Furthermore, the terms "first," "second," "third," "fourth," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In order to better understand the aspects of the present application, a further detailed description of the present application will be provided below with reference to the accompanying drawings and detailed description.

As shown in fig. 2, in the present embodiment, a rear group slider is provided, which includes a slider body 1, a tab 3, and a connecting piece 2 connecting the two. The pull body 1 is an existing general piece, can be made of different materials and different types of zipper heads, and can be matched with the zipper teeth.

Referring to fig. 3, the connecting piece 2 includes a rear connecting portion for connecting the pull body 1 and a front connecting portion for connecting the tab 3, and the specific connection manner of the rear connecting portion and the pull body 1 is not described in detail herein, and specific reference may be made to the prior art. Of course, the front connecting part and the rear connecting part are of an integrated structure or a fixed connecting structure, and have higher stability.

The front connection part includes an upper cover plate 21 having an upper hole 23 and a lower cover plate 22 having a lower hole 24, and the lower cover plate 22 is spaced apart from the upper cover plate 21. Referring to fig. 4 and 5, the lower cover 22 extends toward the lower hole 24 and protrudes from the upper cover 21, so that when the tab 3 enters the connector 2 through the upper hole 23, the end of the tab contacts the wall of the upper hole 23 of the lower cover 22.

That is, since the lower cover 22 is disposed to protrude from the upper cover 21, no matter the tab 3 is in the entering mode as shown in fig. 6 or in the entering mode as shown in fig. 7, it is first contacted with the wall surface of the lower cover 22, but not contacted with the side angle of the lower cover 22, so that the influence of the side angle of the lower cover 22 on the tab 3 is avoided.

It should be noted that, if the entering manner shown in fig. 6 is adopted, that is, the tab 3 is obliquely inserted into the connecting piece 2, during the assembling process, since the lower cover plate 22 is protruded from the upper cover plate 21, a width difference is formed, so that the tab 3 is blocked by the protruding portion of the lower cover plate 22 during the inserting, and is more easily distorted and deformed under the slightly downward inserting force, so that the tab 3 slides towards the interval direction between the lower cover plate 22 and the upper cover plate 21, and is not easily penetrated out from the lower hole 24, thereby improving the assembling efficiency.

If the entry manner shown in fig. 7 is adopted, even if the tab 3 does not have an inclination angle when penetrating the connecting member 2, the convex portion of the lower cover plate 22 can completely block the tab 3, and a slight change of the direction of the force can deform the tab 3 to change the sliding direction so as to enter the interval between the upper cover plate 21 and the lower cover plate 22.

In summary, the connecting piece 2 of the rear group slider of the present application includes the upper cover plate 21 and the lower cover plate 22 having the width difference, and the tab 3 comes into contact with the protruding portion of the lower cover plate 22, i.e., the portion having the width difference, when it enters the connecting piece 2 through the upper hole 23. Therefore, the tab 3 cannot touch the side angle of the lower cover plate 22 in the entering process, and can slide into the interval between the upper cover plate 21 and the lower cover plate 22 more easily, so that the assembly efficiency is improved. On the basis, the assembly efficiency can be ensured without increasing the interval distance, and meanwhile, the interval distance can be reduced, and the thickness of the tab 3 is reduced, so that the tab 3 and the connecting piece 2 have stronger bonding force. Therefore, the rear group of sliders arranged in the mode has the advantages of strong binding force and high assembly efficiency.

In addition, as can be seen in fig. 4, the front projection of the lower cover plate 22 in the direction of the upper cover plate 21, one part falls on the upper cover plate 21, the other part falls on the upper hole 23, and the part corresponding to the front projection falling on the upper hole 23 is the protruding part of the lower cover plate 22. In addition, only the protruding portion of one side of the lower cover 22 is shown in fig. 4, and the two sides of the lower cover 22 may also extend toward the lower hole 24, so that the tab 3 cannot pass through the lower hole 24, thereby further ensuring the assembly efficiency of the slider.

In order to further improve the efficiency of the tab 3 entering the space between the upper cover 21 and the lower cover 22, in this embodiment, the wall surface of the lower cover 22 facing the upper hole 23 is a cambered surface or inclined surface with a high inner side and a low outer side, where the inner side refers to the side close to the upper hole 23 and the outer side refers to the side far from the upper hole 23. When the tab 3 enters the connecting piece 2, the end part of the tab 3 can be contacted with the cambered surface or the inclined surface, so that the direction of the end part of the tab 3 is changed, and when the tab 3 moves towards the interval between the upper cover plate 21 and the lower cover plate 22, the tab 3 can be automatically commutated without manual inclination, and the assembly efficiency is higher.

