Background technique

Cervical and lumbar diseases were originally a common disease among middle-aged and elderly people. However, due to the accelerated pace of life and increasing competitive pressure, office workers and students now sit or work at desks for a long time, and most of them are unhealthy sitting postures. It makes the patients of cervical and lumbar spondylosis tend to be younger. This brings a lot of inconvenience to the patient, and even the rapid deterioration of the body cannot participate in work. At present, the ways of domestic development of this related health care mainly include long-term drug therapy and bone massage therapy in traditional Chinese medicine. Drug therapy will bring great side effects, and massage therapy needs specialized technicians to engage in and is not popular; Corresponding large-scale equipment has also been developed for treatment, but this is only limited to hospitals and other medical units. Patients need to go to the hospital for treatment intermittently, which is necessary for severe patients; Between the family and the hospital, a lot of time is wasted and a certain amount of medical expenses must be paid.

For the traction chair, there have been many corresponding technical devices in the society. One part is mainly the traction therapy device loaded on the neck, which is unhealthy for users: it can only treat the cervical spine, not the lumbar spine, and the overall effect is not good; although the other part can stretch the cervical and lumbar spine at the same time , but either the overall device is bulky and difficult to move and store, or the overall installation is relatively complicated, and there are many uncertain factors, which affect the use of users in actual life.

Detailed ways

Embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

Referring to Figure 1-5, a foldable cervical and lumbar spine manual traction chair includes a seat board 6, a backrest 4 and a transmission system, a backrest 4 is provided on one side of the seat board, armrests 5 and 14 are provided on both sides of the backrest, and the front end of the armrest is The outside is provided with handle 10 and rocking arm 11, and backrest top is provided with headrest 2, and handle is used for controlling transmission system, and transmission system controls headrest to move up and down, and headrest is provided with fixing belt 1. The transmission system includes a gear transmission system and a worm gear transmission system. The gear transmission system includes a driving gear 8, a toothed belt 9 and a driven gear 7 arranged inside the handle, and the driving gear is fixedly connected with the handle. The driving gear drives the driven gear 7 to rotate through the toothed belt 9; the worm gear transmission system includes a worm 12, a worm wheel 13 and a sleeve 15 arranged inside the backrest, the worm is connected with the driven gear, and the driven The gear drives the worm to rotate, the worm drives the worm wheel to rotate, and the worm wheel drives the sleeve fixedly connected to the headrest to move up and down. The two sides of the sleeve are provided with guide posts 3, 16.

When using the utility model, first the traction chair is opened and placed on an ordinary seat for fixing, the person sits on the seat plate 6, leans against the backrest 4, and the head is closely attached to the headrest 2, and the fixing belt 1 Fix it on the neck, put both hands forward lightly on the armrests 5 and 14, open the handle 10 with the right hand, hold the handle and manually swing the rocker arm 11 in a circle, the driving gear 8 rotates, the toothed belt 9 rotates accordingly, and drives the driven gear at the same time 7 rotates, the driven gear 7 drives the worm 12 to rotate, and the worm wheel 13 is driven accordingly, and the rotation of the worm wheel 13 drives the sleeve 15 to move upward along the direction of the guide columns 3 and 16, and the sleeve 15 is fixed on the headrest 2, so that The headrest 2 moves upward together with the fixing belt 1, thereby exerting an upward force on the spine, relieving the pain caused by the cervical and lumbar spondylosis, and at the same time well promoting the rehabilitation of the cervical and lumbar spondylosis.

When the user does not need to use the traction chair, as shown in Figure 6, the backrest 4, seat plate 6, armrest 5, 14 can be folded through the rotating shaft between the seat surface and the backrest and the rotating shaft between the backrest and the armrest, Reduces the space taken up by the traction chair, which facilitates movement and storage.
