Description

Technical Field

[0001] The utility model relates to the technical field of walking aids, in particular to a portable multifunctional walking aid. Background Art

[0002] A walker is a device that helps the human body support weight, maintain balance and walk. The technical background of this device is mainly reflected in its design and function. The walker has the function of assisting walking and completing daily actions. The walker can detect the trend of leg steps, identify what action the user is going to do and complete the action. If the user has a tendency to lean to one side too much and there is a possibility of falling, the walker will also step a certain distance in that direction to maintain balance.

[0003] If a walker has wheels when used, this can reduce the force people use on it during use, but without a brake function, it will be difficult to control the balance of the walker during walking. When on a slope, it is difficult to control the sliding speed of the walker, which will increase the risk of falling when the user is using it, and reduce safety: when a walker without a brake function encounters an emergency, the user cannot slow down or stop in time and effectively, thereby increasing the risk of injury.

[0004] In view of the above situation, in order to overcome the above technical problems, the utility model designs a portable multifunctional walking aid device to solve the above technical problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is that when using a walker, the lack of a brake function makes it difficult to control the balance of the walker during walking, and it is difficult to control the sliding speed of the walker on a slope, which increases the risk of the user falling when using the walker.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The utility model provides a portable multifunctional walking aid, comprising a bracket, a railing, a crossbar and a handle, wherein the railing is installed above the bracket, the crossbar is installed between the brackets, and the handle is installed on the bracket. The handle drives a transmission rope to move horizontally through the rotation of the handle, and the horizontally moving transmission rope drives a rotating disk in the railing to rotate, and the rotating rotating disk squeezes the mainspring to produce deformation, and at the same time, the transmission rope drives the sealing cylinder and the sliding disk in the bracket to move vertically in the opposite direction when moving, thereby driving the airbag to expand outward.

[0008] The grip includes a grip rod, a sliding groove, a support rod, a handle and a transmission rope. Grip rods are installed at both ends of the railing. The cross-sectional shape of the grip rod is Z-shaped. A sliding groove is provided at the upper end of the grip rod. A support rod is installed inside the grip rod. A handle is installed on the support rod. A fixing hole is provided on the handle. The fixing hole is below the support rod, and a transmission rope is installed on the fixing hole.

[0009] Preferably, the Z-shaped grip bar is designed to provide better support for the person sitting up, and avoid the situation where the person has no support point when standing up due to the bracket being too high, which causes the person to use a lot of strength to support himself or herself to stand up, thus affecting the person's walking. When the person reaches the upper end of the grip bar, since the support rod is above the fixing hole, the person can pull the transmission rope when pressing the handle, thereby pulling the structure inside the bracket.

[0010] The bracket includes a support frame, a fixed cylinder, a rotating rod, a sealing cylinder and a sliding disk. The support frame is installed at the lower end of the cross bar, two fixed cylinders are installed on the side of the support frame, a rotating rod is installed inside the support frame, a sealing cylinder is installed below the rotating rod, two grooves are provided on the side of the sealing cylinder, the cross-sectional shape of the grooves is rectangular, and a sliding hole is provided on the upper surface of the sealing cylinder, a sliding disk is installed inside the sealing cylinder, and a transmission rope is connected to the top of the sliding disk.

[0011] Preferably, a fixing cylinder is installed on the side of the support frame, so that the walker can be more stable during movement, and the rotating rod of the support frame can adjust the height of the sealing cylinder, so that the height of the sealing barrel to the ground can be adjusted by pulling the transmission rope by the handle, so that the sealing cylinder is easier to fit with the ground, which helps to make the walking of the walker more stable. At the same time, a groove is provided on the side of the sealing cylinder, so that the sealing cylinder can discharge gas into the fixing cylinder at any time when moving, so as to inflate the airbag, thereby fixing the roller, and preventing the roller from rolling on an inclined surface, thereby trying to endanger people.

