Description

Technical Field

[0001] The present invention relates to a card chain, an object capable of locking, buckling or closing the opening of a cloth or fabric or pocket, which has a function and use similar to that of a zipper but different in structure. Background Art

[0002] In the prior art, for an object used to connect, buckle or close the opening of a cloth or fabric or pocket, a zipper is generally adopted. A zipper is the most common item in our daily life, which has left and right chain tapes, continuously arranged teeth respectively provided on the left and right chain tapes, and a slider containing the teeth. When the slider is pulled to move on the teeth, the teeth on the left and right chain tapes can be engaged with each other or the engaged teeth can be disengaged from each other.

[0003] In recent years, someone has also invented and applied for a sliding chain. For example, the application number is 201410658506.1, and the name is "Safety Sliding Chain", which includes an upper chain body and a lower chain body. The upper chain body includes a plurality of clamping rings provided on a base cloth. The clamping ring includes two arc-shaped clamping arms connected as a whole. The lower chain body includes a long chute and a base cloth connecting seat provided at the lower end of the chute. The base cloth connecting seat is connected to the base cloth, and the upper chain body is connected to the lower chain body by clamping the chute with the clamping rings. Another example is the application number 201520762120.5, and the name is "A Safety Sliding Chain", which includes an upper chain body and a lower chain body. The upper chain body includes a plurality of clamping rings provided on an upper base cloth. The lower chain body includes connecting bodies corresponding to the clamping rings provided on a lower base cloth. There are a plurality of the connecting bodies, and each connecting body is composed of a rigid plastic connecting rod, a rigid plastic inner ball core and a rectangular elastic plastic shell. Another example is the application number 201621318537.3, and the name is "A Zipper", which includes a pair of cloth tapes and female teeth and male teeth respectively provided on one side of the cloth tapes. The feature is that the execution part of the female teeth is a hollow cylindrical structure with an axis parallel to the corresponding side cloth tape, and the execution part of the male teeth is a cylinder with an axis parallel to the corresponding side cloth tape; the cylinder is in concave-convex fit with the hollow space in the hollow cylindrical structure, and the execution part of the male teeth can be embedded into the gap formed by the hollow spaces of two adjacent execution parts of the female teeth to form a combined lock. The biggest feature of the above sliding chain is that its female teeth (clamping rings) always clamp the male teeth (connecting bodies), that is, the male teeth slide in the channel formed by the female teeth and will not break away, otherwise it cannot play the role of sliding connection. Summary of the Invention

[0004] Based on existing zippers and sliders, the present invention attempts to develop a new type of snap chain product. The snap chain is still used for fastening openings such as pockets, allowing users to be as short in the process and show personality as when using traditional frog buttons or buttons, and also giving people a feeling of stability.

[0005] The snap chain includes a first chain band and a second chain band. Several female chain teeth arranged at intervals left and right along the axial direction are provided on the first chain band, and several male chain teeth arranged at intervals left and right along the axial direction are provided on the second chain band. It is characterized in that a female tooth cavity extending along the axial direction is arranged in the female chain teeth, and a left cavity opening communicating with the female tooth cavity is provided on the left side edge in the axial direction of the female chain teeth; there is a first spacing between the female chain teeth arranged at intervals front and back that can accommodate the male chain teeth, and a second spacing between the male chain teeth arranged at intervals front and back that can accommodate the female chain teeth; in the first arrangement, several of the female chain teeth and male chain teeth can be queued and arranged alternately using the second spacing and the first spacing respectively, and in the second arrangement, the male chain teeth use the first spacing as a turning space, and at least the right end tooth body of the male chain teeth can be inserted into the female tooth cavity along the axial direction through the left cavity opening of the female chain teeth.

