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 uses.
Background technology
The power equipment of power supply industry due to equipment itself quality problems, existing problems are installed or Joining Technology improper, connecting portion loose contact, ageing equipment, the problems such as heavy load can cause conductor joint heating situation, owing to benefiting from the restriction of electrical load requirements and power off time in the process of overhauling equipment, to the timely interruption maintenance of defect equipment, can not can only adopt the mode process of livewire work.
The ratchet spanner used in livewire work is at present hand held, and small in volume is simple to operate, but owing to being that altitude hot-line operation staff needs 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, provide one part can be fixed on Insulation spanner, and has auto-lock function, can the Insulation spanner of 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; A described permanent opening is provided with self-locking device.
Described self-locking device comprises spring and lock body; The outer peripheral face of described permanent opening is formed with groove, groove from the lower end of permanent opening from the superficial to the deep to upper end, be installed with spring between the lower end inside of described lock body and the outside of permanent opening, the upper end of lock body and permanent opening at grade, and tilt inside permanent opening.
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 insulating epoxy selected by handle, spanner can chargedly be rushed to repair equipment, ensures the job safety of repair personnel; In addition, the permanent opening of wrench body is provided with self-locking device, nut, packing ring and spring pad is pinned, and prevents part slippage, is very easy to workmen, it also avoid part simultaneously and to fall caused potential safety hazard.

Detailed description of the invention
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; A described permanent opening is installed with self-locking device 30.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; The outer peripheral face of described permanent opening is formed with groove, 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, spring is installed with between the lower end inside of lock body 31 and the groove of permanent opening outside circumference, the upper end of lock body 31 and permanent opening at grade, and tilt inside permanent opening; The lower end of described lock body 31 is formed with protruding 32, the nut unclamping clamping that protruding convenience hand pressing is in good time; In permanent opening after mounting nuts, packing ring and spring pad, spring is extruded and to lock body 31 1 reaction forces, makes the front end of lock body 31 clamp placement object, solves the operational inconvenience produced because dressing safety protective tools; In addition, handle 10 is insulating epoxy, and dielectric strength is the rated voltage of 4.5 times, meets the regulatory requirements of preventive trial, reaches 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, avoids interruption maintenance, ensure that the job safety of repair personnel; The locking device that Wrench head is installed effectively prevent high-altitude part and to fall caused potential safety hazard.
It is worthy of note, protection scope of the present invention is not limited to above-mentioned instantiation mode, and basic fundamental according to the present invention is conceived, and still can realize object of the present invention; As long as those of ordinary skill in the art are without the need to through creative work, the embodiment that can associate, all belongs to protection scope of the present invention.