[0012] An airbag is installed inside the fixed cylinder, a support plate is installed at the front end of the airbag, the cross-section of the support plate is an arc shape, a roller is installed on the periphery of the fixed cylinder, and a roller is installed on the side of the roller.

[0013] Preferably, the sealing cylinder and the sliding disk move relative to each other, so that the gas inside the sealing cylinder enters the airbag through the groove, so that the airbag expands, thereby pushing the support plate to move to both sides. The support plate adopts an arc shape, mainly to prevent the airbag from being easily damaged when expanding and squeezing the support plate. In order to avoid damage to the airbag, the support plate adopts an arc shape to increase the contact area between them, so that the airbag can better push the support plate, so that it fixes the roller and prevents the roller from rotating.

[0014] An extrusion rod is installed at the center position of the support plate, and the cross-sectional shape of the extrusion rod is a cross. A restoring spring is clamped on the extrusion rod, and the other end of the restoring spring is clamped on the fixed plate. The cross-sectional shape of the fixed plate is an arch, and a limiting disk is installed on the other end of the extrusion rod.

[0015] Preferably, the extrusion rod is in a cross shape to provide more stable extension and contraction of the restoring spring, avoiding the displacement of the restoring spring during the extension and contraction process, which may cause the restoring spring to deform and further damage the internal structure; the cross-sectional shape of the fixed plate is an arch, and the inside of the arch is an arc shape, which can not only fix the length of the restoring spring, but also limit the position of the restoring spring, thereby extending the practical time of the restoring spring, protecting the spring while also protecting the internal structure.

[0016] The cross-section of the limiting plate is in the shape of a minor arc, the outer diameter of the limiting plate is equal to the inner diameter of the roller, and the direction of the limiting plate is perpendicular to the direction of the supporting plate.

[0017] Preferably, the limit plate adopts a minor arc shape, which can make the limit plate expand outward while contacting the inside of the roller with a larger area, and the outer diameter of the limit plate is equal to the inner diameter of the roller, which helps to increase the contact area between the limit plate and the roller, thereby increasing the friction between them and enabling the limit plate to better fix the roller and prevent it from rotating.

[0018] An adjusting rod is installed on the rotating rod, and both ends of the adjusting rod are retractable. One section of the adjusting rod is installed on the transmission rope, and the other end of the adjusting rod is installed with a transmission rod, and the other end of the transmission rod is installed on the sealing cylinder.

[0019] Preferably, the adjusting rod is telescopic, which helps the transmission rope to be stretched so that the adjusting rod squeezes the sealing cylinder, causing the sealing cylinder to move, thereby adjusting the distance between the sealing cylinder and the ground, making it easier for the sealing cylinder to fit closely to the ground, thereby increasing the fixation of the walker to the ground. In any case, the walker will tilt due to the pushing effect on a slope, which may cause a person to fall while using the walker.

[0020] A fixed plate is installed at both ends of the railing, and the cross-sectional shape of the fixed plate is convex. The upper end of the fixed plate is installed at the two ends of the railing, and the diameter value of the lower end of the convex fixed plate is equal to the inner diameter value of the railing. Two supporting blocks are installed on the fixed plate, and a fixing groove is opened on the fixed plate between the supporting blocks. A spring is installed on the fixing groove, and a rotating plate is installed at the other end of the spring, and the rotating plate is installed between the supporting blocks.

[0021] Preferably, the fixing plate is convex in shape, which can fix the bottom end to the railing, reducing the overall weight of the walker, and the design of the convex fixing plate can better cooperate with the railing, increase the stability of the fixation, and effectively prevent the shaking and loosening of the railing. The railing support block is installed to limit the rotating plate to prevent the rotating plate from shifting, thereby causing the transmission rope to be unable to drive the rotating plate to rotate, and the diameter of the fixing plate is the same as the inner diameter of the railing, which helps to fix the fixing plate and prevent the fixing plate from shifting and shaking during use.

