Description

Technical Field

[0001] The utility model relates to the technical field of test tube cleaning, in particular to a laboratory test tube cleaning device. Background Art

[0002] In the laboratory, test tubes for experiments need to be cleaned to ensure the cleanliness of the test tubes before the next experiment and reduce experimental errors. Existing laboratory test tube cleaning is mostly done by manually inserting a test tube brush into the inside of the test tube, and continuously rotating the test tube brush to make it contact with the inner wall of the test tube to achieve cleaning. However, this cleaning method is extremely inefficient, and foreign matter is easily retained on the inner wall of the test tube, making it difficult to clean. Although some existing test tube automatic cleaning devices can improve the cleaning efficiency, they cannot effectively clamp test tubes of different diameters. Once the clamping force is insufficient, the cleaning effect is poor. If the clamping force is too large, the test tube is easily broken. Therefore, a laboratory test tube cleaning device is proposed to solve the above problems. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a laboratory test tube cleaning device, which solves the technical problems of poor cleaning effect and easy damage of the test tubes due to different clamping forces during the cleaning process of test tubes with different diameters.

[0005] The adaptive clamping mechanism includes a mounting groove opened on the top wall of the body base, four longitudinal limit rods are symmetrically arranged on the outside of the mounting groove, four arc-shaped clamping arms are slidably installed inside the mounting groove, the outer side wall of the arc-shaped clamping arm is fixedly connected with a spring, the other end of the spring is fixedly connected with an electromagnet, the top of the electromagnet is fixedly connected with an elastic airbag, and the top of the elastic airbag is fixedly connected with a magnetic wedge block.

[0006] Preferably, the arc-shaped clamping arm is made of a magnetic material, and the magnetism of the arc-shaped clamping arm is consistent with the magnetism of the electromagnet;

[0007] The four arc-shaped clamping arms are arranged equidistantly along the circumference of the mounting groove, and the inner side walls of the arc-shaped clamping arms are arranged as 90° arc-shaped surfaces;

[0008] The magnetic wedge block is slidably mounted inside the base of the machine body along the longitudinal direction, and the side wall of the magnetic wedge block is fixedly connected to the side wall of the longitudinal limiting rod;

[0009] The electromagnet is arranged in an inverted L shape, and the magnetism of the magnetic wedge block is consistent with the magnetism of the electromagnet.

[0010] Preferably, a micro motor is fixedly connected to the bottom wall output end of the electric push rod, and the cleaning brush is fixedly connected to the bottom wall of the micro motor.

[0011] By means of the above technical solution, the utility model provides a laboratory test tube cleaning device, which has at least the following beneficial effects:

[0012] 1. The utility model realizes the clamping of test tubes of different diameters through an adaptive clamping mechanism, and realizes the adaptability clamping of the bottom walls of test tubes of different diameters through the coordinated setting of the electromagnet, the spring and the arc-shaped clamping arm, which greatly reduces the shaking of the test tubes during cleaning, avoids the test tubes from being broken due to excessive clamping force, and effectively improves the cleaning efficiency of the test tubes.

[0013] 2. The utility model realizes the clamping of the bottom wall of the test tube and the longitudinal limitation of the side wall by driving the magnetic wedge block and the arc-shaped clamping arm to slide synchronously by the electromagnet, and utilizes the magnetic suction force to limit the test tube during cleaning, thereby further improving the stability of the test tube during cleaning.

A magnetic wedge block 46 is fixedly connected to the top of the elastic airbag 45. After the electromagnet 44 is turned on, the spring 43 and the elastic airbag 45 are compressed synchronously under the action of the electromagnetic repulsive force, so that the longitudinal limit rod 41 moves upward, and the arc-shaped clamping arms 42 approach each other, thereby clamping the bottom wall and side walls of the test tube. The test tubes of different diameters are clamped by the adaptive clamping mechanism 4. At the same time, the electromagnet 44, the spring 43 and the arc-shaped clamping arms 42 are matched to achieve adaptability to the bottom walls of test tubes of different diameters.
