A kind of push-rod assembly
Technical field
The utility model relates to a kind of improvement of push-rod assembly, refers in particular to a kind of simple in structure, push-rod assembly that cost is low, easy to use.
Background technology
During available circuit is controlled, breaker of plastic casing is normally controlled by motor-operating mechanism, to realize combined floodgate, disconnection, reclosing; During use, breaker of plastic casing is connected on circuit; By the operation to motor-operating mechanism, to realize, the break-make of circuit is controlled.In motor-operating mechanism, conventionally can be provided with push-rod assembly, in case of emergency, press the button on push-rod assembly, can make motor-operating mechanism, make breaker of plastic casing work open circuit.The complex structure of existing push-rod assembly, cost is high.For this reason, we develop a kind of simple in structure, push-rod assembly that cost is low, easy to use.
Utility model content
The utility model object is that a kind of simple in structure, push-rod assembly that cost is low, easy to use is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of push-rod assembly, comprises push rod, button; Described push rod is flat; Insert in the cavity of button on the top of described push rod; On the lower surface of described button, be provided with uncinus; On described push rod, be provided with groove; The lower edge of described groove is more outstanding than upper edge; The hook portion of described uncinus is hooked on the upper edge of groove; On described push rod, be arranged with spring; Described spring is between the lower surface of described button and the lower edge of groove.
Preferably, between the upper end of described push rod and the top of the cavity of button, be provided with gap.
Preferably, described groove is arranged on face narrower on push rod.
Preferably, described groove is arranged on different face narrower on push rod in couples.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
In push-rod assembly described in the utility model, button is arranged on push rod by uncinus, and spring is between the lower surface of described button and the lower edge of groove; When pressing button, uncinus can move in groove, and button is under the effect of spring, can not come off; The utility model is simple in structure, and cost is low, easy to use.
