Abstract
The utility model discloses a novel lead end grounding clamp, which comprises a wire clamp main body, an auxiliary wire clamp, an operating lever and a transmission mechanism. The novel lead end grounding clamp combines and utilizes the operating lever, a crankshaft and connecting rod mechanism and a scissors mechanism to achieve wire clamp chuck journey enlargement so as to achieve purposes of decreasing of the spiral number and reducing of labor intensity. A chuck can be opened and closed as long as the operating lever is rotated, therefore clamping and loosening motion of a high voltage wire is completed rapidly. Thus, the novel lead end grounding clamp solves the problem that the rotation number of a traditional pure lead screw mechanism wire clamp is too much, enables construction operation to be simple and convenient, and can effectively reduce workload of testing personnel. In addition, the novel lead end grounding clamp further utilizes arc limit slots of an angle adjusting and positioning bolt and a sector plate to meet requirements for an adjustable angle between a wire clamp and the operating lever.

The utility model content
The technical problem that the utility model will solve provide a kind of rational in infrastructure, ground connection is reliable, simple to operate, novel conductive wire termination ground clamp that labour intensity is less.
Adopt following technical scheme for solving the problems of the technologies described above the utility model: novel conductive wire termination ground clamp; Comprise wire clamp main body, by-pass folder, joystick and transmission mechanism, wire clamp main body one end is a fanning strip, and the other end is the main line chuck; Middle by the connection of folder body; Have the circular arc stopper slot on the fanning strip, folder body top is installed with chute vertically, and folder body bottom is provided with earth connection point; The by-pass folder comprises by-pass chuck, push rod slide block and length adjustment screw rod, and the by-pass chuck is connected with length adjustment screw rod one end through revolute, and the length adjustment screw rod other end is connected with the push rod slide block through screw thread, and push rod slide block and chute are slidingly matched; Transmission mechanism comprises scissors mechanism and toggle; Scissors mechanism one end is connected through bearing pin with the push rod slide block; The scissors mechanism other end is fixedly connected with the crank end of toggle through the mandrel that is installed on the wire clamp main body through hole, and the connecting-rod head of toggle is connected through bearing pin with joystick; Fixing angle adjustment bolt by the lock-nut activity in the circular arc stopper slot, angle adjustment bolt and joystick are through being threaded.
The angle adjustment bolt comprises connecting rod and screwed hole, and connecting rod passes the circular arc stopper slot and can move along the circular arc stopper slot, and screwed hole is fixedly connected connecting rod and cooperates with the screw portion of joystick, and lock-nut cooperates with the screw portion of connecting rod.
5 degrees of freedom of chute restriction push rod slide block.
To the problem that traditional wire clamp exists, the utility model is reliable to contact, guarantee that safety is starting point, the novel conductive wire termination ground clamp of having used spiral self-locking and Designing Linkages.Under the situation that guarantees self-locking, the utility model combines and utilizes joystick, toggle and scissors mechanism, realizes that the amplification of wire clamp jaw travel reduces the purpose that the spiral number of turns reduces labour intensity to reach.As long as rotating joystick is expansible, closed chuck, thus accomplish fast high-voltage line clamping, unclamp action.So innovation has overcome the too much problem of traditional pure silk linkage wire clamp rotation number of turns, makes constructing operation easier, can effectively reduce testing staff's workload.In addition, the utility model also utilizes the circular arc stopper slot of angle adjustment bolt and fanning strip to satisfy the requirement of adjustable angle between wire clamp and the joystick.
