Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0033] In the above description of the utility model, it should be noted that the terms "one side", "the other side", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0034] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0035] See also Figure 1-6 The utility model provides a technical solution: a cane for preventing falling, comprising a cane shaft 11 and a handle 12 arranged at the top of the cane shaft 11, wherein the cane shaft 11 is a hollow structure and has an opening at the lower end, and a flexible film 13 is arranged at the lower end of the cane shaft 11, and the edge of the flexible film 13 is connected to the edge of the opening;

[0036] An elastic support component is disposed in the rod 11 , and the lower end of the elastic support component is connected to the middle of the flexible membrane 13 . When the elastic support component is in a naturally stretched state, the middle of the flexible membrane 13 is in a bulging state outward from the rod 11 .

[0037] When the elastic support assembly is in a freely extended state, that is, when it is not in contact with the ground, the flexible membrane 13 is in a state where the middle part is convex downward. When the lower end of the stick 11 touches the ground and applies pressure to the flexible membrane 13, the middle part of the flexible membrane 13 will first contact the ground, pushing the elastic support assembly, so that the elastic support assembly is retracted into the stick 11 until the edge of the opening of the stick 11 contacts the ground, that is, the edge of the flexible membrane 13 contacts the ground.

[0038] During use, when the pole 11 is pressed down, the flexible membrane 13 first contacts the ground with the middle part during the gradual contraction of the elastic support assembly, and then becomes flat, which can discharge the air between the flexible membrane 13 and the smooth ground, and play an adsorption role between the pole 11 and the smooth ground, thereby improving the stability of the support;

[0039] When the pole 11 is lifted, the middle of the flexible membrane 13 is supported by the elastic support assembly and will remain in contact with the ground. The edge of the flexible membrane 13 will be separated from the ground first along with the lifting of the pole 11, thus destroying the adsorption state between the flexible membrane 13 and the smooth ground.

[0040] That is, when the pole 11 is pressed down to touch the ground, an adsorption fixing state can be formed between the lower end of the pole 11 and the smooth ground, thereby improving the supporting effect of the pole 11 on the smooth bottom surface, and the adsorption fixing state is automatically cancelled when the pole 11 is lifted up, which is convenient for use.

[0041] In this embodiment, a conical sleeve 131 is provided at the lower end of the stick 11 , one end of the conical sleeve 131 is detachably connected to the lower end of the stick 11 , and the other end of the conical sleeve 131 is fixedly connected to the edge of the flexible membrane 13 .

[0042] The flexible membrane 13 is disc-shaped. By sticking the edge of the flexible membrane 13 on the bottom surface of the conical sleeve 131, the edge of the flexible membrane 13 is supported, so as to facilitate the simultaneous contact of the bottom edge of the flexible membrane 13 with the ground, thereby promoting the discharge of air between the bottom surface of the flexible membrane 13 and the ground; at the same time, the outer surface of the lower end of the pole 11 is provided with an external thread, and the conical sleeve 131 is sleeved on the outside of the lower end of the pole 11 and connected by threaded fitting. By bonding the flexible membrane 13 to the conical sleeve 131, the conical sleeve 131 can be removed to inspect and replace the flexible membrane 13.

[0043] In this embodiment, the elastic support assembly includes a movable column 21 and a spring 33 disposed in the rod 11. One end of the movable column 21 is detachably connected to the middle of the flexible membrane 13, and the other end of the movable column 21 is inserted into the rod 11 and slidably cooperates with the rod 11.

[0044] One end of the spring 33 is fixedly connected to the end of the movable column 21 inserted into the rod 11 , and the other end of the spring 33 is fixedly connected to the side surface of the rod 11 facing away from the opening.

[0045] When in use, the stick 11 is pressed downward, and the middle part of the flexible membrane 13 is pushed by the movable column 21 to contact the ground. Under the joint action of the stick 11 and the movable column 21, the spring 33 is deformed and contracted, so that the stick 11 moves downward, and then the conical sleeve 131 pushes the edge of the flexible membrane 13 closer to the ground. After the bottom surface of the flexible membrane 13 is completely in contact with the ground, the lower end of the conical sleeve 131 contacts the ground through the flexible membrane 13 to provide auxiliary support for the patient.

