Abstract
The utility model relates to an improved bicycle braking device which comprises a brake seat, a tough block, a lantern ring seat and a fastener. A beam sphere which is sheathed in a ring-shaped lantern ring of the lantern ring seat is utilized. After the beam sphere penetrates through a rear supporting rod of the tough block in a forcing-combination hole of the beam sphere and is locked by a bolt of the other end of the lantern ring, the beam sphere is abutted by the frame edge of the top arc of a pressing block by following the locking displacement of the lantern ring. Simultaneously, the beam sphere rotates in the concave arc ring wall of the inner side of the lantern ring, so the offset of an angle of the tough block is quickly and conveniently adjusted.
Description
The utility model relates to a kind of drg of bicycle, especially a kind of improvement that engages the drg of bicycle quick wheel rim with braking element.
Referring to Fig. 5～6: public bicycle brake structure is by cable wire 1 in the application of force pull-up of Brake lever, then descend cable wire 11 to mention and traction braking seat 12 simultaneously thereupon, making it is that axle center and ecto-entad spinning make tough 14 and compressed wheel frame lateral margin 15 with lower supporting hole 13 places, thereby reaches the purpose of brake; One pad 17 of cutting sth. askew of equal thickness not is set in the Brake Block 12 of bicycle brake structure and tough 14 the assembly, adjusts tough 14 angle with this.When tough 14 do up and down or about angle displacement the time, need this pad 17 of cutting sth. askew of rotation to suitable position liner; In fact, whether proper for this being affectedly bashful of pad 17 angle of rotations of cutting sth. askew when when the actual angular deflection of doing tough 14 is adjusted, real difficult work is operated rapidly and effectively and is adjusted.
The purpose of this utility model provides a kind of improved bicycle brake device, it runs through in the hole that is plugged on bundled ball body by tough back stay, but and this bundled ball body also just can be ccontaining and turn in the concave arc ring wall of cover ring seat and unlikely coming off is able to do rapidly and easily angular deflection thereby reach tough.
Second purpose of the present utility model provides a kind of improved bicycle brake device, and it utilizes a briquetting to compel to support the back stay of solid tough of bundled ball body bundle, and reaches tough firm fixation ground pressure-bearing brake.
The utility model is achieved in that a kind of improved bicycle brake device, comprises Brake Block, tough, cover ring seat, fastener, and an end of Brake Block 2 is placed on the bicycle front fork frame by axle bed 21, and the stage casing is provided with elongated hole 22; Tough 4 back is provided with a shaft-like after poppet 41; The middle part of briquetting 7 is provided with through hole 71, establishes caulking groove 72 and top arc architrave 73 at the scalene cone place, hat top of briquetting, and briquetting shade end in addition is provided with sleeve column 74; The middle part of bundled ball body 5 is provided with hole 51, at the side face of hole notch 52 is set; One side of cover ring seat 6 is the cast collar 61, and this cast collar inboard is the ring wall 62 of concave arc shape, and another side of cover ring seat is a double-screw bolt 63; Bundled ball body 5 is sleeved in the collar ring wall 62, and tough back stay 41 inserts in the hole 51 of bundled ball body, and bolt 63 passes the through hole 71 and clamp nut 8 and pad 9 screws thread fit of briquetting.The outside of bundled ball body 5 slightly is spherical shape, and its outer wheels profile cooperates with cast collar ring wall 62 curvature.Tough back stay 41 cooperates with the hole 51 of bundled ball body.
The utility model can be arranged in behind the suitable angle position locking nut again with tough, has simplified control step, and is simple in structure, accurate, and can provide a kind of rapider, tough easily angular adjustment brake structure.The pressure-bearing brake securely of car spheroid difficult drop-off, toughness.

Now further narrate structure of the present utility model in conjunction with the accompanying drawings.
Referring to Fig. 1～4: the utility model comprises Brake Block 2, tough 4, bundled ball body 5, cover ring seat 6, briquetting 7 and coupling nut 8, pad 9.Wherein the hypomere of Brake Block 2 is provided with axle bed 21, can be for being placed on bicycle front fork frame 18, and the stage casing is provided with an elongated hole 22, decides but voltage supply piece 7 supports; Tough 4 back is provided with a shaft-like after poppet 41; The outside of bundled ball body 5 slightly is spherical shape, and its central authorities are provided with a hole 51, establishes a notch 22 at the side face of hole 51; One side of cover ring seat 6 is the collar 61 of cast, and the ring wall 62 of concave arc shape is set in the inboard of the collar 61, so that fit bundled ball body 5, another side of cover ring seat 6 is a double-screw bolt 63; The profile of briquetting 7 slightly is the cap shape, the middle part of briquetting connects the through hole 71 that can run through insertion for double-screw bolt 63 is set, briquetting cap shape top is scalene cone and has a caulking groove 72 just can ccontainingly support the top arc architrave 73 of deciding the collar 61 and replacing bundled ball body 51 local surfaces, and the shade of briquetting 7 end in addition is provided with a sleeve column 74.During assembling, make tough 4 back stay 41 plant going into to be arranged in the hole 51 of the ccontaining bundled ball body 5 of the inner ring wall of the collar 61 62, and the top arc architrave 73 of compression block 7 is replaced with the sealed displacement of cover ring seat 61 by bundled ball body 5 when lock nut 8, makes bundled ball body 5 be compeled to close tough back stay 41 of locking.This bundled ball body can make tough angular deflection be able to rapidly in the 62 inboard turns of collar ring wall, adjusts easily.
The utility model is to adopting the pad of cutting sth. askew movably to rotate the improvement of adjusting tough angular deflection shown in Fig. 5 C, according to the latter, need to support behind a side of tough back stay with Allen wrench earlier to fix the solid nut of other side chain with another spanner again, wherein need adjust simultaneously the position of the pad of cutting sth. askew again, the adjustment process inconvenience.The utility model only need be used hand-held fixed tough extremely suitable angle, gets final product in other side lock nut again.
