Abstract
Description
Technical Field
[0001] This utility model relates to the field of zipper technology, specifically to a zipper head anti-detachment structure. Background Technology
[0002] Zippers are widely used in various products such as clothing, bags, and tents. Traditional zippers consist of teeth, a zipper head, and a slider. The slider usually moves along the zipper head, which is convenient for pulling. However, the slider is prone to wobbling, and this wobbling can cause jamming at the connection point with the zipper head. This affects the user experience and can also cause the zipper head to shift on the zipper. Furthermore, it increases the probability of deformation or even detachment of the slider and zipper head, resulting in a less than ideal performance. Utility Model Content
[0003] The purpose of this utility model is to provide a zipper pull anti-detachment structure. This structure can further improve the detachability and flexibility of the zipper pull, making it convenient for operation and adjustment. At the same time, the zipper pull is less likely to wobble on the protrusion or even shift due to wobble, thus preventing it from getting stuck in the corresponding cavity of the protrusion and causing adverse effects on people's wearing activities. It can also effectively reduce the wear on the protrusion and the upper plate of the zipper pull, and reduce the probability of deformation or even detachment of the zipper pull due to external forces caused by unnecessary movements during wearing. This improves the structural compactness and functional versatility of this zipper pull.
[0004] The technical solution adopted by this utility model to solve the above problems is:
[0005] A zipper pull anti-detachment structure includes a zipper pull and a puller connected by a protrusion on the zipper pull. The zipper pull includes an upper chain plate and a lower chain plate, both ends of which are provided with chain grooves for zipper sliding and are detachably connected by an adjusting member. The protrusion acts on the upper chain plate. The adjusting member is located on one side of the protrusion and passes through the upper chain plate and is rotatably connected to the lower chain plate. The puller rotates on the protrusion through a connecting rod at both ends and a through groove formed between the two sets of connecting rods. The connecting rod is located between the protrusion and the adjusting member and is locked in place by a snap-fit part.
[0006] Preferably, the adjusting component is provided in multiple sets, and the connecting rods that are engaged with the adjusting component through the snap-fit part are arranged in multiple sets at intervals in the through groove of the pull head.
[0007] Preferably, the pull head is also rotatably provided with a second pull head, and the second pull head is provided with a second connecting rod and is engaged with the protrusion through a second locking part.
[0008] Preferably, the upper chain plate is provided with a connector and a through hole is provided on the connector, and the lower chain plate is provided with a connector groove adapted to the connector and a plug with a connection hole adapted to the adjustment component is provided in the connector groove. The connector and the connector groove are square in shape.
[0009] Preferably, the through hole includes a first hole and a second hole with different diameters for the adjustment member and the plug to pass through, the plug is fitted with multiple sets of rubber sleeves, and the depth of the second hole is greater than the height of the plug, and the length of the adjustment member passing through the second hole is less than the depth of the connecting hole on the plug.
[0010] Compared with the prior art, this utility model has the following advantages and effects:
[0011] This utility model relates to a zipper pull anti-slip structure. Compared to traditional zipper pull structures and their corresponding connection methods, this zipper pull features a detachable connection between the upper and lower chain plates via an adjusting element. This further improves the detachability and flexibility of the zipper pull structure. Furthermore, the connection method where the zipper pull engages with the protrusion and adjusting element via a snap-fit mechanism facilitates operation and adjustment while limiting the position of the zipper pull engaged with the protrusion. This prevents wobbling or displacement due to wobbling, which could cause the zipper pull to become stuck in the corresponding cavity of the protrusion and negatively impact the user's wearing experience. It also effectively reduces wear on the protrusion and the upper chain plate of the zipper pull, minimizing the risk of the zipper pull being pulled off due to external forces caused by unnecessary movements during wear. The reduced probability of the zipper pull shifting on the zipper effectively lowers the likelihood of deformation or even detachment due to external forces. Furthermore, the secure connection between the zipper pull and the upper zipper plate enhances the zipper pull's structural compactness and functional versatility, improving user experience while providing some protection and meeting the needs of various usage environments. Additionally, the adjustable mechanism allows for detachable connection between the upper and lower zipper plates, and the combination of several protrusions at the head end and the arc grooves on the connecting rod further improves the positional stability of the adjustable mechanism in the locking position. This enhances the connection stability between the upper and lower zipper plates and the structural stability of the zipper pull, improving the connection stability and anti-detachment effect. Figure 2For example, the top wall of the adjusting part can also be calibrated and added according to usage requirements. When the adjusting part is locked to the lower chain plate on the upper chain plate, the arrow and other marking structures on the corresponding position of the arc groove on the connecting rod can be added (or, combined with the length setting of the adjusting part and the screw depth setting corresponding to the thread hole 220, when the adjusting part is locked to the lower chain plate on the upper chain plate, the position setting of the arrow and other marking structures on its top end face is set to correspond to the position of the arc groove on the connecting rod). This facilitates the locking connection of the locking part and makes it easy to observe and adjust the looseness of the adjusting part, thereby improving the performance of the zipper head.

