Description

Technical Field

[0001] This invention relates to the technical field of torque-saving parallel grooved wire clamps, specifically a torque-saving parallel grooved wire clamp. Background Technology

[0002] Parallel groove clamps are used for connecting small- to medium-section aluminum stranded wires or steel-cored aluminum stranded wires, as well as steel stranded wires of overhead lightning protection wires, in positions where they are not subjected to tension. They are also used for jumper connections on non-straight towers. Parallel groove clamps are all non-load-bearing and mainly come in three types: bolt-type parallel groove clamps, H-type (or C-type) parallel groove clamps, and wedge-type parallel groove clamps. Among them, bolt-type parallel groove clamps are further divided into equal-diameter parallel groove clamps and unequal-diameter parallel groove clamps.

[0003] An existing torque-saving parallel groove wire clamp, when clamping and fixing wires of different diameters, cannot automatically adjust according to the diameter of the wire. This causes problems such as slippage or detachment when clamping and fixing wires of different sizes, reducing the adaptability and stability of the machine. Summary of the Invention

[0004] The purpose of this invention is to provide a torque-saving parallel groove clamp to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a torque-saving parallel grooved wire clamp, comprising a snap-fit ​​base, an adjustment device, a pressing device, and a fixing device disposed above the snap-fit ​​base; the adjustment device includes a wire clamp base, a movable wheel, a square block, a thin rod, an inclined plate, a hinge ring, a rubber clamp plate, and a spring piece; the bottom of the wire clamp base is fixedly connected to the top of the snap-fit ​​base, and a movable groove is formed on the surface of the wire clamp base, with the movable wheel slidably connected to the inner wall of the movable groove; one end of the thin rod is fixedly connected to the end of the fixing ring plate away from the movable wheel, and the surface of the thin rod is hinged to the inclined plate; the end of the inclined plate away from the thin rod is hinged to the hinge ring; the rubber clamp plate is fixedly connected to the end of the square block away from the movable wheel, and the rubber clamp plate is located above the wire clamp base; one end of the spring piece is fixedly connected to the inner wall of the movable groove, and the other end of the spring piece is fixedly connected to the surface of the movable wheel.

[0007] The wire clamp base is located above the snap-on base. There are four movable slots, which are arranged in a rectangular array on the surface of the wire clamp base. The number of rubber clamps is the same as the number of movable slots, and the four rubber clamps are fixed to the four square blocks one by one.

[0008] A thin rod passes through the inclined plate and extends to the outer end of the inclined plate. There are several inclined plates, and each pair of inclined plates forms a group corresponding to a hinge ring. The hinge ring is located at the center symmetrical position of the two inclined plates in each group. The surface of the moving wheel is adapted to the inner wall surface of the moving groove, and the axial direction of the moving wheel is perpendicular to the length direction of the moving groove.

[0009] The square block is vertically positioned above the moving wheel, with its axis parallel to the axis of the moving wheel; the fixing ring plate is located above the wire clamp base, extending in the same direction as the length of the wire clamp base, and its thickness is less than the height of the square block.

[0010] The extrusion device includes a threaded rod, a threaded cap, an extrusion upper plate, a locking block, a flexible rod, a wire clamp top cover, and a rubber pad. The bottom of the threaded rod is fixedly connected to the top of the wire clamp base. The threaded cap and the extrusion upper plate are both threadedly connected to the surface of the threaded rod, and the bottom of the threaded cap contacts the top of the extrusion upper plate. The top of the locking block is fixedly connected to the bottom of the extrusion upper plate. The surface of the locking base has a slot that matches the locking block, and the locking block can be inserted into the slot. One end of the flexible rod is fixedly connected to the bottom of the extrusion upper plate, and the other end is fixedly connected to the top of the wire clamp top cover. The rubber pad is fixedly connected to the side of the wire clamp top cover away from the flexible rod, and the rubber pad is located above the wire clamp base.

