Detailed Embodiment

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figure 1 , Figure 2 , Figure 3 shown, a very high frequency (VHF) ground-air communication radio that is convenient for maintenance includes a radio body 1. On the left and right sides of the radio body 1, there are symmetrically arranged two upper and lower fixing brackets 3 through bolts. On the opposite sides of the two upper and lower fixing brackets 3, there are sliding grooves 301 opened. On the opposite sides of the two upper and lower fixing brackets 3, there is a sliding bracket 4 slidably connected. At the upper and lower ends of the sliding bracket 4, there are integrally formed sliders 401 that can slide in the sliding grooves 301. Inside the slider 401, there is a ball 402 movably connected to contact the sliding groove 301, so as to realize the front-back sliding of the sliding bracket 4 between the two upper and lower fixing brackets 3. On the side of the lower sliding bracket 4 away from the radio body 1, there is a U-shaped storage rack 5 hinged. The storage rack 5 can rotate to both sides of the radio body 1. Maintenance supplies are placed inside the storage rack 5. On the side of the upper fixing bracket 3 away from the radio body 1, there are two threaded plates 14 welded. Inside the threaded plates 14, there are fixing bolts 15 threadedly connected. On the side of the upper fixing bracket 3 away from the radio body 1, there are two threaded plates 14 opened. There is a protective cover 2 hinged between the left and right sliding brackets 4. The protective cover 2 can rotate to fit the front side of the radio body 1. On the front side of the protective cover 2, there are buttons and sockets corresponding to the buttons inside the radio body 1. Inside the protective cover 2, there are two groups of limiting components symmetrically arranged on the left and right, so that the protective cover 2 always fits the front side of the radio body 1.

[0020] When in use, the protective cover 2 fits against the front side of the radio body 1. At this time, the sliding frame 4 is located on the left and right sides of the radio body 1, and the rear side of the sliding frame 4 fits against the fixed frame 3. The staff can adjust and control the radio body 1 through the socket and buttons on the front side of the protective cover 2 to ensure the normal operation of the radio body 1. When the radio body 1 needs to be repaired, the staff releases the limit of the protective cover 2 by the limit component, turns the fixing bolt 15 to make the fixing bolt 15 disengage from the storage rack 5, and then pulls the sliding frame 4 forward, so that the sliding frame 4 drives the protective cover 2 to move forward, and turns the protective cover 2 downward to expose the front side of the radio body 1, facilitating the staff to repair the radio body 1. After that, the staff can turn the storage rack 5 to the left and right, so that the internal space of the storage rack 5 faces upward, facilitating the staff to take repair supplies and improving the convenience of the staff in repairing the radio body 1. When the staff finishes the repair, the staff turns the storage rack 5 to the vertical state, pushes the sliding frame 4 to move the storage rack 5 to both sides of the radio body 1, then the staff turns the fixing bolt 15 to be threadedly connected in the threaded hole to prevent the storage rack 5 from rotating when not in use, and finally limits the protective cover 2 through the limit component to prevent the sliding frame 4 from sliding.

[0021] In this embodiment, the limit component includes a limit shaft 9 rotatably connected to the front side of the protective cover 2 through a bearing, a limit post 10 welded to one end of the limit shaft 9 close to the radio body 1, a U-shaped plate 11 fixed to the front side of the radio body 1 by bolts, and a knob 8 provided at one end of the limit shaft 9 extending out of the protective cover 2. The limit post 10 is L-shaped, and the limit post 10 can rotate with the limit shaft 9 and be inserted into the U-shaped plate 11. A damping ring is provided between the limit shaft 9 and the protective cover 2. When in use, the staff pushes the sliding frame 4 to move in the fixed frame 3 until the protective cover 2 contacts the front side of the radio body 1, then the staff turns the protective cover 2 upward so that the rear side of the protective cover 2 fits against the front side of the radio body 1, and then turns the knob 8 to drive the limit shaft 9 and the limit post 10 to rotate, so that the front end of the limit post 10 is inserted into the U-shaped plate 11, so that the protective cover 2 always fits against the front side of the radio body 1, protecting the front side of the radio body 1 and ensuring the protection effect of the protective cover 2 on the radio body 1. When the radio body 1 needs to be repaired, the staff can reverse the rotation of the knob 8 to release the limit, and then turn the protective cover 2 downward.

[0022] In this embodiment, two LED lights 12 are symmetrically arranged on the left and right sides of the rear side of the protective cover 2 by bolts. When repairing the radio body 1, the LED lights 12 can provide a lighting effect and illuminate the front side of the radio body 1, facilitating the staff to repair the radio body 1.

[0023] In this embodiment, a handle 6 is fixed to the front side of the sliding frame 4 by bolts. When pulling the sliding frame 4, the staff can pull the handle 6 to pull the sliding frame 4, which improves the convenience of the staff when pulling the sliding frame 4.

[0024] In this embodiment, four fixing bolts 7 are arranged in a rectangular shape on the front side of the sliding frame 4. The rear ends of the fixing bolts 7 pass through the sliding frame 4 and are connected to the fixing frame 3. When the radio body 1 is in normal use, the sliding frame 4 is connected and fixed to the radio body 1 through the fixing bolts 7 to prevent the sliding frame 4 from sliding, ensuring the reliability of the radio body 1 during use.

[0025] In this embodiment, a magnet 13 is arranged on the side of the sliding frame 4 away from the radio body 1. When the storage rack 5 is not in use, the storage rack 5 fits with the magnet 13. Under the action of magnetic force, the storage rack 5 cannot be separated from the sliding frame 4, thereby preventing the maintenance tools in the storage rack 5 from falling out of the storage rack 5.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
