[0002] During the maintenance and testing of communication systems in civil aircraft, professionals need to conduct systematic functional verification of the pilot's handheld microphone. First, high-precision measuring equipment is used to monitor the operating current and power supply voltage of the built-in audio amplifier in real time to ensure that its operating parameters strictly meet the equipment's technical specifications and prevent signal distortion or equipment failure due to abnormal current or voltage. At the same time, professional testing instruments are used to perform functional tests on the push-button intercom switch, focusing on verifying its switching performance, including key indicators such as contact resistance when conducting, insulation performance when disconnecting, and response time. This ensures that the switch can achieve reliable signal transmission control and circuit isolation during pressing and releasing, providing a solid guarantee for flight communication safety.

[0003] Existing test benches lack protective mechanisms on their control panels. Specifically, exposed components such as VOLUME switches, ammeters, and voltmeters on the control panels are not equipped with impact-resistant protection structures, which may cause damage to the exposed components during handling and carrying. Therefore, we need to propose a test bench for pilot handheld microphones. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] The pilot handheld microphone test stand includes: a test stand body 1, with a reserved mounting cavity 2 on one side, an operation panel 3 inside the mounting cavity 2, and a protective cover 4 on one side of the operation panel 3. By setting the cooperation structure between the protective cover 4 and the mounting cavity 2, when the protective cover 4 is closed, it can tightly cover the VOLUME switch, ammeter, voltmeter and other components on the operation panel 3, thereby achieving the effect of preventing the exposed components from being damaged by environmental factors or accidental collisions.

[0028] The test stand body 1 incorporates a highly integrated circuit design and miniaturized components, significantly improving its convenience and effectively reducing its size. This addresses the issues of low integration, large size, and inconvenience associated with traditional pilot handheld microphone test stands. The input audio signal is processed and amplified by the circuitry before being output through a speaker. A spare interface is also included for easy portability and flexible adaptation to different scenarios, thus resolving problems such as insufficient verification of key performance indicators.

[0029] When testing the pilot's handheld microphone, insert the 28V and 220V power plugs into the socket, turn on the 28V power switch on the rear control panel 3, connect the handheld microphone jack to the test bench, short-circuit the GND and MV(-) connectors, short-circuit the V(+) and MV(+) connectors, and turn on the VOLUME switch. During the test, press the handheld microphone button to turn on the internal power supply. At this time, a clear voice can be heard, and the ammeter and voltmeter will display readings. Release the button to turn on the microphone, and the ammeter and voltmeter readings will return to zero, and the voice will be interrupted.

[0030] The rotating component 5 is located at the bottom of the test bench body 1, and the movable end of the rotating component 5 is connected to the protective cover plate 4. The storage slot 6 is located at the bottom of the test bench body 1. After the protective cover plate 4 is opened by the rotating component 5, it can be snapped into the inside of the storage slot 6. The rotating component 5 allows the protective cover plate 4 to rotate and open around the bottom of the test bench body 1. When opened, the protective cover plate 4 can be snapped into the storage slot 6, preventing the protective cover plate 4 from shaking randomly or occupying extra space. This not only makes it convenient for operators to adjust the components of the operation panel 3, but also keeps the structure neat during the test and improves the ease of operation.

[0031] The positioning block 7 is fixedly connected to the top of the test bench body 1. An insert block 8 is inserted into one side of the positioning block 7. The insert block 8 is fixedly connected to the protective cover plate 4. A locking component 9 is provided on the top of the positioning block 7 for quickly clamping the protective cover plate 4.

[0032] The rotating assembly 5 includes a fixed rod 501, which is fixedly connected to the bottom of the test bench body 1. A connecting rod 502 is rotatably connected to the fixed rod 501. One end of the connecting rod 502 is fixedly connected to the protective cover plate 4. By setting the rotating connection structure between the fixed rod 501 and the connecting rod 502, the operator can rotate the connecting rod 502 to drive the protective cover plate 4 to open and close around the bottom of the test bench body 1, which can quickly carry out the test operation, while ensuring that the rotation process of the protective cover plate 4 is smooth and stable.

