Technical field
The present invention relates to double power supply converting switch manufacturing technology field, especially a kind of hand of control Twin-power swich
Motivation structure.
Background technology
Double power supply converting switch is a kind of while connecting two-way power supply, the electrical equipment that can be switched between two-way power supply
Part.Existing double power supply converting switch would generally set manual switching mechanism and mechanism for automatically switching, when power supply occurs all the way
After failure, double power supply converting switch can be by manual switching mechanism and mechanism for automatically switching electricity consumption loop switch to another road
On power supply.
Its manual switching mechanism of existing double power supply converting switch has been required for a drive shaft, a handle, by driving
Moving axis, which is rotated, drives execution unit to carry out power supply switching, and the drive end of drive shaft must be exposed to double power supply converting switch face-piece
Outside, drive shaft turns are driven with the drive end for facilitating handle to connect drive shaft.But this traditional manual switching machine
Structure is primarily present following problem, and one is that handle is separated with double power supply converting switch body, is easily lost；Two be handle connection
There are two rotation directions after the drive end of drive shaft, when rotation direction error, be easily damaged handle or drive shaft；The two
Problem finally have impact on the promptness and reliability of double power supply converting switch switching action；Three be drive shaft drive end it is exposed,
Easily snapped into by foreign matter entrance or by foreign object, snapped into if any foreign matter entrance or by foreign object and be easy for hindering drive shaft motion, also can
Influence the promptness and reliability of double power supply converting switch handover operation.
Another convenience, because existing double power supply converting switch sets manual switching mechanism and mechanism for automatically switching simultaneously,
Easily there is manual switching mechanism and mechanism for automatically switching and interfered with each other while acting, there can be potential safety hazard in use.

On axle 71；When the other end of connecting rod 6 and the second hinging pin shaft 71 of diverse location are hinged, direction is stirred in handle 2 constant
In the case of can change the rotation direction of drive shaft 4, can also change the rotational angle of drive shaft 4 and rotation dynamics certainly.
The face-piece 3, provided with slot to make way 32 is stirred, handle 2 is stirred to facilitate in the end close to the struck side 22 of handle 2.
An arc notch 212, two medial surfaces difference energy of arc notch 212 are additionally provided with the drive end 21 of handle 2
It is engaged to limit the rotational angle of the handle 2 in both rotational directions with the upper and lower sides of the spacing preiection 13.
In order to prevent the man-operated mechanism and automechanism of Twin-power swich from interfering action, the present embodiment is described
The one displaceable microswitch 9 of toggle 8 and one is housed, microswitch 9 is used to control the logical of mechanism for automatically switching power supply on support 1
Disconnected, the limitation handle 2 is rotated and makes microswitch 9 in an ON state before toggle 8 is shifted, and now handle 2 can not be operated, micro-
Dynamic switch 9 makes the power on of mechanism for automatically switching, and mechanism for automatically switching is actionable to carry out power supply switching；Toggle 8 is solved after shifting
Except the rotation to the handle 2 is limited and is off microswitch 9, now handle 2 is operable, and man-operated mechanism is with regard to energy
Action carries out power supply switching, and microswitch 9 is off making the power supply of mechanism for automatically switching to disconnect, and mechanism for automatically switching is not
Can action.The man-operated mechanism and mechanism for automatically switching of twin-power switch are realized by the control action of toggle 8 and microswitch 9
Interlocking.
The specific fit structure of toggle 8 and microswitch 9 and handle 2 is that a spacing hole 24 is provided with the handle 2,
The spacing hole 24 is on the struck side 22 of handle 2, and toggle 8 is provided with clicking section 81, limiting section 82 and top splenium 83, described group
Dynamic portion 81 stretches out that the face-piece 3 is outer to be stirred toggle 8 with hand and shift to facilitate, and the limiting section 82 can match with the spacing hole 24
Close, the top splenium 83 can be engaged with the contact of the microswitch 9, and the limiting section 82 coordinates on the spacing hole 24
When, the top splenium 83 departs from the contact of the microswitch 9, when the limiting section 82 departs from the spacing hole 24, the top
Splenium 83 withstands the contact of the microswitch 9.
Also be connected a bearing 10 on the support 1, and bearing 10 is provided with track 101, and the toggle 8 coordinates in bearing 10
It can move back and forth on track 101 along track 101, the microswitch 9 is connected on bearing 10.
The bearing 10 is additionally provided with a stretching face-piece 3 provided with a fixed lobe 102 stretched out outside face-piece 3, the toggle 8
Outer fixed part 84, the fixed part 84 is provided with mutual corresponding padlock through hole 841,1021 with the fixed lobe 102.So
It is engaged by padlock with the fixed part 84 with the fixed lobe 102 mutually corresponding padlock through hole 841,1021, with regard to energy
Prevent the personnel of no operating right from arbitrarily stirring toggle 8.
The operating process of the present embodiment is：When needing manual switching twin-power switch, toggle 8 is stirred with hand along along bearing 10
Track 101 shift, the limiting section 82 on toggle 8 is departed from the spacing hole 24, handle 2 be unlocked, Ran Housuo
The contact that top splenium 83 withstands the microswitch 9 is stated, microswitch 9 cuts off the power supply of mechanism for automatically switching, automatic switching machine
Structure akinesia, now carrying handle 2 rotate counterclockwise handle 2, as shown in Figure 8；After handle 2 is rotated, the drive end of handle 2
The first hinging pin shaft 23 on 21 first moves touching connecting rod 6 after a small distance along the strip hole 61 on connecting rod 6 and moved, connecting rod 6
Drive crank 7 and drive shaft 4 to rotate together by the second hinging pin shaft 71 again, realize manual switching；If now connecting rod 6 is another
When one end is hinged with another second hinging pin shaft 71 on crank 7, crank 7 and drive shaft 4 will be rotated in another direction, with more
The demand of different executing agencies is adapted to well.
After manual switching, handle 2 is decontroled, arc lacks handle 2 on self-return, the drive end 21 of handle 2 under the effect of torsion spring 5
One medial surface of mouth 212 rests against the upside of the spacing preiection 13；The return of toggle 8, the limiting section can be now stirred again
82 with regard to when cooperation is on the spacing hole 24 again, preventing from stirring handle 2 again, and the top splenium 83 just departs from the microswitch
9 contact, microswitch 9 connect mechanism for automatically switching power supply, act mechanism for automatically switching, realize man-operated mechanism and
Mechanism for automatically switching is interlocked.
It the above is only a preferred embodiment of the invention, those skilled in the art is made equivalent change by claim
Both fall within the protection domain of this case.
