Abstract
The utility model discloses a simple structure, easy operation, and accurate position locking and intuitionistic displaying draw out type switchgear feeding apparatus. The utility model utilizes the mechanical lever theory. A revolving disk with a spanner is rotatablely fixed on the bottom plate of the drawer. A cylinder type block of the revolving disk which is vertical with the rotating plate surface presses a displaced position guard gib which is arranged in the middle of the drawer pallet. A drawer unit can be moved in a composite direction of the acting force by the effect of the reaction force of the displaced position guard gib. The utility model is very easy to operate because the distance between the spanner and the revolving center is multiple times than that of the cylinder type blocks and the revolving center. The position locking and unlocking devices are provided with a revolving disk which has a function of exerting force, so that the utility model has the advantages of accurate position and simple structure. The position displaying device adapts a crank-slider mechanism. The position displaying device is articulately connected with the revolving disk with exerting force function through a connecting bar. The position of the position displaying device and the window indirectly react the relative position of the mobile drawer unit.
Description
Affiliated technical field
The utility model relates to low pressure pull-out type switchgear assembly cabinet, a kind of specifically low pressure drawer-type switch cabinet propulsive mechanism.
Background technology
At present, the low pressure drawer-type switch cabinet that uses on the market, many products that still adopt old standard production promptly have only connection, extract two grafting and demonstration out, and generally do not establish locking device.New national standard is formulated with reference to the like product international standard, regulation pull-out type low-voltage complete equipment must have three demonstrations, location and operation locking, increase test position, the secondary plug-in unit is communicated with during this position, outlet plug breaks away from, and cell gate is not opened when requiring test position, does not reduce the shell protection grade.In order to adapt to new national standard, each producer improves design on the basis of former two propulsive mechanisms, designs cycle type and propulsive mechanism rotating disc type, cycle type complex structure; Rotating disc type is that so-called machete slice structure is simple, but effort and easily produce misoperation.
Summary of the invention
In order to overcome existing low pressure drawer-type switch cabinet with propulsive mechanism complex structure, effort or produce the misoperation problem, the utility model provide a kind of simple in structure, rapid operation and lock-bit accurately, show position drawer-type switch cabinet propulsive mechanism intuitively.
The utility model drawer-type switch cabinet propulsive mechanism, comprise the driving that is installed on the removable drawer unit, lock-bit and release, the position displacement gathering sill at lever position indicator and traversing guide that is fixed in switch cabinet drawer supporting plate both sides and drawer supporting plate middle part, drive unit on the removable drawer unit is a rotating disk that has spanner, above-mentioned rotating disk center is rotating to be fixed on the drawer-bottom board, card is provided with a cylindric shifting block perpendicular to turntable surface under this rotating disk, this shifting block stretches in the corresponding with it position displacement gathering sill in drawer supporting plate middle part, and the position displacement gathering sill is that a groove width is suitable with above-mentioned cylindric shifting block diameter and with moving direction the slot mesh groove of one angle a is arranged; Lock-bit and tripper, comprise the locating detent that moves radially along rotating disk, locating detent is pulled to the back-moving spring of rotating disk, bearing pin, handle is articulated on the drawer-bottom board by bearing pin, handle is slidingly connected with the drive piece of locating detent afterbody, also be provided with three short slots that coincide with the lock pin nose shape on the described rotating disk circular arc, when locating detent inserts short slot, the restriction rotating disk rotates and forms lock-bit, release when breaking away from short slot, the locating detent that above-mentioned three short slots and straight line move is at once, removable drawer unit is in connection respectively, test, separate three positions, and the position display plate in the lever position indicator is directly connected with the rotating disk hinge by connecting rod, constitute slider-crank mechanism, position display plate and rotating disk interlock, three short slots and the locating detent that moves radially connect on the display panel accordingly respectively to timing, test, separating printed words and form aligns.
The beneficial effects of the utility model are: this propulsive mechanism adopts the mechanical lever principle, the centre of gyration of rotating disk is the fulcrum of this lever, be the impetus of this lever perpendicular to the cylindric shifting block of turntable surface, the handle fixing with rotating disk is the point of application of this lever, what cylindric shifting block was used for drawer supporting plate middle part with masterpiece has the position displacement gathering sill of an angle a with moving direction, under the effect of position displacement gathering sill reaction force, the removable drawer unit of the immobilization carrier of fulcrum and fulcrum, the direction opposite to force direction moves, because spanner to the distance of the centre of gyration is several times as much as the distance of cylindric shifting block to the centre of gyration, so this mechanism is very laborsaving, thereby again owing to there is the traversing guide of switch cabinet drawer supporting plate both sides to guarantee that removable drawer unit straight line steadily moves, and lock-bit and tripper have directly locked the rotating disk of application of force effect, accurate positioning, simple in structure, lever position indicator, adopt slider-crank mechanism, with connecting rod that the position display plate is directly hinged with the rotating disk that plays application of force effect, position display plate and form institute are to the removable drawer unit relative position of position indirect reaction.
