Description
Technical field
The utility model relates to low-voltage drawing out type electric equipment, especially a kind of hand positioning drawer propulsion system.
Background technology
Drawer is the pull switch equipment efficient apparatus that especially switch cubicle is closed a floodgate and disconnects, and about its propulsion system, is described in the prior art more.In the document 1 of prior art (application number CN200810019160.5), the rotating disk of its propulsive mechanism is not a kind of pattern of three positions, it is in the progradation of drawer, need the operator manually to determine the corresponding relation of amount of spin and stroke with seeing service, for transmission mechanism, with the corresponding relation of stroke, have relatively high expectations, what is more important, for rotating disk, its locking interlocking device is only a kind of state locking under certain stroke state, and not for special further locking under connection status; Although it is provided with a kind of locking for external rotating shaft place when closing a floodgate, this locking is not at first for rotating disk, and the reliability of this locking is low, and it can not be automatically locked, and complex structure.At first this set requires high to transmission device, therefore cost raises, and it is inadequate for the degree of protection under connection status, makes the connection status poor stability of drawer, and safe coefficient reduces.
In the document 2 (CN200420049900.7) of prior art, a kind of Water charging drainage means (MG100) of flush toilet is disclosed, the pattern that its three positions rotating disk is arc, complex structure, processing difficulties, and stability and reliability lower, rolling disc is when link position, and dead bolt, by the form of linkage rod slide block mechanism, is locked rotating disk simultaneously.This locking reliability is low, is unfavorable for the safety requirements under "on" position.
In the document 3 (CN200810234625.9) of prior art, a kind of Water charging drainage means (MG100) of flush toilet of three positions is disclosed, three positions of its rotating disk are the patterns by lock slots, it has all carried out the state locking for three location statuss in the drawer traveling process, has had three position rotating disks.The stop pin that its lock hole with in three position rotating disks matches is manual drawing, have spring, and it can be touched auxiliary switch by mechanical rocker arm in the process of drawing, thereby realize outage or the energising of auxiliary switch; But, in the location status after combined floodgate, it also only carries out the fixing of position by a locking mechanism of the interlocking for rotating shaft.It is not equally for rotating disk, and the reliability of this locking is low, and it can not be automatically locked, and complex structure.At first this set requires high to transmission device, therefore cost raises, and it is inadequate for the degree of protection under connection status, makes the connection status poor stability of drawer, and safe coefficient reduces.
The utility model content
In order to overcome above-mentioned defect, the utility model aims to provide a kind of draw out switchgear cabinet drawer propulsion system, the multiposition rotating disk of this system can be locked a plurality of positions in the drawer traveling process reliably, and there is the further locking under "on" position for this multiposition rotating disk simultaneously, this locking is reliable, lock-out state is stable, can improve the safety and reliability of "on" position, avoids misoperation.
The scheme adopted is as follows:
A kind of draw out switchgear cabinet drawer propulsion system, it has fixed mount, install one on fixed mount and advance spiral, on this propelling spiral, have many can with drawer-bottom board on the spiral groove of keeper interlock, described propelling spiral has the driving shaft that stretches out fixed mount the place ahead, has the interface that drives spanner for connecting on described driving shaft;
Sleeve gear is installed regularly on described driving shaft, sleeve gear is engaged with locating wheel, described locating wheel has front end face and rear end face, on the neighboring of the rear end face of locating wheel, a plurality of drawer advanced positions location notchs are set, a locating shaft is installed on fixed mount, have on locating shaft and locating shaft can be biased toward to the retainer spring of locating wheel, locating shaft can coordinate with described drawer advanced positions location notch, for positioning when drawer advances to diverse location; At a position indicating dial of the central area of the front end face of locating wheel fixed installation, described position indicating dial is used to indicate the advanced positions of drawer; A lock slots radially is set on the leading flank of locating wheel, and described lock slots is for coordinating with outside bolt, thus the rotation of can lock in place taking turns.
Valuably, the quantity of described drawer advanced positions location notch is three.
Valuably, after locating wheel is positioned the axle location, lock slots moves to the correct position that can coordinate with the other end of described bolt.
By said system, reliably a plurality of positions in the drawer traveling process are locked, and there is the further locking under "on" position for this multiposition rotating disk simultaneously, this locking is reliable, lock-out state is stable, has improved the safety and reliability of "on" position, avoids misoperation.
