Novel zipper

Technical Field

The application relates to the technical field of clothing sewing articles, in particular to a novel zipper.

Background

At present, the zipper is widely applied to the fields of clothing sewing articles, bags and the like. However, in the related art, the conventional slide fastener has a simple coupling manner of the pull tab and the slider, and only one contact point therebetween is stressed. This makes the conventional slide fastener susceptible to the occurrence of the pull-tab breakage during use.

In view of the above-mentioned related art, the inventors consider that the conventional slide fastener is liable to the occurrence of the breakage of the tab, resulting in the reduction of the life of the slide fastener.

SUMMERY OF THE UTILITY MODEL

In order to prolong the service life of the zipper, the application provides a novel zipper.

The application provides a novel zip fastener adopts following technical scheme:

a novel zipper comprises a zipper body, a top plate connected with the zipper body in a sliding manner, a bottom plate connected with the zipper body in a sliding manner, a supporting plate vertically connected between the top plate and the bottom plate and a zipper handle rotationally connected with the top plate; one end of the zipper handle is provided with a rotary joint; the upper surface of roof is equipped with the boss, has seted up rotatory hole on two sides of boss, and rotary joint forms swivelling joint with rotatory hole.

Through adopting above-mentioned technical scheme, can realize the swivelling joint of zip fastener handle and roof. The connecting mode of the rotary connection can limit the zipper handle, so that the zipper handle cannot deviate towards one side. When the zipper handle is pulled, the number of stress points of the zipper handle is two. The increase of the stress points reduces the load born by a single stress point, and avoids the damage of the zipper handle, thereby achieving the effect of prolonging the service life of the zipper.

Optionally, the chain body includes a sewing cloth, a waterproof layer arranged on the surface of the sewing cloth, and a zipper tooth arranged on one side of the sewing cloth.

Through adopting above-mentioned technical scheme, sew up cloth and will draw the zipper tooth to couple together and form the chain body, sew up the waterproof layer of cloth both sides and can make the whole leakproofness of zip fastener better to make the novel zip fastener in this application prevent wind waterproof performance and obtain promoting.

Optionally, the zipper teeth comprise a rectangular tooth root and an elliptical tooth tip; the width of the tooth top is larger than that of the tooth root.

Through adopting above-mentioned technical scheme, the flank of tooth area of contact can be increased to oval-shaped addendum, and the addendum width is greater than the dedendum width and can lets the transverse load that every zip fastener tooth can bear bigger. The profile of tooth design of zip fastener tooth can let the novel zip fastener in this application bear bigger horizontal pulling force to make the zip fastener be difficult to after closed by tearing open.

Optionally, the edges of the two sides of the top plate and the bottom plate are symmetrically provided with protrusions.

Through adopting above-mentioned technical scheme, at the in-process of pulling the zip fastener handle, the arch at roof and bottom plate edge can extrude the zip fastener tooth, makes the zip fastener tooth mesh in proper order, finally makes the zip fastener closed. The bulge enables the opening of a gap formed by the top plate and the bottom plate to be smaller, so that the zipper is not easy to be clamped by clothes in the pulling process of the zipper.

Optionally, the rotation hole is formed at one end of the boss close to the support plate.

Through adopting above-mentioned technical scheme, can make the pulling force action point that the roof received in the top of backup pad and roof junction to make the roof be difficult to appear warping at the in-process that the zip fastener opened and shut, reduced because the roof warp and cause the not tight condition of zip fastener tooth meshing to appear.

Optionally, the cross section of the support plate is triangular.

Through adopting above-mentioned technical scheme, can make the area of contact increase between backup pad and roof and the bottom plate, make the roof can bear bigger pulling force and not produce deformation or fracture. The structural design of the triangular cross section can also ensure that the resistance received when the zipper slides along the direction of opening the zipper is smaller, thereby achieving the effect of saving more labor when in use.

Optionally, the zipper handle comprises a rotary joint, a handle body with one end connected with the rotary joint, and a pull ring arranged at the other end of the handle body.

Through adopting above-mentioned technical scheme, establish the rotary joint of handle body one end and establish the rotatory hole on the roof and form swivelling joint. The pull ring arranged at the other end of the handle body can play a role of convenient grasping, and the commodity label, the decorative strip and the like can be tied on the pull ring, so that the effect of enriching the use functions of the zipper is achieved.

Optionally, the tab is bent upwardly in a direction away from the handle body.

Through adopting above-mentioned technical scheme, the pull ring is at the terminal perk of handle body, and the effect that gripping is convenient, be difficult to skid when can reaching pulling zipper handle.

In summary, the present application includes at least one of the following beneficial technical effects:

1. the sliding connection design of the zipper handle and the top plate can increase the number of stress points and reduce the load borne by a single stress point, so that the service life of the zipper is prolonged;

2. the structural design of the supporting plate in the application can ensure that the resistance applied to the zipper in the opening process is smaller, and the effect of saving more labor in use is achieved;

3. the condition that the in-process that the zip fastener was opened and shut can be difficult to appear skidding by the structural design of the zip fastener handle in this application.

Detailed Description

The present application is described in further detail below with reference to figures 1-3.

At present, the common zipper is easy to break in the using process due to the simple connecting mode of the pull handle and the zipper head and the single stress point. In order to enable the pull handle to be connected with the zipper head more firmly so as to achieve the purpose of prolonging the service life, the embodiment of the application discloses a novel zipper.

The embodiment of the application discloses a novel zipper. Referring to fig. 1, the novel slide fastener includes a fastener body 1, a top plate 2, a bottom plate 3, a support plate 4, and a fastener handle 5.
