Therefore, the utlity model has the characteristics that centering rate height, easy disassembly, stability are strong, safe and reliable, be convenient to vehicle-mounted and open-air use.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the side-looking structural representation of Fig. 1;
Fig. 3 is the plan structure scheme drawing of Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model being further described, is not the restriction to its protection domain:
A kind of oscillating rod type wheel attaching/detaching apparatus: as shown in figures 1 and 3, two side stands 7 are fixed on the two ends of crossbeam 9 symmetrically, two side stands 7 respectively with crossbeam 9 vertical mutually " U " type shape framework that is on horizontal surface, on crossbeam 9, be equipped with and roller 8 be housed respectively below the two ends of 1, two side stand 7 of handrail.For sake of convenience, suppose that the open end of " U " type shape framework is a front end, the end that handrail 1 is housed is the rear end.Two reductors 6 are installed in respectively above the end (rear end) of two side stands 7, are respectively equipped with short pin shaft 12 on the other end (front end) end face of two side stands 7, and additional pull bar 11 is stuck on two short pin shafts 12 versatilely.
As shown in Figure 2, two fork axles 10 are installed in the top of two side stands 7 respectively abreast, one end (rear end) of two fork axles 10 connects with the mouth of each self-corresponding reductor 6 respectively, the other end of two fork axles 10 is installed in respectively in each self-corresponding bearing seat 13, and two bearing seats 13 are separately fixed at the other end (front end) of cooresponding two side stands 7; Fork 4 is equipped with at two of each fork axle 10 respectively regularly, and the upper end of two forks 4 on each fork axle 10 is equipped with a rotary rollers 3 respectively.
In this specific embodiment: two reductors 6 are Worm and worm-wheel gearing; The mouth of reductor 6 is connected with each self-corresponding fork axle 10 respectively, and the input end 5 of reductor 6 adopts manually; Wheel shield 2 is equipped with at the two ends of rotary rollers 3 respectively; Two homonymy of additional pull bar 11 is provided with open circles, and the distance of center circle of two open circles is with the distance of shaft centers of two short pin shafts 12, and additional pull bar 11 is according on the mobilizable card of working condition or take off.
A kind of oscillating rod type wheel attaching/detaching apparatus: the input end 5 of reductor 6 adopts drive of motor.All the other are with embodiment 1.
The U of this specific embodiment " the type framework is the freely supported structure of roller 8 supporting, stress condition is greatly improved, and realizes miniaturization and lightweight easily, is convenient to vehicle-mounted and open-air use, especially is convenient to side stand 7 and pitches the tire bottom; Two rotary rollers 3 make wheel rotate around the central axis of tire in the time of can realizing mounting of tyre, and then realize the centering of wheel rim screw; U " handrail installed on the type framework, can this device be advanced and fall back; The additional pull bar 11 that is provided with can increase the rigidity of U type framework horizontal surface.
