Abstract

The utility model relates to a frame structure for ceiling inspection and repair opening. The frame structure comprises a quadrate outer frame and a quadrate inner frame, one side of which can be inserted in the outer frame in a rotating mode, a button which is arranged on the inner frame and a breech lock body which is arranged on the outer frame. The button is a pushing rod whose upper end is provided with a stopping sliding block. The breech lock body is a triangle buckling tongue which is provided with a sliding rod. The outlying rotating edge of the inner frame and the opposite lateral surface of the outer frame are a groove, and the upper groove edge of the groove is a buckling conjunction claw part which is meshed with the triangle buckling tongue. The pushing rod of the button is placed in the hole of the lower groove edge. A fixed block with a through hole is arranged on the lateral surface of the outer frame in relation to the groove, and the sliding rod of the breech lock body passes out of the outer frame and is provided with a stopping block piece. A resetting spring positioned between the triangle buckling tongue and the outer frame is sheathed on the sliding rod. The frame structure for ceiling inspection and repair opening of the utility model realizes the convenient switching of the inner frame through the design of a self-locking button.

Description

The frame construction that is used for the ceiling access hole

Technical field

The utility model relates to the mounting structure of ceiling access hole, particularly a kind of frame construction that is used for the ceiling access hole.

Background technology

At present, the frame construction of ceiling access hole comprises inside casing and housing, housing is fixed on the keel of ceiling, inside casing is entrenched in the housing rotationally, close so that conveniently open when needed, still, inside casing is by being bolted on the housing, must turn on or swivel bolt just can be opened inside casing, operation is very inconvenient during use.

Summary of the invention

The purpose of this utility model is, a kind of frame construction that is used for the ceiling access hole is provided, and this structure realizes inside casing switch easily by a locking press button.

For achieving the above object, the frame construction that is used for the ceiling access hole provided by the utility model, comprise: square housing and inside casing, one side of described inside casing is rotatable to be entrenched in the housing, comprise that also one is installed in button and on the inside casing and is installed in breech lock body on the housing, described button is the push rod that the upper end has limited slip block; Described breech lock body is the triangle block tongue that an end has slide bar;

Described inside casing away from rotate the limit and with housing side in opposite directions be a groove, the last trough rim of this groove is the fastening claw that meshes with the triangle block tongue, assigns the push rod of button in the hole of following trough rim;

One fixed block that has a through hole is set on the side of described housing with respect to groove, and the slide bar of breech lock body is provided with a stop tab after passing housing in the through hole, the resetting spring of suit one between triangle block tongue and housing on the slide bar.

When shutting inside casing, limited slip block freely hangs at following trough rim, and the formed fastening claw of the triangle block tongue of breech lock body and last trough rim meshes together; When desiring to open inside casing, upwards promote push rod, by the through hole of the limited slip block on the push rod with triangle block tongue propelling fixed block, separate with last trough rim, inside casing falls.

As a kind of improvement of the present utility model, a fixed block that has guide rail that is used for fixing push rod is set in the groove of described inside casing, guarantee when promoting push rod more stable.

As another kind of improvement the of the present utility model, correspondence is provided with L shaped locating slot and locating piece between the right angle of described inside casing and housing, makes that contact is more firm between inside casing and the housing.

Advantage of the present utility model is, the frame construction that is used for the ceiling access hole of the present utility model by the design of a locking press button, has realized inside casing switch easily.

The specific embodiment

Further specify structure of the present utility model and use below in conjunction with accompanying drawing 1-4.

As Figure 1-3, the left side of inside casing 2 is rotatable to be entrenched in the housing 1, and button 3 push rods 6 assign into down in the hole of trough rim 17, and the lateral surface on inside casing 2 the right is a groove, and the last trough rim 16 of this groove is for fastening claw 9; Fix a fixed block that has a through hole 11 on the lateral surface of housing 1 with respect to groove, the slide bar 7 of breech lock body 4 passes housing 1 back and fixes a stop tab 10 with a flat head screw in the through hole 11, goes back suit one resetting spring 12 on the slide bar 7.

When shutting inside casing 2, limited slip block 5 freely hangs on following trough rim 17, and the triangle block tongue 8 and the last trough rim 16 formed fastening claws 9 of breech lock body 4 mesh together; When opening inside casing 2, upwards promote push rod 6, the limited slip block 5 by push rod 6 upper ends advances the through hole 11 of fixed blocks with triangle block tongue 8, and triangle block tongue 8 embeds these fixed block recesses, and separates with last trough rim 16, and inside casing 2 falls.

In this example, the groove floor of inside casing 2 is fixed a fixed block that has a guide rail 13, is used for fixing the push rod 6 that is inserted in the guide rail 13, is provided with L shaped locating slot 14 at the place, right angle of housing 1, and correspondence is provided with L shaped locating piece 15 at the place, right angle of inside casing 2.

When installing and using framework provided by the utility model, as shown in Figure 4, can housing be fixed on the keel of ceiling with housing intermediate plate 18, when desiring to open ceiling, need only upwards touch push rod 6, inside casing 2 just can fall in that action of gravity is sagging, and it is very convenient to operate.