[0011] There are two threaded rods, which are symmetrically distributed on both sides of the snap-fit ​​base, and the axis of the threaded rods is perpendicular to the surface of the wire clamp base. There are four locking blocks, which are located at the four corners of the bottom of the extrusion plate, and the height of the locking blocks is adapted to the minimum distance from the extrusion plate to the snap-fit ​​base.

[0012] The flexible rods are vertically positioned close to each other on the extrusion plate and the wire clamp top cover. There are four flexible rods, which are arranged in a rectangular array between the extrusion plate and the wire clamp top cover. There are two wire clamp top covers, which are centrally symmetrical about the central axis of the threaded rod, and each wire clamp top cover corresponds to two flexible rods.

[0013] The length of the wire clamp top cover is less than the length of the extrusion plate, and neither end of the wire clamp top cover extends beyond the two ends of the extrusion plate.

[0014] The rubber clamp has an arc-shaped groove on the side of the surface away from the square block. The curvature of the arc-shaped groove matches the curvature of the outer circumference of the wire to be clamped, and the length of the arc-shaped groove is the same as the length of the rubber clamp. The inner wall surface of the arc-shaped groove has anti-slip texture, and the extension direction of the anti-slip texture is perpendicular to the length direction of the arc-shaped groove.

[0015] The fixing device includes a fixing frame, a short rod, a fixing ring, an anti-slip pad, and a long clamping plate. One end of the fixing frame is fixedly connected to the lower surface of the rubber clamp, and the other end extends towards the top cover of the wire clamp and is fixedly connected to the short rod. The axis of the short rod is parallel to the surface of the wire clamp base, and the fixing ring is rotatably sleeved on the surface of the short rod. The anti-slip pad is pasted and fixed to the side surface of the fixing ring near the top cover of the wire clamp. The long clamping plate is fixedly connected to the end of the fixing ring away from the short rod. The extension direction of the long clamping plate is consistent with the tangential direction of the fixing ring, and the thickness of the long clamping plate is the same as the thickness of the fixing ring.

[0016] The present invention has the following beneficial effects:

[0017] When the wire is placed above the rubber clamp, it squeezes the hinge ring, causing the hinge ring to push the fixed ring plates away from each other via the squeezing inclined plate. When the fixed ring plates are squeezed, they push the square block to move the moving wheel inside the moving groove, ensuring that the wire makes complete contact with the surface of the rubber clamp. This improves the machine's fixing effect and prevents problems such as the wire slipping out. At the same time, when the wire leaves the rubber clamp, the spring will push the moving wheel through pressure, thereby resetting the machine and improving its working efficiency and stability.

[0018] When the threaded cap is twisted, the extrusion plate moves downward on the surface of the threaded rod, clamping and fixing the wire. Simultaneously, as the extrusion plate moves downward, it pulls the locking block into the slot for further fixation, preventing positional shifts during machine operation. The downward movement of the extrusion plate also causes the wire clamp top cover and rubber pad to move downward via the flexible rod, clamping the wire. The flexible rod prevents excessive extrusion that could damage the wire and cause waste, while the rubber pad further protects the wire.

[0019] When the top cover of the wire clamp moves downward, the invention will compress the elongated clamping plate, causing the anti-slip pad to rotate on the surface of the short rod through the fixing ring, thus fixing the top cover of the wire clamp. This improves the stability of the machine and avoids problems such as falling off due to long-term operation. At the same time, the anti-slip pad and the elongated clamping plate will further fix the top cover of the wire clamp, preventing slippage and other problems.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1 - Figure 10 This application provides a torque-saving and grooved wire clamp, including a snap-fit ​​base 1. An adjustment device 2, a pressing device 3, and a fixing device 4 are disposed above the snap-fit ​​base 1. The adjustment device 2 includes a wire clamp base 20, a moving wheel 27, a square block 28, a thin rod 24, an inclined plate 25, a hinge ring 26, a rubber clamp 22, and a spring piece 29. The bottom of the wire clamp base 20 is fixedly connected to the top of the snap-fit ​​base 1. A moving groove 21 is formed on the surface of the wire clamp base 20, and the moving wheel 27 is slidably connected to the inner wall of the moving groove 21. One end of the thin rod 24 is fixedly connected to the end of the fixed ring plate 23 away from the moving wheel 27, and the surface of the thin rod 24 is hinged to the inclined plate 25; the end of the inclined plate 25 away from the thin rod 24 is hinged to the hinge ring 26; the rubber clamp 22 is fixedly connected to the end of the square block 28 away from the moving wheel 27, and the rubber clamp 22 is located above the wire clamp base 20; one end of the spring piece 29 is fixedly connected to the inner wall of the moving groove 21, and the other end of the spring piece 29 is fixedly connected to the surface of the moving wheel 27.

