Abstract
The utility model discloses an eccentric sleeve compressor. The eccentric sleeve compressor is characterized by comprising an outer sleeve and a handle which are fixedly connected together. An inner hole is formed in the middle of the outer sleeve, and contraction cavities are formed in the wall of the outer sleeve. The eccentric sleeve compressor further comprises shrink bolts. Threads matched with the shrink bolts are machined on the contraction cavities. The eccentric sleeve compressor has the advantages that the eccentric sleeve compressor is especially designed for adjustment of positions of an eccentric sleeve, when the shrink bolts are tightly abutted against the eccentric sleeve, the positions of the eccentric sleeve can be changed by rotating of the handle, and when the adjustment is finished, the eccentric sleeve is retracted from the compressor through the manners of knocking and shaking. Operation is simple, labor is saved, the adjustment is convenient, adjustment accuracy is high, and the eccentric sleeve compressor is a special tool which is reasonable in design.
Description
Technical field
The utility model relates to railway attachment technique field, especially relates to a kind of eccentric bushing deflation device of adjusting railway switch tongue gap length by rotating eccentric sleeve.
Background technology
The position of eccentric sleeves is the important method of regulating switch closure, when eccentric bushing position varying in size of tongue gap simultaneously not, suitable tongue, stock rail gap are the assurances that improves line quality, realizes traffic safety, and the change of eccentric bushing position can realize by rotating eccentric sleeve.In the prior art, the adoptable instrument of rotating eccentric sleeve is the arc pressing tongs, uses this tool operation time long, very easily causes the damage of the person and equipment in the use procedure, and it is low to adjust precision, can't satisfy the needs of construction precision.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, provide a kind of simple in structure, flexible and convenient to use, time saving and energy saving eccentric bushing tightens device, it holds out against the eccentric bushing of adjusting by tightening bolt, finish the adjusting of eccentric bushing position by turning handle, the technical scheme that adopts is: a kind of eccentric bushing tightens device, comprise the overcoat and the handle that are fixed together, have endoporus in the middle of the described overcoat, have shrinkage cavity on the overcoat wall, it is characterized in that: described eccentric bushing tightens device and also comprises and tighten bolt, is processed with in the described shrinkage cavity with described and tightens the screw thread that bolt matches.
Technical characterictic of the present utility model also has: in the middle of the described overcoat, a side of endoporus is provided with the eccentric bushing saddle.
The beneficial effects of the utility model are: the utility model aims at the adjustment of eccentric bushing position and designs, after tightening bolt and holding out against eccentric bushing, turning handle can be finished the change of eccentric bushing position, after adjusting is finished, by unscrewing eccentric bushing deflation bolt mode eccentric bushing is withdrawed from from tighten device, simple to operate, safety labor-saving, easy to adjust and precision is high, be a kind of special tool reasonable in design.
Description of drawings
Accompanying drawing 1 is the utility model front view, and accompanying drawing 2 is left views of accompanying drawing 1, and wherein 1 is to tighten bolt, the 2nd, and handle, the 3rd, overcoat, the 4th, eccentric bushing saddle, the 5th, shrinkage cavity, the 6th, endoporus.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.The utility model discloses a kind of eccentric bushing and tighten device, comprise the overcoat 3 and the handle 2 that are fixed together, have endoporus 6 in the middle of the overcoat 3, have shrinkage cavity 5 on the overcoat wall, the number of shrinkage cavity 5 can be more than one, be provided with 4 shrinkage cavities 5 in the present embodiment, be processed with and the screw thread that tightens bolt 1 and match in shrinkage cavity 5.An axial side of endoporus 6 is provided with the eccentric bushing saddle 4 to eccentric bushing axial location to be adjusted in the middle of the overcoat 3, and wherein, the axial dimension of overcoat 3 generally can be less than the axial dimension of eccentric bushing to be adjusted.
During use, eccentric bushing to be adjusted is inserted in the endoporus 6, after being in place, the axial location in tightening device is finished in the effect that eccentric bushing can be subject to eccentric bushing saddle 4.To tighten bolt 1 and be screwed in the shrinkage cavity 5, hold out against eccentric bushing, rotatable handles 2 is finished the adjusting to the eccentric bushing position subsequently, adjust complete after, unscrew and tighten bolt 1 and eccentric bushing is tightened the device from eccentric bushing easily withdraw from, finish this Adjustment operation.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model also is not limited only to above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also belong to protection domain of the present utility model.
