Description

TECHNICAL FIELD

[0001] The utility model relates to test -tube rack technical field especially, it is a test -tube rack with locking function. BACKGROUND

[0002] In the hospital's clinical laboratory, laboratory and all kinds of medical research institutions, test -tube rack as the basic tool of storage and transfer test tube, plays a vital role. Test -tube rack not only needs to ensure the safe storage of test tube, also needs to facilitate medical staff to use. The traditional test -tube rack, usually by durable material such as stainless steel or medical grade plastic is made, design uses the arrangement of fixed aperture, aims at accommodating standard size test tube. The test tube of various sizes in the hospital environment is handled, from small blood collection test tube to larger culture test tube, not one but many. The fixed aperture design of existing test -tube rack when facing non-standard or smaller size test tube, exposes obvious deficiency. Specifically, when smaller size test tube is placed in the test -tube rack with larger aperture, test tube lacks necessary support, and is easy to shake even to dump. This instability not only increases the risk of test tube breakage and sample contamination, but also can lead to the loss of valuable biological samples or inaccurate detection results, directly affects medical diagnosis.

A guide groove is arranged below the test -tube rack, the guide groove is coaxially aligned with the fixed mouth, a pipe wall clamping mechanism is arranged on both sides of the guide groove, the pipe wall clamping mechanism is composed of a fixed sheet and a plurality of elastic sheets, when the test tube is inserted in the guide groove, the elastic sheets on both sides of the test tube abut against the side wall of the test tube, and the opposite clamping force is applied to both sides of the test tube wall, so as to realize the stability of the test tube after placement, avoid the test tube from rotating in the test tube placement chamber, and improve the test efficiency.

[0004] In the above patent, the elastic sheets on both sides of the test tube abut against the side wall of the test tube, and the opposite clamping force is applied to both sides of the test tube wall, so as to realize the stability of the test tube after placement. The elastic sheet structure and elastic force in the clamping structure are different between the elastic sheets on both sides and the test tube when aiming at test tubes of different sizes, which affects the stability of the test tube due to insufficient clamping force for smaller size test tubes, and the problem of easy breakage of test tubes due to excessive clamping force for larger size test tubes.
