Technical Field
[0001] This utility model relates to the field of equipment protection technology, specifically to the housing protection structure of a portable wireless monitoring receiver for civil aviation. Background Technology
[0002] In the civil aviation sector, portable wireless monitoring receivers are widely used as important monitoring equipment in scenarios such as airport ground communication monitoring and signal monitoring during flight takeoff and landing. Because they need to be frequently carried to different locations for operation, and the working environments are complex and diverse, including areas around airport runways and aprons, these places often present various potential collision risks and harsh environmental factors.
[0003] In the complex environment of an airport, there may be various sharp objects on the ground, such as metal fragments and stones. When the receiver is placed on the ground, the bottom casing can easily come into contact with these objects, causing scratches or damage. Once the bottom casing is damaged, it will not only affect the appearance of the receiver, but more importantly, it may expose the internal circuitry. Receivers are usually equipped with multiple interfaces, and during transport, dust, sand, and other debris can easily enter the interfaces. Once the debris enters the interfaces, it will contaminate the interfaces and internal circuitry. Therefore, a protective structure for the casing of a portable wireless monitoring receiver for civil aviation is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a protective shell structure for a portable wireless monitoring receiver for civil aviation, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective structure for the housing of a portable wireless monitoring receiver for civil aviation, including a wireless monitoring receiver body for civil aviation radio monitoring, wherein corner protectors are fixed at all four corners of the wireless monitoring receiver body; The bottom of the wireless monitoring receiver body is provided with a detachable shielding component, which is used to prevent scratches on the bottom of the wireless monitoring receiver body. The wireless monitoring receiver body has several interfaces on one side, and a protective component is provided on one side of each interface for shielding and protecting the interface. The shielding component includes a metal plate, and screw holes are provided at all four corners of the metal plate; The protective assembly includes a transparent cover and a locking mechanism. A rotating shaft is fixedly inserted into one side of the transparent cover, and a connecting frame is rotatably connected to the outside of the rotating shaft. A protrusion is fixed to one side of the connecting frame.
[0006] Preferably, a limiting groove is provided at the bottom of the corner protector located at the bottom of the wireless monitoring receiver body, and the metal plate is adapted to the inside of the limiting groove.
[0007] Preferably, the inner side of the screw hole is connected to the corner guard by bolts, and the metal plate is located at the bottom of the wireless monitoring receiver body.
[0008] Preferably, the locking mechanism includes a connecting rod, and a locking block is fixed to one side of the connecting rod; A sliding groove is provided on one side of the transparent cover plate, and a sliding rod is fixed to the inner wall of the sliding groove.
[0009] Preferably, the wireless monitoring receiver body has an insertion slot on one side of its back, and a limit block is fixed to the inner wall of the insertion slot. The protrusion is bolted to one side of the wireless monitoring receiver body.
[0010] Preferably, when the locking block is inserted into the insertion slot, the transparent cover is in a closed state, and when the locking block leaves the insertion slot, the transparent cover is in an open state.
[0011] Preferably, the outer side of the slide rod slides through one side of the connecting rod, and the connecting rod is fixed with a slider located on the outer side of the transparent cover plate; A spring is sleeved on the outside of the slide rod, and the two ends of the spring are respectively connected to one side of the connecting rod and the slide groove.
[0012] Preferably, a handle is installed on one side of the wireless monitoring receiver body, and heat dissipation holes are provided on both sides of the wireless monitoring receiver body.
[0013] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects: 1. When the operator carries the wireless monitoring receiver by the handle, the corner guards fixed at the four corners can directly resist the edge bumps that may occur during the carrying process, effectively preventing the outer shell of the wireless monitoring receiver from being deformed or damaged due to impact. When the wireless monitoring receiver needs to work in a complex environment, the metal plate prevents the shell from being scratched or punctured by sharp objects, playing an important protective role.
[0014] 2. When the protective components are in the closed state, the sealing ring adhered to the inner wall of the transparent cover tightly clamps between the transparent cover and the wireless monitoring receiver body, sealing the gap between them and preventing external dust and sand from entering the wireless monitoring receiver body through the interface gap during transport, thus protecting the interface and internal circuitry from contamination. When the interface on one side of the wireless monitoring receiver body needs to be used, the operator only needs to push the slider located on the outside of the transparent cover upwards, which will cause the connecting rod to slide along the slide bar in the groove, disengaging the locking block from the limit block and releasing the transparent cover from its locked state. The transparent cover can then be rotated around the pivot to fully expose the interface, facilitating cable connection, preventing foreign objects from entering during transport, and ensuring stable equipment performance.

[0020] Example Please see Figure 1-5This utility model provides a technical solution: a protective shell structure for a portable wireless monitoring receiver for civil aviation, including a wireless monitoring receiver body 1 for civil aviation radio monitoring, with corner guards 2 fixed at each of the four corners of the wireless monitoring receiver body 1; the wireless monitoring receiver body 1 is used to monitor the civil aviation VHF communication frequency band (108-137MHz), investigate potential radio interference around the airport, and ensure the normal operation of aviation communication and navigation systems. It also monitors and identifies unauthorized wireless signal transmission sources.
