DETAILED DESCRIPTION

[0022] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings of the specification and specific embodiments.

[0023] The embodiment of the present application discloses a water bath kettle for preheating culture medium, referring to Figure 1 , Figure 2 and Figure 3 , including a water bath kettle body 1, the water bath kettle body 1 is provided with a water bath tank 11, the water bath tank 11 is used for containing clean water, and the water bath kettle body 1 can constant-temperature heat the clean water in the water bath tank 11. The upper portion of the water bath kettle body 1 is provided with a kettle cover 2, the kettle cover 2 can be flexibly connected on the water bath kettle body 1 through buckling, and the kettle cover 2 can be used for covering the water bath tank 11. The floating frame 3 is placed in the water bath tank 11, the floating frame 3 can be made of PC or aluminum alloy into a hollow structure to increase the buoyancy, or the outer side can be wrapped with sponge or foam structure to make itself float. The floating frame 3 and the inner wall of the water bath tank 11 leave a movable gap, the floating frame 3 can be designed as a hollow structure, and the test tube can pass through the floating frame 3.

[0024] Referring to Figure 4On the floating frame 3, a plurality of groups of tube clamping assemblies 4 for clamping test tubes are arranged. Specifically, the tube clamping assembly 4 comprises two clamping petals 41 which are symmetrical to each other and are both rotationally installed on the floating frame 3. The floating frame 3 is provided with an elastic member for driving the movable ends of the two clamping petals 41 to approach each other. The floating frame 3 is provided with a limiting member for limiting the minimum opening distance of the movable ends of the two clamping petals 41. In the embodiment of the present application, the elastic member can be a first spring 42. The clamping petals 41 are integrally fixed with limiting pieces 43. The connection between the clamping petals 41 and the limiting pieces 43 is hinged to the floating frame 3. A strip-shaped hole 44 is formed through the limiting piece 43. An installation block is integrally fixed on the floating frame 3 between the limiting pieces 43 of the two clamping petals 41. The installation block is fixedly connected with a guide rod 45 which is arranged in the strip-shaped hole 44. The first spring 42 is sleeved on the guide rod 45. One end of the first spring 42 abuts against the installation block, and the other end abuts against the limiting piece 43. Under the pushing of the first spring 42, the movable ends of the two limiting pieces 43 can be pushed away from each other, and the movable ends of the two clamping petals 41 can be driven to approach each other. When it is necessary to clamp a test tube, the operator clamps the two limiting pieces 43 close to each other, so that the movable ends of the two clamping petals 41 are driven to open away from each other, and thus different sizes of test tubes can be inserted.

[0025] For test tubes made of relatively fragile or soft material, the limiting member can be used to limit the minimum opening size of the two clamping petals 41 which can be opened and closed, so that the test tube can be easily inserted between the two clamping petals 41, and the stress of the test tube in the clamped state is reduced. Specifically, the limiting member can be a limiting nut 46. An outer thread is arranged on the outer wall of the guide rod 45. The limiting nut 46 is threadedly connected with the guide rod 45, and abuts against the limiting piece 43 away from the first spring 42. The limiting nut 46 limits the maximum distance by which the limiting piece 43 is pushed to rotate by the spring, so as to limit the position of the two clamping petals 41 when the minimum opening size is reached. Further, the limiting nut 46 can be a butterfly nut, so as to facilitate the operator to rotate and adjust the limiting nut 46. Further, an elastic layer is arranged on the inner wall of the two clamping petals 41 which approach each other. The elastic layer can be a silica gel layer. After the minimum clamping size of the two clamping petals 41 is adjusted to be slightly larger than the size of the test tube, the test tube can be clamped by the friction and elastic force of the silica gel layer. The fragile material of the test tube can be adapted, and the stable clamping effect on the test tube can be maintained.

[0026] Reference Figure 5, further, in order to shake the test tube on the floating frame 3, so as to accelerate the preheating effect of the cells in the test tube, the cover 2 is further provided with a driving assembly for driving the floating frame 3 to reciprocating oscillate in the water bath tank 11, in the embodiment of the application, the driving assembly can be composed of a turntable 51, a push rod 52 and a driving motor 53. The turntable 51 is horizontally rotatably installed at the center of the cover 2, the driving motor 53 is fixedly installed on the cover 2 and used for driving the turntable 51 to rotate, the push rod 52 is located below the turntable 51 and is vertically slidably connected to the cover 2, the bottom wall of the turntable 51 is provided as an inclined surface, and the cover 2 is provided with a second spring 54 for driving the top end of the push rod 52 to abut against the turntable 51. The center of the floating frame 3 is integrally connected with a connecting plate 31, when the cover 2 is covered on the water bath pot body 1, the turntable 51 is located directly above the connecting plate 31, and the bottom end of the push rod 52 abuts against and slightly presses down the connecting plate 31 floating on the water surface in the water bath tank 11, so that each push rod 52 can contact the connecting plate 31, and with the rotation of the turntable 51, each push rod 52 can continuously rise and fall under the action of the turntable 51 and the second spring 54, thereby driving the floating frame 3 to continuously oscillate in the water bath pot body 1.

[0027] Further, the top end and the bottom end of the push rod 52 are both provided with a ball bearing 55, so that when the push rod 52 slides in contact with the connecting plate 31 or the turntable 51, the ball bearing 55 can reduce the friction and wear during the sliding abutment.

[0028] Further, in order to avoid the floating frame 3 from being misaligned relative to the turntable 51 during shaking, a positioning rod 56 is coaxially fixed on the bottom wall of the turntable 51, the bottom end of the positioning rod 56 is provided with a positioning ball 57, and a positioning groove 32 adapted to the positioning ball 57 is coaxially formed in the top wall of the connecting plate. When the cover 2 is covered on the water bath pot body 1, the positioning ball 57 cooperates with the positioning groove 32, so that the floating frame 3 rotates around the positioning ball 57 during shaking, avoiding the push rod 52 from sliding and misaligning on the connecting plate 31.
