The specific embodiment

See also Fig. 1, the utility model first Application Example shown in 2, this casing of being convenient to tow 100 is by one case body 10, one pull bar group 20, second wheel 30, one auxiliary wheel 40, one drawstring 50 and a coiler 60 constitute, above-mentioned case body 10 also is made up of the plastic cement drain pan 11 of a hard and the upper cover body 12 of a cloth matter, between its grade with a side serve as articulate to link make this upper cover body 12 relatively this drain pan 11 for starting or involutory, again, above-mentioned pull bar group 20, roller 30, auxiliary wheel 40, drawstring 50 is installed on the precalculated position of this drain pan 11 together with coiler 60, and the relevant position of its grade and structure narration are then asked for an interview in aftermentioned:

At first, the drain pan 11 of this case body 10 is made up of with a base plate 115 front side board 111, a back side panel 112, a left side (right side) side plate 113 (114), be concaved with a handle tank 116 in front side board 111 and base plate 115 junctions, in back side panel 112 with base plate 115 junctions and be positioned at two outsides and then be concaved with a roller tank 117 respectively, again, this base plate 115 is in the circular tank 118 that has inner recess on one day near a place of front side board 111, and this tank 118 also is angular position with this second wheel tank 117 and distributes and be provided with.

This pull bar group 20 has this front side board 111 and be the handle 21 that extract out to use relatively, and when not using this pull bar group 20 at ordinary times, this handle 21 is to place in this handle tank 116, because pull bar group 20 belongs to general structure, so repeat no more in this.

The axle pivot is in the roller tank 117 of correspondence respectively for this second wheel 30, and its grade is the two side places that are positioned at these drain pan 11 1 edges, and the wheel face of these rollers 30 is exposed to the back side panel 112 and base plate 115 outsides of this drain pan 11.

This auxiliary wheel 40 utilize a latch 41 to wear and the axle pivot on a discoidal wheel seat 42, aforementioned wheel seat 42 also is installed in the tank 118 of this base plate 115, and this wheel seat 42 be able to that its axle center is fixed and in tank 118 original place rotate, again, this latch 41 is to wear with the shaft core position of stray circle dish type wheel seat 42, when its auxiliary wheel 40 that makes wheel face be exposed to this wheel seat 42 and these base plate 115 outsides rolls in contacting to earth, can tow the change of direction and this wheel seat 42 of interlock produces and turns to arbitrarily with work casing 100, more smooth and easy so that casing 100 tows.

This drawstring 50 is used in combination with coiler 60, this coiler 60 is hidden the medial surface of being located at this front side board 111, its inside is provided with the wind spring (not shown), and these drawstring 50 1 terminations are located at arrow and are stated on the wind spring, the other end then is provided with a head 51 after passing this front side board 111, make this head 51 be positioned at the lateral surface of front side board 111, the user is able to hand and holds by this head 51 and this front side boards 111 and pull out drawstring 50 and use with dilatory casing 100 relatively, and when this head 51 of hand pine oil, this drawstring 50 by wind spring automatically volume be hidden in the coiler 60.

More than be casing 100 each member that the utility model is convenient to tow and the explanation of associated location thereof, then, please consult shown in Figure 3 earlier, first kind of user mode schematic diagram for the utility model casing 100, as shown in the figure, the user is able to relative these front side boards 111 of this handle 21 are extracted out, is contacted to earth simultaneously by this second wheel 30 again, and it is casing 100 to tilt to be inverted and for being dragged to arbitrary position;

See also second kind of user mode schematic diagram of Fig. 4 again, this casing 100 is flat on the ground, its drain pan 11 ground proximitys, this handle 21 is placed in this handle tank 116, this second wheel 30 contacts to earth simultaneously with this auxiliary wheel 40, and owing to above-mentioned three wheel bodys are possessed preset distance to each other and are angular distribution, therefore this casing 100 is steadily put and can not be produced beat and rock, at this moment, user's hand is pulled out these drawstring 50 heads 51, is dragged this casing 100 like a cork by the belt body elongation.

In addition, see also shown in Figure 5 again, the casing 200 of present embodiment has the plastic cement drain pan 201 of a hard and the upper cover body 202 that a cloth matter is made, these upper cover body 202 end faces are provided with two belts 203 (or a carrying handle), and this upper cover body 202 also has an extensible or body portion 204 that condensation changes, be equipped with a few slide fastener 205 structures in this body portion 204, the pulling track of this slide fastener 205 is along these body portion 204 side face settings, when slide fastener 205 is opened, this body portion 204 is stretched and is increased the inner space of this casing 200, as shown in Figure 5, casing 200 is kept flat and is supported in ground with three wheel bodys, so, the user must lift this belt 203 to drag this casing 200, otherwise during with slide fastener 205 drawings, then contract in casing 200 inner spaces.

Again, aforementioned belt 203 is able to the mode that can pull down or assemble and is used in combination with casing 200, and the structure with manner that is for example disclosed in Fig. 5 promptly is.

The above only is a preferable possible embodiments of the present utility model, uses the equivalent structure variation that the utility model specification and claim are done such as, ought to be included in the claim of the present utility model.
