Abstract
The utility model relates to the technical field of levelling staffs, in particular to telescopic struts of a levelling staff, which is characterized in that a male and female taper fastener (1) is arranged in the middle of a staff body of the levelling staff and is provided with a hole for movably connecting with a connector (2) of the telescopic struts, the connector (2) penetrates into a socket body (4) through a bolt (3) and then is fixed by a gasket (5) and a nut (6), a groove is arranged from the middle of the bottom of the bolt (3) to a right side wall and is internally provided with a movable cardan shaft, the cardan shaft is provided with the other telescopic strut, and the two struts respectively extend to the floor at an included angle of 45 degrees and form a tripod support with the upright levelling staff. Compared with the prior art, the utility model has simple structure, novelty, safety and reliability, is convenient to use and easy to assemble and disassemble, can keep absolute stability of the staff during measurement, and fills the void that the levelling staffs in measurement industry are not provided with support instruments.
Description
Technical field
The utility model relates to the levelling staff technical field, is a kind of levelling staff telescopic strut specifically.
Background technology
For the topocentric elevation of high-precision measuring, precise leveling remains traditional observation procedure of present the best.He is except as the element task of setting up the unification of the motherland elevation system, for all kinds of topographic mappings and engineering construction provide elevation to start at the data, also be used to simultaneously study the earth shape and size, determine each phaopelagile discrepancy in elevation and inclination, the vertical component of obtaining modern crust movement, the theory of setting up earth gravity field and method and explore all kinds of problem in science such as analysis seismic activity trend.
Now respectively be equipped with one and hold ring with the both sides, middle part, the back side of scale, rely on the unsettled ring of holding of two hands to keep the vertical-horizontal state of blade to reach 20-30 second during measurement, be that the gauger sets up instrument therebetween, adjust angle, reading on the intact scale of observed and recorded, because scale lacks effective supplemental support, not only operation is hard, especially under the weather of blowing, more cannot say for sure to demonstrate,prove the stability of scale state.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can alleviate labour intensity, the stable levelling staff telescopic strut of increase that scale is controlled.
For achieving the above object, design a kind of levelling staff telescopic strut, comprise levelling staff, the chi body centre position that it is characterized in that levelling staff is provided with male and female and moves back and pull out buckle (1), male and female are moved back and are pulled out buckle (1) and be provided with hole and telescopic strut connector (2) and flexibly connect, it is fixing by packing ring (5) and nut (6) that described connector (2) penetrates socket (4) back by latch (3), be provided with internal thread hole (7) in the middle of the bottom of socket (4) and connect telescopic strut, centre, bottom to the right side wall of latch (3) is provided with a groove, be provided with movable universal shaft in the groove, universal shaft is provided with another telescopic strut, and two struts become 45 respectively.About angle stretch to be pulled to and land, constitute triangle confrontation system with upright levelling staff and support.
Socket (4) right side is the right cylinder of three-dimensional square smooth connection less than socket, is provided with top-down circular hole in the three-dimensional square, and cylindrical inner chamber is provided with internal thread hole and connects telescopic strut.
Latch (3) bottom is three-dimensional rectangle, and smooth connection is less than the rectangular right cylinder of solid above the three-dimensional rectangle, and the cylindrical left side is an external thread structure, is provided with packing ring and nut.
The utility model compared with prior art, and is simple in structure, novel, easy to use, safe and reliable, easily installs, dismantles, and can keep the absolute of scale in measurement, filled up and measured the blank that the industry levelling staff does not always have the supplemental support utensil.

Appointment Fig. 1 is a Figure of abstract
Embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
Expansion link is installed on the middle part of 2 meters long scales, angle about at 45 is respectively stretched to be pulled to and is landed towards a left side and towards the rear two struts then, locking and upright scale formation triangle tripartite confrontation again, mobile on demand again strut carries out the adjustment level, pin strut at last, can keep strut motionless.
The utility model is moved back by the connecting elements of the finished product telescopic tube of two cover φ 20*900, rubber footmuff, aluminium alloy and male and female and pulls out buckle and form, the connecting elements of aluminium alloy adopts the aluminium alloy extrusions of 20*20, one needs to put in sleeve pipe behind the car circle, can the assembling after boring and pincers processing of other end square.
