A kind of bicycle mudguard structure-improved

The utility model provides a kind of bicycle mudguard structure-improved, especially a kind of such bicycle mudguard structure-improved, comprising: an end of tightening device is fixedly arranged on the mudwing, this is tightened device and directly vertical tube is produced and tighten by this, reach its purpose of assembling fast, tighten device directly by the adjustment head of tightening the broken groove rotation adjusting lever on the seat, when being rotated, adjusting lever drives its axostylus axostyle scrolling fastening straps, and fastening straps is tightened fully, latch between mat adjustment head and the broken groove is nibbled the whole state of tightening that locks again, has the tightening structure of adjusting function and reach.

People more and more pay attention to quality of the life at present, along with people's leisure time increases many, therefore, utilize the existing trend that increases rapidly of the number of being engaged in leisure, tourism and motion these holidaies, the expression compatriots begin to pay attention to loosening amusement and travel, the healthy outdoor exercises of emphasis of pressure, and the interaction contact of promoting whole family's emotional affection, this leisure form of changing along with holiday has changed original life pointer widely, allows more people have more time to go to treasure and think deeply health of oneself and at one's side all.

Be engaged in stress-relieving activity to the open air, experience the happy of the Nature, optimum also to reach the healthy instrument of motion promptly be bicycle, can drive bicycle and move about unhurriedly mountain forest yes quite satisfied, in leisure, can move again, and be that the modern is only the most suitable.Therefore, the daily on holiday people that as seen move with bicycle, the wherein improvement that progresses greatly of each position structure of bicycle, even DIY is the stack-mounted product voluntarily, luxuriant is trend in the bicycle market, thus at the structure of bicycle or product improvement to progressing greatly most in the hope of perfect.

The assembling mode of known bicycle mudguard is inconvenience quite, please cooperate to consult shown in the annex by the patent of Taiwan patent announcement No. 379691 " bicycle mudguard structural improvement ", and the major technique of this known patent is characterized as:

Mudwing 20, one end extend a C word shape collar 21, and collar 21 1 ends are provided with a button hook 211, and the other end is provided with pivot knot seat 212, and pivot knot seat 212 is provided with a pivot-juction hole 213;

Button knot body 30 is circular-arc, and front end both sides up and down provides a perforation 31, and a square clasp 32 is tied in nearly middle section both sides pivot up and down, and back segment is provided with a press section 33;

C word shape collar 21 by said structure mudwing 20 can cooperate suitable lining A, a B to be sleeved on the suitable height and position of seat cushion vertical tube 40, button knot body 30 front end sleeves place the pivot of C word shape collar 21 to tie pivot knot on the seat 212, cooperate with the hook 211 of C word shape collar 21 by button knot body 30 in addition, can make C word shape collar 21 firm bundles tie on seat cushion vertical tube 40.

Though it is quick that this known patent can reach more known mode with the hand tool dismounting, but it still has defective, only can be suitable for the seat cushion vertical tube of single size, because C word shape collar 21 directly is of a size of fixing with the circular arc of button knot body 30, it is quite limited to meet the solid vertical tube 40 of size cover, so the bicycle more than two is arranged in the user family, just vertical tube 40 sizes are variant, the user must buy the collar 21 of different size, and select the collar of size conforms also quite to bother for consumers, because the bicycle of how tame label is arranged, kind is distinguished again mountain-climbing car or road sport car or the like different bicycle, and individual difference is quite big on vertical tube 40 sizes.Therefore, the structure that mudwing is installed is except wanting fast speed, and the more important thing is does not need stoning whether size conforms to vertical tube to collar, just can reach the practical product of easy operation and broad applicability.

And another patent characteristic of this known patent is: mudwing 20 and 21 of C word shape collars can be divided into two independent members, and mudwing 20 1 ends are provided with a circular arc projection 22, C word shape collar 21 extends a scalariform circular arc seat 214 in the opposite end of opening in addition, fit by the ratchet-like 215 on ratchet-like on the circular arc projection 22 222 and the scalariform circular arc seat 214, form gratifying adjustment mudwing 20 to required angle.

Though please known patent explain the additional function that it has angle adjustable, but must cooperate a nut to fix by a screw forming still of its angular adjustment structure as can be seen by the Fig. 6 in this annex, so probably will unscrew screw a little in the angle change process could rotate, again screw is locked afterwards, so still quite inconvenience in operation, do not have the known configurations that still how progressive can be sayed, so still have necessity of improving its ease of Use.

The production design person that the applicant behaves and is engaged in bicycle structure for many years, because the neither function that has fast assembling-disassembling and must not use the assembly locking of mudwing fixed sturcture on the market, and the applicant and at present manufacturer's the trend and the defective of trend and above-mentioned known mudwing fixed sturcture, and then design the quite easy mudwing anchor fitting of a kind of operation, to improve above-mentioned all defect.

The purpose of this utility model provides a kind of mudwing structure-improved, wherein tighten device promptly directly by the adjustment head of tightening the broken groove rotation adjusting lever on the seat, when being rotated, adjusting lever drives its axostylus axostyle scrolling fastening straps, and fastening straps is tightened fully, latch between mat adjustment head and the broken groove is nibbled the whole state of tightening that locks again, has the tightening structure of adjusting function and reach.
