Back striking lighter safety lock

Abstract

The present invention relates to a back-lighted type lighter safety lock. It is characterized by that a secret pin is set in the interior of machine head, said secret pin is a lever mechanism, the pivot of said lever is the pin shaft set on the machine head, the right arm of said lever is extended towards outer side wall of machine body, the left arm of said lever is extended into the machine head interior; on the top cover of said machine head a long hole is set along the sliding direction of machine head, the top cover of said machine head is covered by using an opening-closing knob, said opening-closing knob is slide-fit with the top cover of machine head, a starting bar is fixedly-placed in the bottom portion of said opening-closing knob, said starting bar is passed through long hole and is placed in the machine head interior, the bar end of said starting bar is used as drive end for driving left arm of said lever; on the pin shaft a torsion spring is set, the bottom end of said torsion spring is fastened on the right arm of lever, the upper end of said torsion spring is formed into 'V'-shaped elastic structure. Said invention also provided the working principle of said back-lighted type lighter safety lock and its concrete operation method.

Description

technical field

[0001] The invention relates to a lighter safety lock. More specifically, it is a safety lock for a back strike type electronic lighter. Background technique

[0002] Back-type electronic lighters are widely used in daily life. Because of their low price and easy operation, children like to play very much, and often cause fire hazards due to improper use. For this reason, some countries and organizations in Europe and the United States have introduced CR bills to restrict or even prohibit the production and sale of electronic lighters without safety locks in their territories. In order to limit children's use and not affect the daily application of the product, various lighters with locking devices have been designed to prevent children from using the lighter without authorization by causing certain difficulties for children to use the lighter. However, due to the complex design and cumbersome operation of various existing locking devices, the cost of the l...