[0033] A slot 10 adapted to the insert block 8 is provided on one side of the positioning block 7. One end of the insert block 8 is inserted into the inside of the slot 10. By setting the insertion structure of the positioning block 7, the insert block 8 and the slot 10, when the protective cover plate 4 is closed, the insert block 8 can be accurately inserted into the slot 10, providing basic positioning for the locking component 9 to be locked, thus achieving the effect of initially fixing the protective cover plate 4 and ensuring the accurate docking of the locking component 9.

[0034] The locking assembly 9 includes a positioning shell 901, which is fixedly connected to the top of the positioning block 7. A locking block 902 is slidably inserted into the bottom of the positioning shell 901. The bottom end of the locking block 902 passes through the positioning block 7 and is inserted into the interior of the insertion block 8. A spring 903 is fixedly connected to the top of the locking block 902. The top end of the spring 903 is fixedly connected to the inner top of the positioning shell 901.

[0035] It also includes a pull rod 904, which is slidably inserted into the interior of the positioning shell 901. The bottom end of the pull rod 904 passes through the positioning shell 901 and is fixedly connected to the top of the locking block 902. By setting a spring 903 to drive the locking block 902 into the positioning groove 11, and cooperating with the wedge-shaped part 12 and the inclined surface locking structure of the positioning groove 11, the operator can pull the pull rod 904 to drive the locking block 902 out of the positioning groove 11, thus achieving automatic locking of the protective cover 4 by the spring force, and quick unlocking by the pull rod.

[0036] The top of the insert block 8 is provided with a positioning groove 11, and the bottom of the locking block 902 is provided with a wedge-shaped part 12 that is adapted to the positioning groove 11. The wedge-shaped part 12 is inserted into the interior of the positioning groove 11.

[0037] A clearance groove 13 adapted to the insertion block 8 is provided on one side of the storage slot 6. The insertion block 8 is snapped into the interior of the clearance groove 13. By setting the matching structure between the storage slot 6 and the clearance groove 13, the protective cover 4 can be completely embedded in the bottom of the test platform body 1 after it is opened, which achieves the effect of preventing the protective cover 4 from shaking randomly or occupying extra space after it is opened, and improving the cleanliness of the operating space.

[0038] It also includes a lifting handle 14, which is fixedly installed on the top of the test bench body 1. By setting the lifting handle 14, the operator can lift or move the test bench body 1 by the handle, thereby optimizing the portability of the equipment and facilitating the movement of the equipment during field operations.

[0039] Working principle: When the test bench body 1 needs to be used, the operator first pulls the lever 904 upward, which drives the locking block 902 to compress the spring 903 and disengage from the positioning groove 11 of the insert block 8, thereby releasing the locking component 9 from locking the protective cover plate 4; then, by rotating the connecting rod 502 of the rotating component 5, the protective cover plate 4 is rotated around the fixed rod 501, and the protective cover plate 4 is locked into the storage groove 6, exposing the operation panel 3 for testing.

[0040] After the test is completed, the protective cover 4 is removed from the storage slot 6 and reset to the outside of the operation panel 3 by rotating the assembly 5, so that the insert 8 is inserted into the slot 10 of the positioning block 7. At this time, the pull rod 904 is released, and the spring 903 resets and drives the wedge-shaped part 12 of the locking block 902 to insert into the positioning slot 11 of the insert 8, thus locking the protective cover 4. Throughout the process, the rotating assembly 5 realizes the opening, closing and storage of the protective cover 4, the positioning block 7 and the insert 8 cooperate to provide initial positioning, and the locking assembly 9 realizes the automatic locking of the protective cover 4 through the spring 903 and the locking block 902. The lifting handle 14 facilitates the handling of the equipment, thus forming a complete workflow of "convenient opening and closing, stable storage and protective handling", effectively protecting the exposed components on the operation panel 3 and improving the practicality of the equipment.
