Description

Technical Field

[0001] This utility model relates to the field of medical treatment bed technology, and in particular to a lifting transmission mechanism for a medical treatment bed. Background Technology

[0002] In medical diagnosis, surgical treatment, and rehabilitation care, medical treatment beds are one of the core pieces of equipment. Their lifting function directly affects the convenience of diagnosis and treatment operations, the accuracy of patient positioning, and comfort.

[0003] In the existing technology, when the bed board needs to be raised, the caregiver can only operate the crank at the foot of the bed. However, in actual use, when the caregiver is watching the patient on one side of the bed, they have to get up and walk to the foot of the bed to operate it every time an adjustment is needed, which is very inconvenient. Therefore, a lifting transmission mechanism for medical treatment beds has been designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lifting and transmission mechanism for a medical treatment bed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lifting transmission mechanism for a medical treatment bed includes a bed frame. A fixed bed board is fixedly connected to the inner side of one top end of the bed frame, and a rotatable bed board is rotatably connected to the other inner end of the bed frame. Connecting columns are fixedly connected to both ends of both sides of the bed frame. A common support rod is fixedly connected to the bottom of the two connecting columns on the same side. Two first connecting plates are fixedly connected between the two support rods near the rotatable bed board. A common lead screw is rotatably connected between the middle of the two first connecting plates. A first cylinder is fixedly connected to the end of the lead screw near the fixed bed board through the first connecting plate. A bevel gear is fixedly threaded onto the lead screw near the first cylinder. A fixed plate is fixedly connected to the middle of the first connecting plate near the first cylinder, and a rotating rod is rotatably mounted on the fixed plate. The fixed plate has a circular hole adapted to the rotating rod. A bevel spur gear is fixedly connected to the end of the rotating rod near the bevel gear, and the bevel spur gear meshes with the bevel gear. A second cylinder is fixedly connected to the other end of the rotating rod.

[0007] Furthermore, a sleeve is fixedly connected to the end of the inner wall of both the first cylinder and the second cylinder away from the bevel gear, and multiple slots are equally spaced on the inner circumference of the sleeve.

[0008] Preferably, the two support rods are fixedly connected to the same round rod near the rotatable bed board. The two ends of the round rod are rotatably fitted with first connecting rods. The tops of the two first connecting rods are rotatably connected to second connecting rods. The tops of the two second connecting rods are rotatably connected to connecting blocks, and each connecting block is fixedly connected to the bottom of the rotatable bed board. The middle of the two first connecting rods is fixedly connected to the same crossbar, and the middle of the crossbar is rotatably fitted with a U-shaped drive rod. One end of the bottom of the U-shaped drive rod is rotatably connected to a screw block.

[0009] Preferably, the screw block is screwed onto the lead screw, and a lead screw nut that matches the lead screw is fixedly sleeved in the middle of the screw block.

[0010] Preferably, two second connecting plates are fixedly connected between the ends of the two support rods near the fixed bed board. The same first rotating rod is slidably sleeved in the middle of the two second connecting plates. Both second connecting plates have a circular hole adapted to the first rotating rod. The end of the first rotating rod near the first cylinder is slidably connected to the inner wall of the first cylinder. A first locking block is fixedly connected to the circumferential surface of the end of the first rotating rod inside the first cylinder, and the first locking block is adapted to the locking groove. A first crank is fixedly connected to the other end of the first rotating rod.

[0011] Furthermore, a fixing block is fixedly connected to one of the support rods near the rotating rod, and a second rotating rod is slidably sleeved on the fixing block. A circular hole adapted to the second rotating rod is opened on the fixing block. One end of the second rotating rod near the second cylinder is slidably connected to the inner side of the second cylinder, and a locking block is fixedly connected to the circumferential surface of the second rotating rod near the second cylinder. The second locking block is adapted to the locking groove, and a second crank is fixedly connected to the other end of the second rotating rod.

[0012] Furthermore, both ends of the bottom of the two support rods are fixedly connected with casters equipped with brakes.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through its dual-drive structure design—a first crank at the foot of the treatment bed and a second crank on the side—completely solves the drawback of existing treatment beds that can only be operated from a single position. When caregivers are monitoring the patient at the bedside, they do not need to get up and move to the foot of the bed; they can simply pull and turn the second crank on the side to adjust the bed's height. Similarly, when medical staff are performing diagnostic and treatment procedures at the foot of the bed, they can quickly adjust the patient's position using the first crank, greatly reducing the complexity of the operational process and improving the efficiency of nursing and diagnostic care.

