Description

Technical Field

[0001] This utility model belongs to the technical field of zipper manufacturing, specifically relating to an anti-pinch zipper. Background Technology

[0002] Today, zippers, as connectors that enable items to be securely joined together, are widely used in clothing, packaging and other fields due to their flexibility. There are many types of zippers on the market, including nylon zippers, invisible zippers, and resin zippers.

[0003] In the process of developing this utility model, the inventors discovered at least the following problems in the prior art.

[0004] During use, existing zippers can easily trap fabric or skin between the teeth, causing damage to the zipper and even skin injuries to the user. Utility Model Content

[0005] The purpose of this invention is to provide an anti-pinch zipper that addresses the shortcomings of existing technologies. By optimizing the zipper structure, it can solve the problem of fabric or skin being easily caught in the zipper teeth.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anti-pinch zipper includes a zipper tape with teeth connected to a slider. Anti-pinch baffles are provided on the front and rear sides of the slider, with a gap of 0.5mm-1.5mm between the anti-pinch baffles and the teeth. A spring is provided between the anti-pinch baffles and the slider. The slider has symmetrically arranged guide grooves with an inclined angle inside, the projection of which overlaps with the projection of the anti-pinch baffles.

[0008] In some possible implementations, the spring is disposed on the side of the anti-pinch baffle near the zipper pull, and the spring is fixed between the anti-pinch baffle and the zipper pull by snap-fit.

[0009] In some possible implementations, the chain teeth have interlocking surfaces with a plurality of protrusions spaced apart, and the chain teeth of two adjacent zipper strips interlock with each other through the protrusions.

[0010] In some possible implementations, a pressure sensor is embedded inside the zipper head, and the detection end of the pressure sensor contacts the chain teeth.

[0011] In some possible implementations, the top of the slider is provided with an arc transition surface, which is perpendicular to the anti-pinch baffle.

[0012] In some possible implementations, the surface of the pull tab is coated with a hydrophobic nano-coating, and the inner surface of the flow channel is coated with a Teflon coating.

[0013] In some possible implementations, the zipper pull is integrally injection molded, and the corners of the zipper pull are rounded.

[0014] In some possible implementations, the outer diameter of the chain teeth is smaller than the outer diameter of the guide groove.

[0015] In some possible implementations, the tilt angle is 1°-5°.

[0016] In some possible implementations, the upper and lower sides of the zipper tape are respectively provided with an upper stop and a lower stop, and the upper or lower stops of two adjacent zipper tapes are connected by magnetic attraction.

[0017] One of the above technical solutions has the following beneficial effects.

[0018] This invention optimizes the zipper structure by designing anti-pinch baffles on the front and rear sides of the zipper pull. The anti-pinch baffles and the zipper teeth have a pre-defined gap to prevent the zipper tape from entering the meshing surface of the teeth. During zipper use, this prevents fabric or skin from being caught in the zipper teeth, thus solving the problem of fabric or skin easily getting caught. Additionally, a spring is designed between the anti-pinch baffles and the zipper pull, allowing the spring to reset and adjust the gap between the baffles and the zipper pull, further cushioning against external impacts. Furthermore, the zipper pull has symmetrical guide grooves inside, which, through a pre-defined tilt angle, guide the zipper tape to slide out to both sides, improving the smoothness of the zipper.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings, but this is not intended to limit the present invention.

[0035] Example 1

[0036] Because existing zippers can easily trap fabric or skin in the zipper teeth during use, causing damage to the zipper and even skin injuries to the user.

[0037] like Figure 1As shown, the anti-pinch zipper of this utility model includes a zipper belt 1, the zipper belt 1 is provided with chain teeth 2, and the chain teeth 2 are connected to a zipper head 3; anti-pinch baffles 4 are provided on the front and rear sides of the zipper head 3, and a gap of 0.5mm-1.5mm is formed between the anti-pinch baffles 4 and the chain teeth 2; a spring 5 is provided between the anti-pinch baffles 4 and the zipper head 3; the zipper head 3 is symmetrically provided with guide grooves 6 with an inclined angle inside, and the projection of the guide grooves 6 overlaps with the projection of the anti-pinch baffles 4. This invention optimizes the zipper structure by designing anti-pinch baffles 4 on the front and rear sides of the zipper pull, with a 0.5mm-1.5mm gap between the anti-pinch baffles 4 and the zipper teeth 2. This prevents the zipper tape 1 from entering the meshing surface of the zipper teeth 2. When the zipper is in use, it can prevent fabric or skin from being caught in the zipper teeth 2, thus solving the problem of fabric or skin being easily caught in the zipper teeth. At the same time, a spring 5 is designed between the anti-pinch baffles 4 and the zipper pull 3. The spring 5 can reset, that is, reset and adjust the gap between the anti-pinch baffles 4 and the zipper pull 3, which can also buffer external impacts. In addition, the zipper pull 3 has symmetrical guide grooves 6 inside, which can guide the zipper tape 1 to slide out to both sides by a preset tilt angle, which helps to improve the smoothness of the zipper.

