Problems solved by technology

[0002] At present, the test tube rack is usually composed of a base, a panel and a device for connection and support. The upper panel has a number of cavities, and the test tube can be inserted into it. Both are easy to break when the test tube mouth touches the bottom when inserting and placing the test tube, especially in the occasion of intense and fast cleaning, the fast work is easy to cause excessive force, which will cause damage to the test tube

Embodiment 1

[0013] Such as figure 1 The shown test tube rack for preventing test tubes from being broken includes a base 1 and a fixed column 2 arranged on the base, and is characterized in that the fixed column 2 is two sections nested with each other, and the nested surfaces are rough surfaces , increase the friction, so that the upper half is not easy to slide down. When inserting test tubes of different lengths, the length of the fixed column 2 can be adjusted to make it longer than the test tube length. At this time, when the test tubes are inserted, the test tubes will not be bumped into the base 1, thereby avoiding damage.

Embodiment 2

[0015] Such as figure 1 The shown test tube rack for preventing test tubes from being broken includes a base 1 and a fixed column 2 arranged on the base, and is characterized in that the fixed column 2 is two sections nested with each other, and the nested surfaces are rough surfaces , increase the friction, so that the upper half is not easy to slide down. When inserting test tubes of different lengths, the length of the fixed column 2 can be adjusted to make it longer than the test tube length. At this time, when the test tubes are inserted, the test tubes will not be bumped into the base 1, thereby avoiding damage. The upper end of the fixed column 2 is provided with a sponge part 3, which relieves the force of the sleeve, and even if it is inserted quickly, the bottom of the test tube will not be damaged due to impact.

Embodiment 3

[0017] Such as figure 1 The shown test tube rack for preventing test tubes from being broken includes a base 1 and a fixed column 2 arranged on the base, and is characterized in that the fixed column 2 is two sections nested with each other, and the nested surfaces are rough surfaces , increase the friction, so that the upper half is not easy to slide down. When inserting test tubes of different lengths, the length of the fixed column 2 can be adjusted to make it longer than the test tube length. At this time, when the test tubes are inserted, the test tubes will not be bumped into the base 1, thereby avoiding damage. The upper end of the fixed column 2 is provided with a sponge part 3, which relieves the force of the sleeve, and even if it is inserted quickly, the bottom of the test tube will not be damaged due to impact. The sponge part 3 is hemispherical, which fits better with the bottom of the test tube, and prevents moisture deposition at the bottom of the test tube cau...

Abstract

The invention discloses a test tube rack for preventing the striking of a test tube. The test tube rack comprises a base and a fixing column arranged on the base and is characterized in that the fixing column consists of two sections which are sleeved with each other, wherein the sleeved surfaces are rough surfaces, so that the friction force is increased and the upper half section cannot slide off easily. When test tubes with different lengths are inserted, the length of the fixing column can be adjusted, and the fixing column is longer than the test tubes, at the moment, when the test tubes are inserted, the test tubes cannot strike the base so as to be prevented from being damaged. According to the test tube rack, the length of the fixing column can be adjusted, so that openings of the test tubes cannot contact the bottom, so that the test tubes are protected.

Description

technical field [0001] The invention relates to an experimental device, in particular to a test tube rack for preventing test tubes from being broken. Background technique [0002] At present, the test tube rack is usually composed of a base, a panel, and a device for connection and support. The upper panel has a number of cavities, and the test tube can be inserted into it. Both are easy to break when the test tube mouth touches the bottom when inserting and placing the test tube, especially in the occasion of intense and fast cleaning, the fast work is easy to cause excessive force, which will cause damage to the test tube. Contents of the invention [0003] In order to overcome the deficiencies of the existing test tube rack, the present invention designs a test tube rack to prevent the test tube from being broken, and the length of the fixed column can be adjusted, so that the test tube mouth cannot touch the bottom and protect the test tube. [0004] In order to solv...