Detailed Implementation
[0015] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0016] See Figure 1-4 This embodiment relates to a zipper head 100 anti-detachment structure, including a zipper head 100 and a puller 3 connected by a protrusion 101 provided on the zipper head 100. The zipper head 100 includes an upper chain plate 1 and a lower chain plate 2, both ends of which are provided with chain grooves 102 for zipper sliding and are detachably connected by an adjusting member 4. The protrusion 101 acts on the upper chain plate 1. The adjusting member 4 is located on one side of the protrusion 101 and passes through the upper chain plate 1 and is rotatably connected to the lower chain plate 2. The puller 3 rotates on the protrusion 101 through a connecting rod 31 provided at both ends and a through groove 30 formed between the two sets of connecting rods 31. The connecting rod 31 is located between the protrusion 101 and the adjusting member 4 and is locked by a locking part 5.
[0017] Specifically in this embodiment, such as Figure 1 and Figure 2 The overall structural design of this type of zipper pull 100 anti-detachment structure, combined with... Figure 3 and Figure 4 As shown, the zipper head 100, which is configured as a split structure with an upper chain plate 1 and a lower chain plate 2, can be tightened and loosened by adjusting the adjusting member 4 through the threaded holes 220 corresponding to the upper chain plate 1 and the lower chain plate 2. This enables a detachable connection between the upper chain plate 1 and the lower chain plate 2, as well as a detachable connection between the zipper head 100 and the zipper through the zipper groove 102. Simultaneously, considering the structure of the protrusion 101 on the upper chain plate 1, the connecting rod 31 on the zipper head 3, and the corresponding through groove 30, and the conventional connection method, the zipper head 3 is connected by the connecting rod 31 at one end through the cavity 1010 formed between the protrusion 101 and the upper chain plate 1. This allows the zipper head 3 to move within the cavity 1010 of the protrusion 101 for easy pulling. After the zipper head 100 is positioned on the zipper, the zipper head 3 corresponding to the protrusion 101 can be... Figure 2 In the indicated state, the connecting rod 31 at the other end of the pull head 3, located outside the protrusion 101, can be positioned between the protrusion 101 and the adjusting member 4 provided on one side, and can be fitted and engaged through the locking part 5. Specifically, the corresponding locking part 5 includes a slot 1011 opened on the wall surface corresponding to the protrusion 101, several sets of protrusions 41 arranged at intervals on the outer wall of the head end of the adjusting member 4, and several sets of arc grooves 311 for matching the protrusions 41 opened on the rod body of the connecting rod 31. By adjusting the position of the pull head 3 on the protrusion 101 and pressing it, the connecting rod 31 at the corresponding end can be locked in the slot 1011 on one side of the protrusion 101. Combined with the length setting of the adjusting member 4 and the locking state of the upper chain plate 1 and the lower chain plate 2 in the threaded hole 220, the several sets of protrusions 41 on the outer wall of its head end can engage with the several sets of arc grooves 311 opened on the wall surface corresponding to the connecting rod 31. Figure 2 The sliding locking process corresponding to the position shown corresponds to the number of sliding engagements in the state. Combined with the locking process of the protrusion 41 on the arc groove 311, this allows the adjusting member 4 to have a locking position limitation effect. When pulling out, the zipper head 3 is moved to one side of the adjusting member 4 to pull it out, and the position of the zipper head 100 is adjusted during the pulling process before returning to its original position. Figure 2The initial position of the locking state shown is sufficient. Compared with the traditional zipper head 100 