Abstract
The present invention relates to a safety mechanism for a lighter, which is used for preventing people from lighting a fire by mistake or preventing children from lighting a fire. The present invention comprises a pushing button arranged on a machine body, and a lock catch mechanism linking with the pushing button, wherein the lock catch mechanism comprises a lock catch and a push rod which is in transmission connection with the lock catch, a self weight moving body is arranged between a pushing plate on the pushing button and the push rod, and the pushing plate can be in transmission connection with the push rod only by passing through the self weight moving body; a self weight moving body chamber is arranged on the machine body, the self weight moving body is arranged in the self weight moving body chamber when the lighter is in a security state, an elastic body which causes the lock catch to be in a position-locking state is also arranged on the machine body, and the lock catch forms a position-locking fit with a lock pin or an igniting button on a head cover. The present invention has the advantages that because the movable self weight moving body is arranged between the pushing button and the push rod, the stroke of the pushing plate is subjected from certain limitation and the pushing plate keeps a certain gap with the push rod when the self weight moving body is arranged in the self weight moving body chamber, the pushing plate can not be in contact with the push rod no matter how to operate the pushing button, so the lock catch can not be unlocked, the igniting operation can not be carried out, and the present invention can be absolutely safe and reliable.
Description
Technical field:
The present invention relates to a kind of lighter, relate in particular to preventing mis-ignition or preventing the release mechanism that children light a fire of a kind of lighter.
Background technology:
At present, there is not its potential safety hazard of lighter of release mechanism to be familiar with by people gradually and to pay attention to, especially after country such as USA and Europe proposes the CR standard, the design of the safety device of a lot of lighter appears, through patent retrieval as can be known, its design principle is divided into three kinds basically: first kind is so-called " gravity lock " principle, promptly press hand when sparking when depressing, when pressing hand and running to a certain degree, run into a bigger elastic resistance, if will normally strike sparks, then need to strengthen consciously to pressing the pressure of hand, could normally strike sparks.As the patent No. is 97210601.4 Chinese utility model patent, employing be exactly this principle.Second kind is to be provided with one to press the hand retardance part that resets, and this retardance part plays retardation at the latter end of pressing the hand reseting procedure to pressing hand, makes to press hand under the conventional elastic force effect of piezoelectricity cap, can't be reset to the prefiring position fully.As number of patent application is that 03159063.2 the disclosed technical scheme of application for a patent for invention is exactly wherein a kind of.The third is that stop member is set.Under nature, the stop member of setting if want normal ignition, at first needs to carry out an extra unlocking operation to pressing the subordinate barrier effect of having gone.As the patent No. is 00251411.7 Chinese utility model patent, adopts this principle exactly.The disclosed technical scheme of this patent comprises shell, body and is located at sparking assembly on the body, be provided with safety knobs in body one side, its top is provided with the edge mate of step and button ignition switch, lower end and body are movable to be cooperated, be provided with smooth block at the safety knobs inner surface, free end and smooth block that an end is fixed on the spring leaf on the body cooperate.This technical scheme is the prior art the most approaching with the utility model, to press safety knobs earlier during use, just can press button ignition switch lights a fire, can play certain safety effect, but its safety device also is very much directly perceived, as long as the normal children is play several times more, just might release and light a fire, and its security reliability is also relatively poor.
Summary of the invention:
The present invention has overcome the deficiencies in the prior art, provides a kind of security reliability good safety mechanism for lighter.
The present invention solves the problems of the technologies described above one of technical scheme of being adopted: safety mechanism for lighter, comprise the push button that is arranged on the body and with the latching device of push button interlock, described latching device comprises snap close, the push rod that is in transmission connection with snap close, be provided with the deadweight moving body between push pedal on the described push button and the push rod, push pedal has only by the deadweight moving body and could be in transmission connection with push rod, described body is provided with deadweight moving body chamber, when lighter is in a safe condition, the deadweight moving body places deadweight moving body chamber, also be provided with the elastomer that snap close is had be in the lock-bit state trend on the described body, described snap close cooperates as lock-bit with lock pin on the skull.
The present invention solves the problems of the technologies described above two of the technical scheme that adopted: safety mechanism for lighter, comprise the push button that is arranged on the body and with the latching device of push button interlock, described latching device comprises snap close, the push rod that is in transmission connection with snap close, be provided with the deadweight moving body between push pedal on the described push button and the push rod, push pedal has only by the deadweight moving body and could be in transmission connection with push rod, described body is provided with deadweight moving body chamber, when lighter is in a safe condition, the deadweight moving body places deadweight moving body chamber, also be provided with the elastomer that snap close is had be in the lock-bit state trend on the described body, described snap close cooperates as lock-bit with button ignition switch.
The invention has the beneficial effects as follows: no matter be technical scheme one or two, its common main inventive point is to be provided with the moving body of movably conducting oneself with dignity between push button and push rod, when the deadweight moving body places deadweight moving body chamber, because the stroke of push pedal is subjected to certain restriction, and keep certain spacing, operate push button in any case with push rod, push pedal can't contact with push rod, also just can't untie snap close, ignition operation can't carry out, and it is perfectly safe reliably.
