Description

Technical Field

[0001] The utility model belongs to the technical field of rehabilitation traction devices, and more specifically, particularly relates to a traction device used for lumbar and cervical vertebra rehabilitation. Background Art

[0002] Rehabilitation traction is a therapeutic technique that stretches and realigns body parts by applying external force or tension. This traction technique is often used in rehabilitation therapy to help restore muscle, ligament and joint function, relieve pain, increase joint mobility, and promote the recovery of injured parts.

[0003] Based on the above, the inventors have found the following problems: most of the current rehabilitation traction devices can only traction a single part, which is relatively simple. When traction is required for multiple parts, multiple devices need to be used, which takes up more space.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and a traction device for lumbar and cervical rehabilitation is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a traction device for lumbar and cervical vertebra rehabilitation to solve the problem that the existing rehabilitation traction device has a relatively single structure.

[0006] The purpose and effect of the traction device for lumbar and cervical vertebra rehabilitation of the utility model are achieved by the following specific technical means:

[0007] A traction device for lumbar and cervical vertebra rehabilitation comprises a mounting plate, a connecting rod is installed on the surface of the mounting plate through a hinge seat, a mounting block is installed on one end of the connecting rod through a hinge seat, a connecting block is installed on one side of the mounting block, a rotating plate is rotatably installed on the surface of the connecting block, a slide groove is installed on the surface of the mounting block, a rack is installed in the slide groove, the rack is connected to a bed board, a slot is provided on the surface of the mounting block, a mounting piece is installed on the bottom of the mounting block, a motor is installed on the surface of the mounting piece, a gear is installed on the surface of the motor, the gear passes through the slot and is connected to the rack, and a cervical vertebra traction mechanism is installed on the surface of the rotating plate.

[0008] Furthermore, an electric cylinder is mounted on the surface of the mounting plate via a hinge seat, and an output end of the electric cylinder is connected to the mounting block via the hinge seat.

[0009] Furthermore, a limiting block is installed in the slide groove, and a limiting groove matching the limiting block is opened on the surface of the rack.

[0010] Furthermore, the cervical traction mechanism includes a collecting box, a fixed rod, a moving rod, a rotating rod, a tensioner and a sling. The collecting box is installed on the surface of the rotating plate, the fixed rod is installed on the surface of the collecting box, the moving rod is installed inside the fixed rod, the rotating rod is rotatably installed on the surface of the moving rod, the tensioner is installed on the surface of the rotating rod, the output end of the tensioner is installed on the sling, and the sling is located in the collecting box.

[0011] Furthermore, a group of slideways are installed on the surface of the collecting box, a sliding plate is installed in the slideway, and a notch matching the output end of the tensioner is opened on the surface of the sliding plate.

[0012] Furthermore, a first adjusting hand wheel is installed on the surface of the connecting block, a second adjusting hand wheel is installed on the surface of the fixing rod, and a third adjusting hand wheel is installed on the surface of the rotating rod.

[0013] Furthermore, arm fixing rollers are installed on the surface of the rotating plate, and foot fixing rollers are installed on the surface of the bed board.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model uses a mounting block, a slide groove, a rack, a bed board, a slot, a mounting piece, a motor and a gear in coordination. When the motor is started, the gear is driven to rotate, the gear rotation drives the rack to move in the slide groove, and the rack movement drives the bed board to move, thereby pulling the patient.

[0016] Through the coordinated use of the collecting box, the fixed rod, the moving rod, the rotating rod, the tensioner and the sling, when the cervical vertebra needs to be pulled, you only need to adjust the bed board to a horizontal state, and then adjust the rotating board to a vertical state, and then lift the moving rod. The lifting of the moving rod will drive the lifting of the rotating rod, and the lifting of the rotating rod will drive the tensioner to move the sling out of the collecting box, and then rotate the rotating rod, and then fix the sling to the head, and then pull the tensioner to pull the cervical vertebra. Through the above design, you can quickly switch from waist traction to cervical vertebra traction, which improves the convenience of use and reduces the usage area.
