[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A handle, comprising:

[0008] The handle body is a strip structure with flexible deformation function;

[0009] The kit is a tubular structure through which the handle body passes;

[0010] One end of the handle body is provided with a first locking block, and the end of the handle body away from the first locking block is provided with a first locking groove. By bending the handle body, the first locking block is at least partially inserted into the first locking groove.

[0011] The kit is fitted onto the bent handle body. When the handle body is bent and the first locking block is at least partially inserted into the first slot, the kit moves to at least partially overlap with the first locking block, so as to place the kit in a limiting position that restricts the first locking block within the first slot.

[0012] A blocking part is provided at the tail of the handle body and is used to prevent the kit from disengaging from the restricted position.

[0013] Furthermore, in this invention, the maximum inner diameter of the inner hole of the kit is less than the maximum width of the blocking portion, in order to prevent the kit from detaching from the handle body from the direction of the blocking portion.

[0014] Furthermore, in this invention, the blocking part is located at one end of the handle body near the first slot, and the first slot is formed by a portion of the blocking part being sunk down, so that the first card block can be completely inserted into the first slot.

[0015] Furthermore, in this utility model, the first card block has a T-shaped structure, the first card slot has a shape that matches the first card block, and the first card block and the first card slot are interference fit.

[0016] Furthermore, in this invention, the cross-section of the handle body is semi-circular, which is used to make the cross-section formed after the handle body is bent into a circle, and the cross-section of the blocking part is a circle with a diameter larger than that of the handle body.

[0017] Furthermore, in this invention, the inner hole of the kit is a conical surface with its tip facing away from the first card block, and the minimum diameter of the conical surface is smaller than the diameter of the blocking part.

[0018] Furthermore, the present invention provides a frustum at one end of the kit away from the blocking part, the inner diameter of the frustum being smaller than the diameter of the blocking part, so that when the kit is in the restricted position, the blocking part is completely located within the kit.

[0019] Furthermore, the present invention provides a second locking block at one end of the handle body near the first locking slot, and a second locking slot that cooperates with the second locking block at one end of the handle body away from the second locking block. When the handle body is bent and the first locking block is at least partially inserted into the first locking slot, the second locking block is at least partially inserted into the second locking slot.

[0020] Furthermore, in this invention, the second locking block is a right-angled trapezoidal structure, and the side of the second locking block near the first locking block forms a limiting area with the blocking part to prevent the kit from disengaging from the limiting position.

[0021] A zipper assembly includes a zipper head and a pull tab, the pull tab having a through hole, and also includes a handle as described in any of the above claims. When the handle body passes through the through hole and is bent to allow the first locking block to enter the first locking slot, a fixed connection between the handle and the zipper head is achieved.

[0022] The handle provided by this utility model uses a strip structure with flexible deformation function as the handle body, which enables it to bend easily, facilitating its connection with the pull tab of the handle head. This reduces the overall number of handle parts. The kit is a tubular structure through which the handle body passes. One end of the handle body has a first locking block, and the end of the handle body away from the first locking block has a first locking groove. By bending the handle body, the first locking block is at least partially inserted into the first locking groove. The kit is fitted onto the bent handle body. When the handle body is bent and the first locking block is at least partially inserted into the first locking groove, that is, by engaging the first locking block into the first... Within a slot, the bent handle body remains bent. The kit at least partially overlaps with the first locking block, positioning the kit in a restraining position that confines the first locking block within the first slot. This prevents the first locking block from detaching from the first slot, ensuring a secure connection between the handle body and the pull head. A blocking part is located on the handle body to prevent the kit from detaching from the restraining position. The kit offers superior ease of assembly. The synergistic action of the snap-fit ​​structure not only makes it easy to join the handle ends but also significantly improves the stability of the joined parts, effectively preventing loosening and providing a better user experience.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] The core of this utility model is to provide a handle that simplifies the production process, reduces manufacturing difficulty, and helps improve production efficiency.

[0036] Another core aspect of this invention is providing a pull head assembly that includes the aforementioned handle.

[0037] Please refer to Figure 4 A handle includes a handle body 1, a kit 2, and a blocking part 5. The handle body 1 is a strip structure with flexible deformation function. The kit 2 is a tubular structure through which the handle body 1 passes. One end of the handle body 1 is provided with a first locking block 3, and the end of the handle body 1 away from the first locking block 3 is provided with a first locking groove 4. By bending the handle body 1, the first locking block 3 is at least partially inserted into the first locking groove 4. The kit 2 is fitted onto the bent handle body 1. When the handle body 1 is bent and the first locking block 3 is at least partially inserted into the first locking groove 4, the kit 2 moves to at least partially overlap with the first locking block 3, so that the kit 2 is in a restricted position that restricts the first locking block 3 within the first locking groove 4. The blocking part 5 is provided at the tail of the handle body 1 and is used to prevent the kit 2 from falling out of the restricted position.

[0038] It should be noted that in this embodiment of the present invention, the first locking block 3 and the first locking groove 4 are respectively placed at both ends of the handle body 1, and the first locking block 3 is inserted into the first locking groove 4 by bending the handle body 1 and connecting the ends.

