[0002] Wrist blood pressure monitors are a type of electronic blood pressure monitor. They are multifunctional, fully automatic electronic intelligent blood pressure measuring devices with advantages such as ease of use, safety, small size, and portability. Existing wrist blood pressure monitors typically include an LCD screen and a wristband. When in use, simply wrap the wristband around the wristband and fix it to the person's wrist. The LCD screen and microcomputer control will then quickly and accurately measure the person's blood pressure and pulse rate, helping them to regularly monitor their blood pressure and pulse.
[0003] In the prior art, wristbands of wrist-type electronic blood pressure monitors are generally made of cloth and secured with Velcro on both sides. When in use, because the cloth is relatively soft, it is relatively complicated to wrap the two sides around the wrist. Moreover, after a period of use, the adhesion of the Velcro decreases, posing a risk that the two wristbands may separate when the blood pressure monitor's air bladder inflates during testing, thus affecting the test results. Therefore, we disclose an electronic blood pressure monitor with an adjustable wristband to meet people's needs. Utility Model Content
[0004] The purpose of this application is to provide an electronic blood pressure monitor with an adjustable wristband, in order to solve the problems mentioned in the background art, where the relatively soft cloth band is complicated to wrap around the wrist on both sides, and the Velcro's adhesion weakens after a period of use, posing a risk that the wristbands may separate when the blood pressure monitor's air bladder inflates during testing, thus affecting the test results.

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.
[0027] Example 1
[0028] refer to Figure 1-6 The aforementioned adjustable wristband electronic blood pressure monitor includes an electronic blood pressure monitor body 1, with arc-shaped wristbands 4 rotatably mounted on both sides of the electronic blood pressure monitor body 1. Fixing seats 2 are fixedly mounted on both sides of the electronic blood pressure monitor body 1. Rotating holes are opened on one side of each of the two fixing seats 2, and rotating shafts 3 are rotatably mounted thereon. The two arc-shaped wristbands 4 are respectively fixedly sleeved on the two rotating shafts 3. One end of one arc-shaped wristband 4 is equipped with a T-shaped post 13, and the other end of the arc-shaped wristband 4 is rotatably mounted with a tensioning piece 11 through a rotating post 19. An oblique latch 12 is opened on one side of the tensioning piece 11. The oblique latch 12 matches the T-shaped post 13 and together with the two arc-shaped wristbands 4, forms a closed loop.
[0029] A drive assembly for rotating the arc-shaped wristband 4 is installed on one side of the electronic blood pressure monitor body 1. A central air bladder 6 is installed on the inner side of the closed ring on the electronic blood pressure monitor body 1. A sensor is installed on one side of the central air bladder 6. Side air bladders 7 are installed on the concave sides of the two arc-shaped wristbands 4. The central air bladder 6 and the two side air bladders 7 are connected by a hose 14.
[0030] Based on the above structure, during use, the two arc-shaped wristbands 4 are driven to rotate and move away from each other by the drive component, forming a large opening between the two arc-shaped wristbands 4. At this time, one side of the electronic blood pressure monitor body 1 is brought close to the wrist, the two arc-shaped wristbands 4 rotate and encircle the wrist, and then the tension plate 11 is rotated, and the oblique latch 12 is locked into the T-shaped post 13, so that the electronic blood pressure monitor body 1 is firmly fixed on the wrist. At the same time, the central air bladder 6 and the side air bladder 7 are close to the wrist. During measurement, the central air bladder 6 and the side air bladder 7 are inflated and pressed against the wrist. The sensor is in contact with the wrist and performs blood pressure measurement. Under the traction of the tension plate 11, the two arc-shaped wristbands 4 are firmly locked together. By setting multiple oblique latches, it can be adapted to wrists of different thicknesses, increasing the applicability range.
[0031] like Figure 1 and 4 As shown, the drive assembly includes a first gear 8, which is rotatably mounted on the middle of one side of the electronic blood pressure monitor body 1 via a central shaft. The central shaft and two rotating shafts 3 are located on the same plane. A second gear 10 is correspondingly sleeved at one end of each of the two rotating shafts 3. Two push rods 9 are slidably mounted on one side of the electronic blood pressure monitor body 1 via a C-shaped sliding seat 15. The first gear 8 is located in the middle of the two push rods 9. Grooves are provided on the sides of the two push rods 9 that are close to each other, and racks 17 are installed in the grooves. The two racks 17 are connected to the first gear 8. The two racks 17 mesh with the corresponding second gears 10. The racks 17 on the push rods 9 mesh with the first gear 8 and the corresponding second gears 10 at the same time. When one of the push rods 9 slides, the first gear 8 and the corresponding second gear 10 rotate synchronously. When the first gear 8 rotates, it drives the two push rods 9 to move synchronously in opposite directions. When the second gear 10 rotates, it drives the corresponding rotating shaft 3 and the arc-shaped wristband 4 to rotate, so that the two arc-shaped wristbands 4 rotate synchronously and move away from or closer to each other, forming a tightening and loosening of the wrist, which is convenient to use.
