The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.As shown in Figure 1, toaster base 1 of the present utility model tilts and is fixed with baking groove 29.As shown in Figure 2, the holder bar and first balladeur train 22 that stretch in the baking groove 29 are consolidated into one, form carriage mechanism, vertical shaft 32 passes the hole of first balladeur train 22, is slidingly connected with its formation, and second balladeur train 13 passes the vertical shaft 15 and vertical shaft 21 that is arranged in parallel, be slidingly connected with its formation, second balladeur train 13 is to first balladeur train, 22 extended cantilevers 16, and the elongated slot 28 by on first balladeur train 22 is supported under the boss of first balladeur train 22.Being connected with spring 18, the second balladeur trains 13 between first balladeur train 22 and second balladeur train 13 connects together by the upper hem of extension spring 19 with baking groove 29 preceding interior plates.Fixing rocking arm supporting base 2 on the base 1, Rocker arm 4 can be around axle 3 rotations by axle 3 hinged being loaded in the rocking arm supporting base 2.As shown in Figure 7, elongated slot 28 is arranged under the boss of first balladeur train 22.As shown in Figure 4 and Figure 5, rocking arm supporting base 2 by complete symmetry, have two element mountings that bayonet lock 30 and position, hole 33 can fasten and fasten and form, in the bayonet lock 30 corresponding positions, hole 33 of inserting on another on.The neck that vertically is provided with first adjutage 5 and second adjutage, 7, the first adjutages 5 on the Rocker arm 4 is a garden cylindricality 24, stretches in the triangle pilot hole 10 on second balladeur train 13, and forms and to be slidingly connected, and there is position-limited block 23 end of neck garden post 24.As shown in Figure 6, there is the slotted hole of prolongation on triangle pilot hole 10 triangle bases down along the base.As shown in Figure 3, be fixed with first hook 17 on first adjutage 5, first hook, 17 bottoms are provided with iron-absorbing base 26 and inhale retort stand 27, when retort stand 27 is inhaled in the coil adhesive of iron-absorbing base 26, inhale the hook-shaped position on retort stand 27 tops and block first hook 17, on the lower raft 1 of second adjutage 7 electric switch seat 8 is installed, electric switch seat 8 is provided with movable contact and fixed contact, be connected with steel wire 9 on the cantilever 20 that movable contact extends, second adjutage 7 is positioned on the elastic wire 9, the end of first adjutage 5 is provided with second hook, 14, the second balladeur trains, 13 upper ends and is provided with the 3rd hook 12, and extension spring 11 is connected between the 3rd hook 12 and second hook 14.The free-ended end 6 of Rocker arm 4 is connected with the outer flap hand 25 of machine.
The course of work is as follows: with rusk put into the baking groove 29 after, the outer flap hand 25 of the machine of pressing, flap hand-motion Rocker arm 4 rotates around axle 3; guide hole 10 of neck garden post 24 compressings second balladeur train 13 of first adjutage 5 of Rocker arm 4; it is descending along vertical shaft 15 and vertical shaft 21 to drive second balladeur train 13, and when second balladeur train 13 slided downwards, spring 18,19 was stretched; spring 18 back that is stretched drives first balladeur train 22 and slides downwards along vertical shaft 32, drive simultaneously holder bar and rusk in baking groove 29 to the next motion.Rocker arm 4 continues descending, the elastic wire 9 on the cantilever 20 of second adjutage, 7 compressing electric switch seats 8, and cantilever 20 is downward, makes the movable contact of electric switch seat 8 and fixed contact connect power on circuitry.At this moment the coil electricity of iron-absorbing base 26 produces magnetic force with position suction retort stand 27 absorption thereon, at this moment; the hook 17 on first adjutage 5 of Rocker arm 4; just be positioned at the bottom of inhaling retort stand 27 hook positions and be stuck; extension spring 11 is stretched, thereby hook 17 is locked; at this moment, baking groove 29 internal heat generation elements begin heating.
When the stoving time that reaches setting, control system is sent signal, cuts off circuit.Under the normal condition, the coil blackout of iron-absorbing base 26, suction disappears, and the suction retort stand 27 of absorption is released, and bound hook 17 is no longer restrained.Under the pulling force effect of spring 19, second balladeur train 13 upwards slides along vertical shaft 15,21.At this moment, cantilever on second balladeur train 13 16 is the boss on jack-up first balladeur train 22 upwards, and first balladeur train 22 drives the holder bars and rusk slides to upper together, arrives uppermost position in fig-ure.
Because of cause specific, balladeur train or holder bar are stuck, or big because of the rusk size, when malposition causes carriage or balladeur train to be stuck, can't throw off with the coil of iron-absorbing base 2 owing to inhale retort stand 27, can not cut off the power supply, toast then that heating element heaters can continue heating in the groove 29.At this moment, the 3rd hook 17 is inhaled retort stand 27 and is blocked, then balladeur train 13 is stuck and can't moves up, under the effect of extension spring 11; first adjutage, the 5 neck garden posts 24 of Rocker arm 4 can upwards slide in the groove of the guide hole 10 of second balladeur train 13; Rocker arm 4 spring 11 pull-ups that are stretched; Rocker arm 4 and balladeur train 13 have produced relative displacement; Rocker arm 4 drives second adjutage 7 and moves upward simultaneously, and second adjutage 7 breaks away from elastic wires 9 and no longer oppresses elastic wire 9, and electric switch seat 8 cantilevers 20 are upturned; the movable contact on the switch base 8 then; fixed contact is thrown off; circuit is cut off, and baking groove 29 interior heating element heaters have stopped heating, have prevented the generation of accident.