[0046] In this embodiment, a connector 132 is fixedly connected to the middle of the flexible membrane 13, and a threaded hole 133 penetrating the flexible membrane 13 is formed on the connector 132;

[0047] The movable column 21 is a hollow structure with two ends open. The end of the movable column 21 facing the flexible membrane 13 is inserted into the threaded hole 133 and connected by threaded fitting. A piston 211 is sealed and slidably fitted inside the movable column 21.

[0048] A push rod 212 is disposed above the piston 211 , one end of the push rod 212 is fixedly connected to the top wall of the piston 211 , and the other end of the push rod 212 is fixedly connected to a side surface of the rod 11 facing away from the opening.

[0049] When the stick 11 is squeezed, the spring 33 is squeezed and contracted, and then the piston 211 slides downward in the movable column 21 to push the air in the movable column 21 to overflow from the bottom surface of the flexible membrane 13. After the pressure on the stick 11 is released, the bottom surface of the flexible membrane 13 is completely in contact with the ground, so that a closed chamber is formed between the piston 211 and the flexible membrane 13 in the movable column 21. The spring 33 deforms and stretches to push the stick 11 away from the movable column 21, so that the piston 211 slides upward in the movable column 21, increasing the volume of the closed chamber, thereby generating negative pressure in the closed chamber, increasing the adsorption force between the flexible membrane 13 and the ground, and further enhancing the anti-slip effect of the walking stick.

[0050] In this embodiment, an auxiliary support rod 31 is disposed outside the stick 11 , and the auxiliary support rod 31 is connected to the outer wall of the stick 11 .

[0051] An auxiliary support rod 31 is provided outside the stick 11 to increase the support points of the stick; a plurality of auxiliary support rods 31 are provided, and the plurality of auxiliary support rods 31 are arranged in a circular array with the stick 11 as the center to disperse the pressure applied by the patient in multiple directions, thereby reducing the risk of the stick slipping.

[0052] In this embodiment, the outer wall of the stick 11 is provided with a storage groove 111 along the length direction, one end of the auxiliary support rod 31 is hinged to the upper side wall of the storage groove 111, and the rotation trajectory plane of the auxiliary support rod 31 is parallel to the stick 11.

[0053] There are multiple storage grooves 111, which are opposite to the multiple auxiliary support rods 31 one by one. By hingedly connecting one end of the auxiliary support rod 31 to the upper side wall of the storage groove 111, the auxiliary support rod 31 can be stored in the storage groove 111, reducing the volume of the cane when idle, making it easier to move or store.

[0054] In this embodiment, a through hole 112 penetrating the outer wall of the stick 11 is formed on a side of the storage slot 111 facing the movable column 21, and a second connecting rod 32 is disposed in the through hole 112;

[0055] One end of the second connecting rod 32 extends toward the auxiliary support rod 31 and is hinged to the middle of the auxiliary support rod 31 . The other end of the second connecting rod 32 passes through the through hole 112 and extends into the rod 11 and is hinged to the side wall of the movable column 21 . The rotation trajectory plane of the second connecting rod 32 is coplanar with the rotation trajectory plane of the auxiliary support rod 31 .

[0056] The rotation of the auxiliary support rod 31 and the sliding of the movable column 21 are linked by the second connecting rod 32 to facilitate the control of the retraction and extension of the auxiliary support rod 31; Figure 1, the auxiliary support rod 31 moves out of the storage slot 111 to be in an unfolded state, and because the cane rod 11 is subjected to pressure applied by the patient, the movable column 21 slides relatively into the cane rod 11, and the movable column 21 pushes the second connecting rod 32 to rotate forward during the sliding process, and then the second connecting rod 32 pushes the auxiliary support rod 31 to move out of the storage slot 111, so that the auxiliary support rod 31 rotates and unfolds; Figure 6 The auxiliary support rod 31 is embedded in the storage groove 111 and is in a folded state. Since the stick rod 11 loses the pressure applied by the patient, the movable column 21 slides outward from the stick rod 11, and then the second connecting rod 32 rotates in the opposite direction, driving the auxiliary support rod 31 to rotate and embed into the storage groove 111, and finally achieving the purpose of automatic folding and unfolding.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
