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.

[0037] 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 modes.

[0038] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "top", "bottom", "inner", etc. 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 cannot be understood as a limitation of the present invention.

[0039] The purpose of the present invention is to provide a pull tab assembly, which can improve the stability of the pull tab after assembly to avoid loosening or shaking of the handle of the pull tab relative to the pull tab.

[0040] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , to achieve the above purpose, the present invention provides a pull tab assembly, including a pull tab 100 and a pull tab 200.

[0041] The pull tab 100 is provided with a first mounting hole 110 and a first protrusion 120 located in the first mounting hole 110. The first mounting hole 110 is a through hole penetrating the thickness direction of the pull tab 100. The projection of the first protrusion 120 on the horizontal plane is located in the first mounting hole 110. Usually, the first protrusion 120 and the pull tab 100 are of an integral structure, or the first protrusion 120 and the pull tab 100 can be separately produced according to actual needs, and then the first protrusion 120 is assembled to a specified position on the inner wall of the first mounting hole 110, which is not specifically limited here.

[0042] The pull tab 200 includes a pull tab body 210 and a first fastener 220 disposed at one end of the pull tab body 210. The first fastener 220 includes a fastener neck 221 connected to the pull tab body 210 and a fastener head 222 connected to a side of the fastener neck 221 facing away from the pull tab body 210. The pull tab body 210 can be bent relative to the fastener head 222 so that the fastener neck 221 is installed in the first mounting hole 110. A first groove 2211 adapted to the first protrusion 120 is provided on the circumferential wall of the fastener neck 221 to limit the movement of the installed first fastener 220 relative to the pull tab 100.

[0043] It should be noted that the cross-sectional dimension of the fastener neck 221 perpendicular to the extending direction of the first mounting hole 110 is smaller than the cross-sectional dimensions of the pull tab body 210 and the fastener head 222 perpendicular to the extending direction of the first mounting hole 110. After the first fastener 220 is snapped into the first mounting hole 110, the pull tab body 210 and the fastener head 222 are located on both sides of the pull tab 100, and the fastener neck 221 is located in the first mounting hole 110.

[0044] A first fastener 220 capable of being snapped into the first mounting hole 110 is provided at one end of the pull tab body 210. The first fastener 220 includes a fastener neck 221 provided with a first groove 2211 and a fastener head 222 connected to a side of the fastener neck 221 facing away from the pull tab body 210. The fastener head 222 passes through the first mounting hole 110 to guide the fastener neck 221 to be snapped into the first mounting hole 110. A first protrusion 120 is provided in the first mounting hole 110, and the fastener neck 221 is provided with a first groove 2211 adapted to the first protrusion 120. By the snap connection between the first groove 2211 and the first protrusion 120, the position of the first fastener 220 in the first mounting hole 110 is restricted, which can improve the stability of the pull tab 200 after assembly and avoid loosening or shaking of the handle of the pull tab 200 relative to the pull tab 100.

[0045] That is to say, 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 assembly, which is convenient for the installation and replacement of the pull tab 200 and the pull tab 100 during use. Through the arrangement of the first groove 2211 and the first protrusion 120, the pull tab 200 and the pull tab 100 can be relatively stable.

[0046] In this embodiment, the pull tab body 210 includes a handle portion 211 and a positioning portion 212 that are connected and can be bent relative to each other. The positioning portion 212 is used for connecting the fastener neck 221. The handle portion 211 is made of an elastic material to achieve the bending of the handle portion 211 relative to the positioning portion 212. The first fastener 220 is made of an elastic material to achieve the deformation of the first fastener 220 when it is snapped into the first mounting hole 110 and the restoration after deformation.

[0047] See also Figure 6 The assembly process of the pull tab 200 and the pull piece 100 is as follows: first bend the handle portion 211 on the pull tab body 210 so that the handle portion 211 is bent relative to the clamping portion 212 to change the angle between the clamp head 222 and the handle portion 211, and then place the clamp head 222 obliquely in the direction of the first mounting hole 110. Under the guidance of external force, one end of the clamp head 222 is passed through the first mounting hole 110. At this time, the first protrusion 120 on the first mounting hole 110 begins to enter the first groove 2211. When the first protrusion 120 completely enters the first groove 2211, press down the first clamp 220 so that the other end of the clamp head 222 completely passes through the first mounting hole 110. Then, the first clamp 220 returns to its original state, so that the pull tab 200 and the pull piece 100 are clamped and connected.

[0048] The locking portion 212 is provided with a first abutting surface 2121 and the locking head 222 is provided with a second abutting surface 2223. The first abutting surface 2121 and the second abutting surface 2223 are located on the side facing each other of the locking portion 212 and the locking head 222, so that the first abutting surface 2121 and the second abutting surface 2223 after installation abut against both sides of the pull tab 100 in the extension direction of the first installation hole 110, thereby increasing the stability of the connection between the pull tab 200 and the pull tab 100.

[0049] It is possible to consider setting the first abutting surface 2121 and the second abutting surface 2223 in parallel to keep the distance between the first abutting surface 2121 and the second abutting surface 2223 consistent. Considering that a smaller part of the pull tab body 210 may cause inconvenience to the user in pulling, it is preferred that the maximum width of the handle portion 211 and the locking portion 212 is greater than the maximum width of the first mounting hole 110.

[0050] In another embodiment, the pull tab body 210 and the first clamping member 220 are formed as one body by elastic material, and a first hole 223 is opened on the first clamping member 220, so as to reduce the material consumption and provide an avoidance space for the deformation of the first clamping member 220. The integrated structure is convenient for the mass production of the pull tab 200, and at the same time eliminates the assembly process of each component, thereby reducing the labor intensity of the staff.

