In the improvement technology, the dropout mode that a kind of connecting plate combines with semiaxis has appearred in this separating brake tripping mechanism, but the structure of this mode is complicated, is not applied preferably.
In addition, based on the applicant cam having been proposed--four connecting rods (pull bar) mechanism is as the operating mechanism that closes a floodgate, it has good rigidly, in light weight, flexible movements are rapid, reliability is high advantage, for this reason, for cooperating improvement to the combined floodgate operating mechanism, improve the overall performance of circuit breaker, the applicant thinks necessary traditional brake separating mechanism is improved.
Summary of the invention
Goal of the invention of the present utility model is to overcome the deficiencies in the prior art, provides a kind of little to snap close axle impulsive force, improves the reliability of separating brake and the indoor HVAC vacuum circuit breaker separating brake tripping mechanism that effectively increases the service life.
Goal of the invention of the present utility model is achieved in that a kind of indoor HVAC vacuum circuit breaker separating brake tripping mechanism, comprise and to drive on/off switch main shaft linkage that rotates and the separating brake snap close axle of being located on the frame, connecting lever in the linkage is fixed on the on/off switch main shaft, separating brake snap close axle is the semiaxis structure, it is characterized in that: separating brake jam plate assembly is housed on the described frame, one end roof pressure of separating brake jam plate assembly is on the real semiaxis of separating brake snap close axle, along with the rotation of separating brake snap close axle, separating brake jam plate assembly can be threaded off from real semiaxis; The other end roof pressure of separating brake jam plate assembly is on the connecting lever of linkage.
Described separating brake jam plate assembly comprises separating brake locking board and roof pressure the separating brake one-level locking board on connecting lever of roof pressure on the real semiaxis of separating brake snap close axle, separating brake one-level locking board hinge is installed on the separating brake locking board, and separating brake one-level locking board can rotate on the separating brake locking board around the hinge tie point.
Described separating brake locking board is provided with and is used for the back-moving spring that the rotation of separating brake one-level locking board resets.
Described separating brake one-level locking board roof pressure is at the end of connecting lever, and the end of connecting lever is equipped with the separating brake roller that matches with separating brake one-level locking board.
The utility model improves the indoor HVAC vacuum circuit breaker separating brake tripping mechanism of prior art, between the linkage of separating brake snap close axle and the rotation of driving on/off switch main shaft, be provided with the separating brake jam plate assembly that matches, when circuit breaker carries out sub-switching operation, the overtravel spring of breaker open operation and the reverse impact power of tripping spring can be directly to not being applied on the separating brake snap close semiaxis, in addition, the dropout semiaxis is by the separating brake actuating of separating brake jam plate assembly control circuit breaker, reduced the dropout merit, improved the reliability of machine dropout, the useful life that helps improving circuit breaker with separating brake.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
With reference to the accompanying drawings shown in 1, indoor HVAC vacuum circuit breaker separating brake tripping mechanism of the present utility model, it comprises linkage 2 and the separating brake snap close axle of being located on the frame 34, linkage 2 is four connecting rods and can drives 1 rotation of on/off switch main shaft, connecting lever 21 in the linkage 2 is fixed on the on/off switch main shaft 1, and its concrete fixing point is the central part of connecting lever 21; Separating brake snap close axle 4 is the semiaxis structure.For overcoming the deficiencies in the prior art part, the utility model is equipped with separating brake jam plate assembly on described frame 3, one end roof pressure of separating brake jam plate assembly is on the real semiaxis of separating brake snap close axle 4, and along with the rotation of separating brake snap close axle 4, separating brake jam plate assembly can be threaded off from real semiaxis; The other end roof pressure of separating brake jam plate assembly is on the connecting lever 21 of linkage 2.After breaker switching-on operation is finished, the overtravel spring and the tripping spring that are connected with on/off switch main shaft 1 also are elongated, finish similar thermal energy storage process, at this moment, be in the on/off switch main shaft 1 of closing position owing to be subjected to the tension of overtravel spring and tripping spring, the trend of resetting is arranged, and just the connecting lever 21 of linkage 2 is sincere firmly by separating brake jam plate assembly roof pressure.
During this time, separating brake jam plate assembly comprises separating brake locking board 5 and roof pressure the separating brake one-level locking board 6 on connecting lever 21 of roof pressure on separating brake snap close axle 4 real semiaxis, separating brake one-level locking board 6 hinges are installed on the separating brake locking board 5, and separating brake one-level locking board 6 can rotate on separating brake locking board 5 around the hinge tie point.And separating brake one-level locking board 6 roof pressures are at the end of connecting lever 21, and the end of connecting lever 21 is equipped with the separating brake roller 8 that matches with separating brake one-level locking board 6, and separating brake roller 8 can reduce the contact friction between connecting lever 21 and the separating brake one-level locking board 6.
