Description
Technical field
The present invention relates to electric power tool correlative technology field, the release insulating bar of the adjustable anticreep of specifically a kind of axial length.
Background technology
Insulating bar is the insulating tool operated to charging equipment for the short time, is such as switched on or switched off high voltage isolator, dropping fuse tool etc..But, it is when the action bars of the operation of operating a switch to high voltage electric equipment is typically all regular length, not readily portable, for higher or longer-distance operation of operating a switch is accomplished by long action bars, and for, in small space, long action bars can not be used again, short operation bar can only be changed again.Also there is scaling operation bar at present, this action bars is made up of fix bar and motion bar, fastened using rotary fastening structure between fix bar and motion bar, make as fix bar and motion bar are pipe, in the course of time, as rotary fastening structure is by the way of screw threads for fastening, the situation that stripped thread occurs firmly is twisted, fixation is not firm after causing adjustment length；And in the installing of earthing clamp edge action bars, dismounting earth lead, due to lead it is too high, when during installing ground wire, insulating bar is difficult to separate with earthing clamp and remove ground wire, the easy high-altitude obscission of earthing clamp, cause earthing clamp to damage, nearby device and operator's person in falling process, can be made to be on the hazard.
The content of the invention
It is an object of the invention to provide a kind of release insulating bar of the adjustable anticreep of axial length, to solve the problems, such as to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme：
A kind of release insulating bar of the adjustable anticreep of axial length，Including lower insulation tube and upper insulation tube，The upper insulation tube lower end is plugged in lower insulation tube，The lower end of the upper insulation tube is internally provided with movable block，The lower end of the lower insulation tube is provided with fixed closure plate，The upper insulation tube is in axial direction symmetrically arranged with twice pilot hole，The lower insulation tube upper end is provided through the guide pad of pilot hole，The locating piece of collar plate shape is provided between two guide pads，Locating piece external diameter is less than lower insulation bore，Screw mandrel is rotatably connected between locating piece and fixed closure plate，Screw mandrel is passed through movable block and is threadedly coupled with movable block，Screw mandrel lower end is connected with the connecting rod below fixed closure plate，Connecting rod is vertical with screw mandrel lower end and is fixedly connected，The connecting rod outer end is vertically installed with handlebar，Handlebar is located on connecting rod，The locating piece upper surface is connected with the support block of collar plate shape，The circumferential surface of support block is uniformly provided with four spherical grooves，It is equipped with each spherical groove and rolls the ball being connected with upper insulation inside pipe wall；The upper end of the upper insulation tube is provided with chuck, the chuck includes U-shaped connecting rod, one end of the U-shaped connecting rod is shorter than the other end, one end of the length of the U-shaped connecting rod passes through spring and sleeve to be connected with the baffle plate that comes off, the external diameter of sleeve is matched with the internal diameter size of the release ring of ground clamp, gravitation ball is housed on the baffle plate that comes off, sleeve is connected with the flapper that comes off, short one end of U-shaped connecting rod is affixed with the middle part of head rod and the two is vertically arranged, the head rod is vertically arranged, one end of head rod is connected with one end of upper insulation tube, one horizontally disposed connecting plate is housed on the other end of head rod, sell equipped with the suppending hole with ground clamp matches first on the connecting plate.
As further scheme of the invention：Screw mandrel, lower insulation tube and upper insulation tube are arranged with centrage.
As further scheme of the invention：The fixed closure plate lower surface is circumferentially uniformly provided with two, and locating slots of pluggable cooperation corresponding up and down with handlebar.
As further scheme of the invention：Equipped with the second pin on the side wall of the head rod.
Compared with prior art, the invention has the beneficial effects as follows：Present configuration structure, simple to operate, regulation are laborsaving；During use, the baffle plate placement horizontal level that comes off will be prevented first, which is fixed into rear through mode earth lead release ring with pring trip gear, after release ring touches spring dropping device, the baffle plate Automatic-falling that comes off is placed, upright position is changed into from self gravitation effect, gently drawn after release ring with insulating bar, separate with wire, this pattern earth lead would not occur to depart from insulating bar phenomenon, so as to be threatened to operator safely；And when insulation tube in telescopic adjustment is needed, rotate handlebar, rotated by connecting rod drive screw, under the spacing stop of guide pad, the movable block being connected with wire rod thread drives upper insulation tube axial movement, that is, the pilot hole gone up on insulation tube to move axially along guide pad, thus easily quickly carries out the effect of axial length regulation to action bars, ball on support block circumferencial direction play support and feel relieved on insulation tube while, also function to reduce axial movement frictional force effect.After length is regulated, push up handlebar, handlebar upper end is entered in locating slot, there is frictional force, handlebar the grafting cooperation between locating slot, it may have frictional force between handlebar and connecting rod, so ensure that handlebar securely can be inserted in locating slot, as handlebar being positioned, thus screw mandrel can be maintained static by connecting rod, so that it is guaranteed that the length between upper insulation tube and lower insulation tube keeps stable.
