Abstract
The utility model relates to a bicycle which can be changed into a unicycle, which comprises a bicycle tripod, handlebars, a seat transmission device, a front wheel and a rear wheel. A front fork of the front wheel is structurally separated from the tripod and the handlebars, a separation insert is arranged between a tripod main tube and the front fork, a braking bolt is arranged on the separation insert, and the braking bolt contacts with a braking link. The bicycle is characterized in that a pedal crank mounted on a main shaft of the bicycle front wheel is connected with the main shaft of the bicycle front wheel through a trapezoidal pin, and is engaged and fixed with a positioning concave position on the trapezoidal pin through a positioning convex position on an inner hexangular screw. In the utility model, the handlebars can be separated from the bicycle body, and after the separation the bicycle is changed into a unicycle for reaction and exercise and simultaneously is burglar proof. After the pedal crank is connected with the main shaft of the bicycle front wheel through one trapezoidal pin, detachment or installation thereof can be quite convenient and speedy, thereby bringing convenience in usage. Further, the structure can be widely applied to installation of pedal cranks of various bicycles.
Description
Technical field
The utility model relates to technical field of bicycles, specifically a kind of bicycle of variable wheelbarrow.
Background technology
Existing bicycle function ratio is more single.The leading separation type anti-theft bicycle that the inventor formerly invents, its tap is separable with front fork, and except the anti-theft feature with bicycle, the wheelbarrow that also can be used as a kind of amusement and exercise usefulness uses.But the stretcher of installing on the axis of bicycle front-wheel (wheelbarrow) turns still with traditional method and installs, and when using as bicycle, need are under this stretcher plag, and all cumbersome time-consuming when taking off or loading onto.
Summary of the invention
The purpose of this utility model provides a kind of bicycle that both can be used as, and can be used as again that wheelbarrow uses, and the stretcher plag down or the bicycle of variable wheelbarrow easy for installation.
The technical solution of the utility model is: comprise bicycle tripod, tap, seat driving device and front and back wheel, the front fork of front-wheel and spider and tap are separate type, between spider house steward and front fork, the plug-in unit of separation is arranged, separate plug-in unit and be provided with braking bolt, braking bolt contacts with brake connecting rod, it is characterized in that the pedal of installing on the bicycle front-wheel main shaft turns by a trapezoidal pin is connected with bicycle front-wheel main shaft, and fixing by the recessed back that cooperates, the location on the protruding and trapezoidal pin in the location on the socket head cap screw.
The bicycle of variable wheelbarrow of the present utility model, tap can separate with car body, become the wheelbarrow of a kind of amusement and exercise usefulness after the separation, also having played simultaneously theft-proof effect (can separate handle-bar and throw off from the spider house steward, front-wheel after the disengagement can be taken away, and has reached theft-proof completely purpose).Pedal turns by a trapezoidal pin with after bicycle front-wheel main shaft is connected, make take off or load onto all easily quick, more convenient to use.And the pedal that this structure can be widely used in various bicycles turns installation.
In addition, bicycle thing frame of the present utility model is movable, and front fork is provided with the thing framework, is fixed by set pin in the bolster embolus frame support pipe of thing frame.Bicycle thing frame also can take off or load onto at any time, can easily the thing frame be carried and going home, with to have the thing frame to compare more convenient.

Fig. 1 is bicycle front fork of the present utility model and front-wheel local structure scheme drawing.
The structural representation that Fig. 2 turns for pedal of the present utility model.
Fig. 3 is the trapezoidal latch structure scheme drawing during pedal of the present utility model turns.
Among the figure, 1-(with leading bonded assembly) bicycle tripod house steward, 2-separation plug-in unit, 3-set pin, 4-front fork, 5-front-wheel, 6-brake support, 7-brake rubber block, 8,9,10-brake connecting rod, 11-braking bolt, 12-brake cable, 13-thing framework, 14-set pin, 15-support tube, 16-front-wheel axis, 17-trapezoidal pin hole, 18-pedal turns, 19-trapezoidal pin, 20-location is recessed, 21-socket head cap screw, and 22-location is protruding.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.But be not limited to shown in the accompanying drawing.
Embodiment: as shown in Figure 1, leading separation type anti-theft bicycle of the present utility model comprises tap, spider, seat, driving device and the front and back wheel etc. of existing bicycle.The front fork of front-wheel and spider and tap are separate type, between spider house steward 1 and front fork 4, the plug-in unit of separation 2 is arranged, separate on the plug-in unit braking bolt 11 is housed, brake cable 12 also is connected in separates on the plug-in unit, separating the plug-in unit bottom is the inserted link that can insert in the front fork tube, and by set pin fix (otherwise, unclamp locating dowel pin and can take out the separation plug-in unit, make the tap separate with front fork); Braking bolt contacts with brake connecting rod 10,9,8, and the pulling brake cable makes braking bolt depress brake connecting rod and reaches the purpose of braking.Bicycle thing frame is movable, and front fork is provided with thing framework 13, and is fixing by set pin 14 in the bolster embolus frame support pipe 15 of thing frame, can take off easily or load onto.Other of bicycle is partly basic identical with existing bicycle.
The pedal of installing on the front-wheel main shaft 16 of bicycle turns 18 and is connected by the trapezoidal pin holes 17 of a trapezoidal pin 19 with bicycle front-wheel main shaft, and by the location protruding 22 on the socket head cap screw without a head with fix after location recessed 20 on the trapezoidal pin cooperates.When taking off, after with a simple hexagonal spanner socket head cap screw being unscrewed, take out trapezoidal pin, can take off pedal and turn.
