Description

Technical Field

[0001] This utility model relates to the field of slip chains, and in particular to a slip-resistant zipper. Background Technology

[0002] In existing clothing designs, zippers are a common opening and closing mechanism, widely used in everyday clothing and special protective suits. However, traditional zippers usually require users to manually operate the slider to open or close them. In certain special application scenarios, manual operation of zippers presents many inconveniences, including but not limited to: difficulty in operation when hands are restricted, and low efficiency during operation.

[0003] A safety slip chain with application number CN201410658506.1 is available on the Chinese patent website. The safety slip chain includes an upper chain body and a lower chain body. The upper chain body includes multiple clamping rings mounted on a base fabric. Each clamping ring includes two integrally connected arc-shaped clamping arms. The lower chain body includes an elongated groove and a base fabric connecting seat at the lower end of the groove. The base fabric connecting seat is connected to the base fabric. The upper chain body is clamped onto the groove and connected to the lower chain body via the clamping rings. This safety slip chain can be installed on outdoor clothing or sun-protective clothing, allowing the hood to rotate left and right on the groove to a certain extent by turning the head. This prevents difficulty in adjusting the hood when hands are restricted and reduces the probability of accidents caused by the hood obstructing vision.

[0004] However, in actual use, the upper chain body is prone to partially slipping off from the lower chain body, and it is easy to get stuck during reinstallation, making operation inconvenient. Utility Model Content

[0005] In view of this, the present invention provides an anti-slip zipper to solve the above problems.

[0006] A non-slip zipper includes an upper chain body, a lower chain body fitted over the upper chain body, at least two end caps fitted at both ends of the lower chain body, and at least one segmented end cap disposed within the lower chain body. The upper chain body includes multiple sliders, multiple base mounting seats connecting the sliders, and an upper base fabric connecting the base mounting seats. Each slider has a connecting hole at its center. A connecting cord is disposed in the connecting holes of different sliders. The connecting cord passes through the connecting holes of the multiple sliders, connecting the multiple sliders in a linear fashion to form the upper chain body. The base mounting seats slide on the lower chain body via the sliders, causing the upper base fabric to move. The lower chain body includes multiple clamping portions, multiple second mounting seats connecting the clamping portions, and a lower base fabric connecting the second mounting seats. The multiple clamping portions are evenly arranged on the lower base fabric. The multiple clamping portions are segmented, with segmented end caps disposed at the segmentation points. The sliders are disposed within the clamping portions and slide within them.

[0007] Furthermore, the slider is shaped like a cylinder with an oblong cross-section.

[0008] Furthermore, the slider has rounded corners and no sharp corners.

[0009] Furthermore, the base mounting base includes a mounting piece connected to the slider, and a mounting seat disposed on the mounting piece. The mounting seat is provided with a mounting groove connected to the upper base fabric, and the mounting piece moves with the slider at the opening of the clamping part.

[0010] Furthermore, the second mounting base is provided with a mounting groove for connection with the lower base fabric.

[0011] Furthermore, the plug includes a handle, a rod connecting the handle, and a snap ring disposed at the end of the rod. The rod is hollow and has two opposing deformation grooves on its surface. The rod is sleeved inside the clamping part, and the snap ring is engaged between two adjacent clamping parts. At the same time, the rod is engaged with the clamping part by the handle and the snap ring.

[0012] Furthermore, the clamping part has a cross-sectional shape that is an open annulus.

[0013] Compared with existing technologies, this utility model provides an anti-slip zipper with end caps at both ends of the lower zipper body and segmented end caps at its segmentation points to prevent the upper zipper body from slipping off the lower zipper body during sliding. A connecting cord passes through different connecting holes to connect to the upper zipper body. The connecting cord guides the slider, preventing it from getting stuck in the gaps of the lower zipper body, making operation more convenient. Attached Figure Description

[0021] Please see Figures 1 to 5 This is a structural schematic diagram of an anti-slip zipper provided by this utility model. The anti-slip zipper includes an upper chain body 10, a lower chain body 20 sleeved on the upper chain body 10, at least two end caps 30 sleeved on the lower chain body 20, and at least one segmented end cap 40 sleeved on the lower chain body 20.