structure and its corresponding connection method of the upper zipper pull 3, the upper chain plate 1 and lower chain plate 2 of the zipper head 100 can be detachably connected through the adjusting member 4, which can further improve the detachability and disassembly flexibility of the zipper head 100 structure. In addition, combined with the connection method of the zipper pull 3 locking between the protrusion 101 and the adjusting member 4 through the locking part 5, it is convenient to operate and adjust, while limiting the locking position of the zipper pull 3 on the protrusion 101. It is not easy to cause shaking or displacement due to shaking, which could cause the zipper pull 3 to lock in the corresponding cavity 1010 of the protrusion 101 and have an adverse effect on people's wearing activities. It can also effectively reduce the wear and tear on the protrusion 101 and the upper chain plate 1 of the zipper head 100, and reduce the zipper pull 100 from being locked in the zipper due to external force caused by unnecessary movements during wearing. The probability of displacement is reduced, effectively decreasing the likelihood of deformation or even detachment of the zipper pull 3 and zipper head 100 under external force. Furthermore, the secure connection between the zipper pull 3 and the upper chain plate 1 of the zipper head 100 enhances the structural compactness and functional versatility of the zipper head 100, improving user experience and providing some protection to meet the needs of different usage environments. Additionally, the zipper head 100, through the adjusting member 4, facilitates a detachable connection between the upper chain plate 1 and the lower chain plate 2. Combined with the locking effect of several sets of protrusions 41 at its head end and the arc groove 311 on the connecting rod 31, the positional stability of the adjusting member 4 in the locking position is further improved. This further enhances the connection stability between the upper chain plate 1 and the lower chain plate 2, as well as the structural stability of the zipper head 100, improving the connection stability and anti-detachment effect of the zipper head 100 on the zipper. Figure 2 For example, the top wall of the adjusting part 4 can also be calibrated and added according to the usage requirements. When the adjusting part 4 is locked to the lower chain plate 2 on the upper chain plate 1, the arrow and other marking structures 42 on the upper arc groove 311 of the connecting rod 31 are calibrated and added (or, combined with the length setting of the adjusting part 4 and the screw depth setting corresponding to the thread hole 220, when the adjusting part 4 is locked to the lower chain plate 2 on the upper chain plate 1, the position setting of the arrow and other marking structures 42 on its top end face is set to correspond to the position of the upper arc groove 311 of the connecting rod 31). This makes it convenient for the locking part 5 to lock and connect, and at the same time, it is convenient to observe and adjust the looseness of the adjusting part 4, thereby improving the performance of the zipper head 100.
[0018] The adjusting member 4 is provided with multiple sets of connecting rods 31 that are engaged with the adjusting member 4 through the snap-fit part 5. These connecting rods 31 are arranged in multiple sets at intervals in the through groove 30 on the zipper head 3. Specifically, the adjusting member 4 and the connecting member on the zipper head 3 can be set in multiple sets according to the usage requirements. Combined with the multiple sets of slots 1011 opened on the connecting rods 31 in the snap-fit part 5 and the several sets of protrusions 41 circumferentially provided at the head end of the adjusting member 4, the engagement stability of the zipper head 3 on the zipper head 100 and the connection stability between the upper chain plate 1 and the lower chain plate 2 in the zipper head 100 can be further improved, thereby improving the stability and performance of this anti-drop structure of the zipper head 100.
