Specifically, the transmission assembly includes a motor gear 61, a first gear 62, and a second gear 63. The motor gear 61 is installed on a motor shaft of the motor 1, the second gear 63 is installed on the lock rod 4, the motor gear 61 is meshed with the first gear 62, the first gear 62 is meshed with the second gear 63, the motor gear 61 drives the second gear 63 through the first gear 62, and the lock rod 4 is controlled to rotate in the forward direction or the reverse direction through the transmission effect among the motor gear 61, the first gear 62 and the second gear 63 when the motor 1 works. Meanwhile, the transmission ratio among the motor gear 61, the first gear 62 and the second gear 63 is changed, so that the transmission ratio between the motor 1 and the lock rod 4 can be adjusted, the rotating speed of the lock rod 4 is reduced, and the phenomenon that the lock rod 4 slips off when rotating speed is too high and a knife switch is caused is avoided.
The position of the center of the motor gear 61 in the housing is located by the motor 1, and in order to ensure that the motor gear 61 and the first gear 62, and the first gear 62 and the second gear 63 are always in a meshed state, the positions of the center of the first gear 62 and the center of the second gear 63 in the housing need to be located. In this regard, the transmission assembly of the present embodiment further includes a gear case 64 secured within the housing. The motor gear 61, the first gear 62 and the second gear 63 are all accommodated in the gear box 64, the gear box 64 is provided with a first shaft hole 641 and a second shaft hole 642, a rotating shaft (not shown) is arranged in the middle of the first gear 62, the rotating shaft is inserted in the first shaft hole 641, and the lock rod 4 is inserted in the second shaft hole 642. The first gear 62 is fixed to the rotating shaft, the rotating shaft is located in the first shaft hole 641 along the axial direction and the radial direction of the rotating shaft, and the rotating shaft is driven to rotate in the first shaft hole 641 when the first gear 62 rotates. The lock rod 4 is fixed in the middle of the second gear 63, the lock rod 4 is also positioned at the second shaft hole 642 along the axial direction and the radial direction of the lock rod 4, and the second gear 63 drives the lock rod 4 to rotate at the second shaft hole 642 when rotating. The gear box 64 is matched with the rotating shaft and the lock rod 4 to position the centers of the first gear 62 and the second gear 63 in the shell, and the rotating axis of the lock rod 4 is stabilized, so that the rotating path of the disconnecting link is stabilized, and the stability in closing is ensured. The positioning manner of the rotating shaft and the lock rod 4 in the respective radial and axial directions is the prior art, and the detailed description is omitted in this embodiment.
The switch models in different electric power cabinets are different, and the shapes of the corresponding lock rod 4 and the switch connecting part are different, but if the lock rod 4 is to be replaced, the second gear 63 is required to be detached and replaced together, and the replacing process is very complicated. In order to solve the above problem, the lock lever 4 of the present embodiment includes a connecting shaft 41 and a lock sleeve 42 linked with the knife switch, a second gear 63 is fixed on the connecting shaft 41, the second gear 63 rotates to drive the connecting shaft 41 to rotate, the connecting shaft 41 drives the lock sleeve 42, and the lock sleeve 42 controls the knife switch to rotate. The lock sleeve 42 is disassembled and assembled on the connecting shaft 41, and different lock sleeves 42 are replaced on the connecting shaft 41, so that the knife switch is suitable for different knife switch specifications.
Specifically, be provided with the shaft hole on the lock sleeve 42, even axle 41 rotates and sets up in shaft hole department, sets up on the shaft hole lateral wall along the rotation groove 421 that even axle 41 circumference extends, and even axle 41 outer wall is provided with slip post 411, and slip post 411 slides and sets up in rotation groove 421 department, and the inner wall in shaft hole carries out radial positioning to even axle 41, and the restriction of rotation groove 421 edge to slip post 411 makes even axle 41 along axial positioning on lock sleeve 42. The connecting shaft 41 rotates forwards at the shaft hole to drive the sliding column 411 to slide in the rotating groove 421, and the sliding column 411 can drive the locking sleeve 42 to rotate forwards by pushing the end wall of the rotating groove 421 to control the disconnecting link to close the switch when the sliding column 411 is extruded at the end wall of the rotating groove 421.
The outer wall of the sliding column 411 is provided with an external thread, the outer wall of the connecting shaft 41 is radially provided with an internal thread hole, and the sliding column 411 is in threaded connection with the internal thread hole. When the lock sleeve 42 needs to be replaced, the sliding column 411 is unscrewed, the sliding column 411 leaves from the rotating groove 421, the lock sleeve 42 can be removed from the connecting shaft 41 through axial movement, the opening of the internal threaded hole is aligned and communicated with the rotating groove 421 after the lock sleeve 42 is replaced, and the sliding column 411 is installed at the internal threaded hole again, so that the connecting shaft 41 and the lock sleeve 42 can be prevented from being separated.
The lock sleeve 42 of this embodiment is connected with the switch, can produce a huge traction force to the lock sleeve 42 when the switch-on of switch-on in the twinkling of an eye, drive the further corotation of lock sleeve 42, but motor 1 stall auto-lock this moment, because the extrusion of sliding column 411 is on an end wall of rotating groove 421, leave sufficient space between sliding column 411 and the another end wall of rotating groove 421, consequently, lock sleeve 42 is drawn by the switch and is led into the in-process of further corotation and dodge sliding column 411 through rotating groove 421, avoid connecting shaft 41 and second gear 63 to be drawn by the switch along with lock sleeve 42, thereby avoid the switch-on in the twinkling of an eye motor 1 of shut down state is damaged in further corotation of second gear 63.
