Description

Technical Field

[0001] The utility model relates to the technical field of banknote detectors, in particular to a banknote detector magnetic head convenient for maintenance. Background Technique

[0002] A banknote detector is a machine for verifying the authenticity of banknotes and counting the number of banknotes. Due to the large scale of cash circulation and the heavy workload of cash handling at bank teller counters, a banknote counting machine has become an indispensable device. The means of authenticity verification usually include fluorescence recognition, magnetic analysis, and infrared penetration. Portable banknote detectors are divided into two types: portable desktop laser banknote detectors and portable palm laser banknote detectors. Among them, banknote detectors using magnetic analysis means all use magnetic heads to distinguish the authenticity of banknotes.

[0003] However, the existing magnetic heads of banknote detectors are all fixedly connected to the banknote detectors by bolts. Therefore, when the banknote detector needs to be upgraded, it is very inconvenient for the staff to replace the magnetic head, which greatly reduces the convenience of the device.

[0004] For example, the Chinese patent discloses "A clamping structure of a banknote detector magnetic head", with the publication number: CN212569909U. This patent includes a banknote detector main body, a banknote inlet, a banknote outlet, and a detection component. An inlet for banknotes is opened on one side of the top of the banknote detector main body, and an outlet for banknotes is opened inside the banknote detector main body. The detection component consists of a mounting plate, a sensor, and a magnetic head. The mounting plate is installed on the outer wall of one side of the top of the banknote outlet. An installation groove is opened on the inner side of the bottom of the mounting plate. A sensor is arranged inside the installation groove, and connection grooves are arranged on both sides of the installation groove, and the connection grooves are opened on the inner side of the bottom of the mounting plate. The utility model fixes the magnetic head by means of snap connection, which facilitates the disassembly and replacement of the magnetic head by the user, thereby improving the convenience of the device. At the same time, the heat dissipation effect of the device during the use of the magnetic head is improved by the provided heat conduction sheet, heat conduction pipe, and heat dissipation fin, thereby ensuring the stability of the magnetic head during use.

[0005] However, this patent clamps and fixes the clamping block by the elasticity of the spring. After long-term use, the spring will have the phenomenon of metal fatigue, which will weaken its pressing force, causing the magnetic head to shake or even fall off, thus affecting the banknote verification work. Therefore, it is necessary to design a magnetic head that is convenient for disassembly and assembly and has a firm connection. Content of the Utility Model
