Description

Technical Field

[0001] The utility model relates to the technical field of walking assistive devices, and more specifically to a navigation crutch with an adjustable operating panel angle. Background Art

[0002] A cane is a simple device that assists walking. It is used to help people with limited mobility to walk and prevent falls. With the development of technology, the functions of canes are becoming more and more diverse. In particular, navigation components are installed on canes, which can remind elderly people with cognitive impairment of obstacles on their way, thereby reducing the occurrence of accidents.

[0003] Based on the above, the inventors found that: the existing navigation crutches mainly have two support methods at the bottom: plane support and roller support. However, the crutches with plane support need to be picked up and put down each time they are used, which is not suitable for elderly people with cognitive impairment who have poor physical strength. Although the crutches with roller support can walk close to the ground, they are not as stable as the crutches with plane support when encountering poor road conditions. Therefore, in view of this, the existing structure is studied and improved, and a navigation crutch with an adjustable operating panel angle is provided, in order to achieve a more practical purpose.

[0039] Example:

[0040] See also Figure 1-5 A navigation crutch with an adjustable operating panel angle comprises a crutch 1, a navigator 2 is fixedly connected to the upper part of the crutch 1, and a base 3 is fixedly connected to the bottom end of the crutch 1, a quick positioning mechanism 4 is arranged in the middle of the base 3, and a pair of support rods 5 are arranged on both sides of the base 3, and a flat plate 6 and a roller 7 are arranged at both ends of the support rods 5, and the opposite surfaces of the two support rods 5 located in the same front-to-back direction are centrally fixedly connected with a same connecting rod 8, and two limit rings 9 are fixedly connected to the outer side of the connecting rod 8;

[0041] The quick positioning mechanism 4 includes a screw rod 10, two ball sliders 11 are sleeved on the outer side of the screw rod 10, a connecting plate 12 is fixedly connected to the outer side of the ball slider 11, and positioning rods 13 are fixedly connected to the inner side of the connecting plate 12 at four top corners. In order to facilitate the rapid adjustment of the flat plate 6 and the roller 7 to adapt to different road conditions, a quick positioning mechanism 4 is provided.

[0042] See also Figure 1 A navigation probe is fixedly connected to the front end of the navigator 2, and an operation panel is provided on one side of the navigator 2. A gooseneck is fixedly connected to the connection between the navigator 2 and the operation panel, and navigation prompts are provided through the navigator 2.

[0043] See also Figure 3 The connecting rod 8 is located inside the base 3, and the connecting rod 8 is movably connected to the base 3. The user holds the top of the turning rod 1 for mobile support. When the road condition is poor, the flat plate 6 faces downward and fits the ground. When the road condition is good, the support rod 5 is rotated, and the connecting rod 8 and the limit ring 9 are driven to rotate synchronously, so that the roller 7 faces downward and contacts the ground.

[0044] See also Figure 4 Two positioning holes are arranged through the interior of the limiting ring 9, and the two positioning holes are arranged vertically and crosswise, so that the rotation stability of the connecting rod 8 and the supporting rod 5 is ensured by the limiting ring 9.

[0045] See also Figure 5 The screw rod 10 passes through the middle of the base 3 and is movably connected to the base 3. The top of the screw rod 10 is rotated to drive the ball slider 11 to move.

[0046] See also Figure 5 The outer surface of the screw rod 10 is provided with two rotating threads of the same length and opposite directions, and the two rotating threads are respectively matched with the two ball sliders 11. Since the two rotating threads are of the same length and opposite directions, the two ball sliders 11 respectively drive the corresponding connecting plates 12 to move in opposite directions synchronously.

[0047] See also Figure 5 The two connecting plates 12 are symmetrically arranged, and the positioning rod 13 passes through the base 3 and is adapted to the limiting ring 9.
