Description

Technical Field

[0001] This utility model relates to the field of walking aids, and in particular to a walking aid. Background Technology

[0002] A walking aid is an assistive device used to help people with mobility impairments walk. Walking aids can provide additional support and stability, help users maintain their balance, and reduce the risk of falls.

[0003] In order to ensure stability during use, traditional walking aids are fixed to the legs and frame by welding, which makes them unadjustable, limiting their applicability. They also take up space when stored, causing inconvenience. Utility Model Content

[0004] The technical problem this utility model aims to solve is that, in order to ensure stability during use, the legs and frame of traditional walking aids are fixed by welding, making them unadjustable and limiting their applicability. Furthermore, they take up space when stored, leading to inconvenience.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a walking aid, including a first adjusting frame, a second adjusting frame, two first threaded ring blocks, four second threaded ring blocks, four support legs, and two locking rods. Both ends of the first adjusting frame are fixedly connected to first grooved threaded blocks. Both ends of the second adjusting frame pass through the inner walls of the two first grooved threaded blocks and are slidably connected to the inner walls of both ends of the first adjusting frame. The inner wall of the first threaded ring block is threadedly connected to the outer surface of the first grooved threaded block. The inner wall of the first threaded ring block is sleeved and connected to the outer surface of the second adjusting frame. A first locking hole block is fixedly connected to the outer surface of one end of both the first and second adjusting frames. The inner walls of one end of the first and second adjusting frames are rotatably connected to brackets. The outer surface of one end of the bracket is fixedly connected to a second locking block. One end of the locking rod is inserted into the inner walls of the first and second locking blocks. A crossbeam is fixedly connected between the two ends of the bracket. A second grooved threaded block is fixedly connected to one side of each end of the crossbeam. The inner wall of the second threaded ring block is threadedly connected to the outer surface of the second grooved threaded block. One end of each of the four support legs is inserted into the inner walls of the two ends of the crossbeam and the four second grooved threaded blocks. The inner wall of one end of the second threaded ring block is sleeved and connected to one end of the support leg. Rollers are rotatably connected to the outer surface of one end of each of the two support legs.

[0006] The aforementioned components achieve the following effect: When using the walking aid to assist people with mobility impairments to walk, the four outriggers can be inserted into the inner walls of the four second grooved threaded blocks and the inner walls of both ends of the two crossbars. Then, the second threaded ring block is slid onto the outrigger to a certain position, and one end of its inner wall is screwed onto the outer surface of the second grooved threaded block. Since one end of both the first and second threaded ring blocks is conical, it can compress and shrink one end of the second grooved threaded block, fixing the outrigger to the inner wall of one end of the crossbar. Then, the two supports are rotated to a certain angle on the inner walls of one end of the first and second adjusting frames, respectively, and unfolded. This causes the second locking block to rotate on the first locking block to a certain angle, aligning the inner walls of both. At this point, the locking rod is... The first and second locking blocks are inserted into the inner walls of the locking blocks to limit and fix them. Finally, according to the user's body shape, the second adjusting frame is manually pulled to one end to a certain position in the inner wall of the first adjusting frame. Then, the first threaded ring block is slid to one end to a certain position on the outer surface of the second adjusting frame. Then, it is screwed into the outer surface of the first grooved threaded block to press it. The adjusted second adjusting frame is fixed in the inner wall of the first adjusting frame, changing the distance between the two supports to facilitate use by people of different body shapes and improve the applicability of the walking aid. Similarly, when storing, the legs can be removed and the bracket can be rotated to a certain angle and folded on one side of the first and second adjusting frames for easy storage and convenient daily use.

[0007] Preferably, a limiting device is fixedly connected to the outer surface of the crossbeam. The limiting device includes a limiting frame, a rectangular block fixedly connected to the outer surface of the crossbeam, a telescopic rod fixedly connected to one side of the rectangular block, a pull block fixedly connected to one end of the telescopic rod, a pull rope fixedly connected to one side of the pull block, a grooved rod fixedly connected to one side of the rectangular block, a sliding hole provided on the inner wall of the grooved rod, and one end of the outer surface of the limiting frame slidingly connected to the inner wall of the grooved rod and the inner wall of the sliding hole. One end of the limiting frame is fixedly connected to one end of the pull rope, a guide roller is fixedly connected to the outer surface of one end of the grooved rod, the pull rope is sleeved on the outer surface of the guide roller, and a first spring is sleeved on the outer surface of one end of the limiting frame. The two ends of the first spring are fixedly connected to the limiting frame and one side of the grooved rod, respectively.

