[0001] This utility model relates to the field of receiving device technology, and in particular to frequency conversion receiving device. Background Technology

[0002] In today's field of communication and electronic equipment, frequency conversion receivers are widely used.

[0003] However, existing receivers present numerous maintenance challenges. Traditional receivers are primarily secured with screws, requiring significant time and manpower for disassembly during repairs, making the process cumbersome. Furthermore, prolonged use can lead to stripped or loose screws, increasing disassembly difficulty and potentially damaging components. This can prevent quick repairs, and in severe cases, render the receiver unusable for extended periods, disrupting normal operations.

[0004] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: Since the main body of the receiving device is basically fixed with screws, the operation is cumbersome, the traditional method of maintaining the main body of the receiving device is relatively troublesome, requiring a lot of time and manpower, and long-term use may also lead to stripping of screws and loosening, thus making it impossible for staff to repair quickly, resulting in the problem that the main body of the receiving device cannot be used; therefore, a frequency conversion receiving device is proposed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, which is that the main body of the receiving device is basically fixed with screws, which is cumbersome to operate. The traditional method of maintaining the main body of the receiving device is also troublesome, requiring a lot of time and manpower. Long-term use may also lead to stripping of screws and loosening, which makes it impossible for staff to repair quickly and renders the main body of the receiving device unusable. Therefore, the proposed frequency conversion receiving device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a frequency converter receiving device, comprising a receiving device body, a sliding groove formed on the surface of the receiving device body, a switching device provided on the surface of the receiving device body, the switching device comprising a round rod, the round rod being fixedly connected to the inner wall of the sliding groove of the receiving device body, a rotating block being rotatably connected to the arc surface of the round rod, a control panel being fixedly connected to the surface of the rotating block, a fixing groove formed on the surface of the receiving device body, a shaped block being slidably connected to the inner wall of the fixing groove of the receiving device body, the surface of the shaped block being fixedly connected to the control panel, a sliding rod being slidably inserted into the surface of the receiving device body, an elliptical block being fixedly connected to one end of the sliding rod, and a slot being formed on the surface of the shaped block.

[0007] The effect achieved by the above-mentioned components is as follows: By setting up a switch device, it is convenient for staff to repair the main body of the receiver. During repair, since the main body of the receiver is basically fixed with screws, the operation is cumbersome. The traditional method of repairing the main body of the receiver is relatively troublesome, requiring a lot of time and manpower. Long-term use may also lead to stripping of screws or loosening, which makes it impossible for staff to repair quickly, resulting in the main body of the receiver becoming unusable. This improves the practicality of the device.

[0008] Preferably, a torsion spring is fitted onto the arc surface of the round rod, and the two ends of the torsion spring are fixedly connected to the sliding groove of the receiving device body and the rotating block, respectively.

[0009] The effect achieved by the above components is that, through the cooperation of the main slide groove of the torsion spring receiving device and the rotating block, the control panel can be kept open due to the torsion force of the torsion spring itself when the control panel is opened, which facilitates maintenance or replacement.

[0010] Preferably, a spring is fitted onto the arc surface of the slide rod, and the two ends of the spring are fixedly connected to the elliptical block and the main body of the receiving device, respectively.

[0011] The effect achieved by the above components is that, through the cooperation of the spring elliptical block and the main body of the receiving device, the slide bar can quickly return to its original position when the elliptical block is released due to the elastic force of the spring itself.

Detailed Implementation

[0031] Reference Figure 1 As shown, this utility model provides a technical solution: a frequency converter receiving device, including a receiving device body 1. A groove is formed on the surface of the receiving device body 1, and a switch device 2 is provided on the surface of the receiving device body 1. By setting the switch device 2, it is convenient for staff to maintain the receiving device body 1. During maintenance, since the receiving device body 1 is basically fixed with screws, the operation is cumbersome. Traditional maintenance methods for the receiving device body 1 are relatively troublesome, requiring a lot of time and manpower. Prolonged use may also lead to stripping or loosening, making it difficult for staff to quickly repair, resulting in the receiving device body 1 becoming unusable. This improves the practicality of the device. A protective device 3 is formed on the surface of the receiving device body 1. By setting the protective device 3, when the receiving device body 1 is not in use, it prevents dust, fibers, and other foreign objects from entering the charging port through a sealing method. If these small particles enter the charging port, they may accumulate inside, potentially causing short circuits in key components such as circuit boards and sensors, or preventing the receiving device body 1 from charging, affecting normal operation.

