Abstract

The utility model relates to a disk brake setup device of bicycles. A locking hole end of a bow compass is concavely provided with an eccentric hole so that a sleeved section of one end of a locking rod passes through a locking hole and a short screw-shaped section on the end side can be exposed in the eccentric hole. Thus, the adjustment and positioning of the bow compass can be accomplished in the method that the locking hole shifts to a proper position on the sleeved section, a cap nut is locked with the short screw-shaped section so as to force the sleeved section to offset and buckle with the locking hole, and the long screw-shaped section of the other end of the locking rod passes through a front fork or a gripper and is locked by the cap nut. Therefore, the utility model is extremely simple and accurate in adjustment with convenience and practicability.

Description

The Bicycle dished brake stringer

The utility model relates to a kind of Bicycle dished brake, particularly relates to the Bicycle dished brake stringer of the locking position of the simple and easy adjustment clamp of a kind of energy.

See also shown in Figure 1, with the clamp of Regular Bicycle disc brake and the locking of front fork or back hook is example, it mainly is respectively equipped with perforation 101 and screw 201 in back hook 1 (or front fork) and clamp 2 corresponding sections, it is solid with screw 201 spiral shells of clamp 2 to pass perforation 101 backs for a sealed screw rod 3 respectively, making clamp 2 and back hook 1 (or front fork) fixed is one, and these clamp 2 are concaved with a clamping slot 202 in the bottom surface, pass for a brake disc 4, and be respectively equipped with a brake facing 203 in clamping slot 202 both sides, so, need only lock back hook 1 (or front fork) and clamp 2 just can block brake discs 4 by the brake facing 202 that brake drive clamp 2, reach the function of brake, only, though said structure can reach the purpose of clamp 2 location, right, it still has following disappearance and needs to be resolved hurrily when actual assembled:

Because the locking position of these clamp 2 and back hook 1 (or front fork), must make clamping slot 202 remain on brake disc 4 ccontaining places, just can make brake facing 203 block brake disc 4 in the mode of all pressing, therefore, if clamp 2 device is when there is deviation back hook 1 (or front fork) and position, just must be by the quantity of

clamp

2 and 1 pad 301 of back hook, adjust the relative position of clamp 2 and brake disc 4, when this measure must or reduce a slice pad 301 quantity in every increase, repetitiousness dismounting clamp 2, and pad 301 variable thickness are reacted the relative position of clamp and brake disc 4 surely accurately, obviously, adjust the mode of clamp 2 positions with pad 301, quite loaded down with trivial details and inconvenient, and do not have a practicality.

The purpose of this utility model is to provide a kind of energy tube easily and accurately to adjust " the Bicycle dished brake stringer " of clamp position.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of Bicycle dished brake stringer, mainly be respectively equipped with and bore a hole and lockhole in front fork or back hook and clamp corresponding section, locked after passing for locking pole two ends respectively, making clamp and front fork or back hook fixed is one, be characterized in: these clamp, be that line of centers with lockhole is an axis, be concaved with an eccentric orfice in lockhole is distolateral, and the aperture of this eccentric orfice be greater than lockhole; This locking pole, Yu Yiduan has a shrinking section and a short thread segments, and has a long thread segment in other end, and this shrinking section passes the lockhole of clamp, make short thread segments be revealed in eccentric orfice, for with nut locking after, force the shrinking section skew and fix with lockhole, and this long thread segment pass front fork or after behind the hook cooperation nut locked.Be provided with a baffle ring between this locking pole and perforation.

So, these clamp need only utilize lockhole to be moved to the appropriate location in shrinking section, and with nut and short thread segments locking, force shrinking section skew and fix with lockhole, again with locking pole in addition the long thread segment of end pass front fork or back hook, and the cooperation nut is locked, just can finish the adjustment and the location of clamp, so, quite simple and easy and accurate in the adjustment of the present utility model, can effectively promote comfort feature and practicality in the use.

Below by most preferred embodiment and accompanying drawing Bicycle dished brake stringer of the present utility model is elaborated, in the accompanying drawing:

Fig. 1 is the locking scheme drawing of general clamp and back hook;

Fig. 2 is the three-dimensional exploded view of the utility model one preferred embodiment and front fork;

Fig. 3 is the combination scheme drawing of the above-mentioned preferred embodiment of the utility model;

Fig. 4 is the adjustment scheme drawing of the above-mentioned preferred embodiment of the utility model.

For convenience of description, following embodiment, components identical is represented with identical label, shown in Fig. 2,3, this preferred embodiment is provided with two perforation, 11 and two lockholes 21 in front fork 10 (or back hook) and clamp 20 opposite positions equally, and cooperates a locking pole 30 to be locked respectively, and these clamp 20 are concaved with a clamping slot 22 in the bottom surface, pass for a brake disc, and be respectively equipped with a brake facing 23, below be illustrated at feature of the present utility model in clamping slot 22 both sides:

These clamp 20 are that the line of centers with lockhole 21 is an axis, be concaved with an eccentric orfice 24 in lockhole 21 end sides, and this lockhole 21 does not have screw thread, and the aperture of this eccentric orfice 24 are then greater than lockhole 21.

This locking pole 30, Yu Yiduan has 32 sections of a shrinking section 31, short threads, and has a long thread segment 33 in other end, and and the perforation 11 be provided with a baffle ring 34, and this shrinking section 31 passes the lockhole 21 of clamp 20, short thread segments 32 is revealed in the eccentric orfice 24, for a nut 35 locking after, and this long thread segment 33 pass front fork 10 (or back hook) after cooperation one nut 36 locked.

Above-mentioned is the utility model preferred embodiment structure, the explanation of feature and position, as for its assembling, adjust situation, see also Fig. 3, shown in 4, at first, the long thread segment 33 of locking pole 30 is passed the perforation 11 of front fork 10 (or back hook), wear with the lockhole 21 of clamp 20 and the shrinking section 31 of locking pole 30 again, at this moment, need only operate brake crank (figure does not show) makes brake facing 23 press brake disc, just can be before the shrinking section 31 of locking pole 30 by the lockhole 21 of clamp 20, back slippage, be adjusted to the appropriate location, make clamping slot 22 line of centerss of clamp 20 can be corresponding with brake disc 12 after, again nut 35 is inserted in the eccentric orfice 24 of clamp 20, and screw togather with the short thread segments 32 of locking pole 30, so as to forcing the offset skew of shrinking section 31 with eccentric orfice 24, and fix with lockhole 21, make clamp 20 under clamping slot 22 and brake disc 12 cooresponding states, can be fixed with the shrinking section 31 of locking pole 30 be one, at this moment, need only utilize the nut 36 and the long thread segment 32 of locking pole 30 to screw togather, just can lock front fork 10 (or back hook) and locking pole 30, and reach the purpose of location clamp 20.

So the utility model is by above-mentioned structure real following listed advantage of tool and effect:

The utility model can cooperating by the shrinking section 31 of the lockhole 21 of clamp 20 and locking pole 30, any displacement also is adjusted to the appropriate location, it does not only have the restricted problem of spacer thickness, and must repeated disassembled and assembled clamp 20, more can make the clamping slot 22 of clamp accurate and brake disc 12 is involutory, the adjustment and the location of finishing clamp 20, be with, the utility model is quite simple and easy and accurate on adjusting, and can effectively promote comfort feature and practicality in the use.
