Abstract:
1. A safety structure of a gas burner, comprising: a slide, said slide having a frame base accommodating a first spring means, a key from said frame base, two upright rods arranged in parallel at a top side of said frame base, a guide way defined between said upright rods, two transverse retaining grooves respectively formed on said upright rods at an inner side, and a pair of guide ribs respectively transversely provided at said upright rods at a bottom side; a stop device received in said sliding way of said slide, said stop device having a stop plate, a finger strip forwardly extending from said stop plate, a guide strip and a pin backwardly extending from said stop plate, two retaining blocks respectively extended from left and right sides of said stop plate for engaging the retaining grooves of said slide to lock said slide, two recessed portions respectively defined between the stop plate and the retaining blocks, and a third spring means mounted on said pin; and a housing formed of two cover shells, said housing having a longitudinal sliding slot and a guide way for the passing of said key and said finger strip respectively, a frame wall transversely disposed below said guide way and stopped against said third spring means, and a sliding slot cut through said frame wall for the passing of said guide strip; wherein when the user presses said slide, said third spring will be compressed to lower said stop device and to further disengage said retaining blocks from said retaining grooves, thereby releasing said stop device from the constraint of said slide; when the user keeps pressing said slide at this time, said retaining blocks will be moved to a bottom side of said guide ribs and said frame base will be forced to squeeze said first spring means to release the locked state.
