Description

A kind of bicycle tilting prevention device
Technical field
The utility model relates to technical field of bicycles, particularly a kind of bicycle tilting prevention device.
Background technology
Existing bicycle generally all has and prevents the auxiliary wheel fallen down, and auxiliary wheel is rotatably connected on the equalizer bar lower end, and the equalizer bar upper end is fixedly connected on the vehicle frame of bicycle rear portion by a locking plate that has two dops.The locking plate of this structure can only single ground captive joint equalizer bar, and connection mode is single, and equalizer bar can not be turned up.After the user learned by bike, equalizer bar can not be packed up, and so usually brings inconvenience to the user, and particularly when turning round, auxiliary wheel often contacts to earth, and brought unnecessary trouble for the user who has learned by bike.
Summary of the invention
The technical problems to be solved in the utility model is that a kind of bicycle tilting prevention device that makes things convenient for equalizer bar to turn up is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of bicycle tilting prevention device, comprise mounting rod, wheel seat and the roller that is installed on the wheel seat, it is characterized in that: also comprise connecting rod, upper fold rod, middle pole and following pole, the lower end of mounting rod connecting rod one end that is rotationally connected, the connecting rod other end wheel seat upper end that is rotationally connected; The lower end of upper fold rod is provided with U type bayonet socket, and the epimere of middle pole is provided with strip hole, the be rotationally connected middle part of mounting rod, the upper end of upper fold rod, pole upper end during the upper fold rod middle part connects by rotating shaft, the strip hole interpolation patches pin, and the termination clamping U type bayonet socket of latch is connected with spring between latch and the rotating shaft; In the connecting rod middle part that is rotationally connected, the middle part of pole, the lower end of middle pole pole one end that is rotationally connected down, the following pole other end wheel seat lower end that is rotationally connected.
As the further improvement of this city utility model, mounting rod is provided with 3 mounting holes.
The wall suitable for reading of U type bayonet socket is longer than the end opening wall of U type bayonet socket, makes things convenient for the latch two ends to carry out clamping.
Mounting rod is provided with a plurality of assembly openings, and mounting rod is installed in the rotating shaft end of bicycle rear by assembly opening, and a plurality of assembly openings can conveniently be installed in the utility model on the bicycle of differing heights.In use, with upper fold rod, middle pole, pole expansion down, the latch during pulling is inserted in the pole epimere strip hole is connected in the U type bayonet socket of upper fold rod lower end the two ends of latch.Owing between latch and the rotating shaft spring is installed, so latch can not break away from U type bayonet socket under the elastic force effect of spring.When not using, the pulling latch makes the latch two ends break away from U type bayonet socket, and folding then upper fold rod, middle pole and following pole are just packed up wheel seat so easily.
In sum, the utlity model has convenient in use expansion, the beneficial effect of when not using, conveniently turning up.
