[0001] The utility model relates to the technical field of medium wave transmitters, in particular to a medium wave transmitter with a noise reduction structure. Background Art
[0002] A medium wave transmitter is a type of transmitter, which is a device used to send medium wave signals. It is mainly used for signal transmission of radio and television. The medium wave transmitter is mainly composed of a power supply part, a signal processing part, a modulation part, an amplifier and a transmitting part. The medium wave transmitter has the characteristics of simple structure, high transmission quality, wide coverage and stable reception quality.
[0003] In order to transmit signals, when a medium wave transmitter is needed for assistance, the medium wave transmitter is first placed on the base, and then the medium wave transmitter is started to process the signal, and then the signal is modulated to the required medium wave frequency band through the modem, and then the signal is amplified and sent out; but during the use of the medium wave transmitter, as the use time increases, the medium wave transmitter will inevitably malfunction, and at this time it is necessary to inspect the inside of the medium wave transmitter, but when people inspect the medium wave transmitter, they usually open the box door directly, then put their upper body into the inside of the medium wave transmitter, and then use tools for inspection. However, this inspection method causes people's arms to be restricted by the side walls of the medium wave transmitter, which is inconvenient for people to move, and then leads to increased time consumption for the inspection of the medium wave transmitter, thereby affecting the use of the medium wave transmitter. Utility Model Content
[0004] The purpose of the present utility model is to provide a medium wave transmitter with a noise reduction structure to solve the problem that when using the medium wave transmitter proposed in the above background technology, people's arms are restricted by the side walls of the medium wave transmitter, which leads to increased maintenance time of the medium wave transmitter and thus cannot meet people's usage needs.
[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a medium wave transmitter with a noise reduction structure, comprising a base, a medium wave transmitter body and a modem, the medium wave transmitter body being docked with the middle of the top end of the base, and the outer wall of the medium wave transmitter body being connected to a box door via a hinge mechanism, and a mounting plate being docked with the inside of the medium wave transmitter body, the top end of the outer wall of the mounting plate being docked with the modem, and the outer wall of the modem being provided with a fixing mechanism, and the fixing mechanism comprising a support plate, a guide rod A, a guide rod B, a spring A, a fixing plate, a bidirectional screw and a limit plate, and the bottom end of the modem being connected to the support plate.
[0006] Preferably, a guide rod A is connected to one side of the top end of the support plate, and a guide rod B is connected to the other side of the top end of the support plate.
[0007] Preferably, the guide rod B and the outer wall of the guide rod A are sleeved with a spring A.
[0008] Preferably, a bidirectional screw is connected to the top of the fixing plate, and both sides of the outer wall of the bidirectional screw are threadedly connected to limit plates.
[0009] Preferably, a noise reduction mechanism is provided on the outer wall of the base, and the noise reduction mechanism includes a limit seat, a noise reduction box, a threaded column, a guide plate, a turntable, a limit pin and a spring B, and the limit seat is internally connected to the noise reduction box.
[0010] Preferably, threaded columns are threadedly connected on both sides of the interior of the noise reduction box, and the bottom end of the limit seat is connected to the base.
[0011] Preferably, one side of the outer wall of the threaded column is connected to a guide plate through a bearing seat, and the other side of the outer wall of the threaded column is connected to a turntable.
[0012] Preferably, the outer wall of the turntable is connected to a limit pin, and a spring B is sleeved on the outer wall of the limit pin.
[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: when the medium wave transmitter with the noise reduction structure is used, the fixation of the modem is canceled by the fixing mechanism, and the modem is then taken out for maintenance. Therefore, during maintenance, there is no need to worry about the restriction of the medium wave transmitter main body shell on people, which saves time and facilitates maintenance. The medium wave transmitter main body is limited by the noise reduction mechanism, and the noise reduction box is installed on the outside of the medium wave transmitter main body, thereby reducing the interference of noise on the medium wave transmitter during operation, ensuring the integrity and transmission quality of the signal, and thus facilitating the limiting and noise reduction when the medium wave transmitter is in use.
