Measuring cylinder and measuring glass overlook device

Abstract

The invention relates to a measuring cylinder and measuring glass overlook device. The hollow area of a hollow rubber suction cup is communicated with a groove base through an air inlet pipe in a right groove wall and an air inlet pipe in a left groove wall and penetrates through the groove base so as to be communicated with a vacuumizing device behind the groove base. A rubber magnetic thin film of the vacuumizing device is clamped between a shell and the groove base; an included angle of 45 degrees is formed between a mirror frame of an embedded mirror surface and the horizontal plane of a support grid, the embedded mirror surface is arranged in a scale mirror image device located between the right groove wall and the left groove wall, and a horizontal section of an L-shaped cantilever vertical needle is adhered to the center of the top of the mirror frame; the side surface of an outer ring of a joint bearing at the center of the plane of the support grid plane is fixedly welded to the support grid, a metal gravity ball with a rod is fixedly connected with the position under the outer ring, and an inner ring of the joint bearing is welded to an L-shaped cantilever of the groove base. During vacuumizing, the device is adsorbed to the side surface of a measuring cylinder or a measuring glass, when the L-shaped cantilever vertical needle is overlooked and only the horizontal section, overlapping with a mirror image, of the vertical needle is seen, vertical looking is achieved, mirror image values of scales can be read in an overlook mode, and side-looking reading is replaced.

Description

technical field [0001] The invention relates to a measuring cylinder and measuring cup, in particular to a measuring cylinder and measuring cup miniature overlooking reading device for experiments, which belongs to the technical field of measuring cylinder and measuring cup reading. Background technique [0002] Most of the measuring cylinders and measuring cups in current experiments require horizontal side-view readings. The reading process involves a series of actions such as turning the head, attaching the body, twisting the waist, etc., which is cumbersome and difficult to read accurately, especially for beginners, the side-view readings often have deviations. For this reason, patent announcement number CN103674155A discloses a kind of digital measuring cup, according to measuring cup bottom hydraulic pressure, combined with the liquid density of input, liquid volume is automatically displayed; method of reading. In view of the requirement that the density of the liqu...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the long-standing problem of inconvenient side-view readings when conventional measuring cups and measuring cylinders are used to measure liquid volume, and proposes a measuring cylinder that can be adsorbed on the side walls of the measuring cups and measuring cylinders to convert side-view readings into top-view readings. reader
