[0002] Modern people attach great importance to healthy living and have a good concept of the need to regularly track their physical health. Cardiovascular disease is one of the most common diseases among Chinese people. In order to detect the disease early and treat it as soon as possible, you can use a sphygmomanometer to measure your blood pressure to get a preliminary understanding of your physical health status.

[0003] There are many types of blood pressure monitors, the most commonly used of which are wrist electronic blood pressure monitors and arm electronic blood pressure monitors, which can be used at home or in the hospital to detect blood pressure values. Currently, wrist electronic blood pressure monitors generally have the blood pressure monitor body fixed on the side wall of the inflatable cuff. However, when measuring blood pressure on patients with existing wrist blood pressure monitors, it is found that the blood pressure monitor cuff becomes dirty and has an odor over time. Since the blood pressure monitor body and cuff of most wrist blood pressure monitors are fixed, the cuff is not easy to clean and disinfect, resulting in a poor patient experience and easy cross-infection. Therefore, a wrist blood pressure monitor is designed to address the above technical defects. Utility Model Content

[0028] In addition, the two limit assemblies 9 are respectively arranged inside the two mounting grooves 10, and the two limit assemblies 9 both include a first clamping block 12 and a second clamping block 13. The first clamping block 12 and the second clamping block 13 are both slidably connected to the inside of the corresponding mounting groove 10, and the side of the first clamping block 12 and the second clamping block 13 close to each other is slidably connected. One end of the first clamping block 12 and one end of the second clamping block 13 are located inside the clamping groove 7, and a plurality of springs 15 are fixedly connected between the other end of the first clamping block 12 and the other end of the second clamping block 13 and the inner wall of the mounting groove 10; when the first clamping block 12 and the second clamping block 13 slide toward the inside of the mounting groove 10, they can squeeze the spring 15. At this time, one end of the first clamping block 12 and one end of the second clamping block 13 enter the mounting groove 10, so that the horizontal end of the L-shaped plate 4 loses its limit, and the L-shaped plate 4 can be pulled out of the clamping groove 7, thereby separating the sphygmomanometer body 1 from the cuff 2.

[0029] In addition, an oblique groove 14 is provided in the middle of the rear side of the first clamping block 12 and the middle of the front side of the second clamping block 13, and a blocking rod 21 is fixedly connected to the middle of the side where the first clamping block 12 and the second clamping block 13 are close to each other, and the two blocking rods 21 are staggered up and down; a limiting groove 20 is provided on the side where the first clamping block 12 and the second clamping block 13 are close to each other, and the two limiting grooves 20 respectively correspond to the corresponding blocking rods 21, and the blocking rods 21 are slidably connected to the inside of the corresponding limiting grooves 20, and the lower surface of one end of the first clamping block 12 and the lower surface of one end of the second clamping block 13 are both slidably connected to the upper surface of the horizontal end of the corresponding L-shaped plate 4; When the first card block 12 moves in the installation groove 10 and compresses the spring 15, the first card block 12 can drive the blocking rod 21 thereon to slide in the limiting groove 20 on the second card block 13, and the second card block 13 does not move; on the contrary, the second card block 13 moves into the installation groove 10 and compresses the spring 15, and the first card block 12 does not move; in this way, when any one of the first card block 12 and the second card block 13 moves, the other does not move, so that the L-shaped plate 4 cannot be unlocked. Only when the first card block 12 and the second card block 13 move into the installation groove 10 at the same time can the L-shaped plate 4 be unlocked.

Only by pressing the pressing blocks 19 at the same time can the L-shaped plate 4 be unlocked.

[0031] Working principle: during use, when the cuff 2 needs to be disassembled for cleaning and disinfection, the pressure blocks 19 on both sides can be pressed at the same time, and the pressure blocks 19 can drive the limit plate 18 to slide into the inside of the slide groove 11. At the same time, the limit plate 18 drives the two push rods 17 thereon to slide into the installation groove 10, so that the four push rods 17 can simultaneously drive the inclined blocks 16 thereon to slide into the corresponding inclined grooves 14. As the inclined blocks 16 move, the inclined surfaces thereon can slide and squeeze with the inclined surfaces of the inclined grooves 14, so that the relative first clamping blocks 12 and the relative second clamping blocks 13 move in the installation groove 10 and squeeze the spring 15, so that the first clamping blocks 12 and the second clamping blocks The block 13 can be separated from the slot 7, so that the L-shaped plate 4 loses its limit; then, pulling the sphygmomanometer body 1 outward can separate the L-shaped plate 4 and the positioning column 3 from the connecting portion 5, so that the cuff 2 can be disassembled for cleaning and disinfection; when pressing the front pressure block 19, the second card block 13 can be moved into the installation slot 10 and compress the spring 15, so that the baffle 21 on the second card block 13 slides in the limit slot 20 on the first card block 12. At this time, the first card block 12 will not move and the L-shaped plate 4 will not be unlocked. Only by pressing the two pressure blocks 19 at the same time can the L-shaped plate 4 be unlocked, which can prevent the sphygmomanometer body 1 from being separated from the cuff 2 by accidentally touching the pressure block 19.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