[0015] 2. The first and second cranks adopt a detachable locking structure. By pulling the rotating rod, the locking block engages with the slot in the sleeve to achieve power connection. When not in use, the cranks can be reset to separate the locking block, preventing accidental movement of the bed board due to accidental activation. This design allows the two cranks to operate independently without interference, and the operating end can be flexibly selected according to the actual use scenario, adapting to the diverse needs of different medical scenarios.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5A lifting transmission mechanism for a medical treatment bed includes a bed frame 1. A fixed bed board 101 is fixedly connected to the inner side of one top end of the bed frame 1, and a rotatable bed board 102 is rotatably connected to the other inner end of the bed frame 1. Connecting columns 2 are fixedly connected to both ends of both sides of the bed frame 1. The bottom of the two connecting columns 2 on the same side is fixedly connected to the same support rod 3. Two first connecting plates 5 are fixedly connected between the two support rods 3 near the rotatable bed board 102. A lead screw 501 is rotatably connected between the middle of the two first connecting plates 5. The end of the lead screw 501 near the fixed bed board 101 passes through the first connecting plate 5 and is fixedly connected to a first cylinder 9. A bevel gear 502 is fixedly threaded near the first cylinder 9. A fixing plate 10 is fixedly connected to the middle of the first connecting plate 5 near one end of the first cylinder 9, and a rotating rod 1001 is rotatably sleeved on the fixing plate 10. The fixing plate 10 has a circular hole that matches the rotating rod 1001. A bevel spur gear 1002 is fixedly connected to one end of the rotating rod 1001 near the bevel gear 502, and the bevel spur gear 1002 meshes with the bevel gear 502. A second cylinder 1003 is fixedly connected to the other end of the rotating rod 1001. The cooperation between the first cylinder 9 and the fixing plate 10 ensures that the first crank and the second crank do not interfere with each other when they are working.

[0024] Furthermore, sleeves 11 are fixedly connected to the inner walls of the first cylinder 9 and the second cylinder 1003 at the ends away from the bevel gear 502, and multiple slots 1101 are equally spaced on the inner circumference of the sleeves 11.

[0025] Preferably, the two support rods 3 are fixedly connected to the same round rod 4 near the rotatable bed board 102. The two ends of the circumference of the round rod 4 are rotatably fitted with first connecting rods 401. The tops of the two first connecting rods 401 are rotatably connected with second connecting rods 403. The tops of the two second connecting rods 403 are rotatably connected with connecting blocks 404. Each connecting block 404 is fixedly connected to the bottom of the rotatable bed board 102. The middle of the two first connecting rods 401 is fixedly connected to the same crossbar 402. The middle of the crossbar 402 is rotatably fitted with a U-shaped drive rod 405. The bottom end of the U-shaped drive rod 405 is rotatably connected with a screw block 406.

[0026] Furthermore, the screw block 406 is screwed onto the lead screw 501. A lead screw nut that matches the lead screw 501 is fixedly sleeved in the middle of the screw block 406. By moving the screw block 406, the included angle between the first connecting rod 401 and the second connecting rod 403 changes, which allows the rotatable bed board 102 to rotate and be lifted.

[0027] Furthermore, two second connecting plates 6 are fixedly connected between the ends of the two support rods 3 near the fixed bed board 101. The same first rotating rod 7 is slidably sleeved in the middle of the two second connecting plates 6. Both second connecting plates 6 have round holes that are adapted to the first rotating rod 7. The end of the first rotating rod 7 near the first cylinder 9 is slidably connected to the inner wall of the first cylinder 9. The circumferential surface of the end of the first rotating rod 7 located inside the first cylinder 9 is fixedly connected to a first locking block, and the first locking block is adapted to the locking groove 1101. The other end of the first rotating rod 7 is fixedly connected to a first crank handle.

[0028] Furthermore, a fixing block 801 is fixedly connected to one of the support rods 3 near the rotating rod 1001, and a second rotating rod 8 is slidably sleeved on the fixing block 801. A circular hole adapted to the second rotating rod 8 is opened on the fixing block 801. One end of the second rotating rod 8 near the second cylinder 1003 is slidably connected to the inner side of the second cylinder 1003, and a locking block is fixedly connected to the circumferential surface of the second rotating rod 8 near the second cylinder 1003. The second locking block is adapted to the locking groove 1101, and a second crank is fixedly connected to the other end of the second rotating rod 8. By pulling the second rotating rod 8, the second locking block is engaged with the locking groove 1101, which causes the second rotating rod 8 to rotate, thereby driving the rotation of the lead screw 501 and driving the rotatable bed board 102.

[0029] In this embodiment, both ends of the bottom of the two support rods 3 are fixedly connected with universal wheels 301 with brakes.

[0030] Working principle: When using this mechanism, if it is necessary to lift the rotatable bed board 102, the first crank or the second crank can be selected according to the position. When the first crank is selected, pulling the first crank causes the first rotating rod 7 to move outward. At this time, the first locking block inside the first cylinder 9 will slide into the locking groove 1101. The locking groove 1101 is chamfered to facilitate the sliding of the first and second locking blocks. Then, rotating the first crank causes the first connecting plate 5 to rotate due to the rotation of the first rotating rod 7 and the first cylinder 9. The rotation of the lead screw 501 causes the screw block 406 to move closer to one end of the bevel gear 502. Through the movement of the screw block 406, The U-shaped drive rod 405 supports the crossbar 402, causing the top of the crossbar 402 to move upward. Connected by the first connecting rod 401, the rotatable bed board 102 rotates upward under the push of the second connecting rod 403. After completion, the first crank is reset, causing the first locking block inside the first cylinder 9 to separate from the locking groove 1101. When the second crank is needed, it is pulled to engage the second locking block on the second rotating rod 8 with the locking groove 1101 in the second cylinder 1003. Rotating the second crank drives the rotatable bed board 102 to move through the meshing of the bevel spur gear 1002 and the bevel gear 502. The two cranks make it convenient for caregivers to use.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
