Abstract

The utility model discloses a deformed wheel, which comprises a wheel carrier and three small wheels, wherein center of the wheel carrier is opened with installation holes; three struts are evenly arranged in radial direction on the wheel carrier, and the three struts are on a circumference centering on center of the wheel carrier; the wheel carrier is positioned on the axle through installation holes or bearings; rear ends of the three struts are opened with small shaft installation holes, and the three small wheels are respectively mounted on the three struts through small shafts. When provided with the utility model, transport means can easily climb stairs or steps, or round obstacles with less labor requirement; besides, the utility model can also absorb shocks when springs are provided. Therefore, the utility model enables people to conveniently handle goods or wounded persons down from stairs, steps or mountain slopes.

Description

Special-shaped wheel

One, affiliated technical field:

The utility model belongs to a kind of wheel, exactly is a kind ofly can climb the slope of obstacle or the wheel of stair.

Two, background technology:

Along with developing rapidly of building industry, building covers more and more.For the people in the building of living in six, seven floor heights, upper and lower building carrying thing is often very inconvenient.Though the small manual transport trolley can solve the needs of going out and doing shopping, because the wheel restriction can not be gone upstairs.Also have, the baggage container that people use can be portable, can haul is also because the restriction of wheel, and upper and lower step can only be portable, all wants upper and lower step when getting on the bus and get off, and the luggage of band for a long time, and is just very heavy, portable very hard.If also have multi-functional mountain region rescue tool to adopt common wheel, because when last hillside, often run into little ditch or other obstacle should not be walked around, it is very painstaking to walk under the crane cable traction.

Three, summary of the invention:

The utility model is exactly to solve now with the problems referred to above that exist in the technology, a kind of special-shaped wheel is provided, when adopting the small manual transport trolley of this abnormal shape wheel or baggage container or multi-functional mountain region rescue tool etc. to run into obstacle or stair, can easily climb up and over and travel.

For addressing the above problem, technical solution of the present utility model is: a kind of special-shaped wheel, form by wheel carrier and three trundles, the center of wheel carrier has mounting hole, the radial equipartition of wheel carrier has three pillars, and it is on the circumference in the center of circle that three pillars are positioned at the wheel carrier center, wheel carrier by the mounting hole suit or by bearing installation on axletree, the end of three pillars has little axle mounting hole, and three trundles are installed in respectively on three pillars by little axle.

The above-mentioned described pillar of the utility model is made up of inside and outside sleeve pipe, inner sleeve one end is enclosed within the outer tube, is with spring on the inner sleeve outside outer tube, and the inner sleeve other end is divided into two forks, have little axle mounting hole on two forks, trundle passes through little axle mounting on two forks.The two ends that inner sleeve is relative are fixed with the threaded pull bar in upper end, and the corresponding stationkeeping of outer tube has the collar, and pull bar stretches in the collar, is fixed on the outer tube by nut.Like this, can reduce vibrations when wheel moves ahead, make the wounded more comfortable, goods reduces vibrations.

The above-mentioned described pillar of the utility model is straight rod or straight tube also.Straight rod or straight tube end are divided into two forks, have little axle mounting hole on two forks, and trundle passes through little axle mounting on two forks.

The utility model is contained on manpower transport vechicle or baggage container or the multi-functional mountain region rescue tool when travelling on level land and open and flat hillside, and little axle rotation is to overtake in the effect lower edge of pulling force for two trundles that land; When upper and lower stair, perhaps step, when perhaps running into obstacles such as ditch is arranged on the hillside, the front-wheel that lands is subjected to resistance and no longer moves ahead, but as fulcrum, forces the front-wheel rotation of three trundle integral body along ground under tension, climb up by holding on to stair, perhaps step, perhaps behind the cut-through thing, two trundles land and continue to move ahead.Adopt the transportation means of wheel of the present utility model, can climb up by holding on to stair easily, perhaps step, perhaps the cut-through thing is saved manpower, and what spring was arranged has also played cushioning effect.Make people very easily from stair, step or the mountain ripple carrying article or the wounded.

Four, description of drawings

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the structural representation of first kind of embodiment in the utility model;

Fig. 2 is the AA cutaway view of Fig. 1;

Fig. 3 is the structural representation of second kind of embodiment in the utility model;

Fig. 4 is the BB cutaway view of Fig. 3.

Five, the specific embodiment

As shown in Figure 1 and Figure 2, the wheel of present embodiment is made up of wheel carrier and three trundles 1, and the center of wheel carrier has mounting hole, and the radial equipartition of wheel carrier has three pillars, and it is on the same circumference in the center of circle that three pillars are positioned at the wheel carrier center.Wheel carrier is sleeved on the axletree 8 by mounting hole.Pillar is made up of inside and outside sleeve pipe 6,7, inner sleeve 6 one ends are enclosed within the outer tube 7, are with spring 2 on the inner sleeve 6 outside outer tube 7, and inner sleeve 6 other ends are divided into two forks, have little axle 5 mounting holes on two forks, trundle 1 is installed on two forks by little axle 5.Inner sleeve 6 relative two ends are fixed with the threaded pull bar 3 in upper end, and outer tube 7 corresponding stationkeeping have the collar 4, and pull bar 3 stretches in the collar 4, is fixed on the outer tube 7 by nut 9.

As Fig. 1, shown in Figure 3, the wheel of present embodiment is made up of wheel carrier and three trundles 1, and the center of wheel carrier has mounting hole, and the radial equipartition of wheel carrier has three pillars, and it is on the same circumference in the center of circle that three pillars are positioned at the wheel carrier center.Wheel carrier by mounting hole by bearing installation on axletree 8.Pillar is a straight tube 10, and straight tube 10 ends are divided into two forks, has the mounting hole of little axle 5 on two forks, and trundle 1 is installed on two forks by little axle 5.
