Abstract

The invention discloses a walking stick protection mechanism which comprises an installation mechanism installed on a tubular walking stick leg on the rear side of the end, close to the ground, of a walking stick, the installation mechanism is connected with a universal ball mechanism capable of rotating leftwards, rightwards and backwards, the front refers to the walking direction of a patient, the left and right are relative to the front, and similarly, the rear is opposite to the front. The universal ball mechanism is connected with an anti-skid supporting leg, the length of the supporting leg is smaller than the distance between the mounting mechanism and the bottom of the walking stick leg so that the supporting leg can be separated from the walking stick leg, and if the length of the supporting leg is equal to the length of the supporting leg, the supporting leg can rub the ground when the walking stick moves forwards, so that the supporting leg needs to be shorter. After the walking stick leg is separated from the supporting leg, under the support of the limiting mechanism, stable triangular support is formed between the supporting leg and the walking stick leg, the limiting mechanism limits the supporting leg to continuously rotate and forms a stable triangle with the walking stick leg and the ground, and compared with single-point landing, the triangle is more stable.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1 Please see Figs. 1 to 4This invention provides a cane anti-slip mechanism and a cane technical solution: A cane anti-slip mechanism includes a mounting mechanism installed on the tubular cane leg at the rear end of the cane near the ground. The mounting mechanism is connected to a swivel ball mechanism capable of rotating left, right, and rear. Here, "front" refers to the patient's walking direction, and "left" and "right" are relative to "front." Similarly, "rear" is relative to "front." The swivel ball mechanism is connected to an anti-slip support leg 1, and the length of the support leg 1 is less than the distance from the mounting mechanism to the bottom of the cane leg to facilitate separation between the support leg 1 and the cane leg. If they are the same length... When the cane moves forward, support leg 1 will rub against the ground. Therefore, support leg 1 needs to be shorter. It also includes a limiting mechanism between the omnidirectional ball joint and support leg 1. After the cane leg separates from support leg 1, a stable triangular support is formed between support leg 1 and cane leg under the support of the limiting mechanism. The limiting mechanism restricts support leg 1 from continuing to rotate, forming a stable triangle with the cane leg and the ground. Compared to a single point of contact, a triangle is more stable, thus preventing slippage. Furthermore, the omnidirectional ball joint provides multi-directional anti-slip compared to a unidirectional hinge connection. Support leg 1 has a support block 2 at its bottom, which can be shaped like a bun or a weight. The bottom is curved, making it less prone to scraping and getting stuck. The outside of support block 2 is covered with an anti-slip rubber sleeve to increase friction and prevent slippage, providing even greater friction on tiles or other smooth surfaces.

[0019] The mounting mechanism includes a fixed sleeve 3 that fits onto the cane leg, and a swivel ball mechanism is mounted on the fixed sleeve 3 for easier fixation. The swivel ball mechanism includes a ball shell 4 fixed to the rear side of the fixed sleeve 3 and a ball core 5 installed inside the ball shell 4. The lower end of the ball shell 4 is open, and the support leg 1 is fixed to the lower end of the ball core 5. Under the action of gravity, the support leg 1 can be in a vertical state to support the cane leg when it slides. Under the action of gravity, the support leg 1 is always vertical, and it will only touch the ground for support when the cane leg tilts excessively.

[0020] The limiting mechanism includes a retaining ring 6 extending downward from the opening of the spherical shell 4, and the support leg 1 can abut against the retaining ring 6 after opening to achieve limiting and support. After the support leg 1 separates from the cane leg, the retaining ring 6 restricts further rotation and achieves support and fixation, thereby forming a stable triangle with the ground.

[0021] Example 2 like Figs. 5 to 7 As shown, based on Embodiment 1, instead of the support leg 1 being always vertical in Embodiment 1, this preferred embodiment also includes a suction mechanism disposed between the support leg 1 and the crutch leg. The suction mechanism will separate when the crutch leg moves forward quickly or tilts at an excessive angle. The suction mechanism can accommodate the support leg 1 and will not shake or separate during walking. When the speed is too fast, the suction mechanism opens under the action of inertia, and the support leg 1 opens. Or, if the crutch leg tilts at an excessive angle, the weight of the support leg 1 is greater than the suction force of the suction mechanism and separates, thus achieving protection.

[0022] The magnetic attraction mechanism includes a first annular magnet 7 sleeved on the cane leg and a second annular magnet 8 sleeved on the support leg 1. The second magnet 8 can be attracted to the first magnet 7, and the cane is stored by the attraction between the first magnet 7 and the second magnet 8. It will not shake or separate during walking. When the speed is too fast, the support leg 1 opens due to inertia, or the cane leg tilts at too large an angle, and the weight of the support leg 1 exceeds the attraction force of the first magnet 7 and the second magnet 8, thus separating the cane and providing protection. In the vertical position, the cane leg is parallel to the support leg 1, and the first magnet 7 is threaded with a first fastening knob 9 that abuts against the cane leg so that the position of the first magnet 7 can be adjusted up and down. The second magnet 8 is provided with a second fastening knob 10 so that it corresponds to the position of the first magnet 7. By adjusting the distance to the fixing sleeve 3, the attraction force required for separation is changed, thereby changing the maximum tilt angle of the cane leg when the support leg 1 is separated. The connection between the spherical shell 4 and the spherical center 5 is the fulcrum. The attraction force of the first magnet 7 and the second magnet 8 forms a torque between the fulcrum and the first magnet 7. The smaller the distance, the smaller the torque, and the easier it is to separate, thus reducing the maximum tilt angle during separation.

[0023] The fixing sleeve 3 is equipped with a third fastening knob 11 that can hold the crutch leg tightly. By adjusting the distance from the end of the support leg 1 to the ground through the fixing sleeve 3, the maximum tilt angle of the crutch leg when the support leg 1 is on the ground can be changed. Adjusting the distance from the bottom of the support leg 1 to the ground can change the maximum tilt angle of the crutch leg when it is on the ground.

[0024] A cane, including the aforementioned cane protection mechanism.

[0025] Working principle: When the support leg 1 is vertical, if the cane leg moves too far forward or slides to one side, the support block 2 on the lower side of the support leg 1 will contact the ground, forming a triangle between the support leg 1 and the ground to provide support, thereby preventing further sliding and avoiding a fall. When the first magnet 7 and the second magnet 8 are attracted together, the cane leg has a small tilt angle and the support leg 1 is stored in a more compact and convenient manner during normal walking. If it suddenly slides due to inertia, or if the tilt angle is too large and the downward component force is greater than the attraction force, the first magnet 7 and the second magnet 8 will separate, and the support leg 1 will provide ground support, increasing the stability of the cane.
