AI Technical Summary
The exposed drive gear design of existing thermal printers results in inconsistent appearance and makes disassembly and assembly difficult, increasing costs and operational complexity.
The design features a detachable end cap, which slides and slides to allow for a sliding fit between the end cap and the housing, covering the drive gear and simplifying the assembly and disassembly process. The end cap also serves as a mounting base for the circuit board.
It achieves overall appearance consistency, reduces manufacturing costs, simplifies operation steps, and improves the convenience of assembly and disassembly.

TECHNICAL FIELD
[0001] The present application relates to a printing device, in particular to a thermal printer. BACKGROUND
[0002] The existing thermal printer basically comprises a casing and a thermal printer core arranged in the casing, the casing has a paper outlet, the thermal printer core has a cutter capable of cutting paper and a driving gear capable of promoting the cutter to return to the original position after being pushed, and the driving gear is partially exposed on the upper end surface of the thermal printer core. After the cutter is stuck, the driving gear needs to be manually pushed to restore the cutter. The existing technology separately increases a small opening on the casing and increases a cover plate to shield the opening. Before manually pushing the driving gear, the cover plate needs to be separately opened. The overall design of the cover plate is not beautiful, and the cost and operation difficulty are increased, which needs to be improved. SUMMARY
[0003] The technical problem to be solved by the present application is to provide a thermal printer with a consistent overall appearance and convenient disassembly and assembly.
[0004] The technical scheme adopted by the present application to solve the above technical problem is: a thermal printer, comprising a casing and a thermal printer core arranged in the casing, the casing has a paper outlet, the thermal printer core has a cutter capable of cutting paper and a driving gear capable of promoting the cutter to return to the original position after being pushed, the cutter is arranged close to the paper outlet, and the driving gear is partially exposed on the upper end surface of the thermal printer core, characterized in that the casing comprises a shell and an end cover, the shell has a mounting port on one side of the upper end, the thermal printer core is arranged in the inner cavity of the shell, the driving gear is partially exposed on the mounting port, and the end cover is detachably arranged on the mounting port and covers the driving gear.
[0005] The end cover is slidably arranged on the mounting port, which facilitates the disassembly and assembly of the end cover.
[0006] Further, the mounting port has sliding grooves on both sides of the upper end, and correspondingly, the end cover has sliding blocks on both sides of the lower end which are slidably matched with the sliding grooves.
[0007] Further, the sliding grooves have clamping portions at the ends, and correspondingly, the sliding blocks are formed with clamping grooves matched with the clamping portions. After assembly, the connection is firm and not easy to be disconnected.
[0008] Further, the mounting port has an insertion hole on one side between the sliding grooves, the end cover has an insertion block, and when the end cover is mounted on the mounting port, the insertion block is matched in the insertion hole.
[0009] The outer end surface of the end cover has an operation button, and the inner side surface has a circuit board matched with the operation button to control the thermal printer core. Thus, the end cover can also serve as a mounting base of the circuit board, facilitating the arrangement of other components in the shell.
[0010] Further, the paper outlet is formed at the joint of the shell and the end cover.
[0011] Compared with the prior art, the mounting port of the end cover and the shell is detachably assembled, the end cover can cover the upper end surface of one side of the shell, thus the overall appearance is consistent after assembly, the cover member is reduced, and the manufacturing cost is lowered; the sliding matching is realized by combining the plug-in structure, thus facilitating the assembly and disassembly.

[0016] The present application will be further described in detail below in combination with the embodiment and the accompanying drawings.
[0017] As Figures 1-4 shown, the thermal printer in the embodiment includes a shell 1 and a thermal printer core 2 arranged in the shell 1, the shell 1 has a paper outlet 1a, the thermal printer core 2 has a cutter capable of cutting paper and a driving gear 21 capable of driving the cutter to return to the original position after being actuated, the cutter is arranged close to the paper outlet 1a, the driving gear 21 is partially exposed on the upper end surface of the thermal printer core 2, the shell 1 includes a shell body 11 and an end cover 12, the shell body 11 has a mounting port 1b on one side of the upper end, the thermal printer core 2 is arranged in the inner cavity of the shell body 11, the driving gear 21 is partially exposed on the mounting port 1b, and the end cover 12 is detachably arranged on the mounting port 1b and covers the driving gear 21. The paper outlet 1a in the embodiment is formed at the joint of the shell body 11 and the end cover 12.
[0018] The outer end surface of the end cover 12 has an operation button 31, and the inner side surface has a circuit board 3 matched with the operation button 31 to control the thermal printer core 2.
[0019] Specifically, the end cover 12 is slidably arranged on the mounting port 1b. The upper end of the mounting port 1b has sliding grooves 111 on both sides, and the lower end of the end cover 12 has sliding blocks 14 which are slidably arranged in the sliding grooves 111. The end of the sliding groove 111 has a clamping portion 112, and the sliding block 14 is formed with a clamping groove 141 which is adapted to the clamping portion 112. The mounting port 1b has an insertion hole 15 on one side between the sliding grooves 111, and the end cover 12 has an insertion block 13 which is adapted to the insertion hole 15 when the end cover 12 is mounted on the mounting port 1b.
[0020] After the cutter is clamped, the end cover is manually driven to move transversely, so that the sliding blocks are extracted from the sliding grooves, and the end cover is separated from the mounting port. After the driving gear is driven, the cutter is returned to the original position, the end cover is slid along the sliding grooves to the original position, the insertion block is adapted to the insertion block, and the clamping portion is clamped in the clamping groove.
[0021] The end cover and the mounting port of the shell are detachably assembled, the end cover covers the upper end surface of one side of the shell, the overall appearance is consistent after assembly, and the sliding cooperation is realized by combining the detachable structure, so that the assembly and disassembly are facilitated.
