A fixed seat 200 is arranged between the upper wire clamp and the insulating rod 800, and the positioning shaft 400 upwards passes through the fixed seat 200; the lower part of the upper wire clamp is hinged with the fixed seat 200, and the fixed seat 200 is provided with a fixed structure for relatively fixing the upper wire clamp and the fixed seat 200. Therefore, according to actual needs, the swinging angle of the upper clamping jaw 100 can be adjusted by swinging the upper wire clamp, and the swinging upper wire clamp is fixed by utilizing the fixing structure.
In this embodiment, the outer end of the upper clamping jaw 100 extends downwards to form a stopper 101, and the stopper 101 extends towards the lower clamping jaw 102, so that when the upper clamping jaw 100 and the lower clamping jaw 102 clamp a wire or a copper bar, the stopper 101 can play a role in stopping the wire or the copper bar from being separated.
In the grounding wire device with the swinging angle, when in operation, after the upper clamping jaw 100 of the upper wire clamp is arranged above a wire or copper bar, only the insulating rod 800 needs to be slightly pulled downwards, the linkage structure drives the lower clamping jaw 102 to move upwards, the upper clamping jaw 100 and the lower clamping jaw 102 clamp the wire or copper bar, then the insulating rod 800 is rotated clockwise (the rotation is less than 1 circle), the device is immediately locked, the lower clamping jaw 102 is driven to continuously apply clamping force towards the direction of the wire or copper bar, so that the clamping is stable, the wire or copper bar is prevented from being separated from the grounding wire device, the operation is simple, time and labor are saved, when the grounding wire device needs to be detached from the wire or copper bar, only the insulating rod 800 needs to be rotated anticlockwise (the rotation is less than 1 circle) to reset to the initial state, the device is immediately unlocked, then the insulating rod 800 is pushed upwards, and the lower clamping jaw 102 is driven to move downwards through the linkage structure, and the upper jaw 100 is removed from the wire or copper bar.
Because the lower part of the upper wire clamp is hinged with the fixed seat 200, the angle adjustment of the upper clamping jaw 100 can be realized by swinging the upper wire clamp, and the upper wire clamp and the fixed seat 200 are relatively fixed by using a fixed structure.
The fixing structure can be diversified, in this embodiment, the relative fixation between the wire clip and the fixing seat 200 is realized through the rotation of the claw screw 104, or when the claw screw 104 is loosened, the relative swing between the wire clip and the fixing seat 200 can be realized.
The insulating rod 800 includes an upper section 802 and a lower section 801 detachably connected to the upper section 802, and the positioning shaft 400 is disposed at an upper portion of the upper section 802. Specifically, the upper part of the lower section 801 is provided with a concave jack, and the lower part of the upper section 802 is detachably inserted into the jack; after the lower part of the upper section 802 is inserted into the jack, the upper section 802 and the lower section 801 are connected in a suction manner through a magnetic attraction structure.
The bottom of the jack is provided with a magnet 803, the lower part of the upper section 802 is provided with an iron block 804, and when the lower part of the upper section 802 is inserted into the jack, the iron block 804 is connected with the magnet 803 in a suction way. By adopting the principle of instant attraction and separation between the iron block 804 and the magnet 803, the upper section 802 and the lower section 801 are quickly connected and separated, so that the aim that a single lower section 801 can be selectively disassembled and assembled with a plurality of upper sections 802 can be fulfilled.
The linkage structure comprises a driving rod 603 and a first connecting rod 602, the middle part of the first connecting rod 602 is hinged with the upper clamping jaw, the outer end of the first connecting rod 602 is hinged with the lower clamping jaw 102, the inner end of the first connecting rod 602 is hinged with the driving rod 603, and the driving rod 603 is connected to the positioning shaft 400; when the insulation rod 800 drives the positioning shaft 400 to move up and down, the driving rod 603 drives the lower clamping jaw 102 to move up and down relative to the upper clamping jaw 100 through the first connecting rod 602.
