Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The core of the utility model is to provide a resilience pull head, all kick-backs under arbitrary angle, avoided the pulling-on piece to lose lock and jamming effectively.

The utility model discloses a another core provides a clothing and a case and bag including above-mentioned resilience pull head.

Please refer to fig. 1-6.

The utility model provides a resilience pull head, including horse hook 1, pulling-on piece 2 and pull head main part 3, pulling-on piece 2 includes pulling-on piece main part, horizontal pole 21 and horizontal pole bump 22, the central water flat line of horizontal pole 21 and the bottom surface nonparallel of pulling-on piece main part, and the bottom surface of horizontal pole bump 22 is no longer than the bottom surface of pulling-on piece main part.

It should be noted that the horizontal line at the center of the crossbar 21 refers to the center line of the cross bar 21 at a point farthest from the pull-tab body in the middle plane, as shown in fig. 6.

The included angle between the horizontal line of the center of the cross rod 21 and the bottom surface of the pull piece main body is not limited, as long as the surface of the cross rod 21 and the surface of the pull piece main body are not coplanar and not parallel, and the specific included angle between the horizontal center line of the cross rod 21 and the bottom surface of the pull piece main body is determined according to the actual production requirement.

Preferably, referring to fig. 4, the upper end face of the cross bar 21 may be arranged at an angle of 30 ° to 65 ° to the normal of the bottom face of the pull tab body, so as to obtain a good spring-back effect.

In addition, compare in the median plane of horizontal pole 21, the up end of horizontal pole 21 is controlled more easily in the course of working, and the contained angle of the normal of the up end of control horizontal pole 21 and the bottom surface of pulling-on piece main part is convenient for process and preparation.

The structure, shape, size, material and the like of the horse hook 1 and the slider body 3 are determined according to actual production needs by referring to the prior art, and are not described again; the material of the pull tab 2, the structure, the shape, the size and the like of the pull tab main body are determined according to actual production needs by referring to the prior art, and are not described in detail herein.

The bottom surface of the cross bar salient point 22 is not more than the bottom surface of the zipper-pull main body, so that the contact area between the cross bar salient point 22 and the horse hook 1 is reduced, and further the friction force between the cross bar salient point 22 and the horse hook 1 is reduced.

After the external force is removed, referring to fig. 6, when the pull tab rebounds to be perpendicular to the pull tab body, because the central horizontal line of the cross bar 21 is not parallel to the bottom surface of the pull tab body, the pressure of the cross bar 21 on the horse hook 1 is upward along the central horizontal line of the cross bar 21, and the friction force is reduced compared with that of a conventional rebounding slider, the pull tab 2 cannot maintain stable stress in a perpendicular state, and therefore the pull tab 2 can still rebound in the perpendicular state.

When the pulling-on piece 2 rebounds to the front of the pulling head main body 3, the bottom surface of the pulling-on piece 2 is in contact with the upper bottom plate 32 of the pulling head main body 3, the hook 1 is inserted into the hook clamping opening 33, the sliding of the pulling head main body 3 relative to the zipper is limited, and the locking of the rebounding pulling head is realized.

Therefore, the rebounding slider provided by the embodiment can rebound at any angle, and the slider is effectively prevented from losing lock and being stuck.

The overall shape of the pull tab 2 is not limited, and preferably, referring to fig. 4, the pull tab 2 can be configured as a square piece with a relatively regular shape, which is convenient for manufacturing and production.

Preferably, the crossbar bosses 22 may be located on the axis of the tile.

Preferably, in order to further reduce the friction force of the rail convex point 22 and the horse hook 1, the height of the rail convex point 22 can be set to gradually decrease from the connecting end relatively close to the rail 21 to the free end relatively far from the rail 21, so as to reduce the area of the free end of the rail convex point 22 for contacting the horse hook 1.

In order to facilitate the processing of the rail protruding points 22, it is preferable that the cross-section of the rail protruding points 22 is trapezoidal, as shown in fig. 5. The length of the shorter side of the trapezoid can be set to the mold opening limit size to reduce the contact area of the rail protruding point 22 and the horse hook 1 as much as possible.

Of course, the surface of the rail protruding point 22 may be a smooth arc surface.

On the basis of the above embodiment, please refer to fig. 5, the height of the cross bar 21 can be set to gradually decrease from the connecting end relatively close to the pull-tab body to the free end relatively far away from the pull-tab body, so as to reduce the contact area between the cross bar 21 and the upper bottom plate 32 of the slider body 3, further reduce the friction force between the cross bar 21 and the upper bottom plate 32, destroy the stable stress state of the pull-tab 2 in the vertical state, and avoid the pull-tab 2 from being stuck in the vertical state.

The specific size of the free end of the cross rod 21 is determined according to the actual production requirement, and preferably, the height of the free end of the cross rod 21 can be set to be the opening limit size.

Preferably, referring to fig. 5 and 6, the bottom surface of the cross bar 21 and the bottom surface of the cross bar salient point 22 may be coplanar, so as to simplify the structure of the pull tab 2 and reduce the mold opening cost.
