Abstract
The utility model relates to a brake pullrod. The brake pullrod comprises an insulation support rod, a support member and a fastening steel wire, wherein the support member has a T-shaped support rod and a sleeve arranged below the T-shaped support rod, the sleeve is sleeved at a top end of the insulation support rod, a position which is on a circumferential wall of the insulation support rod and is near a top end face is provided with a first semi-circular ring slot, a position which is on an inner circumferential wall of the sleeve and corresponds to the first semi-circular ring slot is provided with a second semi-circular ring slot, the first semi-circular ring slot and the second semi-circular ring slot form a circular slot, an outer circumferential wall of the sleeve is provided with a guide hole communicated with the circular slot, and the fastening steel wire is inserted into the circular slot through the guide hole to form axial limit between the support member and the insulation support rod. According to the brake pullrod, as axial limit between the support member and the insulation support rod is formed through the fastening steel wire, and the support member can rotate freely, so the brake pullrod is more flexible and practical in practical use.
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, need respectively the cost payouts such as machining screw or use screw due to above-mentioned two kinds of connected modes, thereby, production cost is higher, and structure is comparatively complicated.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, and a kind of modern design, brake pull-rod simple in structure are provided.
for achieving the above object, the utility model adopts a kind of brake pull-rod, comprise insulation pressure pin and strutting piece and locking steel wire, described strutting piece has the tee T support bar and is arranged on the sleeve of described T-shaped support bar below, this sleeve set is on the top of described insulation pressure pin, on the circle wall of described insulation pressure pin, position near top end face offers the first semicircle annular groove, on the inner peripheral wall of described sleeve, the position corresponding with the described first semicircle annular groove offers the second semicircle annular groove, the described first semicircle annular groove and the second circular draw-in groove of semicircular rings flute profile, offer the guide hole that is communicated with described circular draw-in groove on the outer circle wall of described sleeve, described locking steel wire interts into described circular draw-in groove by guide hole, and then form strutting piece and the axial limiting of the pressure pin that insulate.
Concrete, described sleeve is fixedly connected on described T-shaped support bar below by the mode of welding.
The utility model is by the above-mentioned improvement to prior art, owing to adopting locking steel wire to intert the axial limiting that forms insulation pressure pin and strutting piece into the mode of circular draw-in groove, and strutting piece can rotate freely, make brake pull-rod not only reach effect novel in design, simple in structure, and seem in actual use practical more flexibly.