[0022] The outer array of the rotating disk is provided with rotating grooves, the interior of the rotating disk is provided with a limiting groove, and the other end of the mainspring is installed inside the limiting groove.

[0023] Preferably, the rotating grooves of the outer array of the rotating disk and the internal limiting grooves enable the fixing structure of the railing to more accurately adjust the fixing position and angle of the railing to adapt to different installation environments and requirements. The existence of the limiting grooves can limit the movement range of the spring to ensure that the railing fixing structure is adjusted within a fixed range. The design of the rotating disk and the limiting grooves takes into account the wear and tear during long-term use, and is made of wear-resistant materials with strong durability. This ensures that the fixing structure can still maintain good performance and stability during long-term use.

[0024] The beneficial effects of the utility model are as follows:

[0025] 1. By designing a support frame, a fixed cylinder is installed on the side of the support frame, which can make the walker more stable during movement, and the rotating rod of the support frame can adjust the height of the sealing cylinder, so that the height of the sealing barrel to the ground can be adjusted by pulling the transmission rope through the handle, so that the sealing cylinder is easier to fit with the ground, which helps to make the walking of the walker more stable.

[0026] 2. By designing a limit plate, the limit plate adopts an inferior arc shape, which can make the limit plate expand outward while contacting the inside of the roller with a larger area, and the outer diameter of the limit plate is equal to the inner diameter of the roller, which helps to increase the contact area between the limit plate and the roller, thereby increasing the friction between them and making the limit plate better fix the roller to prevent it from rotating.

[0027] 3. By designing a handrail, the handrail support block limits the rotating disk to prevent the rotating disk from shifting, which makes the transmission rope unable to drive the rotating disk to rotate, and the diameter of the fixed disk is the same as the inner diameter of the handrail, which helps to fix the fixed disk and prevent the fixed disk from shifting and shaking during use.

DETAILED DESCRIPTION

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] like Figure 1As shown, the utility model provides a portable multifunctional walking aid, including a bracket 1, a railing 2, a crossbar 3 and a handle 4. The railing 2 is installed above the bracket 1, the crossbar 3 is installed between the brackets 1, and the handle 4 is installed on the bracket 1. The handle 4 drives the transmission rope 45 to move horizontally through the rotation of the handle 44. The horizontally moving transmission rope 45 drives the rotating disk 24 in the railing 2 to rotate. The rotating rotating disk 24 squeezes the clockwork 23 to deform. At the same time, the transmission rope 45 drives the sealing cylinder 14 and the sliding disk 15 in the bracket 1 to move vertically in the opposite direction when moving, thereby driving the airbag 121 to expand outward.

[0038] like Figure 2 As shown, the grip 4 includes a grip rod 41, a sliding groove 42, a support rod 43, a handle 44 and a transmission rope 45. The grip rods 41 are installed at both ends of the railing 2. The cross-sectional shape of the grip rod 41 is Z-shaped. The upper end of the grip rod 41 is provided with a sliding groove 42. The inside of the grip rod 41 is installed with a support rod 43. The support rod 43 is provided with a handle 44. The handle 44 is provided with a fixing hole 441. The fixing hole 441 is below the support rod 43. The transmission rope 45 is installed on the fixing hole 441.

[0039] The Z-shaped grip 41 is designed to provide better support for the person who is sitting up, so as to avoid the situation that the person has no support point when standing up due to the bracket 1 being too high, and thus needs to use force to support himself to stand up, which affects his walking. When the person reaches the upper end of the grip 41, since the support rod 43 is below the fixing hole 441, when the handle 44 is pressed, the transmission rope 45 can be pulled, thereby pulling the structure inside the bracket 1.

