Description
Technical field
The present invention relates to a kind of scissor-like jack, specifically refer to a kind of for offroad vehicle or urban off-road vehicle or bottom
The high-order scissor-like jack of the combination band of the higher various kart of disk.
Background technology
Scissor-like jack is the driver's tool applied to various cars or kart.In recent years, between car with
The great development of comfort type urban off-road vehicle between offroad vehicle, also faces as what is be adapted therewith with the supporting scissor-like jack of car
Update or by considering that new demand is redesigned.Traditional scissor-like jack is applicable to the relatively low vapour in jacking chassis
Car, and the urban off-road vehicle emerged in multitude is higher due to chassis, if again with the old-fashioned car supporting this city of scissor-like jack
City's offroad vehicle, then can cause non-work done lift increase during jacking automobile, i.e., storage of traditional scissor-like jack from extreme lower position
The idle stroke of the unsupported work done for the jack that state is risen to needed for offroad vehicle Jacking point position is greatly increased, and wastes operator
The operating time of member and energy；If due to urban off-road vehicle chassis position it is high the characteristics of, by the scissors thousand of same authorized load capacity
The cursor on jin top is lengthened, and the moment of resistance of scissor-like jack during jacking automobile can be greatly increased, so as to can increase using a lot of
The metal material of high-quality, the scissor-like jack so designed and manufactured will be wasted very heavy, very much, also just be seemed not with car is supporting
It is so light and handy, and the increase of cost price can be nearly 2 times of former car scissor-like jack.
The content of the invention
The task of the present invention is the deficiency for above-mentioned background technology and correlation technique scheme, considers again for cross-country
Car with the supporting scissor-like jack of car cost performance.Engineers are by the preferred rule for designing each link, it is believed that：Determine to adopt first
Two sets of combination cursor structures and the associated threads auxiliary structure up and down of the scissor-like jack of traditional same nominal bearing capacity, do not make
Change, to ensure to operate torsional moment of the two sets of combination cursors up and down when being rotated by power screw thread pair of jack not increase
Plus, realizing the basic cost of such jack does not increase；Second, fully appropriate this height for improving jacking header part of concern
The oneself height of degree and base support, forces down cost increase as far as possible, and fully ensures structural member intensity, and next further expands this
The necessary functional category of novel scissor jack is planted, the slightly increasing of base support cost is dexterously made up with additional memory function
Plus, so new technical scheme makes scissor-like jack realize band of the combination with car, makes the Scissoring jacking header position of the program
Putting just can be just relatively reasonablely small the distance between the Jacking point of urban off-road vehicle in its lowest order, and is easy to performance scissors
The effect of the normal moment of torsion of jack, user also just seems more free and relaxed during operation jacking automobile.
The above-mentioned purpose of the present invention is achieved through the following technical solutions：A kind of high-order scissors for combining band are very heavy
Top, including top combination cursor, bottom combination cursor, screw thread pair functional unit, top part and base member, its feature
It is：Top part is combined cursor with top and coordinated respectively with the first revolute pair and the connection of the second revolute pair, base member difference
Coordinated with the 3rd revolute pair and the connection of the 4th revolute pair, top support crimps integral shape structure with equalizing bed in top end；Top
The both sides of support are respectively equipped with the first high-order Body of pillar and the second high-order Body of pillar；Base member is provided with base member high
Position bearing and band assembly；First is provided with the symmetrical fore-and-aft plane position of the upper convex bottom panel of the high-order bearing of base member
Positioning hole and the second positioning hole；First is provided with band assembly to pass through hole, second pass through the tray plate in hole, and in support
The both sides of plate are respectively equipped with the first lock buckling groove, the second lock buckling groove, the 3rd lock buckling groove and the 4th lock buckling groove；First locking pin and
Second locking pin passed through respectively with first hole, second pass through hole implement gap cooperation；Band is tightly around knot by the first lock
Rationed marketing post and the second stop pin column combination into circular curved surface on；Pressure has steel wire latch closure above band, and steel wire ring is buckled
The first locking cross bar linked closely together with the first lock buckling groove, the second lock buckling groove, the second locking cross bar and the 3rd lock buckling groove, the 4th lock
Catching groove also links closely together；The upper convex bottom panel knot of the locating surface of the tray plate of band assembly and the high-order bearing of base member
Close, the first modular radial elasticity Lock buckle passes through the first positioning hole, the second modular radial elasticity Lock buckle, which passes through second, to be determined
Position hole, both of which reverse locking base member high position bearing, to realize the one of the high-order bearing of band assembly and base member
It is coupled.
Wherein, the first flanging stiffener, the second flanging is set up on the first high-order Body of pillar of top support to strengthen
Component and the first beading formula stiffener, set up the 3rd flanging stiffener, Fourth Fold reinforcement on the second high-order Body of pillar
Component and the second beading formula stiffener.
Wherein, the first U-shaped groove is provided with the middle of equalizing bed, upper surface both sides are respectively equipped with left side extension board and right side extension
Plate.
Wherein, U-shaped outer lug boss of the crown center provided with the 2nd U connected in stars and equalizing bed of top support coordinates；Come directly towards support
N shape die cavities are available for the left side extension board and right side extension board of equalizing bed to bend and be involved in.
Wherein, the first locking pin connected firmly in band assembly with tray plate and the respective bottom of the second locking pin
The elastic Lock buckle of the first modular radial and the elastic Lock buckle of the second modular radial on be respectively equipped with four it is circumferentially uniform
Reverse clasp.
The present invention has an advantageous effect in that compared with prior art：Pass through the top to traditional same bearer amount scissor-like jack
Increasing and structural strengthening design for head part, makes full use of the plate scrap of all kinds of scissor-like jacks generations of plant produced to be formed
Equalizing bed design of part, the intrinsic less stable of higher top support is overcome using each flanging stiffener and beading formula stiffener
And the low significant deficiency of anti-torsional strength；By designing band assembly and it being coupled into the high-order bearing of base member, make this
Jack base excess room formed by increasing is fully used so that the cost performance of the product is significantly improved.
