[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0028] Reference Figure 1 to Figure 2 As shown, a centrifuge pushing device of the utility model comprises a housing 1, a top cover 2, a centrifugal chamber 3 and a pushing mechanism 4 for pushing and fixing the centrifugal material;

[0029] The push mechanism 4 includes a threaded rod 41, which is rotatably mounted on the inner bottom wall of the centrifugal chamber 3, and a threaded sleeve 42 is threadedly connected to the outer surface of the threaded rod 41. A rotating groove 421 is provided in the middle of the threaded sleeve 42, and a rotating ring 43 is rotatably mounted on the inner surface of the rotating groove 421. Four push rods 44 are evenly rotatably mounted on the outer surface of the rotating ring 43;

[0030] A fixing mechanism 441 is rotatably mounted on one end of each of the four push rods 44 , and a push plate 46 is rotatably connected to one end of each of the push rods 44 . A limiting component 47 is slidably mounted on one side of the push plate 46 . A discharging mechanism 5 is slidably mounted on the outer surface of the centrifugal chamber 3 .

[0031] The shell 1 and the top cover 2 can be used to seal the centrifugal device to avoid accidental injury to others during operation, thereby protecting the staff. The centrifugal material can be fixed by the push mechanism 4, and the threaded sleeve 42 can be moved up and down by rotating the threaded rod 41. Since the threaded sleeve 42 is designed with a rotating groove 421, the rotating ring 43 can only move up and down when the threaded sleeve 42 rotates, and in the process of its up and down movement, it can drive the push rod 44 to move;

[0032] Furthermore, the push rod can carry the slider 45 to slide on the inner surface of the groove 31, which can make the slider 45 slide more smoothly. During the movement of the slider 45, it will move with the fixing mechanism 441. The limiting component 47 in the fixing mechanism 441 can limit and fix the centrifugal material to keep it stable during the centrifugal process. The discharge mechanism 5 designed by the equipment is controlled by the sliding mechanism 53. After moving the components in the sliding mechanism 53, the restriction on the special-shaped plate 52 is released. Due to the action of the plurality of springs 51, the special-shaped plate 52 and the centrifugal material on the special-shaped plate 52 can be pushed up, making it easier for the staff to take it out.

[0033] Reference Figure 3 As shown, in one embodiment of the present utility model, four grooves 31 are evenly formed on the bottom wall of the inner surface of the centrifugal chamber 3 .

[0034] The four grooves 31 can make the slider 45 slide more stably on its inner surface and increase the stability of the assembly during centrifugation.

[0035] Reference Figure 3 As shown, in one embodiment of the utility model, the fixing mechanism 441 includes a slider 45, the slider 45 is slidably installed on the inner surface of the groove 31, one end of the push rod 44 is rotatably installed on the upper end of the slider 45, and one side of the push plate 46 is evenly slidably installed with a plurality of limit assemblies 47.

[0036] One side of the slider 45 is connected to a push plate 46. When the threaded rod 41 is rotated, the push rod 44 will push or pull the slider 45. At this time, the slider 45 can also move with the push plate 46. During the movement, the centrifugal material can be fixed and loosened.

[0037] Reference Figure 4 As shown, in one embodiment of the utility model, the limiting assembly 47 includes a spring sleeve 471, a spring 472 is arranged inside the spring sleeve 471, one end of the spring 472 is fixedly connected to one side of the inner surface of the push plate 46, and the other end of the spring 472 is fixedly connected to a telescopic rod 473, and the telescopic rod 473 is slidably installed on the inner surface of the spring sleeve 471.

[0038] The push plate 46 is a hollow structure, and a spring sleeve 471 is installed inside the hollow push plate 46. A spring 472 is installed in the spring sleeve 471. One end of the spring 472 is fixedly connected to a telescopic rod 473. The telescopic rod 473 is slidably installed on the inner surface of the spring sleeve 471. When the push plate 46 moves toward the centrifugal chamber 3, the centrifugal material has been placed on the special-shaped plate 52. The special-shaped plate 52 and the bottom wall of the centrifugal chamber 3 are in a horizontal state. In the process of several telescopic rods 473 contacting the centrifugal material, the centrifugal material is first pushed. According to different contact times, the telescopic rods 473 will be in different elongation states, and the centrifugal material is wrapped and fixed in all directions.

[0039] Reference Figure 5 As shown, in one embodiment of the utility model, a groove 2 32 is provided on the bottom wall of the inner surface of the centrifugal chamber 3, and a plurality of springs 2 51 are evenly and fixedly installed on the inner surface of the groove 2 32. A special-shaped plate 52 is slidably installed on the inner surface of the centrifugal chamber 3, and the lower end of the special-shaped plate 52 is slidably installed on the inner surface of the groove 2 32, and the upper ends of the plurality of springs 2 51 are fixedly connected to the lower end of the special-shaped plate 52.

[0040] When the bottom of the special-shaped plate 52 is at the same horizontal plane as the bottom wall of the centrifugal chamber 3 , the second spring 51 is in a compressed state, and the bottom of the special-shaped plate 52 slides on the inner surface of the second groove 32 .

[0041] Reference Figure 6 As shown, in one embodiment of the utility model, the outer surface of the centrifugal chamber 3 is provided with a groove three 33, the inner surface of the groove three 33 is provided with a groove four 331, the outer surface of the special-shaped plate 52 is provided with a groove five 521, the outer surface of the centrifugal chamber 3 is fixedly installed with a sliding mechanism 53, the sliding mechanism 53 includes a slide bar 56, the slide bar 56 is fixedly installed on the outer surface of the centrifugal chamber 3, the outer surface of the slide bar 56 is wrapped with a spring three 55, the outer surface of the slide bar 56 is slidably installed with an L-shaped plate 54, the L-shaped plate 54 is fixedly connected to one side of the spring three 55, and the upper part of the L-shaped plate 54 is slidably installed on the inner surfaces of the groove three 33, the groove four 331 and the groove five 521.

[0042] Before centrifugation, the upper part of the L-shaped plate 54 is slidably installed on the inner surface of the groove four 331 to fix the L-shaped plate 54. After centrifugation is completed, the L-shaped plate 54 is pulled outward to disengage from the groove four 331 and slide on the inner surface of the groove five 521. At this time, under the action of the spring two 51, the L-shaped plate 54 will bounce upward to achieve the purpose of pushing out the centrifuged raw materials.

[0043] Working principle: first, place the centrifugal raw material at the bottom of the special-shaped plate 52, rotate the threaded rod 41 to push the slider 45 to slide on the inner surface of the groove 31 through the push rod 44, and then the push plate 46 slides. After the telescopic rod 473 contacts the centrifugal raw material, the spring 472 can fix the centrifugal raw material to facilitate the next step of centrifugation.

[0044] After centrifugation is completed, the L-shaped plate 54 is pulled outward to separate the L-shaped plate 54 from the groove four 331 and the groove five 521. At this time, due to the action of the spring two 51, the special-shaped plate 52 will be lifted up, and the centrifuged raw materials will be pushed to a position convenient for the staff to take out. At this time, the spring three 55 pulls the L-shaped plate 54. Similarly, when it is necessary to fix the special-shaped plate 52 at its bottom and make it level with the bottom wall of the centrifugal chamber 3, the spring three 55 pulls the L-shaped plate 54 to prevent it from being thrown away under the joint action of the spring two 51 and the centrifuge, and losing control will cause damage to the device and affect the centrifugation result.

[0045] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention of the utility model.
