Abstract: An anti-lock brake structure includes a brake base having a curved guiding portion formed thereon and a slidable holder. The slidable holder has a curved guiding groove defined therein for receiving the brake base. Two anti-lock inclined surfaces are positioned between the curved guiding portion and the curved guiding groove. Each anti-lock surface has a shallow section and a deeper section. Two wheel sets are disposed between the curved guiding portion and the curved guiding groove. A seat member connected to the slidable holder and receives an elastomer. A brake shoe is connected to the slidable holder. Each wheel set rolls and reciprocates between the shallow section and the deeper section of the corresponding anti-lock inclined surface, such that the brake shoe is tightly or loosely rubbed against a wheel rim of the vehicle to provide an anti-lock brake effect.

Abstract: A resilient structure includes an inner blocking unit, an outer blocking unit, and an elastomer unit. A pressured section is disposed on an outer surface of the inner blocking unit. A securing portion is disposed on an inner surface of the pressured section. Another pressured section is disposed on an outer surface of the outer blocking unit. Another securing portion is disposed on an inner surface of the pressured section. Pressure resisting sections are respectively disposed on an inner and an outer end of the elastomer unit. The pressure resisting sections are respectively confined by the securing portions disposed on the blocking units. A pressure-release portion is formed between the pressure resisting sections of the elastomer unit. The pressure-release portion absorbs pressure and store resilient force for elastic recovery.

Abstract: A control structure for a shock absorber that comprises: a base, a control assembly, and a moving assembly. The control assembly controls the motion of the moving assembly and is moved by a steel cable. A control member and a returning spring of the control assembly serve to control the motion of the moving assembly. The steel cable drives the control member to move, and the returning spring provides an elastic force for returning the relative components to their original positions. The shock absorber is defined with a working space for reception of the moving assembly. The moving assembly is provided with sliding members, and is formed with slopes form cooperating with the sliding members. When the control member drives the moving assembly to move, the pushing member of the moving assembly will push the sliding members from the deep portion to the shallow portion of the moving member, thus making the pushing rod move.

Abstract: A shock absorber for a bicycle comprises a base, a clutch assembly, a control assembly and a shock-absorbing spring. The shock-absorbing spring provides damper elastic force for the respective components of the shock absorber. The shock-absorbing function can be turned off when riding up slope, so it prevents the drag force from being increased by the up and down motion of the shock absorber. The shock-absorbing function can be turned off when riding on a horizontal road, and it can be turned off again when riding down a slope, thus preventing the increase of the front tilt angle of the bike and leading to turnover.

Abstract: A shock absorber, the shock-absorbing function of which can be turned on/off during movement and includes a basement, a clutch assembly, a control assembly and a shock-absorbing spring, the shock-absorbing spring provides damper elastic force for the respective components of the shock absorber. The shock-absorbing function can be turned off when riding up a slope, so as to prevent the drag force being increased by the up and down motion of the shock absorber.

Abstract: An oil shock absorber comprising a control assembly, a moving assembly, a damper assembly and a buffering spring, the buffering spring serving to provide elastic buffering force for respective components of the oil shock absorber, the user can adjust buffering force of the oil shock absorber and also can turn the oil shock absorber on or off according real road condition, at any time.

Abstract: The present invention relates to a door closer, in a housing of which is received a sliding cylinder, the sliding cylinder is provided with teeth on an outer periphery thereof for meshing with a gear wheel of a door shaft, a sliding cylinder interiorly formed with inner wall serves to move relative to a piston of a piston shaft. At an end of the piston shaft is provided with an oil-replenishing cylinder that serves to replenish hydraulic oil to the sliding cylinder via a one-way valve.

Abstract: An antilock brake system for a bicycle is mounted to a brake mounting bracket and generally comprising: brake shoe holder, sliding seat, brake shoe and elastic member. The brake shoe holder is formed with groove for slidably receiving the sliding seat, the brake shoe is disposed in the sliding seat, the brake shoe holder is provided with an antilock slope, and the sliding seat is correspondingly provided with a projecting portion for abutting against the antilock slope; the elastic member serves to retain the sliding seat at an end of the brake shoe holder in a rotating direction of a bicycle wheel before the brake is applied.

Abstract: A shock absorber, the shock-absorbing function of which can be enabled/disabled during movement and includes a basement, a clutch assembly, a control assembly and a shock-absorbing spring, the shock-absorbing spring provides damper elastic force for the respective components of the shock absorber.
