Abstract

The utility model discloses a gas combustion timing automatic turning-off apparatus belonging to an apparatus which uses a mechanical mode to control the combustion. The gas combustion timing automatic turning-off apparatus comprises a mounting plate (1), a disc (2), a disc holder (3), a lock pawl (6), a timer (11) and a tension spring (12). The gas combustion timing automatic turning-off apparatus is characterized in that the gas combustion timing automatic turning-off apparatus is also provided with an action press plate (9) which is a metal plate whose one side is curved into a closed circular pipe (31) and the other side is curved into one side of angle with 90 DEG-120 DEG and is fixed on the bottom plate of the timer. The lock pawl (6) is arranged between the disc and the action press plate and is positioned on the mounting plate by a screw (8). One end of the lock pawl is tightly pressed by a pressure spring (7), which makes one side angle of the lock pawl be positioned in the saw tooth groove of the disc. The other end of the lock pawl is connected with the action press plate (9). The utility model has the advantages of small size and high reliability. The gas combustion timing automatic turning-off apparatus is suitable for automatically turning off a gas range or a gas baking box by a timed mode.

Description

Gas combustion timing automatic turning-off apparatus

The utility model belongs to the device with mechanical system control burning, particularly adopts the device of timer control burning.

The Gas range timer of selling in the city is the disk that installation one has serrated slot on the gas-cooker valve rod mostly at present, utilizes existing timer repacking, adds a lock pawl between disk and timer.When timer moves, touch lock pawl and rotate, lock pawl leaves the serrated slot of disk, and disk rotates under extension spring drives, and closes the gas-cooker valve.Low, the poor reliability of existing Gas range timer sensitivity.

The purpose of this utility model provides a kind of sensitivity, reliable combustion gas regular automatical shutoff device.

The utility model is to realize like this, specific practice is: adorn a disk on the valve rod of gas-cooker, disk border is provided with serrated slot and circular hole, extension spring is housed on the circular hole, it can make disk rotate suitable angle, disk drives valve rod rotary closing valve, and disk is by the mechanical timer control that matches.

Below in conjunction with drawings and Examples the utility model is described in detail.

Referring to Fig. 1,2, the utility model is a kind of combustion gas regular automatical shutoff device, comprise buck plate (1), disk (2), disc holder (3), lock pawl (6), timer (11) and extension spring (12), disk is contained on the valve rod (4) of gas-cooker, locate with pin (5), disk border has serrated slot (14) and circular hole (15), extension spring (12) one ends insert in the circular hole (15), the other end is screwed on buck plate, it is characterized in that also being provided with action pressing plate (9), the action pressing plate is a metallic plate, roll to closed pipe (31) on one side, another side curves 90 °～hexagonal angle limit (32), is positioned on the timer base plate by rivet (30); Lock pawl (6) is located between disk and the action pressing plate, it is positioned on the buck plate by screw (8), one end of lock pawl is compressed by stage clip (7), and the corner, one side that makes lock pawl is in the serrated slot of disk, and the other end of lock pawl joins with action pressing plate (9); When timer moved, the action pressing plate moved down, and lock pawl serves as that axle rotates with screw (8), and the serrated slot of disk is thrown off in a corner of lock pawl, and extension spring this moment (12) pulling disk rotates, and disk drives the gas-cooker valve rod and rotates, and closes burnt gas valve.

Referring to Fig. 3, Fig. 4, disc holder (3) is a middle microscler angle Support that has circular hole (22), is screwed on buck plate, and forms a square space (13) between the buck plate, and disk (2) is talked about wherein.

Referring to Fig. 5, Fig. 6, disk (2) endoporus is provided with the internal spline (16) of 2 symmetries.

Referring to Fig. 7, Fig. 8, lock pawl (6) has the trapezoidal plate (18), spring (17) of slotted hole (19) by the middle part and is made up of the trapezoidal plate (20) of shearing, be bent into gathering sill (21), trapezoidal plate (18) inserts in the gathering sill (21) of trapezoidal plate (20), and can left and rightly move, spring (17) presses trapezoidal plate (18), and lock pawl is positioned on the buck plate with screw (8).

Use operation as follows: at first to rotate timer, timer escapement pressing plate (29) jack-up action this moment pressing plate (9), spring (7) is depressed lock pawl (6), make lock pawl press disk border, rotate the gas-cooker valve rod then, disk also rotates thereupon, when forwarding serrated slot and the lock pawl place that meets to, the corner, one side of lock pawl is gone in the serrated slot (14), promptly finishes regularly.When preset time arrives, this moment, timer escapement pressing plate was return, and action pressing plate (9) moves down, lock pawl serves as that axle rotates with screw (8), and serrated slot is thrown off in a corner of lock pawl, and extension spring this moment (12) pulling disk rotates, disk drives the rotation of gas-cooker valve rod, closes burnt gas valve (24).

Among Fig. 9～Figure 12, (23) are that burner for gas stove, (24) are valve rod knob for timing means outer cover, (27) for timer knob, (28) for electric igniter, (26) for valve, (25).

The utility model is simple in structure, be active in one's movements, safe and reliable, easy to use, be applicable to that the timing automatic of various gas-cookers, gas burning roastor close.
