Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, specifically to a manual key for Morse code training. Background Technology

[0002] As a core training tool for radio operators and military communications personnel, the design of Morse code manual keys has long been limited by the pain points of traditional mechanical structures: classic mechanical keys (such as straight keys and paddle keys) are bulky (weighing 300-500g each), have poor portability, and rely on fixed tables for operation, making it difficult to meet the training needs of field or mobile scenarios; while electronic training devices are lightweight, they generally use plastic buttons and digital synthesized sounds, lacking the tactile feedback of real keys (such as contact pressure and rebound force), resulting in distorted operating feel and affecting the formation of muscle memory for transmitting and receiving codes.

[0003] In implementing this application, existing technologies attempt to simulate training via Bluetooth connection to a mobile app, but this has significant drawbacks: strong dependence on electronic devices (requires continuous power supply), weak anti-interference capability (signal delay > 50ms when the electromagnetic environment is complex), and the buzzer's external noise superimposed (up to 70dB) when multiple people are training simultaneously, causing a chaotic training environment. Some integrated headphone solutions require additional audio interface converters, which are complex to wire and prone to poor contact, violating the principle of simplicity in key operation.

[0004] To address this, Morse code training using manual telegraph keys was proposed. Utility Model Content

[0005] The purpose of this invention is to address the significant drawbacks of existing technologies that attempt to simulate training via Bluetooth connection to a mobile app: strong dependence on electronic devices (requiring continuous power supply), weak anti-interference capability (signal delay > 50ms in complex electromagnetic environments), and the problem of noise from the buzzer being amplified (up to 70dB) during simultaneous training by multiple users, resulting in a chaotic training environment. This invention provides a manual key for Morse code training.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A manual Morse code training key includes a base, a training mechanism for manually sending Morse codes is mounted on the upper surface of the base, a reset mechanism for automatically resetting the training mechanism is mounted inside the base, a stroke adjustment mechanism for limiting the rotation position of the training mechanism is mounted inside the training mechanism, and a protective mechanism for shielding and protecting the internal equipment of the training mechanism is mounted on the upper surface of the training mechanism.

[0008] Furthermore, the training mechanism includes two sets of side plates and a circuit board. The circuit board and the side plates are both mounted on the upper surface of the base. Bearings are installed inside the two sets of side plates, and a connecting plate is installed between the two sets of bearings. A conductive post is mounted on the upper surface of the base. The conductive post is located on the rotation path of the connecting plate. The output end of the circuit board and the input end of the conductive post are electrically connected, and the output end of the connecting plate and the input end of the circuit board are electrically connected.

[0009] Furthermore, the reset mechanism includes three bolts and a reset spring, the reset spring being installed inside the base, and the three bolts being rotatably connected inside the connecting plate.

[0010] Furthermore, the stroke adjustment mechanism includes a second bolt, which is mounted on the upper surface of the base, and a first bolt is rotatably connected inside the connecting plate.

[0011] Furthermore, the protective mechanism includes four sets of screw sleeves, all of which are installed on the upper surface of the circuit board, and protective cover plates are installed on the top of the four sets of screw sleeves.

[0012] Furthermore, four sets of anti-slip pads are installed at the bottom of the base.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model replicates a Morse code transmitter through a training mechanism, and the small size of the training mechanism allows the device to be carried around for training, thus improving its practicality. By pushing a set of 3.5mm audio cables into the socket, the trainee can listen to the sound emitted by the buzzer through headphones during training, thereby minimizing the impact of the device's noise on other users' normal training.

[0015] 2. This utility model features a return spring mounted on the lower surface of bolt three. When the operator presses the keycap, causing the connecting plate to rotate downwards, the return spring, under the action of elastic potential energy, pushes the connecting plate to automatically reset. This reduces the workload for the operator when controlling the training mechanism to send Morse code. Furthermore, rotating bolt three causes it to move downwards within the threaded hole two of the connecting plate. This downward movement compresses the length of the return spring, increasing its elastic potential energy and shortening the time required for the subsequent reset mechanism to push the connecting plate back to its original position. Therefore, this improves the practicality of the device. Attached Figure Description

[0025] like Figures 1 to 4 As shown, the Morse code training manual key includes a base 1, a training mechanism 2 for manually transmitting Morse codes mounted on the upper surface of the base 1, a reset mechanism 4 for automatically resetting the training mechanism 2 inside the base 1, a stroke adjustment mechanism 3 for limiting the rotation position of the training mechanism 2 inside the training mechanism 2, and a protective mechanism 5 for shielding the internal equipment of the training mechanism 2 on the upper surface of the training mechanism 2. Specifically, pressing the training mechanism 2 causes it to emit a sound, allowing the trainee to determine whether their Morse code transmission is correct by judging the sound emitted by the training mechanism 2, thus enabling the user to complete the training of transmitting Morse codes. By replicating a Morse code transmitter through the training mechanism 2 and by using the training mechanism 2 in a compact size, the device can be carried around for training, thus improving its practicality.

