Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a walking aid device for postoperative rehabilitation exercises. Background Technology

[0002] A walking aid is a walking support tool designed for elderly people with mobility issues, those who are physically weak after surgery, or people with disabilities to help them walk or exercise their limbs. Walking aids can help post-operative patients improve their rehabilitation efficiency through long-term walking exercises, allowing them to walk slowly and easily while holding onto the device.

[0003] For example, the utility model disclosed in patent application CN219230602U provides a rehabilitation walking aid that protects the patient within a three-sided frame and allows for rest by a seat. However, this prior art still has the following problems in use:

[0004] The rehabilitation walker is equipped with a pair of rollers and a non-slip mat at the bottom. On rough ground, the device needs to lift one side of the non-slip mat to move forward. When the front of the rollers comes into contact with an obstacle, the patient can push the lever, which may cause the support frame to flip forward, resulting in the patient falling. Utility Model Content

[0005] The purpose of this invention is to provide a walking aid for postoperative rehabilitation exercises, which solves the problem in the prior art where, when the front of the rollers comes into contact with an obstacle, the patient pushing the push rod can easily cause the support frame to flip forward, resulting in the patient falling.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] A walking aid for postoperative rehabilitation exercises, comprising:

[0008] The mounting frame includes a first connecting rod, a mounting rod, a vertical rod, an arc-shaped rod, a reinforcing rod, a fixed shaft, and a second connecting rod.

[0009] The second roller is installed at the bottom of the mounting bracket, and the second roller can improve the stability of the movement of the mounting bracket;

[0010] A seat mechanism is provided on the top of the mounting frame. The seat mechanism can be flipped downwards to facilitate limiting the position of the mounting frame.

[0011] In a preferred embodiment, symmetrical mounting rods are fixedly provided at the left and right ends of the first connecting rod, a vertical rod is fixedly provided at the top of the mounting rod, an arc-shaped rod is fixedly provided at the top of the vertical rod, a reinforcing rod is fixedly provided on the outside of the vertical rod, the other end of the reinforcing rod is fixedly connected to the arc-shaped rod, and a second connecting rod and a fixed shaft are fixedly provided between the sides of the vertical rod and the reinforcing rod that are close to each other.

[0012] In a preferred embodiment, a first roller is mounted on the front end of the mounting rod, and a second roller is mounted on the other end of the first roller.

[0013] In a preferred embodiment, a rubber anti-slip sleeve is fixedly provided at the end of the arc-shaped rod away from the vertical rod.

[0014] In a preferred embodiment, the seat mechanism includes a fixing ring, a sleeve, a base plate, a seat cushion, a counterweight, and a stop bar. Symmetrical fixing rings are fixedly arranged on the outer side of the fixing shaft, and a sleeve is rotatably connected to the outer side of the fixing shaft. A base plate is fixedly arranged on the outer side of the sleeve, and a seat cushion is fixedly arranged on the side of the base plate. A stop bar is fixedly arranged on the side of the base plate away from the sleeve, and symmetrical counterweights are fixedly arranged at both ends of the stop bar.

[0015] In a preferred embodiment, the inner side of the sleeve is provided with a through groove adapted to the fixed shaft, the fixed shaft passes through the through groove through the sleeve, and the left and right sides of the sleeve are respectively rotatably connected to the fixed ring.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This invention features a mounting frame and a second roller. When the first and second rollers simultaneously contact the ground, the rubber anti-slip sleeve lifts up and detaches from the ground. The patient can push the arc-shaped rod to move the device forward. The first roller, in conjunction with the second roller, improves the stability of the device and prevents it from tipping over significantly when either roller contacts an obstacle, thus reducing the risk of the patient falling. When the first roller and the rubber anti-slip sleeve simultaneously contact the ground, the device can be stopped from moving further, allowing the patient to stop and rest.

[0018] This invention features a seating mechanism that unfolds downwards and contacts an arc-shaped rod, allowing the patient to sit and rest. Rotation of the seating mechanism shifts the device's center of gravity forward, causing the mounting frame to rotate until the rubber anti-slip sleeve contacts the ground. This automatically limits the position of the mounting frame after the seating mechanism is unfolded. When the patient retracts the seating mechanism, the device's center of gravity shifts backward, causing the mounting frame to rotate in the opposite direction until the rubber anti-slip sleeve leaves the ground and the second roller contacts the ground, releasing the limitation on the mounting frame and facilitating rehabilitation exercises for the patient.

[0033] Please see the appendix Figure 1 As shown, this utility model provides a walking aid for postoperative rehabilitation exercises, including: a mounting frame 100, a second roller 3, and a sitting plate mechanism 500.

[0034] In a preferred embodiment, please refer to Figures 1-4The mounting bracket 100 consists of a first connecting rod 101, a mounting rod 102, a vertical rod 103, an arc-shaped rod 104, a reinforcing rod 105, a fixed shaft 106, and a second connecting rod 107. The first connecting rod 101 has symmetrical mounting rods 102 fixedly installed at its left and right ends. The top of the mounting rod 102 has a vertical rod 103 fixedly installed. The top of the vertical rod 103 has an arc-shaped rod 104 fixedly installed. The outside of the vertical rod 103 has a reinforcing rod 105 fixedly installed. The other end of the reinforcing rod 105 is fixedly connected to the arc-shaped rod 104. The second connecting rod 107 and the fixed shaft 106 are fixedly installed between the sides of the vertical rod 103 and the reinforcing rod 105 that are close to each other.

