Abstract

The utility model discloses a switch break off bar, comprising components such as a T-shaped head(1) and a support bar(3). The T-shaped head(1) is movably connected with the top of the support bar(3) through a bolt(2). The support bar(3) is formed by connecting an upper supporting pole(3a) with a lower supporting pole(3b). An elliptical axis(4) is arranged below the upper pole(3a). Two symmetrical semi-axis leathers(5) are arranged outside the elliptical axis(4). A supporting plate(6) is arranged at the bottom of the elliptical axis(4). A cavity(7) is arranged in the lower supporting pole(3b). The utility model adopts a structure of a plurality of supporting poles movably connected with each other, so that the utility model has the advantages of simple and reasonable structure and convenient operation. The T-shaped head adopts the structure of bolts movably connected with each other which is convenient for adjusting the angle and operating.

Description

A kind of brake pull-rod

Affiliated technical field

The utility model belongs to a kind of electrician's instrument, particularly relates to a kind of brake pull-rod.

Background technology

Patent Office of the People's Republic of China discloses the utility model patent of a key name for " brake pull-rod " on June 22nd, 1994, and application number is 93222956.5, and Granted publication number is CN2169911Y.This patented technology adopts many mope pole docking modes, and the upper end of each pole is provided with the screw rod nipple, and the lower end is provided with the nut nipple.During use, screw by the joint connection according to the length needs; Not the time spent, outward winding by joint.There is following deficiency in the brake pull-rod of this structure: operate numerous rope, and not portable; The T-head of upper end is fixed on the rod, and angle is single, and the scope of application is narrow.

Summary of the invention

The purpose of the utility model is to provide a kind of improved brake pull-rod, and it has overcome the above-mentioned deficiency of prior art, and telescopic is adjustable, and is easy to operate, applied range, and result of use is good.

For reaching above-mentioned purpose, the technical scheme that the utility model is taked is: the utility model comprises T-head, pressure pin etc., and it is characterized in that: T-head is connected in the top of pressure pin by the bolt activity; Pressure pin is to be formed by movable connection of upper rack posts and lower fulcrum bar, and the upper rack posts lower end is an elliptical shaft, and elliptical shaft is furnished with the semiaxis skin of two symmetries outward, and the elliptical shaft bottom surface is fixed with supporting plate, has cavity in the lower fulcrum bar.

The utility model is taked technique scheme, has following beneficial effect: pressure pin of the present utility model adopts goes up lower fulcrum bar activity draw bail, and it is simple and reasonable, and is easy to use.Time spent not, can be with in the upper rack posts retraction lower fulcrum bar inner chamber, time spent, upper rack posts is extracted out, during its lower end to lower fulcrum bar accent place, rotated the major diameter end in contact semiaxis skin that upper rack posts makes elliptical shaft, the semiaxis skin is expanded outwardly, thereby the accent of extruding lower fulcrum bar forms fastening force, and the two is fixed in together like this.Otherwise, rotate upper rack posts, make it enter the lower fulcrum bar inner chamber.In addition, T-head adopts bolt activity draw bail, is convenient to adjust its angle, makes it use more effective convenience.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in detail:

Fig. 1 is the utility model structure diagram.

Fig. 2 cuts open figure for Figure 1A-A.

Embodiment

By Fig. 1, Fig. 2 as can be seen: the utility model comprises T-head 1, bolt 2, pressure pin 3, elliptical shaft 4, semiaxis skin 5, supporting plate 6, and T-head 1 is connected in the top of pressure pin 3 by bolt 2 activities; Pressure pin 3 is to be formed by movable connection of upper rack posts 3a and lower fulcrum bar 3b, upper rack posts 3a lower end is an elliptical shaft 4, the elliptical shaft 4 outer semiaxis skins 5 of being furnished with two symmetries, and elliptical shaft 4 bottom surfaces are fixed with supporting plate 6, supporting plate 6 supports semiaxis skin 5, has the cavity 7 that holds upper rack posts 3a in the lower fulcrum bar 3b.Fastening for T-head 1 is connected with pressure pin 3, what slide fastener not, the contact-making surface of T-head 1 and pressure pin 3 were provided with interworking buckles line 8.Pressure pin of the present utility model can adopt the movable connection of a plurality of poles as required.
