Specific embodiment
The embodiment of the present invention is described further below for attached drawing:
The present invention provides the present invention to provide a kind of twin-lock structure for omnipotent breaker comprising:
Lock body, including the first lock body 11 and the second lock body 12, the two setting side by side up and down, and the key being respectively provided with for key insertion
Keyhole；
First latch hook member 13, is arranged on the first lock body of upside, and with key turns and then limits the rotation of the second lock body, realizes
Limitation is circumferentially rotated to the second lock body；
Second latch hook member 14 is arranged on the second lock body, with key turns and then limits separating brake connecting rod, and the upper end can be by the first lock
The separating brake connecting rod 15 of hook limit, lower end and breaker constitutes limit cooperation.
Two lock bodies are directly fixed on fixed bracket 16, which is fixed on breaker body,
First lock body and the second lock body are arranged side by side, and the top of the second lock body is arranged in the first lock body, and the two keeps corresponding up and down and closes
System, while the first lock body and the second lock body are all made of lock body daily used and can be widely available from market.
And rear side linkage the first latch hook member 13 of setting of the first lock body 11, rear side linkage the second lock of setting of the second lock body 12
Hook 14, the two in the same plane, and the first latch hook member rotation when, it may appear that contradict above second latch hook member,
So that the case where the second latch hook member limitation rotation, therefore mechanism of first latch hook member as limitation the second latch hook member rotation, and the
Two latch hook members, which then have, to be constituted the first state of limit cooperation with separating brake connecting rod and releases the second state that limit cooperates, and the
When two latch hook members are in first state, the second latch hook member can be limited by the first latch hook member, so that it cannot be by the second lock body
Drive rotation.
First latch hook member 13 includes:
Interconnecting piece 131 is linked with the first lock body, which is equipped with the first strip-shaped hole 133, first lock body
It is equipped with the first STATEMENT OF FEDERALLY SPONSORED compatible with strip-shaped hole, i.e. first STATEMENT OF FEDERALLY SPONSORED is plugged in first strip-shaped hole, and by nut
It is fixed, so that the rotation of the first lock body can also drive the first latch hook member to rotate；
Limiting section 132 is extended to form from interconnecting piece to second latch hook member direction, and with the second latch hook member in same axis side
Limit cooperation is constituted upwards, and the effect of locking, institute may be implemented in the vertical direction wherein same axis indicates vertical direction
Limiting section is stated equipped with approaching side and confined planes, the smooth excessive setting of the two, the i.e. approaching side with certain circular arc in rotation
It more easily rotates, and confined planes and the second latch hook member is driven to constitute limit cooperation, the second lock is limited with the limit of vertical direction
The rotation of hook.
Second latch hook member includes:
Interconnecting piece 141 is linked with the second lock body, is equipped with the second strip-shaped hole 144, second lock body is equipped with and strip-shaped hole
Compatible second STATEMENT OF FEDERALLY SPONSORED 121, i.e., second STATEMENT OF FEDERALLY SPONSORED is plugged in second strip-shaped hole, and is fixed by nut, so that the
The rotation of two lock bodies can also drive the second latch hook member to rotate；
Retainer 143 is extended to form from interconnecting piece to the first latch hook member direction, and by first latch hook member in same axis side
Limitation circumferentially rotates upwards, when retainer is towards the first lock body, can be carried out by the rotation of the first latch hook member locking or
Unlock operation, and when in the unlocked state, the second latch hook member can just be driven by the second lock body and rotate, to carry out to breaker
Unlock or lock operation；
Locking part 142 is extended to form from interconnecting piece to separating brake connecting rod direction, and is located on same axis with retainer, and only
Limit cooperation is constituted when dynamic portion is limited with separating brake connecting rod, which, which is set, circumferentially to be revolved with the center of circle of the second lock body
Turn, to realize the limit or releasing to separating brake connecting rod.
The present invention provides a kind of using the above-mentioned twin-lock structure for omnipotent breaker comprising breaker sheet
Body, the breaker body 2 are equipped with above-mentioned twin-lock structure 1, and the second latch hook member of the twin-lock structure and breaker sheet
Intracorporal separating brake connecting rod constitutes limit cooperation.
Embodiment is not construed as limitation of the present invention, but any based on spiritual improvements introduced of the invention, all should be
Within protection scope of the present invention.
