Description

Technical Field

[0001] This utility model relates to zipper assembly auxiliary tools, and more particularly to an auxiliary plate assembly for zipper assembly. Background Technology

[0002] Zippers, as a widely used mechanical opening and closing device, are commonly found in products such as clothing, bags, and tents. The assembly of the zipper head is a key process in the zipper manufacturing process.

[0003] Currently, although there are mechanized operations for zipper assembly, small-scale factories still generally use manual assembly to complete the assembly of zipper heads due to limitations in cost, technology, and production scale.

[0004] When manually installing a zipper pull, the zipper pull must first be inserted into the front end of the zipper teeth on one side of the zipper. Then, the other side of the zipper is lifted and inserted into the zipper pull side by side. Finally, a pushing or pulling force is applied to make the zipper pull evenly engage the zippers on both sides and complete the closure. This method has the following drawbacks:

[0005] 1. The zipper heads on both sides are not easy to insert at the same time, which often causes the zippers on both sides to be crooked and unable to close properly, thus requiring rework.

[0006] 2. Prolonged manual operation can easily lead to fatigue, which in turn affects work efficiency.

[0007] Based on the above, it is necessary to improve the purely manual operation method in order to improve work efficiency to a certain extent. Utility Model Content

[0008] To address the above issues and overcome the shortcomings of existing technologies, this invention simplifies the zipper head installation process while simultaneously securing the zipper head. In this invention, the receiving cavity for securing the zipper head restricts the position and tilt angle of the zipper head, allowing zippers from both sides to be inserted into the zipper head side-by-side simultaneously, with an insertion angle more user-friendly. When the zipper head specifications need to be changed, only the movable plate needs to be replaced. This improves product utilization and saves on tool manufacturing costs.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] This utility model provides an auxiliary plate assembly for zipper assembly, comprising:

[0011] The substrate has multiple cantilever arms on its front side and a clamping part on its rear side for engaging with the edge of a desktop; the multiple cantilever arms are arranged at preset distances, and an installation space is formed between adjacent cantilever arms.

[0012] A movable plate, which is movably inserted into the installation space;

[0013] in,

[0014] The movable plate has a receiving cavity for accommodating the zipper head;

[0015] The cantilever is provided with a guide rail on the side facing the installation space, and correspondingly, the movable plate is provided with a sliding groove on the side facing the cantilever. The movable plate can be freely inserted into the installation space through the cooperation of the guide rail and the sliding groove.

[0016] The receiving cavity includes a limiting part and a through part.

[0017] The angle between the direction of the limiting part and the through part and the horizontal plane is 60°-80°.

[0018] The guide rail has a spring pin on its front side; correspondingly, the slide groove has a positioning hole on its front side.

[0019] The length of the chute is 0.6-0.8 times the length of the movable plate, and the depth is 2-3 mm; the positioning hole is 1-2 mm deeper than the bottom surface of the chute.

[0020] The height of the guide rail is 0.5-1mm less than the depth of the slide groove; the height of the elastic pin is 0.5-1mm less than the depth of the positioning hole.

[0021] The clamping part is hook-shaped, and the angle between the hook of the clamping part and the horizontal plane is 20°-30°.

[0022] The end of the hook of the clamping part is a smooth part, and the smooth part is coated with a polyurethane coating or a polytetrafluoroethylene coating.

[0023] The clamping part is made of nylon, polyester or polypropylene, with a thickness of 0.5-1cm.

[0024] The substrate has at least four mounting spaces.

[0025] The embodiments of this utility model have at least the following advantages or beneficial effects:

[0026] (1) The zipper assembly auxiliary plate of this application includes a base plate and a movable plate. The movable plate has a receiving cavity in which the zipper head can be placed. After the zipper head is placed into the receiving cavity, the zipper head is restricted from translating or rotating. At this time, the left and right zippers are simultaneously inserted into the zipper head. In this way, while ensuring that the zippers are aligned and reducing the phenomenon of zipper skew, work efficiency is improved.

[0027] (2) In the zipper assembly auxiliary plate assembly of this application, the movable plate is a detachable part, and the receiving cavity of each movable plate corresponds to a zipper head actually produced. When the user needs to replace the produced zipper head, only the movable plate needs to be produced and replaced. In this way, the base plate does not need to be replaced, saving production materials. Attached Figure Description

[0039] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the present invention.

[0040] In the description of the embodiments of this utility model, it should be understood that the terms "lateral", "up", "down", "left", "right", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0041] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0042] The embodiments of this utility model will be described in detail below.

[0043] This utility model provides an auxiliary plate assembly for zipper assembly:

[0044] like Figure 1 As shown, the zipper assembly auxiliary plate includes a base plate 1 and a movable plate 2. The base plate 1 has multiple cantilever arms 102 on its front side and a clamping part 101 on its rear side for engaging with the edge of a tabletop. The multiple cantilever arms 102 are arranged at preset intervals, forming an installation space 103 between adjacent cantilever arms 102. The multiple movable plates 2 are installed in the installation space 103 formed by the cantilever arms 102 of the base plate 1. In use, the zipper head 3 is placed in the receiving cavity 201 of the movable plate 2.

