Description

Technical Field

[0001] The utility model relates to the technical field of currency detectors, in particular to a magnetic head for a currency detector with high stability. Background Art

[0002] A banknote counter is a machine that verifies the authenticity of banknotes and counts them. Due to the large scale of cash circulation and the heavy workload of bank tellers, banknote counters have become indispensable and frequently used equipment.

[0003] A row of rubber wheels is installed inside the upper cover of the money counter. The magnetic head is installed under the rubber wheels. It is a white metal object. The magnetic head is only connected to the rubber wheels by pins. It has poor stability and is prone to deviation or displacement, which reduces the accuracy of use. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a magnetic head for a currency detector with a simple structure, easy installation, and high stability, which is convenient for disassembly.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A highly stable magnetic head for a banknote detector includes a magnetic head body and a connecting frame, wherein a convex portion of the connecting frame is provided with a receiving groove, the inner wall of the receiving groove is contoured to the outer wall of the bottom of the magnetic head body, a first contact is provided at the bottom of the magnetic head body, a second contact is provided at a position corresponding to the first contact in the receiving groove, the second contact is connected to a pin outwardly, a positioning assembly is provided outwardly on the connecting frame, and a snap assembly is further provided between the magnetic head body and the connecting frame.

[0007] When in use, the connecting frame is installed in the printer, and the magnetic head body is inserted into the receiving slot of the connecting frame by plugging. During the process, the positioning component positions the plugging process. After the plugging is completed, the snap assembly connects the two. After the connection is completed, the first contact and the second contact are connected. This solution adds a connecting frame on the basis of the original connection only through pins, and places the magnetic head body in the receiving slot, which greatly improves the stability of the installation and sets a contact structure, which is convenient for disassembly during replacement and maintenance.

[0008] As an optimization, the positioning assembly includes a positioning block arranged on the side wall of the connecting frame, the positioning block is provided with a through hole, and the head body is provided with a pin, and the pin is arranged in cooperation with the positioning block.

[0009] In this way, during installation and replacement, positioning can be achieved quickly, which is convenient for installing the banknote detector in a narrow environment.

[0010] As an optimization, the snap assembly includes a U-shaped snap, the bottom surface of the U-shaped snap is contoured to the outer wall of the head body, the side wall of the connecting frame is provided with ridges, and the inner side wall of the end of the U-shaped snap is provided with a slot.

[0011] In this way, the U-shaped buckle can be quickly connected, and the cooperation between the buckle and the slot prevents separation, thereby achieving a stable connection between the magnetic head body and the connecting frame.

[0012] As an optimization, silicone is provided on the contact surface between the U-shaped buckle and the magnetic head body.

[0013] In this way, while reducing shock, the thickness is increased, and when the U-shaped buckle is assembled, the magnetic head body can be pressed tightly into the receiving groove to ensure that the first contact and the second contact are tightly fitted.

[0014] As an optimization, the bottom of the connecting frame is further provided with a support ear.

[0015] In this way, the mounting contact area is expanded, the shaking of the connecting frame and the magnetic head body caused by external contact is avoided, and the mounting stability is increased.

[0016] In summary, this solution has the advantages of simple structure, easy installation and easy disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention is further described in detail below with reference to the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional terms such as "upper, lower" and "top, bottom" are generally based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. Unless otherwise indicated, these directional terms do not indicate or imply that the devices or components referred to must have a specific direction or be constructed and operated in a specific direction, and therefore should not be understood as limiting the scope of protection of the present invention; the directional terms "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0021] like Figure 1-3As shown, a highly stable banknote detector magnetic head includes a magnetic head body 1 and a connecting frame 11, the connecting frame is protruded with a receiving groove 12, the inner wall of the receiving groove is contoured with the outer wall of the bottom of the magnetic head body, the bottom of the magnetic head body is provided with a first contact 13, the receiving groove is provided with a second contact 14 corresponding to the position of the first contact, the second contact is connected to the pin 15 outwardly, the connecting frame is provided with a positioning component outwardly, and a snap assembly is also provided between the magnetic head body and the connecting frame.

[0022] When in use, the connecting frame is installed in the printer, and the magnetic head body is inserted into the receiving slot of the connecting frame by plugging. During the process, the positioning component positions the plugging process. After the plugging is completed, the snap assembly connects the two. After the connection is completed, the first contact and the second contact are connected. This solution adds a connecting frame on the basis of the original connection only through pins, and places the magnetic head body in the receiving slot, which greatly improves the stability of the installation and sets a contact structure, which is convenient for disassembly during replacement and maintenance.
