Description

Technical Field

[0001] The present invention relates to the technical field of commercial office furniture, and in particular to a cash register that is easy to store, saves space, and is convenient for transportation. Background Art

[0002] A cash register is an indispensable facility in shopping malls, stores, and supermarkets. It is a place where customers settle their goods. It usually includes a main unit, a QR code scanner, a receipt printer, and two screens, one facing the cashier and the other facing the customer.

[0003] Existing cash registers are often set as all-in-one machines, with the screen and the main unit being an integrated structure. The advantage is that it reduces the number of external wires, making the cash register neat and safe. However, this will affect transportation and storage because the structure of the all-in-one machine is special and requires a large space, making it inconvenient for transportation and storage. Summary of the Invention

[0004] The present invention provides a cash register that is easy to store, saves space, and is convenient for transportation, which has the characteristics of being separable, easy to store, not occupying space, and convenient for transportation.

[0005] The above object of the present invention is achieved by the following technical solutions:

[0006] A cash register that is easy to store, saves space, and is convenient for transportation, including a main unit, characterized in that: it further includes a first screen, a second screen, and a connecting column;

[0007] One end of the connecting column is inserted into the first screen, and the other end is inserted into the main unit; the second screen is in concave-convex fit with the main unit.

[0008] By adopting the above technical solution, during storage and transportation, the connecting column can be detached from the main unit, and the first screen can be detached from the connecting column. In this way, during storage or transportation, it can be stored in parts, saving space compared to an all-in-one machine, and is easy to install; during use, it can be quickly assembled without affecting normal use.

[0009] Further, a first plug is provided at the top end of the connecting column. One end of the first plug is inserted into the connecting column, and the other end is a cylindrical end; a connecting seat matching the shape of the cylindrical end is provided on the back side of the first screen.

[0010] By adopting the above technical solution, the first plug is used to connect the connecting column and the first screen. During disassembly, the first screen can be directly removed from the connecting column, which is convenient for disassembly.

[0011] Further, a hole is provided on the side wall of the connecting seat. A nail is provided in the hole and extends out of the inner side of the connecting seat. A straight groove matching the nail is provided along the radial direction on the side surface of the cylindrical end. The top end of the straight groove communicates with the top end of the cylindrical end, and the bottom end of the straight groove extends along the circumferential direction of the cylindrical end to form a circumferential groove surrounding the circumferential side of the cylindrical end.

[0012] By adopting the above technical solution, first drive a plug pin into the connecting seat, then insert the connecting seat onto the cylindrical end, and align the end of the plug pin extending out of the connecting seat with the straight groove. After the end of the plug pin moves to the bottom end of the straight groove, rotate the first screen so that the end of the plug pin is located in the circumferential groove, thereby fixing the first screen and the connecting column in the vertical direction. When disassembling, reverse the above process to disassemble the first screen from the connecting column.

[0013] Furthermore, two relief grooves one are provided along the radial direction on the side wall of one end of the first plug inserted into the connecting column. The relief grooves one are arranged along the diagonal of this end, and a strip-shaped end corresponding to the position, shape, and size of the relief grooves one is provided inside the top end of the connecting column.

[0014] By adopting the above technical solution, after the cooperation between the relief grooves one and the strip-shaped end, the connection strength between the first plug and the connecting column can be enhanced.

[0015] Furthermore, a plug pin is also provided on the side wall of one end of the first plug inserted into the connecting column, and a matching hole is provided at the corresponding position at the top end of the connecting column.

[0016] By adopting the above technical solution, when the first plug is inserted into the top end of the connecting column, the plug pin can be inserted into the hole at the top end of the connecting column, which can enhance the connection strength between the first plug and the connecting column and provide strong support for the first screen.

[0017] Furthermore, a second plug is provided at the bottom end of the connecting column. There are two holes on the second plug, and the positions of these holes correspond to the two strip-shaped ends respectively. An assembly end matching the bottom end of the connecting column is provided on the host, and two protrusions matching the holes are provided inside the assembly end.

[0018] By adopting the above technical solution, by using the second plug, two holes are provided at the bottom end of the connecting column. After the bottom end of the connecting column is inserted into the assembly end on the host, the protrusions can be inserted into the holes, strengthening the stability of the connecting column in the assembly end, so that the first screen can be indirectly installed on the host. When disassembling, just pull out the connecting column from the assembly end.

[0019] Furthermore, an annular flange is provided on the circumferential side of the assembly end, and the annular flange is fixedly arranged inside the top end of the host.

[0020] By adopting the above technical solution, using the annular flange to fix the assembly end inside the top end of the host can strengthen the stability of the assembly end on the host and avoid the instability of the connecting column and the first screen caused by the instability of the assembly end.

[0021] Furthermore, a transmission socket is also provided inside the assembly end, and a transmission plug is also provided inside the second plug.

[0022] By adopting the above technical solution, after the connecting column is inserted into the assembly end and the transmission plug is inserted into the transmission socket, the host can be connected to Screen 1, avoiding excessive wiring for Screen 1.

[0023] Furthermore, there are multiple bumps on the host, and there are multiple holes at the bottom of Screen 2 that match the bumps; there is a hole in the middle of the bump, and there is also a corresponding hole at the bottom of Screen 2.

[0024] By adopting the above technical solution, Screen 2 can be fixed on the host by using the bumps. When disassembling, Screen 2 can be directly removed from the host, which is convenient for disassembly and installation.

[0025] Furthermore, the whole cash register also includes a keyboard, a receipt printer, a QR code scanner, and a cash register box.

[0026] By adopting the above technical solution, the keyboard, the receipt printer, the QR code scanner, and the cash register box are all devices externally connected to the host. They can be disassembled and stored separately during storage and transportation, and then installed during use.

[0027] In summary, the beneficial effects of the present invention are as follows: During storage and transportation, the connecting column can be removed from the host, and Screen 1 can be removed from the connecting column. In this way, during storage or transportation, it can be stored in parts, saving space compared to an all-in-one machine, and it is convenient for installation. During use, it can be quickly assembled without affecting normal use; 2. Screen 2 can also be removed from the host, which is convenient for storage. BRIEF DESCRIPTION OF THE DRAWINGS
