Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Example 1 referring to fig. 1-3, this example discloses a stretch band that is less prone to damage, consisting of a non-elastic band 1, an elastic band 3, a covering 2 and a restraint body 22.

The 2 sections of the non-elastic belts 1 are positioned at two sides, and the outer side end of each non-elastic belt 1 is folded and fixed to form a pull ring 11 for being pulled by a user conveniently.

As shown in fig. 3, the inner end of the 2-segment inelastic strap 1 is folded downward, the inner end forms a connecting end 12, the connecting end 12 is used for connecting with the sheath body 2, the joint of the two is used as a first joint 4, the folded part forms a corner part 13, and the area between the corner part 13 and the connecting end 12 is naturally attached to the bottom layer of the inner end of the body of the inelastic strap 1 to form a folded storage layer for storing the extension length of the inelastic strap 1 in the stretching process.

Furthermore, the inner side of the 2 sections of the non-elastic belts 1 is provided with the elastic belt 3, the elastic belt 3 is used as a main elastic expansion body, and by utilizing the elasticity characteristic of the elastic belt, when the non-elastic belts 1 on two sides are pulled outwards at the same time, the elastic belt 3 is stretched in a tensile way, the outward pulling action is released, and the elastic belt 3 rebounds inwards, contracts and resets. The joints between both ends of the elastic band 3 and the inelastic band 1 serve as second joints 5, and the second joints 5 are located in the outer regions of the corner portions 13.

The non-elastic belt 1 in this embodiment is specifically a woven belt made of woven threads made of nylon, and in other embodiments, a non-woven fabric or a breathable cotton layer may be used. The elastic band 3 in this embodiment is made of rubber.

Further, as shown in fig. 1 and fig. 2, a hollow sleeve body 2 is arranged between 2 sections of the inelastic belt 1, two ends of the sleeve body 2 are provided with openings 21,2, the inner ends of the sections of the inelastic belt 1 extend into the inner side of the sleeve body 2 from the openings 21, and are folded and fixed on the inner side wall of the sleeve body 2, and the connection position is the first connection position 4. In this embodiment, the first joint 4 and the second joint 5 are both fixedly connected by a sewing needle thread, and at least two sewing needle threads are sewn.

It should be noted that, the material of the sleeve body 2 in this embodiment is the same as the material of the non-elastic band 1, and has no elasticity, and in other embodiments, the elastic material may be adopted to make the stretching band have two elastic elements, namely the elastic band 3 and the sleeve body 2, so that the stretching band can have two-stage stretching strength by the overall design of length and stretching stroke, and the product functions are enriched.

Further, as shown in fig. 2, two constraining bodies 22 are arranged in the sleeve body 2, two ends of the constraining bodies 22 are fixedly connected with the inner side wall of the sleeve body 2, the non-elastic belt 1 is folded and wound at the inner side end of the constraining body 22, and the corner part 13 is located at the inner side of the constraining body 22. In this embodiment, the constraining body 22 is a non-elastic rope, which is mainly used to constrain the position of the corner portion 13, so that the extending and retracting path of the non-elastic belt 1 has a guiding pivot. In other embodiments, the restraining body 22 may be a metal rod, a plastic rod, or the like.

In the specific implementation process, with reference to fig. 4, in a free state, both ends of the elastic band 3 are fixed to the outer side region of the corner portion 13 of the inelastic band 1, when both sides pull the inelastic band 1 outwards, the inner region of the inelastic band 1 and the elastic band 3 extend outwards synchronously, specifically, the inelastic band 1 which is originally located inside the corner portion 13 and in the folded and stored state moves outwards after passing through the constraining body 22, the action is generated by following the outward movement of the outer fixed end of the elastic band 3, and when a user releases and stops the outward pulling action, the elastic band 3 can synchronously drive the inner region of the inelastic band 1 to reset inwards. This in-process, the cover body 2 can play the parcel effect, wraps up the folding part of inelastic strap 1 and the stretching of elastic strap 3, can play the effect of accomodating, avoids this structure mixed and disorderly, hijacks or colludes the drawing to limbs, influences normal tensile action, also reduces the potential safety hazard.

Example 2, the difference from example 1 is that: in the embodiment, two sleeve bodies 2 are included, as shown in fig. 5, the two sleeve bodies 2 are distributed at intervals, an upper opening 21 and a lower opening 21 are formed between the two sleeve bodies 2, the front side and the rear side of the two sleeve bodies 2 are still connected, the elastic band 3 between the two sleeve bodies 2 is exposed at the upper end and the lower end, and the sleeve bodies 2 only wrap the folded part of the non-elastic band 1. The structure enables the tensile strain of the elastic belt 3 to be clearer and more direct, and can also reduce the influence of the inner side wall of the sleeve body 2 on the friction force generated by the stretching of the elastic belt 3, so that the stretching action is smoother.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
