[0023] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods:

[0024] like Figure 1-5As shown, the utility model provides a medical bed neck traction auxiliary rehabilitation mechanism, including a bed board 1, a mounting frame 2 is sleeved on the top of the bed board 1, a mounting plate 3 is fixedly installed on the top of the mounting frame 2, a traction mechanism 4 and a massage mechanism 5 are arranged on the top of the mounting plate 3, the traction mechanism 4 includes a fixing frame 401, a hanging ring 402 and a head bracket 403, when the head bracket 403 is squeezed, the hanging ring 402 limits the head bracket 403 through the fixing frame 401, so that the head bracket 403 is in a squeezed state, the massage mechanism 5 includes a motor 501, a rotating shaft 502, a driven shaft 503, a cam 504 and a cloth 505, when the output end of the motor 501 rotates, the rotating shaft 502 and the driven shaft 503 are driven to rotate, and after the rotating shaft 502 and the driven shaft 503 rotate, a plurality of cams 504 are driven to rotate, and when the plurality of cams 504 rotate, the cloth 505 can be cyclically squeezed.

[0025] When the patient needs to undergo a rehabilitation treatment for the neck, the patient first sits on the mattress 6, then leans his back against the fabric 505, and then places his chin on the head bracket 403. At this time, the patient squeezes the head bracket 403. Under the limiting effect of the fixing frame 401 and the hanging ring 402, the head bracket 403 can be squeezed by the patient, and then a force is applied to the patient, so that a certain effect can be exerted on the patient's neck to achieve a correction effect;

[0026] When the patient's neck is being rehabilitated, the motor 501 is started, and the output end of the motor 501 rotates to drive the rotating shaft 502 to rotate. When the rotating shaft 502 rotates, it drives the cams 504 to rotate, and drives the main gear 508 to rotate. When the cams 504 rotate, they can rotate clockwise and continuously squeeze the cloth 505. Since the patient's back is closely attached to the cloth 505, the cams 504 squeeze the patient's back through the cloth 505 at this time, and then during the patient's neck rehabilitation process, the patient's back muscles can be relieved, so that the patient will not experience muscle soreness too early when sitting for a long time, thereby improving the rehabilitation effect on the neck;

[0027] When the rotating shaft 502 rotates, it can drive the driven shaft 503 to rotate relatively inversely. When the driven shaft 503 rotates, it drives another group of cams 504 to rotate. Since the driven shaft 503 and the rotating shaft 502 are in a relatively reverse state at this time, the two groups of cams 504 are in a relatively reverse state at this time, so that the two groups of cams 504 can use two different directions of squeezing effects when rotating, effectively stimulating the patient's muscles, thereby improving the massage effect, extending the time of a single course of neck rehabilitation work, and improving the rehabilitation efficiency;

[0028] The head support 403 and the cloth 505 are both prior art and will not be explained here.

[0029] In one embodiment, the massage mechanism 5 further includes a protective shell 506 , which is fixedly connected to the top of the mounting plate 3 , and the fabric 505 is mounted on one side of the protective shell 506 and is limited by the protective shell 506 .

[0030] The protective shell 506 can limit the position of the fabric 505 to prevent the fabric 505 from being damaged when being squeezed. At the same time, the protective shell 506 can prevent the structure from being directly exposed to the outside, thereby reducing the probability of parts being damaged and extending the service life.

[0031] In one embodiment, the massage mechanism 5 also includes a transmission shaft 507, a main gear 508, a sub-gear 509 and a belt 510. When the output end of the motor 501 rotates, the transmission shaft 507 is driven to rotate through the main gear 508 and the sub-gear 509. When the transmission shaft 507 rotates, it is reversed relative to the rotating shaft 502. At the same time, the driven shaft 503 is driven to rotate through the belt 510, so that the rotating shaft 502 and the driven shaft 503 are reversed relative to each other, so that the two sets of cams 504 can apply forces in different directions to the fabric 505.

[0032] When the rotating shaft 502 rotates, it drives several cams 504 to rotate, and drives the main gear 508 to rotate. When the main gear 508 rotates, the main gear 508 can drive the sub-gear 509 to rotate by meshing with the sub-gear 509. At this time, the sub-gear 509 rotates in the opposite direction to the main gear 508. After the sub-gear 509 rotates, it drives the transmission shaft 507 to rotate. After the transmission shaft 507 rotates, it drives the driven shaft 503 to rotate through the belt 510. When the driven shaft 503 rotates, it drives another group of cams 504 to rotate. Since the driven shaft 503 and the rotating shaft 502 are in a relatively reverse state at this time, the two groups of cams 504 are in a relatively reverse state at this time, so that the two groups of cams 504 can adopt two different directions of squeezing effects when rotating, which effectively stimulates the patient's muscles, thereby improving the massage effect, extending the time of a single course of neck rehabilitation work, and improving rehabilitation efficiency.

