[0025] like Figure 5 , 6As shown, the limit control device 200 is movably installed between the two front support rods 110. The limit control device 200 is composed of a limit sleeve 210, a control sleeve 220, a push rod 230, a limit block 240 and a spring 250. The limit sleeve 210 is a T-shaped sleeve formed by vertically connecting a vertical end column and a horizontal end column. There are two limit sleeves 210. The two limit sleeves 210 are movably mounted between the magnet 1 112 and the magnet 2 113 on the two front support rods 110 in a manner of connecting the bottom ends of the horizontal ends. One of the limiting sleeves 210 is provided with a through retreat groove 211 on the outer circumferential surface of the joint, and the retreat groove 211 is an F-shaped groove composed of a longitudinal groove and two circumferential grooves, and penetrates the horizontal end bottom circumferential surface of the limiting sleeve 210.

[0026] The control sleeve 220 is movably installed at the joint of the two limiting sleeve heads 210. The inner diameter of the control sleeve 220 is the same as the outer diameter of the horizontal end of the limiting sleeve head 210. A bell mouth 221 is respectively provided at both ends of the control sleeve 220. The bell mouth 221 can make the control sleeve 220 move more smoothly at the joint of the two limiting sleeve heads 210. A limiting column 222 is also provided at the bottom end of each of the two bell mouths 221. The diameter of the limiting column 222 is the same as the size of the recessed notch 211 or the locked notch 212. When the control sleeve 220 moves between the two limiting sleeve heads 210, the two limiting columns 222 on the control sleeve 220 22 can move in the slot of the retreat slot 211 or the locking slot 212. When the limiting column 222 on the control sleeve 220 close to one end of the locking slot 212 moves to the circumferential slot on the locking slot 212, the limiting column 222 at the other end of the control sleeve 220 is located at the first circumferential slot on the retreat slot 211 close to the locking slot 212. Then the entire control sleeve 220 is rotated in the direction of the circumferential slot, so that the two limiting columns 222 on the control sleeve 220 are respectively rotated into the circumferential slot of the locking slot 212 and the first circumferential slot of the retreat slot 211. At this time, the two limiting columns 222 on the control sleeve 220 are 22 By clamping the retreat notches 211 on the two limit sleeves 210 and the circumferential notches of the locking notches 212, the two limit sleeves 210 are fixed at the horizontal end joints. At this time, the limit control device 200 is in a locked state. When the two limit posts 222 on the control sleeve 220 are respectively rotated into the two circumferential notches on the retreat notches 211, the flared mouth 221 at one end of the control sleeve 220 facing the locking notches 212 will be flush with the docking port of the limit sleeve 210 with the locking notches 212. At this time, the two limit sleeves 210 will be released and can move freely, and the limit control device 200 is in an unlocked state. State, a magnet three 213 is respectively provided at both ends of the vertical end of the limiting sleeve 210. When the limiting sleeve 210 moves upward, the magnet three 213 at the upper end of the limiting sleeve 210 will be magnetically attracted to the magnet two 113 on the front support rod 110. When the limiting sleeve 210 moves downward, the magnet three 213 at the lower end of the limiting sleeve 210 will be magnetically attracted to the magnet one 112 on the front support rod 110. A cylindrical pin 214 is also provided at the upper end of the magnet three 213 at the bottom of each limiting sleeve 210. The cylindrical pin 214 passes through the vertical end of the limiting sleeve 210 and passes through the limiting slot one 114 at the upper end of the front support rod 110.

[0027] The push rod 230 is movably installed inside the two front support rods 110 and the front support leg 120. The top end of the push rod 230 can be against the cylindrical pin 214 when the limiting sleeve 210 moves to the bottom. The bottom end of the push rod 230 is provided with a limiting block 240. The limiting block 240 is limitedly installed at the upper end of the limiting slot 121. A trapezoidal clamping head 241 is provided below the limiting block 240, and the trapezoidal clamping head 241 can be clamped into the tooth groove 171 on the middle connecting rod 170 in the support frame 100 as a whole. A spring 250 is installed between the upper end surface of the limiting block 240 and the bottom end surface of the front support rod 110. The trapezoidal clamping head 241 on the limiting block 240 will be tightly pressed against the middle connecting rod 170 under the elastic force of the spring 250.

[0028] like Figure 5 , 7 As shown, the movable pull rod 300 is movably and symmetrically installed between the two front support rods 110, and the movable pull rod 300 is composed of a connecting sleeve 310, a spring 2 320 and a middle pull rod 330, wherein there are two connecting sleeves 310, which are movably and non-rotatably installed between the limit ring 111 and the magnet 1 12 on each front support rod 110 (there is a tooth groove inside the connecting sleeve 310, which is not shown in the figure), and the connecting sleeve 310 as a whole is also formed by a T-shaped sleeve formed by vertically connecting a vertical end column and a horizontal end column, and two symmetrical semi-ring notches 311 are also provided on the outer periphery of the horizontal end of the connecting sleeve 310, and a spring 2 320 is also installed between the vertical end of each connecting sleeve 310 and the magnet 1 112 on the front support rod 110, and the spring 2 320 presses the connecting sleeve 310 against the limit ring 111 on the front support rod 110 by elastic force;

[0029] like Figure 8 , 9 As shown, the middle pull rod 330 is rotatably installed between the two connecting sleeves 310, and both ends of the middle pull rod 330 are provided with a bayonet 331. When both ends of the middle pull rod 330 are installed in the horizontal end pipe openings on the two connecting sleeves 310, both ends of the bayonet 331 at both ends of the middle pull rod 330 will be limited in the two semi-annular grooves 311, and two semi-annular springs 340 are also fixedly installed in the semi-annular grooves 311. The middle part of each semi-annular spring 340 is fixed at the junction with the two semi-annular grooves 311, and the two ends are respectively fixed to the two ends of the bayonet 331. When the middle pull rod 330 drives the bayonet 331 to rotate, the bayonet 331 will compress or stretch the semi-annular spring 340.

