Description

Technical Field

[0001] The present application relates to the technical field of aviation boxes, and in particular to an aviation aluminum alloy box. Background Art

[0002] Aviation boxes are a new type of packaging product that was created to address the problem that traditional simple wooden box packaging and transportation cannot effectively protect high-tech products during long-distance transportation and have poor mobility. The most commonly used material is aluminum alloy.

[0003] Because the scenario in which it is used requires movement, when the aviation box contains heavy objects, the portable aviation box is relatively bulky; and in some scenarios, when it is not convenient to set casters for the aviation box to roll, the pull-rod aviation box (similar to a suitcase) is not convenient to directly lift and carry; for this reason, we designed an aviation aluminum alloy box that is easy to switch between lifting or pushing modes.

[0008] As a preference, the corresponding upper cover body and the first limiting frame and the second limiting frame are formed with avoidance grooves, and the end of the rod body is manually retracted to allow the roller to move toward the center of the end of the rod body to escape from the loading and unloading groove.

[0009] Preferably, two movable rods are symmetrically arranged at the end of the rod body, and both of the movable rods slide along the axial direction of the end of the rod body. A spring is arranged on the inner side of the movable rod and fixedly connected to the inner wall of the end of the rod body; the roller is connected to the outer end of the movable rod through a bearing.

[0028] Example:

[0029] Reference Figure 1-7The present embodiment proposes an aviation aluminum alloy box, including an upper box 1 and a lower box 4 that are detachably connected. For example, the upper box 1 and the lower box 4 are fixed by a zipper or a plurality of spring buckles 6. A pull rod assembly 2 is provided on the top of the upper box 1. The pull rod assembly 2 is symmetrically designed. The pull rod assembly 2 is detachably and slidably provided with a first rod 9 and a second rod 11 at both ends of its symmetry plane. The first rod 9 and the second rod 11 are connected by two hinge shafts in the middle. When the two hinge shafts are lifted from the middle, the first rod 9 and the second rod 11 gather toward the middle to form a lifting structure. One of the rods is removed from its mounting end and straightened toward the other side to form a push-pull structure. The present embodiment realizes that, through the setting of a pull rod assembly 2, it has two practical functions of lifting and pushing, and is very convenient to use. As needed, the user can use a pull rod assembly 2 when the aviation box is heavier. Figure 3 The aviation aluminum alloy box can be moved by pushing and pulling; when it is inconvenient to push and pull the aviation aluminum alloy box, Figure 2 The lifting mode.

[0030] The following is a preferred embodiment of a pull rod assembly 2: the pull rod assembly 2 includes a first limit frame 8 and a second limit frame 10, the first rod body 9 and the second rod body 11 slide in the first limit frame 8 and the second limit frame 10 respectively, and the first rod body 9 and the second rod body 11 are provided with rollers 20 at their installation positions so that the angle of the first rod body 9 and the second rod body 11 can change when sliding.

[0031] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the first limiting frame 8 and the second limiting frame 10 are both provided with a long groove for limiting and rolling the roller 20, as shown in FIG. Figure 6 As shown, the long slot actually has an end point on the inner side of the limit frame, which allows the two rods on both sides to form a more suitable lifting angle in the lifting mode. The long slot is formed with a loading and unloading groove 18 at the end position of the corresponding rod, and the height of the loading and unloading groove 18 is greater than or equal to the height of the roller 20; the first rod 9 and the second rod 11 both include a rod end 17, which is an elastic telescopic structure, and is in an elastically stretched state in the initial state, so that the rod end 17 can be stably located in the long slot and roll. Figure 7 As shown, the corresponding upper cover body and the first limiting frame 8 and the second limiting frame 10 are formed with an avoidance groove 19 , and the rod end 17 is manually retracted to allow the roller 20 to move toward the center of the rod end 17 to escape from the loading and unloading groove 18 .

[0032] like Figure 4 , Figure 5As shown, two movable rods 14 are symmetrically arranged at the end 17 of the rod body. Both movable rods 14 slide along the axial direction of the end 17 of the rod body. A spring 16 is arranged inside the movable rod 14 and fixedly connected to the inner wall of the end 17 of the rod body (it can be fixed directly or connected with a bearing); the roller 20 is connected to the outer end of the movable rod 14 through a bearing. The inner end of the movable rod 14 is provided with an adjustment portion 15. The top of the adjustment portion 15 extends out of the top surface of the end 17 of the rod body, and an adjustment groove for adjustment is formed on the top surface. Since the adjustment portion 15 is as shown in FIG. Figure 4 As shown, the movable rod 14 can no longer rotate in the adjustment groove. If you want the movable rod 14 to be able to rotate relative to the adjustment portion 15, you need to install another bearing. Of course, the movable rod 14 does not necessarily have to be able to rotate relative to the end face of the rod body.

[0033] The rod end 17 has receiving grooves 21 at both ends, and the roller 20 is received in the receiving grooves 21 when it is retracted. It is worth noting that after the roller 20 and the movable rod 14 are connected, the rod end 17 is a part of the first rod 9 or the second rod 11, and can be initially Figure 4 As shown, when the first rod body 9 and the second rod body 11 slide on the corresponding limit frames, the rod body end 17 cannot rotate relative to the first rod body 9 or the second rod body 11. This is achieved by connecting the roller 20 and the movable rod 14 with bearings, so that the roller 20 cooperates with the first rod body 9 and the second rod body 11 to slide, but the roller 20 is still limited inside the long groove.

[0034] In order to strengthen the aviation aluminum alloy box, protective parts 3 are fixedly installed at the corners of the upper box 1 and the lower box 4. The material of the protective part 3 is rubber or aluminum alloy, which can provide buffering and replace the box itself to rub against the ground.

[0035] A caster 5 is provided at the bottom of the lower box body 4. The caster 5 has a brake pad 7. When the pull rod assembly 2 is switched to a push-pull structure, it can be pushed or pulled to facilitate the movement of the aviation box.

[0036] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the attached claims and their equivalents.
