Description
Technical field
the utility model relates to a kind of mapping levelling staff balance and stability F type foot rest, belongs to mapping equipment field.
Background technology
in levelling practice, for obtaining high-precision measurement of the level observed reading, must ensure to survey and draw the balance and stability of levelling staff during the strict placed in the middle and long-time observation of leveling bubble on levelling staff.Current mapping worker is when carrying out levelling practice; mapping levelling staff need maintain vertically by the hand steered adjustment of vertical chi person; because leveling work environment is outdoor; under severe weather conditions; due to the factor with people self of blowing of wind; levelling staff often rocks, and causes larger error in leveling, and vertical chi person needs to consume the vertical of the firm scale of great effort simultaneously.Current levelling practice generally needs two vertical chi persons, and this working method not only causes the significant wastage of manpower, also add job costs.
Utility model content
in order to solve the problem, the utility model provides a kind of mapping levelling staff balance and stability F type foot rest, can realize surveying and drawing the balance and stability of levelling staff and the strict placed in the middle of leveling bubble, the effective mapping levelling staff that reduces rocks the error caused, and improves the precision of measurement of the level.
the utility model is achieved through the following technical solutions: a kind of mapping levelling staff balance and stability F type foot rest, comprises reversed F-typed support, supporting leg and terminal pad; Described supporting leg and reversed F-typed support circumference are distributed in around terminal pad; Described supporting leg and terminal pad hinged, described reversed F-typed support is fixedly connected with terminal pad; The horizontal lever front end of described reversed F-typed support is equipped with the fixed frame can fixing levelling staff, and fixed frame is provided with fixed knob.
described supporting leg is Collapsible structure, comprises fixed bar and expansion link, and the junction of described expansion link and fixed bar is provided with tightening knob.
described supporting leg at least arranges two.
the bottom of described expansion link is sharp cone distal.
described expansion link bottom is provided with the accessory pedal that supporting leg is inserted underground by convenience pin.
described fixed bar is connected with terminal pad by rotary joint.
described fixed frame is rectangle shape on one side less, and its base and reversed F-typed support welding, its at least one side is provided with threaded hole, and described fixed knob is rotatably connected with threaded hole.
the beneficial effects of the utility model are: a kind of mapping levelling staff balance and stability F type foot rest, and its simple structure is simple to operate, easy to use; With low cost, be easy to promote; The balance and stability surveying and drawing levelling staff can be ensured, can error in leveling be effectively reduced.
