Detailed description of the invention

Embodiment, see shown in Fig. 1 to Fig. 3: a kind of without electric-opening skylight, comprise the framework 2 of inclination, be arranged on the guide rail 5 in framework 2, window lid 1, be fixed on window lid 1 and slide on the slide mechanism 4 on guide rail 5, framework 2 comprises upper end 21 and lower end 22, one end high in framework 2 is upper end 21, low one end is lower end 22, in upper end 21, boosting mechanism 3 is installed, boosting mechanism 3 can push against at the edge of window lid 1 and promote window lid 1 and move, position limit device 6 and lower caging device 7 is separately installed with at the two ends of guide rail 5, slide mechanism 4 can be stopped at position limit device 6 or lower caging device 7 respectively, lower end 22 is also provided with vertical type snubber 8, vertical type snubber 8 to be resisted against on window lid 1 and buffering stop window lid 1, oil storage type snubber in vertical type snubber 8 preferably adopts, by the effect of gravity, window lid 1 can slide toward lower end 22 along guide rail 5 from upper end 21.Interior oil storage type snubber primary structure is the compositions such as body, axle center, bearing, interior pipe, piston, hydraulic axis, spring, when the hydraulic oil that axle center will be managed in drive piston press by external impacts, to be discharged one by one by the outage of interior pipe after hydraulic oil pressurized, also be back to interior pipe by the spill port of interior pipe by the hydraulic oil of interior pipe discharge simultaneously; When external force disappears, the action that piston rebounds initial point wait next time by spring.

Boosting mechanism 3 comprises boosting cylinder 31, control valve 33 and gasholder 32, boosting cylinder 31 to be connected in framework 2 and the axis being parallel of the output shaft of boosting cylinder 31 in guide rail 5, control valve 33 and gasholder 32 are positioned at framework 2 and are communicated to boosting cylinder 31 by tracheae 34, the output shaft of boosting cylinder 31 can be resisted against the edge of window lid 1, boosting cylinder 31 is preferably mounted in guide rail 5 end, and boosting cylinder 31 can send a thrust promotion window lid 1 to the edge of window lid 1 and move along guide rail 5.

Slide mechanism 4 is symmetrically distributed on window lid 1, slide mechanism 4 comprises installing rack 41, be arranged on the roller 42 on installing rack 41 and the punching 43 being fixed on installing rack 41, punching 43 is provided with buffer stopper 44, installing rack 41 is connected in window lid 1, roller 42 is limited on guide rail 5 and also can slides along guide rail 5, the punching 43 at slide mechanism 4 two ends is respectively towards the outside at window lid 1 two ends, buffer stopper 44 is made up of elastomeric material, position limit device 6 and lower caging device 7 all include the shock surface 61 perpendicular to guide rail 5, the shock surface 61 of position limit device 6 and the shock surface 61 of lower caging device 7 are just to setting, when window lid 1 impacts position limit device 6 or lower caging device 7, buffer stopper 44 on the slide mechanism 4 of window lid 1 one end can impact and be stopped on shock surface 61.

Operating principle/process:

Open the course of action of window lid 1: window lid 1 is parked in and window lid 1 position limit device 6 contact position before manual unlocking operation, by operation control valve 33 while manual operation unlocks, gasholder 32 compressed air accesses boosting cylinder 31 by tracheae 34, the piston rod of boosting cylinder 31 stretches out and promotes window lid 1, slide mechanism 4 drives window lid 1 slide along guide rail 5 and move down, and this system realizes the unlatching of window lid 1 or discharges more reliably fast.

The course of action of window lid 1 stop: when window lid 1 moves down along guide rail 5, the axle center of vertical type snubber 8 is first touched at the edge of window lid 1, the axle center of vertical type snubber 8 is hit and advances in snubber chamber, the speed that the damping force that vertical type snubber 8 produces makes window lid 1 run declines fast, impact energy is all absorbed by vertical type snubber 8 vertical type, kinetic transformation is that heat energy is outwardly distributed by vertical type snubber 8, when buffer stopper 44 touches the shock surface 61 of lower caging device 7, translational speed is down to zero, and lower caging device 7 plays security insurance effect.

These are only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize manual of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
