Detailed Description

In order to make the technical means, the original characteristics, the achieved purpose and the efficacy of the utility model easy to understand, the utility model is further described with reference to the specific drawings.

As shown in fig. 1-4, an automatic capping device for centrifuge tubes with a lid comprises a base 9 and a first cylinder 1, wherein a slide rail 8 is fixedly connected to the top of the base 9, the slide rail 8 is slidably connected to a mounting plate 4 through a slider 7, one end of the mounting plate 4 is hinged to a second cylinder 3, a limiting block 6 is fixedly connected to the other end of the mounting plate, a limiting groove 61 is formed in the limiting block 6, the limiting groove 61 is of a shape like the Chinese character 'li', a gland component is arranged at the end of a piston rod of the second cylinder 3, and the gland component slides along the shape of the limiting groove 61 on the limiting block 6.

In order to match centrifugal tubes of different sizes and covers of different sizes, the first cylinder 1 is used for driving the mounting plate 4 to move on the base 9, and the distance between the limiting block 6 and the positioning tool 12 is adjusted in real time, so that the centrifugal tubes and the covers are located in the working range of the device.

The gland subassembly includes U type piece 10, spacing round 5 and gland wheel 11, and spacing round 5 and gland wheel 11 rotate with U type piece 10 through a bolt jointly and are connected, and spacing round 5 is located the outside of U type piece 10, and gland wheel 11 is located the inboard of U type piece 10.
