Abstract

The utility model relates to an electronic igniting gun of gas, natural gas, etc. The middle part of an existing electronic igniting gun is added with an automatic safety device. The automatic safety device is composed of a safety pressure rod, a safety button, an elastic body and a safety spacing part. The elastic body enables an ignition trigger to be locked by the safety spacing part under a safe state, and thus the igniting gun can not be used. Because the utility model is provided with the automatic safety device, thus the safety coefficient of the electronic igniting gun is enhanced, and the defects of poor reliability and inconvenience of an electronic igniting gun at present are solved.

Description

The burning torch that has automatic safety

The utility model relates to the electronic ignition rifle of inflammable gases such as a kind of coal gas, natural gas, particularly be a kind of electronic ignition rifle that has safeties.

Electronic ignition rifle tool safeties on the domestic and international market only have one to be contained in the lip-deep discharge cock of rifle shell at present, be marked with " ON ", " OFF " two positions at the rifle shell, stir discharge cock to " OFF " position with finger, discharge cock has limited moving of button, must stir discharge cock to " OFF " position after each the use, just can play safety effect, use extremely inconvenient, safety coefficient is low, and poor reliability can not prevent the peril of playing and bringing because of child.

The purpose of this utility model provides a kind of electronic ignition rifle that has automatic safety, and it has overcome existing electronic ignition rifle safeties and has used the shortcoming inconvenient, that safety coefficient is low.

Design of the present utility model is to add an automatic safety at existing ordinary electronic burning torch middle part.Automatic safety is made up of insurance depression bar, safety button, elastomer and insurance stop portion.Safety button is through in the circular hole on the electronic ignition rifle shell on the top of insurance depression bar.Insurance has an elastomer on the depression bar, and elastomeric effect is, its elastic force steering handle insurance depression bar is upwards pressed, and makes the circular hole of safety button from shell to extrapolation, stretches out in shell.Also have an insurance stop portion on the insurance depression bar, it is corresponding with the trigger positive stop end on the burning torch, and when safety button stretched out in shell, insurance stop portion and igniting trigger positive stop end held out against mutually.Like this, the igniting trigger just can't be pulled by the chucking locking.And when safety button was pressed, the insurance stop portion was separated from igniting trigger positive stop end, and the igniting trigger is not subjected to the control of safeties and can pulls igniting, the normal use.After using up, safeties automatically revert to safety position, and lighting a fire, trigger is locked can't be pulled.

The utility model has improved the safety coefficient of idea burning torch widely because above-mentioned automatic safety has been installed, and has solved present electronic ignition rifle poor reliability, uses inconvenience, and children play and easily go out dangerous problem.And the utility model has utilized elastomeric effect on the insurance depression bar, makes can automatically reply safety position after the burning torch igniting, need not the other action of additional staff, has realized the voluntary insurance function.

Be described further below in conjunction with accompanying drawing.

Fig. 9 is the schematic diagram that A portion amplifies among Fig. 7, burning torch is in normal operating condition.

In Fig. 1, Fig. 2 and embodiment shown in Figure 3, safeties are by insurance depression bar 1, safety button 2, and elastomer 3 and insurance stop portion 4 are formed.Insurance depression bar 1 is a lever, and its pin is fixed on the shell 5 of burning torch, and there is a circular hole 6 upper end of shell 5, and the safety button 2 on insurance depression bar 1 top passes from circular hole 6.Have an elastomer 3 on the insurance depression bar 1, elastomer 3 is a torsion spring, and the other end of torsion spring withstands on the shell 5, and the effect of elastic force makes the insurance stop portion 4 of insurance depression bar 1 the other end withstand on the trigger positive stop end 8 of burning torch trigger 7.The trigger positive stop end is a boss that is positioned at burning torch trigger 7 tops, and when it held out against mutually with insurance stop portion 4, burning torch trigger 7 was locked motionless, and burning torch can't use, and is in safety position.In the time will lighting a fire with burning torch, press safety button 2 with thumb, promote insurance depression bar 1 and move downward, insurance stop portion 4 is upwards lifted, break away from boss (being trigger positive stop end 8) on the burning torch trigger 7, pull burning torch trigger 7 use of can lighting a fire with forefinger again.After finishing using, staff leaves burning torch, and safety button 2 resets under the elastic force effect, the insurance depression bar 1 also under the elastic force effect to pressing down, the insurance stop portion 4 of its end is pushed up again and is got back on the boss, and burning torch trigger 7 is locked again motionless, and burning torch is in safety position.

In Fig. 4, Fig. 5, embodiment shown in Figure 6, its action principle is identical with first embodiment, different is, insurance depression bar 9 is straight-bars, and elastomer 10 is compression springs that are enclosed within on the insurance depression bar 9, insurance stop portion 11 is positioned at insurance depression bar 9 tops, be a T-shaped, it is corresponding with the trigger positive stop end 12 that is positioned at burning torch trigger upper side, when burning torch is in safety position, insurance stop portion 11 and trigger positive stop end 12 hold out against, and the burning torch trigger is locked motionless.When safety button was depressed, insurance stop portion and trigger positive stop end broke away from, and burning torch can normally use.Use up back insurance depression bar 9 and upwards push up under spring action, insurance stop portion 11 resets, and holds out against with trigger positive stop end 12 again, makes burning torch be in safety position again.

In Fig. 7, Fig. 8, embodiment shown in Figure 9, insurance depression bar 12 also is a straight-bar, and elastomer 10 is identical with second kind of embodiment, is a compression spring that is enclosed within insurance depression bar 12 bottoms.Insurance stop portion 13 is positioned at spring top, is a cylinder, and it withstands on the same axle with the insurance depression bar when safety position, and trigger positive stop end 14 is circular holes that are fixed in the burning torch rifle shell, and insurance depression bar 12 passes from circular hole.When safety position, because the effect of spring, insurance stop portion 13 is locked in the circular hole, because the motion of trigger has been limited in it and burning torch trigger 7 sidewall diebacks, makes burning torch be in safety position.When safety button 2 was used depress, insurance stop portion 13 and circular hole broke away from, and pull burning torch trigger 7 with forefinger, and insurance stop portion 13 is slided along the slideway in the rifle shell, and burning torch is in normal operating condition.After using up, the active force of spring makes safeties be returned to the safety position of network type electron gun trigger again.
