Description
Technical field
The utility model relates to a kind of transmission mechanism for valve of switch cabinet.
Background technology
Transmission mechanism for valve of switch cabinet is the device that a kind of horizontal throw by circuit breaker cart push-and-pull is converted into the stroke up and down of valve arrangement switching; A kind ofly to realize circuit breaker cart push-and-pull and valve arrangement opens and closes chain a kind of device.Its principle is under the effect of handcart valve driving shaft, and transmission mechanism for valve of switch cabinet is converted into this effect the driving stroke of valve arrangement, and valve mechanism is produced and effectively opens and closes displacement.
The problem that existing design exists is: 1, miniaturization circuit breaker cart stroke is little, valve drives effective travel short, conventional transmission mechanism for valve is difficult to this variable to be converted into the degree that opens and closes valve, or after transforming, power driving error is large, and valve is opened or closed not in place.2, between miniaturization circuit breaker cart contact arm and contact box, distance is little, require transmission mechanism for valve to carry out providing enough displacements that valve is reacted under less displacement at handcart, otherwise the situation that there will be handcart contact arm and valve plate to collide, causes valve plate distortion, exists hidden danger is installed.3, conventional transmission mechanism is only one-sided fixing with cabinet sidewall, when transmission mechanism is stressed, easily deforms, and affects the effective transmission displacement of transmission mechanism, causes the valve can not smooth opening or closure.
Summary of the invention
For solving the problems referred to above of existing design, the utility model provides a kind of switch cabinet shutter drive mechanism, its technical scheme of taking is: comprise fixed head, drive pressing plate, lower valve connecting rod and upper valve connecting rod, the left part of fixed head front face is fixed with perpendicular major axis, its right part is fixed with bearing pedestal, the front portion of major axis is socketed with axle sleeve, drive the left end of pressing plate to be fixed on the front end of axle sleeve, the left end of lower valve connecting rod is fixed on the rear end of axle sleeve, the left part of upper valve connecting rod is fixed on the front end of bearing pedestal, and upper valve connecting rod can rotate along bearing pedestal, the left part of lower valve connecting rod has horizontal driver slot, the left part of upper valve connecting rod front face is fixed with perpendicular minor axis, the front end of minor axis is plugged in driver slot, when circuit breaker cart is in the time testing position, drive the right-hand member updip of pressing plate, the handcart valve driving shaft on circuit breaker cart is positioned at the projection right side place that drives pressing plate end face left end, and the front end of minor axis is positioned at the left end of driver slot, when circuit breaker cart is during in working position, drive pressing plate level, handcart valve driving shaft is positioned at and drives pressing plate end face right-hand member, and the front end of minor axis is positioned at the right-hand member of driver slot.
The utility model by with the interaction of handcart valve drive mechanism, in the time that handcart advances very small distance, can produce compared with big displacement quantity, and act on valve arrangement valve is opened; In the time that handcart exits, can produce the reverse displacement of equivalent, act on valve arrangement valve is closed.Rotation place of the present utility model adopts bearing, rotates flexible frictional force little; Drive plate and valve win in succession between transmission, conversion simple, drive gap is little, precision is high; Valve mechanism adopts steel plate to fix, and intensity is high, and not yielding when transmission, driving error is little; Transmission efficiency is high, and the displacement being transformed by handcart stroke is large, can effectively guarantee the opening and closing of valve arrangement.
The utlity model has complete property strong, be convenient to install the feature such as structural strength is high, strong adaptability.
