Three, summary of the invention
The purpose of this utility model provides a kind of spacing positioning support of simple in structure, highly versatile, and this spacing positioning support is applicable to the steady arm of different size, and mechanical property is good.
The purpose of this utility model is achieved through the following technical solutions:
A kind of spacing positioning support is characterized in that: it comprises anchor ear support, left anchor ear, right anchor ear and claw bolt, the described left and right sides that is used for being arranged on an end of anchor ear support with registration arm bonded assembly left side anchor ear and right anchor ear and lays respectively at the anchor ear support; Be used for being arranged on the other end of anchor ear support with steady arm bonded assembly claw bolt; Described left anchor ear comprises the installation sheet and the bolt that be used for fixing installation sheet suitable with registration arm; Left side anchor ear has identical structure with right anchor ear.
Flowed for guaranteeing to stablize in the utility model, improve the Applicable scope of part, on the anchor ear support, be provided with the position limiting structure that is used for regulating the steady arm amount of raising, by adjusting the amount of raising that position limiting structure can effectively be regulated steady arm, to adapt to the steady arm of different size, obtain steady current.
Described position limiting structure comprises the through hole that is arranged on the anchor ear support, regulates bolt and setting nut, regulate bolt and be installed in the through hole, and with the match amount of raising of incompatible adjusting steady arm of setting nut.
In the utility model, be arranged on the other end of anchor ear support by nut with steady arm bonded assembly claw bolt.
The utility model has been integrated the function of a plurality of parts, has improved the Applicable scope of part.Adopt the al-mg-si material, take the metal paattern forging process, the surface anode oxidation process is made, be applicable to steady arm is connected on the registration arm of Φ 48 or Φ 55, when mounted, registration arm passed installation sheet on left anchor ear and the right anchor ear, and fix with bolt, by regulating position limiting structure, can control raising of steady arm by actv., it is all right that locomotive is flowed.The utility model is applicable to the location of spacing steady arm of flute profile or the spacing steady arm of rectangle.Simultaneously, the utility model is furnished with current connector, prevents to produce spark, the scaling loss part.The utility model has reduced each pts wt, reduces the online pts wt of contact system, more helps the raising of the speed of a motor vehicle.
Compared with prior art, the utility model has the advantages that: 1, highly versatile, be applicable to that the registration arm of different size and steady arm are equal, and also in light weight; 2, adopt Forging Technology to make, avoided the defective that produces because of casting, mechanical property is good; 3, adopt to adjust position limiting structure, the amount of raising of effectively regulating steady arm, guaranteeing that locomotive is stable is flowed.
