Description

Multifunction bicycle

The utility model relates to a kind of bicycle, particularly multifunction bicycle.

Along with the raising of living standards of the people, the development of tourist industry, the narrow present situation of living conditions in addition, people have proposed numerous requirements to bicycle, and the appearance of folding bicycle is exactly one of them.Current folding frame folding device has bolt type, set pin formula, pawl formula, movable lug formula, button, garden shaft type and spiral, is that 87203785 folding bicycle is exactly like this as number of patent application.What have has installed the tire Floor Pump additional in the seat tube under the bicycle saddle, as number of patent application is that upright beam Floor Pump of 88209760.1 bicycle and number of patent application are that 85205589 the bicycle of making Floor Pump with bicycle frame tube is exactly like this, the former has used the flexible foot-operated mechanism of inflating of a cover, the latter has been installed rigid lever that a cover stretches out backward additional and has been inflated mechanism, complex structure.The bicycle bell of existing bicycle, no matter be single bell cover or two bell cover, the bell cover all is to be screwed on the bell seat with the center threaded fasteners, without instrument, just be easy to back out with hand, so losing phenomenon, the bell cover often takes place, how to guarantee that the bell cover do not lose, having become the problem that vast bicycle user pays close attention to, also is creator's a problem, and number of patent application is that 87204942 anti-theft bicycle bell is exactly an example, this bell has increased by cover locking parts, have only with key and open lock, just can take off the bell lid and unload the bell body, though safety feature height complex structure cost height.Traditional bicycle front fork does not have damping, this jolts when travelling on unmade way is quite serious, especially on the dirt road in vast rural area, travel, number of patent application is that 85204261 damping bicycle is born for addressing this problem, it has structurally changed the form of standard bicycle triangular frame fully, has used a kind of four-bar linkage, this bassinet structure complexity, technology difficulty is big, and load-bearing capacity is not high.

The purpose of this utility model is to provide a kind of vehicle body to fold, and handlebar can load and unload fast, the front fork damping, and bicycle bell is antitheft, and is foot-operated collapsible, can inflate, and establishes the multifunction bicycle of camera support.

Multifunction bicycle described in the utility model (seeing accompanying drawing 1) mainly is made up of handlebar 1, vehicle frame 3, saddle 5, shelf 7, trailing wheel 8, transmission device 10, front-wheel 12, front fork 13, stop mechanism 15, it is characterized in that being equipped with on the handlebar 1 handlebar quick assembling/disassembling mechanism 14 and anti-robbery bell 2, folding safety switch 4 is housed on the vehicle frame 3, camera support 6 and Floor Pump 9, damping is housed in the front fork, rotatable left threading 11 is housed in transmission device 9.Shock-absorbing front fork 13(sees accompanying drawing 2) mainly form by breeches pipe 16, spring abutment pin 17, fork shaft pilot pin 18, spring abutment 20 and spring 21.The front end of the pipe that assembles mutually with handlebar 1 on the breeches pipe 16 is processed with screw thread and male cone (strobilus masculinus), has four equidistant axially elongated slots on the circumference of the conical surface and threaded portion.Adopt this structure can absorb when driving because the increment load that jolts and cause that Uneven road causes makes driving steadily, one side has been protected be hit for a short time influence of load of other parts of bicycle, and the cyclist is felt comfortably cool.Handlebar quick assembling/disassembling mechanism 14(sees accompanying drawing 3) mainly form by jam nut 22, cushion rubber 23, lamp hook 24, bearing 25, be processed with the identical inner conical surface of male cone (strobilus masculinus) on one section tapering and the breeches pipe 16 on the jam nut 22 at the tapped bore rear portion, the cone match of it and breeches pipe 16 ends, tighten jam nut 22 with strength, can make breeches pipe 16 tightly clamp handlebar 1, when unloading handlebar 1, can extract handlebar 1 at an easy rate out as long as unclamp jam nut 22, overcome the shortcoming that traditional interior locking mode makes the pipe chap of handlebar lower end be difficult to extract out.Anti-robbery bell 2(sees accompanying drawing 4) mainly by bell cover 26, center shaft 27, sun gear 28, quadrant gear 29, reed 30, drain pan 31

other end pin hole is made the M8 double off-set spanners, thereby to make it be the locking piece of a safety switch 4, be again a common tool, location safety lock 35 is dimerous by latch and lock body.When mounted, earlier vehicle frame 3 is flattened and align, make eccentric handle 33 its handle vertical eccentric shaft is inserted in the hole of hinges 36 under the state of vehicle frame 3, again behind vehicle frame 3 counter-clockwise half-twists, under the effect of eccentric shaft, vehicle frame 3 closely is close together in the joint, the other end of at this moment eccentric handle 33 forwards safety lock 35 tops, location to, plugs latch, pins with lock, thereby eccentric handle 33 is fixed on the position that makes vehicle frame 3 lockings, safe and reliable.Camera support 6(sees accompanying drawing 8) mainly by saddle pedestal 37, movable lug latch 38, clip 39, lock screw 40, seatpillar 46, photography platform telescopic pipe 47, clamp handle 48, elasticity swivel eye 49, camera mount 50 and video camera fix screw 51 are formed, seatpillar 46 is contained in the standpipe of vehicle frame 3, determine its position by clip 39 with respect to vehicle frame 3 standpipes, photography platform telescopic pipe 47 is equipped with in its inside, its overhanging end is welded with the saddle fixation short tube, saddle is sleeved on the short tube by pedestal 37, be locked on the position with movable lug latch 38, quick release, safe and reliable.Photography platform telescopic pipe 47 is fixed its position with respect to seatpillar 46 by lock screw 40, its overhanging end suit elasticity swivel eye 49, this ring can be around 360 ° of rotations of axis of pipe, to regulate photography direction, camera mount 50 can be around the lateral shaft rotation of swivel eye 49, to regulate the angle of photography, after direction and angle all mix up, rotation lock handle 48 is locked swivel eye 49 and camera mount 50 simultaneously, and video camera is fixed on the camera mount 50 by fix screw 51.When seatpillar 46 is all pulled out suitable length with photography platform telescopic pipe 47, use inflatable umbrella head supporting of video camera fix screw 51 installations at the top and can enjoy the cool with it, be convenient to the traveller and use.Floor Pump 9 designs mainly are made up of hinge 41, adapting pipe 42, air outlet valve 43, leather cup 44, air inlet valve 45 in the interior bottom (seeing accompanying drawing 8) that the vehicle frame saddle is installed standpipe, it is characterized in that the lower surface of air outlet valve 43 designs at Floor Pump 9, air inlet valve 45 is located at the lower end of connection pipe 42, all is made up of steel ball and spring.Adapting pipe 42 upper ends join by hinge 41 and seatpillar 46, and leather cup 44 is equipped with in its lower end, the lower end of the valve seal seat tube of giving vent to anger, and seat tube is exactly the shell of Floor Pump 9.Compact conformation is hidden.When inflating, unload saddle, unclamp the lock bolt 40 of clip 39, hold saddle fixation short tube push-and-pull seatpillar 46 up and down, can realize inflation of tire.Rotation left threading 11(sees accompanying drawing 10) mainly by crank 52, taper pin bolt 53, tension spring 54, half knob pin 55, rotating pedal spindle 56 and foot-operated 57 forms, the shank of crank 52 is made hollow, have 3 pairs of equidistant L shaped grooves on its wall, the both sides and the symmetry of every pair of groove separation crank axis, half knob pin 55
