[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0046] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0047] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0048] The ventilator display uses two different connection methods for vertical and horizontal rotation, and there is no locking mechanism. Another type of display bracket adjusts and fixes vertically and horizontally by tightening and loosening nuts. Both existing bracket technologies rely on friction to fix the medical device when adjusting the pitch angle by tightening nuts. Since the medical device is subjected to gravity in the vertical direction for a long time, relying solely on friction for fixation may loosen, which could lead to changes in the pitch angle or sudden tilting, posing a safety hazard or damaging the medical device.

[0049] In view of this, see Figures 1 to 9 The rotating bracket provided in this embodiment of the utility model includes a bracket connecting rod 100, a locking component 300, a clamping component 400, a fixing plate 500, and two rotating arms 200. The two ends of the bracket connecting rod 100 are respectively rotatably connected to the two rotating arms 200, and the rotation axes of the two rotating arms 200 are set at an angle. At least one rotating arm 200 is connected to the bracket connecting rod 100 with a locking component 300. The clamping component 400 is connected to one rotating arm 200, and the fixing plate 500 is connected to the other rotating arm 200. The clamping component 400 has an adjustable clamping space 410.

[0050] Specifically, in this embodiment, the rotation axes of the two rotating arms 200 are perpendicular. The rotating arm 200 connected to the clamping assembly 400 has its rotation axis vertically set, and this rotating arm 200 rotates relative to the support rod 100 to adjust the horizontal angle of the fixing plate 500. The rotating arm 200 connected to the fixing plate 500 has its rotation axis horizontally set, and this rotating arm 200 rotates relative to the support rod 100 to adjust the vertical angle of the fixing plate 500. Furthermore, in this embodiment, a locking assembly 300 is installed between the rotating arm 200 connected to the fixing plate 500 and the support rod 100 to control the vertical adjustment of the fixing plate 500, thereby controlling the tilt angle and locking the display or other device at a specific tilt angle to prevent dangerous situations caused by sudden tilting of the display or other device. It is worth noting that because a locking component 300 needs to be installed on the rotating arm 200 used to control the pitch angle and the support rod 100, the rotation axis of the rotating arm 200 with the locking component 300 installed should be set to horizontal when using the rotating support.

[0051] Both rotating arms 200 are rotatably connected to the support rod 100, and their rotation axes are set at an angle, allowing the two rotating arms 200 to rotate relative to the support rod 100 in different directions. The two rotating arms 200 are respectively connected to a fixing plate 500 and a clamping assembly 400. The fixing plate 500 is used to mount medical devices such as monitors that require adjustment of pitch and horizontal angles. The clamping assembly 400 is mounted on a fixing rod or frame. Because the two rotating arms 200 can rotate relative to the support rod 100 around different rotation axes, the fixing plate 500 can be adjusted relative to the clamping assembly 400 in four directions, thereby allowing the monitor to be adjusted relative to the fixed mechanism in four directions. At least one rotating arm 200 is fitted with a locking assembly 300 between itself and the support rod 100. After adjustment, at least one rotating arm 200 can be locked using the locking assembly 300 to prevent wobbling or other problems. The clamping assembly 400 has an adjustable clamping space 410, allowing it to be adapted to different sizes and specifications of fixing frames / fixing rods and other fixing mechanisms in medical settings, thus increasing the applicability of the rotating support. Furthermore, this rotating support has few accessories, a small size, and is easy to use.

[0052] The structure of the rotating support is described in detail below:

[0053] In an optional embodiment of this utility model, the locking component 300 includes a locking button 310, an elastic element 320, and a plurality of locking holes 330. The plurality of locking holes 330 are disposed on the rotating support arm 200 on which the locking component 300 is mounted. The middle part of the locking button 310 is rotatably connected to the support rod 100, and the rotation axis is perpendicular to the rotation axis of the rotating support arm 200 on which the locking component 300 is mounted. One end of the elastic element 320 is connected to one end of the locking button 310, and the other end is connected to the support rod 100. The end of the locking button 310 away from the elastic element 320 is provided with a locking protrusion 311, and the locking protrusion 311 engages with any of the locking holes 330.

