Abstract
A rubber metal connecting accessory for an anti-crash oil tank relates to an oil tank connecting accessory. The connecting accessory comprises a metal plate, rubber coated on the outer edge of the metal plate and an adhesive for bonding the metal plate and the rubber, wherein the rubber is connected with a pipeline joint through a screw sleeve groove arranged on the metal plate and a steel wire screw sleeve embedded in the screw sleeve groove; the helicopter can not be torn and damaged by the deformation tension of the connecting part in the crash state, so that the sealing performance of the oil tank is ensured, and the crash-resistant function of the oil tank is realized.
Description
Technical Field
The utility model relates to an oil tank attachment, in particular to rubber metal attachment for anti crash oil tank.
Background
The crash resistance of the oil tank means that after the helicopter is crashed due to an accident, the sealing performance of the oil tank is not damaged, and fuel oil leakage cannot be generated to cause fire or explosion, so that the life safety of passengers is protected. Because the rubber oil tank is a soft oil tank, the rubber oil tank can meet the functions of oil storage, oil supply and the like only by being connected with a cabin, onboard equipment, pipelines and the like, and the helicopter can be subjected to deformation tension of a connecting part when falling. And the connecting accessories on the rubber oil tank need to meet the connecting function and have the capability of being not torn or damaged by deformation tension, so that the sealing property of the oil tank can be ensured.
The existing oil tank with the anti-crash function adopts a rubber metal connecting accessory, namely a mode of completely surrounding rubber outside a metal plate, and the mode causes the weight of the connecting accessory to be overlarge; the other type of the oil tank adopts a mode that the lining cloth and the rubber are bonded around the metal plate by the compression ring, the deformation tension borne by the rubber metal connecting accessory is small, and the phenomenon that the rubber is separated from the metal plate is easily generated after the rubber metal connecting accessory is stressed, and the two methods are not enough to ensure the sealing performance of the oil tank.
Disclosure of Invention
The utility model aims at providing an anti rubber metal attachment for crash oil tank.
The utility model adopts the technical proposal that: the utility model provides an anti rubber metal attach fitting for crash oil tank, its technical essential is, including metal sheet, cladding rubber on the outer edge of metal sheet, the metal sheet passes through the adhesive with rubber and bonds, and the outer edge outside-in of metal sheet is equipped with waist shape through-hole, strengthening rib and connecting portion in proper order connecting portion on be equipped with the through-hole and encircle the screw shell groove of through-hole, inlay in the screw shell groove and have the steel wire swivel nut.
In the scheme, the opening surfaces of the thread sleeve grooves are on the same sealing plane.
The utility model has the advantages that: the rubber metal connecting accessory for the anti-crash oil tank comprises a metal plate, rubber coated on the outer edge of the metal plate and an adhesive for bonding the metal plate and the rubber, wherein the rubber is connected with a pipeline joint through a screw sleeve groove arranged on the metal plate and a steel wire screw sleeve embedded in the screw sleeve groove; the helicopter can not be torn and damaged by the deformation tension of the connecting part in the crash state, so that the sealing performance of the oil tank is ensured, and the crash-resistant function of the oil tank is realized.

Detailed Description
The above objects, features and advantages of the present invention will be more clearly understood and the present invention will be explained in more detail with reference to the accompanying drawings 1 to 3 and the detailed description thereof.
The rubber metal connecting accessory for the anti-crash oil tank comprises a metal plate 2, coated rubber 3 and an adhesive for vulcanizing and bonding the coated rubber 3 on the outer edge of the metal plate 2, and the connecting accessory and the wall 1 of the oil tank are integrally vulcanized and formed through the coated rubber 3.
The outer edge of metal sheet 2 is gone up outside-in and is equipped with waist shape through-hole 21, strengthening rib 22 and connecting portion 23 in proper order, waist type through-hole 21 is the in-process that carries out the dull and stereotyped vulcanization at the attach fitting through the mould, makes cladding rubber 3 flow through waist type through-hole 21 and bonds, forms integratively, improves the bonding strength of cladding rubber 3 and metal sheet 2, guarantees that the connection position is difficult for tearing and destruction by the tensile force that warp under the helicopter crash state. The reinforcing ribs 22 protrude from the surface of the metal plate 2, and are in the form of protruding vertical walls, so that the strength of the metal plate 2 is improved, and the weight of the metal plate 2 is reduced.
The connecting portion 23 is provided with a through hole 24 and a thread insert groove 25 annularly arranged around the through hole 24, and a steel thread insert 26 is embedded in the thread insert groove 25. The connecting part 23 locks the pipeline joint connected with the connecting part through the screw sleeve groove 25 and the steel wire screw sleeve 26, and the opening surface 27 of the screw sleeve groove annularly distributed around each through hole 24 is on the same sealing plane, so that fuel can circulate and transport through the through holes 24.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
