Abstract
The utility model discloses a controlling mechanism for front wheel steering of a children's tricycle, which comprises a front rotary shaft, a front rotary component coaxially and fixedly connected with the front rotary shaft, a rear rotary shaft and a rear rotary component coaxially and fixedly connected with the rear rotary shaft; a first pull wire and a second pull wire are connected between the front rotary component and the rear rotary component; the first pull wire and the second pull wire are respectively arranged in a tricycle tube; a block is fixedly arranged in a sleeve tube; when rotated to a certain angle, the rear rotary component is butted with the block. The utility model has simple structure, effectively prevents children from stumbling in getting on or off the tricycle, enhances use safety and controls rotary angles.
Description
Technical field
The utility model relates to a kind of control mechanism of child's three-wheel vehicle front-wheel steering.
Background technology
Present child's three-wheel vehicle is generally used control mechanism when control car front-wheel steering, the adult can handle travelling of car behind car.But in the existing control mechanism, outside the backguy in the control mechanism all is exposed to usually, the child is tripped when getting on or off the bus or travel, certain potential safety hazard is arranged.Simultaneously the car front-wheel angle of rotating is uncontrollable, if the rotation significantly of car front-wheel when car advances may generate a panic to the child, and brings difficulty to overtake the time handling car also for the adult.
Summary of the invention
The purpose of this utility model provides a kind of safety in utilization and can reach the controlled control mechanism of rotational angle of effectively preventing to trip when the child from getting on or off the bus, improve, and this control mechanism can be used on the instruments such as child's three-wheel vehicle, bicycle.
The technical solution adopted in the utility model is: the control mechanism of this child's three-wheel vehicle front-wheel steering, comprise preceding turning cylinder, and the preceding tumbler of captiveing joint coaxial, back turning cylinder, and the back tumbler of captiveing joint coaxial with back turning cylinder with preceding turning cylinder, connect first backguy and second backguy between preceding tumbler and the back tumbler, first backguy and second backguy are separately positioned in the car pipe.
Block is fixedly installed in the sleeve pipe, when the back tumbler when forwarding certain angle to and block offset.The axis coinciding of the fixedly axle center of this block and back turning cylinder, and leave the space between block and the back turning cylinder.First backguy and second backguy are cable wire, and cable wire coats one deck polyvinyl chloride leather sheath outward.
In the utility model,, avoid the child when getting on or off the bus or travel, to trip, improved the safety that carriage for children uses because backguy is arranged in the car pipe.At the sleeve pipe internal fixation link stopper is set, make when the back tumbler forwards certain angle to and block offsets, thereby play the problem of control back tumbler rotational angle, because the back tumbler links to each other with preceding tumbler by backguy, thereby also controlled the rotational angle of preceding tumbler, reached the purpose that preceding turning cylinder of control and front vehicle wheel rotate.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 be among Fig. 1 A A to enlarged drawing;
Fig. 3 be among Fig. 1 B-B to cutaway view;
Fig. 4 be among Fig. 1 B-B to the enlarged drawing of rotational angle;
Fig. 5 be among Fig. 1 B-B to the enlarged drawing of another angle of rotation.
The specific embodiment
Extremely shown in Figure 5 as Fig. 1, the control mechanism of this child's three-wheel vehicle front-wheel steering, turning cylinder 1 before comprising, and the preceding tumbler 5 of captiveing joint coaxial, back turning cylinder 2, and the back tumbler 6 of captiveing joint coaxial with back turning cylinder 2 with preceding turning cylinder 1, connect first backguy 7 and second backguy 8 between preceding tumbler 5 and the back tumbler 6, block 10 is fixedly installed in the sleeve pipe 3, when back tumbler 6 when forwarding certain angle to and block 10 offset.
Preceding turning cylinder 1 and front fork arm 9 interlocks, current turning cylinder 1 drives front fork arm 9 when rotating and rotates, thus the rotation of drive car front-wheel.
Back turning cylinder 2 plays the effect of rotation, and the rotation of back turning cylinder 2 does not influence the motion of back wheels of vehicle.
Block 10 also can be enclosed within on the turning cylinder 2 of back, its fixedly axle center and the afterwards axis coinciding of turning cylinder 2, but all leave the space between block 10 and back turning cylinder 2 and the back tumbler 6, make that block 10 can not be subjected to the effect of power when back turning cylinder 2 and back tumbler 6 rotated.
Principle of work of the present utility model is as follows: when back turning cylinder 2 cws or when rotating counterclockwise, with the back back tumbler 6 that is fixed together of turning cylinder 2 also cw or rotate counterclockwise, thereby first backguy 7 that drive links to each other with back tumbler 6 and the stretching and the contraction of second backguy 8, the effect of meeting generation power, the power that produces passes to the preceding tumbler 5 that links to each other with backguy by backguy, also cw or rotate counterclockwise of tumbler 5 before making, drive the rotation of the preceding turning cylinder 1 that is fixed together with preceding tumbler 5, preceding turning cylinder 1 can drive the rotation of vertical tube of front fork 9 again, thus the rotation of control car front-wheel.
When back tumbler 6 forwards certain angle to, offset with the block 10 that is fixedly installed in the sleeve pipe 3, this moment, back tumbler 6 stopped operating, and block 10 plays the effect of control back tumbler 6 rotational angles, and finally reaches the effect of control car front-wheel rotational angle.Periphery at link stopper 10 also can be provided with projection, and this projection plays the reinforcement protective effect of link stopper 10.
