Locking limiting device for value card hopper baffle plate

Abstract

The invention discloses a locking limiting device for a value card hopper baffle plate, and the device comprises a stepping motor, a limiting rod, a limiting sleeve, a value card hopper rotating shaft, a first sensor, a second sensor, an installation rack, and a limiting rack, wherein the stepping motor, the limiting rack and the first sensor are fixed on the installation rack. The second sensor is fixed at the upper end of the limiting rack. An output shaft of the stepping motor is fixed with the limiting rod, and the limiting sleeve is disposed on the limiting rod in a sleeve manner. The value card hopper rotating shaft is provided with a gap. When the stepping motor receives an electric signal, the stepping motor rotates through a certain angle, and the limiting sleeve will be clamped in the gap of the value card hopper rotating shaft, thereby achieving the purpose of locking the rotating shaft. The arrangement of the limiting rod enables the motor not to withstand a radial force during locking, thereby prolonging the service life of the motor, enabling the device to be simple and practical in structure, to be convenient for maintenance, to be long in service life, and to be low in cost.

Description

technical field [0001] The invention relates to the technical field of rail transit equipment, in particular to a locking and limiting device for a stored-value card bucket baffle. Background technique [0002] With the acceleration of the urbanization process, the traffic problem in the city has become a major issue that people pay attention to. At present, due to the increase in the number of private cars in the city, traffic congestion is becoming more and more serious. Therefore, the development of urban public transportation has become a trend, and rail transit (subway) is becoming increasingly popular due to its fast, convenient, and convenient travel. Preferred urban public transport. [0003] The subway traffic in major cities is large, and the waiting time for buying tickets is long. The emergence of automatic ticket exchange machines can greatly shorten the queuing time. In order to make better use of the ticket exchange machines, the ticket exchange machines have...

Problems solved by technology

[0003] The subway traffic in major cities is large, and the waiting time for buying tickets is long. The emergence of automatic ticket exchange machines can greatly shorten the queuing time. In order to make better use of the ticket exchange machines, the ticket exchange machines have also added a recharge function. The entry of other things in the process, so the locking device of the stored value card bucket is added, but when the device is locked, due to the external force, the stepper motor shaft will be subjected to radial force. In order to reduce this radial force, the current device Most of the solutions are to add a pair of bearings and a coupling, which greatly increases the cost and space

That is, although there are many locking devices at present, the cost is high; or the shaft of the stepping motor is often stressed, which shortens the life of the motor; or the device is cumbersome, resulting in cumbersome maintenance and increasing maintenance costs.