[0032] The specific setup and function of its switching device 2 and protective device 3 will be described in detail below.

[0033] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in this embodiment: the switching device 2 includes a round rod 21, which is fixedly connected to the inner wall of the slide groove of the receiving device body 1. A rotating block 22 is rotatably connected to the arc surface of the round rod 21. A control panel 23 is fixedly connected to the surface of the rotating block 22. A fixing groove is formed on the surface of the receiving device body 1. A shaped block 24 is slidably connected to the inner wall of the fixing groove of the receiving device body 1. The surface of the shaped block 24 is fixedly connected to the control panel 23. A sliding rod 25 is slidably inserted into the surface of the receiving device body 1. An elliptical block 26 is fixedly connected to one end of the sliding rod 25. A slot is formed on the surface of the shaped block 24. A torsion spring 27 is sleeved on the arc surface of the round rod 21. The two ends of the torsion spring 27 are fixedly connected to the slide groove of the receiving device body 1 and the rotating block 22, respectively. A spring 28 is sleeved on the arc surface of the sliding rod 25. The two ends of the spring 28 are fixedly connected to the elliptical block 26 and the receiving device body 1, respectively. A rubber pad 29 is fixedly connected to the surface of the control panel 23. The size of the sliding rod 25 is adapted to the size of the slot of the shaped block 24. The cooperation between the torsion spring 27 and the receiving device body 1's slide groove and the rotating block 22 allows the control panel 23 to remain open when it is turned on, thanks to the torsion of the torsion spring 27 itself, facilitating maintenance or replacement. The cooperation between the spring 28 and the elliptical block 26 and the receiving device body 1 allows the slide rod 25 to quickly return to its original position when the elliptical block 26 is released, due to the elasticity of the spring 28. The cooperation between the rubber pad 29 and the control panel 23 prevents water from entering the receiving device body 1 and causing a short circuit.

[0034] Reference Figure 5 and Figure 6 As shown, specifically, the protective device 3 includes a power inlet 31, which is located on the surface of the receiver body 1. A rotating rod 32 is fixedly connected to the inner wall of the power inlet 31, and a cover plate 33 is rotatably connected to the arc surface of the rotating rod 32. A hook and loop fastener 34 is fixedly connected to the surface of the cover plate 33, and a hook and loop fastener flat surface 35 is attached to the surface of the hook and loop fastener 34. The hook and loop fastener flat surface 35 is fixedly connected to the inner wall of the power inlet 31. Two upright blocks 36 are fixedly connected to the surface of the cover plate 33, and a flat plate 37 is fixedly connected to the surface of the upright blocks 36. Through the cooperation of the hook and loop fastener 34 and the hook and loop fastener flat surface 35, the cover plate 33 can be attached to the power inlet 31 when not in use, preventing the cover plate 33 from being opened when not in use. Through the cooperation of the upright blocks 36 and the flat plate 37 of the cover plate 33, it is convenient for operators to open the cover plate 33.

[0035] Working principle: When the user needs to repair the receiver body 1, the user pulls the elliptical block 26, causing the spring 28 to open. The elliptical block 26 moves the sliding rod 25 away from the irregular block 24. Due to the torque of the torsion spring 27, the torsion spring 27 drives the rotating block 22 to rotate. The rotating block 22 drives the control panel 23 to rotate. The control panel 23 drives the irregular block 24 away from the fixing groove of the receiver body 1. The staff performs the repair. After the repair is completed, the control panel 23 is pressed to drive the irregular block 24 into the fixing groove of the receiver body 1. The elliptical block 26 is released. The elastic force of the spring 28 drives the elliptical block 26 to move. The elliptical block 26 drives the sliding rod 25 to insert into the slot of the irregular block 24, thus completing the installation.

[0036] When the staff needs to open the cover 33 for use, the staff pulls the flat plate 37, the flat plate 37 drives the upright block 36, the upright block 36 drives the cover 33 to rotate, the cover 33 causes the hook and loop fastener surface 34 to not stick to the hook and loop fastener surface 35, the cover 33 rotates on the arc surface of the rotating rod 32, the cover 33 moves away from the plug hole 31, so that the staff can insert the charging head into the receiver body 1, thereby completing the charging and use.
