Description

Technical Field

[0001] The utility model relates to the technical field of biochemical incubators, in particular to a biochemical incubator for testing and inspection which is convenient for taking and placing samples. Background Art

[0002] The biochemical incubator has a two-way temperature control system of refrigeration and heating, and the function of temperature control. It is an important test equipment for scientific research institutions, colleges and universities, production units or department laboratories in the industries of biology, genetic engineering, medicine, health and epidemic prevention, environmental protection, agriculture, forestry and animal husbandry, etc. It is widely used in low-temperature constant temperature tests, culture tests, environmental tests, etc. In biological culture, most of the cell culture fluids are filled in reagent tubes, and due to the structure, most of the reagent tubes are placed on reagent tube racks, and their protective effect is general. Traditional incubators are not convenient for the storage and sampling of reagent tubes, and the test tubes are prone to leakage of the internal culture fluid due to collision and tilt when they are taken out.

[0003] Chinese patent CN218465839U discloses a biochemical incubator that is convenient for taking and placing samples, including a box body and a box cover, which are rotatably connected to each other through a hinge shaft. A test tube storage mechanism is installed inside the box body, and the test tube storage mechanism includes a rotating shaft, a sleeve, a test tube storage disk, an outer protective sleeve disk, storage slot holes and a fixed cross bar. The top surface and the inner bottom surface of the box body are both provided with slide grooves, the side of the box body is provided with waist-shaped holes, the test tube storage disk is installed inside the outer protective sleeve disk, and a fan-shaped notch is provided on the test tube storage disk. The utility model can displace the test tube storage mechanism laterally in the box body, and cooperate with a small drive motor to conveniently place the test tube filled with cell culture fluid in the storage slot hole of the test tube storage mechanism; an outer protective sleeve disk is fixed outside the test tube storage disk, and cooperates with the fan-shaped notch on the test tube storage disk to facilitate the storage and access of reagent tubes, and can also effectively shield and protect the reagent tubes. The whole device is simple and practical, while the biochemical incubator is mainly used for temperature regulation. The device adopts more shielding structures, and there is a temperature difference between the exposed test tube and the internal test tube, which affects the detection result.

[0004] Therefore, those skilled in the art provide a biochemical incubator for testing and inspection that is convenient for taking and placing samples, so as to solve the problems raised in the above background technology. Utility Model Content
