Description

Technical Field

[0001] This utility model relates to the field of liquid mixing equipment technology, specifically to a spherical vibration damping pad and a mixing device. Background Technology

[0002] A mixer is a commonly used liquid mixing device in the biological or medical fields. It is used to replace manual labor to achieve thorough and uniform mixing of two or more liquids or soluble solid samples. It is mainly used in fields with high requirements for sample and reagent mixing.

[0003] Existing mixers typically use rigid feet or simple spring feet, which offer unsatisfactory vibration damping, generate significant noise, and cause the instrument to shift on the table due to vibrations, affecting its safe operation. Therefore, we propose a spherical vibration-damping foot and a corresponding mixer. Utility Model Content

[0004] This application provides a spherical vibration damping pad and a mixer to at least solve the problems in the prior art where the pads of the mixer are generally hard pads or simple spring pads, which have unsatisfactory vibration damping effect, high noise, and the vibration of the instrument during operation can also cause the instrument to shift on the table, affecting the safe use of the instrument.

[0005] In a first aspect, this application provides a spherical vibration-damping foot pad, including a ball assembly, the lower end of which has a ball compartment, and further comprising:

[0006] A rubber ball has a horizontally oriented through cavity that can elastically deform under stress in its middle part, and at least one flat part is formed on the outer surface of the rubber ball. The upper part of the rubber ball is assembled in the ball chamber part, and the flat part is located at the bottom end of the rubber ball to increase the support contact area.

[0007] Optionally, the upper end of the ball assembly has an integrally formed chassis portion with a minimum radius greater than the maximum radius of the ball compartment portion.

[0008] Optionally, there are two planar portions, located at the top and bottom ends of the assembled planar portions.

[0009] Optionally, a first screw hole is provided in the ball chamber, and a second screw hole is provided at the top of the rubber ball that is not connected to the through cavity. The rubber ball is fixed in the ball chamber by connecting the first screw hole and the second screw hole with countersunk screws.

[0010] Secondly, this application provides a mixer, which includes a housing component, and a plurality of spherical vibration damping pads as described in the first aspect are installed at the bottom end of the housing component.

[0011] Compared with related technologies, the spherical vibration damping pad and mixing device provided in this application have at least the following technical advantages:

[0012] The rubber material of the rubber ball component provides the first layer of vibration reduction during the operation of the mixer. The internal through-cavity deforms elastically during vibration, providing a second layer of vibration reduction. Furthermore, the flat part increases the support contact area, and the flexible contact friction between the rubber ball component and the table surface is relatively large. In this way, the stable support effect is optimized, and vibration displacement during the operation of the mixer is avoided.

[0025] Example 1

[0026] This utility model embodiment provides a spherical vibration damping foot pad. Figure 1 This is a schematic diagram of a mixer structure according to an exemplary embodiment. Figure 1 . Figure 2 yes Figure 1 Enlarged schematic diagram of structure A in the middle. Figure 3 This is an exploded view of a spherical vibration damping foot pad structure according to an exemplary embodiment. Figure 1-3 As shown, the spherical vibration damping pad includes a ball assembly 301, the lower end of which has a ball compartment 303, and...

[0027] A rubber ball 305 has a horizontally oriented through cavity 307 for elastic deformation under stress in its middle part, and at least one flat part 306 is formed on the outer surface of the rubber ball 305. The upper part of the rubber ball 305 is assembled in the ball chamber part 303, and the flat part 306 is located at the bottom end of the rubber ball 305 to increase the support contact area.

[0028] In the technical solutions of the above embodiments, please refer to the appendix. Figure 2The ball assembly 301 is installed at the bottom of the instrument, and the upper part of the rubber ball 305 is assembled in the ball chamber 303. When the lower end of the rubber ball 305 contacts the table or the ground, the vibration of the instrument is transmitted to the rubber ball 305. The rubber material plays a first-level vibration damping role. The through cavity 307 inside it deforms elastically during vibration, playing a second-level vibration damping role. In addition, the combined flat part 306 increases the support contact area and the rubber ball 305 has a large flexible contact friction with the table, which plays a stable support role and avoids vibration displacement during instrument operation.

[0029] In this embodiment, refer to the appendix. Figure 3 The upper end of the ball assembly 301 is integrally formed with a chassis part 302 whose minimum radius is larger than the maximum radius of the ball compartment part 303. The chassis part 302 has assembly holes, which facilitates the installation of the spherical vibration damping pads to the bottom of the instrument by means of the first screw 309, and increases the contact area between the spherical vibration damping pads and the bottom of the equipment, so as to better bear the vibration of the instrument and improve the vibration damping effect.

[0030] In this embodiment, refer to the appendix. Figure 2-3 The number of the planar portions 306 is two, located at the top and bottom ends of the assembled planar portions 306 respectively; a first screw hole 304 is provided in the ball chamber portion 303, and a second screw hole 308 is provided at the top of the rubber ball 305, which is not connected to the through cavity 307; the rubber ball 305 is fixed in the ball chamber portion 303 by connecting the first screw hole 304 and the second screw hole 308 with countersunk screws.

[0031] In the technical solutions of the above embodiments, refer to the appendix. Figure 3 There are two flat parts 306, and each flat part 306 has a second screw hole 308 in the middle, which facilitates quick assembly and eliminates the need to distinguish between the front and back.

[0032] In summary, the spherical vibration damping pad provided in this embodiment of the present invention achieves a first-level vibration damping effect through the rubber material of the rubber ball 305, and a second-level vibration damping effect through the elastic deformation of the internal through cavity 307 during vibration. At the same time, the deformation damping effect of the spherical structure under force is also better than other shapes. Furthermore, the combination of the flat part 306 increases the support contact area and the flexible contact friction between the rubber ball 305 and the table surface is relatively large. In this way, the stable support effect is optimized, and vibration displacement during instrument operation is avoided.

[0033] Example 2

[0034] Embodiment 2 of this utility model provides a mixer. Figure 4 This is a schematic diagram of a mixer structure according to an exemplary embodiment. Figure 2 .like Figure 1-4As shown, the mixer includes a housing 10, and a plurality of spherical vibration damping pads as described in the first aspect are installed at the bottom end of the housing 10.

[0035] Other undescribed structures are described in Example 1.

[0036] In summary, the spherical vibration damping pad and mixer provided in this embodiment of the present invention achieve a first-level vibration damping effect through the rubber material of the rubber ball 305, and the elastic deformation of the internal through cavity 307 during vibration provides a second-level vibration damping effect. Furthermore, the combination of the flat part 306 increases the support contact area, and the flexible contact friction between the rubber ball 305 and the table surface is relatively large. In this way, the stable support effect is optimized, and vibration displacement during the operation of the mixer is avoided.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
