Description

Technical Field

[0001] The invention relates to the technical field of traction bed adjustment mechanisms, in particular to an angle adjustment mechanism for a medical traction bed. Background Art

[0002] A traction bed is a medical device, usually used in institutions such as hospitals and rehabilitation centers, for the treatment of spinal diseases, fractures, joint dislocations and other related diseases. During the use of the traction bed, the patient's lying posture needs to be adjusted so that the patient can perform traction operations at different angles, making it easier to traction different parts of the body. At this time, an angle adjustment mechanism is needed to adjust the patient's lying position.

[0003] Considering that during the traction process, the only adjustable parts of the human body are the bending adjustment of the back and lower limbs, or the adjustment of the bone joints between the thigh and calf, some angle adjustment mechanisms for adjusting the back and bone joints can be used.

[0004] Generally, manual adjustment of traditional angle adjustment mechanisms is laborious during actual adjustment. With technological advancement, electric drive structures have emerged. However, electric drive structures cannot be manually adjusted, which may cause problems with the electric drive and prevent it from being used again in a short period of time. At the same time, it is difficult to quickly repair it during emergency use, thereby reducing the safety of the traction bed. If a separate manual operation structure is provided for emergency use, the overall drive structure will have two sets, increasing production and use costs. The two sets of drive structures will occupy a large amount of installation space, thereby greatly reducing the overall installation and subsequent maintenance and space utilization, which is very inconvenient. In addition, when adjusting the leg flexion, two rotating plates that rotate with each other are often rotated upward for adjustment. However, this method often uses a drive extrusion upward rotation method for adjustment, but the extrusion direction can be upward or downward. When the downward rotation trend is strong, the rotating plate needs to be manually pulled upward. The frequent downward rotation extrusion force also shortens the service life of the overall components and increases the use cost.

[0005] In summary, it is necessary to propose a medical traction bed angle adjustment mechanism to solve the above problems. Summary of the Invention

[0064] The overall working principle of the above is:

[0065] During use, when the adjustment plate 29 needs to be rotated, the first motor 21 is started, so that the second rotating rod 22 rotates, which in turn drives the first gear 24 to rotate, which in turn drives the second gear 26 to rotate, which in turn drives the third rotating rod 25 and the first rotating rod 23 to rotate, which in turn drives the rotating block 28 to rotate, and at the same time drives the adjustment plate 29 to rotate, so that the angle of the adjustment plate 29 can be adjusted;

[0066] When manual adjustment is required, the first threaded clamping rod 214 is separated from the first screw hole 212 and the second screw hole 213. At this time, the first rotating rod 23 is rotated, which can drive the rotating block 28 to rotate, and then drive the adjusting plate 29 to rotate;

[0067] After the rotation is completed, the first screw 219 is rotated so that the first screw 219 can drive the rectangular block 220 and the arc block 221 to move, and then fit the auxiliary circular block 216 for limiting and fixing;

[0068] The second motor 315 is started, so that the second motor 315 can drive the auxiliary rotating rod 316 to rotate, and then drive the second screw 318 to rotate, so that the second screw 318 can drive the screw hole block 324 to move, and then drive the rectangular slider 326 to move, and then drive the rectangular connecting plate 312 to move, so that the second rotating block 311 can rotate on the third fixed rod 310, and at the same time squeeze the first rotating block 37 on the second rotating plate 38 to rotate on the outer surface of the second fixed rod 36, and at the same time drive the first rotating plate 34 to rotate on the outer surface of the first fixed rod 33, and at this time the return spring 331 in the compressed state can drive the sliding round rod 328 to push upward, so that the second rotating plate 38 and the first rotating plate 34 rotate upward;

[0069] When manual adjustment is required, the second threaded clamping rod 322 is separated from the third screw hole 320 and the fourth screw hole 321, and the operating knob 332 is rotated so that the second screw rod 318 can drive the screw hole block 324 to move;

[0070] When the angle of the adjustment plate 29 is adjusted, the ground contact rod 412 is rotated so that the auxiliary rotating block 43 drives the rotating round rod 42 to rotate. After rotating to the appropriate position, the auxiliary screw 49 is rotated so that the rubber round block 410 and the rubber ring block 48 are squeezed and fixed. At this time, the ground contact rod 412 is pulled so that the sliding rod 45 slides on the inner wall of the fixed cylinder 44, and then the threaded extrusion rod 46 is rotated to fix the sliding rod 45. At this time, the ground contact rod 412 is rotated to move on the outer surface of the adjusting screw 411, and then the position of the ground contact rod 412 can be adjusted.

[0071] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
