Abstract
The utility model belongs to measuring tools for geodesic survey, topographic mapping, engineering construction and the like, and particularly relates to a telescopic surveyor's pole which comprises a tip and a pole body having more than three sections and disposed on the tip. The surveyor's pole is characterized in that each section of the pole body is cylindrical, a self-locking structure is arranged between each two sections of the pole body, and a compass is disposed on the pole body. The surveyor's pole has the advantages that the surveyor's pole is simple in structure, convenient to use, long in service life and suitable for outdoor and severe work environments, labor intensity can be reduced for surveying and mapping personnel, and surveying and mapping cost is reduced.
Description
Technical field
The utility model belongs to a kind of survey instrument that is used for geodetic surveying, topographic mapping, engineering construction etc., particularly a kind of telescopic overcasting staff.
Background technology
The main in the market overcasting staff great majority that occur are the aluminium matter bar or the scalable aluminium matter bars of pegging graft with screw thread or elastic opening pipe; But these two kinds of mark posts in use have been proved to be and have had fatal defective: like the aluminium matter bar of pegging graft with screw thread or elastic opening pipe; Once screw thread when speckling with earth, just can not connect soon.And that elastic tube can connect because of the plastic yield of material is not firm, thereby causes the body of rod crooked.And for example telescopic aluminium matter bar, not only the big bending strength of the plastic yield of material itself is poor, and must increase locking member, thereby makes complex structure.
The utility model content
The purpose of the utility model just is to overcome the deficiency that exists in the above-mentioned prior art, and a kind of telescopic overcasting staff simple in structure, easy to use is provided.
As above design, the technical scheme of the utility model is:
A kind of telescopic overcasting staff comprises tiptoe and places the body of rod that is flexible shape more than the joint of three on the tiptoe; It is characterized in that every pole body is a right cylinder, have self-locking structure between every pole body, on the said body of rod compass is housed.
Have suppending hole on the said tiptoe.
Be installed with the suspension braces on the said suppending hole.
Said overcasting staff is processed by fiberglass.
The utility model has the advantages that: simple in structure, easy to use, long service life is fit to use under open-air and the bad working environment, and can alleviates mapping worker labour intensity, reduces the mapping cost.
Description of drawings
Fig. 1 is the outside drawing of the utility model.
Fig. 2 stretches out constitutional diagram for the utility model.
Fig. 3 is the vertical view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
As shown in the figure, a kind of telescopic overcasting staff, the body of rod 2,3,4 that can be flexible shape by tiptoe 1 and three joints is formed; Every pole body is a right cylinder, has self-locking structure between every pole body, and compass 5 is housed on the body of rod 2; The body of rod is when indentation, and people can distinguish direction easily, are convenient to field work; Have suppending hole 6 on the tiptoe, be installed with suspension braces 7 on this hole.This mark post uses fiberglass to process, thereby makes its weight be lighter than wooden greatly and aluminium matter bar, and bending strength strengthens than aluminium matter bar, and dielectric strength greatly improves.
