Description

The safety lock of the lighter improvement structure of pulling

Technical field

The safety lock that the utility model the relates to a kind of lighter improvement structure of pulling specifically is meant and a kind ofly can effectively prevents careless person or the careless and unexpected operation lighter of child, the safety lock of avoiding the producing fire hazard structure of pulling.

Background technology

Lighter has the function that is easy to ignite, and its use also very convenient, therefore, oneself become gradually in modern's life indispensable daily necessities; Yet, because having to use, it goes up clear and easy to understand convenience, also easily, the child causes accident for playing.Therefore, how can be under modern lighter basic framework easy to use, increase the safety lock structure of pulling, to prevent that child or shortcoming judgement person from using lighter arbitrarily to light a fire, taking place with the accident that prevents fire, is to be a basic safety requirements, also is a product trend.

Known lighter structure with security mechanism, " lighter " patent case just like Taiwan patent announcement No. 579413 (applying for No. 91103611) with anti-child's use of a deflection breech lock, it mainly comprises a latch member, in its initial conditions is the mobile operation with the prevention lighter that stops starter, this latch member is movable to a cocked orientation, can be pressed to produce flame in order to do starter, and this lighter can comprise extra or alternative strength on latch member, can return back to the strength that stops the position to promote latch member, and promote moving and the consistency of replying of latch member; Yet, in each embodiment that is disclosed in its patent specification, the lock that obviously can find its latch member control structure of pulling is located at the starter side, and after pushing, can remove the state of pulling of locking, so, the user is casual when holding near (pressure) this starter the position, still has feasible solution to remove lock and pulls and touch the starter igniting, and this is a big leak of its security mechanism.

Have the lighter structure of security mechanism that above-mentioned shortcoming is arranged because habit is known, the inventor is the road at those shortcoming research improvement, has the utility model to produce finally.

The utility model content
