Item.When brake elastic slice is squeezed, positioning strip is as brake elastic slice moves downward and snaps on positioning tooth one, to realize wheel
The brake of piece.
In above-mentioned castor, the bottom plate is connected with shaft, and the shaft is interspersed on wheel carrier, the brake elastic slice
Middle part is hinged on wheel carrier, the brake portion one be located at brake elastic slice rear end, it is described brake elastic slice front end have for pair
The brake portion two that shaft is braked.Trampling while brake pedal brakes to wheel piece to shaft while can also determine
Position.
In above-mentioned castor, the bottom end of the shaft has the circular orientation edge extended downwardly, the bottom on the positioning edge
Face has a circle positioning tooth two, and the brake portion two is strip positioning strip compatible with above-mentioned positioning tooth two.Trample brake
While pedal forces the rotation of brake elastic slice and deformation to brake wheel piece, brake portion two snaps onto the positioning edge of shaft bottom end
Positioning tooth and in, thus realize entire castor direction positioning.
In above-mentioned castor, the positioning strip is several, and the root position of centrally located positioning strip is fallen
Afterwards in the root position for the positioning strip for being located at its side.It is fixed that above-mentioned positioning strip setting can better adapt to cylindric shaft bottom end
The annular setting of position tooth two, it is more preferable that card sets locating effect.
In above-mentioned castor, the inner end of the unlock pedal is hinged on wheel carrier, and the inner end of the brake pedal is hinged
On unlock pedal, the rear end of the brake elastic slice is hinged on the inner end of brake pedal, and the hinge of brake elastic slice and brake pedal
Spindle is located at brake pedal and unlocks the articulated shaft outside of pedal.When trampling brake pedal, brake pedal drive brake elastic slice to
Lower movement, and unlock pedal force and be raised above, brake elastic slice brakes wheel piece and shaft；When needing to unlock, solution is trampled
Pedal is locked, brake pedal and brake elastic slice can be made to reset, to solve the braking state of wheel piece and the positioning states of shaft.
Compared with prior art, the utility model has the advantage that
