As shown in Figure 3: described support 4 comprises the first support 4-1 and the second support 4-2; The said first support 4-1 and the second support 4-2 are separately positioned on the both sides of pressure relief opening; And the first support 4-1 is respectively arranged with axis hole on the side relative with the second support 4-2; Trap 3 is provided with the axle that matches with axis hole, and said trap 3 is hinged on the first support 4-1, the second support 4-2 through axle; Said stopping means is a limiting plate 2 as shown in Figure 3, and limiting plate 2 is fixed on the support 4.
As shown in Figure 4: said stopping means also can be the first torsion spring A, the second torsion spring B, and the described first torsion spring A and the second torsion spring B are separately positioned in the axis hole of the first support 4-1 and the second support 4-2, and with trap 3 on the axle be connected.
Embodiment two:
Like Fig. 5, shown in Figure 6: the utility model comprises substrate 1, stopping means, trap 3 and support 4, and said substrate 1 is used to be arranged on the switchgear cabinet, and substrate 1 is provided with pressure relief opening, makes that the switch cabinet is inner to be communicated with space outerpace; Said support 4 is fixed on the substrate 1, and trap 3 flexibly connects with support 4, and trap 3 is positioned on the pressure relief opening, is used to realize covering or the unlatching to pressure relief opening; Said stopping means is arranged on the support 4, is used to limit the opening angle of trap.
Present embodiment medium-height trestle 4 and trap 3 and the connected mode of stopping means and the stopping means that is adopted and embodiment one are identical.
When the embodiment one of the utility model uses with embodiment two, all substrate 1 directly is installed on the switchgear cabinet and get final product, the air pressure of switchgear cabinet inside equates that with external atmosphere pressure trap 3 can not opened under the normal condition; In case switchgear cabinet pressure inside is excessive, because inside and outside pressure is different, the inner pressure of cabinet can back down trap 3, discharges the cabinet pressure inside, guarantees the safety of switchgear.And because trap 3 is connected with support 4, so trap 3 do not have the situation generation that flies out and hurt sb.'s feelings, and pressure has discharged afterwards that trap 3 can return to normal state; Again owing on support 4, be provided with stopping means (limiting plate 2 or torsion spring); Will limit the opening angle of trap 3 like this; The maximum opening angle of trap 3 is set at 90 °, guarantees that having discharged back trap 3 in the cabinet internal pressure can return to normal condition.
Embodiment three:
As shown in Figure 7: the utility model comprises substrate 1, stopping means, trap 3 and support 4, and said substrate 1 is used to be arranged on the switchgear cabinet, and substrate 1 is provided with pressure relief opening, makes that the switch cabinet is inner to be communicated with space outerpace; Said support 4 is fixed on the substrate 1, and trap 3 flexibly connects with support 4, is used to realize covering or the unlatching to pressure relief opening; Said stopping means is arranged on the support 4, is used to limit the opening degree of trap.
Said support 4 is not for to comprise cuboid upper and lower surfaces, hollow, and the bottom of support 4 also is provided with base 6, is provided with aperture on four sides of support 4; Pressure relief opening on the said substrate 1 is arranged on the inside of support 4, and trap 3 covers on the support 4, and said trap 3 flexibly connects through stopping means and support 4.
The said stopping means of present embodiment comprises four articulated link chains; Two articulated link chain 5-1 and 5-2 have been shown among the figure, have also had unshowned and articulated link chain 5-1,5-2 to be symmetrical set two articulated link chains in ground; Described four articulated link chains connect the edge of trap 3 and the base 6 of support 4 symmetrically, and the drift of four articulated link chains is all greater than the distance between trap 3 and support 4 bases.
