Abstract
The utility model discloses an opening-prevention mechanism of a universal breaker. The opening-prevention mechanism comprises a connecting rod, a pad, a positioning shaft pin, a shaft sleeve, a pull rod, a positioning shaft sleeve, and a support. The opening-prevention mechanism is characterized in that the pull rod is fixed on the connecting rod through the pad; the shaft sleeve is mounted on the support through a screw; the positioning shaft pin is arranged on the pull rod; the positioning shaft sleeve is arranged inside the shaft sleeve; and the shaft sleeve together with the positioning shaft sleeve and a spring are sleeved on the pull rod. The connecting rod is in a right-angle flat rod structure and a kidney slot is arranged on the connecting rod. When the opening-prevention mechanism is in operation, the movement track of the connecting rod can cover the movement path of an opening release rod, and the connecting rod can prop up the opening release rod of the breaker, so that the opening motion of the breaker can be effectively prevented.
Description
Technical field
The utility model relates to a kind of anti-brake separating mechanism of omnipotent breaker, belongs to low-voltage electrical apparatus manufacturing technology field.
Background technology
When omnipotent breaker is used for some Code in Hazardous Special Locations, such as distribution system on the naval vessel etc., because special environment for use, require circuit breaker running into overload, short circuit, decompression, under-voltage, impact etc. in emergency circumstances, do not disconnect, still can holding circuit power continuously, to satisfy the specific (special) requirements of the Code in Hazardous Special Locations such as naval vessel.For satisfying this specific (special) requirements, at present, this mechanism designed on the industry normally guarantees that by a plurality of link gearings breaker mechanism dropout semiaxis can't move to realize what it did not disconnect.This anti-brake separating mechanism of circuit breaker that is consisted of by a plurality of link gearings, not only structure is comparatively complicated, and in actual applications, requires the secondary necessary flexibility and reliability of each link transmission, otherwise stuck phenomenon will in operating process, occur, thereby cause this failure mechanisms.
Summary of the invention
For the problem that above-mentioned technology exists, the purpose of this utility model provides the anti-brake separating mechanism of a kind of omnipotent breaker simple in structure, easy and simple to handle, dependable performance.
For achieving the above object, the utility model has been taked following technical scheme:
A kind of omnipotent breaker described in the utility model is prevented brake separating mechanism, includes connecting rod, pad, location axle pin, axle sleeve, pull bar, positioning shaft sleeve, support, it is characterized in that pull bar is fixed on connecting rod by pad; Axle sleeve is rack-mount by screw, and location axle pin is arranged on the pull bar; Positioning shaft sleeve is arranged in the axle sleeve, and is sleeved on the pull bar with positioning shaft sleeve and spring.The rectangular flat bar structure of described connecting rod on connecting rod, is provided with kidney slot.
After the utility model is assemblied in circuit breaker, because the movement locus of connecting rod can cover the motion path of separating brake dropout rod, namely when the motion of operation pull bar drivening rod, the separating brake dropout rod of circuit breaker can be propped up, thereby the separating brake that can effectively prevent circuit breaker moves.

Embodiment
Below in conjunction with accompanying drawing, specific embodiments of the present utility model is further described in detail, but is not restriction to the utility model protection range.
A kind of omnipotent breaker described in the utility model is prevented brake separating mechanism, includes connecting rod 1, pad 2, location axle pin 5, axle sleeve 6, pull bar 7, positioning shaft sleeve 8, support 9, it is characterized in that pull bar 7 is fixed on connecting rod 1 by pad 2; Axle sleeve 6 is installed on the support 9 by screw 4, and location axle pin 5 is arranged on the pull bar 7; Positioning shaft sleeve 8 is arranged in the axle sleeve 6, and is sleeved on the pull bar 7 with positioning shaft sleeve 8 and spring 3.Described connecting rod 1 rectangular flat bar structure on connecting rod 1, is provided with kidney slot.
Working method of the present utility model is achieved like this:
The utility model is installed on the breaker mechanism 14 with screw 13, and screw 12 is made support and the guiding parts of connecting rod 1.When location axle pin 5 was in position shown in Figure 2 on the pull bar 7, breaker open operation dropout rod 11 was not propped up, and omnipotent breaker can normally carry out sub-switching operation.
After omnipotent breaker carries out closing operation, pull bar 7 is rotated to an angle, location axle pin 5 on it will snap in the draw-in groove of positioning shaft sleeve 8, restoring force effect by spring 3, connecting rod 1 will move along the direction that screw 12 limits, and make connecting rod 1 be in separating brake and thread off between rod 11 and the supporting plate 10.As shown in Figure 3, when carrying out sub-switching operation, because supporting plate 10 supports connecting rod 1, simultaneously again because the position-limiting action of screw 12, the separating brake rod 11 of threading off can't move downward, thereby effectively prevent the omnipotent breaker sub-switching operation of threading off.
The utility model can effectively prevent the sub-switching operation of omnipotent breaker, and has characteristics simple in structure, easy and simple to handle, dependable performance.
