Embodiment
Shown in Fig. 1, Fig. 2, Fig. 3, Fig. 9, Figure 12, operating grip and the back door mechanical lock of this fixed switching cabinet comprise cabinet 1, before cabinet, 10 are provided with operating grip 11 rotationally, and operating grip 11 is formed with " maintenance " position, " work " position, " disjunction locking " position along clockwise direction successively; Be provided with fixing rear wall 21, rear door frame 23 after cabinet, rear door frame 23 can be put down to turn up the soil and is movably installed with back door 22.Shown in Fig. 1, Fig. 2, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Figure 15, back door 22 is provided with strike plate 24, rear door frame 23 offers the jack 25 longitudinally penetrated for back door lock tongue piece 24, described cabinet rear wall 21 is installed with lockset support 3, round bar shaped bolt 4 can be installed transverse shifting in lockset support 3, strike plate 24 offers the lockhole 40 that bolt can be supplied laterally inserted, and bolt 4 is fixedly connected with driver blade 41, and driver blade 41 offers vertical elongated hole 42; Longitudinal locking power transmission shaft 5 is provided with between cabinet front portion and cabinet rear portion, locking power transmission shaft 5 is driven and rotating in same direction by operating grip 11, the rear end of locking power transmission shaft 5 is fixedly connected with centering block 43, centering block 43 swings under the driving of locking power transmission shaft 5, centering block 43 is fixed with trundle 44, trundle 44 is inserted in the vertical elongated hole 42 of driver blade 41; Shown in Figure 12, Figure 13, when operating grip 11 pushes " maintenance " position, operating grip 11 drives bolt 4 to move to the left end of stroke by locking power transmission shaft 5, centering block 43, trundle 44, driver blade 41, and the right-hand member of bolt 4 departs from the lockhole 40 of strike plate; Shown in Fig. 9, Figure 10, Figure 11, when operating grip 11 pushes " work " position, operating grip 11 drives the right-hand member of bolt 4 to insert the lockhole 40 of strike plate by locking power transmission shaft 5, centering block 43, trundle 44, driver blade 41; Shown in Fig. 3, Fig. 4, Fig. 6, when operating grip 11 pushes " disjunction locking " position, operating grip 11 also drives the right-hand member of bolt 4 to insert the lockhole 40 of strike plate by locking power transmission shaft 5, centering block 43, driver blade 41.
Shown in Fig. 5, Fig. 8, Figure 15, Fig. 6, bolt 4 is also fixed and joins together limited location pin 45; Lockset support 3 is provided with can the locking piece 6 of horizontal hunting, the vertical rotating shaft 60 of locking piece 6 is fixedly mounted on lockset support 3, when the end (right-hand member namely in Figure 14) of locking piece 6 is to after the rotation of the direction of rear door frame 23, the terminal position of locking piece 6 aims at the jack 25 of rear door frame; The rear of locking piece 6 offers along middle the breach 61 coordinated with bolt spacer pin 45.
Shown in Figure 15, when bolt 4 is in the left end of its stroke, the breach 61 of locking piece is aimed in the lateral attitude of bolt spacer pin 45; Shown in Fig. 8, Figure 15, Fig. 6, lockset support 3 is also provided with the back-moving spring 8 locking piece 6 being applied to horizontal pull, the direction of pull of back-moving spring 8 pairs of locking piece 6 is that the end of locking piece 6 is rotated backward.
Above-described embodiment use principle is as follows:
When operating grip 11 turns to " disjunction locking " position along clockwise direction (as shown in Figure 3), operating grip 11 drives centering block 43 to swing to the right by locking power transmission shaft 5, driver blade 41 is driven to drive bolt 4 to move to the right-hand member of stroke, bolt 4 inserts the lockhole 40 of strike plate 24 to the right, as shown in Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, the lateral attitude of bolt spacer pin 45 and the breach about 61 of locking piece stagger; Now, strike plate 24 can not retreat, and means that back door 22 cannot be opened, and the pulling force that simultaneously strike plate 24 overcomes back-moving spring 8 withstands forward the end of locking piece 6, and bolt spacer pin 45 does not enter the breach 61 of locking piece, and bolt can free transverse shifting;
When operating grip 11 turns to " work " position (as shown in Figure 9) in the counterclockwise direction, drive bolt 4 slightly to moving left, bolt 4 keeps the lockhole 40 inserting strike plate 24, and the lateral attitude of bolt spacer pin 45 and the breach 61 of locking piece still left and right stagger; Back door 22 still cannot be opened, and as shown in Figure 10, Figure 11, state class shown in situation and Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 seemingly;
When operating grip 11 turns to " maintenance " position (as shown in figure 12) in the counterclockwise direction, operating grip 11 drives centering block 43 to swing left by locking power transmission shaft 5, driving driver blade 41, bolt 4 move to the left end of stroke, make the lateral attitude of bolt 4 spacer pin 45 aim at the lateral attitude of the breach 61 of locking piece, the right-hand member of bolt 4 is deviate from from the lockhole 40 of strike plate 24 simultaneously; After bolt 4 is deviate from from the lockhole 40 of strike plate 24, strike plate 24 can retreat from the jack 25 of rear door frame 23, and namely back door 22 can be opened backward; After back door 22 is opened backward, strike plate 24 no longer withstands the end of locking piece 6, so the end of locking piece 6, under the pulling force effect of back-moving spring 8, rotates backward, the breach 61 of locking piece 6 is driven to rotate backward, so the spacer pin 45 on bolt 4 enters breach 61, make bolt 4 no longer can transverse movement, as shown in Figure 12, Figure 13, Figure 14, therefore operating grip 11 can not rotate, namely operating grip 11 can not push " work " position, " disjunction locking " position, guarantees maintainer's safety; Maintenance is only had to complete, after back door closes again, strike plate 24 withstands the end of locking piece 6 again, and locking piece breach 61 is rotated forward, and the spacer pin 45 on bolt 4 departs from breach 61, bolt 4 just can transverse shifting, and operating grip 11 just can push " work " position, " disjunction locking " position.
