Abstract
Automatic transfer switching equipment with a mechanical interlocking function comprises a base plate, a motor, two execution switches, two escapements, a mandrel, a controller and a housing. The lower end of the inner side end of each escapement is provided with a groove matched with a corresponding deflector rod on the mandrel, and the outer part of the groove protrudes outwards and forms a long-tail-shaped projection. The middle parts of the two escapements can be respectively arranged on two side surfaces of a motor support in an up-down moving manner. The outer side end of each escapement is contacted with a handle on one execution switch. According to the utility model, the long-tail-shaped structures of the escapements are adopted to ensure that the deflector rods on the mandrel never depart from the escapements and the mandrel rotates along with the movement of the escapements. In this way, when the escapement on one side moves up, the power supply on the side is closed, and the escapement on the other side fails to move up to close the power supply of the same side, so that by adopting the mechanical interlocking of the two escapements, the two execution switches are prevented from being closed at the same time; in addition, additional mechanical interlocking devices are not needed, so that the numbers of parts and assembling processes can be reduced, and the cost is reduced.
Description
Technical field

But, there is following point in the automatic transfer switching electric appliance of this prior art: for automatic transfer switching electric appliance, for fear of causing danger, do not allow main power supply pairing, therefore conventionally a mechanical interlock 11 is set to prevent main power supply pairing in the upper surface of electric machine support 6, in the time that the escapement 4 of a side moves to upside, the power supply corresponding with this escapement 4 closes, now mechanical interlock 11 by the escapement 4 that stops opposite side move up come closed stand-by power source, ensureing that main power source closes when, stand-by power source in point state.But, because the part that needs utilization is extra is realized mechanical interlocking, therefore increased the quantity of part and assembling procedure, and caused cost to raise.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of automatic transfer switching electric appliance with mechanical interlocking function.
In order to achieve the above object, the automatic transfer switching electric appliance with mechanical interlocking function that the utility model provides comprises base plate, motor, two execution switches, two escapements, mandrel, controller and shells; Wherein motor utilizes electric machine support to be arranged in the middle part of the surface of base plate, and the output shaft of motor upwards runs through electric machine support middle part; Two execution switches are separately positioned on the backplate surface that is positioned at electric machine support both sides, and are connected with standby usage power supply respectively; One side surface of mandrel is provided with the axle sleeve being sleeved on motor output shaft, and opposite side spaced surface is fixed with two driving levers; Controller is arranged on surface one side of base plate, for controlling the running of motor; Shell covers on the outside of motor and two execution switches; Described escapement medial extremity bottom be formed with one with groove that on mandrel, corresponding driving lever matches, and the position that is positioned at groove outside is outwards given prominence to and is formed with a long-tail shape projection, the middle part of two escapements is separately positioned on the both side surface of electric machine support in the mode that can move up and down, outboard end contacts with the handle on an execution switch.
Middle part, outer end towards another escapement in described long-tail shape projection is formed with an arc-shaped slot.
The automatic transfer switching electric appliance of mechanical interlocking function that what the utility model provided have is to ensure that by the long tail-shaped structure of escapement the driving lever on mandrel does not leave escapement all the time, mandrel is rotated with the motion of escapement, like this when a side-hold is vertical while moving to top, this side power supply closes, opposite side escapement can not move to top to be come should side power supply utilizes the mechanical interlocking of two escapements to avoid two execution switch pairings thus.In addition, due to without mechanical interlocks is set in addition, therefore can reduce the quantity of part and assembling procedure, reduce costs simultaneously.
