Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of zipper accessories, and particularly relates to a zipper puller. BACKGROUND

[0002] In order to better adjust the front and back positions of the movable seat, a slide rail assembly matched with the seat is arranged on the bottom plate. The slide rail assembly can include an upper slide rail and a lower slide rail, the lower slide rail is fixedly connected to the floor, and the upper slide rail is connected to the seat, so that the seat can be moved forward and backward smoothly through the lower slide rail and the upper slide rail which are matched with each other. However, due to the long strip-shaped opening of the lower slide rail, foreign matters are likely to fall into the lower slide rail through the opening, which not only makes it difficult to clean the foreign matters falling into the lower slide rail, but also seriously affects the movement of the upper slide rail and the seat.

[0003] In order to solve the problem of foreign matters falling into the lower slide rail, a zipper structure is covered on the lower slide rail, and a zipper slider is connected to the seat. The zipper slider is rotationally matched with the zipper puller through a screw, and the zipper slider can slide with the zipper puller when the seat moves, so as to realize the meshing or separation of the two groups of zipper racks. In this way, the zipper racks outside the coverage range of the seat are always in the meshing state, which effectively prevents various foreign matters from entering the lower rail and ensures the normal use of the slide rail.

[0004] However, in the above-mentioned manner, the zipper slider and the zipper puller are rotationally matched through a screw, so that the zipper puller can swing to a large extent, which may cause the zipper puller to swing and deviate when subjected to unbalanced force, resulting in unstable connection. In addition, the zipper puller and the zipper slider are not convenient to disassemble and assemble. CONTENT OF THE UTILITY MODEL

[0005] The purpose of the embodiment of the application is to provide a zipper puller which can solve the problems of unstable connection of the zipper puller and inconvenient disassembly and assembly.

[0006] In order to solve the above technical problems, the application is implemented as follows:

[0007] The embodiment of the application provides a zipper puller, which comprises a zipper puller body, a puller handle and a force receiving member.

[0008] The zipper puller body has a chain tooth channel for passing chain teeth, the chain tooth channel extends in the front-rear direction of the zipper puller, and the zipper puller body has an upper side wall above the chain tooth channel.

[0009] The puller handle has a zipper puller connecting end and a force receiving connecting end, the zipper puller connecting end is fixedly connected to the upper side wall, the force receiving member is located in front of the upper side wall, and the force receiving connecting end extends out of the zipper puller body in a direction away from the upper side wall in the front-rear direction and the up-down direction and is fixedly connected to the force receiving member.

[0010] The force receiving member has a front force receiving surface for receiving a force from the front and a rear force receiving surface for receiving a force from the rear, and the front and rear force receiving surfaces extend beyond the pull handle in the left-right direction of the puller.

[0011] In the embodiment of the present application, the puller body is used to cooperate with the teeth, so that the teeth can be combined or separated during the reciprocating movement of the puller body; the force receiving member receives the force from the front through the front force receiving surface and receives the force from the rear through the rear force receiving surface, and the pull handle is used to transmit the external force received by the force receiving member to the puller body, so that the puller body can move. Based on the above structure, when the puller is used to cooperate with the zipper traction seat, the pull handle and the force receiving member can be matched with the zipper traction seat respectively, so as to ensure the reliability of the cooperation between the puller and the zipper traction seat. Compared with the cooperation mode of the zipper head and the zipper slider in the related art, the cooperation between the puller and the zipper traction seat in the embodiment of the present application can prevent the puller from rotating relative to the zipper traction seat during the reciprocating movement, thereby improving the overall stability of the puller, preventing the puller from swinging and deviating, and facilitating the disassembly and assembly of the puller and the zipper traction seat.

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0027] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually a class, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0028] The embodiments of the present application will be described in detail below with reference to the drawings and specific examples and their application scenarios.

[0029] Reference Figures 1 to 5 The embodiments of the present application disclose a puller 01 for cooperating with a zipper traction seat 02 to realize the bearing and fixing of the puller 01 through the zipper traction seat 02, so as to ensure the stability of the puller 01. The disclosed puller 01 comprises a puller body 10, a pull handle 20 and a force receiving member 30, referring to Figures 1 to 3 .

[0030] The puller body 10 is a basic component, which can provide a bearing basis for the pull handle 20 and the force receiving member 30, etc. Of course, the puller body 10 can also be used to cooperate with the teeth of the zipper, so as to realize the combination or separation of the teeth through the reciprocating movement of the puller body 10.

