Background technique
Present desk-top gas range Safety valve generally adopts be the patent No. 03224487.8 decide the power starting mechanism.But this kind starting mechanism has shortcoming, at first it is 1: 1 by cam generation power ratio, because through a plurality of part transmission such as rotating shaft, cam bit, push rod, counterbalance springs, actual stroke ratio is less than 1: 1, therefore has the problem that to open security solenoid valve and exist; Secondly this mechanism requires safety valve to become vertical angle with rotating shaft, make inlet flange angled with rotating shaft or parallel, assembling kitchen range suction tude is very difficult when angled, and assembling kitchen range accessory will eject a nest slightly because of carelessness when parallel at kitchen range panel place, influences outward appearance.Though I can overcome the above problems No. 2008201339588 patents of application, owing to still adopt counterbalance spring, what make security solenoid valve opens the valve instability, and increases product cost.
Summary of the invention
The purpose of this utility model is to provide a kind of security solenoid valve of opening easily, and gas range Safety valve linking mechanism stable and reliable for performance makes gas range Safety valve performance better, and saves cost.
A kind of gas range Safety valve linking mechanism, relate to gas range valve, security solenoid valve, it is characterized in that security solenoid valve is contained on the valve body of gas range valve, in the rotating shaft of gas range valve, cam is housed, in the valve seat of gas range valve, be provided with the passage of a band square frame, push rod is housed in passage, the front end of push rod withstands on the convex surface edge of cam, the rear end of push rod withstands on the arc place of hook-type lever in the square frame, the hook-type lever is by a pivot pin location, the front end of hook-type lever has push rod, withstands on the spool front end of security solenoid valve.
Aforesaid a kind of gas range Safety valve linking mechanism is characterized in that being equipped with Returnning spring on push rod.
Aforesaid a kind of gas range Safety valve linking mechanism, it is characterized in that the gas range valve is fastened as one by screw by valve seat and valve body, the passage top of band square frame is covered by screw by a sheet metal, influences function of use in the passage to prevent that foreign material from falling into.
Aforesaid a kind of gas range Safety valve linking mechanism is characterized in that there is the slope of two symmetries the cam lower end, and there is the curved flanges of a scope less than 90 degree on the right side, has radius on the curved flanges and becomes big tilted conical surface gradually.
Advantage of the present utility model is to open easily security solenoid valve, and is stable and reliable for performance, saves cost, applicable to the use of gas range Safety valve.

Embodiment
The utility model relates to gas range valve (1), security solenoid valve (2).Gas range valve (1) comprises valve seat (6) and valve body (3) two major parts, and fastens as one by screw, and security solenoid valve (2) is contained on the valve body (3).In the rotating shaft (4) of gas range valve (1) cam (5) is housed, the slotted hole that cam (5) utilizes its center to open cooperates with the corresponding flat position of rotating shaft (4), just drives cam (5) when making rotating shaft (4) rotate and rotates together.In valve seat (6), be provided with the passage (7) of a band square frame, push rod (8) is housed in passage (7), the front end of push rod (8) withstands on the flange of cam (5), the rear end of push rod (8) withstands on the arc place of hook-type lever (9) in the square frame, hook-type lever (9) is by a pivot pin (10) location, the front end of hook-type lever (9) has push rod (11), withstands on the spool front end of security solenoid valve (2).
Valve seat (6) is gone up passage (7) the interior setting hook shape lever (9) of band square frame, locatees by a pivot pin (10) by hook-type lever (9).Because the effect of Returnning spring (12), the square frame inwall is close at the arc place of hook-type lever (9).
Working principle of the present utility model is: when depressing rotating shaft (4) when being rotated counterclockwise, driving cam (5) rotates, because the front end of push rod (8) withstands on the flange of cam (5), therefore push rod (8) can be to the arc prescription of hook-type lever (9) to being subjected to displacement when cam (5) rotates, and the shift length increasing along with the increase of cam (5) angle of swing.Push rod (8) makes hook-type lever (9) rotation, and the hook-type lever (9) of rotation makes push rod (11) be subjected to displacement to security solenoid valve (2) direction, finally backs down security solenoid valve (2), makes blast tube open.Behind gas combustion range ignition, heating is contained in the thermocouple on fire lid next door, produces electric current, makes security solenoid valve (2) adhesive.The operator looses one's grip, and rotating shaft (4) and cam (5) set back.If the spool (17) in rotating shaft (4) then the valve body (3) rotates simultaneously.Relatively rotating of spool (17) and valve body (3) amassed the blast tube opening section and changed, thereby reaches the purpose of regulating the combustion gas firepower.When stopping working when meeting accident, security solenoid valve (2) makes valve-closing because of signal code stops to lose magnetic attraction, thereby cuts off blast tube, to avoid taking place dangerous accident.
It is 2.5mm that security solenoid valve (2) is opened Valve travel, the maximum shift length of push rod (8) was 3.5mm when cam (5) rotated, because through rotating shaft (4), cam (5), push rod (8), push rod a plurality of part transmission such as (11), if it is improper that machining accuracy has slightly, arrive security solenoid valve (2) shift length probably less than 2.5mm, hook-type lever (9) is exactly that special solution stroke is not enough, as long as slightly with the stroke ratio amplification of lever, can open security solenoid valve (2) easily.Have radius on the curved flanges (15) of cam (5) and become big tilted conical surface (16) gradually, be afterwards to move on the cam (5) in order to guarantee that security solenoid valve (2) push up and to put in place, rotating shaft (4) can be rotated smoothly, it can prevent that the dead top security solenoid valve (2) of push rod (11) back strength is excessive simultaneously, and destroys security solenoid valve (2).Secondly, because security solenoid valve (2) is parallel with rotating shaft (4), inlet flange (18) can be made with rotating shaft (4) and become vertical angle, and such mode and original general gas kitchen range valve basically identical are easy to install and replace.Owing to save counterbalance spring, saved cost of material, cost of labor, and lacked the machining error of a part simultaneously, it is more convenient that production is more saved.
