Abstract
The utility model provides a can dismantle cloud shape lock connection structure of flap, the hollow rivet of assembly on the flap that contains the screw, matches with the screw to and fix the fixed spring on the mouth frame, its characterized in that hollow rivet's middle part have an annular arch, cup jointed a compression spring on the screw, when this cloud shape lock lock status, compression spring is in a compression state, in case and the unblock, the lower end of screw has broken away from fixed spring's constraint, restoring to the throne under the effect of compression spring, the upper end of screw leaves hollow rivet, makes things convenient for the flap class can dismantle the installation and the dismantlement of part.
Description
Technical field
The utility model relates to a kind of mechanical connecting structure of aircraft manufacturing, specifically a kind of cloud shape lock construction for connecting detachable lid.
Background technology
At present, cloud shape lock is widely used in fixed cover lid on aircraft, the isostructural connection of wheel backplate and floor, existing cloud shape lock is made up of with the fixing spring be fixed on mouthful frame (wire spring) and through the screw that pipe rivet is connected with fixing spring the pipe rivet be fixed in lid (knockdown pieces) substantially, but in actual use, screw length usually because selecting is improper with the spring heights being used for fixing it, the technical requirements of Yun Xingsuo is departed from when adding mounting spring, cause and cannot differentiate whether Yun Xingsuo opens, even if sometimes open, but because the spring installed departs from screw openings axis, screw also cannot take off, when multiple cloud shape lock is particularly installed in a lid, if one of them cloud shape lock is not opened, lid will be caused to pull down, can only dismantle by force with spiral shell cutter, not only destroy lid but also delayed maintenance, efficiency is very low.
Summary of the invention
The object of the present invention is to provide a kind of cloud shape lock connection structure of detachable lid, this structure conveniently can distinguish opening or locking states of Yun Xingsuo.
A kind of cloud shape lock construction of detachable lid, containing screw, with the pipe rivet be assemblied in lid of screw mates, and the fixing spring be fixed on mouthful frame, it is characterized in that there is an annular projection at the middle part of described pipe rivet, screw is socketed with a Compress Spring.
The beneficial effect of the application is, the annular protrusion in the middle part of pipe rivet is utilized to be blocked by the Compress Spring be socketed on screw, when this cloud shape lock locking state, Compress Spring is in a kind of compressive state, and once unlock, the lower end of screw has departed from the constraint of fixing spring, under the reset response of Compress Spring, make the upper end of screw leave pipe rivet, significantly demonstrate this Yun Xingsuo and open.Facilitate the installation and removal of the detachable part of lid class.
Below in conjunction with embodiment accompanying drawing, the application is described in further detail.
Accompanying drawing explanation
Fig. 1 is a kind of cloud shape lock connection structure signal of detachable lid
Number description: 1 screw, 2 pipe rivets, 3 lids, 4 mouthfuls of frames, 5 fixing springs, 6 Compress Springs, 7 annular protrusions
Detailed description of the invention
See accompanying drawing, a kind of cloud shape lock construction of detachable lid, containing screw 1, with the pipe rivet 2 be assemblied in lid 3 of screw mates, and the fixing spring 5 be fixed on mouthful frame 4, there is an annular protrusion 7 at the middle part of described pipe rivet 2, and screw 1 is socketed with a Compress Spring 6.During the locking of cloud shape lock, Compress Spring 6 compresses by the upper end of screw 1 and the annular protrusion 7 of pipe rivet, the lower end of screw 1 is by the constraint of the fixing spring 5 be fixed on mouthful frame, lid and mouth frame is made to be in a kind of close-connected state, when needing to open cloud shape lock dismounting lid 3, rotary screw 1, removes the constraint of fixing spring 5 pairs of screw lower ends, Compress Spring 6 releases energy, and makes screw upper end eject pipe rivet and is convenient to remove.
