[0041] Embodiment one

[0042] Please refer to Figures 1 to 8 The present application is a three-dimensional brush-shaped pull tab structure, which comprises a pull body 1, wherein the pull body 1 specifically refers to a component for the user to grab with his hand and drive the pull head 100 to slide during use of the zipper; the pull body 1 comprises a grab part 11 and a connecting part 12 for connecting the pull head 100;

[0043] The surface of the grab part 11 is provided with a coating contour area 111, and the coating contour area 111 is provided with an adhesive coating 2; wherein the coating contour area 111 can be set according to the actual required shape and position, and is not specific to a certain specific shape, such as rectangle, triangle, circle, ellipse, irregular polygon and the like; the adhesive coating 2 can be positioned and set according to the specific shape of the coating contour area 111, and the adhesive coating 2 is used to achieve the adhesion effect;

[0044] A plurality of elastic columns 3 are arranged at intervals on the adhesive coating 2, and each elastic column 3 is perpendicular to the adhesive coating 2 and forms a brush-like structure.

[0045] The present application adopts the technology of setting a coating profile area 111 on the surface of the gripping part 11 of the pulling body 1, setting an adhesive coating 2 in the coating profile area 111, and setting a plurality of elastic columns 3 perpendicular to the adhesive coating 2 on the adhesive coating 2, so as to form a three-dimensional brush-like structure on the gripping part 11 of the pulling body 1. Through the above technical solution, on the one hand, the three-dimensional brush-like structure has the characteristics of novel sense and recognition, which helps to enrich the types of pull piece structure and provides users with diversified choices. At the same time, the brush-like structure formed by the elastic columns 3 has a comfortable touch when the user holds the pulling body 1 with hands, has a decompression effect, and can well improve the use experience. On the other hand, it can prevent the user from slipping when operating the pulling body 1, especially when the hands sweat in summer or wear gloves in winter, which can also prevent the fingers from slipping with the pulling body 1.

[0046] As a first specific embodiment of the present application, please refer to Figures 1-4 When the pulling body 1 is a pull tab body 1a directly connected with the puller 100, a first mounting through hole 121 penetrating from the top to the bottom is arranged on the connecting part 12 of the pull tab body 1a, so as to realize the assembly of the pull tab body 1a and the puller 100 by using the first mounting through hole 121. Of course, the above is only a preferred embodiment of the connecting part 12 of the present application connected with the puller 100, but the present application is not limited to this, and other structures of the connecting part 12 can also be used to realize the connection with the puller 100 in specific implementation.

[0047] As a second specific embodiment of the present application, the pulling body 1 is a pull handle body 1b directly connected with the puller 100. When the pulling body 1 is a pull handle body 1b directly connected with the puller 100, the connecting part 12 of the pull handle body 1b can adopt a pull rope, and the pull rope is directly connected with the puller 100. Of course, the above is only a preferred embodiment of the connecting part 12 of the present application connected with the puller 100, but the present application is not limited to this, and other structures of the connecting part 12 can also be used to realize the connection with the puller 100 in specific implementation.

[0048] As a third specific embodiment of the present application, please refer to Figures 5-8As shown, the pull holding body 1 is a pull tab body 1a connected with a pull loop body 1b, and the pull tab body 1a is connected with the puller 100. When the pull holding body 1 is a pull tab body 1a connected with a pull loop body 1b, one end of the pull tab body 1a can be provided with a first mounting through hole 121 penetrating from the top to the bottom, so as to realize the assembly of the pull tab body 1a and the puller 100 by using the first mounting through hole 121. Of course, the above is only one preferred embodiment of the connection between the pull tab body 1a and the puller 100 of the present application, but the present application is not limited to this. In the specific implementation, the pull tab body 1a can also be connected with the puller 100 by using other structures. One end of the pull tab body 1a can be provided with a second mounting through hole 122 penetrating from the top to the bottom, and the pull loop body 1b can be a long strip-shaped material with both ends open, but the long strip-shaped material is folded in half and an annular part is made in the middle, which is the connecting part 12 of the pull loop body 1b, and the connecting part 12 of the pull loop body 1b is assembled on the second mounting through hole 122 of the pull tab body 1a. Of course, the above is only one preferred embodiment of the connection between the pull loop body 1b and the pull tab body 1a of the present application, but the present application is not limited to this. In the specific implementation, the pull loop body 1b and the pull tab body 1a can also be connected by using other structures. The pull loop body 1b can also adopt various existing pull loop structures, for example, the connecting part 12 of the pull loop body 1b can adopt a pull rope, and the pull rope can be connected with the pull tab body 1a.

