Abstract

The invention relates to a safe lock for lighter (device against children opening), comprising body, head, thrumbing hand, electron, characterized in that thrumbing hand is set between inner of head and electron and the shaft of thrumbing hand is set in the U-shaped groove in head so that the shaft can rotate in the U-shaped groove in head and move up-down; and thrumbing hand is hold to the top of head by the self spring force of electron all the time and does not drop down freely. By the shaft of thrumbing hand, there are the following activities of thrumbing hand in head: M status, thrumbing hand is locked in head, here the distance between the axes of thrumbing hand to the D point of thrumbing hand (radius) is larger than the distance between the axes of thrumbing hand to the H point of head top (radius), namely oD>oH. When the F surface of thrumbing hand is turned upwards the D point of thrumbing hand is hindered by H point of head so that it is not turned successfully. Here thrumbing hand is locked (M status) and it is not run. The safe and protection effect is achieved.

Description

Lighter safety lock

Technical field

The present invention relates to a kind of lighter safety lock.

Background technology

Lighter is a kind of articles for daily use that people generally use, and still, the lighter that uses is not all adorned safety lock---Childproof device mostly at present, because the young ignorant of children, and curiosity is strong, can often play with lighter, thereby causes very big potential safety hazard.

Summary of the invention

The purpose of this invention is to provide a kind of lighter safety lock---the Childproof device,

To achieve these goals, technical solution of the present invention is such: safety lock mainly by fuselage, head, press hand, electronics is formed, press hand be contained in the head and electronics between, and pressing the hand axle is contained in the interior U type groove of head, make and press the hand axle and can be in head rotate in the U type groove and up and down, and press the spring force that hand had by oneself by electronics and press closer all the time on the head inner roof wall, can freely not fall.

Because above-mentioned technical solution arranged, so press hand and can in head, mainly contain following four active states by pressing the hand axle, making:

The M state---press hand and be in locking-in state in head, press hand and be lockable this moment, can't start, and plays the safeguard protection effect, reaches the purpose of safety lock of the present invention;

The N state---press hand and in head, be in released state;

The P state---press hand and in head, be in and wait to drive the electronic ignition state;

The W state---press hand and in head, be in and drive electronics and finish igniting back state.

The invention has the beneficial effects as follows, when children play with lighter, can prevent to open by mistake to open, play the safeguard protection effect, eliminate safe hidden trouble.

The specific embodiment

In embodiment illustrated in fig. 2, want to make electronics (6) igniting, must will press hand (4) down presses, could drive electronics (6) igniting, and press the E face of only pressing hand (4) and the F face that hand (4) is exposed at head (2) outside, and the E face of pressing hand (4) does not far reach electronics (6) to the distance (highly) of the G face of head (2) and lights a fire required distance (highly) 1., can't work after the E face is pressed, can only come back after a vain attempt, unclamp and press hand (4) behind the E face and pressed closer reposition by the own spring force of electronics (6).The F face of pressing hand (4) up to be turned over and turn 90 degrees; but press the distance of ordering to the D that presses hand (4) in hand axle center (o) (radius) this moment; greater than pressing the distance of ordering to the inner roof wall H of head (2) in hand axle center (o) (radius); be oD＞oH; the D point of pressing hand (4) when the F face of pressing hand (4) up overturns is stopped by the H point of head (2); turn on can't be smoothly; therefore the hand (4) of pressing of this moment has been in the state that is lockable---the M state; pressing hand (4) can't start; play the safeguard protection effect, reached the order ground of safety lock of the present invention.

As shown in Figure 7, press hand (4) and in head (2), be in the release shape---the N state; Since the E face of pressing hand (4) to the D identity distance of pressing hand (4) from (highly) greater than the roof G of head (2) thickness (highly) to H, as long as will press the E face of hand (4) presses, just can make the D point of pressing hand (4) be lower than the H point of head (2), and pin, just become to attack release, at this moment the D point of pressing hand (4) has been lower than the H point of head (2), so the H point can't stop that pressing hand (4) up overturns, at this moment the F face of pressing hand (4) just can up turn over smoothly and turn 90 degrees, be in electronics to be driven (6) fired state---P state, must be pointed out, these two actions will link up and finish, and can not separate, and the E face that is about to press hand (4) is pressed, and pin, at this moment the F face of pressing hand (4) could up turn over smoothly and turn 90 degrees, otherwise inoperative, just unclamps after pressing as the E face that will press hand (4), will be pressed closer reposition by the own spring force of electronics (6), be in the shape of pinning again---the M state.

Release also can be explained like this: the E face that will press hand (4) is down pressed, just equal to have elongated and press the distance of ordering to the H of head (2) in hand axle center (o), and the D point of pressing hand axle center (o) and pressing hand (4) is because of coexisting one on the whole, and therefore no matter what are pressed, the distance between them is still constant, so, after pressing the E face, and pin, at this moment oH＞oD, the F face is up turned over turn 90 degrees, make and press hand (4) and be in electronics to be driven (6) fired state---P state.

As shown in Figure 8, press hand (4) and in head (2), be in electronics to be driven (6) fired state---P state, at this moment, the F face of pressing hand (4) to the G identity distance of head (2) from (highly) greater than the required distance (highly) of electronics (6) igniting, just can drive electronics (6) smoothly and light a fire so press the F face of pressing hand (4).

As shown in Figure 9, press hand (4) and drive state---W state after electronics (6) is finished igniting.

After finishing; unclamp the F face; pressing hand (4) duration and degree of heating by on the own spring force top of electronics (6) time is closed; the F face that to press hand (4) down turns over to turn 90 degrees just gets back to the original place again; promptly pin shape---the M state, press hand (4) and be lockable again this moment, can't start; play the safeguard protection effect again, reach the purpose of safety lock of the present invention.

1. electronics (6) need be pressed certain distance (highly) and could light a fire, and because of electronics (6) is not a theme of the present invention, it is bright just not speak more.
