DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] Example 1: This example 1 provides a slanted culture medium placement rack, which is directly improved on the existing culture medium placement rack and has a unique structure. Please refer to Figure 1-4 As shown, it includes a U-shaped frame 1, a U-shaped frame 2, an air pump 7 and a driving assembly. A placement plate 3 is fixedly installed on the upper part of the U-shaped frame 2. A plurality of vertically arranged through holes are opened on the top of the placement plate 3, and an annular air bag 4 is installed in the through holes; a plurality of arc-shaped grooves 5 are opened on the upper surface of the bottom of the U-shaped frame 2, and the grooves 5 correspond to the through holes one by one, and the plurality of through holes are distributed in a rectangular array.

[0019] A U-shaped cavity 10 is opened inside the placement plate 3, and the cavity 10 is connected to the annular airbag 4. A mounting hole connected to the cavity 10 is opened on the right side wall of the placement plate 3; there are various ways to connect the cavity 10 with the annular airbag 4, for example: a plurality of air intake channels connected to the cavity 10 are opened inside the placement plate 3, and a connecting pipe 6 is installed in the air intake channel, and the other end of the connecting pipe 6 is connected to the annular airbag 4.

[0020] A connecting pipe 6 is fixedly installed on the right side of the U-shaped frame 1. The connecting pipe 6 is concentrically arranged with the mounting hole. One end of the connecting pipe 6 is connected with the air pump 7, and the other end extends into the mounting hole and is sleeved with a sealing sleeve 8. The sealing sleeve 8 is in close contact with the inner wall of the mounting hole; the mounting hole is a countersunk hole, and a bearing is sleeved in the large end of the countersunk hole. The connecting pipe 6 is rotatably connected to the U-shaped frame 2 through the bearing, and the sealing sleeve 8 is sleeved on the connecting pipe 6 in the small end of the countersunk hole; the bearing can increase the stability of the U-shaped frame 2 during rotation, and the sealing sleeve 8 can improve the sealing of the mounting hole to prevent gas leakage.

[0021] A one-way air inlet valve 9 is fixedly installed inside the connecting tube 6, and an exhaust port connected to the cavity 10 is opened on the top of the placement plate 3, and an exhaust valve 11 is arranged in the exhaust port. Through the setting of the one-way air inlet valve 9 and the exhaust valve 11, when the annular airbag 4 expands to a suitable position, the air pump 7 is closed. At this time, the one-way air inlet valve 9 can prevent the high-pressure gas from flowing back, so that the annular airbag 4 always remains in an expanded state. When the culture medium solidifies, the exhaust valve 11 is pressed to discharge the gas in the annular airbag 4, which can not only make multiple annular airbags 4 shrink at the same time, but also prevent the air pump 7 from being in an open state all the time, thereby extending the service life of the air pump 7.

[0022] A rotating shaft is rotatably installed on the left side of the U-shaped frame 1, and the rotating shaft is concentrically arranged with the connecting pipe 6. One end of the rotating shaft is transmission-connected to the driving assembly, and the other end extends into the U-shaped frame 1 and is fixedly connected to the U-shaped frame 2; there are various ways to install the connecting pipe 6 and the rotating shaft, for example: through holes are opened on the left and right side walls of the U-shaped frame 1, the connecting pipe 6 is fixedly sleeved in the right through hole, both ends of the connecting pipe 6 extend out of the right through hole, and are respectively connected to the cavity 10 and the air pump 7, and the rotating shaft is rotatably sleeved in the left through hole through a bearing.

[0023] The driving assembly includes an electric motor 15 and a driving box 12, in which a worm 14 is rotatably installed, and the worm 14 is transmission-connected to the electric motor 15. One end of the rotating shaft away from the U-shaped frame 2 extends into the driving box 12 and is provided with a worm gear 13, which meshes with the driving box 12 for transmission. There are various transmission connection modes between the worm 14 and the electric motor 15, for example: the driving box 12 and the electric motor 15 are both fixedly installed on the left side wall of the U-shaped frame 1, and one end of the worm 14 passes through the driving box 12 and is fixedly connected to the electric motor 15 through a coupling.

[0024] When the operator uses the placement rack, he first inserts the test tube containing liquid culture medium into the inner hole of the annular airbag 4, and makes the bottom of the test tube rest against the bottom of the groove 5, and then starts the air pump 7. The air pump 7 fills the cavity 10 with high-pressure gas through the connecting tube 6. The high-pressure gas enters the annular airbag 4 through the air inlet channel respectively, so that the annular airbag 4 expands, thereby clamping and fixing the test tube. When the annular airbag 4 expands to a suitable position, the air pump 7 is turned off. At this time, the one-way air inlet valve 9 can prevent the high-pressure gas from flowing back, so that the annular airbag 4 always remains in an expanded state, and the air pump 7 is prevented from being in an open state all the time, thereby extending the service life of the air pump 7.

[0025] Start the motor 15, the motor 15 drives the worm 14 to rotate, and drives the worm wheel 13 to rotate through meshing transmission, thereby driving the U-shaped frame 2 to rotate, so that the liquid level of the liquid culture medium in the test tube is tilted, and the growth surface of the bacteria is increased. When the liquid culture medium solidifies, the output shaft of the motor 15 is reversed, the U-shaped frame 2 is restored to the initial state, and the exhaust valve 11 is pressed to exhaust the gas in the annular airbag 4, and then the test tube can be taken out.

[0026] Embodiment 2: Embodiment 2 is different from Embodiment 1 in that Figure 4 As shown, a plurality of suction cups 16 are fixedly installed at the bottom of the U-shaped frame 1. The plurality of suction cups 16 are symmetrically distributed in a rectangular shape, thereby increasing the stability of the placement rack and preventing the placement rack from tipping over during the rotation of the U-shaped frame 2.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