[0049] In some embodiments of the present application, the adhesive coating 2 is stacked layer by layer to the required height by the silica gel dot array 4 to obtain each of the elastic columns 3. In the embodiments of the present application, since the elastic columns 3 are obtained by stacking layer by layer the silica gel dot array 4, the elastic columns 3 are in a cylindrical structure as a whole. Of course, the above is only one preferred embodiment of the present application, but the present application is not limited to this. In the specific implementation, other shapes of silica gel dot arrays can also be used, such as an elliptical silica gel dot array. In the specific implementation of the present application, the silica gel dot array 4 can be automatically stacked by using an automatic silica gel stacking device, which not only realizes more accurate positioning, but also improves production efficiency and reduces cost.

[0050] Furthermore, the silicone dot array 4 includes several neatly arranged columns of liquid silicone dots 41. The circular diameter of each liquid silicone dot 41 is 0.3-1 mm. For example, the circular diameter of each liquid silicone dot 41 can be any one of 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, and 1 mm. Of course, the above is only a preferred embodiment of the present invention, but the present invention is not limited thereto. In specific implementations, the circular diameter of each liquid silicone dot 41 can be adjusted according to actual needs. In the silicone dot array 4 of the present invention, the specific number of columns of liquid silicone dots 41 can be set according to the size of the coating contour area 111, and the number of liquid silicone dots 41 in each column can also be set as needed. Meanwhile, when the diameter of a single liquid silicone dot 41 is too small, it will be difficult to accurately perform the stacking operation; while when the diameter of a single liquid silicone dot 41 is too large, it will be difficult to set a sufficient number of elastic pillars 3 within the coating contour area 111 of the holding body 1, which will affect the actual use effect. The present invention designs the diameter of a single liquid silicone dot 41 to be 0.3-1mm, which facilitates the accurate stacking of the silicone dot array 4 and ensures that a sufficient number of elastic pillars 3 can be set within the limited coating contour area 111 to improve the use effect.

[0051] Furthermore, the thickness of the single-layer silicone dot array 4 is 0.15-0.3mm. For example, the thickness of the single-layer silicone dot array 4 can be set to any one of 0.15mm, 0.18mm, 0.21mm, 0.25mm, 0.28mm, and 0.3mm. The overall height of the elastic column 3 is 1-8mm. For example, the overall height of the elastic column 3 can be set to any one of 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, and 8mm. Of course, the above is only a preferred embodiment of the present invention, but the present invention is not limited to this. In specific implementation, the thickness of the single-layer silicone dot array 4 and the overall height of the elastic column 3 can be adjusted according to actual needs. In practical implementation, if the thickness of the single-layer silicone dot array 4 is too thin or too thick, it will affect the stacking of the silicone dot array 4. At the same time, if the overall height of the elastic column 3 is too low, it will not be able to form a brush-like structure intuitively, resulting in poor sensory perception and tactile feel. If the overall height of the elastic column 3 is too high, it will be inconvenient for users to grasp, and the tactile feel will also be poor. This invention designs the thickness of the single-layer silicone dot array 4 to be 0.15-0.3mm and the overall height of the elastic column 3 to be 1-8mm. This not only facilitates the stacking and curing of the silicone dot array 4 but also ensures a good tactile feel and improves sensory perception.

[0052] In some embodiments of the present application, the pulling body 1 is a sheet-shaped body to facilitate the user to grasp. Of course, the above is only a preferred embodiment of the present application, but the present application is not limited to this. In the actual implementation, other forms of the pulling body 1 can also be used. In the actual implementation of the present application, a coating contour area 111 can be coated on the upper surface and / or the lower surface of the grasping portion 11 of the pulling body 1, and an adhesive coating 2 and an elastic column 3 can be arranged on the upper surface and / or the lower surface of the grasping portion 11. At the same time, the coating contour area 111 can be a lower concave area, an upper convex area formed on the upper surface and / or the lower surface of the grasping portion 11, or a flat area with the upper surface and / or the lower surface of the grasping portion 11.

[0053] The pulling body 1 can be made of a woven tape material, a textile belt-shaped material, a metal material, or an injection molding material. In the actual implementation of the present application, the material of the pulling body 1 can be set according to the actual use needs. For example, when the pulling body 1 is a pull tab body 1a directly connected with the puller 100, the pull tab body 1a can be made of a metal material (such as zinc alloy, copper, iron, etc.), or an injection molding material. For another example, when the pulling body 1 is a pull handle body 1b connected with the pull tab body 1a, the pull tab body 1a can be made of a metal material or an injection molding material, and the pull handle body 1b can be made of a woven tape material or a textile belt-shaped material, etc.