[0039] Optionally, in some embodiments, the handle body 1, the first locking block 3, and the first locking groove 4 are manufactured by injection molding in an integral manner, which is beneficial to improving the production efficiency of the handle body 1.

[0040] Optionally, in some embodiments, the handle body 1 is made of plastic and is produced by injection molding. Handles made in this way and using this material are stronger, easier to produce, and more flexible.

[0041] Optionally, in some embodiments, the kit 2 may adopt a tubular structure of any shape, such as a circular or polygonal cross-section, which can be selected according to the clothing design.

[0042] In the above embodiment, during implementation, the handle and the pull tab of the handle head cooperate with the through hole. Specifically, firstly, the kit 2 is passed through one end of the handle body 1, then one end of the handle body 1 is passed through the through hole of the pull tab, and after the end of the handle body 1 passing through the through hole of the pull tab is passed through the kit 2, the first locking block 3 is at least partially inserted into the first locking groove 4, and then the kit 2 is slid so that the kit 2 and the first locking block 3 at least partially overlap, so that the kit 2 is in a limiting position that restricts the first locking block 3 in the first locking groove 4, thereby completing the assembly and use of the handle as a whole.

[0043] In a specific implementation of this utility model, a strip structure with flexible deformation function is used as the handle body 1, which enables it to bend easily, facilitating its connection with the pull tab of the pull head. This reduces the overall number of handle components. The kit 2 is a tubular structure through which the handle body 1 passes. One end of the handle body 1 is provided with a first locking block 3, and the end of the handle body 1 away from the first locking block 3 is provided with a first locking groove 4. By bending the handle body 1, the first locking block 3 is at least partially inserted into the first locking groove 4. The kit 2 is fitted onto the bent handle body 1. When the handle body 1 is bent and the first locking block 3 is at least partially inserted into the first locking groove 4, that is, by engaging the first locking block 3 into the first locking groove 4... Within the slot 4, the bent handle body 1 remains bent. The kit 2 and the first locking block 3 at least partially overlap, positioning the kit 2 in a restrictive position that confines the first locking block 3 within the slot 4. The kit 2 prevents the first locking block 3 from disengaging from the slot 4, thus ensuring a secure connection between the handle body 1 and the pull head. The blocking part 5 is located on the handle body 1 and prevents the kit 2 from disengaging from the restrictive position. The assembly is remarkably convenient, and the synergistic action of the buckle structure not only makes it easy to splice the handle end to end but also significantly improves the stability after splicing, effectively preventing loosening and providing a better user experience. At the same time, it simplifies the production process, reduces manufacturing difficulty, and helps improve production efficiency.

[0044] Please refer to Figure 7In some embodiments, the maximum inner diameter of the inner hole of the kit 2 is less than the maximum width of the blocking part 5, in order to prevent the kit 2 from detaching from the handle body 1 in the direction of the blocking part 5. That is, by making the size of the blocking part 5 larger than the inner hole size through which the kit 2 can pass, the blocking part 5 can block the kit 2.

[0045] Optionally, in some embodiments, the blocking part 5 can take any shape, such as a strip structure or a circular structure, as long as its maximum size is greater than the inner hole size through which the kit 2 can pass. The shape of the blocking part 5 can be selected according to the clothing design.

[0046] Please refer to Figure 5 In some embodiments, the blocking part 5 is provided at one end of the handle body 1 near the first slot 4. The first slot 4 is formed by sinking part of the structure of the blocking part 5 so that the first block 3 can be completely inserted into the first slot 4. That is, by forming the first slot 4 by sinking the blocking part 5, the first block 3 can be completely inserted into the first slot 4. The kit 2 is used to partially overlap with the first block 3 and the first slot 4, thereby achieving the function of shielding the connection position, playing a role in concealing marks, and improving the aesthetics of the handle during installation and use.

[0047] Optionally, in some embodiments, the size of the kit 2 can be increased so that the kit 2 completely covers the shielding part, thereby completely shielding the connection position of the first card block 3 and the first card slot 4, further improving the aesthetics of the handle during installation and use.

[0048] Optionally, in some embodiments, the kit 2 and the blocking part 5 are connected by an interference fit. Specifically, the interference fit between the kit 2 and the blocking part 5 can increase the friction between the kit 2 and the blocking part 5, thereby improving the firmness of the handle assembly and use, and further preventing accidental opening.

[0049] Optionally, in some embodiments, the inner hole of the kit 2 is provided with anti-slip texture. Specifically, the anti-slip texture can further increase the friction between the kit 2 and the blocking part 5, thereby improving the firmness of the handle during assembly and use.

[0050] Please refer to Figure 3 In some embodiments, the first locking block 3 is a T-shaped structure, and the first locking groove 4 is a shape that cooperates with the first locking block 3. That is to say, by setting the first locking block 3 as a T-shaped structure and cooperating the first locking groove 4 with the first locking block 3, the offset of the first and last ends of the injection molded part after locking can be effectively limited. In particular, the T-shape can also limit the forward and backward movement, further improving the firmness of the handle assembly and use.