[0014] 1. In order to transmit the signal, in the process of assisting with the medium wave transmitter, first open the box door to move the limit plates away from each other until the limit plates are disconnected from the modem, and then push the fixing plate upward to disconnect the modem, thereby canceling the fixation of the modem. At this time, the modem is taken out from the medium wave transmitter body for inspection. When inspecting the internal components of the medium wave transmitter body, there is no need to worry about the restrictions of the medium wave transmitter body shell on people, saving time, thereby facilitating inspection when the medium wave transmitter is in use;
[0015] 2. In order to transmit the signal, when assisting the medium wave transmitter, first rotate the threaded column to drive the guide plate to fit with the outer wall of the medium wave transmitter body, and then limit the medium wave transmitter body to prevent the medium wave transmitter body from moving at will. When the turntable moves, the limit pin is squeezed to dock with the noise reduction box, and then the noise reduction box is limited, and then the noise reduction box is installed on the outside of the medium wave transmitter body. At this time, the noise reduction box reduces the interference of noise on the medium wave transmitter during operation, and then ensures the integrity and transmission quality of the signal, thereby facilitating the limitation and noise reduction when the medium wave transmitter is used.

[0023] 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.
[0024] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 The utility model provides a technical solution: a medium wave transmitter with a noise reduction structure, comprising a base 1, a medium wave transmitter body 2 and a modem 5, wherein the medium wave transmitter body 2 is docked at the middle of the top of the base 1, and the outer wall of the medium wave transmitter body 2 is connected to a box door 3 through a hinge mechanism, and a mounting plate 4 is docked inside the medium wave transmitter body 2, the top of the outer wall of the mounting plate 4 is docked with the modem 5, and the outer wall of the modem 5 is provided with a fixing mechanism 6, and the fixing mechanism 6 includes a support plate 61, a guide rod A62, a guide rod B63, a spring A64, a fixing plate 65, and a bidirectional screw 6 6 and a limit plate 67, the bottom end of the modem 5 is connected to a support plate 61; a guide rod A62 is docked on one side of the top of the support plate 61, and a guide rod B63 is docked on the other side of the top of the support plate 61; a fixing plate 65 is sleeved on the outer wall of the guide rod B63, and a spring A64 is sleeved on the outer wall of the guide rod A62; a bidirectional screw 66 is connected to the top of the fixing plate 65, and both sides of the outer wall of the bidirectional screw 66 are threadedly connected to the limit plate 67; the guide rod A62 and the guide rod B63 are parallel to each other, and a guide cavity is opened inside the fixing plate 65 to dock with the limit plate 67, and the support plate 61 is fixedly connected to the mounting plate 4.
[0025] In a specific implementation, in order to perform signal transmission, when the medium wave transmitter malfunctions and needs to be repaired as the medium wave transmitter is used for a long time, the door 3 is first opened, and then the bidirectional screw 66 is rotated. Since the bidirectional screw 66 and the limit plate 67 are threadedly connected, the rotation of the bidirectional screw 66 causes the limit plates 67 to move away from each other until the limit plates 67 are disconnected from the modem 5. Then, the fixing plate 65 is manually pushed upward, so that the fixing plate 65 moves upward along the guide rods A62 and B63.
[0026] When the fixing plate 65 moves, it squeezes the spring A64, causing the spring A64 to deform until the fixing plate 65 is disconnected from the modem 5, thereby canceling the fixation of the modem 5. At this time, the modem 5 is taken out of the medium wave transmitter body 2 for maintenance. When the internal components of the medium wave transmitter body 2 are then inspected, there is no need to worry about the limitations of the shell of the medium wave transmitter body 2, thereby saving time and facilitating maintenance when the medium wave transmitter is in use.
[0027] When the medium wave transmitter is overhauled, the modem 5 is first placed on the support plate 61. Then, the spring A64 is reset to start the fixing plate 65 to move downward. At this time, the guide rod B63 guides the movement of the fixing plate 65 until the fixing plate 65 fits against the outer wall of the modem 5. Then, the bidirectional screw 66 is rotated to drive the limit plate 67 to move in the direction of approaching each other until the limit plate 67 fits against the outer wall of the modem 5, thereby fixing the modem 5. Components of different sizes can be fixed in the above manner, so that the components that have been overhauled can be installed.
