Description

Technical Field

[0001] The utility model relates to the technical field of POS machines, in particular to a handheld mobile cash register terminal printing device. Background Art

[0002] POS is a multifunctional handheld mobile terminal that can realize automatic electronic fund transfer. It supports consumption, pre-authorization, balance inquiry and transfer, and is safe, fast and reliable to use. POS reads the cardholder's magnetic stripe information on the bank card through the card reader. The POS operator enters the transaction amount, and the cardholder enters personal identification information, i.e. password. POS sends this information to the issuing bank system through the UnionPay Center to complete the online transaction, give information on success or failure, and print the corresponding receipt. The application of POS realizes online consumption of bank cards such as credit cards and debit cards, ensures the safety, speed and accuracy of transactions, avoids the complicated labor of manual blacklist query and order suppression, and improves work efficiency.

[0003] The existing equipment is inconvenient to install the printing paper, and the end of the printing paper needs to pass through the narrow roller gap of the printing module, which has low installation efficiency.

[0004] The existing Chinese patent with the announcement number CN206819484U discloses a sliding loading and unloading printing paper POS machine, including a main shell part, a sub-shell part and an electronic part. The main shell part and the sub-shell part can be relatively slidably connected. A winding chamber for accommodating printing paper is arranged between the main shell part and the sub-shell part. The electronic part is arranged on the main shell part and the sub-shell part. The main shell part includes a handheld shell part and a sliding seat ear.

[0005] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the device fixes the two main shell parts and the sub-shell parts together through magnet adsorption, and when the POS machine falls or is hit, the impact force generated has a probability of opening the sub-shell part, causing the printed paper to fall off, and improvement is needed; therefore, a handheld mobile cash register terminal printing device is proposed to address the above problems. Utility Model Content

Compared with the prior art, it can effectively prevent the sub-shell from being accidentally opened. When in use, the limit frame is pulled outward and rotated to separate it from the sub-shell body, so that the sub-shell can be quickly opened, and quick separation is achieved, which is convenient for installing printing paper.

[0008] Preferably, the limiting protrusion is coaxially arranged with the connecting groove, and the limiting protrusion is fixedly mounted on the surface of the main shell, and the rotation angle of the limiting frame is limited by the limiting protrusion, so that the limiting frame presses against the limiting protrusion so that the card block automatically aligns with the card slot, which is convenient for connection.

When installing the printing paper, the printing paper is placed between the two clamps, so that the clamps are pressed against the printing paper through the tension of the springs, which can effectively prevent the printing paper from loosening.

[0014] Preferably, both sides of the clamping plate protrude outward to form limiting layers, and the distance between the limiting layers is slightly greater than the length of the printing paper, and the limiting layers limit the two ends of the printing paper.

[0015] Preferably, the surface of the clamp is rotatably connected to a plurality of conveying cylinders, and the conveying cylinders penetrate the limiting layer. When the clamp clamps the printing paper, the friction with the printing paper is reduced by the conveying cylinders to avoid excessive clamping force affecting the smoothness of paper feeding.

The electronic part includes a touch display screen, an earphone socket, a card reader, a printing module, a memory, a battery, a wireless connection module, a timer and a processor. The bottom ends of the main shell 1 and the sub-shell 2 are hinged. A winding chamber 5 for accommodating printing paper is arranged between the main shell 1 and the sub-shell 2. Conveying rollers for driving the printing paper to move are respectively arranged on the main shell 1 and the sub-shell 2 on both sides of the winding chamber 5. A limiting component 4 is installed on the surface of the main shell 1. The limiting component 4 includes a connecting groove 41 and an arc-shaped limiting protrusion 46. The connecting groove 41 is opened on the surface of the main shell 1, and the interior of the connecting groove 41 is slidably connected with Slider 42, one end of the slider 42 opposite to the connecting groove 41 is fixedly connected with a tension spring 43, and the other end of the slider 42 is rotatably connected to a limit frame 44, and a clamping block 45 is fixedly connected to the surface of the limit frame 44. A plurality of clamping grooves 7 are arranged on the surface of the main shell 1 and on the rotation track of the clamping block 45. By rotating the limit frame 44 to the corresponding position, the clamping block 45 is inserted into the inside of the clamping groove 7 through the tension of the tension spring 43, and then the position of the limit frame 44 is fixed, so that the limit frame 44 clamps the column sub-shell 2. Compared with the prior art, it can effectively prevent the sub-shell 2 from being accidentally opened. When in use, the limit frame 44 is pulled outward and rotated to separate it from the sub-shell, so that the sub-shell 2 can be quickly opened, and quick separation is achieved, which is convenient for installing printing paper.

[0029] The limiting protrusion 46 is coaxially arranged with the connecting groove 41 and is fixedly mounted on the surface of the main shell 1. The limiting protrusion 46 limits the rotation angle of the limiting frame 44 so that the limiting frame 44 abuts against the limiting protrusion 46, and the clamping block 45 automatically aligns with the clamping groove 7 for easy connection.

[0031] The printing mold is located on one side of the winding chamber 5.

[0032] The card reader is located on the main housing 1 .

[0033] Embodiment 2

[0034] For comparison with Example 1, please refer to Figure 5 As shown, the utility model provides another embodiment, a printing paper anti-loosening component 6 is installed inside the winding chamber 5, and the printing paper anti-loosening component 6 includes a plurality of slide grooves 61, and the slide grooves 61 are opened on the side wall of the winding chamber 5.

[0035] The printing paper anti-loosening component 6 also includes two arc-shaped clamps 62, both ends of the clamps 62 are slidably connected to the adjacent slide grooves 61, and both ends of the clamps 62 are fixedly connected with springs 63, and the other end of the spring 63 is fixedly installed on the side wall of the slide groove 61. When installing the printing paper, the printing paper is placed between the two clamps 62, so that the clamps 62 are pressed against the printing paper through the tension of the springs 63, which can effectively prevent the printing paper from loosening.

[0036] Both sides of the clamping plate 62 protrude outward to form limiting layers 64 , and the distance between the limiting layers 64 is slightly greater than the length of the printing paper. The limiting layers 64 limit the two ends of the printing paper.

[0037] The surface of the clamping plate 62 is rotatably connected to a plurality of conveying cylinders 65, and the conveying cylinders 65 penetrate the limiting layer 64. When the clamping plate 62 clamps the printing paper, the friction with the printing paper is reduced through the conveying cylinders 65 to avoid excessive clamping force affecting the smoothness of paper feeding.

[0038] It is worth noting that: since the handheld mobile cashier terminal printing device in this solution has the same components as those of the existing handheld mobile cashier terminal printing device, this solution does not describe all the existing components, but only describes some improved parts.
