Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and particularly relates to a zipper. Background Art

[0002] For commonly used home textile clothes such as down jackets, duvet covers, pajamas, etc., most of the inner fabrics will come into contact with the human skin. To achieve a comfortable body feeling, the inner fabrics are made very soft. When the zipper is opened or closed, the soft and thin inner fabric is likely to get stuck in the seam of the slider, resulting in problems such as jamming during pulling.

[0003] The existing technology mainly uses a cloth tape with a special shape. The cloth tape includes a first flanging and a second flanging, and the first flanging and the second flanging block both sides of the slider to isolate the clothing fabric from the sliding slider, thereby achieving the anti-catching effect of the zipper on the fabric. However, the disadvantage of the existing technology is that both the first flanging and the second flanging of the cloth tape are made of soft fabric, and the angles and shapes of the flangings are difficult to remain unchanged like in the theoretical state. It is very difficult to effectively cover the seam of the slider, and it can only play a role in preventing the cloth edge from being caught to a certain extent, and cannot completely avoid the cloth edge from being caught. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a zipper. The bent parts added to the two chain teeth respectively abut against both sides of the lower wing plate of the slider, preventing the flexible fabric from entering between the two chain teeth, and solving the technical problem of poor anti-catching effect of the existing zipper on the cloth edge.

[0005] To achieve the above purpose, the utility model provides a zipper, including:

[0006] A first chain tooth and a second chain tooth which are oppositely arranged;

[0007] A slider for locking or separating the first chain tooth and the second chain tooth;

[0008] The slider includes a lower wing plate. On the sides of the first chain tooth and the second chain tooth facing the lower wing plate, a first bent part and a second bent part are respectively formed by bending; when the first chain tooth and the second chain tooth are locked, the first bent part and the second bent part respectively abut against both sides of the lower wing plate.

[0010] Preferably, the first lower clamping part includes two first lower abutting rods arranged in parallel, and the first bending part is a U-shaped structure integrally and vertically connected between the two first lower abutting rods; the second chain tooth includes two second lower abutting rods arranged in parallel and coplanar with the first lower abutting rods, and the second bending part is a U-shaped structure integrally and vertically connected between the two second lower abutting rods.

[0011] Preferably, the heights of both the first bending part and the second bending part are greater than or equal to the thickness of the lower wing plate.

[0012] Preferably, the slider includes an upper wing plate opposite to the lower wing plate; the first chain tooth further includes a first upper clamping part for abutting between the first fabric belt and the upper wing plate. The first lower clamping part is parallel to the first upper clamping part, and a first cloth clamping groove for clamping the first fabric belt is formed between the first lower clamping part and the first upper clamping part; the second chain tooth further includes a second upper clamping part for abutting between the second fabric belt and the upper wing plate. The second lower clamping part is parallel to the second upper clamping part, and a second cloth clamping groove for clamping the second fabric belt is formed between the second lower clamping part and the second upper clamping part.

[0013] Preferably, the first chain tooth further includes a first connecting part for integrally bending and connecting the first upper clamping part and the first lower clamping part; the second chain tooth further includes a second connecting part for integrally bending and connecting the second upper clamping part and the second lower clamping part.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] The utility model embodiment discloses a zipper, as shown in the attached Figure 1 and 2 As shown, it includes first chain teeth 1, second chain teeth 2 and a pull head 3, a plurality of first chain teeth 1 are evenly arranged along one side of the first fabric tape 4, a plurality of second chain teeth 2 are evenly arranged along the first side of the second fabric tape 5, and the first chain teeth 1 and the second chain teeth 2 are arranged opposite to each other. However, it should be supplemented that all the first chain teeth 1 and all the second chain teeth 2 are arranged alternately, that is, one of the second chain teeth 2 is aligned with the first clamping groove formed by the two adjacent first chain teeth 1, so that the two adjacent first chain teeth 1 can be squeezed by the pull head 3 by clamping one of the second chain teeth 2, so that the first chain teeth 1 and the second chain teeth 2 are locked, thereby connecting the first fabric tape 4 and the second fabric tape 5.

