Description
Technical field
The utility model relates to weight-lifting equipment technical field, especially relates to a kind of foot-operated jack for vehicles.
Background technology
Jack is a kind of weight-lifting equipment, in various fields, has multi-form jack.Car jack is that we are the most familiar a kind of, and car jack is the service tools of automobile indispensability, and the vehicle body of jack-uping, is convenient to changing of tire.The kind of car jack can be divided into five kinds of rack-jack, lifting screw, scissor-like jack, hydraulic jack and Inflated jacks.
Rack-jack: it is comprised of tooth bar, gear, handle portion respectively, thus it relies on swinging handle arm revolving gear to make tooth bar rise and fall, and this is also the kind of the common a kind of car jack of general-utility car.Its volume is little, relatively good depositing.But also just because of this, having limited its supported weight can not be too large.
Hydraulic jack: by manpower or driven by power Hydraulic Pump, by hydraulic efficiency pressure system transmission, lift part with cylinder body or piston as top.Its operating ambient temperature is subzero 20 degrees Celsius to 45 degrees Celsius above freezing.Hydraulic jack can be divided into integral type and separation type.All-in-one-piece pump and hydraulic actuating cylinder join together; Hydraulic jack compact conformation, energy is jacking weight steadily, and driving efficiency is higher, therefore application is wider; The pump of separation type is separated with hydraulic actuating cylinder, middle connected with high pressure hose.But easy oil leakage, should not support weight for a long time.
Lifting screw: lifting screw claims again mechanical jack, by manpower, by screw pair transmission, screw rod or ut socket are lifted part as top.Common lifting screw is supported weight by screw thread self-locking effect, simple structure, but driving efficiency is low, and return is slow.From the screw thread that falls lifting screw, without self-locking action, drg is housed.Loosen the brake device, weight is fast-descending voluntarily, shorten return trip time, but this jack structure is more complicated.
Scissor-like jack: scissor-like jack is can promote the geometrical principle making of high line and come based on the equicrural triangle constant shortening of two waists base.It regulates the base of upper and lower two isoceles triangles to promote and falling head by screw mandrel and nut.The weight of the special tectonic jack-up based on scissor-like jack is not too large, and safety is not high.
Inflated jack: the kind of this car jack is uncommon.It relies on tail gas to its inflation, jack-up automobile.Therefore usage condition is more special and rarely known by the people.This jack is the in the situation that of car engine, to use, and during car engine, danger is larger.
At present at auto trade, using maximum is hydraulic jack and scissor-like jack, and their something in common is all the arm driving work that utilizes people, and in some cases, operator carries out work under need to arriving car, greatly dangerous; In heavy lift situation, the mode fatigue strength driving with arm is high, and operator's arm is easy to fatigue.
Summary of the invention
