Abstract
The utility model relates to a drawer propulsion interlocking mechanism comprising a propulsion mechanism, a main driving wheel, a transmission positioning mechanism and a locking mechanism; an interlocking mechanism comprises a positioning locking bar, a force transmission mechanism and a position lock notch; the position lock notch is arranged in the outer circumference surface of a drive worm; when the positioning mechanism is at the working position, the position lock notch faces the insertion direction of the positioning locking bar; the force transmission mechanism is connected with a rotating part arranged at a front support and drives the positioning locking bar to be inserted into the position lock notch along the radial direction so as to enter the locking position or to be far away from the position lock notch so as to enter the non-locking position. As the position lock notch on the drive worm can face the insertion direction of the positioning locking bar only when equipment is at the working position, the potential safety hazards caused by false closing operation when the equipment is at the non-working position can be avoided. In addition, when an operating handle is at the closing position, the positioning locking bar directly locks the drive worm, thus avoiding misoperation when a switch is at the closing position, and improving the safety of the mechanism.
Description
Technical field
The utility model relates to the low pressure draw out switchgear, relates in particular to a kind of Water charging drainage means (MG100) of flush toilet.
Background technology
The distribution industry is as the key industry of country, and its equipment reliability of applying and fail safe are concerning the national economic development and masses' security of the lives and property.Low tension switch complete set of equipments application surface is extremely wide, but operating personnel's professional skill is uneven, for the operational procedure of equipment and understanding not all fully.With regard to the low pressure draw out switchgear, it comprises drawer at least and separates with cabinet, experiment and connect three service positions and open a sluice gate, two generic operations close a floodgate, it is unclear for the operation sequence of above-mentioned three service positions the most outstanding performance of misoperation occurring, such as opening when the off-position, closing operation, the hand arm of incorrect use and take hard push-pull fashion operating drawer, also force to carry out hand or the like when perhaps drawer has arrived end of travel, these misoperations damage the drawer propulsive mechanism easily, cause functional unit generation mechanical breakdown, normal power supply of influence and maintenance.
CN201189975Y discloses a kind of interlocking device of big interlocking propulsive mechanism, this interlocking device comprises main switch interlock dish, rotating lever and interlocking baffle plate, described main switch interlock dish links with the contactor handle of big drawer type functional unit, it is provided with breach, the central authorities of described rotating lever are hinged on the housing, the one end stretches in this breach and by main switch interlock dish and stirs, the other end is articulated on the interlocking baffle plate, described interlocking baffle plate is a strip, offer chute on it, this chute is sheathed on the sliding pin that is fixed on housing, and this sliding pin is a screw, and this interlocking baffle plate can laterally move by chute and sliding pin.In the time of need preventing misoperation, the interlocking baffle plate can be moved to the outer end of cardan shaft, can play the effect of the inner hexagonal hole that covers the cardan shaft outer end.
Such scheme has to a certain degree reduced the possibility of misoperation, but also exists than significant disadvantages:
1, interlocking device is independent of the service position operating mechanism, when equipment is in off-position, and the outer end of also can operation interlocking mechanism covering cardan shaft.
2, owing to there is not locking device, interlocking device may be subjected to displacement under external force, causes can't realizing covering the outer end of cardan shaft, has potential safety hazard.
3, be in the service position at equipment, and implement under the situation that cardan shaft is not extracted to close a floodgate damage equipment.
When being in off-position, equipment covers cardan shaft in order to prevent interlocking device, CN101117119A discloses a kind of low pressure drawer type driving mechanism applied for switchboard drawer, comprise precession mechanism and three position locking mechanisms, precession mechanism urges drawer moves in cabinet, when drawer is advanced to each service position successively, three position locking mechanisms locking precession mechanism prevents that it is in off-position.Particularly, described three position locking mechanisms comprise three location positioning dishes, trip lever and make the driving gear set of three location positioning dishes with the interlock of transmission worm screw; On trip lever, offer and separate locked groove, three location positioning dishes are provided with location notch, trip lever is equiped with the back-moving spring that trip lever is resetted, when drawer need advance, by mobile trip lever positioning disk is embedded and separate locked groove with release three location positioning dishes, when drawer was advanced to assigned address, trip lever resetted under the effect of back-moving spring, snap in location notch on the three location positioning dishes to lock three location positioning dishes, the equipment of preventing is in off-position.Simultaneously, the lower baffle plate of combined floodgate junction panel blocks the rocking handle operating axis, makes rocking handle can't enter operation, the dop of combined floodgate junction panel upper end snaps in separating in the locked groove of trip lever, make the trip lever can't release, switch be in the lock state, and ensures that drawer enters lock-out state and normally moves.
The shortcoming of technique scheme is:
1, increased parts, as three location positioning dishes, trip lever, back-moving spring, travel switch push rod and spacer pin etc., especially three location positioning dishes have increased the thickness of driving gear set, make that the structure of equipment is more complicated.
2, make operation sequence more loaded down with trivial details, carrying out any operation all needs earlier three position locking mechanisms to be carried out release.
In addition, also there is common defective in technique scheme: owing to all adopt the mode of the spiral protrusion mating groove shape turbine piece skewed slot of transmission worm screw to realize the rectilinear motion of drawer, spiral protrudes and the field of conjugate action of skewed slot has certain angle to the direction of motion to drawer.Therefore, under external force, transmission worm screw and flute profile turbine piece can produce and relatively move, and cause the position of drawer to be subjected to displacement easily, have bigger potential safety hazard.In order to prevent the drawer displacement, must reduce the tooth matching angle of transmission worm screw and flute profile turbine piece, can finish the work just need to rotate the more number of turns for this reason.
The utility model content
Technical problem to be solved in the utility model is to avoid covering the handle hole of cardan shaft when equipment is in off-position, guarantee simple and compact equipment structure, and is easy and simple to handle.
Further, the utility model has also solved between transmission worm screw and the flute profile turbine piece can't self-locking, and the problem and the interlocking device that are easy to generate relative displacement may be subjected to displacement under external force, have the problem of potential safety hazard.
For this reason, the technical scheme that the utility model adopted is:
A kind of Water charging drainage means (MG100) of flush toilet comprises:
