Description
Technical field
The utility model relates to a kind of surveying instrument, relates in particular to a kind of angle surveyor's staff.
Background technology
Existing angle surveyor's staff comprises surveyor's staff chi body and bevel protractor chi body, one end of surveyor's staff chi body and bevel protractor chi body is hinged by jointed shaft, the outer end of jointed shaft is provided with locking knob, by locking knob level of compression chi chi body with surveyor's staff chi body and bevel protractor chi body, when launching because locking knob and surveyor's staff chi body have friction force, locking knob can be with the expansion of bevel protractor chi body further with level of compression chi chi body, the long-term compressing surveyor's staff chi cognition of locking knob makes surveyor's staff chi body deformability so on the one hand, deviation appears in the precision that causes measuring, bevel protractor chi body draws difficulty in owing to further locking also can cause the angle surveyor's staff after expansion on the one hand in addition, uses very inconvenient.
Summary of the invention
In order to solve the technological deficiency that above-mentioned bevel protractor locking mechanism exists, the purpose of this utility model provides a kind of digital display angle surveyor's staff, and this bevel protractor surveyor's staff has simple in structure, easy to use, the characteristics that measuring accuracy can not change.
In order to realize above-mentioned technical purpose, the utility model has adopted following technical scheme:
A kind of digital display angle surveyor's staff, this bevel protractor comprises surveyor's staff chi body and bevel protractor chi body, one end of surveyor's staff chi body and bevel protractor chi body is hinged by articulated mounting, surveyor's staff chi body is provided with bubble and digital display screen, described articulated mounting comprises jointed shaft and locking knob, one end of jointed shaft is fixedly installed on the bevel protractor chi body, the other end of jointed shaft passes surveyor's staff chi body and connects with surveyor's staff chi body is movable, the outer end of jointed shaft links by screw thread and locking knob, surveyor's staff chi body is provided with mounting hole, locking knob covers on the mounting hole, in mounting hole, be provided with spring, spring is located on the jointed shaft, and the inner of spring and mounting hole bottom surface offset, and the outer end and the locking knob of spring offset.
As preferably, above-mentioned mounting hole bottom surface is provided with first packing ring, and the inner of described spring and first packing ring offset, and the inboard of locking knob is provided with second packing ring, and the outer end of described spring and second packing ring offset.
As preferably, the excircle that above-mentioned bevel protractor chi body and surveyor's staff chi body are contacted is provided with ring groove, and is provided with the annular protrusion suitable with ring groove on surveyor's staff chi body.
The utility model is owing to adopted above-mentioned technical scheme, by spring is set in mounting hole, locking knob is not a direct contact water leveling ruler chi body, makes surveyor's staff chi body and the locking of bevel protractor chi body on the bottom surface of mounting hole but the power that screws is delivered to by spring.Locking knob can not contact with surveyor's staff chi body like this, and along with the expansion of bevel protractor chi body, locking knob can be followed bevel protractor chi body and be rotated, and has avoided further compressing surveyor's staff chi body.The utlity model has simple in structure, easy to use, the characteristics that measuring accuracy can not change.
