Abstract

The utility model relates to an improved electric horizontal jack composed of a pressing cylinder, a hydraulic cylinder, an eccentric block, a connecting rod, a swing arm, a motor, an air compressor, etc. The utility model is characterized in that a speed reduction gear group is arranged between the motor and the eccentric block to form a speed reduction transmission device. After installed, the speed reduction gear group is engaged with a master gear on the motor, and a speed reduction gear at the end of the speed reduction gear group extends an eccentric shaft rod which can drive the eccentric block to be linked with the connecting rod. The swing arm is a strip-shaped swing arm in a Z shape, the swing arm is driven by the connecting rod to generate upward and downward press force to a pressing shaft rod, and a heavy article can be jacked by a jacking shaft. When the utility model is used, the motor operating at high speed can be well matched with the gradually lifting jacking shaft, so that the motor is prevented from being burned and a fuse is prevented from being burned out.

Description

Electric horizontal jack

The utility model relates to a kind of jack device technology, particularly a kind of improved electronic horizontal jack with new-type drive mechanism.

Current social various automotives extensively are used as by people and are ridden instead of walk or the instrument of goods transport uses, meet human negligence, unexpected traffic accident or physical damage by chance, in the time of must repairing, various motor-driven many wheels vehicle that can't stir easily in the face of manpower, but the labour saving machine equipment that obviously needs a kind of manpower ease of Use to be convenient to repair: i.e. jack device with the jack-up vehicle.But early stage horizontal jack device all is to adopt the lever hydraulic operation with manpower, and the apical axis (big piston) in the modulated pressure tube rises and the jack-up weight gradually.This kind is with the device of manual operation, and not only time-consuming and effort is quite fallen behind.So someone improves early stage manpower jack, designs DYN dynamic jack.This device is to push shift motion by directly driving swing arm through connecting rod as the motor of propulsion source do lifting, from and last the drive as the ram pot big piston of execution unit do the jack-up action and constitute.Adopt the electrodynamic type design to have very much progress than manual operation certainly, but existing electronic horizontal jack finds still to exist following drawback extremely to be overcome through actual use:

1, the power that is produced as the motor (being provided on the air compressor) of propulsion source is the output under a kind of high-speed operation state, when high-speed operation power directly when connecting rod drives swing arm and makes lifting push type displacement action, be difficult to form shortcoming poor for applicability with gradually the apical axis of preface rising (big piston) coupling is good by hydraulic pressure.

2, the high speed propulsion source motor with air compressor needs the coupling design of the apical axis of rising (big piston) in proper order as directly driving in the ram pot, often cause complete machine to cooperate imbalance, running has some setbacks, with cause the propulsion source motor to burn or battery socket insure the silk because of moment high electric current blow.

The purpose of this utility model is the defective that will overcome the said goods technology, thereby designs a kind of improved electronic horizontal jack with new-type reducing transmission structure.

The same with the electronic horizontal jack of prior art, its actuating unit partly has by pressure cylinder, ram pot, base, be provided with by pressure cylinder inside and push axostylus axostyle (valve piston), ram pot inside is provided with apical axis (big piston), the base appropriate location has protruded out contiguous block, push the axostylus axostyle top and be socketed with swing arm, the other end of the hinge joint of an end of swing arm and connecting rod, swing arm is hinged with and is connected nest plate, and it is hinged to connect nest plate and above-mentioned contiguous block.Its propulsion source partly has motor, motor can be accepted electric power and supply with power, and motor is assemblied on the air compressor, and the body of air compressor borrows supporting seat to be fixed on the base, be provided with eccentric block in addition, but eccentric block and connecting rod one end are hinged and the drivening rod action.Its constructional feature mainly is to be equipped with a reduction gear apparatus between as the motor of propulsion source and eccentric block: i.e. train of reduction gears driving device, thus realize that deceleration transmission is to reach the design goal of motor and apical axis matched well.
