[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] In order to enable those skilled in the art in the technical field to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0035] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0036] The purpose of the present invention is to provide a pulling device for a pull head, which can avoid the limitation of the size of the pull handle when the pull loop is assembled to the pull tab, and improve the efficiency of assembling the pull loop to the pull tab.

[0037] Please refer to Figures 1 to 7 , to achieve the above object, the present invention provides a pulling device for a pull head, including a pull tab and a pull loop.

[0038] The pull tab 100 is provided with a first mounting hole 110, and the first mounting hole 110 is a through hole penetrating the thickness direction of the pull tab 100.

[0039] The pull tab 200 includes a pull handle portion 210 that can be bent relative to each other and a clamping portion 220. The clamping portion 220 includes an upper clamping member 221 connected to the pull handle portion 210 and a first clamping member 222 connected to the upper clamping member 221 and capable of being clamped in the first mounting hole 110. The first clamping member 222 includes a guiding portion on a side facing away from the upper clamping member 221. The guiding portion is provided with a guiding surface 223, and the guiding surface 223 extends to the edge of the guiding portion.

[0040] The clamping portion 220 includes an upper clamping member 221 and a first clamping member 222 connected to each other. The pull handle portion 210 and the clamping portion 220 can be bent relative to each other to provide a space for the first clamping member 222 to be inclined and inserted into the first mounting hole 110. The guiding portion on the side of the first clamping member 222 facing away from the upper clamping member 221 is provided with a guiding surface 223 through the guiding portion, and the guiding surface 223 extends to the edge of the guiding portion, so that the bottom of the first clamping member 222 and the inner wall of the first mounting hole 110 are in smooth contact. The pull handle portion 210 of the pull tab 200 can achieve stable connection between the pull tab 100 and the pull tab 200 without passing through the first mounting hole 110, which can avoid the size limitation of the pull handle when the pull tab 200 is assembled to the pull tab 100. At the same time, the efficiency of assembling the pull tab 200 to the pull tab 100 can be improved through the setting of the guiding surface 223.

[0041] Please refer to Figure 8 , the assembly process of the pull tab 200 and the pull tab 100 is as follows: first, bend the pull handle portion 210 of the pull tab 200 so that the pull handle portion 210 bends relative to the clamping portion 220, and then the pull handle portion 210 bends relative to the first clamping member 222. After that, place the first clamping member 222 in an inclined direction with respect to the first mounting hole 110, and guide one end of the first clamping member 222 to pass through the first mounting hole 110 under the action of an external force. Then, press the other end of the first clamping member 222 so that the first clamping member 222 is clamped in the first mounting hole 110 to complete the clamping connection between the pull tab 200 and the pull tab 100.

[0042] The pull tab 200 and the pull tab 100 are of a split structure. The pull tab 200 can be assembled at a specified position of the pull tab 100 in the above manner to form a pull tab 100 assembly, which is convenient for the installation and replacement of the pull tab 200 and the pull tab 100 during use. Through the setting of the guiding surface 223 and the relief groove 224, the pull tab 200 and the pull tab 100 can be relatively stable.

[0043] Among them, a relief groove 224 extending to the guiding surface 223 is provided inside the first clamping member 222. The relief groove 224 is used to provide a deformation space for the first clamping member 222 during the process of being clamped in the first mounting hole 110. Through the relief groove 224, a certain amount of deformation can be provided during assembly for convenient assembly, and at the same time, the injection volume of the first clamping member 222 can be reduced, avoiding surface shrinkage depression caused by too thick injection plastic and shrinkage.

[0044] In this embodiment, the pulling part 210 includes a first end connected to the upper clamping part 221 and a second end 212 facing away from the first end. The pulling part 210 and the upper clamping part 221 are tapered at the first end to form a bending part 213, and the bending part 213 is made of an elastic material.

[0045] It can be understood that the pulling part 210 and the upper clamping part 221 can be connected as an integral structure. By providing a bending part 213 made of an elastic material at the connection between the pulling part 210 and the upper clamping part 221, the pulling part 210 and the upper clamping part 221 can be bent relative to each other to provide the space required when the first clamping part 222 is inserted obliquely in the direction of the first mounting hole 110 during the above installation process, avoiding the installation difficulties caused by excessive contact between the pulling part 210 and the pulling tab 100 during the installation of the first clamping part 222 into the first mounting hole 110.

[0046] In addition, the pull loop 200 can be of an integral structure, that is, the pulling part 210, the upper clamping part 221, and the first clamping part 222 are connected as a whole. The integral structure of the pull loop 200 can eliminate the assembly steps between the pulling part 210, the upper clamping part 221, and the first clamping part 222, reducing the labor intensity of the staff. At the same time, the integral structure of the pull loop 200 is convenient for mass production of the pull loop 200 and reduces the labor intensity of the staff.

[0047] The entire pull loop 200 can be made of an elastic material and processed by an injection molding process. The specific material of the pull loop 200 can also be selected according to actual needs, as long as it has the above-mentioned elastic deformation and recovery ability.

[0048] In this embodiment, the pulling tab 100 further includes a second mounting hole 120 and a cross bar 130. The cross bar 130 passes through the pull head 300, and the second mounting hole 120 is used to accommodate the cap of the pull head 300 when the cross bar 130 rotates relative to the pull head 300, so that the pulling tab 100 and the pull loop 200 mounted on the pulling tab 100 can rotate around the axis of the cross bar 130 to the front end and the rear end of the pull head 300. The pulling tab 100 can be a conventional pulling tab 100.