[0019] The slider 3 is also rotatably equipped with a second slider 6. The second slider 6 is equipped with a second connecting rod 61 and is engaged with the protrusion 101 via a second locking part 50. The slider 3 can be connected to a corresponding end of the second slider 6 via the connecting rod 31 according to usage requirements. The second slider 6 can rotate on the slider 3 and engage with it. Figure 2 In the indicated state, when the zipper pull 3 is engaged between the protrusion 101 and the adjusting member 4 via the engaging part 5, the second zipper pull 6, through the second connecting rod 61 on it and the second through groove 60 formed between the second connecting rod 61 and the corresponding end connecting rod 31 on the zipper pull 3, combined with the second engaging part 50 being set as a second groove 1012 opened on the other side wall of the protrusion 101 away from the groove 1011, realizes the engagement and position limitation of the second zipper pull 6 around the zipper pull 3. The second zipper pull 6 can be selectively added as an extension structure of the zipper pull 3 according to the usage requirements, thereby facilitating the operation of pulling the zipper pull 100. Combined with the engagement process of the second zipper pull 6 after being folded on the protrusion 101 via the second engaging part 50, it is convenient to operate and does not easily affect the user experience due to the addition of the second zipper pull 6, thus meeting different usage requirements.
[0020] The upper chain plate 1 is provided with a connector 11 and a through hole 12. The lower chain plate 2 is provided with a connector slot 21 adapted to the connector 11 and a plug 22 with a connection hole 220 adapted to the adjustment component 4 is provided in the connector slot 21. The connector 11 and the connector slot 21 are square in shape. Specifically, from Figure 3 and Figure 4As can be seen, the adjusting member 4 can be inserted into the through hole 12 on the upper chain plate 1 located on the plug 11. At the same time, in conjunction with the insertion process of the plug 11 in the insertion groove 21 and the plug 22 in the through hole 12, and the rotation process of the adjusting member 4 in the connection hole 220 with a threaded hole 220 on the plug 22, the detachable connection process between the upper chain plate 1 and the lower chain plate 2 in the zipper head 100 is realized. Furthermore, the square-shaped plug 11 and insertion groove 21 can facilitate detachable connection while ensuring the stability of the relative position between the upper chain plate 1 and the lower chain plate 2. This avoids misalignment of the upper chain plate 1 and the lower chain plate 2 during installation or the need for position adjustment, further improving the convenience and efficiency of the zipper head 100 in installation, disassembly, and other corresponding operations.
[0021] The through hole 12 includes a first hole 121 and a second hole 122 with different diameters for the adjustment member 4 and the plug 22 to pass through. Multiple sets of rubber sleeves 7 are fitted onto the plug connector 11, and the depth of the second hole 122 is greater than the height of the plug 22. The length of the adjustment member 4 passing through the second hole 122 is less than the depth of the connecting hole 220 on the plug 22. Specifically, during installation, multiple sets of rubber sleeves 7 can be pre-fitted onto the plug connector 11. The specific number of rubber sleeves 7 and their corresponding upper chain plates 1 and... The corresponding spacing generated by the chain groove 102 between the lower chain plates 2 can be fitted according to the usage requirements and the zipper structure. In this state, combined with the setting that the hole depth of the second hole 122 is greater than the height of the plug 22, when the plug 11 is inserted into the insertion groove 21, the addition of the upper rubber sleeve 7 makes the plug 22 in the second hole 122 leave an appropriate gap at the lower end of the upper first hole 121. The adjusting member 4 can pass through the first hole 121 in the through hole 12 and be connected to the lower second hole 122. The plug 22 rotates within the connection hole 220 of the plug 22. When the adjusting member 4 rotates and tightens within the connection hole 220, the rubber sleeve 7 between the plug 11 and the insertion groove 21 is subjected to a certain pressure to produce appropriate deformation. When the corresponding number of rubber sleeves 7 reaches the deformation limit, making it impossible for the adjusting member 4 to continue rotating and tightening within the connection hole 220 on the plug 22, a locking state is reached (in combination with the thickness and corresponding number of rubber sleeves 7, this state is the state in which the zipper head 100 slides stably on the zipper). The above structure and the addition of rubber sleeves 7 can provide a certain buffering effect on the connection process between the upper chain plate 1 and the lower chain plate 2 in the zipper head 100. At the same time, the corresponding spacing between the upper chain groove 102 of the upper chain plate 1 and the lower chain plate 2 can be changed by appropriately increasing or decreasing the number of rubber sleeves 7. Under the premise of ensuring that the zipper head 100 can slide stably on the zipper, the usage requirements of zippers of different specifications are met, further improving the structural flexibility and applicability of the zipper head 100.
[0022] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
