Abstract
The utility model involves in a kind of rotary sleeve cover type safety device of lighter including piezolighter 1, button 6 and a rotational structure used to resist pressing down the button. One point of inner side of rotary sleeve cover 2 is connected with one end of a back spring 5, and the other end of the back spring 5 is connected with spring pilot pin 4 arranged in the middle of the button 6 and piezolighter 1. The anchor point 3 locates the rotary sleeve cover 2 when the back spring 5 is relaxed. When it is to ignite, the rotary sleeve cover 2 is pushed to leave anchor point 3 and parallel to the button 6, then the rotary sleeve cover 2 is pressed down to drive the button 6 touching with piezolighter 1. The step of rotating before agitation insures that children indifferent to safety awareness can not strike fire successfully, thereby guaranteeing the safety of life and property.
Description
Technical field
The utility model relates to a kind of lighter, relates in particular in this lighter at prefiring safeties.
Background technology
The U.S. carried out the CR bill comprehensively in 1994 in the world, European Union adds after-tax from the import of nineteen ninety-five and twice pair of disposable lighter in 1999, had passed through the rules (CR bill) that the lighter below 2 Euros must install safety lock additional in 2002.So-called CR (CHILDR ESISTANCE) bill is meant to install additional on lighter and prevents the child device, to improve the lighter security performance.
Existing lighter has various styles, the lid of unlatching and the button of igniting also be have a variety of; As shown in Figure 1: be a kind of lighter commonly used, main piezoelectrics 1, air storage chamber 10, drive atmospheric pressure pole 9, nozzles 8, high-voltage line 7 and button 6 and form; When button down on time, be pressed onto piezoelectrics, at this moment lighter just can fire.But the lighter of this style is disadvantageous to 5 years old children, because he can light a fire very easily, brings hidden danger to safety.
Summary of the invention
The utility model technical issues that need to address have provided rotary sleeve cover type safety device in a kind of lighter, are intended to solve above-mentioned defective.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises piezoelectrics, button; Also comprise one can stop button down by rotational structure; Described rotational structure comprises a rotation upper shield, an anchor point of fixing with lighter casing, spring holder, return spring; A bit being connected with an end of return spring of described rotation upper shield inboard, the other end of return spring links to each other with spring holder, and spring holder is placed between button and the piezoelectrics; Described anchor point will rotate upper shield location when return spring is lax; When needs are lighted a fire, promote the rotation upper shield, make the rotation upper shield leave anchor point and parallel with button, contact with piezoelectrics by rotating upper shield and driving button downwards again;
Compared with prior art, the beneficial effects of the utility model are: owing to before igniting the step of a rotation is arranged earlier, added a lock to safety, guaranteed the thin children of the awareness of safety success of can't striking sparks, guaranteed the safety of the person and property.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As seen from Figure 2: the utility model comprises piezoelectrics 1, button 6; Also comprise one can stop button down by rotational structure; Described rotational structure comprises 2, one anchor points of fixing with lighter casing 3 of a rotation upper shield, spring holder 4, return spring 5; A bit being connected with an end of return spring 5 of described rotation upper shield 2 inboards, the other end of return spring 5 links to each other with spring holder 4, and spring holder 4 is placed between button 6 and the piezoelectrics 1; Described anchor point 3 will rotate upper shield 2 location when return spring 5 relaxes; When needs are lighted a fire, promote rotation upper shield 2, make rotation upper shield 2 leave anchor point 3 and parallel with button 6, contact with piezoelectrics 1 by rotating upper shield 2 and driving button 6 downwards again.
Lock-out state
Locking-in state is as shown in Figure 3A:
Because the existence of rotation upper shield, the user presses down buttons force and is obstructed, and can not press to normal position, promptly can not start the piezoelectricity fire maker, and this moment, lighter was in the lock state.
Releasing process
Releasing process is shown in Fig. 3 B:
User's application of force upwards promotes the rotation upper shield, will rotate upper shield and progressively be pushed to directly over the button, and lighter is in just progressively release.
Release is finished
The release completion status shown in Fig. 3 C,
The user overlaps rotation upper shield and button (6) to the rotation upper shield application of force fully, and the lighter restriction is eliminated, and release is finished, and lighter can normally be struck sparks.
The utility model lighter state and use can be divided into following a few part:
The lighter locking
Shown in Fig. 4 A, button is limited by the rotation upper shield, and the user can not start the piezoelectricity fire maker by the button down application of force, also promptly can not normally strike sparks, and lighter is in the lock state.
The lighter release
Shown in Fig. 4 B, the user rotates up upper shield, and it is progressively overlapped with button, and release is finished.
Lighter is normally struck sparks
Shown in Fig. 4 C, after the user finishes release, guarantee to rotate upper shield and go to dominant bit.
Shown in Fig. 4 D, can push pushbutton enable piezoelectricity fire maker downwards and light the gas that ejects from air storage chamber normal sparking as the sparking press proof.
The lighter reset locking
Shown in Fig. 4 E, the user will rotate under the upper shield and be pushed into raw bits, the locking lighter, and lighter can not normally be struck sparks, and is in the lock state again.
Claims (1)
1. rotary sleeve cover type safety device in the lighter comprises piezoelectrics (1), button (6); It is characterized in that: also comprise one can stop button down by rotational structure; Described rotational structure comprises a rotation upper shield (2), an anchor point (3) of fixing with lighter casing, spring holder (4), return spring (5); What described rotation upper shield (2) was inboard a bit is connected with an end of return spring (5), and the other end of return spring (5) links to each other with spring holder (4), and spring holder (4) is placed between button (6) and the piezoelectrics (1); Described anchor point (3) will rotate upper shield (2) location when return spring (5) is lax; When needs were lighted a fire, promotion rotation upper shield (2) made rotation upper shield (2) leave anchor point (3) and parallel with button (6), contacted with piezoelectrics (1) by rotating upper shield (2) and driving button (6) downwards again.