[0049] It should be noted that considering the feel when pulling the pulling part 210 of the pull loop 200, the width of the pulling part 210 in the extending direction of the cross bar 130 can be appropriately widened. In this embodiment, it is preferably that the maximum width of the pulling part 210 in the extending direction of the cross bar 130 is greater than the maximum width of the first mounting hole 110 in the extending direction of the cross bar 130. Among them, the maximum width of the first mounting hole 110 (the distance between the two farthest points on the inner wall of the first mounting hole 110) is usually the maximum width of the first mounting hole 110 in the extending direction of the cross bar 130.

[0050] Among them, the pulling part 210 is further provided with a first protrusion 214. The first protrusion 214 and the first clamping member 222 are arranged on the same side of the pulling part 210. The first protrusion 214 includes an inclined surface 215 facing away from the pulling part 210, and the distance between the inclined surface 215 and the pulling part 210 decreases along the direction from the second end 212 to the first end, so as to prevent the phenomenon that the pulling part 210 is prone to slipping when the thickness of the pulling part 210 is uniform.

[0051] The first protrusion 214 can adopt a U-shaped structure. The U-shaped first protrusion 214 includes a bottom and two side parts. One side of the bottom and the side parts is attached to the pulling part 210, and the other side of the two side parts includes the above-mentioned inclined surface 215. The distance between the inclined surface 215 and the pulling part 210 is less than the distance between the side of the bottom facing away from the pulling part 210 and the pulling part 210, so as to achieve the anti-slip function.

[0052] In this embodiment, the first clamping member 222 includes a lower clamping member 2221 and a clamping neck 2222 located between the lower clamping member 2221 and the upper clamping member 221. The size of the clamping neck 2222 is smaller than the sizes of the lower clamping member 2221 and the upper clamping member 221. When the first clamping member 222 is clamped to the pull tab 100, the clamping neck 2222 is located in the first mounting hole 110, and the lower clamping member 2221 and the upper clamping member 221 are respectively located on both sides of the pull tab 100. At the same time, the sizes of the lower clamping member 2221 and the upper clamping member 221 are larger than the size of the first mounting hole 110, so that the pull loop 200 and the pull tab 100 are stably connected.

[0053] The lower clamping member 2221 includes a thicker third end 2223 and a thinner fourth end 2224. The thickness of the third end 2223 in the extending direction of the first mounting hole 110 is greater than the thickness of the fourth end 2224 in the extending direction of the first mounting hole 110. The thicker third end 2223 first penetrates through the first mounting hole 110, and then an external force presses the thinner fourth end 2224, so that the lower clamping member 2221 penetrates from one side of the first mounting hole 110 to the other side. The thicker third end 2223 can play a better abutting role to keep the pull loop 200 and the pull tab 100 stably connected. The thinner fourth end 2224 is convenient for pressing in the lower clamping member 2221, improving the assembly efficiency of the pull tab 100 and the pull loop 200.

[0054] Wherein, the distance between the third end 2223 and the clamping neck 2222 is greater than the distance between the fourth end 2224 and the clamping neck 2222, and the distance between the third end 2223 and the second end 212 is greater than the distance between the fourth end 2224 and the second end 212. The second end 212 of the pulling part 210 and the third end 2223 of the lower clamping part 2221 are arranged on the same side relative to the clamping neck 2222, so that when the pulling part 210 is bent relative to the lower clamping part 2221, a clearance space can be provided for the third end 2223, which has a better abutting effect and is thicker, to be inserted into the first mounting hole 110.

[0055] It should be noted that the guiding surface 223 can reduce the friction during the installation of the first clamping member 222 into the first mounting hole 110. The guiding surface 223 includes a concave arc surface 2231, a convex arc surface 2232 and two side arc surfaces 2233. The concave arc surface 2231 is located between the relief groove 224 and the third end 2223, the convex arc surface 2232 is located between the relief groove 224 and the fourth end 2224, and the two side arc surfaces 2233 are respectively located on both sides of the relief groove 224 and connected to the concave arc surface 2231 and the convex arc surface 2232. The two side arc surfaces 2233 can adopt a flared structure, so that it is easy for the guiding part to slide into the first mounting hole 110 after contacting the flared outer edge of the first mounting hole 110. Through the design of the convex arc surface 2232, it can be realized by thinning near the fourth end 2224, which can also achieve the purpose of facilitating the deformation of the fourth end 2224 and saving injection molding materials.

[0056] In this embodiment, the upper clamping part 221 is provided with a first plane 225, and the lower clamping part 2221 is provided with a second plane 2225. The first plane 225 and the second plane 2225 are located on the opposite sides of the upper clamping part 221 and the lower clamping part 2221, and both the first plane 225 and the second plane 2225 can abut against the pull tab 100, increasing the connection stability between the pull loop 200 and the pull tab 100.

[0057] The first plane 225 and the second plane 2225 can be arranged in parallel so that the distance between the first plane 225 and the second plane 2225 remains consistent, and the distance between the first plane 225 and the second plane 2225 is greater than or equal to the thickness of the pull tab 100 in the extending direction of the first mounting hole 110, which is used to maintain the clamping stability between the pull tab 100 and the clamping part 220.

[0058] The give-way groove 224 is located in the middle part of the first clamping member 222 in the extension direction of the following cross bar 130, and the axis of the give-way groove 224 is perpendicular to the first plane 225, so that the first clamping member 222 can adopt a symmetrical structure. The distance between the end of the upper clamping member 221 away from the handle portion 210 and the axis of the give-way groove 224 is greater than the distance between the fourth end 2224 and the axis of the give-way groove 224, which can increase the abutment effect between the end of the upper clamping member 221 away from the handle portion 210 and the pull tab 100.

[0059] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0060] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0061] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the utility model.