[0008] The effect achieved by the above components is as follows: By setting the limiting device, when using the walker and only standing up, to prevent the walker from wobbling due to the roller slippage, the support can be manually held and the pull block pulled at the same time. This causes the telescopic rod to be stretched open, and then the pull rope is rotated to move to one end on the outer surface of the guide roller. The other end will pull the limiting frame to slide downward in the groove rod and the inner wall of the sliding hole, causing the first spring to stretch. This causes one end of the limiting rod to abut against the ground, increasing the contact area and resistance between the outrigger and the ground, improving the stability of the walker, preventing the roller from slipping when walking, and facilitating the use of the walker. Similarly, when using, simply release the pull block, and under the reset action of the first spring, the limiting frame can be reset and retracted, without hindering the movement of the walker.

[0009] Preferably, a bearing is fixedly connected to the outer surface of one end of the guide roller, and the outer ring of the bearing is fixedly connected to the outer surface of the grooved rod.

[0010] The effect achieved by the above components is that by setting bearings, the rotational wear between the guide roller and the groove rod can be reduced, thereby increasing the service life of the guide roller.

[0011] Preferably, the bottom of the limiting frame is fixedly connected with a plurality of anti-slip blocks, and the plurality of anti-slip blocks are arranged at equal intervals.

[0012] The effect achieved by the above components is that by setting anti-slip blocks, the contact friction at the bottom of the limit frame can be increased, making it more secure and less prone to slippage after it abuts against the ground.

[0013] Preferably, a reinforcing rod is fixedly connected to both sides of the rectangular block, and one side of the reinforcing rod is fixedly connected to the outer surface of the crossbeam.

[0014] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the rectangular block and the cross frame can be increased, making the connection more secure and less prone to breakage or damage.

[0015] Preferably, one end of the pull rope is connected through the outer surface to one side of the inner wall of the rectangular block.

[0016] The effect achieved by the above components is that by connecting the pull rope through the rectangular block, the direction of its pulling can be limited, making the use of the pull rope convenient.

[0017] Preferably, a second spring is sleeved and connected to the outer surface of the telescopic rod, and the two ends of the second spring are fixedly connected to one side of the pull block and the rectangular block, respectively.

[0018] The effect achieved by the above components is that, by setting a second spring, after the pull block is pulled, it can be driven to move back to one side of the rectangular block, assisting the first spring in the reset operation.

[0019] Preferably, a handle block is fixedly connected to one side of the pull block, and the longitudinal section of the handle block is U-shaped.

[0020] The effect achieved by the above components is that by setting a handle block, the contact area on one side of the pull block can be increased, making it easier to manually grip and hook one side, thus facilitating operation.

[0021] The beneficial effects of this utility model are:

[0022] When using a walking aid to assist people with mobility impairments to walk, first insert the four outriggers into the inner walls of the four second grooved threaded blocks and the inner walls of both ends of the two crossbars. Then, slide the second threaded ring block on the outrigger to a certain position, and screw one end of its inner wall onto the outer surface of the second grooved threaded block. Since one end of both the first and second threaded ring blocks is set in a conical column shape, one end of the second grooved threaded block can be squeezed and contracted to fix the outrigger in the inner wall of one end of the crossbar. Then, rotate the two brackets to a certain angle on the inner walls of one end of the first and second adjustment frames respectively, and unfold them. This will cause the second locking block to rotate on the first locking block to a certain angle, aligning the inner walls of the two. At this point, insert the locking rod into the first locking hole. The first adjustment bracket is fixed in place by limiting its position within the inner wall of the first adjustment bracket and the second locking block. Finally, based on the user's body shape, the second adjustment bracket is manually pulled to one end to a certain position within the inner wall of the first adjustment bracket. Then, the first threaded ring block is slid to one end to a certain position on the outer surface of the second adjustment bracket. Finally, it is screwed onto the outer surface of the first grooved threaded block to press it, thus fixing the adjusted second adjustment bracket in the inner wall of the first adjustment bracket. This changes the distance between the two brackets, making it easier for people of different body types to use and improving the applicability of the walking aid. Similarly, when storing, the legs can be removed and the bracket can be rotated to a certain angle and folded onto one side of the first and second adjustment brackets for easy storage and convenient daily use.

