Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a sheet-type damping suspension device for a medical display hanger. Background Art

[0002] In a DSA operating room, a medical display is an essential auxiliary tool for surgical medical staff. The medical display is installed on a medical display hanger. During the operation, medical staff often rotate the medical display hanger in order to obtain the best viewing angle with the screen, and it needs to be stably fixed at a certain position. In traditional suspension devices for medical display hangers, there is no damping mechanism or a cylindrical damper is used. The suspension device without a damping mechanism is very flexible, making it difficult to position the medical display hanger, and even causing a "drift" phenomenon; when using a cylindrical damper, due to its structural characteristics, the friction contact area is small, resulting in serious wear and the damper will quickly fail, with a short service life and frequent maintenance required. The present invention aims to solve the problem that the medical display screen is not easy to position or drifts by itself due to the short service life and failure of the damping mechanism of the medical display hanger. Summary of the Invention

[0003] The purpose of the present invention is to provide a sheet-type damping suspension device for a medical display hanger, which solves the problems existing in the prior art, enables the medical display hanger to operate flexibly for a long time, and at the same time can be stably fixed at a certain position, without frequent maintenance, reducing the maintenance cost.

One end of the hanging shaft is equipped with a bearing and a bearing locking nut, the bearing gland is installed on the bearing of the hanging shaft, the bearing gland is connected to the display hanger assembly, the sheet-type damping component is installed on the damping seat, the damping seat is connected to the hanging shaft, the buffer screw is installed on the limit seat, the limit seat is connected to the bearing gland, and the limit block is connected to the damping seat.

[0005] According to the above technical solution, the beneficial effects that the sheet-type damping suspension device for a medical display hanger of the present invention can achieve are as follows: Compared with the prior art, it enables the medical display hanger to operate flexibly for a long time, and at the same time can be stably fixed at a certain position, without frequent maintenance, reducing the maintenance cost.

[0006] Specifically, the present invention adopts a sheet-type damping suspension device for a medical display hanger. When the screen of the medical display needs to be moved, the medical display hanger can drive it to rotate, and has a certain damping force, so that the display screen can stop arbitrarily at a certain position without "drifting". The pressing sheet-type damping structure greatly increases the service life of the damping mechanism and reduces the maintenance cost.

[0007] Preferably, 2-4 threaded holes are evenly distributed on the upper end surface of the damping seat, and there is a groove on the lower end surface of the damping seat corresponding to each threaded hole, and the groove communicates with the threaded hole.

[0008] According to the above technical solution, the beneficial effects that the sheet-type damping suspension device for a medical display hanger of the present invention can achieve are as follows: 2-4 pressing sheet-type damping components can be installed on the damping seat, so that the damping force is evenly distributed on multiple damping pressing sheets, reducing the wear of the damping pressing sheets, thereby increasing the service life.

[0009] Preferably, the pressing sheet-type damping component includes a damping screw, a damping pressing sheet, and a disc spring. The damping screw is installed in the screw hole on the upper end surface of the damping seat, the damping pressing sheet is installed in the groove on the lower end surface of the damping seat, and several disc springs are installed between the damping screw and the damping pressing sheet.

[0010] According to the above technical solution, the beneficial effects that the sheet-type damping suspension device for a medical display hanger of the present invention can achieve are as follows: The damping screw applies pressure to the damping pressing sheet through several disc springs that are stacked in a positive and negative manner, so that the damping pressing sheet generates frictional damping when rubbing against the bearing gland, and the disc spring can compensate for the pressure after the damping pressing sheet is worn.

[0011] Preferably, the damping seat and the bearing gland can rotate relative to each other through a bearing assembled at one end of the hanging shaft.

[0012] According to the above technical solution, the beneficial effects that the sheet-type damping suspension device for a medical display hanger of the present invention can achieve are as follows: The pressing sheet-type damping component is installed on the damping seat, and the relative rotation between the damping seat and the bearing gland realizes the frictional movement of the pressing sheet-type damping component on the upper end surface of the bearing gland.

