They are used for the transfer of bomb disposal personnel or the disposal of suspicious explosives, the security of important places of activity, and the proactive protection of major events. Currently, frequency jammers at home and abroad are divided into vehicle-mounted (high-power equipment), portable (medium and small power equipment), special equipment (for specific objects), etc. according to different power levels. Users purchase different types of equipment according to different needs and applications.

[0003] In the prior art, a Chinese patent document with patent number CN212980071U proposes a vehicle-mounted frequency jammer, including a vehicle body and a limit bin, wherein a cabinet and a main body are sequentially arranged inside the vehicle body from bottom to top, and a roof platform is fixed on the top of the vehicle body, and a first antenna is supported by a main frame, so that the cabinet can control the switch of each module in the jamming device when connected to a wired remote control panel, which is convenient for the driver to operate, and some communication channels are released for internal use in an emergency. However, in actual use, due to different usage scenarios, the transmission power of the jammer is also different, and the transmission power is one of the key factors affecting the interference range of the frequency jammer. Generally speaking, the greater the transmission power, the stronger the interference signal generated by the jammer, so that it can cover a wider area.

[0014] (III) Beneficial effects Compared with the prior art, the present invention provides a vehicle-mounted frequency jammer, which has the following beneficial effects: 1. The interferometer operating table is quickly installed in the vehicle body through the installation component. When the vehicle is driving, the buffer component effectively reduces the vibration impact of the vehicle on the interferometer during driving, improves the working stability of the equipment, and at the same time ensures that the use of the interferometer will not be affected by the shaking of the vehicle when the vehicle is driving, thereby increasing the use range of the interferometer.

[0015] 2. This vehicle-mounted frequency jammer installs the jammer operating table in the vehicle body, rotates and connects the jammer operating table with the mounting table, pushes the jammer operating table, and adapts the mounting plate at the bottom of the jammer operating table to the clamping groove on the mounting table, so that the jammer operating table and the mounting table can be closely fitted, and at the same time, the upper cover plate is pressed to make the upper cover plate and the lower cover plate close to each other, and multiple groups of guide rods on the lower cover plate are in contact with the adapted holes on the upper cover plate, so as to ensure the precise fit between the lower cover plate and the upper cover plate, and at the same time, when the lower cover plate and the upper cover plate are close to each other, the telescopic rod and the guide cylinder can be close to each other, and at the same time, the two ends of the contact rod are The contact rods respectively slide and rotate under the guidance of the first guide groove and the second guide groove. When the contact rod rotates 180 degrees under the guidance of the first guide groove and the second guide groove, the two ends of the contact rod can fall into the limit grooves respectively. At this time, there is still a partial gap between the lower cover plate and the upper cover plate. At the same time, when the lower cover plate and the upper cover plate shake up and down due to the driving of the vehicle body, the elastic force of the buffer spring can achieve an elastic buffering effect between the lower cover plate and the upper cover plate under the guidance of the telescopic rod, thereby increasing stability, avoiding shaking and deviation, and effectively reducing the impact of vibration during vehicle driving on the equipment, protecting the normal operation of the interferometer, and extending the service life of the equipment.

[0016] 3. For this type of vehicle-mounted frequency jammer, when it is necessary to separate the lower cover and the upper cover, it is only necessary to press the upper cover to bring the lower cover and the upper cover closer to each other, so that the two ends of the contact rod are separated from the limit groove under the elastic force of the buffer spring, that is, the contact rod is rotated 180° in the opposite direction to complete the reset, and at the same time, the upper cover is pulled to separate the lower cover and the upper cover, thereby completing the rapid disassembly of the jammer operating table and improving the disassembly effect and speed.

[0017] 4. For this type of vehicle-mounted frequency jammer, under the action of external force, the moving plate drives the synchronous plate to slide, and the driving wheel and the driving plate cooperate to generate rotational motion. When the synchronous plate on one side moves, the driving wheel can drive the synchronous plate on the other side to move in the opposite direction. By evenly distributing the force on one side to the two reset springs, the buffering effect can be effectively improved. At the same time, the setting of the counterweight block can further balance the torque change during movement. The sliding plate is adapted to the groove on the jammer operating table to provide a buffer stroke, thereby ensuring that vibration is absorbed and the equipment remains stable when the vehicle is driving.

[0018] 5. When the height of the support column is adjusted during use, the support column can drive the mounting ring to rise and fall synchronously when it rises, so that the mounting groove drives the driving plate to deflect around the axis of the rotating rod, and then drives the flip plate to rotate around the axis of the rotating rod. At the same time, the rotating plate can rotate around the axis of the rotating rod driven by the flip plate. When the trigger plate contacts the trigger rod, the trigger plate is an arc structure with gradually increasing height and deflected to one side, so that the rotating plate can rotate around the axis of the connecting rod, thereby ensuring that the opening degree of the rotating plate is different when the support column is at different heights, thereby adjusting the air intake space in the vehicle to optimize the operating environment of the jammer and ensure stability during use.

[0019] 6. For this type of vehicle-mounted frequency jammer, when the vehicle shakes during driving, the movable plate moves. When the movable plate moves, it can also drive the trigger arm on its top to move, thereby causing the limit cylinder and the trigger arm to deflect relative to each other, thereby driving the deflection plate to rotate around the axis of the rotating rod. The limit cylinder has a groove-shaped structure, which can always maintain relative rotation with the trigger arm, thereby ensuring smooth rotation of the deflection plate. The wavy structure of the deflection plate can effectively improve the air circulation effect in the vehicle body, thereby improving the heat dissipation effect during the use of the jammer, ensuring the heat dissipation effect of the vehicle body when using the jammer during driving, and ensuring the use environment of the jammer.