[0031] In some embodiments, the puller body 10 has a slider channel M for passing the slider through the slider channel M, which extends in the front-rear direction of the puller 01; and the puller body 10 has an upper side wall 11 above the slider channel M to facilitate the connection of the pull handle 20.

[0032] Exemplarily, the slider channel M can be a Y-shaped slider channel M, specifically, the slider channel M can have two channels at the front end in the front-rear direction, and one channel at the rear end, through which two strip sliders of the zipper can be respectively inserted; as the puller 01 moves forward, the two strip sliders are embedded together under the extrusion of the channel at the rear end, thereby realizing the combination of the strip sliders; conversely, as the puller 01 moves backward, the combined two strip sliders can be separated by the part between the two channels at the front end, and the two strip sliders can move along the two channels at the front end respectively, thereby realizing the separation of the strip sliders.

[0033] The pull handle 20 is a force transmission member, which can transmit the force borne by the force receiving member 30 to the puller body 10, so that the puller body 10 can reciprocate. The pull handle 20 has a puller connecting end 211 and a force receiving connecting end 222, and the puller connecting end 211 is fixedly connected to the upper side wall 11, so that the pull handle 20 is fixedly connected to the puller body 10.

[0034] Optionally, the puller connecting end 211 and the upper side wall 11 can be fixedly connected by welding, bonding, riveting, clamping or the like, and the puller 01 can also be integrally formed by injection molding. In addition, the connection between the puller connecting end 211 and the upper side wall 11 can also be provided with a chamfer or a circular arc, which can not only alleviate the stress concentration problem, but also facilitate the disassembly of the puller 01 and the zipper traction seat 02.

[0035] The force receiving connecting end 222 extends out of the puller body 10 in the front-rear direction and the up-down direction of the puller 01 away from the upper side wall 11, and the force receiving member 30 is fixedly connected to the force receiving connecting end 222. Based on this arrangement, when the force receiving member 30 bears the force, the force can be transmitted to the puller body 10 through the pull handle 20, so that the puller body 10 reciprocates in the front-rear direction; the force receiving connecting end 222 of the pull handle 20 and the force receiving member 30 both extend out of the front end of the puller body 10, so that the pull handle 20 and the force receiving member 30 can cooperate with the zipper traction seat 02. Optionally, the force receiving member 30 and the force receiving connecting end 222 can be fixedly connected by welding, bonding, riveting, clamping or the like, or can be integrally formed.

[0036] In addition, the force receiving member 30 has a front force receiving surface 30a and a rear force receiving surface 30b. The front force receiving surface 30a can receive a force from the front, and the rear force receiving surface 30b can receive a force from the rear. The front force receiving surface 30a and the rear force receiving surface 30b both extend beyond the pull handle 20 in the left-right direction of the puller 01. In this way, the front force receiving surface 30a and the rear force receiving surface 30b can receive forces respectively, so that the force receiving member 30 can receive stable forces in the front-rear direction, thereby preventing the puller 01 from moving relative to the zipper puller seat 02, and ensuring the stability of the puller 01.

[0037] To achieve the limiting effect on the puller 01, the zipper puller seat 02 can be provided with a first engagement groove 022a extending in the front-rear direction and a second engagement groove 022b extending in the left-right direction. In this way, when the puller 01 cooperates with the zipper puller seat 02, at least part of the pull handle 20 can be embedded in the first engagement groove 022a to be limited in the left-right direction by the left and right sidewalls of the first engagement groove 022a; and at least part of the force receiving member 30 can be embedded in the second engagement groove 022b to be limited in the front-rear direction by the front and rear sidewalls of the second engagement groove 022b in contact with the front force receiving surface 30a and the rear force receiving surface 30b of the force receiving member 30. In addition, the groove bottom of the first engagement groove 022a can support the pull handle 20, and the groove bottom of the second engagement groove 022b can also support the force receiving member 30.

[0038] Based on the above arrangement, the zipper puller seat 02 can stably contact the puller 01 from the front, rear, left and right directions, ensuring the stability of the connection between the two.

[0039] In the embodiment, when the puller 01 cooperates with the zipper puller seat 02, the force receiving member 30 can be located in the second engagement groove 022b. The sidewall surfaces of the second engagement groove 022b in the front-rear direction are respectively a first limiting surface and a second limiting surface. The first limiting surface can abut against the rear force receiving surface 30b, and the second limiting surface can abut against the front force receiving surface 30a, so as to ensure the stability of the force receiving member 30 in the front-rear direction.