[0038] It should be noted that the zipper pull 3 has an upper plate and a lower plate. One anti-pinch baffle 4 is positioned parallel or inclined above the upper plate, and the other anti-pinch baffle 4 is positioned parallel or inclined below the lower plate. The anti-pinch baffles 4 are arc-shaped baffles. The two anti-pinch baffles 4 work together to prevent fabric or skin from being pinched into the zipper teeth 2, thus preventing pinching. In use, the two zipper straps 1 are generally arranged side by side, and the zipper teeth 2 of the two zipper straps 1 interlock to achieve a tight seal between the zipper and the clothing. In addition, the side of the anti-pinch baffle 4 facing the zipper pull 3 has a concave structure, which creates a space between the anti-pinch baffle 4 and the zipper pull 3 to accommodate the spring 5, and also ensures that the gap between the anti-pinch baffle 4 and the zipper pull 3 meets the requirement of 0.5mm-1.5mm.

[0039] In the anti-pinch zipper according to this utility model, the spring 5 is disposed on the side of the anti-pinch baffle 4 near the zipper head 3, and the spring 5 is fixed between the anti-pinch baffle 4 and the zipper head 3 by snap-fit. Specifically, the spring 5 is pre-installed on the inner side of the anti-pinch baffle 4 and is fixedly connected to the zipper head 3 by a snap-fit.

[0040] In the anti-pinch zipper according to the present invention, the chain teeth 2 have an interlocking surface, and the interlocking surface is provided with a plurality of protrusions 21 at intervals. The chain teeth 2 of two adjacent zipper straps 1 interlock with each other through the protrusions 21, thereby increasing the closure stability and reducing the probability of two adjacent zipper straps 1 accidentally coming loose.

[0041] In the anti-pinch zipper according to this utility model, a pressure sensor is embedded inside the zipper pull 3, and the detection end of the thin-film pressure sensor contacts the zipper teeth 2. Specifically, the pressure sensor is preferably a thin-film pressure sensor, which is a commercially available model, and the detection end of the thin-film pressure sensor contacts the zipper teeth 2, enabling real-time detection of the force on the meshing area of ​​the zipper teeth 2. In some embodiments, a control chip that works with the pressure sensor can also be included; the control chip can be located inside the zipper tape 1.

[0042] In the anti-pinch zipper according to this utility model, the top of the zipper pull 3 is provided with an arc transition surface, which is perpendicular to the anti-pinch baffle 4. Specifically, adding the arc transition surface can reduce the frictional resistance with the zipper tape 1.

[0043] In the anti-pinch zipper according to the present invention, an upper stop 7 and a lower stop 8 are respectively provided on the upper and lower sides of the zipper tape 1. The upper stop 7 or lower stop 8 of two adjacent zipper tapes 1 are connected by magnetic attraction. The magnetic force is used to connect the upper stop 7 or lower stop 8 of two adjacent zipper tapes 1, which increases the closing stability, reduces the probability of two adjacent zipper tapes 1 accidentally coming loose, and can also help the chain teeth 2 to quickly align and engage.

[0044] The working principle of this utility model is as follows:

[0045] This invention optimizes the zipper structure by designing anti-pinch baffles 4 on the front and rear sides of the zipper pull, with a 0.5mm-1.5mm gap between the anti-pinch baffles 4 and the zipper teeth 2. This prevents the zipper tape 1 from entering the meshing surface of the zipper teeth 2. When the zipper is in use, it can prevent fabric or skin from being caught in the zipper teeth 2, thus solving the problem of fabric or skin being easily caught in the zipper teeth. At the same time, a spring 5 is designed between the anti-pinch baffles 4 and the zipper pull 3. The spring 5 can reset, that is, reset and adjust the gap between the anti-pinch baffles 4 and the zipper pull 3, which can also buffer external impacts. In addition, the zipper pull 3 has symmetrical guide grooves 6 inside, which can guide the zipper tape 1 to slide out to both sides by a preset tilt angle, which helps to improve the smoothness of the zipper.

[0046] Example 2

[0047] Unlike Embodiment 1, the zipper pull 3 in this embodiment is integrally injection molded, with rounded corners. The surface of the zipper pull 3 is coated with a hydrophobic nano-coating, preferably a silica-modified material, which reduces the adhesion between fabric fibers and the zipper. The inner surface of the guide channel 6 is coated with a Teflon coating, which reduces the friction between the inner surface of the guide channel 6 and the chain teeth 2.

[0048] The other structures are the same as in Embodiment 1, and will not be described again here.

[0049] Example 3

[0050] Unlike Embodiment 1, in this embodiment, the outer diameter of the chain tooth 2 is smaller than the outer diameter of the guide groove 6, allowing the chain tooth 2 to pass through the guide groove 6. The guide groove 6 guides the chain tooth 2 to engage. The inclined angle of the guide groove 6 is preferably 1°-5°, which helps to improve the smoothness of the zipper.

[0051] The other structures are the same as in Embodiment 1, and will not be described again here.

[0052] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
