Abstract
The utility model relates to a chain regulating device of motorcycle, which comprises a sliding block, which is positioned in a bottom fork and is sleeved on a rear-wheel spindle; and a keep plate, which is arranged at the end of the bottom fork; an adjusting bolt is connected between the sliding block and the keep plate, and the head of the adjusting bolt is positioned on the keep plate; the threaded rod part of the adjusting bolt is screwed inside the thread hole of the sliding block. When in operation, the slipped screw phenomenon is not easy to happen in the chain regulating device, and a normal and reliable use of the regulating device can be ensured; simultaneously due to the head of the adjusting bolt is arranged inside the counter bore of the screw through hole of the keep plate without being exposed outside the keep plate, therefore, the entire appearance of the motorcycle is not affected.
Description
Technical field
The utility model relates to a kind of device that motorcycle chain is regulated that is used for.
Technical background
The device that is used for the motorcycle chain adjusting at present is by being positioned at chain stay and being sleeved on the slide block on the hind axle, the pressing plate that dress is pressed in the chain stay tail end, and the screw rod and the setting nut that are connected between slide block and the pressing plate are formed, screw rod is fixed on the slide block and passes pressing plate, and setting nut is spun on the screw rod and with pressing plate and is pressed on the motorcycle bottom fork tail end.When regulating operation, the rotation setting nut is with pulling screw rod, slide block, thereby the pulling motorcycle rear axle makes it produce displacement, realizes the adjusting of chain degree of tightness.There are two drawbacks in the adjusting device for chains of this kind structure: the one, because mate is very short between setting nut and screw rod, in regulating operating process, be easy to generate stripped thread, and influence the normal use of control apparatus; The 2nd, this kind structure is given prominence at the chain stay tail end because screw rod passes from pressing plate, hinders the attractive in appearance of motor bike monnolithic case.
The utility model content
Technical problem to be solved in the utility model provides a kind of motorcycle chain regulating mechanism, makes adjustment of chain convenient reliable, helps the attractive in appearance of motor bike monnolithic case simultaneously.
Motorcycle chain regulating mechanism described in the utility model, comprise that the slide block and the dress that are positioned at chain stay and are sleeved on the hind axle are pressed in the pressing plate of chain stay tail end, between slide block and pressing plate, be connected with the adjusting bolt, and regulate bolt head and be positioned on the pressing plate, the threaded shank portion of regulating bolt is spun in the tapped bore of slide block.
Be used to install the mounting hole of regulating bolt on the pressing plate and be provided with counterbore, regulate bolt head and be arranged in this counterbore.
When regulating chain, rotate and regulate bolt, then slide block drives motorcycle rear axle and moves the realization adjustment of chain.
The utility model is owing to replaced the screw rod and the nut of former adjusting device for chains with bolt, and nut directly meshes with slide block, and its mate is longer, so be not prone to the stripped thread phenomenon, can guarantee the use of control apparatus normal reliable; Because bolt head is arranged in the counterbore of follower bolt via hole, do not expose outside the pressing plate, simultaneously so do not influence the overall appearance of motor bike.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the scheme drawing of a kind of concrete structure of motorcycle chain regulating mechanism described in the utility model, and motorcycle bottom fork is partly represented in two-dot chain line among the figure.
The specific embodiment
As shown in Figure 1, this motorcycle chain regulating mechanism comprises and is positioned at chain stay and is sleeved on slide block 1 on the hind axle and pressing plate 6 that dress is pressed in the chain stay tail end, offer a through hole 2 and a tapped bore 3 on the slide block 1, can be sleeved on the motorcycle rear axle by these through hole 2 slide blocks 1, pressing plate 6 is installed on the motorcycle bottom fork tail end end face, the bolt that offers the band counterbore on it is installed through hole 5, hexagonal is regulated bolt 4 in slide block 1 and 6 of pressing plates are connected with, and regulate bolt 4 heads and be arranged in this counterbore, the threaded shank portion of regulating bolt 4 is spun in the tapped bore 3 of slide block 1, owing to regulate the effect of bolt 4, make pressing plate 1 be pressed on motorcycle bottom fork tail end end face.
When regulating chain, rotate and regulate bolt 4, can not move along its axis,, drive motorcycle rear axle then and move, thereby realize adjustment of chain so slide block 1 is moved along regulating bolt 4 axis directions owing to regulate the restriction of bolt 4 compression plates 1.
Claims (2)
1, a kind of motorcycle chain regulating mechanism, comprise that the slide block (1) and the dress that are positioned at chain stay and are sleeved on the hind axle are pressed in the pressing plate (6) of chain stay tail end, it is characterized in that: between slide block and pressing plate, be connected with and regulate bolt (4), and regulate bolt head and be positioned on the pressing plate, the threaded shank portion of regulating bolt is spun in the tapped bore (3) of slide block.
2, adjusting device for chains according to claim 1 is characterized in that: be used for installing the mounting hole (5) of regulating bolt (4) on the pressing plate (6) and be provided with counterbore, regulate bolt head and be arranged in this counterbore.
