Description
Technical field
The utility model relates to a kind of bicycle saddle cushion anchor fitting, especially refer to a kind of being inserted in the bicycle rack, provide the contact application force by screwing togather piece, can make that the bicycle saddle cushion body of rod and bicycle rack are firm to be combined, and can keep the bicycle rack surfacing, reduce the bicycle saddle cushion anchor fitting of windage.
Background technology
The combination of Regular Bicycle seat cushion and vehicle frame is in seat cushion bottom inserted link to be set mostly, be inserted to inserted link in vehicle frame after, lock in the lump by the vehicle frame outside by bolt again, only the existing shortcoming of this kind form is as follows:
One, windage is big, with the compete for speed sports bicycle of usefulness of match, necessarily requires its car body to have perfect stream line pattern, and minimum so that windage is reduced to, the locking component that exposes can increase windage.
Two, locking force is not good, causes easily to get loose, and increases bolt quantity and can make that then weight increases the weight of if improve locking force, and the sports bicycle of usefulness of competing for speed is unfavorable for competing.
Three, during the packing of bolt single-point, cause vehicle frame or inserted link to wreck easily.
Four, cause the vehicle frame surface structure complicated.
Five, destroy the car body cosmetic look.
Six, cause the personnel of driving to touch easily or stumbled by being colluded, cause human injury or other danger.
Based on above-mentioned shortcoming, this case applicant proposes a patent application case " bicycle saddle cushion is loop bar fixedly " (with case before calling patent in the following text) on April 12nd, 2007, and get permission the novel patent of TaiWan, China on November 21st, 2007, notification number M322356, the bicycle saddle cushion that case is proposed before this patent is loop bar fixedly, it comprises that a loop bar, a bolt, screw togather a piece and a slide block, and towards the inner activity space that forms of loop bar, this activity space has a bearing of trend in the loop bar bottom; This bolt is to be arranged in the loop bar towards loop bar inside by the loop bar top, and the axis parallel of nut is in the bearing of trend of activity space; This screws togather piece is to be arranged in the activity space of loop bar, and screws togather mutually with bolt, and this screws togather piece and has an inclined-plane; This slide block has a passage and can wear for bolt, and this slide block is to be arranged in the activity space of loop bar, and between the madial wall that screws togather piece and loop bar, and this slide block has an inclined-plane; Loop bar is sheathed on the bicycle rack, and this screws togather piece and slide block is to be positioned at bicycle rack, when spiral shell moves bolt, can make this screw togather piece and move and promote the madial wall that this slide block is resisted against this loop bar and vehicle frame in this activity space.
Because the loop bar lower part that case is proposed before this patent is a hollow tubular, in order to this loop bar is sheathed on outside the bicycle rack, and bolt, screw togather piece and slide block is positioned at bicycle rack, in other words, bicycle rack is to be located in loop bar and this bolt, screw togather piece, between the slide block, therefore, this bicycle rack must possess the less top of an external diameter, to provide after loop bar puts, can keep a smooth outward appearance, yet because due to the production tolerances such as the caliber of bicycle rack and loop bar and baking vanish, normal generation loop bar and bicycle rack be the stack-mounted situation smoothly, if the bicycle rack external diameter is excessive, then can cause bicycle rack to be arranged in the loop bar, and when bicycle rack and loop bar mismatch, also can't obtain smooth outward appearance, except aesthetic problem, irregular car pipe also can cause windage to improve, smooth and easy when influence drives.
