The utility model is connected as a single entity rear bicycle support and lock, the independent production and the installation of driving pin and lock for a short time on the former car ladder have been saved, reduced productive costs, reduced the cyclist and pedaled and drive the fixedly action of car ladder of pin for a short time, save time, laborsaving, strengthened theftproof performance.
Concrete structure of the present utility model is provided by accompanying drawing 1,2.
Fig. 1 is the overall schematic of seat support behind the multifunction bicycle.
Fig. 2 is the structural representation of locking bar enclosure.
Keystone configuration is among the figure: connecting panel 1, quadrant gear 2, transmission gear 3, last locking bar 4a, middle locking bar 4b, following locking bar 4c, lock 5, car ladder 6, curved groove 7, sliding screw 8, back cover lock nose 9, hinge bar 10, locking bar shell 11, pin 12, spring 13, tooth 14, perforation 15, sliding tray 16, retracing spring 17, connecting rod 18, lock housing 19, spring wire 20, lock shell plate 21, connecting bore 22, back axis hole 23.
Below in conjunction with accompanying drawing, the utility model is described in detail.
Seat support behind the utility model multifunction bicycle is made up of connecting panel 1, quadrant gear 2, transmission gear 3, last locking bar 4a, middle locking bar 4b, following locking bar 4c, locking bar shell 11 and lock 5.Right-hand member has half moon connecting panel 1 left end of curved groove 7 to be connected by connecting bore 22 and car bottom girder, upper right side is movably connected with the car ladder 6 that is fixed with quadrant gear 2, the arc length of curved groove is that 1/4th circular arc is long, is level for lifting, falls to vertically with the stroke of controlling the car ladder.Nose 9 is locked by stretching to sliding screw 8 in the curved groove back cover that is connected in car ladder middle part, the back cover purpose of back cover lock nose 9 so as not to the thief from back cover locking bar is disclosed out, the left oblique upper of quadrant gear 2 is equipped with on connecting panel and quadrant gear ingear transmission gear, be close to transmission gear and on connecting panel, be welded with locking bar shell 11, wear a pin 12 on the locking bar shell in the end housing, hang with spring 13 on the pin, locking bar has been colluded in the spring lower end, last locking bar and middle locking bar flexibly connect by hinge bar 10, end, the bottom right sideband tooth 14 of middle locking bar, be installed with the lower end in two perforation 15 on last locking bar top and lean against the other directed spring wire 20 of middle locking bar, the effect of directed spring wire is that end tooth and the transmission gear with middle locking bar meshes all the time, be installed with the connecting rod 18 that is overlapping retracing spring 17 in the sliding tray 16 of middle locking bar bottom, the other end of connecting rod 18 is connected in the upper end that the lower surface is the following locking bar 4c on inclined-plane, the top of locking bar shell is with lock housing 19, and lock 5 is housed in the lock housing 19, and lock is with existing phase-locked same.Connecting panel is connected on the car rear axle by back axis hole 23, and lock shell plate is connected on the rear deck seat by connecting bore, and locking bar shell top links to each other with rear bicycle, plays the effect of rear bicycle support.
During use, slide along curved groove with pedal car ladder, locking bar moved downward under the locking bar connecting rod reached in the middle of the end tooth of the locking bar in the middle of the quadrant gear at car ladder top will drive by transmission gear at this moment made, when the lock nose on the car ladder is run into the end inclined-plane of following locking bar, the lock nose moves along the end inclined-plane and causes down locking bar upwards, and connecting rod is along sliding on the sliding tray, the lock nose move to beveled top end and aim under during locking bar, the following locking bar spring that will be reset pushes in the back cover lock nose, locks car at once.During driving, key makes locking bar break away from lock, and the spring that catches on locking bar will be gone up on the locking bar by restoring force and draw, from and drive locking bar upward movement separating lock nose, lock is promptly opened.With pin the car ladder is pedaled back, just can be by bike.