[0028] See Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that the outer wall of the base 1 is provided with a noise reduction mechanism 7, and the noise reduction mechanism 7 includes a limit seat 71, a noise reduction box 72, a threaded column 73, a guide plate 74, a turntable 75, a limit pin 76 and a spring B77. The limit seat 71 is internally connected to the noise reduction box 72; the threaded columns 73 are threadedly connected on both sides of the noise reduction box 72, and the bottom end of the limit seat 71 is connected to the base 1; one side of the outer wall of the threaded column 73 is connected to the guide plate 74 through the bearing seat, and the threaded column 73 is connected to the guide plate 74 through the bearing seat. A turntable 75 is docked on the other side of the outer wall; the outer wall of the turntable 75 is connected to a limit pin 76, and the outer wall of the limit pin 76 is sleeved with a spring B77; a limit groove is provided at the top of the base 1 to dock with the limit pin 76, and a limit hole is provided at the bottom of the noise reduction box 72 to dock with the limit pin 76. An elastic telescopic mechanism is formed between the limit pin 76, the limit seat 71 and the spring B77. The noise reduction box 72 is made of a sound insulation board, and the bottom end of the limit seat 71 is welded to the base 1.
[0029] During specific implementation, in order to transmit signals, in the process of assisting the medium wave transmitter, in order to prevent noise from interfering with the integrity and transmission quality of the signal, when noise reduction processing is required, since the limit seat 71 is connected to the base 1, the bottom end of the noise reduction box 72 is first connected to the limit seat 71, and since the threaded column 73 is threadedly connected to the noise reduction box 72, then the turntable 75 is rotated to drive the threaded column 73 to rotate. Since the threaded column 73 is connected to the guide plate 74, the movement of the threaded column 73 drives the guide plate 74 to move together until the guide plate 74 is in contact with the outer wall of the medium wave transmitter body 2, thereby limiting the medium wave transmitter body 2 to prevent the medium wave transmitter body 2 from moving at will;
[0030] Because the outer wall of the turntable 75 is connected to the limit pin 76, the turntable 75 presses the limit pin 76 when it moves, so that the turntable 75 moves in the direction close to the medium wave transmitter body 2, and the limit pin 76 presses the spring B77 when it moves, so that the spring B77 is deformed, and then the spring B77 is reset to assist the limit pin 76 to return to its position until the limit pin 76 docks with the noise reduction box 72, thereby limiting the noise reduction box 72.
[0031] Then, the noise reduction box 72 is installed on the outside of the medium wave transmitter body 2. Since the noise reduction box 72 is made of a sound insulation board, the noise interference on the medium wave transmitter during operation is reduced by the noise reduction box 72, thereby ensuring the integrity and transmission quality of the signal, thereby facilitating position limiting and noise reduction when the medium wave transmitter is in use.
[0032] To sum up, when using the medium wave transmitter with a noise reduction structure, the medium wave transmitter body 2 is first placed on the base 1, and then the medium wave transmitter body 2 is started to process the signal, and then the signal is modulated to the required medium wave frequency band through the modem 5 on the mounting plate 4, and then the signal is amplified and sent out. This is the existing technology and will not be elaborated on here. The fixation of the modem 5 is cancelled by the fixing mechanism 6, and then the modem 5 is taken out for maintenance, so that there is no need to worry about the restrictions of the medium wave transmitter body 2 shell on people during maintenance, which saves time. The medium wave transmitter body 2 is limited by the noise reduction mechanism 7 to prevent the medium wave transmitter body 2 from moving at will, and the noise reduction box 72 is installed on the outside of the medium wave transmitter body 2, thereby reducing the interference of noise on the operation of the medium wave transmitter and ensuring the integrity and transmission quality of the signal. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
