Description
Technical field
This utility model relates to electric power mechanism box technology field, a kind of circuit breaker mechanism case with supporting plate.
Background technology
The cabinet door that is mainly designed to of existing electric power mechanism cabinet door makes cabinet door realize switch by door-hinge locating rotation, by
In electric power mechanism, cabinet door is heavier, the widest so that cabinet door shaft distortion, to such an extent as to the phenomenon damaged happens occasionally, and have impact on
The sealing property of cupboard, the threat potential to the security presence of Field Force.
Summary of the invention
The purpose of this utility model is to provide a kind of novel circuit breaker mechanism case, changes existing circuit breaker case
Enter, effectively prevent the deformation of casing door-hinge, keep the good seal performance of circuit breaker mechanism case.
This utility model adopts the following technical scheme that realization:
A kind of circuit breaker mechanism case, including casing, chamber door is installed by rotating shaft in described casing front；Described tank floor is pacified
Dress supporting plate, between small end and the big end of described supporting plate, gradual change type is formed, and the big end of described supporting plate is positioned at rotating shaft side；Described chamber door and
Supporting plate CONTACT WITH FRICTION.
Increase the supporting plate of jacking chamber door in electric power mechanism tank floor, share casing and visit the part weight of bearing load chamber door
Amount, is reduced or eliminated chamber door rotating shaft deformation, the generation of damage phenomenon.So, increase jacking chamber door in electric power mechanism tank floor
Supporting plate so that chamber door is the most in frictional contact, and during switch gate, cabinet door and supporting plate keep sliding friction, in order to avoid chamber door with
The frictional force of supporting plate is excessive, the door-hinge of cabinet door should have small up and down and the function of left and right adjusting, because of chamber door closedown time relatively
Its opening time is many, so being designed as big than when opening of supporting plate and the contact area of chamber door when closing, then supporting plate
Big end be positioned at rotating shaft side, when chamber door is closed, supporting plate can be good at sharing the weight of chamber door, it is ensured that door-hinge is in the big portion closed
Stress is minimum in timesharing, also ensures that flexible after unlatching of door.
This novel breaker mechanism chamber door is welded on the downside of circuit breaker mechanism case doorframe with solid by the supporting plate of jacking cabinet door
That determines mechanism's chamber door does the door-hinge composition finely tuned.During use, continuous guiding mechanism every axle fastening screw so that switch gate
Action can complete, and reduces the stress of door-hinge as far as possible, it is ensured that the using effect of cabinet door and life-span.
The advantage of the breaker mechanism box door device with guide rail is as follows:
1, stress and the stress time of door-hinge are reduced.
2, after the mechanism's chamber door life-time service after improving, door-hinge portion will not occur substantially to deform, it is ensured that the sealing effect of chamber door
Really.
This utility model is reasonable in design, installs supporting plate additional on existing circuit breaker case, effectively shares the chamber door weight of rotating shaft
Amount, extends the service life of rotating shaft, it is ensured that the sealing property of casing, reduces the renewal cost of product.
Accompanying drawing explanation
Fig. 1 represents that chamber door opens front view.
Fig. 2 represents that chamber door opens top view.
In figure, 1-casing, 2-chamber door, 3-rotating shaft, 4-supporting plate, 5-handle.
Detailed description of the invention
Below in conjunction with the accompanying drawings specific embodiment of the utility model is described in detail.
A kind of circuit breaker mechanism case, as shown in Figure 1, 2, including casing 1, chamber door is installed by rotating shaft 3 in described casing 1 front
2, rotating shaft is switch hinge；Described casing 1 underrun welding manner installs supporting plate 4, the small end of described supporting plate 4 and big end
Between gradual change type formed, the big end of described supporting plate 4 is positioned at the big end of rotating shaft side, i.e. supporting plate and is positioned at below rotating shaft, and at the bottom of prominent casing
A face part, when chamber door is opened, the big end of supporting plate also is able to the weight of portions thereof chamber door；Described chamber door 2 and supporting plate 4 rub
Contact, it is ensured that supporting plate can share the moiety by weight of chamber door, is not result in the deformed damaged of rotating shaft.
During use, after chamber door is assembled, constantly adjust door-hinge fixed screw by switch gate experiment, to being easier to switch
During cabinet door.Increase the supporting plate of jacking cabinet door at electric power mechanism case, supporting plate sliding friction following with chamber door contacts.
It should be noted last that, above example is only in order to illustrate the technical solution of the utility model and unrestricted, to the greatest extent
Pipe has been described in detail with reference to this utility model embodiment, it will be understood by those within the art that, new to this practicality
The technical scheme of type is modified or equivalent, without departure from the spirit and scope of the technical solution of the utility model, its
All should contain in claims.
Claims (2)
1. a circuit breaker mechanism case, including casing (1), chamber door (2) is installed by rotating shaft (3) in described casing (1) front；It is special