[0026] like Figures 1 to 4As shown, the training mechanism 2 includes two sets of side plates 201 and a circuit board 209. Both the circuit board 209 and the side plates 201 are mounted on the upper surface of the base 1. Bearings 202 are installed inside each of the two sets of side plates 201. A connecting plate 203 is installed between the two sets of bearings 202. A conductive post 205 is mounted on the upper surface of the base 1, positioned along the rotation path of the connecting plate 203. The output end of the circuit board 209 is electrically connected to the input end of the conductive post 205, and the output end of the connecting plate 203 is electrically connected to the input end of the circuit board 209. A switch 216 and a socket 215 are mounted on the upper surface of the circuit board 209. The battery compartment 210, conductive post three 217, resistor 212, LED light 213, conductive post two 214, and buzzer 218 are included. A button battery 211 is installed inside the battery compartment 210. The output terminal of the battery compartment 210 and the input terminal of the resistor 212 are electrically connected. The upper surface of the base 1 has threaded holes one, two, four, and two sets of threaded holes five. The external thread of conductive post two 214 is connected to the inside of threaded hole one of the base 1, and the external thread of conductive post one 205 is connected to the inside of threaded hole two of the base 1. The bottom ends of conductive post two 214 and conductive post one 205 are electrically connected through wire harness one 221. The upper part of the connecting plate 203... The surface of the connecting plate 203 has a threaded hole 1. A conductive post 224 is internally threaded into the threaded hole 1 of the connecting plate 203. The external thread of the conductive post 224 is connected to the internal thread of the threaded hole 4 of the base 1. The outer ends of the conductive post 224 and the conductive post 217 are electrically connected via a wire harness 223. The output end of the conductive post 217 is electrically connected to the input end of the buzzer 218 and the LED light 213. The switch 216 is electrically connected to the control end of the battery compartment 210. The upper surface of the connecting plate 203 has a threaded hole 4. The external thread of the screw 207 is connected to the internal thread of the threaded hole 4 of the connecting plate 203. The external thread of the screw 207... The connection is connected to a contact 206, the upper surface of which abuts against the lower surface of the connecting plate 203. The conductive post 205 is located directly below the contact 206. The internal threads of the two sets of threaded holes 5 of the base 1 are connected to screws 3 222. The external threads of screws 3 222 are connected to the base plate 220. The base plate 220 has a threaded hole inside, and screws 219 are connected to the internal threads of the base plate 220. The side plate 201 has threaded holes on both the left and right sides. The external threads of screws 219 are connected to the threaded holes of the side plate 201. Decorative plates 204 are installed on the upper surfaces of the two sets of side plates 201. Keycaps 208 are installed on the upper surface of the connecting plate 203.

[0027] Specifically, by pushing switch 216 to turn it on, the current inside the battery compartment 210 is output to the conductive post 214 via resistor 212. Then, by pressing keycap 208, the connecting plate 203 rotates between the two side plates 201, causing the lower surface of contact 206 to abut against the upper surface of conductive post 205, thus forming an electrical connection between conductive post 205 and conductive post 224. Conductive post 224 then transmits current to conductive post 217 via wire harness 223, and an electrical connection is formed between conductive post 217 and the control terminals of LED light 213 and buzzer 218, causing LED light 213 to emit light and buzzer 218 to emit sound. The user can then determine whether their Morse code transmission is correct by judging the sound emitted by buzzer 218, thereby enabling the user to complete the training of Morse code transmission.

[0028] Meanwhile, by replicating the Morse code transmitter through the training mechanism 2, and by making the training mechanism 2 compact, the device can be carried around for training, thus improving the device's practicality. By pushing a set of 3.5mm audio cables into the socket 215, the trainee can use headphones to listen to the sound emitted by the buzzer 218 during training, thereby minimizing the impact of the device's noise on other users' normal training.

[0029] like Figure 1 and Figure 2 As shown, the reset mechanism 4 includes a bolt 401 and a reset spring 403. The reset spring 403 is installed inside the base 1. The bolt 401 is rotatably connected to the inside of the connecting plate 203. The lower surface of the bolt 401 abuts against the upper surface of the reset spring 403. A groove is provided on the upper surface of the base 1. The reset spring 403 is installed inside the groove of the base 1. A nut 402 is threadedly connected to the outside of the bolt 401. A threaded hole is provided on the upper surface of the connecting plate 203. The outside of the bolt 401 is threadedly connected to the inside of the threaded hole 402 of the connecting plate 203.

[0030] Specifically, by mounting the top of the return spring 403 on the lower surface of bolt 401, the return spring 403 automatically resets itself under the action of elastic potential energy after the operator presses the keycap 208 to rotate the connecting plate 203 downwards. This reduces the workload of the operator when controlling the training mechanism 2 to send Morse code. By rotating bolt 401, bolt 401 moves downwards inside the threaded hole 2 of the connecting plate 203. During the downward movement of bolt 401, the lower surface of bolt 401 compresses the length of the return spring 403, thereby increasing the elastic potential energy of the return spring 403. This shortens the time required for the subsequent reset mechanism 4 to push the connecting plate 203 to reset, thus improving the practicality of the device.

