Description
Technical field
The utility model is related to Foldable luggage vehicle, more particularly to a kind of baggage that small good hand touch is fluctuated when climbing building
Car, belongs to luggage truck technical field.
Background technology
Luggage truck is the common tool of people's trip, when going on business, travelling or going shopping, by some things of luggage vehicle-mounted running
When product or goods people with regard to it is free and relaxed more, however, with the development of society, high buildings and large mansions are more and more, many multilayer knots
The building of structure does not have elevator can use, and it can not climb building well for the traditional luggage truck that can only be walked on level land, then,
The continuous utility model of people is created, and many that come out is deformable just as crawler belt stairs-mover, three leaves or the star-like wheel stairs-mover of five leaves
Building climbing wheel, electric stairs-climbing wheelchair, and apish the step progressively hydraulic pressure of foot-up or electric stair climbing device etc..
The advantage of above-mentioned crawler belt stairs-mover is stationarity and smoothly to feel, and can be adapted to a variety of corridors, have the disadvantage it is complicated,
Manufacturing cost is very high, and radius of turn is larger, underaction, is primarily adapted for use in military affairs, anti-terrorism, public security, fire-fighting and the disaster relief etc. special
Occasion, is not suitable for popularization among the people；The people that three leaves or the star-like wheel stairs-mover of five leaves are bought at present is a lot, and advantage is simple in construction, system
Cause that this is very low, wheel shape is easy to carry without conversion, when having the disadvantage to climb building above and below fluctuate, feel extreme difference is firmly irregular,
Vibration is very big, and noise is very loud, uses very uncomfortable；Electric stairs-climbing wheelchair, the hydraulic pressure of apish step foot-up electronic are climbed
The advantage of building device be stationarity preferably, it is laborsaving to climb building, has the disadvantage that volume is larger, acquisition expenses is higher, slow in action, not easy to break
It is folded, it is not portable.
In existing license or patent application, Application No. 200910071294.6 and 201110186237.X patent
It is that advantage is that wheel can be deformed with the smooth stairs-mover felt and continuously felt, feel is very well, firmly uniform when climbing building, fluctuation
Very little, has the disadvantage that car wheel structure is complicated, manufacturing cost is higher, needs to turn wheel shape building from level walking to climbing
Change, if having multi-layer stair in corridor and there are multiple platforms to need transition therebetween, then such stairs-mover needs constantly to stop pair
Wheel enters line translation, and transport pauses, taken time more, very inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of small volume, and cost is relatively low, rotates flexible, radius of turn very little,
From level walking to climbing building without be deformed to wheel, exerted oneself when climbing building uniform, fluctuate small, good hand touch, can be laborsaving, easily
In folding, portable stairs climbing suitcase trolley.

10. according to Figure 10, the upper six sons wheel of son wheel envelope (L) its shape and length and son wheel clamping plate (16) of arc
The position of axle (17) is to be determined according to the size of actual stair using per-spot way, and the length of sub- wheel envelope (L) is equal to
The normal width of residential building stair is 250 millimeters, is that the sub- wheel shaft in valley point (B) to summit is taken turns along main wheel leaf (12) straight line
The calibrated altitude that the son wheel difference in height (H) of axle (A) is equal to residential building stair is 160 millimeters.
11. because six sub- wheel shafts (17) of the sub- wheel shaft in valley point (B) to the sub- wheel shaft in summit (A) and the distance of main shaft (13) are
Increased successively, six son wheels (18) of the sub- wheel shaft in valley point (B) to the sub- wheel shaft in summit (A) contact stair successively, so climbing building
When, the height of main shaft (13) is by lifting step by step, and this is the reason for luggage truck fluctuates small when climbing building；Due to climbing power thrusts during building
It is sideling upward, and due to arc wheel envelope (L), power thrusts and horizontal angle are larger, add top
The son wheel (18) at idea wheel shaft (A) place is present, and stair vertical edges is diminished the obstruction power of wheel, this is luggage truck when climbing building
Firmly less cause.
12. the son wheel (18) at summit sub- wheel shaft (A) place is both used as level walking, also serves as and reduce son wheel clamping plate when climbing building
(16) abrasion of the summit wedge angle to stair, to reduce on the outside of noise when luggage truck climbs building, sub- wheel (18) provided with one layer of wear-resisting rubber
Glue, when implementing main wheel leaf (12) and son wheel clamping plate (16), is taken pictures to Figure 10 with digital camera, liquid crystal projector is used after input computer
It is imaged on blank sheet of paper, distance or regulation zoom button between regulation projector and blank sheet of paper when image meets given size, use black pen
Described on blank sheet of paper along projection image, you can obtain 1:1 implementation drawing.
13. because the lines of drawing are more closeer, to make figure concise, even hook (10) and iron chains (26) do not have for setting
Drawn in Fig. 2 into Fig. 4, the material of main body of vehicle frame is stainless steel, and the material of wheel body is aluminium alloy, axle sleeve (14)
Material is high-quality steel pipe, and the material of main shaft (13) is hard without line reinforcing bar.
