Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an electric power drive device for a traction bed. Background Technology

[0002] A traction bed is a medical device used for physiotherapy and rehabilitation, widely used for the treatment of clinical symptoms such as leg muscle atrophy, lumbar disc herniation, and cervical spondylosis caused by weakness in walking. Existing traction beds, whether used in hospitals or medical institutions, or for home physiotherapy and rehabilitation, generally have drive mechanisms that can be categorized as manual force control, electric automatic control, or a combination of both.

[0003] In existing technologies, when users need to adjust the angle of the backrest, they need to manually push and adjust it, which is time-consuming and laborious. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where users need to manually push the adjustment when they need to adjust the backrest angle, which is time-consuming and laborious. This invention proposes an electric power drive device for traction beds.

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

[0006] An electric power drive device for a traction bed, comprising:

[0007] Bed frame;

[0008] Multiple fixed plates are symmetrically and slidably installed in the bed body. A bed board is fixedly installed between the multiple fixed plates. A backrest is rotatably connected to one end of the bed board. An adjustment seat is fixedly installed at the bottom of the bed board. An adjustment motor is fixedly installed on one side of the adjustment seat.

[0009] The adjustment mechanism, located inside the adjustment seat, is used to adjust the angle of the backrest;

[0010] The traction mechanism, located inside the bed, is used to move the bed board by traction.

[0011] Furthermore, the traction mechanism includes two symmetrically rotatably connected movable screws within the bed body. The two movable screws are threadedly connected to multiple fixed plates, and a sprocket is fixedly connected to one end of each of the two movable screws. A chain meshes between the two sprockets.

[0012] Furthermore, a hanging plate is fixedly installed at one end of the bed, and a moving motor is fixedly connected to the bottom of the hanging plate, with one of the moving screws fixedly connected to the output shaft of the moving motor.

[0013] Furthermore, the adjustment mechanism includes an adjustment screw rotatably connected to the adjustment seat, the adjustment screw being fixedly connected to the output shaft of the adjustment motor, an adjustment block being threadedly connected to the adjustment screw, the adjustment block being slidably connected to the adjustment seat, and push plates being fixedly connected to both sides of the adjustment block.

[0014] Furthermore, each of the two push plates has a slider fixedly connected to one end, and each of the two sliders has a hinge plate hinged to one side. One end of each hinge plate is hinged to the two sides of the backrest.

[0015] Furthermore, each of the four corners of the bottom of the bed is fixed with a caster wheel, and a controller is located on the front side of the bed.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] 1. In this solution, a chain meshes between the two sprockets, causing the two moving screws to rotate synchronously. The two moving screws drive multiple fixed plates to move, and the multiple fixed plates pull the bed board to move, thereby achieving the effect of traction movement.

[0018] 2. In this solution, the two sliders are connected to the two hinge plates, which move the bottom ends of the two hinge plates and cause the top ends of the two hinge plates to tilt upwards. The two hinge plates cause the backrest to rotate around the bed board as a fulcrum, thereby achieving the effect of automatically adjusting the angle of the backrest.

[0019] This utility model has a simple structure and can automatically adjust the angle of the backrest by using an adjustable motor, saving time and effort and making it convenient for people to use. Attached Figure Description

Detailed Implementation

[0024] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this embodiment, and not all embodiments.

[0025] Example 1

[0026] Reference Figures 1-3 An electric power drive device for a traction bed, comprising:

[0027] Bed 1;

[0028] Multiple fixed plates 2 are symmetrically slidably installed inside the bed frame 1. A bed board 3 is fixedly installed between the multiple fixed plates 2. A backrest 4 is rotatably connected to one end of the bed board 3. An adjustment seat 5 is fixedly installed at the bottom of the bed board 3. An adjustment motor 6 is fixedly installed on one side of the adjustment seat 5.

