[0020] Embodiment 1:
[0021] like Figure 1-Figure 3 As shown, a constant temperature water bath oscillator comprises a water bath oscillator body 1 and a discharging mechanism, wherein the discharging mechanism comprises an oscillating working box 11, the oscillating working box 11 is arranged on the top surface of the water bath oscillator body 1, the inside of the oscillating working box 11 is semi-open and has an oscillating inner groove 12, the inner side of the oscillating inner groove 12 is movably connected with a workbench 13, the top surface of the workbench 13 is provided with a test tube placement rack 14, the inner side of the test tube placement rack 14 is movably connected with a test tube placement sleeve 2, the outer side of the test tube placement sleeve 2 is provided with a connecting rod 21, the inner side of the oscillating inner groove 12 is provided with a limited position slide groove 15, the top of the oscillating working box 11 is provided with a connecting groove 1 6. The connecting groove 16 is connected to the limiting slide groove 15. A screw 17 is movably connected to the inner side of the limiting slide groove 15. One end of the screw 17 is located in the connecting groove 16 and penetrates the connecting groove 16 and is located outside the top of the oscillating working box 11. The outer side of one end of the screw 17 located inside the limiting slide groove 15 is threadedly connected with a threaded sleeve 22. One end of the threaded sleeve 22 is located inside the oscillating inner groove 12 and is fixedly connected to the connecting rod 21. Six test tube placement racks 14 are arranged around the top surface of the workbench 13. The number of test tube placement sleeves 2 is the same as that of the test tube placement racks 14, and a connecting rod 21 is arranged between each of the test tube placement sleeves 2.
[0022] Water bath oscillator is mainly suitable for oscillating culture of various liquid and solid compounds such as biology, biochemistry, cells, bacteria, etc. in universities, petrochemicals, health and epidemic prevention, environmental monitoring and other scientific research departments. It has the characteristics of reasonable structure, simple operation, high stability and performance, and is an ideal equipment for laboratory staff.
[0023] When the test tube is placed in the oscillator, in order to make the test tube more stable and prevent accidents such as tipping over during oscillation, it will be placed deep in the test tube placement rack, so that the exposed section of the test tube is shorter. When the test tube needs to be taken out, the small force section plus the liquid that may be attached to the outside of the test tube will make it difficult to take out the test tube, making it inconvenient to use;
[0024] First, place the test tubes one by one into the test tube placement sleeve 2, and then rotate the screw 17 to allow the screw 17 to rotate under the action of the bearing. At the same time, the threaded sleeve 22 slides inside the limiting slide groove 15 under the restriction of the limiting slide groove 15, so that the threaded sleeve 22 can slide down with the connecting rod 21 and the test tube placement sleeve 2 until the position of the test tube is adjusted to the right position, then the water bath oscillator body 1 is turned on to allow the test tube to be fully oscillated. When the oscillation operation is completed, the screw 17 is rotated in the opposite direction to allow the threaded sleeve 22 to slide and rise in the limiting slide groove 15, so that the test tube placement sleeve 2 and the test tube therein can be raised, and the exposed part of the test tube in the oscillation inner groove 12 increases. The staff then focuses on the exposed part of the test tube to take out the test tube;
[0025] The test tube can be kept deeply placed in the test tube placement rack 14. When the test tube needs to be taken out, the test tube placement sleeve 2 can drive the test tube to move upward, increase the exposed length of the test tube, increase the area for staff to exert force, avoid the test tube from slipping, and improve the safety of test tube taking.
[0026] In other embodiments, the present embodiment discloses, please Figure 3 As shown, an auxiliary rotating block 18 is provided on one end face of the screw rod 17 located outside the oscillation working box 11, and anti-slip grooves are provided on the outside of the auxiliary rotating block 18. Through this design, when the staff needs to rotate the screw rod 17, they can focus on the auxiliary rotating block 18 to drive it, which is more convenient to apply force.
[0027] In other embodiments, the present embodiment discloses, please Figure 3 As shown, the inner and outer sides of the threaded sleeve 22 and the outer side of the screw 17 are both provided with anti-rust paint, and rubber rings are arranged at equal distances on the outer side of the test tube placement sleeve 2; through this design, the service life of the threaded sleeve 22 and the screw 17 can be improved to prevent them from rusting quickly when in contact with water for a long time, and the rubber ring arranged on the outer side of the test tube placement sleeve 2 can improve the friction between the test tube placement sleeve 2 and the test tube placement rack 14 to a certain extent, thereby improving stability.
[0028] Embodiment 2:
[0029] In other embodiments, the present embodiment discloses, please Figure 2 , Figure 4As shown, it also includes an adjustment mechanism, which includes an empty slot 23, the empty slot 23 is opened inside the test tube placement sleeve 2, a spring 24 is arranged inside the empty slot 23, and a limit stopper 25 is arranged on the other end surface of the spring 24, one end of the limit stopper 25 passes through the empty slot 23 and is located inside the test tube placement sleeve 2, an auxiliary inner sleeve 3 is movably connected inside the test tube placement sleeve 2, a connecting slide groove 31 is opened outside the auxiliary inner sleeve 3, and one end of the limit stopper 25 is slidably connected to the inside of the connecting slide groove 31;
[0030] When a conventional test tube is placed in the test tube placement sleeve 2, the bottom end of the test tube first contacts the limit stopper 25, and the limit stopper 25 that is too exposed on the inner side of the test tube placement sleeve 2 is pushed inward, and the limit stopper 25 squeezes the spring 24. On the premise of resisting the test tube, the excess part of the limit stopper 25 returns to the inner side of the empty groove 23 to fix the test tube. When placing an unconventional ultra-thin test tube, first find the auxiliary inner sleeve 3 corresponding to the diameter of the ultra-thin test tube, and then slide the auxiliary inner sleeve 3 downward against the inner side of the test tube placement sleeve 2, and the limit stopper 25 slides inside the connecting slide groove 31 until the auxiliary inner sleeve 3 is put in place, and finally the ultra-thin test tube is placed inside the auxiliary inner sleeve 3. When placing test tubes of different thicknesses in the test tube placement sleeve 2, they can be arranged according to their thickness to make the test tube more stable. When placing test tubes of unconventional fineness, the auxiliary inner sleeve 3 can be plugged to improve the flexibility of use of the test tube placement sleeve 2.
[0031] In other embodiments, the present embodiment discloses, please Figure 2 , Figure 4 As shown, protective cotton is arranged at equal distances on the inner side of the auxiliary inner sleeve 3, four connecting grooves 31 are opened around the outer side of the auxiliary inner sleeve 3, and the number of limit stops 25 is the same as that of the connecting grooves 31; through this design, the connection between the auxiliary inner sleeve 3 and the test tube is safer, and the setting of multiple limit stops 25 and connecting grooves 31 can enhance the strength of the test tube placement sleeve 2 to reinforce the test tube, and can also enhance the tightness of the connection between the test tube placement sleeve 2 and the auxiliary inner sleeve 3.
