Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a zipper quick-release upper stop assembly. Background Art

[0002] The traditional zipper upper stop is installed at the end of the zipper. Its main function is to prevent the slider from separating from the teeth during the zipping process. When the slider is damaged, due to the existence of the traditional zipper upper stop, the slider cannot be replaced. Content of the Utility Model

[0003] The utility model solves the problems in the related art and provides a zipper quick-release upper stop assembly, which can realize three states: normal use state, emergency state, and slider replacement state, facilitating the replacement of the slider.

[0004] To solve the above technical problems, the utility model is realized through the following technical solutions: A zipper quick-release upper stop assembly includes a left upper stop code assembly installed on the left tape and a right upper stop code assembly installed on the right tape. The left upper stop code assembly includes a first extrusion upper stop code; the right upper stop code assembly includes a second extrusion upper stop code, an intermediate upper stop code, and a quick-release upper stop code arranged from bottom to top. The installation height of the first extrusion upper stop code is higher than that of the second extrusion upper stop code and lower than that of the intermediate upper stop code. A quick-release groove is opened on the quick-release upper stop code.

[0005] As a preferred solution, one end of the left upper stop code assembly and the right upper stop code assembly is provided with a communicating installation groove and a relief opening, and the other end of the left upper stop code assembly and the right upper stop code assembly is provided with a groove.

[0006] As a preferred solution, an extrusion hole is opened on one side of the first extrusion upper stop code and the second extrusion upper stop code with a groove.

[0007] As a preferred solution, one end of the first extrusion upper stop code and the second extrusion upper stop code with a groove is narrower than the end with the installation groove, and the narrow ends of the first extrusion upper stop code and the second extrusion upper stop code have smooth ends.

[0008] As a preferred solution, the quick-release groove is opened on the upper and lower surfaces of the quick-release upper stop code and penetrates from the left side to the right side. The quick-release groove includes a connected narrow part and a wide part. The narrow part is inclined, and the slider is removed through the narrow part and from the wide part.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model can achieve three states, namely, the normal use state, the emergency state, and the slider replacement state. In the normal use state, when the slider moves upward to the upper stop position, the combined width of the upper left stop code assembly and the upper right stop code assembly is greater than the caliber width of the slider. The slider stops at the upper right stop code assembly and the upper left stop code assembly. When the slider moves downward, the slider leaves the upper right stop code assembly and the upper left stop code assembly, and the left chain teeth and the right chain teeth can be separated under the action of the slider. In the emergency state, under the action of an upward force (about 18 - 40 N), the first extrusion upper stop code and the second extrusion upper stop code are deformed under pressure. The slider presses the first extrusion upper stop code and the second extrusion upper stop code, and the combined width of the deformed upper left stop code assembly and the upper right stop code assembly is equal to the caliber width of the slider. The slider passes through the upper left stop code assembly and stays at the emergency stop position of the upper right stop code assembly of the slider. After the slider is damaged, it can be disassembled through the quick release groove for replacement. Description of the Drawings

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present utility model and its application or use. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0020] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0021] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present utility model. At the same time, it should be understood that for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationship. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the authorized specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0022] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be construed as limiting the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0023] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper", etc. can be used here to describe the spatial positional relationship of a device or feature shown in the figure with other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figure for the device.

Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0024] In addition, it should be noted that the use of terms such as "first", "second", etc. to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present utility model.

[0025] As Figures 1 to 7 shown, a zipper quick-release upper stop assembly includes a left upper stop code assembly installed on the left tape 5 and a right upper stop code assembly installed on the right tape 6. The left upper stop code assembly includes a first extrusion upper stop code 1; the right upper stop code assembly includes a second extrusion upper stop code 2, an intermediate upper stop code 3, and a quick-release upper stop code 4 arranged from bottom to top. The installation height of the first extrusion upper stop code 1 is higher than that of the second extrusion upper stop code 2 and lower than that of the intermediate upper stop code 3. When extruded, the end 13 of the first extrusion upper stop code 1 extrudes the second extrusion upper stop code 2, and the end 13 of the second upper stop code 2 extrudes the first extrusion upper stop code 1; the quick-release upper stop code 4 is in an inverted L-shaped structure, and a quick-release groove 7 is formed on the quick-release upper stop code 4. When the pull head 12 is damaged, the pull head 12 can be removed through the quick-release groove 7 for replacement.

