Description
The utility model relates to a kind of portable manual instrument of rescuing usefulness.
When major traffic accidents or fire take place when, people often use a kind of portable hand hydrodynamic pressure orcible entry rescue cutting nippers that car door or antitheft door are pried open, or cut off door and window and protect and block, so that rapidly driver and conductor in the car or indoor trapped personnel are saved out or rescue property, reduce the loss.The rescue cutting nippers of people's use at present can be cut off the rod iron of diameter 20mm or the steel plate of thick 10mm.Known rescue cutting nippers mainly is made up of cutting nippers head and cutting nippers body two parts.The cutting nippers head is made up of a pair of cutting nippers cutter and pair of links.The cutting nippers head is used to cut off or strut object, the hydraulic system of being made up of hydraulic cylinder, rotary three-position four-way valve, two position three-way valve, hand pump, safety valve, check valve, fuel tank assembly etc. is housed in the cutting nippers body, the cutting nippers head drags its folding and unfolding by hydraulic cylinder, carries out and cuts off or strut task.The fuel tank assembly of the hydraulic system of this known rescue cutting nippers is installed in the back of hydraulic cylinder and is positioned on the same axis.Because the hydraulic pressure runner in the cutting nippers body is tiny, complicated, fabrication hole is stifled a lot of, the fuel tank volume is little in addition, in order to overcome the oil suction deficiency, is provided with a flexible rubber dissepiment in the fuel tank of fuel tank assembly, connects a creosoted pole on the diaphragm of rubber.During oil suction, diaphragm of rubber is out of shape under the atmospheric pressure effect makes the fuel tank smaller volume; When pressing oil, diaphragm of rubber reversal deformation under the oil pressure effect makes the fuel tank volume become big.When pouring into hydraulic oil to the hydraulic system of hydraulic pressure rescue cutting nippers, people at first dismantle cutting nippers rotary three-position four-way valve on one's body, and the cutting nippers body is upwards erect, then to wherein irritating oil.When irritating oil, continuous push-and-pull creosoted pole to drive the diaphragm of rubber distortion and the fuel tank volume is increased or dwindle, thus make fuel tank suck fluid and discharge fuel tank and runner in air.Because the diaphragm of rubber deflection is limited, fill with side by side that net air generally need spend nearly four hours time, not only time-consuming but also trouble, and also rubber membrane is easily aging, the life-span is short, diaphragm of rubber is to vulcanize on the short and small cylindrical wall of fuel tank in addition, installs and changes trouble, cost height.
The purpose of this utility model is to overcome above-mentioned shortcoming, provide a kind of simple in structure, long service life, installation and maintenance change convenient, cost is low, the hand-hydraulic orcible entry rescue cutting nippers of the hydraulic oil that is easy to annotate.
The utility model hand-hydraulic orcible entry rescue cutting nippers, comprise the hydraulic system that is used to drive the cutting nippers head that is installed in the cutting nippers body, the fuel tank assembly of described hydraulic system is positioned at the back of hydraulic cylinder, the piston of the band piston rod that sealing ring is housed on its that matches with inner wall of oil tank is housed in the fuel tank of described fuel tank assembly, described piston rod is provided with air inlet/outlet, its tail end is provided with connecting thread, between the handle of described piston rod and described cutting nippers body the recovery spring is housed.
The utility model hand-hydraulic orcible entry rescue cutting nippers, the connecting thread of wherein said piston rod tail end is an internal thread.
The utility model hand-hydraulic orcible entry rescue cutting nippers wherein is equipped with the air filtration part between the handle endoporus of the tail end of described recovery spring and described cutting nippers body.
The utility model hand-hydraulic orcible entry rescue cutting nippers is simple in structure, easy disassembling, installation and maintenance convenience, low cost of manufacture, long service life.When in the rescue pincers, irritating oil, pull bar push-and-pull piston back and forth can be installed on piston rod, because of piston can move to the other end from an end, stroke is longer, so only need come and go push-and-pull when irritating oil several times just can be with the air emptying injecting oil liquid in the hydraulic system, perfusion is easy, efficient is high, can fill fluid in general about 10 minutes.
Other details of the utility model hand-hydraulic orcible entry rescue cutting nippers and characteristics can be cheer and bright by reading the embodiment that hereinafter encyclopaedizes in conjunction with the accompanying drawings, wherein:
Fig. 1 is the utility model hand-hydraulic orcible entry rescue cutting nippers structural principle schematic diagram.
With reference to Fig. 1.The utility model hand-hydraulic orcible entry rescue cutting nippers is made up of cutting nippers head 1 and cutting nippers body 2.Cutting nippers head 1 is made up of a pair of cutting nippers cutter 3 and pair of links 4.The hydraulic system of being made up of hand pump 5, two position three-way valve 6, rotary three-position four-way valve 7, hydraulic cylinder 8, fuel tank assembly 9, safety valve 10, check valve 11,12,13 is housed in the cutting nippers body 2, this hydraulic system and known rescue cutting nippers are basic identical, and its difference is the fuel tank assembly 9 of hydraulic system.Fuel tank assembly 9 is to be screwed the back that is installed in hydraulic cylinder 8, constitutes the part of cutting nippers body 2.The piston 16 of band piston rod 15 is housed in the fuel tank 14 of fuel tank assembly 9, sealing ring 17 is housed on the piston 16.Form movingly between piston 16 and the fuel tank 14.The tail end that piston rod 15 is provided with air inlet/outlet 18, piston rod 15 is processed with internal thread 19, when giving the hydraulic system oiling, is used to connect external pull bar.Obviously, the tail end of piston rod 15 also can be made into external screw thread, can external joint sleeve during use.Between the endoporus of the handle 20 of piston rod 15 and cutting nippers body 2, be equipped with and recover spring 21, between the endoporus of tail end that recovers spring 21 and handle 20, air filtration pieces 22 is housed.
During the oiling of the utility model hand-hydraulic orcible entry rescue cutting nippers, the same with known hand-hydraulic orcible entry rescue cutting nippers, need at first dismantle rotary three-position four-way valve 7 and handle 20, and on piston rod 15, connect an external pull bar, to rescue cutting nippers and place vertically upside down, toward the interior filling of the valve opening hydraulic oil of three-position four-way valve 7.Meanwhile, reciprocating sliding piston 16, make it move to the other end from an end, to reach the purpose of the air in abundant oil suction and the discharge hydraulic system, come and go push-and-pull several times like this, about about 10 minutes time can be loaded onto three-position four-way valve 7, spring 21, filter 22 and handle 20 then with whole hydraulic system injecting oil liquid, can use.
The utility model hand-hydraulic orcible entry rescue cutting nippers using method is identical with known orcible entry rescue cutting nippers with the course of work, and for avoiding loaded down with trivial details, this paper repeats no more.
