Abstract

A portable light car lifter belongs to the technical field of automobiles, is used for lifting a car for wheel disassembly and assembly or preventing a vehicle from sinking, and solves the problem that the conventional lifter hinders continuous screw rotation. The portable light car lifter comprises a bracket of the conventional car lifter, two upper support arms hinged on the bracket, a base, two lower support arms hinged on the base, two jointed shafts rotatable in relation to the upper and the lower support arms, and a screw passing through the two jointed shafts. The utility model is more improved in that one end of the screw is square, and the component driving the screw is a crank composed of a rotating arm, with holes at one end and in the middle which are matched with the square end of the screw, and a handle mounted at the other end of the rotating arm. The utility model has the benefits of rotating the screw without the need for an operating lever to leap from side to side, enabling users to rotate the screw once for all, and lifting the car to the expected height in a short period of time.

Description

A kind of portable, lightweight car lifter

Technical field

The utility model belongs to vehicular field, is specifically related to support, the lifting device of light car.

Background technology

Existing car with automobile-used lifter (also claiming jack) by carriage, be hinged on two upper support arms on the carriage, base, be hinged on two lower support arms on the base, the all rotating hold-down arm of upper and lower relatively hold-down arm connects hinge, pass the screw rod of two jointed shafts, the operating lever that stretches into during use in the hole of screw rod one end is formed.During the lifting vehicle, rotating lever can rotating screw bolt drives up and down that hold-down arm diminishes the distance between two bearing pins, and carriage will raise with the lifting automobile.But, needing constantly to twitch extendable lever and avoid itself and ground to interfere, inconvenient continuous rotation screw rod has increased production time, delays the automobile repair progress.

Summary of the invention

The purpose of this utility model provides a kind of portable, lightweight car lifter, lifts when being used for demolition, installation wheel or depression and gives birth to car body, overcomes the deficiency of existing lifter inconvenience continuous rotation screw rod.

The utility model comprises the carriage of existing car lifter, is hinged on two upper support arms on the carriage, and base is hinged on two lower support arms on the base, and all rotating hold-down arm of upper and lower relatively hold-down arm connects hinge, passes the screw rod of two jointed shafts.The improvement of being done is that an end of screw rod is square termination, and the drive member of screw rod is the crank that is made of an end and middle part pivoted arm that the hole of matching with the square termination of screw rod arranged and the handle that is installed in the pivoted arm other end.

The utility model in use, when screw rod was overhead nearer, the radius of gyration should be little, is suitable for the galianconism shelves this moment, then screw rod embeds the hole at pivoted arm middle part; When the ground Clearance reaches corresponding height, then select long-armed shelves for use, the mating holes with screw rod conversion embedding pivoted arm end shakes handle and promptly obtains continuous propulsive effort.

The beneficial effects of the utility model are, can make things convenient for the disposable rotating screw bolt of user avoiding left and right sides play operating lever to come rotating screw bolt, make automobile reach anticipated height at short notice.

The specific embodiment

Consult among the figure 1, form by prior art and comprise carriage 4, be hinged on two upper support arms 3 on the carriage, base 8, be hinged on two lower support arms 7 on the base, all rotating hold-down arm of upper and lower relatively hold-down arm connects hinge 2, passes the car lifter of the screw rod 5 of two jointed shafts.One end of screw rod 4 is processed into square termination.Be processed into the hole 9 of matching and hole 10 at corresponding straight-bar one end of a length and middle part as pivoted arm 1, turning handle 6, the crank of formation be installed at the pivoted arm other end with the square termination of screw rod.

Claims

1. A portable light-duty car lifter, comprising a bracket, two upper support arms hinged on the bracket, a base, two lower support arms hinged on the base, upper and lower support arms that are rotatable relative to the upper and lower support arms The lower support arm is connected to the hinge shaft, and the screw passing through the two hinge shafts is characterized in that: one end of the screw rod is a square end, and the driving member of the screw rod is a rotating arm with holes matching the square end of the screw rod at one end and in the middle.
