DETAILED DESCRIPTION
[0022] The following is combined with Figure 1-3 , the technical solution of the utility model is further explained:
[0023] like Figure 1-Figure 3As shown, a cervical vertebra rehabilitation traction frame includes two uprights 1 with a support rod 2 positioned between them. Each of the two uprights 1 is provided with a connecting sleeve 3 for mounting at the foot and / or head of a bed. Specifically, a support rod is positioned between the two uprights, with a lifting ring mounted on the support rod. Connecting sleeves are mounted on each of the two uprights. The position of the connecting sleeves on the uprights is adjusted according to the height of the bed. Once the appropriate position is selected, the connecting sleeves are secured to the uprights and then secured to the bed's steel pipes.
[0024] Specifically, if Figure 1 As shown, the support rod 2 comprises two sleeve rod sections and a connecting rod section, with the ends of the connecting rod respectively inserted into the two sleeve rod sections, and the connecting rod and the sleeve rod are detachably connected. In other words, the support rod as a whole is composed of three parts, with the ends of the connecting rod respectively inserted into the sleeve rod, and the length of the connecting rod within the sleeve rod can be adjusted according to the width of the bed.
[0025] In some embodiments, as Figure 1 As shown, the connecting rod and the sleeve rod are each provided with a second connecting hole. The corresponding second connecting holes are connected by bolts, so that the insertion length of the connecting rod into the sleeve rod can be adjusted according to the width of the bed. In other words, the insertion length of the connecting rod into the sleeve rod is adjusted according to the width of the bed. After the adjustment is to the appropriate position, the connecting rod and the sleeve rod are fixed by bolts passing through the corresponding second connecting holes.
[0026] Specifically, if Figure 1 As shown, a sleeve is provided on one side of each sleeve rod, which is sleeved onto the vertical rod. A first connection hole is provided on each sleeve and the vertical rod, and the corresponding first connection holes are connected by bolts to adjust the position of the sleeve on the vertical rod according to the height of the bed. In other words, the position of the sleeve on the vertical rod is adjusted according to the height of the bed. When the sleeve is adjusted to the appropriate height, the sleeve is fixed to the vertical rod by screwing a bolt into the first connection hole, thereby fixing the support rod to the vertical rod.
[0027] Specifically, if Figure 1 As shown, the connecting sleeve 3 includes a vertical positioning sleeve and a first clamping plate. The vertical positioning sleeve is connected to the first clamping plate and is mounted on the vertical rod. The first clamping plate and the second clamping plate are detachably connected for securing the vertical rod to the bed. In other words, the vertical positioning sleeve is in the form of a sleeve, which is mounted on the vertical rod. The position of the sleeve on the vertical rod is adjusted according to the height of the steel pipe on the bed. Once the sleeve is in place, it is fixed. The first and second clamping plates are then wrapped around the steel pipe, and the bolts are tightened to secure the vertical rod to the bed.
[0028] In some embodiments, the vertical positioning sleeve has a through hole corresponding to the first connection hole on the upright post. The through hole is connected to the first connection hole via a bolt, allowing the vertical positioning sleeve to be adjusted on the upright post according to the height of the bed. In other words, the vertical connection sleeve is adjusted on the upright post according to the height of the bed. Once the adjustment is appropriate, the bolt is tightened to secure the position.
[0029] Specifically, if Figure 1 As shown, the support rod 2 is provided with a lifting ring 4, and the lifting ring 4 is provided with an adjustment mechanism. The adjustment mechanism is connected to the suspension mechanism, and a cervical traction belt 8 is suspended on the suspension mechanism. The adjustment mechanism drives the suspension mechanism to move up and down to adjust the height of the cervical traction belt. In other words, the adjustment mechanism provided in the lifting ring can drive the suspension mechanism to move through the adjustment mechanism, and the suspension mechanism can synchronously drive the cervical traction belt to move.
[0030] Specifically, if Figure 1 As shown, the adjustment mechanism includes a rope reel 5 and a ratchet 6. A cavity structure for accommodating the rope reel 5 and the ratchet 6 is provided at the bottom of the suspension ring 4. The rope reel 5 is movably arranged in the cavity structure via a movable shaft. A rope is wound around the rope reel 5, and an opening for the rope to pass through is provided at the bottom of the suspension ring 4. One end of the rope passing through is connected to the suspension mechanism. In other words, the rope reel and the ratchet are installed in the cavity within the suspension ring. The rope reel and the ratchet rotate coaxially, that is, the rope reel and the ratchet rotate synchronously. At the same time, a rope is wound around the rope reel, and the rope passes through the cavity and is connected to the suspension mechanism.
[0031] A limit lock handle 12 is provided within the cavity structure. One end of the limit lock handle 12 is movably disposed within the cavity structure. The other end of the limit lock handle 12 is provided with a limit tooth. A torsion spring 13 is provided on the limit lock handle 12. One end of the torsion spring 13 abuts against the limit lock handle 12, and the other end of the torsion spring 13 abuts against the inner wall of the lifting ring 4. The limit tooth engages with the ratchet 6 to maintain unidirectional rotation of the rope winding wheel when the limit lock handle is in the limited state. In other words, the ratchet and the lock tooth on the limit lock handle are engaged. When the ratchet rotates clockwise, the ratchet shifts the lock tooth, allowing the ratchet to maintain clockwise rotation. When the ratchet rotates counterclockwise, the ratchet and the lock tooth remain tightly engaged, preventing the ratchet from rotating counterclockwise and allowing only unidirectional rotation. At the same time, when the ratchet rotates clockwise to shift the lock tooth to lift, the lock tooth quickly returns to engage the ratchet under the action of the torsion spring, ensuring smooth rotation of the rope winding wheel.
[0032] In some embodiments, as Figure 2As shown, the rope reel 5 is provided with a first connecting handle 10 extending outward through the lifting ring. The first connecting handle 10 is provided on the turntable 9. The turntable 9 is movably buckled on a limiting boss provided on one side of the lifting ring 4. The turntable 9 is connected to the movable shaft. The first connecting handle 10 is provided with a first pulling hand rope 11. By pulling the first pulling hand rope 11, the rope reel 5 is driven to rotate unidirectionally under the limit of the limiting lock handle 12. In other words, a circular limiting boss is provided on one side of the lifting ring, and turntables are nested on the limiting bosses. The turntables can rotate on the limiting bosses, and then the first connecting handle and the turntable can be driven to rotate synchronously by pulling the first pulling hand rope. The first connecting handle drives the rope reel to rotate and reel in the rope, thereby driving the suspension mechanism to rise.
[0033] In some embodiments, as Figure 3 As shown, the limit lock handle 12 is provided with a second connecting handle extending outward through the lifting ring. The other side of the lifting ring 4 is provided with an arc-shaped channel for the movement of the second connecting handle. The second connecting handle is provided with a second pulling hand rope. By pulling the second pulling hand rope, the lock teeth on the limit lock handle are disengaged from the ratchet wheel, thereby releasing the one-way rotation state of the rope winding wheel. In other words, the limit lock handle is provided with a second connecting handle extending outward. By pulling the second connecting handle, the limit lock handle is lifted, thereby disengaging the lock teeth from the ratchet wheel.
[0034] Specifically, the suspension mechanism includes a Y-shaped suspension frame 7, the top of which is connected to the rope on the rope reel 5, and hooks are provided at both ends of the suspension frame 7, and the hanging rings on both sides of the cervical traction belt 8 are respectively mounted on the hooks. In other words, the Y-shaped suspension frame is used as a structural support for suspending the cervical traction belt.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
