The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

It should be noted that all directional indicators (such as upper, lower, left, right, front, back, inner, outer, top, bottom … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components in a specific posture (as shown in the figure), and if the specific posture is changed, the directional indicator is changed accordingly.

It will also be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Referring to fig. 1 and fig. 2, a wire clamp 1 according to an embodiment of the present invention includes a first clamping member 10, a second clamping member 20, and a sliding rail 30. The first clamping member 10 and the second clamping member 20 are both mounted on the slide rail 30 and can slide on the slide rail 30 along a slide axis. When the first clamping member 10 and the second clamping member 20 move towards each other, the first clamping member 10 and the second clamping member 20 gradually approach to clamp the wire, and when the first clamping member 10 and the second clamping member 20 move away from each other, the first clamping member 10 and the second clamping member 20 gradually move away from each other to release the clamped wire.

In the present application, the slide rail 30 is a single linear guide rail and has a long bar shape, the sliding axis is the length direction of the slide rail 30 (i.e. the longitudinal direction of the slide rail 30), and the first clamping member 10 and the second clamping member 20 can slide along the length direction of the slide rail 30.

At least one of the first clamping member 10 and the second clamping member 20 is provided with a wire slot 201 for the wire to pass through, so as to form a limiting positioning effect on the wire. The raceway 201 includes two spaced opposed side walls and a bottom wall therebetween that is recessed to form a curved surface 202 for better conforming to the outer surface of the cylindrical wire.

The specific number of the wire slots 201 is not limited at all, and in the illustrated embodiment, the wire slots 201 are provided in plurality, so that the wire clamp 1 can clamp a plurality of wires at the same time, which is beneficial to improving the production efficiency.

In the illustrated embodiment, the wire slots 201 are disposed on the second clamping member 20, and the plurality of wire slots 201 are sequentially arranged at intervals in a direction perpendicular to the length direction of the sliding rail 30, i.e., in the transverse direction, so as to form a comb-shaped structure.

The wire clamp 1 further comprises a base 40 and a supporting column 50 installed on the base 40, and the sliding rail 30 is fixedly installed on one side of the supporting column 50. The base 40 is used for fixing to an external element such as a machine table, and the supporting column 50 is used for supporting the sliding rail 30 thereon.

In the illustrated embodiment, the second clamping member 20 is closer to the base 40 than the first clamping member 10 in the longitudinal direction of the slide rail 30, and there is a certain distance between the bottom of the slide rail 30 and the base 40, so that the second clamping member 20 can be partially separated from the slide rail 30 during the back-and-forth movement of the first clamping member 10 and the second clamping member 20, thereby leaving more movement space for the second clamping member 20.

Referring to fig. 3 and 4, the wire clamp 1 further includes a link mechanism 60, the link mechanism 60 includes a rotating member 61, a first connecting member 62 and a second connecting member 63, and both the first connecting member 62 and the second connecting member 63 are movably connected to the rotating member 61. The first connecting member 62 is connected to the first holding member 10 and can move together with the first holding member 10, and the second connecting member 63 is connected to the second holding member 20 and can move together with the second holding member 20. The rotating member 61 is positioned to rotate relative to the slide rail 30 but not move along the sliding axis, so that when one of the first clamping member 10 and the second clamping member 20 slides on the slide rail 30 in one direction, the other of the first clamping member 10 and the second clamping member 20 can be driven to slide on the slide rail 30 in the other opposite direction by the link mechanism 60, that is, the first clamping member 10 and the second clamping member 20 can move towards or away from each other by the link mechanism 60, so as to move the first clamping member 10 and the second clamping member 20 towards or away from each other. When the first and second clamping members 10 and 20 are close to each other, they can be engaged to clamp the wire, and when the first and second clamping members 10 and 20 are far away from each other, they can be disengaged from the clamped wire. Because first holder 10 and second holder 20 are realized through link mechanism 60 towards each other or back-to-back movement, link mechanism 60 compares in the cooperation of gear and rack, and is lower relatively to the requirement of precision, consequently is favorable to reducing the processing degree of difficulty and processing cost, also can reduce the dead risk of card simultaneously, promotes product reliability.

In the illustrated embodiment, the rotating member 61 is rotatably mounted on a side of the supporting column 50 away from the slide rail 30 by the first fastening member 64, and a length direction of the rotating member 61 is not consistent with a length direction of the slide rail 30, i.e. the rotating member and the slide rail are at an angle in the length direction. Specifically, the middle part of the rotating member 61 is provided with a connecting hole 611 in a penetrating manner, one end of the first fastening member 64 is connected to the supporting column 50 after penetrating through the connecting hole 611, and the rotating member 61 is rotatably mounted on the supporting column 50, so that the rotating member 61 can only rotate around the first fastening member 64 relative to the sliding rail 30, and cannot move along the sliding axis.

Both ends of the rotation member 61 are connected to the first connection member 62 and the second connection member 63 through a second fastening member 65, respectively, and both ends of the rotation member 61 are provided with mounting grooves 612, respectively. The installation groove 612 is waist-shaped, the length direction of the installation groove 612 is consistent with the length direction of the rotating member 61, one end of the second fastening member 65 is connected with the first connecting member 62 or the second connecting member 63, and the other end is movably inserted into the corresponding installation groove 612. During the movement of the second fastening member 65 following the first connecting member 62 or the second connecting member 63, one end of the second fastening member 65 in the mounting groove 612 slides along the length direction of the mounting groove 612, so that the rotating member 61 is driven to rotate around the first fastening member 64. And the operator can adjust the distance between the first clamping member 10 and the second clamping member 20 by adjusting the position of the second fastening member 65 in the mounting groove 612.