[0036] When the wire is placed above the clamp base 20, the wire presses against the hinge ring 26, causing the hinge ring 26 to rotate the inclined plate 25 hinged to it. The inclined plate 25 then pushes the thin rod 24 fixed to it, which in turn moves the fixed ring plate 23. The fixed ring plate 23 then pushes the square block 28 fixed to it, causing the square block 28 to slide along the inner wall of the moving groove 21 with the bottom moving wheel 27. Finally, the rubber clamp 22 fixed at the end of the square block 28 automatically conforms to the surface of wires of different diameters, achieving adaptive clamping of wires of different diameters and solving the diameter adaptation problem. At the same time, when the moving wheel 27 slides, it will press against the spring piece 29 (one end of the spring piece 29 is fixed to the inner wall of the moving groove 21 and the other end is fixed to the moving wheel 27). The spring piece 29 stores elastic potential energy to ensure subsequent reset, preventing the parts from not being able to return to their position after the wire falls out, which would affect the next use. Combined with the further clamping and fixing of the wire by the pressing device 3 and the reinforcement of the fixing device 4, the wire is effectively prevented from slipping and falling out, significantly improving the adaptability and stability of the clamp.

[0037] When the wire to be clamped is removed from above the rubber clamp 22, and the squeezing force of the wire on the hinge ring 26 disappears, the spring piece 29 in the adjusting device 2, one end of which is fixed to the inner wall of the moving groove 21 of the wire clamp base 20 and the other end of which is fixed to the surface of the moving wheel 27, will release the elastic potential energy stored in the moving wheel 27 due to its sliding, and push the moving wheel 27 to slide along the inner wall of the moving groove 21 to the initial position. The square block 28 fixed at the top of the moving wheel 27 moves synchronously with the moving wheel 27. On the one hand, it drives the rubber clamp 22, which is fixed away from the end of the moving wheel 27, to return from the unfolded state when it is in contact with the wire to the initial folded state. On the other hand, it drives the fixed ring plate 23, which is fixed on the surface, to move. The fixed ring plate 23 then pulls the thin rod 24, which is fixed away from the end of the moving wheel 27. The thin rod 24 pushes the inclined plate 25, which is hinged on the surface, to rotate around the hinge point. Finally, the hinge ring 26, which is hinged away from the end of the inclined plate 25, returns to the initial central symmetrical position where it is not squeezed. At this point, all components return to their initial state, and the reset work is completed.

[0038] In one possible implementation, the clamp base 20 is located above the snap-fit ​​base 1. Four movable slots 21 are formed, arranged in a rectangular array on the surface of the clamp base 20. The number of rubber clamps 22 matches the number of movable slots 21, with each of the four rubber clamps 22 corresponding to and fixed to one of the four square blocks 28. The rectangular array of the four movable slots 21 ensures a symmetrical arrangement of the corresponding movable wheels 27, square blocks 28, and rubber clamps 22, resulting in even force distribution on each clamp when holding the wire and preventing wire displacement due to excessive localized force. Each rubber clamp 22 corresponds to one of the square blocks 28, and each rubber clamp 22 can slide independently along the movable slot 21 with the square block 28, allowing for more flexible adaptation to wires of different diameters and a tighter fit.

