Description
Technical Field
The utility model relates to a seal structure of metal layer board self-locking nut on aircraft belongs to aircraft structural design field.
Background
The aircraft structure is in order to satisfy the system installation and maintenance demand, need set up a large amount of flaps, and some flaps not only need guarantee aircraft structure rain-proof, requirements such as oil tank sealing, have still participated in aircraft overall structure biography power, so need use a large amount of sealing support plate self-locking nuts to carry out the structural seal.
The existing sealing supporting plate self-locking nuts are various in forms, most of the sealing supporting plate self-locking nuts adopt a sealing cover designed outside a metal supporting plate self-locking nut to meet the sealing requirement, and the sealing cover is made of metal, rubber, nylon and the like. The sealing supporting plate self-locking nut adopting the rubber sealing cover is widely used due to light weight and simple structural form. However, the existing sealing support plate self-locking nut adopting the rubber sealing cover is integrally wrapped, namely rubber is integrally vulcanized outside the metal support plate self-locking nut, when the sealing support plate self-locking nut is fixed, rubber is extruded due to rivet connection, so that crack damage is generated on rubber in a connecting area, the rubber aging can be accelerated by the damage stress, and the sealing performance of the sealing support plate self-locking nut is damaged.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem existing in the prior art and providing an aircraft upper sealing supporting plate self-locking nut structure with good sealing performance and long service life.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a self-locking nut structure of a sealing supporting plate on an airplane comprises a metal supporting plate self-locking nut, a sealing cover and sealant; the metal supporting plate self-locking nut comprises a self-locking nut part and a supporting plate part, and the sealing cover is sleeved on the self-locking nut part and is fixedly sealed with the self-locking nut part through sealing glue; the supporting plate part is sealed with the connecting plate through sealant.
Preferably, the sealing cover is in interference fit with the metal supporting plate self-locking nut.
Preferably, the self-locking nut portion is externally provided with a pattern.
Preferably, the material of the sealing cover is rubber.
Preferably, the height of the seal cover is higher than the axial height of the self-locking nut portion.
Compared with the prior art, the utility model has the advantages of it is following:
1. the sealing support plate self-locking nut is improved on the basis of the existing sealing support plate self-locking nut, a full-wrapping sealing cover is changed into a half-wrapping sealing cover, then the sealing glue is used for carrying out seam inner seam outer sealing to meet the requirement of overall sealing, the damage to rubber caused by rivet connection of the original sealing support plate self-locking nut is avoided, and the sealing performance and the service life of the sealing support plate self-locking nut are guaranteed.
2. If the problems of damage, aging and the like of the sealing cover occur in the using process, the sealing cover can be independently replaced.

Detailed Description
The invention will be further described with reference to the accompanying figures 1-4: as shown in fig. 1-4, a self-locking nut structure of a sealing supporting plate on an airplane mainly comprises three parts: metal layer board self-locking nut 1, sealed cowling 2 and gluing agent 3. The metal supporting plate self-locking nut 1 is a double-lug metal supporting plate self-locking nut, the end part of the metal supporting plate self-locking nut is extruded to be deformed, and the metal supporting plate self-locking nut has a self-locking function through thread deformation; the sealing cover 2 is made of rubber through vulcanization, the sealing cover 2 is sleeved on the metal supporting plate self-locking nut 1 and is tightly fixed and sealed with the metal supporting plate self-locking nut 1 through an adhesive 3 to form a sealing supporting plate self-locking nut; sealing of other parts is achieved through the sealant 4, when the sealing supporting plate self-locking nut is installed, the joint surface of the sealing supporting plate self-locking nut and the connecting plate is coated with the sealant 4 to seal in the joint with the connecting plate 6, and after the installation is completed, the periphery of the sealing supporting plate self-locking nut and the head of the rivet are coated with the sealant to seal outside the joint.
As shown in fig. 3-4, in actual use, the metal supporting plate self-locking nut and the rubber sealing cover are assembled to be used as a standard part or a finished product, when the assembled sealing supporting plate self-locking nut is installed, sealant is coated on the joint surface of the metal supporting plate self-locking nut and the connecting plate 6 to perform seam internal sealing, and after the installation is completed, the sealant is coated on the periphery of the sealing supporting plate self-locking nut and the rivet joint to perform seam external sealing. In order to ensure that the binding surface of the metal supporting plate self-locking nut and the rubber sealing cover is sealed, the sealing cover and the metal supporting plate self-locking nut need interference fit, adhesive is firmly bonded, patterns can be processed outside the metal supporting plate self-locking nut on the binding surface, the adhesive bonding surface is increased, and sealing is ensured.
The structure is suitable for the double-lug sealing supporting plate self-locking nut, the single-lug sealing supporting plate self-locking nut and the butterfly sealing supporting plate self-locking nut, and only the metal supporting plate self-locking nut is correspondingly changed when the structure is used.
