The utility model content
The purpose of this utility model provides a kind of circuit breaker, influences the problem that bolt and swivel nut are not easy to assemble greatly in order to the swivel nut welding difficulty that solves circuit breaker crossbeam main frame and door-plate hermetically-sealed construction, and the crossbeam of circuit breaker is provided simultaneously.
For addressing the above problem, the utility model circuit breaker adopts following technical scheme: a kind of circuit breaker, comprise crossbeam, crossbeam comprises crossbeam main frame and door-plate, be provided with sealing strip between crossbeam main frame and the door-plate, the place of turning edge of described crossbeam main frame is provided with swivel nut, is installed with bolt on crossbeam main frame, sealing strip and the door-plate and assembles with swivel nut, described swivel nut is axially gone up near crossbeam main frame one end and has been wholely set projection, and this projection inserting is in bolt passes the hole of crossbeam main frame.
Described swivel nut is suspended from the crossbeam main frame horizontal ends, and the upper surface of swivel nut is concordant with the upper surface of the vertical end of crossbeam main frame, is with sealing ring on the projection of swivel nut.
Described bolt is near being with sealing gasket and another sealing ring on the door-plate outside, and the sealing circle is positioned at sealing gasket.
The upper surface of described sealing strip exceeds the vertical end of described crossbeam.
The utility model circuit breaker crossbeam adopts following technical scheme: a kind of circuit breaker crossbeam, comprise crossbeam main frame and door-plate, be provided with sealing strip between crossbeam main frame and the door-plate, the place of turning edge of described crossbeam main frame is provided with swivel nut, be installed with bolt on crossbeam main frame, sealing strip and the door-plate and assemble with swivel nut, described swivel nut is axially gone up near crossbeam main frame one end and has been wholely set projection, and this projection inserting is in bolt passes the hole of crossbeam main frame.
Described swivel nut is suspended from the crossbeam main frame horizontal ends, and the upper surface of swivel nut is concordant with the upper surface of the vertical end of crossbeam main frame, is with sealing ring on the projection of swivel nut.
Described bolt is near being with sealing gasket and another sealing ring on the door-plate outside, and the sealing circle is positioned at sealing gasket.
The upper surface of described sealing strip exceeds the vertical end of described crossbeam.
Adopt the circuit breaker and the crossbeam of this structure, the swivel nut at the hermetically-sealed construction place of circuit breaker crossbeam main frame and door-plate, has prevented from because of welding makes perforate that the distortion of crossbeam main frame causes crossbeam main frame and door-plate the problem of wearing property difference to be taken place by the projection inserting that is wholely set on the crossbeam main frame.
In addition, the projection of swivel nut and bolt be positioned at the door-plate outside axially on all be with sealing ring, prevented that rainwater from entering by screw thread, and the setting of sealing strip exceeds the crossbeam main frame and vertically holds, prevent that rainwater from accumulating between crossbeam main frame and door-plate.
