Description

Technical Field

[0001] This utility model relates to the field of zipper technology, and more specifically, to a zipper pull structure and a zipper. Background Technology

[0002] Zippers, as a common connector, are widely used in clothing, bags, tents, and many other fields. With the development of the times and the continuous improvement of people's living standards, the requirements for product quality are also increasing.

[0003] In existing zipper pull technology, various techniques are employed to achieve the opening, closing, and locking functions of the zipper. Among these, the spring-loaded zipper pull is a common structure, primarily composed of a base, a spring clip, and a pull tab. The tail of the spring clip extends into the inner cavity of the spring head. When the spring-loaded zipper pull is assembled onto the zipper, the tip of the spring clip can lock or unlock the zipper teeth. The linkage between the pull tab and the spring clip raises and lowers the tip of the spring clip; that is, when the pull tab is raised to a certain angle, the tail of the spring clip rises, unlocking the zipper pull from the zipper teeth.

[0004] However, existing spring-loaded zipper pulls have obvious defects. When the pull tab is raised to a certain angle, the zipper pull cannot automatically reset, and the zipper pull and chain teeth are in an unlocked state. This can easily cause the zipper to open accidentally, causing inconvenience to users.

[0005] In summary, how to enable the zipper pull to automatically reset and lock with the zipper teeth after the zipper tab is lifted, thus preventing the zipper from opening accidentally, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a zipper pull structure and zipper that can effectively enable the zipper pull to automatically reset and lock with the zipper teeth after the zipper pull is lifted, thereby preventing the zipper from opening accidentally.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A zipper pull structure and zipper include a zipper pull base and a pull tab. The zipper pull base is provided with a clamping part. One end of the pull tab is rotatably disposed in the clamping part. The zipper pull also includes a spring. The first end of the spring is fixedly connected to the zipper pull base, and the second end of the spring engages with a zipper tooth.

[0009] The pull tab has a driving part, the spring has a driven part that cooperates with the driving part, and the spring has a deformable part, so that the pull tab rotates to drive the second end of the spring to disengage from the chain tooth and squeeze the deformable part to generate an elastic restoring force.

[0010] Preferably, the deformed portion is a concave trough formed in the middle section of the spring piece;

[0011] A first arch is formed between the deformable portion and the first end, and a second arch is formed between the deformable portion and the second end.

[0012] Preferably, the included angle formed by the deformed part is in the range of 45°-70°.

[0013] Preferably, the height-to-span ratio of the first arch and the second arch is 0.30-0.50.

[0014] Preferably, the pull head base is provided with a receiving cavity for accommodating the deformed part, and there is a gap between the bottom of the receiving cavity and the core plate of the pull head base.

[0015] Preferably, the driving part includes a pull tab crossbar disposed on the pull tab and cooperating with the clamp, and a pull tab protrusion disposed on the pull tab crossbar;

[0016] The driven part includes a spring hole formed in the spring piece, and the pull tab protrusion is inserted into the spring hole so that when the pull tab is pulled, one side of the pull tab protrusion abuts against the edge of the spring hole.

[0017] Preferably, the pull tab protrusion is provided with a protrusion structure to prevent the pull tab protrusion from detaching from the spring sheet hole.

[0018] Preferably, both sides of the clamp are provided with stops, which are used to limit the rotation angle of the pull tab.

[0019] Preferably, the driving part includes a pull tab crossbar disposed on the pull tab and cooperating with the clamp, and a pull tab hole formed in the pull tab crossbar;

[0020] The driven part includes a bend in the spring piece, the second end of the spring piece is inserted into the hole in the pull piece, and the bend abuts against the pull piece crossbar.

[0021] A zipper includes a zipper pull structure and two sets of zipper strips corresponding thereto, wherein the zipper pull structure is any of the zipper pull structures described above.

[0022] The zipper pull structure provided by this utility model, due to the setting of the deformation part, allows the deformation part to be squeezed simultaneously when the pull tab drives the second end of the spring to disengage from the zipper teeth. This causes the deformation part to generate an elastic restoring force. When the pull tab is no longer subjected to external force, the elastic potential energy of the deformation part is released, and the generated elastic restoring force can make the pull tab automatically reset, allowing the zipper pull locking pin to automatically lock with the zipper teeth, preventing the zipper pull from being accidentally unlocked, and solving the problem of the zipper pull not being able to automatically reset and the zipper pull and zipper teeth being in an unlocked state.

