Description

Technical Field

[0001] This application belongs to the technical field of zippers, specifically relating to a zipper pull and a zipper tip. Background Technology

[0002] The zipper head includes a zipper head body, a pull tab, a pull cord, and other structures. The pull tab is installed to the zipper head body, and the pull cord is installed to the pull tab, so that the user can move the zipper head along the chain teeth by holding and pulling the pull cord to achieve the engagement or disengagement of the chain teeth.

[0003] Some zipper pulls in related technologies involve wrapping the pull cord around the pull tab and connecting it to the pull tab by tying a knot. However, this method is prone to the knot loosening, causing the pull cord to easily detach from the pull tab. Furthermore, the knotted part of the pull cord is relatively large and protrudes from the pull tab, affecting the appearance of the zipper pull. Utility Model Content

[0004] The purpose of this application is to provide a pull tab that can solve problems such as pull cords easily falling off and poor appearance.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows: This application provides a pull tab assembly including: a pull tab body; The rear end area of ​​the pull tab body is provided with a first mounting hole for connecting with the pull body; The front end area of ​​the pull tab body is provided with a second mounting hole for the pull rope to pass through, and the second mounting hole penetrates the pull tab body along the thickness direction of the pull tab body; The pull tab body is also provided with a locking hole for passing a pull rope through. The locking hole extends from the hole wall of the second mounting hole to the front end face of the pull tab body and passes through the front end face.

[0006] This application embodiment also provides a zipper head, including: a zipper body and the above-mentioned zipper tab; The pull tab is connected to the pull body through the first mounting hole.

[0007] In this embodiment, the pull cord can be connected to the pull body through the first mounting hole, so that the pull body can slide on a pair of chain teeth by applying force to the pull tab, allowing the pair of chain teeth to engage or disengage. The pull cord can also pass through the second mounting hole, and pass through the locking hole from the hole wall of the second mounting hole, and also pass through the front end face of the pull tab body, allowing the pull cord to pass through the locking hole. Based on this, the pull cord can be knotted at the second mounting hole, and the knot of the pull cord is located in the second mounting hole, thereby effectively reducing the protrusion height of the knotted pull cord, improving the appearance performance, improving the user experience, and, since part of the knotted pull cord is located in the locking hole, the locking hole can play a certain restrictive role for the pull cord, making it less likely for the pull cord to loosen and detach from the pull tab, thereby ensuring the firmness of the installation between the pull cord and the pull tab.

[0010] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0011] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0012] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0013] refer to Figures 1 to 5This application discloses a pull tab 10 for connecting to the pull body of a pull head, so that the pull body can be moved by applying force to the pull tab 10. Optionally, the pull tab 10 and the pull body can be movably connected to allow the pull tab 10 to change its orientation relative to the pull body, thereby realizing bidirectional movement of the pull head. The disclosed pull tab 10 includes a pull tab body 10a.

[0014] To connect the pull tab 10 to the pull body, a first mounting hole 11 can be provided in the rear end region of the pull tab body 10a. The first mounting hole 11 is used to connect with the pull body, so that by applying force to the pull tab 10, the pull body can be driven to slide on a pair of chain teeth, allowing the pair of chain teeth to engage or disengage. Optionally, a hook structure can be provided on the pull body. The hook structure can hook onto the first mounting hole 11 to connect the pull tab 10 to the pull body; and the hook structure can also move in the first mounting hole 11 to achieve relative movement between the pull tab 10 and the pull body, thereby changing the orientation of the pull tab 10.

[0015] To mount the pull cord 20 onto the pull tab 10, a second mounting hole 12 may be provided at the front end region of the pull tab body 10a. The second mounting hole 12 is used for the pull cord 20 to pass through, and the second mounting hole 12 extends through the pull tab body 10a along its thickness direction. Based on this, the end of the pull cord 20 can pass through the second mounting hole 12, so that the pull cord 20 can be knotted at the second mounting hole 12.

[0016] It should be noted that the area of ​​the pull tab body 10a used to connect with the pull body is the rear end area, and the area used to connect with the pull rope 20 is the front end area.

[0017] In addition, the pull rope 20 may include a first rope segment 21a and a second rope segment 21b, the first rope segment 21a and the second rope segment 21b are arranged side by side and their ends are connected so that the pull rope 20 can be connected to the pull piece 10 by knotting.

