Description

Technical Field

[0001] This utility model relates to the field of walking aid technology, and in particular to a walking aid for rehabilitation and nursing care of neurological patients. Background Technology

[0002] A walking frame is a device that assists patients with certain neurological disorders to walk. It helps patients with weak lower limbs or limited walking function to practice walking, enabling them to take steps and gradually regain their walking ability, thus promoting motor function rehabilitation. For example, Parkinson's disease patients can improve problems such as difficulty walking and gait abnormalities by using a walking frame.

[0003] Walking frames provide stable support for patients, allowing them to maintain balance when standing and walking. However, existing walking frames have shortcomings in use. The friction between the wheels and the ground is too small, and there is almost no additional resistance. Some patients find it too easy to push the walking frame, and their muscles do not receive sufficient stimulation, thus failing to achieve the desired exercise effect. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the above-mentioned problems with the rehabilitation and nursing walking frame for neurological patients, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rehabilitation nursing walking frame for neurological patients, including a frame body, on which four walking wheels are mounted and rotatably connected to the frame body via rotating shafts;

[0007] It also includes four brake covers fixed on the frame and coaxial with the corresponding rotating shaft. A rotating disk is fixedly connected to the rotating shaft and the rotating disk is located inside the corresponding brake cover. At least two counterweights are hinged to the outside of the rotating disk, and a spring is elastically connected between the counterweights and the rotating disk. The counterweights are controlled by the centrifugal force of the auxiliary wheel to rotate in the direction of the brake cover with the hinge point as the center.

[0008] As a preferred embodiment of the rehabilitation and nursing assistive frame for neurological patients described in this utility model, the inner wall of the braking cover is provided with a friction ring, and the inner wall of the friction ring is provided with grooves at equal intervals.

[0009] As a preferred embodiment of the rehabilitation and nursing walking frame for neurological patients described in this utility model, the counterweight has an irregular arc shape, and when the counterweight contacts the inner wall of the friction ring, the irregular arc surface of the counterweight matches the shape of the inner wall of the friction ring.

[0010] As a preferred embodiment of the rehabilitation and nursing walking frame for neurological patients described in this utility model, the counterweight block has a plurality of raised strips on its arc-shaped surface that match the size of the groove.

[0011] As a preferred embodiment of the rehabilitation and nursing assistive frame for neurological patients described in this utility model, the number of counterweights is four, and they are distributed equidistantly around the outside of the rotating disk.

[0012] As a preferred embodiment of the rehabilitation and nursing assistive frame for neurological patients described in this utility model, the surface of the rotating disk is provided with multiple weight-reducing holes.

[0013] The beneficial effects of this invention are as follows: the counterweight can contact the friction ring when the walking wheel rotates at a high speed to provide resistance. The appropriate resistance can effectively exercise the patient's muscle strength, enhance joint stability, and improve the patient's motor control and balance. In addition, the resistance generated when the walking wheel rotates can prevent the walking frame from moving too fast, effectively preventing the patient from falling due to poor control of the movement speed.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0024] Reference Figures 1-4 As an embodiment of the present utility model, a rehabilitation nursing walking frame for neurological patients is provided, which includes a frame body 1 and four walking wheels 2 mounted on the frame body 1 through a rotating shaft 21 and rotatably connected to the frame body 1.

[0025] It also includes four brake covers 3 fixed on the frame 1 and coaxial with the corresponding rotating shaft 21. The inner wall of the brake cover 3 is provided with friction rings 4, and the inner wall of the friction rings 4 is provided with grooves at equal intervals. The friction rings 4 are made of rubber to increase the friction with the counterweights 6. A rotating disk 5 is fixedly connected to the rotating shaft 21. The surface of the rotating disk 5 is provided with multiple weight-reducing holes to reduce the weight of the rotating disk 5 and reduce the moving mass of the walking wheel 2. The rotating disk 5 is located inside the corresponding brake cover 3. At least two counterweights 6 are hinged to the outside of the rotating disk 5, and springs 7 are elastically connected between the counterweights 6 and the rotating disk 5. The counterweights 6 are controlled by the centrifugal force of the rotating walking wheel 2 to rotate in the direction of the brake cover 3 with the hinge point as the center. When some patients use it, because their own walking speed is slow, the rotation speed of the walking wheel 2 is also slow. At this time, the counterweights 6 will not contact the friction rings 4.

[0026] like Figure 4As shown, there are four counterweights 6, which are distributed equidistantly around the outside of the rotating disk 5. The arc-shaped surface of the counterweights 6 is provided with several protrusions that match the size of the groove. The counterweights 6 are irregular arc-shaped. When the counterweights 6 are in contact with the inner wall of the friction ring 4, the irregular arc-shaped surface of the counterweights 6 matches the shape of the inner wall of the friction ring 4. The protrusions will cooperate with the groove to provide travel resistance as the auxiliary wheel 2 rotates.

[0027] According to the centrifugal force formula: Fc (centrifugal force of the walking wheel 2) = m (mass of the counterweight 6) · r (distance from the center of gravity of the counterweight 6 to the shaft 21) · ω (rotational angular velocity) 2 and ω = v (linear velocity) / r, when the centrifugal force Fc is equal to the preload force Fs of the spring 7, the counterweight 6 begins to move. By adjusting m, r and Fs, the speed limit threshold of the walking wheel 2 can be set. When the walking wheel 2 reaches the speed limit threshold, the counterweight 6 and the friction ring 4 squeeze together to generate resistance, which effectively exercises the patient's muscle strength, enhances joint stability, and improves the patient's motor control and balance.

[0028] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
