Description

A kind of lighter with opening-prevention structure

Technical field

The invention belongs to lighter technology fields, are related to a kind of lighter with opening-prevention structure.

Background technique

Lighter main component is that firing device and air receiver burst out spark directive combustion gas area when firing device acts, Combustion gas is ignited, firing device is most active part and the more complex part of structure during lighter develops, according to ignitor The characteristics of structure, lighter can be divided into flint steel cigarette lighters, piezoelectric ceramic igniting machine, magnetic induction lighter, battery lighter, too Positive energy lighter, micro computer lighter etc..The gas that lighter uses is mainly imflammable gas, and early stage is mostly used gasoline, modern more With butane, propane class and oil liquefied gas, be filled with air receiver after they are pressurized, once be discharged into air just endothermic gasification and Expansion rapidly, is easily lighted.Since lighter can burst out spark by firing device, when child takes sparking There are some potential safety problemss when machine.

Summary of the invention

The purpose of the present invention is there is the above problem in view of the prior art, a kind of beating with opening-prevention structure is proposed Lighter, there is the lighter of opening-prevention structure can fix lid when cover cap closes, prevent child from opening, safety for this It is higher.

Object of the invention can be realized by the following technical scheme: a kind of lighter with opening-prevention structure, including A side edge of the casing of strip and the firing device and lid that casing upper end is arranged in, the casing upper end offers connection Slot, connecting pin is slidably connected in the link slot in the width direction, and one end edge of the lid has interconnecting piece, the company Socket part is rotatably connected on connecting pin, and casing lateral wall is stretched out in one end of the connecting pin, and the other end is fixed with positioning disk, described The disk of positioning disk is opposite with interconnecting piece side, and positioning disk and casing are circumferentially fixed, and positioning bullet is additionally provided in the link slot Spring, one end of the retaining spring are pressed in connection groove groove wall, and the other end is pressed on positioning disk, the positioning disk and interconnecting piece Between be equipped with locating piece, locating piece can fix lid under the action of retaining spring.

Firing device is for striking sparks when Cover opening, and when not in use, cover cap is closed in the end of casing, i.e. firing device It is housed in lid, at this time under the action of retaining spring, positioning disk can be resisted against on interconnecting piece, therefore positioning disk and connection Locating piece between portion can generate effect, so that lid is fixed, child be avoided to open, and safety is higher, need to make Used time, Manual press connecting pin, connecting pin positioning disk can be made to overcome the elastic force of retaining spring and far from interconnecting piece, i.e. locating piece The detent force to lid is released, it is easy to operate.

In the above-mentioned lighter with opening-prevention structure, connecting hole is offered on the side cell wall of the link slot, Above-mentioned connecting pin slides through connecting hole, offers circular mounting slot on the opposite cell wall of link slot, the mounting groove and connecting hole Concentric setting offers two guide grooves on the cell wall of the mounting groove, the length direction of two guide groove and the axis of mounting groove To consistent, the outer edge of the positioning disk has two guide pads, and the guide pad is slidably connected at guide groove.Positioning disk passes through two Guide pad and two guide grooves are cooperatively connected in mounting groove, i.e., positioning disk can move axially, but can not circumferentially rotate, real Now to the positioning of interconnecting piece.

In the above-mentioned lighter with opening-prevention structure, the locating piece includes several in positioning disk disk Positioning convex body, several positioning convex bodies are circumferentially uniformly distributed, and offer several locating slots on the interconnecting piece side, this is several fixed Position grooved ring is circumferentially uniformly distributed around connecting pin, and under the action of retaining spring, positioning convex body is pressed in locating slot.I.e. in retaining spring Under the action of, positioning convex body is pressed in locating slot, realizes the positioning to interconnecting piece, and when pressing connecting pin, positioning convex body can It is detached from locating slot.

It is vertical in the disk of the positioning disk direction installation groove bottom in the above-mentioned lighter with opening-prevention structure With connecting column, the connecting column is located at the center location of positioning disk, and the retaining spring is set on connecting column, and positions bullet One end of spring is pressed in positioning disk disk, and the other end is pressed in installation groove bottom.Connecting column positions retaining spring, Retaining spring is avoided to shift or bend.

In the above-mentioned lighter with opening-prevention structure, also opened up along casing length direction in the connection groove bottom There is strip groove, the elastic sheet metal of strip is fixed in the strip groove, the middle part arc of the sheet metal protrudes strip groove, institute Interconnecting piece is stated in rectangle, there are two perpendicular abutment faces, when cover cap closes on casing sheet metal be pressed on one against On face, when Cover opening, sheet metal is pressed on another abutment face.The middle part of sheet metal is supported with one of interconnecting piece always It is pressed against each other by face, is positioned to close two states in unlatching and lid to lid, so that operation is more convenient.

In the above-mentioned lighter with opening-prevention structure, arc-shaped transition between two abutment faces of the interconnecting piece.Make Unlatching and the lid conjunction process for obtaining lid are more smooth, and operating handle is more preferable.

Compared with prior art, there are the lighter tools of opening-prevention structure to have the advantage that for this

1, since under the action of retaining spring, positioning disk can be resisted against on interconnecting piece, i.e., positioning convex body can compress In locating slot, so that lid is fixed, child is avoided to open, safety is higher.

2, due to needing in use, Manual press connecting pin, connecting pin can make positioning disk overcome the elastic force of retaining spring And far from interconnecting piece, i.e. positioning convex body is detached from locating slot, easy to operate.

3, since the middle part of sheet metal is pressed against each other with an abutment face of interconnecting piece always, so that lid is being opened and covered It closes two states to be positioned, so that structure is more stable, operate more convenient.
