Description

Technical Field

[0001] This utility model relates to the field of medical suspension bridge technology, and more specifically, to a multifunctional dry and wet combined suspension bridge. Background Technology

[0002] Most functional hangers on the market are difficult to move flexibly laterally. If the functional hanger is too close to the bed, it is not conducive to medical staff to rescue the patient, while if it is too far away, it is not conducive to nursing devices to care for the patient, making them very inconvenient to use.

[0003] A search revealed that utility model patent CN 209422331 U discloses a multifunctional wet and dry suspension bridge for ICUs, including a suspension bridge frame. A connecting sleeve is fixedly connected to the top of the suspension bridge frame. Limiting grooves are provided on the left and right sides of the bottom of the suspension bridge frame. A sliding disc is slidably connected inside the limiting groove. By driving the sliding disc to slide inside the limiting groove through a first or second hanger, the extended arm or functional box can be moved laterally, thereby flexibly adjusting the distance between the functional hanger and the bed, achieving the effect of facilitating patient rescue and nursing.

[0004] The aforementioned patent requires manual pushing when moving the hanger, which is quite laborious. Furthermore, when the sliding disc slides within the limiting groove, sliding friction occurs between the sliding disc and the inside of the limiting groove, resulting in significant friction. This is especially problematic when medical devices are placed on the hanger, as moving the hanger can easily cause jamming or interference. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a multifunctional dry and wet combined suspension bridge.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional wet and dry combined suspension bridge, including a suspension rod, the bottom of which is fixedly connected to a suspension bridge track by bolts, a drive assembly installed on the inner side of the suspension bridge track, a hanger assembly installed at the bottom of the drive assembly, the drive assembly including a fixed frame, a drive motor fixedly connected to the right side of the fixed frame, a drive gear fixedly connected to the output shaft of the drive motor, a worm gear movably sleeved on the bottom inner side of the fixed frame, a driven gear fixedly sleeved on the right side outer side of the worm gear, a rotating rod movably sleeved on the top inner side of the fixed frame, a drive gear fixedly sleeved in the middle outer side of the rotating rod, and a transmission worm gear fixedly sleeved on the back outer side of the rotating rod.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 6 As shown, this utility model provides a multifunctional wet and dry combined suspension bridge, including a suspension rod 1. The bottom of the suspension rod 1 is fixedly connected to the suspension bridge track 2 by bolts. A drive assembly 3 is installed on the inner side of the suspension bridge track 2. A hanger assembly 4 is installed at the bottom of the drive assembly 3. The drive assembly 3 includes a fixed frame 301. A drive motor 302 is fixedly connected to the right side of the fixed frame 301. A drive gear 303 is fixedly connected to the output shaft of the drive motor 302. A worm gear 304 is movably sleeved on the bottom inner side of the fixed frame 301. A driven gear 305 is fixedly sleeved on the right side of the outer side of the worm gear 304. A rotating rod 306 is movably sleeved on the top inner side of the fixed frame 301. A drive gear 307 is fixedly sleeved in the middle of the outer side of the rotating rod 306. A transmission worm wheel 308 is fixedly sleeved on the back of the outer side of the rotating rod 306. A movable cavity 201 is opened at the bottom of the suspension bridge track 2. The movable cavity 201 is slidably sleeved with the fixed frame 301.

[0025] In this embodiment, when the hanger assembly 4 needs to be moved laterally, the drive motor 302 is controlled by the control button 401 to drive the drive gear 303 to rotate. The meshing action of the drive gear 303 and the driven gear 305 drives the worm 304 to rotate. The meshing action of the worm 304 and the transmission worm wheel 308 drives the rotating rod 306 to rotate. Then, under the meshing action of the drive gear 307 and the meshing teeth 203, the drive assembly 3 moves laterally along the inner side of the movable cavity 201. During the movement of the drive assembly 3, the first roller 311 and the second roller 312 roll and rub against the inner side of the movable cavity 201 to avoid jamming or interference when the drive assembly 3 moves. Thus, the drive assembly 3 can drive the hanger assembly 4 to move smoothly and steadily according to the actual usage.

[0026] The fixed frame 301 has a first roller 311 movably sleeved on both the front and back sides, and a second roller 312 movably sleeved on both the front and back sides of the bottom of the fixed frame 301. Both the second roller 312 and the first roller 311 are in contact with the inner wall of the movable cavity 201.

[0027] During the movement of the drive assembly 3, the first roller 311 and the second roller 312 roll against the inner wall of the movable cavity 201. The friction is small, which makes the movement of the drive assembly 3 smoother and less prone to jamming.

[0028] In this configuration, the driving gear 303 and the driven gear 305 mesh with each other, and the diameter of the driving gear 303 is smaller than the diameter of the driven gear 305.

[0029] The meshing action of the driving gear 303 and the driven gear 305 increases the output shaft speed and improves the output torque.

[0030] The top of the inner wall of the movable cavity 201 is provided with a rectangular groove 202, and the top of the inner wall of the rectangular groove 202 is provided with meshing teeth 203. The top of the outer side of the drive gear 307 meshes with the meshing teeth 203, and the worm 304 meshes with the transmission worm wheel 308.

[0031] Among them, the left side of the hanger assembly 4 is provided with a control button 401. The control button 401 is electrically connected to the drive motor 302 through a wire. There are two control buttons 401, one to control the drive assembly 3 to move to the left and the other to control the drive assembly 3 to move to the right.

[0032] Working principle and usage process of this utility model:

[0033] When the hanger assembly 4 needs to be moved laterally, the drive motor 302 is controlled by the control button 401 to drive the drive gear 303 to rotate. The meshing of the drive gear 303 and the driven gear 305 drives the worm 304 to rotate. The meshing of the worm 304 and the transmission worm wheel 308 drives the rotating rod 306 to rotate. Then, under the meshing of the drive gear 307 and the meshing teeth 203, the drive assembly 3 moves laterally along the inner side of the movable cavity 201. During the movement of the drive assembly 3, the first roller 311 and the second roller 312 roll and rub against the inner side of the movable cavity 201 to avoid jamming or interference when the drive assembly 3 moves. Thus, the drive assembly 3 can drive the hanger assembly 4 to move smoothly and steadily according to the actual usage.
