Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description.
The present invention provides a kind of switch cabinet shutter blocking mechanisms, and as depicted in figs. 1 and 2, the blocking mechanism is in breaker
After handcart pulls out, it can prevent worker's maloperation from opening valve with automatic blocking valve, avoid the generation of safety accident.
Switch cabinet shutter blocking mechanism as depicted in figs. 1 and 2, including the bracket being fixed on the side cabinet of switchgear
1, latch plate 2 and connecting lever 3 are hingedly installed on bracket 1, the hinge joint 1 of latch plate 2 is located at the upper of the hinge joint 25 of connecting lever 3
Side, and latch plate 2 is between connecting lever 3 and bracket 1；3 one end of connecting lever is equipped with only lock pillar 6, offered in latch plate 2 can with only
The notch 1 that lock pillar 6 cooperates；3 other end of connecting lever passes through the upper valve 9 and lower valve 10 of 8 connecting switch cabinet of drive link, connecting lever
The compression bar 11 for keeping balance is connected on 3；The spacer pin 12 for limiting the rotation of latch plate 2, connecting lever are provided on bracket 1
It is located on 3 and only opens up notch 2 13 between lock pillar 6 and compression bar 11.
Bearing spindle 14 of the hinge joint 25 including connecting lever 3 and bracket 1, the bearing 15 on bearing spindle 14, with
And circlip 16 and bearing positioning plate 17 outside bearing 15.Circlip 16 and bearing positioning plate 17 can prevent bearing 15 from falling off.
Using the frictional force for reducing connecting lever 3 and shaft after bearing, rotates connecting lever 3 more flexible, extend a whole set of valve mechanism
Service life, while also ensuring the cooperation precision of connecting lever 3 and bracket 1.
The other side for being located at only lock pillar 6 on connecting lever 3 is provided with screw 18, and idler wheel 19, breaker hand are set with outside screw 18
After vehicle 20 promotes, idler wheel 19 rolls below the long angle steel 21 of circuit breaker cart.
Unlocking process as shown in Figure 5：
When circuit breaker cart 20 runs to operating position by testing position, frizzen on circuit breaker cart 20 22 first with close
2 front end of jam plate starts to contact (Fig. 5:Circuit breaker cart 20 is located at reference line location A), circuit breaker cart 20 is to far from reference line A
Direction movement, only lock pillar 6 is detached from 2 notch one of latch plate and realizes unlock (Fig. 5：Circuit breaker cart 20 is located at B location), frizzen 22
Temporarily into the notch 2 13 on connecting lever 3, circuit breaker cart 20 continues to move to far from the direction reference line A, and frizzen 22 is detached from
Notch two, into operating position；Latch plate 2 is fallen by self gravitation effect, rotation, is stopped latch plate 2 to fall by spacer pin 12
It no longer falls (Fig. 5 to certain angle：Circuit breaker cart 20 is located at location of C), upper and lower valve is opened, as shown in Figure 3.At this point, disconnected
Road device handcart 20 will continue to travel forward, and frizzen 22 will continue to the end that compression bar 11 is moved to along compression bar 11, realize circuit
Closure.
Latching process as shown in FIG. 6：
When circuit breaker cart 20 runs to testing position by operating position, the frizzen on circuit breaker cart 20 temporarily enters
Notch 2 13 on connecting lever 3, then first with latch plate 2 after end in contact (Fig. 6:Circuit breaker cart 20 is located at the position D), latch plate
2 lift, and circuit breaker cart 20 is moved to close to the direction reference line A, and latch plate 2 is lifted up (Fig. 6：Circuit breaker cart 20 is located at
The position E), circuit breaker cart 20 continues to move to close to the direction reference line A, and circuit breaker cart 20 enters testing position, latch plate 2
By self gravitation effect, rotation is fallen, and 2 notch one of latch plate cooperates with only lock pillar 6, realizes locking (Fig. 6：Circuit breaker cart 20
Return to reference line location A), upper and lower valve is closed, as shown in Figure 4.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
