Abstract
The utility model discloses a high -rise building cubical switchboard with effect is sealed to rigidity, including the cabinet body and end cover, end cover edge with prolong the limit and be 90 degrees and be connected, extension limit surface is provided with the sealing strip, the sealing strip is middle part hunch -up shape, is close to one side and extension limit fixed connection of end cover, and the other end is the free end, be provided with the spring in the inboard cavity in sealing strip middle part hunch -up position, outside the overlapping of spring has the rubber pad, rubber pad and the coaxial setting of spring and axial direction and extension limit are 90 degrees, and under natural state, extension limit surface is greater than to the distance of sealing strip hunch -up position peak and prolongs the distance of limit surface to the internal side of cabinet. Owing to increased the metal seal limit, its is longe -lived, and is durable, is difficult for the oxidation, establishes the spring in the while, makes it have lasting sealing load, difficult decay.
Description
Technical field
This utility model relates to electric circuit protection equipment field, particularly relates to contactor protection cabinet, specifically, is a kind of skyscraper switch cubicle with rigid seal effect.
Background technology
The low-tension switch cabinet used in skyscraper is mainly used in distribution and electric energy conversion, and its sealing requirements is higher.Existing power distribution cabinet mainly uses the mode of fluting, arranges the structures such as sealing joint strip, seal power distribution cabinet edge with cabinet door structure in groove.Owing to, in power distribution cabinet radiation processes, sealing joint strip can be made gradually to lose efficacy, its sealing property therefore can be affected.
Utility model content
This utility model technical issues that need to address are: the fastness solving to seal in prior art distribution switchgear cabinet is the highest, the unabiding problem of sealing.
This utility model is achieved through the following technical solutions:
A kind of skyscraper switch cubicle with rigid seal effect, including cabinet and end cap, described end cap edge is 90 degree with prolongation limit and is connected, described prolongation limit outer surface is provided with sealing strip, described sealing strip is to arch upward shape in middle part, fix with prolongation limit near the side of end cap and be connected, the other end is free end, it is provided with spring in the position inner chambers that arches upward in the middle part of described sealing strip, rubber blanket it is cased with outside spring, described rubber blanket and spring are coaxially disposed and axial direction is 90 degree with prolongation limit, in its natural state, extend limit outer surface and arch upward the distance of position peak more than the distance inside prolongation limit outer surface to cabinet to sealing strip.
Preferably, the outlying location-plate that is fixedly installed outside one end of end cap of described prolongation, described location-plate is provided with groove towards the side of end cap, and the free end of described sealing strip is stuck in described groove.
Preferably, the thickness of described location-plate is more than the thickness on prolongation limit, less than the distance inside prolongation limit outer surface to cabinet.
Preferably, described sealing strip mode with bolts is fixed on the outer surface extending limit.
Preferably, during the material of described sealing strip is copper, aluminum, aluminium alloy any one.
Preferably, described end cap, prolongation limit and location-plate are formed in one.
This utility model compared with prior art, has the following advantages and beneficial effect:
(1) this utility model is by being provided with the sealing strip of arch, utilize the metamorphosis of spring and rubber blanket, sealing strip is made to be formed seal with sealing strip inwall and prolongation limit outer wall with cabinet inwall, rubber blanket, thus realize the sealing of end cap and cabinet, owing to adding metal sealing limit, its life-span is long, durable, the most oxidizable, simultaneously in set spring, make it have lasting seal pressure, be difficult to decay.
(2) owing to setting up arch sealing strip, its amplitude is conducive to end cap to enter cabinet smoothly when switch, enhances operability.

Fig. 1 is cross-sectional view of the present utility model；
Wherein 1-cabinet；2-end cap；3-extends limit；4-location-plate；5-groove；6-sealing strip；7-free end；8-cavity；9-spring；10-rubber blanket.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment:
A kind of skyscraper switch cubicle with rigid seal effect, including cabinet 1 and end cap 2, described end cap 2 edge is connected in 90 degree with extending limit 3, described prolongation limit 3 outer surface is provided with sealing strip 6, described sealing strip 6 arches upward in middle part shape, fix with prolongation limit 3 near the side of end cap 2 and be connected, the other end is free end 7, it is provided with spring 9 in the position inner chambers 8 that arches upward in the middle part of described sealing strip 6, spring 9 is outside is cased with rubber blanket 10, described rubber blanket 10 and spring 9 be coaxially disposed and axial direction with prolongation limit 3 in 90 degree, in its natural state, extend limit 3 outer surface and arch upward the distance of position peak more than the distance inside prolongation limit 3 outer surface to cabinet 1 to sealing strip 6.
In order to preferably make coordinating of sealing strip 6 and cabinet 1, in embodiment, described prolongation limit 3 is away from being fixedly installed location-plate 4 outside one end of end cap, and described location-plate 4 is provided with groove 5 towards the side of end cap 2, and the free end 7 of described sealing strip 6 is stuck in described groove 5.
Further, the thickness of described location-plate 4 is more than the thickness on prolongation limit 3, less than the distance inside prolongation limit 3 outer surface to cabinet 1.
It is further preferred that described sealing strip 6 mode with bolts is fixed on the outer surface extending limit 3.
It is further preferred that the material of described sealing strip 6 be in copper, aluminum, aluminium alloy any one.
It is further preferred that described end cap 2, prolongation limit 3 and location-plate 4 are formed in one.
For the deflection having rubber blanket 10 described in enough space to have, it is further preferred that the position inner space volume more than described rubber blanket 10 that arches upward in the middle part of described sealing strip 6.
Operation principle:
When end cap 2 be not embedded into cabinet 1 be in open mode time, under the elastic reaction of spring 9 and rubber blanket 10, the free end 7 of sealing strip 6 against groove 5 away from extend limit 3 side；When end cap 2 embed cabinet 1 be closed time, due to by cabinet 1 inwall to the extruding outside sealing strip 6, the free end 7 of sealing strip 6 is close to the outer surface extending limit 3, rubber blanket 10 is squeezed and is close to extend the outer surface on limit 3, simultaneously because deformable squeeze cavity 8, make cavity 8 and extraneous isolation；Sealing strip 6 is close to the inwall of cabinet 1 under pressure, it is achieved realize seal isolation inside and outside cabinet 1.
The above; it it is only preferred embodiment of the present utility model; not this utility model is done any pro forma restriction, every according to technical spirit of the present utility model, above example is made any simple modification, equivalent variations, within each falling within protection domain of the present utility model.