[0035] 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.

This application discloses a zipper pull structure and a zipper.

[0037] The core of this utility model is to provide a zipper pull structure.

[0038] Another core aspect of this invention is to provide a zipper that includes the aforementioned zipper pull structure.

[0039] Please refer to Figure 1 .

[0040] The zipper pull structure provided by this utility model includes a zipper pull base 1 and a pull tab 2. The zipper pull base 1 is provided with a clamping part 11. One end of the pull tab 2 is rotatably disposed in the clamping part 11. The zipper pull structure also includes a spring tab 3. The first end of the spring tab 3 is fixedly connected to the zipper pull base 1, and the second end of the spring tab 3 engages with the chain teeth. The pull tab 2 has a driving part 4, and the spring tab 3 has a driven part 5 that engages with the driving part 4. The spring tab 3 has a deformation part 31, so that the rotation of the pull tab 2 drives the second end of the spring tab 3 to disengage from the chain teeth and compresses the deformation part 31 to generate an elastic restoring force.

[0041] Specifically, the spring 3 has a first end and a second end. The pull head base 1 is provided with a mounting groove at the first end of the spring 3, and the first end of the spring 3 is fixed in the mounting groove. The pull head base 1 is provided with a locking hole at the second end of the spring 3. The second end of the spring 3 extends into the locking hole and cooperates with the chain teeth to achieve locking. A deformation part 31 is formed in the middle of the spring 3. The deformation part 31 can generate elastic restoring force through deformation. When there is no external force acting on the pull piece 2, it pushes the pull piece 2 back to reset, realizing automatic rebound.

[0042] The zipper base 1 is provided with a clamp 11, which makes it easy for the zipper 2 to rotate on the zipper base 1 without detaching from the zipper base 1. In cooperation with this, the zipper 2 has a driving part 4 and the spring 3 has a driven part 5. The driving part 4 and the driven part 5 cooperate to drive the second end of the spring 3 to disengage from the chain teeth and squeeze the deformation part 31 to generate an elastic restoring force.

[0043] When the zipper pull 2 ​​is pulled, the zipper pull 2 ​​engages with the driven part 5 of the spring 3 via the driving part 4, causing the second end of the spring 3 to disengage from the zipper teeth. Simultaneously, it compresses the deformation part 31 of the spring 3, causing it to deform and store elastic potential energy. When the zipper pull 2 ​​is no longer subjected to external force, the elastic potential energy of the deformation part 31 is released, and the resulting elastic restoring force pushes the zipper pull 2 ​​back to its original position, locking the zipper pull to the zipper teeth. This solves the problem of existing zipper pulls failing to automatically reset after being lifted, which can easily cause the zipper to open unexpectedly, thus improving the zipper's performance and stability.

[0044] The slider structure provided by this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0045] In one specific implementation, reference is made to... Figure 2 and Figure 4 The deformable portion 31 is a concave valley formed in the middle section of the spring piece 3; a first arch 32 is formed between the deformable portion 31 and the first end, and a second arch 33 is formed between the deformable portion 31 and the second end.

[0046] Specifically, the deformation part 31 is a downwardly concave trough formed in the middle section of the spring piece 3. The purpose of this shape is to achieve sufficient deformation capacity. The smaller the angle of the trough, the easier it is to deform, while the larger the angle, the stronger its elastic recovery force.

[0047] In conjunction with this, a first arch 32 and a second arch 33 are formed on the spring 3, which are located on both sides of the deformable part 31. The first arch 32 and the second arch 33 have parabolic cross sections to maintain the stability of the arch structure and facilitate the transmission of force.

[0048] Preferably, the included angle formed by the deformed portion 31 is in the range of 45°-70°.

[0049] Preferably, the height-to-span ratio of the first arch 32 and the second arch 33 is 0.30-0.50.

[0050] Optionally, the deformable part 31 can also be an upwardly protruding arched structure formed on the spring piece 3, the other features of which are the same as the downwardly concave valley structure described above, and will not be described again.

[0051] Based on any of the above embodiments, refer to Figure 2 The pull head base 1 is provided with a receiving cavity 12 for accommodating the deformable part 31, and there is a gap between the bottom of the receiving cavity 12 and the core plate of the pull head base 1.

[0052] Specifically, there is a certain gap between the bottom of the receiving cavity 12 and the core plate of the zipper base 1 to maintain the strength of the zipper itself. At the same time, there is a certain amount of space between the inner wall of the receiving cavity 12 and the deformable part 31 to accommodate the deformed part 31.

