Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1: A test tube shaker, such as Figure 1 and Figure 2As shown, the device includes an oscillator body 1, a vibration platform 2 on top of the oscillator body 1, a mounting head 3 fixedly mounted on top of the vibration platform 2, a first mounting plate fixedly mounted on top of the mounting head 3, and a vertically arranged lifting adjustment rod 4 fixedly mounted on top of the first mounting plate. The length of the lifting adjustment rod 4 in the vertical direction is adjustable. Specifically, the lifting adjustment rod 4 includes a first fixed tube 401 and a first movable rod 402. The lower end of the first fixed tube 401 is fixedly mounted on the first mounting plate, and the lower end of the first movable rod 402 is movably inserted into the first fixed tube 401. The first fixed tube 401 has a through first screw hole on its side wall, and the first movable rod 402 has several second screw holes spaced vertically. When the first movable rod 402 moves up and down, any one of the second screw holes can correspond to the inner and outer of the first screw hole. A positioning bolt 403 passes through the inner and outer corresponding first and second screw holes.
[0028] A second mounting plate 404 is fixedly mounted on the top of the first movable rod 402, and a vertically mounted mounting shaft is fixedly mounted on the top of the second mounting plate 404. A horizontally mounted test tube clamp is fixedly fitted onto the mounting shaft, and the test tube clamp is used to clamp and fix the test tube 13.
[0029] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the mounting shaft includes a second fixed tube 5 and a second movable rod 6. The second fixed tube 5 is an internally threaded sleeve structure that is open at both ends, and the lower end of the second fixed tube 5 is fixed to the top of the lifting adjustment rod 4.
[0030] The lower end of the second movable rod 6 is provided with a first threaded rod head 601, which is inserted into the second fixed tube 5 and threadedly connected to it.
[0031] The test tube clamp includes a first test tube clamp 7 and a second test tube clamp 8 arranged at intervals. The first test tube clamp 7 has a first through hole 701 at its center. The first test tube clamp 7 is fixedly mounted on the second fixed tube 5 through the first through hole 701. The first test tube clamp 7 has a number of mounting holes 702 arranged radially thereon. The mounting holes 702 are used for the lower end of the test tube 13 to pass through.
[0032] The second test tube chuck 8 has a second through hole 801 at its center. The second test tube chuck 8 is fixedly mounted on the second movable rod 6 through the second through hole 801. The second test tube chuck 8 has several adjustment slots 802 that correspond to the mounting holes 702. The adjustment slots 802 are arc-shaped. The arc extension direction of the adjustment slots 802 is concentric with that of the second test tube chuck 8. The width of the adjustment slots 802 is equal to the inner diameter of the mounting holes 702, and the length of the adjustment slots 802 is greater than the inner diameter of the mounting holes 702.
[0033] The mounting shaft is fitted with a pressure strip component that can be adjusted up and down and rotated. The pressure strip component is used to press against the top of the test tube 13, and after rotation, the pressure strip component can be misaligned with the test tube 13 in the horizontal plane. The mounting shaft is fitted with a limiting component for adjusting the up and down position of the pressure strip component.
[0034] Specifically, such as Figure 2 and Figure 5 As shown, the pressure strip component includes a ring plate 9 and several pressure strips 10 fixedly disposed around the periphery of the ring plate 9. The pressure strips 10 extend radially along the second test tube chuck 8. When the ring plate 9 rotates, the pressure strips 10 can press against the adjustment slots 802 in the same radial direction or form a misalignment with the adjustment slots 802 in the same radial direction. A rubber pad layer 1001 is fixedly disposed at the bottom of the pressure strips 10.
[0035] The upper end of the second movable rod 6 is fixedly provided with a second threaded rod head 602, and the ring plate 9 is movably fitted onto the second threaded rod head 602.
[0036] The limiting component includes a threaded sleeve 11 that is fitted onto and threadedly connected to the second threaded rod head 602, and the threaded sleeve 11 is located above the ring plate 9. A T-shaped handle 12 is fixedly provided on the top of the second threaded rod head 602.
[0037] Working principle: When using, first adjust the length of the lifting adjustment rod 4 according to the length of the test tube 13 to avoid the bottom of the test tube 13 from contacting the upper surface of the test tube shaker.
[0038] Then, by rotating the second movable rod 6 through the handle 12, the second test tube chuck 8 is rotated, so that the adjustment slot 802 on the second test tube chuck 8 corresponds vertically to the mounting hole 702 on the first test tube chuck 7. Then, the lower end of the test tube 13 passes through the adjustment slot 802 and the mounting hole 702 from top to bottom, so that the edge of the top of the test tube 13 overlaps the upper surface of the second test tube chuck 8.
[0039] By rotating the second movable rod 6 with the handle 12, the second test tube chuck 8 is rotated until one end of the adjusting slot 802 is pressed against the side wall of the test tube 13, thereby quickly clamping and fixing all the test tubes 13.
[0040] Then, move the pressure bar 10 and the ring plate 9 so that the pressure bar 10 presses against the top of the test tube 13. Then rotate the threaded sleeve 11 to push the ring plate 9 downward, which in turn moves the pressure bar 10 downward, so that the upper end of the test tube 13 abuts against the bottom of the rubber pad 1001 at the bottom of the pressure bar 10 and is sealed by the rubber pad 1001 to prevent the test tube 13 from moving during vibration, and also to prevent the liquid in the test tube 13 from accidentally spilling out during vibration.
[0041] After oscillation is complete, reverse the above steps to reset, and then remove test tube 13.
[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
