There are many types of cash-dispensing gates for single ATMs in the industry, including up-and-down movable ones and internal rotating ones, while the cash-dispensing gates for ATMs are mainly flat-push ones. The disadvantage of the horizontal push gate is that it needs to take up a lot of space. Therefore, in order to save space, the applicant wishes to apply the rotary gate to the deposit and withdrawal ATM machine. However, the self-locking mechanism of the existing rotary gate has complex structure, high cost and low reliability.

detailed description

(Example 1)

Referring to Fig. 1 to Fig. 4, the self-locking mechanism of the rotary gate in this embodiment includes a support 1, an electromagnet 2, a guiding structure 3, a rotating bracket 4, a travel switch 5 and a tension spring.

The electromagnet 2 is fixed on the support 1. The guide structure 3 is horizontally slidably connected with the support 1 and driven by the electromagnet 2 to move. The guide structure 3 includes an iron core 31 , a guide pin 32 and a guide bracket 33 . One end of the electromagnet 2 is provided with a blind hole. One end of the iron core 31 is slidingly connected with the blind hole of the electromagnet 2 . One end of the guide bracket 33 is rotatably connected with the bottom of the rotating bracket 4 . The other end of the iron core 31 is fixedly connected with the other end of the guide bracket 33 through the guide fixing pin 32 . The support 1 is provided with a long hole, and the guide pin 32 is slidingly connected with the long hole on the support 1 .

The middle part of the rotating bracket 4 is rotatably connected with the support 1 , and the top of the rotating bracket 4 is provided with a bayonet that can cooperate with the top of the gate driving part 6 . The gate driver 6 is used to drive the rotary gate to rotate. Both ends of the extension spring are connected with the support 1 and the guide structure 3 respectively. The direction of the force exerted by the extension spring on the guide structure 3 is opposite to the direction of the force exerted by the electromagnet 2 on the guide structure 3 after the electromagnet 2 is energized. The travel switch 5 is fixed on the support 1 and cooperates with the guide bracket 33 of the guide structure 3 . Travel switch 5 adopts groove type photoelectric switch.

When the electromagnet 2 is energized, the guide structure 3 will drive the rotating bracket 4 to rotate clockwise against the tension of the extension spring. At this time, the gate driver 6 is in an open state, and can rotate counterclockwise to cross the bayonet on the rotating bracket 4 . After the electromagnet 2 is powered off, the rotating bracket 4 returns to the initial position. If the gate driving part 6 is to be closed, it only needs to be driven by an external force and rotate clockwise, and the mating surface of the gate driving part 6 crosses the bayonet on the rotating bracket 4 , the self-locking state can be achieved.

The specific embodiments described above have further described the purpose, technical solutions and beneficial effects of the present utility model in detail. It should be understood that the above descriptions are only specific embodiments of the present utility model and are not intended to limit the present invention. For the utility model, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
