Technical Field

[0001] The utility model relates to the technical field of zipper design, in particular to a double-head zipper. Background Art

[0002] A double-ended zipper is a zipper with two sliders that allows it to be opened and closed from two directions. This design makes the double-ended zipper more flexible and can be operated at both ends at the same time, providing more convenience and usage options. Double-ended zippers are usually used for items that need to be easily opened and closed from two directions. However, in the prior art, when the zipper on thick plush fabric is slid up and down, plush is easily stuck in the zipper, causing the zipper to be unable to slide, and excessive force may even cause the zipper to be damaged. Utility Model Content

[0003] The utility model aims to solve the defect in the prior art that the plush is stuck in the zipper, causing the zipper to be unable to slide, and provides a double-head zipper.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a double-head zipper, comprising a cloth tape, one end of the cloth tape is fixedly connected to a chain tooth, the bottom of the chain tooth is fixedly connected to a fixed stop, the top of the chain tooth is fixedly connected to an upper stop, the bottom of the cloth tape is fixedly connected to a cloth adhesive, the surface of the cloth adhesive is provided with an upper clamping seat, the surface of the upper clamping seat is fixedly connected to a chain buckle block, the bottom of the upper clamping seat is fixedly connected to a locking upper groove block, the bottom end of the upper clamping seat is fixedly connected to a locking head, the bottom end of the locking head is fixedly connected to a lower clamping seat, the surface of the lower clamping seat is fixedly connected to a locking lower groove block, and arc-pulling plates are fixedly connected to both sides of the lower clamping seat.

[0005] As a preferred embodiment, both inner ends of the cloth belt are fixedly connected with chain teeth, and the chain teeth on both sides are staggered and connected.

[0006] The technical effect of adopting the above further solution is: the two chain teeth are fixedly connected to the inner ends of the cloth tape in an opposite and staggered manner, so that the chain teeth on both sides are staggered and closely fitted when the zipper is pulled upward.

[0007] As a preferred implementation, the lengths of both ends of the arc-stirring plate exceed the upper and lower ends of the lower holder.

[0008] The technical effect of adopting the above further solution is: for thicker plush fabrics, when the lower holder is pulled up or down, the two ends of the arc plate will push the plush covering the chain teeth outward to prevent the lower holder from getting stuck when moving up and down.

[0009] As a preferred embodiment, there are two locking upper slot blocks and two locking lower slot blocks, which are respectively fixedly connected to the two sides of the bottom of the upper card seat and the two sides of the surface of the lower card seat, and the locking upper slot blocks and the locking lower slot blocks are respectively fixed oppositely on the surfaces of the upper card seat and the lower card seat.

[0010] As a preferred implementation, the rear ends of the upper clamping seat and the lower clamping seat are fixedly connected with magnetic blocks.

[0011] The technical effect of adopting the above further solution is that the magnetic block is magnetic and is magnetically attracted to the magnetic block set at the tail of the zipper at the other end, preventing the upper zipper from sliding freely when the double-head zipper only contacts the chain teeth on one side.

[0012] As a preferred embodiment, one end of the locking lower slot block is provided with a downward slope surface.

[0013] The technical effect of adopting the above further solution is: it is easy to slide the chain teeth along the lower end of the locking lower groove block, making the opening and closing of the zipper smoother and enhancing the user's experience.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] In the utility model, an arc-pushing plate is designed and thickened plush fabric is used around the chain teeth. Both ends of the arc-pushing plate extend beyond the upper and lower ends of the lower clamping seat, so the plush around the chain teeth can be pushed to the outside to prevent the plush from being stuck in the slot between the upper clamping seat and the lower clamping seat when the zipper of the lower clamping seat moves up and down, thereby increasing the customer's user experience.
