Description
Technical field
The utility model is related to a kind of jack, more particularly to a kind of scissor-like jack.
Background technology
Scissor-like jack is known and is widely used in lifting vehicle.This jack is sometimes referred to as spirally
Jack.Its Basic Design and operating principle have also been employed that a period of time.The improvement done on these jack is general
It is to be carried out on thread spindle or on the gudgeon that the thread spindle is connected on part.In order to negative with these jack liftings
Carrying needs sizable active force, or, in other words, lifting rate is reduced so as to reduce the demand of power.
However, mode during traditional scissor-like jack lifting object by rotating threaded shaft changes the mode of upper underarm angle
To realize, the height of regulation is limited by upper underarm brachium, to increase rising height, certainly will increase the arm of upper underarm
Long, brachium jack more long adjusts still higher to height during extreme lower position, needs to consider extreme lower position again not for some
Be applicable, and traditional scissor-like jack there is a problem of the rate of climb it is slow, it is necessary to by object be lifted to setting height need it is more long
Time, therefore also consumes the active force of more people.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of scissor-like jack, to improve lifting
The speed of object, improves the ratio of jack extreme higher position and extreme lower position.
For the attainment of one's purpose, the technical scheme of the utility model offer is：
A kind of scissor-like jack that the utility model is related to, it includes two upper arm, two underarms, left flap, right hinges
Carrier bar, fork arm nut and screw mandrel, two bottoms of upper arm are hinged with left flap and right flap respectively, two tops of underarm
It is hinged with left flap and right flap respectively, fork arm nut is fixed on right flap, screw mandrel runs through left flap and fork arm
Nut, it is characterised in that：It also includes bearing support and base, and the top of described upper arm is equipped with gear, the axle of gear
The heart is fixed by upper connecting rod, and described bearing support bottom is provided with the bearing support gear track coordinated with gear, bearing support tooth
Wheel track is located between two gears；The bottom of described underarm is equipped with lower gear, and the axle center of lower gear is by lower connection
Bar is fixed, and the base gear track coordinated with lower gear is provided with the top of described base, and base gear track is located under two
Between gear.
Preferably, the top of described upper arm and the bottom of bottom are equipped with hollow space, the axle center of gear and lower tooth
The axle center of wheel is each provided at hollow space.
Preferably, the left end of described screw mandrel is provided with swing handle.
Preferably, the top surface of described bearing support is provided with crisscross anti-slip tank.
The technical scheme provided using the utility model, compared with prior art, is had the advantages that：
The scissor-like jack that the utility model is related to not only goes up the angle of underarm come real in lifting object by changing
Existing, while upper underarm Angulation changes, the lower gear of underarm bottom is rotated with upper underarm Angulation changes, by base
Integrally be lifted up for upper underarm and support frame by base gear track；Meanwhile, gear at the top of upper arm also concomitant rotation drives
Gear track is moved upwards, so that support frame is further lifted, therefore in the case of identical brachium, what the utility model was related to
Scissor-like jack has the characteristics of lifting speed is fast, and extreme higher position is big with the ratio of extreme lower position.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model scissor-like jack.
Mark explanation in schematic diagram：1 upper arm, 2 underarms, 3 left flaps, 4 right flaps, 5 gears, 6 lower gears, 7
Fork arm nut, 8 screw mandrels, 9 bearing supports, 10 bases, 11 bearing support gear tracks, 12 base gear tracks, 13 anti-slip tanks, 14 rotate
Handle, 15 upper connecting rods, 16 lower connecting rods.
Specific embodiment
To further appreciate that content of the present utility model, the utility model is described in detail in conjunction with the embodiments, it is real below
Example is applied for illustrating the utility model, but is not limited to scope of the present utility model.
With reference to shown in accompanying drawing 1, a kind of scissor-like jack that the utility model is related to, it includes two upper arm, 1, two underarms
2nd, left flap 3, right flap 4, fork arm nut 7 and screw mandrel 8, two bottoms of upper arm 1 respectively with left flap 3 and right hinge
Plate 4 is hinged, and two tops of underarm 2 are hinged with left flap 3 and right flap 4 respectively, and fork arm nut 7 is fixed on right flap
On 3, screw mandrel 8 runs through left flap 3 and fork arm nut 7, and the left end of screw mandrel 8 is provided with swing handle 14, is turned by rotation when using
Dynamic handle 14 rotates screw mandrel 8, and the external screw thread on screw mandrel 8 cooperates with the internal thread of fork arm nut 7, makes between underarm
Angle becomes big, plays a part of lifting object.
Two tops of upper arm 1 of above-mentioned scissor-like jack are provided with hollow space, and hollow bulb office is provided with axle center, equal at axle center
Gear 5 is provided with, two axle center of gear 5 are also fixed by upper connecting rod 15, and bearing support 9, institute are provided with the position of gear 5
The bottom of bearing support 9 stated is provided with the bearing support gear track 11 coordinated with gear 5, and bearing support gear track 11 is located on two
Between gear, the top surface of bearing support is provided with crisscross anti-slip tank, to prevent article during lifting article from sliding；Scissor-like jack
The bottom of two underarms 2 is again provided with hollow space, and hollow space also is provided with axle center, and a lower gear 6 is respectively provided with axle center, even
The axle center of individual lower gear is fixed by lower connecting rod 16, and the position of lower gear 6 is provided with base 10, and the top of described base 10 is provided with
The base gear track 12 coordinated with lower gear, base gear track 12 is located between two lower gears.When article is lifted, on
Angle between underarm becomes big, while gear 5 and the concomitant rotation of lower gear 6, lower gear 6 is when base gear track 12 is rotated
The overall motion upwards of underarm in drive, gear 5 will drive support frame 9 to move upwards when bearing support gear track 11 is rotated,
Therefore, in the case of identical brachium and identical screw mandrel velocity of rotation, the jack that the utility model is related to lifts speed with fast, carries
Rise is bigger.
The utility model has been described in detail above in association with embodiment, but the content be only it is of the present utility model compared with
Good embodiment, it is impossible to be considered as limiting practical range of the present utility model.It is all to be made according to present utility model application scope
Impartial change and improvement etc., all should still fall within patent covering scope of the present utility model.
