Description
Technical Field
The present invention relates to a laboratory instrument, and more particularly, it relates to a self-adjusting cuvette cartridge.
Background
The test tube is a common laboratory vessel in the biochemical field, and multiple sampling and sample preparation are often required to be loaded into the test tube during experiments, and a large number of test tubes are usually required to be placed and stored by using a test tube box under the condition. However, the test tube specification that uses is more in daily work, and the test tube box of depositing the test tube also has different sizes for this reason to match corresponding test tube, otherwise either the test tube can't put into the test tube box, or put into the back too loose spaciously, the test tube acutely rocks, collides, the sample splashes when leading to the test tube box to move. The existing test tube box has fixed hole site size and can not adapt to test tubes of various specifications simultaneously, so that a user must prepare test tube boxes of various specifications, and even test tubes of different specifications with lower use frequency at ordinary times have to be provided with corresponding test tube boxes, so that the experimental equipment has multiple types, low overall utilization rate, poor universality and inconvenient management. Utility model with publication number CN208591874U specially does benefit to 2019 and discloses a test tube box for inspection administrative or technical offices in 3 month 12, comprises a box bod, there is the lid at the top of box body through hinge swing joint, the inside of box body is provided with the backup pad, and the both sides of backup pad respectively with the both sides fixed connection of box inner chamber, the equal fixedly connected with fixed plate in both sides at backup pad top, the equal first spring of fixedly connected with in one side that two fixed plates are relative, logical groove has been seted up on the surface of fixed plate. The utility model discloses a set up the fixed plate, first spring, lead to the groove, the connecting rod, the arc clamp splice, first slider, the cooperation of first spout and arm-tie is used, the current poor problem of test tube box fixed effect for the inspection administrative or technical offices has been solved, this test tube box for the inspection administrative or technical offices possesses fixed effectual advantage, at the in-process that uses, the unrestrained phenomenon of slope is difficult to appear in the liquid that waits to detect, the degree of accuracy of testing result has been improved, the medical personnel's of being convenient for use, be worth using widely. However, the technical problem to be solved by the utility model is not to improve the universality of the test tube box.
Disclosure of Invention
The existing test tube boxes are various in types, low in overall utilization rate, poor in universality and inconvenient to manage, and in order to overcome the defects, the invention provides the self-adjusting test tube box which can automatically adjust the clamping force according to the specification of the test tube and ensure that test tubes of different specifications can be suitable for use.
The technical scheme of the invention is as follows: the utility model provides a self-adjusting test tube box, includes the test tube box body, is equipped with the test tube frame plate on the test tube box body, is equipped with the test tube jack that arranges into ranks on the test tube frame plate, still is equipped with on the test tube box body and touches pressure formula test tube fixture, but self-adjusting test tube fixture is including the global test tube clamping part of centre gripping test tube, be located test tube jack below and can drive the test tube clamping part touch the drive division, connect the test tube clamping part and touch the connecting portion and the centre gripping controlling means who presses the drive division. When using this self-adjusting test tube box, insert the test tube in the test tube jack, push down hard, touch the drive division and receive and touch the back, through connecting portion drive test tube clamping part, press from both sides the test tube tightly, and the centre gripping controlling means then can keep or relieve the centre gripping of test tube clamping part to the test tube. Because of the contact pressure type test tube clamping mechanism, the self-adjusting test tube box is not used for keeping the posture of a test tube through the edge constraint of a test tube jack like a common test tube box, but is used for providing corresponding clamping force according to the tube diameter of the test tube, so that the self-adjusting test tube box is suitable for test tubes with different specifications, has good universality, can reduce the holding types of the test tube box, reduces the idleness rate of equipment, and is convenient to manage.
