Description

Technical Field

[0001] The present invention relates to the technical field of zipper repair tools, and particularly to a zipper repair pliers. Background Art

[0002] As a commonly used accessory for clothing and luggage, a zipper has the advantages of convenient connection and adjustability. However, during the production and use of zippers, the slider may be deformed or some of the chain teeth may be damaged. These two situations generally cause the following problems: one is that the slider is stuck and cannot be pulled; the other is that the slider can be pulled back and forth but a pair of chain teeth cannot be engaged together. If the entire product is discarded after the zipper has problems, it is obviously a waste. Replacing the slider or chain teeth requires professional sewing skills and cannot solve the current urgent problem. At this time, if the zipper can be repaired emergently, it can well solve people's problems. Summary of the Invention

[0003] In order to solve the problems that the slider of the zipper is stuck or the chain teeth cannot be engaged during production or life, the present invention provides a zipper repair pliers, which includes a first handle and a second handle. It is characterized in that a chain seat is arranged at the front end of the first handle, and a chain core is arranged at the front end of the second handle. When the first handle and the second handle rotate, they can bring the chain seat and the chain core together or separate them. The chain core includes a columnar core column. The chain seat includes a bottom plate, and a pair of vertical walls, namely a left vertical wall and a right vertical wall, which are respectively arranged on both sides of the bottom plate. The left vertical wall is bent and includes a left horizontal plate and a left inclined plate. The right vertical wall is bent and includes a right horizontal plate and a right inclined plate. The left vertical wall and the right vertical wall are arranged in a left-right mirror image. At the tops of the left inclined plate and the right inclined plate, a left wing part and a right wing part extending towards each other are respectively arranged. The bottom plate, the left vertical wall, the right vertical wall, the left wing part and the right wing part define a chain tooth channel. The left horizontal plate and the right horizontal plate are arranged in parallel to form the meshing section of the chain tooth channel. The left inclined plate and the right inclined plate are arranged in a flared shape opening outwards to form the bifurcated section of the chain tooth channel. The left wing part, the right wing part, the left horizontal plate and the right horizontal plate define the upper opening of the chain tooth channel. Looking down from top to bottom, the width of the upper opening at the position between the left horizontal plate and the right horizontal plate in the left-right direction is not greater than the width of the upper opening at the position between the left wing part and the right wing part. A pair of chain tooth tapes of the zipper can enter the chain tooth channel from the upper opening. Driven by the second handle, the core column of the chain core can be inserted into the bifurcated section of the chain tooth channel from the upper opening at the position between the left wing part and the right wing part. The core column can separate a pair of chain tooth tapes and push at least part of the chain tooth tapes under the left wing part and the right wing part. The gap between the core column and the left wing part and the right wing part is smaller than the width of the chain tooth tape.

[0004] Among them, the chain seat is a component that can move back and forth as the first handle rotates. The bottom plate, left vertical wall, right vertical wall, left wing part, and right wing part of the chain seat form a base that can support a pair of chain tooth tapes. In order for the pair of chain tooth tapes to fall into and move back and forth in the chain tooth channel defined by the chain seat, the chain seat includes not only an upper opening defined by the left wing part, right wing part, left horizontal plate, and right horizontal plate, but also a front opening defined by the bottom plate, left vertical wall, and right vertical wall at the front, and a rear opening defined by the bottom plate, left vertical wall, right vertical wall, left wing part, and right wing part at the rear.

[0005] Among them, the chain core is a component that can move back and forth as the second handle rotates. It includes a vertically arranged core column and the upper baffle and front baffle mentioned below. When the chain core is separated from the chain seat, a pair of chain tooth tapes can fall into the chain tooth channel through the upper opening; when the chain core is combined with the chain seat, the core column of the chain core can not only separate a pair of chain tooth tapes, but also cooperate with the left wing part and right wing part to limit the chain tooth tapes to prevent them from slipping out.