[0006] Among them, the first chain band and the second chain band are basic fabrics for connecting the female chain teeth and the male chain teeth, and can be long strip-shaped fabrics extending in the axial direction. The fabric can be a cloth fabric, a plastic film, a leather-like material, etc. The female chain teeth and the male chain teeth can be provided on the side edge parts of the first chain band and the second chain band, or can be provided at a certain distance from the edge. Secondly, the female chain teeth and the male chain teeth can be connected to the first chain band and the second chain band by injection molding, or can be sewn to the first chain band and the second chain band by sewing, or when the female chain teeth and the male chain teeth are made of metal, they can be bite-connected to the first chain band and the second chain band in the same way as traditional metal zippers.

[0007] In addition, the female chain teeth can be connected to the first chain band through a female tooth connection handle located inside it. The female chain teeth and the female tooth connection handle are integrally formed. In fact, the female tooth connection handle is an intermediate transition connection body between the female chain teeth and the first chain band; and the male chain teeth can be directly connected to the first chain band, or the inner side of the male chain teeth can be connected to the first chain band through a male tooth connection handle. The male chain teeth and the male tooth connection handle are integrally formed. In fact, the male tooth connection handle is an intermediate transition connection body between the male chain teeth and the second chain band.

[0008] Among them, when the male chain teeth are inserted into the female tooth cavity along the axial direction from left to right, either all of the male chain teeth can be inserted into the female tooth cavity, or part of the male chain teeth, that is, only the right end tooth body of the male chain teeth, can be inserted into the female tooth cavity to form a snap connection.

[0009] According to the above solution, it can be found that its beneficial technical effects are as follows. First, due to the setting of the first spacing and the second spacing, the female chain teeth can move into the second spacing and of course can also be separated from each other, and the male chain teeth can move into the first spacing and of course can also be separated from each other. The female chain teeth and the male chain teeth can be arranged in a staggered queue to form the first combination arrangement. Second, on the basis of the first arrangement, the male chain teeth use the first spacing as a rotation space, and the male chain teeth can be inserted into the female tooth cavity so that a clamping connection is formed between the first chain belt and the second chain belt to achieve the second arrangement. Conversely, letting the male chain teeth axially retreat from the female tooth cavity in the reverse direction can release the clamping connection, with a short stroke and simple implementation.

[0010] A further technical solution can also be that the left cavity opening of the female tooth cavity has an inclined first guiding surface, which is convenient for guiding the head of the right end tooth body of the male chain tooth. The inclination angle of the first guiding surface is generally about 45°.

[0011] A further technical solution can also be that the head of the right end tooth body of the male chain tooth has an inclined second guiding surface, which is convenient for guiding the head of the right end tooth body of the male chain tooth. The inclination angle of the second guiding surface is generally about 45°.

[0012] In the solution of forming the male chain teeth being partially inserted into the female tooth cavity axially from left to right, there are at least two ways to choose:

[0013] First, set the depth of the female tooth cavity to be less than the length of the male chain teeth and let the male chain teeth be only partially inserted and cannot pass through the right end of the female tooth cavity;

[0014] Second, set the diameter of the left cavity opening of the female chain teeth to be less than the outer diameter of the left end of the male chain teeth, so that the male chain teeth can be inserted into the female tooth cavity but cannot pass through.

[0015] Regarding the structure of the axial right side of the female chain teeth, there are at least two structures to choose:

[0016] First, a right cavity opening communicating with the female tooth cavity is provided on the axial right side of the female chain teeth, and the diameter of the right cavity opening is less than the outer diameter of the left end of the male chain teeth. This can prevent the left end of the male chain teeth from being inserted into the female tooth cavity through the right cavity opening in the left direction, resulting in misoperation.

[0017] Second, no cavity opening communicating with the female tooth cavity is provided on the axial right side of the female chain teeth.

[0018] A further technical solution may also be that the inner side of the female chain tooth is connected to the first chain belt through a female tooth connecting handle.

[0019] A further technical solution may also be that an outer opening facing outward is provided on the cavity wall of the female tooth cavity, and the outer opening penetrates at least to the left axial end of the female chain tooth, and the male chain tooth cannot escape from the female tooth cavity through the outer opening.

[0020] A further technical solution may also be that the male chain tooth is directly connected to the first chain belt, and when the male chain tooth is inserted into the female tooth cavity, the first chain belt also penetrates into the outer opening accordingly.

