see also Fig. 5, Fig. 6 and Fig. 7; The described push pedal 2122 of the utility model is provided with passing through that the iron core 21211 of the magnet 2121 that is used to supply power passes and is provided with chamfered section 212241 through hole 21224 near electromagnet 2121 sides described in hole 21224.Above-mentioned structure makes the iron core 21211 of working as electromagnet 2121 stretch out electromagnet 2121 and promote and at first clashes into chamfered section 212241 in the process of push pedal 2122, thereby push pedal 2122 rotations are passed through hole 21224 until iron core 21211.Push pedal 2122 hub settings are specially the first hub setting end 212271 and penetrate in first mating holes 21131 of pedestal 211 in pedestal 211, and the second hub setting end 212272 penetrates second mating holes 21133 of pedestal 211.Synchronous, the limit chamber 21228 of push pedal 2122 cooperates qualification with positive stop end 21132 on the pedestal 211, and described positive stop end 21132 plays the effect of qualification push pedal 2122 move left and right.The strike end 21225 of push pedal 2,122 one ends is used to hit the dropout end of circuit breaker operation mechanism 3 and realizes that its separating brake moves; Push pedal 2122 other ends are provided with the stop cavity 21226 that cooperates with arresting lever 2131; Described stop cavity 21226 is arranged on a side that is close to the described second hub setting end 212272; This stop cavity 21226 comprises first stop cavity 212261 and second stop cavity 212262 that is used for cooperating with arresting lever 2131; First stop cavity 212261 and second stop cavity 212262 are separated by jut 212263, and arresting lever 2131 slides in first stop cavity 212261 and second stop cavity 212262 through arc surface 21314.
Fig. 7 please be continued to consult in ; The described stop assembly 213 of the utility model comprises arresting lever 2131, elastic force spring 2132 and pivot 2133; Described arresting lever 2131 is a bar shaped lever, and an end of arresting lever 2131 is flat press section 21311, is used for the external force operation; The middle part of arresting lever 2131 is provided with hub setting circular hole 21312 and is used to cooperate pivot 2133; Make arresting lever 2131 in pedestal, can swing; Be specially: arresting lever 2131 passes through pivot 2133 hub settings on the hub setting seat 2112 on the pedestal 211; Described hub setting seat 2112 comprises that one is positioned at hole and on pedestal 211 side plates and is positioned at the inner arch cavity of pedestal 211, thereby realizes its hub setting function; The other end at arresting lever 2131 is provided with stop end 21313, is formed with on the described stop end 21313 to be used for the vertical bending that cooperates with first stop cavity 212261, second stop cavity 212262.When push pedal 2122 was in initial position, push pedal 2122 this moment should be near electromagnet 2121, and the stop end 21313 of arresting lever 2131 stretches into second stop cavity 212262 of push pedal 2122, and relatively stable, thereby prevented rotating up of thrust plate 2122; When push pedal 2122 promotes and after the swing, stop end 21313 falls into first stop cavity 212261 and relatively stable through the iron core of electromagnet 2,121 21211, thus upwards swing of restriction push pedal 2122, promptly fixedly push pedal 2122 in the next.
Fig. 4 please be continued to consult in ; The utility model reset assembly 214 is installed on pedestal 211 inside; It comprises support 2141, and support 2141 inner hub settings have swivel mount 2142, and swivel mount 2142 front and back accommodate release link 2143 and elastomeric element 2144; Elastomeric element 2,144 one end in contact supports 2141, the other end is against swivel mount 2142.Swivel mount 2142 bottoms have the strike end (invisible among the figure) that matches with the rotating shaft of operating mechanism 3.Behind breaker open operation, the rotating shaft of operating mechanism 3 rotate in place and promotes above-mentioned strike end.Thereby swivel mount 2142 moves up, thus elasticity of compression parts 2144 release links 2143 follow and move up, promote to reset with the iron core 21211 help electromagnet 2121 of the coaxial electromagnet 2121 of release link 2143.
reset assembly 214 helps electromagnet 2121 to reset, if make above-mentioned trip assembley therefor 212 can realize its tripping function once more, in like manner, above-mentioned push pedal 2122 also should be replied upper.This reset function is pushed arresting lever 2131 through extraneous manpower usually, thus push pedal 2122 upwards swing (this spring force specifically describes as follows) under the spring force effect that adds, and stopping of the arresting lever after being resetted 2131 and rest on the home position.Certainly; Above-mentioned arresting lever 2131 also can be through being located at telecommunication assembly 215 reality in the controller 2; Telecommunication assembly 215 comprises the electromagnet 2152 that resets of mounting bracket 2151 and mounting bracket 2151; Reset electromagnet 2152 under external operation, arresting lever 2131 is promoted and realizes that it resets, to reach the effect of remote reset.
so that it rotates up, reply upper for the above-mentioned spring force that adds in push pedal 2122.We can add extension spring fixing hole 21229 in push pedal 2122, extension spring one end is fixed in the extension spring fixing hole 21229, and the other end is fixed on the pedestal 211, can realize above-mentioned returning spring power.
are in said process; Owing to change first push pedal in the prior art and second push pedal into a monolithic devices push pedal 2122; Make push pedal 2122 in swing, cooperate to such an extent that structure can be stablized with respect to employing first push pedal and second push pedal; Reliable work, and be difficult for taking place loosening with pedestal 211.
In sum, the technical scheme that the utility model provides has overcome the shortcoming in the prior art, has reached goal of the invention, has embodied the described technique effect of applicant
