[0044] Research has found that in the related technology, after the test tube 3 is placed on the bracket body 1, when the bracket body 1 starts to vibrate to drive the test tube 3 to oscillate, the bottom of the test tube 3 is likely to collide with the bracket body 1, causing damage to the test tube 3, and the oscillation of the test tube 3 is likely to cause the test tube 3 to fall off the bracket body 1.

[0045] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0046] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0047] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0048] like Figure 1 As shown, at least one disclosed embodiment provides a test tube stand for chemical experiments with an oscillation function, comprising: a stand body 1, on which are arranged a plurality of pairs of support blocks 11, with a gap between two support blocks 11, so as to form a plurality of placement stations adapted to the size of the test tube 3 between the two support blocks 11, and each placement station can correspondingly place a test tube 3; a clamping mechanism 2 is provided at the bottom of the support block 11, and the clamping mechanism 2 is suitable for clamping the test tube 3 near the bottom after the test tube 3 is placed in the placement station; a vibration mechanism is provided on the stand body 1 to vibrate the stand body 1; and when the test tube 3 is placed on the stand body 1, the bottom of the test tube 3 is clamped to avoid collision between the bottom of the test tube 3 and the stand body 1 when the test tube 3 is oscillated, thereby avoiding damage to the test tube 3.

[0049] The vibration mechanism may be a plurality of vibration motors, the number of which may be adjusted according to the size of the support body 1 . The vibration motors are used to make the support body 1 vibrate, thereby driving the test tube 3 to oscillate.

[0050] like Figure 2 As shown, in some embodiments, a groove 12 corresponding to the clamping mechanism 2 is provided at the bottom of the support block 11, and the support block 11 is rotatably connected to the inner wall of the groove 12; a clamping mechanism 2 is provided at the bottom of each support block 11 in a pair of support blocks 11, and the relative clamping mechanisms 2 in the two support blocks 11 are suitable for clamping the test tube 3 from two directions; after the test tube 3 is placed, the bottom of the test tube 3 is clamped from two opposite directions by a pair of clamping mechanisms 2, and during the oscillation of the test tube 3, it is ensured that the test tube 3 does not collide with the bracket body 1, thereby avoiding damage to the test tube 3; when the test tube 3 is placed in the placement station from top to bottom, or the clamping mechanism 2 is pressed Figure 2 Rotate in the direction of F.

[0051] like Figure 3 and Figure 4As shown, in some embodiments, the clamping mechanism 2 includes: a rotating plate 21; the rotating plate 21 is rotatably connected to the side wall of the groove 12, and the rotating plate 21 is connected to the side wall of the groove 12 by a torsion spring. For example, a rotating shaft is arranged on both sides of the rotating plate 21, and the rotating shaft is inserted into the side wall of the groove 12, and the rotating shaft is rotatably connected to the groove 12 to facilitate the rotation of the rotating plate 21; the torsion spring can make the rotating plate 21 in a horizontal state without being affected by other external forces; each placement station is provided with a pair of clamping mechanisms 2, and there is a gap between the two rotating plates 21 of the two clamping mechanisms 2, so that when the test tube 3 is placed from top to bottom, it is more convenient for the bottom end of the test tube 3 to press the rotating plate 21 to rotate, and make the bottom end of the test tube 3 pass through between the two rotating plates 21.

[0052] In some embodiments, a notch 22 is provided on the rotating plate 21. When the rotating plate 21 is in a horizontal state, the notch 22 is located on the top surface of the rotating plate 21, and at this time, the notch 22 is located in the groove 12; a pair of guide posts 23 are provided in the notch 22, and the length direction of the guide posts 23 is arranged along the length direction of the rotating plate 21; a movable plate 24 is slidably provided on the guide posts 23; a spring 25 is sleeved on the guide posts 23, one end of the spring 25 is connected to the movable plate 24, and the spring 25 is provided on the movable plate 24. The other end of the spring 25 is connected to the side wall of the notch 22; the guide column 23 can guide and limit the movement of the movable plate 24 to prevent the movable plate 24 from offset during movement; when the rotating plate 21 is in the initial state, that is, the rotating plate 21 is horizontal, the notch 22 is in the groove 12, and the part of the rotating plate 21 without the notch 22 extends out of the groove 12, and the movable plate 24 contacts the inner wall of the groove 12. At this time, the spring 25 is in a compressed state, and the movable plate 24 is closer to the inner top surface of the groove 12 than the bottom surface of the rotating plate 21.

[0053] In some embodiments, the surface of the movable plate 24 that contacts the test tube 3 is arc-shaped, so that the movable plate 24 can better hold the test tube 3 when in contact with the test tube 3.

[0054] In some embodiments, a through hole 26 is provided on the rotating plate 21. When the rotating plate 21 is in a vertical state, one end of the through hole 26 is located on the bottom surface of the rotating plate 21, and the other end of the through hole 26 is connected to the notch 22, and the other end of the through hole 26 is located below the movable plate 24; a plate body 27 is provided on the side of the movable plate 24 close to the through hole 26, and the plate body 27 can extend into the through hole 26, and the size of the plate body 27 is smaller than the size of the through hole 26; the inner top surface of the groove 12 is arc-shaped, and the movable plate 24 will always keep in contact with the inner wall and the inner top surface of the groove 12 through the spring 25 during the rotation of the rotating plate 21, so the arc-shaped inner top surface can facilitate the rotation of the rotating plate 21; the outer wall of the test tube 3 There will be residual liquid on the surface of the test tube 3. When the test tube 3 is placed at the placement station, the residual liquid may flow into the groove 12 along the side wall of the support block 11. After the liquid dries up in the groove 12, the material in the liquid will become powder and adhere to the inner wall of the groove 12. During the rotation of the rotating plate 21, the powder will be scraped off by the moving plate 24, and the scraped powder will fall through the through hole 26 to prevent the scraped powder from accumulating on the rotating plate 21; when the test tube 3 finishes oscillating and moves out of the placement station, the torsion spring drives the rotating plate 21 to rotate horizontally again. At this time, the moving plate 24 or the rotating plate 21 can scrape off the liquid flowing to the inner wall of the groove 12, and at this time, the moving plate 24 moves toward the through hole 26 and the plate 24 body is inserted into the through hole 26 to prevent the through hole 26 from being blocked by powder.

