The lifesaving hatch door, comprise hatch door, handwheel and screw mandrel, also comprise and press box in clamping frame, combination nut, hold down gag and the hold down gag, described handwheel is fixed on described screw mandrel two ends, described hold down gag is nested with on described screw mandrel, and described clamping frame is fixedlyed connected with described combination nut, and described combination nut is connected with described wire rod thread, described screw mandrel is rotationally connected by bearing and described hatch door, presses box to fixedly connected with described hatch door in the described hold down gag.
Further, described hold down gag comprises spring base and stage clip, and described spring base and described stage clip are nested with on described screw mandrel, and described stage clip one end is pressed in the described spring base, and the described stage clip other end is pressed on the described combination nut.
Further, described spring base is with interior protective cover outward, and described interior protective cover is fixed on the described combination nut.
Further, have the arc locating hole on the described combination nut, pressing on the box in the described hold down gag fixedly has backstay.
Further, described clamping frame comprises the cylindrical cavity of criss-cross depression bar and fixing described combination nut.
Further, described screw mandrel is equipped with rotating seal outward, and described rotating seal is equipped with the locking device outer end cap outward, and described locking device outer end cap is equipped with outer protective cover outward, and described locking device outer end cap and described outer protective cover all are fixed on the hatch door.
Further, described screw mandrel is the coarse pitch trapezoidal screw.
The utility model beneficial effect is: the setting of handwheel and screw mandrel, can realize the opening and closing of hatch door inside and outside the survival capsule, and easy and simple to handle; The coarse pitch trapezoidal screw arrange can be in the shortest time opening and closing hatch door and self-locking property good; Compression plate and compress inner box clamping frame is positioned, and help to strengthen tightness.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model structural representation;
Fig. 2 is the schematic diagram of combination nut among Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
See figures.1.and.2, the lifesaving hatch door, comprise hatch door 1, handwheel 2 and screw mandrel 3, also comprise and press box 7 in clamping frame 4, combination nut 5, hold down gag 6 and the hold down gag, described handwheel 2 is fixed on described screw mandrel 3 two ends, described hold down gag 6 is nested with on described screw mandrel 3, described clamping frame 4 is fixedlyed connected with described combination nut 5, described combination nut 5 is threaded with described screw mandrel 3, described screw mandrel 3 is rotationally connected by bearing and described hatch door 1, presses box 7 to fixedly connected with described hatch door 1 in the described hold down gag.
Further, described hold down gag 6 comprises spring base 61 and stage clip 62, and described spring base 61 and described stage clip 62 are nested with on described screw mandrel 3, and described stage clip 62 1 ends are pressed in the described spring base 61, and the described stage clip other end is pressed on the described combination nut 5.Spring base and stage clip are used for making combination nut and screw mandrel that excellent contact be arranged, and improve combination nut along the flexible stationarity of screw mandrel.
Further, protective cover 9 in described spring base 61 outer being with, described interior protective cover 9 is fixed on the described combination nut 5.Interior protective cover mainly plays protection spring base and stage clip.
Further, have arc locating hole 51 on the described combination nut 5, pressing on the box 7 in the described hold down gag fixedly has backstay 71.The arc locating hole cooperates with backstay, and just clamping frame just stops operating to certain position, only in the screw mandrel axially-movable.
Further, described clamping frame 4 comprises the cylindrical cavity (not shown) of criss-cross depression bar (not shown) and fixing described combination nut.Depression bar is used for compressing inwall, plays the wiper seal effect.
