Fig. 1 is a kind of structure chart of telescopic brake pull-rod of the present invention.
Fig. 2 is the partial enlarged drawing in Fig. 1 at A.
Fig. 3 is a kind of sleeve profile of telescopic brake pull-rod of the present invention.
Specific embodiment
As shown in Figure 1-Figure 3, a kind of telescopic brake pull-rod, including sleeve 1, screw rod 2, adapter sleeve 3 and installed part 4, institute
State one end inside top of sleeve 1 and be provided with screwed hole 5, sleeve 1 adopts engineering plastics injection mo(u)lding, specifically using Merlon
（PC）Both there is the intensity of similar non-ferrous metal, while and have both ductility and obdurability, its impact strength is high, uses iron hammer
Percussion can not be destroyed, and the transparency of Merlon is again fabulous, and can impose any coloring；Or can be using concrete using poly-
Phenylate has excellent combination property, is under long-term load, with excellent dimensional stability and protrusion the characteristics of maximum
Electrical insulating property, using wide temperature range, can in the range of -127～121 DEG C Long-Time Service.With excellent water-fast, resistance to vapor permeability
Can, product has higher tensile strength and shock strength, and creep resistance might as well..The one end of the screw rod 2 is located at through screwed hole 5
In sleeve 1, screw rod 2 is made using engineering plastics, specifically using polyamide（PA, popular name：Nylon）Due to unique low-gravity, height

There is gap between portion 8 so that the second lug boss 9 can be stuck in gap location, and the clamping position of the first lug boss 8 is in the same manner.The drawing
Hook 10 is integrally formed with installed part 4.The tup 11 is integrally formed with installed part 4.The top outer of the sleeve 1 is provided with rubber
Set 12.
Tup 11, drag hook 104 and installed part 4 adopt stainless steel moulding by casting.Austenitic stainless steel is specifically adopted, wherein
It is more than 18% containing chromium, also containing the element such as 8% or so nickel and a small amount of molybdenum, titanium, nitrogen.Good combination property, is resistant to medium rotten
Erosion.The conventional trade mark of austenitic stainless steel has 1Cr18Ni9,0Cr19Ni9 etc..The Wc of 0Cr19Ni9 steel<0.08%, grade of steel acceptance of the bid
It is designated as " 0 ".Contain substantial amounts of Ni and Cr in this kind of steel, make steel be at room temperature austenitic state.This kind of steel has good modeling
Property, toughness, weldability, corrosion resisting property and without magnetic or weak magnetic, corrosion resistance is preferable in oxidisability and reductant, is used for
Acid-resistant system, such as anti-corrosion container and equipment lining, conveyance conduit, the equipment part of resistance to nitric acid are made, is also acted as in addition not
The material of main part of rust steel clock and watch ornaments.Austenitic stainless steel typically adopt solution treatment, will steel be heated to 1050～1150 DEG C,
Then water-cooled or air-cooled, is organized with obtaining single phase austenite.
Beneficial effects of the present invention are：Screw rod one end of setting is located in sleeve through screwed hole, and rotating screw rod can adjust
Section stretched length of the screw, reaching can be with the effect of rope；The fixing screws of setting sequentially pass through adapter sleeve and installed part so that
Can dismantle between adapter sleeve and installed part, while the first lug boss and the second lug boss clamping can be defined so as to adapter sleeve and peace
