Abstract

The utility model relates to a multifunctional trolley. The utility model is characterized in that a handrail 9 can be adjusted by rotation and is fixed by an adjusting screw 10, a tension pulley group 2 which is installed below a trolley beam 1 tenses two wide flat belts 3, an adjusting screw rod 5 tenses the tension pulleys, a limit rotor 6 limits running tracks of the wide flat belts, and the trolley which can goes upstairs and downstairs is formed; a movable sleeve bar 7 is installed on the trolley beam, which can be used for lifting gas bottles or sheathing a trolley hopper to carry goods or sheathing a trolley seat to pull people; the trolley beam is also provided with a short foot group 11 and a long foot group 12, the short foot group and the long foot group touch the ground when the trolley body and the handrail overturn, and the trolley forms a running device.

Description

Multi-functional cart

The utility model relates to the improvement that a kind of going upstairs dolly uses problem, particularly a kind of multi-functional vehicle structure, and it belongs to dolly.

Two groups of formulas of three-wheel of the prior art are drawn gas-jar going upstairs dolly, and in the going upstairs process, wheel constantly is subjected to the antagonistic force of stair wall, and the user must additionally overcome this counter-force.The purposes of car is also less.

The purpose of this utility model is to overcome the problem of above-mentioned existence and provide a kind of more laborsaving, can be used for transporting various things again and send people's stair activity of inconvenience walking.Car is placed on family or the balcony and can works as the treadmill that body-building is used at ordinary times, and the function of car has increased.

The purpose that the utility model proposes is to realize with following technical scheme.

Vehicle structure such as tank, two wide flat rubber beltings for no reason have to be regulated and spacing device, also has straining pulley and support roller formation dolly can adapt to various ground-surfaces and creeps.Wherein there is movable strut member at the two ends of a support roller anchor shaft, can support car at any time on stair in case of necessity and allow the people have a rest.The angle of handrail can be transferred to the operation that is convenient to him by user's height, and wagon box can be put, coal or anything else.Take out wagon box when drawing gas-jar and just can carry gas-jar with loop bar.Wagon box can change people's vehicle seat that the inconvenient people who walks takes into.Wagon box and people's vehicle seat are easy to loading and unloading, are inserted in after loop bar and the self-locking device, go to help to separate to unload and will not deviate from without hand.The bench of people's vehicle seat, pillow, Safety hood can be by people's length displacements, make people's comfortable safety again that is seated, and this is optimum for the hospital that does not have elevator.Car is placed on to be taken down wagon box or people's vehicle seat and takes down loop bar on family or the balcony, and vehicle body and handrail are overturn 180 °, and four pin support vehicle body, and this just becomes the treadmill of body-building.People whenever, and any weather can be taken exercises complacently.Four pin of treadmill contact to earth, and gum cover is arranged is pad, does not have noise, can not influence other people, does not damage ground.

Description of drawings is as follows:

Fig. 1 is the utility model front view.

Fig. 2 is parked in the scheme drawing of stair for the utility model.

Fig. 3 takes patient's scheme drawing for the utility model.

Fig. 4 works as the treadmill scheme drawing for the utility model.

Following the utility model will be further described embodiment in conjunction with the accompanying drawings.

As shown in Figure 1, dolly is the state when the level land, the main wide flat rubber belting 3 of tension force wheels 2 tensionings below car beam 1, and support roller group 4 is being held in the palm wide flat rubber belting 3 simultaneously.Straining pulley is by adjusting screw(rod) 5 tensions, and spacing rotor 6 limits the orbit of wide flat rubber belting 3, and they constitute tank formula car; Loop bar 7 is housed above the car beam 1 can carries gas-jar (Fig. 2-13) again or put wagon box 8, or be inserted in vehicle seat (Fig. 3-17).Handrail 9 and governing screw 10 above the car beam 1, adjustable armrest is in suitable angle.Short pin group 11 and long pin group 12 also are housed on the car beam 1, form the multifunction structure of the forward and backward pin of treadmill, the member formation dolly above (as shown in Figure 4) car beam after these two groups of pin overturn as vehicle body.

Figure 2 shows that the state of gas-jar 13 of carrying of pitching in the stair interval.It is flexible joints that there is the centre of latch 15 securing supports 16,16 alive at anchor shaft 14 two ends, can unidirectional flexing, and do not hinder when making upstairs and advance, stop in case of necessity and just can prop up car; In the time of downstairs, latch 15 changes the another location; Strut member 16 is just shown in line of centers A among the figure.When downstairs also must interval, the strut member 16 support car that can reset.

Figure 3 shows that the state when taking patient, 17 is the people station, and 18 is stretcher, and 19 for being fixed on the sleeve pipe on the stretcher, it can be enclosed within on the

loop bar

7, and 20 is bench, and 21 is Safety hood, 22 is pillow, and they all are to cooperate with tongue-and-groove, scalable front and back position relation and be convenient to loading and unloading.Going up the bar process of going downstairs will have a rest, and also is the effect that relies on strut member 16.

The things such as wagon box, loop bar of not being with shown in Figure 4, only stay short pin and long pin group to also have handrail, vehicle body and handrail turn over a body and install, just become treadmill, it is pad by gum cover all that four pin land, and does not make an uproar, do not decrease ground during motion, and 23 is the flat rubber belting speed regulation device, backguy 24 wrist watch control flat rubber belting speed, handrail 9 can transfer to suitable place.
