Detailed description of the invention
Those skilled in the art below in conjunction with specific embodiment, technical scheme are described in further detail, so that can be able to implement according to this specification word.
Consulting Fig. 1-3, a kind of draw-bar box, including casing 1, pull bar the 2, first roller 3 and the second roller 4, described pull bar 2 is arranged at the back of described casing 1 and scalable；Described first roller 3 is arranged at casing 1 bottom side, arranges a plurality of；Described second roller 4 is a plurality of, described second roller 4 is for being vertically arranged on bracing frame 5, described second roller 4 relative support frame 5 is freely rotatable, and described second roller 4 and support frame as described above 5 are arranged at the back of described casing 1 jointly, and support frame as described above 5 can rotate by opposite case 1；Folding support bar 6 it is additionally provided with between support frame as described above 5 and described casing 1.
Described casing 1 back is provided with groove 7, and it is internal that described second roller 4 and bracing frame 5 are arranged at groove 7.
Described first roller 3 is 2 or 4.
Second roller 4 is come together out with bracing frame 5 by this draw-bar box in time using on level land, so utilize the nethermost wheel main support point together as supporting box of the first roller 3 and the second roller 4, as long as the main pull bar that somewhat drags just can drive chest forward slip, very laborsaving.
In order to make the result of use of casing better, support bar is when being stretched to maximum length, and the back of its casing and the angle of horizontal plane are 55 degree to 70 degree, and the angle of its bracing frame and horizontal plane is 70-90 degree, and the angle between box back surface and bracing frame is 20-55 degree.
It addition, when draw-bar box is put on or puts stair, it is possible to support bar is folded, second roller is retracted in the groove 7 at casing back, it is shown that wheel protrudes from the outside of casing 1, gets final product upstairs as long as reclining casing 1 to pull up on stair or go downstairs, very laborsaving, as shown in Figure 3.
It should be noted last that, above example is only in order to illustrate technical scheme and unrestricted.Although the present invention being described in detail with reference to embodiment, it will be understood by those within the art that, technical scheme being modified or equivalent replacement, without departure from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of scope of the presently claimed invention.
