Background technology
Self-help terminal equipment is provided with gate usually.Such as the cash dispensing port place of self-help drawing money machine arranges gate, banknote is transported to cash dispensing port, and gate is opened, and waits for that the user takes banknote away, and through after the schedule time, gate seals cash dispensing port automatically; The ticket outlet of automatic machine is provided with gate, and ticket paper is transported to ticket outlet, and gate is opened, and waits for that the user takes ticket paper away, and through after the schedule time, gate seals ticket outlet automatically; The outlet of the self-service check treatment facility of Bank Hall setting is provided with gate, after completing the check processing, check is delivered to outlet, waits for that the user takes away, and through setting-up time, gate will export sealing automatically.
For fear of being clamped finger, come to harm by gate when the user getting thing, Chinese patent application CN201110007619.1 provides a kind of gate mechanism, and as shown in Figure 1, the gear train that drives the gate motion comprises pull bar 5 ', self-lock rod 6 ' and driving lever 7 '.Wherein, an end of pull bar 5 ' is provided with long slot bore 51 ', and long slot bore 51 ' coordinates with the eccentric part 41 ' socket of the driven unit 4 ' that drives the gate motion, and the other end of pull bar 5 ' is connected with the installation frame 1 ' elasticity of gate by the first flexible member 8 '; Self-lock rod 6 ' is by the installation frame 1 ' pivot joint of drive-connecting shaft 11 ' with gate, and the coupling shaft (not shown) on self-lock rod 6 ' is pegged graft with pull bar 5 ' and coordinated; Driving lever 7 ' and drive-connecting shaft 11 ' pivot joint, the one end is connected with installation frame 1 ' elasticity by the second flexible member 9 ', and the driving shaft 71 ' of driving lever 7 ' is connected with the gate (not shown).
When eccentric part 41 ' the driving pull bar 5 ' of driven unit 4 ' moves along direction initialization, driving self-lock rod 6 ' rotates along direction initialization around drive-connecting shaft 11 ', the coupling shaft of self-lock rod 6 ' drives driving lever 7 ' and synchronously rotates around drive-connecting shaft 11 ', and the driving shaft 71 ' of driving lever 7 ' drives gate and opens cash dispensing port A; When the eccentric part 41 ' of driven unit 4 ' drove pull bar 5 ' and rotates along the reverse direction of direction initialization, driving lever 7 ' is driving gate sealing cash dispensing port A under the effect of the second flexible member 9 '.Because the acting force of gate sealing cash dispensing port is provided by the second flexible member 9 ', by reduce the elastic force of the second flexible member 9 ' as far as possible, when avoiding user's finger accidentally to be clipped to by gate 2 ', finger is caused too major injury.
The problem of this gate mechanism is, the keying of gate is by pull bar 5 ', self-lock rod 6 ', driving lever 7, two flexible members 8 ', a plurality of part transmissions such as 9 ', if the elastic force of the second flexible member 9 ' is too small, be difficult to guarantee that gate normally seals outlet, if the elastic force of the second flexible member 9 ' is larger, gate still can produce injury to finger when clipping to user's finger, therefore, this gate mechanism is complex structure not only, and the finger function is unreliable.