[0029] In this embodiment, a traction mechanism is located inside the bed body 1 and is used to traction and move the bed board 3. The traction mechanism includes two symmetrically rotatably connected movable screws 7 inside the bed body 1. The two movable screws 7 are respectively threadedly connected to multiple fixed plates 2. One end of each of the two movable screws 7 is fixedly connected to a sprocket 8. A chain 9 is meshed between the two sprockets 8. A hanging plate 10 is fixedly installed at one end of the bed body 1. A movable motor 11 is fixedly connected to the bottom of the hanging plate 10. One of the movable screws 7 is fixedly connected to the output shaft of the movable motor 11. Since the chain 9 meshes between the two sprockets 8, the two movable screws 7 rotate synchronously. The two movable screws 7 drive the multiple fixed plates 2 to move, and the multiple fixed plates 2 traction the bed board 3 to move, thereby achieving the effect of traction and movement.

[0030] In this embodiment, the adjustment mechanism is located inside the adjustment seat 5 and is used to adjust the angle of the backrest 4. The adjustment mechanism includes an adjustment screw 16 rotatably connected to the adjustment seat 5. The adjustment screw 16 is fixedly connected to the output shaft of the adjustment motor 6. An adjustment block 17 is threadedly connected to the adjustment screw 16. The adjustment block 17 is slidably connected to the adjustment seat 5. Push plates 18 are fixedly connected to both sides of the adjustment block 17. A slider 19 is fixedly connected to one end of each of the two push plates 18. A hinge plate 20 is hinged to one side of each of the two sliders 19. One end of each hinge plate 20 is hinged to both sides of the backrest. The two sliders 19 use the hinges with the two hinge plates 20 to drive the bottom ends of the two hinge plates 20 to move, and cause the top ends of the two hinge plates 20 to tilt upward. The two hinge plates 20 drive the backrest 4 to rotate around the bed board 3 as the fulcrum, thereby achieving the effect of automatically adjusting the angle of the backrest 4.

[0031] In this embodiment, four corners of the bottom of the bed body 1 are fixed with casters 13, and a controller 12 is provided on the front side of the bed body 1.

[0032] The implementation principle of the electric power drive device for a traction bed in this embodiment is as follows: First, the controller 12 starts the moving motor 11, so that the output shaft of the moving motor 11 drives one of the moving screws 7 to rotate. Since the two sprockets 8 are meshed with a chain 9, the two moving screws 7 rotate synchronously. The two moving screws 7 drive multiple fixed plates 2 to move, and the multiple fixed plates 2 pull the bed board 3 to move, thereby achieving the effect of traction movement. When it is necessary to adjust the angle of the backrest 4, the controller 12 starts the adjustment motor 6, so that the output shaft of the adjustment motor 6 drives the adjustment screw 16 to rotate. The adjustment screw 16 drives the adjustment block 17 to move. The adjustment block 17 drives two fixedly connected push plates 18 to move horizontally. The two push plates 18 drive two sliders 19 to move on the adjustment seat 5. The two sliders 19 use the hinges between themselves and the two hinge plates 20 to drive the bottom ends of the two hinge plates 20 to move, and cause the top ends of the two hinge plates 20 to tilt upward. The two hinge plates 20 drive the backrest 4 to rotate around the bed board 3 as the fulcrum, thereby achieving the effect of automatically adjusting the angle of the backrest 4.

[0033] Example 2

[0034] Example 2 is the same as Example 1 in the rest, except that: multiple electric push rods 14 are fixedly provided at the bottom of the bed 1, and two stabilizing plates 15 are fixedly connected to the bottom ends of the multiple electric push rods 14 respectively. The multiple electric push rods 14 drive the two stabilizing plates 15 to move downward and contact the ground, thereby achieving the effect of braking and stabilizing the bed 1. All structural shapes, sizes and materials of Example 1 are included in this application. In order to meet specific usage conditions, they can be selected and adjusted. The attached drawings are schematic structural diagrams, and the actual dimensions can be appropriately adjusted.
