Detailed Description

In order to make the present invention clearer, the present invention will be further described with reference to the accompanying drawings.

Please refer to fig. 1-3, the utility model provides a prevent zipper head that fabric card was gone into, including last jam plate 1 of zip fastener, jam plate 2 and pulling-on piece 3 under the zip fastener, jam plate 2 links to each other through branch chain tooth 4 under the zip fastener and the zip fastener, be equipped with on the zip fastener on the jam plate 1 and draw nose 5, be equipped with the spout on drawing

nose

5, 3 front ends of pulling-on piece are equipped with two sliders, two slider symmetries set up to with spout swing joint, the front end of jam plate 1 is equipped with a rubber strip 6 on the zip fastener, be equipped with a recess on the rubber strip 6, in the recess was gone into to the front end card of jam plate 1 on the zip fastener, rubber strip 6 generally had the high elasticity, the characteristics of low modulus, the frictional wear performance of rubber is received self physical mechanical properties's. Because the hardness of rubber is less, when contacting with the fabric, the real contact area is larger, and the size of the real contact area is an important factor for determining friction, therefore, the friction force between the fabric and the zipper puller can be increased by arranging the rubber at the front end of the zipper plate, the zipper puller can be clamped by contacting with the fabric when sliding forwards, and a user can find out that the fabric is completely involved in the zipper puller.

In this embodiment, two sides of the upper zipper locking plate 1 are provided with symmetrical first guide strips 7, two ends of the lower zipper locking plate 2 are provided with symmetrical second guide strips 8, the upper zipper locking plate 1 is installed on the upper side surface of the zipper teeth 4, the two first guide strips 7 are far away from the zipper teeth 4, the two second guide strips 8 are correspondingly matched with the two second guide strips 8 installed on the lower zipper locking plate 2 one by one, a gap is arranged between the first guide strips 7 and the second guide strips 8, a cloth belt connected with the zipper teeth is arranged in the gap, the zipper teeth are arranged between the upper zipper locking plate 1 and the lower zipper locking plate, the zipper teeth on two sides are clamped by the zipper teeth 4, and the zipper teeth on two sides can be meshed or separated by sliding with the pull tab; the front end of the zipper upper lock plate 1 is an arc-shaped surface, the rubber strip 6 wraps the edge of the arc-shaped surface of the zipper upper lock plate 1, and the first guide strip 7 is arranged on the rear side of the rubber strip 6; the front end of the lower zipper locking plate 2 is also provided with a rubber strip 6 to prevent fabric from entering the interior of the zipper from the lower zipper locking plate 2, the distance between the rubber strip 6 and the lower zipper locking plate 2 is greater than the height of the zipper teeth, so that when the zipper head pulls the zipper teeth, the zipper teeth can be contacted with the inner side wall of the first guide strip 7 and the zipper teeth 4 but can not be directly contacted with the arc-shaped surface at the front end of the upper zipper locking plate 1 and the rubber strip 6, the phenomenon that the zipper teeth are clamped in the meshing process due to the fact that the friction force is increased when the rubber strip 6 is arranged on the arc-shaped surface at the front end of the upper zipper locking plate 11 is prevented, the zipper teeth can be meshed, when the fabric is pulled, the rubber strip 6 is arranged at the foremost end and the fabric can be firstly contacted with the rubber strip 6, the fabric can be clamped by the rubber strip 6 due to the large friction force, and can be timely discovered by a user, and the situation that the fabric is completely clamped in the zipper head is prevented, the disease is prevented in the bud.

In this embodiment, the surface of the rubber strip 6 is provided with the bumps 9, and from a physicochemical point of view, the weaker the crosslinking, the higher the wear rate, since a lower degree of crosslinking is easily broken by mechanical stress. It was found that electron beam irradiation leads to an increase in the degree of crosslinking of the ethylene-propylene-diene rubber, so that the friction is reduced. The level of the rubber surface free energy determines the magnitude of the interaction force between the rubber and the couple, and further influences the adhesive friction of the rubber. Generally, the friction coefficient increases with the increase of the surface free energy, and the provision of the protrusions 9 on the surface of the rubber strip 6 increases the free energy of the rubber strip 6, thereby enhancing the adhesive ability of the rubber and increasing the friction force.

The utility model has the advantages that: the utility model provides a zipper puller for preventing fabric from being clamped in, which acts on zipper teeth and comprises a zipper upper lock plate, a zipper lower lock plate and a zipper pull piece, wherein the zipper pull piece is arranged on the upper lock plate, the zipper upper lock plate is connected with the zipper lower lock plate through a zipper tooth, and the front end of the zipper upper lock plate is provided with a rubber strip for increasing the friction force between the fabric and the zipper upper lock plate; the front end through the jam plate on the zip fastener sets up the rubber strip for the front edge of jam plate on the zip fastener is closely laminated to the rubber strip, thereby has increased the friction dynamics of drawing zipper head and cloth, will lead to the zip fastener to block when making the front end department of drawing zipper head and cloth touching, thereby makes the user in time discover, puts aside the cloth, prevents that the cloth from all being drawn into and drawing zipper head inside and blocking the zip fastener, prevents to suffer from in the bud, has improved the life of zip fastener and cloth greatly, and the practicality is extremely wide.

The above disclosure is only for the specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be made by those skilled in the art should fall within the protection scope of the present invention.