[0055] like Figure 5 As shown, in some embodiments, a rubber ring 31 is provided on the side wall of the test tube 3, and the rubber ring 31 is provided close to the top surface of the test tube 3; at least one pair of hooks 32 are provided on the bottom surface of the rubber ring 31; a slot corresponding to the hook 32 is provided on the top surface of the support block 11, and an extension plate is provided in the middle of the slot to partially cover the top surface opening of the slot through the extension plate; when the test tube 3 is placed in the placement station from top to bottom, the hook 32 will be inserted into the slot, and after the insertion, the inclined part of the hook 32 will be under the extension plate to prevent the test tube 3 from falling off during the oscillation process. After the oscillation is over, the operator can manually deform the rubber ring 31 so that the inclined part of the hook 32 moves to the unblocked part of the slot, so as to facilitate the removal of the test tube 3.

[0056] In some embodiments, a limit ring 33 is provided on the side wall of the test tube 3, and the limit ring 33 is provided near the bottom of the test tube 3; when the rotating plate 21 is in a vertical state, the movable plate 24 is closer to the test tube 3 than the support block 11, and at this time the movable plate 24 is moved upward by the spring 25, so that the movable plate 24 contacts the bottom surface of the limit ring 33; when the rotating plate 21 is rotated to a vertical or nearly vertical state, the movable plate 24 is completely extended from the groove 12, and the top surface in the groove 12 no longer blocks the movable plate 24. At this time, the movable plate 24 is moved upward by the spring 25, and the movable plate 24 contacts the bottom surface of the limit ring 33, and the movable plate 24 lifts the test tube 3 upward, so that the inclined part of the hook 32 contacts the bottom surface of the extension plate, so that the hook 32 can press the extension plate tightly to prevent the hook 32 from being separated from the card slot during the oscillation process, and to prevent the test tube 3 from falling off the bracket body 1.

[0057] The test tube 3 is placed in the placement station from top to bottom manually. During the placement process, the bottom end of the test tube 3 contacts the rotating plate 21, causing the rotating plate 21 to be squeezed and rotated. The movable plate 24 rotates upward, contacts the inner wall of the groove 12, and scrapes off the remaining powder on the inner wall of the groove 12. The scraped powder falls out through the through hole 26. The size of the through hole 26 is larger than the plate body 27 to prevent the plate body 27 from blocking the through hole 26. The test tube 3 will gradually press the horizontal rotating plate 21 to a vertical or nearly vertical state. At this time, the movable plate 24 is completely moved out of the groove 12, and the movable plate 24 contacts the position close to the bottom of the test tube 3 to hold the test tube 3 tightly to prevent the test tube 3 from colliding with the bracket body 1 during the oscillation process. The movable plate 24 that is completely moved out of the groove 12 will move upward due to the reset of the spring 25. The movable plate 24 contacts the bottom surface of the limit ring 33 to hold the test tube 3. The spring 25 is still in a compressed state when the movable plate 24 contacts the limit ring 33. When the oscillation ends, the hook 32 is manually disengaged from the slot. At this time, the compressed spring 25 continues to reset, so that the test tube 3 moves upward and the top of the test tube 3 rises, which is convenient for the staff to take out the test tube 3. After the test tube 3 is taken out, the torsion spring drives the rotating plate 21 to reset. The rotating plate 21 and / or the movable plate 24 can contact the top surface and side wall of the groove 12 to scrape off the liquid flowing into the groove 12. At this time, the plate body 27 will extend into the through hole 26 to prevent the powder from clogging the through hole 26. The powder may remain in the through hole 26 when entering the through hole 26, causing the through hole 26 to be blocked. The plate body 27 only needs to be extended into the through hole 26 to slightly contact and squeeze the residual powder to avoid the blockage of the through hole 26.

[0058] In the second aspect, the embodiment of the present disclosure also provides a working method of the test tube stand for chemical experiments with the above-mentioned oscillation function, comprising: after placing the test tube 3 on the placement position formed by the support block 11 on the stand body 1, the bottom position of the test tube 3 is clamped by the clamping mechanism 2, and then the stand body 1 is vibrated by the vibration mechanism.

[0059] In summary, the test tube stand for chemical experiments with an oscillation function comprises: a stand body 1, on which are arranged a plurality of pairs of support blocks 11, with a gap between two support blocks 11, so as to form a placement station adapted to the size of the test tube 3 between the two support blocks 11; a clamping mechanism 2 is arranged at the bottom of the support block 11, and the clamping mechanism 2 is suitable for clamping the position of the test tube 3 near the bottom after the test tube 3 is placed in the placement station; a vibration mechanism is arranged on the stand body 1 to vibrate the stand body 1; so that when the test tube 3 is placed on the stand body 1, the bottom of the test tube 3 will be clamped, so as to avoid the bottom of the test tube 3 from colliding with the stand body 1 when the test tube 3 is oscillated, thereby avoiding damage to the test tube 3.
