The utility model content

Technical problem to be solved in the utility model is to provide a kind of motorcycle chain regulating control, to guarantee the conformability of two chain adjuster body amount of movements.

The technical solution of the utility model is as follows: a kind of motorcycle chain regulating control, on the chain adjuster body, have the axis hole that connects its left and right side, its key is: the side of described chain adjuster body is provided with two groups of scale marks, these two groups of scale marks are positioned on the sustained height, and separation is in the forward and backward both sides of axis hole.

Adopt above technical scheme, a back vent left side, be provided with scale mark on two chain adjuster bodies in right the person in charge, and the bar hole that the part of scale mark sees through on the back vent person in charge can reveal, nut on the rotating link chain regulating control double-screw bolt like this, when double-screw bolt drive chain adjuster body moves forward and backward in back vent is responsible for, scale mark can change through the scale value that bar hole reveals, can accurately express what of chain adjuster body amount of movement with this, thereby when regulating the chain tension degree, can guarantee that two chain adjuster body amount of movements are identical, prevented that effectively the driven sprocket on trailing wheel and the hind axle from taking place crooked, eliminated the disadvantage of bringing because of crooked, when ensureing trailing wheel and chain service life, guaranteed the safety that car load travels.

In order to reflect what of chain adjuster body amount of movement more exactly, above-mentioned scale mark is made up of the lines that are parallel to each other, and each lines is vertical distribution on the side of chain adjuster body, and on the same group in the scale mark distance between the two adjacent lines bars equal.

For the ease of moulding, the lines of above-mentioned formation scale mark are for protruding the rib of chain adjuster body side; Perhaps, the lines that constitute scale mark sink into the shallow slot of chain adjuster body side in being.

Beneficial effect: the utlity model has be skillfully constructed, simple in structure, implement characteristics such as easy, it is responsible for back vent by scale mark and goes up cooperating of bar hole, can how much revealing with chain adjuster body amount of movement, the amount of movement of two chain adjuster bodies is identical when regulating the chain tension degree with assurance, thereby it is crooked to have prevented that effectively trailing wheel from taking place, alleviate the wearing and tearing of trailing wheel, ensured the service life of tire; Simultaneously, deflection can not take place in the driven sprocket on the hind axle yet, has eliminated like this that stress is concentrated and the disadvantage that causes the chain fracture.In addition, the driver behavior of rider is unaffected, and the safety that car load travels is secure.