[0030] Working principle of the present invention:

[0031] When walking on a flat road, the rear support rod 130 and the rear support leg 140 on the support frame 100 are in a state of bending at a small angle, the upper connecting rod 150 is in a horizontal state, and the magnet three 213 on the limit control device 200 is attracted to the magnet one 112, so that the limit sleeve 210 is vertically locked, and the two support frames 100 will not be able to easily move up and down relative to each other. At this time, the cylindrical pin 214 presses on the top rod 230, so that the top rod 230 cannot move upward, and then the trapezoidal clamping head 241 on the limit block 240 is engaged with the tooth groove 171 on the middle connecting rod 170, so that the middle connecting rod 170 cannot move, so that the relative shape of the rear support rod 130 and the rear support leg 140 on the support frame 100 will not change, and at the same time the control The two limit posts 222 on the sleeve 220 are stuck in the circumferential grooves of the retreat grooves 211 and the locking grooves 212 on the two limit sleeve heads 210, so that the two limit sleeve heads 210 are fixed at the horizontal end joints, so that the limit control device 200 is locked circumferentially and longitudinally, so that the two support frames 100 cannot rotate relative to each other. When walking on a downhill road, the limit control device 200 is lifted upward until the magnet three 213 at the upper end of the limit sleeve head 210 is attracted and fixed with the magnet two 113 on the front support rod 110. At this time, the cylindrical pin 214 on the limit sleeve head 210 is separated from the top rod 230, and the top rod 230 has space to move upward. At this time, the upper connecting rod 150 is pressed backward with force, and then the middle connecting rod 170 is forced to move in the limit groove. The upper connecting rod 150 is moved forward in the opening 121, and at the same time, the rear support rod 130 and the rear support leg 140 are bent inward at the hinge, thereby driving the upper connecting rod 150 to rotate downward relative to the top of the front support rod 110. Since the limit block 240 is subjected to the elastic force of the spring 1 250 pressing downward, the trapezoidal clamping head 241 below the limit block 240 will be stuck in the tooth groove 171 on the middle connecting rod 170. Therefore, when the middle connecting rod 170 moves relative to the limit block 240, the tooth groove 171 on the middle connecting rod 170 will push the trapezoidal clamping head 241 to compress the spring 1 250 and move upward. After the middle connecting rod 170 moves through a tooth groove 171, the trapezoidal clamping head 241 will again block the next tooth groove 171 under the action of the spring 1 250, so that the middle connecting rod 170 is relatively When the limit block 240 moves, the middle link 170 does not move continuously, but moves one by one with the tooth grooves 171, so as to prevent the middle link 170 from moving too far when being thrust, and facilitate the control of the inclination angle of the upper link 150. When the inclination angle of the upper link 150 is sufficient, the limit control device 200 is pushed downward until the magnet three 213 at the lower end of the limit sleeve 210 is attracted and fixed with the magnet one 112 on the front support rod 110. At this time, the cylindrical pin 214 on the limit sleeve 210 will resist the push rod 230, so that the push rod 230 cannot move upward, and then the lower link 160 cannot move, thus completing the shape fixation of the support frame 100. At this time, when the walker is walking on the slope, the upper link 150 is always in a horizontal state.To ensure the stability of the user when walking on a slope, the slope walking state is as follows: Fig.10 As shown, when encountering an uneven road surface, by rotating and moving the limit control device 200, when the two limit posts 222 on the control sleeve 220 are respectively rotated into the two circumferential slots on the retreat slot 211, the flared mouth 221 at one end of the control sleeve 220 facing the locking slot 212 will be flush with the docking port of the limit sleeve head 210 with the locking slot 212. At this time, the two limit sleeve heads 210 will be released and can move freely, and the limit control device 200 is in an unlocked state. Then, the entire support frame 100 loses the circumferential and longitudinal limits of the limit control device 200. When the support frames 100 on both sides are pressed at different heights, as the user applies downward positive pressure to the support frame 100 through the upper connecting rod 150, the connecting sleeve head 310 on the movable pull rod 300 will compress the spring 2 320, so that a relative displacement in the vertical direction occurs between the two support frames 100, thereby making the entire The walking frame will not tilt to ensure the balance of the user. When the bottom ends of the front supporting leg 120 and the rear supporting leg 140 on one side of the supporting frame 100 are pressed at different heights, as the user applies downward positive pressure to the supporting frame 100 through the upper connecting rod 150, the front supporting leg 120 or the rear supporting leg 140 on this side in the low-lying position will drive the entire supporting frame 100 on this side to rotate relative to the supporting frame 100 on the other side. At the same time, the connecting sleeve 310 on this side will rotate relative to the middle pull rod 330 by compressing the semi-annular spring 340 until the front supporting leg 120 or the rear supporting leg 140 on this side is pressed against the bottom end of the low-lying position. When the walking frame is lifted off the ground, the tilted supporting frame 100 returns to its original position under the action of the semi-annular spring 340 to ensure that when the walking frame walks on uneven roads, the four legs of the walking frame are always in contact with the ground, and there will be no leg-lifting imbalance, thereby ensuring the balance of the user when using it.