[0040] like Figure 3 As shown, the bracket 1 includes a support frame 11, a fixed cylinder 12, a rotating rod 13, a sealing cylinder 14 and a sliding disk 15. The support frame 11 is installed at the lower end of the cross bar 3, and two fixed cylinders 12 are installed on the side of the support frame 11. The rotating rod 13 is installed inside the support frame 11, and a sealing cylinder 14 is installed below the rotating rod 13. Two grooves 141 are provided on the side of the sealing cylinder 14, and the cross-sectional shape of the grooves 141 is rectangular. A sliding hole 142 is provided on the upper surface of the sealing cylinder 14, and a sliding disk 15 is installed inside the sealing cylinder 14. A transmission rope 45 is connected to the top of the sliding disk 15.

[0041] A fixed cylinder 12 is installed on the side of the support frame 11, which can make the walker more stable during movement. The rotating rod 13 of the support frame 11 can adjust the height of the fixed cylinder 12, and the transmission rope 45 is pulled by the handle 44 to adjust the height of the sealing barrel to the ground. This makes it easier for the sealing cylinder 14 to fit the ground, which helps the walker to walk stably. In addition, a groove 141 is provided on the side of the sealing cylinder 14, which allows the sealing cylinder 14 to discharge gas into the fixed cylinder 12 at any time during movement, so as to inflate the airbag 121, thereby fixing the roller 124 to prevent the roller 124 from rolling on an inclined surface and posing a threat to human safety.

[0042] like Figure 3 and 6 As shown, an airbag 121 is installed inside the fixed cylinder 12, a support plate 122 is installed at the front end of the airbag 121, and the cross-sectional shape of the support plate 122 is an arc shape. A roller 123 is installed on the periphery of the fixed cylinder 12, and a roller 124 is installed on the side of the roller 123.

[0043] Through the mutual movement of the sealing cylinder 14 and the sliding plate 15, the gas can be introduced into the airbag 121, so that the airbag 121 expands and pushes the support plate 122 to move to both sides. The support plate 122 adopts an arc-shaped design to increase the contact area between it and the airbag 121 to prevent the airbag 121 from being damaged when expanding and squeezing. This design helps to ensure that the roller 124 is fixed to prevent it from rotating during use.

[0044] like Figure 5 and 6 As shown, an extrusion rod 1221 is installed at the center position of the support plate 122, and the cross-sectional shape of the extrusion rod 1221 is a cross shape. A return spring 1222 is clamped on the extrusion rod 1221, and the other end of the return spring 1222 is clamped on the fixed plate 1223, and the cross-sectional shape of the fixed plate 1223 is an arch shape. A limiting disk 1224 is installed on the other end of the extrusion rod 1221.

[0045] The extrusion rod 1221 adopts a cross-shaped design, which can provide more stable support for the expansion and contraction of the restoring spring 1222, avoiding deviation during the expansion and contraction process, causing the spring to deform or even damage the internal structure. The cross-sectional shape of the fixing plate 1223 is an arch, and the interior is an arc shape, which can not only fix the length of the restoring spring 1222, but also limit the position of the restoring spring 1222, thereby extending its service life and protecting the internal structure. This design helps to ensure the stability and reliability of the restoring spring 1222.

[0046] like Figure 6As shown, the cross-sectional shape of the limiting plate 1224 is a minor arc shape, the outer diameter of the limiting plate 1224 is equal to the inner diameter of the roller 123 , and the direction of the limiting plate 1224 is perpendicular to the direction of the support plate 122 .

[0047] The limiting plate 1224 is designed in a bad arc shape. When it expands outward, it can contact the inside of the roller 123 more comprehensively, thereby increasing the contact area between the limiting plate 1224 and the roller 123. In addition, the outer diameter of the limiting plate 1224 is equal to the inner diameter of the roller 123, which further expands the contact area between them and increases the friction force, so that the limiting plate 1224 can more firmly fix the roller 123 to prevent it from rotating. This design improves the stability and reliability between the limiting plate 1224 and the roller 123.

[0048] like Figure 3 As shown, an adjusting rod 131 is installed on the rotating rod 13, and both ends of the adjusting rod 131 are retractable. One section of the adjusting rod 131 is installed on the transmission rope 45, and a transmission rod 132 is installed on the other end of the adjusting rod 131, and the other end of the transmission rod 132 is installed on the sealing cylinder 14.

