detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, a walking aid includes two bottom bars 1 parallel to each other, universal rollers 2 are provided on the front and rear bottom surfaces of each bottom bar 1, and the front ends of the two bottom bars 1 are connected. There is a cross bar 110, two telescopic vertical rods 3 are respectively hinged on the top surfaces of the front ends of the two bottom rods 1, two mutually parallel struts 4 are respectively slidably connected with the bottom rod 1 and the telescopic vertical rod 3 on the same side, The sliding connection is provided with a locking device, a pull rod 41 is connected between the two struts 4, and a supporting platform 5 is provided on the upper part of the telescopic vertical pole 3, and the supporting platform 5 is respectively connected with the upper parts of the two telescopic vertical poles 3, The support platform 5 has a U-shaped groove opening backward, and the top surface of the support platform 5 is provided with two handles 11, and the telescopic pole 3 top is also provided with an infusion stand 6.

As shown in Figures 5-6, the telescopic pole 3 is a telescopic telescopic pole, and the telescopic pole includes a lower sleeve 31 and an upper sleeve 32 sleeved outside the lower sleeve 31 , the lower sleeve 31 is provided with a threaded hole 311, the upper sleeve 32 is provided with a knob 7, and the upper sleeve 32 is also provided with an elongated notch 321 along its axial direction, the knob 7 includes a screw rod 71, a concave platform 72 And the button plate 73; the screw rod 71 is adapted to the threaded hole 311, the concave table 72 has a side wall adapted to the outer wall of the upper sleeve 32, the side wall has a light hole, the front end of the screw rod 71 passes through the light hole, and the length The bar-shaped notch 321 is connected with the threaded hole 311 behind, and the knob plate 73 is connected with the root of the screw rod 71 .

As shown in Figure 2-4, the outer walls of the two bottom bars 1 and the two lower sleeves 31 are provided with slide grooves 8 along the respective axis directions, and the two ends of the two struts 4 are provided with corresponding There is a slider 9 that is compatible with the chute 8, and the slider 9 is hinged with the strut 4; There are several holes 81 on the side wall, and any one of the holes has a coaxial hole opposite to it, and the distance between two adjacent holes 81 is equal. When the slider slides in the chute, the holes 81 and the through holes The axes of the holes 91 are parallel to each other and in the same plane, and the pin 10 passes through the through hole 91 and the hole 81 to fix the slider 9; a large number of holes 81 on the side wall of the chute 8 can ensure that the strut 4 has multiple positions, Correspondingly, the angle between the bottom bar 1 and the telescopic upright bar 3 has an adjustable function.

When in use, the user pulls out the pin 10, adjusts the angle between the bottom bar 1 and the telescopic upright bar 3 by adjusting the positions of the sliders at both ends of the support bar 4, and after selecting a suitable angle, puts the pin 10 through the The hole 81 and the through hole 91 are used to fix the support rod 4 and the telescopic vertical rod 3; then turn the knob 73 according to the needs of the user, pull out or press in the upper sleeve 32 inserted outside the lower sleeve 31, At this time, the knob 7 moves relative to the notch 321.
