Description

Technical Field

[0001] This utility model relates to the field of walking assistance technology, specifically a retractable walking assistance device. Background Technology

[0002] For patients after surgery, elderly people with limited mobility, and postpartum women, their legs often lack sufficient support and they are unable to walk independently due to reasons such as not having fully recovered or lack of physical strength. In these cases, they need to use walking aids to help them walk.

[0003] Existing walking aids are generally welded and cannot be folded. When folded up for storage, they take up a lot of space. In addition, walking aids come in two types: with wheels and without wheels. They need to be replaced according to the user's needs. Replacing the wheels takes a lot of time. Since the wheels are not carried around, they cannot be switched anytime and anywhere, which is quite inconvenient. Therefore, technological innovation and design optimization are needed to achieve an optimized, retractable walking aid. Utility Model Content

[0004] Existing walking aids are generally welded and cannot be folded. When folded up for storage, they occupy a large amount of space. Furthermore, walking aids come in two types: with and without wheels, requiring replacement based on the user's needs. Replacing the wheels takes considerable time, and since the wheels are not carried around, switching between them is inconvenient. To address these issues, this application provides a retractable walking aid device. By incorporating two U-shaped frames that can rotate around a fixed plate and a connecting mechanism that connects the two U-shaped frames, the device can be folded for storage, saving space. A rotating rod with wheels at one end and a limiting mechanism that restricts the rotation can adjust the user's walking style, improving the device's applicability.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A retractable walking aid device, comprising:

[0007] Two U-shaped frames;

[0008] A fixing block is fixed to the bottom end of two U-shaped frames. A rotating shaft is fixed to one side of the fixing block. A rotating rod rotates on the rotating shaft. A traveling wheel is fixed to one end of the rotating rod.

[0009] A rotating mechanism, located between two U-shaped frames, is used for rotating the two U-shaped frames;

[0010] A connecting mechanism, located between two U-shaped frames, is used to connect the two U-shaped frames;

[0011] A limiting mechanism is located on a fixed block and is used to limit the rotation rod.

[0012] In one possible implementation, the U-shaped frame includes a diagonal brace with a cylinder on one side, and a connecting rod fixed to the top of the diagonal brace and the cylinder.

[0013] In one possible implementation, the rotating mechanism includes two cylinders sleeved on two cylindrical bodies, the two cylinders being able to rotate inside the two cylinders, and a fixing plate being provided between the two cylinders, the fixing plate being fixedly connected to the two cylinders to facilitate the folding of the two U-shaped frames.

[0014] In one possible implementation, the connecting mechanism includes two U-shaped plates that are snapped onto two connecting rods, a support rod fixed between the two U-shaped plates, bolts threaded onto the U-shaped plates, and threaded holes at the bottom of the connecting rods. The bolts are threaded into the threaded holes. By aligning the U-shaped plates with the connecting rods and fixing the U-shaped plates and connecting rods with bolts, the two U-shaped frames can be supported.

[0015] In one possible implementation, the limiting mechanism includes a second U-shaped plate fixed to the side of the fixed block away from the rotating rod. A limiting post passes through the second U-shaped plate, and the end of the limiting post near the fixed block passes through the fixed block. Two limiting holes are opened on the side of the rotating rod near the fixed block, and the limiting post can be inserted into the limiting holes. A baffle is fixed on the limiting post between the second U-shaped plate and the fixed block. A spring is sleeved on the outside of the limiting post between the baffle and the second U-shaped plate. The limiting post can be pulled out of the limiting holes by pulling the block. At this time, the rotating rod can be twisted. When the limiting post is pulled again, the baffle will compress the spring. When the limiting post is released, under the action of the spring, the baffle will drive the limiting post to insert into the limiting holes to limit the rotating rod.

[0016] In one possible implementation, the limiting post can slide on the fixed block and the second U-shaped plate, and a pull plate is fixed to the end of the limiting post away from the fixed block, so that the limiting post can be pulled by the pull plate.

[0017] In one possible implementation, a rubber pad is fixed to the side of the rotating rod away from the walking wheel to improve the friction between the rotating rod and the ground.

[0018] In one possible implementation, the fixing blocks are fixed to the bottom of the diagonal bar and the cylinder, respectively.

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] 1. By setting up two U-shaped frames that can rotate around the fixed plate and a connecting mechanism that can connect the two U-shaped frames, this device can be folded and stored, saving the space occupied during storage.

