Description
Technical field
The utility model relates to a kind of electric equipment and manufactures field, and more particularly, it relates to a kind of twin-power switch interlocking device.
Background technology
The effect of twin-power switch is: when a road power failure (has a power failure, under-voltage, overvoltage, disconnected phase, frequency shift (FS)) time, twin-power switch makes to automatically switch between power supply, to ensure reliability and the fail safe of power supply, be widely used in skyscraper, community, hospital, airport, harbour, fire-fighting, metallurgical, chemical industry, weaving etc. does not allow the important place had a power failure, realize unattended operation to power continuously, the damage of power equipment is caused in order to prevent power supply from connecting simultaneously, twin-power switch is often all provided with interlocking device to ensure only having a road power supply to connect.
At present, application number is the interlock that the Chinese patent of CN201110197413.X discloses a kind of twin-power switch, it comprises mounting base, installing rack and two mains switches, the surrounding of described mounting base has chimb, described installing rack takes the shape of the letter U, opening direction, and to be fixed in mounting base in the heart down, also comprises interlocking lever; Described mains switch is placed on mounting base, is positioned at the both sides of installing rack, and is fixed by screw and installing rack; The center of described installing rack is provided with rotating shaft; The center of described interlocking lever has the hole of matching with rotating shaft, and is movably fixed on installing rack by rotating shaft; The two ends of described interlocking lever are equipped with U-shaped interlock slot; The size of described interlock slot is corresponding with the control lever size on mains switch, and control lever can drive interlocking lever to rotate by interlock slot.The interlock of this kind of twin-power switch, although structure is simple, can force to ensure single conduction by mechanical force, maintainer cannot make power supply close, for maintainer brings the risk of electric shock when overhauling circuit simultaneously.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of twin-power switch interlocking device that major-minor power supply can be made simultaneously to close.
For achieving the above object, the utility model provides following technical scheme: a kind of twin-power switch interlocking device, comprise two mains switches, installing rack and interlocking block, described interlocking block is provided with interlocking lever, described mains switch is fixed on the both sides of described installing rack, described each mains switch comprises shifting block, described interlocking lever two ends and described each shifting block connect one to one, described installing rack is provided with stirs the parallel chute in direction with shifting block, slide block is slidably connected in described chute, described slide block and interlocking block hinged, the off end of described each mains switch is towards identical, position, described chute stroke end makes interlocking lever promote and locks each shifting block to hold to off.
By adopting technique scheme, when interlocking block is positioned at normal operating conditions, interlocking lever rotates, drive interlocking lever rotates, and interlocking lever wherein will dial in ON end or OFF end, because interlocking lever is rigid body by a shifting block, so another shifting block is inevitable dialled in one end contrary with the former, in whole process, each shifting block acts on simultaneously, ensure that the continuity of power supply; When circuit needs maintenance to require that mains switch is in OFF end simultaneously, slide block drives interlocking block to push away forward, makes two shifting blocks dial in OFF end, because slide block cannot oppositely movement simultaneously, therefore ensure that shifting block cannot dial in ON end simultaneously, therefore, the utility model both ensure that interlocking capability, can ensure down circuitry again in special circumstances, for maintainer brings safety with convenient, chute and slide block mechanism not only structure are simple, and dependable performance, and have good guidance quality.
The utility model is set to further: described each shifting block is along being equipped with through slot perpendicular to the direction of stirring path, drive link is equipped with in described through slot, the diameter that is wide and described each drive link of described each through slot is all equal, and described each drive link is hinged with the two ends of described interlocking lever respectively.
By adopting technique scheme, utilize drive link by ingenious for the interlocking block rotary motion that horizontal revolving motion must be converted in perpendicular, there is transmission process light and handy, smooth, the advantages such as collisionless, contrast prior art, differential seat angle when U-shaped driving lever is owing to rotating, will inevitably and shifting block between there is inevitable gap, the mutual collision in use procedure because gap produces larger noise, and gap reduces the positioning precision of shifting block simultaneously, reduce interlock switch reaction speed, affect the fail safe of switch entirety, after improvement by drive link and interlocking block hinged in horizontal direction, and move with chute aid conductive, reach and stir gapless, improve interlocking precision, accelerate the reaction speed that interlock switch switches, increase the object of fail safe.
The utility model is set to further: described installing rack is provided with V-type locating piece, and the symmetry axis of described V-type locating piece overlaps with the center line of described chute, and the V-type that the one side of the relatively described V-type locating piece of described interlocking block is provided with for locating is top.
By adopting technique scheme, in promotion slide block process, by the position-limiting action of V-type locating piece, interlocking block can be in center position voluntarily, make interlocking lever coaxial with each drive link when interlocking block is in chute stroke end, the each shifting block of further guarantee is in OFF end and there will not be the incomplete phenomenon of locking, and increase interlocking block is in locking ability during closed condition, improves switch overall security and practicality.
The utility model is set to further: be provided with apical grafting spring in described chute, and the side of described chute is provided with spring catch.
By adopting technique scheme, apical grafting spring anti-limited slip block is set when normal operating conditions because the reason such as vibrations and from line slip, surprisingly trip to closed condition when avoiding power supply to connect, the setting of spring catch is unlikely to be ejected by apical grafting spring to withstand slide block when mains switch is in closedown simultaneously, improve fail safe during closed condition, improve the convenience in twin-power switch routine use, increase product function and quality.
The utility model is set to further: described spring catch comprises spring, lever and shank, described shank and lever hinged, described lever and described installing rack hinged, described shank is placed in described spring, described both ends of the spring respectively with described installing rack and shank inconsistent, the working end of described shank is provided with the inclined-plane held towards described shifting block on.
By adopting technique scheme, the setting on inclined-plane is in order to slide block can be allowed to push the other end from normal working end smoothly, after maintainer completes maintenance, only lever need be gently pressed, spring catch is just in retractable pin-and-hole, and slide block, under the effect of apical grafting spring, gets back to normal operating conditions instantaneously, this device is not only convenient, practical, thus further increases property easy to use of the present utility model.
