Description

Technical Field

[0001] The utility model relates to the field of POS machines, and more specifically, to a POS machine housing which is easy to disassemble and assemble. Background Art

[0002] Current POS machines usually put a roll of printing paper inside the machine to print receipts. When the printing paper runs out, the cover needs to be opened to change the paper. In order to facilitate users to open the cover to change paper, the existing POS machine cover is mostly connected to the POS machine housing with a shaft. Most of the existing flip cover shafts are integrally formed on both sides of the flip cover. When installing, the shaft needs to be pressed into the shaft hole with great force. This assembly structure has the following inconveniences: 1. After a long time, the shaft is easy to fall out of the shaft hole, causing the flip cover to easily fall off the housing. 2. When disassembling the flip cover, the shaft needs to be pulled out of the shaft hole by force, which is easy to cause the shaft to break and is not convenient for disassembly. Utility Model Content

[0022] The rear shell is provided with a receiving groove 25 for accommodating the first shaft seat 13 and the second shaft seat 14, the first side wall of the receiving groove 25 is provided with a first adapter hole 26 for inserting the first end of the first rotating shaft 21 for rotational connection, and the second side wall of the receiving groove 25 is provided with a second adapter hole for inserting the second end of the second rotating shaft 22 for rotational connection.

[0023] In order to improve the reliability of the first rotating shaft 21 and the second rotating shaft 22, the first rotating shaft 21 and the second rotating shaft 22 are both metal rotating shafts, preferably stainless steel rotating shafts.

[0024] It can be understood that the length of the first rotating shaft 21 is greater than the length of the first axial hole 19, and the length of the second rotating shaft 22 is greater than the length of the second axial hole 20. The first plug hole 23 and the second plug hole 24 are both blind holes.

[0025] Preferably, the length of the first rotating shaft 21 is greater than the sum of the depths of the first shaft hole 19 and the first plugging hole 23. The length of the second rotating shaft 22 is greater than the sum of the depths of the second shaft hole 20 and the second plugging hole 24.

[0026] When using the POS machine housing that is easy to disassemble and assemble of the utility model, the first rotating shaft 21 and the second rotating shaft 22 can be respectively inserted into the first shaft hole 19 and the second shaft hole 20, and the first shaft seat 13 and the second shaft seat 14 can be placed in the receiving groove 25, and then the first end of the first rotating shaft 21 can be inserted into the first transfer hole 26, and the second end of the second rotating shaft 22 can be inserted into the second transfer hole. After the card block 15 is inserted into the card slot 16, the barb 17 and the buckle hole 18 are buckled. The first rotating shaft 21 is moved in the first shaft hole 19 toward the first plug hole 23 and inserted into the first plug hole 23, and the second rotating shaft 22 is moved in the second shaft hole 20 toward the second plug hole 24 and inserted into the second plug hole 24, so that the flip cover 12 and the rear shell 11 can be rotatably connected.

[0027] In the present application, the first rotating shaft 21 and the second rotating shaft 22 are separated from the flip cover 12, which not only reduces the difficulty and cost of mold opening, but also allows the first rotating shaft 21 and the second rotating shaft 22 to be changed into a metal axis, which is more durable and reliable. Secondly, the disassembly structure of the present application is adopted, and assembly and maintenance are more convenient. The block 15 can prevent the first rotating shaft 21 and the second rotating shaft 22 from retreating, play a role in preventing them from falling off, and also facilitate maintenance and disassembly.

[0030] In the present application, in order to facilitate the insertion of the first rotating shaft 21 into the first transfer hole 26, the hole diameter of the first transfer hole 26 is larger than the diameter of the first rotating shaft 21. After the first rotating shaft 21 is inserted into the first transfer hole 26, the first "C"-shaped seat 29 at the first end of the first push rod 27 is pushed against the first rotating shaft 21, and then the first push rod 27 is fixed by the first connecting seat 31, which can prevent the first rotating shaft 21 from loosening and will not interfere with the rotation of the first rotating shaft 21.

[0031] Similarly, a second push rod 28 is provided on the second side of the bottom of the rear shell 11, which can be inserted into the second adapter hole and abut the second end of the second rotating shaft 22. The first end of the second push rod 28 is provided with a second "C"-shaped seat 30 abutting against the second rotating shaft 22, and the second end of the second push rod 28 is provided with a second connecting seat 32 fixedly connected to the rear shell 11.

[0032] Specifically, the second connecting seat 32 is provided with at least one second connecting hole.

[0033] Similarly, to facilitate the insertion of the second rotating shaft 22 into the second adapter hole, the diameter of the second adapter hole is larger than the diameter of the second rotating shaft 22. After the second rotating shaft 22 is inserted into the second adapter hole, the second "C"-shaped seat 30 at the first end of the second push rod 28 is pushed against the second rotating shaft 22, and then the second push rod 28 is fixed by the second connecting seat 32, which can prevent the second rotating shaft 22 from loosening and will not interfere with the rotation of the second rotating shaft 22.
