Abstract
The utility model discloses a fixed vacuum circuit breaker with adjustable damping structure, including the base, the base both sides are fixed with the deflector respectively, and the spout has been seted up to the deflector opposite face, and slidable mounting has the vacuum circuit breaker body in the spout, base up end interval between the deflector is equipped with the multirow shock -absorbing spring, and shock -absorbing spring upper end suit is in the channel -section steel, and terminal surface under the vacuum circuit breaker body is fixed to the channel -section steel, and the draw -in groove has been offered respectively to every row of shock -absorbing spring group both sides, and slidable mounting has the backing plate in the draw -in groove, and the spacing piece of damping is installed to the backing plate upper end, is equipped with the clearance between spacing piece of damping and the vacuum circuit breaker body bottom surface. The utility model has the advantages of reasonable design, adjust the clearance between spacing piece of damping and the vacuum circuit breaker body bottom surface through the backing plate of changing different thickness, cooperate the ball of shock -absorbing spring, bolt and front end simultaneously, can effectively improve the resistance to shock in its working process, reduce the damage to self and service environment.
Description
Technical field:
This utility model relates to chopper, particularly relates to a kind of fixed vacuum breaker with adjustable vibration reduction structure.
Background technology:
Fixed vacuum breaker in the market is essentially all on the basis of being directly installed on channel-section steel, fixed vacuum breaker is when divide-shut brake action, the vibratory impulse produced is the biggest, on the one hand vacuum circuit breaker own components is produced certain damage, on the other hand vibration can produce impact to other devices in switch cubicle, therefore, fixed vacuum breaker is accomplished by the impact in view of its use environment when design, thus structure reasonable in design meets its use demand.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of fixed vacuum breaker with adjustable vibration reduction structure, reasonable in design, can be effectively improved the resistance to shock in its work process, to self and use environment reduction damage.
The technical solution of the utility model is as follows:
There is the fixed vacuum breaker of adjustable vibration reduction structure, it is characterised in that including that pedestal, described pedestal both sides are respectively fixed with guide plate, guide plate opposite face offers chute, is slidably fitted with vacuum circuit breaker body in chute；
Pedestal upper surface between described guide plate is interval with multiple rows of shock-absorbing spring, shock-absorbing spring upper end is sleeved in channel-section steel, channel-section steel is fixed on vacuum circuit breaker body lower surface, described often row shock-absorbing spring group both sides offer draw-in groove respectively, backing plate it is slidably fitted with in draw-in groove, backing plate upper end is provided with vibration damping banking stop, is provided with gap between vibration damping banking stop and vacuum circuit breaker body bottom surface.
The described fixed vacuum breaker with adjustable vibration reduction structure, it is characterised in that described vibration damping banking stop is crescent shape, the upper surface at vibration damping banking stop two ends is plane, and vibration damping banking stop is gradually reduced to two-end thickness from middle part.
The described fixed vacuum breaker with adjustable vibration reduction structure, it is characterised in that the lateral wall of described guide plate screws and is provided with bolt, and bolt front end is provided with ball, ball extend in chute and sphere contacts with vacuum circuit breaker body sidewall.
The utility model has the advantages that:
This utility model reasonable in design, it is adjusted the gap between vibration damping banking stop and vacuum circuit breaker body bottom surface by changing the backing plate of different-thickness, coordinate the ball of shock-absorbing spring, bolt and front end thereof simultaneously, the resistance to shock in its work process can be effectively improved, to self and use environment reduction damage.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of this utility model vibration damping banking stop.
Detailed description of the invention:
See accompanying drawing:
Having the fixed vacuum breaker of adjustable vibration reduction structure, including pedestal 1, pedestal 1 both sides are respectively fixed with guide plate 2, and guide plate 2 opposite face offers chute 3, is slidably fitted with vacuum circuit breaker body 4 in chute 3；
Pedestal upper surface between guide plate 2 is interval with multiple rows of shock-absorbing spring 5, shock-absorbing spring 5 upper end is sleeved in channel-section steel 6, channel-section steel 6 is fixed on vacuum circuit breaker body 4 lower surface, often row shock-absorbing spring group both sides offer draw-in groove 7 respectively, backing plate 8 it is slidably fitted with in draw-in groove 7, backing plate 8 upper end is provided with vibration damping banking stop 9, it is provided with gap 10 between vibration damping banking stop 9 and vacuum circuit breaker body 4 bottom surface, it is adjusted gap length between vibration damping banking stop and vacuum circuit breaker body bottom surface by changing different-thickness backing plate, thus controls the stroke of shock-absorbing spring 5.
Vibration damping banking stop 9 is in crescent shape, and the upper surface at vibration damping banking stop 9 two ends is plane, and vibration damping banking stop 9 is gradually reduced to two-end thickness from middle part.
The lateral wall of guide plate 2 screws and is provided with bolt 11, and bolt 11 front end is provided with ball 12, and ball 12 extend in chute and sphere contacts with vacuum circuit breaker body 4 sidewall, reduction frictional force.
