Abstract
The invention discloses a four-connecting-rod electric jack which comprises a bracket, upper connecting rods, lower connecting rods, a base, a screw rod, a pin nut and a speed reducing motor, wherein the upper connecting rods and the lower connecting rods form a four-connecting-rod mechanism of which one end is hinged on the bracket and the other end is hinged on the base; the pin nut is arranged at the hinged part of the upper and lower connecting rods on the right side; the speed reducing motor is arranged at the hinged part of the upper and lower connecting rods on the left side; one end of the screw rod passes through a shell of the speed reducing motor and is driven to rotate by the speed reducing motor; the other end of the screw rod passes through a screw hole in the middle of the pin nut; and when the screw rod rotates, the four-connecting-rod mechanism is pulled through the movement of the pin nut so as to lift the bracket. Two travel switches are arranged, thus when the bracket is lifted to the set position, power is cut off to prevent the screw rod from being damaged by false operation. Multiple mutually-meshed gear teeth are arranged between the two groups of upper and lower connecting rods so as to prevent the bracket from falling due to the failure of the screw rod. The four-connecting-rod electric jack disclosed by the invention is a special tool designed for small automobiles, is easy and convenient to operate and saves labor.
Description
Technical field
The present invention relates to a kind of electronic jack, specifically refer to the electronic jack of four connecting rods.
Background technology
Existing automobile-used jack is a lot, but the electronic jack in labour-saving seldom.Chinese patent application number is 200420080126.6 " a kind of electronic jack ", has used inside and outside two cover transmissions, and middle the swivel nut 6 that possesses internal and external screw thread is simultaneously made quite complicated, and intensity also is difficult to assurance; Lack inhibiting device on the integral structure, there is hidden danger in secure context; Application number is " electronic internal tooth screw mandrel jack " complex structure of 200920304985.1, maintenance difficult, manufacturing cost height.The both directly heads on strong point lifting by screw mandrel, and during the screw mandrel wearing and tearing, replacement cost is lower than purchase cost hardly.Through in-depth study, the applicant has broken through conventional thinking, uses the diverse technical scheme of a cover to substitute, and therefore this case produces.
Summary of the invention
The object of the present invention is to provide a kind of electronic jack of four connecting rods simple in structure, easy to maintenance.
To achieve these goals, technical scheme of the present invention is as follows:
The electronic jack of four connecting rods comprises carriage, boxed rod, lower link, base, screw mandrel, pin nut, reducing motor, the centre one end hinge joint of described boxed rod and lower link is in the same place, the upper end hinge of boxed rod is on carriage, and the lower end of lower link links on base; Described boxed rod and lower link are divided into left and right two groups, and boxed rod hinge joint place right and the lower link right side is provided with the pin nut, and hinge joint place on another a group boxed rod left side and a lower link left side is provided with reducing motor; One end of screw mandrel passes the shell of reducing motor, and rotation under the gear pair of reducing motor drives, and the other end passes the screw in the middle of the pin nut, and the screw of the Acme thread of screw mandrel and pin nut is adaptive; Be provided with travel switch at lower link left side medial surface, when a boxed rod left side can be by the button of lower stroke switch when being depressed into desired location; Also be provided with travel switch on base, when lower link gave rise to desired location, the projection on the lower link can be by the button of lower stroke switch; Two place's travel switches all with between the reducing motor have circuit to be connected, and cut off the power supply of reducing motor when button actions, and several connecting rods that prevent to link are near stretching position the time, and stroke reaches an end, and screw mandrel is also being forced rotation, and causes screw mandrel to damage.Hinge joint is provided with intermeshing several gear teeth in the top between two boxed rods on the carriage, hinge joint also is provided with intermeshing several gear teeth in its lower end between two lower links on the base, play the effect of gear centering block, this is in order to prevent just in case screw mandrel when losing efficacy because of wearing and tearing, the self-locking action of gear can stationary links the position, prop up carriage can be not suddenly down slump and the thing of hurting sb.'s feelings;
Screw mandrel is provided with the square hole cylinder on that top of passing reducing motor, also can replace motor to come rotary screw rod with cap key under the situation of power shortage.
The electronic jack of four connecting rods is that a miniature car design-calculated that aims at below 7 changes tire tool, and is easy and simple to handle, uses the 12V direct supply power taking of Cigarette lighter or automobile storage battery, laborsaving, response is fast; The present invention is simple in structure, reliable and stable, screw mandrel and the nut supporting with it provide as consumable accessory, and client oneself changes, and is easy to maintenance.

Description of reference numerals:
1 carriage, the 2 boxed rod right sides, 21 gear teeth A, 3 boxed rod left sides, the 4 lower link right sides, 41 gear teeth B, 5 lower link left sides, 6 reducing motors, 7 bases, 8 travel switches, 9 screw mandrels, 91 square hole cylinders, 10 pin nuts.
The specific embodiment
Below by drawings and Examples the present invention is further elaborated.
As shown in Figures 1 to 4, the electronic jack of four connecting rods comprises carriage 1, the boxed rod right side 2, a boxed rod left side 3, the lower link right side 4, a lower link left side 5, reducing motor 6, base 7, travel switch 8, screw mandrel 9, pin nut 10, its working process is: jack is placed on appropriate location under the car, on automobile cigarette lighter or automobile storage battery, connect the power supply of reducing motor 6, and control reducing motor 6 rotations, screw mandrel 9 rotates under reducing motor 6 drives synchronously, the rotation of screw mandrel 9 has spurred pin nut 10, and it is moved on screw mandrel 9, the four-bar linkage action is forced on the mobile boxed rod right 2 and the lower link right side 4 that has spurred the right side of pin nut 10.When being rotated in the forward, the four-bar linkage lateral contraction, carriage 1 parallel slowly upwards lifting, automobile is lifted when playing suitable height, cut off the electricity supply, be convenient to changing of tire or carry out other operations.When operation is finished, then reducing motor 6 backward rotation, make screw mandrel 9 promote pin nut 10 and oppositely move, force the four-bar linkage lateral extent, carriage 1 slowly descends, and until breaking away from the automobile strong point, the electronic jack of four connecting rods is removed, and puts into the tool box.
Because user's attention often concentrates in the lifting of automobile, usually neglected the change in location of connecting rod mechanism, when carriage 1 position is too high or too low, rotation is also being forced because of the not enough screw mandrel 9 of stroke in the capital, this is can very fast engaging piece bit loss screw mandrel 9 and pin nut 10 bad, thus 2 travel switches 8 need be set, before carriage 1 is near end position, four-bar linkage is just cut off the electricity supply by travel switch 8, and reducing motor 6 is in time stopped.
Gear teeth A21 and gear teeth B41 consider the set safety mechanism of safety, utilize the self-lock mechanism of gear, just in case screw mandrel 9 or pin nut 10 during because of wear out failure, can also support mutually between the connecting rod, prevent carriage 1 unexpected slump.
Just in case power supply can not the time spent, also available socket wrench puts in square hole cylinder 91, comes rotary screw rod 9 with M/C, vehicle hoisting or decline.
