Description

1. Technical field:

[0001] The utility model relates to the technical field of medical equipment design, and in particular to a lumbar and cervical vertebra rehabilitation device. 2. Background technology:

[0002] At present, there are not many devices on the market for the protection and preventive exercise of the lumbar and cervical spine. Most people will not consciously protect the lumbar and cervical spine. Only when the lumbar and cervical spondylosis is so serious that it affects their lives will they think of treatment, rather than preventing lumbar diseases early. The lumbar and cervical rehabilitation devices on the market are basically based on traction therapy. This type of rehabilitation device can be roughly divided into two types, one is a home portable traction rehabilitation device, and the other is a fixed traction rehabilitation device. The solid traction rehabilitation device is larger in size, and its rehabilitation principle is to use the neck support on the device to traction the neck for stretching. The home portable traction rehabilitation device is smaller in size, has a large sales volume, and has many forms of exercise, including cervical stretching, nodding and tilting the head. This type of rehabilitation device is considered to have relatively complete functions in the market, but it can only complete one or two neck movements and cannot complete all the movements of the human neck, such as left and right deflection of the neck and rotation of the neck. Moreover, this type of rehabilitation device can only be operated manually, which is difficult to operate and does not have the function of automatically completing neck movements. 3. Utility Model Content:

[0003] The purpose of the utility model is to realize left and right swinging of the head, rotation of the head, nodding and tilting of the head, stretching of the cervical spine and fixation of the lumbar spine, so as to exercise the lumbar and cervical spine in all directions, relieve the fatigue of the lumbar and cervical spine, prevent the lumbar and cervical spine from being in an incorrect posture for a long time, and restore the normal physiological curve of the lumbar and cervical spine.

[0004] In order to achieve the above object, the utility model provides a lumbar and cervical rehabilitation device, which consists of 6 parts: a base, a rotating slider, a forehead neck support, an occipital support, a lumbar fixation belt and a transmission part. The base is made of silicone rubber material, the pillar is made of light hard plastic material, the forehead neck support is made of silicone rubber material, the occipital support is made of silicone rubber material, and the lumbar fixation belt is made of hard material. The base is composed of a shoulder sleeve and a pillar, the shoulder sleeve fits the neck and shoulder, and the pillar is connected to the shoulder sleeve and supports other parts. The rotating slider cooperates with the forehead neck support and is sleeved on the neck. There is a partial gear structure behind the rotating slider, which is meshed and connected with the gear behind the pillar. The occipital support contacts the back of the head and the neck, and racks are installed on both sides of it, and the racks are driven by the gears on both sides. The forehead neck support is connected to the motor through a rectangular shaft and a gear. The lumbar fixation belt is connected to the pillar through a strap, and the lumbar fixation belt can realize the waist fixation function.

[0005] Furthermore, the base is composed of a shoulder sleeve and a pillar, the shoulder sleeve is the lower part of the base, and the pillar is the upper part of the base. There are several small holes and two left and right grooves on the shoulder sleeve. The small holes are connected to the pillar, and the left and right grooves are for the rack to move up and down inside it to achieve the height adjustment of the occipital support. In addition, there is an opening in the front of the shoulder sleeve as an entrance for the neck. The pillar has four rivets for connecting with the shoulder sleeve. There are two T-shaped grooves from top to bottom on the left and right sides, which serve as tracks for the rack to move up and down. In addition, there is a gear box on the right side of the pillar, which contains a gear for controlling the forehead neck support. There is also a gear box at the back of the pillar, which contains a rotating gear.

[0006] Furthermore, the rear of the rotating slider structure has a partial gear structure that meshes with the gear at the rear of the pillar.

[0019] The present invention is described in detail below in conjunction with specific embodiments.