[0053] Furthermore, the slopes of the side walls of the receiving cavity 12 are in relation to the slope of the deformable part 31 of the shrapnel 3. The section of the receiving cavity 12 and the shrapnel 3 near the arch has a certain slope so that the shrapnel 3 can be smoothly received after deformation. The slope of the receiving cavity 12 near the fixed end of the shrapnel 3 is more vertical and steep to prevent the deformable part 31 of the shrapnel 3 from sliding out of the receiving part when subjected to force.

[0054] The pull tab and spring sheet structure provided by this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0055] Based on any of the above embodiments, refer to Figures 2 to 4 The driving part 4 includes a pull tab crossbar 21 disposed on the pull tab 2 and cooperating with the clamp part 11, and a pull tab protrusion 22 disposed on the pull tab crossbar 21; the driven part 5 includes a spring sheet hole 34 opened in the spring sheet 3, and the pull tab protrusion 22 is inserted into the spring sheet hole 34 so that when the pull tab 2 is pulled, one side of the pull tab protrusion 22 abuts against the edge of the spring sheet hole 34.

[0056] Specifically, the pull tab crossbar 21 cooperates with the clamp 11 and is rotatably disposed within the clamp 11. A spring sheet hole 34 is provided at the second end of the spring sheet 3. A pull tab protrusion 22 is provided on the side of the pull tab crossbar 21 near the spring sheet 3. The pull tab protrusion 22 is inserted into the spring sheet hole 34. During the rotation of the pull tab crossbar 21 with the pull tab, the pull tab protrusion 22 will abut against the upper edge of the spring sheet hole 34, thereby squeezing the second arch 33 of the spring sheet 3. The second arch 33 is squeezed, which drives the second end of the spring sheet 3 to disengage from the chain teeth and compresses the deformed part 31 to generate a restoring force, thereby ensuring the subsequent restoring of the spring sheet 3 and the pull tab 2.

[0057] It should be noted that the pull tab crossbar 21 is generally a rod-shaped structure, and can be made of metal or plastic. Metal materials, such as stainless steel, have good strength and durability; plastic materials, such as nylon, are lightweight and low-cost. The shape of the pull tab protrusion 22 usually matches the spring clip hole 34, allowing it to pass through the spring clip hole 34. The surface of the pull tab protrusion 22 is relatively smooth to reduce friction with the spring clip hole 34. The pull tab protrusion 22 can also be replaced by other similar protruding structures, such as hemispherical protrusions. The pull tab crossbar 21 and the pull tab 2 are usually integrally molded to ensure structural stability and strength. The pull tab protrusion 22 and the pull tab crossbar 21 can be integrally molded, or they can be fixedly connected by welding, bonding, or other methods.

[0058] Optionally, the width of the pull tab protrusion 22 is less than the width between the clamps 11 on the pull head base 1, and the width of the spring tab hole 34 is less than the width of the first arch 32 and the second arch 33 on the spring tab 3.

[0059] Furthermore, the pull tab protrusion 22 is provided with a protrusion structure 23 to prevent the pull tab protrusion 22 from disengaging from the spring tab hole 34.

[0060] Specifically, the protrusion structure 23 can engage with the edge of the spring clip hole 34 during the rotation of the pull tab 2, forming a barb-like structure to prevent the pull tab protrusion 22 from disengaging from the spring clip hole 34. The protrusion structure 23 can be hemispherical or conical, etc. The function of the protrusion structure 23 is to prevent the pull tab protrusion 22 from disengaging from the spring clip hole 34, ensuring a stable engagement between the pull tab 2 and the spring clip 3. The protrusion structure 23 can be integrally formed with the pull tab protrusion 22, or it can be fixed to the pull tab protrusion 22 by means of inlay or other methods.

[0061] Based on any of the above embodiments, refer to Figure 1 Both sides of the clamp 11 are provided with a stop 13, which is used to limit the rotation angle of the pull tab 2.

[0062] Specifically, the stop 13 is located on both sides of the jaws of the clamp 11. During the use of the pull tab 2, when it rotates to the position of the stop 13, it will be blocked, thus allowing the stop 13 to limit the rotation angle. The inclined surface of the stop 13 is set with a certain slope, and it is necessary to allow the pull tab 2 to have sufficient rotation space when rotating around the pull tab crossbar 21, so as to lift the locking pin set at the second end of the spring tab 3.

