Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a monitor. Background Art

[0002] A monitor is a medical device used to monitor the patient's physiological parameters. It is usually used in hospitals, ambulances and other medical institutions to monitor the patient's vital signs and other important physiological parameters, helping medical staff to understand the patient's health status in a timely manner and take appropriate medical measures.

[0003] Traditional monitors usually use a fixed-angle screen design, which requires users to adjust the height or overall angle of the monitor according to different usage scenarios to obtain a suitable viewing angle. Such a setting is inflexible and difficult to apply to situations with a wide range of application scenarios and inconsistent heights. Since the screen angle of traditional monitors is fixed, it is difficult for users to clearly observe the information on the screen when they lower their heads or look up. For example, when the monitor is placed at a position lower than the horizontal field of view of a standing human body, the user may need to bend over or lower his head, making it difficult to see the screen content at a vertical angle. The design of traditional monitors does not take into account application scenarios at different heights, such as placing them on a trolley or on a wall. Therefore, users need to constantly adjust the angle and height of the monitor when using it to adapt to different observation needs.

[0004] Therefore, a monitor is needed to solve the above problems. Utility Model Content

The middle shell device 200 and the front shell device 100 can rotate forward or backward relative to the rear shell device 300. By setting up the rotating device 400, the middle shell device 200 and the front shell device 100 can be rotated forward or backward relative to the rear shell device 300, that is, the two-way rotation of the monitor screen is realized, and the rotation axis of the rotating device 400 is ensured to be distributed at the lower part, the middle part and the upper part of the side of the rear shell device 300, which can form a variety of rotation forms of the monitor screen, expand the user's observation angle range, and enable the user to conveniently observe monitors placed at different heights and angles such as high, middle and low positions, thereby ensuring that the monitor can be placed at different heights. It is only necessary to adjust the rotation angle of the middle shell device 200 and the front shell device 100 to observe the vital sign parameters in the monitor, thereby improving the ease of use of the monitor.

[0039] Embodiment 2

[0040] The basic structure of the monitor provided in this embodiment is the same as that in the first embodiment, and only some structures are different. This embodiment only describes the structures that are different from the monitor provided in the first embodiment.

[0041] Please refer to Figure 2-Figure 9Specifically, the rotating device 400 in this embodiment includes a rotating mechanism 410 and an auxiliary connecting mechanism 420, the rear shell device 300 includes a rear shell body 310 and a protrusion 320 extending relative to the rear shell body 310 at the lower part of the side of the rear shell body 310, one end of the rotating mechanism 410 is connected to the protrusion 320, and the other end is connected to the middle shell device 200, one end of the auxiliary connecting mechanism 420 is connected to the rear shell body 310, and the other end is connected to the middle shell device 200. The rotation axis in this embodiment is located at the lower part of the side of the rear shell device 300, and a rotation mechanism 410 is set at the protrusion 320 at the lower part of the side of the reception body, so that the middle shell device 200 can rotate at this position. As shown in the figure, the auxiliary line AA is the lower rotation axis. In order to improve the connection stability, an auxiliary connection mechanism 420 is also set between the rear shell body 310 and the middle shell device 200, so that a stable connection can be formed between the middle shell device 200 and the rear shell body 310 during the rotation process, avoiding the connection being disconnected due to the excessive weight of the upper part of the middle shell device 200, thereby improving the overall connection stability of the monitor. In addition, by setting the protrusion 320, the screen rotation angle of the middle shell device 200 and the front shell device 100 can be further improved. Since the protrusion 320 extends outward relative to the rear shell body 310, and the rotating mechanism 410 is located at the protrusion 320, that is, the rotating shaft is located at the protrusion 320, the middle shell device 200 and the front shell device 100 can be closer to the upper part of the rear shell body 310, and the upward viewing angle of the front shell device 100 can be larger. In actual production, the extension distance of the protrusion 320 relative to the rear shell body 310 can be determined according to the observation angle requirements of the monitor, thereby determining the upper viewing angle limit range of the front shell device 100, which is not limited here and is selected according to the process requirements.

[0042] Furthermore, the rotating device 400 in this embodiment also includes a shielding component, one end of the shielding component is connected to the middle shell device 200, and the other end is connected to the rear shell device 300.

The rotation between the middle shell device 200 and the rear shell device 300 is realized by the rotation mechanism 410, which serves as the basis for the rotation of the two. One end of the first bracket 411 is connected to the middle shell device 200, and the other end is fixedly connected to the threaded rod 4132. One end of the second bracket 412 is connected to the protrusion 320, and the other end of the second bracket 412 is rotatably connected to the threaded rod 4132 to ensure the rotational connection between the first bracket 411 and the second bracket 412, so that the middle shell device 200 and the rear shell device 300 are rotatably connected. The torsion spring 4134 is provided to increase the rotational damping between the middle shell device 200 and the rear shell device 300 to ensure that after the rotation, the middle shell device 200 and the rear shell device 300 can maintain the adjusted relative rotation angle.

By providing a torsion spring assembly 413 in the auxiliary connecting mechanism 420, a damped rotation connection between the two connecting rods 423 is realized.