[0032] Example 2
[0033] like Figure 4 As shown, a lever 18 is installed at one end of the push rod 9 on the side away from the central airbag 6. The lever 18 facilitates the movement of the push rod 9 and increases the ease of operation.
[0034] like Figure 4 As shown, a first limiting block 16 is installed on the end of the push rod 9 away from the lever 18. One side of the first limiting block 16 matches one side of the corresponding C-shaped sliding seat 15. By setting the first limiting block 16, the push rod 9 can be prevented from slipping off the C-shaped sliding seat 15. This can also prevent the gap between the two arc-shaped wristbands 4 from being too small, which would cause excessive clamping force on the wrist and discomfort.
[0035] like Figure 6As shown, a second limiting block 20 is installed on one end of one of the rotating shafts 3 away from the second gear 10, and a stop block 21 is installed on one side of the corresponding fixed seat 2. One side of the second limiting block 20 matches one side of the stop block 21. By setting the second limiting block 20, the gap between the two arc-shaped wristbands 4 is prevented from being too large, thus avoiding wasted stroke.
[0036] like Figure 6 As shown, the elastic unit includes a torsion spring 5, which is sleeved on the rotating shaft 3. The arc-shaped wristband 4 has a notch to avoid the torsion spring 5. One end of the torsion spring 5 is installed on one side of the arc-shaped wristband 4, and the other end is installed on one side of the electronic blood pressure monitor body 1. Through the setting of the torsion spring 5, the torsion force of the torsion spring 5 can bring the two arc-shaped wristbands 4 closer to each other, forming a certain clamping force, so that the two arc-shaped wristbands 4 can be clamped on the wrist.
[0037] like Figure 5 As shown, the tensioning piece 11 has multiple angled slots 12. By setting multiple angled slots 12, it can adapt to wrists of different thicknesses and increase the range of applications.
[0038] like Figure 2 and Figure 3 As shown, a threaded hole 24 is provided on the inner wall of the upper C-shaped sliding seat 15. A bolt 23 is installed in the threaded hole 24. The size of the bolt 23 can be referenced from the adjustment knob of an existing mechanical watch. Multiple evenly arranged circular grooves 22 are provided on the side of the push rod 9, and the bolt 23 is positioned corresponding to the circular grooves 22. As the two arc-shaped wristbands 4 rotate and move away from each other, the push rod 9 moves. When a large opening is formed between the two arc-shaped wristbands 4, the bolt 23 is positioned corresponding to the circular groove 22. Rotating the bolt 23 moves it into one of the circular grooves 22, thereby limiting its position.
[0039] Working principle of this utility model:
[0040] In use, by pushing the push rod 9, the two arc-shaped wristbands 4 are driven to rotate along the corresponding pivot 3 and move away from each other, forming a large opening between the two arc-shaped wristbands 4. At this time, one side of the electronic blood pressure monitor body 1 is brought close to the wrist. Under the action of the torsion spring 5, the two arc-shaped wristbands 4 rotate along the pivot 3 and encircle the wrist. Then, the tension plate 11 is rotated, and the oblique latch 12 locks into the T-shaped post 13, so that the electronic blood pressure monitor body 1 is firmly fixed on the wrist. At the same time, the central air bladder 6 and the side air bladder 7 are close to the wrist. During measurement, the central air bladder 6 and the side air bladder 7 are inflated and pressed tightly against the wrist. The sensor is in contact with the wrist to measure blood pressure. Under the traction of the tension plate 11, This design ensures that the two curved wristbands 4 are securely fastened, providing a safe and stable fit, and making them easy to use. The two racks 17 mesh with the first gear 8 and the corresponding second gear 10. The racks 17 on the push rod 9 mesh with both the first gear 8 and the corresponding second gear 10. When one of the push rods 9 slides, the first gear 8 and the corresponding second gear 10 rotate synchronously. When the first gear 8 rotates, it drives the two push rods 9 to move synchronously in opposite directions. When the second gear 10 rotates, it drives the corresponding rotating shaft 3 and the curved wristbands 4 to rotate, thereby causing the two curved wristbands 4 to rotate synchronously and move away from or closer to each other, thus tightening and loosening the wristbands.
[0041] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