[0032] Figure 1-5The illustrated walking aid includes a first adjusting frame 1, a second adjusting frame 5, two first threaded ring blocks 4, four second threaded ring blocks 10, four support legs 11, and two locking rods 14. Both ends of the first adjusting frame 1 are fixedly connected to first grooved threaded blocks 3. Both ends of the second adjusting frame 5 pass through the inner walls of the two first grooved threaded blocks 3 and are slidably connected to the inner walls of both ends of the first adjusting frame 1.

The inner walls of the first threaded ring blocks 4 are sleeved and connected to the outer surfaces of the second adjusting frame 5.

One side of each end of the crossbeam 8 is fixedly connected to a second grooved threaded block 9. The inner wall of the second threaded ring block 10 is threadedly connected to the outer surface of the second grooved threaded block 9. One end of each of the four legs 11 is inserted into the two ends of the two crossbeams 8 and the inner wall of the four second grooved threaded blocks 9. One end of the inner wall of the second threaded ring block 10 is sleeved and connected to one end of the legs 11. Rollers 12 are rotatably connected to the outer surface of one end of each of the two legs 11. When using a walking aid to assist people with mobility impairments to walk, first insert the four support legs 11 into the inner walls of the four second grooved threaded blocks 9 and the inner walls of both ends of the two crossbars 8. Then, slide the second threaded ring block 10 on the support leg 11 to a certain position, and screw one end of its inner wall onto the outer surface of the second grooved threaded block 9. Since one end of the first threaded ring block 4 and the second threaded ring block 10 are both set in a conical column shape, one end of the second grooved threaded block 9 can be squeezed and contracted to fix the support leg 11 in the inner wall of one end of the crossbar 8. Then, after rotating the two brackets 7 to a certain angle on the inner walls of one end of the first adjusting frame 1 and the second adjusting frame 5 respectively, unfold them, causing the second locking block 13 to rotate on the first locking block 6 to a certain angle, so that the inner walls of the two are aligned. At this time, the locking rod 14 is inserted. The first locking block 6 and the second locking block 13 are used to limit and fix the second adjustment frame 5 in the inner wall of the first adjustment frame 1 according to the user's body shape. Then, the first threaded ring block 4 is slid to a certain position on the outer surface of the second adjustment frame 5 and screwed into the outer surface of the first grooved threaded block 3 to press it. The adjusted second adjustment frame 5 is then fixed in the inner wall of the first adjustment frame 1, changing the distance between the two supports 7 to facilitate use by people of different body shapes and improve the applicability of the walking aid. Similarly, when storing, the legs 11 can be removed and the support 7 can be rotated to a certain angle and folded on one side of the first adjustment frame 1 and the second adjustment frame 5 for easy storage and daily use.

[0033] Figure 1-5 A limiting device 2 is fixedly connected to the outer surface of the cross frame 8 shown. The limiting device 2 includes a limiting frame 27. A rectangular block 21 is fixedly connected to the outer surface of the cross frame 8. A telescopic rod 22 is fixedly connected to one side of the rectangular block 21. A pull block 23 is fixedly connected to one end of the telescopic rod 22. A pull rope 24 is fixedly connected to one side of the pull block 23. A grooved rod 25 is fixedly connected to one side of the rectangular block 21. A sliding hole 26 is opened in the inner wall of the grooved rod 25. The outer surface of one end of the limiting frame 27 is slidably connected to the inner wall of the grooved rod 25 and the inner wall of the sliding hole 26. One side of one end of the limiting frame 27 is fixedly connected to one end of the pull rope 24. A guide roller 29 is fixedly connected to the outer surface of one end of the grooved rod 25. The pull rope 24 is sleeved on the outer surface of the guide roller 29. A first spring 28 is sleeved on the outer surface of one end of the limiting frame 27. The two ends of the first spring 28 are fixedly connected to the limiting frame 27 and one side of the grooved rod 25, respectively. When using the walker, if you are not walking but just standing up, to prevent the roller 12 from slipping and causing the walker to wobble, you can manually hold the bracket 7 and pull the pull block 23 at the same time. This will cause the telescopic rod 22 to be stretched open. Then, rotate the pull rope 24 to move it to one end on the outer surface of the guide roller 29. The other end will pull the limiting frame 27 to slide downward in the inner wall of the groove rod 25 and the sliding hole 26, causing the first spring 28 to be stretched. This will cause one end of the limiting rod to abut against the ground, increasing the contact area and resistance between the support leg 11 and the ground, improving the stability of the walker, and preventing the roller 12 from slipping when walking. This makes it easier to use the walker. Similarly, when using the walker, you only need to release the pull block 23. Under the reset action of the first spring 28, the limiting frame 27 can be reset and retracted, without hindering the movement of the walker.

