Description
Technical field
The utility model relates to a kind of draw-bar box, particularly a kind of adjustable case body and ground level draw-bar box.
Background technology
Current, various case and bag generally install universal wheel in bottom, and the shortcoming of installing this universal wheel is: when case and bag complex road condition particularly in the motion of rough road surface time, easy scratch or drench bottom body bag or the travel(l)ing rest of universal wheel.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of adjustable case body and ground level draw-bar box, when case and bag complex road condition particularly in the motion of rough road surface time, scratch can be avoided or drench bottom body bag or the travel(l)ing rest of universal wheel.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of adjustable case body and ground level draw-bar box, draw-bar box comprises casing, be located at the universal wheel of casing lower surface, be located at the pull bar of body side, described universal wheel comprises fixed disk, rolling disc, wheel, wheel is connected with fixed disk by rolling disc, rolling disc can rotate relative to fixed disk, be connected by telescoping mechanism between casing with universal wheel, telescoping mechanism comprises slider bar, chute, chute is located on wall box, slider bar is located in chute, and can slide in chute, slider bar one end is connected with universal wheel fixed disk, universal wheel fixed disk is provided with backstay, backstay can insert the locating hole on rolling disc.
Further, be provided with side wheels in chute, side wheels is fixed in chute by elastomeric element, and chute dual side-edge is provided with draw-in groove, and draw-in groove is provided with clamp, and clamp moves into the flexible of chute restriction elastomeric element.
A kind of adjustable case body that the utility model provides and ground level draw-bar box, by the slider bar in mobile chute, the distance between universal wheel and casing can be regulated, thus the distance raised with universal wheel travel(l)ing rest and ground bottom case and bag, scratch can be avoided or drench bottom body bag or the travel(l)ing rest of universal wheel, through locating hole universal wheel to be turned to by backstay and position, make universal wheel only towards a direction motion, when case and bag particularly move on rough road surface at complex road condition, convenient operation personnel drag draw-bar box.
When sliding panel skids off chute, side wheels is released chute by elastomeric element, then clamp is moved into chute and carry out spacing to elastomeric element, and draw-bar box can be facilitated to top bar.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is A-A sectional schematic diagram in Fig. 1.
Fig. 3 is the use reference view of utility model.
As in figure, casing 1, universal wheel 2, fixed disk 3, rolling disc 4, wheel 5, slider bar 6, chute 7, backstay 8, locating hole 9, side wheels 10, elastomeric element 11, draw-in groove 12, clamp 13.
Detailed description of the invention
As Fig. 1, in Fig. 3, a kind of adjustable case body and ground level draw-bar box comprise casing 1, be located at the universal wheel 2 of casing lower surface, be located at the pull bar of casing 1 side, universal wheel 2 comprises fixed disk 3, rolling disc 4, wheel 5, wheel 5 is connected with fixed disk 5 by rolling disc 4, rolling disc 4 can rotate relative to fixed disk 5, be connected by telescoping mechanism between casing 1 with described universal wheel 2, described telescoping mechanism comprises slider bar 6, chute 7, chute 7 is located on casing 1 sidewall, slider bar 6 is located in chute 7, and can slide in chute 7, as in Fig. 2, side wheels 10 is provided with in chute 7, side wheels 10 is fixed in chute 7 by elastomeric element 11, slider bar 7 one end is connected with universal wheel 2 fixed disk 5, fixed disk 5 is provided with backstay 8, backstay 8 locating hole 9 that can insert on rolling disc 4 realizes positioning universal wheel 2, universal wheel 2 is moved to a direction, chute 7 dual side-edge is provided with draw-in groove 12, draw-in groove 12 is provided with clamp 13, during work, slider bar 6 is skidded off chute 7, side wheels 10 is released chute 7 by elastomeric element 11, again clamp 13 is moved into the retraction that chute 7 limits elastomeric element 11, adjustable case body is realized and ground level draw-bar box is topped bar by side wheels 10.
Structure in this example is only illustrating and explaining for claim, so that mass reading is understood, should not be considered as the restriction for claim, such as the citing of universal wheel direction-control apparatus, do not refer to that the utility model is only limitted to use latch or pole, other direction controlling mode can also be adopted; Motion bar is inserted and exits pin hole; do not refer to that the utility model is only limitted to manually or utilizes case drawbar to operate; can also adopt other modes to operate, the scope that protection domain of the present utility model should be recorded with claim and legal equivalent feature are as the criterion.