[0021] A further technical solution may also be that the inner side of the male chain tooth is connected to the first chain belt through a male tooth connecting handle, and when the male chain tooth is inserted into the female tooth cavity, the male tooth connecting handle also penetrates into the outer opening accordingly.

[0022] A further technical solution may also be that a stop mechanism is provided at least at a common end of the first chain belt and the second chain belt, and the stop mechanism includes a long strip groove extending axially and a positioning post passing through the long strip groove. The positioning post is inserted into the long strip groove, and the positioning post and the long strip groove are respectively arranged on the first chain belt and the second chain belt.

[0023] A further technical solution may also be that a locking hook capable of bending and deforming is provided at a position near one end of the long strip groove, and the locking hook and the groove wall body at this end of the long strip groove jointly form a positioning ring. When the positioning post moves axially in the long strip groove, it can cross the locking hook and be limited in the positioning ring.

[0024] The present invention also provides a product, including a cloth-like material, characterized in that the first chain belt and the second chain belt of the snap chain are combined with two opposite parts at the opening of the cloth-like material for snap-connecting or opening the two opposite parts. Among them, the product can be clothing, small luggage, etc.

[0025] Due to the above characteristics and advantages of the present invention, it can be applied to snap chain products featuring a snap-connection structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following further describes the structure of the chain - locking 100 applying the technical solution of the present invention with reference to the accompanying drawings. The present invention provides a new chain - locking product. The chain - locking 100 is used for locking openings such as pockets, enabling the user to be short - traveled and show personality like using traditional frog buttons or buttons, and also giving people a feeling of stability.

[0036] The chain - locking 100 of the present invention is applied to an article, such as clothing or a small luggage, etc. The clothing or small luggage includes a pocket formed by a cloth - like material, and the chain - locking 100 is arranged on the pocket. The chain - locking 100 includes a first chain belt 1 and a second chain belt 2. The first chain belt 1 and the second chain belt 2 are respectively connected to two opposite parts of the pocket mouth part, and the chain - locking 100 is used for clamping or opening the two opposite parts. The following details the specific structure of the chain - locking 100 as follows.

[0037] As Figures 1 to 7As shown, several female chain teeth 11 arranged at intervals left and right along the axis are provided on the first chain belt 1, and several male chain teeth 21 arranged at intervals left and right along the axis are provided on the second chain belt 2. The male chain teeth 21 are columnar. A female tooth cavity 12 extending along the axis is arranged in the female chain teeth 11, and a left cavity opening 121 communicating with the female tooth cavity 12 is provided on the left side edge in the axis of the female chain teeth 11. There is a first spacing Y1 between the female chain teeth 11 arranged at intervals front and back that can accommodate the male chain teeth 21, and a second spacing X2 between the male chain teeth 21 arranged at intervals front and back that can accommodate the female chain teeth 11. In the first arrangement, several of the female chain teeth 11 and male chain teeth 21 can be arranged in an interlaced queue respectively using the second spacing X2 and the first spacing Y1. In the second arrangement, the male chain teeth 21 use the first spacing Y1 as a turning space, and at least the right end tooth body 212 of the male chain teeth 21 can be inserted into the female tooth cavity 12 along the axis through the left cavity opening 121 of the female chain teeth 11.

[0038] In the above solution, as Figure 1 shown, the length of the male chain teeth 21 in the axis is Y2, and the spacing in the axis between the female chain teeth 11 arranged at intervals front and back is the first spacing Y1. The first spacing Y1 is greater than Y2, so that the first spacing Y1 can accommodate the male chain teeth 21 to extend in. Secondly, the length of the female chain teeth 11 in the axis is X1, and the spacing in the axis between the male chain teeth 21 arranged at intervals front and back is the second spacing X2. The second spacing X2 is greater than X1, so that the second spacing X2 can accommodate the female chain teeth 11 to extend in.

