Description

A kind of support device of level

Technical field

The utility model relates to a kind of support devices of level, belong to phospecting apparatus technical field.

Background technique

Level is the instrument for establishing horizontal line of sight measurement ground point-to-point transmission height difference, and principle is to be surveyed according to measurement of the level principle Height difference between amount ground point.Level main component has telescope, pipe spirit level (or compensator), vertical axis, pedestal, foot screw, It is divided into tilting level, automatic compensated level, laser level and digital level (also known as electronic level) by structure, presses Precision is divided into precision level and ordinary level.

In the prior art, level is usually to lie in a horizontal plane on pedestal, when need to level adjust the angle alignment to When measuring point, level adjusts level angle and inconvenience since there are biggish stiction between its supporting leg and pedestal.

Utility model content

The purpose of the utility model is to overcome the above-mentioned deficiencies in the presence of the prior art, and provide a kind of branch of level Support arrangement has the effect of that level facilitates rotation so as to adjust theta alignment measurement point, improves measurement efficiency.

The above-mentioned technical purpose of the utility model has the technical scheme that

A kind of support device of level, the chassis including support frame and for placing level, further includes pedestal and rotation Turn ball, the bottom of support frame as described above and the pedestal is hinged, and the cavity for screw insertion, institute are offered in the pedestal It states center chassis and is connected with the column being fixedly connected with the screw, the chassis is turned by the column and screw It is dynamic to be mounted on the base.

Through the above technical solutions, center chassis connects a column being fixedly connected with screw, and screw is embedded in , then can be using screw as rotation center rotating chassis in pedestal, level is placed on chassis, then can pass through rotating chassis Change the measurement angle of level, facilitates and level is adjusted according to the position of actual spot of measurement, so that the level is directed at survey rapidly Point is measured, measurement efficiency is effectively improved.

Further preferably are as follows: the upper surface of the pedestal is protruded on the surface of the screw, is offered on the screw Jack, the bottom of the column is chimeric to be inserted into the jack.

Through the above technical solutions, base upper surface is protruded on the surface of screw, and opens up on screw and be inserted into for column Jack, then chassis can be removed when usually storing between column and screw for removable structure from pedestal, be saved Parking space.

Further preferably are as follows: it is symmetrically arranged with two opposite limit plates on the surface of screw protrusion pedestal, two Limit plate offers the fixation hole through the column, is equipped with fixing bolt on the fixation hole.

Through the above technical solutions, column and screw are kept fixed by installing fixing bolt on fixation hole, thus Chassis when using level can be prevented to be easily separated from screw, stablizing for level is influenced and use.

Further preferably are as follows: limit hole is offered on the limit plate, and the gag lever post of L-type is inserted in the limit hole, The limiting slot of annular is offered on the pedestal, one end of the gag lever post is chimeric to be inserted into the limit hole, and the other end is chimeric It is inserted into the limiting slot.

Through the above technical solutions, open up limit hole on limit plate, the limiting slot of annular is opened up on pedestal, in limit hole and In limiting slot be inserted into L-type gag lever post, then the gag lever post of column two sides by limit plate can limit column can not swaying style, To make chassis that can only carry out the rotation on horizontal plane, the level helped to be placed on chassis keeps stabilization not slide.

Further preferably are as follows: the screw be in ellipsoid, the cavity in agree with the rotation ball surface and for Rotate the goose egg shape of ball rotation.

Through the above technical solutions, screw is the goose egg shape agreed with rotation ball surface in ellipsoid and cavity shape, Since the diameter of ellipsoid is different, thus make screw that can only carry out the rotation of horizontal direction, it is solid with screw so as to avoid Surely the chassis connected is toppled over, and is helped to maintain level and is stablized.

Further preferably are as follows: the chassis is equipped with the positioning component for being positioned to level, the positioning group Part forms the gesture surrounded to level and contradicts with the side surface of level.

Through the above technical solutions, positioning component is arranged on chassis, positioning component to level formed the gesture surrounded and with The side surface of level contradicts, then level fixation can be limited in a certain position and do not moved by positioning component, facilitates level The accurate measurement of instrument.

Further preferably are as follows: the positioning component includes the L-shaped movable plate of one piece of fixed plate and two pieces of cross sections, described Fixed plate is fixed on the chassis, and two pieces of movable plates are symmetrically mounted on the two sides of the fixed plate, the movable plate Fixing groove is offered on bottom and the chassis, is fixedly installed with positioning bolt in the fixing groove.

Through the above technical solutions, the front of level is first contradicted into fixed plate when level is placed on chassis, then Unscrew positioning bolt, two movable plates is close to level until contradicting the side surface of level, then positioning bolt is tightened admittedly It is fixed, it is fixed on movable plate on chassis, so that positioning be fixed to level.

Further preferably are as follows: the lateral circle surface on the chassis is equipped with a rotating push rod.

Through the above technical solutions, rotating push rod is arranged on the lateral circle surface on chassis, rotating push rod can be convenient survey crew It pushes chassis to be rotated, facilitates the angle of adjustment level to rapid alignment measurement point.

In conclusion the utility model has the following beneficial effects:

1. level is placed on chassis, then can pass through rotating chassis by being rotatablely installed a chassis on pedestal Come realize level measurement angle adjustment, so that level is directed at measurement point rapidly, effectively improve measurement efficiency；

2. positioning component is arranged on chassis, positioning component carries out clamping position to the level being placed on domain, from And making level not easy glide, measurement data is more accurate.