[0051] Optionally, in some embodiments, the first locking block 3 and the first locking groove 4 are interference-fitted, thereby increasing the friction between the first locking block 3 and the first locking groove 4 to improve the sturdiness of the assembled handle.

[0052] In other embodiments, the first card block 3 may also adopt other structures, such as circular, spherical, L-shaped or polygonal structures.

[0053] Please refer to Figure 2 In some embodiments, the handle body 1 has a semi-circular cross-section, which is used to make the cross-section formed after the handle body 1 is bent into a circle. The cross-section of the blocking part 5 is a circle with a diameter larger than that of the handle body 1. In other words, the handle body 1 with a semi-circular cross-section can make the handle body 1 round when assembled and used. The outer side of the round injection molded part is an arc surface, which makes the outer surface of the handle feel better and avoids cutting hands.

[0054] In other embodiments, the handle body 1 may also have a cross-sectional shape of other shapes, which can be selected according to the characteristics of clothing design. For example, the handle body 1 may be assembled into a polygonal structure.

[0055] Optionally, in some embodiments, in order to further improve the aesthetics of the handle body 1 during use, several protrusions can be evenly distributed along the length of the handle body 1, and grooves can be set at corresponding positions. When the handle body 1 is bent and folded, the protrusions are inserted into the grooves to prevent the handle body 1 from tilting up near the handle head.

[0056] Please refer to Figure 4 In some embodiments, the inner hole of the kit 2 is a conical surface with the tip facing away from the first latch block 3, and the minimum diameter of the conical surface is smaller than the diameter of the blocking part 5. The kit 2 with a conical structure can further improve the aesthetics of the handle assembly and use, and match the cylindrical pull head assembly.

[0057] Optionally, in some embodiments, the inner hole of the kit 2 is provided with a frustum 201, the diameter of which is smaller than the diameter of the blocking part 5. When the kit 2 is in the restricted position, the blocking part 5 is completely located inside the kit 2. In this position, the frustum 201 and the blocking part 5 are connected near the side of the pull head, thereby ensuring the blocking effect of the blocking part 5 on the kit 2.

[0058] Please refer to Figure 4. In some embodiments, a second locking block 7 is provided at the end of the handle body 1 near the first locking slot 4, and a second locking slot 6 that cooperates with the second locking block 7 is provided at the end of the handle body 1 away from the second locking block 7. When the handle body 1 is bent and the first locking block 3 is at least partially inserted into the first locking slot 4, the second locking block 7 is at least partially inserted into the second locking slot 6. That is to say, by adding the second locking block 7 and the second locking slot 6, the firmness of the handle body 1 after bending and folding is improved, and the loosening problem is effectively avoided.

[0059] Optionally, in some embodiments, the second card block 7 and the second card slot 6 are subjected to an interference fit to ensure the firmness of the connection between the second card block 7 and the second card slot 6.

[0060] Please refer to Figure 6 In some embodiments, the second locking block 7 is a right-angled trapezoidal structure. The side of the second locking block 7 closest to the first locking block 3 forms a restriction area 101 with the blocking part 5 to prevent the kit 2 from leaving the restriction position. That is, the maximum height of the second locking block 7 is higher than the minimum passing diameter of the kit 2, so that when the kit 2 enters the restriction area 101, it is restricted by the first locking block 3 and the blocking part 5 to prevent the kit 2 from leaving the handle body 1.

[0061] Alternatively, in some embodiments, the second block 7 may also take other shapes, as long as its maximum height is greater than the minimum passing diameter of the kit 2 to ensure the restraining effect on the kit 2.

[0062] Please refer to Figure 1 A zipper assembly includes a zipper head and a zipper tab. The zipper tab has a through hole and also includes the aforementioned handle. When the handle body 1 passes through the through hole and is bent so that the first locking block 3 enters the first locking slot 4, a fixed connection between the handle and the zipper head is achieved.

[0063] In other words, the key point of this utility model is that by inserting the first locking block 3 into the first locking groove 4, the bent handle body 1 is kept in a bent state. The kit 2 and the first locking block 3 overlap at least partially, so that the kit 2 is in a restrictive position that restricts the first locking block 3 within the first locking groove 4. Under the action of the kit 2, the first locking block 3 is prevented from separating from the first locking groove 4, thereby ensuring a firm connection between the handle body 1 and the pull head. The blocking part 5 is provided on the handle body 1 and is used to prevent the kit 2 from leaving the restrictive position. The assembly is convenient and the buckle structure works together to not only make it easy to complete the splicing of the handle head and tail, but also greatly improve the stability after splicing, effectively avoid the problem of loosening, and provide a better user experience. At the same time, it simplifies the production process, reduces manufacturing difficulty, and helps to improve production efficiency.

[0064] In addition to the handles disclosed in the above embodiments, this utility model also provides a zipper head assembly including the above-mentioned handles. For the structure of other parts of the zipper head assembly, please refer to the prior art, which will not be described in detail here.

[0065] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0066] The above provides a detailed description of a handle and pull head assembly provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model.
