Description
Technical field
The utility model relates to a kind of breakers, latch mounting bracket more particularly, to a kind of breaker.
Background technique
Breaker is the electric current referred to close, carry and cut-off under normal loop condition and can close, when defined
Interior carrying and the switching device for cut-offfing the electric current under abnormal loop condition.Breaker can be used to distribute electric energy, infrequently open
Dynamic asynchronous motor protects the implementations such as power circuit and motor, when serious overload or short circuit and under-voltage occurs in they
Etc. failures when can automatic shutdown circuit, function is equivalent to Fuse switch and crosses the combination of underheat relay etc..
Currently, being equipped with big lock and small lock, specific mounting means in the lock mounting bracket of existing breaker
Are as follows: draw bar is fixed on small lock, and small lock and small torsional spring and big lock pass through two axis with big torsional spring respectively and be assemblied in
It latches in mounting bracket.There are the following problems when in use for this lock mounting bracket: draw bar needs to guarantee its concentricity,
The hole concentricity of small lock cooperation related to lock mounting bracket is required to get well, relevant shaft hole matching will be suitable etc., it is several layers of
The cooperation of concentricity requirement in the case where to(for) single part is just higher, wherein the related matching hole of lock mounting bracket will expire
Sufficient concentricity difficulty is maximum, because lock mounting bracket bending part and screw bearing are too long with a distance from relevant hole, it is difficult to ensure that.Phase
There is also problem above at the big lock answered.
Utility model content
The purpose of this utility model is to provide a kind of breakers to latch mounting bracket, to solve breaker in the prior art
There is lock and corresponding axis hole concentricity difference in lock mounting bracket.
For this purpose, the utility model uses following technical scheme:
A kind of breaker lock mounting bracket comprising mounting bracket, small lock, big lock and draw bar, wherein described
Mounting bracket includes two blocks of side plates of parallel interval setting, and the small lock is fixedly connected by the first fixing axle with draw bar,
The small lock is set between two blocks of side plates with being able to rotate by the second fixing axle, and the big lock is located at the small lock
Lower section is arranged between two blocks of side plates with being able to rotate by third fixing axle, and small torsional spring and big torsional spring are assemblied in second respectively and consolidate
On dead axle and third fixing axle, connecting plate, the company are welded with below the big lock between two blocks of side plates
The concentricity latched when fishplate bar welds with small lock and greatly is positioned.
Particularly, two blocks of side plates are extended with a bending plate inwardly, and the connecting plate is fixedly welded on two foldings
The outside of bent plate.
Particularly, correspondence offers small lock pilot hole between the top of two blocks of side plates, second fixing axle
Both ends are fixed in small lock pilot hole.
Particularly, corresponding between two blocks of side plates to offer big lock pilot hole, the both ends of the third fixing axle are solid
It is latched in pilot hole due to big, and the third fixing axle is located at the lower section of the second fixing axle.
The beneficial effects of the utility model are that the breaker latches two blocks of side plates of mounting bracket compared with prior art
Between be fixedly connected by connecting plate, positioned when connecting plate welds with small lock and the concentricity that latches greatly, to protect
The concentricity of the big lock of card and small lock later period assembly.The reliability of breaker can not only be improved；And reduce pilot hole
Difficulty of processing.
