Embodiment
As depicted in figs. 1 and 2, perforate on explosion-proof body 5, is arranged in this hole by the first axle bed 7, and the first axle bed 7 is provided with through hole, the anxious bar 1 that stops raming is penetrated into explosion-proof body 5 from the through hole of the first axle bed 7 inner.Back-moving spring 6 is located at the first axle bed 7 and anxious is stopped raming between bar 1, and slip cap 8 is arranged in the part that the anxious bar 1 that stops raming stretches in explosion-proof body 5 by pin 9, rams 21 to be connected with the urgency end that bar 1 stretches in explosion-proof body 5 of stopping raming.
Slip cap 8 is provided with inclined-plane, the slopes which match in this inclined-plane and gangbar 2.
Second axle bed 11 is arranged on explosion-proof body 5, near the position of explosion-proof shell bodily movement of practising Wushu orchid 18, is positioned at the right side of the first axle bed 7 simultaneously.Second axle bed 11 is provided with through hole, and the through hole of operating axis 14 from the inside of explosion-proof body 5 along the second axle bed 11 passes.One end of yoke plate 10 is arranged on the inner (being located at one end of the inside of explosion-proof body 5) of operating axis 14 by securing member 4 (such as screw), operator sleeve 12 is connected to the outer end (being located at one end of the outside of explosion-proof body 5) of operating axis 14 by securing member 13 (such as screw or bolt), and operator sleeve 12 is provided with breach 26.The other end of operating axis 14 is provided with groove 25.Cushion cover 15 is provided with between yoke plate 10 and the second axle bed 11.The other end of yoke plate 10 is connected with gangbar 2 by screw.
Locking bent plate 17 is arranged on the side of explosion-proof body 5, and locking bent plate 17 is connected with axle sleeve.Explosion-proof shell bodily movement of practising Wushu blue 18 is connected with explosion-proof body 5, and explosion-proof door closure flange 19 is located at explosion preventing gate and is covered.Latch shaft 16 is arranged in the axle sleeve on locking bent plate 17, and Breech block 20 is arranged on explosion-proof door closure flange 19, and Breech block 20 is provided with hole.
By rotating latch shaft 16, one end can the rotation of control operation taper knob 12, and the other end, through flame-proof switch body flange 18, controls the Breech block 20 be contained on explosion-proof door closure flange 19.When latch shaft 16 moves to left, can in the breach 26 of update taper knob 12, such operator sleeve 12 just can not rotate, and electric switch now can not power transmission, and explosion-proof door closure can be opened.When in the hole that latch shaft 16 is shifted to the right to Breech block 20, explosion-proof door closure can not be opened, and operator sleeve 12 is rotatable thus make electric switch power transmission.
As shown in Figure 3 and Figure 4, one end of gangbar 2 is provided with the connecting hole 22 be connected with yoke plate 10, and the other end of gangbar 2 is provided with sliding tray 23 and sliding bevel 24, and slip cap 8 is connected with sliding tray 23, the contact of incline plane of sliding bevel 24 and slip cap 8.
The course of work is:
By rotating operation axle 14, the power transmission change over switch divide-shut brake axle that stops be arranged on electric control unit be connected with the groove 25 on it is rotated, and then control the work of flame-proof switch.Meanwhile, yoke plate 10 drives gangbar 2, and gangbar 2 is driven by its inclined-plane suddenly stops bar 1 stretching motion of raming, the major loop circuit breaker power-off in energy direct control flame-proof switch, or allows it to close a floodgate; When carrying out flame-proof switch electrical overhaul, rotating operation axle 14, makes groove 25 steering horizontal on it, by the breach 26 of latch shaft 16 update taper knob 12, makes it not carry out power transmission operation.Meanwhile, the bar 1 that suddenly stops to ram stretches into, and rams 21 to stop action bars press-in, circuit breaker disjunction, major loop power-off by anxious for circuit breaker.Now, door closure just can be opened, and carries out maintenance work.By back-moving spring 6, will ram 21 departs from electric switch, avoid next time electrical installation time, can not normally close a floodgate.Said apparatus achieves an Electricity Federation lock reliably.
The above only to preferred embodiment of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.Every in the claim limited range of utility model, any amendment made, equivalent replacement, improvement etc., all should within protection range of the present utility model.