[0022] The upper chain body 10 includes multiple sliders 11, multiple base mounting seats 12 connecting the sliders 11, and an upper base fabric 13 connecting the base mounting seats 12. Each slider 11 has a connecting hole 111 at its center. A connecting rope 112 is provided in each of the connecting holes 111 of different sliders 11. The connecting rope 112 passes through the connecting holes 111 of the multiple sliders 11, thereby connecting the multiple sliders 11 in a linear fashion to form the upper chain body 10. When the upper chain body 10 slides in the lower chain body 20, the connecting rope 112 guides the sliders 11. When a slider 11 is engaged in a gap in the lower chain body 20, adjacent sliders 11 provide additional pulling force in different directions, pulling out the engaged slider 11. The slider 11 is a cylinder with an elongated oval cross-section and rounded corners to reduce the contact area between the slider 11 and the lower chain 20 during sliding, and it has no sharp corners, making the upper chain 10 slide more smoothly. The slider 11 is made of plastic.

[0023] The base mounting seat 12 includes a mounting plate 121 connected to the slider 11, and a mounting base 122 disposed on the mounting plate 121. The base mounting seat 12 slides on the lower chain body 20 via the slider 11, driving the upper base fabric 13 to move. The base mounting seat 12 and the upper base fabric 13 are integrally formed. The mounting base 122 is provided with a mounting groove and is heat-fused to the upper base fabric 13. The base mounting seat 12 is made of plastic.

[0024] The lower chain body 20 includes multiple clamping parts 21, multiple second mounting seats 22 connected to the clamping parts 21, and a lower base fabric 23 connected to the second mounting seats 22. The clamping parts 21 are evenly arranged on the lower base fabric 23, and are segmented, with segment plugs 40 at each segment to prevent interference between different upper chain bodies 10 located on the clamping parts 21 during movement. End plugs 30 are provided at both ends of the lower chain body 20 to prevent the upper chain bodies 10 from slipping. Different upper chain bodies 10 are mounted on different segments of the lower chain body 20. The clamping parts 21 have an open annular cross-section. The inner diameter of the clamping part 21 is larger than the maximum length of the slider 11, allowing the slider 11 to be positioned within and slide inside the clamping part 21. The mounting piece 121 moves with the slider 11 at the opening of the clamping part 21, allowing the upper base fabric 13 to move on the lower chain body 20. The second mounting base 22 has a mounting groove and is thermally fused to the lower base fabric 23. The lower chain body 20 is made of plastic.

[0025] The end caps 30 are used to prevent the upper chain body 10 from slipping off from both ends of the lower chain body 20 during sliding. Each end cap 30 includes a handle 31, a rod 32 connecting the handle 31, and a locking ring 33 at the end of the rod 32. The rod 32 is hollow and has two opposing deformation grooves 34 on its surface. The rod 32 is inserted into the inside of the clamping part 21, and the locking ring 33 engages between two adjacent clamping parts 21. Simultaneously, the rod 32 is engaged with the clamping part 21 by the handle 31 and the locking ring 33, thereby fixing the end caps 30. The end caps 30 are made of plastic.

[0026] The segmented plug 40 is used to prevent the upper zipper 10 from slipping off the segment of the lower zipper 20. The segmented plug 40 is made of plastic.

[0027] When in use, such as when installed on sun-protective clothing, the upper base fabric 13 is sewn to the hood, so that the upper chain body 10 wraps around the lower end of the hood, and the lower chain body 20 is sewn to the neckline of the sun-protective clothing, so that the lower chain body 20 is positioned at the neckline. When the wearer turns their head, the hood turns with the head. Because the upper chain body 10 is blocked by the end caps 30 and the segmented caps 40, it will not slip off from the sides and segments of the lower chain body 20, thus preventing the hood from slipping off the sun-protective clothing due to repeated head rotations. The upper chain body 10 is pulled by the connecting cord 112, making the sliding of the upper chain body 10 smoother.

[0028] Compared with the prior art, the anti-slip zipper provided by this utility model has end caps 30 at both ends of the lower chain body 20 and segmented end caps 40 at its segmentation points to prevent the upper chain body 10 from slipping off the lower chain body 20 during sliding. A connecting rope 112 passes through different connecting holes 111 to connect the upper chain body 10. The connecting rope 112 guides the slider 11, preventing the slider 11 from getting stuck in the gaps of the lower chain body 20, making operation more convenient.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
