Description

Technical Field

[0001] The invention belongs to the technical field of neck traction devices, and in particular relates to a neck traction device for cervical vertebra care. Background Art

[0002] A neck traction device, also known as a cervical traction device, is a medical device used to treat cervical spondylosis. The basic function of a neck traction device is to relax the muscles around the spine and relieve intervertebral pressure. Through traction, it can increase the intervertebral space and intervertebral foramen, reduce or even relieve the stimulation and compression of the nerve roots, relieve muscle spasms, restore the balance of the cervical spine, reduce the intradiscal pressure, and buffer the pressure of the intervertebral disc to the surrounding areas.

[0003] In the Chinese patent with publication number CN201533885U, a clothes hanger type multi-angle neck traction device is mentioned, which includes a base, a lifting chair, a hollow column connected to the base, a cross bar connected to the top of the hollow column with a force node, a buffer spring, a weight scale, a traction rope, a pulley, a traction spool, a reducer, a force adjustment handle, an adjustable length belt connecting the top cross bar and the traction belt hanging rod, a traction belt hanging rod, a traction belt, and a clothes hanger plate. The utility model provides a clothes hanger type multi-angle neck traction device, which is a dual-purpose item and is usually a practical clothes hanger.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] See also Figure 1 - Figure 6 As shown, a neck traction device for cervical vertebra care, comprising:

[0034] Base 1;

[0035] One end of the base 1 is fixedly connected to a fixing frame 4, the top of the fixing frame 4 is tightly attached to an adjusting structure 5, one end of the fixing frame 4 is fixedly connected to two connecting plates 6, and a first limiting wheel 7 is movably interlaced and connected between the two connecting plates 6, a traction rope 8 is sleeved between the adjusting structure 5 and the first limiting wheel 7, and a fixing structure 9 is sleeved at the bottom end of the traction rope 8;

[0036] The fixing structure 9 includes a limiting frame 91, a positioning structure 92, a fixing belt 93, a supporting structure 94, a connecting block 95 and a screw 96. The positioning structure 92 is movably connected to both sides of one end of the limiting frame 91, the fixing belt 93 is fixedly connected to both sides of the top of the limiting frame 91, the connecting block 95 is fixedly connected to the other end of the limiting frame 91, the screw 96 is threadedly connected in the connecting block 95, the supporting structure 94 is connected to the top bearing of the connecting block 95, and the fixing belt 93 is sleeved with the traction rope 8;

[0037] A support frame 2 is fixedly connected to one side of the bottom end of the base 1, a bottom end of the support frame 2 is fixedly connected to a base frame 3, a control box 10 is fixedly connected between the fixed frame 4 and the support frame 2, a rotating wheel 11 is movably connected to one side of the inner wall of the control box 10, and a driver 12 is fixedly connected to the rotating wheel 11 and the other side of the inner wall of the control box 10;

[0038] One end of the traction rope 8 away from the fixed structure 9 passes through the bottom of the fixed frame 4 and the top of the control box 10 and is sleeved on the outer surface of the rotating wheel 11;

[0039] The limiting frame 91 is configured as a U-shaped structure.

[0040] Depend on Figure 3 and Figure 4 It can be seen that the supporting structure 94 includes a support plate 941, a limiting rod 942, a groove 943, a displacement block 944 and a base 945. Two limiting rods 942 are provided, and the two limiting rods 942 are fixedly inserted and connected to the bottom end of the support plate 941. The groove 943 is opened on the top side of the support plate 941. A cushion is arranged in the groove 943 to improve the comfort. The displacement block 944 is fixedly connected to one end of the support plate 941, and the base 945 is fixedly connected to the bottom end of the displacement block 944. The base 945 is connected to the screw 96 bearing together, so that the screw 96 will not drive the base 945 to rotate when it rotates.

[0041] As can be seen from the above, the screw 96 is rotated according to the needs of the user, the output end of the screw 96 moves upward, and pushes the base 945 connected to its bearing to move, the base 945 drives the displacement block 944 fixedly connected to it to move, the displacement block 944 drives the support plate 941 fixedly connected to it to move, so that the support plate 941 supports the user's lower jaw to move upward, thereby better supporting the user's head.

[0042] Preferably, the two limiting rods 942 are movably connected to the limiting frame 91 .

[0043] As can be seen from the above, the limiting rod 942 and the limiting frame 91 are movably interlaced together, so that the supporting plate 941 can be limited, thereby improving the stability of the lifting and lowering of the supporting plate 941.

[0044] Embodiment 2:

[0045] refer to Figure 5As shown, the positioning structure 92 includes a back neck pad 921, an arc plate 922, a moving rod 923 and a positioning rod 925. There are two arc plates 922, two moving rods 923 and two positioning rods 925, and the two arc plates 922 are respectively fixedly connected to the two ends of the back neck pad 921, and the moving rods 923 are respectively fixedly connected to the ends of the two arc plates 922 away from the back neck pad 921. A plurality of positioning holes 924 are evenly spaced at the top of the moving rod 923. The two positioning rods 925 are respectively movably inserted and connected in the positioning holes 924 on both sides, so that the moving rods 923 can be adjusted by using the positioning rods 925. For positioning, the moving rods 923 are movably connected and inserted in the limit frame 91. The design of the back neck pad 921 fully considers the principles of ergonomics. The upper and lower parts of the back neck pad 921 adopt an arc structure. This design aims to perfectly fit the user's back neck curve and provide stable and comfortable limit support. Furthermore, in order to enhance the comfort of use, the part of the back neck pad 921 that is in direct contact with the user's skin is specially equipped with a soft and comfortable cushion material. This cushion is not only soft to the touch, but also can effectively relieve the sense of oppression that may be caused by long-term use, thereby comprehensively improving the user's overall comfort experience.

