A long-tail clip

Abstract

The present invention discloses a long-tail clip, which relates to the technical field of clamping tools and solves the problem of laborious opening operation. It includes a clip body and a pair of tail handles. At the front end of each tail handle, there are two pivot shaft parts located on the same axis. The pair of tail handles are symmetrically arranged on both sides of the clip body, and their pivot shaft parts are rotatably installed in the clip pieces. The installation position of the pivot shaft parts is between the position far from the clip opening part and the central position of the distance from the clip opening part to the ridge part. Pressing the ends of the pair of tail handles towards each other can make the clip opening part open by pivoting with both sides of the ridge part as the fulcrums. Compared with the prior art, the present invention changes the installation position of the front end of the tail handle, that is, changes the position of the acting point, moves the installation position of the pivot shaft part in the tail handle towards the center position of the clip piece, so as to shorten the distance between the acting point and the ridge fulcrum, lengthen the distance from the ridge fulcrum to the end of the tail handle, and reduce the force required for operating the clip opening part when opening the long-tail clip.

Description

Technical Field

[0001] The present invention relates to the technical field of clamping tools, and particularly to a long-tail clip.

Background Art

[0002] The long-tail clip is a common daily item. It is widely used not only in the financial field, but also in daily study, life and office.

[0003] The long-tail clip of the prior art generally has a clip body and a pair of tail handles for opening the clip body. The clip body is formed by bending an elastic metal plate. It has an elastic ridge in the center and two clip pieces distributed on both sides of it. When viewed from the side, it is slightly triangular, and the front end of the clip piece has a clamping mouth part. The clamping mouth part has a restoring force and is in a closed state. The tail handle is rotatably connected to the clip body through a mounting part formed on the clamping mouth part. The opening operation of the long-tail clip is as follows: abut each tail handle against both sides of the ridge, use the abutting point as a fulcrum, and open the clamping mouth part of the clip body by rotating and pressing each tail handle towards each other.

[0004] According to the lever principle in mechanics theorem for the long-tail clip of this structure, that is: power × power arm = resistance × resistance arm, its resistance: the clamping force of the clamping mouth part, that is, the restoring force; the resistance arm: the distance from the clamping mouth part to the fulcrum of the ridge, that is, the length of the clip piece; the power arm: the distance from the end of the tail handle to the fulcrum of the ridge, that is, the difference between the length of the tail handle and the resistance arm. Since the resistance arm is relatively long, a relatively large force is required to open the long-tail clip of this structure, making it more laborious in actual use.

[0005] In view of this situation, the Japanese patent publication number JP3117841U discloses a more labor-saving long-tail clip, which is formed by making the rod member for opening the clip body adjacent to the fulcrum where the clip body abuts, that is, the bearing part, to the opening part, thereby shortening the distance between the acting point and the fulcrum. The end of its rod member is still connected to the opening part, and the fulcrum moves to a position adjacent to the opening part. In other words, the resistance arm is shortened, that is, the distance from the clamping mouth part to the fulcrum is shortened; the power arm is lengthened, that is, the distance from the fulcrum to the end of the rod member is lengthened. Therefore, the force required for the opening operation of the long-tail clip is reduced.

[0006] However, in this patent, the acting force of the tail handle pressing the fulcrum is in the direction of closing the clamping mouth part, so the force required for the opening operation of the clamping mouth part will be increased. In addition, if you want to reduce the force required for the opening operation in this case, the length of the tail handle must be lengthened, which may lead to the enlargement of the long-tail clip, and its actual use effect is not ideal.

Summary of the Invention

[0007] The purpose of the present invention is to solve the problems in the prior art and to provide a long-tail ticket clip which can reduce the force required to open the clip portion while keeping the length of the tail handle unchanged.

[0009] The ticket clip body is formed by folding an elastic plate toward each other to form an elastic ridge in the center and two clips on both sides thereof, the front ends of the two clips are elastically supported to fit together to form a clamping portion for clamping an object;

[0010] and a pair of tail handles, each tail handle has two pivot shafts located on the same axis at the front end,

[0011] The pair of tail handles are symmetrically arranged on both sides of the ticket clip body, and their pivot shaft portions are rotatably installed in the clip. The installation position of the pivot shaft portions is between the center position away from the clamping mouth portion and the distance from the clamping mouth portion to the spine portion.

