Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings, but it is not limited thereto. Any modifications or equivalent substitutions to the technical solution of this utility model that do not depart from the spirit and scope of the technical solution of this utility model shall be covered within the protection scope of this utility model.

[0020] like Figure 1 and Figure 2 As shown, this utility model proposes a child handrail for a digital treadmill, which is symmetrically and fixedly installed on the bottom surface of the handrail 4 on both sides of the digital treadmill. It is used to adapt to children or patients with shorter stature for rehabilitation sequences, and at the same time can play a safety protection role.

[0021] Specifically, the children's handrail of the digital treadmill is composed of three parts: a fixing mechanism 1, an adjustment mechanism 2, and a handrail assembly 3. The fixing mechanism 1 is fixedly installed on the bottom surface of the treadmill handrail 4 and includes two vertical fixing rods and two fixing bases. Both fixing bases are fixedly connected to the treadmill handrail 4, and the vertical fixing rods are fixedly connected to the fixing bases.

[0022] The handrail assembly 3 consists of a long shaft 32 and two short shafts 31. The two short shafts 31 are located on one side of two vertical fixed rods, with one end connected to the vertical fixed rods via an adjustment mechanism 2. The long shaft 32 is set along a direction parallel to the track, and its upper and lower sides are fixedly connected to the two short shafts 31 respectively. In use, the handrail assembly 3 can rotate 360° and can be locked via the adjustment mechanism 2, thereby adjusting the height of the handrail assembly 3 to suit the needs of different people.

[0023] The adjusting mechanism 2 is based on a bearing seat 24. A fixing interface 28 is located on the left side of the bearing seat 24 for connecting to a vertical fixing rod. A transverse through-hole is formed inside the bearing seat 24, within which a limiting component is installed. This limiting component consists of a limiting shaft 21 and a handle 26. The limiting shaft 21 is T-shaped and positioned within the through-hole of the bearing seat 24, with its right end abutting against the right end face of the bearing seat 24. First limiting teeth are located on both sides of the right end face of the limiting shaft 21 to engage with a bushing assembly, thus limiting the rotation of the bushing assembly. A threaded hole is located at the left end of the limiting shaft 21 for engaging with the handle 26. The handle 26 is located on the left side of the bearing seat 24 and is threadedly connected to the limiting shaft 21, allowing the limiting shaft 21 to translate through rotation. A baffle is also provided between the handle 26 and the bearing seat 24 to prevent the handle 26 from being inserted into the through-hole inside the bearing seat 24.

[0024] A groove is provided on the right side of the bearing seat 24, and a bushing assembly is provided in the groove. The bushing assembly includes a nylon bushing 23 and a connecting pipe 22. The nylon bushing 23 is placed on the lower layer, with its left end abutting against the inner wall of the left side of the groove, and a spring is provided on its right end. One end of the spring abuts against the nylon bushing 23, and the other end abuts against the limiting shaft 21. The connecting pipe 22 is placed on the upper layer, with its left end abutting against the side wall of the nylon bushing 23, and its right end having a second limiting tooth that cooperates with the first limiting tooth to achieve a limiting function. One end of the short shaft 31 of the handrail assembly 3 is fixedly connected to the connecting pipe 22 to drive the handrail assembly 3 to rotate.

[0025] Working principle:

[0026] When locked, the handle 26 is in a tightened state, the spring is in a compressed state, the first limiting tooth on the limiting shaft 21 meshes with the second limiting tooth on the connecting tube 22, restricting the rotation of the connecting tube 22, thereby restricting the rotation of the handrail assembly 3. At this time, the position of the handrail assembly 3 is fixed.

[0027] When the armrest assembly 3 needs to be adjusted, loosen the handle 26 to release the elastic potential energy of the spring, causing the limiting shaft 21 to move to the right, thereby separating the first limiting tooth from the second limiting tooth, thus releasing the fiber action of the connecting pipe 22. At this time, the armrest assembly 3 can be rotated 360° to adjust the height of the armrest assembly 3, so as to meet the usage needs of people of different heights.

[0028] This invention connects the handrail and the fixing mechanism through an adjustment mechanism, which allows the handrail to be locked at any angle within 360°. This enables the adjustment of the handrail height to suit children or shorter patients, providing auxiliary training for people of different heights. Furthermore, by setting a limiting shaft within the bearing seat, and through the interaction between the limiting teeth on the limiting shaft and the limiting teeth on the bushing assembly on the bearing seat, the rotation of the bushing assembly can be restricted or released via the limiting shaft. The adjustment method is simple and highly efficient.
