Detailed implementation mode

[0020] In order to enable those skilled in the art to better understand the present utility model, the technical solutions of the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] As Figures 1-5 shown, a walking aid of the present utility model includes a support rod 1. A round hole 11 is opened at the top of the support rod 1. A moving rod 12 is slidably assembled inside the round hole 11. A crank shaft 13 is fixedly installed at the upper end of the moving rod 12. A horizontal shaft 14 is fixedly installed on the upper left side of the crank shaft 13. A protective pad 15 is fixedly installed on the upper side of the horizontal shaft 14;

[0022] A vertical groove 16 communicating with the round hole 11 is opened on the front side of the support rod 1. A sliding groove 17 matching the position of the vertical groove 16 is opened on the front side of the moving rod 12. A slider 18 is slidably assembled inside the sliding groove 17. A first locking assembly is provided between the slider 18 and the moving rod 12. A second locking assembly is provided between the slider 18 and the vertical groove 16. A holding assembly is provided on the front side of the slider 18.

[0023] In the initial state, both the first locking assembly and the second locking assembly are in a locked state. The horizontal shaft part of the crank shaft 13 is used for the patient's hand to hold. When the hand is used as a support point, the hand holds on the horizontal shaft part of the crank shaft 13. When walking, the support rod 1 contacts the ground to provide a stable support force to assist the user in walking. When the patient's arm strength is insufficient and the support position needs to be changed, the locking of the second locking assembly is released, and the moving rod 12 is moved up and down to change the height of the crank shaft 13 and the horizontal shaft 14 to match the position under the patient's armpit. After the adjustment is completed, the second locking assembly is locked again. When the patient uses it, the armpit is placed against the protective pad 15, and the hand can hold the holding assembly to exert force. Such a use method can change the support point and is also applicable to patients of different heights, with stronger practicability and functionality. At the same time, when patients with different arm lengths use it, the lockings of the first locking assembly and the second locking assembly are released synchronously, and the position of the holding assembly can be adjusted to facilitate the use of patients with different arm lengths, further improving the practicability.

[0024] The first locking assembly includes a locking circular block 19. A number of circular locking grooves 191 are arranged vertically on the inner wall at the rear side of the sliding groove 17. A locking groove is provided at the rear side of the slider 18. The locking circular block 19 is slidably assembled inside the locking groove. The rear side of the locking circular block 19 extends into one of the circular locking grooves 191. A first spring 20 is fixedly installed on the front side of the locking circular block 19. One end of the first spring 20 away from the locking circular block 19 is fixedly connected to the inner wall of the locking groove.

[0025] The holding assembly includes a holding rod 21. A connecting rod 22 is fixedly installed at the center of the front side of the locking circular block 19. The front end of the connecting rod 22 extends out of the slider 19. The holding rod 21 is fixedly connected to the front end of the connecting rod 22.

[0026] When it is necessary to support the patient's armpit, the patient can hold the holding rod 21 with his hand to assist in exerting force for the patient to move. In the initial state, the elastic force of the first spring 20 pushes the locking circular block 19 to connect with one of the circular locking grooves 191. After unlocking the second locking assembly, the medical staff only needs to move the holding rod 21 up and down, and the whole moving rod 12 can be driven by the holding rod 21 to move up and down to adjust the supporting height of the crankshaft 13 and the horizontal shaft 14. When it is necessary to adjust the use height of the holding rod 21, while unlocking the first locking assembly, the medical staff can also pull the holding rod 21 to move. The holding rod 21 generates a pulling force to pull the locking circular block 19 back into the locking groove, releasing the connection with the circular locking groove 191. After the release, move the slider 18 up and down until it reaches the appropriate position, and then release the holding rod 21, so that the first spring 20 extends to push the locking circular block 19 to connect with one of the circular locking grooves 191 again. The operation is simple and convenient, and it is suitable for patients with different arm lengths.

[0027] The second locking assembly includes an assembly block 23. The assembly block 23 is fixedly installed on the upper side of the slider 18. A number of connecting grooves 24 are vertically provided on the inner walls on both the left and right sides of the vertical groove 16. Installation grooves are provided on both the left and right sides of the assembly block 23. Square blocks 25 are slidably assembled inside the two installation grooves. One side of the two square blocks 25 away from each other extends into one of the connecting grooves 24 on the left and right sides respectively. Second springs 26 are fixedly installed on the sides of the two square blocks 25 close to each other. One end of the two second springs 26 close to each other is fixedly connected to the inner walls of the two installation grooves respectively. A sleeve 27 is sleeved on the circumference of the holding rod 21. A first connecting rope 28 is fixedly installed on the circumference of the sleeve 27. A second connecting rope 29 is fixedly installed on the sides of the two square blocks 25 close to each other. One end of the first connecting rope 28 is fixedly connected to the circumference of the second connecting rope 29.

[0028] In the initial state, the driving force of the two second springs 26 pushes the two square blocks 25 to connect with the two connecting grooves 24. In this state, the position of the moving rod 12 cannot be adjusted. When it is necessary to adjust the position of the moving rod 12, the medical staff holds the sleeve 27 and pulls the sleeve 27 to move. The pulling force generated by the sleeve 27 pulls the first connecting rope 28 to move. The first connecting rope 28 drives the second connecting rope 29 to generate a pulling force, synchronously pulling the two square blocks 25 to move closer to each other to release the connection with the two connecting grooves. The medical staff can move the holding rod 21 up and down to adjust the position of the moving rod 12, which is simple and convenient to adjust. When it is necessary to adjust the position of the holding rod 21, while the medical staff pulls the holding rod 21 with the hand, the finger synchronously drives the sleeve 27 to move, and the locking of the first locking component and the second locking component can be completed simultaneously, and the operation is simple and convenient. A limiting block is provided at one end of the holding rod 21 away from the support rod 1, which is convenient for the medical staff to pull the holding rod 21 to move.

[0029] A non-slip shock-absorbing pad 30 is fixedly installed at the bottom of the support rod 1; when the non-slip shock-absorbing pad 30 contacts the ground, the vibration in contact with the ground can be reduced, and it plays a role in anti-slip.

[0030] According to the above overall description, when the present utility model is in use, the heights of the horizontal axis 14 and the crankshaft 13 can be adjusted according to the users of different heights, and the applicability is strong. When the patient needs the armpit as a support point, the height of the moving rod 12 can be adjusted to match the armpit height of the patient, and the support force is jointly provided by the horizontal axis 14 and the crankshaft 13. When the patient needs to support with the arm, the transverse axis part of the crankshaft 13 can be directly held, and the function is more comprehensive and the practicability is strong.
