Description
Technical field
The utility model relates to the safe locking device of cooking apparatus, specifically refers to a kind of knob door lock that the fire door of domestic electric steaming furnace can be locked.
Background technology
Box domestic electric steaming furnace is to rely on the cooking equipment that high-temperature steam cooks food in the flue.Generally believed the trend that replaces micro-wave oven.But the electric steam furnace of present stage also exists the interior high-temperature steam of moment flue after the oven door opening can go out the hidden danger of scalding the person, and except being provided with at furnace roof the exhaust, safety valve, the fire door of electric steam furnace also all is provided with locking device simultaneously.But existing bolt-type fire door lock is fairly simple, and fire door closes not tightly, and steam is understood some leakage in use, and its main cause is that fire door is shut the back flue mouth is not produced thrust, the O-ring seal of fire door lid the inside and flue mouth press inadequately tightly due to.But if will make fire door lid and flue mouth press tightlyer, the lockhole that tends to cause locking bar and lock nose is difficult to aim at, so closing and opening of fire door all can some difficulty.In view of the foregoing, invent and a kind ofly press the fire door lid tighter, the electric steam furnace door lock seems necessary and open and close very flexibly.
The utility model content
The purpose of this utility model is: provide a kind of to the producer that produces electric steam furnace and close tightly, open and close the electric steam furnace fire door lock of flexible operation.
The technical scheme of the utility model technical solution problem is: a kind of electric steam furnace knob door lock, comprise lock arm, knob, locking bar and lock nose, described lock arm becomes to be horizontally disposed with, its outer end is connected by the rotary shaft hinge with electric steam furnace casing edge, at discoid rotatable fire door lid of the inboard connection in the stage casing of described lock arm, closely contact during described fire door cover closing with in the flue, be provided with the locking bar passage in the described lock arm in the middle of the section, described knob be located at lock arm in section surface, described knob is connected by cam pin with described lock arm, be provided with eccentric pin-and-hole at the position that described lock arm is covered by knob and insert the L shaped groove that driving lever needs, described L shaped groove is connected with a section middle locking bar passage in the lock arm.
The profile of described knob is the hemispherical of projection, and the centre is provided with the rectangle handgrip, and the hollow inwall of described knob is provided with one and is used for the recessed cover of described driving lever location and supplies knob self to rotate the cam pin of needs.
Described locking bar is that a cross section is oblate steel bar, is located in the locking bar passage of section intermediate lateral level in the described lock arm, and described locking bar end is provided with the pin-and-hole that inserts driving lever.
Described driving lever is located in the L shaped groove of section in the lock arm, one end of described driving lever is entangled by the recessed cover on the described knob internal chamber wall, the other end of described driving lever is inserted in described locking bar and the pin-and-hole driving lever link by L shaped groove, described driving lever can be pulled up and down or move left and right in L shaped groove, and the axis of described driving lever and described locking bar is orthogonal.
Described lock nose is one to be fixed on the bloom on the stove gate box body wall, is provided with oval-shaped lockhole in the middle of it, and the elliptic plane major radius of described lockhole is perpendicular to the ground.
The utility model is owing to the cross section with locking bar is designed to oblateness, and locking bar is when stretching into oval lockhole, and the major radius in the oblate cross section of locking bar is in position perpendicular to the ground, makes locking bar can insert oval-shaped lockhole smoothly, and feels flexibly easily.When locking bar is inserted into lockhole fully, because eccentric rotation in the knob, make driving lever pull locking bar, the major radius that locking bar is rotated to its oblate cross section is horizontal, the interior circle of the cylindrical of the major radius in this oblate cross section of hour locking lever and the short radius of oval lockhole is closely tangent, thereby locking bar is drawn closer together the lockhole inwall, make the fire door lid under the reaction force compressing of lock arm and locking bar, press tightlyer to the flue mouth.Therefore both solve the flexibility of unlatching, locking stove face plate period of the day from 11 p.m. to 1 a.m operation locking bar, solved the tight problem of sealing of locking back fire door lid again.

Fig. 2 is the enlarged drawing of circle part among Fig. 1;
Each several part title and mark among the figure: 1-casing, 2-lock arm, 3-fire door lid, 4-knob, 5-driving lever, 6-locking bar, 7-lock nose.
The specific embodiment
As depicted in figs. 1 and 2, the utility model is that a kind of domestic electric steaming furnace is closed the locking device that fire door is used, and it can close the fire door lid of electric steam furnace tighter.The knob door lock comprises lock arm 2, knob 4, locking bar 6 and lock nose 7.Lock arm is horizontally disposed with for 2 one-tenth, and its outer end is connected by the rotary shaft hinge with casing 1 edge.The stage casing of lock arm 2 is inboard to connect a discoid and rotatable fire door lid 3 so that with the interlock fastening of electric steam furnace flue edge, O-ring seal seals fire door lid and flue bead.The knob door lock be located at lock arm 2 in section, also be provided with the locking bar passage in the middle of the section in the lock arm 2.The bottom surface of knob 4 be fixed on lock arm 2 in section surface, lock arm 2 positions that cover at knob 4 are provided with L shaped groove and eccentric pivot hole, the locking bar passage in the middle of 2 li sections of L shaped groove and lock arm is connected.The outer surface of knob 4 is provided with the rectangle handgrip of projection, and the internal chamber wall of knob 4 is provided with a recessed cover and a knob 4 that is used for driving lever 5 location and self rotates the cam pin of needs.Locking bar 6 is that a cross section is oblate steel bar, is located in the locking bar passage of 2 li section intermediate lateral of lock arm level.One end of driving lever 5 is entangled by the recessed cover of knob 4 internal chamber walls, and the other end is inserted in the pin-and-hole of locking bar 6 ends by the L shaped groove on the lock arm 2, and driving lever 5 is orthogonal with the axis of locking bar 6.Lock nose 7 is one to be fixed on the bloom on casing 1 one sidewalls, is provided with oval-shaped lockhole in the middle of it.
The utility model is being closed the stove face plate period of the day from 11 p.m. to 1 a.m, catch rectangle handgrip on the knob 4 with hand, knob 4 is turned clockwise, knob 4 is that the axle center is reversed as off-centre with the cam pin in its inner chamber, the driving lever 5 that is entangled by the recessed cover of knob 4 inwalls promotes the lockhole direction motion of locking bar 6 to lock nose 7, locking bar 6 is when just stretching into lockhole, locking bar 6 is just made the rectilinear motion of translation along L shaped groove, because the oblate cross section major radius of this hour locking lever 6 is in the upright position, make locking bar 6 can insert in the lockhole of ovalize smoothly, when locking bar 6 is inserted into lockhole fully, the off-centre of knob 4 is reversed and is pulled driving lever 5 by recessed cover and move downward, driving lever 5 is stirred locking bar 6 along its axis half-twist, make the major radius in locking bar 6 oblate cross sections rotate to horizontal level, thereby make 6 pairs of lockhole elliptic planes of locking bar short radius inwall lean on tightlyer, make fire door lid 3 press closelyr at following O-ring seal of flue mouth of reaction force compressing of lock arm 2 and locking bar 6.When opening fire door, knob 4 is rotated counterclockwise, locking bar 6 rotates to its oblate major radius position perpendicular to the ground under driving lever 5 is pulled, continue turn knob 4, driving lever 5 moves backward, locking bar 6 withdraws from the lockhole in the middle of the lock nose 7 like a cork along the locking bar passage under driving lever 5 drives, fire door can be opened gently.
