Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the structure chart of pressurizing unit in the present invention；
Fig. 3 is partial enlarged view at the A at Fig. 1 in the present invention.
Specific embodiment
Below in conjunction with attached drawing, the invention will be further described.
Embodiment: as shown in Figure 1, 2, 3, a kind of vacuum blood collection tube, including test tube 1, cap test tube 2 and the cap test tube 2 are solid
Surely the test tube plug 3 that connects and the contact pin cavity 5 for being located at 3 top of test tube plug；Contact pin cavity 5 is used to insert convenient for blood taking needle
Entering, test tube plug is used to seal test tube, and is integrally formed with cap test tube, and it is easy to disassemble, all it is made of rubber；The cap test tube
2 are equipped with the pressurizing unit 4 for squeeze to the blood taking needle being inserted into the test tube plug 3 sealing, pass through pressurizing unit pair
Blood taking needle in insertion test tube plug 3 is squeezed, can be to the needle left to realize sealing, and after blood taking needle extraction
Hole carries out extruding sealing.
In the present invention, the pressurizing unit 4 includes the thread cavity 401 being located on the test tube plug 3, is screwed onto the screw thread
Extruding ring cavity 403 that rotating piston 402 and the thread cavity 401 in chamber 401 communicate, the left side being located in the extruding ring cavity 403
Side extrusion side 404 and right side extrusion side 405 are located on the rotating piston 402 and are used for and the left side extrusion side 404 is matched
The left side compressive plane 406 of conjunction and right compressive plane 407 for cooperating with the right side extrusion side 405；The rotating piston 402
It is equipped with blood taking needle and passes through mouth 408；For the ease of rotation, the rotating piston 402 is equipped with rotation and removes block 413, and quantity is two,
Internal screw thread is equipped in thread cavity, rotating piston is equipped with external screw thread, and then realizes being spirally connected for the two, when blood taking needle passes through rotating piston simultaneously
When insertion in test tube, rotating piston 402 is rotated, so that rotating piston moves down, so that left side compressive plane 406, the right side squeeze
Inclined-plane 407 is pressed to apply pressure to left side extrusion side 404, right side extrusion side 405 respectively, because, left side compressive plane 406, the right side
Compressive plane 407, left side extrusion side 404, right side extrusion side 405 are all anchor rings, are realized so internally squeezing to blood taking needle
Sealing, when blood taking needle extraction can be sealed pin hole, the sealing externally squeezed between realization test tube plug and inboard wall of test tube adds
By force.
Further, the pressurizing unit 4 further includes the lower ring cavity 409 communicated with the extruding ring cavity 403, positioned at described
Lower ring cavity 409, which neutralizes the crushing block 410 that the rotating piston 402 is fixedly connected and is located at the elasticity squeezed on fast 410, to incline
Inclined plate 411 carries out assisted extrusion to bloodletting needle and pin hole using elastic hang plate, for this purpose, the lower ring cavity 409 is equipped with and institute
State the extrusion side 412 that elastic hang plate 411 cooperates；The elasticity hang plate 411 and 410 side of the crushing block are at 30-45 °
Angle.
