DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0020] Please refer to Figures 1 to 8 A foldable POS machine base, the core structure of which is composed of a U-shaped horizontal sheet metal part 1, a lever arm sheet metal part 2 and a connecting sheet metal part 3. The first bending ears 4 are symmetrically arranged on both sides of the U-shaped horizontal sheet metal part 1, and the two sides of the lever arm sheet metal part 2 are equipped with bending connecting arms 5 extending outward. Symmetrical second bending ears 6 are arranged on the connecting sheet metal part 3. These bending ears and the bending connecting arms are hinged to each other through a damping hinge 7, thereby realizing the folding function of the base. In order to improve the aesthetics and durability, the entire internal structure is wrapped by a plastic shell 8.

[0021] The design of the plastic shell 8 is also meticulous: the plastic shell 8 includes an upper cover 10, a front cover 11, a rear cover 12, an upper shell 13 and a lower shell 14. The bottom of the U-shaped horizontal sheet metal 1 is firmly connected to the bottom plate sheet metal 9 by bolts, and the upper cover 10 is installed on the top of the bottom plate sheet metal 9 by screws. The front cover 11 and the rear cover 12 are cleverly set on the periphery of the arm sheet metal 2, and the two are fixed by snap-fitting, which is both beautiful and stable. The periphery of the connecting sheet metal 3 is composed of an upper shell 13 and a lower shell 14. The backs of these two parts of the shell are cleverly designed with a semi-cylinder 15 to cleverly hide the damping hinge 7, adding to the overall aesthetics.

[0022] Furthermore, positioning grooves 17 are designed inside the upper shell 13 and the lower shell 14, which are closely matched with the positioning bent portion 16 on the connecting sheet metal 3 to ensure the stability of the structure. Flanged edges 18 are also provided on both sides of the connecting sheet metal 3, which are in close contact with the inner walls of the upper shell 13 and the lower shell 14, further enhancing the firmness of the connection.

[0023] The design of the upper cover 10 is also ingenious. A boss 19 is provided near the first bending ear 4, and the rest of the part is thinner, which not only saves materials but also improves the aesthetics. An arc-shaped cover plate 20 is cleverly arranged below the arm sheet metal 2. It is located between the two bent connecting arms 5, which not only covers the damping hinge 7 but also increases the overall aesthetics. The horizontal connection portion 21 on the arc-shaped cover plate 20 perfectly matches the mounting hole 22 on the boss 19, which is convenient for installation and disassembly. The horizontal connection portion 21 and the U-shaped horizontal sheet metal 1 are connected by bolts.

[0024] In order to better manage the wire harness, a wire harness channel 23 is designed on the horizontal connection part 21 and the bottom plate sheet metal 9. At the same time, a notch 24 for avoiding the wire harness is also set on the bottom plate sheet metal 9 and the upper cover 10. In addition, a detachable baffle 25 is installed on the front cover 11, and a hanging plate 26 is provided on the baffle 25, which can cooperate with the hanging groove 27 on the front cover 11 to form a wire harness limiting groove 28, which is convenient for organizing and limiting the wire harness.

[0025] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
