Description

Technical Field

[0001] The utility model belongs to the technical field of aviation engine packaging box sealing, in particular to a sealing strip structure of an aviation engine packaging box. Background Art

[0002] At present, the sealing strips of the sealed packaging boxes of aircraft engines mostly adopt mushroom head (umbrella) structure and P-type structure, and their molding process adopts one-piece molding process. The structure of the sealing strip is solid structure or hollow structure, such as Figure 1 、 Figure 2 shown.

[0003] When a solid structure is compressed and deformed, the rubber material in the center has no room to deform and can only be squeezed to the sides, causing the rubber strip to be subjected to greater extrusion and shear forces, making it easy for the rubber strip to crush or crack, making it difficult to achieve the expected service life requirements. Although a hollow structure has a deformable space, when the rubber strip is compressed and deformed, the internal space becomes smaller and the pressure increases. The pressure is even greater when affected by external temperature, and the rubber strip is subjected to unnecessary internal forces, resulting in the rubber strip life also failing to meet the expected service life requirements.

[0004] In this regard, the present application proposes a sealing strip structure for an aviation engine packaging box. Utility Model Content

[0005] The utility model aims to provide a sealing strip structure for an aviation engine packaging box to solve the problems in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a sealing strip structure for an aircraft engine packaging box, comprising a sealing strip, the sealing strip being a hollow structure and forming an inner cavity, a pressure relief hole being provided on one side of the sealing strip, the pressure relief hole being communicated with the inner cavity of the sealing strip, a box cover sealing platform and a box bottom sealing platform being provided above and below the sealing strip respectively, a groove being provided on the top surface of the box bottom sealing platform, and the sealing strip being arranged inside the groove.

[0007] Preferably, the pressure relief hole is arranged on the side of the packaging box where the internal pressure is high.

[0008] Preferably, the sealing strip is a mushroom head structure or a P-type structure.

[0009] Preferably, the box cover sealing platform and the box bottom sealing platform are fixed by screws.

[0010] The utility model has at least the following beneficial effects:

[0011] The utility model provides a sealing strip structure for an aviation engine packaging box. By improving the sealing strip structure, the pressure in the internal space of the sealing strip is balanced with the internal pressure of the box body, eliminating the force exerted on the strip by the pressure difference, greatly improving the sealing performance of the product, and increasing the service life of the sealing strip.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] Example

[0020] See also Figure 3 、 Figure 4 and Figure 5 The utility model provides a technical solution: a sealing strip structure for an aircraft engine packaging box, including a sealing strip. The sealing strip is a hollow structure and is formed with an inner cavity. A pressure relief hole 1 is provided on one side of the sealing strip, and the pressure relief hole 1 is communicated with the inner cavity of the sealing strip. A box cover sealing platform 2 and a box bottom sealing platform 3 are respectively provided above and below the sealing strip. A groove 4 is provided on the top surface of the box bottom sealing platform 3. The sealing strip is arranged inside the groove 4. The pressure relief hole 1 is arranged on the side with high pressure inside the packaging box. The sealing strip is a mushroom head structure or a P-type structure. The box cover sealing platform 2 and the box bottom sealing platform 3 are fixed by screws.

[0021] In this embodiment, when the sealing strip is under pressure, there is a deformable space in the middle. When the pressure in the hollow inner cavity of the sealing strip is too high, the pressure is released into the box through the pressure relief hole 1, so that the internal pressure of the sealing strip is balanced with the pressure inside the box. When the sealing strip is used for a long time, the elasticity of the sealing strip decreases and the sealing performance is poor. At this time, the pressure in the packaging box keeps the internal pressure of the strip balanced through the pressure relief hole 1, which is beneficial for the sealing strip to resist compression deformation and achieve a good sealing effect.
