Detailed Description
The technical scheme of the invention is further described below with reference to the accompanying drawings.
Referring to fig. 1-3, a rotary lifting mechanism is provided in the sealed cavity.
The rotary lifting mechanism comprises a first cylindrical body 1 fixedly arranged in a sealing cavity and a second cylindrical body 2 which is sleeved on the outer peripheral part of the first cylindrical body 1 and rotates around the axial lead direction of the rotary lifting mechanism. In the present embodiment, the first cylindrical body 1 and the second cylindrical body 2 are coaxially distributed, and the axial line direction of the first cylindrical body 1 is distributed in the vertical direction.
The rotary lifting mechanism further comprises three guide grooves 3 which are distributed along the vertical direction and uniformly arranged on the first cylindrical body 1 at intervals, and the three guide grooves 3 form an included angle of 120 degrees.
The rotary lifting mechanism further comprises three driving grooves 4 which are obliquely distributed along the same direction and uniformly arranged on the second cylinder 2 at intervals, and the driving grooves 4 are in one-to-one correspondence with the guide grooves 3. The inclination angle of the driving groove 4 is adjusted according to the speed required for lifting the lifting member 5, and when the required speed is higher, the length extension direction of the driving groove 4 is closer to the vertical direction, namely, the direction of the guide groove 3; the smaller the required speed, the closer the longitudinal extension direction of the driving groove 4 is to the horizontal direction. Obviously, the driving groove 4 forms an angle between 0 and 90 degrees with the vertical direction, and does not comprise two end point angles.
The outer peripheral part of the second cylinder body 2 is uniformly provided with a plurality of stirring grooves 9 which are distributed along the vertical direction and used for being stirred by the manipulator in a ring at intervals.
The rotary lifting mechanism further comprises a lifting piece 5 arranged in the first cylindrical body 1, three sliding pieces 6 which are uniformly spaced and fixedly arranged on the lifting piece 5 in a ring mode, and each sliding piece 6 is inserted into one guide groove 3 and the corresponding driving groove 4. The sliding piece 6 is lifted in the guide groove 3 by the driving of the driving groove 4, namely the lifting piece 5 is lifted in the sealing cavity. In the present embodiment, the sliding members 6 are distributed in the radial direction of the first cylindrical body 1, i.e., in the horizontal direction in the first cylindrical body 1.
The driving groove 4 includes an inclined groove 7, and horizontal grooves 8 communicating with both ends of the inclined groove 7. In the present embodiment, each driving groove 4 includes two inclined grooves 7, three horizontal grooves 8 communicating at both ends of the two inclined grooves 7.
By arranging the horizontal grooves 8, the lifting piece 5 can be provided with a plurality of lifting stations during lifting, and when the sliding piece 6 enters different horizontal grooves 8, the corresponding lifting piece 5 is positioned on different lifting stations; meanwhile, the manipulator cannot be shifted in place once, and the sectional movement of the lifting piece 5 is realized by arranging a plurality of horizontal grooves 8.
The sealed cavity is provided with a lifted piece 10, the lifted piece 10 is provided with a protruding part 11 extending downwards, and the lifted piece 5 is provided with a groove part 12 for being matched with the protruding part 11 in a clamping way. By this arrangement, the lifted member 10 can be prevented from moving relative to the lifting member 5 in the lifting process, so that the lifted member 10 can be stably lifted in the sealed cavity.
The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and to implement the same, but are not intended to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
