Description

Spherical vibration reduction foot pad and mixing instrument Technical Field The utility model relates to the technical field of liquid mixing equipment, in particular to a spherical vibration reduction foot pad and a mixing instrument. Background The mixing instrument is a liquid mixing device commonly used in the biological or medical field, is used for replacing manual work to fully and uniformly mix more than two kinds of liquid or soluble solid samples, and is mainly applied to the field with higher requirements on mixing samples and reagents. The foot pad of the existing mixing instrument is generally a hard foot pad or a simple spring foot pad, the vibration reduction effect is not ideal, the noise is large, and the vibration of the instrument work can also cause the instrument to displace on the table top, so that the safe use of the instrument is affected. Therefore, we propose a spherical vibration damping foot pad and a mixing instrument. Disclosure of utility model The application provides a spherical vibration reduction foot pad and a mixing instrument, which at least solve the problems that the foot pad of the mixing instrument in the prior art is generally a hard foot pad or a simple spring foot pad, the vibration reduction effect is not ideal, the noise is high, the instrument can be displaced on a table top due to vibration of the working of the instrument, and the safe use of the instrument is affected. In a first aspect, the present application provides a spherical vibration damping foot pad, including a ball sleeve, wherein a ball bin is provided at the lower end of the ball sleeve, and the spherical vibration damping foot pad further includes: The rubber ball piece, the middle part level is offered the atress elastic deformation's chamber that runs through, just the surface shaping of rubber ball piece has at least one plane portion, rubber ball piece upper portion assemble in the ball storehouse portion, just plane portion is located the bottom of rubber ball piece is in order to increase and supports area of contact. Optionally, the upper end of the ball sleeve member is integrally formed with a chassis portion having a minimum radius greater than a maximum radius of the ball compartment portion. Optionally, the number of the planar parts is two, and the planar parts are respectively positioned at the top and bottom ends of the assembled planar parts. Optionally, a first screw hole is formed in the ball bin part, a second screw hole which is not communicated with the penetrating cavity is formed in the top end of the rubber ball piece, and the rubber ball piece is connected with the first screw hole and the second screw hole through countersunk screws so as to be fixed in the ball bin part. In a second aspect, the application provides a mixing instrument, which comprises a shell, wherein the bottom end of the shell is provided with a plurality of spherical vibration damping foot pads according to the first aspect. Compared with the related art, the spherical vibration reduction foot pad and the mixing instrument provided by the application have at least the following technical effects: The rubber material through the rubber ball spare plays mixing appearance operational vibration's first heavy damping effect, and its inside runs through the chamber elastic deformation when the vibration, plays the heavy damping effect of second, and combines plane portion increase support area of contact and rubber ball spare and mesa's flexible contact frictional force great to this mode, optimize stable supporting effect, avoid the vibration displacement under the mixing appearance operating condition.
