Abstract
A kind of levelling pole, install one additional in the bottom of levelling pole body and rotate foot pin flexibly, levelling pole and foot pin utilize turning axle and universal joint to combine, during application foot pin is loaded onto, the time spent is not unloaded, and has solved the particularly turning point needs during the extreme terrain measurement of the level of measurement of the level, and the person also needn't carry foot pin in addition to hold up the chi, improve work efficiency and measuring accuracy, reduced the burden of field survey work.
Description
Technical field:
The present invention relates to the measuring instrument tool, relate in particular to a kind of levelling pole.
Background technology:
The levelling pole that uses in the existing surveying work, major part is single or double (being commonly called as black flour and the red face) scale of straight-plate-type, when carrying out leveling work, owing to carry out the preceding chi rotation (measuring term) that next stop when observation needs a station moving spirit-leveling instrument turning point, read the black flour reading so that see, when third-class above measurement of the level, the rotation of levelling pole also will be carried out in same station, reads black flour and red reading with sight.Present measurement of the level, all be to hold up the chi people in hand, to carry a foot pin that can make the levelling pole rotation simultaneously, arrival needs earlier foot pin to be placed on the ground behind the place of turning point, again levelling pole is positioned over the rotation of carrying out ruler on the foot pin, the defective that this method exists is: (1) is when extreme terrain, on the abrupt slope as rivers and canals, the specific position of buildings etc., foot pin can't be placed; (2) hold up the chi people to carry ruler simultaneously and foot pin has increased burden undoubtedly, and foot pin is lost easily;
Summary of the invention:
The inconvenience of " turning point " when having the levelling pole measurement of the level now in order to overcome, foot pin can't be placed during extreme terrain, hold up the chi people to carry ruler simultaneously and foot pin increases burden, the defective that foot pin is lost easily, a kind of levelling pole is provided, the defective of existing levelling pole is solved, and the precision and the work efficiency of measurement of the level are improved.
A kind of levelling pole of the present invention includes levelling pole body, foot pin, foot pin turning axle, two bearings, pin, universal ball joint.Establish a hollow round hole in the bottom center of levelling pole body, each is inlayed and puts a bearing up and down in it, the foot pin turning axle be the coupling shaft of levelling pole and foot pin pass these two bearing centers according to these two bearings be supporter, groove around axle one circle is arranged on the foot pin turning axle, a pin pin is housed in the side of levelling pole, and to advance this groove up and down with restriction foot pin turning axle, the bottom of foot pin turning axle is established a universal joint and is combined with foot pin, when not needing to rotate foot pin pin is unloaded and foot pin can be lifted down.
The invention has the beneficial effects as follows: solved the particularly turning point needs during the extreme terrain measurement of the level of measurement of the level, improved work efficiency and measuring accuracy, the person also needn't carry foot pin in addition to hold up the chi, has reduced the burden of field survey work, simple in structure, be convenient to operation.
Description of drawings:
Accompanying drawing is a kind of levelling pole structural representation of the present invention.
1. levelling pole body, 2. bearing, 3. bearing, 4. foot pin turning axle, 5. pin, 6. universal ball joint, 7. foot pin.
Embodiment:
In the bottom of levelling pole body (1) hollow round hole is set, each is inlayed and puts a bearing (2) and bearing (3) up and down in it, foot pin turning axle (4) be the coupling shaft of levelling pole and foot pin pass these two bearing centers according to these two bearings be supporter, be carved with a groove on the foot pin turning axle (4) around axle one circle, a pin (5) pin is housed in the side of levelling pole, and to advance this groove up and down with restriction foot pin turning axle (4), the bottom of foot pin turning axle (4) has a universal joint to combine with foot pin (7), three unguiculuses are arranged at the bottom of foot pin (7), the placement of being convenient to the foot pin fast and stable is unloaded pin (5) foot pin turning axle (4) can be extracted out when not needing to rotate foot pin on the ground.
Claims (1)
1. levelling pole, include the levelling pole body, foot pin, the foot pin turning axle, two bearings, pin, universal ball joint, it is characterized in that: establish a hollow round hole in the bottom center of levelling pole body, each is inlayed and puts a bearing up and down in it, the foot pin turning axle be the coupling shaft of levelling pole body and foot pin pass these two bearing centers according to these two bearings be supporter, there is one on the foot pin turning axle around the axle groove in one week, a pin pin is housed in the side of levelling pole body advances this groove with the upper and lower displacement of restriction foot pin turning axle, the bottom of foot pin turning axle is established a universal ball joint and is combined with foot pin.
