The specific embodiment
(embodiment 1)
See Fig. 1, the present invention includes a body 1 and a door body jack 2, door body 1 be the middle part hinged, open the back and become tabular, draw the bellow framed door body that the back forms inside and outside layer 12,11 in, the bottom of door volume surrounding 11 is hinged on the car body 8; Place, door volume surrounding 11 medial surface both sides of the edge respectively is provided with connecting rod rest 4, the narrow distance between two connecting rod rests 4 of door body internal layer 12 width, between connecting rod rest 4 and the door volume surrounding 11 and be hinged between the connecting rod 5 of connecting rod rest 4, the two ends of connecting rod rest 4 upper booms are connected by drag-line inside and outside layer 12,11 with the door body respectively; Described door body jack 2 is drag-line jacks, and the outer end of its drag-line 21 becomes two stocks not to be connected with the inside and outside layer 12,11 of door body; The internal layer 12 of door body 1 is provided with the door lock 3 that 12 whiles of door body internal layer and door volume surrounding 11 and car body 8 are locked mutually; Respectively be connected with between door volume surrounding 11 medial surface both sides of the edge and the car body and strengthen drag-line 6.
See Fig. 2, described drag-line jack tool comprises the two stands 29 that is fixed on the car body 8 from the deceleration function, is provided with a transmission shaft 22 between the two stands 29, and the two ends of transmission shaft 22 respectively are provided with the guy anchor 23 that twines drag-line 21; Also be connected with the handle head motion of forming by worm couple 24 and gear pair 25 on the transmission shaft 22; Its deceleration is to take on transmission shaft 22 thread segment to be set, and thread segment is provided with and thread segment ingear nut 26, axially is connected with support member 27 on the transmission shaft 22, is connected a gas spring 28 between nut 26 and support member 27.
See Fig. 3, described door lock 3 comprises the base plate 31 that is fixed on the body internal layer, base plate 31 two ends are equipped with main tapered end 32 and secondary tapered end 33, the dead bolt of main tapered end 32 cooperates with cooresponding lockhole 71 on the car body 8, the dead bolt of secondary tapered end 33 cooperates with cooresponding lockhole 72 on the door volume surrounding, the dead bolt of each major and minor tapered end 32,33 is driven by connecting rod 35 respectively by revolving part 34 and moves, be fixedly connected with operating handle 36 on the revolving part 34 and bump pearl locations 37, on base plate 31 relevant positions, be provided with and bump the locating piece 38 that pearl locations 37 matches.
During use, pull the operating handle 36 of door lock 3 earlier, operating handle 36 moves by the dead bolt that revolving part 34 and connecting rod 35 drive each major and minor tapered end 32,33, remove the locking of opposite house body 1, moving door body 1 is tried hard to recommend in personnel selection again, the effect of door body 1 self gravitation outwards upset is opened, and door body internal layer 12 also can be opened because of the outside upset of inertia; When door body 1 was opened, connecting rod 5 was subjected to the traction of front end drag-line, and connecting rod rest 4 is stood on the volume surrounding 11, formed handrail; Drag-line 21 drives transmission shaft 22 rotations by guy anchor 23 simultaneously, nut 26 on transmission shaft 22 thread segments is axially moved and oppress pneumatic spring 28, when door body 1 is opened to the desired location, pneumatic spring 28 begins to limit nut 26 and axially moves, thereby the rotation of restriction transmission shaft 22, finally under the combined action of strengthening drag-line 6 body 1 is stopped, door body 1 forms an easy gradient, and is current for the crowd.When needs draw emergency exits in, can drive transmission shaft 22 by the handle head motion that worm couple 24 and gear pair 25 are formed rotates, the guy anchor that is fixed on transmission shaft 22 two ends twines drag-line 21, draw the door body in appropriate location, by manpower door body 1 is pulled back again, be locked on the locomotive and get final product.
