Description

Technical Field

[0001] This utility model relates to the field of zipper technology, and more specifically to a lockless zipper pull with a hanging cord. Background Technology

[0002] Traditional zipper pulls typically have a riveted tab attached to them for opening and closing the zipper. However, to meet market demands for lightweight and low-cost solutions, lighter, cordless (tethered) zipper pulls have been designed. These pulls use a webbing or rope attached to the zipper pull instead of the traditional tab.

[0003] Currently, this type of zipper pull typically has two uprights and a crossbar on the upper deck to form the attachment part for hanging ropes. However, due to its unique structure, this U-shaped structure of two uprights and a crossbar can usually only be attached to the upper deck of the zipper pull by riveting or injection molding. Riveting makes the manufacturing process of the zipper pull complex, while injection molding is costly due to the complexity of the U-shaped structure and is prone to producing rough edges. Utility Model Content

[0004] The purpose of this utility model is to provide a lockless lanyard pull head to solve the problems of complex structure, complicated manufacturing process, and high cost of the existing lockless lanyard pull heads.

[0005] The present invention adopts the following technical solution:

[0006] A lockless lanyard puller includes a puller body. The upper and / or lower lanyard of the puller body is provided with a pull nose. The pull nose is integrally formed by a base, a middle part and a tail. The base protrudes from the front end of the upper and / or lower lanyard, and the middle part extends from the base to the rear end of the puller. The middle part is hollowed out in the middle and forms a hollow cavity with the tail for attaching a lanyard.

[0007] Furthermore, the tail extends downward toward the upper and / or lower deck of the pull head body.

[0008] Preferably, the pull head body and the base, middle and tail of the pull nose are integrally die-cast.

[0009] Furthermore, the inner surface of the hollow cavity is a relatively inclined plane or a relatively parallel plane.

[0010] Furthermore, the base protrudes from the front end of the upper and / or lower hull plates to form a vertical surface, a slope, or a transitional arc surface.

[0011] Furthermore, the top end of the nose base is provided with a bevel or an arc surface.

[0012] Furthermore, the hanging rod at the tail end is lower than the two sides of the middle part, forming a stepped surface or arc-shaped groove for fixing the rope.

[0013] Furthermore, the tail section has a gap with the upper and / or lower decks to facilitate securing the ropes.

[0014] Preferably, the interval is greater than or equal to 2 mm.

[0015] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages:

[0016] 1. The pull nose of this utility model is integrally formed from the base, middle and tail. Its pull nose protrudes from the front end of the upper and / or lower boat plate and extends backward. Compared with the existing lockless rope pull head with protruding uprights on both sides, the product structure is simpler, which not only ensures the stability of the product connection structure, making it sturdy and durable, but also simplifies the production process and reduces manufacturing costs.

[0017] 2. The nose of this utility model is in the shape of an arc hook. It can be formed by one-piece die casting, which is simpler and cheaper. It does not require riveting and assembly, nor does it require complex and expensive molds, thus reducing production steps and production costs.

[0018] 3. The pull nose of this utility model has a hollow structure, which saves materials, reduces the weight of the pull head, and makes the appearance more beautiful and visually impactful.

[0019] 4. The details of the nose pull structure of this utility model have been optimized. An arc-shaped structure is preferred at the base and middle of the nose pull, making the product structure more robust and reliable.

[0020] 5. The top of the base of the nose puller (i.e., the transition between the base and the middle) of this utility model is provided with a slope or arc surface to avoid scratching; the hanging rod at the tail of the nose puller is lower than the middle, forming a stepped surface or arc groove to facilitate fixing the rope. Attached Figure Description

[0021] Figure 1 This is the front view of the present utility model.

[0022] Figure 2 This is a three-dimensional structural diagram of the present invention.

[0023] Figure 3 This is a three-dimensional structural schematic diagram of the present invention from another perspective.

[0024] The components in the diagram are labeled as follows: pull head body 10, upper boat plate 11, lower boat plate 12, connecting column 13, pull nose 20, base 21, middle part 22, tail part 23, hollow cavity 24, stepped surface 25, and rope 30. Detailed Implementation

[0025] The specific implementation of the present invention will now be described with reference to the accompanying drawings.

[0026] Reference Figure 1 A lockless lanyard pull head includes a pull head body 10, which can be a traditional pull head or a double-sided pull head. It includes an upper boat plate 11, a lower boat plate 12 and a connecting post 13. The specific structure is basically the same as that of existing pull heads, and will not be described in detail here.

[0027] Reference Figures 1 to 3 The upper plate 11 and / or lower plate 12 of the pull head body 10 are provided with a pull nose 20. The pull nose 20 is integrally formed by a base 21, a middle part 22 and a tail part 23. The base 21 protrudes from the front end of the upper plate 11 and / or lower plate 12, and the middle part 22 extends from the base 21 to the rear end of the pull head. The middle part 22 is hollowed out in the middle and forms a hollow cavity 24 with the tail part 23 for attaching the rope 30.

[0028] That is, the zipper body 10 of the present invention can be a conventional zipper with a single zipper nose 20, or a double-sided zipper with two zipper noses 20. In this embodiment, it is preferred to be a conventional zipper with a single zipper nose 20, and more preferably, the zipper nose 20 is designed on the upper part of the zipper body.

[0029] Specifically, refer to Figure 2 and Figure 3 The pull head body 10 is integrally die-cast with the base 21, middle 22 and tail 23 of the pull nose 20. The pull nose 20 is formed in an arc shape, facing downwards and upwards towards the ship plate 11, like a hook. The pull nose 20 is hollowed out at the top and bottom, that is, the hollow cavity 24 in the middle 22 of the pull nose 20 has a relatively inclined or relatively parallel plane. The inclined surface can be a slope that is larger at the top and smaller at the bottom, or a slope that is smaller at the top and larger at the bottom.

[0030] Reference Figure 2 and Figure 3 The base 21 of the nose 20 protrudes from the front end of the upper hull plate 11 and / or the lower hull plate 12, forming a vertical surface, a slope, or a transitional arc surface. The slope or arc surface is either larger at the bottom and smaller at the top or smaller at the bottom and larger at the top. In this embodiment, the base 21 preferably protrudes upward from the upper hull plate 11, forming an arc-shaped transition surface that is larger at the bottom and smaller at the top, and is smoothly connected to the upper hull plate 11. To avoid scratches, this embodiment provides a slope or arc surface (not shown in the figure) at the top of the base 21 (i.e., the transition between the base 21 and the middle part 22).

[0031] Reference Figure 2 and Figure 3 The tail 23 of the nose pull 20 is integrally formed with the middle part 22 of the nose pull 20 on the hollow cavity 24 in a structure similar to a hanging rod. The hanging rod of the tail 23 is lower than the sides of the middle part 22, forming a stepped surface 25 or an arc-shaped groove for fixing the rope 30. In addition, in order to facilitate fixing the rope 30, there is a certain gap between the tail 23 and the upper boat plate 11 and / or the lower boat plate 12. Preferably, this gap is greater than or equal to 2mm.

[0032] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
