Abstract
The utility model discloses a rotatable nested formula ruler pad is by ruler pad spring, ruler pad base, put ruler groove, base calibration circle punch combination. Ruler pad's upper portion is provided with the ruler pad spring, can make things convenient for the leveling of levelling rod, there is the ruler groove of putting that can fix the levelling rod at ruler pad's middle part, that the ruler pad base adopts is rubber materials, can effectually avoid the corruption of rainwater, base calibration round hole is then improved the measuring degree of accuracy greatly. The utility model discloses simple structure, easy and simple to handle, portable can use in rainy day or wetland, and is not fragile, has greatly improved control measuring technique personnel's work efficiency, has reduced technical staff's work load.
Description
Technical field
This utility model patent relates to building engineering survey engineering field, particularly relates to a kind of rotatable nested type foot pin.
Background technology
Foot pin is the aid placing levelling rod during monitoring measure setup turning point, general foot pin is made up of the casting pig of triangle, center upper portion has the hemisphere of projection, the bottom of foot pin is arranged to three tip-angled shapes to be treaded in soil, when stabilizing it use, being treaded by foot pin, levelling rod stands on the hemisphere top of foot pin upper lobes with the help of monitoring survey crew.When levelling rod rotation direction, the elevation of foot pin will not change, reduce measurement error, facilitates measurement operation.But, owing to foot pin is made up of cast iron (pig iron), in the rainy day or when having hydrops local to place foot pin, foot pin can issue biochemical reaction in the effect of water, cause foot pin to get rusty, accumulate over a long period and will affect the correctness of measurement data.Furthermore, during measuring, when the turning point arranged or when drawing a little many, carrying of foot pin will result in the biggest inconvenience, and what hamper measurements worked is normally carried out.
Summary of the invention
In order to make up all deficiencies of the foot pin during monitoring is measured, this utility model provides a kind of rotatable nested type foot pin, and this utility model facilitates monitoring to a certain extent and measures the use of technical staff, substantially increases work efficiency.
It is a kind of rotatable nested type foot pin that this utility model solves the technical scheme is that this utility model of its technical problem, by foot pin spring, foot pin base, put chi groove, base calibration circular hole form.The material of foot pin uses waterproof rubber and makes, and what fixing ruler arranged at the top of foot pin puts chi groove, and the chi groove of putting of foot pin is positioned on spring member, and the bottom of foot pin uses the cuboid component of elastomeric material.
The beneficial effects of the utility model are: this design has simple in construction, easy to carry, improve measurement efficiency to a great extent, measure staff to monitoring and provide conveniently.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is foot pin front schematic view；
Fig. 2 is foot pin schematic top plan view；
Fig. 3 is foot pin elevational schematic view；
Reference: (1), foot pin spring；(2), foot pin base；(3) chi groove, is put；(4), base calibration circular hole.
Detailed description of the invention
In Fig. 1, a kind of rotatable nested type foot pin, by foot pin spring (1), foot pin base (2), put chi groove (3), base calibration circular hole (4) form.The middle part of foot pin spring (1) is provided with puts chi groove (3), and levelling rod is mainly placed in the effect putting chi groove (3), and the effect of foot pin spring (1) mainly facilitates the leveling of levelling rod；The bottom of foot pin is the base (2) of quality of rubber materials, and base uses elastomeric material, can effectively avoid the erosion of rainwater；There is the circular hole (4) fallen in of calibration in the bottom of foot pin base, improve the precision of measurement.
As improvement, the material of foot pin uses waterproof rubber and makes.
As improvement, the chi groove of putting of foot pin is positioned on spring member (1).
As improvement, the base (2) of foot pin uses the cuboid component of elastomeric material.
As improvement, what fixing ruler arranged at the top of foot pin puts chi groove (3).
Claims (2)
1. a rotatable nested type foot pin, it is characterized in that by foot pin spring (1), foot pin base (2), put chi groove (3), base calibration circular hole (4) form, the middle part of foot pin spring (1) is provided with puts chi groove (3), and bottom is provided with the base circular hole (4) of calibration.
A kind of rotatable nested type foot pin the most as claimed in claim 1, it is characterised in that described foot pin base (2) uses elastomeric material.
