Background technology
Petrol service station all adopts the self-sealing nozzle during to automobile fuel filler, and this nozzle has the function that can close automatically when the fuel tank of automobile is filled it up with oil.Be the self-sealing nozzle of ZL 200820121082.5 as the patent No., comprise the rifle body, Handleset, main valve, control cock, oil outlet pipe, main valve is by main valve plug, main valve seat, piston bush, piston is formed, convex shoulder outside the end of piston bush and main valve plug junction is shaped on, be somebody's turn to do between outer convex shoulder and the gun rack and be provided with the piston bush spring, piston places in the piston bush, its end near main valve plug one end is shaped on convex shoulder, in this convex shoulder and piston bush, be provided with piston spring between the step, the other end is hinged by handle driving lever and Handleset, is shaped on groove at piston bush and middle of piston, captive joint one locating rack on the diaphragm unit of control cock, when fueling state, roller on the locating rack inserts in the groove of piston bush and piston, and when filling it up with oil, locating rack is raised, automatically close main valve, realize self-styled function.Its major defect is: an end of handle driving lever and an end of handle are hinged, and an end of the other end and the axis of the piston is hinged, and its hinge-point is on the line of centers of the axis of the piston, the length that handle is opened the arm of force is two distances between the hinge-point, the arm of force is long, and moment is big, opens heavy.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, provide a kind of unlatching moment little, operate the self-styled nozzle of hand-held design easily.
The technical solution of the utility model comprises rifle body, Handleset, main valve, control cock, oil outlet pipe, be shaped on oil inlet passage in the rifle body, main valve is installed in the oil inlet passage, be provided with control mechanism between main valve and control cock, this control mechanism is made up of automatic control axle, axle sleeve, axle sleeve spring and automatic control axle spring; The oil outlet pipe leading section is shaped on pore self-sealing, and this pore self-sealing is communicated with the controlling diaphragm chamber of control cock by self-styled passage, and Handleset is connected with the automatic control axle by the handle driving lever; An end that mainly is the handle driving lever is connected with an end of automatic control axle by contiguous block, this contiguous block is fixedly mounted on the end of automatic control axle, constitute downward radially convex shoulder between contiguous block and the automatic control axle periphery, the end periphery of handle driving lever is in contact with one another with the convex shoulder of contiguous block and is connected.
Preferably, main valve is made up of valve seat and spool, valve seat is fixedly mounted in the oil inlet passage of rifle body, connect an orienting sleeve on the valve seat inner round wall, the orienting sleeve periphery is captiveed joint with valve seat by dowel, the orienting sleeve endoporus is connected with the pilot bar running-fit, and pilot bar one end is connected with the center fixation of spool.
The utility model beneficial effect compared with prior art is: an end of handle driving lever is connected with an end of automatic control axle by contiguous block, make the hinge-point between handle driving lever and the automatic control axle be in automatic control axle downside, shortened the unlatching arm of force, reduced and open moment, had and open advantages such as light.
