Description
Technical Field
The utility model relates to the field of electric power safety tools, in particular to a multi-angle grounding rod convenient to operate.
Background
When an electric power system is overhauled, a bus needs to be grounded so as to ensure the safety of maintenance personnel, a grounding wire clamp provided with a grounding wire is usually adopted to reliably clamp the bus to realize the grounding purpose, the conventional double-clamp grounding wire clamp has a fixed angle, the bus cannot be locked by the grounding wire clamp when the bus arranged in the vertical direction of the electric power system is grounded, and the bus falls off in work to cause high-voltage induction electric shock accidents of constructors. Patent document CN210318230U, entitled "universal transmission rotating mechanism of ground rod" discloses a ground rod with multiple angle adjustment, which is convenient for multiple angle grounding operation, however, this structure has the following problems in practical use: it needs to be in advance through operation locking mechanism, angle regulation, locks after adjusting the angle, then will operate locking mechanism once more when using the angle to mismatch the angle regulation once more, therefore the operation is more loaded down with trivial details.
Disclosure of Invention
The utility model aims to solve the problem of complex operation in actual use of CN210318230U and provide a multi-angle grounding rod convenient to operate.
The specific scheme of the utility model is as follows: the utility model provides a multi-angle earth bar of convenient operation, includes fixed chuck, and fixed chuck one side is equipped with the opening, and the screw rod that a vertical direction was arranged is equipped with at fixed chuck bottom middle part, screw rod and fixed chuck threaded connection, and the screw rod top is rotated and is connected with movable chuck, and the screw rod bottom is connected with an insulating bar through the universal joint, and the outside cover of universal joint is equipped with a supporting spring, supporting spring's both ends respectively with the both ends fixed connection of universal joint.
The universal joint adopts a cross universal joint.
The universal joint adopts a three-joint type cross universal joint which comprises an upper joint, a middle joint and a lower joint, wherein the bottom end of the upper joint is connected with the top end of the middle joint through the cross universal joint, the bottom end of the middle joint is connected with the top end of the lower joint through the cross universal joint, the bottom end of the lower joint is fixedly connected with an insulating operating rod, and the top end of the upper joint is fixedly connected with the bottom end of a screw rod.
The inner side of the fixed chuck is provided with a limit slideway which is arranged in the vertical direction, and one end of the movable chuck is provided with a positioning groove matched with the limit slideway.
The upper end of the opening side of the fixed chuck is provided with a limiting baffle plate which extends downwards.
The working process of the utility model is as follows: the movable chuck is adjusted to a proper position, so that the opening between the movable chuck and the fixed chuck is proper in size, a cable can be conveniently buckled in the opening, then the lower end of the insulating operating rod is held by hand, the cable is buckled in the inner side of the fixed chuck, then the insulating operating rod is rotated, the movable chuck is driven to move through the screw rod, and clamping is realized, and due to the fact that the universal joint is arranged between the insulating operating rod and the fixed chuck, operation can be carried out at any angle in the rotating and clamping process; the universal joint has certain supporting force through the supporting spring, and the phenomenon that the universal joint is inconvenient to buckle into a cable due to the fact that the universal joint sags under the action of the weight of the fixed chuck is avoided.
The utility model has the following advantages: the angle can be adjusted at will in the operation process, the operation is more convenient, and the operation efficiency is improved.
