Description

Technical Field

[0001] This utility model relates to the field of medical equipment auxiliary devices, and in particular to an indoor high-load suspension structure. 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 operating rooms and ICU wards. Pendant systems have multiple functions, such as suspending medical equipment, providing lighting, and ventilation, thus facilitating medical work. However, with the continuous updating and upgrading of medical equipment, the safety and reliability of pendant systems have become increasingly important.

[0003] The existing technical solutions have the following drawbacks: as demand increases and the functions of crane towers become more and more numerous, the equipment they support is also increasing day by day. Therefore, it is very important to effectively improve the load-bearing capacity of crane towers. Utility Model Content

[0004] The purpose of this invention is to provide an indoor high-load suspension structure 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 indoor high-load suspension structure includes a fixed disc and a crossbeam. The axis of the fixed disc is vertically arranged, and a through-hole is provided at the center of the top of the fixed disc. A tapered roller bearing is fixedly installed on the top of the fixed disc, and the outer ring of the tapered roller bearing is fixedly connected to the fixed disc. A rotating shaft passes through the inner ring of the tapered roller bearing from top to bottom. The bottom end of the rotating shaft passes through the shaft hole and extends to the bottom of the fixed disc. An annular groove is provided at the bottom of the fixed disc. A crossbeam located below the fixed disc is fixedly installed at the bottom of the rotating shaft. The length direction of the crossbeam is left-right. A support rod is fixedly installed at the top right end of the crossbeam, and a roller is provided at the top of the support rod. A slider is slidably installed at the bottom left end of the crossbeam. The slider slides along the length direction of the crossbeam, and a suspension rod is rotatably installed at the bottom of the slider.

[0007] By adopting the above technical solution, multiple devices to be used are fixedly installed on the boom during use. Therefore, the boom will apply a downward pulling force to the left end of the crossbeam. Taking the connection between the crossbeam and the pivot as the fulcrum, the right end of the crossbeam will be subjected to an upward reaction force. This reaction force is the reason why the crossbeam cannot bear too much weight, because the length of the left end of the connection between the crossbeam and the pivot needs to be set significantly longer than the right end. Therefore, the pivot will be twisted and deformed by this pulling force. After balancing the forces on the left and right ends of the crossbeam, the pivot will only be subjected to a downward pulling force in the axial direction. At this time, the load-bearing capacity of the pivot will be relatively increased. The role of the support rod is to restrict the right end of the crossbeam, so that the crossbeam is always in the horizontal direction. The roller set at the top of the support rod is used to change the sliding friction between the top of the support rod and the bottom of the fixed disc into rolling friction when the crossbeam rotates, reducing the difficulty of the crossbeam rotation.

[0008] In a further embodiment, the top of the slider is provided with a left-right through clearance groove, which is used to avoid the bottom end of the crossbeam. The front and rear sides of the bottom end of the crossbeam are both provided with left-right through sliding grooves. The top of the inner end of the clearance groove is provided with a protrusion corresponding to the sliding groove. The middle of the inner bottom of the clearance groove is provided with a vertical through mounting hole. The mounting hole is a stepped circular hole. The inner top diameter of the mounting hole is larger than the inner bottom diameter. A thrust ball bearing is fixedly installed on the inner top stepped surface of the mounting hole. The top end of the hanger rod passes through and enters the clearance groove from bottom to top. The top end face of the hanger rod is in contact with the bottom end face of the crossbeam. The top end of the hanger rod is provided with an annular protrusion. The bottom end face of the annular protrusion is in contact with the top end face of the thrust ball bearing.

[0009] By adopting the above technical solution, the interplay between the annular protrusion and the thrust ball bearing allows the suspension rod to rotate freely axially while the weight is entirely distributed to the upper ring of the thrust ball bearing via the annular protrusion. The upper ring of the thrust ball bearing is fixedly connected to the inner top stepped surface of the clearance groove, thus preventing radial swaying of the suspension rod during rotation and further improving the stability and load-bearing capacity of the suspension structure. Furthermore, the clearance groove and sliding groove allow the slider to slide flexibly on the crossbeam, and the cooperation between the protrusion and the sliding groove ensures the stability of the slider during sliding, preventing it from falling off or wobbling. This design not only improves the safety of the suspension structure but also makes the entire structure more compact and rational, facilitating installation and maintenance. In practical applications, this indoor high-load suspension structure can support more medical equipment, providing greater convenience for medical work.

[0010] In a further embodiment, the top of the boom is provided with a through hole extending vertically, a ring is fixedly installed at the bottom inner end of the through hole, a locking rod is slidably installed vertically inside the through hole, the bottom end of the locking rod is provided with a protrusion located inside the through hole, the bottom end of the locking rod is provided with a threaded surface, the top end of the locking rod is fitted with the bottom end of the crossbeam, and the inner ring of the ring is provided with a thread.

[0011] By adopting the above technical solution, when the locking rod is turned, the upper and lower positions of the locking rod can be adjusted due to the mutual cooperation between the threaded surface and the inner ring thread of the ring. When the top of the locking rod is completely engaged with the bottom of the crossbeam, the slider is restricted from moving. When there is a gap between the top of the locking rod and the bottom of the crossbeam, the slider can slide.

[0012] In a further embodiment, the top of the roller is located within the annular groove.

[0013] By adopting the above technical solution, the movement path of the roller is restricted by the annular groove.

[0014] In a further embodiment, a sealing ring is installed in the annular groove, and the sealing ring has a notch at the position corresponding to the top of the roller. The sealing ring can rotate freely axially, and the bottom end face of the sealing ring is coplanar with the bottom end face of the ring fixing disc.

[0015] By adopting the above technical solution, the visual difference caused by the complete exposure of the annular groove can be avoided.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. By setting the connection between the crossbeam and the pivot as the fulcrum, the right end of the crossbeam will be subjected to an upward reaction force. This reaction force is the reason why the crossbeam cannot bear too much weight. Because the length of the left end of the connection between the crossbeam and the pivot needs to be significantly longer than that of the right end, the pivot will be twisted and deformed by this tension. After balancing the forces on the left and right ends of the crossbeam, the pivot is only subjected to a downward tension in the axial direction. At this time, the load-bearing capacity of the pivot will increase relatively much. The role of the support rod is to restrict the right end of the crossbeam so that the crossbeam is always in the horizontal direction. The roller set at the top of the support rod is used to change the sliding friction between the top of the support rod and the bottom of the fixed disc into rolling friction when the crossbeam rotates, reducing the difficulty of the crossbeam rotation.
