Definitions

  • the invention relates to a handlebar, in particular to a self-locking folding handlebar.
  • handlebars for bicycles, tricycles, motorcycles, motorcycles, etc., for example, bicycles:
  • the left and right handlebars of the fixed handlebar are fixed laterally on the front arm, and the front arm is fixed on the nose shaft.
  • the fixed handlebar is firmly combined without looseness.
  • the disadvantage is that the bicycle occupies a large space when parked.
  • the folding handlebars used for folding bicycles mainly include the following
  • Plug-in folding handle After the left and right handlebars are locked and closed in the front arm, you need to insert the plug provided on the side of the lock body to insert and fix the handle.
  • the insertion pin used in the one-way insertion method is an equal-diameter cylinder, and the cylinder is in sliding engagement with the keyhole, and the gap of the sliding fit is increased with the use of the vehicle, so that the original technology of the handlebar sleeve is matched. The state changes, which in turn affects the stability of the bicycle when riding, and even creates safety problems.
  • Integral folding handlebars When the handlebars of some folding bicycles are folded, the handles are folded back on the vehicle body as a whole. The folded handlebars also need to adjust the relative parallel angle between the handlebar structure and the frame. This kind of operation is troublesome. If the handle angle and pressure are not adjusted properly, during the riding process, the handlebar will loosen the lock body structure due to the vibration stress, causing a certain degree of safety hazard.
  • Threaded handlebar The handlebar is connected with the front arm by threading. However, the separated handlebars are not easy to collect when they are not placed. In addition, the threaded handlebars are troublesome to install, and the movement is slow. The most deadly is the handlebar thread. The damage directly makes the handlebars unable to be installed and practical. Summary of the invention:
  • the self-locking folding handlebar capable of achieving the above purpose includes a left and a right handlebar and a front arm connected to the tail ends of the left and right handlebars, the difference being: the left and right handlebars are hinged on the front arm of the vehicle.
  • the left and right handlebars are parallel to each other, and the left and right handlebars are rotatable in a longitudinal vertical plane to achieve horizontal closure and vertical folding, or to rotate in a horizontal horizontal plane to achieve horizontal closure and parallel folding.
  • the left end of the left and right handlebars are provided with semi-circular holes and semi-conical pins which are formed by concentric circles and concentric taper pins when horizontally closed, and the closed circular holes are the axial holes of the conical pins, the axial line and the left,
  • the rotation axis of the right handlebar is parallel; a guide rod is fixed on the inner end of the front arm, the circular hole and the conical pin shaft, and the guide rod is matched with the circular hole of the conical pin, and the guide rod is further provided with an elastic mechanism.
  • Push and cone A pin-fitted taper sleeve; a clutch mechanism for disengaging the taper sleeve from the taper pin is also provided on the front arm.
  • the rotation direction of the left and right handlebars forms a 90 degree movement angle with the elastically moving taper sleeve, and the sleeve sleeve adopts a self-locking fastening manner to the closed cone pin under the action of the elastic force.
  • the circular hole of the tapered pin and the approximately rigid contact of the guide rod ensure the overall rigidity and smooth safety of the folding handlebar during the riding state and the front arm.
  • the taper sleeve loses control of the taper pin under the manipulation of the clutch mechanism, and the left and right handlebars rotate to form a folded state.
  • synchronous teeth are further provided at the tail ends of the left and right handlebars, and the synchronous teeth are preferably sector-shaped synchronous teeth, the axis center of the sector-shaped synchronous teeth and the left, The rotation axis of the right car coincides.
  • the elastic structure is a compression spring, and the compression spring is set on the guide rod and press-fitted on the rear end of the sleeve o
  • the clutch mechanism includes a joystick, and the lever portion of the joystick is hinged on the arm of the vehicle.
  • One end of the joystick is connected with the taper sleeve.
  • the other end of the joystick is moved to force the taper sleeve to overcome The compression spring force moves to disengage the taper sleeve from the taper pin. If the left and right handlebars are vertically folded, the handlebar will automatically rotate from the horizontal closed state to the vertical folded state under the action of gravity; if the horizontal folding mode is adopted, only the left and right handlebars can be toggled. The two handlebars are folded back at the same time.
  • an outwardly flared oblique wing opposite to the taper of the taper sleeve may be provided at a side of the taper sleeve at a position corresponding to the closed semi-conical pin.
  • the square-shaped elastic locking tongue of the anti-theft lock is arranged in parallel with the guide rod and pressed on the left and right handlebars, and the keyhole is opened on the left and right handlebars. When closed, it corresponds to the elastic locking tongue. When it is closed, the elastic locking tongue automatically snaps into the locking hole, and the left and right handlebars are locked in the folded state. To restore the closing of the left and right handlebars, the key needs to be used to open the anti-theft. The lock releases the elastic locking tongue from the locking hole.
  • the elastic locking tongue is close to the guiding rod, when the tool is extended into the front arm arm and the elastic locking tongue, it is easy to bend the guiding rod at the same time, even if the elastic locking tongue has been opened, due to the deformation of the guiding rod, the sleeve It will be stuck and cannot move. It can't lock the tapered pin of the left and right handlebars. In this case, the left and right handlebars can be closed but cannot be locked, and the vehicle cannot ride.
  • the built-in tensile wheel lock is placed in the folded position of the vehicle. When the handlebar is in the folded state, the built-in tensile wheel lock can be pulled out in the tube of the left and right vehicles, and the vehicle is locked through the front wheel rim, making the vehicle impossible to implement. .

Abstract

L'invention concerne des guidons pliables à autoblocage qui comprennent un guidon gauche (1), un guidon droit (2) et un boîtier (3) en communication avec les extrémités des guidons gauche et droit (1, 2), lesquels tournent de manière symétrique et synchrone entre une position dépliée horizontale et une position pliée verticale. En position dépliée, un orifice semi-circulaire et une goupille semi-conique (4) des extrémités des guidons gauche et droit (1,2) forment, une fois en prise, un orifice circulaire concentrique et une goupille conique concentrique dans le sens transversal. Une douille de réduction (6) est accouplée élastiquement à demeure dans le sens transversal avec la goupille conique concentrique, avec pour effet d'autobloquer les guidons gauche et droit (1, 2). Une barre de commande (7) permet de séparer la douille de réduction (6) de la goupille conique de manière à mettre les guidons gauche et droit (1, 2) en position pliée verticale sous l'effet de leur poids.
