Abstract
The utility model discloses a special wrench for a butterfly nut of a grounding terminal. The wrench comprises a casing pipe, wherein the inner diameter of the casing pipe is larger than the outer diameter of the butterfly nut; two oppositely arranged clamp grooves are formed in the bottom end of the casing pipe; the size of each clamp groove corresponds to that of each side wing of the butterfly nut; a through hole transversely penetrating through the casing pipe is formed in the upper part of the casing pipe; and a rod-shaped rotary handle is mounted in the through hole. The special wrench for the butterfly nut of the grounding terminal is simple in structure and convenient to use, and the butterfly nut can be conveniently dismounted and mounted; and during working, all that is required is to nest the side wings of the butterfly nut into the clamp grooves, then the butterfly nut can be mounted or dismounted by rotating the rotary handle, moreover, during a fastening process, the clamp grooves are directly matched with root parts of the side wings, and torque born by the side wings is obviously reduced, so that the side wing deformation can be avoided.
Description
Technical field
The utility model relates to a kind of electric construction tool, is specifically related to the extracting tool of a kind of ground connection termination.
Background technology
At electric power facility construction field, earth connection is the important measures that ensure workmen's personal safety, in order to guarantee the fastness of ground connection, normally the ground connection termination of earth connection is fastened on ground stud by connecting bolt and wing nut.Wing nut generally comprises the nut body that an outline is truncated cone-shaped, and the side of nut body is provided with two and is convenient to the flank of tightening and dismantling.Wing nut is carried out when fastening, and general way is to reverse the flank of wing nut with hand, and wing nut is slowly tightened, and carries out further fastening in the time tightening to a certain degree with shfting wrench again.In operating process, there is the problem of following two aspects: 1) use shfting wrench carry out fastening before, need to adjust the openings of sizes of shfting wrench, affect operating efficiency; 2) in fastening process, because moment of torsion is larger, the Root Stress of wing nut flank is comparatively concentrated, therefore easily occurs even fracture of distortion at the root of flank.
Utility model content
The utility model technical issues that need to address are to provide a kind of ground connection termination wing nut special spanner, and to solve in conventional art, operating efficiency is not high, nut flank holds yielding problem.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows:
Ground connection termination wing nut special spanner, comprise sleeve pipe, the internal diameter of sleeve pipe is greater than the external diameter of wing nut, the bottom of sleeve pipe offers two draw-in grooves that are oppositely arranged, the size of draw-in groove is corresponding with the size of the flank of wing nut, the through hole that is horizontally through sleeve pipe is offered on the top of sleeve pipe, and shaft-like rotary handle is installed in through hole; The through hole on described rotary handle and sleeve pipe top is matched in clearance, and one end of rotary handle is fixedly installed block, and the other end is provided with nut by external screw thread.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is as follows:
The utility model is simple in structure, easy to use, and by two draw-in grooves are set in one end of sleeve pipe, the other end arranges rotary handle, and the size of draw-in groove is corresponding with the size of wing nut flank, can realize easily the dismounting of wing nut.When work, only the flank cover of wing nut need to be installed in draw-in groove, then rotate rotary handle and can realize the installation or removal of wing nut, without replacing instrument, and in fastening process, draw-in groove directly coordinates with the root of flank, the moment of torsion that flank bears obviously reduces, and therefore can avoid the distortion of flank.The through hole on rotary handle of the present utility model and sleeve pipe top is matched in clearance, can adjust flexibly as required the size of moment of torsion in rotary course, more laborsaving when operation, flexible.One end of rotary handle is provided with block, and the other end is provided with nut, can avoid rotary handle from through hole, to come off in rotation process, has further improved efficiency of construction.
Accompanying drawing explanation
Fig. 1: perspective view of the present utility model.
Wherein: 1. sleeve pipe, 2. draw-in groove, 3. rotary handle, 4. block, 5. nut.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done further to describe in detail:
A kind of ground connection termination wing nut special spanner, as shown in Figure 1, comprises sleeve pipe 1, and the cross section of sleeve pipe 1 is annular, and the internal diameter of sleeve pipe 1 is greater than the external diameter of wing nut, and in the present embodiment, the internal diameter of sleeve pipe 1 is 30mm, and external diameter is 40mm, and length is 200mm.
The bottom of sleeve pipe 1 is offered 2, two draw-in grooves 2 of two draw-in grooves along circumference and is oppositely arranged, 180 ° of each intervals.The width of draw-in groove 2 is corresponding with the thickness of the flank of wing nut, and the height of draw-in groove 2 is corresponding with the height of the flank of wing nut, and in the present embodiment, the width of draw-in groove is 8mm, is highly 40mm.Sleeve pipe 1 upper lateral is offered through hole, and the length direction of through hole and sleeve pipe is perpendicular, and rotary handle 3 is installed in through hole.
Rotary handle 3 is shaft-like, and rotary handle 3 is matched in clearance with the through hole on sleeve pipe 1 top, and rotary handle 3 one end are fixedly installed block 4, and the other end is processed with external screw thread, and external screw thread one end of rotary handle is through through hole, then mounting nuts 5 on external screw thread.The cross section of block 4 is circular, and the cross-sectional diameter of block 4 is greater than the diameter of the through hole on sleeve pipe 1 top, in order to avoid rotary handle 3 to come off in through hole in rotary course.Nut 5 is hex nuts, its cross sectional dimensions is also greater than the diameter of sleeve pipe 1 top through hole, in the time using the utility model work, nut 5 is tightened, can avoid rotary handle to come off in through hole, when end-of-job, nut 5 be unclamped, rotary handle 3 can be taken out from through hole, so that carry.
