[0002] Auxiliary support devices for orthopedic rehabilitation play a vital role in the patient's rehabilitation process. These devices are designed to reduce the dysfunction of the limbs, spine and musculoskeletal system, and provide patients with necessary support, fixation and protection. Crutch is another common auxiliary support device for orthopedic rehabilitation. It can reduce the weight of the patient's lower limbs, or assist patients who cannot bear weight on their lower limbs due to various reasons to stand or walk.

[0003] The existing auxiliary support devices for orthopedic rehabilitation have the following problems:

[0004] The existing auxiliary support devices for orthopedic rehabilitation have poor stability when used by patients with weak arm strength, which increases the chance of patients falling, thereby prolonging the patients' recovery time. In addition, when the traditional auxiliary support devices for orthopedic rehabilitation are used for a long time for rehabilitation, the impact force generated by the auxiliary support devices and the ground will compress the patient's armpits, thereby causing compression injury to the patient's lower brachial plexus nerve, thereby reducing the use efficiency of the auxiliary support devices. Therefore, it cannot meet the existing use needs of auxiliary support devices. Summary of the invention

[0006] The present invention proposes an auxiliary support device for orthopedic rehabilitation, including a rotating block, a connecting bolt, a double-support type auxiliary mechanism, a vibration-absorbing type training mechanism and a ground-contacting type sliding mechanism. The connecting bolts are symmetrically arranged on both sides of the rotating block, the double-support type auxiliary mechanism is arranged at one end of the connecting bolt away from the rotating block, the vibration-absorbing type training mechanism is arranged on the double-support type auxiliary mechanism, the ground-contacting type sliding mechanism is arranged at one end of the double-support type auxiliary mechanism away from the vibration-absorbing type training mechanism, the double-support type auxiliary mechanism includes a lower body mechanism and an upper body mechanism, and the lower body mechanism The structure is arranged at the end of the connecting bolt away from the rotating block, the upper body mechanism is arranged on the upper wall of the lower body mechanism, the vibration-absorbing type training mechanism includes a dynamic support mechanism and a lifting mechanism, the dynamic support mechanism is arranged on the upper body mechanism, and the lifting mechanism is arranged on the dynamic support mechanism.

[0008] When in use, the rotating block is rotated, and the rotating block drives the connecting bolt to rotate. The connecting bolt is screwed out from the threaded hole, and the transfer blocks on both sides of the rotating block are detached from the outside of the connecting bolt. Patients with leg fractures need to use crutches for rehabilitation. The patients hold the lifting rod with their hands and use the supporting force of the support column for assisted rehabilitation.

[0009] Preferably, the dynamic support mechanism includes a guide opening, a sliding groove, a sliding plate and a shock-absorbing spring, the guide opening is arranged inside the guide column, the sliding groove is arranged on the inner wall of one end of the guide column close to the transfer block, the sliding groove is a through arrangement, the sliding plate passes through the sliding groove and slides between the guide opening, and the shock-absorbing spring is arranged between the sliding plate and the transfer block; the lifting mechanism includes a U-shaped lifting frame and a padded column, the U-shaped lifting frame passes through the guide opening and is arranged on the upper wall of the sliding plate, and the padded column is arranged at one end of the U-shaped lifting frame away from the sliding plate.

[0010] When in use, in the initial state, the shock-absorbing spring is in an extended setting, the armpit of the patient with a leg fracture contacts the cushion column, the arm and the side wall of the patient with a leg fracture clamp the cushion column, the center of gravity of the patient with a leg fracture falls on the cushion column, the cushion column pushes the sliding plate through the U-shaped lifting frame, the sliding plate slides along the sliding groove to press down the shock-absorbing spring, and the shock-absorbing spring supports the patient with a leg fracture through elastic deformation force. When walking, the patient with a leg fracture first lifts the U-shaped lifting frame and the cushion column clamped by one side of the body and moves forward. At this time, the shoulder of the patient with a leg fracture changes from a horizontal state to an inclined state, and the shock-absorbing spring The deformation and elongation pushes the U-shaped lifting frame to slide along the guide opening through the sliding plate. The sliding of the U-shaped lifting frame drives the soft cushion column to always fit the armpit of the patient with a leg fracture. When the patient with a leg fracture lifts and lowers the support column through the lifting rod, the support column hits the ground, and the shock-absorbing spring offsets the vibration force generated by the support column hitting the ground through the deformation force generated, thereby avoiding the vibration force from compressing the armpit of the patient with a leg fracture, so as to avoid compression injury of the lower brachial plexus nerve, thereby ensuring that the patient with a leg fracture can perform long-term rehabilitation exercises without damaging the armpit, which can accelerate the rehabilitation progress of the patient with a leg fracture.

