[0031] Reference Figure 2 , Figure 3 and Figure 4 The utility model provides an embodiment: a device for preventing the elderly from falling and assisting them to stand up after falling, comprising a U-shaped base 1, a placement groove 3 is provided on the front and rear sides of the top of the U-shaped base 1, a ball 4 is rotatably connected to the left side of the placement groove 3, a bolt 5 is threadedly connected to the front and rear sides of the U-shaped base 1, one end of the bolt 5 passes through the placement groove 3 and the ball 4 in sequence, a hollow rod 6 is fixedly connected to the top of the ball 4, a servo motor 7 is fixedly connected to the bottom of the inner side of the front hollow rod 6, a threaded rod 8 is fixedly connected to the output end of the servo motor 7, a movable rod 9 is threadedly connected to the outer side of the threaded rod 8, a sliding rod 10 is arranged inside the rear hollow rod 6, an open groove 17 is provided on the adjacent sides of the two hollow rods 6, and the adjacent ends of the movable rod 9 and the sliding rod 10 are A movable shaft 11 is rotatably connected, one end of the two movable shafts 11 respectively penetrates the corresponding open grooves 17, a cylindrical gear 12 is fixedly connected to the outer side of the front movable shaft 11, a fixed plate 13 is fixedly connected to the rear side of the movable rod 9, a T-bar 14 is arranged on the top of the fixed plate 13, the middle and lower part of the T-bar 14 penetrates the fixed plate 13 and is fixedly connected to a gear ring 15, the gear ring 15 is meshed and connected with the cylindrical gear 12, a spring 16 is arranged on the outer side of the T-bar 14, one end of the spring 16 is fixedly connected to the top of the fixed plate 13, and the other end of the spring 16 is fixedly connected to the inner top of the T-bar 14, a limiting mechanism 2 is arranged on the adjacent side of the two movable shafts 11, and the sizes of the two hollow rods 6 match the internal sizes of the corresponding placement slots 3 respectively;

[0032] Specifically, first pull the T-bar 14 upward to drive the gear ring 15 to disengage from the cylindrical gear 12. The importance of this step lies in that it releases the limit on the movable shaft 11, allowing the hollow frame 201 to be transformed into a state perpendicular to the ground. After completing the above operations, loosen the T-bar 14. At this time, the spring 16 will play its role and drive the T-bar 14 to rebound to its original state through its own elastic potential energy. At the same time, the gear ring 15 will also return to its original state to limit the cylindrical gear 12. The purpose of this step is to prevent the movable shaft 11 from shaking at will during the storage process and affecting the normal storage work. Next, loosen the bolts 5 on both sides to release the limit on the ball 4. At this time, the user can rotate the ball 4 to allow the hollow rod 6 to smoothly enter the placement slot 3. Finally, tighten the bolt 5 to complete the entire storage process, which not only saves space, but also improves the storage efficiency, thereby improving the practicality of the device.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The limiting mechanism 2 includes a hollow frame 201, the front and rear sides of the hollow frame 201 are respectively fixedly connected to the adjacent ends of the two movable shafts 11, the inside of the hollow frame 201 is rotatably connected with a bidirectional screw rod 202, the middle part of the outer side of the bidirectional screw rod 202, and the top of the hollow frame 201 is rotatably connected with a rotating rod 204, the bottom end of the rotating rod 204 passes through the hollow frame 201 and is fixedly connected with an active bevel gear 205, the active bevel gear 205 is meshed and connected with the driven bevel gear 203, the left and right sides of the outer wall of the bidirectional screw rod 202 are both threadedly connected with movable plates 206, the adjacent sides of the two movable plates 206 are fixedly connected with a body binding belt 207, the two movable plates 206 are both slidably connected inside the hollow frame 201, and the tops of the two movable plates 206 are both fixedly connected with handrails 208;

[0034] Specifically, when the user rotates the rotating rod 204, the active bevel gear 205 will rotate easily accordingly. Due to the precise meshing of the driven bevel gear 203 and the active bevel gear 205, the driven bevel gear 203 can also follow the rotation of the active bevel gear 205 and operate smoothly. At this time, the two-way screw rod 202 will rotate accordingly, thereby driving the movable plates 206 on both sides to move toward the middle. This design fully takes into account the needs of users of different body shapes, so that no matter whether the user is thin or obese, they can find a gripping position that suits them. The user can then fix the body strap 207 on the body to further increase their walking stability.

[0035] Reference Figure 3 and Figure 5 The left and right sides of the two hollow rods 6 are provided with slide grooves 19, and the left and right sides of the movable rod 9 and the slide rod 10 are fixedly connected with sliders 18, and the sliders 18 are slidably connected with the corresponding slide grooves 19 respectively;

[0036] Specifically, the sliding groove 19 can limit the moving track of the movable rod 9 so that it can move more smoothly.

[0037] Reference Figure 2 and Figure 3 A switch 20 is fixedly connected to the top front side of the hollow frame 201, and the switch 20 is electrically connected to the servo motor 7. A protective cover 21 is arranged on the outside of the switch 20, and the top left side of the protective cover 21 is rotatably connected to the top of the hollow frame 201 through a rotating shaft;

[0038] Specifically, the operation of the servo motor 7 can be controlled by the switch 20 , and the protective cover 21 can protect the switch 20 from being damaged by external factors.

[0039] Reference Figure 1 , universal wheels 22 are fixedly connected to the four corners of the bottom of the U-shaped base 1;

[0040] Specifically, the device can be easily moved by the universal wheels 22 .

[0041] Working principle: when the device is finished using, first pull the T-bar 14 upwards to drive the gear ring 15 to disengage from the cylindrical gear 12, thereby releasing the limit on the movable shaft 11. At this time, turn the hollow frame 201 to be vertical to the ground, and then release the T-bar 14. At this time, the spring 16 will drive the T-bar 14 to rebound to its original state through its own elastic potential energy, and the gear ring 15 will then return to its original state to limit the cylindrical gear 12, thereby preventing the movable shaft 11 from shaking at will and affecting the normal storage work. At this time, loosen the bolts 5 on both sides to release the limit on the ball 4, and then rotate the ball 4 to make the hollow rod 6 enter the placement groove 3. Finally, tighten the bolts 5 to complete the storage work, which can reduce the space occupied by the device, thereby meeting the needs of users, and users can use the device When walking, by rotating the rotating rod 204, the active bevel gear 205 on the rotating rod 204 will rotate accordingly, and the driven bevel gear 203 will also rotate due to the engagement with the active bevel gear 205, thereby driving the movable plates 206 on both sides to move toward the middle, which can facilitate people of different body shapes to grasp the handrails 208 on both sides, and the stability of the user can be further improved by the body straps 207. When people of different heights need to use it, they only need to drive the threaded rod 8 to rotate through the servo motor 7, and the movable rod 9 on the threaded rod 8 will move upward in the slide groove 19. At this time, the hollow frame 201 will also move until the user can grasp the handrail 208. The device can be adapted to patients of different heights and body shapes, thereby reducing the cost of use and improving the practicality of the device.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
