Description
Technical field
The utility model relates to the mounting structure of ceiling access hole, the ceiling access cover device of particularly a kind of large scale band location lock.
Background technology
Decorative house ceiling in the daily life; For the convenience of overhauling in the future; Usually all leave at least one maintenance window, the access cover that is contained in the maintenance window comprises an access cover that is fixed on the manhole framework on the ceiling keel and flexibly connects with the manhole framework.Access cover can open or close in activity, and the maintenance people can stretch into ceiling with head or hand and carries out service work when opening, and makes when closing indoorly to keep isolating with ceiling top.
Do not have special blocking device between existing manhole framework and the access cover, especially large-sized access cover causes the play of access cover easily, cooperates not closely, opens and closes inconvenient.
Summary of the invention
Exist cooperation not tight to the large-sized access cover device of prior art; Open and close inconvenient defective; The utility model provides no-float between a kind of manhole framework and the access cover, and good airproof performance is opened the ceiling access cover device of closing a kind of easily large scale band location lock.
For realizing the foregoing invention purpose, the utility model adopts following technical scheme:
The ceiling access cover device of a kind of large scale band location lock; The access cover that comprises the manhole framework that is fixed in ceiling, flexibly connects with the manhole framework; Described access cover comprises the access cover outside framework; Access panel is fixed in the access cover outside framework, and the location lock is set on the described manhole framework first side, and described location lock comprises lock body, passes through hinge and the hinged tapered end of lock body; Suit back-moving spring on the hinge, described access cover outside framework first side upwards promote tapered end and move to lock body and lock.
As preferably, described tapered end cross section is fan-shaped, an end fixed limit pulley of fan-shaped arc, and the other end of fan-shaped arc has spacing preiection, is provided with the spacing draw-in groove that matches with spacing preiection in the described lock body.Spacing pulley sticks into the stopper slot on the pushing block, and pushing block promotes tapered end and moves to lock body, and spacing preiection gets into spacing draw-in groove, tapered end and lock body locking; When needing release, promote pushing block, because the effect of back-moving spring, spacing preiection breaks away from spacing draw-in groove, the release success.
As preferably, described location lock is two, is arranged on the two ends of manhole framework first side.Two pairs position locking better.Manhole framework two ends are provided with the location lock can make the large scale access cover more firm.
As preferably, the position corresponding with tapered end is provided with two locking banking stops on the described access cover outside framework first side.Conveniently lock.
As preferably, the two ends of described manhole framework second side are provided with two banking stops.Access cover is carried out spacing, make access cover the chucking in the second side can upwards not move handled easily.
As preferably, on the right angle of described access cover outside framework second side L shaped spacer is set.Guarantee that the access cover second side can not fall down, and increases the compactness that cooperates.
As preferably, on described manhole framework and the access cover outside framework fixing hole is set, connect the draw ring that can throw off between two fixing holes.When draw ring is opened access cover, can not fall down suddenly.
As preferably, the junction of described manhole framework and access cover is provided with weather strip.The two connection is tightr, good airproof performance.
No-float between the ceiling access cover turnaround of unit hole framework of a kind of large scale band location lock of the utility model and the access cover, good airproof performance is opened and closed conveniently, and is safe.

Specific embodiment
Below in conjunction with the accompanying drawing 1-6 and the specific embodiment the utility model is described in further detail:
The ceiling access cover device of a kind of large scale band location lock; Shown in Fig. 1-6, comprise the manhole framework 1 that is fixed in ceiling, with the access cover 2 that manhole framework 1 flexibly connects, described access cover 2 comprises access cover outside framework 21; Access panel 22 is fixed in the access cover outside framework 21; Location lock 3 is set on described manhole framework 1 first side, and described location lock 3 comprises lock body 31, through the hinged tapered end 32 of hinge 33 and lock body 31, suit back-moving spring 8 on the hinge 33; Described tapered end 32 cross sections are fan-shaped; One end fixed limit pulley 5 of fan-shaped arc, the other end of fan-shaped arc has spacing preiection 12, is provided with the spacing draw-in groove 7 that matches with spacing preiection 12 in the described lock body 31.Described location lock 3 is two, is arranged on the two ends of manhole framework 1 first side, is provided with two locking banking stops 4 with tapered end 32 corresponding positions on described access cover outside framework 21 first sides.The two ends of described manhole framework 1 second side are provided with two banking stops 10, on the right angle of described access cover outside framework 21 second sides L shaped spacer 11 are set.Fixing hole 9,13, two fixing holes 9 are set on described manhole framework 1 and the access cover outside framework 21, connect the draw ring 14 that can throw off between 13, manhole framework 1 is provided with weather strip 15 with the junction of access cover 2.
During use, with access cover 2 from the below toward buckling into manhole framework 1, the position is no more than banking stop 10; Spacer 11 extend into the upper surface of manhole framework 1 second side; Access cover 2 is upwards pressed, and the spacing pulley 5 that access cover outside framework 21 first sides promote location lock 3 moves up, and spacing preiection 12 slowly sticks into spacing draw-in groove 7; At this moment, i.e. locking between access cover 2 and the manhole framework 1.In the time of need opening access cover 2, access cover 2 is upwards pushed up, because the effect of back-moving spring 8, spacing preiection 12 is separated from spacing draw-in groove 7, and location lock 3 is unlocked, and can take off access cover 2 this moment.
