DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 In this embodiment, a receiver capable of performing preselection processing comprises a housing 1, a receiver 2 is arranged on the inner bottom wall of the housing 1, an antenna 3 is arranged on the top of the receiver 2, a fixing structure 4 is arranged on the top of the housing 1, and a dustproof structure 5 is arranged inside the housing 1;

[0022] The fixed structure 4 includes a slide plate 401, a slider 1 402, a slide groove 1 403, a hook 404, a movable plate 405, a lifting ring 406, a slider 2 407 and a slide groove 2 408. Two slide plates 401 are arranged on the top of the shell 1. Two sliders 1 402 are fixedly connected to the top of the shell 1. The bottoms of the two slide plates 401 are provided with a slide groove 1 403. The tops of the two slide plates 401 are fixed with hooks 404. The left and right sides of the shell 1 are provided with movable plates 405. The outsides of the two movable plates 405 are hinged with lifting rings 406. The opposite surfaces of the two movable plates 405 are fixedly connected with sliders 2 407. The left and right sides of the shell 1 are provided with slide grooves 2 408.

[0023] The dustproof structure 5 includes a rotating frame 501, a dustproof net 502, a groove 503, a moving block 504, a spring 505 and a moving rod 506. The inner left wall of the outer shell 1 is hinged with the rotating frame 501, the interior of the rotating frame 501 is provided with a dustproof net 502, the right side of the rotating frame 501 is provided with a groove 503, the interior of the groove 503 is provided with a moving block 504, the left side of the moving block 504 is fixedly connected with a spring 505, and the top of the moving block 504 is fixedly connected with a moving rod 506.

[0024] In the case implementation, a slider three can be provided at the bottom of the moving block 504, and a slide groove three can be provided inside the groove 503. The moving block 504 is slidably connected to the rotating frame 501 through the slider three and the slide groove three, so as to fix the moving direction of the moving block 504.

[0025] In the case implementation, when the rotating frame 501 is vertical, it is convenient to clean the dust on the dustproof net 502.

[0026] In the case implementation, after the receiver 2 receives the signal through the antenna 3, it distinguishes whether it is a high-frequency signal or a low-frequency signal, and then transmits it to the digital signal processing module through the corresponding filter, and the signal to be transmitted is transmitted through the amplification filter.

[0027] When implementing, follow these steps:

[0028] 1) When inspecting first, the hook 404 is separated from the lifting ring 406, and the movable plate 405 slides down under the influence of gravity, at which time the two slide plates 401 can be moved toward the separated surfaces;

[0029] 2) Then, the moving rod 506 drives the moving block 504 to move to the left until it is out of the fixing slot, and the rotating frame 501 is rotated to make it vertical, and the dust screen 502 is cleaned;

[0030] 3) After the inspection is completed, the moving rod 506 drives the moving block 504 to move to the left, and the rotating frame 501 is rotated to align the groove 503 with the fixed groove. The moving rod 506 is released, and the elastic force of the spring 505 drives the moving block 504 to enter the fixed groove to prevent dust falling from the gap between the two slide plates 401 from contacting the receiver 2;

[0031] 4) Finally, the two sliding plates 401 are brought into contact with each other, and the two movable plates 405 are moved upward at the same time, and the lifting ring 406 is hung on the hook 404 .

[0032] To sum up, the receiver capable of pre-selection processing separates the hook 404 from the ring 406 by setting a fixed structure 4, and the movable plate 405 slides down under the influence of gravity. At this time, the two slide plates 401 can be moved toward the separated surfaces. After the maintenance is completed, the opposite surfaces of the two slide plates 401 are brought into contact, and the two movable plates 405 are moved up at the same time, and the ring 406 is hung on the hook 404.

[0033] In addition, by providing a dustproof structure 5, the dustproof net 502 prevents falling dust from contacting the receiver 2. During maintenance, the moving rod 506 drives the moving block 504 to move to the left until it is out of the fixed groove, and the rotating frame 501 is rotated to make it vertical, thereby solving the problem of inconvenient disassembly during maintenance in the Chinese utility model patent with patent announcement number CN207067699U, and dust can easily enter, thereby reducing its service life.
