DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figure 1-Figure 6The test sample shaking device comprises: a T-shaped seat 1 and a display rack 2 arranged above the T-shaped seat 1, and a plurality of placement grooves 3 are provided on the top of the display rack 2 for placing a plurality of test tubes 8, and convex plates 4 are fixed on both sides of the display rack 2, and square pillars 5 are fixed on the tops of the two convex plates 4, and the same clamping plate 6 is slidably installed on the two square pillars 5, and a plurality of limiting holes 7 are provided on the clamping plate 6, and the plurality of limiting holes 7 correspond to the plurality of placement grooves 3 up and down, respectively, for forming a clamping position for the test tube 8 to prevent it from tilting, and a plurality of limiting holes 7 are provided on each limiting hole 7. There are test tubes 8 in each of the two test tubes 8, and the bottoms of the multiple test tubes 8 extend into the multiple placement grooves 3 respectively, and a sealing plate 9 is fixed on the clamping plate 6 by bolts, and the bottom of the sealing plate 9 contacts the tops of the multiple test tubes 8 to block the openings of the test tubes 8. Two cylinders 10 are fixed on the top of the T-shaped seat 1, and the tops of the two cylinders 10 are fixed with limit plates 12. Slide seats 11 are slidably installed on the two cylinders 10. The sides of the two slide seats 11 close to each other are fixedly connected to the display rack 2, and are fixed at the bottoms of the two limit plates 12. The bottom of the two shock-absorbing pads 13 are in contact with the two slides 11 respectively, and two springs 14 are fixed at the bottom of the display rack 2. The bottom ends of the two springs 14 are fixedly connected to the T-shaped seat 1, so that the display rack 2 can be lowered by pressing the slide 11 downward. At this time, the springs 14 are in a compressed state. When the pressure on the slide 11 is removed, the compressed springs 14 release the elastic force, so that the two slides 11 rise quickly and collide with the corresponding shock-absorbing pads 13, so that the test tubes 8 on the display rack 2 appear upward. The sample inside the T-shaped seat 1 is shaken downward so as to be shaken evenly, and a back plate 15 is fixed on the top of the T-shaped seat 1, on which two driven shafts 16 are rotatably mounted, and two driven shafts 16 are fixedly sleeved with double-headed cams 17, which are respectively matched with two slides 11, and the double-headed cams 17 are driven to rotate by the rotation of the driven shafts 16. When the protruding head of the double-headed cam 17 contacts the slide 11, the slide 11 is lowered, and when the two are separated, the slide 11 automatically rises under the action of the spring 14.

[0024] In the above manner, in order to be able to drive the two driven shafts 16 to rotate simultaneously and in opposite directions, two support plates are fixed on one side of the back plate 15, and the same driving shaft 18 is rotatably installed on the two support plates. Bevel gear 1 is fixed at both ends of the driving shaft 18, and bevel gear 2 is fixed at one end of the two driven shafts 16 close to the driving shaft 18, and the two bevel gears 1 are respectively meshed with the two bevel gears 2, and a mounting plate is fixed on one side of the back plate 15. The driving shaft 18 passes through the mounting plate and is movably connected to the mounting plate, and a motor is fixed on the mounting plate. The output shaft and the driving shaft 18 are fixedly sleeved with round teeth, and the two round teeth are meshed. Through the operation of the motor, the meshing between the round teeth and the meshing between the bevel teeth 1 and the bevel teeth 2 can drive the two driven shafts 16 to rotate simultaneously and in opposite directions, so that the two double-headed cams 17 are synchronized.

[0025] In this embodiment, in order to adjust the height of the clamping plate 6 and the sealing plate 9 according to the height of the test tube 8 to improve the scope of application, a plurality of adjustment slots 19 are provided on the side away from each other of the two square pillars 5, and square rods 20 are fixed on both sides of the clamping plate 6, and pull rods 21 are slidably mounted on the two square rods 20, and positioning heads 22 are fixed on the side where the two pull rods 21 are close to each other, and the ends of the two positioning heads 22 that are away from each other extend into the corresponding adjustment slots 19, and the clamping formed by the two can reliably fix the clamping plate 6. The height is limited to a specified height, and a side block is fixed at the ends of the two square rods 20 that are away from each other. The two square rods 20 are sleeved with a top spring. The ends of the two top springs that are close to each other are respectively fixedly connected to the two pull rods 21, and the ends that are away from each other are respectively fixedly connected to the two side blocks. In this way, the top force of the top spring can be used to firmly support the positioning head 22 in the adjustment groove 19, and a pull rod is fixed on the side of the two pull rods 21 that are away from each other. The two pull rods are both located below the square rods 20 to facilitate people pulling the pull rods 21.

[0026] The working principle of the test sample shaking device provided by the utility model is as follows:

[0027] When the sample is shaken, the sealing plate 9 is first removed from the card plate 6, and then the multiple test tubes 8 are respectively inserted into the multiple limiting holes 7 and placed into the corresponding placement grooves 3, and then the sealing plate 9 is installed on the card plate 6, so as to block the end openings of the test tubes 8;

[0028] Then, the motor is started, and the driving shaft 18 is driven to rotate by the meshing of the two round teeth, and then the meshing of the bevel teeth 1 and 2 is used to drive the two driven shafts 16 to rotate, so that the two double-headed cams 17 rotate. When the protruding heads of the two double-headed cams 17 contact the corresponding slides 11, the two slides 11 are lowered, and the display rack 2 is lowered at the same time. At this time, the spring 14 is in a compressed state, until the protruding heads of the double-headed cams 17 are separated from the slide 11, the compressed spring 14 releases its elastic force, and the slide is quickly moved. The two slides 11 and the display rack 2 are brought upward, and finally the two slides 11 collide with the two shock-absorbing pads 13, thereby generating vibrations, causing the sample in the test tube 8 to shake up and down, until the protruding head of the double-headed cam 17 contacts the slide 11 again, and the display rack 2 is brought down again. When separated, the display rack 2 will rebound and rise quickly, and this reciprocating cycle is repeated until the test tube 8 is shaken up and down for many times and then the motor is turned off. At this time, the sample in the test tube 8 is shaken evenly, and the shaking effect is achieved. After that, the test tube 8 can be taken out for inspection;

[0029] In subsequent use, when the test tube 8 with the sample inside that needs to be shaken is higher, in order to ensure that the sealing plate 9 can still seal the end opening of the test tube 8, the two pull rods can be pulled away from each other, and the two positioning heads 22 will move away from each other and move out of the corresponding adjustment slots 19. At this time, the two top springs are in a compressed state, and then the card plate 6 is slid upward. After the card plate 6 is moved to the specified height, the pulling force on the pull rod is slowly removed, and finally the two positioning heads 22 are inserted into the adjustment slots 19 at the corresponding positions, thereby completing the card plate 6 and height adjustment, and then the test tube 8 can be installed and shaken in the same way as above.

[0030] Compared with the related art, the test sample shaking device provided by the utility model has the following beneficial effects:

[0031] The utility model provides a sample shaking device for testing. By arranging a plurality of placement slots 3 on a display rack 2, samples in a plurality of test tubes 8 can be shaken at one time, thereby greatly improving the efficiency of shaking the test samples. In addition, the positions of the clamping plate 6 and the sealing plate 9 can be adjusted according to the height of the test tube 8, so that the device can be suitable for shaking test tubes 8 of different heights, and has strong applicability.
