Description

Technical Field

[0001] This utility model relates to the field of industrial control technology, and in particular to an adjustable display screen cantilever. Background Technology

[0002] Medical pendant systems are essential gas supply devices in modern hospital operating rooms. They are primarily used for the terminal transfer of medical gases such as oxygen, suction, compressed air, and nitrogen in operating rooms, and are typically installed in medical environments such as hospital operating rooms and ICU wards. Pendant systems have multiple functions, such as suspending medical equipment, providing lighting, and ventilation, thus facilitating medical work. One particularly important function is the suspension of display equipment to show the microscopic conditions inside the patient's body.

[0003] The aforementioned existing technical solutions have the following drawbacks: In the existing technology, the display screen is generally directly installed on the hanging column. When the position of the display screen needs to be adjusted, the entire hanging column needs to be moved, which is inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable display screen cantilever to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An adjustable display screen cantilever includes a medical pendant tower and a robotic arm. One end of the robotic arm is fixedly connected to the pendant tower, and the other end of the robotic arm is fixedly mounted with a display screen. The robotic arm includes a first rotating shaft, a crossbeam, a second rotating shaft, a connecting rod, and a mounting frame. The first rotating shaft is vertically arranged, and its bottom end is fixedly mounted on the top of the pendant tower. One end of the crossbeam has a receiving groove at its bottom, and a first bearing is fixedly mounted in the receiving groove. The first bearing is sleeved on the top of the first rotating shaft. The second rotating shaft is horizontally arranged, and its bottom end is fixedly mounted on the end of the crossbeam away from the first rotating shaft. The end of the crossbeam away from the first pendant tower has a vertically penetrating mounting groove, and the second rotating shaft is located in the mounting groove. A second bearing is sleeved in the middle section of the second rotating shaft. One end of the connecting rod is sleeved on the second bearing, and the other end of the connecting rod is fixedly connected to the mounting frame. The second rotating shaft has a shaft hole, and a locking device is fixedly mounted in the shaft hole. The locking device is used to fix the rotation angle of the connecting rod.

[0007] By adopting the above technical solution, the first rotating shaft is not equipped with a locking structure during use, allowing the crossbeam to rotate freely around the axis of the first rotating shaft. The connecting rod is used to adjust the height of the display screen, and the mounting bracket is used to adjust the angle of the display screen. When the height needs to be adjusted, the locking device releases the second bearing, allowing the connecting rod to rotate. After the adjustment is completed, the locking device locks the second bearing, preventing the connecting rod from rotating.

[0008] In a further embodiment, a rubber pad is fixedly installed on the top of the first rotating shaft, and the top of the rubber pad is in contact with the inner top of the receiving groove.

[0009] By adopting the above technical solution, the friction between the top surface of the rubber pad and the receiving groove provides a certain resistance when the crossbeam rotates, thus preventing random shaking and allowing the crossbeam to rotate.

[0010] In a further embodiment, the locking device includes a linear drive motor, a gear, and a gear ring. Two second bearings are provided, symmetrically arranged at both ends of the second rotating shaft, and both bearings are located within mounting grooves. The end of the connecting rod connected to the second bearing has a circular hole penetrating both ends. The gear ring is fixedly installed in the middle position inside the circular hole, and the gear ring is coaxial with the circular hole. An annular groove is provided in the middle section of the second rotating shaft, connecting the external and internal spaces of the second rotating shaft. The linear drive motor is fixedly installed in the shaft hole. The gear is fixedly installed on the moving part of the linear drive motor, which moves the gear along the axial direction of the shaft hole. The inner wall of the gear ring is a tooth surface, and the gear ring meshes with the gear.

[0011] By adopting the above technical solution, when the connecting rod needs to rotate, the linear drive motor drives the gear to disengage from the gear ring. The gear ring is unrestrained, so the connecting rod can rotate freely. When it rotates to the position, the linear drive motor pushes the gear into the position coaxial with the ring groove, realizing the meshing of the gear and the gear ring. Because the gear is fixedly installed on the moving part of the linear drive motor, the gear cannot rotate, so the connecting rod cannot rotate.

[0012] In a further embodiment, the end of the gear away from the moving part of the linear drive motor is provided with an acute-angled blunt structure, the gear is a spur gear, and each tooth on the side of the gear with the acute-angled blunt structure is set as an arc shape.

[0013] By adopting the above technical solution, each tooth of the gear is taken out individually and set as one end closer to the moving part and one end farther away from the moving part. The end face of the tooth farther away from the moving part is set as an arc surface. Since the rotation of the connecting rod is random, it is impossible for it to move to the meshing position exactly. At this time, the arc surface is needed to guide the meshing between the teeth. In this way, when the gear is inserted into the gear ring and meshes with it, although it will rotate slightly to the meshing position, this small change can be adjusted back by the mounting bracket at the end, so as to realize the height position adjustment of the connecting rod relative to the display screen.

[0014] In a further embodiment, the mounting bracket includes a mounting plate and an adjustment assembly. The mounting plate is used to mount the display screen, and the adjustment assembly is used to adjust the angle of the mounting plate. The adjustment assembly is configured as a hinge structure, with one end of the hinge structure fixedly mounted on the end of the connecting rod away from the second bearing, and the other end of the hinge structure fixedly connected to the mounting plate.

[0015] The hinge structure allows for adjustment of the angle of the mounting plate relative to the connecting rod, thereby adjusting the angle of the display screen.

[0016] In a further embodiment, to increase the stability and firmness of the display installation, the mounting plate is provided with a plurality of mounting holes for bolting to the mounting bracket on the back of the display.

[0017] In this way, the display screen can be fixed to the mounting plate with bolts, avoiding the display screen from shaking or falling off during use. The indoor high-load suspension structure of this utility model not only solves the problem of inconvenient adjustment of the display screen position in the prior art, but also improves the stability and firmness of the display screen installation, making the display screen more flexible and convenient to install on medical pendant towers, providing more convenience for medical work.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. During use, the first rotating shaft is not equipped with a locking structure, allowing the crossbeam to rotate freely around the axis of the first rotating shaft. The connecting rod is used to adjust the height of the display screen, and the mounting bracket is used to adjust the angle of the display screen. When the height needs to be adjusted, the locking device releases the second bearing, allowing the connecting rod to rotate. After the adjustment is completed, the locking device locks the second bearing, preventing the connecting rod from rotating. Attached Figure Description