[0039] As one possible implementation, the thin rod 24 passes through the inclined plate 25 and extends to the outer end of the inclined plate 25. The number of inclined plates 25 is several, and each pair of inclined plates 25 forms a group corresponding to a hinge ring 26. The hinge ring 26 is located at the center-symmetrical position of the two inclined plates 25 in each group. The surface of the moving wheel 27 is adapted to the inner wall surface of the moving groove 21, and the axial direction of the moving wheel 27 is perpendicular to the length direction of the moving groove 21.

[0040] The thin rod 24 passes through the inclined plate 25 and extends to its outer end, forming a through-type hinge structure. This prevents the inclined plate 25 and the thin rod 24 from separating when rotated under force, ensuring that the force when the wire squeezes the hinge ring 26 can be stably transmitted to the thin rod 24, reducing the risk of adjustment failure. Each pair of inclined plates 25 corresponds to one hinge ring 26, and the hinge ring 26 is located symmetrically at the center of the two sets of inclined plates 25. When the wire squeezes the hinge ring 26, the force can be evenly distributed to the two inclined plates 25 in the same group, so that the two inclined plates 25 rotate synchronously and push the thin rod 24 synchronously, avoiding component misalignment caused by uneven force transmission, and ensuring that the rubber clamp 22 symmetrically fits the wire. The surface of the moving wheel 27 is adapted to the inner wall of the moving groove 21, reducing the sliding gap and preventing the moving wheel 27 from shaking when sliding. Moreover, the axis of the moving wheel 27 is perpendicular to the length direction of the moving groove 21, limiting the moving wheel 27 to slide only along the length direction of the moving groove 21, ensuring that the square block 28 and the rubber clamp 22 move accurately along the preset trajectory, improving the adjustment accuracy and the synchronicity during reset.

[0041] For example, the square block 28 is vertically positioned above the moving wheel 27, and the axis of the square block 28 is parallel to the axis of the moving wheel 27; the fixing ring plate 23 is located above the wire clamp base 20, the extension direction of the fixing ring plate 23 is consistent with the length direction of the wire clamp base 20, and the thickness of the fixing ring plate 23 is less than the height of the square block 28.

[0042] The square block 28 is vertically positioned above the moving wheel 27 with their axes parallel. This allows the force to be transmitted vertically and without deviation to the rubber clamp 22 above the wheel as it slides along the moving groove 21, preventing the rubber clamp 22 from shifting due to the square block 28's tilt. Simultaneously, the square block 28 is limited to moving along the vertical trajectory corresponding to the moving wheel 27, ensuring the rubber clamp 22 precisely conforms to the wire and improving adjustment accuracy. The fixed ring plate 23 extends in the same direction as the wire clamp base 20, distributing the force transmitted by the thin rod 24 along the wire's length. This ensures the fixed ring plate 232 aligns the movement direction of the square block 28 and the rubber clamp 22 with the wire laying direction, preventing force deviation from causing wire misalignment and enhancing clamping stability.

[0043] In some embodiments, an arc-shaped groove is provided on the side surface of the rubber clamp 22 away from the square block 28. The curvature of the arc-shaped groove is adapted to the curvature of the outer circumference of the wire to be clamped, and the length of the arc-shaped groove is consistent with the length of the rubber clamp 22. The inner wall surface of the arc-shaped groove is provided with anti-slip texture, and the extension direction of the anti-slip texture is perpendicular to the length direction of the arc-shaped groove.

[0044] The arc-shaped groove on the side of the rubber clamp 22 away from the square block 28, because its curvature matches the outer circumference of the wire to be clamped and its length is consistent with the clamp, can greatly increase the contact area between the clamp and the wire, making the wire fit more tightly and avoiding the clamping looseness caused by local suspension; the anti-slip texture on the inner wall of the groove perpendicular to the length of the groove can enhance the friction between the clamp and the wire, hinder the wire's micro-movement along the axial or radial direction, and further prevent the wire from slipping. At the same time, the arc-shaped structure and the anti-slip texture can also reduce the squeezing damage to the wire surface during clamping, and improve the clamping stability and wire protection effect.

