Description

Technical Field

[0001] The utility model relates to the technical field of zippers, and more specifically, to a convenient zipper. Background Art

[0002] Zippers are a common accessory in clothing and bags, and are connectors that enable the openings of clothing and bags to be closed and opened.

[0003] The utility model Chinese patent with announcement number CN221012219U introduces a zipper, a slider and a replaceable pull-tab structure, wherein the replaceable pull-tab structure comprises: a pull-tab connecting portion, one end of which is riveted to the slider body, the horse hook and the cap; an adapter base, which is arranged at the other end of the pull-tab connecting portion; a replaceable pull-tab, which is sleeved outside the mounting seat of the adapter base; a cover plate, which is detachably connected to the mounting seat; an elastic baffle, which is arranged between the mounting seat and the cover plate, and comprises an elastic button portion and at least one baffle arranged on the outer edge of the elastic button portion, the elastic button portion protrudes from the through hole of the cover plate, and the baffle protrudes from the outer peripheral surface of the mounting seat, and the baffle is used to limit the displacement of the replaceable pull-tab in the height direction.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.

[0022] like Figure 1 and Figure 2As shown, the present application provides a convenient zipper, including a chain tooth 1, a chain head 2 and a pull tab 3, wherein a plurality of chain teeth 1 are provided, and the plurality of chain teeth 1 are fixed on a cloth strip at intervals, and the pull tab 3 is installed on the chain head 2, and the chain head 2 can slide on the chain tooth 1 by pulling the pull tab 3, wherein the chain head 2 includes a base and two pressure blocks 4, and the two pressure blocks 4 are both installed on the base, and a connecting space is formed between the two pressure blocks 4 and the base, and a portion of the pull tab 3 passes through the connecting space, and the abutment of the pressure blocks 4 is utilized to keep the old piece and the chain head 2 connected.

[0023] like Figure 2 and Figure 3 as well as Figure 4 As shown, a movable opening is formed between the two pressing blocks 4, and the connecting space is connected with the outside through the movable opening, wherein a shielding member is movably arranged in the movable opening, and the shielding member will shield the movable opening, so that part of the pull tab 3 always remains in the connecting space, ensuring the connection between the pull tab 3 and the chain head 2.

[0024] like Figure 2 and Figure 3 as well as Figure 4 As shown, the shielding member includes a rotating column 5, which is rotatably arranged between two pressing blocks 4. The rotating column 5 is formed with a clearance opening 6. The operator can rotate the rotating column 5 to make the clearance opening 6 correspond to the connection space or the outside world, and the edge of the clearance opening 6 is formed with a guiding arc surface, which can guide the operation of the pull tab 3 sliding into the clearance opening 6, thereby increasing convenience.

[0025] When the pull tab 3 is damaged and deformed, rotate the rotating column 5 so that the clearance port 6 corresponds to the connection space. Then pull the pull tab 3 so that the pull tab 3 slides into the clearance port 6. Rotate the rotating column 5 again so that the clearance port 6 is misaligned with the connection space and the clearance port 6 corresponds to the outside world. At this time, the pull tab 3 slides out of the clearance port 6 so that the pull tab 3 will not pass through the connection space. At this time, the separation of the pull tab 3 and the chain head 2 is completed, and the disassembly of the pull tab 3 is completed.

[0026] After taking the new pull tab 3, make sure that the clearance opening 6 corresponds to the outside world, slide the pull tab 3 into the clearance opening 6, then rotate the rotating column 5 to make the clearance opening 6 misaligned with the outside world, and make the clearance opening 6 correspond to the connecting space, so that the pull tab 3 slides into the connecting space. At this time, the connection between the pull tab 3 and the chain head 2 is completed. In this way, the pull tab 3 can be replaced without using tools, so that after the pull tab 3 is deformed and damaged, the zipper can continue to be used by replacing the pull tab 3.

[0027] like Figure 2 and Figure 3 as well as Figure 4As shown, an arc-shaped spring piece 7 is fixedly installed in the clearance opening 6. When the pull tab 3 enters the clearance opening 6, pressure needs to be applied to the arc-shaped spring piece 7 so that the arc-shaped spring piece 7 is deformed by the force, so that the pull tab 3 can enter the clearance opening 6. This can reduce the possibility of the pull tab 3 accidentally making the clearance opening 6 during normal use of the zipper, thereby ensuring the connection stability between the pull tab 3 and the chain head 2. The rotating column 5 is formed with anti-slip grooves 8, which can increase the friction between the hand and the rotating column 5, thereby facilitating the rotation of the rotating column 5. The two pressing blocks 4 are fixedly connected with friction pads 9 at positions close to each other. The rotating column 5 is formed with friction grooves 10 that contact the friction pads 9. The contact between the friction pads 9 and the friction grooves 10 can increase the force required for the sliding of the rotating column 5, reduce the probability of the rotating column 5 accidentally rotating, and make the clearance opening 6 correspond to the connection space, further ensuring the connection stability between the pull tab 3 and the chain head 2.

[0028] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
