The utility model is characterized in that the upper part of the wall of a sleeve is provided with a pin hole which is provided with a pin seat along the mouth; the pin seat is internally provided with a sliding pin; the upper part of the front end of the sliding pin is provided with a slope; the rear side of the sliding pin is provided with an eccentric wheel with a handle; one side of the eccentric wheel is provided with a torque spring and the tail part of the eccentric wheel is provided with a tethering mouth. The utility model can be used in the lifting mechanism of bicycle saddle.

Description

The steady arm of bike saddle saddle lifting bar

The utility model relates to the steady arm of bike saddle saddle lifting bar.

The lifting mechanism of bike saddle saddle is made up of manipulation device, lifting device and positioning devices.Will satisfy safe and reliable, the comfortable easy requirement of cyclist in lifting mechanism, the performance of positioning devices plays critical effect.Existing a kind of positioning devices adopts a claw type pin that has reed, the claw type pin is contained on the binding bolt of saddle, the pawl point can insert the pin-and-hole of lifting bar, claw type pin rear end connects control wire, this steady arm is simple for production, but pawl point fatigue easily causes damage, and the cyclist is sitting in and carries out lift adjustment on the saddle and relatively require great effort, and needs the cyclist to lift the buttocks saddle that disseats slightly and just regulates than being easier to.

The purpose of this utility model provides a kind of cyclist of allowing and is sitting in the same old way and needn't lifts the steady arm that buttocks can the lifting of easy adjustment seat saddle on the saddle.

The utility model comprises the sleeve pipe that holds lifting bar, it is characterized in that a pin-and-hole is arranged at casing wall top, the pin-and-hole bead is a key seat, nearly pin-and-hole is equipped with sliding pin in the key seat, sliding slightly, upper front end is an inclined-plane, there is the eccentric wheel of a band handle at the rear of sliding pin, and eccentric wheel one side has a torque spring, and the eccentric handle tail that connects has the tether mouth can connect control wire.

Because the utility model adopts sliding pin and eccentric reasonable combination, do not need the cyclist to lift buttocks and just can regulate steady arm like a cork, make the lifting energy of a saddle handy, bring comfortable and convenience to the cyclist, simultaneously because sliding pin is more abundant, durable in use, have safe and reliable advantage.

What accompanying drawing was represented is that the utility model is located at the scheme drawing that assembles with lifting bar on the bicycle saddle.1 expression sleeve pipe among the figure, the 2nd, lifting bar, 3 expression sliding pins, 4 expression eccentric wheel.

Realize that best way of the present utility model is that sliding pin 3 rear ends are provided with a steel roller, perhaps is provided with a steel roller at the eccentric wheel front end.Pin-and-hole is established on the tube wall top that concrete mode is a sleeve pipe 1, the pin-and-hole bead connects key seat, the most handy square tube of key seat, dress sliding pin 3 in the key seat, sliding pin 3 adopt the quadrangular pins and at the upper front end beveling, and be more flexible laborsaving when the roller operation is established in the sliding pin rear end, prong is made at the key seat rear portion, the rotating shaft of eccentric wheel 4 is contained in the prong flank, and the eccentric handle that connects stretches out prong, and eccentric wheel connects to be established the torque spring wheel limit that eccentric wheel is far away apart from rotating shaft and withstand on sliding pin 3 rear ends between handle and the key seat.Sliding pin 3 front ends push up to the pin-and-hole of lifting bar 2 be the lockable lifting bar, when the sliding pin rear is pulled on the eccentric wheel 4 wheel limit nearer apart from rotating shaft, eccentric wheel loosens the pushing tow sliding pin, sliding pin 3 is retracted into key seat under the pushing of the gravity of lifting bar 2, the obstruction that lifting bar 2 is not subjected to sliding pin is liftable then.

Claims
