Further, the hanging hook is triangular.

Furthermore, the device also comprises a top cover which is matched with the bottom box for storage.

Compared with the prior art, the utility model the beneficial effect who gains as follows:

1. the utility model discloses simple structure, clamping device are applicable to the pipette of various different specifications. The hanging hook is hung on the S-shaped hook on the hanging beam of the biological safety cabinet, and then the pipette is clamped by the clamping device to be hung in the vertical direction, so that the space can be saved, the three-dimensional space resources of the biological safety cabinet are fully utilized, and the pipette is prevented from being polluted by collision; the bottom box is positioned right below the upper disc through a compression spring and can receive a small amount of liquid left by the pipette;

2. when the device is not needed, the upper disc is stacked and placed in the bottom box by overcoming the elastic force of the compression spring, then the two fixing hooks are fixedly connected to the hanging hook, and the top cover is installed on the bottom box, so that the storage effect is realized, and the storage space of the device in an idle state can be reduced;

3. clamping device is used for the pipette of centre gripping different models, deposits alone when not using usually, and cross contamination is avoided in autoclaving. During the use, handheld clamping device comes to press from both sides tight pipette and then installs on the hanging wall outer circumference, avoids polluting the pipette.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. The described embodiments are only some embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present invention, it should be understood that the terms "left", "right", "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

The utility model provides a suspension type pipet stand for biological safety cabinet, as shown in figures 1-3, which is mainly

Comprises a bottom case 1, an upper disc 3, a compression spring 2, a top cover 7 and four clamping devices 5. The upper plate 3 is cylindrical, and a triangular metal suspension hook 4 is arranged at the middle position of the upper part of the upper plate. Clamping device 5 is the elastic clamp, and the centre gripping department of elastic clamp is circular-arc and is equipped with the soft glue film, clamping device 5 is the plastics material, and its afterbody has moulded plastics the connecting rod. Clamping device 5 is used for the pipette of centre gripping different models, deposits alone when not using usually, and cross contamination is avoided in autoclaving. When in use, the hand-held clamping device 5 clamps the pipette and takes the pipette off from the pipette gun, thereby preventing pollution. Four mounting holes are processed on the outer circumferential surface of the upper disc 3, and the connecting rod of the clamping device 5 is inserted into the mounting holes to realize fixation. The bottom box 1 is a cylindrical hollow structure, the bottom box 1 and the upper disc 3 are connected into a whole through the compression spring 2, the bottom box 1 is positioned under the upper disc 3, and the distance between the bottom box 1 and the upper disc 3 is larger than the length of a pipette in a free state of the compression spring 2.
