[0050] First Embodiment

[0051] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 ,in, Figure 1 This is a schematic diagram of the structure of a first embodiment of a liquid sample collection tube for microbial testing provided by the present invention; Figure 2 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 3 for Figure 1 The diagram shows a three-dimensional structure of the liquid sample collection tube from a first-view perspective. Figure 4 for Figure 3 The enlarged schematic diagram of section B is shown below; Figure 5 for Figure 1 The diagram shows a three-dimensional structure of the liquid sample collection tube from a second perspective. Figure 6 for Figure 5 The enlarged schematic diagram of section C is shown. A liquid sample collection tube for microbial testing includes:

[0052] Circular mounting base 1, telescopic rod 2, rotating base 12, base 3, two connecting placement racks 4, multiple placement components 5, multiple movable components 6, moving component 7, rotating component 8, and extraction component 13;

[0053] The telescopic rod 2 is connected to the center of the bottom of the circular mounting base 1;

[0054] The rotating seat 12 is connected to the bottom of the telescopic rod 2;

[0055] The base 3 is connected to the bottom of the rotating seat 12;

[0056] The two connecting brackets 4 are symmetrically arranged on the upper and lower sides of the surface of the telescopic rod 2;

[0057] Multiple placement components 5 are respectively disposed between two connecting placement frames 4. Each placement component 5 includes a sampling bottle 51 and a connecting cap 52. The sampling bottle 51 is snapped between the two connecting placement frames 4, and the connecting cap 52 is threaded to the top of the sampling bottle 51.

[0058] Multiple active components 6 are respectively disposed between multiple sampling bottles 51 and multiple connecting caps 52;

[0059] The movable component 7 is disposed on one side of the circular mounting base 51;

[0060] The rotating component 8 is disposed on one side of the moving component 7;

[0061] The extraction component 13 is disposed at the bottom of the base 3.

[0062] The movable component 6 includes a threaded extraction rod 61, a threaded sleeve 62, and a toothed ring 63. The threaded extraction rod 61 is disposed between the sampling bottle 51 and the connecting cap 52. The threaded sleeve 62 is disposed on the surface of the threaded extraction rod 61, and the toothed ring 63 is disposed on the surface of the threaded sleeve 62.

[0063] The threaded extraction rod 61 consists of a threaded rod and an extraction head.

[0064] The movable component 7 includes a U-shaped movable base 71, two arc-shaped movable blocks 72 and two annular movable grooves 73. The two arc-shaped movable blocks 72 are respectively connected to the top and bottom of the inner wall of the U-shaped movable base 71, and the two annular movable grooves 73 are respectively opened on the upper and lower surfaces of the circular mounting base 1.

[0065] The rotating assembly 8 includes a rectangular plate 81, a movable groove 82, a movable seat 83, a gear 84, and a rotating handle 85. The rectangular plate 81 is connected to one end of the U-shaped movable seat 71. The movable groove 82 is formed on the surface of the rectangular plate 81. The movable seat 83 is disposed inside the movable groove 82. The gear 84 is rotatably connected to the top of the movable seat 83 via a rotating shaft. The rotating handle 85 is connected to the surface of the gear 84.

[0066] The movable slot 82 and movable seat 83 can be used when the sampling bottle 51 is rotated and replaced, by separating the gear 84 from the toothed ring 63 on the surface of one of the threaded sleeves 62, and then engaging with the toothed ring 63 on the other threaded sleeve 62 after the sampling bottle 51 is replaced.

[0067] Both of the connecting placement racks 4 are provided with multiple rubber pads 9 inside. The bottom of the sampling bottle 51 is connected to a connector 15. The surface of the sampling bottle 51 is provided with scale lines 11. The surface of the connector 15 is provided with a control valve 16.

[0068] The use of control valve 16 can prevent liquid leakage from connector 15, and the use of rubber pad 9 can increase the friction between sampling bottle 51 and connection placement rack 4.

[0069] The extraction assembly 13 includes an installation head 131, a connecting tube 132, an extraction head 133, and a bracket 134. The installation head 131 is installed on one side of the surface of the base 3, the connecting tube 132 is connected to the bottom of the installation head 131, the extraction head 133 is connected to one end of the connecting tube 132, and the bracket 134 is connected between the extraction head 133 and the base 3.

[0070] The connecting pipe 132 is a flexible hose, and the handle 14 makes it easy for the operator to pick it up.

[0071] A handle 14 is connected to one side of the telescopic rod 2.

[0072] The working principle of the liquid sample collection tube for microbial testing provided by this invention is as follows:

[0073] In use, when sampling a sample, first, the extraction head 133 contacts the sample, and then the rotating handle 85 drives the gear 84 to rotate. When the gear 84 rotates, it drives the toothed ring 63 on one side to rotate. When the toothed ring 63 rotates, it drives the threaded sleeve 62 to rotate. When the threaded sleeve 62 rotates, it drives the threaded extraction rod 61 to move upward. When the threaded extraction rod 61 moves upward inside the sampling bottle 51, the sample is transported to the inside of the sampling tube 51 through the extraction head 133, connecting tube 32, mounting head 131 and connecting head 15. After the sampling tube 51 has collected a suitable volume of sample, the control valve 16 is closed and the rotation of the rotating handle 85 is stopped.

[0074] When replacing the sampling bottle 51, first pull the circular mounting base 1 upwards, and it will move upwards under the action of the telescopic rod 2. When the telescopic rod 2 and the circular mounting base 1 move upwards, multiple sampling bottles 51 will move upwards through the two connecting placement brackets 4. When one of the sampling bottles 51 moves upwards, the bottom connector 15 will separate from the mounting head 131. After the bottom connector 15 of one of the sampling bottles 51 separates from the mounting head 131, multiple sampling bottles 51 will rotate through the rotating seat 12. When an unused sampling bottle 51 moves above the mounting head 131, push the circular mounting base 1 downwards to connect the bottom connector 15 of the sampling bottle 51 to the mounting head 131, and then open the control valve 16 to perform the sampling operation.

[0076] This invention provides a liquid sample collection tube for microbial testing. Two connecting placement racks 4, multiple placement components 5, and multiple movable components 6 are provided on the surface of a telescopic rod 2 with a circular mounting base 1, a rotating base 12, and a base 3, in conjunction with a moving component 7 with a rotating component 8.
