[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] Depend on Figure 1-8 This invention discloses a centrifuge with a refrigeration device, comprising a housing 1, a centrifuge mechanism 2 and a refrigeration mechanism 5 within the housing 1, a cooling pipe 3 externally disposed on the centrifuge mechanism 2, and a first connecting pipe 4 disposed on the cooling pipe 3, the refrigeration mechanism 5 located on one side of the centrifuge mechanism 2, and a second connecting pipe 6 disposed on the refrigeration mechanism 5, the first connecting pipe 4 and the second connecting pipe 6 communicating to allow refrigerant in the refrigeration mechanism 5 to enter the cooling pipe 3.

[0026] The end of the second connecting pipe 6 is provided with a pressure block 12, and an annular rubber pad 13 is provided on the pressure block 12. Multiple support frames 14 are provided on the rubber pad 13. One end of the support frame 14 is installed on the pressure block 12, and the support frames 14 are arranged radially. The support frames 14 can be flexibly bent.

[0027] A socket 15 is provided at the end of the first connecting pipe 4. The size of the socket 15 is smaller than that of the first connecting pipe 4. The pressure block 12 can be inserted into the socket 15. When the support frame 14 enters the socket 15, the end of the support frame 14 can be elastically bent. After the support frame 14 enters the first connecting pipe 4, the support frame 14 can be opened up against the vertical surface, and the annular rubber pad 13 is attached to the vertical surface.

[0028] When assembling this device or when the refrigeration mechanism needs to be disassembled, the user places the refrigeration mechanism 5 inside the equipment housing 1, and then fixes or disassembles the refrigeration mechanism 5 by connecting / disconnecting the first connecting pipe 4 and the second connecting pipe 6. With the cooperation of the pressure block 12, the rubber pad 13 and the support frame 14, the rubber pad 13 can be attached to the connection position, and the pressure block 12 and the support frame 14 can press on the surface of the rubber pad 13, thereby ensuring the sealing of the connection position.

[0029] The end of the second connecting pipe 6 has a bellows 7, which can be stretched or compressed, and the pressure block 12 is fixed to the end of the bellows 7 so that the pressure block 12 can extend and retract.

[0030] The corrugated pipe 7 is fitted with a sleeve 11, and a fixing block 10 is fixedly connected to the sleeve 11. The fixing block 10 is connected to the second connecting pipe 6 through a telescopic rod 9. The telescopic rod 9 is used to restrict the movement direction of the fixing block 10. The end of the sleeve 11 away from the fixing block 10 rests on the pressure block 12, and the sleeve 11 and the fixing block 10 are not connected to each other.

[0031] The telescopic rod 9 may have a fixed section and a telescopic section. One end of the fixed section has a blind hole, and the other end is fixedly connected to the second connecting pipe 6. One end of the telescopic section is inserted into the blind hole, and the other end is fixedly connected to the fixed block 10.

[0032] A sliding groove 23 is provided on the pressure block 12. The support frame 14 is fixedly and inclinedly to the slider 24. The slider 24 is located in the sliding groove 23. A rotating plate 25 is installed on the pressure block 12. A rotating shaft 26 is fixedly connected to the rotating plate 25. A gear is fixedly connected to the rotating shaft 26. A rack is provided on the side of the slider 24. The gear and the rack cooperate so that the slider 24 can slide when the rotating plate 25 rotates. An annular paddle 16 is also provided in the first connecting pipe 4. The inner opening of the annular paddle 16 has an inclined surface. The inclined surface can cooperate with the rotating plate 25, thereby pressing one end of the rotating plate 25 downward, thereby causing the rotating shaft 26 to rotate.

[0033] A retaining ring 17 (which may be fixed by a retaining rod, not shown in the figure) is fixed inside the equipment housing 1. A rotatable roller 18 is installed inside the retaining ring 17. The roller 18 is rotatably mounted on a bracket 19, which is also rotatable. An actuating lever 20 that can move up and down is installed inside the equipment housing 1. The actuating lever 20 has a first rack, and a driven gear is installed on the bracket 19, so that when the actuating lever 20 moves up and down, the bracket 19 can drive the roller 18 accordingly. When the roller 18 rotates, it can press against the fixed block 10 to push the fixed block 10 forward. A first spring 8 is also provided between the pressure block 12 and the second connecting pipe 6. When the bracket 19 is moved, the roller 18 rotates around the bracket 19 and can press against the side of the fixed block 10, pushing the fixed block 10 forward. At this time, the first spring 8 is stretched. When it is pushed to the predetermined position, the rotating surface of the roller 18 separates from the fixed block 10, thereby causing the first spring 8 to reset and pull the pressure block 12.

[0034] The actuating lever 20 is fitted with a second spring 21. A rotatable actuating wheel 22 is provided on one side of the actuating lever 20 near its lower end. A drive gear is mounted on the actuating wheel 22. A second rack is provided on the surface of the actuating lever 20. The drive gear and the second rack cooperate to enable the actuating lever 20 to move up and down. A drive rod is fixed on the axis of the actuating wheel 22. The drive rod extends forward to the front end of the refrigeration mechanism to facilitate user operation of the drive rod.

[0035] A first half-tooth and a second half-tooth are respectively provided on the semi-circular surface of the drive gear. The length of the first half-tooth is less than the length of the second half-tooth, and the first half-tooth and the second half-tooth are not connected to each other.

[0036] When it is necessary to connect the first connecting pipe 4 and the second connecting pipe 6, the user rotates the drive rod. At this time, the first half tooth cooperates with the actuating rod 20, causing the actuating rod 20 to move downward. The downward movement of the actuating rod 20 will cause the bracket 19 to drive the roller 18 to rotate, thereby pushing the fixing block 10 forward. The end of the fixing block 10 presses against the pressure block 12, causing the pressure block 12 to move forward. At this time, the first spring 8 is stretched, the pressure block 12 enters the socket 15, and the end of the support frame 14 can contact the inner wall of the socket 15 and be pressed to undergo elastic bending.

[0037] After the support frame 14 enters the interior of the first connecting pipe 4, the roller 18 separates from the fixing block 10 (at this time, the support frame 14 is not in contact with the lever 16). The first spring 8 provides tension so that the support frame 14 opens along the vertical surface, and the rubber pad 13 is applied to the vertical surface. The pressure block 12 and the support frame 14 can press the rubber pad 13 tightly, thereby ensuring the sealing of the connection between the first connecting pipe 4 and the second connecting pipe 6.

[0038] When it is necessary to disassemble the first connecting pipe 4 and the second connecting pipe 6, the user continues to rotate the drive rod. The second half tooth engages with the toggle lever 20. Since the length of the second half tooth is greater than the length of the first half tooth, the pressure block 12 moves forward a longer distance. During this process, the rotating plate 25 can contact the toggle 16, thereby causing the slider 24 to slide in the sliding groove 23, which in turn causes the support frame 14 to slide inward. Then, when the refrigeration mechanism 5 is pulled outward, the support frame 14 will not contact the inner wall of the socket 15.

[0039] The support frame 14 is installed at an angle and is elastic. When the support frame 14 contacts the inner wall of the socket 15, the force it applies to the slider 24 is inclined, so the slider 24 will not slide at this time.