[0040] In some embodiments, the zipper puller seat 02 can include a supporting portion 021 and an engagement portion 022 provided on the supporting portion 021. The supporting portion 021 is used to carry the puller body 10, and the engagement portion 022 is used to cooperate with the pull handle 20 and the force receiving member 30 respectively.

[0041] The rear end region of the supporting part 021 can be provided with a supporting surface 0211, which can be used to carry the puller 01; the engaging part 022 can be provided with a first engaging groove 022a and a second engaging groove 022b, and the supporting surface 0211, the first engaging groove 022a and the second engaging groove 022b are sequentially arranged from back to front, wherein the first engaging groove 022a extends along the front-rear direction of the zipper puller 02, the second engaging groove 022b extends along the left-right direction of the zipper puller 02, and the first engaging groove 022a and the second engaging groove 022b are in communication.

[0042] Based on the above arrangement, in the case that the puller 01 is pulled onto the zipper puller 02, the puller body 10 can be located on the supporting surface 0211 to limit the puller body 10 in the up-down direction by the supporting surface 0211, the pull handle 20 (such as the first handle section 21 of the pull handle 20) can be located in the first engaging groove 022a to limit the pull handle 20 by the groove walls on both sides of the first engaging groove 022a in the left-right direction, and the force receiving member 30 can be located in the second engaging groove 022b to limit the force receiving member 30 by the groove walls on both sides of the second engaging groove 022b in the front-rear direction. Based on this, the respective parts of the puller 01 can be limited by the respective parts of the zipper puller 02 to ensure that the puller 01 remains stationary in the up-down, front-rear and left-right directions, thereby improving the stability of the puller 01 on the zipper puller 02.

[0043] In the embodiment of the present application, the puller body 10 is used to cooperate with the chain teeth, so that the chain teeth can be combined or separated during the reciprocating movement of the puller body 10; the force receiving member 30 bears the force from the front and the force from the back through the front force receiving surface 30a and the rear force receiving surface 30b respectively, and the pull handle 20 is used to transmit the external force received by the force receiving member 30 to the puller body 10, so that the puller body 10 can move.

[0044] Based on the above structure, in the case that the puller 01 is used to cooperate with the zipper puller 02, the pull handle 20 and the force receiving member 30 can be used to cooperate with the zipper puller 02 respectively to ensure the reliability of the cooperation between the puller 01 and the zipper puller 02. Compared with the cooperation mode of the zipper head and the zipper slider in the related art, the cooperation and limitation between the puller 01 and the zipper puller 02 in the embodiment of the present application can prevent the puller 01 from rotating relative to the zipper puller 02 during the reciprocating movement, thereby improving the overall stability of the puller 01 and preventing the puller 01 from swinging and deviating.

[0045] When the two need to be separated, the puller 01 can be rotated relative to the zipper traction seat 02 by applying an upward force to the force receiving member 30, so that the force receiving member 30 and the pull handle 20 are respectively separated from the first engagement groove 022a and the second engagement groove 022b, and the separation of the puller 01 and the zipper traction seat 02 is realized.

[0046] Reference Figure 2 In some embodiments, the pull handle 20 can include a first handle segment 21 and a second handle segment 22 connected to each other. The puller connecting end 211 is one end of the first handle segment 21 away from the second handle segment 22, the force receiving connecting end 222 is one end of the second handle segment 22 away from the first handle segment 21, and the second handle segment 22 is arranged at an angle with the first handle segment 21 in a plane formed by the front-rear direction and the up-down direction.

[0047] Based on the above arrangement, by the angle between the second handle segment 22 and the first handle segment 21, the pull handle 20 in a bent shape can be formed, which can not only fix the puller connecting end 211 of the first handle segment 21 with the puller body 10, but also make the force receiving connecting end 222 extend out of the puller body 10 in a direction away from the upper side wall 11 along the front-rear direction and the up-down direction.

[0048] Optionally, the angle between the second handle segment 22 and the first handle segment 21 can range from 75° to 90°, for example, including 75°, 80°, 85°, 90°, etc., and of course, can also be other degrees, which are not limited here.

[0049] In some more specific embodiments, the first handle segment 21 can extend along the up-down direction and be arranged obliquely forward, in which case, even if the second handle segment 22 extends along the front-rear direction, the pull handle 20 can also extend forward and obliquely close to the puller body 10.

[0050] In some more specific embodiments, the second handle segment 22 can extend along the front-rear direction, and the force receiving connecting end 222 can gradually approach the upper side wall 11, in which case, even if the first handle segment 21 extends along the up-down direction, the pull handle 20 can also extend forward and obliquely close to the puller body 10.

