DETAILED DESCRIPTION

[0024] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-Figure 6 As shown, the embodiment of the utility model provides a lower limb walking auxiliary support for the elderly, comprising:

[0026] A base 1, support plates 2 are fixedly provided on both sides of the base 1, universal wheels 3 are fixedly provided at both ends of the bottoms of the two support plates 2, a sleeve 4 is fixedly provided on the base 1, a U-shaped frame 5 is provided on the upper end of the sleeve 4, and handrails 6 are provided below both ends of the U-shaped frame 5. Two connecting columns 7 are fixedly provided in parallel on the two handrails 6, and the tops of the four connecting columns 7 are respectively fixedly provided at the bottoms of both ends of the U-shaped frame 5, and the two handrails 6 are fixedly provided with anti-slip rubber sleeves for users to hold, and the bottoms of the four connecting columns 7 are tilted outwards for users to hold up, and both ends of the U-shaped frame 5 are fixedly provided with foam protective sleeves 8 to protect the user's armpits, and the four connecting columns 7 are respectively fixed through the foam protective sleeves 8 on the same side, and an adjustment component is provided between the U-shaped frame 5 and the sleeve 4;

[0027] The adjustment component includes a telescopic column 19, a second spring 20 and a positioning column 24. The telescopic column 19 is slidably arranged in the sleeve 4, the second spring 20 is fixedly arranged at the inner bottom of the sleeve 4, and the other end of the second spring 20 is fixedly arranged at the bottom of the telescopic column 19. The second spring 20 can tighten the telescopic column 19 to prevent the telescopic column 19 from loosening and falling off. The positioning column 24 is fixedly arranged on the telescopic column 19. A plurality of positioning grooves 21 are linearly penetrated on the sleeve 4. The positioning column 24 is movably arranged through one of the positioning grooves 21. An adjusting groove 23 is penetrated on the sleeve 4. The adjusting groove 23 is cooperated with the positioning column 24 so that the positioning column 24 can slide up and down in the adjusting groove 23. A connecting groove 22 is arranged on one side of the plurality of positioning grooves 21. The plurality of connecting grooves 22 are cooperated with the positioning column 24 so that the positioning column 24 can slide in the plurality of connecting grooves 22. The plurality of connecting grooves 22 are like Figure 6 The through adjustment slot 23 is provided as shown;

[0028] The fixing assembly includes an axle 9, a positioning plate 10, a rubber strip 11, a moving column 12, a pedal 13, a first spring 14 and a pull rope 15. Two fixed blocks are fixedly arranged at the bottom of the base 1 in parallel. The axle 9 is rotatably arranged on the inner side of the two fixed blocks. The axle 9 passes through one end of the positioning plate 10 and is fixedly arranged. The rubber strip 11 is fixedly arranged at the bottom of the positioning plate 10. A slide groove is penetrated on the base 1. The moving column 12 passes through the slide groove and slides. The moving column 12 slides against the inner wall of the slide groove, so that the moving column 12 can only slide up and down in the slide groove and cannot rotate. The pedal 13 is fixedly arranged on the moving column 12. A limit plate is fixedly arranged at the top of the moving column 12 and the bottom of the moving column 12. The two ends of the first spring 14 are respectively fixedly arranged at the top of the limit plate and the bottom of the base 1. The first spring 14 can drive the moving column 12 to move upward and reset, so that the user only needs to lift the pedal 13 with a light force to separate the clamping column 16 from the clamping hole 18, thereby avoiding the situation that the user cannot lift the positioning plate 10 due to the weakness of the legs, thereby increasing the practicality. The pull rope 15 is fixedly arranged at the bottom of the limit plate, and the other end of the pull rope 15 is fixedly arranged on the positioning plate 10. The pull rope 15 can drive one end of the positioning plate 10 to rotate upward;

[0029] A buckle assembly is provided on one side of the movable column 12, and the buckle assembly includes a clamping column 16 and a third spring 17. A clamping groove is provided on one side of the movable column 12, and the clamping column 16 is slidably set in the clamping groove. The third spring 17 is fixedly set at the bottom of the clamping groove, and the other end of the third spring 17 is fixedly set on the inner side of the clamping column 16. The third spring 17 can drive the clamping column 16 to reset. A clamping hole 18 is provided in the slide groove. The outer end of the clamping column 16 is hemispherical, and the clamping hole 18 is smaller than the hemispherical setting. The clamping column 16 and the clamping hole 18 are matched to be arranged so that the clamping column 16 can be clamped into the clamping hole 18, and the clamping hole 18 can squeeze the spherical surface of the clamping column 16 to push the clamping column 16 into the clamping groove.

[0030] The detailed working process of the utility model is as follows:

[0031] 1. When in use, the user can place the armpits on both ends of the U-shaped frame 5, and then hold the handrails 6 on the same side with both hands, so that the user can walk on a flat road. When encountering an uphill slope, the user steps on the pedal 13 to drive the movable column 12 to move downward, and the movable column 12 drives the clamping column 16 to move downward, so that the base 1 squeezes the spherical surface of the clamping column 16 and pushes the clamping column 16 into the clamping slot. When the clamping column 16 moves to the front of the clamping hole 18, it is reset under the action of the third spring 17 and clamped into the clamping hole 18, so that the movable column 12 can be fixed;

[0032] 2. At the same time, the moving column 12 moves downward, loosening the positioning plate 10, so that the positioning plate 10 rotates downward under the action of its own gravity, driving the rubber strip 11 to resist the ground. When going uphill, the ground can be resisted, so that the bracket cannot move backward and can only move forward, so that the user can use the force to complete the uphill walking;

[0033] 3. After going uphill, the user lifts the pedal 13 with his foot, driving the movable column 12 to move upward, so that the clamping hole 18 squeezes the spherical surface of the clamping column 16, pushing the clamping column 16 into the clamping slot, and separating the clamping column 16 from the clamping hole 18. At this time, the movable column 12 is reset upward under the action of the first spring 14, and the positioning plate 10 is pulled upward and rotated by the pull rope 15, so that the rubber strip 11 is separated from the ground, and walking on a flat road can be carried out.

[0034] 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.
