Technical Field

[0001] This utility model relates to the field of orthopedic walking aids, specifically a walking aid. Background Technology

[0002] Orthopedic walking aids are medical devices that assist patients with mobility impairments in walking. They are primarily used for individuals with lower limb injuries, post-operative rehabilitation, or limited mobility to reduce weight-bearing on the affected limb, maintain balance, and promote recovery. Common walking aids include walking frames and wheelchairs, which provide stable support for orthopedic patients. By distributing body pressure and reducing the risk of falls, walking aids help patients regain mobility and are suitable for situations involving fractures, joint replacements, arthritis, or muscle weakness. They are an important tool in orthopedic rehabilitation.

[0003] An orthopedic walking aid disclosed in Chinese Patent Publication No. CN206491995U adjusts the angle of the elbow support plate by adjusting the length of the electric push rod, thus making it suitable for various types of people (different heights, weights, etc.). The elbow support plate supports the patient's arm, reducing the support force on the patient's hands when using the walking aid and solving the problem of muscle fatigue in the elbow and shoulder when the patient walks for a long time. However, the overall functionality of the walking aid is limited, only assisting orthopedic patients in walking. In case of emergencies, it cannot effectively move or transport orthopedic patients, affecting the overall practicality of the walking aid. Utility Model Content

This type of walking aid incorporates multiple layers, including a base layer, a reinforcing layer, and an outer coating. The honeycomb structure of the base layer significantly reduces the overall weight of the walking aid while maintaining strength. Combined with an internal self-healing polymer, it can self-repair after damage, extending the lifespan of the walking aid. Meanwhile, the reinforcing layer on the outside of the base layer works synergistically to further enhance the stability and deformation resistance of the frame. The outer coating reduces friction between connecting parts, preventing wear and noise caused by direct contact between metal components. This effectively ensures the strength of the walking aid while reducing its weight, extending its lifespan and improving its stability during use. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-7 This utility model provides two technical solutions: Example 1: A walking aid includes a fixed frame 1, which has two sets. First slots 101 are formed on the left and right sides of the upper surface of the fixed frame 1, and support legs 102 are fixedly connected to the left and right sides of the lower surface of the fixed frame 1. Second slots 103 are formed on the right inner sides of the two fixed frames 1. Adjusting posts 3 are slidably connected inside the two sets of first slots 101. A reinforcing plate 4 is fixedly connected to the middle position of the two adjusting posts 3. A handle 401 is fixedly connected to one side of the upper surface of the reinforcing plate 4. An anti-slip rubber pad is provided on the outside of the handle 401. A connecting rod 5 is provided on the right inner side of the two fixed frames 1. The two ends of the connecting rod 5... The second slot 103, which is inserted into the two sets of fixed frames 1 at opposite positions, also includes an adjustment mechanism 2 and a limiting mechanism 6. The adjustment mechanism 2 is used to adjust the height of the adjustment column 3 at the top of the fixed frame 1, and the limiting mechanism 6 is used to limit the position of the connecting rod 5 in the middle of the two fixed frames 1. The first slot 101 facilitates the installation of the adjustment column 3. At the same time, the support leg 102 can effectively support the walker and act as a stretcher handle when the walker is used as a stretcher. The second slot 103 allows the connecting rod 5 to be inserted, thereby stably limiting the connecting rod 5 to the two sets of first slots 101.

[0016] The adjustment mechanism 2 includes rotating grooves 201 that are opened opposite to each other on the top of the left and right sides of the fixed frame 1. A screw 202 is threaded to the center of the outer side of the rotating groove 201. A movable plate 203 is fixed to the inner side of the screw 202. A through groove 301 for inserting the connecting rod 5 is opened in the center of the interior of the adjustment column 3. A first positioning groove 302 that is evenly spaced vertically on the outer side of the through groove 301 and engages with the first positioning rod 204 is opened. The first positioning rod 204 is fixed to the inner side of the movable plate 203. When the screw 202 rotates, it can drive the first positioning rod 204 to move through the movable plate 203. When the first positioning rod 204 is inserted into the through groove 301 at different heights on the adjustment column 3, the height of the walker can be adjusted according to the user's height.

[0017] The fixing frame 1 is provided with a base layer 7, a reinforcing layer 701, and an outer coating layer 702 from the inside out.

[0018] The base layer 7 is made of honeycomb carbon fiber composite material and filled with self-healing polymer. The honeycomb frame can effectively ensure the strength of the walker and reduce its weight. At the same time, the self-healing polymer can restore the original shape through chemical reaction when the internal structure is slightly damaged, thus extending the product's service life.