[0020] like Figures 1 to 8 The utility model provides a lumbar and cervical rehabilitation device, including a base, a rotating slider 24, a forehead neck support 22, an occipital support 23, and a lumbar fixation belt 40. The base includes a shoulder sleeve 21 and a support 6. The shoulder sleeve 21 is the lower part of the base and directly contacts the user's shoulder. The shoulder sleeve 21 has several small holes and two left and right grooves, such as Figure 4 These small holes are connected to the pillars 6, and the left and right grooves are for the racks on the occipital support 23 to move up and down inside them to achieve the height adjustment of the occipital support 23, such as Figure 7 The shoulder cover 21 also has an opening at the front, which serves as an entrance for the neck. The support 6 has four rivets for connecting with the shoulder cover 21. There are two T-shaped grooves from top to bottom on the left and right sides, which serve as tracks for the rack on the occipital support 23 to move up and down. In addition, there is a gear box 26 on the right side of the support 6, which contains a gear for controlling the forehead support 22 to achieve control of the forehead support 22. There is also a gear box 13 at the rear of the support 6, which contains a rotating gear 12 to achieve rotation control of the entire device.

[0021] In this embodiment, if Figure 2 and Figure 6 The rear of the rotating slider 24 structure has a partial gear structure for realizing the rotation action. Specifically, the gear structure is meshed with the gear 12 behind the pillar, and the motor 1 drives the small gear 12 to rotate, and the small gear 12 then drives the large gear behind the rotating slider 24 to rotate, thereby realizing the rotation of the rotating slider 24. There is a gap between the rotating slider 24 and the pillar 6 to reserve a rotation space during rotation so that the parts do not interfere with each other during rotation. There is a T-shaped connection device at the lower right of the rotating slider 24 for connecting the forehead neck support 22.

[0022] In this embodiment, if Figure 1 and Figure 5 In the embodiment, the forehead collar 22 is provided with a rotating track on its left and right sides, and a concave groove is provided on its left side, which can cooperate with the base to play a fixing role. However, there is no concave groove on the right side, so that it can be separated from the base.

[0023] In this embodiment, if Figure 1 and Figure 3 When the two racks of the occipital support 23 move upward at the same time, the cervical spine can be stretched. When the two racks of the occipital support 23 move in opposite directions, the head can be swung left and right.

[0024] In this embodiment, if Figure 1 In the embodiment, the lumbar fixing belt 40 has three rows of holes and one row of buttons, which can be used by people with different waist circumferences.

[0025] In this embodiment, if Figure 8 The design of this device takes into account the physiological characteristics and range of motion of the human body to ensure that the range of motion of the device does not cause excessive movement of the neck. In addition, a mechanical self-locking function is set when designing the device. When the device rotates to a certain position, it will be blocked by the raised cylinder and cannot move anymore, thus avoiding neck injury caused by excessive rotation.

[0026] The left and right swinging function of the neck is completed by the motor 3 and the motor 4. When the motor 3 rotates forward, it drives the left rack of the neck occipital support 23 to move upward, and the motor 4 rotates reversely at the same time, driving the rack of the neck occipital support 23 to move downward, completing the right head swinging action; when the motor 3 rotates reversely, it drives the left rack of the neck occipital support 23 to move downward, and the motor 4 rotates forward at the same time, driving the rack of the neck occipital support 23 to move upward, completing the left head swinging action.

[0027] The neck rotation function is completed by the motor 1 alone. When the motor 1 rotates forward, the small gear 12 drives the large gear on the rotating slider 24 to rotate, completing the left head rotation action; when the motor 1 rotates backward, the small gear 12 drives the large gear on the rotating slider 24 to rotate, completing the right head rotation action.

[0028] The nodding and reclining function is accomplished by motors 2, 3, and 4. Motors 3 and 4 rotate forward, driving gear 19 to rotate forward, and gear 19 drives the rack of occipital support 23 to move upward, so that occipital support 23 moves upward, while motor 2 drives gear 25 to rotate forward, and gear 27 drives the rectangular shaft to rotate forward, and the rectangular shaft gives a counterclockwise torque to the forehead support 22, so that the forehead support 22 rotates counterclockwise by a certain angle, completing the nodding action, and the reclining action is similar to this.

[0029] The above shows and describes the basic principle and main features of the utility model. The mechanism proposed in this embodiment can realize four kinds of movements such as left and right swing of the head, left and right rotation, nodding and tilting the head, and cervical spine stretching, as well as waist fixation and other functions. The device can correct the waist and cervical spine to the correct physiological angle, and at the same time can perform strength training on the neck, promote the recovery of neck activity function and strength, so as to achieve the purpose of preventing and treating cervical spondylosis.
