Embodiment
Below in conjunction with an embodiment of accompanying drawing 1-8 explanation utility model, the utility model is not only limited to the description of following execution mode.The locking device of circuit breaker of the present utility model is not only applicable to circuit breaker, also applicable to fields such as isolating switch, on-load switches.
As shown in Figure 1, the locking device of circuit breaker is made up of operating mechanism and latch mechanism.Operating mechanism comprises a support 1 that is used to install all or part of operating mechanism of circuit breaker inside, and support 1 can be the part of Shell of circuit breaker, also can be independent of outside the housing.Detain 4 again for one, by detaining on axle 3 mounting brackets 1, a snap close 5 is installed on the support 1 by snap close axle 2 again, also be provided with the tripping 6 of the work that matches with snap close 5 in the operating mechanism, after detaining 4 rotations again, snap close 5 releases trigger tripping 6 springs and make the release of whole operation mechanism.
Be installed in latch mechanism on the case for circuit breaker 9 of latch mechanism and comprise that one is installed in the lock core 8 on the case for circuit breaker 9 and lock core 8 is fastened on bullet pad 10 and fastening bung flange 11 on the case for circuit breaker 9,12, one of rotation that are enclosed within on the lock core is installed in sliding shoe 13 on the rotatable lamella 12 by fixed head 14 and trip bolt 15.On described trip bolt 15, also be provided with a sealing plug 16 that is used to seal trip bolt 15.Key 7 can control lock mechanism.
Case for circuit breaker 9 concrete structures as shown in Figure 4, positive 91 1 sides of case for circuit breaker 9 have a circular hole 92, it is to be used for installing lock core 8, and place's groove 93 is arranged on circular hole 92 edges, lock core 8 can be fixed on initial condition position when rotating by groove 93.
Sliding shoe 13 concrete structures as shown in Figure 8, sliding shoe 13 is hollow spill side bodies, the centre is provided with a runway shape circular hole 131, near circular hole 131 rear and front ends one crossbeam 132 and 133 are arranged respectively, when rotatable lamella 12 comes back rotation, rotatable lamella summit 122 and 123 promotes slide block crossbeam 132 and 133 respectively, and sliding shoe 13 produces horizontal linear and moves forward and backward under rotatable lamella 12 promotes; Be provided with in sliding shoe 13 1 ends can to spur when " 7 " font drag hook 134,134 is moved to a certain position and detain side 4a again and rotate, detain again 4 rotate after, snap close 5 releases trigger tripping 6 springs and make the structure release of whole operation mechanism.
By the technical scheme of the above embodiments, latch mechanism 4 rotates the release of trigger action mechanism can driving buckleing again on the operating mechanism under the rotation of key 7.The following describes the locking and unlocking operating process of latch mechanism:
1. locking
