Description

Sampling device for chemical industry specialty

Technical Field

The utility model relates to a sampling device for chemical industry specialty belongs to chemical industry specialty technical field.

Background

Need carry out the analysis experiment to some samples in the chemical industry specialty, this kind of analysis experiment is gone on in the laboratory usually, adopts rubber head burette when taking a sample to the liquid sample, and what rely on is that the suction that resumes the production behind the rubber ball deformation, if the dynamics of holding between the fingers is too big in the use, can lead to the unable recovery of rubber ball to can't carry out the imbibition, use inconvenient, to this, we propose a sampling device for the chemical industry specialty.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model overcomes current defect, provides a sampling device for the chemical industry specialty to solve the problem in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a sampling device for the chemical industry specialty, includes the pipette, pipette top fixedly connected with thread bush, thread bush threaded connection has the imbibition subassembly, the imbibition subassembly includes solid fixed ring, rolling disc, threaded rod, fly leaf.

Further, thread bush threaded connection is fixed the ring, fixed ring top is passed through the bearing and is rotated and connect the rolling disc, rolling disc central point puts and is equipped with the screw hole, screw hole threaded connection threaded rod, threaded rod bottom fixed connection fly leaf.

Further, the threaded rod surface is equipped with the spacing spout of vertical setting, just spacing spout passes through the solid fixed ring inner wall of spacing slider connection.

Further, the movable plate is arranged in the liquid suction pipe, and a sealing ring is arranged between the movable plate and the liquid suction pipe.

Furthermore, the pipette is provided with scale marks, and the outer surface of the rotating disc is provided with anti-skid lines.

The utility model has the advantages that: 1. by arranging the liquid suction assembly, the structure of the liquid suction assembly comprises a fixing ring, a rotating disc, a threaded rod, a movable plate and the like, after the bottom end of the liquid suction pipe is inserted into a liquid sample, one hand holds the fixing ring, the other hand rotates the rotating disc, and the threaded rod drives the movable plate to move upwards under the matching of threads and a limiting sliding groove, so that a cavity at the bottom of the movable plate in the liquid suction pipe is in a negative pressure state, the liquid sample can be sucked, and the liquid suction is more stable and effective compared with a rubber-head dropper;

2. the thread sleeve of the liquid suction pipe is fixedly connected with the liquid suction component in a threaded connection mode, so that the liquid suction component can be conveniently detached, the device can be conveniently cleaned, parts can be conveniently replaced and maintained, and the use of people is facilitated.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

As shown in fig. 1-3, a sampling device for chemical industry specialty, includes pipette 1, and pipette 1 is the transparent glass pipe, 1 top fixedly connected with thread bush 2 of pipette, thread bush 2 is used for swing joint imbibition subassembly to in the dismantlement of imbibition subassembly, 2 threaded connection of thread bush have the imbibition subassembly, the imbibition subassembly includes solid fixed ring 3, rolling disc 4, threaded rod 5, fly leaf 6.

Specifically, as shown in fig. 1, the pipette 1 is provided with scale lines, so that the amount of the liquid to be taken can be observed at any time, and the outer surface of the rotating disc 4 is provided with anti-slip lines, so that the rotating disc 4 can be rotated conveniently.

Specifically, as shown in fig. 2, the outer surface of the threaded rod 5 is provided with a vertically arranged limiting sliding groove 8, the limiting sliding groove 8 is connected with the inner wall of the fixing ring 3 through a limiting sliding block, and the threaded rod 5 is limited to rotate so as to move up and down under the action of threads.
