Specific embodiment
Shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, a kind of earthing switch of fixed switching cabinet and cable chamber door are mechanical
Blocking mechanism, including cabinet body 1 are equipped with antetheca 11 before cabinet body 1, and rear wall 12 is equipped with behind cabinet body, is equipped with cable vault in cabinet body 1
10, earthing switch is installed, earthing switch is equipped with earthing switch motive spindle 2, earthing switch motive spindle 2 in cable vault 10
It is mounted on 10 the inside of cable vault, is equipped with earthing switch operation handle 3,3 He of earthing switch operation handle outside the antetheca 11 of cabinet body
Transmission mechanism 31 is equipped between earthing switch motive spindle 2；The rear wall 12 of cabinet body can be movably installed with cable chamber door 4 with being opened flat,
Cable chamber door 4 is equipped with strike plate 5, and cabinet body rear wall 12 is fixedly installed with lockset bracket 6, trisquare shape is equipped on lockset bracket 6
Deadlock lever 7, the deadlock lever 7 of trisquare shape includes the deadlock lever first segment 71 being successively linked together, deadlock lever second segment 72, locking
Bar third section 73(is as shown in Figure 7), deadlock lever second segment 72 is respectively perpendicular to deadlock lever first segment 71 and deadlock lever third section 73,
Wherein deadlock lever first segment 71 is installed in rotation in the axis hole 60 of lockset bracket, deadlock lever first segment 71 and lockset bracket 6
Between be equipped with reduction torsion spring 74, strike plate 5 offers for the notch 51 of 73 hanging buckle of deadlock lever third section, deadlock lever first segment 71
It is fixedly and coaxially connected the first centering block 81, earthing switch motive spindle 2 has been fixedly and coaxially connected the second centering block 82, the first centering block 81
And second be connected with shackle rod 83 between centering block 82, wherein one end of the first centering block 81 and shackle rod 83 is hinged, and transmission is drawn
The other end of bar 83 is close to the second centering block 82 and is equipped with strip hole 92, and the second centering block 82 is equipped with pin 91, pin in eccentric position
In the 91 insertion strip holes 92.
When earthing switch motive spindle 2 moves to "on" position by gate-dividing state, the second centering block 82 is transported with earthing switch
Dynamic 2 synchronous hunting of main shaft, the second centering block 82 drive the rotation of the first centering block 81, the first centering block 81 by pin 91 and shackle rod 83
It is rotated synchronously with deadlock lever 7, deadlock lever third section 73 leaves the notch 51 of strike plate, therefore cable chamber door 4 can be opened, that is, open
Lock, as shown in Fig. 8, Fig. 9, Figure 10, Figure 11, Figure 12；
When earthing switch motive spindle 2 moves to gate-dividing state by "on" position, the second centering block 82 is transported with earthing switch
Dynamic 2 synchronous backward of main shaft is swung, and the second centering block 82 drives 91 synchronous backward of pin to swing, and the pin 91 of the second centering block is drawn along transmission
The strip hole 92 of bar slides, therefore pin 91 loosens the pulling force to shackle rod 83, and shackle rod 83 loses to the first centering block 81
Pulling force, then reduction torsion spring 74 buckles into deadlock lever third section 73 in the notch 51 of strike plate the torsion of deadlock lever 7, at this time
Cable chamber door 4 cannot be opened, that is, be latched, as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6.
Above-mentioned strike plate 5 is installed on cabinet body rear wall 12 using bolt 93, and the nut of bolt 93 is located at 12 outside of cabinet body rear wall,
As shown in Fig. 6, Figure 12.In this way, can remove bolt 93 under failure and the state of emergency using specific purpose tool outdoors, unload
Strike plate 5 is opened cable chamber door by force and is overhauled.
Conversion of the above-mentioned earthing switch motive spindle 2 between "on" position and gate-dividing state, by earthing switch manipulator
Handle 3 is controlled by transmission mechanism 31, the second centering block 82, as shown in Figure 1 and Figure 2.