[0011] Specifically, the angle mechanism includes a hinge block, a positioning plate, an arc groove and an angle rod, the hinge block is arranged on a side of the support column away from the transfer block, the positioning plate is rotatably arranged at one end of the hinge block away from the support column, the arc groove is symmetrically arranged on both sides of the hinge block, the arc groove is a through arrangement, the angle rod is symmetrically arranged at one end of the positioning plate close to the hinge block, and the end of the angle rod away from the positioning plate is arranged inside the arc groove; the heavy sliding mechanism includes a ground frame, a weight-increasing plate and a wear-resistant slide plate, the ground frame is symmetrically arranged at both ends of the positioning plate, the ground frame is rotatably connected to the positioning plate, the weight-increasing plate is penetrated through the inner wall of the end of the ground frame away from the positioning plate, and the wear-resistant slide plate is arranged on the bottom wall of the weight-increasing plate; the limiting mechanism includes a limiting mouth, a sliding limit spring and a positioning cone, the limiting mouth is arranged on the bottom wall of the positioning plate, the positioning cone is slidably arranged inside the limiting mouth, and the sliding limit spring is arranged between the positioning cone and the inner wall at the top of the limiting mouth.

[0012] When in use, in order to prevent patients with leg fractures from lifting the support column too high during rehabilitation exercises, which increases the impact force between the support column and the ground, increases the vibration force on the patient with leg fractures, and causes damage to the patient's armpits, the wear-resistant slide plate is in contact with the ground, and the limited slip spring is in an extended setting. The limited slip spring pushes the positioning cone to fit the ground. At this time, the wear-resistant slide plate and the ground are in a relatively fixed state to ensure that the wear-resistant slide plate does not actively slide. The circumferential range of movement of the support column is consistent with the circumferential length range of the arc groove, and the positioning plate is horizontally arranged with the ground frame. When the patient with leg fracture lifts the support column, the positioning plate rotates along the ground frame, and the positioning plate drives the positioning cone away from the ground, and the wear-resistant slide plate is in a relatively fixed state. It changes to an active state, and the wear-resistant slide plate is always in contact with the ground under the support of the gravity of the weight-increasing plate. On the one hand, it can limit the lifting height of the support column and reduce the impact force between the support column and the ground. On the other hand, it can ensure the stability of the support column during the assisted rehabilitation process and reduce the chance of the support column tipping over. When the support column moves forward, it pushes the ground frame through the positioning plate, and the ground frame drives the wear-resistant slide plate to slide forward along the ground through the weight-increasing plate. Then the shoulder of the patient with a leg fracture falls down, and the center of gravity of the patient with a leg fracture falls back on the support column. The support column presses down the positioning plate, and the positioning plate rotates and descends. The positioning plate drives the positioning cone to fit with the ground, and the wear-resistant slide plate is relatively fixed, thereby completing the auxiliary operation for the patient's rehabilitation.

[0013] The beneficial effects achieved by adopting the above structure are as follows:

[0014] Compared with the prior art, the present invention adopts a combination of a limiting structure and a vibration reduction structure, and through the provision of a double-support auxiliary mechanism, a vibration-absorbing training mechanism and a ground-contacting sliding mechanism, the lower body mechanism, the upper body mechanism, the dynamic support mechanism, the lifting mechanism, the angle mechanism, the heavy sliding mechanism and the limiting mechanism cooperate with each other, and the sliding performance of the wear-resistant slide plate is utilized to slide along the ground. With the intervention of the weight-increasing plate, the lifting height of the support column is limited, and the impact force of the support column on the ground is reduced, so as to avoid damage to the patient's armpits under the action of long-term vibration force, ensure the stability of the patient's rehabilitation exercises, accelerate the patient's rehabilitation progress, and improve The utilization efficiency of the rehabilitation auxiliary structure, the wear-resistant slide plate is in contact with the ground, the limited slip spring is in an extended setting, the limited slip spring pushes the positioning cone to fit the ground, at this time, the wear-resistant slide plate and the ground are in a relatively fixed state, ensuring that the wear-resistant slide plate will not slide actively, the circumferential activity range of the support column is consistent with the circumferential length range of the arc groove, the positioning plate and the ground frame are horizontally arranged, when the patient with a leg fracture lifts the support column, the support column drives the positioning plate to rotate along the ground frame, the positioning plate drives the positioning cone away from the ground, and the wear-resistant slide plate changes from a relatively fixed state to an active state, and the wear-resistant slide plate is always in contact with the ground under the gravity of the weight-increasing plate.