[0034] Figure 1-5 A bearing 210 is fixedly connected to the outer surface of one end of the guide roller 29, and the outer ring of the bearing 210 is fixedly connected to the outer surface of the grooved rod 25. By setting the bearing 210, the rotational wear between the guide roller 29 and the grooved rod 25 can be reduced, thereby improving the service life of the guide roller 29. Several anti-slip blocks 211 are fixedly connected to the bottom of the limiting frame 27, and the anti-slip blocks 211 are arranged at equal intervals. By setting the anti-slip blocks 211, the contact friction at the bottom of the limiting frame 27 can be increased, making it more secure and less prone to slippage after it abuts against the ground.

[0035] Figure 1-5Reinforcing rods 212 are fixedly connected to both sides of the rectangular block 21, with one side of each reinforcing rod 212 fixedly connected to the outer surface of the crossbeam 8. The effect of these components is that by setting the reinforcing rods 212, the connection area between the rectangular block 21 and the crossbeam 8 can be increased, making the connection more secure and less prone to breakage or damage. One end of the pull rope 24 has its outer surface penetrating and connected to the inner wall of one side of the rectangular block 21. By penetrating and connecting the pull rope 24 to the rectangular block 21, its pulling direction can be limited, facilitating the use of the pull rope 24.

[0036] Figure 1-5 A second spring 213 is sleeved and connected to the outer surface of the telescopic rod 22 shown. The two ends of the second spring 213 are fixedly connected to one side of the pull block 23 and the rectangular block 21, respectively. By setting the second spring 213, after pulling the pull block 23, it can be driven to return to its original position and move towards one side of the rectangular block 21, assisting the first spring 28 in its reset operation. A handle block 214 is fixedly connected to one side of the pull block 23. The longitudinal section of the handle block 214 is U-shaped. By setting the handle block 214, the contact area on one side of the pull block 23 can be increased, making it easier to manually grip and hook onto one side for convenient operation.

[0037] Working principle: When using the walking aid to assist people with mobility impairments to walk, the four support legs 11 are first inserted into the inner walls of the four second grooved threaded blocks 9 and the inner walls of both ends of the two crossbars 8. Then, the second threaded ring block 10 is slid on the support leg 11 to a certain position, and one end of its inner wall is screwed into the outer surface of the second grooved threaded block 9. Since one end of the first threaded ring block 4 and the second threaded ring block 10 are both set in a conical column shape, one end of the second grooved threaded block 9 can be squeezed and contracted to fix the support leg 11 in the inner wall of one end of the crossbar 8. Then, after the two brackets 7 are rotated to a certain angle on the inner wall of one end of the first adjusting frame 1 and the second adjusting frame 5 respectively, they are unfolded, causing the second locking block 13 to rotate on the first locking block 6 to a certain angle, and the inner walls of the two are aligned. At this time, the locking rod 1 is then... 4. Insert the first locking block 6 and the second locking block 13 into the inner wall to limit and fix them. Finally, according to the user's body shape, manually pull the second adjusting frame 5 to one end to a certain position in the inner wall of the first adjusting frame 1. Then slide the first threaded ring block 4 to one end to a certain position on the outer surface of the second adjusting frame 5. Then screw it into the outer surface of the first grooved threaded block 3 to press it. Fix the adjusted second adjusting frame 5 in the inner wall of the first adjusting frame 1. Change the distance between the two supports 7 to facilitate the use of people of different body shapes and improve the applicability of the walking aid. Similarly, when storing, the legs 11 can be removed and the support 7 can be rotated to a certain angle and folded on one side of the first adjusting frame 1 and the second adjusting frame 5. Fold it up for easy storage and convenient daily use.

[0038] When using the walker, if you are not walking but just standing up, to prevent the roller 12 from slipping and causing the walker to wobble, you can manually hold the bracket 7 and pull the pull block 23 at the same time. This will cause the telescopic rod 22 to be stretched open. Then, rotate the pull rope 24 to move it to one end on the outer surface of the guide roller 29. The other end will pull the limiting frame 27 to slide downward in the inner wall of the groove rod 25 and the sliding hole 26, causing the first spring 28 to be stretched. This will cause one end of the limiting rod to abut against the ground, increasing the contact area and resistance between the support leg 11 and the ground, improving the stability of the walker, and preventing the roller 12 from slipping when walking. This makes it easier to use the walker. Similarly, when using the walker, you only need to release the pull block 23. Under the reset action of the first spring 28, the limiting frame 27 can be reset and retracted, without hindering the movement of the walker.
