When closed position, operation handle closure, however, being also suffered from certain drawbacks in practical application, i.e., when event occurs in circuit
Barrier, when personnel being needed to overhaul, the operation handle of automatic reclosing brake mechanism drives open circuit due to accidentally being hit or by people's maloperation
The handle of device closes a floodgate and then connects circuit, to bring very big security threat to service personnel.
Summary of the invention
It, can be in view of the deficiencies of the prior art, the present invention intends to provide a kind of breaker self-lock protection machine
STATEMENT OF FEDERALLY SPONSORED associated with operation handle is lockked, miniature circuit breaker is prevented to be closed again.
To achieve the above object, the present invention provides the following technical scheme that
A kind of breaker self-lock protection mechanism, including shell and the STATEMENT OF FEDERALLY SPONSORED being connected with operation handle, in shell
Inside it is provided with snap close piece, latch spring, swing component and buckle releaser mandril；The snap close piece can move up and down in shell, and
And outside the extended bonnet lock hole being set on shell, the snap close piece is equipped with upper lock section and the lower lock matched with STATEMENT OF FEDERALLY SPONSORED
Portion；One end of the latch spring is immobilized in the shell, and the other end is connected with snap close piece, and snap close piece can be driven to stretch out bonnet lock hole
Outside；The swing component is hinged in shell, and the lower end of the swing component and buckle releaser mandril are inconsistent, the swing component it is upper
End is provided with swing spring, and the upper end is equipped with the clamping portion matched with upper lock section；When buckle releaser mandril is to Forward
The lower end of dynamic pressing swing component, the upper end of the swing component can compress swing spring, the clamping portion and upper lock section phase point
From latch spring can drive snap close piece to stretch out outside bonnet lock hole at this time, so that will drive lower lock section moves up latching STATEMENT OF FEDERALLY SPONSORED.
The present invention is further arranged: the shell is equipped with indicating window, and the indicating window is placed in the top of swing component.
The invention has the advantages that: technical solution of the present inventions, move up latching STATEMENT OF FEDERALLY SPONSORED by the lower lock section of snap close piece,
It is now in the STATEMENT OF FEDERALLY SPONSORED of open position, lower lock section will limit STATEMENT OF FEDERALLY SPONSORED and move down, so that STATEMENT OF FEDERALLY SPONSORED can not move down back
To closed position, so that operation handle is closed again, when needing to release the locking-in state of STATEMENT OF FEDERALLY SPONSORED, stretching shell need to be only pressed
The end of external lock fastener, the snap close piece can move down, and lower lock section can release the limitation to STATEMENT OF FEDERALLY SPONSORED, at this time the card of swing component
Socket part can be matched with upper lock section again under swing spring effect, prevent snap close piece from moving up under latch spring effect
It stretches out outside bonnet lock hole, structure is simple, convenient for operation.

Specific embodiment
A kind of breaker self-lock protection of the invention mechanism is described in further details referring to attached drawing 1 to Fig. 2.
A kind of breaker self-lock protection mechanism, including shell 1 and the STATEMENT OF FEDERALLY SPONSORED being connected with operation handle 23, in shell
Snap close piece 4, latch spring 5, swing component 6 and buckle releaser mandril 7 are provided in body 1；The snap close piece 4 can be in shell 1 on
Lower movement, and extended shell 1 be arranged bonnet lock hole 11 outside, the snap close piece 4 be equipped with upper lock section 41 and with 3 phase of STATEMENT OF FEDERALLY SPONSORED
The lower lock section 42 of cooperation；One end of the latch spring 5 is fixed in shell 1, and the other end is connected with snap close piece 4, can be driven
Snap close piece 4 stretches out outside bonnet lock hole 11；The swing component 6 is hinged in shell 1, the lower end and buckle releaser top of the swing component 6
Bar 7 is inconsistent, and the upper end of the swing component 6 is provided with swing spring 8, and the upper end is equipped with and matches with upper lock section 41
Clamping portion 61；When buckle releaser mandril 7 moves forward the lower end of pressing swing component 6, the upper end of the swing component 6 can be compressed
Swing spring 8, the clamping portion 61 are separated with upper 41 phase of lock section, and latch spring 5 can drive snap close piece 4 to stretch out bonnet lock hole 11 at this time
Outside, STATEMENT OF FEDERALLY SPONSORED 3 is lockked to will drive lower lock section 42 and move up.
It is moved up by the lower lock section 42 of snap close piece 4 and locks STATEMENT OF FEDERALLY SPONSORED 3, be now in the STATEMENT OF FEDERALLY SPONSORED 3 of open position, under
Lock section 42 will limit STATEMENT OF FEDERALLY SPONSORED 3 and move down, so that STATEMENT OF FEDERALLY SPONSORED 3, which can not move down, returns to closed position, thus operation handle 2
It is closed again, when needing to release the locking-in state of STATEMENT OF FEDERALLY SPONSORED 3, need to only press the end for stretching out 1 external lock fastener 4 of shell, it is described
Snap close piece 4 can move down, and lower lock section 42 can release the limitation to STATEMENT OF FEDERALLY SPONSORED 3, and the clamping portion 61 of swing component 6 can swung at this time
It under spring 8 acts on, is matched again with upper lock section 41, prevents snap close piece 4 from moving up stretching lock under the effect of latch spring 5
Outside hole 11, structure is simple, convenient for operation.
The shell 1 is equipped with indicating window 12, and the indicating window 12 is placed in the top of swing component 6, can pass through indicating window
12 observe the location of swing component 6, to judge whether snap close piece 4 locks STATEMENT OF FEDERALLY SPONSORED 3, improve its security performance.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
