A drawer guide buffer mechanism

Abstract

The present invention provides a drawer guiding buffer mechanism, which includes a buffer mechanism and a chute; wherein, the buffer mechanism includes a buffer frame, a buffer rod, at least one sliding component, at least one elastic component, and a roller; the buffer frame includes a concave cavity and a frame; The buffer rod is located in the cavity, and there are at least two buffer rod through holes, one end of which has a bump, and rollers are installed on the end surface of the bump; the sliding parts are located in the cavity and pass through a buffer rod through hole respectively, and are fixed on the frame; The elastic part is sleeved on the outer surface of the sliding part outside the through hole of the buffer rod, and abuts against the outer surface of the buffer rod and the inner wall of the concave cavity; the inner surface of the roller chute matches and can slide in the chute. The drawer guide buffer mechanism provided by the embodiment of the present invention has a simple structure and low cost, can not only position and guide, but also prevent strength failure and reduce noise generated during operation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drawer guiding buffer mechanism. Background technique [0002] The automatic microbial culture instrument is a microbiological inspection instrument used to test the presence or absence of bacteria in body fluids (mainly blood). The sample bottles placed in the automatic microbial culture instrument need to be continuously incubated at constant temperature and shaken , in order to ensure better growth and amplification of microorganisms, and increase the accuracy of determining whether there are bacteria. [0003] The automatic microbial culture instrument is a fully automatic drawer type, with one or more boxes, each box contains a drawer, and each drawer is equipped with one or more incubation test seats, and each incubation test seat contains multiple layers Vial wells, each of which can hold one vial. On the one hand, in order to facilitate the taking and placing ...

Problems solved by technology

However, since the parts in the above-mentioned connection mechanism are rigidly connected between surfaces, there are the following disadvantages during its operation: 1) The parts of the connection mechanism adopt a surface-to-surface contact method, which increases the 2) Lubricants need to be rubbed between the parts of the connecting mechanism, which increases the maintenance of the instrument, and the lubricant is easy to stick to dust. After sticking to the dust, the friction of the connecting mechanism will also increase, which is more likely to cause damage to the connecting mechanism. 3) Each time the drawer is pushed and pulled, since the weight of each incubation detection seat is heavy, and the connection between the connection mechanism and the incubation detection seat is rigidly connected, the impact on the connection mechanism is very large, which shortens the life of the connection mechanism. There is even a loud noise when the drawer is pushed and pulled