[0035] In a preferred embodiment, please refer to Figures 1-4 The bottom of the mounting bracket 100 is equipped with symmetrical first rollers 2, second rollers 3 and rubber anti-slip sleeves 4. The first rollers 2 and second rollers 3 are respectively installed at the front and rear ends of the mounting rod 102. The end of the arc-shaped rod 104 away from the vertical rod 103 is fixedly connected to the rubber anti-slip sleeve 4. The rubber anti-slip sleeve 4 can limit the position of the mounting bracket 100 when in contact with the ground, so as to prevent the device from shifting when not in use.

[0036] In this embodiment, when the first roller 2 and the second roller 3 simultaneously contact the ground, the rubber anti-slip sleeve 4 lifts up and detaches from the ground. The patient can push the arc-shaped rod 104 to move the device forward. The first roller 2, in conjunction with the second roller 3, can improve the stability of the device and prevent the device from overturning significantly when the first roller 2 or the second roller 3 contacts an obstacle, thus reducing the risk of the patient falling. When the first roller 2 and the rubber anti-slip sleeve 4 simultaneously contact the ground, the device can be prevented from continuing to move. At this time, the second roller 3 lifts up and detaches from the ground, making it convenient for the patient to stop and rest.

[0037] In a preferred embodiment, please refer to Figures 1-4 The mounting bracket 100 has a seat mechanism 500 on its top. The seat mechanism 500 consists of a fixing ring 501, a sleeve 502, a base plate 503, a seat cushion 504, a counterweight 505, and a stop bar 506. Symmetrical fixing rings 501 are fixedly mounted on the outer side of the fixing shaft 106. The sleeve 502 is rotatably connected to the outer side of the fixing shaft 106. A through groove adapted to the fixing shaft 106 is provided on the inner side of the sleeve 502. The fixing shaft 106 passes through the sleeve 502 via the through groove. The left and right sides of the sleeve 502 are rotatably connected to the fixing ring 501 respectively. A base plate 503 is fixedly installed on the outer side of the sleeve 502. A cushion 504 is fixedly installed on the side of the base plate 503. The cushion 504 can improve the comfort of the patient sitting on the base plate 503. A stop bar 506 is fixedly installed on the side of the base plate 503 away from the sleeve 502. The length of the stop bar 506 is greater than the spacing of the arc rod 104. Symmetrical counterweights 505 are fixedly installed at both ends of the stop bar 506.

[0038] In this embodiment, the seat mechanism 500 unfolds downwards and contacts the arc-shaped rod 104, allowing the patient to sit down and rest. The arc-shaped rod 104, in conjunction with the fixed shaft 106, supports the seat mechanism 500. Rotating the stop rod 506 causes the base plate 503, seat cushion 504, and counterweight 505 to rotate. The rotation of the seat mechanism 500 shifts the center of gravity of the device forward, thereby causing the mounting frame 100 to rotate along the central axis of the first roller 2. The rotation of the mounting frame 100 causes the rubber anti-slip sleeve 4 to rotate until the rubber anti-slip sleeve 4 contacts the ground, thus realizing the unfolding of the seat mechanism. The seat mechanism 500 automatically limits the position of the mounting frame 100. When the patient retracts the seat mechanism 500, the center of gravity of the device can be shifted backward, thereby causing the mounting frame 100 to rotate in the opposite direction until the rubber anti-slip sleeve 4 leaves the ground and the second roller 3 contacts the ground, releasing the limitation on the mounting frame 100 and facilitating the patient's rehabilitation exercises. At this time, the fixed shaft 106, together with the second connecting rod 107, supports the seat mechanism 500. The inclined seat mechanism 500 can prevent the seat mechanism 500 from automatically unfolding when affected by external vibrations.

[0039] The working principle of this utility is as follows:

[0040] When in use, rotating the stop lever 506 causes the base plate 503, seat cushion 504, and counterweight 505 to rotate. The patient retracts the seat mechanism 500, causing the center of gravity of the device to shift backward, thereby causing the mounting frame 100 to rotate in the opposite direction along the central axis of the first roller 2 until the rubber anti-slip sleeve 4 leaves the ground and the second roller 3 contacts the ground. This automatically releases the restriction on the mounting frame 100 after the seat mechanism 500 is retracted, facilitating rehabilitation exercises for the patient. At this time, the fixed shaft 106, in conjunction with the second connecting rod 107, supports the seat mechanism 500. The inclined seat mechanism 500 can prevent the seat mechanism 500 from automatically unfolding when affected by external vibrations. The first roller 2 and the second roller 3 simultaneously contact the ground. The patient can push the arc-shaped rod 104 to move the device forward. The first roller 2, in conjunction with the second roller 3, can improve the stability of the device and prevent the device from overturning significantly when the first roller 2 or the second roller 3 contacts an obstacle, reducing the risk of the patient falling.

[0041] When the device is not in use or the patient needs to rest, rotating the stop lever 506 causes the base plate 503, seat cushion 504, and counterweight 505 to rotate, unfolding the seat mechanism 500. The rotation of the seat mechanism 500 shifts the center of gravity of the device forward, thereby causing the mounting frame 100 to rotate along the central axis of the first roller 2. The rotation of the mounting frame 100 causes the rubber anti-slip sleeve 4 to rotate until the rubber anti-slip sleeve 4 contacts the ground. This automatically limits the position of the mounting frame 100 after the seat mechanism 500 is unfolded, preventing the device from shifting when not in use. The seat mechanism 500 unfolds downward and contacts the arc-shaped rod 104, allowing the patient to sit down and rest. The arc-shaped rod 104, together with the fixed shaft 106, supports the seat mechanism 500.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
