Abstract
The utility model relates to a brake pull-rod. The brake pull-rod comprises an insulating prop rod, pressure blocks, fastening screws, and a support member arranged at the top of the insulating prop rod, wherein the support member is provided with a T-shaped support bar and a sleeve arranged at the lower portion of the T-shaped support bar; the circumferential wall of the sleeve is provided with at least two installing holes and the sleeve is installed at one end of the insulting prop rod in a sleeved manner; one side of each pressure block is provided with an arc-shaped groove; each arc-shaped groove is adjacently arranged at the outer circumferential wall of the sleeve; each pressure block is provided with an axial through hole; and the fastening screws successively pass through the axial through holes of pressure blocks and the installing holes and are fixedly installed on the insulating prop rod. According to the utility model, the pressure blocks are arranged between the fastening screws, and the insulating prop rod and the arc-shaped grooves are arranged so as to enable the pressure blocks and the outer circumferential wall of the sleeve are adjacently arranged so that the screwing force of the fastening screws are more uniformly distributed on the insulating prop rod through the pressure blocks and the overall structure is more compact and reliable.
Description
Technical field
The utility model relates to a kind of electrician and uses operation tool, relates in particular to a kind of brake pull-rod.
Background technology
Those skilled in the art should know, brake pull-rod of the prior art comprises the insulation pressure pin and is fixedly installed on the T-shaped support bar of insulated holding masthead end, described T-shaped support bar often is threaded connection or the mode of at least two screw fastenings is arranged on described insulation pressure pin, when adopting a plurality of screws to carry out when fastening, fastening effect due to screw on circular side face is not fine, as easy as rolling off a log the relaxing of screw even comes off, and therefore embodies unreliable, the unsettled defect of brake pull-rod.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, and a kind of brake pull-rod of reliable and stable, compact conformation is provided.
For achieving the above object, the utility model adopts a kind of brake pull-rod, comprise the insulation pressure pin, pressure block, trip bolt, be fixedly installed on the strutting piece of this insulated holding masthead end, described strutting piece has the tee T support bar and is arranged on the sleeve of described T-shaped support bar below, offer at least two installing holes on the circle wall of described sleeve, and sleeve set is at an end of described insulation pressure pin, a wherein side of described pressure block has arc groove, the outer circle wall close neighbour of this arc groove and described sleeve arranges, and on this pressure block, offer axially extending bore with position corresponding on the axial direction of described installing hole, described trip bolt is fixedly mounted on the insulation pressure pin through axially extending bore and the installing hole on sleeve of described pressure block successively.
The utility model is by the above-mentioned improvement to prior art, owing between trip bolt and insulation pressure pin, being provided with pressure block, and the outer circle wall that makes pressure block and described sleeve by offering arc groove forms the close neighbour and arranges, and then make the screwing force of trip bolt be distributed on the insulation pressure pin by pressure block more uniformly, reach the more compact reliable effect of overall structure.
