The utility model advantage is compared with the existing technology: 1 can spiral-lock connect fast without flexible circuit conductor.2 use voltage lower.3 structures are simpler.4 visual effect are good.
Accompanying drawing explanation
Fig. 1 is a kind of double buckle low-voltage electric bell teaching mode embodiment.
Fig. 2 is embodiment schematic bottom view.
Embodiment
Below in conjunction with embodiment and accompanying drawing, describe a kind of double buckle low-voltage electric bell teaching mode of the present utility model in detail: Fig. 1 is a kind of double buckle low-voltage electric bell teaching mode embodiment: in Fig. 1,1 insulating base, 2 is fixed supports, and 3 is elastic sheet metals, and 41 and 42 is metal sub-buckles, 5 is connect wire, and 6 is adjustment screws, and 7 is springs, 8 is supports, and 9 is Title iron, and 10 is hand hammers, 11 is bell shelves, 12 is coils, and 13 is coil racks, and 14 is U-iron cores.
Fig. 2 is embodiment schematic bottom view: in Fig. 2, and 15 is bottoms, and 16 is apertures, and 17 is metal boxes.
In a kind of double buckle low-voltage electric bell teaching mode embodiment of Fig. 1, when wanting to use electric bell, first two of electric bell electrode leading-out terminals [corresponding metal sub-buckle 41 and 42] are connected with power supply, power supply is entered by metal sub-buckle 41, adjustment screw 6 is arrived again through connecting wire 5, contact with elastic sheet metal 3 again, then be communicated with wherein one end of coil 12, Gua mono-end of coil 12 is connected on metal sublayer and buckles on 42 and with another pole of power supply and connect, now, power supply connected by electric bell, the electromagnet be made up of coil 12 and U-iron core 14 can produce magnetic field, Title iron 9 is inhaled to the left side, drive hand hammer 10 simultaneously to left movement, bell shelves 11 are beaten, due to elastic sheet metal 3 can be driven when Title iron 9 moves to the left side also to left movement simultaneously, elastic sheet metal 3 is after left movement, elastic sheet metal 3 is caused to separate with adjustment screw 6, cause power supply brief interruption, the electromagnet be made up of coil 12 and U-iron core 14 can lose magnetic field, Title iron 9 and elastic sheet metal 3 move right by elastic force, elastic sheet metal 3 is allowed again to connect with adjustment screw 6, again switch on power, and repeat the above operating process having power supply, make Title iron 9 and endless the moving right of hand hammer 10 left, bell shelves 11 just ceaselessly sound.
