It is used as a test signal source or excitation source when measuring the characteristics and parameters of various telecommunication systems, telecommunication equipment, and components. It has a wide range of applications in production practice and the field of science and technology. In combination with actual use, it is found that when outdoor testing is required, it is necessary to transport the equipment. It is common for the vehicle to be bumped or the microwave signal generator to be hit, causing signal errors or damage. In particular, when used in the testing vehicle, the output or detected signal will jitter or become unstable. Therefore, a microwave signal generator protective device that can reduce shock and buffer is needed for the above-mentioned use environment.

[0003] After searching, it is found that the existing microwave signal generator, such as the announcement number CN214278242U, is called a protective signal generator, including a shell, convex columns are arranged at both sides of the top of the shell, a handle is arranged above the shell through the convex columns, a bottom plate is arranged at the bottom of the shell, a rectangular groove is arranged at the lower end surface of the bottom plate, a pair of fixed columns are arranged at both sides of the shell in the rectangular groove, an adjustable horizontal plate is arranged at the bottom position between the fixed columns, two secondary round rods are arranged at the lower end surface of the horizontal plate, an adjustable main round rod is arranged at the outer circle position of the bottom of the secondary round rod, and a lower pad is arranged at the bottom of the main round rod;

[0004] However, the protective component of the above-mentioned device is located at the bottom, and due to the influence of height during the fall, the device will be offset to a certain extent when it falls to the ground, so that the non-bottom surface touches the ground first, thereby failing to achieve a good shock-absorbing effect; and the existing technology is aimed at shock absorption during the landing process, and the shock absorption effect is not good in "bumpy" conditions. Utility Model Content

[0005] The utility model aims to provide a protection structure for a microwave signal generator, so as to improve the stability of the microwave signal generator during transportation and detection, and avoid damage caused by external collisions.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0007] A protection structure for a microwave signal generator, comprising a main housing for accommodating the microwave signal generator, the protection structure is used for supporting and buffering the microwave signal generator, a corner of the main housing is provided with a corner cut groove, a spring contraction groove is provided at the middle position inside the corner cut groove, used for fixing a shock absorbing spring, and a rubber shock absorbing angle block is fixed to the other end of the shock absorbing spring;

[0008] The rubber shock-absorbing corner block is connected to a limiting guide rod, and the limiting guide rod is sleeved in a guide groove on the angle cutting groove and can be telescopically movable.

[0009] Furthermore, rotating arms are provided on both sides of the front end of the main shell, one end of the rotating arm is rotatably connected to the main shell through a first damping shaft, and the other ends of the rotating arms on both sides are connected through lifting rods.

[0015] Compared with the prior art, the beneficial effect of the utility model is that by installing rubber shock-absorbing corner blocks at the corners of the device, the rubber shock-absorbing corner blocks will touch the ground first when the device accidentally falls, collides, or shakes. After being affected by the impact force, the rubber shock-absorbing corner blocks can slide along the guide grooves on the angle grooves through the limiting guide rods, and shrink and unload the force in the direction of the shock-absorbing spring to reduce the impact on the device itself, solving the problem that the protective components of the existing device are located at the bottom, and the device will be offset to a certain extent when it falls due to the height, so that the non-bottom surface touches the ground first, thereby failing to achieve a good shock-absorbing effect. On the other hand, by arranging a rotatable and inward-retracting U-shaped bracket at the rear end of the device, the rotating support arm can be deflected downward at a certain angle when the device is placed, and the U-shaped bracket at the bottom of the main shell can be turned outward. The U-shaped bracket and the rotating support arm cooperate to support the main shell, so that the main shell has a certain ground clearance to prevent accidental accumulation of water on the table from affecting the main shell.
