Sampling tube rack

Abstract

A sampling tube holder includes a sampling tube support, a sampling tube positioning seat, and a sampling tube fixing pad. The sampling tube positioning seat is disposed on the sampling tube support and has a plurality of first through holes and a plurality of circumferential protrusions extending upward from the periphery of the plurality of first through holes. When a plurality of sampling tubes are inserted through the plurality of first through holes and placed on the sampling tube holder, the lower edges of the plurality of tube caps of the plurality of sampling tubes abut against the top surfaces of the plurality of circumferential protrusions. The sampling tube fixing pad is disposed between the sampling tube positioning seat and the sampling tube support and has a plurality of second through holes corresponding to the plurality of first through holes, wherein the diameter of each second through hole is smaller than the diameter of each first through hole, and a plurality of interference elements are provided around the periphery of each second through hole to accommodate a plurality of sampling tubes of different diameters.

Claims

1. A sampling tube holder, configured to hold a plurality of sampling tubes, the sampling tube holder comprising: a sampling tube support; a sampling tube positioning seat disposed on the sampling tube support, having a plurality of first through holes and a plurality of circumferential protrusions extending upward from the periphery of the plurality of first through holes, wherein when the plurality of sampling tubes are inserted through the plurality of first through holes and placed on the sampling tube holder, the lower edges of the plurality of tube caps of the plurality of sampling tubes abut against the top surface of the plurality of circumferential protrusions; and a sampling tube fixing pad disposed between the sampling tube positioning seat and the sampling tube support, having a plurality of second through holes corresponding to the plurality of first through holes, wherein the diameter of each second through hole is smaller than the diameter of each first through hole, wherein a plurality of interference elements are provided around the periphery of each second through hole to accommodate the plurality of sampling tubes of different diameters.

2. The sampling tube holder as claimed in claim 1, wherein the diameter of each of the first perforations is slightly larger than the diameter of one of the tube bodies of each of the sampling tubes and smaller than the diameter of the tube cap of each of the sampling tubes.

3. The sampling tube holder as claimed in claim 1, wherein the inner wall surfaces of the plurality of surrounding protrusions disposed around the periphery of each of the first perforations are arc-shaped, and their cross-sections collectively define a circle with the same diameter as the first perforation.

4. The sampling tube holder as claimed in claim 1, wherein the sampling tube support is made of a plastic material.

5. The sampling tube rack as claimed in claim 1, wherein a gap is defined between two adjacent interference elements, the gap extending radially from the periphery of the second perforation to the periphery of the first perforation.

6. The sampling tube holder as claimed in claim 1, wherein the sampling tube fixing pad is made of a soft, elastic material.

7. The sampling tube support as claimed in claim 1, wherein the sampling tube support includes a top frame, a bottom frame, and a plurality of positioning supports for connecting and fixing the top frame and the bottom frame.

8. The sampling tube rack as claimed in claim 7, wherein the top frame, the bottom frame, and the plurality of positioning supports are made of a metal material or an engineering plastic.

9. The sampling tube holder as claimed in claim 7, wherein the sampling tube support further includes a sampling tube limiting plate disposed between the top frame and the bottom frame, and connected and fixed together with the top frame and the bottom frame through the plurality of positioning pillars.

10. The sampling tube holder as claimed in claim 9, wherein the sampling tube limiting plate has a plurality of third perforations corresponding to the plurality of first perforations and the plurality of second perforations.

11. The sampling tube holder as claimed in claim 10, wherein the diameter of each of the third perforations is substantially the same as the diameter of each of the first perforations, allowing the sampling tube to be inserted therein and preventing the sampling tube from being skewed.

12. The sampling tube holder as claimed in claim 9, wherein the sampling tube limiting plate is made of a plastic material.

13. The sampling tube holder as claimed in claim 7, wherein the top frame is provided with a plurality of positioning protrusions, and the sampling tube positioning seat and the sampling tube fixing pad are respectively provided with a plurality of first positioning holes and a plurality of second positioning holes corresponding to the plurality of positioning protrusions, and the sampling tube fixing pad and the sampling tube positioning seat can be positioned on the sampling tube support by fitting the plurality of second positioning holes and the plurality of first positioning holes onto the plurality of positioning protrusions.

14. A sampling tube holder, configured to hold a sampling tube, the sampling tube holder comprising: a sampling tube support; a sampling tube positioning seat disposed on the sampling tube support, having a first through hole and a plurality of circumferential protrusions extending upward from the periphery of the first through hole, wherein when the sampling tube is inserted through the first through hole and placed on the sampling tube holder, the lower edge of a cap of the sampling tube abuts against the top surface of the plurality of circumferential protrusions; and a sampling tube fixing pad disposed between the sampling tube positioning seat and the sampling tube support, having a second through hole corresponding to the first through hole, wherein the diameter of the second through hole is smaller than the diameter of the first through hole, wherein a plurality of interference elements are provided around the second through hole to accommodate sampling tubes of different diameters.
