Description
Technical field
The present invention relates to automatic change-over field, more particularly to a kind of manual-operating mechanism of automatic change-over.
Background technology
Automatic change-over is a kind of electrical equipment that can be switched between two-way power supply, and it is usually provided with manual behaviour
Make mechanism and mechanism for automatically switching, can manually operating mechanism or mechanism for automatically switching after power supply all the way breaks down
On electricity consumption loop switch to another way power supply.The manual-operating mechanism of the automatic change-over of prior art generally comprises handle
And drive shaft, drive shaft turns are driven by handle, to control automatic change-over to close a floodgate.After the completion of combined floodgate, it is necessary to remove hand
Handle, otherwise handle can be interfered with product component, influence the action under product auto state.Therefore, prior art is most
To be separately configured, handle separates the handle of number automatic change-over with product.This way easily causes handle to be lost, and handle is lost
After mistake automatic change-over will be caused not to be operated manually.At present, small part automatic change-over also connects handle
On product, although this way solves the problems, such as that handle is provided separately with product and is easily lost, but it is more multiple structure to be present
It is miscellaneous, operation it is not laborsaving the problem of.
The content of the invention
The invention provides a kind of manual-operating mechanism of automatic change-over, the automatic conversion of prior art is which overcomed

In the present embodiment, face-piece 10 is provided with outside the support 1, the drive shaft 3, connecting rod 4, driving member 5 are located at face-piece
10 inner sides, face-piece 10, which is provided with, to be made the other end of handle 2 exposed and is available for the bit architecture that allows that handle 2 freely comes in and goes out.This allows bit architecture
Specifically include and be arranged on the strip hole 101 at the top of cover along the length direction of face-piece 10 and lead to the side of the strip hole 101
Resigning breach 102, the resigning breach 102 make the other end of handle 2 exposed, and strip hole 101 makes handle 2 freely to come in and go out face-piece
10, as shown in Figure 7, Figure 8.
In the present embodiment, in order to prevent automatic change-over influencing each other under manual mode and auto state, this hair
It is bright that a moveable toggle 7 and an automatic switching machine for being used to control automatic change-over are installed on the support 1
The microswitch 8 whether structure starts.Toggle 7 has two operating positions, when toggle 7 is moved to the first operating position, described in limitation
Handle 2 rotates and makes microswitch 8 in an ON state, and now, handle 2 can not operate, and microswitch 8 makes mechanism for automatically switching
Control circuit conducting, mechanism for automatically switching it is actionable carry out power supply switching；When toggle 7 is moved backward to the second operating position,
Release the rotation to the handle 2 to limit and be off microswitch 8, now, handle 2 is operable, automatically switches
The control circuit of mechanism disconnects, mechanism for automatically switching akinesia.Realized certainly by the control action of toggle 7 and microswitch 8
The interlocking of the manual-operating mechanism and mechanism for automatically switching of dynamic change-over switch.
The fit structure of toggle 7 and handle 2, microswitch 8 is specific as follows：The other end of handle 2 is provided with a spacing hole 23,
The toggle 7 is provided with clicking section 71, limiting section 72 and top splenium 73, and when the toggle 7 is moved to the first operating position, its is spacing
Portion 72 inserts the spacing hole 23 of handle 2, and its top splenium 73 departs from the drive division 81 of microswitch 8, connects microswitch 8；Institute
When stating toggle 7 and being moved to the second operating position, its limiting section 72 exits the spacing hole 23 of handle 2, its top pressure fine motion of top splenium 73
The drive division 81 of switch 8, disconnects microswitch 8.
In the present embodiment, the specific fit structure of the microswitch 8 and support 1 is as follows：One bearing is installed on support 1
9, the bearing 9 is provided with sliding rail, and the toggle 7 is snug fit at the sliding rail.The microswitch 8 is fixed on bearing
On 9.The toggle 7, microswitch 8, bearing 9 are located in the face-piece 10, and face-piece 10 is provided with stirring for toggle 7
The strip resigning through hole 103 and a limiting section 72 for toggle 7 that portion 71 is stretched out pass in and out and lead to the side of the strip hole 101
Through hole 104.The bearing 9 is provided with the fixed part 91 outside the resigning through hole of a stretching face-piece 10, and the fixed part 91 is provided with
One positioning hole 911, a positioning hole 711 is also opened up on the clicking section 71 of the toggle 7, when toggle 7 is moved to the first working position
When putting, the positioning hole 711 of its clicking section 71 and the positioning hole 911 of fixed part 91 are relative, as shown in figure 9, now, can use padlock
Two positioning holes 711,911 are locked together, the state for making toggle 7 keep limitation handle 2 to rotate, avoid handle 2 from being misused.When
When toggle 7 is reversely moved to the second operating position, the positioning hole 711 of its clicking section 71 and the positioning hole 911 of fixed part 91 stagger, such as
Shown in Figure 10.
The operating process of the present invention is as follows：When needing manually operated automatic change-over, the clicking section of toggle 7 is first stirred
71, promote toggle 7 to be moved to the second operating position, the limiting section 72 on toggle 7 is departed from the spacing hole 23 of handle 2, to handle 2
It is unlocked, also, the drive division 81 of the top pressure microswitch 8 of top splenium 73 of toggle 7, the cut-out of microswitch 8 is automatically switched
The control circuit of mechanism, mechanism for automatically switching akinesia.Then, the other end of upward carrying handle 2, handle 2 is made along the inverse time
Pin direction rotates, when handle 2 is rotated counterclockwise to when making the convex portion 22 of its one end be against on the first bumping post 43 of connecting rod 4, handle 2
On the direction of the other end extended line of connecting rod 4, as shown in Figure 5.When continuing rotational handle 2 in the counterclockwise direction, the meeting of handle 2
Drivening rod 4 rotates in the counterclockwise direction in the lump around the axis of drive shaft 3, and compresses torsion spring 6.Connecting rod 4 rotates a low-angle
Afterwards, the second bumping post 44 thereon arrives to driving member 5, and as handle 2 is rotated further, connecting rod 4 will promote driving member 5 and then to rotate,
Because driving member 5 is coaxial with drive shaft 3 and is fixedly connected, thus, drive shaft 3 also and then rotates, as shown in fig. 6, so as to realize
Manual switching power supply.In the rotation process of 2 drivening rod of handle 4, handle 2 and connecting rod 4 are combined equivalent to a root long bar, thus people
The power arm that hand is applied to corresponding to the driving force of handle 2 is most long, and operation is very laborsaving.
After the completion of manually operated, handle 2 is decontroled, connecting rod 4 is under the restoring force effect of torsion spring 6 with connecting rod 4 along clockwise
Rotate, until connecting rod 4 touches on support 1 rotation prevention portion 11 set；After handle 2 rotates clockwise in place with connecting rod 4, handle 2 leans on
Deadweight is rotated further to the state being returned to as shown in Figure 1, Figure 7 shows.Now, toggle 7 can be stirred again, make the limiting section 72 of toggle 7
Insert in the spacing hole 23 of the other end of handle 2, prevent from stirring handle 2 again, the top splenium 73 of toggle 7 then departs from microswitch 8
Drive division 81, connect microswitch 8, mechanism for automatically switching is actionable.
Above-described embodiment is only used for further illustrating a kind of manual-operating mechanism of automatic change-over of the present invention, but this
Invent and be not limited to embodiment, every any simple modification made according to technical spirit of the invention to above example,
Equivalent variations and modification, each fall within the protection domain of technical solution of the present invention.
