Description
Technical field
The utility model is related to technical field of measuring equipment more particularly to a kind of Telescopic Fixed devices of prism bar and prism
Bar.
Background technology
Prism bar is the important tool that point three-dimensional coordinate or construction lofting are obtained in production measurement.Due to measured object
Height is that sight is easily blocked in various or a certain plane, therefore is frequently necessary to adjust the height of prism bar.Generally adopt
The adjusting of prism bar height is realized by the attachment device of bar and bar with two bars or more bars.
The used method for adjusting prism bar height is at present：Mobile jib and strut are realized using fixed iron hoop and screw
Connection, screw is screwed out outward, interior iron hoop is detached with strut, and strut can freely stretch；By screw precession inside, interior iron is squeezed
Ring, interior iron hoop are in close contact with bar, and strut is fixed.This method has the following disadvantages：1) after the frequent use of screw, screw thread holds
It is also easy to produce abrasion, horizontal compression can not be provided, strut is caused to be susceptible to sliding；2) screw is easily dropped and lost.
Application No. is《201420466912.3》's《A kind of Multifunctional measurement rod》By reserving bayonet on lower beam top, i.e.,
Clamp, the i.e. combination of spring and spring card slot, when the clamp of upper boom rises to the bayonet of lower beam is arranged in upper boom lower end in one circular hole
When position, spring card slot is popped up and on bayonet by the spring of clamp, to fixed upper lower rod position.There are following for this method
Disadvantage：1) position of bayonet and clamp is easily deviateed, hardly possible alignment；2) height of prism bar is only left two values, i.e., upper boom forces down value
With draw high value.
There is a kind of method adjusting prism bar height to be at present：The flexible of strut is realized by ebonite set and spring assembly
With fixation, which is mainly to drive the close contact of interior gum cover and strut to fixed strut using the elastic force of spring；Pass through
The outer gum cover of pressing, spring are extruded, and elastic hour, interior gum cover detaches to realize freely stretching for strut with strut.This side
Method although solve screw frequently use rear thread it is easy to wear, horizontal compression can not be provided, cause strut be easy sliding and
The problem of screw is easily dropped and lost, but the shortcomings that this method be：After frequent use, the flexibility decrease of spring can not provide
The contact surface of enough elastic force, gum cover and bar loosens, and causes upper boom sliding that can not fix.
