Abstract
The utility model relates to a guide cane and pertains to an assistant tool for walking of the blind, which adopts a gear drive and a four-bar linkage. The gear drive consists of a T type shaft (10), a large bevel gear (12), and a small bevel gear (11). In which, the small bevel gear, actually a pair of conical gears, rotates together with the wheel; the four-bar linkage consists of a long pole (17), a positioning screw (18), a short pole (20), and a short pole bolt (23) used for connecting the short pole and the brim of supine surface of the T type shaft, which takes the distance from the short pole bolt to the T type shaft center as a crank, the short pole as a connecting pole, the long pole as a horizontal swing stem, and the part from the T type shaft center to the positioning screw as a hack lever. The cane is connected with the four-bar linkage by means of the rack and the gear drive. The utility model operates the four-bar linkage operate by driving the wheel with the swing of the long pole as the output, so that the long pole stops moving when confronting barriers, which further causes the wheel to stop moving, and thereby brings convenience for the blind to try out and walk.
Description
Technical field
This utility model relates to a kind of blind-guiding stick, utilizes quadric chain and bevel gear to realize the function that helps the people with disability to explore the way, and belongs to the aid of blind person's walking.
Background technology
Present blind man's stick has two kinds of traditional blind man's stick and electronics blind man's sticks, and traditional blind man's stick is simple in structure, but needs could use through strict training, uses very inconvenient.Though the electronics blind man's stick is easy to use, costs an arm and a leg.
Summary of the invention
The purpose of this utility model be propose a kind of easy to use, safe, the blind-guiding stick that user does not need to train and cost is low.
Thereby this utility model drives wheel by the hand propelled blind-guiding stick rotates gear, change the direction of motion by bevel gear, and the drive quadric chain, the swing by stock finally reaches the purpose of eliminating illiteracy, and the concrete technical scheme of employing is: comprise walking stick 1, gear drive part and quadric chain.The bottom of walking stick 1 is connected with frame 9, and frame 9 is connected by the axle 14 that pair of bearings 13 and both sides have wheel respectively.
Gear drive part is by T profile shaft 10, with T profile shaft 10 close-fitting bevel gear wheels 12, form with the bevel pinion 11 of bevel gear wheel 12 engagements, described bevel pinion 11 closely cooperates with axle 14 and axle 14 rotates, and bevel gear wheel 12 is a pair of bevel gear with bevel pinion 11.
Consisting of of quadric chain: stock 17 links to each other with positioning screw 18, quarter butt 20 and stock 17 link together, quarter butt 20 links to each other by quarter butt bolt 23 with the edge of T profile shaft 10 upper surfaces, wherein, distance with quarter butt bolt 23 to T profile shafts 10 centers is a crank, quarter butt 20 is a connecting rod, and stock 17 is horizontal fork, and T profile shaft 10 centers are the frame bar to the part of positioning screw 18.
Described walking stick 1 closely cooperates with angle adjustment draw-in groove 2, and angle adjustment draw-in groove 2 links to each other with hexagonal angle adjustment nut 5, and angle adjustment draw-in groove 2 connects the groove of 12 limit types in being, it can do 30 angle adjustment of spending with respect to angle adjustment nut 5.
Described each wheel 16 closely cooperates with a pair of sleeve 15, and drives bevel pinion 11, constitutes the power transmissioning part branch.
Design principle of the present utility model is: 1, the gear of Shi Yonging is a pair of bevel gear, because wheel 16 drives bevel pinion 11 motions, by the rotation of engagement with vertical-horizontal, changes into the rotation of parallel, horizontal like this; 2, four push and pull system when bevel gear wheel 12 drives 10 rotations of T profile shaft, are rotated drive quarter butt 20 thereby be equivalent to crank, and then are driven stock 17, make its swing.
In addition, angle adjustment draw-in groove 2 is the grooves that connect 12 limit types in, because angle adjustment 5 nuts are hexagonal, so it can do the angle adjustment of 30 degree with respect to angle adjustment nut 5.
This utility model finally makes the motion of four push and pull system by promoting wheel, is output with the swing of stock, when running into barrier,, its motion is ended, thereby ended gear movement because stock passive movement thing hinders, and then wheel can not move yet, and can make the blind person know the road conditions in the place ahead like this.This utility model is easy to use, and cost is low.

The specific embodiment
Further specify specific embodiment of the utility model below in conjunction with accompanying drawing.
Blind-guiding stick integral body in the present embodiment is divided into five parts: the walking stick part, and rack section, gear drive, power transmissioning part divides and quadric chain, referring to Fig. 1, Fig. 2 and Fig. 3.The order of connection of each several part is followed successively by: walking stick 1 and angle adjustment draw-in groove 2 tight fits, and these two parts have constituted the walking stick part; Adjust draw-in groove 2 and link to each other with angle adjustment nut 5, adjust nut 5 and be welded on the frame 9, welding back-up ring 6 and welded nut 7 are welded on the frame 9, be used for fixing the angle adjustment nut, hold-down nut 3 and fixedly back-up ring 4 be used, be used to step up angle adjustment draw-in groove 2, and can dismantle easily; These parts have been formed rack section jointly; Frame 9 also links to each other with locating wheel 8, is used to guarantee that frame is parallel to the ground; T profile shaft 10 and bevel gear wheel 12 closely cooperate, bevel pinion 11 and bevel gear 12 engagements, and these three parts have constituted the gear drive part; Bevel pinion 11 closely cooperates with axle 14 and is in the same place, so that associated movement, axle 14 and pair of bearings 13 closely cooperate, and axle 14 and cover bucket 15 closely cooperate, and cover bucket 15 and wheel 16 closely cooperate, and constitute the power transmissioning part branch; Stock 17 is hinged and connected with positioning screw 18, setscrew nut 19 links to each other with positioning screw 18, quarter butt 20 and stock 17 link together by stock nut 21 and bolt of long stem 22, quarter butt 20 and T profile shaft 10 link together by quarter butt bolt 23 and quarter butt nut 24, and these parts have been formed quadric chain jointly.