[0045] In some embodiments, the extrusion device 3 includes a threaded rod 30, a threaded cap 31, an extrusion upper plate 32, a locking block 33, a flexible rod 35, a wire clamp top cover 26, and a rubber pad 37. The bottom of the threaded rod 30 is fixedly connected to the top of the wire clamp base 20. The threaded cap 31 and the extrusion upper plate 32 are both threadedly connected to the surface of the threaded rod 30, and the bottom of the threaded cap 31 contacts the top of the extrusion upper plate 32. The top of the locking block 33 is fixedly connected to the bottom of the extrusion upper plate 32. The surface of the snap-fit ​​base 1 is provided with a slot 34 that is adapted to the locking block 33, and the locking block 33 can be inserted into the slot 34. One end of the flexible rod 35 is fixedly connected to the bottom of the extrusion upper plate 32, and the other end is fixedly connected to the top of the wire clamp top cover 36. The rubber pad 37 is fixedly connected to the side surface of the wire clamp top cover 36 away from the flexible rod 35, and the rubber pad 37 is located above the wire clamp base 20.

[0046] The threaded cap 31, which is threadedly connected to the threaded rod 30 in the twisting extrusion device 3, will push the extrusion plate 32 to move downward along the surface of the threaded rod 30 because the bottom of the threaded cap 31 contacts the top of the extrusion plate 32. When the extrusion plate 32 moves downward, the locking block 33 fixed at its bottom will be inserted into the matching slot 34 on the surface of the buckle base 1 to achieve positioning. At the same time, the flexible rod 35 fixed at the bottom of the extrusion plate 32 will drive the wire clamp top cover 36 to move downward, so that the rubber pad 37 fixed on the side of the wire clamp top cover 36 away from the flexible rod 35 is close to the wire above the wire clamp base 20, and finally the extrusion clamping of the wire is completed.

[0047] As one possible implementation, two threaded rods 30 are provided, symmetrically distributed on both sides of the snap-fit ​​base 1, and the axis of the threaded rods 30 is perpendicular to the surface of the wire clamp base 30; four snap-fit ​​blocks 33 are provided, located at the four corners of the bottom of the extrusion plate 32, and the height of the snap-fit ​​blocks 33 is adapted to the minimum distance from the extrusion plate 32 to the snap-fit ​​base 1.

[0048] Two threaded rods 30 are symmetrically distributed on both sides of the clamping base 1. When the threaded cap 31 is twisted to push the extrusion plate 32 downward, it can apply a balanced force to the extrusion plate 32 from both sides, preventing the extrusion plate 32 from tilting due to uneven force and ensuring that it always moves smoothly in the horizontal direction. Moreover, the axis of the threaded rod 30 is perpendicular to the surface of the wire clamp base 20, limiting the movement of the extrusion plate 32 only in the vertical direction, preventing it from shifting and causing misalignment of the wire clamping, and improving the accuracy of the clamping position. Four locking blocks 33 are located at the four corners of the bottom of the extrusion plate 32, forming a four-corner positioning structure. When the extrusion plate 32 moves downward, the four locking blocks 33 are simultaneously inserted into the locking slots 34 of the clamping base 1, limiting the extrusion plate 32 from four directions, greatly reducing the risk of shaking of the extrusion plate 32 during operation, and avoiding loosening of the clamping due to unstable positioning.

[0049] As one possible implementation, the flexible rods 35 are vertically positioned close to each other on the extrusion plate 32 and the wire clamp top cover 36; there are four flexible rods 35, which are arranged in a rectangular array between the extrusion plate 32 and the wire clamp top cover 36; there are two wire clamp top covers 36, which are centrally symmetrical about the central axis of the threaded rod 30, and each wire clamp top cover 36 corresponds to two flexible rods 35.

