Elephant-trunk slider applied to invisible zipper

Abstract

An elephant-trunk slider applied to an invisible zipper, the elephant-trunk slider comprising a base plate (1), wherein a base core post (2) is provided on the top of the base plate (1). During assembly, a limiting post (7) is lifted into a storage slot (6), then a pull tab is assembled in the interior of an elephant-trunk fastener (4), and the elephant-trunk fastener (4) is then pressed to bend. At this point, the limiting post (7) is inserted into a positioning slot (5) to block the pull tab. The bending of the elephant-trunk fastener (4) further reduces the up-down movement distance of the limiting post (7). Therefore, even if a gap appears between the limiting post (7) and a separation plate (3) at a later stage, the gap is far smaller than the thickness of the pull tab. Therefore, while ensuring that the pull tab does not detach after assembly, the bending degree of the elephant-trunk fastener (4) is further reduced, thereby reducing the deformation amount thereof, and preventing a plating layer thereon from detaching.

Description

An elephant trunk zipper pull for use with invisible zippers Technical Field

[0001] This utility model relates to the field of zipper pull technology, specifically to an elephant trunk zipper pull for use in concealed zippers. Background Technology

[0002] The elephant trunk zipper pull is a type of zipper pull mainly used on zippers in bags, tents, and other items that do not require a locking function. It is called an elephant trunk zipper pull because its overall structure resembles an elephant's trunk. Due to its unique design and sturdy and durable characteristics, it has become one of the most commonly used zipper pull types.

[0003] Most existing N466 concealed zipper pulls use two clamping plates to hold and limit the pull tab. When assembling the pull tab, they are often assembled using a crab-clamp method. This assembly method makes it easy for the plating on the clamping plates to peel off when the clamping plates are squeezed. To avoid plating peeling off, the N466 concealed zipper pull can only be electroplated and cannot be painted. The processing method is relatively simple. In addition, the N466 concealed zipper pull has an integrated flat upper plate, which consumes more raw materials and has a higher production cost during mass production.

[0004] Utility Model Content

[0005] The purpose of this invention is to provide an elephant trunk zipper pull for use in invisible zippers, in order to solve the technical problems mentioned in the background section.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] An elephant trunk zipper pull for use in concealed zippers, including a base plate;

[0008] The base plate has a core column at its top, a partition plate at its top, an elephant trunk buckle at one top end of the partition plate, a positioning groove at the other top end of the partition plate, a storage groove at the bottom end of the elephant trunk buckle, a limiting post that matches the positioning groove slidingly inside the storage groove, an outer edge protrusion at the bottom outer side of the limiting post, and a baffle that matches the storage groove at the top of the limiting post.

[0009] As a further embodiment of this utility model, the shape of the partition plate is teardrop-shaped.

[0010] As a further embodiment of this utility model: the bottom plate is provided with binding side plates on both sides of the top, and the binding side plates are provided with an upper plate on the top.

[0011] As a further embodiment of this utility model: there is a notch between the upper plate and the partition plate, and the notch is Y-shaped.

[0012] As a further embodiment of this utility model, the edges of the elephant trunk pull head are designed with rounded corners.

[0013] The beneficial effects of this utility model are:

[0014] During assembly, the limiting post can be lifted into the storage groove, and then the pull tab is assembled into the elephant trunk buckle. The elephant trunk buckle is then squeezed to bend it. At this time, the limiting post is inserted into the positioning groove, which blocks the pull tab. The bending of the elephant trunk buckle further reduces the vertical movement distance of the limiting post. Therefore, even if a gap appears between the limiting post and the partition plate later, this gap will be much smaller than the thickness of the pull tab. This ensures that the pull tab will not fall off after assembly, while further reducing the bending degree of the elephant trunk buckle, thereby reducing its deformation and preventing the coating from peeling off. This allows the elephant trunk zipper to be painted or electroplated during the production process, further expanding the processing methods of the N466 type invisible zipper.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] As shown in Figures 1-3, an elephant trunk zipper pull for use with invisible zippers includes a base plate 1. The base plate 1 is the main structure of the elephant trunk zipper pull and provides an installation position for other structures, ensuring the stability of other structures during use.

[0022] A base core column 2 is provided on the top of the base plate 1, and a partition plate 3 is provided on the top of the base core column 2. The partition plate 3 is teardrop-shaped, with an elephant trunk buckle 4 at one end of the top of the partition plate 3 and a positioning groove 5 at the other end. A storage groove 6 is provided at the bottom of the elephant trunk buckle 4, and a limiting post 7 matching the positioning groove 5 is slidably installed inside the storage groove 6. An outer edge protrusion 8 is provided on the outer side of the bottom end of the limiting post 7, and a baffle 9 matching the storage groove 6 is provided on the top of the limiting post 7. During assembly, the worker can lift the limiting post 7 into the storage groove 6. The outer edge protrusion 8 provides a good point of leverage for the worker when the limiting post 7 moves, thus facilitating the worker to adjust the limiting post 7. When the limiting post 7 is adjusted to a certain position... Afterwards, there will be a large gap between its bottom end and the partition plate 3. At this time, the pull tab can be assembled into the elephant trunk buckle 4, and then the elephant trunk buckle 4 is squeezed to make it bend. At this time, the limiting post 7 is inserted into the positioning groove 5 to block the pull tab. Since the elephant trunk buckle 4 bends, the vertical movement distance of the limiting post 7 is further reduced. So even if the limiting post 7 shakes up and down in the later stage, resulting in a certain gap between the lower end of the limiting post 7 and the partition plate 3, this gap will be much smaller than the thickness of the pull tab, ensuring that the pull tab will not fall off after assembly, and further reducing the degree of bending of the elephant trunk buckle 4, thereby reducing the deformation. This allows the elephant trunk pull head to be painted or electroplated during the production process, further avoiding the peeling of the coating in the later stage.

[0023] In this embodiment, specifically, binding side plates 10 are provided on both sides of the top of the base plate 1, and an upper plate 11 is provided on the top of the binding side plates 10. After the elephant trunk zipper is assembled onto the invisible zipper, the binding side plates 10 can compress and bind the invisible zipper from both sides, thereby ensuring the normal engagement of the invisible zipper. The binding side plates 10 support the upper plate 11, and the upper plate 11 binds the invisible zipper from the top. Together with the binding side plates 10, the invisible zipper can be covered from the outside, thereby providing good protection for the invisible zipper, preventing damage from the outside during use, and helping to extend the service life of the invisible zipper.

[0024] In this embodiment, specifically, there is a notch 12 distributed between the upper plate 11 and the partition plate 3. The notch 12 is Y-shaped. The notch 12 divides the traditional elephant trunk zipper head into two parts, which not only ensures that the invisible zipper can be well restrained after assembly, but also further reduces the materials required for product production and further reduces production costs.

[0025] In this embodiment, specifically, the edges of the elephant trunk zipper are rounded. After the elephant trunk zipper is assembled onto the invisible zipper, the rounded edges can minimize friction with the invisible zipper fabric, making it less likely to damage the fabric. While providing good protection for the fabric, it also further improves the smoothness of the elephant trunk zipper when pulled.

[0026] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
