[0017] The protective housing 7 is provided with a cover 29, and the cover 29 is provided with an upper boss 30. The upper boss 30 is provided with an upper through hole 31. The power input assembly 6 includes a power input shaft 32, a radial ball bearing 33, a spacer 34, a thrust bearing 35, and a bearing cover 36. The power input shaft 32 passes through the upper through hole 31 and is rotatably disposed within the upper through hole 31. The power input shaft 32 is provided with an input shaft boss 14, which is located within the upper through hole 31. The thrust bearing 35 is disposed on the upper and lower sides of the input shaft boss 14 within the upper through hole 31. The spacer 34 is sleeved on the power input shaft 32 and is located within the upper through hole 31. The radial ball bearing... The second bearing cover 33 is located between the power input shaft 32 and the upper through hole 31 on the spacer ring 34. The second bearing cover 36 is sleeved on the power input shaft 32. The second bearing cover 36 and the upper through hole 31 are threaded together. The protective housing 7 has a central boss 14. The central boss 14 has a radial ball bearing 37. The power input shaft 32 passes through the central boss 14 and the radial ball bearing 37. The central boss 14 is threaded with a bearing cover 38. The center of the power input gear 1 is limited and fixed by the power input shaft 32 through a key. The power input gear 1 and the power input shaft 32 are fixed by a nut. The power input gear 1 and the power transmission gear 2 mesh.
[0018] The power output shaft 8 is rotatably mounted on the cover 29.
[0019] The power input shaft 32 is powered by an external motor, handwheel, or pneumatic device.
[0020] The bearing cover 2 36 is locked in place by bolts.
[0021] The protective enclosure 7 and the cover 29 are locked together with bolts.
[0022] In practical use, when the power input shaft 32 receives external power, it rotates clockwise, simultaneously driving the lower power input gear 1 to rotate synchronously. This, in turn, drives the power transmission gear 2 to rotate synchronously in the opposite direction counterclockwise. The power transmission gear 2 then drives the power transmission shaft 15 and the cam 18 on the upper part of the shaft to rotate synchronously. The rotating cam 18 drives the transmission rod 21, which is suspended in the guide groove 28, to reciprocate linearly. When the cam 18 drives the transmission rod 21 to move inward linearly, it pushes the second force arm 20 to push the first force arm 19 to rotate inward by 90 degrees, simultaneously driving the power output shaft 8 to rotate by 90 degrees. Because the missing tooth portion of the power transmission gear 2 faces the power output gear 3, when the power transmission gear 2 rotates... When the cam 18 rotates, it does not drive the power output gear 3 to rotate. At this time, the power output gear 3 and the connected valve stem nut 10 are in a stationary state. When the rotating cam 18 pushes the transmission rod 21 to move outward linearly, the transmission rod 21 moves outward linearly, and the second pushing arm 20 pushes the first pushing arm 19 to rotate outward by 90 degrees. At the same time, it drives the power output shaft 8 to rotate by 90 degrees. The toothed part of the power transmission gear 2 begins to mesh with the teeth of the power output gear 3, and drives the power output gear 3 to rotate clockwise in the opposite direction. It also drives the valve stem nut 10 to rotate synchronously. The rotating valve stem nut 10 drives the power output shaft 8 to rotate synchronously. When the power output shaft 8 rotates clockwise, it will move downward under the action of the thread. When the protrusion 23 of the power transmission gear 2 rotates to the stroke adjusting screw 24 and touches it, the gear stops moving. In this way, the power output shaft 8 completes a 90-degree rotation and downward movement. Conversely, when the power input shaft 32 rotates counterclockwise under external force, it drives the power input gear 1 to rotate counterclockwise synchronously. The power input gear 1's counterclockwise rotation drives the power transmission gear 2 to rotate clockwise in the opposite direction. This clockwise rotation of the power transmission half gear drives the valve stem nut 10 to rotate counterclockwise in the opposite direction. The valve stem nut 10's counterclockwise rotation causes the power output shaft 8 to rotate synchronously. During rotation, the power output shaft 8 is lifted upwards due to the force of the thread. When the power output shaft 8 rises to the set height, the teeth of the power transmission gear 2 disengage from the power output gear 3. The power output gear 3 loses power and no longer drives the power output shaft 8 to rotate. Meanwhile, the power transmission shaft 15 continues to rotate under the drive of the power input shaft 32, causing the upper cam 18 to rotate synchronously. The rotating cam 18 carries the transmission rod 21, which is suspended in the guide groove 28, inward in a linear motion. Simultaneously, it carries the connected lever arm 20 and the lever arm 19 connected to lever arm 20 inward in a synchronous motion, causing lever arm 19 to rotate 90 degrees counterclockwise. At this point, the cam 23 of the power transmission half gear contacts the stroke adjustment screw 24. External power input stops, the entire device stops operating, and the set action of raising and rotating the power output shaft 8 by 90 degrees is completed.