[0050] The vertical arrangement of the flexible rods 35 ensures that the downward pressure from the upper pressing plate 32 is transmitted vertically to the top cover 36 of the clamp, preventing the top cover from tilting. The four flexible rods are arranged in a rectangular array, with two corresponding to each top cover of the clamp, which ensures that each top cover is subjected to balanced force and prevents excessive local stress and deformation. The two top covers 36 of the clamp are symmetrically distributed about the central axis of the threaded rod 30, which can symmetrically clamp the wire. Combined with the balanced force transmission of the flexible rods, this not only improves the clamping stability but also avoids damage to the wire due to uneven clamping. It also fits the overall symmetrical structure of the clamp, ensuring smooth coordination of the components.

[0051] For example, the length of the wire clamp top cover 36 is less than the length of the extrusion plate 32, and neither end of the wire clamp top cover 36 extends beyond the end range of the extrusion plate 32.

[0052] In some embodiments, the fixing device 4 includes a fixing frame 40, a short rod 41, a fixing ring 42, an anti-slip pad 43, and an elongated clamping plate 44; one end of the fixing frame 40 is fixedly connected to the lower surface of the rubber clamp 22, and the other end extends towards the wire clamp top cover 37 and is fixedly connected to the short rod 41; the axis of the short rod 41 is parallel to the surface of the wire clamp base 20, and the fixing ring 42 is rotatably sleeved on the surface of the short rod 41; the anti-slip pad 43 is pasted and fixedly fixed to the side surface of the fixing ring 42 near the wire clamp top cover 37; the elongated clamping plate 44 is fixedly connected to the end of the fixing ring 42 away from the short rod 41, the extension direction of the elongated clamping plate 44 is consistent with the tangential direction of the fixing ring 42, and the thickness of the elongated clamping plate 44 is the same as the thickness of the fixing ring 42.

[0053] When the top cover 37 of the wire clamp in the compression device moves downward, it will first contact and compress the elongated clamping plate 44 at the end of the fixing ring 42 in the fixing device 4. Since the extension direction of the elongated clamping plate 44 is consistent with the tangential direction of the fixing ring 42, and the fixing ring 42 is rotatably sleeved on the surface of the short rod 41 (the short rod 41 is fixed to the lower surface of the rubber clamp 22 through the fixing bracket 40, and its axis is parallel to the surface of the wire clamp base 20), the elongated clamping plate 44 will drive the fixing ring 42 to rotate around the short rod 41 after being compressed, until the anti-slip pad 43 pasted on the fixing ring 42 is attached to the surface of the top cover 37 of the wire clamp. Finally, the friction of the anti-slip pad 43 is used to clamp and fix the top cover 37 of the wire clamp, thus completing the working process of the fixing device.

[0054] In use, when the wire is placed above the rubber clamp 22, the wire will squeeze the hinge ring 26. This causes the hinge ring 26 to push the fixed ring plate 23 away from each other via the pressure plate 25 and the thin rod 24. When the fixed ring plate 23 is squeezed, it pushes the square block 28, causing the moving wheel 27 to move inside the moving groove 21, ensuring complete contact between the wire and the surface of the rubber clamp 22. This improves the machine's fixing effect and prevents problems such as the wire slipping out. Simultaneously, when the wire leaves the rubber clamp 22, the spring 29 will push the moving wheel 27 under pressure, causing the machine to reset, improving its efficiency and stability. Twisting the threaded cap 31 will cause the pressure plate 32 to move downwards on the surface of the threaded rod 30, clamping and fixing the wire. Simultaneously, as the pressure plate 32 moves downwards, it will activate the locking block. 33 enters the slot 34 for further fixation, preventing positional shifts during machine operation. When the upper plate 32 moves downward, the flexible rod 35 drives the wire clamp top cover 36 and rubber pad 37 downward, clamping the wire. The flexible rod 35 prevents wire damage and waste due to excessive compression, while the rubber pad 37 further protects the wire. When the wire clamp top cover 36 moves downward, the long clamping plate 44 presses the anti-slip pad 43, which rotates on the surface of the short rod 41 via the fixing ring 42, fixing the wire clamp top cover 36 and improving machine stability. This prevents the wire clamp top cover from falling off during prolonged operation. The anti-slip pad 43 and the long clamping plate 44 further fix the wire clamp top cover 36, preventing slippage.