[0054] Specifically, multiple locking holes 330 are provided on the side wall of the rotating arm 200 and are spaced apart along the rotation direction of the rotating arm 200. Furthermore, the multiple locking holes 330 can be locked at a commonly used pitch angle, for example, adjustable between -15° and 15°, with each 10° increment. After the pitch angle is adjusted to the correct position, the locking protrusion 311 on the locking button 310 engages with the corresponding locking hole 330 to achieve locking. Preferably, the elastic element 320 is a spring, and the locking button 310 has a first mounting groove, while the bracket connecting rod 100 has a second mounting groove 140. The two ends of the spring are respectively installed in the first mounting groove and the second mounting groove 140, improving the installation stability of the spring.

[0055] The elastic element 320 and the locking hole 330 are located at both ends of the locking button 310, and the middle part of the locking button 310 is rotatably connected to the bracket connecting rod 100. The locking button 310 is similar to a seesaw structure. When the rotating support arm 200 needs to be adjusted, the user presses the end of the locking button 310 where the elastic element 320 is installed, so that the locking protrusion 311 is separated from the locking hole 330, and the elastic element 320 is compressed. When the rotating support arm 200 is adjusted to the appropriate position, the user releases the force on the locking button 310, the elastic element 320 returns to its original shape, and drives the locking protrusion 311 to be inserted into the corresponding locking hole 330.

[0056] In an optional embodiment of this utility model, the locking button 310 has an arc-shaped protrusion 312 in the middle, and the arc-shaped protrusion 312 is rotatably connected to the bracket connecting rod 100.

[0057] Specifically, the outer wall of the arc-shaped protrusion 312 has an arc-shaped cross-section, allowing the locking button 310 to make a smooth, rounded contact with the bracket connecting rod 100, thus preventing the locking button 310 from failing to lift. Furthermore, the arc-shaped protrusion 312 has a first rotating hole, the axis of which is set along the rotation axis of the locking button 310. A rotating shaft 340 is fitted inside the first rotating hole, and both ends of the rotating shaft 340 are connected to the bracket connecting rod 100, thereby achieving a rotatable connection between the locking button 310 and the bracket connecting rod 100.

[0058] The arc-shaped protrusion 312 makes the locking button 310 and the bracket connecting rod 100 make a smooth transition contact, avoiding the problem that the locking button 310 cannot be lifted or gets stuck when lifted.

[0059] In an optional embodiment of this utility model, the bracket connecting rod 100 is provided with two oppositely arranged support protrusions 110, and the locking button 310 is located between the two support protrusions 110 and is rotatably connected to the two support protrusions 110.

[0060] Specifically, both support protrusions 110 are provided with second rotating holes 111, and the two ends of the rotating shaft 340 are respectively inserted into the second rotating holes 111 and are interference-fitted with the second rotating holes 111.

[0061] The locking button 310 is located between the two support protrusions 110, enabling the locking button 310 to be rotatably connected to the bracket connecting rod 100.

[0062] In an optional embodiment of this utility model, each rotating arm 200 is provided with a through hole 210, and both ends of the support connecting rod 100 are provided with two opposite mounting holes 120; the rotating shaft 600 passes through the through hole 210, and both ends are respectively connected to the two mounting holes 120.

[0063] Specifically, the rotation axes 600 of the two rotating arms 200 are set vertically.

[0064] The two ends of the rotating shaft 600 are respectively connected to two mounting holes 120 and pass through the through hole 210 to realize the rotational connection between the rotating arm 200 and the bracket connecting rod 100. Of course, the scheme in which the bracket connecting rod 100 has a through hole 210 and the rotating arm 200 has two opposing mounting holes 120 should also be within the protection scope of this utility model embodiment.

[0065] In an optional embodiment of this utility model, a damping ring 700 is fitted between the rotating shaft 600 and the rotating support arm 200.

[0066] Specifically, the damping ring 700 is sleeved on the rotating shaft 600, and the rotating arm 200 is sleeved on the outside of the damping ring 700. There is a certain clamping force between the rotating arm 200, the damping ring 700, and the rotating shaft 600. The inner and outer surfaces of the damping ring 700 have a certain roughness. Under the action of the clamping force, a certain frictional force is generated between the outer surface of the damping ring 700 and the rotating arm 200, and between the inner surface of the damping ring 700 and the rotating shaft 600, so that the rotating arm 200 will not swing arbitrarily when rotating in the left-right and up-down directions.

[0067] The damping ring 700 increases the damping between the rotating shaft 600 and the rotating arm 200, preventing the rotating arm 200 from swinging arbitrarily.

[0068] In an optional embodiment of this utility model, the rotating support arm 200 includes a support arm body 220 and a first adjusting member 230; the two ends of the support arm body 220 are bent to form through holes 210, and the first adjusting member 230 passes through one end of the support arm body 220 and is adjustablely connected to the other end.