[Specific implementation method]

[0033] Example 1

[0034] See also Figures 1 to 3 , this embodiment includes:

[0035] A ticket clip body 1, wherein the ticket clip body 1 is formed by folding an elastic plate toward each other, and forms an elastic ridge 2 located in the center and two clips 3 distributed on both sides thereof, wherein the two clips 3 and the elastic ridge 2 are distributed in an isosceles triangle, and the clips 3 and the ridge 2 are transitioned through an arc surface, and the front ends of the two clips 3 are elastically supported by the elastic plate and are in a close fit to form a clamping portion 4 for clamping an object, and the clamping portion 4 is in a closed state at this time;

[0036] and a pair of tail handles 5, each tail handle 5 has two pivot shafts 6 located on the same axis at the front end, which are completely formed by folding a long strip of metal wire, and the two ends of the metal wire radially extend outward to form the pivot shafts 6 perpendicular to the body.

[0037] The pair of tail handles 5 are symmetrically arranged on both sides of the ticket clip body 1, and the pivot shaft 6 thereof is rotatably installed in the clip 3. The installation position of the pivot shaft 6 is between the distance from the clamping mouth 4 (i.e., not including the clamping mouth 4) to the central position of the distance from the clamping mouth 4 to the spine 2 (the center position of the clip 3), and pressing the ends of the pair of tail handles 5 toward each other can make the clamping mouth 4 open with the two sides of the spine 2 as the fulcrum. After adopting this structure, the present invention moves the installation position of the pivot shaft in the tail handle from the clamping mouth in the prior art to the center position of the clip 3, thereby shortening the distance between the action point and the fulcrum of the spine 2. When the overall length of the tail handle 5 remains unchanged, the distance of the tail handle 5 extending from the ticket clip body 1 is extended, i.e., the distance from the fulcrum of the spine 2 to its end, so as to achieve the purpose of shortening the resistance arm and extending the force arm, thereby reducing the force required for opening the clamping mouth 4 in the long-tail ticket clip, and achieving a labor-saving effect.

[0038] In order to install the tail handle 5 on the clamping piece 3, on the end surface of each clamping piece 3, there are integrally formed mounting parts 7 that are distributed in pairs and are used for inserting the pivot shaft part 6 so that the tail handle 5 is rotatably installed. The mounting part 7 is located at the central position of the distance from the clamping opening part 4 to the ridge part 2. The structure of the mounting part 7 integrally formed with the clamping piece 3 not only saves the cost of components and eliminates the problem of insufficient structural strength caused by processes such as welding and bonding, but also improves the production efficiency of the product.

[0039] In order to integrally process the mounting part 7 for fixing the tail handle 5 on the clamping piece 3, the mounting part 7 is formed by stretching and deforming on the clamping piece 3 to be bulged or sunken inward. The two ends of the mounting part 7 are connected to the clamping piece 3, and its side wall is separated from the clamping piece 3 through a cutting line. The bulged mounting part 7 or the sunken clamping piece 3 can make it misaligned with the end surface of the clamping piece 3 and form a limiting hole 8 for the pivot shaft part 6 to penetrate on the cutting line. By using the cutting line method, after the clamping piece 3 is bulged or sunken, a limiting hole 8 for the pivot shaft part 6 to penetrate can be successfully formed. At the same time, the setting of the cutting line enables the two sides of the cutting line to be separated, so as to facilitate forging or stamping processing without causing tensile surface scratches, wire bending cracks, thus ensuring the structural strength.