[0051] In some more specific embodiments, the first handle segment 21 can extend along the up-down direction and be arranged obliquely forward, and the second handle segment 22 can extend along the front-rear direction and gradually approach the upper side wall 11.

[0052] Optionally, the first handle segment 21 can include a first side edge 213 and a second side edge 214. The first side edge 213 extends from the upper side wall 11 to the second handle segment 22 in the up-down direction, and the second side edge 214 is located behind the first side edge 213 and extends to the second handle segment 22 from the upper side wall in the forward-up direction. Based on this, the first handle segment 21 can be inclined to extend in the forward-up direction.

[0053] Based on the above various embodiments, the pull handle 20 and the force receiving member 30 can be effectively prevented from contacting the teeth to affect the normal movement of the puller 01, and after the puller 01 is installed in cooperation with the zipper traction seat 02, the cooperation stability of the puller 01 and the zipper traction seat 02 can be improved, so that the puller 01 is not easy to be separated from the zipper traction seat 02, and the rotation of the puller 01 relative to the zipper traction seat 02 is not hindered.

[0054] In some more specific embodiments, the pull handle 20 can be a fin-shaped plate member. In this case, the first handle segment 21 and the second handle segment 22 can both be strip-shaped plate members, and the thickness direction of the strip-shaped plate members is the left-right direction of the puller 01. Of course, the pull handle 20 can also be other shapes, as long as the force receiving connection end 222 of the pull handle 20 extends out of the puller body 10 in the forward-backward direction and the up-down direction away from the upper side wall 11, and the specific form is not limited.

[0055] Optionally, the connection between the first handle segment 21 and the second handle segment 22 can adopt a circular arc transition to alleviate the stress concentration problem at the connection. In addition, the edges of the first handle segment 21 and the second handle segment 22 can also be chamfered or rounded to make the edges of the pull handle 20 not sharp, so as to prevent the edges of the pull handle 20 from scratching the fingers of the person applying force.

[0056] Optionally, the first handle segment 21 can be provided with a through hole 212 that penetrates the first handle segment 21 in the left-right direction. It should be noted here that the through hole 212 can be a weight-reducing hole, which is beneficial to reduce the weight of the puller 01. In addition, by providing the through hole 212, the connection relationship between the puller 01 and the zipper traction seat 02 can be further increased. For example, the zipper traction seat 02 can be provided with a protruding buckle that can be connected with the through hole 212 to improve the stability of the connection between the puller 01 and the zipper traction seat 02.

[0057] To limit the pull handle 20, the engagement portion 022 can include a fork arm structure 0221 located near the supporting surface 0211 of the supporting portion 021, and the fork arm structure 0221 is provided with a first engagement groove 022a. Based on this, in the case where the puller 01 cooperates with the zipper traction seat 02, the first handle segment 21 can be embedded into the first engagement groove 022a to limit the first handle segment 21 by the left and right side walls of the first engagement groove 022a.

[0058] In addition, the joint portion 022 can further include a blocking structure 0223 located on the side of the fork arm structure 0221 away from the bearing surface 0211 and spaced apart from the fork arm structure 0221, and a base 0222 located between the blocking structure 0223 and the fork arm structure 0221. Based on this arrangement, a second joint groove 022b can be formed between the blocking structure 0223, the fork arm structure 0221, and the base 0222. When the puller 01 is fitted to the zipper traction seat 02, the force receiving member 30 of the puller 01 is inserted into the second joint groove 022b, and at the same time, the fork arm structure 0221 can limit the rear force receiving surface 30b of the force receiving member 30, and the blocking structure 0223 can limit the front force receiving surface 30a of the force receiving member 30, thereby limiting the force receiving member 30 in the front-rear direction to ensure the stability of the force receiving member 30 in the second joint groove 022b and prevent the force receiving member 30 from moving randomly in the front-rear direction.

[0059] Continuing to refer to Figure 2 In some embodiments, the force receiving member 30 can include a left force receiving portion 31 and a right force receiving portion 32. The left force receiving portion 31 extends leftward from the force receiving connecting end 222 and protrudes from the pull handle 20, and the right force receiving portion 32 extends rearward from the force receiving connecting end 222 and protrudes from the pull handle 20. The front force receiving surface 30a is the surface of the left force receiving portion 31 and the right force receiving portion 32 facing forward, and the rear force receiving surface 30b is the surface of the left force receiving portion 31 and the right force receiving portion 32 protruding from the pull handle 20 and facing rearward.