[0051] The pull tab 100 further includes a second mounting hole 140 and a cross bar 150 . The cross bar 150 is disposed through the slider 300 . The second mounting hole 140 is used to accommodate a cap of the slider 300 when the cross bar 150 rotates relative to the slider 300 .

[0052] The first protrusion 120 includes a first end 121 connected to the inner wall of the first mounting hole 110 and a second end 122 away from the first end 121 . The second end 122 is a tapered structure with slopes on both sides in the extending direction of the first mounting hole 110 .

[0053] Among them, the two side surfaces of the second end 122 in the extension direction of the first mounting hole 110 can also be two planes set at an angle, for example, one side surface is set horizontally, and the other side surface is set at an angle, and the distance between the two side surfaces gradually decreases from the first end 121 to the second end 122, so that the first protrusion 120 can slide into the first groove 2211. The distance between the two side surfaces of the second end 122 in the extension direction of the cross bar 150 can also be set to gradually decrease from the first end 121 to the second end 122, so as to reduce the cross-sectional size of the second end 122.

[0054] It should be noted that the specific shapes of the four side surfaces of the second end 122 can be selected according to actual conditions, for example, they can be square, triangular, isosceles trapezoidal, etc., so that the second end 122 can be a tapered structure to facilitate the first protrusion 120 to be snapped into the first groove 2211.

[0055] The shape of the first groove 2211 should be adapted to the shape of the corresponding first protrusion 120. Considering the installation process of the first protrusion 120 being snapped into the first groove 2211, the size of the portion of the first groove 2211 contacting the second end 122 may be slightly larger than the second end 122 to provide room for the first protrusion 120 to move during the above-mentioned installation process.

[0056] In this embodiment, the clamp head 222 includes a larger third end 2221 and a smaller fourth end 2222, the distance between the third end 2221 and the clamp neck 221 is greater than the distance between the fourth end 2222 and the clamp neck 221, and the distance between the third end 2221 and the end of the pull tab body 210 away from the pull tab 100 is greater than the distance between the fourth end 2222 and the end of the pull tab body 210 away from the pull tab 100, so that after the handle portion 211 is bent relative to the locking portion 212, the gap between the clamp head 222 and the handle portion 211 is larger, which facilitates the larger end (third end 2221) of the clamp head 222 to first penetrate the first mounting hole 110, and then the smaller end (fourth end 2222) of the clamp head 222 is pressed into the first mounting hole 110.

[0057] It should be noted that after the larger third end 2221 of the clamp head 222 enters the first mounting hole 110, the first protrusion 120 and the first groove 2211 come into contact to achieve subsequent position definition. Preferably, the first groove 2211 is located on the side of the clamp neck 221 facing the third end 2221.

[0058] In addition, to facilitate the contact between the clamp head 222 and the wall of the first mounting hole 110 during installation, the side of the clamp head 222 facing away from the clamp neck 221 can be optionally set as a guiding curved surface including an inner concave arc surface and an outer convex arc surface, wherein the inner concave arc surface is located at the third end 2221 and the outer convex arc surface is located at the fourth end 2222.

[0059] See also Figure 10 In another embodiment, two first protrusions 120 are provided, and the second ends 122 of the two first protrusions 120 are arranged opposite to each other, and two first grooves 2211 are provided, and the two first grooves 2211 can be snapped into the corresponding first protrusions 120 .

[0060] It can be understood that a first groove 2211 is respectively provided on the side of the clamp neck 221 facing the third end 2221 and the side facing the fourth end 2222, and by pressing the first clamp 220, the two first grooves 2211 and the two first protrusions 120 can be snap-fitted together, which can also achieve a stable connection between the pull tab 200 and the pull piece 100.

[0061] It should be noted that there may be multiple first protrusions 120, and multiple first protrusions 120 can be distributed on the inner wall of the first mounting hole 110. It is only necessary to increase the number of first grooves 2211 at the corresponding position to achieve a stable connection between the pull tab 200 and the pull piece 100.

[0062] See also Figure 7 , Figure 8 and Figure 9 In some embodiments, the pull tab 100 is further provided with a slope 130, which is arranged opposite to the first protrusion 120 and extends obliquely to the inner wall of the first mounting hole 110. The setting of the slope 130 makes the thickness of the pull tab 100 at the slope 130 thinner. After the thickness is thinned, the inclination angle range of the card head 222 relative to the pull tab 100 can be increased when the card head 222 is obliquely installed. The slope 130 is used to provide an avoidance space for the card head 222 to pass through the first mounting hole 110, so that the installation process of the pull tab 200 is simpler and more convenient.

[0063] Among them, the first protrusion 120 is a bent structure, and the end of the bent structure away from the inner wall of the first mounting hole 110 can be set to be lower than the first mounting hole 110. It can also increase the inclination angle range of the card head 222 relative to the pull tab 100 when it is installed at an angle, thereby improving the assembly efficiency and the stability after assembly.

[0064] See also Figure 11 In other embodiments, the first mounting hole 110 can be divided into two adjacent first mounting holes 110 by a crossbeam, and two first clamping members 220 that can be respectively clamped in the two first mounting holes 110 are correspondingly provided, and the distance between the two first clamping members 220 is equal to the distance between the two first mounting holes 110, which can also achieve stability after the pull tab 200 and the pull piece 100 are connected.

[0065] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0066] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

[0067] Specific examples are used in this article to elaborate on the principles and implementation manners of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the present utility model.
