A Connector Type Level Measuring Instrument

Abstract

The invention discloses a communicating vessel horizontal measuring instrument, and belongs to the technical field of engineering measuring devices. The measuring instrument comprises two measuring units with the identical structure, and a hose communicated with the two measuring units, wherein each measuring unit comprises a housing, a base, a button, a tension spring, a thrust shaft, a push rod, a guide frame, guide rods, an end cover, a flexible connecting tube, an elastic locking rod, a friction plate, a spatial articulating ring, a spatial articulating tube, a pouring weight, a connecting rod and a measuring tube. According to the measuring instrument, the measuring tubes are in free states before measuring by the spatial articulating tubes and the spatial articulating rings, and the measuring instrument is locked by the elastic locking rods and the friction plates during measuring, so that the measuring tubes can always be in states perpendicular to a horizontal plane during measuring, and the measuring accuracy can be ensured.

Description

technical field [0001] The invention relates to a level measuring instrument, in particular to a connector-type level measuring instrument, which belongs to the technical field of engineering measuring devices. Background technique [0002] In the decoration project, it is necessary to measure the levelness of the ground when installing the floor, especially for the relative height between two points. Using high-precision laser measuring instruments can achieve the goal, but its cost is too high. A simple spirit level has limited measurement capabilities and cannot measure two points that are too close or too far apart. [0003] Existing level measurement generally adopts the measurement method of reference point or intermediary point, which is repeatedly repeated and repeated. Since there is no dedicated one-time direct measurement device, it is time-consuming and laborious, and the measurement error is large. Chinese patent discloses a "communicator type spirit level" (p...

[0003] The existing level measurement generally adopts the measurement method of the reference point or the intermediary point, which is repeated and repeated. Since there is no dedicated one-time direct measurement device, it is time-consuming and labor-intensive, and the measurement error is large.

Chinese patent discloses a "communicator type spirit level" (patent No. 92229117), which utilizes the level difference of the vertical fluid channel body in the left level and the right level to show the detected level difference, but Its structure is complicated and the cost is high
