Abstract

The utility model discloses an exposed frame for a repair manhole of the ceiling, which comprises an outer frame and an inner frame embedded in the outer frame; the inner frame is articulated on the outer frame through a pivot, and a lock catch pin is perpendicularly arranged at the outer side of the inner frame being far from the hinged end, the lock catch pin is arranged in a lock catch pin hole arranged at the outer side of the inner frame, one end of the lock catch pin extends from the bottom edge of the inner frame and is provided with a screwing mechanism, and the other end thereof is bent into a lock catch end; a slotted hole is arranged at a position corresponding to the outer frame, the lock catch end can screw in and screw out in the slotted hole. With the lock catch pin arranged on the inner frame, the lock catch pin can be screwed into the slotted hole for locking purpose and screwed out from the slotted hole for opening purpose, so the open and the close of the repair manhole is convenient, furthermore, the structure is simple and the manufacture is easy, which can considerably reduce the manufacturing cost.

Description

The bright posture framework of ceiling service ports

Technical field

The utility model relates to a kind of ceiling service ports mounting structure, relates to the bright posture framework of a kind of ceiling service ports particularly.

Background technology

Existing ceiling service ports framework generally includes inner frame and outside framework, and outside framework is fixed on the ceiling keel, and inner frame is pivotally connected to outside framework and is inlaid in the outside framework, and the upset inner frame can be opened service ports, so that the maintenance of ceiling inside.The inner frame of this service ports framework generally by screw on outside framework, need screw off screw during unlatching, operate cumbersome.Be that solution framework opens the problem of inconvenience, occur at present a kind ofly at outside framework snap close being set, at inner frame the button lock buckle structure of button is set, the interaction by button and snap close realizes the unlatching of service ports and sealed.Though its keying operation of this button lock buckle structure is more convenient, complex structure, manufacturing cost is than higher.

The utility model content

The purpose of this utility model is at the problems referred to above, provides a kind of simple in structure, easily manufactured, cost is low and unlatching, the closed procedure bright posture framework of ceiling service ports easily.

For achieving the above object, the utility model adopts following technical scheme: the bright posture framework of a kind of ceiling service ports, comprise outside framework and the inner frame that is embedded in described outside framework, described inner frame by pivot knuckles on outside framework, be provided with the snap close pin in inner frame outside vertical away from hinged end, this snap close pin is loaded in the snap close pin-and-hole of described inner frame arranged outside, the one end stretches out and is provided with from described inner frame bottom margin screws structure, the other end is bent to form the snap close end, and being provided with slotted eye at described outside framework correspondence position, described snap close end can screw in described slotted eye and screw out.

Owing on inner frame, be provided with the snap close pin, by being screwed in slotted eye, the snap close pin locks, and being screwed out slotted eye, the snap close pin realizes opening, the keying of service ports is easy to operate, and it is simple in structure, easy to manufacture, can reduce manufacturing cost greatly.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Please read Fig. 1, Fig. 2 and Fig. 3, the bright posture framework of ceiling service ports of the present utility model, comprise outside framework 1 and the inner frame 2 that is embedded in described outside framework 1, described inner frame 2 is hinged on the outside framework 1 by pivot 3, be provided with snap close pin 4 in inner frame 2 outside vertical away from hinged end, this snap close pin 4 is loaded in the snap close pin-and-hole of described inner frame 2 arranged outside, the one end stretches out and is provided with from described inner frame 2 bottom margins screws structure 9, the other end is bent to form snap close end 5, and being provided with slotted eye 6 at described outside framework 1 correspondence position, described snap close end 5 can screw in described slotted eye 6 and screw out.

Referring to Fig. 3, described slotted eye 6 lower limbs are the slope that screw terminal is low, the locking end is high, are convenient to snap close end 5 and enter slotted eye 6, have projection 12 at the middle part, slope, skid off slotted eye 6 to prevent snap close end 5.Be provided with reinforced sheet 8 on the outside framework 1 of described slotted eye 6 positions, have on the reinforced sheet 8 and the identical hole of described slotted eye 6 shapes, reinforced sheet 8 can increase the intensity of slotted eye, increases by 6 application lifes of slotted eye.

As shown in Figure 4, the described structure 9 of screwing is for a word screw that is provided with in snap close pin 4 ends is begun to speak, Philip's head screw is begun to speak or knob.

Referring to Fig. 1, Fig. 5, described snap close pin-and-hole is to be connected in described inner frame 2 by the fastener 10 that coats described snap close pin 4 to form, and it is simple in structure, and is easy to install.Position at described snap close pin 4 contiguous described fasteners 10 edges is provided with annular groove 11, and is provided with the projection 12 that snaps in described annular groove 11 at fastener 10 edges, and the structure that prevents snap close pin 10 axial motions that annular groove 11 and projection 12 constitute is processed, installs more convenient.

Described pivot 3 is movably connected on described outside framework 1, is convenient to the installation of inner frame and outside framework.

With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment the protection domain that all any improvement done based on the utility model or modification all belong to the utility model claim.