[0054] In some embodiments of the present application, the adhesive coating 2 is a resin adhesive coating, and the thickness of the adhesive coating 2 is 0.2-0.5 mm. For example, the thickness of the adhesive coating 2 can be set to any one of 0.2 mm, 0.3 mm, 0.4 mm, and 0.5 mm. Of course, the above is only a preferred embodiment of the present application, but the present application is not limited to this. In the actual implementation, the type of the glue used by the adhesive coating 2 and the thickness of the adhesive coating 2 can be adjusted according to the actual needs. In the actual implementation, the surface adhesion of the grasping portion 11 of the pulling body 1 is very poor. If the elastic column 3 is directly arranged on the surface of the grasping portion 11, the elastic column 3 can easily be separated from the surface of the grasping portion 11. In the present application, the coating contour area 111 is arranged on the surface of the grasping portion 11, and a certain thickness of resin glue is sprayed in the coating contour area 111 to form the adhesive coating 2, and then the elastic column 3 is arranged on the surface of the adhesive coating 2. In this way, each elastic column 3 can be integrated with the adhesive coating 2, and the contact area between the adhesive coating 2 and the surface of the grasping portion 11 is large. Therefore, the elastic column 3 and the grasping portion 11 of the pulling body 1 can be reliably adhered together, and it is ensured that the elastic column 3 will not be separated during use.

[0056] Referring to Figures 1 to 8 The present application is a zipper, which comprises a pair of zipper chains (not shown) with teeth, a slider 100 and a three-dimensional brush-like puller structure. The slider 100 is installed between the pair of zipper chains to open or close the teeth of the zipper chains by sliding the slider 100. The three-dimensional brush-like puller structure is installed on the slider 100 to drive the slider 100 to slide. The specific structure of the three-dimensional brush-like puller structure and the technical effects achieved thereby will be described in detail in Embodiment One, which will not be repeated here.

[0057] Embodiment Three

[0058] Referring to Figures 1 to 8 The present application is a manufacturing method of a three-dimensional brush-like puller structure. The specific structure of the three-dimensional brush-like puller structure and the technical effects achieved thereby will be described in detail in Embodiment One, which will not be repeated here.

[0059] The manufacturing method comprises the following steps:

[0060] Step S1: According to the required shape and position, a coating contour area 111 is positioned on the surface of the gripping portion 11 of the holding body 1. The coating contour area 111 is not specific to a certain specific shape, such as a rectangle, a triangle, a circle, an ellipse, an irregular polygon, etc.

[0061] Step S2: Adhesive is sprayed in the coating contour area 111, and after the adhesive is adhered and solidified with the surface of the gripping portion 11, an adhesive coating 2 is formed. The thickness of the adhesive coating 2 is 0.2-0.5mm. The adhesive can be a resin adhesive, and other types of adhesive can also be used as long as it can reliably bond the elastic column 3 with the surface of the gripping portion 11.

[0062] Step S3: The silica gel dot array 4 is laminated onto the surface of the adhesive coating 2, so that the silica gel dot array 4 is adhered and solidified with the surface of the adhesive coating 2, ensuring that the laminated silica gel dot array 4 will not fall off.

[0063] Step S4, continue to stack the silica gel dot array 4 on the cured silica gel dot array 4, and stack and cure for multiple times until the desired height is reached, so as to obtain a plurality of elastic columns 3 in a brush-like structure. In the specific implementation of the present application, the output of the automatic silica gel stacking device is a liquid silica gel dot array 4, so for each layer of silica gel dot array 4 to be stacked, it is necessary to continue to stack the next layer of silica gel dot array 4 after heating and curing until the desired height is reached. In the present application, in order to form a brush-like structure with better sensory and more comfortable touch, the silica gel dot array 4 includes a plurality of rows of liquid silica gel dots 41 arranged in an orderly manner, the circular diameter of a single liquid silica gel dot 41 is 0.3-1mm, the thickness of a single layer of silica gel dot array 4 is 0.15-0.3mm, and the overall height of the elastic column 3 is 1-8mm.

[0064] As a specific embodiment of the present application, the adhesive coating 2 and the silica gel dot array 4 are cured by UV light heating. That is, in the specific implementation of the present application, after the adhesive is sprayed in the coating profile area 111, the sprayed adhesive is heated and cured by UV light heating, thereby forming the adhesive coating 2. At the same time, after each layer of silica gel dot array 4 is stacked, the stacked silica gel dot array 4 is also heated and cured by UV light heating, so that the adhesive coating 2 and the silica gel dot array 4, as well as the adjacent two layers of silica gel dot array 4, can be reliably bonded and fixed together.

[0065] Although the specific embodiments of the present application are described above, those skilled in the art should understand that the specific examples described are only illustrative and are not intended to limit the scope of the present application, and equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present application should be covered within the scope of the claims of the present application.
