The fixed idler whell of body bottom surface；Described fixed idler whell is two, and two described fixed idler whells are symmetrically positioned in the front portion of tank floor；
The bottom surface of described casing is additionally provided with scalable wheel；Described scalable wheel is be symmetrically positioned in tank floor rear portion two；Institute
The bottom surface stating casing is fixed with the fixing chute of corresponding described scalable wheel setting；Described tie-bar case also includes can be in institute
Slide in the fixing chute stated and realize flexible movable sliding；Described scalable wheel is fixed in described movable sliding, structure
The scalable wheel becoming described can realize the flexible structure of scalable wheel with slip chute along described fixing chute movement.
One end of described movable sliding is connected with described fixing chute by extension spring.
It is hinged with rotatable lock pin block in described fixing chute；Corresponding described lock pin block is in described slip chute
On be provided with and touch bearing pin；Described touch bearing pin and the cooperation of described lock pin block and collectively form in order to take turns into line-locked to scalable
Locking mechanism.
Described fixing chute be lower surface opening concave shape structure, the side wall of described fixing chute has in order to
The short slot that lock pin block slides.
Described movable sliding is the concave shape structure of upper surface opening, and the side wall of described movable sliding 9 has use
The short slot being slided with lock pin block.
The back side of described casing is provided with the draw-in groove in order to suitcase and draw-bar box to be assembled into one.
The utility model proposes a kind of draw-bar box with telescopic wheels, in bottom half, scalable wheel, the pull-out of scalable wheel are set
Afterwards, when tilting to pull draw-bar box, draw-bar box is just moved with the contact point on ground to outside the dorsal part of draw-bar box, is equivalent to have raised and draws
The center of gravity of bar case, it is to avoid the case and bag of draw-bar box dorsal part touch ground, and have the characteristics that easy to use, low cost of manufacture.
Brief description
Fig. 1 is the utility model structural representation.
Fig. 2 is scalable wheel of the present utility model and fixing chute, the attachment structure schematic diagram of movable sliding.
The inclination that Fig. 3 loads suitcase for the utility model pulls schematic diagram.
In figure：1st, casing, 2, pull bar, 3, fixed idler whell, 4, scalable wheel, 8, fixing chute, 9, movable sliding, 10, draw
Spring, 11, lock pin block, 12, touch bearing pin, 13, suitcase.
Specific embodiment
In conjunction with the drawings and specific embodiments, the utility model is illustrated：
As shown in figure 1, a kind of draw-bar box with telescopic wheels, described draw-bar box includes casing 1, is arranged on casing 1 back side
Pull bar 2 and the fixed idler whell 3 being located at tank floor；Described fixed idler whell 3 is two, the symmetrical position of two described fixed idler whells 3
Front portion in casing 1 bottom surface；The bottom surface of described casing 1 is additionally provided with scalable wheel 4；Described scalable wheel 4 is to be symmetrically positioned in
Two of casing 1 bottom surface rear portion；In conjunction with Fig. 2, the bottom surface of described casing 1 is fixed with the fixation of corresponding described scalable wheel setting
Chute 8；Described tie-bar case also includes to slide in described fixing chute 8 realizes flexible movable sliding 9；Described
Scalable wheel 4 is fixed in described movable sliding 9, and constituting described scalable wheel can be with slip chute along described fixing cunning
The flexible structure of scalable wheel is realized in groove movement.
One end of described movable sliding 9 is connected with described fixing chute 8 by extension spring 10.
It is hinged with rotatable lock pin block 11 in described fixing chute 8；Corresponding described lock pin block 11 is in described cunning
It is provided with dynamic chute and touch bearing pin 12；The described bearing pin 12 that touches is collectively formed in order to scalable with the cooperation of described lock pin block 11
Take turns into line-locked locking mechanism.
Described fixing chute 8 is the concave shape structure of lower surface opening, and the side wall of described fixing chute 8 has use
The short slot being slided with lock pin block.
Described movable sliding 9 is the concave shape structure of upper surface opening；On the side wall of described movable sliding 9, there is use
The short slot being slided with lock pin block.
The back side of described casing is provided with the draw-in groove in order to suitcase and draw-bar box to be assembled into one.
In conjunction with Fig. 3, during use, as long as suitably pull at movable sliding being displaced outwardly, when moving to certain position, touch pin
Axle 12 touches lock pin block 11, so that one end of lock pin block 11 is rotated into movable sliding and fix the gap slot that chute side is opened
Interior, now, push back movable sliding slightly mobile very short distance inwards, the inner side of movable sliding can touch one side of lock pin block,
Limit lock pin block to be rotated further, the lock pin block that simultaneously can not rotate also limit movable sliding and continues rollback, due to the work of extension spring
With movable sliding also will not slide in and out, and which achieves the outer shifting of roller；When scalable wheel will be allowed to be retracted into original position, only
Suitably to pull at movable sliding to be displaced outwardly, touch bearing pin and can touch lock pin block again, make one end of lock pin block sliding from activity
The gap slot that groove is opened with fixing chute side spins out, and now, unclamps movable sliding, and due to the effect of extension spring, activity is sliding
Groove will be retracted in fixing chute, so that roller resets；After scalable wheel pull-out, when tilting to pull draw-bar box, draw
Bar case is just moved with the contact point on ground to outside the dorsal part of draw-bar box, is equivalent to the center of gravity having raised draw-bar box, can avoid pull bar
The case and bag of case dorsal part touch ground.
