Description
Technical field
It the utility model is related to a kind of hydraulic means, and in particular to there is the lifting body of function of increasing pressure.
Background technology
Jack is a kind of highly small simplest crane gear of lifting, by the use of rigidity top lift part as equipment, is led to
Cross top bracket or bottom claw jacks the light small crane gear of weight in stroke.Jack is divided into mechanic jacks and hydraulic pressure
Two kinds of jack, principle is had nothing in common with each other.For from principle, hydraulic jack the principle on which is pascal's principle, i.e.,：Liquid
The pressure of body everywhere is consistent, and so, in the system of balance, the pressure that smaller piston upper applies is smaller, and
The pressure applied on big piston is also bigger, can so keep the static of liquid.So by the transmission of liquid, can obtain
Different pressure on to different ends, it can thus reach the purpose of a conversion.Mechanic jacks use theory of mechanics, with
Reciprocal to pull handle, pusher dog promotes the revolution of ratchet gap, and cone pinion drives large bevel gear, rotates weight lifting screw rod, so as to
Jacking sleeve is obtained raising or decline, and reach the function of lifting pulling force.But mechanic jacks are simple not as hydraulic jack.
Wherein, hydraulic jack is also known as hydraulic jack, be it is a kind of using plunger or hydraulic cylinder as rigid top lift part
Jack.Hydraulic jack is compact-sized, stable working, has a self-locking action, therefore uses extensive.Its shortcoming is that lifting highly has

Bar handle, the problem of causing further increase the lifting force of jack.The utility model is the base in Pascal's law
The innovation and creation made on plinth.Pascal's law is a fluidstatic law, Pascal's size unchangeably from liquid to
All directions transmission.The size of pressure is according to static pressure fundamental equation：P=p0+ ρ gh draw, p0For additional pressure, ρ gh are original
The pressure come, p are pressure total after changing.For example the liquid in closed container is contained in, the pressure of itself is ρ gh, outside it
Pressurize strong p0When changing, as long as liquid still keeps the inactive state of its original constant, the pressure of any point will in liquid
An equal amount of change of generation.In other words, in closed container, the pressure that puts on inactive liquid will be with equivalent while pass
To each point, i.e. p=p0+ρgh.Here it is pascal's principle, or Hydrostatic Transfer Device principle.
