The brake head 21 is located above the rotating shaft 12, and the latch 211 on the brake head 21 matches with the position of the slot 14 on the rotating shaft 12. When the latch 211 of the brake head 21 is inserted into the slot 14, the brake device 2 abuts against the rotating shaft 12 to lock the wheel 11, and when the latch 211 of the brake head 21 is released from the slot 14, the brake device 2 is released from the rotating shaft 12 to unlock the wheel 11. In the embodiment, the clamping tongue and the clamping groove are matched to brake the wheel, so that the impact force of the clamping tongue 211 of the brake head inserted into the clamping groove 14 when the wheel 11 is switched from a rolling state to a locking state can be reduced, the friction loss is reduced, and the service life of the wheel is prolonged. In addition, a plurality of clamping grooves 14 are arranged on the periphery of the rotating shaft 12, and the teeth between the adjacent clamping grooves are provided with guiding arc surfaces, so that the wheel 11 is guaranteed to rotate to any position, the clamping tongues of the braking head can be inserted into the clamping grooves in good time, and the wheel can be guaranteed to be locked instantly when needed. It should be noted that, the setting position and the number of the slots in this embodiment are only a preferred scheme, and the present invention is not limited thereto.
In this embodiment, the return device 3 is a spring 31, and the locking and unlocking device 4 is a pull wire 41. The brake head 21, the spring 31 and the pull wire 41 are connected in a matching way through the mounting block 5. The mounting block 5 is fixedly mounted on the fork beam 131 of the U-shaped seat 13, the spring 31 is arranged in the vertical direction, one end of the spring 31 is connected with the mounting block 5, the other end of the spring 31 is connected with the brake head 21, and the brake head 21 is suspended above the rotating shaft 12. Under the normal state, the brake head 21 keeps the clamping tongue 211 of the brake head 21 in the clamping groove 14 under the self weight to lock the wheel 11. In the unlocked state, the brake head 21 moves toward the spring 31 side and compresses the spring 31 to generate a restoring force, and the latch 211 of the brake head 21 is disengaged from the latch slot 14 to unlock the wheel 11. When the unlocking state is restored to the locking state, the spring 31 drives the braking head 21 to move downwards by using the resilience force generated by compression so as to restore the braking head 21 to the original position, and then the clamping tongue 211 of the braking head 21 is driven to be inserted into the clamping groove 14. One end of the pull wire 41 is connected with one end of the brake head 21 with the latch 211, the other end of the pull wire 41 is connected with the external control 9, the pull wire 41 is pulled through the external control 9 to drive the latch 211 of the brake head 21 to be separated from the slot 14, or the external control 9 is released to be reset through the pull wire 41, so that the latch 211 of the brake head 21 is inserted into the slot 14 under the self elastic force of the spring 31. As shown in fig. 1, the external control 9 is a control handle arranged on the upper outer side of the lower bracket, the patient presses the control handle, a pull wire 41 connected to the bottom of the control handle is pulled to unlock the self-locking wheel 1, and the walking aid can move at the moment. The patient releases the handle and the pull wire 41 attached to the bottom of the handle is released to lock the self-locking wheel 1, at which time the walker cannot be moved. The operation of switching from the unlocked state to the locked state is simplified, and the wheels can be switched from the unlocked state to the locked state instantly.
In an alternative embodiment, the locking and unlocking device 4 can be replaced by an electromagnetic locking and unlocking device. For example, the structure of the electromagnet and the silicon steel sheet is adopted, the silicon steel sheet is arranged on the brake head, and the electromagnet is arranged above the brake head. The electromagnetic locking device is not electrified in a normal state, the electromagnet is not attracted with the silicon steel sheet, and the brake head is inserted into the clamping groove to lock the wheel. And when the electromagnetic locking device is electrified in an unlocking state, the electromagnet attracts the silicon steel sheet to drive the brake head to move upwards to separate the unlocking wheel from the clamping groove.