[0036] The pull head 3 is used to lock or separate the first chain element 1 and the second chain element 2, thereby connecting or separating the first cloth tape 4 and the second cloth tape 5. Figure 2 As shown, the slider 3 includes a lower wing plate 31, an upper wing plate 32, a cap 33 and a pull tab 34. The cap 33 is fixed on the upper wing plate 32, and the pull tab 34 is installed on the cap 33. The upper wing plate 32 and the lower wing plate 31 are parallel to each other, and the lower wing plate 31 and the lower wing plate 31 are fixedly connected by a guide column. When the pull tab 34 is lifted, the guide column guides the first chain tooth 1 and the second chain tooth 2 to move closer to each other. Under the joint extrusion of the upper wing plate 32 and the lower wing plate 31, the first chain tooth 1 and the second chain tooth 2 are engaged, and the two chain teeth are locked. When the pull tab 34 is pulled down, the upper wing plate 32 and the lower wing plate 31 contact and constrain the two chain teeth, and the first chain tooth 1 and the second chain tooth 2 are separated from each other under the guidance of the guide column, and the two chain teeth are separated.

[0037] As attached Figure 1 As shown, the first chain tooth 1 and the second chain tooth 2 are bent toward one side of the lower wing plate 31 to form a first bending portion 11 and a second bending portion 21 respectively; when the slider 3 locks the first chain tooth 1 and the second chain tooth 2, the first bending portion 11 and the second bending portion 21 are respectively abutted against the two sides of the lower wing plate 31 to prevent the flexible fabric from entering between the two chain teeth, thereby playing a good role in preventing the cloth edge from getting stuck.

[0038] In the first specific embodiment, as shown in the appended Figure 1 and 3 figures, the first chain tooth 1 includes a first lower clamping portion 12, and the first lower clamping portion 12 is used to abut between the first fabric strip 4 and the lower wing plate 31. The first lower clamping portion 12 is integrally and perpendicularly connected to the first bending portion 11, so that the first bending portion 11 can abut against the lower wing plate 31 and fully separate the flexible fabric of the lower wing plate 31 and the sagging first fabric strip 4, ensuring that the anti-fabric jamming effect of the first bending portion 11 reaches the best. Similarly, as shown in the appended Figure 6 figures, the second chain tooth 2 includes a second lower clamping portion 22, and the second lower clamping portion 22 is used to abut between the second fabric strip 5 and the lower wing plate 31. The second lower clamping portion 22 is integrally and perpendicularly connected to the second bending portion 21, so that the second bending portion 21 fully separates the flexible fabric of the lower wing plate 31 and the sagging second fabric strip 5, ensuring that the anti-fabric jamming effect of the second bending portion 21 reaches the best.

[0039] As shown in the appended Figure 1 and 4 figures, in the first specific embodiment, the first lower clamping portion 12 includes two first lower abutting rods arranged in parallel. The first bending portion 11 is a U-shaped structure integrally and perpendicularly connected between the two first lower abutting rods, which improves the mechanical strength of the first bending portion 11 and prevents the first bending portion 11 from being bent and deformed under the extrusion of the lower wing plate 31, thus affecting its anti-fabric jamming effect. Similarly, the second chain tooth 2 includes two second lower abutting rods arranged in parallel and coplanar with the first lower abutting rods. The second bending portion 21 is a U-shaped structure integrally and perpendicularly connected between the two second lower abutting rods, which improves the mechanical strength of the second bending portion 21 and prevents the second bending portion 21 from being bent and deformed under the extrusion of the lower wing plate 31, thus affecting its anti-fabric jamming effect.

[0040] In the first specific embodiment, the heights of both the first bending portion 11 and the second bending portion 21 are greater than or equal to the thickness of the lower wing plate 31, so that the first bending portion 11 fully separates the flexible fabric of the lower wing plate 31 and the sagging first fabric strip 4, and the second bending portion 21 fully separates the flexible fabric of the lower wing plate 31 and the sagging second fabric strip 5, improving the anti-fabric jamming effect.

[0041] As shown in the appended Figure 2 、 4As shown in FIGS. 4 and 5, the first chain tooth 1 further includes a first upper clamping portion 13 which abuts between the first cloth tape 4 and the upper wing plate 32. The first lower clamping portion 12 is parallel to the first upper clamping portion 13. A first cloth clamping groove 14 for clamping the first cloth tape 4 is formed between the first lower clamping portion 12 and the first upper clamping portion 13, so that the first chain tooth 1 is reliably fixed to the edge of the first cloth tape 4. The second chain tooth 2 further includes a second upper clamping portion 23 which is used to abut between the second cloth tape 5 and the upper wing plate 32. The second lower clamping portion 22 is parallel to the second upper clamping portion 23. A second cloth clamping groove 24 for clamping the second cloth tape 5 is formed between the second lower clamping portion 22 and the second upper clamping portion 23, so that the second chain tooth 2 is reliably fixed to the edge of the second cloth tape 5.

