Description
Technical field
The utility model relates to a kind of measurement mechanism, particularly a kind of dial gauge for improving measuring accuracy.
Background technology
Dial gauge is the instruction class measurer that a kind of measuring accuracy is higher.In field of civil engineering, dial gauge is often used to the distortion of measuring structure.
It is generally coordinate dial indicator bracket to use together that existing dial gauge is measured, and sounding rod is directly placed in the sectional position that will measure, then reads measured value.But in use usually there is following problem:
During measurement plane, only cannot ensure that the sounding rod of dial gauge is vertical with measurement plane by range estimation, cause measurement result out of true.Especially, in model test, structure distortion itself is less, and measuring error can produce considerable influence.
Utility model content
The purpose of this utility model is to provide a kind of dial gauge for improving measuring accuracy, cannot ensure sounding rod brought measuring error problem vertical with measurement plane to solve when existing dial gauge is measured.
For achieving the above object, the utility model adopts following technical scheme:
For improving a dial gauge for measuring accuracy, comprise the dial gauge main body that the back side is provided with index dial, index dial center is provided with rotating shaft, and rotating shaft is provided with connecting link, and connecting link one end is provided with round leveling bubble, and the other end is provided with angle indicator.
Further, index dial is fixed in dial gauge main body.
Further, connecting link can rotate around the axis.
Further, rotating shaft is provided with hold-doun nut.
Further, dial gauge main body is provided with sounding rod, and sounding rod top is provided with measuring head.
Further, dial gauge main body is fixed on support.
Further, support forms by two poles are hinged.
Further, one end fixation measuring bar of support, the other end is fixed with magnetic bases.
Compared with prior art, the utility model has following useful technique effect:
A kind of dial gauge for improving measuring accuracy of the utility model, the dial gauge main body of index dial is provided with by the back side, index dial center is provided with rotating shaft, rotating shaft is provided with connecting link, connecting link one end is provided with round leveling bubble, the other end is provided with angle indicator, angle indicator is made to point to the corresponding graduation position of index dial by regulating connecting link, adjustment dial gauge main body, the bubble of circle leveling bubble is made to be placed in horizontal alignment circle, now connecting link is in perpendicular, angle now between connecting link and sounding rod is the angle between measured section and surface level, this device can realize sounding rod and measure cross section orthogonal arbitrarily, reach the object improving measuring accuracy, the utility model structure is simple, easy to use, be suitable for the measurement of multiple angles position.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As Figure 1-3, a kind of dial gauge for improving measuring accuracy, comprise dial gauge main body 4, index dial 5 is provided with at dial gauge main body 4 back side, index dial 5 is carved with 360 scales, index dial 5 is fixed in dial gauge main body 4, index dial 5 center is provided with connecting link 3 by rotating shaft 2, connecting link 3 one end is provided with round leveling bubble 1, the other end is provided with angle indicator 6, angle indicator 6 on connecting link 3 refers on index dial 5, connecting link 3 can 2 rotate around the shaft, rotating shaft 2 is provided with hold-doun nut 9, by degree of tightness nut fixed connecting rod 3, when preventing from measuring, connecting link 3 rotates, dial gauge main body 4 is provided with sounding rod 7, sounding rod 7 top is provided with measuring head 8, and dial gauge main body 4 is fixed on support 12-1, and its medium-height trestle 12-1 forms by two poles are hinged, one end fixation measuring bar 7 of its medium-height trestle 12-1, the other end is fixed with magnetic bases 12-2.As shown in Figure 4, circle leveling bubble 1 comprises the pallet 1-1 be fixedly connected with connecting link 3, and pallet 1-1 is provided with horizontal alignment circle, is freely movable bubble 1-2. in pallet 1-1
Below in conjunction with accompanying drawing, structural principle of the present utility model and use step are described further:
When measuring vertical direction distortion, circle leveling bubble 1 is placed in top, corresponding angle indicator 6 refers at 0 scale place, then regulates and makes bubble placed in the middle, fixed by connecting link 3 by hold-doun nut 9, then now sounding rod is vertically, can measure vertical direction displacement; When measuring horizontal direction distortion, by corresponding for rotating shaft 90-degree rotation pointer at 90 scale places, regulate and make bubble placed in the middle, then now sounding rod is level, can measure horizontal direction displacement; With when should measure oblique section distortion, rotating shaft is rotated corresponding angle.The utility model is particularly suitable for the measurement of multiple angles position.
