Abstract
The invention relates to a novel precise invar leveling staff. The novel precise invar leveling staff is provided with a prolate ruler with scales on the front surface; a handle is arranged on one side of the ruler; a leveling bubble is arranged at the back of the ruler; the upper part of the ruler is connected with a sliding sleeve capable of sliding up and down; and the sliding sleeve is positioned at the back of the ruler and is hinged with a reflecting mirror capable of adjusting an angle up and down. The novel precise invar leveling staff has a simple structure and convenient use; a user can conveniently align and calibrate the leveling bubble without lowering the head and can observe the conditions of a road surface and a surveyor on the opposite side at the same time to achieve timely communication; and measuring time is effectively saved and personal safety is ensured.
Description
Technical field
The present invention relates to a kind of invar staff, especially a kind of novel precise invar staff.
Background technology
The levelling pole of existing instrument of surveying and mapping, in measuring process, exist weak point, especially when aiming at leveling bubble, sight line can not have certain pitch angle perpendicular to leveling bubble, can produce error, and in the process of calibration bubble of bowing, can't see the situation of vehicle on surveyor and the road surface, not only waste Measuring Time, also there is potential safety hazard, for the work of survey crew brings many inconvenience.
Summary of the invention
In order to solve the problem that existing invar staff in use runs into, the present invention proposes a kind of novel precise invar staff, this levelling pole is simple in structure, easy to use, the user can face the place ahead and can conveniently calibrate leveling bubble under situation about need not bow, and can observe the situation on road surface and opposite surveyor's situation simultaneously, accomplish timely communication, effectively save Measuring Time, guarantee personal safety.
The technical solution adopted for the present invention to solve the technical problems is: this novel precise invar staff comprises ruler, air level, handle, slip cap and catoptron; This levelling pole has a front to have the prolate ruler of scale; The side of this ruler is equipped with handle, and the back side is equipped with air level, to make things convenient for mobile ruler and to adjust this levelling pole verticality; This ruler top is connected with the slip cap that can slide up and down; This slip cap is positioned at the back side of ruler, hinge is connected to the catoptron that can adjust angle up and down, face catoptron, promptly can under the situation of not bowing, the convenient correct level of observing steep, and the situation that can observe vehicle on surveyor and the road surface simultaneously, both save the time, improved the security in the work again.
The invention has the beneficial effects as follows: this novel precise invar staff is simple in structure, easy to use, the user can conveniently aim at leveling bubble under situation about need not bow, and can observe the situation on road surface and opposite surveyor's situation simultaneously, accomplish timely communication, effectively save Measuring Time, guarantee personal safety.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing 1 is the example structure synoptic diagram of this novel precise invar staff.
Among the figure, 1. ruler, 2. air level, 3. handle, 4. slip cap, 5. catoptron.
Embodiment
In the accompanying drawings, this novel precise invar staff comprises ruler 1, air level 2, handle 3, slip cap 4 and catoptron 5; This levelling pole has a front to have the prolate ruler 1 of scale; The side of this ruler 1 is equipped with handle 3, and the back side is equipped with air level 2, to make things convenient for mobile ruler 1 and to adjust this levelling pole verticality; This ruler 1 top is connected with the slip cap 4 that can slide up and down; This slip cap 4 is positioned at the back side of ruler 1, hinge is connected to the catoptron 5 that can adjust angle up and down, face catoptron 5, promptly can under the situation of not bowing, the convenient correct level of observing steep 2, and the situation that can observe vehicle on surveyor and the road surface simultaneously, both save the time, improved the security in the work again.
