Abstract
Description
Technical Field
[0001] The utility model relates to zipper technology, in particular to a non-blocking invisible zipper. Background Art
[0002] Existing invisible zippers usually use invisible sliders. In order to be hidden in the chain belt, the volume of conventional invisible sliders is usually small, and thus the structure adopted is relatively simple. In the invisible slider, the shaft portion of the pull tab is usually pivotally arranged in the shaft hole of the pull tab mounting portion, and there is usually a gap between the shaft hole and the shaft portion of the pull tab. Therefore, the pull tab is prone to shaking on the slider, affecting the user experience. In order to solve the above problem, some products on the market currently place rolling parts or rubber parts in the shaft hole, and use the rolling parts or rubber parts to squeeze the rotating shaft of the pull tab to maintain the position of the pull tab. However, this structure has certain defects. The rolling parts or rubber parts are independently placed in the shaft hole, and are only squeezed and fixed by the shaft portion of the pull tab after the pull tab is installed. During the installation of the pull tab, the rolling parts or rubber parts are easy to fall out, and the installation is inconvenient. Summary of the invention
[0003] In view of this, an object of the present invention is to provide a quick-release zipper.

[0028] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.
[0029] Implementation method 1:
[0030] like Figure 1 and Figure 2 The illustrated non-blocking invisible zipper comprises a pull tab 1, a pull tab body 2 and a needle tooth set 3. The pull tab 1 is a pull tab in a conventional zipper and will not be specifically described here. The pull tab 1 has a shaft portion 4. The pull tab 1 is rotatably arranged on the pull tab body 2 with the shaft portion as a rotation axis. The pull tab body 2 is a pull tab body used in a conventional invisible zipper. Specifically, the pull tab comprises an upper ship plate, a lower ship plate and a support core. The upper surface of the upper ship plate of the pull tab body 2 has a pair of vertical needle teeth 5. The pair of needle teeth 5 are relatively arranged in the length direction of the pull tab body 2. The length direction is the front-to-back direction when the slider is laid flat, and the space between a pair of needle teeth 5 is a storage space for accommodating the shaft of the pull tab 1. When the pull tab 1 is not installed on the slider body 2, the needle teeth 5 are in an upright state. During the installation of the pull tab, the shaft of the pull tab 1 is first placed in the storage space, and then the pair of needle teeth 5 are riveted. The specific process is as follows: an impact force is applied to the needle teeth 5, so that the top ends of the pair of needle teeth 5 are plastically deformed and approach each other, thereby limiting the shaft of the pull tab 1 in the storage space.
[0031] The side where the pair of needle teeth 5 face each other is defined as the inner side, and the side where the pair of needle teeth 5 face away from each other is defined as the outer side.
[0032] The needle tooth kit 3 is installed on at least one needle tooth 5. The needle tooth kit 3 has an extrusion structure 6 and a needle tooth mounting structure 7. The extrusion structure 6 is used to frictionally contact the shaft of the pull tab 1 so that the pull tab 1 can maintain a specific posture, such as an inclined posture or an inverted posture. The extrusion structure 6 is located in the accommodating space. When the pull tab 1 is installed in the accommodating space, the extrusion structure 6 abuts against the shaft of the pull tab 1. The needle tooth mounting structure 7 is used to be fixed to the needle tooth 5. When the needle tooth kit 3 is sleeved on the needle tooth 5, the needle tooth mounting structure 7 abuts against both sides of the needle tooth 5 in the width direction. The width direction is the left and right sides of the pull head body 2 when the pull head body 2 is placed flat.
