Description

Technical Field

[0001] This utility model relates to the field of landscaping technology, specifically a torque clamp. Background Technology

[0002] Torque clamps are iron or aluminum metal accessories that can be fixed to conductors. Most of them need to withstand large tensile forces during operation, and some also need to ensure good electrical contact. They are used for corner, splicing and termination connections.

[0003] In the prior art, such as the torque clamp proposed in patent application number "CN202321162318.0", this utility model can adapt to the clamping and fixing of wires with different outer diameters, provide stable clamping force and is easy to install.

[0004] However, in the aforementioned patent application, when connecting the wire, it is necessary to place the wire in the groove of the torque clamp. However, after placing it in the groove, it is impossible to guarantee that the wire will not shift, and it is easy for the placement position to be incorrect, which affects the subsequent clamping and fixing of the wire by the torque clamp. Moreover, the clamping and fixing method only has a single pressing and fixing, and the clamping stability performance is insufficient. Utility Model Content

[0005] The purpose of this invention is to provide a torque clamp to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A torque clamp includes a main body one and a main body two. The upper surface of the main body one has several placement grooves, and the bottom surface of the main body two has several pressing grooves. An arc-shaped pressure plate is movably installed inside each of the placement grooves. Several adjustment mechanisms are provided between the front and rear end surfaces of the main body one and the interior of the placement grooves. Two bolts are inserted into the upper surface of the main body two. Two screw holes are provided on the upper surface of the main body one, and the screw holes and bolts cooperate with each other. An auxiliary mechanism is provided on the upper surface of the main body two.

[0008] The adjustment mechanism includes four connecting frames, two of which are fixedly connected to the front surface of the main body and the other two are fixedly connected to the back of the main body. A sliding rod is fixedly installed inside each of the four connecting frames.

[0009] Preferably, an L-shaped slider is sleeved on the outside of the slide rod, and one end of the L-shaped slider is fixedly connected to the arc-shaped pressure plate.

[0010] Preferably, a support spring is sleeved on the outside of the slide rod and at the position between the top of the connecting frame and the L-shaped slider, and two connecting plates are fixedly connected to the outer side wall of the arc-shaped pressure plate near both ends.

[0011] Preferably, an arc-shaped pressure plate two is movably disposed above the arc-shaped pressure plate one, and a screw is fixedly connected to the upper surface of the connecting plate two. The connecting plate one is sleeved on the outside of the screw, and one end of the connecting plate one is fixedly connected to the arc-shaped pressure plate two.

[0012] Preferably, nuts are fitted on the outside of the screw, between the second connecting plate and the first connecting plate, and above the first connecting plate.

[0013] Preferably, the auxiliary mechanism includes a housing, the upper ends of the two bolts are both disposed inside the housing, and gears are movably installed inside the housing near both ends, and the two gears are respectively fixedly connected to the upper ends of the two bolts.

[0014] Preferably, a second gear is rotatably connected to the inside of the outer casing and located between the two first gears via a shaft, and the second gear meshes with both first gears. A circular plate is fixedly connected to the upper surface of the second gear, and an annular plate is sleeved on the outside of the circular plate, and the annular plate is fixedly connected to the outer casing.

[0015] Preferably, the outer wall of the circular plate is rotatably connected to two movable plates via a shaft, and the upper surface of the annular plate has two fixed grooves that fit into the movable plates.

[0016] The movable plate has movable grooves on both outer side walls, and a locking block is inserted into each of the two movable grooves. A return spring is installed between one end of the locking block and the inner wall of the movable groove. The fixed groove has locking slots on both inner side walls, and the locking slots fit into the locking blocks.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model moves the arc-shaped pressure plate in the auxiliary mechanism upward, placing the wire to be connected in the placement groove and below the arc-shaped pressure plate. Under the action of the rebound force of the support spring, the arc-shaped pressure plate can move to the position where its inner wall is in contact with the outer wall of the wire, initially limiting and pressing the position of the placed wire, and initially aligning the wire to prevent the wire from shifting when the main body is pressed down, thus affecting the fixing effect. Furthermore, by adjusting the height of the arc-shaped pressure plate, the different distances between the arc-shaped pressure plate and the lower pressure groove at different heights are compensated, so that when the main body is pressed down, the arc-shaped pressure plate can be pressed down and fixed by squeezing the arc-shaped pressure plate, thereby further fixing the arc-shaped pressure plate and achieving double clamping and fixing of the wire, effectively improving the fixing and connection effect of the wire.

[0019] 2. In this utility model, after the bolt completes the connection between the main body one and the main body two by rotating the circular plate, the movable plate is rotated so that one end of the movable plate is inserted into the fixed groove. With the help of the locking block, the return spring and the locking groove, the position of the movable plate can be fixed, thereby fixing the position between the circular plate and the annular plate, fixing the position of the gear two, and then fixing the position of the two bolts, so as to avoid loosening and affecting the pressing and clamping effect on the wire.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] A torque clamp, such as Figures 1-5 As shown, the system includes a main body 1 and a main body 2. The upper surface of the main body 1 has several placement grooves 3, and the bottom surface of the main body 2 has several pressing grooves 24. An arc-shaped pressure plate 20 is movably installed inside each of the placement grooves 3. Several adjustment mechanisms are provided between the front and rear surfaces of the main body 1 and the interior of the placement grooves 3. Two bolts 13 are inserted into the upper surface of the main body 2. Two screw holes 23 are opened on the upper surface of the main body 1, and the screw holes 23 and bolts 13 cooperate with each other. An auxiliary mechanism is provided on the upper surface of the main body 2. The adjustment mechanism includes four connecting frames 4, two of which are fixedly connected to the front surface of the main body 1, and the other two are fixedly connected to the back surface of the main body 1. A sliding rod 6 is fixedly installed inside each of the four connecting frames 4.

