Description

Technical Field

[0001] This utility model relates to the field of walking aid technology, specifically to a walking aid with protective functions. Background Technology

[0002] A walking aid is a tool that helps the human body support its weight, maintain balance, and walk. It is also called a walking device or walking aid. Its main functions are to maintain body balance, reduce the weight-bearing load on the lower limbs, relieve pain, improve gait, and improve walking function. Among them, the walking aid used by children is a rehabilitation assistive device that can help children support their weight, maintain balance, and walk.

[0003] Current two-wheeled walking aids lack a braking and locking function. When a user leans on one, the entire walking aid may slide along with the user, causing the user's walking pace to be unable to keep up with the speed of the sliding walking aid, which may lead to the user falling.

[0004] The prior art includes Chinese Patent Publication No. CN215960992U, which addresses the aforementioned technical problems. The technical solution disclosed in this patent document is as follows: A walking aid includes a main frame and wheels. The main frame has four sets of legs, with stepped axles on the two legs furthest from the user. A telescopic sleeve is fitted over the stepped axles. The upper end of the telescopic sleeve is screwed to the outer wall of the legs, and the lower end of the telescopic sleeve has an arc-shaped brake plate. In its natural state, the telescopic sleeve always forces the brake plate to press against and lock the wheels. A control mechanism is provided on the main frame. The control end of the control mechanism is connected to the telescopic sleeve and is used to control the telescopic sleeve to retract, thereby forcing the brake plate to release the wheels. This walking aid has a simple structure and can automatically lock the wheels when not in use, preventing slippage. However, the walking aid is relatively lightweight, and if it encounters an obstacle or a child loses their grip, it is prone to tipping over, resulting in insufficient overall safety performance. Utility Model Content

[0005] The purpose of this invention is to provide a walking aid with protective functions to solve the problem that existing walking aids are relatively lightweight, but if they encounter obstacles or children lose their grip, they are prone to tipping over, resulting in insufficient overall safety performance.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A walking aid with protective functions includes a handrail; a pair of wheel frames are slidably connected to the bottom of the handrail via a pair of telescopic rods; a sleeve is fixedly installed on the top of each wheel frame on one side of each telescopic rod; a slide rod is slidably installed inside each sleeve; the top of each slide rod is fixedly connected to the bottom of the handrail; a screw is threaded onto one side of each sleeve; each screw extends into the interior of each sleeve and is rotatably mounted with a retaining plate via a bearing; a connecting frame is fixedly connected to the other side of each telescopic rod; an adjusting plate is slidably installed inside the connecting frame; a plug is inserted into the other side of the connecting frame, and the plug engages with the inner wall of the adjusting plate; a seat is fixedly installed on one side of the adjusting plate; a fixing frame is fixedly connected to the bottom of each wheel frame; a placement plate is provided inside each fixing frame; a weight-adding block is engaged on the top of each placement plate via a limiting block; and an adjusting component for adjusting the position of each placement plate is provided inside each fixing frame.

[0008] Existing walking aids are relatively lightweight, but they are prone to tipping over when encountering obstacles or when children lose their grip, resulting in insufficient overall safety. This application addresses this issue by installing a placement plate and securing the weight-adding block to the outer surface of the limiting block. This allows the weight-adding block to be connected to the placement plate, thus fixing it in place and increasing the weight of the wheel frame. This increases the overall weight of the walking aid, reducing the likelihood of tipping over and improving its overall safety performance. Furthermore, the weight-adding block can be removed at any time to reduce the weight of the wheel frame, facilitating the carrying and operation of the walking aid.

[0009] A further improvement of the present invention is that each adjusting component includes a lead screw, the other side surface of each lead screw is rotatably connected to the inside of each fixing frame through a bearing, and a slider is threadedly installed on the outer surface of each lead screw, and the top of each slider is fixedly connected to the bottom surface of each placement plate.

[0010] By adopting the above technical solution, an adjustment component is installed. By rotating the lead screw, the slider can be moved, which in turn moves the placement plate synchronously. The position of the weight-adding block is adjusted, thereby adjusting the center of gravity of the wheel frame to adapt to the different postures of different children using the walker. This further reduces the possibility of the walker tipping over and improves the overall protective performance.

[0011] A further improvement of this utility model is that: one side of each lead screw extends into the interior of each fixed frame, and a handwheel is fixedly installed on one side of each lead screw.

[0012] By adopting the above technical solution, the contact area between the operator's hand and the lead screw can be increased by installing a handwheel, so as to facilitate the rotation operation of the lead screw.

