This utility model discloses a cardiovascular monitoring watchband, relating to the field of cardiovascular monitoring technology. It includes a monitoring body with an insertion port on one side and a watchband on the other. Inside the monitoring body is a rotating shaft with gears outside. Inside the monitoring body is an air bladder with a first air chamber and a second air chamber at its bottom. When worn, the watchband is wrapped around the wrist and inserted into the insertion port. Rotating a knob drives the gears to tighten the watchband, achieving initial fixation. During tightening, the air bladder is compressed, triggering a pressure change in the air chambers. The compressed air chamber transfers gas to the second air chamber, causing the outer air bladder to inflate and press tightly against the wrist skin. This ensures no gap between the monitoring module and the pulse contact surface, solving the technical problem of traditional devices causing discomfort due to excessive tightness or affecting monitoring accuracy due to excessive looseness. It is suitable for long-term health monitoring scenarios.

This utility model proposes a dual shock absorption and stabilization control component for electric bicycles, including an upper connector and a main sleeve. The bottom end of the upper connector is fixedly connected to the main sleeve, and the bottom of the main sleeve is fixedly connected to a sleeve. An adjusting plate is threadedly connected to the outer surface of the main sleeve, and a spring is fixedly connected to the bottom of the adjusting plate. The advantages of this utility model are: improved safety through a safety structure design. A buffer is fixedly connected to the top of the safety device. During shock absorption, the piston moves upward inside the sleeve, compressing the spring. Simultaneously, the nitrogen gas inside the sleeve, channel, and external air cylinder is compressed, causing the safety device and buffer to move upward. The buffer abuts against the bottom end of the sleeve. The wave-shaped structure on the side of the buffer generates multi-directional deformation upon impact, dispersing over 90% of the axial stress, effectively damping and buffering the impact force, effectively preventing excessive nitrogen compression, and preventing the sleeve and external air cylinder from bursting, making it more secure and safer.
