Description

Technical Field

[0001] This utility model relates to the field of heart rate belt technology, and in particular to a heart rate belt that is easy to disassemble. Background Technology

[0002] A heart rate monitor is a device that monitors heart rate. It typically consists of a sensor and a transmitter. The principle of a heart rate chest belt is to measure the periodic changes in cardiac current or potential in the skin through electrodes on both sides of the belt. It can be used to monitor the user's exercise intensity and heart rate, making it easy to understand the changes in heart rate during exercise, thereby adjusting the exercise rhythm and intensity, and avoiding situations such as over-exercising causing injury or under-exercising failing to achieve the desired training effect.

[0003] For example, patent number CN218684377U discloses a heart rate belt with a detachable sensor structure, including a first connecting strap and a second connecting strap. A connecting mechanism is provided on one side of the first and second connecting straps, and a loading plate is fixedly connected between the other side of the first and second connecting straps. The sensor body is installed inside the loading plate through a disassembly mechanism, which includes symmetrical pressing plates. This utility model relates to the field of heart rate belt technology. This heart rate belt with a detachable sensor structure, by providing a disassembly mechanism, utilizes a rotating pressing assembly to cause the pressing plate and pressing rod to move back under the elasticity of a return spring until the pressing rod disengages from the slider's slot, thereby realizing the disassembly operation of the sensor body. This facilitates the disassembly and assembly of the sensor body and effectively avoids the waste caused by replacing the entire sensor body after damage. However, the heart rate belt in this patent requires rotating the connecting part to a suitable position to fasten and loosen during wearing and disassembly, which is inconvenient and affects the efficiency of wearing and doffing.

[0004] Therefore, to address the inconvenience of wearing and removing the aforementioned heart rate belts, which affects the efficiency of donning and doffing, a heart rate belt that is easy to remove can be designed. By combining the connecting structure and adjustment structure with the monitoring structure, the heart rate belt can be easily put on, taken off, and adjusted. Utility Model Content
