Abstract
A dual-purpose electric jack comprises a jacking mechanism, an intermediate transmission mechanism and a power mechanism. The dual-purpose electric jack is characterized in that the power mechanism comprises a casing body and a motor arranged inside the casing body; a power output shaft of the motor is fixedly and integrally connected with a power main shaft; and connection structures capable of mutually matching in gap inserting manner are arranged between the power main shaft and the intermediate transmission mechanism. When the power mechanism is integrally connected with the intermediate transmission mechanism in inserting manner, the power mechanism provides work power for the jacking mechanism. When the power mechanism and the intermediate transmission mechanism are disengaged, the power mechanism can be used for other purposes, thereby expanding the functions of a traditional electric jack.
Description
Technical field
The utility model relates to a kind of electronic jack, relates in particular to a kind of dual-purpose electric jack double-duty that has.
Background technology
Electronic jack is used for the top and lifts heavy thing, certain height is lifted on the weight top, so that operation is carried out in the bottom of weight.Generally all from having electronic jack, when the automobile et out of order, auto body is lifted, on the existing automobile so that automobile is simply keeped in repair.The structure of existing electronic jack generally comprises actuating unit, intermediate transmission mechanism and top and lifts mechanism, and these mechanisms are integrated and link together.Though the structural compactness of the electronic jack of this version is good, it can only be lifted mechanism as the top merely and use, and can not use it for anything else in addition.And when the automobile et out of order need carry out simplified overhauling, though automobile need be elevated vehicle body, often need the binding bolt of some parts is dismantled, so that change to damaging parts (as tire).Be not equipped with the electrodynamic type bolt disassembling tool on the existing automobile, when some binding bolts or nut are dismantled, often need manpower to carry out, this is for most women drivers, the operation of manpower dismounting binding bolt often is difficult to bear, and electronic jack has also just lost using value.If on automobile, be equipped with electrodynamic type bolt or nut withdrawing device again, because electrodynamic type bolt or nut withdrawing device itself have certain weight, often be placed on the automobile on the one hand, can increase the fuel oil consumption of automobile; On the other hand, electrodynamic type bolt or nut withdrawing device itself have certain volume, and this also can take the storage space on the automobile.Therefore, the electronic jack of existing structure, it uses inconvenience apparent.
The utility model content
For overcoming the above-mentioned defective that existing electronic jack, the particularly electronic jack of in-vehicle are had, the purpose of this utility model is: provide a kind of and be easy to carry, light dual-purpose electric jack laborsaving, easy to use in use.
For solving the problems of the technologies described above, the technical solution of the utility model: a kind of dual-purpose electric jack, comprise top act mechanism, intermediate transmission mechanism and actuating unit, it is characterized in that, described actuating unit comprises housing and is located at the interior motor of housing, motor power output shaft and power spindle are fixed together, and are provided with the draw bail of pegging graft and cooperate in gap mutually between power spindle and the intermediate transmission mechanism.The power of actuating unit is passed to the top by intermediate transmission mechanism to be lifted in the mechanism, and the top is lifted mechanism and accepted to start working behind the power, and certain height is lifted on the weight top.The described draw bail that can peg graft mutually and cooperate, be meant that actuating unit and intermediate transmission mechanism can break away from mutually or socket connection is in the same place, after both are linked together, power on the actuating unit can be delivered to the top by intermediate transmission mechanism and lift in the mechanism, after both were separated, actuating unit can use it for anything else in addition.As can centrifugal driving end being set, binding bolt or nut are dismantled or assembled by actuating unit in the power spindle end of actuating unit.The top is lifted the rising of mechanism or is descended and all provided by actuating unit, needs to be provided with change-over swith on actuating unit, so that the forward and backward of actuating unit, this has also adapted to the requirement that turns to of the dismounting of binding bolt or nut and assembling.Described draw bail generally be the non-circular shape that cooperatively interacts plush copper and shrinkage pool, the matching relationship between plush copper and the shrinkage pool should be free-running fit.
This dual-purpose electric jack also can be done following further optimization:
Described top is lifted mechanism and is comprised shell and be located at shell interior driving screw, top screw rod and several middle screw rod that these screw coaxials connect together with being threaded.
The outside of described screw rod is provided with the hollow protecting jacket that number equates with middle screw rod, and these protecting jackets are coaxial to connect together, and protecting jacket and top screw rod circumferentially are linked together regularly, circumferential captive joint between adjacent two protecting jackets.
The elevation profile of described shell is " several " font, is provided with two intermeshing transmission gears at the bottom position place of shell, and one of them gear and driving screw are connected, and another gear and intermediate transmission mechanism are connected.
Be respectively equipped with plush copper between the end of adjacent two screw rods in the described screw rod, between the mutually close end face of a pair of plush copper, be provided with outstanding steel ball.
Described housing profile is " pistol " shape.
Described intermediate transmission mechanism comprises gear case, is penetrated with a worm screw on gear case, and the end of worm screw is projected into the outside of gear case, and described draw bail is between the jag of power spindle and worm screw.
Be provided with the worm gear that is meshed with worm screw in the described gear case, set transmission main shaft is fixed together in worm gear and the gear case.
Therefore, the beneficial effects of the utility model:
Actuating unit can be separated from or be plugged on mutually with intermediate transmission mechanism, when lifting mechanism's work on the top, actuating unit is lifted the operation power source of mechanism as the top, and mechanism is lifted after hours in the top, actuating unit can be separated with intermediate transmission mechanism, actuating unit can use it for anything else in addition, as using the propulsion source of actuating unit as dismounting or assembling binding bolt or nut.Like this, cast anchor when needing simplified overhauling, both can realize raising of vehicle body at automobile, do not need to utilize manpower that the binding bolt of corresponding component is carried out operation again, expanded the function of conventional electric jack, made things convenient for the use to electronic jack, this is particularly useful for women driver.
