Problems solved by technology

As a high-precision instrument, the dissolution apparatus is prone to displacement of the blue (pulp) of the dissolution apparatus during long-term use of the rotation axis, which affects the normal use of the instrument.
Since the dissolution chamber of the dissolution apparatus is covered when it is running, forming a closed container, in order to know the displacement of the blue (pulp) of the dissolution apparatus in time, the conventional design of the dissolution apparatus uses a fixed-height ring to correct the dissolution The distance between the lower edge of the blue (pulp) and the bottom of the dissolution vessel is cumbersome and inefficient

Embodiment 1

[0031] according to figure 1 As shown, the present invention provides a displacement measuring device, comprising a base 1 and a moving needle, the base is a semicircular sphere with an open top, and a soft solid filler 4 is provided in the base 1, and the soft solid filler 4 is plasticine, and the bottom end of described moving needle is vertically arranged in plasticine.

[0032] When the base is a semicircular sphere with an opening at the top, since the semicircular sphere is equipped with plasticine, the displacement measuring device is essentially in the shape of a tumbler. When measuring a container with an arc-shaped bottom, the displacement measuring device can automatically find the container by using the principle of gravity of the tumbler Central location for easy measurement.

[0033] Further: the moving needle includes a needle cap 2 and a needle 3, the needle cap 2 is flat or curved, and the shape of the needle cap 2 can be selected arbitrarily according to the...

Embodiment 2

[0040] according to figure 2 As shown, the present invention provides a displacement measuring device, comprising a base 1 and a moving needle, the base is a cuboid with an open top, and a soft solid filler 4 is provided in the base, and the soft solid filler 4 is Plasticine, the bottom end of the moving needle is vertically set in the plasticine.

[0041] When the base 1 is a cuboid with an open top, since the base 1 of the cuboid is provided with plasticine, in the flat bottom container with a certain depth, the displacement measuring device should not be dumped to facilitate measurement.

[0042] Further: the moving needle includes a needle cap 2 and a needle 3, the needle cap 2 is flat or curved, and the shape of the needle cap 2 can be selected arbitrarily according to the shape of the contact surface of the object to be measured.

[0043] Further: an anti-slip layer is provided on the outer surfaces of the four sides of the base, so that it is not easy to slip when the...

Abstract

The invention discloses a displacement measuring device and a measuring method, which include a base and a moving needle, the base is provided with a soft solid filler, the bottom end of the moving needle is vertically arranged in the soft solid filler, the The moving needle can move in the soft solid filling. The invention discloses a method for measuring the displacement of an object in a closed container by a displacement measuring device, which can accurately measure the displacement of the object in the closed container.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a displacement measuring device and a measuring method. Background technique [0002] At present, many experiments need to be carried out in isolation, and various operations are performed on experimental objects in closed containers. However, during the long-term operation of the instrument, the components in the instrument often have a certain displacement, which will affect the normal use of the instrument, and the data will deviate. This requires timely understanding of the displacement of the components. Since the parts to be tested are isolated by containers, traditional contact measurements such as calipers cannot be realized, and non-contact measurement methods are required. [0003] Among them, the dissolution tester is a special instrument for the dissolution test of drugs. The Chinese Pharmacopoeia clearly stipulates the technical parameters of the dissolution test. One of ...
