Description

A kind of burning torch with safeties

Technical field

The utility model relates to ignitor, a kind of specifically burning torch 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, children, fire hazardous and operation easily when the mentally handicapped plays, the security performance of burning torch is relatively poor.

The utility model content

Technical problem to be solved in the utility model is the defective that overcomes above-mentioned prior art, and a kind of burning torch with safeties is provided, and to increase the difficulty of children's operation, improves the security performance of burning torch.

For this reason, the utility model is by the following technical solutions: a kind of burning torch with safeties, comprise housing, place the oil groove in the housing, what be positioned at oil groove top goes out pneumatic module and ignition module, one routine wall of housing is provided with presses hand, another sidewall forms an arc notch, it is characterized in that being provided with in the housing and pressing a slide block and a lead of hand interlock, the upper end of slide block cooperates with ignition module, the lower end of slide block is connected with the upper end of lead, the lower end of lead with go out pneumatic module and be connected, be with the spring that a lower end is positioned on this lead, conflict one on the locking plate that fulcrum rotates in the upper end of this spring, this locking plate is enclosed within on the lead, and the housing that is positioned at indentation, there is provided with the safety button of an oblique setting, the bottom of this safety button has a groove or following breach, one end of described locking plate places in groove or the following breach, is provided with return unit between safety button and housing, under the normality, the top of safety button is exposed to outside the housing, and locking plate is conflicted on lead.The utility model is (being under the safety position) under normal conditions, because locking plate is conflicted on lead, there is bigger frictional force between locking plate and the lead, lead can't be moved upward, operation this moment is pressed hand and can't be lighted inflammable gas, prevent children's maloperation effectively, improved the burning torch security performance.

The course of work of the present utility model is as follows: the oblique safety button of pushing of elder generation, the oblique end that pushes away locking plate of inwall of groove of its underpart or following breach, locking plate is rotated around fulcrum, when button press on earth the time (arcwall face at the upper surface of button and arc notch place flushes), zerofriction force between the locking plate of this moment and the lead, spring under the locking plate is compressed, meanwhile, promote to press hand forward, slide block, lead move forward with pressing hand, and when pressing the hand stroke and finish, the stroke of piezoelectricity push rod is also finished, piezoelectricity produces electric spark, and inflammable gas is lighted.Safety button utilizes return unit to reset, and locking plate utilizes the restoring force of spring to reset.

The burning torch of described band safeties, lead is axially disposed within the housing, locking plate is the in an acute angle or obtuse angle with lead under normal conditions, in working order down, locking plate is vertical with lead, this is a kind of implementation that makes the frictional force that existence is bigger between locking plate and lead, the also mode that can take other to be equal to.Allly take to make the technical scheme of the frictional force that existence is bigger between locking plate and lead all to fall into protection domain of the present utility model.

The burning torch of described band safeties, return unit are V-shaped flexure strip, and the one end is connected on the inner walls, and the other end is connected on the sidewall of safety button.The return unit of this kind form can with the machine-shaping of safety button one, to reduce cost, can certainly adopt the return unit of other form.

The burning torch of described band safeties, described return unit has two, is arranged on the both sides of safety button, and it is reliable and stable that safety button is resetted.

The burning torch of described band safeties, described locking plate is L-shaped, and conflicted by spring in the long limit of described " L ", and minor face is positioned between fulcrum and inner walls, and it is spacing preferably that minor face is obtained.

The burning torch of described band safeties, described slide block is provided with a projection, the madial wall of pressing hand is provided with a step that cooperates with projection, realizes pressing the interlock of hand and slip by the projection that the step of pressing on hand promotes on the slide block, thereby also can drive lead.

The burning torch of described band safeties, described lead is connected with skid plate in going out pneumatic module, thereby realizes lead and the interlock that goes out pneumatic module.

The burning torch of described band safeties has salient point on the described lateral wall of pressing hand, increases hand and presses frictional force between hand.

The utility model is controlled the duty of pressing hand by the acting in conjunction of safety button and locking plate, has following beneficial effect: increased the difficulty of child's operation, prevented maloperation effectively, improved the burning torch security performance; Resetting of locking plate and safety button is stable, reliable.

Below in conjunction with drawings and Examples the utility model is further described.