[0006] Among them, the core column is a columnar component that can be vertically inserted into the chain tooth channel. To better guide the chain tooth tapes, in terms of cross-section, the front end of the core column facing the meshing section is provided with a chamfer. When the core column is inserted into the bifurcation section of the chain tooth channel, the core column forms a diversion island in the bifurcation section, and the chain tooth channel forms two branch channels that can allow the chain tooth tapes to pass through in the bifurcation section.

[0007] Among them, the upper opening is an opening defined by the left wing part, right wing part, left horizontal plate, and right horizontal plate. The opening edges are respectively the inner edges of the left wing part and right wing part, and the upper edges of the left horizontal plate and right horizontal plate. In order to place a pair of chain tooth tapes into the chain tooth channel, the left wing part and right wing part are also arranged symmetrically left and right. The left wing part and right wing part extend inward but do not exceed the vertical plane where the left horizontal plate and right horizontal plate are located, so as to ensure that the width of the upper opening between the left horizontal plate and right horizontal plate is not greater than the width of the upper opening between the left wing part and right wing part.

[0008] According to the above technical solution, compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0009] First, the chain seat and chain core are designed separately and connected and controlled by the first handle and the second handle, which can easily place the chain seat at different positions inside different styles of clothing or luggage, realizing local repair of the zipper. It not only effectively reduces the installation and operation difficulty, but also well solves the problems of damage to the original pull head of the zipper or local damage to the chain teeth.

[0010] Second, a chain seat with an upper opening that allows a pair of chain tooth tapes to be easily placed into the chain tooth channel through the upper opening, and then inserting the core column of the chain core can separate the pair of chain tooth tapes. The diversion channel formed by the core column, the bottom plate, the left vertical wall, the right vertical wall, the left wing part and the right wing part can not only well limit a pair of chain teeth from disengaging, but also guide the movement of the chain tooth tapes to achieve separation or engagement.

[0011] A further technical solution may also be that a groove is provided on the bottom plate, and a positioning rib is provided at the bottom of the core column. When the chain seat is combined with the chain core, the positioning rib portion of the core column can be inserted into the groove.

[0012] In order to further limit the chain tooth tape and reduce the risk of the chain tooth tape disengaging from the gap between the left wing part, the right wing part and the core column, the chain core further includes an upper baffle plate. The upper baffle plate is connected to the upper end of the core column and extends radially outward. When the chain seat is combined with the chain core, the upper baffle plate falls into the upper opening at the position between the left wing part and the right wing part, and at least part of the upper baffle plate falls into the chain tooth channel. The bottom surface of the upper baffle plate is not higher than the bottom surfaces of the left wing part and the right wing part. The upper baffle plate can further fill the gap between the left wing part, the right wing part and the core column, reducing the risk of the chain tooth tape disengaging.

[0013] If the upper opening corresponding to the meshing section remains open, when repairing a pair of chain tooth tapes, the chain tooth tapes will easily slide out from the upper opening corresponding to the meshing section, and it is necessary to press the bottom plate of the chain seat against the chain tooth tapes when pulling the repair pliers. To solve this problem, the chain core further includes a front baffle plate. The front baffle plate is connected to the front end of the upper baffle plate, and at least part of the front baffle plate extends forward into the upper opening at the position between the left cross plate and the right cross plate. The front baffle plate can well limit the chain tooth tapes, enabling a pair of chain tooth tapes to better complete the meshing action and sliding in the meshing section.

[0014] A further technical solution may also be that it further includes a locking rod. The locking rod is rotatably connected to the first handle or the second handle. When the chain seat is combined with the chain core, the locking rod can lock and connect the first handle and the second handle.

[0015] Due to the above characteristics and advantages of the present invention, it can be applied to a zipper repair pliers. Description of the Drawings

[0020] The following further describes the structure of the zipper repair pliers applying the technical solution of the present invention with reference to the accompanying drawings.