[0021] The bottom of the wireless monitoring receiver 1 is equipped with a detachable shielding component 5 to prevent scratches on the bottom of the wireless monitoring receiver 1. Several interfaces are provided on one side of the wireless monitoring receiver 1, and each interface is protected by a protective component 6 to shield and protect the interface. The interfaces are USB interface, HDMI interface, VGA interface, LAN interface, audio interface, MIC interface, GPS positioning expansion port, signal input port, and power interface. The shielding component 5 and the protective component 6 protect the wireless monitoring receiver 1 for safe use in the vicinity of airports and in mountainous areas.
[0022] When using the wireless monitoring receiver 1, select an open location away from obvious obstructions and strong interference sources, securely install the directional antenna onto the housing, connect it to the corresponding antenna interface of the host, and turn on the host power; through the touch screen, set the frequency range to be monitored, and observe the panoramic spectrum scan, discrete scan, or real-time scan data on the screen to monitor radio signals. The shielding component 5 includes a metal plate 51, with screw holes 52 at each of the four corners. The civil aviation wireless monitoring receiver needs to monitor radio signals in complex environments such as the vicinity of airports and mountainous areas. The metal plate 51 prevents gravel and branches on the ground from scratching the bottom of the housing. When the wireless monitoring receiver body 1 is placed on the ground or on the operating table, the metal plate 51 and the corner protectors 2 first contact the ground to prevent sharp objects such as gravel and branches from scratching the bottom of the housing and to extend the service life of the equipment. The metal plate 51 can be made of aluminum alloy.
[0023] A limiting groove 53 is provided at the bottom of the corner guard 2 located at the bottom of the wireless monitoring receiver body 1. The metal plate 51 is adapted to the inner side of the limiting groove 53. The inner side of the screw hole 52 is connected to the corner guard 2 by a bolt. An elastic washer is sleeved on the outside of the bolt to prevent the bolt from loosening. The metal plate 51 is located at the bottom of the wireless monitoring receiver body 1. The metal plate 51 can be removed and replaced by removing the bolt inside the screw hole 52. The distance between the metal plate 51 and the wireless monitoring receiver body 1 is ≥5 mm.
[0024] The protective component 6 includes a transparent cover plate 61 and a locking mechanism. A rotating shaft is fixedly inserted into one side of the transparent cover plate 61, and a connecting frame 63 is rotatably connected to the outside of the rotating shaft. A protrusion 62 is fixed to one side of the connecting frame 63. A sealing ring (not shown in the figure) is adhered to the inner wall of the transparent cover plate 61. The sealing ring can be made of rubber or silicone. The sealing ring is clamped between the transparent cover plate 61 and the wireless monitoring receiver body 1. The locking mechanism includes a connecting rod 67, and a locking block 69 is fixed to one side of the connecting rod 67. A sliding groove 611 is opened on one side of the transparent cover plate 61, and a sliding rod 65 is fixed to the inner wall of the sliding groove 611.
[0025] The wireless monitoring receiver body 1 has an insertion slot 610 on one side of its back. A limit block 68 is fixed to the inner wall of the insertion slot 610. A protrusion 62 is bolted to one side of the wireless monitoring receiver body 1. When the locking block 69 is inserted into the insertion slot 610, the transparent cover 61 is in the closed state. When the locking block 69 leaves the insertion slot 610, the transparent cover 61 is in the open state. When the transparent cover 61 is closed, the locking block 69 is inserted into the insertion slot 610 on the back side of the wireless monitoring receiver body 1 and is locked by the limit block 68, so that the transparent cover 61 is in the closed state. When it is necessary to open the transparent cover 61, the operator pushes the slider 64 upward. The slider 64 drives the connecting rod 67 to slide along the slide rod 65, compressing the spring 66, so that the locking block 69 leaves the insertion slot 610, and the transparent cover 61 can be rotated to open the interface.
[0026] The outer side of the slide rod 65 slides through one side of the connecting rod 67. The connecting rod 67 is fixed with a slider 64 located outside the transparent cover plate 61. A spring 66 is sleeved on the outer side of the slide rod 65. The spring 66 has a certain compression, which gives it a certain elastic potential energy. The two ends of the spring 66 are respectively connected to one side of the connecting rod 67 and the slide groove 611. The spring 66 should be inspected and maintained regularly. When replacing it, the transparent cover plate 61 and other parts need to be replaced as a whole.
[0027] A handle 3 is installed on one side of the wireless monitoring receiver body 1. The position of the handle 3 makes it easy for the operator to carry the wireless monitoring receiver body 1 with one hand. The operator can carry the wireless monitoring receiver body 1 by holding the handle 3, which is convenient for moving between different monitoring locations. Heat dissipation holes 4 are provided on both sides of the wireless monitoring receiver body 1. The heat dissipation holes 4 on both sides of the wireless monitoring receiver body 1 can dissipate the heat generated by the body during operation in time, so as to avoid the equipment performance being affected by high temperature.
