Abstract
The utility model relates to a chain pinch device for a speed-changeable bicycle, which is especially suitable for a front speed-changeable bicycle. A general bicycle chain pinch device for a bicycle adopts a complicated four-bar structure, but the kinetic energy does not need to be transversely adjusted under some conditions. The utility model comprises a fixing plate which can be fixed on a rear shaft and a movable plate connected with the fixing plate through pins. A torsion spring is arranged in the chain pinch device for a speed-changeable bicycle, and pressure guide wheels are fixed on the end parts of the movable plate. The utility model has the advantages of simple structure, practicality, and low cost.
Description
The utility model relates to the variable speed bicycle chain stretching device, is specially adapted to only have the pinch device of the chain of preceding variable speed bicycle.
As everyone knows, the multi-change speed bicycle adopts cone pulley structure more, chain pinch device matching used with it is the four-bar linkage structure, and the pinch device of this structure not only has the effect that compresses chain, and the effect that also has lateral adjustments, if but preceding speed change is only arranged, and trailing wheel is the bicycle of monotropic fast structure, does not then need laterally to have bigger regulated quantity for compactor, therefore, adopting existing change-speed box to be applied to the two-stage derailleur becomes unnecessaryly, otherwise can be become very high cost.
The utility model purpose is the obvious complexity of structure in using under specified conditions according to existing change-speed box, the cost height, thus a kind of chain pinch device simple in structure is provided, this device only is applicable to only preceding speed change is arranged and trailing wheel is on the single-stage speed changing structure bicycle.
The utility model purpose realizes being finished by following mode:
The utility model comprises the adapter plate (7) that can be fixed on the rear axle (1), the portable plate (6) that links with adapter plate (7), portable plate (6) links by bearing pin (3) with adapter plate (7), in establish torque spring (4), the end of portable plate is provided with guiding pinch roller (5), and there is a bending (2) the adapter plate inboard.
Advantage of the present utility model is simple in structure, and cost is low, and is not fragile.
Accompanying drawing 1 is the utility model scheme drawing;
Accompanying drawing 2 is that the A-A of accompanying drawing 1 is to cutaway view;
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing:
The utility model is by the adapter plate that can be fixed on rear axle (1) (7), adapter plate can be selected long: 45mm, wide: 20mm, thick: 3mm, about two pitch-row 40mm, adapter plate (7) has been located a bending in (2), purpose is to make wheel flutter (5) and flywheel as far as possible on a plane, portable plate (6) connects by bearing pin (3) with adapter plate (7), in establish torque spring (4), torsion spring pressure is about 1.5kg, the end of portable plate (6) spiral shell select fixed guide pinch roller (5), track adjusting wheel and prior art indifference use this compactor, the length of chain generally with hinge wheel and flywheel outer through be standard increase again 2～3 the joint.The utility model is simple in structure, and cost is low, is suitable for, for ease of maintenaince.
Claims (2)
1, a kind of variable speed bicycle chain pinch device, it is characterized in that including the bar shaped adapter plate (7) that can be fixed on the rear axle, the portable plate (6) that links with adapter plate, portable plate (6) links by bearing pin (3) with adapter plate (7), in establish torque spring (4), the end of portable plate be provided with the guiding pinch roller (5).
2, a kind of variable speed bicycle chain pinch device according to claim 1 is characterized in that there is a bending (2) the adapter plate inboard.