[0021] Except for those clearly stated as equivalent or alternative implementation manners, the various implementation detail solutions disclosed below can be selectively applied or combined and applied in one embodiment even if there is no direct association or synergy in terms of functions.

[0022] As Figures 1 to 4 shown, the present invention provides a zipper repair pliers, including a first handle 11, a second handle 12 and a connecting shaft 13. The first handle 11 and the second handle 12 are rotatably connected together through the connecting shaft 13; a chain base 2 is provided at the front end of the first handle 11, and a chain core 3 is provided at the front end of the second handle 12. When the first handle 11 and the second handle 12 rotate, they can bring the chain base 2 and the chain core 3 together or separate them. In this embodiment, the chain base 2 and the chain core 3 are fixedly connected to the front ends of the first handle 11 and the second handle 12 through connecting screws. In other equivalent implementation manners, the chain base 2 and the chain core 3 can also be integrally processed directly at the front ends of the first handle 11 and the second handle 12.

[0023] The chain core 3 includes a columnar core column 31. The chain base 2 includes a bottom plate 4, and a pair of vertical walls, namely a left vertical wall 5 and a right vertical wall 6, which are separately arranged on both sides of the bottom plate 4. The left vertical wall 5 is bent and includes a left horizontal plate 51 and a left inclined plate 52. The right vertical wall 6 is bent and includes a right horizontal plate 61 and a right inclined plate 62. The left vertical wall 5 and the right vertical wall 6 are arranged in left-right mirror symmetry. At the tops of the left inclined plate 52 and the right inclined plate 62, there are respectively provided a left wing portion 71 and a right wing portion 72 extending in a direction approaching each other. The bottom plate 4, the left vertical wall 5, the right vertical wall 6, the left wing portion 71 and the right wing portion 72 define a tooth channel 100. The left horizontal plate 51 and the right horizontal plate 61 are arranged in parallel to form an engagement section 110 of the tooth channel 100. The left inclined plate 52 and the right inclined plate 62 are arranged in a flared shape opening outwards to form a bifurcation section 120 of the tooth channel 100. The left wing portion 71, the right wing portion 72, the left horizontal plate 51 and the right horizontal plate 61 define an upper opening 101 of the tooth channel 100. Looking down from top to bottom, the width of the upper opening 101 at a position between the left horizontal plate 51 and the right horizontal plate 61 in the left-right direction is not greater than the width of the upper opening 101 at a position between the left wing portion 71 and the right wing portion 72. A pair of tooth tapes of the zipper can enter the tooth channel 100 from the upper opening 101. Driven by the second handle 12, the core column 31 of the chain core 3 can be inserted into the bifurcation section 120 of the tooth channel 100 from the upper opening 101 at a position between the left wing portion 71 and the right wing portion 72. The core column 31 can separate a pair of tooth tapes and push at least part of the tooth tapes under the left wing portion 71 and the right wing portion 72. The gap between the core column 31 and the left wing portion 71 and the right wing portion 72 is smaller than the width of the tooth tape. The chain base 2 and the chain core 3 are designed separately and are connected and controlled by the first handle 11 and the second handle 12, which can easily place the chain base 2 at different positions inside different styles of clothing or luggage, so as to realize the repair of the zipper.

