Abstract
The utility model discloses a novel virus sampling pipe relates to microorganism sampling conveying pipe technical field. The novel virus sampling tube comprises a tube body, a sealing cover for sealing the tube body and an oil seal ring; a stepped blind hole is formed in the pipe body, and the oil seal ring is arranged in a first hole of the stepped blind hole; a bulge is arranged at the center of the sealing cover and is matched with the second hole of the stepped blind hole; and a water-proof pad is arranged between the oil seal ring and the bottom of the through hole. The utility model discloses a multiple sealed mode, the in-process that has significantly reduced transported the virus sample produces the possibility that the virus revealed.
Description
Technical Field
The utility model relates to a microorganism sampling conveying pipe technical field, concretely relates to novel virus sampling pipe.
Background
The virus sampling tube is a centrifugal tube used for sampling viruses such as influenza virus, hand-foot-and-mouth virus and the like in the microorganism sampling and conveying tube, and is also called a specimen conveying tube; the virus sampling tube is loaded with infectious substances, and some of the substances are highly pathogenic infectious substances, so that the requirements on the virus sampling tube are very strict, and most importantly, the leakage cannot be generated in the process of using the virus sampling tube.
SUMMERY OF THE UTILITY MODEL
The utility model provides a novel virus sampling pipe using multiple sealing modes.
In order to solve the technical problem, the utility model provides a technical scheme as follows:
a novel virus sampling tube comprises a tube body, a sealing cover for sealing the tube body and an oil seal ring; a stepped blind hole is formed in the pipe body, and the oil seal ring is arranged in a first hole of the stepped blind hole; a bulge is arranged at the center of the sealing cover and is matched with the second hole of the stepped blind hole; and a water-insulating pad is arranged between the oil seal ring and the bottom of the through hole.
Furthermore, the joint of the second hole and the first hole is conical.
Further, a cavity is arranged inside the oil seal ring; the oil seal ring and the water-proof pad contact one end are in a conical structure, the other end is provided with an annular groove, and the inner wall of the seal cover is provided with an annular bulge corresponding to the annular groove.
Further, the material of the oil seal ring comprises rubber, thermoplastic polyurethane elastomer and plasticized polyvinyl chloride.
Compared with the prior art, the utility model discloses following beneficial effect has:
when the sealing cover is connected with the sealing groove, the oil seal ring is extruded and deformed, and the water-proof cushion is compacted to form sealing; the oil seal ring can form a layer of seal after being deformed; the sealing cover and the sealing groove are connected to have certain sealing performance; thus, a three-layer seal is formed, and the possibility of virus leakage in the process of conveying the virus sample is greatly reduced.
Drawings
FIG. 1 is a schematic view of the assembled cross-sectional structure of the novel virus sampling tube of the present invention;
fig. 2 is the schematic diagram of the cross-sectional structure of the tube body of the novel virus sampling tube of the present invention.
Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
The utility model provides a stable light source structure, as shown in fig. 1 and fig. 2, comprising a tube body 1, a sealing cover 2 for sealing the tube body and an oil seal ring 3; a stepped blind hole is formed in the pipe body, and the oil seal ring 3 is arranged in a first hole 1-1 of the stepped blind hole; a bulge is arranged at the center of the sealing cover 2, and the bulge of the sealing cover 2 is matched with the second hole 1-2 of the stepped blind hole; and a water-proof pad 4 is arranged between the oil seal ring 3 and the bottom of the through hole.
In this embodiment, as shown in fig. 2, the junction of the second hole 1-2 and the first hole 1-1 is tapered; the optimal angle between the conical surface and the plane is 30-60 degrees; the sampling cotton swab is convenient to scrape liquid at the side wall and the outlet position by an inclined angle.
In the embodiment, a cavity is arranged inside the oil seal ring 3; one end of the oil seal ring 3, which is in contact with the waterproof pad 4, is in a conical structure, the other end of the oil seal ring is provided with an annular groove, and the inner wall of the seal cover is provided with an annular bulge corresponding to the annular groove; through being connected of annular arch and ring channel, the assembly is accomplished the back the toper structure of oil blanket circle 3 is flattened, squeezes to account for the space of cavity and produces elastic deformation and produce the elasticity of reconversion simultaneously, crowds to account for the space through elasticity, increases the leakproofness.
Preferably, the material of the oil seal ring 3 comprises rubber, thermoplastic polyurethane elastomer, plasticized polyvinyl chloride; the elastic material is adopted, and better sealing effect is generated through deformation of the material.
Compared with the prior art, the utility model discloses following beneficial effect has:
when the sealing cover 2 is connected with the sealing groove 5, the oil sealing ring 3 is extruded and deformed, and the water-proof cushion 4 is compacted to form sealing; the oil seal ring 3 can form a layer of seal after being deformed; the connection between the sealing cover 2 and the sealing groove 5 also has certain sealing property; thus, a three-layer seal is formed, and the possibility of virus leakage in the process of conveying the virus sample is greatly reduced.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
