Description

Stable and strong-pulling-force-resistant zipper

Technical Field

The invention belongs to the technical field of zippers, and particularly relates to a zipper capable of stably resisting strong pulling force.

Background

The zipper structure on the market at present is that the left and right identical zipper teeth are forced to be squeezed into the left and right vacant positions through the pressing heads to form a whole, the whole structure is unstable, the method and the habitual defects are caused, so that a plurality of zippers can not be closed after a period of time, if a certain tooth position is distorted, or abraded and the like, even if some zipper teeth of a new zipper are made of metal such as copper, aluminum or even iron, the zipper teeth can not be closed completely, but the zipper teeth can not be closed completely due to the fact that the placing time is one or two years, the zipper teeth can be contacted with a wardrobe normally at home, the surfaces of the zipper teeth cannot be closed completely, so that a plurality of metal zippers can be damaged after a long time, the zipper teeth can not be closed easily due to the fact that the pressure resistance is not strong, therefore, the zipper cannot be applied to the combined strong fabric or the pulling tool, and only the zipper can be bound by buttons, ropes and the like, so that the zipper is not good in convenience and folding, and the use scene is limited.

Disclosure of Invention

In order to facilitate life and serve people to better use the zipper in various occasions, the invention provides the stable and strong-pulling-force-resistant zipper, and the method and the manufactured product thereof can better solve the technical defects of the zipper in the background technology. The beneficial effects are that: the structure is simple, the production cost is low, the zipper can be widely applied, the stable structure is stronger, the zipper can not be cracked and separated particularly under the condition of bearing stronger pulling force, the stable clamping box body and the stable clamping plug are not cracked unless the stable clamping box body and the stable clamping plug are cracked by the pulling force, but the cracking of the zipper with high density and uniform stress is not easy, because the zipper is inserted and clamped, if the stable clamping box body and the stable clamping plug which are made of metal are used (the bearing force is larger unless dense metal is cracked), the zipper can be durable, the use cannot be influenced due to long placing time or surface abrasion of the zipper, the whole zipper and the method of the zipper are different from that of a common zipper, but the zipper is convenient to use.

The invention is characterized in that: the novel zipper comprises a socket, a plug, a pressing head pulled up and down, a pulling piece, salient points inside the pressing head, connecting points of an upper cover plate and a lower cover plate of the pressing head and the like, wherein the fabric piece is connected with a stable clamping box body on the left side of a zipper and a stable clamping plug on the right side of the zipper through a fabric line to form a chain edge combined clamping line and can be pulled up and down through the pressing head, the stable clamping box body is provided with a stable clamping box body insertion hole and a warping strip groove, the warping strip is placed in the warping strip groove, the stable clamping box body is fixedly positioned by two warping strip movable central columns, an upper warping strip and a lower warping strip are arranged between the inner ends of the two warping strips, a spring is arranged between the inner ends of the two warping strips to elastically press, a warping strip pressing point at the left end of the warping strip keeps outwards elastically pressed, meanwhile, a warping strip clamping point is elastically pressed inwards stressed, the salient points inside the pressing head upper cover plate and the.

When the inner convex point of the pressing head presses the buckling strip pressing point, the buckling strip pressing point at the right end of the buckling strip is outwards pressed, and the card stabilizing plug can completely pass through the card stabilizing box body.

Detailed Description

The present invention will be further described with reference to the accompanying drawings, 1-7, wherein only a few embodiments of the present invention are shown and described, and various changes, equivalents and modifications can be made therein by those skilled in the art without departing from the scope of the present invention as defined in the appended claims.

Referring to fig. 1, a socket U and a plunger U1 are both used as a common zipper, a vertically-pulled press-fit head 5 has a pulling piece 6, the internal structure of the press-fit head 5 is as shown in fig. 2 as an upper cover plate 5A of the press-fit head, fig. 3 as a lower cover plate 5B of the press-fit head, fig. 2 and fig. 3 both have a corresponding inner salient point X of the press-fit head and a connecting point Y of the upper and lower cover plates of the press-fit head 5, a fabric piece is connected with a left stable box body 1 and a right stable plug 2 of the zipper through a fabric line to form a left combined clamping line 3 and a right combined clamping line 4 of a chain edge, which are vertically pulled by the press-fit head 5, as shown in fig. 4, a three-dimensional stable box body insertion port 9 is seen, the stable box body 1 has a set warping strip groove 12, the warping strip 7 is placed in the warping strip groove 12, the stable box body 1 is fixed and positioned by two warping movable central posts 8, the upper and lower warping strips 7, therefore, the warping strip pressing point 10 at the left end of the warping strip 7 keeps outwards bouncing, meanwhile, the warping strip clamping point 11 is inwards stressed and bounced, and the warping strip pressing point 10 of the warping strip 7 is pressed when the upper pressing head cover plate 5A and the lower pressing head cover plate 5B of the pressing head 5 are internally provided with the vertically corresponding protruding points X in the pressing head and pulled.

When the inner salient point X of the pressing head 5 is pressed to the upper and lower warped strip pressing points 10, the warped strip clamping point 11 at the right end of the warped strip 7 is outwards pressed (as shown in fig. 7), and the card-stabilizing plug 2 can completely pass through the card-stabilizing box body 1, so that when the pressing head 5 is pulled up and down, the upper and lower cover plate connecting points Y can separate the chains at the left and right sides or upwards press the chains, and when the chains are pressed, the inner salient point X of the pressing head is passed through due to upward pulling, so that the warped strip pressing point 10 of the warped strip 7 is outwards opened, the warped strip clamping point 11 is inwards pressed, and the card-stabilizing plug 2 is pressed in the card-stabilizing box body 1 by the pressing head 5. The card stabilizing plug 2 can be made of plastic or metal when being inserted into the card stabilizing box body 1, the structures of the card stabilizing plug are matched with each other, the card stabilizing plug can be firmly and stably matched together, if the hardness of the fabric piece is high, the whole fabric piece can form a plane platform for placing or supporting other articles, and more fabric pieces can be used on clothes and box bodies.
