The pressure relief mechanism of the utility model supports pressure relief plate, the high temperature for discharging pressure relief plate by pressure relief opening using extension spring
High pressure gas impact is unlikely to deform damage when rising, to realize recycling；
The supporting mechanism of the utility model limits the support plate of rotation direction by being arranged above pressure relief plate, makes pressure relief plate
Support plate can be pushed when rising open, and stop it to drop back into pressure relief opening by support plate when pressure relief plate decline, so that pressure relief opening be made to keep
Opening state realizes the lasting exhaust cooling of power distribution cabinet, substantially increases the safety-type of power distribution cabinet.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the enlarged drawing in Fig. 1 at A；
Fig. 3 is the structural schematic diagram of the supporting mechanism.
Specific embodiment
As shown in Figure 1, a kind of automatic leakage die mould low-voltage distribution cabinet described in the utility model, including distribution cabinet body 1, distribution
Pressure relief opening 2 is offered on the top plate of cabinet body 1, the inside of pressure relief opening 2 is provided with pressure relief mechanism, and the outside of pressure relief opening 2 is provided with branch
Support mechanism.
Specifically, pressure relief mechanism includes 3, two mounting plates 4 of pressure relief plate and two groups of extension springs 5, pressure relief plate 3, which is covered on, to be let out
It presses on mouth 2, two mounting plates 4 are symmetricly set on the inner wall below 1 top plate of distribution cabinet body, and two groups of extension springs 5 are respectively set
On two mounting plates 4, the upper end of extension spring 5 connects pressure relief plate 3, the lower end connection plate 4 of extension spring 5.
As shown in Fig. 2, for the side wall of pressure relief opening 2 in step-like, the size on 2 top of pressure relief opening is greater than pressure relief plate in the present embodiment
3 size, the size of 2 lower part of pressure relief opening are less than the size of pressure relief plate 3, i.e., pressure relief plate 3 by 2 lower part of pressure relief opening side wall support.
Spring seal strip 6, when pressure relief plate 3 is covered on pressure relief opening 2,6 energy of elastic sealing strip are set on the side wall on 2 top of pressure relief opening
Enough improve the tightness that pressure relief opening 2 connects with pressure relief plate 3.
Supporting mechanism is divided into two groups, and is symmetricly set on the two sides of pressure relief opening 2, and supporting mechanism includes backboard 7, otic placode 8, branch
Fagging 9 and limit plate 10, backboard 7 are vertically arranged on the top plate of distribution cabinet body 1, and otic placode 8 is symmetricly set on the two sides of backboard 7,
The side of support plate 9 is rotatably arranged on otic placode 8 by pin 11, and the other side of support plate 9 extends to the top of pressure relief plate 3,
Limit plate 10 is horizontally set on backboard 7, and the lower section for being located at support plate 9 keeps 9 holding of support plate horizontal, as shown in Figure 3.Cause
This, 9 stress of support plate can be rotated up, but cannot be rotated down by the effect of limit plate 10.