[0030] An L-shaped slider 5 is fitted on the outside of the slide rod 6, and one end of the L-shaped slider 5 is fixedly connected to the arc-shaped pressure plate 20. A support spring is fitted on the outside of the slide rod 6 and between the top of the connecting frame 4 and the L-shaped slider 5. Two connecting plates 10 are fixedly connected to the outer side wall of the arc-shaped pressure plate 20 near both ends.

[0031] An arc-shaped pressure plate 21 is movably mounted above the arc-shaped pressure plate 20. A screw 8 is fixedly connected to the upper surface of the connecting plate 20. A connecting plate 7 is sleeved on the outside of the screw 8, and one end of the connecting plate 7 is fixedly connected to the arc-shaped pressure plate 21. Nuts 9 are sleeved on the outside of the screw 8, between the connecting plate 20 and the connecting plate 7, and above the connecting plate 7. By tightening the two nuts 9 along the screw 8 to the upper and lower surfaces of the connecting plate 7, the position of the connecting plate 7 can be fixed.

[0032] In use, the arc-shaped pressure plate 20 in the auxiliary mechanism is moved upward, and the two L-shaped sliders 5 follow and move upward along the slide rod 6 in the connecting frame 4. The support spring is compressed. Then, the wire to be connected is placed in one of the placement slots 3 and is located below the arc-shaped pressure plate 20. At this time, the arc-shaped pressure plate 20 is released. Under the action of the rebound force of the support spring, the arc-shaped pressure plate 20 can be moved down to the position where its inner wall is in contact with the outer wall of the wire. It can adapt to wires of different diameters and perform initial limiting and pressing on the position of the placed wire, so as to initially align the wire and fix its position, and prevent the wire from shifting when the main body 2 is pressed down later, which would affect the fixing effect.

[0033] After initially fixing the position of the wire, loosen the nut 9 located at the top to release the pressure on the connecting plate 7. Then, move the connecting plate 7 upward along the screw 8, causing the arc-shaped pressure plate 21 to move upward to a height that can coincide with the lower pressure groove 24. Then, tighten the two nuts 9 along the screw 8 to the upper and lower surfaces of the connecting plate 7 respectively, which can fix the position of the connecting plate 7, thereby fixing the position of the arc-shaped pressure plate 21. This compensates for the different gaps between the arc-shaped pressure plate 20 and the lower pressure groove 24 when the arc-shaped pressure plate 20 is at different heights. This allows the main body 2 to press down and fix the arc-shaped pressure plate 20 by squeezing it, thereby further fixing the arc-shaped pressure plate 20. This achieves double clamping and fixing of the wire, effectively improving the fixing and connection effect of the wire.

[0034] The auxiliary mechanism includes a housing 11, with the upper ends of two bolts 13 located inside the housing 11. Gears 12 are movably installed inside the housing 11 near both ends, and the two gears 12 are fixedly connected to the upper ends of the two bolts 13 respectively.

[0035] Inside the outer casing 11, located between the two gears 12, a gear 14 is rotatably connected via a shaft. The gear 14 meshes with both gears 12. A circular plate 15 is fixedly connected to the upper surface of the gear 14. An annular plate 22 is fitted around the circular plate 15 and is fixedly connected to the outer casing 11. Rotating the circular plate 15 causes the gear 14 to rotate, thereby causing the two gears 12 to rotate simultaneously, and causing the two bolts 13 to rotate simultaneously.

[0036] Two movable plates 16 are rotatably connected to the outer wall of the circular plate 15 via a shaft. Two fixed grooves 17 are opened on the upper surface of the annular plate 22, and the fixed grooves 17 fit with the movable plates 16. Movable grooves are opened on both outer walls of the movable plates 16, and locking blocks 18 are inserted into both movable grooves. A return spring is installed between one end of the locking block 18 and the inner wall of the movable groove. Locking slots 19 are opened on both inner walls of the fixed grooves 17, and the locking slots 19 fit with the locking blocks 18. Under the action of the return spring, one end of the locking block 18 is locked into the locking slot 19, which can fix the position of the movable plate 16, thereby fixing the position between the circular plate 15 and the annular plate 22.

[0037] Specifically, after placing each wire in its respective slot 3, the circular plate 15 is rotated, which drives the gear 14 to rotate, thereby driving the two gears 12 to rotate simultaneously, and the two bolts 13 to rotate simultaneously. The bottom ends of the two bolts 13 rotate along the inside of the screw hole 23 and gradually extend into the screw hole 23, which can drive the main body 2 to move down and get closer to the main body 1, so that each pressing slot 24 is tightly attached to each arc-shaped pressure plate 21, pressing down and fixing the arc-shaped pressure plate 21, thereby pressing down each arc-shaped pressure plate 20, and completing the further clamping and fixing of each wire.

[0038] After rotating the circular plate 15 to connect the main body 1 and the main body 2 with the bolt 13, rotate the movable plate 16 so that one end of the movable plate 16 is inserted into the fixed groove 17. During this process, the two locking blocks 18 move with the movable plate 16. The inclined part of the locking block 18 moves along the inner wall of the fixed groove 17, gradually causing the locking block 18 to retract into the movable groove. The return spring is compressed. When the movable plate 16 is completely inserted into the fixed groove 17, one end of the locking block 18 is flush with the groove 19. Under the action of the return spring, one end of the locking block 18 is inserted into the groove 19, which can fix the position of the movable plate 16, thereby fixing the position between the circular plate 15 and the annular plate 22, fixing the position of the gear 2 14, and then fixing the position of the two bolts 13, so as to prevent loosening and affect the pressing and clamping effect on the wire.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
