Description

Technical Field

[0001] This utility model belongs to the field of rehabilitation assistive devices, and in particular relates to a multifunctional foldable walking aid. Background Technology

[0002] Walking aids are medical devices that assist people with mobility impairments (such as the elderly, post-operative rehabilitation patients, and people with disabilities) in achieving mobility, balance, and lower limb support. Their core components include left and right support frames, handrails, and non-slip support legs. For example, utility model patent CN221636577U provides a walking aid for lower limb rehabilitation walking training, solving the problem of needing to replace walking aids due to varying mobility requirements at different rehabilitation stages. However, this walking aid cannot be folded, resulting in insufficient foldability and portability, occupying a significant amount of space, and making it inconvenient for packaging, transportation, and storage. Furthermore, the walking aid's functions and usage methods are relatively limited, failing to meet the growing needs of users. Summary of the Invention

[0003] Based on the aforementioned problems in the existing technology, this utility model provides a multifunctional foldable walking aid, including a left support frame, a right support frame, a main connecting rod, and a conversion connecting sleeve. The conversion connecting sleeve includes a vertical sleeve for rotatably fitting onto the left / right support frame, and a horizontal sleeve for fitting onto the main connecting rod on one side of the vertical sleeve. Each of the left and right support frames is fitted with a conversion connecting sleeve, and both ends of the main connecting rod are fitted onto the two conversion connecting sleeves respectively.

[0004] The vertical sleeve is provided with a fixing hole and a folding hole. The folding hole is an arc-shaped strip hole extending circumferentially along the vertical sleeve. The arc angle span of the folding hole is greater than or equal to 90°. The conversion connecting sleeve is fixedly installed to the left / right support frame by passing through the fixing hole and the left / right support frame simultaneously through the connecting structure (the connecting structure includes common fixed connecting structures such as pins, screws and bolts, preferably bolts) or passing through the folding hole and the left / right support frame simultaneously.

[0005] The vertical sleeve is provided with a fixing hole and a moving hole. The moving hole is an arc-shaped strip hole extending circumferentially along the vertical sleeve. The arc angle span of the moving hole is less than or equal to 60°. The conversion connecting sleeve is fixedly installed to the left / right support frame by passing through the fixing hole and the left / right support frame simultaneously through the connecting structure (the connecting structure includes common fixed connecting structures such as pins, screws and bolts, preferably bolts) or passing through the moving hole and the left / right support frame simultaneously.

[0006] The horizontal sleeve is provided with triangular reinforcing plates on one or both sides, and the triangular reinforcing plates are fixedly connected to the side of the vertical sleeve.

[0007] The multifunctional foldable walker also includes a locking structure, which includes a rotating sleeve that is movably sleeved with the left / right support frame and a fixed sleeve that is fixedly sleeved with the left / right support frame. The rotating sleeve cannot rotate relative to the main connecting rod. A locking groove is provided on one side of the fixed sleeve, and a locking hook that matches the locking groove is provided on one side of the rotating sleeve. The locking hook can be operably inserted into the locking groove and restricts the relative rotation of the rotating sleeve and the fixed sleeve.

[0008] The rotating sleeve has a first connecting part on one side, and an unlocking link is fixedly installed on the first connecting part. The two ends of the unlocking link are respectively fixedly connected to the first connecting parts of the rotating sleeve of the left support frame and the right support frame. The fixed sleeve is located below the rotating sleeve, and a second connecting part is provided on one side of the fixed sleeve. The locking groove is located above the second connecting part and opens upward. The locking hook extends downward. A reinforcing link is fixedly installed on the second connecting part, and the reinforcing link is fixedly connected to the other side of the left / right support frame where it is located.

[0009] The first connecting part is fixedly sleeved by bolts and unlocking rods, the fixed sleeve is fixedly sleeved by bolts and left / right support frames, and the second connecting part is fixedly sleeved by bolts and reinforcing rods.

[0010] The multifunctional foldable walking aid also includes a shift sleeve. A number of shift holes are arranged sequentially from top to bottom on one side of the shift sleeve. The left / right support frame is provided with positioning holes that match the shift holes. The shift sleeve slides up and down on the left / right support frame, and the shift sleeve is fixed to the left / right support frame by passing through the positioning hole and any shift hole simultaneously through a connecting structure.

