Summary of the invention
The purpose of this utility model is to provide a kind of gas generator to pull the trigger starter gear, make up the deficiencies in the prior art, combine the advantage of knob and push button, be rotary motion the pressing conversion of motion of longitudinal direction, only need less pressure just can start, possess simple, quick, safe and reliable advantage.
The technical solution of the utility model is: housing has more than one limit guide groove, striker bottom is provided with more than one position-limited lever corresponding with limit guide groove, striker is pressed into housing cavity after inserting firing pin spring, the position-limited lever of striker is installed in the limit guide groove of housing, outside is set with the press device rotated for promoting striker, and safety plug is plugged on press device, housing, striker.Safety plug can stop longitudinal movement and the rotary motion of percussion lock.
Described press device comprise pressure cap, offset with pressure cap instead push away spring, pressure cap lower end has more than one wedge type groove, and wedge type groove is corresponding with position-limited trough.
The axial groove that described limit guide groove is connected with radial slot by radial slot forms, and the arc length at notch place, wedge type groove lower end is greater than the radial slot arc length of limit guide groove.
Described limit guide groove is two, and two limit guide grooves distribute axisymmetricly; Wedge type groove is two, and two wedge type grooves distribute axisymmetricly; Position-limited lever is two.
Described housing is stepped appearance, the large stage portion comprise superposed small stair portion, being connected with small stair portion, instead pushes away the small stair portion that spring housing is loaded on housing.
Described housing upper end is provided with baffle plate, and pressure cap inwall is provided with the flange matched with baffle plate, instead pushes away spring upper end and flange offsets.Baffle plate step stops pressure cap endoporus flange.
Described housing upper end is threaded with baffle plate.
Described pressure cap threaded upper ends is connected with plug.
In the middle part of described pressure cap, housing central section, striker top is equipped with mounting hole for plug-in mounting safety plug.
Described housing exterior walls is provided with guided way, and pressure cap inwall is provided with guide groove; Or housing exterior walls is provided with guide groove, pressure cap inwall is provided with guided way, prevents relatively rotating of pressure cap and housing.
The beneficial effects of the utility model are as follows: 1, in conjunction with push button and knob advantage, only select pressing promotion striker gently to rotate to an angle and striker can be made to tell motion percussion primer realization igniting, ensure that the reliability that producer is lighted a fire after extracting safety plug.2, arrange guided way and guide groove and prevent relatively rotating of pressure cap and housing, guided way also can the rotation of anti-block candle end box.3, safety plug has the effect preventing pressure cap longitudinal movement and striker rotary motion, ensure that the safety of shipping storage.It is simple that the utility model has structure, and cost is low, and reliability is high, advantage simple to operate.
