Description
Technical Field
[0001] The present invention relates to the field of joystick devices, and more particularly, to a bendable short - circuit grounding wire operating device. Background Art
[0002] The short - circuit grounding wire is a very important safety tool in electric power safety operations. Among them, for the existing screw - type short - circuit grounding wire, its insulating operating rod, fastening clip, and wire end clip of the grounding wire are sequentially connected and arranged on the same axis, and are connected by a screw fixed on the insulating rod. When operating personnel install or remove the grounding wire, by rotating the insulating operating rod, the fastening clip generates a linear displacement, making the wire end clip clamp or loosen on the grounded conductor, and at the same time, a short - circuit grounding wire is fixed on the wire end clip.
[0003] However, for the existing short - circuit grounding wire, its wire end clip is installed on the screw fixed to the insulating operating rod. Since the insulating operating rod, fastening clip, and wire end clip in the short - circuit grounding wire can only move linearly along the axis, the insulating operating rod cannot be bent in the direction around the axis. When the operating personnel are on a special operation table, it is difficult to meet the operations at different angles. In addition, a set of portable short - circuit grounding wires requires multiple insulating operating rods to be used in a matching manner, which increases the operation load during the hoisting and lowering during installation and removal at high altitude. Summary of the Invention
[0004] The present invention aims to overcome the defect that the insulating operating rod of the short - circuit grounding wire in the above - mentioned prior art cannot be bent according to requirements, and provides a bendable short - circuit grounding wire operating device.
[0005] To solve the above - mentioned technical problems, the technical solution of the present invention is as follows:
[0006] A bendable short - circuit grounding wire operating device includes an operating rod, a fastening screw, a grounding wire clip, and a direction - changing device. Among them, the direction - changing device includes a sleeve and a universal joint. One end of the sleeve is fixedly connected to one end of the operating rod; the other end of the sleeve is open; axial guide grooves are provided on both side surfaces of the sleeve; protrusion structures are provided on both sides of the universal joint, and the universal joint is slidably connected to the guide grooves through the protrusion structures. When the universal joint slides to the end of the guide groove close to the opening of the sleeve, the direction - changing end of the universal joint extends out of the sleeve; the direction - changing end of the universal joint is connected to one end of the fastening screw; the grounding wire clip includes a clip body and a fastening clip. A short - circuit wire installation hole is provided on one outer side of the clip body, and a through - hole screw hole is provided on the lower surface of the clip body; one side of the fastening clip is slidably connected along the inner side surface of the clip body, and a hole - shaped card slot is provided on the lower side surface of the fastening clip; a round - head card is provided at the other end of the fastening screw, and the fastening screw is threadedly connected to the screw hole provided on the lower surface of the clip body, and the round - head card is clamped with the hole - shaped card slot.
[0007] In this technical solution, a steering device for realizing axis-around variable direction and rotation is added. Under normal conditions, the protruding structures arranged on both sides of the universal joint slide to one end of the guide groove far from the opening of the sleeve. At this time, the whole universal joint is arranged inside the sleeve, so that the operating rod maintains a stable axial connection relationship. When the direction of the operating rod needs to be adjusted, by pulling the operating rod, the protruding structures arranged on both sides of the universal joint slide to one end of the guide groove close to the opening of the sleeve. At this time, the steering end of the universal joint extends out of the sleeve, and the fastening screw connected to the steering end can change the included angle between it and the operating rod according to the operation requirements, so as to meet the operations at different angles. During use, first install the fastening screw and the grounding wire clamp. The main body of the fastening screw passes through the screw hole opened on the lower surface of the clamp body in the grounding wire clamp and is threadedly connected thereto. The round head clip arranged at the other end of the fastening screw is clamped with the hole-shaped card slot arranged on the lower side of the fastening clip in the grounding wire clamp. Then connect the steering end of the universal joint to one end of the fastening screw, and the installation of the operating rod is completed. When preparing to install the grounding wire, first adjust the position of the fastening clip in the grounding wire clamp relative to the clamp body by rotating the operating rod to drive the rotation of the fastening screw according to the size of the conductor to be grounded. The operator can then clamp the grounding wire clamp onto the target conductor according to the operation requirements. When the grounding wire clamp is clamped onto the conductor, the operator can pull the operating rod to move the sleeve in the steering device connected thereto downward. At this time, the protruding structures arranged on both sides of the universal joint slide to one end of the guide groove close to the opening of the sleeve, and the steering end of the universal joint extends out of the sleeve. The operating rod can be bent arbitrarily under the steering action of the universal joint, and the operator can rotate the operating rod at any angle according to the actual use situation, so that the fastening clip in the grounding wire clamp further clamps or loosens the conductor under the rotation action of the fastening screw.