The middle part of the rotating part 61 is rotatably connected with the supporting column 50, and the two ends are respectively movably connected with the first connecting part 62 and the second connecting part 63. When the first clamping member 10 moves towards the base 40, the first connecting member 62 is driven to move towards the base 40, the first connecting member 62 drives the rotating member 61 to rotate around the first fastening member 64 in the moving process, and the end of the rotating member 61 connected with the first connecting member 62 moves towards the base 40, the end of the rotating member 61 far away from the first connecting member 62, that is, the end connected with the second connecting member 63 moves towards the direction far away from the base 40, and drives the second connecting member 63 to move towards the direction far away from the base 40, the second connecting member 63 drives the second clamping member 20 to move towards the direction far away from the base 40, and finally the first clamping member 10 and the second clamping member 20 move towards each other to clamp the wire. On the contrary, when the first clamping member 10 moves in the direction away from the base 40, the end of the rotating member 61 connected to the first connecting member 62 moves in the direction away from the base 40 under the action of the first connecting member 62, and the end of the rotating member 61 connected to the second connecting member 63 drives the second clamping member 20 to move in the direction toward the base 40 through the second connecting member 63, so that the first clamping member 10 and the second clamping member 20 move away from each other to release the clamped wire.

The first fastening member 64 and the second fastening member 65 are not limited in particular, and may be, for example, bolts, shafts, or the like.

Referring to fig. 5 and 6, the first clamping member 10 includes a first clamping portion 11 and a first sliding block 12, and the first sliding block 12 is slidably mounted on the sliding rail 30 and can slide along the longitudinal direction of the sliding rail 30. The first clamping portion 11 is connected to the first slider 12, and the first connecting member 62 is connected to the first clamping portion 11. When the first sliding block 12 slides on the sliding rail 30, the first clamping portion 11 and the first connecting member 62 can be driven to move together.

The second clamping member 20 includes a second clamping portion 21 and a second slider 22, and a wire slot 201 is provided on the second clamping portion 21 for cooperating with the first clamping portion 11 to clamp or release a wire. The second sliding block 22 is slidably mounted on the sliding rail 30 and can slide along the longitudinal direction of the sliding rail 30. The second clamping portion 21 is connected to the second slider 22, and the second connecting member 63 is connected to the second clamping portion 21. When the second sliding block 22 slides on the sliding rail 30, the second clamping portion 21 and the second connecting member 63 are driven to move together.

Referring also to fig. 1, in some embodiments, the wire clamp 1 further includes an actuator 70, and the actuator 70 is connected to the first clamping portion 11 or the second clamping portion 21 to drive the first clamping member 10 or the second clamping member 20 to slide on the slide rail 30.

The specific type of the driver 70 is not limited, and may be, for example, a motor or an air cylinder, as long as the driver can drive the first clamping member 10 or the second clamping member 20 to slide on the slide rail 30. In the illustrated embodiment, the actuator 70 is a cylinder, and a piston rod of the cylinder is connected to the first clamping portion 11, and when the piston rod of the cylinder performs a piston movement, a force is applied to the first clamping portion 11, so that the first clamping member 10 slides on the slide rail 30, and the second clamping member 20 moves towards or away from the first clamping member 10 under the action of the link mechanism 60.

In the illustrated embodiment, the first slider 12 and the second slider 22 are both provided with a sliding slot 121, the sliding slot 121 penetrates through the first slider 12 and the second slider 22 along the length direction of the sliding rail 30, and the sliding rail 30 movably penetrates through the sliding slots 121 on the first slider 12 and the second slider 22, so that the sliding rail 30 is in sliding fit with the first slider 12 and the second slider 22.

The size of the first sliding block 12 and the second sliding block 22 in the transverse direction is larger than that of the sliding rail 30 in the transverse direction, and the sliding groove 121 is formed in the middle of the first sliding block 12 and the second sliding block 22, so that the stability of the first sliding block 12 and the second sliding block 22 in the movement process can be improved.

In the illustrated embodiment, the first slider 12 and the second slider 22 are located on opposite sides of the rotating member 61 in the longitudinal direction of the slide rail 30, i.e., the sliding axis direction. The first link 62 and the second link 63 are located at opposite sides of the slide rail 30, respectively, in the lateral direction of the slide rail 30.

Two opposite sides of the first connecting element 62 and the second connecting element 63 (i.e. the side of the first connecting element 62 close to the first sliding block 12 and the side of the second connecting element 63 close to the second sliding block 22) are respectively provided with a notch 621. Because the size of the first slider 12 and the second slider 22 in the transverse direction is larger than that of the slide rail 30, the notch 621 of the first connecting member 62 can avoid the part of the first slider 12 located outside the slide rail 30, and the notch 621 of the second connecting member 63 can avoid the part of the second slider 22 located outside the slide rail 30, so that the compactness of the overall structure of the wire clamp 1 is improved.

According to the wire clamp, the first clamping piece and the second clamping piece are connected through the connecting rod mechanism, so that when one of the first clamping piece and the second clamping piece slides on the sliding rail along one direction, the other of the first clamping piece and the second clamping piece can be driven to slide on the sliding rail along the other opposite direction through the connecting rod mechanism, and finally the first clamping pieces are close to or far away from each other to clamp or loosen a wire. Compared with the matching of a gear and a rack, the connecting rod mechanism has relatively low requirement on precision, so that the processing difficulty and the processing cost are reduced, the risk of blocking can be reduced, and the reliability of a product is improved.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
