Abstract
The utility model discloses a passive ignition mechanism for fire-fighting ejectors. The passive ignition mechanism comprises a handle main body (1) and a trigger (5) movably connected with the handle main body (1). A magneto (2) and a microswitch (3) connected with the magneto (2) are arranged in the handle main body (1). The trigger (5) consists of lugs contacting the magneto (2). The passive ignition mechanism is featured with simple integral structure and small volume and is easy to realize by using the structure, and the security can be increased when the passive ignition mechanism is applied to the fire-fighting ejectors.
Description
Technical field
The utility model relates to the fire extinguishing transmitter, specifically is used for the passive ignition mechanism of fire extinguishing transmitter.
Background technology
Forest fire and miscellaneous cause are very different, in case breaking out of fire in dense forest, the intensity of a fire is rapid spread, thereby can cause irremediable loss.For forest fire is put out a fire, Chinese patent notification number CN 201392142Y has announced a kind of invention and created name and has been the fire-extinguishing apparatus of " Handheld multipurpose forest protection emitter ", this fire-extinguishing apparatus has the advantage such as be easy to carry, mobility is good, efficient is high, but the ignition mechanism complex structure of this fire-extinguishing apparatus, this has just increased the cost of this fire-extinguishing apparatus, and this fire-extinguishing apparatus adopts dry cell class DC power supply, have power supply in the fire-extinguishing apparatus, just there is larger potential safety hazard in this always.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, and can improve the passive ignition mechanism that is used for the fire extinguishing transmitter of peaceful property when being applied on the forest protection transmitter.
The purpose of this utility model is achieved through the following technical solutions: the passive ignition mechanism that is used for the fire extinguishing transmitter, comprise handgrip body and the trigger that is flexibly connected with the handgrip body, the microswitch that is provided with magneto in the described handgrip body and is connected with magneto, described trigger consists of the projection that contacts with magneto.When the utility model is applied on the gloomy protection launcher, magneto and microswitch all are electrically connected the sparking contact of transmitter electric firing breech, wherein, two connecting lines that are connected with magneto are connected with sparking contact with microswitch respectively, firing circuit loop of the whole formation of the sparking contact of magneto, microswitch and electric firing breech.
Be provided with safety plug in the described handgrip body, described trigger consists of the projection that contacts with safety plug.Wherein, safety plug is used for trigger is carried out spacing, and the utility model just opens safety plug when using, and this further improves security of the present utility model.
Be used for the passive ignition mechanism of fire extinguishing transmitter, also comprise torsion spring, the two ends of described torsion spring act on respectively handgrip body and trigger.Torsion spring gives trigger certain active force all the time in the utility model, returns to original state having detained under the active force of trigger rear trigger at torsion spring, and then pulls the trigger ready for cocking next time.
Compared with prior art, the utlity model has following beneficial effect: the utility model comprises handgrip body and the trigger that is flexibly connected with the handgrip body, wherein, the microswitch that is provided with magneto in the handgrip body and is connected with magneto, trigger consists of the projection that contacts with magneto, the utility model overall structure is simple, be convenient to realize, volume is little, the life-span of magneto is long than dry cell, the utility model adopts magneto to substitute the dry cell class dc source that has now in the fire-extinguishing apparatus, not only reduced the wasting of resources that battery brings but also the effect of having played environmental protection used, when using, the utility model needs cocking bump magneto ability generation current, when being applied on the forest protection transmitter, the utility model can avoid existing fire-extinguishing apparatus dry cell to be housed and the existing potential safety hazard of power supply is arranged always, thereby improved security, easy to utilize.
Description of drawings
Fig. 1 is the structural representation behind the utility model embodiment broken section.
The corresponding name of Reference numeral is called in the accompanying drawing: 1, handgrip body, 2, magneto, 3, microswitch, 4, safety plug, 5, trigger, 6, torsion spring.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing, but embodiment of the present utility model is not limited to this.
Embodiment:
As shown in Figure 1, the passive ignition mechanism that is used for the fire extinguishing transmitter, comprise handgrip body 1 and trigger 5, wherein, handgrip body 1 adopts the cast aluminium manufacturing, trigger 5 is flexibly connected with handgrip body 1, the microswitch 3 that is provided with magneto 2 in the handgrip body 1 and is connected with magneto 2, magneto 2 and microswitch 3 all are electrically connected the sparking contact of transmitter electric firing breech, wherein, two connecting lines that are connected with magneto 2 are connected with sparking contact with microswitch 3 respectively, firing circuit loop of the whole formation of the sparking contact of magneto 2, microswitch 3 and electric firing breech.The quantity of microswitch 3 is one, by a microswitch 3 is set the volume in handgrip body 1 accommodating magneto 2 and microswitch 3 spaces is reduced, and then can reduce the volume of handgrip body 1.For the ease of trigger 5 control magnetos 2 generation currents, trigger 5 consists of the projection that contacts with magneto 2, and trigger 5 bump magnetos 2 make magneto 2 generation currents when cocking 5, and then transmitter is got angry.
For trigger 5 is positioned, be provided with safety plug 4 in the handgrip body 1, trigger 5 consists of the projection that contacts with safety plug 4.For cocking 5 rear triggers 5 are automatically reset, be connected with torsion spring 6 between handgrip body 1 and the trigger 5.
When being used for the passive ignition mechanism work of fire extinguishing transmitter, opening safety plug 4 does not contact it with trigger 5, the shift knob of microswitch 3 is opened, for the connection of circuit ready, press simultaneously magneto 2 and make magneto 2 energy storage, cocking 5 makes its bump magneto 2 again, and magneto 2 generation currents are got angry transmitter, and then finishes the emission of shell.
As mentioned above, then can well realize the utility model.
