Description

Technical Field

[0001] The utility model relates to the technical field of radio receivers, in particular to a split-type radio receiver. Background Art

[0002] A radio receiver, also known as a radio receiver, is an electronic device that can receive radio waves and convert the information they carry into a usable form. The main function of a radio receiver is to receive, capture and convert radio signals. These signals are processed by circuits inside the receiver, such as amplification, frequency conversion and demodulation, and are ultimately converted into audible, visible or further processed information.

[0003] However, the existing radio receiver is usually connected to a cable for signal transmission and amplification when in use. However, when the existing radio is folded up and used, the cable and the interface may move or shake due to external force, which will affect the service life of the cable and the use effect of the radio receiver. Therefore, a split radio receiver is proposed. Utility Model Content

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

[0021] See also Figure 1-4 A split-type radio receiver includes a box body 1, a box cover 2 movably connected to the top of the box body 1, a receiver body 3 is provided on the top of the box body 1, a control panel 4 is fixedly installed on the top of the receiver body 3, a cable interface 5 is provided on the front of the receiver body 3, an adjustment and fixing structure 6 is provided on the outside of the box body 1, and a heat dissipation structure 7 is provided inside the box body 1;

[0022] The adjusting and fixing structure 6 includes a connecting plate 601, a connecting plate 601 is fixedly installed on the top of the box cover 2, a mounting block 602 is movably connected to the outer surface of the connecting plate 601, a spring body 603 is fixedly installed inside the mounting block 602, a hinge block 604 is fixedly installed on the outer surface of the box body 1, a hinge rod 605 is hinged inside the hinge block 604, a device block 606 is fixedly installed on the front of the receiver body 3, a vertical plate 607 is fixedly installed inside the device block 606, a bidirectional threaded tapered rod 608 is rotatably connected to the inside of the vertical plate 607, a bevel gear rod 609 is rotatably connected to the inside of the vertical plate 607, and a splint 610 is threadedly connected to the outer surface of the bidirectional threaded tapered rod 608.

[0023] Furthermore, the heat dissipation structure 7 includes a semiconductor refrigerator 701, the semiconductor refrigerator 701 is fixedly installed on the back of the box body 1, a heat conducting plate 702 is fixedly installed on the top of the box body 1, a heat conducting rod 703 is fixedly installed on the bottom of the heat conducting plate 702, a fan 704 is provided on the outside of the heat conducting rod 703, and a filter 705 is fixedly installed on the top of the box body 1.

[0024] Specifically, such as Figure 2 As shown, the semiconductor refrigerator 701 is turned on to produce cold air inside the box body 1, which is then transferred to the heat conducting plate 702 through the heat conducting rod 703, and then transferred to the receiver body 3 through the heat conducting plate 702, so as to dissipate heat and cool the receiver body 3. At the same time, the fan 704 is turned on to extract a step of cold air, and discharge it from the interior of the box body 1 through the filter 705, so as to cool the temperature around the receiver body 3, thereby assisting in dissipating heat and cooling it.

[0025] Specifically, such as Figure 2 As shown, the semiconductor refrigerator 701 consists of a cooling plate, a heat sink and a DC power supply. All of them are devices that use the thermoelectric effect of semiconductors to generate cooling. The cooling plate is mostly an insulating ceramic plate with a first metal conductor provided at the bottom of the ceramic plate. The heat sink contains an insulating ceramic plate inside, with a second metal conductor provided on the ceramic plate. The two metal conductors are connected by N-type and P-type semiconductor bismuth telluride. When the DC power supply is energized, the Peltier effect in the semiconductor produces heat absorption and heat dissipation, thereby producing cold air.

[0026] Specifically, such as Figure 1As shown, after the cable is connected to the cable interface 5 and the cable is fixed by adjusting the fixing structure 6, the receiver body 3 will receive the radio signal and convert it into a weak current signal. The high-frequency amplifier inside the receiver body 3 selects the signal of the required frequency from the many received signals and amplifies it. The received signal and the local oscillation signal are then frequency-converted by the internal frequency converter to output a fixed-frequency intermediate frequency signal. This process realizes the frequency conversion and channel selection of the signal. The intermediate frequency amplifier inside the receiver body 3 then further amplifies the intermediate frequency signal output by the frequency converter to improve the signal-to-noise ratio and level of the signal. The audio signal is then extracted from the amplified intermediate frequency signal through the detector to complete the signal demodulation process. Finally, the demodulated audio signal is amplified by the low-frequency amplifier, and the sound-generating equipment such as the speaker is driven to output the sound, which is then displayed on the control panel 4.

[0027] During implementation, follow these steps:

[0028] 1) Pull the pull rod to move the plug rod out of the plug hole in the connecting plate 601, retract the mounting block 602 and squeeze the spring body 603;

[0029] 2) The cover 2 is then opened via the hinge block 604 and the hinge rod 605 to expose the internal receiver body 3 and connect the cable to the cable interface 5;

[0030] 3) Rotating the bevel gear rod 609 drives the bidirectional threaded tapered rod 608 to rotate, thereby causing the clamping plates 610 on the outer surface of the bidirectional threaded tapered rod 608 to move and clamp each other;

[0031] 4) Finally, the heat dissipation structure 7 is used to dissipate heat and cool the receiver body 3 .

[0032] To sum up, for this split-type radio receiver, the pull rod is pulled to move the plug rod out of the plug hole, and the spring body 603 is squeezed in the mounting block 602, and the two box covers 2 are opened through the hinge block 604 and the hinge rod 605 to expose the internal receiver body 3, and then the cable is connected to the receiver body 3 through the cable interface 5, and then the bevel gear rod 609 is rotated to drive the bidirectional threaded conical rod 608 to rotate, so that the splints 610 on the outer surface of the bidirectional threaded conical rod 608 move relative to each other, thereby fixing the cable, repeating the above operation to remove the cable, and closing the box cover 2 to protect it, thereby achieving the purpose of storing and protecting the equipment and facilitating the fixing of the cable.