[0013] Preferably, there is a gap less than 0.5 mm between the lower end surface of the damping seat and the upper end surface of the bearing gland, and the damping pressing sheet is attached to the upper end surface of the bearing gland.

[0014] According to the above technical solution, the beneficial effects that the sheet-type damping suspension device for a medical display hanger of the present invention can achieve are as follows: When the damping seat and the bearing gland rotate relative to each other, there is no contact friction, and only the damping pressing sheet contacts and rubs against the upper end surface of the bearing. A certain gap facilitates the discharge of abrasive debris.

[0015] Preferably, the damping screw applies pressure to the damping pressing plate through the plurality of disc springs, so that frictional damping is generated by the friction between the damping pressing plate and the bearing gland, and the disc springs can compensate for the pressure after the damping pressing plate is worn.

[0016] According to the above technical solution, the beneficial effects that the chip-type damping suspension device for a medical display hanger of the present invention can achieve are as follows: when the thickness of the damping pressing plate is worn, the plurality of disc springs stacked in a positive and negative buckled manner can still apply a certain pressure to the damping pressing plate without adjusting the damping screw, reducing the maintenance frequency and lowering the maintenance cost.

One end of the 10 hanging shaft is assembled with a bearing and a bearing locking nut. The 30 bearing cap is installed on the bearing of the 10 hanging shaft. The 30 bearing cap is connected to the 40 display hanger assembly. The 80 sheet-type damping component is installed on the 20 damping seat. The 20 damping seat is connected to the 10 hanging shaft. The 60 buffer screw is installed on the 50 limit seat. The 50 limit seat is connected to the 30 bearing cap. The 70 limit block is connected to the 20 damping seat.

[0021] Figure 3 , Figure 4 As shown, the perspective view and assembly view of the sheet-type damping component of the preferred embodiment of the present invention.

[0022] Figure 3 , Figure 4 According to the preferred embodiment of the present invention, the sheet-type damping component includes: 81 damping screws, 82 damping sheets, and 83 disc springs. The 81 damping screws are installed in the threaded holes on the upper end face of the damping seat. The 82 damping sheets are installed in the grooves on the lower end face of the 20 damping seat. The several 83 disc springs are installed between the 81 damping screws and the 82 damping sheets.

[0023] Figure 5 As shown, the perspective view of the damping seat of the preferred embodiment of the present invention.

[0024] Figure 5 As shown in the perspective view of the damping seat of the preferred embodiment of the present invention, 2-4 threaded holes are evenly distributed on the upper end face of the 20 damping seat. There is a groove on the lower end face of the 20 damping seat corresponding to each threaded hole, and the groove communicates with the threaded hole.

[0025] The 20 damping seat and the 30 bearing cap can rotate relative to each other through the bearing assembled at one end of the 10 hanging shaft. The 80 sheet-type damping component is installed on the 20 damping seat. The relative rotation between the 20 damping seat and the 30 bearing cap realizes the frictional movement of the 80 sheet-type damping component on the upper end face of the 30 bearing cap.

[0026] A gap less than 0.5 mm is left between the lower end face of the 20 damping seat and the upper end face of the 30 bearing cap. The 82 damping sheet is in contact with the upper end face of the 30 bearing cap. When the 20 damping seat and the 30 bearing cap rotate relative to each other, there is no contact friction. Only the 82 damping sheet and the upper end face of the bearing have contact friction. A certain gap is convenient for the discharge of grinding debris.

[0027] The 81 damping screw applies pressure to the 82 damping piece through the plurality of 83 disc springs, so that the 82 damping piece generates frictional damping by rubbing against the 30 bearing gland. The 83 disc springs can compensate for the pressure after the 82 damping piece is worn. When the thickness of the 82 damping piece is worn, the plurality of 83 disc springs stacked in a positive and negative buckled manner can still apply a certain pressure to the 82 damping piece without adjusting the 81 damping screw, reducing the maintenance frequency and lowering the maintenance cost.