[0018] Furthermore, the pull tab body 10a may also be provided with a locking hole 13 for the pull cord 20 to pass through. The locking hole 13 extends from the wall of the second mounting hole 12 toward the front end face 10a1 of the pull tab body 10a and passes through the front end face 10a1. Based on this, the knotted pull cord 20 can pass through the locking hole 13, so that part of the pull cord 20 is located in the locking hole 13 and does not protrude out of the surface of the pull tab body 10a. This can help reduce the space occupied by the pull cord 20 and improve the appearance of the connection between the pull tab 10 and the pull head. In addition, the locking hole 13 can also play a certain role in restricting the pull cord 20, so as to alleviate the problem that the knot of the pull cord 20 is loose and the pull cord 20 is easy to detach from the pull tab 10, thus ensuring the firmness of the installation between the pull cord 20 and the pull tab 10.

[0019] like Figure 2As shown, in some embodiments, the locking hole 13 can extend in a straight line, that is, the locking hole 13 extends in a straight line from the hole wall of the second mounting hole 12 to the front end face 10a1 of the pull tab body 10a, so as to improve the convenience of the pull rope 20 passing through the locking hole 13.

[0020] Optionally, the locking hole 13 can extend along the front-back direction of the pull tab body 10a, so that the pull cord 20 passing through the locking hole 13 can extend in the front-back direction. Alternatively, the locking hole 13 can extend at an acute angle to the front-back direction of the pull tab body 10a, so that the pull cord 20 passing through the locking hole 13 can extend in an inclined direction deviating from the front-back direction. It should be noted that the extension direction of the locking hole 13 can be set according to actual needs, and its specific form is not limited.

[0021] In some embodiments, the locking hole 13 can be a smooth hole, which allows the pull rope 20 to pass through smoothly and effectively avoids the pull rope 20 from being scratched by sharp parts of the locking hole 13, thus helping to extend the service life of the pull rope 20.

[0022] refer to Figure 5 In some embodiments, the left end face 10a2 of the pull tab body 10a may be provided with a slot 14 for engaging the pull cord 20, i.e., a left-side slot that extends through the pull tab body 10a along its thickness direction. Based on this, when the pull cord 20 is sleeved on the outside of the pull tab body 10a, the first segment 21a of the pull cord 20 can be engaged in the left-side slot, preventing the first segment 21a from protruding beyond the left end face 10a2 of the pull tab body 10a. This prevents the first segment 21a from moving freely at the left end face 10a2 of the pull tab body 10a, ensuring its stability and further alleviating the problem of the pull cord 20 becoming loose. Furthermore, it improves the appearance of the engagement point between the first segment 21a and the pull tab body 10a.

[0023] Similarly, the right end face 10a3 of the pull tab body 10a can be provided with a slot 14 for engaging the pull cord 20, i.e., a right-side slot that extends through the pull tab body 10a along its thickness direction. Based on this, when the pull cord 20 is sleeved on the outside of the pull tab body 10a, the second cord segment 21b of the pull cord 20 can be engaged in the right-side slot, preventing the second cord segment 21b from protruding beyond the right end face 10a3 of the pull tab body 10a. This prevents the second cord segment 21b from moving freely at the right end face 10a3 of the pull tab body 10a, ensuring its stability and further alleviating the problem of the pull cord 20 becoming loose. Furthermore, it improves the appearance of the engagement point between the second cord segment 21b and the pull tab body 10a.

[0024] Furthermore, the groove 14 on the left end face 10a2 is inclined to the left rear of the pull tab body 10a. When the pull rope 20 is connected to the pull tab 10, the groove 14 on the left end face 10a2 can be aligned with the extension direction of the first rope segment 21a, and the front side wall of the groove 14 can generate a supporting force on the first rope segment 21a towards the right rear. Thus, when the pull rope 20 is pulled, the first rope segment 21a can have a component force in the direction of the center line, thereby reducing the risk of the first rope segment 21a disengaging from the groove 14 on the left end face 10a2 and improving the connection stability between the first rope segment 21a and the pull tab body 10a.

[0025] Furthermore, the groove 14 located on the right end face 10a3 is inclined towards the right rear of the pull tab body 10a. When the pull rope 20 is connected to the pull tab 10, the groove 14 on the right end face 10a3 can be aligned with the extension direction of the second rope segment 21b, and the front side wall of the groove 14 can generate a supporting force on the second rope segment 21b towards the left rear. Thus, when the pull rope 20 is pulled, the second rope segment 21b can have a component force towards the center line, thereby reducing the risk of the second rope segment 21b disengaging from the groove 14 on the left end face 10a2 and improving the connection stability between the second rope segment 21b and the pull tab body 10a.

