Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of hydraulic pressure adjustable wrench adopting hydraulic cylinder to regulate openings of sizes is provided, time oil-filled to hydraulic cylinder, opening is turned down, effect opening by spring when draining the oil is tuned up, easy to adjust and there will not be due to leading screw locking cause the jammed situation of spanner.
For achieving the above object, the utility model adopts following technical proposals:
A kind of hydraulic pressure adjustable wrench, comprise mechanical part and hydraulic system, described mechanical part comprises wrench body, and described wrench body front end is provided with regular jaw and moving jaw; Described hydraulic system comprises shoe cream room, performs oil cylinder and oil-filled oil cylinder, described shoe cream room is located at wrench body inside, shoe cream room is communicated with oil-filled oil cylinder by the first pipeline, oil-filled oil cylinder performs oil cylinder by the second pipeline connection, described execution oil cylinder is arranged on the regular jaw place of wrench body, and be connected with moving jaw, the rear end of wrench body is located at by described oil-filled oil cylinder, is also connected with gate gurgle valve between described first pipeline and the second pipeline.
The hinged oil-filled handle in described wrench body rear end, oil-filled handle is connected with oil-filled oil cylinder by connecting rod.
Described first pipeline is provided with the first check valve, and described second pipeline is provided with the second check valve.
The junction of described gate gurgle valve and the first pipeline is between the first check valve and shoe cream room, and the junction of described gate gurgle valve and the second pipeline is at the second check valve and perform between oil cylinder.
Described wrench body is provided with draining button with corresponding section, gate gurgle valve position, and draining button is connected with gate gurgle valve.
Be equipped with spring in described execution oil cylinder, shoe cream room and oil-filled oil cylinder, there is self-return function.
In described execution oil cylinder, the elastic force of spring is greater than the elastic force of spring in shoe cream room.
The in-oil cylinder piston diameter of described execution is greater than oil-filled in-oil cylinder piston diameter.
When the utility model hydraulic pressure adjustable wrench uses, realize performing oil cylinder by the oil-filled handle repeatedly pinching wrench body rear portion oil-filled, reduce its overhang, drive moving jaw, reduce the opening of adjustable wrench.When needs increase wrench opening size time, press the gate gurgle valve on wrench body, under the effect performing oil cylinder contained spring, increase its overhang, drive moving jaw to increase the opening size of spanner.
The beneficial effects of the utility model are:
Hydraulic pressure adjustable wrench of the present utility model regulates the size of wrench opening size by hydraulic control oil cylinder, easy to use, and can avoid, because leading screw locking causes spanner to snap into phenomenon on bolt, effectively can improving the operating efficiency of user.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in figs 1 to 6, hydraulic pressure adjustable wrench is made up of mechanical part and hydraulic system.
Mechanical part mainly comprises wrench body 1, regular jaw 2, moving jaw 3, and oil-filled handle 4, draining button 5 forms.
Hydraulic system mainly comprises shoe cream room 6, and perform oil cylinder 7, check valve a8, check valve b9, gate gurgle valve 10, oil-filled oil cylinder 11 forms.
The each parts of hydraulic pressure and oil circuit are integrated in mechanical part, wherein: perform oil cylinder 7 and be connected with moving jaw 3, control its motion; Oil-filled oil cylinder 11 is connected with oil-filled handle 4, can be execution oil cylinder 7 oil-filled; Draining button 5 is connected with gate gurgle valve 10.
Gate gurgle valve 10 is a button form, is installed in the middle part of wrench body 1, presses the button beginning draining, and opening increases, release button, button self-return, stops draining, and opening stops increasing.
The piston diameter performing oil cylinder 7 is greater than the piston diameter of oil-filled oil cylinder 11.Perform in oil cylinder 7, oil-filled oil cylinder 11 and shoe cream room 6 and all spring is housed, there is the function of self-return, and perform the elastic force of elastic force much larger than shoe cream room 6 inner spring of oil cylinder 7 inner spring.
During use, when wrench opening size turned down by needs, as long as repeatedly by pinching oil-filled handle 4, due to the effect of check valve 8,9, the hydraulic oil in shoe cream room 5 being charged to and performing in oil cylinder 7, thus drive moving jaw 3 to reduce wrench opening size.When needs tune up wrench opening size, only need press draining button 5, drive gate gurgle valve 10 will perform oil cylinder 7 and shoe cream room 6 UNICOM, perform oil cylinder 7 draining, drive moving jaw 3 to increase wrench opening size.
