Description
Technical field
The present invention relates to the auto-unlocking device of drawer in casher box.
Background technology
As everyone knows, in the market, the occasion such as supermarket, hotel, retail store is widely used cashier's machine and collects coin or bill.Present cashier's machine, usually all be provided with grab and the automatically-unhooked auto-unlocking device of spacer pin on the casing that lays respectively at drawer, its structure generally includes: be arranged on the base plate on casing, be provided with electromagnet on base plate, be movably set with iron core in electromagnet, the end of iron core is for being used for rushing open the impact head of grab.In actual use, the less stable of this auto-unlocking device often can cause drawer to open.
Summary of the invention
Technical problem to be solved by this invention is: the auto-unlocking device that a kind of reliable and stable drawer in casher box is provided.
for solving the problems of the technologies described above, the technical solution used in the present invention is: the auto-unlocking device of drawer in casher box, comprise: casing and the base plate that is arranged on casing, be provided with electromagnet on base plate, be movably set with iron core in electromagnet, be provided with back-up ring on iron core, iron core is set with back-moving spring in the inboard of back-up ring, iron core offers the strip tie rod hole in the outside of back-up ring, also be provided with rotational pin on described base plate, be movably set with the swing sheet on rotational pin, the arranged outside that swings sheet is useful on the impact head of release, the two ends that swing sheet are respectively arranged with outwardly directed pull lever and gag lever post vertically downward, pull lever stretches in described tie rod hole, also be provided with the circular arc spacing hole on base plate, gag lever post stretches in spacing hole.
Described swing sheet, pull lever, impact head and gag lever post are the integral type structure.
The invention has the beneficial effects as follows: the present invention has increased back-up ring on iron core, and be provided with back-moving spring between iron core and electromagnet, grab is clashed into by swing mechanism in the end of iron core, and the motion of swing mechanism is subject to the restriction of spacing hole, and its running orbit is very steady.So just make whole auto-unlocking device reliable and stable.

The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As depicted in figs. 1 and 2, the auto-unlocking device of drawer in casher box of the present invention, comprise: casing and the base plate 1 that is arranged on casing, be provided with electromagnet 2 on base plate 1, be movably set with iron core 3 in electromagnet 2, be provided with back-up ring 31 on iron core 3, iron core 3 is set with back-moving spring 4 in the inboard of back-up ring 31, iron core 3 offers the strip tie rod hole in the outside of back-up ring 31, as shown in Figure 5, this tie rod hole is made of the U-shaped groove 32 that is opened in iron core 3 outside end faces and the bearing pin 7 that is located in the pin-and-hole 33 of U-shaped groove both sides sidewall; Also be provided with rotational pin 5 on described base plate 1, as shown in Figure 3 and Figure 4, the arranged outside that swings sheet 6 is useful on the impact head 62 of release, the two ends that swing sheet 6 are respectively arranged with outwardly directed pull lever 61 and gag lever post vertically downward 63, swinging sheet 6, pull lever 61, impact head 62 and gag lever post 63 is the integral type structure, pull lever 61 stretches in described tie rod hole, also be provided with circular arc spacing hole 11 on base plate 1---shown in Figure 2, gag lever post 63 stretches in spacing hole 11, and described rotational pin 5 is movably arranged in the rotating hole 64 that swings on sheet 6.Also be provided with spacer pin 8 on base plate 1, an end of spacer pin 8 is provided with the pin cap, and the other end is provided with cottor pin 9.
Operating principle of the present invention is: when electromagnet 2 is not worked, iron core 3 can be under the effect of reseting pressuring spring 4, and pull lever 61 can be pushed in the bottom of U-shaped groove 32, and swinging sheet 6 can turn clockwise around rotational pin 5, until gag lever post 63 is obstructed, keep static balancing in spacing hole 11; During drawing-out type drawer, 50 milliseconds of left and right of electromagnet 2 energising, the coil in electromagnet 2 produces moment magnetic force, and the suction that iron core 3 is produced overcomes the elastic force of reseting pressuring spring 4, like this, pull lever 61 just follows iron core 3 to retraction, makes swing sheet 6 rotate counterclockwise around rotational pin 5, swings sheet 6 in rotation process, the grab of impact head 62 meeting hit cards on spacer pin 8, grab is outwards rotated, and slippage from the spacer pin 8 realizes automatic unlocking; Then, under the effect of ejecting mechanism, drawer is opened.Electromagnet 2 energisings finish, and swing sheet 6 and can under the effect of reseting pressuring spring 8, return to original position again.