[0024] Such as Figure 3As shown, the bottom plate 4 of the chain seat 2 is the main supporting component, which is connected to both the first handle 11 and the left vertical wall 5 and the right vertical wall 6. In addition to the upper opening 101 defined by the left vertical wall 5, the right vertical wall 6, the left wing portion 71 and the right wing portion 72, the chain seat 2 further includes a front opening 102 defined by the bottom plate 4, the left vertical wall 5 and the right vertical wall 6 at the front upper part, and a rear opening 103 defined by the bottom plate 4, the left vertical wall 5, the right vertical wall 6, the left wing portion 71 and the right wing portion 72 at the rear. The front opening 102 communicates with the meshing section 110, and the rear opening 103 communicates with the bifurcated section 102, so that after the chain tooth belt falls into the chain tooth channel 100, it can still move back and forth in the front-rear direction. Among them, the distance between the left cross plate 51 and the right cross plate 61 (i.e., the width of the meshing section 110) is set to the width that allows a pair of chain teeth to mesh, while the distance between the left inclined plate 52 and the right inclined plate 62 (i.e., the width of the bifurcated section 120) gradually increases from the inside to the outside. Since the distance between the left cross plate 51 and the right cross plate 61 corresponds to the minimum width of the upper opening 101, the left wing portion 71 and the right wing portion 72 extend inward but do not exceed the vertical plane where the left cross plate 51 and the right cross plate 61 are located, which allows a pair of chain tooth belts to enter the chain tooth channel 100 through the upper opening 101.

[0025] As Figure 4 shown, the chain core 3 is a columnar component that can move back and forth as the second handle 12 rotates. When the chain core 3 is separated from the chain seat 2, the core column 31 moves away from the chain tooth channel 100, and a pair of chain tooth belts can fall into the chain tooth channel 100 through the upper opening 101; when the chain core 3 is combined with the chain seat 2, the core column 31 is inserted into the chain tooth channel 100, which can not only separate a pair of chain tooth belts, but also cooperate with the left wing portion 71 and the right wing portion 72 to limit the chain tooth belts to prevent them from slipping out. In order to better guide the chain tooth belts, in terms of cross-section, the core column 31 is provided with a chamfer at the front end facing the meshing section 110. When the core column 31 is inserted into the bifurcated section 120 of the chain tooth channel 100, the core column 31 forms a diversion island in the bifurcated section 120, and the chain tooth channel 100 forms two branch channels that allow the chain tooth belts to pass through in the bifurcated section 120. This can not only well limit a pair of chain teeth from slipping out, but also guide the movement of the chain tooth belts to enable them to be separated or meshed.

[0026] A further technical solution can also be that a groove 41 is provided on the bottom plate 4, and a positioning rib 32 is provided at the bottom of the core column 31. When the chain seat 2 is combined with the chain core 3, the positioning rib 32 of the core column 31 can be inserted into the groove 41. This can reduce the displacement of the core column 31 and stably connect the core column 31 to the bottom plate 4.

[0027] To further define the tooth chain belt and reduce the risk of the tooth chain belt slipping out from the gap between the left wing portion 71, the right wing portion 72 and the core column 31, an upper baffle 33 is further connected to the upper end portion of the chain core 3. The upper baffle 33 is connected to the upper end portion of the core column 31 and extends radially outward. When the chain base 2 is combined with the chain core 3, the upper baffle 33 falls into the upper opening 101 at the position between the left wing portion 71 and the right wing portion 72, and at least a part of the upper baffle 33 falls into the tooth chain channel 100. The bottom surface of the upper baffle 33 is not higher than the bottom surfaces of the left wing portion 71 and the right wing portion 72. In this way, the upper baffle 33 can further fill the gap between the left wing portion 71, the right wing portion 72 and the core column 31, reducing the risk of the tooth chain belt slipping out.

[0028] Furthermore, the chain core 3 further includes a front baffle 34. The front baffle 34 is connected to the front end of the upper baffle 33, and at least a part of the front baffle 34 extends forward into the upper opening 101 at the position between the left cross plate 51 and the right cross plate 61. The front baffle 34 can well define the tooth chain belt, enabling a pair of tooth chain belts to better complete the meshing action and sliding in the meshing section 110.

[0029] A further technical solution may also be that the pliers body further includes a locking rod 8. The locking rod 8 is rotatably connected to the first handle 11 or the second handle 12. When the chain base 2 is combined with the chain core 3, rotating the locking rod 8 can lock and connect the first handle 11 and the second handle 12.