[0040] Specifically, the mounting part 7 is arranged in a bulged shape on the clamping piece 3 and is symmetrically distributed. The two sides of the mounting part 7 are separated from the clamping piece 3 through cutting lines. The two cutting lines are parallel and are arranged along the length direction from the clamping opening part 4 to the ridge part 2. The two ends of the cutting lines do not extend to the clamping opening part 4 and the ridge part 2. After the part between the two cuttings on the clamping piece 3 is forged or stamped, it undergoes tensile deformation to be arched or semi-circularly bulged relative to the end surface of the clamping piece 3. The bulged mounting part 7 can make it misaligned with the end surface of the clamping piece 3 and form a limiting hole 8. The pivot shaft part 6 passes through the limiting hole 8 from the cutting line. The mounting part 7 cooperates with the parts of the clamping piece 3 on its two sides to limit and fix the pivot shaft part 6 so that it can rotate freely. In this embodiment, the part of the clamping piece 3 between the two mounting parts 7 is flat and does not sink inward.

[0041] In order to lock the tail handle 5 after rotation, on the wire cutting lines on the side where the two mounting parts 7 are for the tail handle 5 to insert, there are triangular protrusions distributed towards each other. By using these triangular protrusions, after the mounting part 7 is misaligned and stretched with the clamping piece 3, clamping grooves are formed on both sides of the triangular protrusions, thereby realizing the locking of the tail handle 5 and ensuring the structural strength of the stretched and formed mounting part 7.

[0042] In order to make the installation of the pivot shaft portion 6 more firm and enhance its rotational flexibility, a support mechanism is formed on the clip 3 by concave-convex molding on one side of the installation portion 7. The support mechanism is used to wrap around the end of the pivot shaft portion 6 in a staggered manner and limit and fix it. The support mechanism and the installation portion 7 are located on the same axis. With this structural design, the acting area between the clip 3 and the pivot shaft portion 6 is increased, and the firmness of the acting point when the tail handle 5 pries the clip 3 is improved.

[0043] Specifically, the support mechanism includes a first support portion 10 located at the edge of the clip 3 and a second support portion 11 located between the first support portion 10 and the installation portion 7. The first support portion 10 is formed by stretching and deforming the clip 3 into a raised shape, and the second support portion 11 remains flush with the end face of the clip 3 without being concave. The first support portion 10 and the second support portion 11 are distributed in a staggered manner and wrap around the end of the pivot shaft portion 6.

[0044] To improve the clamping force of the clamping portion 4 on an object, a contact portion 14 for clamping and adhering to the object is provided on the clamping portion 4 of the clip 3. The contact portion 14 is bent into a circular shape, an arc shape, or a smooth planar shape that can be closed together. The contact portion 14 is used to contact or approach the surface of a document or the like.

[0045] Embodiment 2

[0046] Refer to Figure 4 and Figure 5 Omitting the components or parts that are the same as those of the long-tail clip already described in the above embodiments, the difference between this embodiment and Embodiment 1 lies only in the different structures of the installation portion and the support mechanism: In this embodiment, the installation portion 7 is not deformed and is flush with the end face of the clip 3. The installation portion 7 for installing the pivot shaft portion 6 is formed by stamping and concaveing the clip 3. Two cutting lines are distributed in parallel on the clip 3. The portion of the clip 3 between the two cutting lines is the concave portion 9. After being stamped and deformed, the concave portion 9 is misaligned with the end face of the clip 3 and forms the installation portion 7 with limit holes 8 on both sides.

[0047] Regarding the support mechanism, it includes a first support portion 10 located at the edge of the clip 3 and a second support portion 11 located between the first support portion 10 and the installation portion 7. The first support portion 10 is flush with the end face of the clip 3, and the second support portion 11 is formed by stretching and deforming the clip 3 into a concave shape. The first support portion 10 and the second support portion 11 are distributed in a staggered manner and wrap around the end of the pivot shaft portion 6. The second support portion 11 is misaligned with the end face of the clip 3 after being stamped and concave. The two ends of the second support portion 11 are connected and fixed to the clip 3, and support holes 12 for the pivot shaft portion 6 to pass through are provided on both sides.

[0048] To improve the structural strength of the second support portion 11, both sides of the second support portion 11 are connected to the clip 3 through the stretching walls 13. The support holes 12 are formed in the stretching walls 13. The stretching walls 13 and the second support portion 11 are integrally formed by stretching after stamping the clip 3.
