Abstract
Description
Technical Field
[0001] This utility model relates to the field of walking aid technology, and in particular to a telescopic component with a double locking structure and a telescopic walking aid with adjustable width. Background Technology
[0002] Walking aids are essential rehabilitation devices that assist the elderly, post-operative patients, or people with mobility impairments in walking and getting up. By providing stable support, they help users maintain balance, reduce lower limb load, thereby expanding their range of motion and enhancing their ability to live independently. Traditional walking aids typically consist of a U-shaped or quadrilateral frame equipped with hand support brackets. However, most existing products have a fixed width between the two support brackets. Due to significant differences in users' height, body shape, injury sites, and usage habits, a fixed width cannot meet the personalized needs of all users. For larger individuals, an excessively narrow width can cause restriction and discomfort; for smaller individuals, an excessively wide width makes it difficult to exert force and control, and increases the risk of collisions with obstacles, posing safety hazards. Therefore, adjustable walking aids with retractable widths on both sides are gradually becoming the development direction of the market.
[0003] Currently, the common method for adjusting the width of a walker is to set multiple positioning holes on the crossbar connecting the two side support frames, and change the width by inserting pins or bolts into different holes. While this design solves the problem of width adjustment to some extent, it has inherent defects in stability, safety, and operability. First, there must be a certain assembly gap between the pin or bolt and the positioning hole to ensure smooth insertion and removal, but this will cause the entire structure to wobble and make abnormal noises when under stress (especially under lateral or torsional forces) after locking. This wobble not only reduces the user's comfort and sense of security, but may also accelerate the wear of the connecting parts with long-term use, and even lead to locking failure. Second, the existing single-point locking method is not reliable enough. Once the only locking part loosens or falls off due to vibration or accidental contact, the two side support frames may suddenly move relative to each other, which can easily cause the user to lose balance and fall, resulting in a serious risk of secondary injury.
[0004] Therefore, there is an urgent need in this field for a telescopic component that provides convenient width adjustment while ensuring absolute stability, no wobbling, and reliable safety once locked. An innovative locking structure is needed to overcome the risks of gap wobbling and single-point failure inherent in existing single-point locking methods, providing users with a higher level of convenience, stability, and safety.

[0022] The following is combined with Figures 1 to 8 This invention describes a telescopic member with a double locking structure and a telescopic walking aid with adjustable width, according to an embodiment of the present invention.
[0023] A telescopic component with a double locking structure includes a left adjusting rod 2, a right adjusting rod 4, a locking member 5, and a fixing member 6. The left end of the right adjusting rod 4 can be telescopically inserted into the right end of the left adjusting rod 2. The locking member 5 is fixedly installed on the right end of the left adjusting rod 2. The right end of the left adjusting rod 2 is provided with a first clearance hole 10 at the position of the locking head of the locking member 5. The left end of the right adjusting rod 4 is evenly provided with a plurality of limiting holes 7. The locking head of the locking member 5 passes through the first clearance hole 10 and then inserts into the limiting hole 7 for limiting. One end of the fixing member 6 is rotatably installed on the right end of the locking member 5, and the other end of the fixing member 6 can be fixedly snapped to the left end of the right adjusting rod 4.
[0024] A telescopic component with a double locking structure is used to assist the elderly, postoperative patients, or people with mobility impairments in walking. The left end of the right adjusting rod 4 can be telescopically inserted into the right end of the left adjusting rod 2, and its length can be adjusted to suit users of different body sizes. A locking component 5 is fixedly installed on the right end of the left adjusting rod 2. Several limiting holes 7 are evenly distributed on the left end of the right adjusting rod 4. The locking head of the locking component 5 passes through the first clearance hole 10 and then inserts into the limiting holes 7 for positioning, ensuring stable installation of both components. One end of a fixing component 6 is rotatably installed on the right end of the locking component 5, and the other end of the fixing component 6 can be fixedly snapped onto the left end of the right adjusting rod 4, further securing the right adjusting rod 4 and the left adjusting rod 2, thus improving the stability of the telescopic component.
[0025] Specifically, the fastener 6, which is snapped onto one end of the right adjusting rod 4, is made of an elastic material. This facilitates the fastening or disassembly of the fastener 6 onto the right adjusting rod 4. The end of the fastener 6 that is snapped onto the right adjusting rod 4 is made of silicone or rubber.
[0026] Further explanation: the fixing component 6 includes a snap-fit block 601 and a connecting block 602. The snap-fit block 601 is located in the middle of the connecting block 602. One end of the connecting block 602 is rotatably connected to the right end of the locking component 5, and the other end of the connecting block 602 is a toggle end. This allows the user to swing the connecting block 602 via the toggle end to move the snap-fit block 601, facilitating snapping or disassembly. The snap-fit block 601 is C-shaped for easy snapping and disassembly. The snap-fit block 601 is made of silicone or rubber. When the snap-fit block 601 is snapped onto the right adjusting rod 4, the snap-fit block 601 has an inward contraction force, which can firmly fix it to the right adjusting rod 4.
[0027] To further explain, the connecting block 602 is connected to one end of the locking member 5 and is provided with an eccentric support block 603. The left adjusting rod 2 is provided with a second clearance hole. When the latching block 601 is latched onto the right adjusting rod 4, the eccentric support block 603 passes through the second clearance hole and supports the side of the right adjusting rod 4, further fixing the right adjusting rod 4, so that the right adjusting rod 4 and the left adjusting rod 2 are more fixed to each other.
[0028] Specifically, the locking component 5 includes a fixed sleeve 501, a limiting block 502, a limiting post 503, and a spring 504; the fixed sleeve 501 is fixedly fitted onto the right end of the left adjusting rod 2, and a clearance frame 505 protrudes from the front side of the fixed sleeve 501; the limiting block 502 is installed inside the clearance frame 505, and the middle part of the limiting block 502 is rotatably connected to the upper and lower sides of the clearance frame 505; the spring 504 is installed between the fixed sleeve 501 and the limiting block 502, and the spring 504 is installed at the left end of the limiting block 502; the limiting post 503 is located at the right end of the limiting block 502, and the limiting post 503 passes through the fixed sleeve 501 and the first clearance hole 10 and is inserted into the limiting hole 7. The middle part of the limiting block 502 is rotatably connected to the upper and lower sides of the relief frame 505. The spring 504 is installed between the fixing sleeve 501 and the limiting block 502, and the spring 504 is installed at the left end of the limiting block 502. The limiting post 503 is set at the right end of the limiting block 502. The user can press the limiting block 502 at the end where the spring 504 is installed, so that the limiting block 502 at the other end can drive the limiting post 503 to insert into or out of the limiting hole 7, which is convenient for use. The spring 504 is installed at the left end of the limiting block 502. The spring 504 can hold the limiting block 502, so that the limiting post 503 is kept inserted into the limiting hole 7. The front side of the fixing sleeve 501 has a relief frame 505 protruding. The limiting block 502 is installed in the relief frame 505. The relief frame 505 has an anti-accidental contact limit block 502 to prevent the user's body from touching and pressing the limit block 502.