[0042] As shown in the Figures 4 to 6 accompanying drawings, the first chain tooth 1 further includes a first connecting portion 15 for integrally bending and connecting the first upper clamping portion 13 and the first lower clamping portion 12. The second chain tooth 2 further includes a second connecting portion 25 for integrally bending and connecting the second upper clamping portion 23 and the second lower clamping portion 22. Both the first connecting portion 15 and the second connecting portion 25 are U-shaped structures. Thus, both the first cloth clamping groove 14 and the second cloth clamping groove 24 are U-shaped grooves. During the movement of the slider 3, the opposite sides of the first connecting portion 15 and the second connecting portion 25 are respectively opposite to both sides of the guiding post. The U-shaped structure can reduce the contact area with the guiding post to a certain extent, thereby reducing the frictional force between the first connecting portion 15 and the guiding post and between the second connecting portion 25 and the guiding post, avoiding wear and breakage of both the first connecting portion 15 and the second connecting portion 25, and being beneficial to extending the service life of both the first chain tooth 1 and the second chain tooth 2.

[0043] The length of the first lower clamping portion 12 is greater than that of the first upper clamping portion 13; the length of the second lower clamping portion 22 is greater than that of the second upper clamping portion 23, providing conditions for the setting of the first bending portion 11 by the first lower clamping portion 12 and providing conditions for the setting of the second bending portion 21 by the second lower clamping portion 22, avoiding interference between the first bending portion 11 and the lower wing plate 31 due to the too short length of the first lower clamping portion 12, and avoiding interference between the second bending portion 21 and the lower wing plate 31 due to the too short length of the second lower clamping portion 22.

[0044] The first upper clamping portion 13 is a U-shaped structure, which improves the mechanical strength of the first upper clamping portion 13 and increases the contact area between the first chain tooth 1 and the first cloth tape 4 to ensure that the first chain tooth 1 clamps the first cloth tape 4. The second upper clamping portion 23 is a U-shaped structure, which improves the mechanical strength of the second upper clamping portion 23 and increases the contact area between the second chain tooth 2 and the second cloth tape 5 to ensure that the second chain tooth 2 clamps the second cloth tape 5.

[0045] Both the first upper clamping part 13 and the second upper clamping part 23 are respectively abutted against both sides of the locking groove 321 provided on the upper wing plate 32. When the zipper is lifted, the first chain teeth 1 and the second chain teeth 2 are mutually engaged under the extrusion of the locking groove 321 to achieve locking. The thicknesses of both the first upper clamping part 13 and the second upper clamping part 23 are equal to the depth of the locking groove 321.

[0046] Compared with the first specific embodiment, the second specific embodiment lies in further optimizing the structures of the first chain teeth 1 and the second chain teeth 2. In the second specific embodiment, as shown in the appendix Figure 7 As shown, the first chain teeth 1 further include a first extension part 16. The first lower clamping part 12 and the first extension part 16 are integrally bent and connected through a first bending part 11, and they are respectively abutted against the upper and lower sides of the lower wing plate 31, so that the first clamping part, the first bending part 11 and the first extension part 16 are connected in sequence to form a first engaging part. The first engaging part is of a U-shaped structure, and the first engaging part is in clamping fit with the first side of the lower wing plate 31, which can not only fully separate the first cloth tape 4 and the lower wing plate 31, but also enhance the connection strength between the first chain teeth 1 and the pull head 3. Similarly, the second chain teeth 2 further include a second extension part 26. The second lower clamping part 22 and the second extension part 26 are integrally bent and connected through a second bending part 21, and they are respectively abutted against the upper and lower sides of the lower wing plate 31, so that the second clamping part, the second bending part 21 and the second extension part 26 are connected in sequence to form a second engaging part. The second engaging part is of a U-shaped structure, and the second engaging part is in clamping fit with the second side of the lower wing plate 31, which can not only fully separate the second cloth tape 5 and the lower wing plate 31, but also enhance the connection strength between the second chain teeth 2 and the pull head 3.

[0047] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
