Detailed description of the invention
Below, with reference to drawings and Examples, the utility model is described in detail:
As shown in Figure 1, a kind of electric cooker cover plate neglected loading self-checking unit, comprise the upper cover 1 fastened with electric cooker body and the cover plate 2 be inlaid in bottom upper cover 1, the hole 5 that is relatively fixed is formed in the cross bar 4 that upper cover 1 top is parallel to each other, outer wall cover has bearing pin 7 two ends of torsion spring 13 to be all attached in fixing hole 5 through the pin shaft hole 9 in buckle 8, extension spring 14 one end is connected with the fixing ear 6 on upper cover 1 top, and the other end is connected with the pilot hole 11 of buckle 8 upper end.
Upper cover 1 madial wall forms the limiting plate 15 of spacing torsion spring 13 long arm end.Be used for limiting the downward maximum position of rotation of torsion spring 13 long arm end, if the position that torsion spring 13 long arm end rotates is excessive, the position of first stirring torsion spring 13 with hand is also needed when installing cover plate 2, increase limiting plate 15 and avoid aforesaid operations, also can play the effect of axial limiting to torsion spring 13 simultaneously, when avoiding being dismounted for multiple times, torsion spring 13 produces excessive axial runout.
Buckle 8 top middle portion bends inwards to be formed and is convenient to the gripper shoe 12 of clamping torsion spring 13 galianconism end.The middle part of gripper shoe 12 forms strip slot, and the break width of arm end of width and the torsion spring 13 of strip slot is identical, realizes fixing of torsion spring 13 and buckle 8 by gripper shoe 12.Strip slot simultaneously in the middle part of gripper shoe 12 can also facilitate the dismounting of torsion spring 13.
Described buckle 8 lower end forms the longitudinal connecting plate 10 paralleled.Described buckle 8 is in undercut shape.Have certain gap between described connecting plate 10, connecting plate 10 can be avoided oversize and the integral layout that affects in upper cover 1, its free end of buckle 8 in undercut shape can realize the self-inspection of cover plate 2 when mobile by less movement.
Described connecting plate 10 movable end all bends inwards, and the kink of connecting plate 10 can increase connecting plate 10 and the contact area on pot body top in process of self-test, avoids the rigid shock to face, pot body fixed end.
Described cover plate 2 lateral wall forms the pressing plate 3 corresponding with torsion spring 13 long arm end.In assembling process, pressing plate 3 presses torsion spring 13 long arm end.
Described bearing pin 7, buckle 8 are matched in clearance.Ensure that buckle 8 can rotating around bearing pin 7 compared with friction.
Described pilot hole 11 axis is higher than the axis of fixing hole 5.Thus make extension spring 14 that buckle 8 can be pulled to rotate along bearing pin 7.
As shown in Figure 2, as non-setting-in cover plate 2, extension spring 14 pulls buckle 8 top left, buckle 8 upper end turns left, the connecting plate 10 of buckle 8 bottom turns right, torsion spring 13 does not stress, and its long arm end contacts with limiting plate 15, and described connecting plate 10 movable end kink and the top of electric cooker body offset.If be namely non-setting-in cover plate 2 in upper cover 1, because the top of connecting plate 10 with electric cooker body offsets, upper cover 1 can not fasten with pot body.
As shown in Figure 3, cover plate 2 is installed, the pressing plate 3 of cover plate 2 lateral wall upwards presses torsion spring 13 long arm end, under the effect of torsion spring 13, plate 8 upper end turns right, thus makes extension spring 14 be in extended state, and the connecting plate 10 of buckle 8 bottom turns left, thus the top of connecting plate 10 movable end and electric cooker body is separated, upper cover 1 can be fastened to it electric cooker.
The utility model can be controlled by extension spring, the rotation direction of torsion spring to buckle, thus when making non-setting-in cover plate in upper cover, upper cover can not fasten with pot body, the utility model is convenient to install, reusing is strong, electric cooker can being avoided to work when leaking gas, improve the service life of control circuit and computer chip.Reusing is strong, and electric cooker can be avoided in the situation of gas leakage, can carry out boosting work down, the available protecting personal safety of user.
