Safety igniting gun
[technical field]
The utility model relates to ignitor, specifically a kind of safety igniting gun that is provided with safeties.
[background technology]
The existing electronic ignition rifle that adopts single safety switch, promptly be provided with a block at the stroke place of pressing hand, be connected with a safety switch with the burning torch surface of this block relevant position, be in the block of pressing on the hand stroke, thereby reach the purpose that hand is pressed in control but move this safety switch clutch.When safety switch is in " opening " position, press hand and can move, piezoelectricity is emitted sparks light gas generation flare; When safety switch is in " pass " position, press hand and be restricted, can't move.But this burning torch just plays the security insurance effect when only being in " pass " position at safety switch, after igniting finishes, as if forgetting safety switch is allocated to " pass " position, then this switch performs practically no function, child, fire hazardous and operation easily when the mentally handicapped plays, the security performance of burning torch is relatively poor.
[utility model content]
The technical assignment of technical problem to be solved in the utility model and proposition is the defective that overcomes above-mentioned prior art, a kind of safety igniting gun that is provided with safeties is provided, increase the difficulty of children's operation, can effectively prevent maloperation, avoid children's burning torch of playing to cause fire or contingency, improve the security performance of burning torch.
The technical solution of the utility model is such: safety igniting gun, comprise housing, be installed in housing top gun barrel, place the oil groove in the housing, the hand of pressing that is located at the piezoelectricity and the piezoelectricity push rod of oil groove top and is positioned at piezoelectricity push rod top, it is characterized in that being provided with in the housing part and place the outer insurance push button of housing, insurance push button top is useful on the slotted eye that it moves up and down, and lower inside has a step block of conflicting with its underpart; Insurance push button inboard is provided with a pivoted arm of being close to its madial wall, the upper axis of pivoted arm is connected on the housing, be provided with upper spring between pivoted arm top and insurance push button, the bottom of pivoted arm and one is connected the bend shape shrapnel of pressing on hand and cooperates, bend shape shrapnel lower knuckle and depart from piezoelectricity push rod top, the bottom of pivoted arm and press and be provided with lower spring between hand.
Under the safety position (being normality), upper and lower spring is in the normal state, and piezoelectricity push rod top is departed from the bend shape shrapnel bottom, and directly push when pressing hand with pointing this moment, presses to hand down movingly, and lower spring is compressed earlier, moves down with pressing hand then.After the stroke of pressing hand finished, the stroke of piezoelectricity push rod did not reach the igniting stroke, and this is because being compressed in the process of lower spring, pressing hand is to move down, but the piezoelectricity push rod does not move down with it.Have only after lower spring is compressed to the end piezoelectricity push rod to be pressed hand propelled, the decrement of lower spring has taken a part of stroke of pressing hand, make the stroke of piezoelectricity push rod can not reach the igniting stroke,, and press the skid plate that palmistry joins and also can't open air outlet valve so piezoelectricity can't produce electric spark.
Under the duty, upwards promote earlier safety button, making it the bottom breaks away from the side of step block and slides on the step surface of block, the insurance push button deflects to the inside, pivoted arm is also thereupon around axial intrinsic deflection, and pivoted arm is in deflection, and lower spring is partly compressed, the side of pivoted arm inwardly promotes the bend shape shrapnel bottom, makes the bend shape shrapnel bottom stretch and directly conflict on the upper surface of piezoelectricity push rod; At this moment, push downwards and press hand, move together in company with pressing hand in the shell fragment bottom, owing to directly conflict on the upper surface of piezoelectricity push rod in the shell fragment bottom, after the stroke of pressing hand finished, the stroke of piezoelectricity push rod just can reach the igniting stroke, and piezoelectricity produces electric spark, meanwhile skid plate is also opened air outlet valve, and the inflammable gas of burning torch is lighted.
Described safety igniting gun, piezoelectricity push rod top have a piezoelectricity cap that is connected as a single entity with it, this piezoelectricity cap and press and be provided with a back-moving spring between hand, and piezoelectricity cap top is departed from the bend shape shrapnel bottom.Back-moving spring makes the reset speed that feel is better and hand is pressed in quickening when pressing hand operated, and the piezoelectricity cap is used for the location of back-moving spring one end.
The duty that the utility model is controlled the piezoelectricity push rod by the disengaging or the conflict on bend shape shrapnel bottom and piezoelectricity push rod top, thereby control the igniting stroke, the safety position that has only first arming push button, and then push downwards and press hand ability firing point firelock, increased the difficulty of children's operations, can prevent maloperation effectively, improve the burning torch security performance.

[specific embodiment]
As shown in Figure 1, 2, safety igniting gun, comprise housing 1, be installed in housing top gun barrel 2, place oil groove 3 in the housing, be located at the piezoelectricity 4 and the piezoelectricity push rod 5 of oil groove top and be positioned at piezoelectricity push rod top press hand 6, piezoelectricity 4 is with outward and presses the skid plate 15 that hand 6 bottoms cooperate, the other end of skid plate 15 cooperates with air-out needle 16, air outlet valve 17, wireway 18 and lead 19 assemble in the usual way, the one piezoelectricity cap 13 that is connected as a single entity with it is arranged at piezoelectricity push rod 5 tops, piezoelectricity cap 13 and press 6 in hand and be provided with back-moving spring 14.Be provided with a part in the housing and place the outer insurance push button 7 of housing, insurance push button 7 tops are useful on the slotted eye (not shown) that it moves up and down, the step block 8 that lower inside has a sidewall and its underpart to conflict.Insurance push button 7 inboards are provided with a pivoted arm 9 of being close to its madial wall, the upper axis of pivoted arm 9 is connected on the inner walls, be provided with upper spring 10 between pivoted arm 9 tops and insurance push button, the bottom of pivoted arm 9 and one is connected bend shape shrapnel 11 bottoms of pressing on hand and cooperates, bend shape shrapnel 11 lower knuckles and depart from piezoelectricity cap 13 tops, the bottom of pivoted arm 9 and press and be provided with lower spring 12 between hand, lower spring 12 both had been used for resetting of pivoted arm, also was used to press resetting of hand.
Under the safety position, upper and lower spring is in the normal state, and piezoelectricity push rod top is departed from the bend shape shrapnel bottom, and directly push when pressing hand with pointing this moment, presses to hand down movingly, and lower spring is compressed earlier, moves down with pressing hand then.After the stroke of pressing hand finished, the stroke of piezoelectricity push rod did not reach the igniting stroke, and piezoelectricity can't produce electric spark, and pressing subordinate portion also can't be with skid plate to moving down, and skid plate can't be opened air outlet valve, as shown in Figure 3.
Under the duty, upwards promote earlier the safety button (see figure 4), making it the bottom breaks away from the side of step block and slides on the step surface of block, the insurance push button deflects to the inside, has removed insurance and has made the bend shape shrapnel bottom (see figure 5) on the upper surface of piezoelectricity cap of stretching and directly conflict; Meanwhile push fully downwards and press the hand (see figure 6), the shell fragment bottom is synchronized with the movement in company with pressing hand, after the stroke of pressing hand finishes, the stroke of piezoelectricity push rod has reached the igniting stroke, piezoelectricity produces electric spark, and meanwhile skid plate is also opened air outlet valve, and the inflammable gas of burning torch is lighted.