[0033] In one embodiment, the mounting end of the motor 501 is fixedly connected to the inner wall of the protective shell 506, the rotating shaft 502, the driven shaft 503 and the transmission shaft 507 are all rotatably connected to the protective shell 506, one end of the rotating shaft 502 is fixedly connected to the output end of the motor 501, the main gear 508 is fixedly sleeved on the rotating shaft 502, the sub-gear 509 is fixedly sleeved on the transmission shaft 507 and meshes with the main gear 508, and the belt 510 is sleeved on the driven shaft 503 and the transmission shaft 507.

[0034] By installing the motor 501 inside the protective shell 506, direct contact between the patient and the motor 501 can be avoided, the probability of patient injury is reduced, and the structure is rationalized.

[0035] In one embodiment, the traction mechanism 4 also includes a support frame 404, a connecting rod 405 and a cylinder 406. The support frame 404 is fixedly connected to the top of the mounting plate 3, and the two ends of the connecting rod 405 are respectively fixedly connected to the cylinder 406 and the support frame 404. The output end of the cylinder 406 is fixedly connected to the top of the fixing frame 401, and the hanging ring 402 is connected to the fixing frame 401 and the head bracket 403.

[0036] The support frame 404 and the connecting rod 405 are connected to the fixed frame 401 through the cylinder 406. When the output end of the cylinder 406 is extended, the cylinder 406 drives the head bracket 403 to move vertically through the fixed frame 401 and the hanging ring 402, and drives the patient's head to move, so that the patient's neck is stressed and rehabilitation work is achieved.

[0037] In one embodiment, a plurality of insertion rods are installed on the top of the bed board 1, and mattresses 6 are installed on the plurality of insertion rods.

[0038] The mattress 6 is a sponge pad, which is used to relieve the patient's hip muscles;

[0039] Sponge pads are prior art and will not be explained here.

[0040] In one embodiment, a bed frame 101 is fixedly mounted on the bottom of the bed board 1 .

[0041] The bed frame 101 is used to support the bed board 1, increase the height of the bed board 1, and facilitate the patient's activities.

[0042] The following is a detailed description of the working principle of the cervical traction assisted rehabilitation mechanism of the medical bed;

[0043] When the patient needs to undergo a rehabilitation treatment for the neck, the patient first sits on the mattress 6, then leans his back against the fabric 505, and then places his chin on the head bracket 403. At this time, the patient squeezes the head bracket 403. Under the limiting effect of the fixing frame 401 and the hanging ring 402, the head bracket 403 can be squeezed by the patient, and then a force is applied to the patient, so that a certain effect can be exerted on the patient's neck to achieve a correction effect;

[0044] When the patient's neck is being rehabilitated, the motor 501 is started, and the output end of the motor 501 rotates to drive the rotating shaft 502 to rotate. When the rotating shaft 502 rotates, it drives the cams 504 to rotate, and drives the main gear 508 to rotate. When the cams 504 rotate, they can rotate clockwise and continuously squeeze the cloth 505. Since the patient's back is closely attached to the cloth 505, the cams 504 squeeze the patient's back through the cloth 505 at this time, and then during the patient's neck rehabilitation process, the patient's back muscles can be relieved, so that the patient will not experience muscle soreness too early when sitting for a long time, thereby improving the rehabilitation effect on the neck;

[0045] When the main gear 508 rotates, the main gear 508 can drive the secondary gear 509 to rotate by meshing with the secondary gear 509. At this time, the secondary gear 509 rotates in the opposite direction to the main gear 508. After the secondary gear 509 rotates, it drives the transmission shaft 507 to rotate. After the transmission shaft 507 rotates, it drives the driven shaft 503 to rotate through the belt 510. When the driven shaft 503 rotates, it drives another group of cams 504 to rotate. Since the driven shaft 503 and the rotating shaft 502 are in a relative reversal state at this time, the two groups of cams 504 are in a relative reversal state at this time, so that the two groups of cams 504 can adopt two different directions of squeezing effects when rotating, which effectively stimulates the patient's muscles, thereby improving the massage effect, extending the time of a single course of neck rehabilitation work, and improving rehabilitation efficiency.

[0046] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
