Summary of the invention
The utility model provides the mechanical interlocks on the double door Flameproof box of a kind of down-hole, solves existing screw interlocking device and takes up room large and do not allow easy-operating technical problem.
The utility model solves above technical problem by the following technical programs:
Mechanical interlocks on the double door Flameproof box of a kind of down-hole, comprise Flameproof box casing, Flameproof box left-hand door body and the right door body of Flameproof box, Flameproof box casing between Flameproof box left-hand door body and the right door body of Flameproof box is provided with to interlock and isolates handle, the head of interlocking isolation handle is provided with zigzag and rotates biconvex wheel disc, rotate on biconvex wheel disc at zigzag and be provided with left groove and right groove, the Flameproof box casing that Flameproof box left-hand door body and zigzag rotate between biconvex wheel disc is provided with left pin rod bearing, left step through-hole is movably set with in left pin rod bearing, in left step through-hole, activity cross-under has left pin rod, the left pin rod step of left pin rod is socketed with left stage clip, the right flank of Flameproof box left-hand door body is fixedly installed Left-wing Federation's jam plate, the right-hand member movable top of left pin rod is connected in left groove, the left end of left pin rod is arranged on the below of Left-wing Federation's jam plate, Flameproof box casing between Flameproof box right Men Tiyu zigzag rotation biconvex wheel disc is provided with right pin rod bearing, right step through-hole is movably set with in right pin rod bearing, in right step through-hole, activity cross-under has right pin rod, the right pin rod step of right pin rod is socketed with right stage clip, the left surface of Flameproof box right door body is fixedly installed right interlock plate, the left end movable top of right pin rod is connected in right groove, and the right-hand member of right pin rod is arranged on the below of right interlock plate.
Left pin rod bearing and right pin rod bearing are for symmetry axis is symmetrical set with the vertical direction up and down being rotated the central point of biconvex wheel disc by the zigzag of the head of isolating handle of interlocking.
The utility model adopts spring reset principle, does not need manual operation, without the need to reserving manual operation space, avoiding the not easy-operating drawback in little space, taking up room little, efficiently solves the electromechanical interlock problem that little Space Double is opened the door.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that operation of the present utility model uses schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
Mechanical interlocks on the double door Flameproof box of a kind of down-hole, comprise Flameproof box casing 3, Flameproof box left-hand door body 1 and the right door body 9 of Flameproof box, Flameproof box casing 3 between Flameproof box left-hand door body 1 and the right door body 9 of Flameproof box is provided with to interlock and isolates handle 6, the head of interlocking isolation handle 6 is provided with zigzag and rotates biconvex wheel disc, rotate on biconvex wheel disc at zigzag and be provided with left groove 17 and right groove 18, the Flameproof box casing 3 that Flameproof box left-hand door body 1 and zigzag rotate between biconvex wheel disc is provided with left pin rod bearing 4, left step through-hole 5 is movably set with in left pin rod bearing 4, in left step through-hole 5, activity cross-under has left pin rod 10, the left pin rod step 12 of left pin rod 10 is socketed with left stage clip 11, the right flank of Flameproof box left-hand door body 1 is fixedly installed Left-wing Federation's jam plate 2, the right-hand member movable top of left pin rod 10 is connected in left groove 17, the left end of left pin rod 10 is arranged on the below of Left-wing Federation's jam plate 2, the Flameproof box casing 3 that Flameproof box right door body 9 and zigzag rotate between biconvex wheel disc is provided with right pin rod bearing 7, right step through-hole 15 is movably set with in right pin rod bearing 7, in right step through-hole 15, activity cross-under has right pin rod 16, the right pin rod step 13 of right pin rod 16 is socketed with right stage clip 14, the left surface of Flameproof box right door body 9 is fixedly installed right interlock plate 8, the left end movable top of right pin rod 16 is connected in right groove 18, and the right-hand member of right pin rod 16 is arranged on the below of right interlock plate 8.
Left pin rod bearing 4 is for symmetry axis is symmetrical set with the vertical direction up and down being rotated the central point of biconvex wheel disc by the zigzag of the head of isolating handle 6 of interlocking with right pin rod bearing 7.When isolation handle 6 of interlocking is in A position, two pin rods, under the effect of stage clip, return in respective groove, and Left-wing Federation's jam plate 2 and right interlock plate 8 can fall, and door can be opened, and at this moment the isolating switch of isolating in casing is in off-state.When isolation handle 6 of interlocking from A position to B position outstanding turn time, pin rod is under zigzag rotates the promotion of the projection on biconvex wheel disc, compress two stage clips, two pin rods all reach immediately below interlock plate, Left-wing Federation's jam plate 2 and right interlock plate 8 are prevented from falling, door cannot be opened, and at this moment the isolating switch of isolating in casing is in opening state.
