Abstract
The invention relates to a breaker interlocking mechanism which comprises a locking rod, a interlocking driver plate, a lock body with a locking dog and a reset spring. One end of the interlocking driver plate is hinged with one end of a locking rod, the other end of the interlocking driver plate is provided with a lock hole matched with the locking dog of the lock body, and the reset spring is connected with the interlocking driver plate. The breaker interlocking mechanism is characterized by comprising a linkage body which is of an integrated structure formed by bending a steel plate, and a fixed portion, a lock rod installing portion, a protruding portion and a lock body fixing portion are arranged on the linkage body, wherein the fixed portion is used for being connected with a handcart, the lock rod installing portion is used for installing the lock rod, the protruding portion is used for being hinged with the interlocking driver plate, the lock body fixing portion is used for installing the lock body, and the reset spring is connected with the lock rod installing portion. The breaker interlocking mechanism has the advantages of being simple in structure, convenient to assemble, low in cost, delicate and attractive in appearance, and low-carbon and environment-friendly in an assembling process.
Description
Technical field
The invention belongs to the controller switching equipment technical field, particularly relate to a kind of circuit breaker interlocking gear.
Background technology
The circuit breaker interlocking gear be for high-voltage switch cabinet breaker test, overhaul, when sending electricity and handcart advance and release that synchronous limiting circuit breaker closes a floodgate and a kind of device of separating brake.In the conventional circuit breaker interlocking gear, the members such as locking bar, chain driver plate, lock body and back-moving spring by erection of frames separately on handcart, support body is the variform part that is welded on the handcart with each Components Matching, there is following drawback in this circuit breaker interlocking gear in the process of installing: the part that forms interlocking gear is more, easily loses in the assembling process; Need a large amount of welding jobs in the interlocking gear installation process, this process can produce in large quantities carbon dioxide, not environmental protection, and welding sequence is complicated, cost is high; Mechanism's profile very complicated and attractive in appearance not.
Summary of the invention
The present invention for solve the technical problem that exists in the known technology provide a kind of simple in structure, easy to assembly, cost is low, profile is exquisite attractive in appearance, and the circuit breaker interlocking gear of assembling process low-carbon environment-friendly.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of circuit breaker interlocking gear, comprise locking bar, chain driver plate, lock body and back-moving spring with dead bolt, one end of described chain driver plate and an end of described locking bar are hinged, the other end of described chain driver plate is provided with the lockhole that can cooperate with the dead bolt of described lock body, described back-moving spring is connected with described chain driver plate, it is characterized in that: comprise chain body, described chain body is the integral structure that steel plate bending forms, has the fixed part that is connected for handcart on the described chain body, for the locking rod mounting part that described locking bar is installed, the lug boss that is used for hinged described chain driver plate, be used for installing the lock body fixed part of described lock body, described back-moving spring is connected with described locking rod mounting part.
The present invention can also adopt following technical scheme:
On the described locking bar roller is installed.
Advantage and good effect that the present invention has are: because the present invention adopts as above technical scheme, be that the supporting body of each member is to adopt whole plate bending to make the chain body of integral structure in the interlocking gear, have on the chain body for the private part that the members such as locking bar, chain driver plate, lock body and back-moving spring are installed, thereby greatly simplified the number of spare parts that consists of interlocking gear, and make linkage structure form the metastable integral body of structure, can effectively avoid part in mechanism's installation process, to lose; This linkage structure has saved traditional welding step in the process of assembling, not only the order assembling is more simple, cost is low, and has reduced the CO2 emission in the production process, is conducive to low-carbon environment-friendly.