[0060] Based on this, the force receiving member 30 and the pull handle 20 can form a T-shaped structure, and accordingly, the first joint groove 022a and the second joint groove 022b can be arranged in a T shape. Therefore, when the puller 01 is fitted and installed with the zipper traction seat 02, the T-shaped structure can limit the puller 01 in both the left-right direction and the front-rear direction, thereby ensuring the stability of the puller 01.

[0061] In a normal use state, the cooperation limiting structure between the puller 01 and the zipper traction seat 02 can stably connect the puller 01 and the zipper traction seat 02 together. When it is necessary to separate the two, an upward force can be applied to the force receiving member 30 to enable the puller 01 to rotate relative to the zipper traction seat 02, thereby causing the force receiving member 30 and the pull handle 20 to respectively disengage from the second joint groove 022b and the first joint groove 022a, and achieving the separation of the puller 01 and the zipper traction seat 02.

[0062] To further avoid the force receiving part 30 of the puller 01 from being separated from the second engagement groove 022b by itself when encountering bumps and the like, the engagement portion 022 can further include a clamping protrusion 0224 movable in the front-rear direction, which is arranged on the blocking structure 0223 and at least part of which protrudes above the second limiting surface into the second engagement groove 022b.

[0063] Based on the above arrangement, in the initial state, at least part of the clamping protrusion 0224 protrudes into the second engagement groove 022b; during the embedding of the force receiving part 30 into the second engagement groove 022b, the clamping protrusion 0224 can be extruded to make at least part of the clamping protrusion 0224 retract outside the second engagement groove 022b, so that the force receiving part 30 can enter the second engagement groove 022b; after the force receiving part 30 completely enters the second engagement groove 022b, at least part of the clamping protrusion 0224 again protrudes into the second engagement groove 022b and abuts against the upper surface of the force receiving part 30, thereby limiting the force receiving part 30 in the up-down direction to prevent the force receiving part 30 from being separated from the second engagement groove 022b, and ensuring the stability of the cooperation between the puller 01 and the zipper puller 02.

[0064] To enable the clamping protrusion 0224 to retract outside the second engagement groove 022b without interfering with the embedding of the force receiving part 30 into the second engagement groove 022b, the blocking structure 0223 in the embodiment of the present application can be provided with a containing space extending forward from the second engagement groove 022b in the front-rear direction, which provides a retraction space for the clamping protrusion 0224 to prevent interference between the clamping protrusion 0224 and the blocking structure 0223.

[0065] To enable the clamping protrusion 0224 to automatically protrude into the second engagement groove 022b, the clamping protrusion 0224 can include an elastic cantilever, one end of which is connected to the blocking structure 0223, and the other end of which is provided with a convex block that can protrude above the second limiting surface into the second engagement groove 022b in the natural state of the elastic cantilever, and the convex block can be retracted into the containing space by elastic deformation of the elastic cantilever in the front-rear direction away from the second engagement groove 022b.

[0066] Based on the above arrangement, in the natural state of the elastic cantilever, the convex block can protrude into the second engagement groove 022b; when the convex block is extruded by the force receiving part 30, it can drive the elastic cantilever to elastically deform, causing the convex block to retract into the containing space outside the second engagement groove 022b, so that the force receiving part 30 can be embedded into the second engagement groove 022b; after the force receiving part 30 is completely embedded into the second engagement groove 022b, the extrusion on the convex block is removed, at which time the elastic cantilever can elastically return and drive the convex block to protrude into the second engagement groove 022b again, so as to limit the force receiving part 30 by the convex block.

[0067] Optionally, the blocking structure 0223 can be provided with a relief hole or a relief groove, and the accommodation space is formed through the relief hole or the relief groove. One end of the elastic cantilever is connected to the hole wall of the relief hole or the groove wall of the relief groove, and the convex block can be retracted into the relief hole or the relief groove under the extrusion of the force receiving part 30, so as to avoid interference with the blocking structure 0223.

[0068] In other embodiments, the clamping convexity 0224 can also be connected to the blocking structure 0223 in the front-rear direction to enable the clamping convexity 0224 to protrude into the second engagement groove 022b or retract out of the second engagement groove 022b. The clamping convexity 0224 can be connected to the blocking structure 0223 through an elastic member.