[0008] Preferably, pins are arranged through both sides of the universal joint. The two ends of the pins serve as protruding structures and are slidably connected to the guide groove. First compression springs are sleeved on the two ends of the pins, and the universal joint is fixed inside the sleeve through the first compression springs. The two ends of the pins extend out of the guide groove, and the two ends of the pins are arranged on the outer side surface of the sleeve through round washers and round head nuts. Among them, the compression spring is used to overcome the self-gravity of the universal joint and other components connected to the universal joint, so as to prevent the universal joint from sliding along the guide groove under the action of the self-gravity of the operating rod or the universal joint during the use of the operating rod.
[0009] Preferably, a sleeve is arranged at one end of the fastening screw. An L-shaped slot is opened on the sleeve. One end of the L-shaped slot is arranged at the end of the sleeve, and the long side of the L-shaped slot is perpendicular to the end of the sleeve. A card member matching the L-shaped slot is arranged on the outer circumference of the end of the steering end of the universal joint. The first connecting rod is slidably connected to the sleeve along the L-shaped slot through the card member arranged at its end, realizing the detachable connection between the steering device and the fastening screw.
[0010] In this preferred solution, the detachable connection between the sleeve with a slot provided at one end of the fastening screw and the steering end of the universal joint enables the detachable installation of the operating rod and the grounding wire clamp. The operator can use one operating rod to install or remove other similar short-circuit grounding wires, reducing the investment in operating rods. During use, when the operating rod needs to be removed, the operating rod is pushed along the axial direction while being rotated, so that the clamping member provided on the outer periphery of the end of the steering end of the universal joint slides along the L-shaped slot and exits the sleeve, thereby realizing the separation of the operating rod and the grounding wire clamp. When it is necessary to install the operating rod to remove the short-circuit grounding wire, by pushing the operating rod, the clamping member provided at the end of the steering end of the universal joint is slid into the sleeve along the L-shaped slot, and then the operating rod is rotated so that the clamping member at the end of the steering end of the universal joint is clamped at the corner of the L-shaped slot, that is, the installation of the operating rod is completed. At this time, the operating rod is rotated again so that the fastening clamp in the grounding wire clamp is further loosened from the wire under the rotation of the fastening screw, that is, the removal operation of the short-circuit grounding wire is completed.
[0011] Preferably, a second compression spring is provided between the end of the steering end of the universal joint and the sleeve, which is used to hold the end of the steering end of the universal joint firmly to prevent the clamping member provided on the universal joint steering end from loosening from the L-shaped slot.
[0012] Preferably, one end of the operating rod is provided with a connecting rod, the outer side surface of one end of the sleeve is provided with a fixing groove, the top end of the connecting rod is arranged in the fixing groove, and the connecting rod and the fixing groove are connected and fixed by a U-shaped spring pin. In this preferred solution, the operating rod can be detachably connected to the steering device through the U-shaped spring pin, which is convenient for replacing the operating rod that has rusted or worn out.
[0013] Preferably, an insulating sheath is sleeved on the outer surface of the other end of the operating rod.
[0014] Preferably, the short - circuit grounding wire operating device further includes a directional card slot. The directional card slot includes a card slot body and a card slot base. Among them, the card slot body matches the shape of the sleeve; the card slot base is a U - shaped base, and the card slot base is clamped and fixed to the lower part of the clamp body. A fixing piece is arranged outward on one side of the card slot base. The card slot body is connected to the fixing piece by a pin and a torsion spring. In this preferred solution, the added directional card slot is used to fix the opening direction of the grounding wire clamp by clamping the sleeve in the direction - changing device according to the operation requirements when installing the grounding wire on the operating rod. During use, when preparing to install the grounding wire, after adjusting the position of the fastening clip in the grounding wire clamp relative to the clamp body, press down the directional card slot to clamp the sleeve of the direction - changing device, and the opening direction of the grounding wire clamp can be fixed. The operator can more effectively clamp the grounding wire clamp onto the target conductor according to the operation requirements. When it is necessary to remove the operating rod, the operator pulls the operating rod to move the sleeve in the direction - changing device connected to it downward. At this time, the protruding structures arranged on both sides of the universal joint slide to one end of the guide groove close to the opening of the sleeve, and the direction - changing end of the universal joint extends out of the sleeve. At this time, the sleeve slides relative to the directional card slot, so that the sleeve is disengaged from the clamping action of the directional card slot.
[0015] Preferably, a limiting spring piece is arranged inward at the opening position of the card slot body, and this limiting spring piece is used to enhance the clamping effect of the directional card slot.
[0016] Preferably, a handle is arranged outward at the opening position of the card slot body, which is convenient for the operator to manually adjust the clamping or loosening of the directional card slot and the sleeve.
[0017] Preferably, the sleeve in the direction - changing device is a square sleeve, and the card slot body in the directional card slot is a square card slot that matches the shape of the sleeve.
[0018] Compared with the prior art, the beneficial effects of the technical solution of the present invention are as follows: Through the direction - changing device arranged between the fastening screw rod and the operating rod, the axial connection between the operating rod and the fastening screw rod and the transformable operation of bending around the axis are realized, meeting the operation requirements of the operator at different angles; Through the detachable connection between the fastening screw rod and the direction - changing device, the disassembly and assembly of the same type of short - circuit grounding wire are realized using one operating rod, reducing the investment in operating rods, and thus reducing the operation load during high - altitude disassembly, installation, hoisting and dropping; Through the clamping effect of the directional card slot on the direction - changing device, the opening direction of the grounding wire clamp can be effectively fixed, facilitating the operator to clamp the clamp onto the target conductor.

