[0025] Please refer to Figures 1-5 .

[0026] The present application provides a kind of flora PCR detection sample collection device technical scheme: a kind of flora PCR detection sample collection device, it is applied in flora PCR detection process, including collection test tube 1 and the collection swab 2 of being composed of sealing cover 201 and swab body 202, still include: setting in the lock assembly 3 of collection test tube 1 upper end;Limiting assembly 4 is set between sealing cover 201 and swab body 202, to cooperate with lock assembly 3 and stabilize the closure collection test tube 1.

[0027] By setting the collection test tube 1, the collection swab 2, the blocking assembly 3 and the limiting assembly 4, the collection swab 2 and the collection test tube 1 are tightly connected through the cooperation between the blocking assembly 3 and the limiting assembly 4. When the collection test tube 1 is impacted, the collection swab 2 can still be firmly clamped in the collection test tube 1, and the bacterial information in the collection test tube 1 will not leak out due to shaking of the collection test tube 1, and foreign matter cannot enter the inside of the collection test tube 1, thereby ensuring the safety and stability of the detection sample collection. Meanwhile, the blocking assembly 3 can be manually opened, so that the collection information can be taken out without affecting the experiment personnel when needed.

[0028] In an embodiment, the limiting assembly 4 includes a rubber ring 401 fixedly arranged between the sealing cover 201 and the swab body 202, and a limiting buckle 402 fixedly arranged on one side of the sealing cover 201. The inner side wall of the collection test tube 1 is provided with a sealing groove 101 matched with the rubber ring 401.

[0029] In this way, the rubber ring 401 has a certain elasticity, which can fully fill the sealing groove 101 in the collection test tube 1 when the sealing cover 201 is completely covered on the upper end of the collection test tube 1. The rubber ring 401 and the sealing groove 101 are arranged to prevent the bacterial information in the collection test tube 1 from flowing out through the gap between the collection test tube 1 and the sealing cover 201 when the collection test tube 1 is tilted. The limiting buckle 402 is arranged to cooperate with the matching groove 3021 in the blocking assembly 3. The limiting buckle 402 and the sealing cover 201 are integrally injection molded, and both are made of plastic material. The end of the limiting buckle 402 away from the sealing cover 201 is provided in a trapezoidal cross section, and the end of the limiting buckle 402 away from the sealing cover 201 is provided in a trapezoidal cross section. The end of the limiting buckle 402 away from the sealing cover 201 is provided in a trapezoidal cross section. The end of the limiting buckle 402 away from the sealing cover 201 is provided in a trapezoidal cross section.

[0030] In an embodiment, the blocking assembly 3 includes a bottom ring 301 fixedly arranged on the outer side wall of the collection test tube 1 and a top ring 302. A matching groove 3021 matched with the limiting buckle 402 is arranged between the bottom ring 301 and the top ring 302. A top block 303 with a trapezoidal cross section is slidingly arranged between the upper end of the bottom ring 301 and the lower end of the top ring 302. The upper end of the top block 303 is provided with an extension spring 305 fixedly connected to the side wall of the top ring 302. The outer side walls of the bottom ring 301 and the top ring 302 are provided with a push ring 304 which can slide. It should be noted that the outer side walls of the bottom ring 301 and the top ring 302 are provided with protrusions for blocking the push ring 304. In this way, the push ring 304 can only slide within a certain range, so that it will not directly slide out of the outer side walls of the bottom ring 301 and the top ring 302 under the action of external force.

[0031] In this way, when the colony information is collected by the collection swab 2, the swab body 202 is inserted into the inside of the collection test tube 1, and the sealing cover 201 is pressed downward, at this time, the limiting buckle 402 on one side of the sealing cover 201 enters the matching groove 3021 between the bottom ring 301 and the top ring 302 along the gap between the top ring 302 and the collection test tube 1, and the rubber ring 401 completely fills the sealing groove 101 in the collection test tube 1, at this time, the stable sealing between the collection test tube 1 and the collection swab 2 is completed, and when the collection swab 2 needs to be taken out, the push ring 304 is only pressed downward, when the push ring 304 moves downward, the top block 303 with a trapezoidal cross section is squeezed, the top block 303 is squeezed and moves between the bottom ring 301 and the top ring 302 towards the collection test tube 1, at this time, the extension spring 305 is compressed, and the top block 303 squeezes the limiting buckle 402, when the limiting buckle 402 is squeezed to the other side of the matching groove 3021, the swab body 202 is pulled out of the collection test tube 1 through the sealing cover 201.

[0032] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
