In addition, the technical features involved in different embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] In the description of the utility model, it needs to be explained that the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0027] In the description of the utility model, it needs to be explained that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be locking connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can be directly connected, or indirectly connected through an intermediate medium, it can be the communication inside two elements. For the ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0028] As shown in Figures 1-3 The embodiment of the utility model provides a positionable centrifuge, which comprises a box body, a centrifugal cylinder arranged in the box body and a rotating mechanism connected with the centrifugal cylinder. Wherein, the rotating mechanism comprises a rotating shaft assembly 1 connected with the centrifugal cylinder, a driving motor (not shown in the figure) in transmission connection with the rotating shaft assembly, and a control disc 2 sleeved on the rotating shaft assembly 1 and synchronously rotating with the rotating shaft assembly 1. At the same time, the centrifuge further comprises a control assembly, which is used for controlling the phase angle after the centrifugal cylinder stops, so that the centrifugal cylinder can be locked at the specified phase angle position, and the operator can operate in the centrifugal cylinder conveniently.

[0029] In the embodiment, the control assembly comprises a mounting base 3, a control block 4, and a telescopic mechanism arranged on the mounting base 3. The mounting base 3 is provided with a guide rail 5, and the telescopic mechanism comprises a telescopic base 6 and a telescopic driving part. The telescopic driving part is fixedly connected with the mounting base 3, and the telescopic base 6 is slidably connected with the guide rail 5 and connected with a telescopic end of the telescopic driving part. The control block 4 is connected with the telescopic base 6, so that the control block 4 and the telescopic base 6 can slide along the guide rail 5 and move towards or away from the control disc 2 under the action of the telescopic end of the telescopic driving part.

[0030] The control disc 2 is provided with one or more control grooves 7, which are matched with the end of the control block 4, so that the end of the control block 4 can stably limit the rotation shaft assembly 1 when inserted into the control groove 7. It can be understood that when the control groove 7 is provided with only one, the centrifugal cylinder has only one phase angle that can be locked, and when the control groove 7 is provided with multiple, the centrifugal cylinder has multiple phase angles that can be locked.

[0031] In a specific embodiment of the embodiment, the control groove 7 and the end of the control block 4 are both wedge-shaped, so that the control block 4 can be better inserted into the control groove 7 to form a limit, avoiding the difficulty of accurately inserting the control block 4 into the control groove 7 during the slow rotation of the centrifugal cylinder.

[0032] At the same time, as shown in Figure 4 As a preferred embodiment, the control block 4 and the telescopic base 6 are connected in a movable manner to a certain extent in the embodiment, and a spring 8 is arranged in the telescopic base 6 and connected with the control block 4. Specifically, the telescopic base 6 is provided with a waist-shaped groove, and the bolt connecting the control block 4 with the telescopic base 6 is inserted into the waist-shaped groove and connected with the spring 8. Therefore, when the control block 4 moves towards the control disc 2 under the driving of the telescopic driving part, since the control disc 2 may still have a slow rotation speed, the control groove 7 cannot be aligned with the control block 4, and when the control block 4 contacts the side wall of the control disc 2, the control block 4 will move backward relative to the telescopic base 6 during the forward movement of the telescopic base 6, and the spring 8 will be compressed to a certain extent. When the control groove 7 is rotated to be aligned with the control block 4, the spring 8 works to further push the control block 4 out, so that the end of the control block 4 is inserted into the control groove 7. This way can not only accurately stop and limit the control disc 2, but also avoid the hard collision between the control block 4 and the control disc 2.

[0033] In the embodiment, the telescopic driving part comprises a telescopic cylinder 9 and a connecting rod 10. The telescopic cylinder 9 is fixedly connected with the mounting base 3, one end of the connecting rod 10 is connected with the telescopic rod of the telescopic cylinder 9, and the other end is connected with the telescopic base 6, so that the telescopic base 6 can be driven to advance or retreat when the telescopic rod of the telescopic cylinder 9 is telescoped. As a preferred embodiment, the mounting base 3 is further provided with a stop block 11 in the embodiment, the stop block 11 corresponds to the end of the telescopic rod of the telescopic cylinder 9, and when the telescopic rod is extended to the limit position, the stop block 11 can stop the telescopic rod, so as to avoid that the control block 4 is excessively advanced to impact the control disc 2. Correspondingly, the connecting rod 10 is connected at the center position of the telescopic rod.

[0034] Please refer to Figure 3 As a preferred embodiment, the mounting base 3 is further provided with two groups of photoelectric switches 12 in the embodiment, and the telescopic base 6 is connected with a detection plate 13. When the telescopic base 6 moves to different positions, the corresponding photoelectric switch 12 can detect the telescopic base 6, so that the system can confirm the position of the telescopic base 6, that is, the control block 4, and determine whether the control disc 2 is in the limiting state or the free rotation state, so as to facilitate subsequent operation.

[0035] As described above, the positionable centrifugal machine provided by the embodiment can limit and lock the rotating shaft assembly 1 of the centrifugal cylinder through the control assembly, so that the centrifugal cylinder is fixed at a preset phase angle, the operator can operate in the centrifugal cylinder, and the applicability and operation convenience of the centrifugal machine are improved.

[0036] The technical features of the above embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the description.

[0037] The above embodiments only express several implementation manners of the application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the application. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the application, and these all belong to the protection scope of the application. Therefore, the protection scope of the application should be subject to the appended claims.
