Described telescope support is made of outer tube and interior pipe, is provided with described detent mechanism at an end of outer tube, and this mechanism is made up of adjustable block tongue and the draw-in groove that cooperates with described block tongue established on inner pipe; On described adjustable block tongue, be connected with adjusting rod or knob.
The two ends of described hull are circular arc; Be provided with collapsible drip stand in the top of described hull, be provided with hook or link in the outside.
Downside at described hull is provided with support bar; Downside and crawler belt upside at hull are provided with the shackle member that cooperatively interacts.
Described crawler belt wheel comprises crawler belt, roller, rolling wheel support and back shaft, roller of each rotational support of the two ends of rolling wheel support, on roller, be provided with crawler belt, the support of downside crawler belt inboard is provided with microscler belt grooves between two rollers, this elongated slot has a plurality of transverse openings, and each opening is equipped with back shaft; Described crawler belt and roller respectively have two covers and are arranged in parallel.
Be provided with the crawler belt tightening mechanism in the junction of described rolling wheel support and roller.
Telescope support of the present utility model is telescopic folding easily; No matter the wheel of caterpillar belt structure is level walking or stair activity, can not occur jumping and impacting, highly stable, simple in structure, easy to use.
Description of drawings
Fig. 1 is the structural representation of this utility model walking states;
Fig. 2 is the structural representation of this utility model folded state;
Fig. 3 is an example structure sketch map of this utility model retention mechanism.
The specific embodiment
Referring to Fig. 1 and Fig. 2, this utility model comprises the boxlike hull that is made of base plate 2 and sweep frame 1, constitutes telescope support and crawler type wheel 20 by outer tube 9 and interior pipe 19, and the following middle side part of base plate 2 is hinged in the upper end of the outer tube 9 of support.The middle part of the rolling wheel support 13 of wheel 20 is hinged in interior pipe 19 lower ends of support.Be provided with detent mechanism 10 on described telescope support, pipe 19 can not be withdrawn in being used for making after interior pipe 19 stretches out outer tube 9, has only by artificial adjusting and could withdraw.The adjustable side of detent mechanism 10 is connected to below one end of hull by adjusting rod 5, regulates with convenient.Hinged part at the support two ends respectively is provided with retention mechanism 17 and 8, so as when user mode, will to be hinged locate locking, prevent to rotate.
Outer tube 9 and interior pipe 19 can adopt square tube, also can adopt pipe.When adopting pipe, need between inner and outer pipes, be provided with and prevent the structure of rotating, as chute and ledge arrangement.
Described detent mechanism 10 can adopt the structure of door spring lock, is made up of adjustable block tongue and the draw-in groove of establishing on inner pipe that cooperates with described block tongue.Except adopting above-mentioned adjusting rod 5 (its structure is identical with the door lock pull bar control structure of motor vehicle door) to regulate, also can adopt the knob structure of similar common door lock.
The two ends of described hull are circular arc, or four jiaos be circular arc, turn with convenient.Collapsible drip stand 3 can be set in the top of described sweep frame 1.Be provided with hook or link 4 in the outside as binding usefulness.
Downside at described hull is provided with support bar 7 on one side, is used for supporting hull when folded state, makes it keep balance (referring to Fig. 2).Be provided with the shackle member 18 and 6 that cooperatively interacts at the downside of hull and rolling wheel support 13 upsides of crawler belt, be used for that both lock mutually at folded state.
Described crawler belt wheel 20 comprises crawler belt 16 (can adopt balata belt), roller 15, rolling wheel support 13 and back shaft 14, roller 15 of each rotational support of the two ends of rolling wheel support 13, in roller 15 upper supports crawler belt 16 is arranged, on the support of downside crawler belt inboard between two rollers, be provided with microscler belt grooves 12, this elongated slot has a plurality of transverse openings, and each opening is equipped with back shaft 14.Described crawler belt and roller respectively have two covers and are arranged in parallel.Described crawler belt 16 and roller 15 respectively have two covers, and are arranged in parallel.The inboard of roller 15 and crawler belt 16 is provided with intermeshing tooth, groove structure.
Junction at described rolling wheel support 13 and roller 15 is provided with crawler belt tightening mechanism 11, and this mechanism can adopt the structure between bicycle rear axle and the vehicle frame, and its effect is the position of axle on rolling wheel support 13 of regulating roller 15, keeps the rate of tension of crawler belt.
