Description

Technical Field

[0001] This utility model relates to the field of electronic blood pressure monitor technology, and in particular to a rotating shaft structure for an electronic blood pressure monitor. Background Technology

[0002] An electronic blood pressure monitor is a modern medical device used to non-invasively measure blood pressure and heart rate. Based on advanced sensing and electronic information technologies, it can accurately and quickly provide patients with blood pressure readings, making it an indispensable health monitoring tool in homes and medical institutions.

[0003] The working principle of an electronic blood pressure monitor typically involves key components such as a pressure sensor, a microprocessor, and a display unit. When the cuff is tightly wrapped around the patient's upper arm and inflated to a certain extent, the pressure sensor begins to monitor pressure changes within the cuff. As the gas in the cuff is slowly released, the sensor can capture the moment when arterial blood flow is interrupted and then resumes, known as a "Korotkoff sound" or "oscillatory wave." These signals are then processed by the microprocessor and converted into specific blood pressure values ​​(including systolic and diastolic pressure) and heart rate information.

[0004] The folding blood pressure monitor requires a hinge to connect the main unit to the sleeve. The existing connection structure has poor stability, affecting the accuracy of blood pressure measurements. Therefore, a new design is needed for the existing hinge structure of the blood pressure monitor. Utility Model Content

[0005] To solve the above problems, this utility model achieves multiple technical effects such as stable support, smooth movement, precise control, and high flexibility and stability in the rotating shaft structure of electronic blood pressure monitors.

[0006] The technical solution adopted by this utility model is: a rotating shaft structure for an electronic blood pressure monitor, including a base, a rotating shaft assembly, and a movable assembly. A hinge groove is provided on one side of the base, and hinge mounting platforms are provided on both sides of the hinge groove. The rotating shaft assembly includes a fixed hinge, a movable hinge, and a damping rotating shaft. The fixed hinge and the movable hinge are connected by the damping rotating shaft, and the fixed hinge is mounted on the hinge mounting platform. The movable assembly includes a movable outer shell and a movable connecting seat. The movable outer shell is provided with a rotating shaft connecting platform, and one end of the movable connecting seat is connected to the movable hinge, and the other end is connected to the rotating shaft connecting platform.

[0007] A further improvement to the above solution is that the upper surface of the base is provided with a mating plane, and the movable outer shell is provided with an abutting plane, the abutting plane being used to abut against the mating plane.

[0008] A further improvement to the above solution is that a mating groove is provided on one side of the mating plane, and a mating buckle is provided on one side of the abutting plane, the mating buckle being used to fasten onto the mating groove.

[0009] A further improvement to the above solution is that the hinge groove is used to mate with the movable connecting seat, and the movable connecting seat moves along the hinge groove via a rotating shaft assembly.

[0010] A further improvement to the above solution is that the fixed hinge is provided with a fixed connecting part, one end of which is connected to the base.

[0011] A further improvement to the above scheme is that the damping shaft includes a rotating shaft and damping springs, and multiple damping springs are provided. A locking nut is provided at one end of the damping shaft to lock the damping springs. The movable hinge is provided on the rotating shaft.

[0012] A further improvement to the above solution is that the movable outer shell is provided with a detection cavity, which is used to install the cloth cover.

[0013] A further improvement to the above solution is that the movable connecting seat is provided with a hinge platform, which is used to install the movable hinge; the hinge platform is provided with mounting holes and positioning pins.

[0014] A further improvement to the above solution is that a connecting post is provided between the movable connecting seat and the movable housing, and a screw is provided inside the connecting post for connecting the movable connecting seat and the movable housing to each other.

[0015] A further improvement to the above solution is that movable limiting platforms are provided on both sides of the movable connecting seat. The movable limiting platforms are used to cooperate with the hinged mounting platform to limit the rotation of the movable connecting seat.

[0016] The beneficial effects of this utility model are:

The movable assembly 3 includes a movable outer shell 31 and a movable connecting seat 32. The movable outer shell 31 has a rotating shaft connecting platform 33. One end of the movable connecting seat 32 is connected to the movable hinge 22, and the other end is connected to the rotating shaft connecting platform 33. This embodiment, through the ingenious arrangement of the hinge groove 11 and the hinge mounting platform 12 on the base 1, provides a stable yet flexible support foundation for the rotating shaft assembly 2. This design not only ensures the stability of the electronic blood pressure monitor during unfolding and folding, but also effectively avoids loosening or deformation caused by long-term use, thereby extending the product's lifespan. Secondly, the cooperation of the fixed hinge 21, movable hinge 22, and damping shaft 23 in the rotating assembly 2 achieves precise control and cushioning of the movable component 3. The application of the damping shaft 23 allows the movable housing 31 to maintain a uniform and smooth movement when opening and closing, avoiding impacts and noise caused by sudden acceleration or deceleration, thus improving the user experience. At the same time, this design effectively prevents damage to the movable component 3 caused by excessive rotation, further enhancing the product's reliability. Furthermore, the connection between the movable housing 31 and the movable connecting seat 32 in the movable assembly 3 and the movable hinge 22 via the rotating connecting platform 33 achieves high flexibility and stability. This connection method not only allows the movable housing 31 to be easily flipped and positioned as needed, but also ensures that it remains firmly fixed in any usage state, avoiding the impact of shaking or external interference on the accuracy of measurement results. This embodiment achieves multiple technical effects, including stable support, smooth movement, precise control, and high flexibility and stability.

[0028] The upper surface of the base 1 is provided with a mating plane 13, and the movable housing 31 is provided with an abutting plane 311, which abuts against the mating plane 13. Specifically, one side of the mating plane 13 is provided with a mating groove 131, and one side of the abutting plane 311 is provided with a mating buckle 312, which is used to fasten onto the mating groove 131. In this embodiment, the precise alignment of the mating plane 13 and the abutting plane 311 effectively enhances the stability of the electronic blood pressure monitor structure. This design ensures that the movable housing 31 remains tightly fitted to the base 1 during rotation or fixation, avoiding measurement errors caused by loosening or misalignment.
