Detailed implementation manners

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Figure 1 A perspective view of a cylindrical part 100 is schematically shown. The cylindrical part 100 may be a missile cabin part. The cylindrical part 100 is a hollow cylinder. The cylindrical part 100 includes a cylindrical outer surface 102, a cylindrical inner surface 104, and a main body 106 extending between the outer surface 102 and the inner surface 104. The outer surface 102 has a first diameter, and the inner surface 104 has a second diameter smaller than the first diameter. The main body 106 of the cylindrical part 100 may include a plurality of openings 108. The cylindrical part 100 may be made of aluminum alloy. Although the aluminum alloy material has certain mechanical strength, it is still easily damaged during transportation, and it is not easy to fix the missile cabin part with a plurality of openings 108.

[0031] To solve the above problems, as Figure 1 , Figure 2 , Figure 3 and Figure 4 , this embodiment provides a protective device 200, including: an outer support part 210, an inner support part 240, a first buffer structure 220, and a second buffer structure 230.

[0032] The outer support portion 210 has a slotted groove. The inner support portion 240 is disposed in the slotted groove, and a receiving groove 211 is formed between the outer wall 236 of the inner support portion 240 and the inner wall of the slotted groove. The cross-sectional shape of the receiving groove 211 is annular, the inner diameter of the annulus corresponds to the second diameter, and the outer diameter of the annulus corresponds to the first diameter.

[0033] The first buffer structure 220 is disposed at a position of the outer support portion 210 close to the receiving groove 211. There is a certain distance between the first buffer structure 220 and the outer wall of the receiving groove 211, so as to ensure that the outer wall of the receiving groove 211 is a complete wall surface, facilitating uniform support for the outer wall of the missile cabin part.

[0034] The second buffer structure 230 is disposed at a position of the inner support portion 240 close to the inner wall of the receiving groove 211. There is a certain distance between the second buffer structure 230 and the inner wall of the receiving groove 211, so as to ensure that the inner wall of the receiving groove 211 is a complete wall surface, facilitating uniform support for the inner wall of the missile cabin part.

[0035] During fixation, the missile cabin part in a cylindrical shape can be placed in the receiving groove 211. The outer wall 236 of the inner support portion 240 can support the inner wall of the missile cabin part, and the inner wall of the slotted groove can support the outer wall 236 of the missile cabin part. The missile cabin part can be well fixed by the inner and outer support methods, with simple operation, stable and effective.

[0036] During transportation, the missile cabin part will inevitably be jolted. When the missile cabin part shakes, the first buffer structure 220 can buffer the outer wall of the missile cabin part, and the second buffer structure 230 can buffer the inner wall of the missile cabin part, slowing down the shaking trend of the missile cabin part, and at the same time not exerting too much pressure on the missile cabin part to avoid deformation of the missile cabin part.

[0037] Such as Figure 3As shown, in this embodiment, the first buffer structure 220 includes first buffer holes 214 provided on the outer support portion 210. A plurality of first buffer holes 214 are arranged around and at intervals at a position on the outer wall of the outer support portion 210 close to the receiving groove 211. The second buffer structure 230 includes second buffer holes 234 provided on the inner support portion 240. A plurality of second buffer holes 234 are arranged around and at intervals at a position on the inner wall of the inner support portion 240 close to the receiving groove 211. The first buffer holes 214 can buffer the outer wall of the missile cabin part, and the second buffer holes 234 can buffer the inner wall of the missile cabin part. The plurality of first buffer holes 214 and the plurality of second buffer holes 234 can cope with the situation where the missile cabin part sways in different directions. The first buffer holes 214 and the second buffer holes 234 can overcome the swaying tendency of the missile cabin part through deformation and recovery. The inner support portion 240 as a whole will not sway, and the outer support portion 210 as a whole will not sway, which can play a good fixing role and limit the swaying and floating of the missile cabin part to the minimum.

[0038] As Figure 3 shown, in this embodiment, the first buffer holes 214 and the second buffer holes 234 extend in the height direction. For example, the height dimension can be greater than the length of the missile cabin part, or the two are equal, so as to provide a uniform buffer effect.

[0039] As Figure 3 shown, in this embodiment, the cross-sectional shape of the first buffer hole 214 is one of a triangle, a rectangle, and a semi-circle. The first buffer holes 214 with the above shapes all have good buffer effects.

[0040] As Figure 3 shown, in this embodiment, the cross-sectional shape of the second buffer hole 234 is one of a triangle, a rectangle, and a semi-circle. The second buffer holes 234 with the above shapes all have good buffer effects.

[0041] As Figure 3 shown, in this embodiment, the bottom of the receiving groove 211 has a bottom plate 205, and the bottom plate 205 can carry the missile cabin part.

[0042] In this embodiment, the materials of the outer support portion 210, the inner support portion 240, and the protective cylinder are expandable polyethylene, which is also called polyethylene foam, EPE pearl cotton.

[0043] As Figure 3 shown, in this embodiment, the outer support portion 210, the inner support portion 240, and the bottom plate 205 are integrally formed.

[0044] As Figure 3As shown, in this embodiment, the cross-sectional shape of the slotted opening is circular, the cross-sectional shape of the inner support portion 240 is circular, and the inner diameter of the slotted opening is greater than the outer diameter of the inner support portion 240.

[0045] As Figure 5 As shown, in this embodiment, the outer support portion 210 has a plurality of slotted openings distributed in a matrix, and a plurality of inner support portions 240 are respectively disposed in the corresponding slotted openings, thus forming a plurality of protective devices 200, which can simultaneously accommodate and fix a plurality of missile compartment parts, improving the transportation efficiency.

[0046] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the appended claims.