[0051] Embodiment 3
[0052] As Figure 6 shown, it is a schematic structural diagram of the bendable short-circuit grounding wire operating device of this embodiment.
[0053] A bendable short-circuit grounding wire operating device proposed in this embodiment adds a directional card slot 5 on the basis of the bendable short-circuit grounding wire operating device proposed in Embodiment 2.
[0054] The directional card slot 5 in this embodiment includes a card slot body 51 that matches the shape of the sleeve 21 in the direction-changing device 2, and a card slot base 52 for fixing the card slot body 51. Among them, the card slot body 51 matches the shape of the sleeve 21 in the direction-changing device 2; the card slot base 52 is a U-shaped base, and the card slot base 52 is clamped and fixed to the lower part of the clamp body 4. A fixing member 53 is arranged outward on one side of the card slot base 52, and the card slot body 51 is connected to the fixing member 53 by a pin and a torsion spring.
[0055] As Figure 7 shown, it is a schematic structural diagram of the directional card slot 5 of the bendable short-circuit grounding wire operating device in this embodiment.
[0056] In this embodiment, a limiting spring piece 54 is arranged inward at the opening position of the card slot body 51, and the limiting spring piece 54 is used to enhance the clamping effect of the directional card slot 5 on the sleeve 21.
[0057] In this embodiment, a handle 55 is arranged outward at the opening position of the card slot body, which is convenient for the operator to manually adjust the clamping or loosening of the directional card slot and the sleeve.
[0058] In this embodiment, the sleeve 21 in the direction-changing device 2 is a square sleeve, and the card slot body 51 in the directional card slot 5 is a square card slot that matches the shape of the sleeve 21.
[0059] As Figure 8 、 9 shown, it is a usage state diagram of the bendable short-circuit grounding wire operating device in this embodiment. In the specific implementation process, when preparing to install the grounding wire, as Figure 8 shown in the usage state (1) in Figure 8 , after the operator adjusts the position of the fastening clip 42 in the grounding wire clamp 4 relative to the clamp body 41, presses down the card slot body 51 in the directional card slot 5 to clamp the sleeve 21 of the direction-changing device 2, the opening direction of the grounding wire clamp can be fixed, and the operator can more effectively clamp the grounding wire clamp onto the target conductor according to the operation requirements. When it is necessary to remove the operating rod 1, as Figure 8 shown in the usage state (2) in
[0060] , the operator pulls the operating rod 1 to move the sleeve 21 in the direction-changing device 2 connected to it to the right. The protruding structures 223 arranged on both sides of the universal joint 22 slide to one end of the guide groove 211 close to the opening of the sleeve 21, and the direction-changing end 221 of the universal joint 22 extends out of the sleeve 21. At the same time, the sleeve 21 slides relative to the directional card slot 5, so that the sleeve 21 is disengaged from the clamping effect of the directional card slot 5, and the directional card slot 5 bounces up. In this state, as shown in the usage state (3) in
[0060] , because the direction-changing end 221 of the universal joint 22 extends out of the sleeve 21, the operating rod 1 can be bent arbitrarily under the direction-changing action of the universal joint 22. When it is necessary to remove the operating rod 1, asFigure 9 As shown in state (1), it is the state where the grounding wire clamp is clamped onto the target conductor. At this time, the operator pulls the operating rod 1 in the axial direction, causing the sleeve 21 in the phase-changing device 2 connected to it to move to the right. The protruding structures 223 provided on both sides of the universal joint 22 slide to one end of the guide groove 211 close to the opening of the sleeve 21, and the universal joint 22 extends out of the opening end of the sleeve 21. At the same time, the sleeve 21 slides relative to the directional card slot 5, causing the sleeve 21 to be disengaged from the clamping action of the directional card slot 5, and the directional card slot 5 pops up, as Figure 9 shown in state (2). Then, the operating rod 1 is pushed to the left, and the universal joint 22 is reinserted into the sleeve 21, making the main body of the combination of the operating rod 1 and the phase-changing device 2 in a rigid connection state, as Figure 9 shown in state (3). Then, the operating rod 1 is rotated, and the clamping member 223 provided at the end of the universal joint 22 slides along the L-shaped slot provided in the fastening screw 3 and exits the sleeve 32, thereby realizing the separation of the operating rod 1 from the grounding wire clamp 4, as Figure 9 shown in state (4), that is, the removal of the operating rod 1 is completed.
[0061] In this embodiment, the additionally provided directional card slot 5 is used to fix the opening direction of the grounding wire clamp 4 by clamping the sleeve 21 in the phase-changing device 2 according to the operation requirements when the operating rod is installing the grounding wire.
