[0021] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model. However, it should not be construed as a limitation on the protection scope of the present utility model.

[0022] Referring to Figures 1 to 4 , an embodiment of the present utility model provides a fecal quantitative collection device, which includes a tube cap 1. The outer shape of the tube cap 1 is hexagonal prism-shaped, with a cavity inside. The cavity is cylindrical. Threads are provided on the inner side surface of the tube cap 1, and anti-slip lines 2 in the vertical direction are provided on the outer side surface of the tube cap 1. A breakable blocking ring 3 is fixedly connected to the lower end surface of the tube cap 1. The breakable blocking ring 3 is annular, and a number of uniform rectangular through holes are provided on the surface of the breakable blocking ring 3. A storage device is threadedly connected inside the tube cap 1, and a quantitative collection device is movably connected to the storage device. The anti-slip lines 2 in the form of vertical bars are provided on the outer surface of the tube cap 1, which can prevent slipping during the sampling process and resulting in loss of samples. The breakable blocking ring 3 is fixed below the tube cap 1 to protect the sealing and hygiene of the sampling device before use. The quantitative collection device is convenient for accurately taking out the required amount of samples for collection, preventing the accuracy of the test results from being affected due to improper amount of collection. The storage device is used to store the sampled specimens to prevent the nature of the samples from being affected by external factors.

[0023] The storage device includes a fixed bracket 401, a cutting edge 402, a sample collection tube 403, a fixed tube 404, a limiting ring 405, and a preservation liquid 406. The fixed bracket 401 is circular ring-shaped. Two identical cutting edges 402 are fixedly connected to two opposite positions on the lower surface of the fixed bracket 401. The sample collection tube 403 has a cavity inside, and the cavity is cylindrical. The cutting edge 402 is vertically downward. When the tube cap 1 rotates downward, the cutting edge 402 will also rotate, thereby breaking the tin foil 505, so that the collected samples can pass through the tin foil 505 and fall into the preservation liquid 406 inside the sample collection tube 403.

[0024] The upper end surface of the sample collection tube 403 is fixedly connected to a fixed tube 404. Threads are provided on the outer side surface of the fixed tube 404. A limiting ring 405 is fixedly connected to the outer side surface of the sample collection tube 403 below the fixed tube 404. The limiting ring 405 can support the tube cap 1 upward to prevent excessive screwing in and damaging the sample collection tube 403.

[0025] A preservation liquid 406 is provided inside the sample collection tube 403. The preservation liquid 406 is used to protect the collected samples and facilitate the detection of the samples.

[0026] The quantitative collection device includes a sampling spoon 501, a storage chamber 502, a top ring 503, a support frame 504, and tinfoil 505. The storage chamber 502 is cylindrical with a cylindrical cavity inside. The diameter of the storage chamber 502 is slightly smaller than the diameter of the fixed tube 404. This slightly smaller diameter facilitates placement of the storage chamber 502 at the mouth of the fixed tube 404, allowing the sample to be placed. The sample is then taken to fill the storage chamber 502, and the tube cap 1 is screwed in. The blade 402 rotates to cut through the tinfoil 505 at the bottom of the storage chamber 502, allowing the sample to fall into the preservation solution 406, facilitating sample protection and extraction for testing.

[0027] Top ring 503 is annular in shape, with a diameter slightly larger than that of fixed tube 404, which in turn is slightly smaller than the diameter of the internal cavity of tube cap 1. This larger diameter facilitates positioning storage chamber 502 on the upper end of sample collection tube 403, securing it for easy sampling. Once sampling is complete, the blade 402 in tube cap 1 can be used to cut through tinfoil 505, allowing the sample to enter sample collection tube 403 and mix with preservation solution 406 for detection.

[0028] Several support brackets 504 arranged at equal angles are fixedly connected to the outer surface of the storage chamber 502. The outer diameter of the support brackets 504 is the same as the inner diameter of the fixed tube 404. This equal size facilitates the attachment of the storage chamber 502 to the upper end of the sample collection tube 403, preventing the sample from coming into contact with the preservation solution 406 until the sample is collected. After the storage chamber 502 is filled, the tube cap 1 is manually rotated, causing the internal fixed bracket 401 to rotate and drive the blade 402 to cut through the tinfoil 505, allowing the sample to enter the sample collection tube 403 and mix with the preservation solution 406 to achieve the desired detection effect.

[0029] Working principle: Before collection, first take out the sample collection tube 403, rotate the tube cover 1 to break the breakable blocking ring 3, remove the tube cover 1, and then take out the sampling spoon 501 to start sampling. When the sample fills the storage cavity 502, the quantitative collection is completed. Tighten the tube cover 1 so that the fixed bracket 401 inside the tube cover 1 drives the blade 402 to rotate to cut the tin foil 505 at the bottom of the storage cavity 502, allowing the sample to fall into the preservation solution 406. Then turn the sample collection tube 403 upside down several times to fully mix it, and the sampling process is completed.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