[0011] The bottom of the gear shift sleeve is provided with an anti-slip pad, and the lower surface of the anti-slip pad is provided with several annular grooves. All the annular grooves are arranged concentrically. The anti-slip pad is made of soft material. The annular grooves can improve the anti-slip ability of the anti-slip pad and its adaptability to uneven ground.

[0012] The transverse sleeve of the conversion connecting sleeve is fixedly connected to the main connecting rod by bolts, which facilitates the installation and disassembly of the main connecting rod, improves the overall installation and disassembly efficiency, and reduces the dependence on welding, thereby reducing production costs.

[0013] The beneficial effects of this utility model are as follows: Compared with the traditional welding connection, the use of the conversion connecting sleeve and bolts to fix the left support frame, right support frame and main connecting rod can simplify the installation process of the walker, reduce production costs and improve installation efficiency. In addition, the conversion connecting sleeve can realize the rotation connection, so that the walker has the ability to be folded, which is convenient for packaging, transportation and storage.

[0014] In addition, the conversion connector is equipped with fixing holes, folding holes, and moving holes, which enriches the functions and usage of the walker. The fixing holes can achieve a completely fixed connection with high structural strength, making it suitable for application scenarios with many fixed supports. The folding holes can accommodate a large rotation of the support frame, thereby enabling the walker to flip and unfold, reducing the space occupied and facilitating storage. The moving holes can allow the walker to undergo a small range of forward and backward misalignment deformation, combining deformation and fixation, making it suitable for application scenarios with frequent movement.

[0015] Meanwhile, the height adjustment feature allows the walker to be adjusted to accommodate people of different heights, thus improving the user experience. Attached Figure Description

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] As attached Figure 1-8The multifunctional foldable walking aid shown includes a left support frame 1, a right support frame 2, a main connecting rod 3, a conversion connecting sleeve 4, a locking structure 5, and a gear shift sleeve 6. The left support frame 1 and the right support frame 2 have the same structure, both being inverted "U" shapes. The conversion connecting sleeve 4 includes a vertical sleeve 7 for rotatably fitting onto the left / right support frame. One side of the vertical sleeve 7 is provided with a horizontal sleeve 8 for fitting onto the main connecting rod 3. The vertical sleeve 7 and the horizontal sleeve 8 form a "T" shape. Triangular reinforcing plates 9 are provided on the upper and lower sides of the horizontal sleeve 8, and the triangular reinforcing plates 9 are fixedly connected to the side of the vertical sleeve 7. Each of the left support frame 1 and the right support frame 2 is fitted with a conversion connecting sleeve 4. The two ends of the main connecting rod 3 are respectively fixedly fitted onto the horizontal sleeves 8 of the two conversion connecting sleeves 4 by bolts. The side of the left / right support frame with the main connecting rod 3 installed through the conversion connecting sleeve 4 is the front side. One side of the vertical sleeve 7 is provided with a fixing hole 10, a moving hole 11, and a folding hole 12 from top to bottom. The fixing hole 10 is a common round hole or a threaded hole. The moving hole 11 and the folding hole 12 are both arc-shaped strip holes extending circumferentially along the vertical sleeve 7. The arc angle span of the moving hole 11 is 60° and the midpoint of the moving hole 11 is on the same vertical line as the fixing hole 10. The arc angle span of the folding hole 12 is 90° and one end of the folding hole 12 is on the same vertical line as the fixing hole 10. The conversion connecting sleeve 4 is fixedly installed to the left / right support frame by passing through the fixing hole 10 and the left / right support frame simultaneously through the connecting structure. At this time, the walking aid cannot be deformed and is in fixed support mode; or The connecting structure passes through both the movable hole 11 and the left / right support frame and is fixedly installed to the left / right support frame. At this time, the left support frame 1 and the right support frame 2 can be slightly misaligned and deformed relative to each other, which is the movable mode. The user can move the support frame back and forth as needed to achieve support during the movement process; or the connecting structure passes through both the folding hole 12 and the left / right support frame and is fixedly installed to the left / right support frame. At this time, the left support frame 1 and the right support frame 2 can rotate 90° relative to the conversion connecting sleeve 4, thereby realizing the unfolding of the walker. In practical applications, the extension direction of the folding hole 12 can also be changed during production to realize the folding of the walker. In this embodiment, bolts are used as the connecting structure.

