Description

Technical Field

[0001] The utility model relates to the technical field of aviation cabinets, and particularly relates to a plastic aviation cabinet. Background Art

[0002] An aviation cabinet, also known as a cargo container, is a standardized container used for loading and protecting precision instrument equipment during long-distance transportation. It is mainly developed to solve the problems that traditional simple wooden box packaging transportation cannot effectively protect high-tech products during long-distance transportation and has poor mobility. Especially during the transportation of high-tech equipment such as stage lighting equipment, medical instrument equipment, audio-visual system multimedia, optoelectronic industry, and military equipment, aviation cabinets have been widely used.

[0003] However, in practical applications, there are still some defects in existing aviation cabinets:

[0004] 1. Most existing aviation cabinets have a square structure.

[0005] 2. An aviation cabinet usually includes a box body and door covers on both the front and back sides of the box body. Most of the existing door covers are internally connected to the box body to form a single placement space. Items such as the chassis of equipment, wires, microphones, and lighting lamps are all placed together, which not only makes the inside of the aviation cabinet messy but also makes it easy for small items to collide with the equipment chassis.

[0006] 3. A fixing rack is usually arranged inside the aviation cabinet, which is mainly used to fix the equipment chassis to prevent it from shifting during transportation. However, the existing fixing racks are usually in fixed positions and cannot be adjusted according to the size of the equipment, resulting in poor applicability. Summary of the Utility Model

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0035] As Figure 1 shown, the present utility model provides a plastic aviation cabinet, including a box body 1. Cover bodies 2 are arranged at both the front and rear ends of the box body 1. Placing cavities are arranged inside both the box body 1 and the cover bodies 2. The placing cavity of the box body 1 is mainly used for placing a chassis, while the placing cavity of the cover body 2 can place small items such as microphones, wires, and lighting lamps. A door cover 3 is movably arranged on the side of the cover body 2 close to the box body 1. The door cover 3 separates the placing cavities of the box body 1 and the cover body 2, thereby avoiding collision with the chassis inside the box body 1.

[0036] As Figure 3 shown, two door covers 3 are symmetrically arranged on the side of the cover body 2 close to the box body 1. Connecting blocks 31 are arranged at both ends of one side of the door cover 3. First connecting grooves 21 are arranged around the cover body 2. The connecting blocks 31 are in clearance fit with the first connecting grooves 21, so that the door cover 3 can be flipped relative to the cover body 2, and thus the door cover 3 can be opened or closed.

[0037] As Figure 4As shown in the figure, at both ends of the side of the door cover 3 away from the connecting block 31, mounting openings 32 are provided. A connecting buckle 6 is slidably connected at the mounting opening 32. A second connecting groove 22 is provided on the inner wall of the cover body 2 corresponding to the position of the connecting buckle 6. One end of the connecting buckle 6 is provided with an inserting strip 61. A lifting plate 63 is also provided on the connecting buckle 6. By pulling the lifting plate 63, the connecting buckle 6 can be driven to slide along the mounting opening 32. When it is necessary to close the door cover 3, the inserting strip 61 of the connecting buckle 6 can be inserted into the second connecting groove 22, thereby fixing the door cover 3. When it is necessary to open the door cover 3, the inserting strip 61 of the connecting buckle 6 can be pulled out from the second connecting groove 22. At this time, the door cover 3 can rotate relative to the cover body 2, thereby opening the door cover 3.

[0038] Preferably, a toothed plate 33 is provided at the mounting opening 32. One end of the connecting buckle 6 is provided with a snap plate 62. The snap plate 62 can be engaged with any position of the toothed plate 33, thereby fixing the position of the connecting buckle 6. At the same time, a baffle 34 is provided at the outer end of the toothed plate 33. The baffle 34 can limit the moving range of the snap plate 62 to prevent the connecting buckle 6 from moving out of the mounting opening 32.

