The locking mechanism is widely used for lifesaving capsule doors.
Description
Technical field
A kind of capsule door of escape capsule for mining retaining mechanism of the utility model belongs to the capsule door of escape capsule for mining technical field.
Background technology
Linkage or turbine and worm mechanism are adopted in existing hatch door locking mostly, can not realize hatch door relative motion function, therefore can not realize well the sealing of hatch door.And retaining mechanism is a heat carrier, easily outside heat is imported in the cabin.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved provides a kind of simple and reasonable, a kind of capsule door of escape capsule for mining retaining mechanism of heat insulation, good sealing effect.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of capsule door of escape capsule for mining retaining mechanism, comprise: hatch door, holder, the first operation handwheel, hand wheel shaft and the second operation handwheel, described holder is embedded on the hatch door, hand wheel shaft is installed in the holder, one end of described hand wheel shaft is equipped with the first operation handwheel, the other end of described hand wheel shaft is equipped with the second operation handwheel, the middle part of described hand wheel shaft is equipped with the spider of check lock lever by screw thread, be provided with at least one long arc-shaped holes on the periphery of described check lock lever spider, evenly be provided with the alignment pin identical with described long arc-shaped holes quantity on the periphery of described holder, described each alignment pin all is inserted in the corresponding long arc-shaped holes of described check lock lever center disk, be provided with heat insulation between described check lock lever spider and the holder, be provided with spring between described heat insulation and the described check lock lever spider, be provided with sealing ring between described hand wheel shaft and the holder.
Be provided with bearing between described hand wheel shaft and the holder.
The utility model compared with prior art has following beneficial effect.
1, the utility model is simple and reasonable, drives check lock lever locking hatch door by screw thread, locks more reliably, and sealing effectiveness is better, effectively stops toxic gas to enter in the cabin.
2, the utility model guarantees that by between hand wheel shaft and holder bearing being set hand wheel shaft rotates flexibly; At hand wheel shaft heat insulation is set, effectively blocking-up heat transmission out of my cabin.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Among the figure: 1 is that hatch door 1,2 is holder, and 3 is the first operation handwheel, and 4 is hand wheel shaft, and 5 is the second operation handwheel, and 6 is check lock lever, and 7 is alignment pin, and 8 is heat insulation, and 9 is spring, and 10 is sealing ring, and 11 is bearing.
The specific embodiment
Such as Fig. 1, shown in Figure 2, a kind of capsule door of escape capsule for mining retaining mechanism, comprise: hatch door 1, holder 2, the first operation handwheel 3, hand wheel shaft 4 and the second operation handwheel 5, described holder 2 is embedded on the hatch door 1, hand wheel shaft 4 is installed in the holder 2, one end of described hand wheel shaft 4 is equipped with the first operation handwheel 3, the other end of described hand wheel shaft 4 is equipped with the second operation handwheel 5, it is characterized in that: the middle part of described hand wheel shaft 4 is equipped with the spider of check lock lever 6 by screw thread, be provided with at least one long arc-shaped holes on the periphery of described check lock lever 6 spiders, evenly be provided with the alignment pin 7 identical with described long arc-shaped holes quantity on the periphery of described holder 2, described each alignment pin 7 all is inserted in the corresponding long arc-shaped holes of described check lock lever 6 center disk, be provided with heat insulation 8 between described check lock lever 6 spiders and the holder 2, be provided with spring 9 between described heat insulation 8 and described check lock lever 6 spiders, be provided with sealing ring 10 between described hand wheel shaft 4 and the holder 2.
Be provided with bearing 11 between described hand wheel shaft 4 and the holder 2.
The quantity of alignment pin and long arc-shaped holes is two in the utility model.
The course of work of the present utility model is: when needs are opened hatch door 1, rotation the first operation handwheel 3, the upper screw thread of hand wheel shaft 4 makes check lock lever 6 moving axially along alignment pin 7, when check lock lever 6 moves to the screw thread terminated line, owing to being provided with spring 9 between check lock lever 6 spiders and the holder 2, spring 9 compresses check lock lever 6, and check lock lever 6 can not be rotated freely; When continuing rotation the first operation handwheel 3, under the effect of spring 9 and hand wheel shaft 4 screw threads, long arc-shaped holes on check lock lever 6 spiders is rotated to an angle along the direction of rotation of alignment pin 7 to the first operation handwheel 3, check lock lever 6 and doorframe are broken away from, open hatch door, when needs locking hatch door 1, identical with above-mentioned principle.
The method of operation the second operation handwheel 5 is identical with operation the first operation handwheel 3.
The above has done detailed description to embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skills possess, can also under the prerequisite that does not break away from the utility model aim, make various variations.
