Abstract

An ignition gun with an insurance device comprises a gun pipe (1), a gun body (2) an ignition button (3), an insurance button (4) that is arranged on one side of the of the position that the ignition button (3) is relative to the ignition button (3), a hook portion (4) that projects outwards is arranged on the lower end of the insurance button (4), and a spring (5) that is arranged in the gun body (2). In natural state, the spring (5) forces the lower end hook portion (43) stretch inwards, which causes the rear portion of the ignition button (3) retained by the lower end hook portion (43) rightly. When igniting, the upper end of the insurance button must be pushed downwards and held on, which causes the lower end portion leave the step of the ignition button, so the ignition button can be smoothly pushed downwards and ignites. Because the finger force of toddler is limited, even they know how to ignite but they are without force to push the insurance button downwards and ignite.

Description

A kind of burning torch with safeties

The utility model relates to a kind of burning torch, particularly a kind of burning torch with safeties.

At present, match withdraws from average family substantially, the substitute is lighter and burning torch, and wherein burning torch is mainly used to light the gas-cooker of non-electronic ignition, also is used for sometimes at picnic time point combustion bonfire.Existing burning torch is provided with a gas storage box and a spark generating mechanism, when pressing button ignition switch generally by gun barrel, rifle body and button ignition switch in the rifle body, the gas outlet of gas storage box is opened, combustion gas is overflowed from the gun barrel mouth, and this moment, the spark generating mechanism sent spark simultaneously, and combustion gas is lighted; General button ignition switch all can automatically reset, and after it resetted, the gas outlet of gas storage box was sealed automatically again, and the spark generating mechanism also automatically resets simultaneously.For preventing false triggering, existing burning torch generally also is provided with a locking mechanism at button ignition switch, promptly when it is in latched position, button ignition switch can't be pressed because of being stopped by it, yet the locking mechanism of existing burning torch all is can not be automatically reset, and under the general situation, the user is set in unlock state with this locking mechanism mostly for following the line of least resistance.This just brings a potential safety hazard: just because of burning torch operation is very simple, so just very likely its false triggering is lighted a fire when having the child to play burning torch among the manager, thereby might hurt the child, and also might be therefore and initiation fire.Show, a considerable amount of these class accidents are arranged really at home and abroad every year according to relevant statistics.

The purpose of this utility model just is that providing a kind of provides a kind of burning torch that can prevent the band safeties of child's mis-ignition to a certain extent at above-mentioned prior art present situation.

Design of the present utility model is: the burning torch of band safeties comprises gun barrel, rifle body and button ignition switch, it is characterized in that being provided with a stop button in a side of the relative button ignition switch of rifle body, there is the hook portion of an evagination lower end of stop button, one spring is arranged in the rifle body, under nature, this spring forces the lower end hook portion of stop button inwardly to be stretched, and the rear portion of described button ignition switch is just in time stopped by described stop button lower end hook portion.

Described spring should have certain coefficient of stiffiness, and its standard can't be pressed for making the child just, and for adult unlikely too much like hard work;

Described spring is good with torsion spring, and this moment, stop button middle part can be provided with a bearing pin, torsion spring set thereon, the one end is spacing on housing, the spacing bottom at stop button of the other end;

Described button ignition switch is good to be provided with a step with the lower end hook portion that cooperates described stop button at the rear portion.

Compared with prior art, when igniting, must press the stop button upper end earlier and not put, the lower end hook portion of stop button is left the step of button ignition switch at this moment, so button ignition switch can be pressed smoothly and light a fire.Because child's finger power is limited, can select suitable torsion spring to make it can't press stop button, even it knows the also unable igniting of how lighting a fire like this, so the utility model to lean on various complex mechanisms to baffle child's design than those safer.

Description of drawings:

Fig. 1 is the sectional perspective structural representation (wherein a side body takes off) of the utility model embodiment.

Fig. 2 is the stereogram of button ignition switch among Fig. 1.

Fig. 3 is the stereogram of stop button and torsion spring thereof among Fig. 1.

Fig. 4 is the side view (wherein a side body takes off) of nature.

Fig. 5 is the side view (wherein a side body takes off) of fired state.

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Shown in Fig. 1～5, the burning torch of band safeties comprises gun barrel 1, rifle body 2 and button ignition switch 3, be provided with a piezoelectricity device 6 under the button ignition switch 3, the bottom of rifle body 2 also is provided with the gas storage box (not shown), and wherein piezoelectricity device 4 is used for producing voltage and causes the discharge spark (not shown) by lead at the gun barrel mouth;

Side at rifle body 2 relative button ignition switches 3 is provided with a stop button 4, there is the hook portion 43 of an evagination lower end of stop button 4, stop button 4 middle parts are provided with a bearing pin 41, be with stop button 4 integrated through injection molding in the present embodiment, one torsion spring 5 is enclosed within on this bearing pin 41, one end 51 of torsion spring is against with housing 2 and is connected on the limited post that replaces 21, and the other end 52 is against on the projection 42 that is fixed with one with stop button 4, thereby forces the lower end hook portion 43 of stop button inwardly to be stretched;

The rear portion of described button ignition switch 3 is provided with a step 31 in relative hook portion 43 positions, stop button lower end, and under nature, the stop button lower end hook portion 43 that this step 31 is just in time inwardly stretched out stops.

Described torsion spring 5 is not limited to the set-up mode of present embodiment, even also is not limited to the torsion spring form, can be stage clip, extension spring or reed, as long as it forces the lower end hook portion 43 of stop button inwardly to be stretched, concrete scheme can adopt prior art, does not describe in detail.

During igniting, must press stop button 4 upper ends earlier and not put, make the lower end hook portion 43 of stop button leave the step 31 of button ignition switch, this moment, button ignition switch 3 no longer was subjected to stopping of stop button 4, therefore can be pressed smoothly and lighted a fire.
