Abstract

The invention discloses a locking device for a breaker and a secondary plug-in. The locking device is arranged on one side of a secondary socket of the breaker and comprises a shell, a bent lock rod and a touch control block, wherein the shell is provided with a kidney-shaped hole, the bent lock rod penetrates through the kidney-shaped hole and is fixedly connected with the touch control block arranged in the shell, the touch control block is fixed into the shell in a rotatable mode and connected with a reset spring, the touch control block is provided with a rolling contact making contact with a protruding block arranged on the breaker, the protruding block and the rolling contact act to drive the bent lock rod to rotate to the position over the secondary plug-in and the breaker, and then the breaker is locked to the secondary plug-in. The locking device solves the problem that the breaker and the secondary plug-in are prone to disengagement and separation.

Description

A kind of circuit breaker secondary inserting piece locking device
Technical field
The present invention relates to a kind of circuit breaker secondary inserting piece locking device.
Background technology
Circuit breaker in described distribution box is pushed in distribution box by dolly and is inserted on described secondary inserting piece, circuit breaker is directly inserted on secondary inserting piece by traditional power distribution cabinet, between without any locking device, in use procedure, circuit breaker easily departs from secondary inserting piece, causes power distribution cabinet cisco unity malfunction.
Summary of the invention
The object of the present invention is to provide a kind of circuit breaker secondary inserting piece locking device fixed on by lock for circuit breaker on secondary inserting piece.
For reaching this object, the present invention by the following technical solutions:
A kind of circuit breaker secondary inserting piece locking device, be arranged on circuit breaker Secondary socket side, comprise housing, bending locking bar and touch controls block, described housing has waist-shaped hole, described bending locking bar is fixedly connected with the touch controls block be arranged in housing through described waist-shaped hole, described touch controls block is rotating to be fixed in described housing, and be connected with back-moving spring, described touch controls block is also provided with and the rolling contact of bump contact that arranges on circuit breaker.
Further, described touch controls block also comprises the locking bar installed surface being fixedly connected with bending locking bar, locking bar installed surface both sides are integrally fixed with side plate, described both sides side plate offers installing hole, on the cylindrical bar being enclosed within described housing internal fixtion that described installing hole coordinates, described left plate has also been wholely set rolling contact mounting panel, and described rolling contact is arranged on contact mounting panel end.
Further, described rolling contact comprises roller and connecting rod, and described connecting rod is integrally fixed on contact mounting panel end, and described roller housing is on described connecting rod.
Further, described bending locking bar is fixed by screws on described locking bar installed surface.
Beneficial effect of the present invention is: when described circuit breaker inserts in power distribution cabinet, the rolling contact of described circuit breaker secondary inserting piece locking device coordinates with the projection on circuit breaker and is pressed down by rolling contact, touch controls block is driven to rotate counterclockwise, the bending locking bar driven again moves on circuit breaker and fixes on secondary inserting piece by lock for circuit breaker, circuit breaker can not come off out from secondary inserting piece, ensures that distribution box normally works.
Accompanying drawing explanation
Fig. 1 is the structural representation of the circuit breaker secondary inserting piece locking device that the specific embodiment of the invention provides;
Fig. 2 is the front view of the circuit breaker secondary inserting piece locking device that the specific embodiment of the invention provides.
In figure, 1, housing; 11, waist-shaped hole; 2, bending locking bar; 31, locking bar mounting panel; 32, left and right side plate; 33, contact mounting panel; 34, connecting rod; 35, roller; 4, cylindrical bar; 5, back-moving spring; 6, screw; 7, secondary inserting piece.
Embodiment
Technical scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
As Fig. 1, shown in Fig. 2, described circuit breaker secondary inserting piece locking device, on the right side of the secondary inserting piece 7 being arranged on described distribution box, described circuit breaker secondary inserting piece locking device comprises housing 1, bending locking bar 2 and touch controls block, described touch controls block comprises locking bar mounting panel 31, left, right plate 32 and rolling contact, a described left side, right plate 32 offers installing hole, described installing hole be enclosed within be fixed on housing 1 internal fixtion cylindrical bar 4 on, be arranged in housing 1 by rotating for touch controls block, described housing 1 offers waist-shaped hole 11, described bending locking bar 2 is fixed on described locking bar mounting panel 31 through described waist-shaped hole 11 by screw 6, left plate is also connected with contact mounting panel 33, described rolling contact is arranged on contact mounting panel 33, the roller 35 that described rolling contact comprises the connecting rod 34 fixing with contact mounting panel 33 upper end one and is enclosed within described connecting rod 34, bending locking bar 2 is driven to turn to function circuit breaker realizing locking circuit breaker by the rolling contact projection effect arranged corresponding on circuit breaker, described locking bar mounting panel 31 is also connected with back-moving spring 5, the other end of described back-moving spring 5 is fixed on the below of housing 1.
When described circuit breaker secondary inserting piece locking device uses, the initial position of described bending locking bar 2 is positioned at the upside of secondary inserting piece 7, now circuit breaker to be advanced in described distribution box and to inject in secondary inserting piece 7, projection on circuit breaker and rolling contact contact action, rolling contact presses down, touch controls block is driven to rotate counterclockwise around described cylindrical bar 4, and drive the bending locking bar 2 be fixed on touch controls block to move down in waist-shaped hole 11, the bending keyed end of bending locking bar 2 is made to move to directly over secondary inserting piece 7, and lock for circuit breaker on secondary inserting piece 7 will be inserted in fix on secondary inserting piece 7, when circuit breaker need be unloaded, circuit breaker is pulled outwardly, projection on circuit breaker and described rolling contact depart from, described touch controls block rotates at the clockwise under influence of back-moving spring 5, drive bending locking bar 2 to reset and remove circuit breaker locking.
Below only describe the present invention with embodiment, but the present invention is not limited to above-mentioned size and outward appearance illustration, more should form any restriction of the present invention.As long as any improvement do the present invention or modification all belong within the protection range of the claims in the present invention opinion.