In addition, in order to make the passage of the tab 3 in the space between the upper cover plate 21 and the lower cover plate 22 smoother, the thickness of the tab 3 may be slightly smaller than or equal to the spacing of the space. The tab 3 can be made of a material that deforms elastically, and can maintain tightness with the connecting piece 2 while not affecting access to the connecting piece 2.

It should be noted that, since the tab 3 has a certain thickness, a certain limitation needs to be made on the protruding width of the lower cover plate 22, and on this basis, the thickness of the tab 3 may be slightly smaller than or equal to the interval, and on this basis, the orthographic projection width of the upper cover plate 21 falling onto the upper hole 23, that is, the protruding width of the lower cover plate 22, is greater than the thickness of the tab 3, so as to ensure that at least half of the tab 3 falls onto the protruding portion of the lower cover plate 22, and thus avoid the tab 3 falling out from the lower hole 24. For the maximum width of the protruding portion, the thickness of the protruding portion may be smaller than the thickness of the tab 3 or larger than the thickness of the tab 3, but it is necessary to ensure that the lower hole 24 has a certain open area, so that the positioning portion 31 can perform a limit clamping connection through the upper hole 23 and the lower hole 24.

As can be seen in fig. 3 and the prior art, the connecting piece 2 further comprises two side plates connecting the upper cover plate 21 and the lower cover plate 22, wherein the lower cover plate 22 is communicated with the space between the upper cover plate 21, the upper hole 23 and the lower hole 24, and forms an inner cavity of the connecting piece 2. In the process of penetrating through the connecting piece 2, one end with the positioning part 31 is embedded into the inner cavity of the connecting piece 2, and is in limit clamping connection with the upper hole 23 and the lower hole 24 through the positioning part 31, so that the positioning performance of the positioning part 31 is further enhanced. If the inclined surface or the cambered surface is avoided, the inclined surface or the cambered surface matched with the wall surface is also required to be arranged on the positioning part 31, so that the positioning part 31 is perfectly matched with the inner cavity.

Further, since the lower cover plate 22 extends in the direction of the lower hole 24, the area of the lower hole 24 is smaller than that of the upper hole 23, and the area of the positioning portion 31 facing the side of the lower hole 24 is smaller. In the process of entering the inner cavity, the side of the positioning portion 31 facing the lower hole 24 enters the inner cavity first, so that the positioning portion 31 is easier to enter the inner cavity.

Because the tab 3 of the rear group of sliders generally adopts elastic deformation materials, in order to make the connection between the positioning portion 31 and the inner cavity of the connecting piece 2 more stable, the positioning portion 31 is in interference fit with the inner cavity, and the connection stability of the positioning portion 31 and the inner cavity is improved by a certain compression amount of the positioning portion 31.

In addition, compared with the existing connecting piece 2, the connecting piece 2 with the structure does not need to better penetrate the tab 3 due to the fact that the distance between the upper cover plate 21 and the lower cover plate 22 is increased, so that the thickness of the connecting piece 2 is thinner, the combination of the tab 3 and the connecting piece 2 is tighter and firmer, and the combined rear group of sliders is shown in fig. 8.

It should be noted that, the lower cover 22 and the upper cover 21 are only relatively speaking, and the case that the upper cover 21 has a protruding portion with respect to the lower cover 22 is also an embodiment of the present utility model, which is not described in detail herein, and falls within the protection scope of the present application.

In addition, the application also provides a zipper comprising the rear group of sliders, and the rear group of sliders and the fittings such as the zipper teeth are matched to form the zipper. Because the rear group slider of the zipper has the advantage of high assembly efficiency, the production efficiency of the zipper can be greatly improved. Simultaneously, the application still provides a dress including above-mentioned zip fastener, and the same production efficiency that also can improve the dress. It should be noted that the above-mentioned slide fastener is not limited to clothing applications, but can be applied to articles requiring slide fasteners such as bags, shoes, and the like.

It should be noted that in this specification relational terms such as first and second are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.

Specific examples are set forth herein to illustrate the principles and embodiments of the present application, and the description of the examples above is only intended to assist in understanding the methods of the present application and their core ideas. It should be noted that it would be obvious to those skilled in the art that various improvements and modifications can be made to the present application without departing from the principles of the present application, and such improvements and modifications fall within the scope of the claims of the present application.
