Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a latch structure of a portable thermal printer. Background Art

[0002] The working principle of a thermal printer is to install a semiconductor heating element on the print head. After the print head is heated and contacts the thermal printing paper, the required pattern can be printed out. The image is generated by heating and producing a chemical reaction in the film, so that a large amount of heat energy is generated inside the printer during imaging work, so that the printer body will become hot after working for a long time. Therefore, the following disadvantages exist in the use of existing printers: 1. When general printers are dissipating heat, they usually only dissipate heat through heat dissipation holes on the casing, which makes the heat dissipation effect poor; 2. The base and casing of general printers are mostly fixed with screws, which increases the inconvenience of personnel disassembling the body for inspection when a malfunction occurs.

[0025] In this embodiment, the base heat dissipation mechanism 8 includes a bottom shell 81, and the four corners of the upper end of the bottom shell 81 are fixedly connected with latch buckle components 83, a heat dissipation fan 82 is fixedly connected to the middle of the lower wall of the bottom shell 81, and anti-skid pads 84 are fixedly connected to the lower end of the bottom shell 81. The heat dissipation fan 82 is communicated with the interior of the printer housing 1, and the upper end surface of the heat dissipation fan 82 is flush with the lower end surface of the printer housing 1; by setting the base heat dissipation mechanism 8, the heat dissipation fan 82 is fixedly installed on the lower wall of the bottom shell 81, and the heat dissipation fan 82 is flush with the lower end surface of the printer housing 1 and the heat dissipation fan 82 is communicated with the inside of the printer housing 1 but not in contact, so that when the heat dissipation fan 82 is working, the heat dissipation fan 82 can blow air to quickly exchange the hot air in the printer housing 1 with the external airflow through a plurality of heat dissipation holes 2, thereby quickly cooling and dissipating the heat to provide good protection for the internal parts of the printer.

[0026] In this embodiment, the latch buckle component 83 includes a card block 831, which is fixedly connected to the upper end of the bottom shell 81, and a U-shaped groove 832 is opened on the upper end of the card block 831. A rotating column 833 is inserted and movably connected to the side of the card block 831 away from the printer housing 1, and a fixing component 834 is fixedly connected to the outer surface of the rotating column 833. The four card blocks 831 are tightly against the printer housing 1 but not fixed. The two latch buckle components 83 distributed longitudinally in pairs are symmetrically distributed. The fixing component 834 includes a connecting block 8341. The front end of the connecting block 8341 is opened with a through hole 8342 that passes through the front and back. The upper end of the connecting block 8341 is fixedly connected with a special-shaped latch block 8343. The connecting block 8341 is fixedly connected to the rotating column 833 through the through hole 8342. The connecting block 8341 and the special-shaped latch block 8343 are both located in the U-shaped groove 832.
