It encloses.
Also referring to Fig. 1,2 and 3, Fig. 1 is the cabinet body of inflatable switch cabinet of the present invention and the structural representation of interlocking mechanism
Figure, Fig. 2 are the cabinet door structure schematic diagram of inflatable switch cabinet of the present invention, and Fig. 3 is the fastener of inflatable switch cabinet of the present invention
Structural schematic diagram.The inflatable switch cabinet includes cabinet body 1 and assembles the cabinet door 2 to form accommodation space with the cabinet body 1.It is female
Line, cable, breaker and various electric meters etc. can be contained in the accommodation space.
The interlocking mechanism 10 for being fixed on the cabinet body 1 is equipped in the cabinet body 1, the interlocking mechanism 10 includes rotating member
100 and fastener 101.The cabinet door 2 is equipped with lockhole 20, and described 101 one end of fastener and the rotating member 100 cooperate, separately
One end and the lockhole 20 cooperate.
The rotating member 100 includes shaft 1000 and the turntable 1001 for being fixed on the shaft 1000.The shaft 1000
Be equipped with the nut portion 1002 that cross section is in regular hexagon, in this way, can by the cooperation in spanner and the nut portion 1002 come
Rotate the shaft 1000.The turntable 1001 is equipped with bayonet 1003.
The fastener 101 includes lock rod guiding part 1010, locking bar 1011, buckle 1012 and elastic component 1013.It is described
Lock rod guiding part 1010 is sheathed on the locking bar 1011, the locking bar 1011 in the lock rod guiding part 1010 along straight line back and forth
It is mobile.
The elastic component 1013 cooperates with the locking bar 1011 to provide elastic-restoring force, and described 1013 one end of elastic component is solid
Due to the locking bar 1011, the other end is fixed on the lock rod guiding part 1010, in a preferred embodiment, the elastic component
1013 be helical spring, and the elastic component 1013 is sheathed on the locking bar 1011, and certainly, the elastic component 1013 can also be it
The spring of its shape provides the function of elastic-restoring force as long as can play for the locking bar 1011, then ought to belong to this
Within the protection scope of invention.
The buckle 1012 is fixed on the locking bar 1011 and for cooperating with the bayonet 1003, in preferred embodiment party
In formula, the buckle 1012 is pin.
The inflatable switch cabinet further includes the support frame 3 for being fixed on the cabinet body 1, and the lock rod guiding part 1010 is fixed
In support frame as described above 3.
Again together refering to Fig. 4, Fig. 4 is the cabinet door locking and unlocking method of inflatable switch cabinet of the present invention.The present invention also mentions
The cabinet door locking and unlocking method for having supplied a kind of inflatable switch cabinet according to, include the following steps：
S1, when the inflatable switch cabinet is powered, rotate the rotating member 100, the buckle 1012 be sticked in institute
It states in bayonet 1003, the locking bar 1011 cooperates with the lockhole 20, and the cabinet door 2 is locked；
Specifically, making the bayonet 1003 be directed at the buckle 1012, the locking bar by rotating the rotating member 100
1011 move under the action of the elastic-restoring force of the elastic component 1013, so that the buckle 1012 be pushed to be arranged in the card
In mouth 1003, while the locking bar 1011 one end and the lockhole 20 far from the buckle 1012 cooperate, due to the buckle
1012 are arranged in the bayonet 1003, therefore the locking bar 1011 can not move, thus when ensure that energization, the cabinet door 2
Locking.
S2, when inflatable switch cabinet power-off, the buckle 1012 is removed out of described bayonet 1003, institute is disengaged
The cooperation for stating locking bar 1011 Yu the lockhole 20, rotates the rotating member 100, and the cabinet door 2 unlocks.
Specifically, first moving the locking bar 1011 buckle 1012 is come out out of described bayonet 1003, then turns
Moving the rotating member 100 cooperate the buckle 1012 can not with the bayonet 1003, and the locking bar 1012 is in the elasticity
The outer peripheral edge of the rotating member 100 is connected under the action of the elastic-restoring force of part 1013, at this point, the locking bar 1011 can not be with
The lockhole 20 cooperates, and therefore, the cabinet door 2 keeps unlocked state.
Compared with the relevant technologies, inflatable switch cabinet provided by the invention is had the advantages that：1, when being powered, in institute
It states after locking bar 1011 is inserted into the lockhole 20 of the cabinet door 2, passes through the cooperation of the buckle 1012 and the bayonet 1003, protect
Demonstrate,proving the cabinet door 2 can not open, it is ensured that the personal safety of operator；
2, cooperated using the locking bar 1012 and the lockhole 20, structure is simple, convenient for disassembly and assembly, reliable performance；
3, cooperated by the buckle 1012 with the bayonet, the locking bar 1011 is effectively ensured and is being inserted into the lockhole 20
After will not move.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
