Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment one:

With reference to Fig. 1 to Fig. 7, a kind of walker of this embodiment comprises frame body 1, wheel 2 and brake device, and described brake device includes brake handle 3, brake wire and brake block 5, and described car The frame body includes a brake line installation pipe fitting 7, and the two ends of the brake line installation pipe fitting respectively extend to positions close to the brake handle 3 and the wheel 2. The brake handle and the wheel are installed at both ends of the brake line installation pipe fitting. Composed of an inner tube 72 and an outer tube 73, the outer tube is sleeved on the inner tube and can move relative to the inner tube, the brake handle is installed at one end of the inner tube, and a first stopper 74 is inserted and fixed in the outer tube cavity, the first stopper restricts the movement of the inner tube relative to the outer tube, and can be used to stop the inner tube from moving beyond the first stopper relative to the outer tube; a second stopper 75 is inserted into the inner tube , and can move relative to the inner tube, the first stopper and the second stopper are fixed on a fixed rod 79 at a predetermined distance, or a fixed rod 79 is fixed between the first stopper and the second stopper Rod 79; a slider 76, located between the first stopper and the second stopper, fixed at the other end of the inner tube, can slide between the first stopper and the second stopper with the inner tube, The fixed rod 79 passes through the slide block 76, and an operating rod 77 is rotatably installed on the slide block 76 through a support shaft 8. The operating rod extends a support arm 771 and an actuating arm 772 from the position of the support shaft, so The brake line described above is divided into a first brake line section 41 and a second brake line section 42, most of the first brake line section is distributed along the inner cavity of the inner tube, one end of which extends out of the inner tube and is connected to the brake handle, and the other end is connected to the support arm 771. It is used to pull the operating rod to swing along the support shaft. The second brake line segment passes through the slider and is distributed along the inner cavity of the outer tube. One end of it is connected to the second stopper, and the other end is pulled to trigger the braking of the brake block. The actuating arm 772 has A toggle piece 773 for toggling the second brake line section, when the brake handle is activated to cause the first brake line section to pull the operating lever 77 to swing along the support shaft, the toggle piece toggles the second brake line section, and the second brake line is dialed Bending, traction triggers the braking of the brake pads. The slide block is corresponding to the position of the walking path of the second braking line segment, and is provided with several fixed pulleys 78, wherein two fixed pulleys are distributed on both sides of the actuating arm. Since the slider is located between the first stopper and the second stopper, the slider 76 can only move between the first stopper and the second stopper, and the slider 76 is fixed on the inner tube , the first stopper and the second stopper limit the range of movement of the inner tube relative to the outer tube, in order to lock the inner tube, as shown in Figure 3, a positioning hole 82 is provided on the inner tube wall , the outer tube is provided with a lock 83, when the lock 83 is fastened to the positioning hole 82, the inner tube is locked. When adjusting, loosen the lock, the inner tube and the slider move up and down relative to the outer tube for adjustment, the first brake line moves with the inner tube, when the inner tube and the slider move up and down relative to the outer tube, the inner tube and the slider move up and down relative to the fixed rod and the second brake line moves.

In the walker of the present invention, the brake line is divided into a first brake line segment and a second brake line segment which are separated and relatively movable, so that the first brake line can be adjusted up and down with the inner tube, and the height of the brake handle can be adjusted without being affected. The predetermined length of the brake line is constrained, which greatly facilitates the users of the walker.

In the walker of the present invention, the brake wires are arranged inside the brake wire installation pipe fittings, which eliminates the technical problem that the brake wires cause trouble to users.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it can still be Modifications are made to the technical solutions described in the foregoing embodiments, or equivalent replacements are made to some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
