Description
Technical field
The utility model relates to a kind of with car scissor-like jack, especially a kind of scissor-like jack of structure optimization.
Background technology
various family-sized car at present with car supporting mostly adopt for the hoisting equipment of vehicle belonging to maintenance maintenance jacking be Cheng Jian Shrink shape and the jack of the framing members such as tool complete thread pair, supporting arm, this scissor-like jack generally all has paired upper supporting arm group and paired lower support arm group, and upper supporting arm group is to come directly towards the top support of parts as upper hinge hinge, lower support arm group then stretches using integrated base member both sides to upper overturning and forms the paired bottom bracket of epirelief as underneath hinges hinge, hinge block is passed through between upper supporting arm group and lower support arm group, hinge extends nut, thrust baring, screw mandrel and screw mandrel limit casing are formed by combining, the rotation of the screw thread pair of this scissor-like jack only relies on and uses operating handle to drive, when making adjustment to the i.e. jack idle path in non-lifting, the rotation of this stiff torsion screw mandrel is wasted time and energy and very inharmonious, often direct using simple top support as support during this its bearing load of traditional scissor-like jack, namely use through once or seldom several times can form support local, top and produce permanent deformation and cause and affect result of use, again, jack, as the kit of family-sized car, is constantly changed for a long time in the quality and price competition of the marketization, is that the cost location in its structural machinability or pure processing technology all allows people spend all scheming.
Summary of the invention
In view of the comprehensive consideration to above-mentioned several factor, technical personnel actively proposes a kind of mentality of designing of optimizing structure in earnest, one is for the outer-hexagonal termination of the screw mandrel of scissor-like jack makes supporting plastic handle to measure, two is add hat to the top of weakness, and with the leftover pieces of other products in factory, bending and drawing and forming tray member, makes the top parts of this jack more powerful, three is set about changing long-term next unalterable integrated simple base support body, the drawing process of simplified structure part, traditional base support body is divided into two, " U " holder combination of the leftover pieces blanking forming produced in being produced by relatively shaping easy base plate superposition other products becomes novel base support parts, make no matter this scissor-like jack reconfiguring design is to torsion stiffness, the raising of the defects level such as intensity, still the good performance that enhances the competitiveness is reduced costs, according to analysis, the increase of plastic handle only makes cost approximately add several sharing money, how much setting up of top upper fray part only increases, and the split of base builds, then cut down expenses nearly one yuan, the economic benefit of bringing to number in this type product of ten million platform is thus then considerable.
Above-mentioned purpose of the present utility model is achieved in that a kind of scissor-like jack of structure optimization comprises top, upper supporting arm group, lower support arm group, hinge block, hinge extension nut, thrust baring, screw mandrel parts, base support, it is characterized in that: described Scissoring jacking header support is implemented to rotate with upper left supporting arm and upper right supporting arm respectively with the first revolute pair, the second revolute pair and connected; Base support is implemented to be rotationally connected with lower-left supporting arm and bottom right supporting arm with the 3rd revolute pair, the 4th revolute pair respectively; Hinge nut implements being rotationally connected of upper left supporting arm and lower-left supporting arm; Hinge block is implemented upper right supporting arm and is connected with the rotation of bottom right supporting arm; The outside thread of screw mandrel and the negative thread of hinge nut form screw thread pair; Thrust baring is provided with between hinge block locating surface and the screw mandrel shaft shoulder; Next-door neighbour screw mandrel shaft shoulder place is provided with screw mandrel outer-hexagonal end section; Cylindrical section and the screw mandrel outer-hexagonal end section place of the screw mandrel shaft shoulder have securely coordinated screw mandrel manual type swing handle; Riveted joint tray member has been connected firmly above the support of described top; Described base support and base plate connect firmly to press.
