Embodiment
The present invention is further described with reference to the accompanying drawings and examples, and the content of embodiment is not as the guarantor to the present invention
Protect the limitation of scope.
Fig. 1 shows the axonometric drawing of the buggy of the energy speeling stairway of the present invention.Fig. 2 shows that the present invention's can climb building
The front view of the buggy of ladder.
As illustrated in fig. 1 and 2, the buggy of energy speeling stairway of the invention includes chassis 1 and vehicle frame 2.Wherein, the vehicle frame
2 bottom is connected by rotating shaft 7 with the bottom of the chassis 1, so that the vehicle frame 2 can be relative to the chassis 1 in position of lying down
Put and rotated between cocked position.Preferably, the vehicle frame 2 is provided with grab, when in lie down position when, the vehicle frame 2 is logical
The grab is crossed to be buckled on the chassis 1 and be combined together with the chassis 1.Wherein, when in cocked position, it is used for
The goods A of setting is bundled on the vehicle frame 2.When in lie down position when, for moving the buggy, with movement be bundled in
Goods A thereon.
The vehicle frame 2 is provided with restraint of loads A bundle chain 3.The goods A is bundled in by the car by the bundle chain 3
On frame 2.Preferably, the vehicle frame 2 is provided with the two restraint of loads A bundle chain 3.It is in such manner, it is possible to the goods A is more firm
Admittedly be bundled on the vehicle frame 2.It is highly preferred that the bottom of the vehicle frame 2 is additionally provided with the supporting plate 8 for holding the goods A.This
Sample, that is, it is easy to the goods A being attached on the vehicle frame 2, can more prevents the goods A from being dropped from the vehicle frame 2.
The upper end of the vehicle frame 2 is provided with acclivitous handle 4.The buggy is pulled to advance by the handle 4.It is described
Handle 4 is provided with ratchet 5.Preferably, the handle 4 is provided with two ratchets 5, and two ratchets 5 are symmetrically set
Put in the both sides of the handle 4.Because the handle 4 is inclined upwardly, when can ensure to encounter stair during buggy traveling, in institute
State the power produced on the ratchet 5 on handle 4 obliquely.
In addition, the general slope of stairs is about 25 degree, foot-operated face width is about 32 centimetres, across about 14 centimetres of height, is such as carried
The gas bomb of hospital or scientific research institutions is generally 40 liters of specifications, and about 1450 millimeters of height, diameter is about 219 millimeters, weight
About 50 kilograms or so, that is to say, that tilting will not topple within 80 degree.Therefore, in the present invention, the length of the chassis 1 will
More than 1500 millimeters, width is greater than 250 millimeters, and the inclination angle of the handle 4 will just can guarantee that small goods about at 25 degree
The easy stair climbing of appearance of vehicle is not easy to topple over.
The chassis 1 is provided with multiple ratchets 5.Preferably, the chassis 1 is provided with six ratchets 5.More preferably
Ground, every side of the chassis 1 is designed with three ratchets 5 and the ratchet 5 of the both sides of the chassis 1 is symmetrical arranged.
When being advanced on level ground, advanced by six ratchets 5 set on the chassis 1；When running into stair
When, as shown in Figures 3 and 4, under the collective effect of the ratchet 5 on the ratchet 5 and the chassis 1 on the handle 4
Advance.
In the present invention, the ratchet 5 is similar with the structure of ball type unidirectional clutch.As illustrated in figs. 5-7, the ratchet
5 include centre wheel 5-2.The centre wheel 5-2 is arranged on bearing 6.For example, the centre wheel 5-2 can be set by its both sides
The support shaft put is arranged on the bearing 6.The bearing 6 is arranged on the chassis 1 or shaken hands on 4.Each ratchet 5
It is required for configuring a bearing 6.
The centre wheel 5-2 is installed in outer shroud 5-1 by two mounting ring 5-5.Wherein, the inner surface of the outer shroud 5-1
On be provided with the open slot 5-1-1 of multiple cam type wire types.Preferably, multiple open slot 5-1-1 are along the outer shroud 5-1
Inner periphery equably set.
In the present invention, the bottom surface of the open slot 5-1-1 is cam profile surface, makes it have big end and small end, and
With wedging angle.And, it is preferable that the angle at the wedging angle is 6-8 degree.
Also, compression spring 5-3 one end is fixed in the big end of the open slot 5-1-1.Preferably, in the big end
Groove with the one end for accommodating and fixing the compression spring 5-3.The other end connection ball 5-4 of the compression spring 5-3.
In the course of work, if the outer shroud 5-1 is rotated in the counterclockwise direction relative to the centre wheel 5-2, then, it is described
Ball 5-4 is just mobile to big end in the open slot 5-1-1 with cam profile and compresses the compression spring 5-3.This
When, the ratchet 5 is not in locking phenomenon, and allows the outer shroud 5-1 to rotate, as shown in Figure 6.That is, shown in Fig. 6
The ratchet 5 in free state allow the outer shroud 5-1 to make the inverse time relative to the centre wheel 5-2 at any time
Pin rotates.It is said differently, that is, allows the centre wheel 5-2 to be rotated clockwise relative to the outer shroud 5-1.
But in the course of the work, if the outer shroud 5-1 of the ratchet 5 is attempted relative to the centre wheel 5-2 along up time
Pin direction rotates, then, the ball 5-4 is just moved in the open slot 5-1-1 to small end, wedges the centre wheel 5-2
Between the outer shroud 5-1, both are pinned, at the same time, moment of torsion can also be transmitted therebetween.This moment, the compression
Spring 5-3 effect is to improve the initial wedging actions of the ball 5-4, once the ball 5-4 wedges the open slot 5-
1-1 small end, then there is locking in the ratchet 5, so as to not allow the outer shroud 5-1 to make up time relative to the centre wheel 5-2
Pin rotates, or the centre wheel 5-2 rotates counterclockwise relative to the outer shroud 5-1, as shown in Figure 7.
In addition, in the present invention, it is preferred to, the outside of the outer shroud 5-1 is also arranged with rubber tyre 5-6.So so that
The ratchet 5 can simulating vehicle tire, in order to preferably upwards traveling.
When meeting stair T, it is first about the rotating shaft 7 and rotates the vehicle frame 2, makes the vehicle frame 2 relative to the bottom
Frame 1 is in position of lying down.Then, the vehicle frame 2 and the chassis 1 are fixed together.Then, as shown in Figures 3 and 4, it is described
Ratchet 5 on handle 4 produces thrust obliquely, and now the ratchet 5 on the handle 4 turns clockwise, and makes the buggy
Slowly lift, the effect with regard to speeling stairway T can be played.When continuing climbing, the ratchet 5 on the chassis 1 also produces obliquely
Thrust, now the ratchet 5 on the chassis 1 also turn clockwise, the buggy just is lifted, reach and preferably climb
Stair climbing T effect.
When buggy climbs to stair center section, if staff needs to rest, now buggy is while in inclination
State, the ratchet 5 can be now set to be in locking state, at this time, buggy is with staircase equivalent to sliding friction, friction
Power is far longer than force of rolling friction when climbing, therefore buggy is not easy to slide, and drastically increases security.
The above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not to the present invention
Embodiment restriction.For those of ordinary skill in the field, can also make on the basis of the above description
Other various forms of changes or variation.Here all embodiments can not be exhaustive.Every skill for belonging to the present invention
Row of the obvious changes or variations that art scheme is extended out still in protection scope of the present invention.
