Abstract

The utility model relates to a universal antiskid crutch, which comprises a crutch tube and the rubber crutch sleeve on the crutch. The utility model is characterized in that a universal rolling device is added between the crutch tube and the rubber crutch sleeve, and the problem that the crutch used by the handicapped is easy to glide is solved; thus, however the variation of the included angle between the central line of the crutch and ground is, the bottom face of the crutch can be automatically put flat in the process of the walking of the handicapped; thus, the full contact with the ground can be kept, which makes friction increase, and skid-proof effect is achieved; the utility model offers guarantee for the walking of the handicapped; besides, the universal rolling device has simple structure, easy manufacture, and the popularization and use meaning by replacing the existing crutches.

Description

Universal antiskid crutch

This utility model belongs to a kind of people with disability's articles for use, the universal anti-skidding head that turns on the crutch that particularly a kind of lower limb disability people uses.

The crutch of people with disability's use at present is comparatively original, only puts a rubber sleeve in the lower end of button cane, in the hope of playing anti-skidding effect.But the area diameter is less because existing rubber sleeve lands, corresponding frictional force is also less, skid easily, rubber sleeve is fixedly to be placed in crutch tip simultaneously, when crutch stretches to the front in advancing, the lower surface and the ground of turning head form angle, and then crutch and ground become an intimate some contact form, cause contact area littler, easier skidding, can bring inevitably serious calamity to the people with disability thus, as fall down traumatic injury, so that bigger danger takes place, as seen, the easy cunning of improving the people with disability turns head, is an important topic that ensures lower limb disability people walking along the street safety.

The purpose of this utility model is to provide a kind of universal anti-skidding head that turns, it is solved the easily sliding problem of the used crutch tip of people with disability conscientiously, how the centrage that no matter turns in people with disability's walking along the street process and the angle on ground are changed, can make and turn a bottom surface and set level automatically, to keep itself and the contacting fully of ground, cause increase frictional force, reach skidproof effect, improved people with disability's walking along the street safety coefficient.

The technical solution of the utility model: a kind of universal anti-skidding head that turns, comprise turn head pipe and on rubber turn headgear, it is characterized in that having installed a univesal wheelwork additional between above-mentioned two structures, this device is by the tapped platform that connects, back-moving spring, adjust the locknut of back-moving spring, the back-moving spring holder, movable spheroid, the hemisphere train wheel bridge, hemisphere lower plate and running through, the screw of lower plate and latch bracket, nut is formed, said tapped connect platform insert turn in the head pipe fixedly connected according to the riveting pin, the activity ball centre is given and is buried a bolt that stretches out outside the spheroid, spheroid is seated between hemisphere train wheel bridge and the hemisphere lower plate, give the bolt that buries on the spheroid and pass the hemisphere train wheel bridge, the back-moving spring holder, back-moving spring, the locknut of adjusting back-moving spring becomes to be threaded with the tapped platform that connects, said running through, the screw of lower plate and latch bracket gives and is embedded in rubber and turns in the headgear upper port, it is one that the hemisphere lower plate also turns the headgear crimping with rubber, cover the hemisphere lower plate on the screw successively, the hemisphere train wheel bridge, automatically regulate the stage clip of thrust, the back-moving spring holder, its outer end is fastening by nut.

Operation principle of the present utility model and use: at first adjust stage clip and make movable spheroid last, can freely reset between lower plate, back-moving spring above the then movable spheroid can make the head that turns that changes angle because of walking, before next step kiss the earth, the position of the central lines of getting back to and turning, to guarantee next step accurate and good coincideing of ground maintenance, promptly how the angle of cut on centrage that no matter turns and ground changes, all can make it after turning a kiss the earth, the weight of the person be added in turn built on stilts people before, since body weight make turn the head can set level automatically, keep contacting with the complete of ground, can increase its frictional force greatly like this, reach good anti-skidding purpose, increased safety factor for people with disability's row step and life.

Superiority of the present utility model is: 1, be skillfully constructed, can assist the people with disability in making the walking process that turns, increase frictional force, prevent to turn head and skid, provide assurance safely for the people with disability walks; 2, simple in structure, be convenient to manufacture, have the existing meaning that turns head and generally promote the use of of replacement.

Further specify present technique below in conjunction with drawings and Examples.

Accompanying drawing 1 for this utility model related universal anti-skidding turn head partly cut open structural representation.

Accompanying drawing 2 is the vertical view of back-moving spring holder among Fig. 1.

Wherein 1 for turning the head pipe, and 2 is rivet, and 3 are the tapped platform that connects, 4 for adjusting the locknut of back-moving spring, and 5 is back-moving spring, and 6 is the stage clip of regulating thrust automatically, 7 (give on the spheroid and bury a bolt for movable spheroid, with 3,4 be connected), 8 is the back-moving spring holder, 9 for running through screw, the nut of second splint and latch bracket, 10 is the hemisphere train wheel bridge, 11 is the hemisphere lower plate, and 12 for rubber turns headgear, and 13 is the cast groove.

Embodiment: an a kind of universal anti-skidding (see figure 1) that turns, comprise and turn head pipe 1 and rubber turns headgear 12, it is characterized in that between above-mentioned two structures, having installed a univesal wheelwork additional, this device is by the tapped platform 3 that connects, back-moving spring 5, adjust the locknut 4 of back-moving spring, back-moving spring holder 8, movable spheroid 7, hemisphere train wheel bridge 10, hemisphere lower plate 11 and running through, the screw of lower plate and latch bracket, nut 9 is formed, said tapped connect platform insert turn in the head pipe fixedly connected according to rivet 2, the activity ball centre is given and is buried a bolt that stretches out outside the spheroid, spheroid is seated between hemisphere train wheel bridge and the hemisphere lower plate, give the bolt that buries on the spheroid and pass hemisphere train wheel bridge 10, back-moving spring holder 8, back-moving spring 5, the locknut 4 of adjusting back-moving spring is threaded for 3 one-tenth with the tapped platform that connects, said running through, the screw 9 of lower plate and latch bracket gives and is embedded in rubber and turns in headgear 12 upper port, it is one that hemisphere lower plate 11 also turns headgear 12 crimping with rubber, cover hemisphere lower plate 11 on the screw 9 successively, hemisphere train wheel bridge 10, automatically regulate the stage clip 6 of thrust, back-moving spring holder 8, its outer end is fastening by nut.

Above-mentioned rubber turns can the sipe cast groove 13 as shown in the figure that increases frictional force on the headgear bottom face.

3-5 hole that supplies screw 9 to pass can be arranged in the back-moving spring holder, and identical quantity is also got in the hole on spiral shell pin 9 correspondingly, stage clip 6 and the upper and lower clamping plate 10 and 11, and present embodiment is 4 holes as shown in Figure 2.
