Description

Technical Field

[0001] The utility model relates to the field of packaging box structures, in particular to a sealed aviation engine packaging box observation port structure. Background Art

[0002] An aircraft engine packaging box is a box for packaging aircraft engines. After the aircraft engine is sealed and packaged, a humidity indicator will be placed in the box to detect the humidity inside the box. In order to facilitate the viewing of the humidity indicator, the traditional method is to open a hole in the molded composite box and then glue an organic transparent plate on it, which can facilitate observation while achieving the sealing of the packaging box.

[0003] However, during the long-term transportation of the packaging box, the adhesive joints of this observation port structure are easily subject to the vibration of the packaging box, resulting in tiny cracks, which in turn causes air leakage in the packaging box and loss of its sealing function. At the same time, the organic transparent plate of this observation port structure cannot be disassembled, and the humidity indicator in the packaging box needs to be replaced by unpacking. The entire replacement process is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0004] The purpose of the utility model is to provide a sealed observation port structure for an aircraft engine packaging box, which can improve the sealing performance at the observation port and avoid air leakage during long-term transportation of the packaging box.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] refer to Figure 1-5 A sealed aircraft engine packaging box observation port structure is provided on one side of the packaging box body 1. The packaging box body 1 has an observation port on one side. A fixed shell 3 is coaxially provided on the observation port. The fixed shell 3 is detachably provided with an observation plate 4. The observation plate 4 can be quickly disassembled, and the humidity indicator can be quickly replaced without unpacking. The whole process is fast, convenient and efficient.

[0024] A sealing device 5 is provided between the fixed shell 3 and the observation plate 4 to improve the sealing performance at the observation port and avoid air leakage during long-term transportation of the packaging box body 1 .

[0025] In some embodiments, the fixed shell 3 includes a shell 31, which is fixedly connected to the packaging box body 1. A mounting groove 32 is provided on the side of the shell 31 away from the packaging box body 1. A through hole 33 is provided at the bottom of the mounting groove 32. The through hole 33 is connected to the inside of the packaging box body 1. An observation panel 4 is provided on the cover of the through hole 33. The observation panel 4 can be a transparent acrylic panel. The indication of the humidity indicator in the packaging box body 1 can be observed through the observation panel 4 and the through hole 33.

[0026] In some embodiments, the packaging box body 1 and the fixed shell 3 are integrally formed, and the fixed shell 3 can be pre-embedded and demoulded with the composite material packaging box body 1 to avoid human errors in the subsequent manual opening of the observation port, which may affect the sealing performance at the observation port.

[0027] In some embodiments, at least three fixing rings 2 are provided on the connecting surface between the fixing shell 3 and the packaging box body 1, and the diameters of the three fixing rings 2 gradually decrease along the observation plate 4 toward the inside of the packaging box body 1, which can increase the connection area between the fixing shell 3 and the packaging box body 1, thereby enhancing the connection strength between the fixing shell 3 and the packaging box body 1, and further improving the sealing performance at the observation port.

[0028] In some embodiments, at least three screw holes 34 are provided at the bottom of the mounting groove 32, and the three screw holes 34 are distributed in a ring shape. At least three mounting holes 41 are provided on the observation plate 4, and the mounting holes 41 correspond to the screw holes 34 one by one. Bolts can be used to pass through the mounting holes 34 and be screwed together with the screw holes 34, so as to realize the detachable connection between the observation plate 4 and the fixed shell 3.

[0029] In some embodiments, the sealing device 5 includes a first sealing ring groove 51 and a second sealing ring groove 52. The first sealing ring groove 51 is coaxially arranged on the side of the mounting groove 32 close to the observation plate 4, and the second sealing ring groove 52 is coaxially arranged on the side of the observation plate 4 close to the mounting groove 32. A sealing ring 53 is arranged between the first sealing ring groove 51 and the second sealing ring groove 52. The diameter of the sealing ring 53 is greater than the depth when the first sealing ring groove 51 and the second sealing ring groove 52 are pressed together. When the observation plate 4 is installed on the fixed shell 3, the observation plate 4 squeezes the sealing ring 53 to deform, filling the gap between the first sealing ring groove 51, the second sealing ring groove 52 and the gap between the first sealing ring groove 51 and the second sealing ring groove 52, thereby ensuring the sealing performance between the observation plate 4 and the fixed shell 3.

[0030] In some embodiments, the three screw holes 34 are distributed in an annular shape outside the first sealing ring groove 51, which can avoid air leakage caused by the installation holes 34 when the observation plate 4 and the fixed shell 3 are installed, thereby ensuring the sealing performance.

[0031] In some embodiments, the shell 31 may be a truncated cone, the mounting groove 32 may be a coaxial conical groove, and the diameter of the mounting groove 32 facing outward is larger than the diameter of the mounting groove 32 facing the inside of the packaging box body 1, which can increase the operating space and facilitate operation.

[0032] The specific working principle is as follows:

[0033] The indication of the humidity indicator in the packaging box body 1 is observed through the observation plate 4. When it is observed that the humidity indicator needs to be replaced, the bolts are loosened, the observation plate 4 is removed from the fixed shell 3, and the humidity indicator is replaced through the through hole 33. After the replacement is completed, the packaging box body 1 is in a set state, and the through hole 33 is covered with the observation plate 4, so that the two ends of the sealing ring 33 are respectively arranged in the first sealing ring groove 51 and the second sealing ring groove 52, so as to achieve the initial positioning of the observation plate 4 on the fixed shell 3, and a plurality of bolts are used to pass through the plurality of mounting holes 34 respectively and screw them with the corresponding screw holes 34, and the bolts are tightened to achieve the rapid replacement of the humidity indicator.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
