AI Technical Summary
In existing cash registers, the circuit board, heat sink, and mounting base are integrated, making it inconvenient to replace or repair the circuit board and heat sink.
The circuit board and heat sink are designed to be detachably connected. The circuit board and heat sink are modularly independent through guide grooves and fasteners, allowing the circuit board and heat sink to slide on the outside of the body, avoiding integration with the mounting base.
It facilitates the replacement or repair of circuit boards and heat sinks, simplifying the maintenance process.

Abstract
Claims
1. A cash register comprising a body, a mounting seat, a heat dissipation fin and a circuit board, characterized in that, The back of the housing is provided with a connecting part, and a receiving groove is formed on the back of the connecting part. The bottom end of the receiving groove is an open end. Guide grooves are formed on opposite side walls inside the receiving groove, and the guide grooves are in communication with the open end. The mounting base is connected to the back of the connecting part, and the connection position of the mounting base and the connecting part is located above the receiving groove. The circuit board is detachably connected to the heat dissipation fins, and the circuit board is located in the receiving groove. Guide parts are provided on opposite sides of the heat dissipation fins, and the guide parts are slidably adapted to the guide grooves. The connecting part is detachably connected to the guide parts by fasteners inserted from the outside to the inside of the guide grooves. The heat dissipation fins can drive the circuit board to slide into or out of the receiving groove from the open end.
2. A cash register according to claim 1, wherein The inlet end of the guide groove is provided with a guide structure for guiding the guide part into the guide groove.
3. A cash register according to claim 1, wherein, The back of the connecting part is provided with a threaded hole that communicates with the guide groove at the position corresponding to the guide groove. The fastener is threadedly connected to the threaded hole and locks the guide part in the guide groove.
4. A cash register according to claim 1, wherein, A mounting groove is also provided on the back of the connecting part. The mounting groove is located above the receiving groove. A circuit conversion board is installed and fixed in the mounting groove. The circuit conversion board is controlled by the circuit board and serves as an interface bridge for connecting the circuit board and the electronic devices inside the machine body.
5. A cash register according to claim 4, wherein, The mounting slot has multiple wiring ports that communicate with the interior of the machine body.
6. A cash register according to claim 4, wherein, A connector through-hole is provided on the partition between the mounting slot and the receiving slot, and the connector through-hole connects the mounting slot and the receiving slot.
7. A cash register according to claim 4, wherein, The upper surface of the mounting groove is provided with fixing parts on opposite sides, and the fixing parts are detachably connected to the mounting base.
8. A cash register according to claim 1, wherein, The connecting part is also provided with a number of heat dissipation holes that communicate with the interior of the machine body.
9. A cash register according to claim 1, wherein, The connecting part is integrally connected to the body.
10. A cash register according to claim 4, wherein, A positioning post is provided at a diagonal position in the mounting slot, and a positioning hole is opened at a diagonal position on the circuit conversion board. The positioning post is adapted to the positioning hole.
