Abstract

The invention relates to a crutch, in particular to a Blind person crutch with casters. Rollers are fixed at the lower end of the crutch body. Since the casters are arranged at the lower end of the crutch body, a user only needs to push the crutch forwards when walking and does not need to painfully lift the crutch up from the ground, and energy is saved; and besides, the casters always touch the ground when used for pushing the crutch forwards in walking, and any cavities and even small cavities on the ground can be sensed by the casters, so that potential safety risks can be well eliminated and walking is safe.

Description

The roller type blind-man crutch

Technical field

The present invention relates to a kind of crutch, be specifically related to a kind of roller type blind-man crutch.

Background technology

Traditional crutch is a rod shape structure normally, and the lower end lands, hand-held upper end, and the blind person needs constantly the lower end of crutch to be lifted, put down click ground and explores the way in use, and the hands labor intensity of holding crutch is big, is very easy to tired; On the other hand, clear in order as much as possible the road surface of front to be visited, each clicking point will be tried one's best close, the speed that causes walking can't improve, and because traditional crutch is to adopt the mode of clicking ground, is not continuous, therefore still exist and leak the possibility of visiting, potential safety hazard is arranged.

Summary of the invention

At the deficiency that prior art exists, the object of the present invention is to provide a kind of can adapt to move ahead fast and can not exist to leak visit possible blind-man crutch.

For achieving the above object, the invention provides following technical scheme: a kind of roller type blind-man crutch, comprise the cane body, it is characterized in that: described cane body lower end is fixed with roller.

By adopting technique scheme, because described cane body lower end is provided with roller, the user walking is only with carrying out forward, do not need firmly that cane body lower end is liftoff, so use very laborsaving; In addition, visiting in the process of row forward, roller is permanently connected to ground, has any ditch all can be felt on the ground, even therefore very little hollow can get rid of potential safety hazard well, it is safer to walk.

Below in conjunction with accompanying drawing the present invention is further described.

Description of drawings

Fig. 1 is the specific embodiment of the invention 1 structural representation;

Fig. 2 is the specific embodiment of the invention 2 structural representations;

Fig. 3 is the specific embodiment of the invention 2 decomposition texture sketch maps.

The specific embodiment

Specific embodiment 1: as shown in Figure 1, the roller type blind-man crutch comprises cane body 1, cane body 1 can be to be made of metal tube or metal round rod, cane body 1 lower end is fixed with turning rolls 2, and turning rolls 2 is provided with wheel shaft 201, and roller 3 is installed on the wheel shaft 201, roller 3 can be general plastic wheel, also can be to be made of bearing, adopt the convenient buying of bearing, frictional force be little.

In order to alleviate when crutch is run into barrier the impact to hand, cane body 1 upper end at the roller type blind-man crutch also is provided with a hand grip portion 4, described hand grip portion 4 is provided with the pipe 401 that one section endoporus and cane body 1 upper gap match, pipe 401 inside are provided with and are set in cane body 1 upper end behind the cylinder-shaped compression spring 402 and form the connection that axially can relatively move, pipe 401 is provided with axial long slot bore 4011, cane body 1 is provided with the guiding projection 101 that matches with long slot bore 4011 near upper end, prevent that hand grip portion 4 breaks away from, described compression spring 402 withstands on end, cane body 1 upper end and constitutes the axial elasticity damping piece.

Specific embodiment 2: for some regulation or the frequent circuit of walking, as the sidewalk for visually impaired people etc., can be embedded iron bar at this circuit, for cooperating above-mentioned circuit, can also be provided with magnetic rollers 5 in this roller type blind-man crutch cane body 1 lower end.Shown in Fig. 2,3, in this specific embodiment, comprise a pair of V-shaped left clamping plate 202 and right clamping plate 203 at described cane body 1 lower end turning rolls 2, the center fixed of left side clamping plate 202 and right clamping plate 203 is folded with a bit of sleeve pipe 204 that matches with cane body 1 lower end, described cane body 1 lower end fixedly is plugged in and makes cane body 1 lower end be Y type bifurcation structure in the sleeve pipe 204, and described roller 3 and magnetic rollers 5 are separately positioned on the Y type bifurcated two ends.Described magnetic rollers 5 comprises a bearing 502, two magnetic pieces 503 and two disks 501, described two magnetic pieces 503 are annular, two magnetic pieces 503 are installed in bearing 502 both sides, the magnetic of rolling ring 501 both sides is respectively the N utmost point and the S utmost point, described two disks 501 are separately positioned on two magnetic piece 503 outsides, right clamping plate 203, the two ends of left side clamping plate 202 are equipped with wheel shaft 201, described bearing 502, two magnetic pieces 503 and two disks 501 are set on the same wheel shaft 201, roller 3 is installed on the opposite side wheel shaft 201, left side clamping plate 202 and right clamping plate 203 are separately positioned on two magnetic piece 503 outsides with bearing 502, two magnetic pieces 503 and two disks 501 and roller 3 are connected, the diameter of described two disks 501 rolls to make things convenient for magnetic rollers 5 to be stuck on the iron bar greater than bearing 502, is not easy to depart from.Use has the roller type blind-man crutch of magnetic rollers 5, can find the circuit or the sidewalk for visually impaired people that are provided with the iron bar regulation easily, can accelerate gait of march, has brought more convenience to the blind person.