[0063] Preferably, when the lifting angle of the pull tab 2 is set to greater than or equal to 100°, pulling the pull head upward will provide a good user experience. The part of the beveled surface of the stop block 13 that contacts the pull tab 2 is a flat surface to reduce damage to the surface of the pull tab 2, such as paint chipping or scratches, when the stop block 13 contacts or collides with the pull tab 2.

[0064] In other embodiments, please refer to Figure 5 and Figure 6 Unlike the driving part 4 and driven part 5 mentioned above, the driving part 4 may also include a pull tab crossbar 21 provided on the pull tab 2 and cooperating with the clamp part 11, and a pull tab hole 24 opened in the pull tab crossbar 21; the driven part 5 includes a bend portion 35 formed on the spring piece 3, the second end of the spring piece 3 is inserted into the pull tab hole 24, and the bend portion 35 abuts against the pull tab crossbar 21.

[0065] Specifically, unlike the pull tab 2 and spring tab 3 mentioned above, the spring tab 3 no longer has a spring tab hole 34, and a bend 35 is formed at the second end of the spring tab 3. The bottom surface of the bend 35 is flat, and a pull tab hole 24 is formed on the pull tab crossbar 21 to cooperate with it, so that the second end of the spring tab 3 is inserted into the pull tab hole 24, and the bottom surface of the bend 35 abuts against the upper surface of the pull tab hole 24. This can also achieve the effect of the pull tab 2 rotating to drive the spring tab 3 to deform. The rest of the pull tab 2 and spring tab 3 are the same as described above, and will not be described again here.

[0066] It should be noted that the bend 35 of the spring 3 is a special structure of the spring 3. Its angle and shape are determined according to the structure of the pull tab crossbar 21 to ensure that the bend 35 can stably abut against the pull tab crossbar 21. The bend 35 can be formed on the spring 3 by processes such as stamping.

[0067] The implementation principle of the zipper pull structure in this application embodiment is as follows: When the zipper pull 2 ​​is pulled, the zipper pull 2 ​​engages with the spring plate hole 34 of the spring plate 3 through the zipper pull protrusion 22 of the drive part 4, causing the second end of the spring plate 3 to disengage from the zipper teeth. At the same time, it compresses the deformation part 31 of the spring plate 3, causing it to deform and store elastic potential energy. When the zipper pull 2 ​​is no longer subjected to external force, the elastic potential energy of the deformation part 31 is released, and the resulting elastic restoring force pushes the zipper pull 2 ​​back to its original position, locking the zipper pull with the zipper teeth. The receiving cavity 12 of the zipper pull base 1 provides deformation space for the deformation part 31 of the spring plate 3 and ensures the strength of the zipper pull. The stop block 13 restricts the rotation angle of the zipper pull 2, improving the safety and comfort of use. This zipper pull structure solves the problem that the existing zipper pull 2 ​​cannot automatically reset after being lifted, which easily causes the zipper to open accidentally, thus improving the performance and stability of the zipper.

[0068] This application also discloses a zipper, including a zipper pull structure and two sets of zipper strips corresponding thereto, wherein the zipper pull structure is the aforementioned zipper pull structure.

[0069] Zippers typically consist of teeth, fabric tape, and other components. Teeth are the key parts that allow the zipper to open and close; they generally have a toothed structure and can be made of metal, plastic, or other materials. The fabric tape supports the teeth and is usually made of textile fabric, possessing a certain degree of flexibility and strength.

[0070] The zipper pull mechanism works as follows: The second end of the spring clip 3 engages with the zipper teeth. When the pull tab 2 rotates, it causes the second end of the spring clip 3 to disengage from the zipper teeth, allowing the zipper pull to slide along the zipper, thus opening and closing the zipper. When the pull tab 2 is not subjected to external force, the elastic restoring force of the spring clip 3 causes the pull tab 2 to return to its original position, and the second end of the spring clip 3 engages with the zipper teeth again, locking the zipper pull to the zipper teeth.

[0071] The implementation principle of this embodiment is as follows: by adopting the above-mentioned zipper pull structure with automatic reset function, the zipper pull can automatically reset and lock with the zipper teeth during use, preventing the zipper from opening accidentally. This type of zipper improves the convenience and reliability of use, meeting users' needs for zipper functionality and stability.

[0072] 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.

[0073] The zipper pull structure and zipper provided by this utility model have been described in detail above. 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. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
