Abstract
The invention discloses a spiral shear jack comprising a base made by integrally forging a steel channel and a head made by forging a U-shaped member. Left and right lower supports are hinged to the base. The lower ends of the left and right lower supports are provided with positive teeth and reverse teeth, respectively. The lower ends of the left and right lower supports are hinged before meshing with the positive and reverse teeth. The lower portion of the head is hinged to left and right upper supports. The upper ends of the left and right upper supports are hinged and mesh with the positive and reverse teeth. A wire thread insert is hinged between the left upper support and the left lower support. A special-shaped support shaft is hinged between the right upper support and the right lower support. A fixing sleeve is riveted to the outside of the special-shaped support shaft. The spiral shear jack is reasonable in structural design, convenient to operate and high in universality; the parts have no contact during moving.
Description
Technical field
The present invention relates to jack field, specifically belong to a kind of spiral shearing type jack.
Background technology
Scissor-like jack is bracket jack again, light and fast, be domestic each large automotive plant with car product, principle is had nothing in common with each other.The upper rack posts be made up of sheet metal and lower fulcrum bar form.The cross-sectional plane of upper rack posts and lower fulcrum bar teeth portion and near the cross-sectional plane of part be the rectangle of openings at one side, the metal sheet on opening both sides bends inwards.Tooth on upper rack posts and lower fulcrum bar is that the metal sheet that bent by opening both sides is made, and this kind of jack generalization degree is not high, uses inconvenience.
Summary of the invention
The object of this invention is to provide a kind of spiral shearing type jack, reasonable in design, easy to operate, generalization degree is high, mutually can not touch in all parts motion process.
Technical scheme of the present invention is as follows:
A kind of spiral shearing type jack, comprises the base of one channel-section steel forging molding, the top of U-shaped part forging molding, base is hinged with a left side, right lower bracket, left, right lower bracket lower end is just respectively equipped with, anti-tooth, left lower bracket and right lower bracket lower end hinged after and by just, anti-tooth engages each other, and top lower hinge has a left side, right upper bracket, left, right upper bracket upper end thereof also just passes through, anti-tooth engages each other, swivel nut is hinged with between upper left support and left lower bracket, special-shaped pivot shaft is hinged with between right upper bracket and right lower bracket, abnormity pivot shaft rivets fixed cover outward, the radial direction of described swivel nut and special-shaped pivot shaft is respectively equipped with through hole, swivel nut is set with U-shaped fixed support, the described inside otch in fixed support two sides forms a square groove, U-shaped fixed support bottom surface is provided with bottom outlet, U-shaped fixed support is embedded in square nut, described swivel nut radial direction is provided with screw, and screw mandrel is successively through surface bearing, abnormity pivot shaft, fixed cover, fixed support bottom outlet, screw through screw, make jack as minimum altitude.
Adopt fixed support coupling nut structure, square nut embeds within fixed support draw-in groove, increases tapped bore degree of depth hoisting nut intensity, shortens screw mandrel length, reduce the maximum placement space diameter of jack certain height, jack can be placed with car spare tyre kind.
Described left and right lower bracket reinforced rib entirety is turned up, the overall varus of left and right upper bracket reinforced rib.
Described base and left and right lower bracket, top and left and right upper bracket riveted position have employed beading.
Described upper and lower rack pin shaft rotation hole position and pin-hinges position have employed hole flanging reinforced rib.
Described left and right upper bracket, left and right lower bracket is provided with lightening hole.
The rated load of jack of the present invention: 1500Kg; Maximum lift height: >=425mm; Minimum fold height :≤115mm; Maximum placement space diameter: 390 ± 4mm; Maximum overall length≤480mm, top generates structure, promotes top intensity, and pin hole place, top reinforced rib prevents top from coordinating with upper bracket and causes paint scratch.Avoid jack to come directly towards in lifting process and cause paint scratch with lower bracket, base and upper bracket friction.Reasonable in design of the present invention, easy to operate, generalization degree is high, mutually can not touch in all parts motion process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is Lead screw transmission structure figure.