[0026] In one embodiment, mounting grooves 8 and relief openings 9 that communicate with each other are provided at one end of the upper left stop code assembly and the upper right stop code assembly. The mounting groove 8 is a circular groove, and the relief opening 9 is elongated. The mounting groove 8 and the relief opening 9 are both distributed along the vertical direction of the upper left stop code assembly and the upper right stop code assembly, facilitating installation. When installing the upper left stop code assembly and the upper right stop code assembly, they are installed on the left tape 5 and the right tape 6 through the relief opening 9 and the mounting groove 8. Grooves 10 are provided at the other end of the upper left stop code assembly and the upper right stop code assembly, that is, arc-shaped grooves 10 are provided at the opposite ends of the first pressing upper stop code 1, the second pressing upper stop code 2, the middle upper stop code 3, and the quick-release upper stop code 4. For the first pressing upper stop code 1 and the second pressing upper stop code 2, their grooves 10 will be squeezed by the ends of the corresponding second pressing upper stop code 2 and the first pressing upper stop code 1.

[0027] In one embodiment, pressing holes 11 are provided on the sides of the first pressing upper stop code 1 and the second pressing upper stop code 2 that have the grooves 10, so that the first pressing upper stop code 1 and the second pressing upper stop code 2 can be deformed by pressing, thereby reducing the combined width of the upper left stop code assembly and the upper right stop code assembly.

[0028] In one embodiment, the end of the first pressing upper stop code 1 and the second pressing upper stop code 2 that has the groove 10 is narrower than the end that has the mounting groove 8. The narrow ends of the first pressing upper stop code 1 and the second pressing upper stop code 2 have smooth ends 13, and their shapes exactly match the grooves 10, so that the corresponding grooves 10 can be squeezed.

[0029] In one embodiment, the quick-release groove 7 is provided on the upper and lower surfaces of the quick-release upper stop code 4 and penetrates from the left side to the right side. The quick-release groove 7 is surrounded by an inclined surface 73 and an irregular surface 74. Among them, the irregular surface 74 includes an arc-shaped surface I, a vertical surface connected to the arc-shaped surface and extending upward, and an arc-shaped surface II connected to the vertical surface and extending to the right side. Among them, the arc-shaped surface I and the inclined surface 73 enclose a narrow part 71, and the vertical surface, the arc-shaped surface II and the inclined surface 73 enclose a wide part 72. The narrow part 71 is inclined, and the narrow part 71 communicates with the wide part 72. The slider 12 is removed through the narrow part 71 and from the wide part 72.

[0030] As Figure 4 shown, in the normal use state, when the slider 12 reaches the upper stop position upward, the combined width of the upper left stop code assembly and the upper right stop code assembly is greater than the caliber width of the slider 12. The slider 12 stops at the upper right stop code assembly and the upper left stop code assembly. When the slider 12 moves downward, the slider 12 leaves the upper right stop code assembly and the upper left stop code assembly. The left chain teeth and the right chain teeth can be separated under the action of the slider 12.

[0031] As Figure 5As shown, in an emergency state, under the action of an upward force (about 18 - 40 N), the first extrusion upper stop 1 and the second extrusion upper stop 2 are deformed under pressure. The pull head 12 squeezes the first extrusion upper stop 1 and the second extrusion upper stop 2, and the combined width of the deformed left upper stop assembly and the right upper stop assembly is equal to the caliber width of the pull head 12. The pull head 12 passes through the left upper stop assembly and the pull head 12 stays at the Figure 6 emergency stop position of the pull head of the right upper stop assembly as shown.

[0032] After the pull head 12 is damaged, as Figure 7 shown, the pull head 12 is disassembled from the quick release groove 7, and at the same time, a new pull head 12 is reinstalled through the quick release groove 7 to keep the use function of the zipper unchanged.

[0033] The above is the preferred embodiment of the present utility model. Those skilled in the art of the present utility model can also make changes and modifications to the above embodiment. Therefore, the present utility model is not limited to the above specific embodiments, and any obvious improvements, substitutions or variations made by those skilled in the art on the basis of the present utility model all fall within the protection scope of the present utility model.
