Description
Technical field
The present invention relates to mechanical field, more particularly to a kind of jack against 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.It is divided to mechanical and two kinds of fluid pressure type, it is very heavy
Top is mainly used in the departments such as factories and miness, communications and transportation as the work such as Mechanical Help and other liftings, support.Its light structure is hard
Gu, flexibility and reliability, a people can carry and operate.Jack employs optimum as a kind of extensive instrument of use range
Cast, ensure that the quality and service life of jack, jack is divided into two kinds of mechanic jacks and hydraulic 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.,：The pressure of liquid everywhere
It is consistent by force, so, in the system of balance, the pressure that smaller piston upper applies is smaller, and on big piston
The pressure of application is also bigger, can so keep the static of liquid.So by the transmission of liquid, can obtain on different ends
Different pressure, can thus reach one conversion purpose.We it is common to hydraulic jack be exactly that make use of
This principle reaches the transmission of power.Mechanic jacks use theory of mechanics, and back and forth to pull handle, pusher dog is promoted between ratchet
Gap is turned round, and cone pinion drives large bevel gear, rotates weight lifting screw rod, so that jacking sleeve obtains raising or decline, and reaches
To the function of lifting pulling force.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of weight for being capable of real-time display jack stand, prevent from pushing up
Lifting capacity exceedes the jack against pressure of jack load-bearing, to solve caused above-mentioned multinomial defect in the prior art.
To achieve the above object, the present invention provides following technical scheme：A kind of jack against pressure, pressure sensor, liter
Sleeve, nut, thrust bearing, rocking bar, gear, square toes flat key, round end flat key, screw rod, housing, base and display screen composition drop,
Screw rod is inserted into housing, and round end flat key is arranged on screw rod, and square toes flat key is enclosed on outside screw rod, and round end flat key is set with square toes flat key
Some shaggy tooths are mutually twisted, and gear is arranged on the right side of square toes flat key, and thrust bearing is arranged on the top of screw rod, and rocking bar is horizontal
Insert in thrust bearing, thrust bearing is inserted into jacking sleeve, and pressure sensor is arranged on the top inside jacking sleeve, is led to
Cross the nut being arranged on the right side of jacking sleeve to fix, base is arranged on the bottom of housing, and display screen is arranged on housing.
Preferably, the rocking bar is provided with handle.
Preferably, the display screen, it is made up of housing, screen, operating key, on ＆ off switch, warning lamp and buzzer, screen is set
Put and be arranged in housing upper semisection, operating key on housing, below screen, on ＆ off switch is arranged on the side of housing, warning lamp
The upper right side of housing is arranged on, buzzer is arranged on the upper left side of housing.
Beneficial effect using above technical scheme is：Such weight for being designed to real-time display jack stand,
Prevent that jacking up weight exceedes jack load-bearing；Rubber buffer pad is installed at the top of jacking sleeve, it is such to be designed to
To the protective effect to jack, in order to avoid the overweight infringement jack of weight；Square toes flat key is provided with polytetrafluorethylecoatings coatings, this painting
The wear-resisting anti-scratch of layer, the coefficient of friction on surface is small, can play a part of smooth square toes flat key and be slided with round end flat key；Rocking bar is provided with
Handle, when operating jack, only need shake handle that lifting jack can be achieved, facilitate the operation of user；Display screen,
It is made up of housing, screen, operating key, on ＆ off switch, warning lamp and buzzer, screen is arranged on housing upper semisection, and operating key is set
On housing, below screen, on ＆ off switch is arranged on the side of housing, and warning lamp is arranged on the upper right side of housing, buzzer
The upper left side of housing is arranged on, the threshold value of jack pressure can be set by operating key, when pressure exceedes the threshold value
Warning lamp flashes, and buzzer alarm sounds sound plays warning function, prevents the excessive infringement jack of pressure.