[0049] The adjusting rod 131 is telescopic, which helps the transmission rope 45 to be stretched, so that the adjusting rod 131 squeezes the sealing cylinder 14, causing the sealing cylinder 14 to move, thereby adjusting the distance between the sealing cylinder 14 and the ground, making it easier for the sealing cylinder 14 to fit closely to the ground, thereby increasing the fixation of the walker to the ground. In any case, the walker tilts due to the pushing effect on a slope, which may cause a person to fall while using the walker.

[0050] like Figure 4 As shown, fixed plates 21 are installed at both ends of the railing 2, and the cross-sectional shape of the fixed plate 21 is convex. The upper ends of the fixed plates 21 are installed at both ends of the railing 2, and the diameter value of the lower end of the convex fixed plate 21 is equal to the inner diameter value of the railing 2. Two supporting blocks 22 are installed on the fixed plate 21, and a fixing groove 211 is opened on the fixed plate 21 between the supporting blocks 22. A spring 23 is installed on the fixing groove 211, and a rotating plate 24 is installed at the other end of the spring 23. The rotating plate 24 is installed between the supporting blocks 22.

[0051] The fixing plate 21 is convex in shape, so that the bottom end can be fixed to the handrail 2, reducing the overall weight of the walker, and the design of the convex fixing plate 21 can better cooperate with the handrail 2, increasing the stability of the fixation, and effectively preventing the handrail 2 from shaking and loosening. The support block 22 of the handrail 2 is installed to limit the rotating plate 24 to prevent the rotating plate 24 from shifting, and the transmission rope 45 cannot drive the rotating plate 24 to rotate, and the diameter of the fixing plate 21 is the same as the inner diameter of the handrail 2, which helps to fix the fixing plate 21 and prevent the fixing plate 21 from shifting and shaking during use.

[0052] like Figure 4 As shown, the outer array of the rotating disk 24 is provided with rotating grooves 241 , the interior of the rotating disk 24 is provided with a limiting groove 242 , and the other end of the mainspring 23 is installed inside the limiting groove 242 .

[0053] The rotating grooves 241 of the outer array of the rotating disk 24 and the internal limiting grooves 242 enable the fixing structure of the railing 2 to more accurately adjust the fixing position and angle of the railing 2 to adapt to different installation environments and requirements. The existence of the limiting grooves 242 can limit the movement range of the spring 23 to ensure that the fixing structure of the railing 2 is adjusted within a fixed range. The design of the rotating disk 24 and the limiting grooves 242 takes into account the wear and tear during long-term use. They are made of wear-resistant materials and have strong durability. This ensures that the fixing structure can still maintain good performance and stability during long-term use.

[0054] During the working process of the utility model, when a person is using the walker, he or she can first apply force to the handle 44 with his or her hand during the movement, so that the handle 44 is vertically displaced, and the vertically displaced handle 44 pulls the transmission rope 45, and the transmission rope 45 drives the rotating disk 24 to rotate during the movement. Since the limiting groove 242 fixes the mainspring 23, the rotating disk 24 drives the mainspring 23 to deform during the rotation, so that the transmission rope 45 pulls the sliding disk 15, and the sliding disk 15 allows the gas inside the sealing tube 14 to enter the airbag 121 from the groove 141, and the support plate 122 is squeezed through the expansion of the airbag 121, and the support plate 122 moves toward the periphery, and the fixing plate 1223 is driven to move toward the inside of the drum 123 by the outward movement of the squeezing rod 1221, and then the roller 124 is fixed, so that the roller 124 does not rotate, thereby protecting the stability of the person when pushing.

[0055] The technical features disclosed above are not limited to the combination with other features disclosed. Those skilled in the art may also make other combinations between the technical features according to the purpose of disclosure to achieve the purpose of this disclosure.