[0046] As can be seen from the above, the moving rod 923 is inserted into the limiting frame 91 to push the back neck pad 921, and the back neck pad 921 drives the moving rod 923 fixedly connected thereto to slide in the limiting frame 91, so that the back neck pad 921 fits the back neck of the user, and then the positioning rod 925 passes through the limiting frame 91 and is inserted into the corresponding positioning hole 924, so as to fix the moving rod 923 and protect the neck of the user.

[0047] Preferably, the two positioning rods 925 both pass through the top of the limiting frame 91 and are movably connected with the corresponding positioning holes 924 .

[0048] As can be seen from the above, by setting the positioning rod 925 and the positioning hole 924, the movable rod 923 can be positioned, which not only enables the movable rod 923 to be firmly locked after being adjusted to a suitable position to prevent it from accidentally moving during subsequent use, but also greatly improves the stability and reliability of the entire structure, ensuring that users can enjoy the best experience during use.

[0049] Embodiment three:

[0050] refer to Figure 6As shown, the adjustment structure 5 includes a movable frame 51, a connecting groove 52, a positioning column 53 and a second limiting wheel 54. The connecting groove 52 is opened on one side of the top of the movable frame 51, the positioning column 53 is movably inserted and connected in the connecting groove 52, and the second limiting wheel 54 is movably inserted and connected on the inner side of the movable frame 51. By setting the second limiting wheel 54, the traction rope 8 can be effectively supported to ensure its stability during operation. Specifically, we movably insert and connect the second limiting wheel 54 with the movable frame 51. Such a design enables the second limiting wheel 54 to rotate smoothly when the traction rope 8 moves. This rotation action not only significantly reduces the friction resistance between the traction rope 8 and the surrounding structure, but also greatly improves the flexibility, which helps to reduce the wear of the traction rope 8, thereby effectively extending its service life and ensuring the long-term stable operation of the entire traction system. The movable frame 51 is in close contact with the top of the fixed frame 4.

[0051] As can be seen from the above, the movable frame 51 is pulled as needed, the movable frame 51 slides on the top of the fixed frame 4, and drives the second limiting wheel 54 movably connected thereto to move, and the second limiting wheel 54 fine-adjusts the position of the fixed structure 9 through the traction rope 8. After determining the position of the fixed structure 9, the positioning column 53 is twisted to fix the movable frame 51, so that it can be fine-tuned according to the needs of the user.

[0052] Preferably, the bottom end of the positioning column 53 passes through the connecting groove 52 and is threadedly connected to the fixing frame 4 .

[0053] As can be seen from the above, the positioning column 53 is threadedly connected to the fixing frame 4, so that the movable frame 51 can be fixed by twisting the positioning column 53, which is easy to operate and ensures that the movable frame 51 can be firmly locked in the required position, thereby providing stable support and accurate positioning.

[0054] Furthermore, the present invention is designed and applied in cervical vertebra care. When the user needs cervical vertebra care, the user sits on the top of the base 1 and pulls the movable frame 51 according to personal needs. The movable frame 51 slides on the top of the fixed frame 4 and drives the second limiting wheel 54 to move. Through the transmission of the traction rope 8, the position of the fixed structure 9 can be fine-tuned. Once the appropriate position of the fixed structure 9 is determined, the positioning column 53 is turned to firmly fix the movable frame 51, thereby achieving precise adjustment according to the user's personalized needs.

[0055] Next, the user places the neck in the limiting frame 91 and inserts the moving rod 923 into the limiting frame 91. By gently pushing the back neck pad 921, the back neck pad 921 moves and drives the moving rod 923 to slide smoothly in the limiting frame 91 until the back neck pad 921 perfectly fits the back of the user's neck. Subsequently, the positioning rod 925 is passed through the limiting frame 91 and tightly inserted into the corresponding positioning hole 924, thereby firmly fixing the moving rod 923 to prevent accidental sliding during use, and also providing thoughtful protection and stable support for the user's neck, ensuring peace of mind and comfort throughout the entire use process.

[0056] When the user's lower jaw is close to the bottom groove wall of the groove 943, the screw 96 can be rotated according to actual needs. As the output end of the screw 96 slowly rises, it will push the base 945 to move, and the base 945 will drive the displacement block 944 closely connected to it to move, and then drive the support plate 941 fixed on the displacement block 944 to move. In this way, the support plate 941 can effectively support the user's lower jaw and move it slowly upward, thereby providing a more stable and comfortable support for the head. It is worth noting that during the entire process of the displacement of the support plate 941, the limit rod 942 always maintains a smooth sliding in the limit frame 91. This design not only ensures the accuracy of the displacement of the support plate 941, but also further enhances its displacement stability, bringing users a more secure and reliable use experience.

[0057] Finally, the driver 12 is started, and its output end begins to rotate, driving the rotating wheel 11 to rotate synchronously. The rotating wheel 11 begins to reel in the traction rope 8, and the traction rope 8 moves smoothly on the outer surfaces of the first limiting wheel 7 and the second limiting wheel 54, while driving the first limiting wheel 7 and the second limiting wheel 54 to rotate. As the traction rope 8 continues to move, the fixed structure 9 will also slowly rise, thereby gently tractioning the user's neck. During this traction process, not only the muscles around the user's spine are effectively relaxed, but also the intervertebral pressure is significantly relieved, bringing a soothing and comfortable use experience to the user.
