Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of component fixing, especially relates to a nail sticking, heat insulation and sound insulation device and airplane. BACKGROUND

[0002] The installation mode of the heat insulation and sound insulation layer of a civil aircraft is changed from the initial form of cooperating with a tape by a nylon fastener to the form mainly using structural frames, stringers and gaskets and secondarily using a nylon fastener, which greatly improves the maintenance and repairability of the heat insulation and sound insulation layer. However, when selecting the adhesive for the nail sticking on the structural frame, the tensile force from the heat insulation and sound insulation layer is mainly considered, and the force generated by the deformation of the aircraft structure itself is not fully considered. Since the nail sticking is made of nylon material and the base thereof is relatively smooth, the adhesive force is affected, so that the nail sticking on the aircraft structural frame may be caused to be peeled off from the adhesive due to the deformation occurring in the flight or the process of translocation. The vibration in the flight process may aggravate the falling of the nail sticking in the passenger cabin without the installation of interior panels.

[0003] To solve the above problems, in the prior art, the adhesive is continuously applied along the upper surface and the lower surface of the nail base so that an envelope can be formed after the adhesive is solidified. Although the application area of the adhesive is optimized, the amount of the adhesive is increased, for example, one tube of adhesive can be used for 60 nail stickings, and now one tube of adhesive can only be used for 45 nail stickings, the increased weight of the adhesive is increased by 33% compared with the original weight of the adhesive. Moreover, the time for applying the adhesive is also increased, for example, the old scheme requires 7.30 seconds for the installation of each nail sticking, and the installation is completed by two persons. The new scheme requires 12.86 seconds for the installation of each nail sticking, and the installation is completed by two persons. The total number of the nail stickings of the whole aircraft is 3373, and the increase of the single aircraft is (12.86-7.30)*3373 / 3600 seconds, which is about 10.4 hours, and the influence of the working station rhythm is about 10.4 / 2=5.2 hours. The weight and the cost of the aircraft are increased, and the processing speed and the rhythm of the aircraft are delayed. UTILITY MODEL CONTENTS

[0029] In the description of the embodiment, the terms "on", "under", "right", etc. Orientation or positional relationship is based on the orientation or positional relationship shown in the drawing, only for the convenience of description and simplification operation, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore cannot be understood as a limitation on the utility model.In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0030] In the prior art, the glue gun is used to continuously apply glue along the upper surface and the lower surface of the nail base, so that the glue can form an envelope after solidification.Although the existing method optimizes the application area of the adhesive, this method will increase the amount of glue, for example: one tube of glue can be used for 60 nails, and now one tube of glue can only be used for 45 nails, the increased glue weight increases by 33% compared with the original glue weight;And the glue application time will also increase accordingly, for example: the old scheme needs 7.30 seconds to install an average of each nail, and is completed by two people;The new scheme needs 12.86 seconds to install an average of each nail, and is completed by two people.3373 nails are installed on the whole machine, and the single machine increases (12.86-7.30)*3373 / 3600 seconds, about 10.4 hours), the working position beat is affected about 10.4 / 2=5.2 hours;The weight and cost of the aircraft are increased, and the processing speed and beat of the aircraft are delayed.

[0031] To solve the above problems, the utility model provides a kind of aircraft, including heat insulation sound insulation device. Wherein heat insulation sound insulation device includes structure frame and nail. Wherein, refer toFigure 1 and Figure 2 Further, the adhesion nail comprises a nail seat 10 and a nail rod 20, the nail seat 10 is fixed to the structure frame by the adhesive. Further, the thermal and sound insulation device further comprises a thermal and sound insulation layer and a base, the nail rod 20 can penetrate the thermal and sound insulation layer and is clamped to the base by the gasket. The aircraft realizes good thermal and sound insulation function by using the thermal and sound insulation device, and the thermal and sound insulation device avoids the adhesion nail from being separated from the structure frame due to the force generated by the deformation of the structure itself and the vibration in the flight process by using the adhesion nail, thereby improving the safety in the flight process.

[0032] Further, the nail seat 10 is provided with a through hole 11, the central axis of the through hole 11 is the same as the central axis direction of the nail seat 10; the nail rod 20 extends along the central axis direction of the nail seat 10 and is arranged at the geometric center of the nail seat 10; the adhesive is applied on the side of the nail seat 10 away from the nail rod 20, and the adhesive can overflow from the edge of the nail seat 10 and adhere to the side wall of the nail seat 10 when being extruded, and the adhesive can also overflow from the through hole 11 and adhere to the side wall of the through hole 11 and form a raised glue block in the through hole 11. By arranging the through hole 11 on the nail seat 10, the weight of the adhesion nail is reduced, thereby reducing the weight of the aircraft; the adhesive is only applied on the side of the nail seat 10 away from the nail rod 20, which not only reduces the amount of adhesive used, but also improves the application speed, saves the processing cost, improves the processing speed and rhythm; the adhesive can overflow from the through hole 11 and adhere to the side wall of the through hole 11 and form a raised glue block in the through hole 11, thereby increasing the adhesion of the adhesion nail.

[0033] In the prior art, the nail seat is square, and the nail rod is arranged at the geometric center of the square nail seat. Due to the uneven distance between the nail rod and the edge of the nail seat, the force on the edge of the nail seat is uneven, and the part far away from the nail rod, such as the corner of the nail seat, will be separated from the adhesive first, thereby reducing the bearing force of other parts of the adhesion nail, and the reliability of the adhesion nail is low. In the embodiment, the nail seat 10 is circular. The distance between the edge of the circular nail seat 10 and the nail rod 20 is the same, and the force is uniform, thereby improving the adhesion of the adhesion nail.

[0034] Further, the through hole 11 is provided with a plurality of through holes. In order to increase the contact area between the adhesive and the nail seat 10 and the number of protruding glue blocks. Considering the rigidity of the nail seat 10, in the embodiment, the through hole 11 is three, and the three through holes 11 are distributed in a triangular shape. The triangular distribution is relatively stable, and the adhesion of the adhesion nail is further improved. Further preferably, the triangle is an equilateral triangle, and the equilateral triangle takes the nail rod 20 as the center of gravity. The equilateral triangle causes the distance between the three through holes 11 and the nail rod 20 to be the same, the force on the three through holes 11 is uniform, the force stability of the adhesion nail is improved, and the adhesion of the adhesion nail is increased. In the embodiment, the diameter of the through hole 11 is 30 mm.

[0035] Further, in order to avoid increasing the weight of the adhesive nail, the material of the nail seat 10 and the nail rod 20 is nylon. Nylon is a kind of high-performance engineering thermoplastic linear polyamide, which has high mechanical strength, good fatigue resistance, impact resistance and corrosion resistance, and excellent electrical insulation performance; compared with metal nails, nylon nails are lighter in weight and higher in wear resistance.

[0036] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present application.