[0033] When in use, the rotating block 1 is manually rotated, and the rotating block 1 drives the connecting bolt 2 to rotate, and the connecting bolt 2 is screwed out from the inside of the threaded hole 6, and the transfer blocks 5 on both sides of the rotating block 1 are detached from the outside of the connecting bolt 2. The patient who is recovering from a leg fracture needs to use a crutch, and the patient holds the lifting rod 10 with his hand, and performs auxiliary rehabilitation exercises with the support force of the support column 7;

[0034] In the initial state, the damping spring 16 is in an extended setting, the armpit of the patient with a leg fracture contacts the cushion column 19, and the arm and body side wall of the patient with a leg fracture clamp the cushion column 19. In order to prevent the patient with a leg fracture from lifting the support column 7 too high during rehabilitation exercises, the distance of the support column 7 from the ground is increased, so that the impact force of the support column 7 falling and the ground is enhanced, and the vibration force on the patient with a leg fracture is increased, resulting in damage to the patient's armpit. The wear-resistant slide plate 29 is in contact with the ground, and the limited slip spring 32 is in an extended setting. The limited slip spring 32 pushes the positioning cone 33 to fit the ground. The wear-resistant slide plate 29 and the ground are in a relatively fixed state, ensuring that the wear-resistant slide plate 29 will not slide actively. The circumferential range of the support column 7 is consistent with the circumferential length range of the arc groove 24, and the positioning plate 23 and the ground frame 27 are set horizontally;

[0035] The body weight of the patient with a leg fracture falls on the cushion column 19, and the cushion column 19 pushes the sliding plate 15 through the U-shaped lifting frame 18. The sliding plate 15 slides along the sliding groove 14 and presses down the shock-absorbing spring 16. The shock-absorbing spring 16 supports the patient with a leg fracture through elastic deformation force. When the patient with a leg fracture walks, he first lifts the U-shaped lifting frame 18 and the cushion column 19 clamped by one side of his body and moves forward. At this time, the shoulder of the patient with a leg fracture changes from a horizontal state to an inclined state. The shock-absorbing spring 16 on the side lifted and moved forward is deformed and elongated, and pushes the U-shaped lifting frame 18 to slide along the guide opening 13 through the sliding plate 15. The sliding of the U-shaped lifting frame 18 drives the cushion column 19 to always fit the armpit of the patient with a leg fracture.

[0036] When the patient with a leg fracture lifts the support column 7, the positioning plate 23 rotates and bulges along the ground frame 27, and the positioning plate 23 drives the positioning cone 33 away from the ground, and the wear-resistant slide plate 29 changes from a relatively fixed state to an active state. The wear-resistant slide plate 29 is always in contact with the ground under the gravity of the weight-added plate 28. On the one hand, it can limit the lifting height of the support column 7 and reduce the impact force between the support column 7 and the ground. On the other hand, it can ensure the stability of the support column 7 during the auxiliary rehabilitation process and reduce the probability of the support column 7 tipping over. When the support column 7 is pushed forward, the ground frame 27 is pushed by the positioning plate 23, and the ground frame 27 drives the wear-resistant slide plate 29 to slide forward along the ground through the weight-added plate 28. The support column 7 drives the positioning plate 23 to fall, and the shoulders of the patient with a leg fracture are reset to the horizontal level. The center of gravity of the patient with a leg fracture falls back on the support column 7, and the support column 7 presses down the positioning plate 23, and the positioning plate 23 rotates and descends, and the positioning plate 23 drives the positioning cone 33 to fit with the ground, so that the wear-resistant slide plate 29 is relatively fixed.

[0037] When the patient with a leg fracture lifts and lowers the support column 7 through the lifting rod 10, the support column 7 hits the ground, and the shock-absorbing spring 16 offsets the vibration force generated by the support column 7 hitting the ground through the deformation force generated, thereby preventing the vibration force from compressing the armpit of the patient with a leg fracture, thereby preventing compression injury to the lower brachial plexus nerve. This can ensure that the patient with a leg fracture can perform long-term rehabilitation exercises without damaging the armpit, thereby accelerating the rehabilitation progress of the patient with a leg fracture, and completing the rehabilitation auxiliary work for the patient with a leg fracture; the above operation can be repeated the next time it is used.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0039] The above is a description of the present solution and its implementation methods, which is not restrictive. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the creative purpose of the present solution, they should all fall within the protection scope of the present solution.
