FIG. 1 and FIG. 2 illustrate an embodiment of a POS device. The POS device comprises a housing 10, two displays 20, a circuit board 30, and a storage device 40.
The housing 10 comprises a main body 11, a cover 12, and a plurality of hinges 13.
The main body 11 comprises a base board 111, a first side board 112, a second side board 114, an outer board 115, a top board 116, and a support board 117. The first side board 112 and the second side board 114 are connected to two opposite sides of the base board 111. The outer board 115 is attached to the base board 111, the first side board 112, and the second side board 114. The top board 116 is attached to the first side board 112, the second side board 114, and the outer board 115. The support board 117 is attached to the base board 111, the top board 116, the first side board 112, and the second side board 114, and is opposite to the outer board 115. A side of the support board 117 back to the outer board 115, the base board 111, the top board 116, the first side board 112, and the second board 114 cooperatively define a receiving space 110. An opening 118 is defined on a middle portion of the support board 117. Two pairs of fixing pillars 1171 respectively protrude from a top and a bottom of the support board 117, near the first side board 112. Each fixing pillar 1171 defines a connecting hole 1173 perpendicular to the support board 117. A lock 14 is installed on a middle portion of the second side board 114 away from the outer board 115. A latch 141 is mounted to an inner side of the second side board 114 and connected to the lock 14. The latch 141 can be controlled by the lock 14 to rotate out of the receiving space 110. A tab 1161 protrudes from the top board 116 away from the outer board 115. One of the displays 20 is rotatably installed on the outer board 115, near the top board 116. The base board 111, the first side board 112, the second board 114, the outer board 115, the top board 116, and the support board 117 cooperatively define a mounting space, for installing a keyboard, a cashbox, and other apparatus.
The cover 12 comprises a base plate 120, a first side plate 121, a second side plate 123, a top plate 126, and a mounting bracket 124. The first side plate 121 and the second side plate 123 perpendicularly extend inward from two opposite sides of the base plate 120. The top plate 126 protrudes inward from a top edge of the base plate 120 and is attached to the first side plate 121 and the second side plate 123. A notch 1261 is defined in a middle portion of the top plate 126. The other display 20 is rotatably installed on the outside of the top of the cover 12 by a connecting bracket 21 extending through the notch 1261 and fixed to the base plate 120. Two pairs of fixing pillars 1212 respectively protrude from a top and a bottom of the base plate 120, near the first side plate 121. Each fixing pillar 1212 defines a connecting hole 1215 perpendicular to the base plate 120. Two connecting portions 122 protrude from inner sides of the first side plate 121 and the second side plate 123.
The mounting bracket 124 comprises a mounting plate 1242 parallel to base plate 120, two extending plates 1245 extending from two opposite side edges of the mounting plate 1242 toward the base plate 120, and two fixing plates 1247 respectively extending outward from edges of the extending plates 1245 away from the mounting plate 1242. The fixing plates 1247 are fixed on the connecting portions 122, respectively. The base plate 120, the connecting portions 122, and the mounting bracket 124 cooperatively define a housing space 127. The circuit board 30 is received in the housing space 127, with connectors of the circuit board 30 facing up. A locking hole 1241 is defined in a middle of the fixing plate 1247 near the second side plate 123. A storage device mounting bracket 1248 is installed on a middle portion of the outer surface of the mounting plate 1242. The storage device mounting bracket 1248 is U-shaped and defines a top opening receiving groove 1250 (shown in FIG. 5) for receiving the storage device 40. Two fixing portions 1251 are respectively formed on tops of two opposite sides of the storage device mounting bracket 1248. The storage device 40 can slide into the receiving groove 1250 and a resilient handle 41 coupled to an end of the storage device 40 can be latched to the fixing portions 1251.
Each hinge 13 comprises two fixing blocks 131. Each fixing block 131 is rotatably connected to a plurality of connecting sheets 132. The connecting sheets 132 of one fixing block 131 overlap with the connecting sheets 132 of the other fixing block 131; and the connecting sheets 132 of the two fixing blocks 131 are rotatably connected to a shaft 135 extending through the connecting sheets 132. Two fixing sheets 133 respectively extend from a top and a bottom of each fixing block 131, near the corresponding connecting sheets 132. Each fixing sheet 133 defines a through hole 134.
FIG. 3 illustrates an assembled, isometric view of the POS device of FIG. 1. In assembly, one of the fixing blocks 131 of each hinge 13 can be placed into the receiving space 110, adjacent to the first side board 112, and between one pair of fixing pillars 1171. The through holes 134 of the fixing sheets 133 directly face the corresponding connecting holes 1173 of the fixing pillars 1171. A plurality of fasteners can extend through the through holes 134 to engage in the connecting holes 1173, fastening the hinges 13 to the main body 11. Another fixing block 131 of hinges 13 can be placed into the cover 12, adjacent to the first side plate 121, and between the corresponding pair of fixing pillars 1212. The through holes 134 of the fixing sheets 133 directly face the corresponding connecting holes 1215 of the fixing pillars 1212. A plurality of fasteners can extend through the through holes 134 to engage in the connecting holes 1215, fastening the hinges 13 to the cover 12. Then, the cover 12 is rotatably installed to the main body 11.
FIG. 4 illustrates an isometric view of the POS device at a working state. Before working, the cover 12 can be rotated to cover the main body 11. The first side plate 121 can be rotated to attach the first side board 112, the second side plate 123 can be rotated to attach the second side board 124, and the tab 1161 of the top board 116 can cover the notch 1261 of the top plate 126. The lock 14 can be operated to control the latch 141 to extend through then lock with the locking hole 1241 of the cover 12. Then, the cover 12 is fastened to the main body 11; the storage device bracket 1248 extends through the opening 118 to be received between the outer board 115 and the support board 117.
FIG. 5 illustrates an isometric view of the POS device in maintenance. During maintenance, the lock 14 can be operated to control the latch 141 to release the locking hole 1241. The cover 12 can be rotated away from the main body 11. The handle 41 can be operated to remove the storage device 40 from the receiving groove 1250. The mounting bracket 124 can be taken down, for further maintenance of the circuit board 30.
In another embodiment, each fixing block 131 and the corresponding connecting sheets 132 can be an organic whole.
