Technical field
The utility model relates to a kind of bicycle, particularly a kind of bicycle folder.
Background technology
The folder that most bicycles use, it is straight pin to be inserted in the dowel hole lock that considerable part is arranged.For can fast speed assembling, remain with very big gap between the cylinder latch of this folder and the dowel hole, cause the locking of this kind folder after, occur loosening between two fishplate bars that are hinged easily; When serious, this loosening normal use that will directly influence bicycle.Yet, must keep enough big gap again between this cylinder latch and the pin-and-hole, can guarantee that just the cylinder latch inserts smoothly, so the loosening problem of the folding joint of this structure can't be eliminated.
The utility model content
The purpose of this utility model be to provide a kind of simple and reasonable, flexible operation is laborsaving, accurate positioning, cooperate bicycle folder closely, to overcome weak point of the prior art.
By a kind of bicycle folder of this purpose design-calculated, comprise the interior fishplate bar and the boards that are hinged on the jointed shaft, its architectural feature is that folder is provided with horizontal lockout mechanism, this lockout mechanism comprises the eccentric shaft part that is provided with on the jointed shaft, match with this off-centre shaft part be arranged in fastening screw on the fishplate bar; What fastening screw slided is arranged on the bearing, and one end and eccentric shaft part join, and are provided with retracing spring between this end and the bearing, and its other end is pressed against on the latch ramp of boards.
Above-mentioned fastening screw end is provided with adjust bar, and the other end is provided with the circular conical surface that matches with the latch ramp of boards; Be threaded between adjust bar and the fastening screw, the adjust bar top is a taper platform, and the adjust bar top leans on eccentric shaft part; Retracing spring is arranged between adjust bar and the bearing.Bearing is an inverted u-shaped or U font structure, and its dual-side is provided with concentric circle holes, and bearing is fixed on the interior fishplate bar.Eccentric shaft part is arranged on the jointed shaft middle part, fishplate bar middle part in fastening screw and bearing are arranged on.
Above-mentioned jointed shaft two ends are concentric axle head, and the one end is big end, and the other end is a small end, is respectively arranged with big hole and small sircle hole on interior fishplate bar of Pei Heing and the boards therewith, is connected with turning handle on the big end of jointed shaft.The big end of jointed shaft is provided with a counterbore vertically, is disposed with pressure spring in this counterbore from inside to outside and bumps pearl; Counter bore side, corresponding eccentric shaft part are given prominence to or the depression direction offers a cross through hole, and turning handle passes this cross through hole, bumps pearl and is resisted against the turning handle side.Two ends, the turning handle left and right sides are respectively arranged with positioning groove or knock hole, and turning handle one end is provided with the diameter limited step bigger than cross through hole diameter, and its other end is provided with the screw thread that can cooperate with acorn nut.The side that boards is positioned at the big end of jointed shaft is provided with the positioning and guiding chute of turning handle, and this positioning and guiding chute is made up of the U font postive stop baffle that is arranged on the boards.
Above-mentioned turning handle structure also can be like this, and the turning handle side is provided with positioning boss, and corresponding boards is provided with guide chute; Or the turning handle side is provided with guide chute, and corresponding boards is provided with positioning boss.
When turning handle slides into a left side or limit on the right-right-hand limit position in cross through hole, bump pearl and under action of the spring, just cut positioning groove, realize the location; Have only turning handle is applied certain axial force, just can make and bump pearl and withdraw from positioning groove.
When folder was in the lock state, turning handle inserted in the positioning and guiding chute of the U-shaped postive stop baffle composition on the boards, prevented that turning handle from rotating voluntarily because of loosening, plays and guarantee safe effect.
The utility model turning handle drives jointed shaft and rotates, eccentric shaft part on the jointed shaft promotes to move behind the fastening screw gradually, the circular conical surface of fastening screw end is crimped on the latch ramp of boards, the locking of realization folder, the power of promotion fastening screw insertion latch ramp is provided by the eccentric segment of jointed shaft stage casing bending; Adjust bar screws into the degree of depth in the fastening screw tapped bore, the size of adjustable folding device coupling mechanism force by adjusting; Long turning handle and jointed shaft are connected, and be in the time of can making the folder switch, more lightly laborsaving; When turning handle forwards to when withdrawing from lock-out state, the retracing spring resilience drives the fastening screw reach, makes the fastening screw end withdraw from latch ramp, thereby opens folder.
The utility model is simple and reasonable, flexible operation is laborsaving, accurate positioning, cooperation are tight.