[0033] In the present embodiment, the number of the needle tooth kit 3 is one, and the needle tooth kit 3 is a thin shell-shaped elastomer made of elastic material. Specifically, the elastic material used in the present embodiment is resin. The needle tooth mounting structure 7 is sleeved on a needle tooth 5. Specifically, in the present embodiment, the needle tooth mounting structure 7 is sleeved on the front needle tooth 5. The shape of the needle tooth mounting structure 7 matches the shape of the needle tooth 5. When the needle tooth mounting structure 7 is sleeved on the needle tooth 5, the needle tooth 5 is exposed at the top of the needle tooth mounting structure 7. The needle tooth mounting structure 7 only surrounds the root of the needle tooth 5. The design of this structure The needle tooth 5 will not be disturbed by the needle tooth mounting structure 7 during the process of plastic deformation caused by the impact force. In addition, the mounting structure is provided with an opening at the outer position corresponding to the needle tooth 5. The opening enables the needle tooth kit 3 to surround the periphery of the needle tooth 5 in a semi-enclosed state. Compared with the fully enclosed structure, the needle tooth kit 3 of the semi-enclosed structure is not easy to deform or even break with the deformation of the needle tooth during the riveting process of the needle tooth 5. The extrusion structure 6 is L-shaped, and the extrusion structure 6 covers the bottom of the accommodating space and the inner side surface of the needle tooth 5 where the needle tooth mounting structure 7 is located. Figure 3 As shown, after the pin teeth 5 are riveted, the extrusion structure 6 abuts against the shaft of the pull tab 1 at the inner side of one pin tooth 5 and the bottom of the accommodating space.
[0034] Implementation method 2:
[0035] like Figure 4 and Figure 5 As shown, the difference between this embodiment and the first embodiment is that the needle tooth mounting structure 7 is sleeved on the two needle teeth 5. Specifically, the number of the needle tooth kit 3 is the same as that in the first embodiment, which is one. In this embodiment, the needle tooth kit 3 has two needle tooth mounting structures 7. The shapes of the two needle tooth mounting structures 7 match the shapes of the two needle teeth 5. The extrusion structure 6 is located between the two needle tooth mounting structures 7. When the needle tooth kit 3 is installed on the slider body 2, the extrusion structure 6 covers the inner sides of the two needle teeth 5 and the bottom of the accommodating space. Figure 6 As shown, after the pin teeth 5 are riveted, the extrusion structure 6 abuts against the shaft of the pull tab 1 at the inner sides of the two pin teeth 5 and the bottom of the accommodating space.
[0036] Implementation method three:
[0037] like Figure 7 and Figure 8 As shown, the difference between this embodiment and the second embodiment is that: the number of needle tooth sets 3 is two, the shapes of the two needle tooth sets 3 match the shapes of the two needle teeth 5, and the extrusion structure of each needle tooth set 3 is a side surface that matches the inner side of the needle tooth 5. When the needle tooth set 3 is installed on the slider body 2, the extrusion structure 6 only covers the inner side of the corresponding needle tooth 5, such as Fig. 9 As shown, after the pin teeth 5 are riveted, the extrusion structure 6 abuts against the shaft of the pull tab 1 on the inner sides of the two pin teeth 5 .
[0038] Implementation method 4:
[0039] like Fig.10 As shown, the difference between this embodiment and the third embodiment is that: the mounting structure does not have an opening at the outer position of the needle tooth 5, and the needle tooth kit surrounds the circumference of the needle tooth 5 in a fully surrounded state. Preferably, the needle tooth kit is a circular ring of elastic material, and the portion of the circular ring corresponding to the two needle teeth on the opposite side of the needle teeth is an extrusion structure 6, and the portion of the circular ring other than the extrusion structure is a needle tooth mounting structure 7. The needle tooth kit adopts a circular ring structure with the following advantages: the horizontal cross-section of the needle teeth of the existing pull head cylinder is mostly rectangular, and the needle tooth kit with a circular ring structure is easy to be mounted on the outside of the needle teeth 5, which is more convenient to install; and when the needle tooth kit 3 with a circular ring structure is mounted on the outside of the needle teeth with a rectangular cross-section, there is a large gap between the needle tooth kit 3 and the needle teeth 5. When the needle teeth 5 are riveted, the above gap can provide deformation space for the needle teeth 5.