[0045] Specifically, such as Figure 2 As shown, the front side of the base plate 1 has multiple cantilever arms 102, and each cantilever arm 102 has a guide rail 1021 and an elastic pin 1022 on both its left and right sides. The length and width of the guide rail 1021 are the same as the length and width of the groove 202 of the movable plate 2, and the height of the guide rail is 0.5-1mm less than the depth of the groove; the height of the elastic pin is 0.5-1mm less than the depth of the positioning hole. In this way, while guiding and limiting the movable plate 2, there will be no tight fit between the base plate 1 and the movable plate 2, thus preventing any interference with the pushing and pulling of the movable plate 2.

[0046] A clamping part 101 is located on the rear side of the substrate 1. The clamping part 101 has a hook shape in its side view. The angle between the end of the clamping part 101 and the horizontal plane is 20°-30°. This allows the clamping part 101 to clamp the tabletop by deformation. The clamping part 101 is made of nylon, polyester, or polypropylene, with a thickness of 0.5-1 cm. This makes the clamping part 101 flexible. In use, the end of the clamping part 101 is pulled downwards and clamped onto the workbench table to achieve fixed constraint on the substrate 1. Furthermore, the hook of the clamping part 101 has a smooth part 1011, which is arc-shaped and coated with a polyurethane coating or a polytetrafluoroethylene coating. This allows the substrate 1 to be directly pushed and pulled during installation or removal without leaving scratches or producing harsh noise on the workbench table.

[0047] like Figures 4-5 As shown, both sides of the movable plate 2 have sliding grooves 202 and positioning holes 203. The length of the sliding groove 202 is the same as the length of the guide rail 1021 on the base plate 1, and its length is 0.6-0.8 times the length of the movable plate 2. The depth of the sliding groove 202 is 2-3 mm. The positioning hole 203 is located at the end of the sliding groove 202, opposite to the position of the elastic pin 1022 in the base plate 1. The depth of the positioning hole 203 is 1-2 mm deeper than the bottom surface of the sliding groove 202. In this way, when installing the movable plate 2, the slide groove 202 is held in place on the guide rail 1021. Then, the movable plate 2 is pushed, and it slides horizontally under the constraint of the guide rail 1021 and the slide groove 202 until the elastic pin 1022 is inserted into the positioning hole 203. The elastic pin 1022, to a certain extent, fixes the movable plate 2, allowing it to be stably placed in the installation space 103 without external force. When external force is applied, the movable plate 2 can be dislodged from the installation space 103 along the limiting direction of the guide rail 1021. For example, when disassembling the movable plate 2, simply pull the movable plate 2 outward to dislodge the elastic pin 1022 from the positioning hole 203, and the movable plate 2 will then be withdrawn outward under the constraint of the guide rail 1021 and the slide groove 202.

[0048] Specifically, such as Figure 6 As shown, the receiving cavity 201 on the movable plate 2 is inclined. The angle between the direction of the receiving cavity 201 and the horizontal plane is 60°-80°. In this way, the tilt angle of the zipper head 3 is also 60°-80°, which is more in line with actual application scenarios compared to the horizontal or vertical state, and will not cause excessive fatigue for manual use for a long time. Furthermore, the receiving cavity 201 is irregularly shaped, specifically divided into a limiting part 2011 and a through part 2012. In use, the zipper head 3 is tilted and inserted. At this time, the zipper head 3 will not fall downward under the restriction of the limiting part 2011. When the two zippers are inserted side by side into the zipper head 3, the zippers will be interlocked by the zipper head 3 and then pass out from the bottom of the through part 2012.

[0049] Furthermore, each type of movable plate 2 has a corresponding receiving cavity 201 for a zipper head 3. When the specifications of the zipper head 3 to be assembled change, it is only necessary to re-press the receiving cavity 201 on the movable plate 2 and then replace the movable plate 2 corresponding to the target zipper head 3 on the base plate 1. This not only improves the production efficiency of auxiliary tools but also saves material resources.

[0050] When using the zipper assembly auxiliary plate assembly of this utility model, the following usage methods are preferred:

[0051] Step 1: Manually pull the end of the clamping part 101 on the substrate 1 so that the clamping part 101 bends and fits onto the edge of the workbench table. Then push the substrate 1 until it is completely in contact with the table.

[0052] Step 2: Select the target movable plate 2, align the slide groove 202 on the movable plate 2 with the guide rail 1021 on the side of the cantilever 102, so that the slide groove 2022 and the guide rail 1021 cooperate, and push the movable plate 2 until the elastic pin 1022 slides into the positioning hole 203.

[0053] Step 3: Place the zipper head 3 into the receiving cavity 201 of the movable plate 2, and simultaneously thread the zipper into both sides of the zipper head 3. At this time, the zipper will emerge from the through part 2012. Lift the zipper head 3 to complete the zipper assembly.

[0054] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