[0039] As Figure 2 shown, several of the female chain teeth 11 and male chain teeth 21 are arranged in an interlaced queue respectively using the second spacing X2 and the first spacing Y1 to form the first arrangement; as Figure 3 shown, on the Figure 2 basis, the male chain teeth 21 use the condition of having been moved into the first spacing Y1, use the first spacing Y1 as a turning space, and are inserted into the female tooth cavity 12 along the axis through the left cavity opening 121 of the female chain teeth 11 to form the clamping connection between the male chain teeth 21 and the female chain teeth 11, that is, to form the second arrangement. When the male chain teeth 21 are withdrawn from the female tooth cavity 12 of the female chain teeth 11, the male chain teeth 21 and the female chain teeth 11 can be separated again to release the clamping connection, with a short stroke and simple implementation.

[0040] Among them, as Figures 1 to 3As shown, the first chain belt 1 and the second chain belt 2 are strip-shaped fabrics extending in the axial direction and are base fabrics for connecting the female chain teeth 11 and the male chain teeth 21. The fabric can be a cloth fabric, a plastic film, a leather-like material, or the like. The female chain teeth 11 and the male chain teeth 21 can be provided at the side edge portions of the first chain belt 1 and the second chain belt 2, and in another embodiment, they can also be provided at a position at a certain distance from the edge.

[0041] As Figure 4a , Figure 4b shown, a female tooth connecting handle 13 is provided inside the female chain tooth 11. When the female chain tooth 11 and the female tooth connecting handle 13 are integrally injection-molded, they are simultaneously injection-connected to the side edge position of the first chain belt 1. In fact, the female tooth connecting handle is an intermediate transitional connecting body between the female chain tooth 11 and the first chain belt 1. In other embodiments, the female chain tooth 11 is sewn to the first chain belt 1 through the female tooth connecting handle 13 and a sewing thread, or even the female chain tooth 11 and the first chain belt 1 are integrally injection-molded. For example, when the female chain tooth 11 and the first chain belt 1 are both made of soft plastic material, it can be manufactured by injection molding and is also convenient for use.

[0042] As Figure 4a shown, the male chain tooth 21 is directly cast-connected to the side edge position of the second chain belt 2 by an injection molding method, and the edge of the second chain belt 2 extends into the inner core of the male chain tooth 21. In other embodiments, as Figure 4b shown, a male tooth connecting handle 23 can also be provided inside the male chain tooth 21. When the male chain tooth 21 and the male tooth connecting handle 23 are integrally injection-molded, they are simultaneously injection-connected to the side edge position of the second chain belt 2. In fact, the male tooth connecting handle 23 is an intermediate transitional connecting body between the male chain tooth 21 and the second chain belt 2. Or even the male chain tooth 21 and the second chain belt 2 are integrally injection-molded. For example, when the male chain tooth 21 and the second chain belt 2 are both made of soft plastic material, it can be manufactured by injection molding and is also convenient for use.

[0043] Among them, as Figure 6 described, the female tooth cavity 12 of the female chain tooth 11 is arranged axially, and it has a left cavity opening 121 and a right cavity opening 122. In the present embodiment, it is allowed that the male chain tooth 21 moves to the right and inserts into the female tooth cavity 12 of the female chain tooth 11 from the left cavity opening 121 of the female tooth cavity 12. But it is preferably not to continue moving to the right and passing out from the right cavity opening 122, or moving to the left and inserting into the female tooth cavity 12 of the left female chain tooth from the right cavity opening 122 of the left female chain tooth; in order to reduce the occurrence of this situation, there are several solutions:

[0044] First, make the diameter of the right cavity opening 122 smaller than the outer diameter of the left end portion 211 of the male chain tooth 21. This can prevent the left end portion 211 of the male chain tooth 21 from being reversely inserted into the left female chain tooth through the right cavity opening 122 of the left female chain tooth when moving leftward, thus avoiding misoperation.

[0045] Second, make it possible to close and cancel the right cavity opening 122 of the female tooth cavity 12 so that the female tooth cavity 12 is barrel-shaped with a bottom wall. This can directly prevent the male chain tooth 21 from passing through the bottom wall of the female tooth cavity 12 and continuing to move rightward, and also prevent the male chain tooth 21 from moving leftward and inserting into the female tooth cavity 12 of the left female chain tooth.