[0026] The locking structure 5 includes a rotating sleeve 13 that is movably sleeved to the front side of the left / right support frame, and a fixed sleeve 14 that is fixedly sleeved to the front side of the left / right support frame. The fixed sleeve 14 is fixedly sleeved to the left / right support frame by bolts. A first connecting part 15 is provided on one side of the rotating sleeve 13. An unlocking link 16 is fixedly installed on the first connecting part 15 by bolts. The two ends of the unlocking link 16 are respectively fixedly connected to the first connecting part 15 of the rotating sleeve 13 of the left support frame 1 and the right support frame 2. The unlocking link 16 is parallel to the main link 3 so that the rotating sleeve 13 cannot rotate relative to the main link 3. The fixed sleeve 14 is located below the rotating sleeve 13. A second connecting part 17 is provided on one side of the fixed sleeve 14. The upper part is provided with an upward-opening locking groove 18. The second connecting part 17 is fixedly installed with a reinforcing connecting rod 19 by bolts. The reinforcing connecting rod 19 extends backward and is fixedly connected to the rear side of the left / right support frame where it is located by welding or other means. One side of the rotating sleeve 13 is provided with a locking hook 20 that matches the locking groove 18. The locking hook 20 extends downward. Under the action of the unlocking connecting rod 16 and the weight of the rotating sleeve 13 itself, the locking hook 20 automatically inserts downward into the locking groove 18 and restricts the relative rotation of the rotating sleeve 13 and the fixed sleeve 14. By holding the unlocking connecting rod 16 and lifting the rotating sleeves 13 on both sides at the same time, the locking hook 20 and the locking groove 18 can be separated, the locking state can be released, and the left / right support frame can be rotated for movement or folding.

[0027] The gear sleeve 6 has several gear holes 21 arranged sequentially from top to bottom on one side. The left / right support frame has positioning holes 22 that match the gear holes 21. The gear sleeve 6 slides up and down on the left / right support frame. The gear sleeve 6 is fixed to the left / right support frame by passing through the positioning hole 22 and any gear hole 21 simultaneously through a connecting structure. The connecting structure here can also be a bolt or a pin. The bottom of the gear sleeve 6 is provided with an anti-slip pad 23. The lower surface of the anti-slip pad 23 is provided with two annular grooves 24, which are concentrically arranged.

[0028] The walking aid provided in this embodiment is equipped with a gear sleeve 6. According to actual needs, the gear hole 21 and positioning hole 22 corresponding to the required height are selected and matched. The relative positions of the left / right support frame and the gear sleeve 6 can be fixed by using bolts or pins to pass through the gear hole 21 and positioning hole 22, thereby realizing the adjustment of the height of the walking aid.

[0029] The walking aid has three modes of use, such as Figure 7 The upper dotted line bolts are used to meet three different usage requirements. The first is the fixed support mode, which is equivalent to a traditional walker. It cannot be folded or deformed. The main connecting rod 3 or the top of the support frame can be used as a handrail. It has greater structural strength, a higher load-bearing limit, and is more stable and safer.

[0030] The second type is the moving mode, such as Figure 7 The walker uses the dotted bolt below, allowing for slight deformation. By holding the unlocking lever 16 and pulling it upwards, the locking hook 20 disengages from the locking groove 18. At this point, the left / right support frame can be moved forward or backward by hand using the unlocking lever 16. Alternatively, the unlocking lever 16 can be pulled up and fixed using other auxiliary structures such as ropes, and then the left / right support frame can be moved forward or backward by hand. When not moving, the unlocking lever 16 can be lowered to achieve the traditional support method.

[0031] The third type is the folding mode, such as... Figure 7 The conversion connecting sleeve 4 is installed on the left / right support frame by passing a solid bolt through both the folding hole 12 and the left / right support frame. At this time, the left / right support frame can be opened or folded by unlocking the unlocking link 16 and rotating it, which is convenient for storage and transportation. The rotation of the left / right support frame can be locked by the locking structure 5, thereby realizing the function of fixed support.

[0032] The walking aid provided by this utility model is easy to assemble and disassemble, and has multiple usage methods and functions to meet more user needs.

[0033] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
