Description

Technical Field

[0001] This utility model relates to the field of office stationery technology, and in particular to a novel swallowtail clip. Background Technology

[0002] In daily office work, study, and handicrafts, binder clips are a common clamping tool widely used to hold various items such as paper, documents, and fabric. A binder clip is mainly composed of bent metal wire forming two symmetrical clamping arms, a base connecting the arms, and a pair of handles on the arms. Items such as paper, documents, and fabric are clamped by pressing the handles. However, traditional binder clips have a relatively fixed length, which cannot provide an effective clamping area when clamping larger or oddly shaped items, causing the items to swing within the clamping surface. Therefore, a new type of binder clip has been invented to address the shortcomings of traditional binder clips in terms of flexibility and adaptability. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a new type of dovetail clip.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A novel dovetail clip includes a clip body and bases symmetrically arranged on both sides of the clip body. The top of the clip body is symmetrically provided with a first sliding groove, and the bottom inner side of the clip body is fixedly connected with a second reinforcing rib. A second guide rail is fixedly connected to the second reinforcing rib. The base is provided with a first guide rail that matches the first sliding groove and a second sliding groove that matches the second guide rail. The base is slidably connected to both sides of the clip body through the first guide rail, the first sliding groove, the second sliding groove, and the second guide rail. A first magnetic block is provided at the beginning of the first guide rail, and a second magnetic block is provided at the end of the first sliding groove. The first magnetic block and the second magnetic block are connected. A first curved part is fixedly connected to the base, and a clamping arm is connected inside the first curved part. A clamping part is provided at the upper end of the clamping arm.

[0006] Preferably, a nut is provided on one side of the first curved portion, and the nut is connected to the clamping arm that passes through the first curved portion.

[0007] Preferably, the clamp body has several connecting grooves on both sides, and the base has connecting strips corresponding to the connecting grooves on its inner side, the connecting strips being fitted into the connecting grooves.

[0008] Preferably, the cross-sectional shape of the connecting groove is dovetail-shaped, and the cross-sectional shape of the connecting strip matches the connecting groove.

[0009] Preferably, the bottom of the clamp is fixedly connected to a second curved portion, and a spring is provided inside the second curved portion, with both ends of the spring fixed to the inner side of the clamp arm.

[0010] Preferably, a first reinforcing rib is provided on one side of the first groove, and the first reinforcing rib is fixedly connected to the clamp.

[0011] Preferably, the outer side of the clamping part is provided with anti-slip texture.

[0012] The beneficial effects of this utility model are:

[0013] 1. By symmetrically setting a first sliding groove at the top of the clamp body and a second guide rail at the bottom, and setting a first guide rail matching the first sliding groove and a second sliding groove matching the second guide rail on the base, the base achieves a double sliding connection between the base and the clamp body through the cooperation of the first guide rail and the first sliding groove, and the second sliding groove and the second guide rail. This allows the base to be flexibly adjusted in position along the length of the clamp body, thereby improving the applicability of clamping and increasing the contact area between the dovetail clip and the clamped item, thus improving the reliability of clamping and fixing. By setting a first magnetic block at the beginning of the first guide rail and a second magnetic block at the end of the first sliding groove, when the base slides to the end of the first sliding groove, the first magnetic block and the second magnetic block attract each other and generate magnetic force, thereby preventing the dovetail clip from sliding during clamping and ensuring the stability after clamping.

[0014] 2. By providing a clamping arm within the first curved section fixedly connected to the base, the clamping arm passes through the first curved section and is connected to a nut on one side of the first curved section. This not only securely locks the clamping arm onto the first curved section but also directly limits the sliding range of the base, preventing the base from sliding out of the preset safe position or separating from the first curved section. The connecting grooves on both sides of the clamping body engage with the connecting strips on the base, ensuring a tight connection between the clamping body and the base in the retracted state, effectively preventing the clamping body and the base from loosening during clamping.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1 to 7 As shown, a novel dovetail clip includes a clip body 1 and bases 2 symmetrically arranged on both sides of the clip body 1. The top of the clip body 1 is symmetrically provided with a first sliding groove 11, and a first reinforcing rib 13 is provided on one side of the first sliding groove 11. The first reinforcing rib 13 is fixedly connected to the clip body 1 to reinforce the first sliding groove 11 and prevent the first sliding groove 11 from bending and deforming.

[0026] The base 2 is provided with a first guide rail 21 that matches the first slide groove 11. This sliding connection not only allows the base 2 to be flexibly adjusted along the length of the clamping body 1 to adapt to the clamping needs of items of different sizes, but also maintains a stable sliding trajectory during the clamping process to ensure the smoothness of the clamping action.

[0027] Furthermore, a second reinforcing rib 12 is fixedly connected to the inner bottom of the clamping body 1. The second reinforcing rib 12 is used to enhance the bending stiffness of the clamping body 1 and prevent the clamping body 1 from deforming or being damaged when clamping heavy items. A second guide rail 121 is fixedly connected to one side of the second reinforcing rib 12. A second sliding groove 22 matching the second guide rail 121 is provided on the base 2. The base 2 is slidably connected to both sides of the clamping body 1 through the first guide rail 21 and the second sliding groove 22, thereby realizing the double sliding connection of the base 2 on both sides of the clamping body 1.