[0069] In some embodiments, the left force receiving part 31 and the right force receiving part 32 can each have a rectangular cross section in the plane formed by the front-rear direction and the up-down direction. On the one hand, this can increase the strength of the left force receiving part 31 and the right force receiving part 32, and on the other hand, it can also increase the contact area of the left force receiving part 31 and the right force receiving part 32 with the zipper puller seat 02, thereby improving the stability of the cooperation between the puller 01 and the zipper puller seat 02.

[0070] In other embodiments, the left force receiving part 31 and the right force receiving part 32 can each have a circular, elliptical, or other shape in the plane formed by the front-rear direction and the up-down direction, and the specific form is not limited.

[0071] Reference Figure 2 and Figure 3 In some embodiments, the puller body 10 can have a lower side wall 12 below the chain tooth channel M, which is spaced apart from the upper side wall 11. In addition, the lower side wall 12 and the upper side wall 11 can be connected by a connecting column 13, and the connecting column 13 is located at the front end of the upper side wall 11 and the lower side wall 12.

[0072] In addition, the puller body 10 can also include left and right blocking edges 14 and 15 that are spaced apart and opposite in the left-right direction. The left blocking edge 14 is connected to the left end of the lower side wall 12, and the right blocking edge 15 is connected to the right end of the lower side wall 12, and the left and right blocking edges 14 and 15 each have a certain spacing with the upper side wall 11. Alternatively, the left blocking edge 14 is connected to the left end of the upper side wall 11, and the right blocking edge 15 is connected to the right end of the upper side wall 11, and the left and right blocking edges 14 and 15 each have a certain spacing with the lower side wall 12. Based on this, the upper side wall 11, the lower side wall 12, the connecting column 13, the left blocking edge 14, and the right blocking edge 15 can collectively enclose the chain tooth channel M.

[0073] Optionally, the lower side wall 12 can be provided with a positioning block 40 protruding from the wall surface of the lower side wall 12 away from the tooth channel M. Correspondingly, the bearing surface 0211 can be provided with a positioning hole or a positioning groove 0212 for cooperation. The cooperation between the positioning block 40 and the positioning hole or the positioning groove 0212 can further improve the cooperation stability between the puller 01 and the zipper puller seat 02, and ensure the position accuracy of the puller 01. Exemplarily, the positioning block 40 can be a positioning rod, a positioning pin, a positioning protrusion or the like.

[0074] In some embodiments, in a plane formed by the front-rear direction and the left-right direction, the cross-sectional area of the first handle section 21 is greater than the cross-sectional area of the second handle section 22. Based on this arrangement, on the one hand, the connection area of the pull handle 20 and the puller body 10 can be increased to improve the reliability and firmness of the connection, and on the other hand, the strength of the first handle section 21 can be greater than that of the second handle section 22, thereby improving the load bearing capacity of the first handle section 21. It should be noted here that during the process of pulling the puller 01, installing the puller 01 to the zipper puller seat 02 or disassembling the puller 01 from the zipper puller seat 02, the first handle section 21 is the main component to bear the load, and increasing the strength of the first handle section 21 can prevent the first handle section 21 from deforming or breaking when bearing the load.

[0075] In some embodiments, in the front-rear direction, the size of the first handle section 21 at the position connected to the upper side wall 11 can be greater than half of the entire wall surface size of the upper side wall 11. Based on this, the area of the connection region of the first handle section 21 and the upper side wall 11 can be increased, thereby improving the connection reliability and making the connection more stable, and further improving the load bearing capacity of the puller 01. Exemplarily, in the front-rear direction, the size of the first handle section 21 at the position connected to the upper side wall 11 can be 2 / 3, 3 / 4 or the like of the entire wall surface size of the upper side wall 11. Of course, it can also be other proportions, which are not limited here.

[0076] In some embodiments, the puller body 10, the pull handle 20 and the force receiving member 30 can be an integral structure. This kind of structure can improve the strength of the puller 01 as a whole, and can shorten the production cycle of the puller 01 and improve the production efficiency.

[0077] In other embodiments, the pull handle 20 and the puller body 10 can be fixedly connected, such as welding, bonding, riveting, clamping, screwing and the like; the force receiving member 30 and the pull handle 20 can be fixedly connected, such as welding, bonding, riveting, clamping, screwing and the like.

[0078] The embodiments of the present application are described above with reference to the accompanying drawings, but the present application is not limited to the specific embodiments described above, and the specific embodiments described above are merely illustrative, but not restrictive, and a person of ordinary skill in the art can make many forms under the inspiration of the present application without departing from the purpose of the present application and the scope protected by the claims.
