and Velcro compatible with the Velcro is provided inside the airbag bag.

[0008] As a further improvement of the above technical solution, the airbag unit is provided with an inflation port connected to the airbag cavity.

[0009] As a further improvement of the above technical solution, the front cloth and the rear cloth of the sheath body are combined to form a cylindrical sheath.

[0010] As a specific solution of the above technical solution, the airbag unit 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.

[0011] As a further improvement of the above technical solution, the diaphragm is a TPU diaphragm, 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, and a connecting part is provided between two opposite connection points on the two diaphragms.

[0012] As a further improvement of the above technical solution, the connecting portion is a colloid arranged at the connecting points of the two membranes, and the two connecting points are thermally fused together by the colloid.

[0013] As a further improvement of the above technical solution, the connecting portion includes a protrusion that is integrally formed by injection molding with one of the diaphragms, and one end of the protrusion away from the diaphragm connected thereto is hot-pressed together with the other diaphragm.

[0014] Beneficial effects of the utility model:

[0015] This solution provides a protective block in the middle of the front cloth. The protective block has airbag units distributed in a dumbbell shape, which can adapt to the bending state formed by the elbow movement of the user during exercise, so that the airbag unit fits the bent part to ensure its protective effect.

[0016] (1) This solution provides a plurality of detachable airbag units, and can replace airbags with different bearing capacities according to different needs of users. The airbag cover fits the user more closely, making it suitable for the impact bearing requirements of sports protection of different intensities, thereby improving the applicability of the airbag cover.

[0017] (2) This solution provides a plurality of detachable airbags. When an airbag at one location ruptures, the corresponding damaged airbag can be replaced, so that the airbag cover can continue to be used, thereby extending its service life.

[0018] (3) TPU film is a film made from TPU granules through special processes such as calendering, casting, film blowing, and coating. It has a thickness of 0.01 to 2 mm, good elasticity, and outstanding high tension, high tensile force, strong toughness, and aging resistance. The diaphragm is made of TPU diaphragm, which makes the airbag have the advantages of high tension, high tensile force, strong toughness, and aging resistance. BRIEF DESCRIPTION OF THE DRAWINGS