[0031] like Figure 1 and Figure 3 As shown, the stroke adjustment mechanism 3 includes bolt 2 303, which is installed on the upper surface of the base 1. Bolt 1 301 is rotatably connected inside the connecting plate 203. The lower surface of bolt 1 301 abuts against the upper surface of bolt 2 303. A threaded hole 3 is opened on the upper surface of the base 1. Bolt 2 303 is rotatably connected inside the threaded hole 3 of the base 1. A threaded hole 3 is opened on the upper surface of the connecting plate 203. Bolt 1 301 is externally threaded into the threaded hole 3 of the connecting plate 203. Nut 1 302 is externally threaded into bolt 1 301. The lower surface of nut 1 302 abuts against the upper surface of the connecting plate 203.

[0032] Specifically, by positioning bolt 301 below nut 302, bolts 301 and 303 restrict the downward rotation of connecting plate 203, thereby minimizing excessive rotation of connecting plate 203 under the elastic potential energy of reset mechanism 4, which could damage reset spring 403 and thus improve the service life of reset mechanism 4. By rotating nut 302, the nut 302 rotates inside the threaded hole 3 of connecting plate 203, adjusting the distance between the bottom of nut 302 and the upper surface of bolt 301, allowing the stroke adjustment mechanism 3 to adjust the reset distance of connecting plate 203 during use.

[0033] like Figures 1 to 4As shown, the protective mechanism 5 includes four sets of screw sleeves 501, all of which are mounted on the upper surface of the circuit board 209. A protective cover plate 502 is mounted on the top of each of the four sets of screw sleeves 501. Four through holes are formed on the upper surface of the protective cover plate 502. Screws 503 are inserted into the four through holes of the protective cover plate 502, with their external threads passing through the internal through holes of the protective cover plate 502 and installed inside the threaded holes of the screw sleeves 501. Specifically, by pushing the protective cover plate 502, the position of the four sets of through holes of the protective cover plate 502 is adjusted and moved to the four... The upper end of the threaded sleeve 501 is then connected to the inside of the threaded sleeve 501 by rotating the four sets of screws 503 through the four through holes of the protective cover plate 502. This allows the protective cover plate 502 to be positioned and installed on the upper end of the circuit board 209. As a result, the protective mechanism 5 shields and protects the circuit board 209 and the equipment on the upper end of the circuit board 209, thereby minimizing the risk of damage to the circuit board 209 and the equipment on the upper end of the circuit board 209 during use, and thus improving the service life of the circuit board 209 and the equipment on the upper end of the circuit board 209.

[0034] like Figure 4 As shown, four sets of anti-slip pads 6 are installed at the bottom of the base 1. Specifically, by installing four sets of anti-slip pads 6 on the lower surface of the base 1, the friction between the bottom of the base 1 and the placement platform is increased through the four sets of anti-slip pads 6, thereby minimizing the slippage of the base 1 during use and thus improving the stability of the device during use.

[0035] In summary: By pushing switch 216 to open it, the current inside the battery compartment 210 is output to conductive post 214 via resistor 212. Then, by pressing keycap 208, the connecting plate 203 rotates between the two side plates 201, causing the lower surface of contact 206 to abut against the upper surface of conductive post 205, thus forming an electrical connection between conductive post 205 and conductive post 224. Conductive post 224 then transmits current to conductive post 217 via wiring harness 223, and the current flows through conductive post 217, LED light 213, and buzzer. Electrical connection is established between the control terminals of device 218, causing LED light 213 to emit light and buzzer 218 to emit sound. This allows the user to determine whether their Morse code transmission is correct by judging the sound emitted by buzzer 218, thus enabling the user to complete the training of Morse code transmission. The top of the return spring 403 is installed on the lower surface of bolt 3 401. When the operator presses the keycap 208, it causes the rear side of the connecting plate 203 to rotate downwards. Under the action of elastic potential energy, the return spring 403 pushes the connecting plate 203 to automatically reset.

[0036] Simultaneously, by rotating nut 302, the nut 302 rotates inside the threaded hole 3 of connecting plate 203, adjusting the distance between the bottom end of nut 302 and the upper surface of bolt 301, so that the stroke adjustment mechanism 3 can adjust the reset distance of connecting plate 203 during use; by pushing protective cover 502, the position of the four sets of through holes of protective cover 502 is adjusted and moved to the upper end of the four sets of threaded sleeves 501, and then by rotating the four sets of screws 503, the four sets of screws 503 are passed through the four sets of through holes of protective cover 502 and connected to the inside of the four sets of threaded sleeves 501, so that protective cover 502 is positioned and installed at the upper end of circuit board 209, thereby enabling protective mechanism 5 to shield and protect circuit board 209 and the equipment on the upper end of circuit board 209.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
