Description

The fixture of gas combustion range ignition pin

Technical field

The utility model relates to the fixture in a kind of gas-cooker, particularly relates to the fixture of igniting pin in a kind of gas-cooker.

Background technology

Existing gas kitchen ranges mainly adopts install combustion device panel on the gas kitchen ranges chassis, install combustion device in the gas kitchen ranges chassis, and at burner installed inside thermocouple sensor and igniting pin, the igniting pin connects the knob knob by lead and connects gas nozzle.The installation of igniting pin relies on jump ring or split washer to fix usually, as Chinese patent CN2479365Y disclosed " a kind of burner of gas-cooker ", in this burner, the igniting pin of the gap between inside and outside distributor is installed on the burner by devices such as split washers exactly.But the required precision of the fixing device for installing of such igniting pin processing is higher, jump ring or split washer will be complementary with igniting pin size and closely cooperate with the installation site, if machining accuracy will produce the loosening of igniting pin inadequately or can't install and influence use, and also more complicated is installed, back of long duration has influence on the service life of burner and the serviceability of burner along with becoming flexible also can appear in the wearing and tearing of jump ring or split washer or the aging igniting pin that gets rusty.

The utility model content

Technical problem to be solved in the utility model is to provide at above-mentioned prior art present situation that a kind of requirement on machining accuracy is low, installation and simple for production, and the igniting pin igniting needle fixation device in service life that can extend.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of fixture of gas combustion range ignition pin, comprise burner, igniting pin, it is characterized in that: also comprise a spring, described igniting pin top has bulge loop, the bottom has draw-in groove, described igniting pin inserts on the burner in the corresponding installing hole and described bulge loop is stuck in the upper surface of installing hole, described spring is placed in the described igniting pin outside, the bottom of described spring is stuck in the described draw-in groove, and the lower surface that the upper end of described spring is butted on installing hole makes the igniting needle set that downtrend be arranged.By such igniting needle fixation device, the igniting pin can be installed in the installing hole of burner, and this fixture requirement on machining accuracy is not expensive also low, be convenient to produce and install.

Preferably, described spring is spiral helicine spring, and the diameter of this spring last lap is less than the diameter of multi-turn before, and also less than the external diameter of described draw-in groove.

Compared with prior art, advantage of the present utility model is the fixture of this igniting pin owing to used spring, so its processing is easy and requirement on machining accuracy is not high, the compensation in space, the service life of improving the igniting pin, the speed that can also accelerate to process and install reduces the cost of product between not only can realizing igniting pin and burner in long-term the use.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Fig. 1 is the structure cutaway view of the utility model burner for gas stove, has on the burner 1 of this burner for gas stove and igniting pin 2 corresponding installing holes 3, and igniting pin 2 inserts on the burners 1 in the installing hole 3, and fixes by spring 4.

Igniting pin 2 structures as shown in Figure 4, igniting pin 2 tops have with burner 1 on installing hole 3 corresponding bulge loops 21, the diameter of bulge loop 21 is greater than installing hole 3, therefore after igniting pin 2 inserts installing hole 3, this bulge loop 21 just in time is stuck in the upper surface of installing hole 3, makes igniting pin 2 be located in the installing hole 3 and can not drop downwards.Igniting pin 2 also has around the draw-in groove 22 of its surface one circle, and this draw-in groove 22 is positioned at the below of bulge loop 21, and the external diameter of draw-in groove 22 is less than the external diameter of igniting pin 2, and after igniting pin 2 was fit into installing hole 3 on the burner 1, draw-in groove 22 was positioned at installing hole 3 bottoms of burner 1.Spring 4 is installed on the outside that is placed in igniting pin 2 between the lower surface of the installing hole 3 on draw-in groove 22 and the burner 1, fixes by the snap action of draw-in groove 22 and the spring 4 bottoms pin 2 of will light a fire.

Particularly, shown in Fig. 2-3, described spring 4 is a helical spring, the diameter of one circle of the end of its medi-spring 4 is less than the diameter of top multi-turn, and the diameter of last lap is slightly less than the diameter of the draw-in groove 22 in the igniting pin 2, and the diameter of spring 4 other multi-turns is complementary with the external diameter of igniting pin 2, therefore, spring 4 can be centered around the periphery of igniting pin 2, and the last lap of spring 4 just in time can be stuck in the draw-in groove 22, so spring 4 can be fixed between the lower surface of installing hole 3 of draw-in groove 22 and burner 1.Because spring 4 lower ends are stuck in draw-in groove 22, the upper end is butted on the lower surface of installing hole 3, elastic force effect by spring 4, spring 4 can produce one tension force between the draw-in groove of the lower surface of installing hole 3 and the pin 2 of lighting a fire, feasible igniting pin 2 has downtrend and can not make progress from installing hole 3, because bulge loop 21 has limited the downward motion of igniting pin 2, and this spring 4 and bulge loop 21 just define the upper-lower position of igniting pin 2, the pin 2 of will lighting a fire is fixed in the installing hole 3 simultaneously.Because spring 4 itself just has elastic force, therefore the Working position of draw-in groove 22 also not necessarily will be fixed, upper-lower position have certain change all can, as long as the distance between draw-in groove 22 and installing hole 3 lower surfaces is less than the original length of spring 4, also require lower for the machining accuracy of draw-in groove 22.And increase along with service life, even generation space or draw-in groove 22 have produced wearing and tearing between the installing hole 3 on igniting pin 2 and the burner 1, because the effect of below spring 4, also can compensating with the elastic force of this space by spring 4, make igniting pin 2 can not be moved and become flexible with respect to burner, make the life-span of igniting pin 2 increase, and convenient the installation and processing.

Use such fixture, not only requirement on machining accuracy is not high, because the elasticity of spring itself makes the position of draw-in groove on the igniting pin have certain surplus, and the elastic force of this spring can also compensate because produce the space that wearing and tearing cause service time long afterwards, not only simple in structure, machining accuracy is low, and cost is also low, it is also easy in the extreme to install.

In addition to the implementation, the utility model also includes other embodiments, and the technical scheme that all employing equivalents or equivalent substitute mode form all should fall within the protection domain of the utility model claim.