[0039] As Figure 5 shown, a fixing frame 4 is provided in the placing cavity of the box body 1 of this embodiment. The installation position of the fixing frame 4 can be adjusted relative to the size of the placed device. The fixing frame 4 specifically includes a first fixing plate 41 and a second fixing plate 42 provided around the inner circumference of the box body 1. The first fixing plate 41 extends along the width direction of the box body 1 and is connected to the inner wall of the box body 1 through fasteners, thereby further strengthening the internal structure of the box body 1. Even if multiple box bodies 1 are stacked, they can be stably supported. A plurality of connecting holes 43 are provided at both ends of the first fixing plate 41. The connecting holes 43 are arranged at intervals along the first fixing plate 41. The second fixing plate 42 is an L-shaped structure. The second fixing plate 42 extends along the height direction of the box body 1. The second fixing plate 42 can select connecting holes 43 at different positions for fixing according to the size of the chassis placed inside the box body 1. The L-shaped side of the second fixing plate 42 can be connected to two consecutive connecting holes 43 in the upper and lower two first fixing plates 41 through fasteners. At the same time, the other L-shaped side can abut against the four sides of the chassis, thereby fixing the chassis.

[0040] Preferably, to solve the problem that the top corners of the aviation cabinet are easily damaged, the four surrounding top corner edges of the cover body 2 of this embodiment are recessed inward to form a top corner strengthening structure 5. The top corner strengthening structure 5 is preferably an outer arc shape, and the arc middle part of the top corner strengthening structure 5 and the cover body 2 connected to both ends of the arc are on the same straight line, increasing the force-bearing area, thereby preventing the collision force from concentrating on a single point of the top corner. When the top corner strengthening structure 5 is collided, the top corner strengthening structure 5 will have multiple force-bearing points in contact at the same time, thereby dispersing the collision force and making the top corner not easily damaged.

[0041] AsFigure 2 As shown, a plurality of third connection grooves 11 are provided on the outer surface of the box body 1. An anti-slip plate 7 can be embedded in the third connection groove 11. The height of the anti-slip plate 7 is twice the depth of the third connection groove 11. Therefore, the anti-slip plate 7 protrudes from the outer surface of the box body 1. When the box body 1 is placed on the ground, the anti-slip plate 7 contacts the ground first, thereby preventing the box body 1 from rubbing against the ground and causing damage. Anti-slip patterns are also provided on the anti-slip plate 7, which can play an anti-slip role. At the same time, when multiple aviation cabinets are placed simultaneously, the box bodies 1 can be stacked vertically. Only one anti-slip plate 7 needs to be placed in the third connection grooves 11 close to each other on two box bodies 1. The anti-slip plate 7 can fix the upper-layer aviation cabinet. This placement method is not only stable but also can save placement space.

[0042] At the same time, compared with the anti-slip plates of existing aviation cabinets, most of the existing anti-slip plates are made of EVA foam. Although EVA foam also has certain anti-slip performance, after long-term use, EVA foam is very easy to be dented under the extrusion of heavy objects, resulting in a decline in wear resistance. To solve this technical problem, the box body 1, the cover body 2, and the anti-slip plate 7 of the present utility model are preferably made of PE plastic material, which has stronger wear resistance and can be used for a long time.

[0043] Specifically, reinforcing ribs 8 are also provided inside the box body 1 of this embodiment. The reinforcing ribs 8 include a plurality of transverse reinforcing ribs and longitudinal reinforcing ribs. The transverse reinforcing ribs are arranged at intervals along the length direction of the box body 1, and the longitudinal reinforcing ribs are arranged at intervals along the width direction of the box body 1, so that the transverse reinforcing ribs and the longitudinal reinforcing ribs intersect with each other. The reinforcing ribs 8 of this embodiment adopt an intersecting structural design. Compared with the traditional single-direction reinforcing ribs, the aviation cabinet of this embodiment has stronger supporting performance.

[0044] Specifically, convex blocks 12 are provided at both the front and rear ends of the box body 1 of this embodiment. Fourth connection grooves 23 are opened at one end of the cover body 2 away from the apex angle strengthening structure 5. The convex blocks 12 can be embedded in the fourth connection grooves 23 to initially position the cover body 2. At the same time, lock catches 91 are provided at both ends of the box body 1, and lock catch mounting seats 92 are provided at both ends of the side of the cover body 2 close to the box body 1. The lock catches 91 can be buckled on the lock catch mounting seats 92 to secondarily fix the cover body 2. For convenient transportation, a handle 10 is also installed on one side of the box body 1 of this embodiment, so that the staff can lift the aviation cabinet.

[0045] It should be noted that the above specific embodiments are only the preferred embodiments of the present utility model and the technical principles applied. Those skilled in the art should understand that various modifications, equivalent replacements, changes, etc. can also be made to the present utility model. However, as long as these transformations do not depart from the spirit of the present utility model, they should be within the protection scope of the present utility model. In addition, some terms used in the specification and claims of this application are not restrictive, but are only for the convenience of description.