Thus, since the lower end of the driving rod 603 is movably connected to the positioning shaft 400, when the insulating rod 800 drives the positioning shaft 400 to move up and down, the driving rod 603, the first connecting rod 602, and the lower clamping jaw 102 are linked therewith.
The outer end of the first link 602 has a first connecting section extending to the lower part of the lower jaw 102, and the first connecting section is hinged to the lower part of the lower jaw 102, so that the first link 602 drives the lower jaw 102 to move up and down.
The upper wire clamp is connected with a second connecting rod 601, the inner end of the second connecting rod 601 is hinged with the upper wire clamp, and the outer end of the second connecting rod 601 is hinged with the lower clamping jaw 102. When the insulation rod 800 drives the positioning shaft 400 to move up and down, the driving rod 603 drives the first connecting rod 602 to move, the first connecting rod 602 drives the lower clamping jaw 102 to move up and down, and the second connecting rod 601 also moves synchronously, so that the first connecting rod 602 and the second connecting rod 601 synchronously drive the lower clamping jaw 102 to move up and down.
The outer side of the positioning shaft 400 is provided with a locking block which moves transversely relative to the positioning shaft 400, and a spring 303, wherein the spring 303 provides an axial locking force for the locking block. When the locking block abuts the positioning shaft 400, the locking block limits the positioning shaft 400 from moving up and down relative to the locking block. Therefore, after the lower clamping jaw 102 moves upwards to clamp the conducting wire or the copper bar, the locking block is abutted against the positioning shaft 400, so that the up-and-down movement of the positioning shaft 400 can be limited, and the problem that the conducting wire or the copper bar is separated out due to the downward movement of the lower clamping jaw 102 is solved; when the grounding wire device is required to be detached from the wire or the copper bar, the locking block is separated from the positioning shaft 400 in a butting manner, so that the positioning shaft 400 can move upwards, the lower clamping jaw 102 is driven to move downwards, and the wire or the copper bar is separated from being clamped.
The fixing seat 200 is connected with a threaded seat body 300 which moves up and down relative to the fixing seat 200 through rotation, the threaded seat body 300 is in threaded connection with the fixing seat 200, a longitudinal hole for a positioning shaft 400 to pass through and a transverse hole penetrating through the longitudinal hole are formed in the threaded seat body 300, the positioning shaft 400 can move longitudinally in the longitudinal hole, and the positioning shaft 400 and the threaded seat body 300 are circumferentially and relatively fixed; the locking piece has and wears to establish built-in section 302 in the transverse hole and expose at the external section 301 outside the transverse hole, and the built-in section 302 cover of locking piece is equipped with spring 303, and spring 303 drives the locking piece towards location axle 400 lateral shifting. When the built-in section 302 of the locking block abuts against the positioning shaft 400, the locking block limits the positioning shaft 400 from moving up and down relative to the screw base 300.
Thus, when no external force is applied to the external section 301 of the locking block, the spring 303 drives the internal section 302 of the locking block to abut against the positioning shaft 400 under the action of the spring 303, and the positioning shaft 400 is limited from moving up and down relative to the locking block; or, the external section 301 of the locking block can be driven, so that the locking block deviates from the positioning shaft 400 to move, the internal section 302 of the locking block is separated from the abutting joint of the positioning shaft 400, and at the moment, the positioning shaft 400 can move up and down relative to the locking block.
The fixed seat 200 is provided with a downward-arranged abutting block 201, the threaded seat body 300 is driven to rotate relative to the fixed seat 200 by rotating the insulating rod 800, and the external section 301 of the locking block is close to or far away from the abutting block 201;
when butt piece 201 with during the external section 301 butt of locking piece, drive location axle 400 through rotating insulator spindle 800 and rotate, butt piece 201 drive locking piece deviates from location axle 400 lateral shifting to make butt between locking piece and the location axle 400 or break away from.
