Description

Technical Field

[0001] This utility model relates to the field of cane devices, and in particular to an underarm cane that is easy to adjust and disassemble. Background Technology

[0002] Crutches are rehabilitation aids to help people with mobility impairments or post-operative patients walk. They are primarily used to reduce weight-bearing on the lower limbs, maintain balance, and facilitate safe movement. By supporting part of the body's weight, they help patients regain mobility and are suitable for conditions such as fractures, joint injuries, or muscle weakness. Correct use can reduce the risk of falls and accelerate the recovery process, but the method of use needs to be adjusted according to individual circumstances to avoid additional injuries caused by improper support.

[0003] Existing crutches typically consist of multiple support rods, armpit supports, handles, anti-slip blocks, bolts, and other structures. The support rods are fixed together with bolts to form the main body of the crutches. Armpit supports are installed at the top of the support rods to provide support for the patient's body. Handles are installed below the armpit supports for easy gripping and use. Anti-slip blocks are installed at the bottom of the support rods to provide a non-slip effect for the main body of the crutches, preventing the user from falling and getting injured while using the crutches.

The connecting component includes a connecting rod 9, which is fixedly connected to the bottom of the U-shaped tube 7. A limiting hole 13 is provided on the outer side of the connecting rod 9. The connecting rod 9 provides support for the U-shaped tube 7, so that it can operate stably. Through the cooperation between the various structures of the telescopic mechanism, the height adjustment and fixation of the armpit support 1 can be achieved, so that the cane can better support the user's movement.

[0013] Reference Figures 3-4The adjustment mechanism includes a positioning component, a fastening component, and a retraction component. The positioning component includes a support rod 15, which is slidably connected inside the connecting rod 9. A ball bearing 14 is slidably connected to the outside of the support rod 15, and the ball bearing 14 and the limiting hole 13 engage with each other. A spring 16 is installed inside the support rod 15, and a slider 17 is slidably connected inside the support rod 15. A limiting hole 18 is provided on the outside of the support rod 15. The support rod 15 provides support for the connecting rod 9, enabling it to operate stably. The ball bearing 14 and the limiting hole 13 cooperate to fix the connection between the support rod 15 and the connecting rod 9, preventing separation during operation. The slider 17 protects the ball bearing 14 from getting stuck in the gap of the spring 16, and the spring 16 provides a reset effect for the ball bearing 14. The retraction component includes a vertical rod 20, which is slidably connected inside the support rod 15. The vertical rod 20 and the support rod 15 cooperate to achieve the desired adjustment. The height of the cane is adjustable to accommodate users of different heights. A ball bearing 19 is slidably connected to the outer side of the vertical rod 20, and the ball bearing 19 engages with a limiting hole 18. A spring 21 is installed inside the vertical rod 20, and a slider 22 is slidably connected inside the vertical rod 20. The ball bearing 19 and the limiting hole 18 work together to achieve a fixed height after adjustment, preventing the adjusted height from shifting. The slider 22 protects the ball bearing 19 from getting stuck in the gap of the spring 21, and the spring 21 provides a reset effect for the ball bearing 19. The fastening assembly includes a fastening clip 23, which is fixedly connected to the end of the support rod 15. A fixing sleeve 24 is slidably connected to the outer side of the vertical rod 20. The fastening clip 23 and the fixing sleeve 24 are connected by threads. The cooperation of the fastening clip 23 and the fixing sleeve 24 secures the cane after height adjustment, preventing height changes when the cane supports the user.

[0014] Reference Figure 3 , Figure 4 and Figure 6The fixing component includes a slide rod 10, which is slidably connected to the outside of the connecting rod 9. A positioning hole 25 is provided on the outside of the connecting rod 9. A positioning rod 12 is slidably connected to the outside of the slide rod 10, and the positioning rod 12 and the positioning hole 25 are engaged with each other. A handle 11 is fixedly connected to the outside of the slide rod 10. Through the cooperation of the positioning rod 12 and the positioning hole 25, the position of the slide rod 10 can be adjusted and fixed, thereby allowing the position of the handle 11 to be adjusted, thus facilitating support for the user using the cane. The support component includes a fixing rod 26, which is slidably connected to the vertical rod 20. Inside, a positioning block 27 is fixedly connected to one end of the fixing rod 26, and a support block 30 is fixedly connected to the other end of the fixing rod 26. A limit block 29 is fixedly connected to the outside of the support block 30, and a compression spring 28 is sleeved on the outer periphery of the fixing rod 26. Through the cooperation of the fixing rod 26, the positioning block 27 and the compression spring 28, the vibration and impact generated when the user moves with the cane are reduced, so that the user will not feel uncomfortable when moving with the cane. The support block 30 provides an anti-slip effect for the cane, so that the user will not slip and fall when moving with the cane.

[0015] Working principle: During use, when the support height needs to be adjusted according to the user's arm length, the ball bearing 5 can be pressed to retract into the connecting rod 2, pushing the slider 4 to slide. The slider 4 pushes the spring 3 to retract, allowing the armpit support 1 to be pulled to adjust the support height. When adjusted to the appropriate position, the limiting hole 6 causes the spring 3 to push the slider 4 to move, and the slider 4 pushes the ball bearing 5 to reset and engage with the limiting hole 6, thus fixing the adjusted height. When the position of the grip 11 needs to be adjusted, the positioning rod 12 can be pulled to disengage from the positioning hole 25, allowing the slide rod 10 to move. When adjusted to the appropriate position, the positioning rod 12 is pushed to reset and engage with the positioning hole 25, thus fixing the adjusted position. When the height needs to be adjusted according to the user's arm length, the support height can be adjusted according to the user's arm length. When ... When adjusting the height of the cane, the user can press the ball bearing 3 19 to slide it into the vertical rod 20, which will push the slider 3 22 to slide and push the spring 3 21 to retract. At this time, the height of the cane can be adjusted by pulling the vertical rod 20. When the height is adjusted to the appropriate position of the limiting hole 3 18, the spring 3 21 pushes the slider 3 22 to move, which pushes the ball bearing 3 19 to reset and the limiting hole 3 18 to engage, thereby fixing the adjusted height. When the cane needs to be disassembled and stored, the user can press the ball bearing 3 19, then pull the vertical rod 20 out of the support rod 15, then press the ball bearing 2 14, then pull the support rod 15 out of the connecting rod 9, then press the ball bearing 1 5, and then pull the armpit support 1 and the connecting rod 2 out of the U-shaped tube 7. At this time, the cane is disassembled, making it easier to store and transport.