[0046] Third, make the outer diameter of the left end portion 211 of the male chain tooth 21 larger than the diameter of the right cavity opening 122 of the left female chain tooth.

[0047] To improve the smoothness of inserting the male chain tooth 21 into the female tooth cavity 12, the left cavity opening 121 of the female tooth cavity 12 has an inclined first guiding surface, which is convenient for guiding the head of the right end tooth body 212 of the male chain tooth 21. The inclination angle of the first guiding surface is generally about 45°. A further technical solution can also be that the head of the right end tooth body 212 of the male chain tooth 21 has an inclined second guiding surface, which is convenient for guiding the head of the right end tooth body 212 of the male chain tooth 21.

[0048] In the solution of forming the male chain tooth 21 partially inserted into the female tooth cavity 12 along the axial direction from left to right, there are at least two ways to choose:

[0049] First, set the depth of the female tooth cavity 12 to be smaller than the length of the male chain tooth 21 and make the male chain tooth 21 unable to pass through the right end portion 212 of the female tooth cavity 12

[0050] Second, as Figure 6 shown, make the left end portion 211 of the male chain tooth 21 be trumpet-shaped, and set the diameter of the left cavity opening 121 of the female chain tooth 11 to be smaller than the outer diameter of the left end portion 211 of the male chain tooth 21.

[0051] A further technical solution can also be that, as Figure 7 shown, the male chain tooth 21 is not columnar but L-shaped, and the right end tooth body 212 of the male chain tooth 21 can be inserted into the female tooth cavity 12 along the axial direction through the left cavity opening 121 of the female chain tooth 11. To prevent the right end tooth body 212 of the male chain tooth 21 from easily disengaging from the female tooth cavity 12, barbs can also be provided at the top end of the right end tooth body 212 of the male chain tooth 21 to hook the side wall of the female tooth cavity 12.

[0052] In the chain-locking structure where the male chain tooth 21 is a cylindrical structure, a further technical solution may be that an outer opening 14 facing outward is provided on the cavity wall of the female tooth cavity 12, and the outer opening 14 penetrates at least to the left axial end of the female chain tooth 11. When the male chain tooth 21 is inserted into the female tooth cavity 12, the male chain tooth 21 cannot escape from the female tooth cavity 12 through the outer opening 14. When the male chain tooth 21 is directly connected to the first chain belt 1, the first chain belt 1 also penetrates into the outer opening 14; when the inner side of the male chain tooth 21 is connected to the first chain belt 1 through a male tooth connecting handle 23, the male tooth connecting handle also penetrates into the outer opening 14.

[0053] A further technical solution may also be that, as Figure 1 , Figures 1a to 3 shown, stop mechanisms are respectively provided at the two common ends of the zipper 100. The stop mechanism includes a long slot 41 extending axially and a positioning post 42 passing through the long slot 41. The positioning post 42 is in a T shape. The positioning post 42 is inserted into the long slot 41, and the long slot 41 and the positioning post 42 are respectively arranged on the first chain belt 1 and the second chain belt 2. A locking hook 411 capable of bending and deforming is provided at a position near one end of the long slot 41. The locking hook 411 and the groove wall body at this end of the long slot 41 together form a positioning ring 412. When the positioning post 42 moves axially in the long slot 41, it can cross the locking hook 411 and be limited in the positioning ring 412. After the stop mechanisms at the upper and lower ends are positioned in this way, it is convenient to engage the male chain tooth 21 and the female chain tooth 11.

[0054] A further technical solution may also be that, as Figure 5 shown, the stop mechanism is provided at one end of the chain-locking structure. Only the positioning ring 412 is provided at one end of the first chain belt 1. Correspondingly, the positioning post 42 is provided at one end of the second chain belt 2. The positioning post 42 is inserted into the positioning ring 412 like a button to position one end of the chain 100.
