The driving assembly comprises a handspike, a rotary rod, a thimble and a hook rod, wherein the rotary rod, the thimble and handspike are distributed in the shell in an n shape, one end of the thimble abuts on an air bottle, the other end of the thimble abuts on the side surface of the rotary rod, one end of the handspike is provided with a main spring, one end of the handspike abuts on one end of the main spring, the other end of the handspike abuts on the side surface of the rotary rod, the hook rod is arranged in the shell, a gemel is arranged at the long-edge end of the hook rod and provided with a booster spring at the outer side, the booster spring is parallel to the gemel, and one end of the traction rope is fixedly connected with a middle rotating shaft of the gemel. During the inflation, the rotary rod rotates by using the supporting shaft as a fulcrum to abut on the thimble, the thimble pierces the air bottle under the action of the rotary rod, and the air is released, thus the inflation of the life-saving device is completed so as to activate great power with smaller force.
Description
Technical field
The present invention relates to a kind of trigger mechanism, particularly a kind of trigger mechanism of lifesaving appliance, belong to the technical field of buoyant apparatus.
Background technology
At present, have a kind of water survival to be equipped for the projection-type life-saving equipment, its principle of work is to utilize engine installation or manpower that type inflatable life buoy is projected drowning people's Its Adjacent Waters, then by trigger mechanism, realizes the inflation of buoy quoit, and provides buoyancy for the drowning people.
traditional trigger mechanism, comprise housing, has a breather chamber in housing, the breather chamber outside respectively forms a vigor screw and gives vent to anger screw, to be connected respectively inflation steel cylinder and life saving air bag, and in opposite side, be provided with a drive spindle that can move forward and backward in vent chamber, drive spindle penetrates side and is provided with a spring and a thimble, this thimble is relative with the air inlet screw, and in corresponding drive spindle place, housing top axle, be provided with a pull bar, for when pulling and supporting pull bar, but its convex surface of mat holds drive spindle to be advanced towards the vent chamber thruster, to make this thimble puncture the inflation steel cylinder, thereby realize the inflation to life saving air bag, the gas filled device of this structure, owing to being by people's manual manipulation, when being subjected to drown the person under strenuous status, by manual operations, that in time inflation of life saving air bag is more difficult, therefore, use inconvenient, and safety is poor.
recently, Chinese patent literature discloses a kind of trigger mechanism, the patent name of this trigger mechanism is " meeting the gas filled device that water triggers automatically ", the patent No. is " ZL02241619.6 ", this gas filled device is mainly to be provided with a Brake Block in driven unit, this Brake Block comprises a push rod, in its inserting end, ring suitably forms an oblique clasp face in place, make it to be held in by formed airtight opening after the corresponding concave surface loop bar laminating of two tools, it is to form an anchor ring by a plurality of projections outward, after being folded in this anchor ring upper end for a Compress Spring, and the end face of these two loop bars both sides is respectively tied up admittedly by water-soluble fibre line body, when water enters gas filled device, the water-soluble fibre body dissolves, push rod promotes thimble gas cylinder is exposed, thereby lifesaving appliance is inflated.The shortcoming of this class flip flop equipment is, exposes the required power of gas cylinder very large, and water-soluble fibre line body must bear this power.If water-soluble fibre line body is subject to large like this power for a long time, this water-soluble fibre line body easily is disconnected, thereby causes the misoperation of flip flop equipment, makes the inflation of lifesaving appliance mistake.
In addition,, because this kind trigger mechanism need to could trigger after overboard at device, install the entity state that is still unaerated before overboard, may wound the drowning people in overboard moment, safety is poor.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of trigger mechanism of lifesaving appliance, this trigger mechanism can be in the situation that automatic or remote control, start larger power by less power the opportune moment before device is overboard, the sealing of exposing gas cylinder realizes inflation, guarantees the safety of persons falling in water.In addition, even in the situation that automatic or remote control equipment (RCE) is malfunctioning, this trigger mechanism also can be realized automatic inflating after device is met water.