[0069] Specifically, the first adjusting element 230 is a bolt that passes through one end of the support arm body 220 and is threaded to the other end. The clamping force between the rotating support arm 200, the damping ring 700 and the rotating shaft 600 is adjusted by tightening or loosening the bolt.

[0070] The first adjusting member 230 enables adjustment of the clamping force between the rotating arm 200, the damping ring 700, and the rotating shaft 600.

[0071] In an optional embodiment of this utility model, one end of the support rod 100 is provided with a limiting groove 130, and one of the rotating arms 200 is provided with a limiting head 240, which extends into the limiting groove 130.

[0072] Specifically, the rotating arm 200 with the locking component 300 is provided with a limiting head 240, and one end of the corresponding bracket connecting rod 100 is provided with a limiting groove 130.

[0073] A limiting groove 130 is provided on the support rod 100, and a limiting head 240 is provided on the rotating arm 200 in the vertical direction. The limiting head 240 extends into the limiting groove 130. During normal pitch angle adjustment, the limiting head 240 has room to move in the limiting groove 130 and will not interfere with each other. If the locking component 300 is not locked properly and the medical device tilts down, the limiting groove 130 and the limiting head 240 can prevent the medical device from tilting down too much and hitting medical staff or other equipment.

[0074] In an optional embodiment of this utility model, the clamping assembly 400 includes a second adjusting member 420 and a clamping block 430 having a clamping space 410; one end of the second adjusting member 420 passes through the side wall of the clamping block 430 and extends into the clamping space 410, and is adjustablely connected to the side wall of the clamping block 430 to adjust the volume of the clamping space 410.

[0075] Specifically, the second adjusting member 420 is threadedly connected to the side wall of the clamping block 430.

[0076] The second adjusting member 420 extends into the clamping space 410 to work together with the side wall of the clamping block 430 to clamp the fixing frame or fixing rod and other fixing mechanisms, so as to be able to clamp to fixing mechanisms of different sizes; and if it is necessary to adjust the height of the medical device, it can be adjusted by first loosening the second adjusting member 420, then moving the clamping block 430 to the required height, and finally tightening the second adjusting member 420.

[0077] In the optional embodiments of this utility model, see Figure 9 The fixing plate 500 has multiple mounting holes 510, which allows the rotating bracket to be connected to medical devices such as monitors, and different mounting holes 510 can be adapted to different products.

[0078] The advantages of the rotating bracket are explained in detail below:

[0079] The rotating bracket employs two rotating arms 200, a rotating shaft 600, and a damping ring 700 to achieve rotational adjustment in all directions. The two rotating arms 200 are connected by a bracket connecting rod 100 to form an assembly. The rotating shaft 600 is fixedly connected to the bracket connecting rod 100 by bolts or other means. The damping ring 700 is fitted onto the rotating shaft 600, and the rotating arms 200 are fitted onto the outside of the damping ring 700. By tightening the bolts on the rotating arms 200, a certain clamping force is generated between the rotating arms 200, the damping ring 700, and the rotating shaft 600. The inner and outer surfaces of the damping ring 700 typically have a certain degree of roughness. Under the action of the clamping force, a certain frictional force is generated between the outer surface of the damping ring 700 and the rotating arms 200, and between the inner surface of the damping ring 700 and the rotating shaft 600. This prevents the rotating arms 200 from swinging arbitrarily when rotating in the left-right or up-down directions. A locking hole 330 is added to the rotating support arm 200 for adjusting the pitch angle, and a locking button 310, elastic element 320, and rotating shaft 340 are added to the support rod 100. This allows the medical device to be locked at a certain angle, preventing dangerous situations such as sudden tilting. A limit groove 130 is also provided on the support rod 100, and a limit head 240 is provided on the rotating support arm 200 in the vertical direction. The limit head 240 extends into the limit groove 130. During normal pitch angle adjustment, the limit head 240 has room to move within the limit groove 130 and will not interfere with each other. If the locking mechanism is not properly locked and the medical device tilts downward, the limit groove 130, in conjunction with the limit head 240, can prevent the medical device from tilting down too much and hitting medical staff or other equipment. Existing support devices are large and heavy, making installation and use inconvenient. This rotating support minimizes the size of the support rod 100 while ensuring adjustable functionality, making it easy to use. This can provide more application scenarios for medical equipment.

[0080] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0081] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