[0028] In this embodiment, the wireless monitoring receiver body 1 is a CH103 model manufactured by Qingdao Yizhuo Optoelectronic Technology Co., Ltd. Since the structure and operating principle of this model of wireless monitoring receiver body 1 are existing technologies, their structure and operating principle will not be described in detail here. Furthermore, the specific model of the wireless monitoring receiver body 1 mentioned in this embodiment is for illustrative purposes only and does not represent that this utility model is limited to a particular commercial product. Any wireless monitoring receiver body 1 with a corresponding installation interface can be adapted to this shielding component 5 and protective component 6. In practical applications, adaptive adjustments can be made according to different wireless monitoring receiver bodies 1.
[0029] Working principle: When the operator moves the wireless monitoring receiver body 1 by holding the handle 3, the device enters the dynamic protection state. The corner guards 2 fixed at the four corners of the wireless monitoring receiver body 1 play a role first, which can directly resist the corner bumps that may occur during the carrying process, and prevent the outer shell of the wireless monitoring receiver body 1 from being deformed or damaged due to impact. Since civil aviation wireless monitoring receivers need to monitor radio signals in complex environments such as airport perimeters and mountainous areas, gravel, branches, and other debris on the ground may scratch the bottom of the casing. The metal plate 51 effectively prevents these sharp objects from scratching the bottom of the wireless monitoring receiver body 1, thus providing protection; it also isolates the bottom casing of the wireless monitoring receiver body 1 from gravel, branches, weeds, and other debris on the ground, preventing these objects from directly contacting the casing and thus preventing the casing from being scratched or punctured by sharp objects. Meanwhile, the protective component 6 is in the closed state. The sealing ring bonded to the inner wall of the transparent cover 61 is tightly clamped between the transparent cover 61 and the wireless monitoring receiver body 1, which can seal the gap between the two and prevent external dust and sand from entering the wireless monitoring receiver body 1 through the interface gap during the carrying process, thus protecting the interface and internal circuit from contamination. When the interface on one side of the wireless monitoring receiver body 1 is needed, push the slider 64 located on the outside of the transparent cover 61 upward. The slider 64 drives the connecting rod 67 fixed thereto to slide along the sliding rod 65 in the slide groove 611. At this time, the spring 66 sleeved on the outside of the sliding rod 65 is compressed by the connecting rod 67. The locking block 69 fixed on the other side of the connecting rod 67 moves with the connecting rod 67 and gradually disengages from the limiting block 68 in the insertion groove 610 on the back of the wireless monitoring receiver body 1. When the locking block 69 completely leaves the inside of the insertion groove 610, the locking state of the transparent cover 61 is released. Since one side of the transparent cover plate 61 is rotatably connected to the connecting frame 63 via a pivot, and the connecting frame 63 is bolted to the wireless monitoring receiver body 1 via a protrusion 62, the transparent cover plate 61 can be rotated around the pivot to fully expose the interface, making it convenient for operators to connect cables. After the interface is used, the transparent cover plate 61 is rotated in the opposite direction until the transparent cover plate 61 is in contact with the side wall of the wireless monitoring receiver body 1; the slider 64 is released, the compressed spring 66 releases its elastic force, pushes the connecting rod 67 to reset along the slide rod 65, and the locking block 69 is reinserted into the insertion slot 610 and engaged with the limiting block 68. At this time, the transparent cover plate 61 is in the closed state, the sealing ring seals the gap again, restores the shielding and protection of the interface, and prevents foreign objects from entering. In summary, when the operator carries the wireless monitoring receiver 1 by the handle 3, the corner protectors 2 fixed at the four corners can directly resist possible bumps and knocks during carrying, effectively preventing the outer shell of the wireless monitoring receiver 1 from being deformed or damaged due to impact. For situations where the wireless monitoring receiver 1 needs to work in complex environments, the metal plate 51 prevents the shell from being scratched or punctured by sharp objects at the bottom of the wireless monitoring receiver 1, playing an important protective role.
[0030] When the protective component 6 is in the closed state, the sealing ring adhered to the inner wall of the transparent cover 61 tightly clamps between the transparent cover 61 and the wireless monitoring receiver body 1, sealing the gap between them and preventing external dust and sand from entering the wireless monitoring receiver body 1 through the interface gap during transport, thus protecting the interface and internal circuitry from contamination. When the interface on one side of the wireless monitoring receiver body 1 needs to be used, the operator only needs to push the slider 64 located on the outside of the transparent cover 61 upwards, which will drive the connecting rod 67 to slide along the slide rod 65 in the slide groove 611, causing the locking block 69 to disengage from the limiting block 68 and releasing the locked state of the transparent cover 61. Subsequently, the transparent cover 61 can be rotated around the pivot to fully expose the interface, facilitating cable connection, preventing foreign objects from entering during transport, and ensuring stable equipment performance.

In particular, the features described in the various embodiments and / or claims of this utility model can be combined or combined in various ways without departing from the spirit and teachings of this utility model.
