Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 4 The low-temperature constant temperature bath with circulating pump stirring shown is characterized by comprising: a housing 1, an opening 2 connected above the housing 1, a placement groove 3 fixedly provided in the opening 2, a placement rack 4 for placing containers provided in the placement groove 3, a lifting part 6 movably provided on the placement rack 4, a clamping part 5 for clamping and fixing containers provided on the placement rack 4, a moving mechanism 7 for moving the lifting part 6 on the placement rack 4, a driving mechanism 8 for driving the clamping part 5 on the placement rack 4, a circulating pump 31 connected to the bottom of the placement groove 3, a constant temperature device 32 provided above the housing 1, and a cover plate 33 movably hinged to the opening 2.

[0018] In the above-described circulating pump agitated low-temperature constant temperature bath, the user places the container on the placement rack 4, and then the moving mechanism 7 drives the lifting part 6 to move, thereby raising the lifting part 6 to a position where the container can be lifted. Then, the driving mechanism 8 drives the clamping part 5 to clamp and fix the container. In daily use, the constant temperature device 32 maintains the temperature of the medium in the placement tank 3, and at the same time, the circulating pump 31 agitates the medium. Compared with the prior art, the existing low-temperature constant temperature bath can prevent the impact force of the water flow from the circulating pump from knocking over the container during use, and can also be adapted to containers of different sizes.

[0019] like Figure 3 and 4As shown, in some embodiments of this utility model, the placement rack 4 includes a fixed frame 41 fixed to the bottom of the placement groove 3. Support rods 42 are fixed around the fixed frame 41. A connecting plate 43 is fixed above each support rod 42. Placement holes 44 are symmetrically provided on the connecting plate 43. An installation frame 45 that can be fixed to the opening 2 is fixed to the upper end of each support rod 42. When the user places the utensil on the placement hole 44 of the connecting plate 43, it moves along the support rod 42 when the lifting part 6 moves. The fixed frame 41 is fixed to the bottom of the placement groove 3, and the installation frame 45 is fixed to the opening 2, so that the placement rack 4 is fixed as a whole.

[0020] like Figure 3 and 4 As shown, in some embodiments of this utility model, the lifting part 6 includes a movable plate 61 movably disposed above the fixed frame 41, with a plurality of mesh holes 62 provided on the plate, and guide grooves 63 provided around the movable plate 61. Each guide groove 63 is movably sleeved on the adjacent support rod 42. A guide rod 64 is fixedly disposed on the left side of the fixed frame 41, and a guide sleeve 65 that can be movably sleeved on the guide rod 64 is provided on the left side of the movable plate 61.

[0021] The moving mechanism 7 includes a first threaded sleeve 71 disposed on the right side of the moving plate 61, a first screw 72 that can be threadedly engaged with the first threaded sleeve 71 is movably sleeved between the right side of the fixed frame 41 and the connecting plate 43, and a first twist handle 73 is provided at the upper end of the first screw 72 and passing through the mounting frame 45.

[0022] When in use, the user rotates the first twist handle 73, which causes the first twist handle 73 to drive the first screw 72 to rotate. At this time, the first screw 72 drives the moving plate 61 to move through the first threaded sleeve 71, and the moving plate 61 moves along the support rod 42 through the guide groove 63. At the same time, the guide sleeve 65 moves along the guide rod 64.

[0023] like Figure 3 As shown, in some embodiments of this utility model, extension rods 81 are fixed around the sealing cover 8, and filter plates 82 are connected below each extension rod 81. When the solution is transported, impurities can be filtered through the filter plates 82 connected below the extension rods 81. After the soaking tank 1 is used, the user can pick up the sealing cover 8 and clean the filter plates 82.

[0024] like Figure 3 and 4As shown, in some embodiments of this utility model, the clamping part 5 includes slide rails 51 symmetrically arranged below the moving plate 61, and arc-shaped clamping plates 52 are movably inserted between each slide rail 51 and arranged on one side below each placement hole 44. An arc-shaped stop block 53 is provided on the other side below each placement hole 44.

[0025] The driving mechanism 8 includes a second screw 81 symmetrically and movably sleeved below the connecting plate 43. A first bevel gear 82 is fixed at one opposite end of each second screw 81. A second bevel gear 83 that can mesh with the first bevel gear 82 is movably sleeved in the middle of the rear side of the connecting plate 43. A second torsion handle 84 is fixed at the sleeved end of the second bevel gear 83. A second threaded sleeve 85 that can threadedly engage with the second screw 81 is provided on the rear side of each arc-shaped clamp 52.

[0026] In use, the user turns the second twist handle 84, which causes the second twist handle 84 to drive the second bevel gear 83 to rotate. At this time, the second bevel gear 83 drives each of the first bevel gears 82 to rotate. When the first bevel gears 82 rotate, they drive the second screw 81 to rotate. The second screw 81 then drives the arc-shaped clamping plate 52 to move through the second threaded sleeve 85. When the arc-shaped clamping plate 52 moves, it moves along the slide rail 51 until the arc-shaped clamping plate 52 clamps and sets the vessel on the arc-shaped stop block 53.

[0027] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
