Description
Technical field
A kind of levelling rod righting fixing device is the utility model is related to, belongs to engineering survey fixture fields.
Background technology
Levelling rod is the scale for being used for height difference measuring in the measurement of the level, has to ensure to be in constantly in use
Vertical state, at present, chi is mainly helped for a long time by manually helping chi to be at vertical state in leveling process
The fatigue of operating personnel is easily caused with walking, and it is difficult to ensure that the stabilization of levelling rod, can thus influence measurement result
Precision.
Utility model content
The purpose of this utility model is the deficiencies in the prior art to be solved, there is provided dress is fixed in a kind of levelling rod righting
Put.
The utility model is achieved through the following technical solutions：
I.e. a kind of levelling rod righting fixing device, including clamping rings and for support four of clamping rings it is flexible
Bar, expansion link are provided with clamping screw, and levelling rod is located in clamping rings, and slewing circle is provided with by bearing in clamping rings
Ring, rotate annulus upper end and square positioning Fang Huan is fixedly connected with by connecting rod, position on the relative two sides of Fang Huan
Screwed hole is offered, is provided with puller bolt through screwed hole, the front end of puller bolt, which is fixed with, holds out against ball, holds out against ball and is provided with
Pressing tight plate, hold out against ball and form universal joint with pressing tight plate.
Levelling rod is fixed by two universal joints, positioned through rotating annulus and positioning Fang Huan, levelling rod by
Vertical state is kept at any time in gravity, ensure that the accuracy of measurement, and is rotated conveniently, greatly reduces operating personnel
Labor intensity.
Further preferably, a handle is equipped with each Retractive leg, it is more square when adjusting the length of Retractive leg
Just, fast.
Further preferably, the Retractive leg lower end is hingedly connected with supporting plate, and the setting of supporting plate causes the utility model
Place more stable on the ground, it is ensured that the accuracy of measurement.
Compared with prior art, beneficial effect possessed by the utility model is：
1st, levelling rod through rotation annulus and positions Fang Huan, and is fixed, positioned, levelling rod by two universal joints
Because gravity keeps vertical state at any time, the accuracy of measurement is ensure that, and is rotated conveniently, greatly reduces operator
The labor intensity of member.
2nd, a handle is equipped with each Retractive leg, it is more convenient, fast when adjusting the length of Retractive leg.
3rd, Retractive leg lower end is hingedly connected with supporting plate, and the setting of supporting plate causes the utility model to place on the ground more
Add stabilization, it is ensured that the accuracy of measurement.

Embodiment
Below against accompanying drawing, specific embodiment of the present utility model is described in further detail.
A kind of levelling rod righting fixing device as shown in Figure 1 to Figure 3, including clamping rings 2 and for supporting fixation
Four expansion links 3 of annulus 2, a handle 12 is equipped with each Retractive leg 3, clamping screw 4 is additionally provided with Retractive leg 3, stretches
The lower end of contracting leg 3 is hingedly connected with supporting plate 13, and levelling rod 1 is located in clamping rings 2, is provided with clamping rings 2 by bearing 5
Annulus 6 is rotated, the upper end of annulus 6 is rotated and square positioning side's ring 8 is fixedly connected with by connecting rod 7, the side's of positioning ring 8 is relative
Two sides on offer screwed hole, be provided with puller bolt 9 through screwed hole, the front end of puller bolt 9, which is fixed with, holds out against ball
10, hold out against ball 10 and be provided with pressing tight plate 11, hold out against ball 10 and form universal joint with pressing tight plate 11.
The course of work：
In use, first the utility model is transported in specified location, four Retractive legs 3 are stretched out according to the landform on ground and arrived
Certain length so that levelling rod 1 is passed through probably on a horizontal position and rotate annulus 6 and positioning side by clamping rings 2
Ring 8 is placed, and by the bottom surface of levelling rod 1 as far as possible close to ground, rotates two puller bolts 9, pressing tight plate 11 holds out against the two of levelling rod 1
Side, the moment keeps vertical state to levelling rod 1 under gravity, finally, makes water by the length for finely tuning four Retractive legs 3
The bottom surface of object staff 1 just contacts bottom surface, in measurement process, when needing to convert the angle of levelling rod 1, it is only necessary to rotational positioning
The square can of ring 8 is completed, and is rotated convenient, fast.