[0019] The reinforcing layer 701 is made of aluminum alloy, which has the characteristics of low density, high strength, good processing performance, and good oxidation resistance, further enhancing the stability and deformation resistance of the frame.

[0020] The outer coating 702 uses a polytetrafluoroethylene coating, which can reduce friction between the connecting parts in the walker, improve its service life, and prevent wear and noise caused by direct contact between metal parts.

[0021] Example 2 differs from Example 1 in that: a walking aid includes a fixed frame 1, which has two sets. First slots 101 are provided on the left and right sides of the upper surface of the fixed frame 1, and support legs 102 are fixedly connected to the left and right sides of the lower surface of the fixed frame 1. Second slots 103 are provided on the right ends of the inner sides of the two fixed frames 1. Adjusting columns 3 are slidably connected inside the two sets of first slots 101. A reinforcing plate 4 is fixedly connected to the middle position of the two adjusting columns 3. A handle 401 is fixedly connected to one side of the upper surface of the reinforcing plate 4. An anti-slip rubber pad is provided on the outside of the handle 401. A connecting rod 5 is provided on the right ends of the inner sides of the two fixed frames 1. Both ends of the connecting rod 5 are inserted into the second slots 103 on the two sets of fixed frames 1 at opposite positions. The walking aid also includes an adjustment mechanism 2 and a limiting mechanism 6. The adjustment mechanism 2 is used to adjust the height of the adjusting column 3 at the top of the fixed frame 1, and the limiting mechanism 6 is used to limit the connecting rod 5 at the middle position of the two fixed frames 1. When the walking aid is used as a stretcher, the support legs 102 act as stretcher handles.

[0022] The adjusting mechanism 2 includes rotating grooves 201 that are opened opposite each other inside the top ends of the left and right sides of the fixed frame 1. A screw 202 is threaded to the center of the outer side of the rotating groove 201. A movable disk 203 is fixed to the inner side of the screw 202. A first positioning rod 204 is fixed to the inner side of the movable disk 203. When the screw 202 rotates, it can drive the first positioning rod 204 to move through the movable disk 203. When the first positioning rod 204 rotates into the second positioning groove 501 on the connecting rod 5, the connecting rod 5 can fix the position between the top ends of the two sets of fixed frames 1.

[0023] The center of the adjusting column 3 is provided with a through groove 301 for inserting the connecting rod 5. The outer side of the through groove 301 is provided with a first positioning groove 302 that is evenly spaced vertically and engages with the first positioning rod 204. The through groove 301 facilitates the insertion of the connecting rod 5, and the connecting rod 5 enables the interconnection between the upper surfaces of the two sets of fixing frames 1.

[0024] The limiting mechanism 6 includes a rotary bar 601 rotatably connected to the right side of the fixed frame 1. Pull ropes 602 are fixed to both sides of the rotary bar 601.

Rotating the rotary bar 601 can cause the pull ropes 602 on both sides to wind up. At this time, the pull ropes 602 pull the movable block 603 to move and squeeze the spring 604 on one side. At the same time, the movable block 603 can drive the second positioning rod 605 to move. When the second positioning rod 605 is pulled out from the second positioning groove 501 on the connecting rod 5, the connecting rod 5 can be removed from the middle position of the two sets of fixed frames 1. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0025] In this embodiment, during use: by rotating the screw 202 on the fixing frame 1, the screw 202 can drive the first positioning rod 204 to be pulled out from the first positioning groove 302 on the adjusting column 3 via the movable disc 203. At this time, the height of the adjusting column 3 at the top of the fixing frame 1 can be adjusted, thereby adjusting the height of the walker. By rotating the first positioning rod 204 into the first positioning groove 302 at different positions on the adjusting column 3, the position of the adjusting column 3 after height adjustment can be fixed. When the rotary bar 601 on the fixing frame 1 is rotated, the rotary bar 601 pulls... When the pull ropes 602 on both sides are wound up, the pull ropes 602 pull the second positioning rod 605 through the movable block 603, so that the second positioning rod 605 can be pulled out from the second positioning groove 501 on the connecting rod 5. At this time, the separation between the two fixed frames 1 and the two connecting rods 5 can be completed. By inserting the two ends of the connecting rod 5 into the through grooves 301 on the top adjusting column 3 of the two fixed frames 1 respectively, and then inserting the first positioning rod 204 in the fixed frame 1 into the second positioning groove 501 on the connecting rod 5, the assembly and use of the walking aid stretcher can be completed.
