Description

Technical Field

[0001] The utility model belongs to the field of assembly connection in aviation manufacturing technology, and relates to a connecting device for aircraft rolling wave ducts. Background Art

[0002] For most of the internal ventilation system ducts (environmental control system, fuel system, engine system) on the aircraft, the duct orifices adopt the form of rolling waves, and flexible connection is used between two ducts, that is, a combination of a rubber hose and two (or four) stainless steel clamps for connection and fixation. After connection, it is required that the length of the rubber hose, the distance between the duct orifices, and the distance between the edge of the fixed clamp and the edge of the rubber hose should all meet the specification requirements. Otherwise, the duct installation needs to be adjusted again. Due to the influence of human factors (most of the rubber hoses are still manually cut, and some ducts in the environmental control system use purchased fixed-length rubber hoses), the situation that does not meet the above requirements often occurs, and the rubber hose has come off in some areas with strong vibration, affecting the safety of the aircraft.

[0003] When cutting the rubber hose manually, the length of the rubber hose is likely to deviate; after cutting, the end face of the rubber hose is uneven, affecting the installation position of the clamp; after connection, the distance between adjacent duct orifices cannot be measured and controlled, and it can only be "touched" and "felt" to meet the requirements; when the distance between the duct orifices is too large or too small, this connection form is not applicable. When the distance between the duct orifices is too large, the duct is easy to come out, and when the distance between the duct orifices is too small, it is difficult to connect and install the duct; after this flexible connection is installed for a long time, adhesion will occur and it is very difficult to disassemble.

[0021] A detailed description of an aircraft rolling wave conduit connecting device of the utility model is given in conjunction with the attached drawings:

[0022] An aircraft rolling wave conduit connecting device includes a housing 1, a corrugated half pipe 2, a hinge 3, a spring buckle 4, and a hook 5; the housing 1 is semi-cylindrical, with the corrugated half pipe 2 fitting inside. One side of the two housings 1 is connected by a hinge 3, and the two ends of the other side are respectively connected by a cooperation of a spring buckle 4 and a hook 5 to form a cylindrical structure.

[0023] Further, it also includes a rubber pad 6, and the rubber pad 6 is pasted on the inner sides of both ends of the corrugated half pipe 2. The rubber pad can compensate for the gap between the corrugated half pipe and the conduit, and improve the sealing performance of the pipeline.

[0024] Further, the pasting adhesive is specifically XY-401 adhesive. This adhesive is a commonly used material in industry, has good viscosity, and is not easy to fall off after pasting.

[0025] Further, the rubber pad 6 is composed of a sponge rubber plate. The sponge rubber plate has good elasticity and strong sealing performance.

[0026] Further, the middle part of the cylindrical structure is connected by cooperating a spring buckle 4 with a hook 5. It can strengthen the connection of the corrugated half pipe 2, prevent the offset at the butt joint of the corrugated half pipe, and cause leakage.

[0027] Further, the corrugated half pipe 2 and the housing 1 are fixed by spot welding. After welding, the deformation and stress of the corrugated half pipe 2 and the housing 1 are small, the structure is firm, and the offset is prevented.

[0028] Further, the inner wall shape of the corrugated half pipe 2 matches the outer wall of the conduit. The straight part of the corrugated half pipe 2 can be closely attached to the outer wall of the conduit, improving the sealing performance of the conduit.

[0029] Further, preferably, the two corrugated half pipes 2 are non-uniform semi-cylinders. The two corrugated half pipes 2 are buckled together to form a partial lap joint, further improving the sealing performance at the connection of the conduit.

[0030] Further, the width of the hinge 3 should match the width of the housing 1. It can ensure that the outer shapes of the two housings 1 do not deviate.

[0031] Usage method of the rolling wave conduit connection device:

[0032] 1) Before connecting two rolling wave conduits, first align the adjacent conduit pipe orifices so that the rolling wave protrusions on the conduits are within the range of the corrugated half pipe 2 of the connection device;

[0033] 2) First make one side housing 1 of the rolling wave conduit connection device contact the rolling waves at the ends of the two conduits, so that the rolling wave protrusions at the conduit ends fall into the depressions of the corrugated half pipe 2 of the rolling wave conduit connection device;

[0034] 3) Close the other side housing 1 of the rolling wave conduit connection device so that the depressions of the corrugated half pipe 2 cover the rolling wave protrusions on the conduit;

[0035] 4) For the rolling wave conduit connection device with two non-uniform semi-cylindrical corrugated half pipes 2, first make the longer corrugated half pipe 2 fit the rolling wave protrusions on the conduit, and then close the other corrugated half pipe 2 so that the two corrugated half pipes 2 are buckled together to form a partial lap joint.

[0036] 5) Then lock the spring buckle 4 and the hook 5 in the middle of the rolling waveguide connection device.

[0037] 6) Finally, lock the spring buckle 4 and the hook 5 at both ends of the rolling waveguide connection device.
