[0022] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0023] Combined with Figure 1 , a blood collection cup centrifugal fixing device of the present invention includes a centrifuge body 1 and a fixed frame 2 arranged in the inner cavity of the centrifuge body 1. Placing cylinders 3 are fixedly installed at the four corners of the fixed frame 2, and blood collection cup bodies 4 are inserted into the inner cavities of the placing cylinders 3. Positioning assemblies 5 are installed on the outer sides of the blood collection cup bodies 4. The setting of the placing cylinders 3 facilitates the placement of the blood collection cup bodies 4, and the setting of the positioning assemblies 5 can clamp and fix the blood collection cup bodies 4 to improve the stability during centrifugation.

[0024] The present invention will be further described below in conjunction with the embodiments.

[0025] Embodiment 1:

[0026] Please refer to Figure 2 - Figure 5 , the clamping mechanism 51 includes arc-shaped clamping plates 511 fitted and installed on both sides of the blood collection cup body 4 and protection pads 512 fixedly installed on the inner sides of the arc-shaped clamping plates 511. The outer sides of the arc-shaped clamping plates 511 and the inner cavities of the blood collection cup bodies 4 are elastically connected through a plurality of telescopic springs 513. The clamping and positioning of the blood collection cup body 4 can be realized through the mutual cooperation of the arc-shaped clamping plates 511 and the telescopic springs 513, and the telescopic springs 513 can elastically clamp the blood collection cup body 4 by the arc-shaped clamping plates 511. In addition, the setting of the protection pads 512 can play a protective role.

[0027] A plurality of telescopic springs 513 are linearly arranged from top to bottom. The setting of the telescopic springs 513 can improve the clamping effect of the arc-shaped clamping plates 511.

[0028] The guiding mechanism 52 includes a connecting rod 521 fixedly installed at the bottom of the arc-shaped clamping plate 511 and a roller 522 fixedly installed at the lower end of the connecting rod 521. Rolling grooves 523 are respectively formed on both sides of the inner cavity bottom surface of the placing cylinder 3, and the output ends of the rollers 522 are respectively slidably installed in the inner cavities of the rolling grooves 523. The arrangement of the rollers 522 and the rolling grooves 523 can play a role in guiding the movement of the arc-shaped clamping plate 511.

[0029] Specifically, during use, the blood collection cup body 4 can be placed into the inner cavity of the placing cylinder 3. When placed, it will squeeze the two arc-shaped clamping plates 511 in the inner cavity of the placing cylinder 3. At this time, the blood collection cup body 4 will contact the protective pads 512 on the inner sides of the arc-shaped clamping plates 511, and at the same time, it will also squeeze the telescopic springs 513. At this time, the arc-shaped clamping plates 511 will clamp and fix the blood collection cup body 4. When the blood collection cup body 4 squeezes the arc-shaped clamping plates 511, it will cause them to move, thereby driving the rollers 522 to slide in the inner cavities of the rolling grooves 523 through the connecting rod 521. At this time, it can play a role in guiding the movement of the arc-shaped clamping plates 511.

[0030] Embodiment 2:

[0031] Please refer to Figure 1 - Figure 5 The positioning assembly 5 includes a clamping mechanism 51 and a guiding mechanism 52 installed on the clamping mechanism 51. The clamping mechanism 51 is provided to drive the guiding mechanism 52 to move to the set position. The guiding mechanism 52 is provided to be used for guiding and positioning to assist in the development of the positioning work. Through the mutual cooperation of the clamping mechanism 51 and the guiding mechanism 52, the blood collection cup body 4 can be clamped and positioned, improving the stability during centrifugation.

[0032] Support blocks 31 are fixedly installed in the middle of the inner cavity bottom surface of the placing cylinder 3, and the tops of the support blocks 31 are respectively fitted and installed on the outer side walls of the blood collection cup body 4. The arrangement of the support blocks 31 can play a role in supporting the blood collection cup body 4.

[0033] L-shaped lifting rods 41 are fixedly installed on both sides of the top of the blood collection cup body 4, and the tops of the L-shaped lifting rods 41 respectively extend to the outside of the placing cylinder 3. The arrangement of the L-shaped lifting rods 41 can facilitate the lifting of the blood collection cup body 4 and facilitate the taking out of the blood collection cup body 4.

[0034] Specifically, when the blood collection cup body 4 is placed into the inner cavity of the placing cylinder 3, it will contact the support blocks 31, so that the support blocks 31 play a role in supporting the blood collection cup body 4. The arrangement of the L-shaped lifting rods 41 can facilitate the taking out and placing of the blood collection cup body 4 and facilitate the development of the centrifugation work.

[0035] In summary, during use, the blood collection cup body 4 can be placed into the inner cavity of the placement cylinder 3. When placed, it will squeeze the two arc-shaped clamping plates 511 in the inner cavity of the placement cylinder 3. At this time, the blood collection cup body 4 will contact the protective pad 512 on the inner side of the arc-shaped clamping plate 511, and at the same time, it will also squeeze the telescopic spring 513. At this time, the arc-shaped clamping plate 511 will clamp and fix the blood collection cup body 4. When the blood collection cup body 4 squeezes the arc-shaped clamping plate 511, it will move, thereby driving the roller 522 to slide in the inner cavity of the rolling groove 523 through the connecting rod 521. At this time, it can play a guiding role in the movement of the arc-shaped clamping plate 511. When the blood collection cup body 4 is placed into the inner cavity of the placement cylinder 3, it will contact the support block 31, so that the support block 31 plays a role in supporting the blood collection cup body 4. The setting of the L-shaped lifting rod 41 can facilitate the removal and placement of the blood collection cup body 4, facilitating the development of the centrifugation work.
