Abstract
The invention discloses an insulation spanner with the self-locking function. The insulation spanner comprises a handle and a spanner body. One end of the spanner body is connected with the handle. Two fixing openings are formed in the other end of the spanner body. A self-locking device is installed on one fixing opening. The insulation spanner has the advantages that the handle is made of insulation epoxy resin, the spanner can be electrified to emergently maintain devices, and therefore operation safety of emergency maintenance personnel is guaranteed. Besides, the self-locking device is installed on one fixing opening of the spanner body to lock a nut, a gasket and a spring cushion, so that parts are prevented from disengaging, great convenience is brought for constructors, and safety potential hazards caused by dropping of the parts are also avoided.
Description
Technical field
The present invention relates to a kind of fastened tools; Particularly relate to the Insulation spanner that a kind of power supply industry is used.
Background technology
The power equipment of power supply industry is due to quality problems, installation existing problems or the connection inappropriate technology of equipment itself, the connecting portion loose contact, ageing equipment, the problems such as heavy load can cause the conductor joint heating situation, in the process that equipment is overhauled owing to required by power load and the restriction of power off time, can not, to the timely interruption maintenance of defect equipment, can only adopt the mode of livewire work to process.
The ratchet spanner used in livewire work at present is hand held, and volume is little lightweight, simple to operate, but, owing to being that the altitude hot-line operation staff need to wear insulating glove, insulating glove can affect nut, turn and the spring pad of being affectedly bashful to a certain extent.
Summary of the invention
Technical problem to be solved by this invention is, providing a kind of can be fixed on part on Insulation spanner, and has the place lock function, Insulation spanner that can livewire work.
The technical solution adopted in the present invention is: a kind of Insulation spanner with self-locking comprises handle and wrench body; One end of described wrench body is connected with handle, and the other end of wrench body is two permanent openings; On a described permanent opening, self-locking device is installed.
Described self-locking device comprises spring and lock body; Be formed with groove on the outer peripheral face of described permanent opening, groove from the lower end of permanent opening from the superficial to the deep to upper end, the lower end of described lock body is installed with spring between the inboard outside with permanent opening, the upper end of lock body and permanent opening at grade, and to the inclination of permanent opening inboard.
The lower end of described lock body is formed with projection.
Described lock body is identical with the material of wrench body.
The material of described handle is insulating epoxy.
The invention has the beneficial effects as follows: because handle is selected insulating epoxy, spanner can chargedly be rushed to repair equipment, guarantees repair personnel's job safety; In addition, the permanent opening of wrench body is equipped with self-locking device, and nut, packing ring and spring pad are pinned, and prevents the part slippage, is very easy to the workmen, has also avoided part the caused potential safety hazard of falling simultaneously.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
As shown in Figures 1 to 4, the present invention, with the Insulation spanner of self-locking, comprises, handle 10 and wrench body 20; One end of described wrench body 20 is connected with handle, and the other end of wrench body 20 is two permanent openings; Be installed with self-locking device 30 on a described permanent opening.Described lock body 31 is identical with the material of wrench body 20; The material of handle 10 is insulating epoxy; Described self-locking device 30 comprises spring and lock body 31; Be formed with groove on the outer peripheral face of described permanent opening, groove from the lower end of permanent opening from the superficial to the deep to upper end, the width of groove is identical with the width of described lock body 31, be installed with spring between the inboard, lower end of lock body 31 and the outside of permanent opening, the upper end of lock body 31 and permanent opening at grade, and tilt to permanent opening is inboard; The lower end of described lock body 31 is formed with projection 32, and projection is convenient presses the in good time nut that unclamps clamping with hand; In permanent opening, after mounting nuts, packing ring and spring pad, spring is extruded and, to 31 1 reaction forces of lock body, makes the front end of lock body 31 clamp the placement object, has solved the operational inconvenience produced because dressing safety protective tools; In addition, handle 10 is insulating epoxy, and the rated voltage that dielectric strength is 4.5 times meets the rules requirement of preventive trial, has reached the requirement of livewire work specialty.
The present invention is owing to carrying out insulation processing to handle, and therefore, spanner can chargedly be rushed to repair equipment, has avoided interruption maintenance, has guaranteed repair personnel's job safety; The locking device that Wrench head is installed has effectively been avoided high-altitude part the caused potential safety hazard of falling.
It is worthy of note, protection scope of the present invention is not limited to above-mentioned instantiation mode, according to basic fundamental design of the present invention, still can realize purpose of the present invention; As long as those of ordinary skills are without the process creative work, the embodiment that can associate, all belong to protection scope of the present invention.