[0028] Furthermore, the clamp 1 and the base 2 are connected by the first guide rail 21 and the first slide groove 11, and the second slide groove 22 and the second guide rail 121, which makes the base 2 more firmly fixed on both sides of the clamp 1 and can withstand greater external forces during sliding, thereby improving the overall load-bearing capacity of the dovetail clamp.

[0029] refer to Figure 4 , Figure 5 As shown, a first magnetic block 211 is provided at the first end of the first guide rail 21, and a second magnetic block 221 is provided at the end of the first slide groove 11. The first magnetic block 211 and the second magnetic block 221 are connected. When the base 2 slides to the end of the first slide groove 22, the first magnetic block 211 and the second magnetic block 221 attract each other and generate magnetic force. This design can not only effectively prevent the base 2 from continuing to slide, but also ensure that the base 2 remains stable after reaching the end of the first slide groove 22. Thus, the first magnetic block 211 and the second magnetic block 221 play a limiting role for the base 2.

[0030] refer to Figure 1 , Figure 2 As shown, the base 2 is fixedly connected to the two sides of the first curved part 3. The design of the first curved part 3 not only provides an installation position for the clamping arm 4, but also can adapt to the movement trajectory of the clamping arm 4. The clamping arm 4 is connected inside the first curved part 3. When the base 2 is slidable, the clamping arm 4 can extend and retract along the trajectory of the first curved part 3.

[0031] Furthermore, the clamping arm 4 passes through the first curved portion 3 and is connected to the nut 31 on one side of the first curved portion 3. This not only securely locks the clamping arm 4 onto the first curved portion 3, effectively preventing the clamping arm 4 from loosening or shifting within the first curved portion 3, but also, since the first curved portion 3 is fixed to the base 2, when the base 2 slides along the axial direction of the clamping arm 4, the nut 31 can directly limit the sliding range of the base 2. The nut 31 plays a sliding limiting role for the base 2, preventing the base 2 from sliding out of the preset safe position or separating from the first curved portion 3, thereby significantly improving the structural stability of the dovetail clamp.

[0032] In addition, the upper end of the clamping arm 4 is provided with a clamping part 41, and the outer side of the clamping part 41 is provided with anti-slip texture 411. The anti-slip texture 411 can enhance the friction between the finger and the clamping part 41, preventing slippage when pressing; and the anti-slip texture 411 can make the pressing action smoother and less strenuous, thereby improving the operating efficiency.

[0033] refer to Figure 2 , Figure 5 , Figure 6As shown, a second curved part 6 is fixedly connected to the bottom of the clamp 1. A spring 7 is provided inside the second curved part 6. The two ends of the spring 7 are fixed to the inner side of the clamp arm 4. As a pre-compressed helical spring, the spring 7 itself has a certain elastic force. When the base 2 needs to return to its original state, the extended spring 7 can assist the base 2 in overcoming the magnetic force under the action of the rebound force, making it easier for the base 2 to return to the initial position.

[0034] refer to Figure 4 As shown, the clamping body 1 has several connecting grooves 5 on both sides, and the base 2 has connecting strips 23 corresponding to the connecting grooves 5 on its inner side. The connecting strips 23 are fitted into the connecting grooves 5. The fitting design of the connecting strips 23 and the connecting grooves 5 allows the clamping body 1 and the base 2 to be tightly connected when in the retracted state, effectively preventing the clamping body 1 and the base 2 from loosening or shaking during the clamping process, thereby avoiding unstable clamping force or clamping failure of the dovetail clamp.

[0035] Furthermore, the cross-sectional shape of the connecting groove 5 is dovetail-shaped, and the cross-sectional shape of the connecting strip 23 matches the connecting groove 5. The dovetail-shaped cross-sectional design allows the connecting strip 23 to be firmly locked in the connecting groove 5 after being inserted. Moreover, due to the characteristic of the dovetail shape being wider at the top and narrower at the bottom, the connecting strip 23 will not easily come out of the connecting groove 5 when subjected to external force, thereby greatly enhancing the stability of the connection between the clamp 1 and the base 2 in the contracted state.

[0036] Working principle:

[0037] When small items need to be clamped, the dovetail clip is in a naturally retracted state. At this time, the base 2, with the cooperation of the connecting strip 23 and the connecting groove 5 on the clamp body 1, maintains a tight connection with the clamp body 1. This not only ensures a stable connection between the clamp body 1 and the base 2, but also provides sufficient support for the clamped items, preventing the items from swinging during the clamping process.

[0038] When clamping large or oddly shaped items, the base 2 slides outward along the first groove 11 on the clamping body 1 and the second groove 22 on the base 2. As the base 2 slides outward, it causes the first curved portions 3 fixedly connected to both sides and the clamping arms 4 passing through them to extend outward simultaneously. When the base 2 slides to the end of the first groove 22, the first magnet 211 and the second magnet 221 attract each other, generating a magnetic force, which fixes the base 2 at the end of the first groove 22. Therefore, the clamping surface length of the dovetail clip increases, resulting in a larger contact area between the dovetail clip and the clamped item, thus making the dovetail clip clamp the item more tightly.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
