Cash box with spring balance mechanism

Abstract

The invention relates to a spring force-balance mechanism for a cashbox. The spring force-balance mechanism comprises a box body and a carrying plate located in the box body, wherein two ends of the carrying plate are respectively and vertically connected with a first slide plate and a second slide plate; a supporting plate which is vertically arranged with the carrying plate, a first spring, a second spring, a third spring and a fourth spring are installed in the box body; a first guide wheel group and a second guide wheel group are respectively arranged at the upper end and the lower end of the supporting plate; one ends of the first spring and the second spring are connected to the first slide plate; one ends of the third spring and the fourth spring are connected to the second slide plate; the other ends of the first spring and the third spring are connected with the supporting plate after passing through parts of the first guide wheel group and the second guide wheel group; and the other ends of the second spring and the fourth spring are connected with the supporting plate after passing through the first guide wheel group and the second guide wheel group. The spring force-balance mechanism for the cashbox, disclosed by the invention, is simple in structure, capable of fully filling cash in the box body, large in space utilization rate, and constant in pushing force for pushing the cash.

Description

technical field [0001] The invention relates to a self-service device, in particular to a spring balance mechanism for a cash box. Background technique [0002] With the continuous development of science and technology, people's living standards are also developing rapidly. Therefore, many self-service devices have emerged as the times require. With the emergence of self-service equipment such as automatic vending machines and automatic ticket vending machines, banknotes are also more and more widely used on these equipment. With the wide application of banknotes in self-service equipment, the requirements for the reliability and maintainability of banknote processing devices in the self-service system are getting higher and higher. [0003] The cash box used to store banknotes is provided with a slidable supporting plate, and the lower end of the supporting plate is connected with a spring. The banknotes are pushed from the entrance of the front end of the cash box int...

Problems solved by technology

[0003] The cash box used to store banknotes is provided with a slidable supporting plate, and the lower end of the supporting plate is connected with a spring. The banknotes are pushed from the entrance of the front end of the cash box into the cash box by the driving force. When the banknotes are stacked more and more For a long time, it is easy to have the following defects: 1. Since the spring is compressed shorter and shorter, the upward elastic force generated by the spring on the supporting plate is getting bigger and bigger, so the driving force used to push the banknote needs to be bigger and bigger to resist The elastic force of the spring pushes the banknotes into the cash box; 2. When the spring is compressed to the shortest, the supporting plate is resisted by the spring at a certain position and can no longer move, and the space behind the supporting plate is wasted, making it used for storing banknotes The available space of the cash box is relatively small, wasting a lot of space resources, resulting in frequent and time-consuming removal of banknotes for new banknotes to enter the cash box
