detailed description

As shown in Figures 1 to 3, the bottom of the crutch body 1 is a tapered foot 11, and the tip of the foot is facing upwards. There is a large contact area between the foot and the ground, and the foot may include a layer of rubber , to play the role and effect of shock absorption. A base 2 is fixed on the feet, the base is a truncated metal piece, and the base can also be made of composite materials. The large end of the base is open, and the large end of the base is close to the end where the handle of the main body of the crutch is located. The setting of the opening makes the large end of the base form a groove, and the shape of the groove is the same as the shape of the base. The seal between the base and the feet is good, and the base can be used as a container for feeding water to pets. When the elderly go out for a long time and carry pets, drinking water can be poured on the large end of the base, and the pets can drink water. The edge of the base is provided with a number of lightening holes 21. Under the premise of ensuring the strength of the base, the setting of the lightening holes can reduce the weight of the base, and the shape of the lightening holes is not limited. As shown in Figure 4 and Figure 5, a fixed rod 4 is provided between each two adjacent weight-reducing holes, the fixed rod is a cylindrical metal rod or a rod made of composite material, and the fixed rod is arranged in the base And several fixed rods are evenly arranged along the circumferential direction, and a first extension rod 5 can be drawn in the inner cavity of each fixed rod. The first extension rod is a cylindrical metal rod or a rod made of composite material. . A second extension rod 6 can be drawn in the inner chamber of the first extension rod. The second extension rod is a cylindrical metal rod or a rod made of composite material. The length of the second extension rod is slightly longer than that of the first extension rod. The length of the first extension rod is so as to hold the second extension rod to facilitate the drawing and pulling of the second extension rod in the first extension rod. The length of the first extension rod is slightly longer than the length of the fixed rod, so as to facilitate holding the first extension rod to facilitate the pulling of the first extension rod in the fixed rod.

As shown in Figure 3, a storage box 3 is provided in the middle of the crutch main body, the storage box is a plastic box, the storage box is covered with the outside of the crutch main body, and a storage cavity 31 is provided on the storage box. An umbrella surface 7 is placed in the cavity. The umbrella cover is made of cloth with waterproof function, and after the umbrella cover is unfolded, the umbrella cover forms a hollow circular truncated shape. Several snap buttons are arranged on the inner wall of the umbrella surface, and the several snap buttons are respectively located on several straight lines, and the number of the straight lines is the same as the number of the first extension rods. The snap buttons on each straight line correspond to the corresponding first extension rods and second extension rods, and slots are respectively arranged on the first extension rods and the second extension rods that cooperate with each other, and the slots are matched with the corresponding snap buttons .

As shown in Figure 6 and Figure 7, when encountering rainy weather outdoors, the crutches can be turned over so that the feet of the main body of the crutches face upward, and the second extension rod is pulled out from the first extension rod, and the first extension rod The rod is withdrawn from the fixed rod. Take out the umbrella from the storage box, unfold the umbrella, and fasten the snap buttons on the umbrella into the slots corresponding to the first extension rod and the second extension rod. Because the shape of the umbrella surface after unfolding is a truncated cone shape, the first extension rod, the second extension rod and the base form a truncated cone shape, so the umbrella surface can be in good contact with the base, the first extension rod and the second extension rod. In order to prevent rainwater from flowing down through the gap between the umbrella surface and the base, an annular groove is provided on the outer wall of the base, as shown in Figure 8, an annular clip 8 is placed in the annular groove, and the small end of the umbrella surface can be placed on the and cover the annular groove, then insert the ring card into the annular groove, and the ring card will squeeze and fix the umbrella surface. At this moment, the rainwater falling from above just flows down along the outer surface of the umbrella surface, and can not flow down from the gap between the umbrella surface and the base.

The crutches are the same as ordinary crutches when assisting the elderly to walk. When the old man sits down, due to the setting of the base, the main body of the crutch will not be tilted, which avoids the potential safety hazard when the old man bends down to pick up the main body of the crutch. When encountering a rainy day, the umbrella cover in the storage box is taken out and buckled on the base, the first extension rod and the second extension rod to be used as an umbrella. In order to ensure that the main body of the crutch will not fall by itself, the small end surface of the base is higher than the bottom surface of the main body of the crutch by a section, and the distance between the small end surface of the base and the bottom surface of the main body of the crutch is 5mm-15mm, and the preferred distance is 10mm. In this way, the bottom of the base and the main body of the crutch can be in contact with the ground at the same time, and the crutch will not be tilted.
