[0023] Embodiment 1:

[0024] The disposable venous blood sample collection container provided in the present application includes a blood collection container 1; a sealing cap 101 is installed at the top of the blood collection container 1, a rubber block 102 is provided inside the sealing cap 101, and a protection mechanism 3 is installed outside the blood collection container 1;

[0025] The protection mechanism 3 includes a snap ring 301, an arc plate 302, an arc plate 303 and a torsion spring 304. A snap ring 301 is installed outside the blood collection container 1, an arc plate 302 is rotatably installed at one end of the snap ring 301, an arc plate 303 is rotatably installed at the end of the snap ring 301 away from the arc plate 302, and torsion springs 304 are installed on both sides of the arc plate 302 and the arc plate 303;

[0026] Specifically, as Figure 1 , Figure 2 and Figure 3As shown, by inserting one end of the blood collection needle into the rubber block 102 inside the sealing cap 101, blood can flow into the inside of the blood collection container 1 under the action of the pressure difference for storage. The protection mechanism 3 is used to support the blood collection container 1 at the top. One end of the coil spring 304 is connected to the snap ring 301, and the other end is connected to the first arc plate 302 or the second arc plate 303. By unfolding the first arc plate 302 and the second arc plate 303 from one side of the snap ring 301 and flipping the two groups of the first arc plate 302 and the second arc plate 303, the snap ring 301, the first arc plate 302 and the second arc plate 303 can support one end of the blood collection container 1, so that the blood collection container 1 can be directly in an inclined state, which is convenient for better flowing of the blood into the inside of the blood collection container 1.

[0027] Furthermore, a clamping block 4 is installed on the inner top of the end of the first arc plate 302 far from the snap ring 301;

[0028] Specifically, as Figure 4 shown, in order to fix between the first arc plate 302 and the second arc plate 303, a groove corresponding to the clamping block 4 is provided on the top of the second arc plate 303.