[0013] A further improvement of the present invention is that: each placement plate at the outer end of each weight-adding block is slidably mounted with a baffle by several springs, the top of each baffle extends out of the interior of each placement plate and fits against the outer surface of each weight-adding block, and a connecting plate is fixedly mounted at the outer end of each baffle.

[0014] By adopting the above technical solution, the spring itself can exert a pushing force on the baffle to the top, so that the baffle blocks the outer end of the weight block, thereby reducing the possibility of the weight block detaching from the top of the placement plate and improving the stability of the weight block installation.

[0015] A further improvement of this utility model is that the outer end of each connecting plate extends out of the interior of each placement plate, and a movable plate is fixedly installed on the outer surface of each connecting plate.

[0016] By adopting the above technical solution, the contact area between the operator's hand and the connecting plate can be increased by installing a movable plate, so as to facilitate the movement of the connecting plate and thus adjust the position of the baffle.

[0017] A further improvement of this utility model is that: each baffle at the top of each connecting plate has an inclined surface that slopes inward toward the top.

[0018] In this technical solution, by creating an inclined surface on the baffle, the weight block can press against the inclined surface of the baffle as it moves from the outer end of the placement plate to the top of the placement plate, causing the baffle to move to the bottom. This facilitates moving the weight block to the top of the placement plate without requiring the operator to manually push the baffle to the bottom, reducing the number of operation steps and improving work efficiency.

[0019] A further improvement of this utility model is that the inner end of the weight-adding block on the outer surface of each limiting block has an opening larger than the outer surface of the limiting block.

[0020] In the above technical solution, an opening larger than the area of ​​the limiting block is made on the surface of the weight-adding block to facilitate alignment of the weight-adding block with the limiting block and to snap the weight-adding block onto the outer surface of the limiting block.

[0021] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0022] 1. This utility model provides a walking aid with protective function. By using a limiting block to connect the weight-adding block to the placement plate, the weight-adding block can be installed and fixed, thereby increasing the weight of the wheel frame, which increases the overall weight of the walking aid, reduces the possibility of the walking aid tipping over, improves the overall protective performance, and the weight-adding block can be removed at any time to facilitate the operator's carrying and operation of the walking aid.

[0023] 2. This utility model provides a walking aid with protective function. By adjusting the cooperation between the components, the slider can be moved by rotating the lead screw, which can drive the placement plate to move synchronously, thereby adjusting the position of the weight block and thus adjusting the center of gravity of the wheel frame to adapt to the different postures of different children when using the walking aid. This further reduces the possibility of the walking aid tipping over and improves the overall protective performance.

[0024] 3. This utility model provides a walking aid with protective function. It uses a spring to press the baffle at the top, so that it blocks the outer end of the weight block. This reduces the possibility of the weight block detaching from the top of the placement plate, thereby improving the stability of the weight block installation and further improving the overall protective performance.

[0033] The present invention will be further described in detail below with reference to embodiments:

[0034] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a walking aid with protective functions, including a handrail 2; a pair of wheel frames 1 are slidably connected to the bottom of the handrail 2 via a pair of telescopic rods 10, and a sleeve 3 is fixedly installed on the top of each wheel frame 1 on one side of each telescopic rod 10. A sliding rod 4 is slidably installed inside each sleeve 3, and the top of each sliding rod 4 is fixedly connected to the bottom of the handrail 2. A screw 9 is threadedly installed on one side of each sleeve 3, and each screw 9 extends into the interior of each sleeve 3 and is rotatably mounted with a clamping plate 16 via a bearing. The other side of each telescopic rod 10... One side is fixedly connected by a connecting frame 18. An adjusting plate 19 is slidably installed inside the connecting frame 18. A plug 20 is inserted into the other side of the connecting frame 18. The plug 20 engages with the inner wall of the adjusting plate 19. A seat 17 is fixedly installed on one side of the adjusting plate 19. A fixing frame 11 is fixedly connected to the bottom of each wheel frame 1. A placement plate 6 is provided inside each fixing frame 11. A weight-adding block 7 is engaged at the top of each placement plate 6 by a limiting block 12. An adjusting component 5 for adjusting the position of each placement plate 6 is provided inside each fixing frame 11.

[0035] In this embodiment, the existing walking aid is relatively lightweight. If it encounters an obstacle or if a child loses their grip, it is easy for the walking aid to tip over, resulting in insufficient overall safety performance. In this application, by installing the placement plate 6, the weight-adding block 7 is clipped onto the outer surface of the limiting block 12, which connects the weight-adding block 7 to the placement plate 6, thereby fixing the weight-adding block 7 and increasing the weight of the wheel frame 1. This increases the overall weight of the walking aid, thereby reducing the possibility of the walking aid tipping over and improving the overall protective performance. Furthermore, the weight-adding block 7 can be removed at any time to reduce the weight of the wheel frame 1, making it easier to carry the walking aid.

