Description

Technical Field

[0001] This utility model relates to the field of POS machine technology, and more specifically, to a portable POS machine that is easy to maintain. Background Technology

[0002] With the rapid development of technology and the continuous innovation of business models, as well as the popularization of mobile payment and the rapid development of e-commerce, portable POS machines have been widely used in the market due to their small size, light weight, and flexible operation. POS machines have become an indispensable tool for modern commercial transactions. Due to the dense internal components of POS machines, the outer shell of POS machines is generally used for protection.

[0003] However, most POS machines have a unibody casing or a two-part casing secured with screws. The unibody casing of these machines is non-removable. While some screw-secured casings can be disassembled, the removable portion is relatively small. Even after disassembly, the remaining casing still obstructs internal electronic components, hindering easy disassembly and repair by technicians. This increases repair time and costs, and disrupts normal business operations. Therefore, we propose a portable POS machine that is easy to repair. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5This utility model provides a technical solution: a portable POS machine that is easy to maintain, including a POS machine body 1. The POS machine body 1 has an inner exposed chamber 10 with its top connected to the outside. End screw protrusions 11 are fixedly installed on the cavity walls at the two corners on the right side of the inner exposed chamber 10. A front exposed chamber 12 with its top connected to the outside is provided on the left side of the inner exposed chamber 10. Two symmetrical inclined slots 13 are provided on the bottom wall of the front exposed chamber 12. A top cover is provided on the top of the POS machine body 1. 2. A front cover plate 20 is fixedly installed on the left end of the top cover 2. The front cover plate 20 covers the front exposed chamber 12. Two symmetrical snap-fit ​​protrusions 21 are fixedly installed on the bottom surface of the front cover plate 20. The snap-fit ​​protrusions 21 are engaged with the inclined slots 13. The right end plate of the top cover 2 is fixedly connected to the end screw protrusion 11. The top cover 2 rests on the top surface of the POS machine body 1. The top cover 2 and the end screw protrusion 11 are fixedly connected by fastening screws, which facilitates the fixed connection operation, makes it convenient to use, and facilitates maintenance operations.

[0027] In this embodiment, the inclined slot 13 is inclined at 30 to 45 degrees toward the side away from the inner exposed chamber 10. The inclined angle of the snap-fit ​​protrusion 21 is the same as the inclined angle of the inclined slot 13. The size of the snap-fit ​​protrusion 21 is adapted to the size of the inclined slot 13, which facilitates the limiting and fixing operation of the end of the front cover plate 20.

[0028] Specifically, multiple bottom support protrusions 22 arranged in a matrix are fixedly installed on the outer surface of the top cover 2. The cross-section of the bottom support protrusions 22 is hemispherical, so that the bottom support protrusions 22 can be used to support the table.

[0029] Furthermore, multiple downward pressing protrusions 23 arranged in a matrix are fixedly installed on the inner surface of the top cover 2. A downward pressing rubber pad 231 is fixedly installed at the bottom end of the downward pressing protrusions 23. The downward pressing rubber pad 231 presses against the surface of the electronic device inside the inner exposed cavity 10 to achieve the pressing operation.

[0030] In addition, a central heat dissipation plate 24 is integrally formed at the center of the top cover 2. The thickness of the central heat dissipation plate 24 is equal to the thickness of the top cover 2, which facilitates heat dissipation operation using the central heat dissipation plate 24.

[0031] It is worth noting that the central heat sink 24 has multiple heat-conducting protrusions 25 integrally formed in a matrix arrangement. Heat-conducting pillars 251 are fixedly installed at the bottom of the heat-conducting protrusions 25, and heat-conducting sheets 252 are fixedly installed at the bottom of the heat-conducting pillars 251, which facilitates heat conduction and improves heat dissipation.

[0032] It is worth noting that the heat-conducting plate 252 is located on the inner side of the top cover 2, and the heat-conducting protrusion 25 is located on the outer side of the top cover 2, so that the heat-conducting plate 252 and the heat-conducting protrusion 25 can perform heat conduction operations normally. In addition, the height of the heat-conducting protrusion 25 is less than the height of the bottom support protrusion 22, so that after the bottom support protrusion 22 is supported on the table, there is a certain gap between the heat-conducting protrusion 25 and the table, which is conducive to ventilation.

[0033] When using the portable POS machine of this utility model that is easy to maintain, the snap-fit ​​protrusion 21 is snapped into the inclined slot 13, the top cover 2 is attached to the top surface of the POS machine body 1, and then the top cover 2 is fixed on the end screw protrusion 11 with fastening screws to complete the fixing operation. When disassembling, the fastening screws on the top cover 2 are unscrewed, and then the top cover 2 is removed to complete the disassembly operation.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
