Description
Technical field
The invention belongs to Design of Mechanical Structure technical field, be specifically related to a kind of interlock.
Background technology
Accident power network equipment is the power distribution equipment being specifically designed to accident distribution network, and the controller switching equipment for changing between normal power source and emergency power supply.When shipowner's electrical network local is damaged, forms bridge circuit by accident power network and accident power network equipment etc., the electric energy that generator sends directly is fed to accident power grid user.Through reasonable disposition, the working power of load equipment can obtain from arbitrary the generator in arbitrary power station flexibly, easily, drastically increases the vitality of ship electric power system.Mechanical interlock mechanism is for guaranteeing when operating emergent connecting box: when plug and socket does not reliably dock, the mains switch of emergent connecting box can not close; When plug, socket carry out plug operation, the mains switch of emergent connecting box must disconnect.
Summary of the invention
The object of the invention is: design a mechanism interlocking in connecting box met an urgent need by socket, thus ensure that the plug in emergent connecting box can dock and disconnect reliably with socket;
Technical scheme of the present invention is: a kind of mechanical interlocking of receptacle accepts box, and it comprises: bent axle, driving gear set, installing rack, connecting plate, slide plate, pressing plate, back-moving spring and receptacle accepts box;
Comprise in receptacle accepts box: housing and be arranged on socket and the switch of enclosure interior; The inner peripheral surface of socket is provided with groove vertically together, for matching with the plug that head is provided with horizontal convex edge; Switch is realized the closed of contact by the gate rotating himself and is disconnected;
The top of bent axle is connected with outer handle, and the stage casing of bent axle is provided with position limiting structure;
Driving gear set comprises two intermeshing travelling gears;
Slide plate one side end face is provided with snap fit;
Pressing plate is provided with former and later two bar holes thereon;
Integrated connection closes: the bar hole passing connecting plate and pressing plate rear portion after the top of bent axle is connected with outer handle successively, and being socketed in one of them driving gearshaft of driving gear set, the position limiting structure in bent axle stage casing is arranged in the bar hole at pressing plate rear portion; Another driving gearshaft of driving gear set is connected with the connecting bushing of switch gate; One end of pressing plate is fixedly installed in installing rack, and the other end is positioned at the below of the vertical groove of socket circumference; One end of slide plate is connected with connecting plate, and the other end is between pressing plate and socket, and the snap fit of slide plate is positioned on the right side of pressing plate front portion; Pillar in installing rack is through the bar hole of pressing plate front portion, and back-moving spring is socketed on pillar, and back-moving spring is that pressing plate provides support and restoring force.
When the state that plug does not insert, the position limiting structure in bent axle stage casing is arranged in the bar hole at pressing plate rear portion, and the snap fit of the front portion blocks slide plate of pressing plate, therefore cannot rotary crankshaft, namely cannot drive the combined floodgate that driving gear set is carried out switch;
When the state that plug inserts, in plug access socket, the convex edge of pin head arranges vertical groove from socket circumference and passes, downward extruding pressing plate, the snap fit of slide plate is made to depart from the front portion of pressing plate and the bar hole at the position limiting structure of bent axle disengaging pressing plate rear portion, now rotary crankshaft, connecting plate and driving gear set are rotated with the rotation of bent axle, can realize the combined floodgate driving driving gear set to carry out switch; After the combined floodgate of switch, slide plate is driven by connecting plate and produces displacement, and its snap fit moves to above the convex edge of pin head, and plug cannot be extracted.
The invention has the beneficial effects as follows: (1) component part of the present invention is simple, machining accuracy is low, assembling is simple, well meets mechanical interlock mechanism designing requirement;
(2) the present invention adopts the version of dual interlock; Wherein, a mechanical interlocking structure adopts centered by bent axle, connecting plate can be driven to rotate, then drive slide plate by connecting plate, carry out switching movements after rotary crankshaft; Another mechanical interlocking structure is the convex edge of plug end, and plug can not be extracted when the switch is closed, and when plug does not insert, switch can not close, and ensures the function of mechanical interlocking.

Embodiment
See accompanying drawing 1, a kind of mechanical interlocking of receptacle accepts box, it comprises: bent axle 2, driving gear set 3, installing rack 4, connecting plate 5, slide plate 6, pressing plate 7, back-moving spring 8 and receptacle accepts box 9;
Comprise in receptacle accepts box 9: housing 9-1 and be arranged on socket 9-2 and the switch 9-3 of enclosure interior; The inner peripheral surface of socket 9-2 is provided with groove vertically together, for matching with the plug that head is provided with horizontal convex edge; Switch 9-3 is realized the closed of contact by the gate rotating himself and is disconnected;
The top of bent axle 2 is connected with outer handle, and the stage casing of bent axle 2 is provided with position limiting structure 2-1;
Driving gear set 3 comprises two intermeshing travelling gears;
Slide plate 6 one side end face is provided with snap fit;
Pressing plate 7 is provided with former and later two bar holes thereon;
Connecting plate 5 is z font, barycenter eccentric setting, makes connecting plate 5 have the trend of clockwise movement;
See accompanying drawing 2, bar hole successively through connecting plate 5 and pressing plate 7 rear portion after the top of bent axle 2 is connected with outer handle, and being socketed in one of them driving gearshaft of driving gear set 3, the position limiting structure 2-1 in bent axle 2 stage casing is arranged in the bar hole at pressing plate 7 rear portion; Another driving gearshaft of driving gear set 3 is connected with the connecting bushing of switch 9-3 gate; One end of pressing plate 7 is fixedly installed in installing rack 4, and the other end is positioned at the below of the vertical groove of socket 9-2 circumference; One end of slide plate 6 is connected with connecting plate 5, and the other end is between pressing plate 7 and socket 9-2, and the snap fit of slide plate 6 is positioned at the anterior right side of pressing plate 7; Pillar in installing rack 4 is through the bar hole of pressing plate 7 front portion, and back-moving spring 8 is socketed on pillar, and back-moving spring 8 provides support and restoring force for pressing plate 7.
See accompanying drawing 3,5, when the state that plug does not insert, the position limiting structure 2-1 in bent axle 2 stage casing is arranged in the bar hole at pressing plate 7 rear portion, and the snap fit of the front portion blocks slide plate 6 of pressing plate 7, therefore cannot rotary crankshaft 2, namely cannot drive the combined floodgate that driving gear set 3 is carried out switch 9-3;
See accompanying drawing 4,6, when the state that plug inserts, in plug access socket 9-2, the convex edge 1 of pin head arranges vertical groove from socket 9-2 circumference and passes, downward extruding pressing plate 7, makes the snap fit of slide plate 6 depart from the front portion of pressing plate 7 and the bar hole at the position limiting structure 2-1 of bent axle 2 disengaging pressing plate 7 rear portion, now rotary crankshaft 2, connecting plate 5 and driving gear set 3 are rotated with the rotation of bent axle 2, can realize the combined floodgate driving driving gear set 3 to carry out switch 9-3; After combined floodgate due to switch 9-3, slide plate 6 is driven by connecting plate 5 and produces displacement, and its snap fit moves to above the convex edge 1 of pin head, and plug cannot be extracted;