[0026] Optionally, in the left-right direction of the pull tab body 10a, the slot 14 of the left end face 10a2 is located to the left of the second mounting hole 12, and the slot 14 of the right end face 10a3 is located to the right of the second mounting hole 12.

[0027] After the pull cord 20 is knotted, the end of the pull cord 20 passes through the second mounting hole 12 from one side of the pull tab body 10a in the thickness direction; the first cord segment 21a passes through the slot 14 of the left end face 10a2 and extends to the other side of the pull tab body 10a in the thickness direction, and the first cord segment 21a continues to extend forward and toward the center line of the pull tab body 10a so that the first cord segment 21a passes through the slot 13; similarly, the second cord segment 21b passes through the slot 14 of the right end face 10a3 and extends to the other side of the pull tab body 10a in the thickness direction, and the second cord segment 21b continues to extend forward and toward the center line of the pull tab body 10a so that the second cord segment 21b passes through the slot 13. Based on this, when the pull rope 20 is pulled, the first rope segment 21a and the second rope segment 21b can respectively have a tendency to move towards the center line of the pull plate body 10a. At the same time, the grooves 14 provided on the left end face 10a2 and the right end face 10a3 respectively provide support for the first rope segment 21a and the second rope segment 21b towards the center line, thereby effectively alleviating the problem of the pull rope 20 loosening and ensuring the reliability and firmness of the connection between the pull rope 20 and the pull plate 10.

[0028] refer to Figure 1 and Figure 2 In some embodiments, along the front-rear direction of the pull tab body 10a, the slot 14 can be located between the first mounting hole 11 and the second mounting hole 12. In this way, the first rope segment 21a and the second rope segment 21b of the pull rope 20 can be respectively limited between the first mounting hole 11 and the second mounting hole 12, thereby allowing the slot 14 to avoid the first mounting hole 11 and the second mounting hole 12. This prevents the distance between the slot 14 and the first mounting hole 11 or the second mounting hole 12 from being too small, which would reduce the strength of the pull tab body 10a and help extend the service life of the pull tab body 10a.

[0029] refer to Figure 2 and Figure 4 In some embodiments, a groove 15 may be provided on one side surface of the pull tab body 10a along the thickness direction. The groove 15 extends from the slots 14 on the left and right sides towards the second mounting hole 12 and to the hole wall of the second mounting hole 12 in the area away from the slot 13. Based on this, the groove 15 can limit the pull cord 20, thereby alleviating the problem of the knot easily loosening due to the pull cord 20 moving freely in the left and right direction. In addition, the groove 15 can also accommodate the pull cord 20, thereby reducing the thickness of the pull cord 20 protruding from the surface of the pull tab body 10a, thus reducing the volume of the entire pull head assembly and improving the user experience.

[0030] refer to Figure 1 and Figure 3 In some embodiments, the thickness of the pull tab body 10a in the left and right sides of the second mounting hole 12 gradually increases from the middle of the second mounting hole 12 to the front end face 10a1. This can improve the strength of the area and enable the area to withstand greater tensile force.

[0031] It should be noted that the card hole 13 is located between the front side wall of the second mounting hole 12 and the front end face 10a1 of the pull tab body 10a. This will reduce the strength of the area. By gradually increasing the thickness of this area, its strength can be improved so that it will not break when subjected to large tensile forces.

[0032] In some embodiments, the pull tab body 10a can be an integral structure, which can improve its own strength and shorten the manufacturing cycle and improve manufacturing efficiency.

[0033] Optionally, the pull sheet body 10a can be an injection-molded integral part or a machined integral part, etc.

[0034] Based on the aforementioned pull tab 10, this application embodiment also discloses a pull head, which includes a pull body and the aforementioned pull tab 10, wherein the pull tab 10 is connected to the pull body through a first mounting hole 11.

[0035] Optionally, refer to Figure 4 and Figure 5 The pull cord 20 may include a cord body 21 and a handle 22. The cord body 21 may be connected to the pull tab 10 by knotting; wherein, the cord body 21 may include a first cord segment 21a and a second cord segment 21b; the handle 22 may be fixed to the ends of the first cord segment 21a and the second cord segment 21b respectively, so that the user can hold it and pull the pull head 10 by pulling the cord 20.

[0036] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