[0021] 2. By setting a rotating rod with a walking wheel at one end and a limiting mechanism that can limit the rotation of the rod, the way the pen assists the user in walking can be adjusted according to the user's situation, thus improving the applicability of the device.

Detailed Implementation

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The instrument placement rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] This embodiment describes the specific structure of a retractable walking assistance device, see details below. Figures 1-4 As shown, a retractable walking aid device includes:

[0029] Two U-shaped frames;

[0030] A fixing block 18 is fixed to the bottom of two U-shaped frames. A rotating shaft 12 is fixed on one side of the fixing block 18. A rotating rod 1 rotates on the rotating shaft 12. A traveling wheel 10 is fixed to one end of the rotating rod 1.

[0031] A rotating mechanism is located between two U-shaped frames and is used for the two U-shaped frames to rotate.

[0032] A connecting mechanism, located between two U-shaped frames, is used to connect the two U-shaped frames;

[0033] The limiting mechanism is located on the fixed block 18 and is used to limit the rotation rod 1.

[0034] It is worth noting that the U-shaped frame includes a diagonal rod 2, a cylinder 7 is provided on one side of the diagonal rod 2, a connecting rod 3 is fixed at the top of the diagonal rod 2 and the cylinder 7, and a fixing block 18 is fixed at the bottom of the diagonal rod 2 and the cylinder 7 respectively.

[0035] Furthermore, when the U-shaped frame needs to be folded, the rotating mechanism includes two cylinders 5 sleeved on two cylinders 7. The two cylinders 7 can rotate inside the two cylinders 5. A fixing plate 6 is provided between the two cylinders 5. The fixing plate 6 is fixedly connected to the two cylinders 5, which facilitates the folding of the two U-shaped frames.

[0036] More importantly, after the U-shaped frame is unfolded, the connecting mechanism includes two U-shaped plates 8 that are clamped onto two connecting rods 3, a support rod 4 fixed between the two U-shaped plates 8, bolts 9 threadedly connected to the U-shaped plates 8, and threaded holes opened at the bottom of the connecting rods 3. The bolts 9 are threadedly connected to the threaded holes. The U-shaped plates 8 are aligned with the connecting rods 3, and the U-shaped plates 8 and the connecting rods 3 are fixed with the bolts 9, which can support the two U-shaped frames.

[0037] Furthermore, when it is necessary to limit the rotation rod 1, the limiting mechanism includes a U-shaped plate 14 fixed to the side of the fixed block 18 away from the rotation rod 1. A limiting post 11 passes through the U-shaped plate 14. The end of the limiting post 11 near the fixed block 18 passes through the fixed block 18. Two limiting holes 19 are opened on the side of the rotation rod 1 near the fixed block 18. The limiting post 11 can be inserted into the limiting holes 19. A baffle 17 is fixed on the limiting post 11 between the U-shaped plate 14 and the fixed block 18. The outside of the limiting post 11 is located between the baffle 17 and the U-shaped plate 14. A spring 16 is provided in the middle. By pulling the block, the limiting post 11 can be pulled out from the limiting hole 19. At this time, the rotating rod 1 can be twisted. When the limiting post 11 is pulled again, the baffle 17 will squeeze the spring 16. When the limiting post 11 is released, under the action of the spring 16, the baffle 17 will drive the limiting post 11 to insert into the limiting hole 19 to limit the rotating rod 1. The limiting post 11 can slide on the fixed block 18 and the U-shaped plate 14. A pulling plate 15 is fixed to the end of the limiting post 11 away from the fixed block 18, so that the limiting post 11 can be pulled by the pulling plate 15.

[0038] A rubber pad 13 is fixed to the side of the rotating rod 1 away from the walking wheel 10 to improve the friction between the rotating rod 1 and the ground.

[0039] When the staff needs to store the equipment, they can loosen bolt 9 to remove the U-shaped plate 8 from the connecting rod 3, thus separating the support rod 4 and the U-shaped plate from the connecting rod. At this point, the U-shaped frame can be rotated to fold the two U-shaped frames, thereby facilitating storage.

[0040] When it is necessary to change the walking mode of this device, the limiting post 11 can be pulled out from the limiting hole 19 by pulling the block. At this time, the rotating rod 1 can be twisted. When the limiting post 11 is pulled again, the baffle 17 will squeeze the spring 16. When the limiting post 11 is released, under the action of the spring 16, the baffle 17 will drive the limiting post 11 to insert into the limiting hole 19 to limit the rotating rod 1. The two ends of the rotating rod 1 correspond to two walking modes: moving and rolling, which can be easily changed according to the user's specific situation.

[0041] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