[0036] Example 2: As Figure 1 and Figure 2As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, each adjusting component 5 includes a lead screw 501, the other side surface of each lead screw 501 is rotatably connected to the interior of each fixing frame 11 via bearings, the outer surface of each lead screw 501 is threaded with a slider 502, the top of each slider 502 is fixedly connected to the bottom surface of each placement plate 6, one side of each lead screw 501 extends out of the interior of each fixing frame 11, and a handwheel 503 is fixedly installed on one side of each lead screw 501.

[0037] In this embodiment, by installing the adjustment component 5, rotating the lead screw 501 can drive the slider 502 to slide, thereby driving the placement plate 6 to move synchronously and adjusting the position of the weight block 7, thus adjusting the center of gravity of the wheel frame 1 to adapt to the different postures of different children using the walker, thereby further reducing the possibility of the walker tipping over and improving the overall protective performance; by installing the handwheel 503, the contact area between the operator's hand and the lead screw 501 can be increased to facilitate the rotation operation of the lead screw 501.

[0038] Example 3: Figure 1 , Figure 3 and Figure 4 As shown, based on Embodiment 2, this utility model provides a technical solution: Preferably, each placement plate 6 at the outer end of each weight-adding block 7 is slidably mounted with a baffle 8 by a plurality of springs 13. The top of each baffle 8 extends out of the interior of each placement plate 6 and is in contact with the outer surface of each weight-adding block 7. A connecting plate 14 is fixedly mounted on the outer end of each baffle 8. The outer end of each connecting plate 14 extends out of the interior of each placement plate 6, and a movable plate 15 is fixedly mounted on the outer surface of each connecting plate 14. The outer surface of each baffle 8 at the top of each connecting plate 14 is provided with an inclined surface that slopes towards the inner end of the top. The inner end of the weight-adding block 7 on the outer surface of each limiting block 12 is provided with an opening larger than the outer surface of the limiting block 12.

[0039] In this embodiment, the spring 13 exerts its own elastic force on the baffle 8, pushing it upwards and preventing it from detaching from the top of the weight block 7. This reduces the likelihood of the weight block 7 falling off the top of the placement plate 6 and improves the stability of the weight block 7 installation. The movable plate 15 increases the contact area between the operator's hand and the connecting plate 14, facilitating the movement of the connecting plate 14 and adjusting the position of the baffle 8. By creating a slope on the surface of the baffle 8, the weight block 7 can press against the slope of the baffle 8 as it moves from the outer end of the placement plate 6 to the top, causing the baffle 8 to move downwards and move the weight block 7 to the top of the placement plate 6. This eliminates the need for the operator to manually push the baffle 8 downwards, reducing the number of steps and improving work efficiency. By creating an opening on the surface of the weight block 7 larger than the area of ​​the limiting block 12, the weight block 7 can be aligned with the limiting block 12 and snapped onto the outer surface of the limiting block 12.

[0040] The working principle of this protective walking aid is explained in detail below.

[0041] like Figures 1-6 As shown, before using the walker, depending on the child's height, the operator can rotate the screw 9 to one side, simultaneously moving the locking plate 16 to separate it from the surface of the slide rod 4. The operator can then slide the slide rod 4 inside the sleeve 3 to adjust the height of the armrest 2. After adjustment, the operator can rotate the screw 9 in the opposite direction, causing the locking plate 16 to again adhere to and press against the surface of the slide rod 4. Then, the bolt 20 is removed, and the adjusting plate 19 is slid inside the connecting frame 18 to adjust the height of the seat 17. The bolt 20 is then inserted into the connecting frame 18 and the adjusting plate 19 to limit the position of the seat 17. Finally, from the outside... The weight block 7 is moved to the top of the placement plate 6, and then the spring 13 pushes the baffle 8 upward, so that the baffle 8 fits against the weight block 7 and limits the weight block 7, thereby increasing the weight of the wheel frame 1. In addition, depending on the different postures of different children using the walker, the operator manually turns the handwheel 503, which drives the lead screw 501 to rotate, thereby moving the slider 502 and the placement plate 6 to adjust the position of the weight block 7, thereby adjusting the center of gravity of the wheel frame 1 to adapt to the different postures of different children using the walker, thereby further reducing the possibility of the walker tipping over and improving the overall protective performance.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
