[0015] 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 the embodiments. Based on the embodiments in 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.

[0016] Reference Figures 1 to 6 The utility model provides a tool storage box for aircraft maintenance, including a box body 2 and a cover body 1. The box body 2 is connected to the cover body 1 by a plurality of hinges. The inner upper wall of the cover body 1 is provided with a plurality of slide grooves 7. A plurality of circular plates 10 are slidably connected in each slide groove 7. Each circular plate 10 is fixedly connected with a plurality of sleeves 8. The sleeve 8 is composed of a plurality of pipes that are sealed and slidably sleeved with each other. When air is pumped into the sleeve 8, the sleeve will stretch. A pressure plate 9 is fixedly connected to one end of the sleeve 8 away from the circular plate 10. When the cover body 1 is covered on the box body 2, the pressure plate 9 squeezes and fixes the tools in the box body 2.

[0017] A hollow sealing ring 3 is provided on the contact surface between the cover body 1 and the box body 2. The sealing ring 3 is fixed to the cover body 1. The sleeves 8 located in the same slide groove 7 are commonly connected to a soft connecting pipe 13. The sealing ring 3 is connected to each connecting pipe 13 through a pipeline. When the cover body 1 is covered on the box body 2, the sealing ring 3 located between the two is squeezed so that the air inside it is squeezed to the sleeve 8 through the connecting pipe 13. The air enters the sleeve 8 and stretches it to make the pressure plate 9 abut against the tool placed in the box body 2, thereby realizing the squeezing and fixation of the tool.

[0018] Reference Figures 1 to 3The cover 1 is fixedly connected with a heightening layer 4, and a handle 5 for holding is rotatably connected to the heightening layer 4, so that the storage box of the utility model is more convenient to take and put. The heightening layer 4 is a hollow structure, and the heightening layer 4 is connected to the sealing ring 3. There is a clear space inside the hollow heightening layer 4, which provides a place for accommodating air, and can produce a buffering effect on the air squeezed into the sleeve 8, reducing the force of the sudden high-pressure air entering the sleeve 8 to cause it to suddenly stretch and hit the tool.

[0019] Reference Figure 1 A pressure relief hole 6 is provided above the increased layer 4. When the air pressure in the increased layer 4 is too high, the air therein will escape through the pressure relief hole 6 to prevent the pressing plate 9 from exerting excessive squeezing force on the tool and causing damage to it. It is particularly noted that a one-way valve is provided at the increased layer 4 or the sealing ring 3. The one-way valve is used to allow external air to enter the increased layer 4 or the sealing ring 3. When a large amount of air in the increased layer 4 or the sealing ring 3 flows out through the pressure relief hole 6, the external air will enter the increased layer 4 or the sealing ring 3 after the cover body 1 is opened, to prevent the air therein from being insufficient to cause the pressing plate 9 to squeeze and fix the tool when the cover body 1 is covered on the box body 2 next time.

[0020] Reference Figure 6 The side wall of the slide groove 7 is fixedly connected with a friction plate 12, and the friction plate 12 is arranged on the side of the slide groove 7 close to the box body 2. When the circular plate 10 is located on the side of the slide groove 7 close to the box body 2, it abuts against the friction plate 12. When the circular plate 10 is located on the side of the slide groove 7 away from the box body 2, it does not contact the friction plate 12. When the side wall of the circular plate 10 is released from the friction plate 12, it can provide obvious friction force to prevent some parts of the circular plate 10 from moving randomly in the slide groove 7.

[0021] A side of the circular plate 10 away from the box body 2 is fixedly connected with an elastic soft pad 11. When the circular plate 10 is subjected to force to squeeze the soft pad 11, the soft pad 11 can be compressed and the circular plate 10 can be disengaged from the friction plate 12. The soft pad 11 itself has elasticity and can cause the circular plate 10 to be disengaged from the friction plate 12, that is, when the position of the circular plate 10 is not adjusted manually, the circular plate 10 will be disengaged from the friction plate 12 to prevent the circular plate 10 from shifting; conversely, when the position of the circular plate 10 is adjusted manually, the sleeve 8 is pressed so that the circular plate 10 squeezes the soft pad 11 until the circular plate 10 is disengaged from the friction plate 12, and the sleeve 8 can be partially displaced easily.

[0022] To sum up: when the storage box of the utility model is in use, tools are placed in the box body 2, the position of the sleeve 8 is adjusted so that the pressure plate 9 is located above the tool, and then the cover body 1 is closed. In the process of closing the cover body 1, the sealing ring 3 will be squeezed, thereby squeezing the air in the sealing ring 3 into each sleeve 8 through the connecting pipe 13. The sleeve 8 stretches and pushes the pressure plate 9 to resist the tool, completing the squeezing and fixing of the tool. At this time, external bumps or shaking of the storage box will not cause the tool to collide in the box body 2, thereby reducing the probability of the tool being damaged by impact in the storage box.

[0023] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
