In accordance with the operation requirement, the operation action should not be directly transmitted to the motor portion in the manual operation, and therefore, the switching operation needs to be performed by the switching device.
CN201725721U discloses a three-position switch manual and electric operation switching device. The device comprises a main shaft, wherein the front end of the main shaft is a rotary output end, and the rear end of the main shaft is a manual operation end; an interlocking shaft is inserted into a central hole of the main shaft, and a pressure spring is arranged between the front end of the interlocking shaft and the front end of the central hole; the rear section of the main shaft is also provided with a radially through sliding groove, the interlocking shaft is provided with a radially through pin hole, a bayonet lock penetrates through the pin hole, and two ends of the bayonet lock penetrate through the sliding groove on the main shaft and extend out of the main shaft; an electric driving wheel which can be matched with the motor and the driving mechanism for driving is sleeved on the periphery of the spindle behind the clamping pin in an empty mode, a radial clamping groove is formed in the front end face of the electric driving wheel, and the clamping pin can be clamped in the clamping groove when the interlocking shaft moves backwards. The switching device controls the transmission of the braking force through a clamping pin. In manual switching, particularly in high-speed operation of the drive wheel, there is a risk of directly pushing the bayonet lock which rotates therewith.
The utility model discloses there is complicated structure, manufacturing difficulty and installation inconvenience to current all kinds of auto-change over device, has had defects such as dangerous difference to make the improvement moreover.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure is reliable, simple to operate, switching and transmission safe and reliable's manual and electrically-operated auto-change over device of three station switches.
The manual and electric operation switching device of the three-station switch comprises a fixed operation panel, wherein a rotating shaft, an interlocking plate and a baffle plate are arranged on the operation panel, a connecting block, a gear plate and a handle are sequentially arranged on the rotating shaft in a sleeved mode, a bending part of the operation panel is provided with a notch, the interlocking plate vertically penetrates through the notch, a pressure spring is arranged at the upper end of the interlocking plate, and the position of the interlocking plate is limited by an elastic pin; and a microswitch connected with a motor is arranged at the bottom of the interlocking plate, and when the compression spring is compressed to enable the interlocking plate to move downwards, the microswitch is triggered.
Specifically, the baffle has a sector that intermeshes with the gear plate.
Specifically, the operation panel is further provided with an operation handle insertion hole, and the baffle plate shields the operation handle insertion hole in a state that the operation panel is not manually operated.
The utility model discloses simple structure, manufacturing convenience can directly throw off electric drive wheel during manual operation, need not extra operation, switch and simple and convenient, safe and reliable of transmission.
Drawings
Fig. 1 and fig. 1 are schematic structural views of the present invention.
Fig. 2 is a schematic view of the internal structure of the utility model during manual operation.
Detailed Description
In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.
As shown in fig. 1, the utility model provides a manual and electric operation auto-change over device of three-position switch, it includes a fixed operating panel 1, and one side portion of this operating panel 1 has the portion of bending perpendicular this operating panel 1, and this portion of bending forms a plurality of notches.
Perpendicular to this operating panel 1 on install pivot 6, this pivot 6 is gone up the installation cover in proper order and is equipped with connecting block 7, gear plate 5, handle 2. The other end of the connecting block 7 is connected to an interlocking plate 8. Interlocking plate 8 passes vertically through the notch at the panel bend and can move up and down along the notch. The top end of the interlocking plate 8 is provided with a central hole, an elastic pin 10 is inserted in the central hole, a pressure spring 9 is arranged at the bending part at the top end of the panel and the bottom end of the central hole of the interlocking plate, namely the pressure spring 9 is sleeved on the interlocking plate 8, and two ends of the pressure spring respectively abut against the notch and the elastic pin 10. The bottom of the interlocking plate is provided with a microswitch 4 connected with an electric motor. The operation panel 1 is also provided with an operation handle insertion hole. The shutter 3 is rotatably mounted on the operation panel 1. The baffle 3 has a sector at one end which intermeshes with the gear plate 5. In a state where the manual operation is not performed, the other end of the shutter 3 blocks the operation handle insertion hole.
As shown in fig. 2, when manually operated, the handle 2 is rotated counterclockwise, and the gear plate 5 and the connecting block 7 on the rotating shaft 6 are rotated in synchronization. The gear plate 5 drives the engaged baffle 3 to rotate, and the operating handle insertion hole shielded by the baffle is exposed; meanwhile, the connecting block 7 drives the interlocking plate 8 to move downwards until the micro switch 4 is touched, so that a winding loop inside the motor is cut off, and torque is not transmitted. At this time, the operating handle is inserted, and the pressure spring 9 is always kept in a compressed state; when the manual operation is finished and the operating handle is pulled out, interlocking plate 8 and shutter 3 are synchronously returned to the initial position by the action of compression spring 9. At the moment, the microswitch 4 is automatically closed, the internal circuit of the motor is switched on, and the motor can be electrically operated.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
