[0004] The existing technical solutions in the above have the following defects: communication experiment equipment is highly sensitive to bumps, mainly due to its precise structure, high-frequency signal characteristics, and high-integration design. Communication equipment contains a large number of micron-level precision components, and bumps may cause irreversible damage. High-frequency communication has strict requirements on signal integrity, and slight physical disturbance can cause a cliff-like drop in performance. During the movement and transportation of communication experiment equipment, existing protection equipment mostly only uses plastic pads or foam pads to wrap and protect the bottom and four sides of the communication experiment equipment. However, when the protection box is placed upside down and encounters bumps and vibrations, it is easy to cause damage to the communication experiment equipment. Therefore, we propose an experimental box with gas protection layer to solve the problems mentioned above. UTILITY MODEL CONTENTS

[0006] In order to achieve the above object, the utility model provides the following technical scheme: A kind of experimental box with gas protection layer, including equipment protection device body, the upper end of the equipment protection device body is provided with upper box, the lower end of the equipment protection device body is provided with lower box, flexibly detachable expansion tank is arranged between the upper box and lower box, the number of superposition expansion tank is decided according to the number of equipment carried, the inside of the upper box and the inside of the lower end of expansion tank are provided with protection air cushion mechanism slot, protection air cushion mechanism is installed in the inside of the protection air cushion mechanism slot, the inside of the protection air cushion mechanism is filled with air, protection air cushion mechanism is attached to the surface of communication experiment equipment, and the upper end of communication experiment equipment is protected by shock absorption and pressing when transporting.

[0009] Preferably, the inside of the lower box and the inside of the upper end of the expansion tank are provided with foam protection partitions, a plurality of equipment slots are arranged in the inside of the foam protection partitions, and the communication experiment equipment is arranged in the inside of the equipment slots.

[0010] Preferably, the protection air cushion mechanism comprises pressing air valves, horizontal air inlet air cushions, vertical protection air cushions, horizontal air outlet air cushions, rubber check one-way valves and sealing valves, and the pressing air valves are respectively arranged at the middle positions of the front sides of the upper box and the lower ends of the front sides of the expansion tanks.

[0011] Preferably, one side of the inside of the protection air cushion mechanism slot is provided with a horizontal air inlet air cushion, the horizontal air inlet air cushion and the pressing air valve are sealingly connected by a connecting pipe, the other side of the inside of the protection air cushion mechanism slot is provided with a horizontal air outlet air cushion, the sealing valves are respectively arranged at the middle positions of the rear sides of the box and the lower ends of the rear sides of the expansion tanks, and the sealing valves and the horizontal air outlet air cushions are sealingly connected.

[0013] Compared with the prior art, the utility model has the beneficial effects that:

[0014] 1. The protective air cushion mechanism of this utility model provides shock absorption protection for the upper surface of the communication experimental equipment. In use, after opening the sealing valve of the inflation valve, press the inflation valve again. Pressing the inflation valve allows air to enter the interior of the horizontal air intake air cushion through the connecting pipe, then through the rubber check valve into the interior of the vertical protective air cushion, and finally through the rubber check valve into the interior of the horizontal exhaust air cushion. The air-filled horizontal air intake air cushion, vertical protective air cushion, and horizontal exhaust air cushion adhere to the upper surface of the communication experimental equipment, thus achieving shock absorption protection against pressure. In case of bumps, shaking, or the protective box being overturned... It can also provide good shock absorption protection for communication experimental equipment. At the same time, the rubber check valve can effectively prevent air backflow. When exhaust is required, open the sealing valve and press the horizontal air inlet cushion, vertical protective cushion and horizontal exhaust cushion in sequence to exhaust the protective cushion mechanism. This allows it to fit the upper surface of the communication experimental equipment during the next transport. It solves the problem that most existing protective equipment only wraps the bottom and sides of the communication experimental equipment with plastic pads or foam pads. However, when the protective box is misaligned and placed upside down, it is easy to cause damage to the communication experimental equipment when it is bumped and vibrated.

[0015] 2. During transportation, the communication experimental equipment is placed inside the equipment slot of the foam protective partition. When there are too many communication experimental equipment to fit in the equipment slot of the lower box, an expansion box is installed. The excess communication experimental equipment is placed inside the equipment slot of the expansion box. Multiple expansion boxes can be stacked according to the number of equipment, so as to realize the centralized collection of multiple equipment and avoid the inconvenience of carrying multiple protective boxes during transportation.

[0023] After opening the sealing valve of the press inflation valve 8, press the press inflation valve 8. Pressing the inflation valve 8 will allow air to enter the interior of the horizontal air intake cushion 14 through the connecting pipe 19, and then enter the interior of the vertical protective air cushion 15 through the rubber check valve 17. Finally, it will enter the interior of the horizontal exhaust air cushion 16 through the rubber check valve 17. The horizontal air intake cushion 14, vertical protective air cushion 15 and horizontal exhaust air cushion 16 filled with air will fit against the upper surface of the communication experimental equipment, thereby achieving pressure and shock absorption protection. In the event of bumps or shaking or the protective box being overturned, it can also provide good shock absorption protection for the communication experimental equipment. At the same time, the setting of the rubber check valve 17 can effectively prevent the backflow of air. When it is necessary to exhaust, open the sealing valve 18 and press the horizontal air intake cushion 14, vertical protective air cushion 15 and horizontal exhaust air cushion 16 in sequence to exhaust the protective air cushion mechanism 10, so that it can meet the requirements of fitting the upper surface of the communication experimental equipment in the next transport.

[0024] Please see Figures 1-2 The upper box 2 and the lower box 3 are fixedly connected around their perimeters, as are the upper box 2 and the expansion box 4, and the lower box 3 and the expansion box 4, by locking buckles 6. Sealing edges 5 are provided at the lower end of the upper box 2, the upper end of the lower box 3, and the upper and lower ends of the expansion box 4. The sealing edges 5 are tightly fitted together for a sealed connection. A handle 7 is installed at the middle position of the upper end of the upper box 2.

[0025] Please see Figure 3The interior of the lower box body 3 and the interior of the upper end of the expansion box 4 are both provided with a foam protection partition 12, and a plurality of equipment slots 13 are provided in the interior of the foam protection partition 12, and the communication experiment equipment is arranged in the interior of the equipment slots 13.
