Description

Technical Field

[0001] This utility model relates to the field of heart rate belt technology, specifically to a heart rate detection device that is easy to adjust. Background Technology

[0002] Heart rate monitors are currently the most accurate wearable devices for measuring heart rate on the market. They simulate the electrocardiogram (ECG) used in hospitals and work on the principle of measuring cardiac current. They can convert nerve signals into rhythmic electrical signals, which can be monitored and recorded by electrode instruments after they are diffused to the body surface.

[0003] Existing heart rate monitors are typically worn around the chest of the upper body, with the sensor aligned with the heart for detection. Most existing heart rate monitors are secured using elastic bandages, which constantly exert pressure on the body, potentially causing skin irritation, marks, and discomfort. Furthermore, existing heart rate monitors have a limited range of adjustment; the greater the deformation, the greater the stress on the body, making them difficult to adjust to individual needs. Those that use buckles and straps for adjustment are cumbersome and prone to loosening, and their closed-loop design makes them difficult to remove from the body. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model provides an easily adjustable heart rate detection device, including a heart rate detector 1, with a strap 2 fixedly connected to the top of the heart rate detector 1, and a limiting mechanism 3 provided at the end of the strap 2, which allows for more convenient adjustment of the length of the strap 2.

[0027] The limiting mechanism 3 includes a fixing block 31. The outer wall of the fixing block 31 is fixedly connected to the end of the strap 2. The inner wall of the fixing block 31 has a corresponding slot for the strap 2 to pass through. An adjusting threaded rod 37 is threadedly connected to the inner wall of the top of the fixing block 31. A knob 32 is fixedly connected to the top of the adjusting threaded rod 37 for manual rotation. By rotating the threaded rod 37, it can move vertically along the fixing block 31. A disc 38 is fixedly connected to the bottom of the threaded rod 37. Two sets of arc-shaped grooves 310 are formed on the inner wall of the disc 38. A slider 312 is slidably connected to the inner wall of the arc-shaped grooves 310. The slider 312 has a circular cross-section and a convex bottom end to prevent it from falling off the arc-shaped grooves 310. A sliding rod 39 is slidably connected through the inner wall of the slider 312. The sliding rod 39 and the slider 312 can slide relative to each other, changing their overall length to accommodate the downward movement of the disc 38. The bottom end of the sliding rod 39... One end of the limiting spring 311 is fixedly connected to the limiting spring 311, and the other end of the limiting spring 311 is fixedly connected to the inner wall of the slider 312. The elasticity of the limiting spring 311 can limit and reset the slider 312. The top end of the sliding rod 39 is horizontally slidably connected to the top inner wall of the fixed block 31. A connecting rod 34 is fixedly connected to the outer wall of the sliding rod 39. A pressing plate 35 is fixedly connected to the outer end of the connecting rod 34. The outer wall of the pressing plate 35 is slidably connected to the inner wall of the fixed block 31. The connecting rod 34 mainly plays a certain connecting role. It can drive the connecting rod 34 and the pressing plate 35 to move synchronously through the sliding rod 39 to press the strap 2. The increased friction from the pressing helps to limit the strap 2. The outer side wall of the pressing plate 35 is fixedly connected to one end of the reset spring 36. The other end of the reset spring 36 is fixedly connected to the inner side wall of the fixed block 31. The elasticity of the reset spring 36 enables the pressing plate 35 to limit and reset.

[0028] A wire clamping mechanism 4 is provided on the outer sidewall of the fixed block 31. The wire clamping mechanism 4 includes a movable block 41. The outer wall of the movable block 41 is slidably connected to the outer wall of the fixed block 31, and the cross-section of the movable block 41 is T-shaped, which matches the inner side of the outer side of the fixed block 31 to prevent it from falling off. A rubber pad is fixedly connected to the inner wall of the fixed block 31 to increase the friction between it and the movable block 41, so that it will not move when not affected by external forces. A semi-circular ring 43 is passed through and fixedly connected to the inner wall of the movable block 41. An annular locking block 44 is slidably connected to the inner wall of the semicircular ring 43. The annular locking block 44 blocks the notch of the semicircular ring 43, which can clamp the connecting wire of the heart rate monitor 1 and play a certain limiting role to prevent the wires from getting tangled. The end of the annular locking block 44 is fixedly connected to one end of the connecting spring 42, and the other end of the connecting spring 42 is fixedly connected to the inner wall of the semicircular ring 43. The elasticity of the connecting spring 42 can keep the annular locking block 44 in a closed loop with the semicircular ring 43 without being affected by external force.

[0029] In this invention, during use, the entire strap 2 is wrapped around the patient's upper body, the heart rate monitor 1 is placed at the patient's heart, and the end of the strap 2 is passed through the slot of the limiting mechanism 3. After adjusting the tightness appropriately, the knob 32 is rotated, causing the threaded rod 37 to rotate. This causes the threaded rod 37 to rotate the disc 38, which in turn causes the arc groove 310 to rotate along the center of the disc 38, pressing against the outer wall of the slider 312. Following the trajectory of the arc groove 310, the slider 312 moves inward, which in turn moves the sliding rod 39 inward, causing the sliding rod 39 to move in a straight line along the inner wall of the fixed block 31 towards the center. The center moves, causing the connecting rod 34 and the extrusion plate 35 to move towards the center, extruding the two sides of the strap 2. At the same time, the threaded rod 37 moves downward when rotating, which can drive the disc 38 to move downward. The disc 38 then drives the slider 312 to move downward. The overall length of the slider 312 and the sliding rod 39 will change. The multiple extrusions of the strap 2 by the extrusion plate 35 and the disc 38 can better limit the strap 2. Then, by moving the annular locking block 44, the annular locking block 44 can slide towards the inner wall of the semi-circular ring 43 and place the connecting wire inside the semi-circular ring 43. Then, the elasticity of the connecting spring 42 drives the annular locking block 44 to reset, tidying up the wire and preventing the wire from becoming messy and tangled.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
