[0002] Most bank ATMs and supermarket cash registers are equipped with thermal printers for printing transaction receipts or tickets. A thermal printer usually has a housing, in which a movement is installed. The movement consists of a print head assembly, a support, and a paper cutter. The print head assembly is installed above the support, and the paper cutter is installed on one side of the support and the print head assembly. A paper feed channel is formed between the print head assembly and the support, and the thermal printing paper passes through the paper feed channel.

[0003] Most of the existing printers are provided with a rotating shaft for installing a paper pressing plate or a paper pressing frame, and the rotating shaft is directly installed on the movement support. Specifically, an annular groove is provided at one end of the rotating shaft, and a C-shaped clip is installed in the annular groove so that the rotating shaft is installed on the movement support, which plays a limiting role and prevents the rotating shaft from moving along its central axis. In this way, an annular groove needs to be opened and the clip needs to be installed in place. However, the installation of the clip mostly requires the cooperation of auxiliary fixtures to achieve quick installation, so the assembly process is relatively cumbersome.

[0004] In view of this, the inventor specially designed a movement shaft and a thermal printer that are easy to install, and this case was thus created. Utility Model Content

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] Example 1

[0034] See also Figures 1 to 7, is a movement shaft that is easy to install as embodiment 1 of the utility model, including a movement support 10, a rotating shaft 20, and a gear cover 221 annular inclined surface; 30, the rotating shaft 20 is arranged on the movement support 10; the gear cover 221 annular inclined surface; 30 is arranged on the movement support 10, and abuts against one end of the rotating shaft 20 to limit its movement along the central axis direction, that is, the rotating shaft 20 can be restricted to the movement support 10 by the gear cover 221 annular inclined surface; 30. The movement shaft of the utility model restricts the rotating shaft 20 to the movement support 10 by setting the gear cover 221 annular inclined surface; 30 to prevent the rotating shaft 20 from moving along the direction of its central axis, so the rotating shaft 20 can be restricted to the movement support 10 without using a C-type buckle, thereby realizing a quick and convenient installation of the rotating shaft 20.

[0035] Please refer to Figure 4 The rotating shaft 20 includes a main body 21 and a mounting portion 22 disposed at one end of the main body 21. The outer diameter of the mounting portion 22 is smaller than the outer diameter of the main body 21. The movement support 10 is provided with a mounting hole 11 for cooperating with the mounting portion 22. Through the cooperation of the mounting portion 22 and the mounting hole 11, one end of the rotating shaft 20 can be restricted. When the gear cover 221 annular inclined surface 30 is installed in place, the rotating shaft 20 can be prevented from moving to the other end. Therefore, through the cooperation of the mounting portion 22 and the gear cover 221 annular inclined surface 30, the rotating shaft 20 can be quickly and conveniently installed, and there is no need to use a C-type buckle, which reduces the cost of parts.

[0036] One end of the main body 21 without the mounting portion 22 abuts against the annular inclined surface 30 of the gear cover 221. Specifically, the mounting portion 22 is located at one end of the main body 21 away from the annular inclined surface 30 of the gear cover 221.

[0037] Please refer to Figures 5 to 7 , the gear cover 221 annular inclined surface; 30 is provided with two first buckles 31 arranged side by side below, and at least one second buckle 32 is provided above, the movement support 10 is provided with a first slot 13 matched with the first buckle 31, and is also provided with a second slot 14 matched with the second buckle 32, through the first buckle 31 matched with the first slot 13, the second buckle 32 matched with the second slot 14, so that the gear cover 221 annular inclined surface; 30 is better and faster installed on the side of the movement support 10, and the number of the first buckle 31 and the second buckle 32 is selected and set according to actual needs, and the movement support 10 is also provided with an inclined surface for facilitating the installation of the first buckle 31 and the second buckle 32.

[0038] In order to better restrict and fix the annular inclined surface 30 of the gear cover 221, a third clip 33 is also provided on the side wall of the annular inclined surface 30 of the gear cover 221, and a third clip groove 15 cooperating with the third clip 33 is provided on the movement support 10. The third clip 33 cooperates with the first clip 31 and the second clip 32 to ensure that the annular inclined surface 30 of the gear cover 221 is stably installed on the movement support 10.

[0039] An annular inclined surface is set at one end of the mounting portion 22 away from the main body portion 21, so that the rotating shaft 20 can better pass through the mounting hole 11, and the rotating shaft 20 can be quickly installed; the movement support 10 is also provided with a first through hole 12 for the rotating shaft 20 to pass through. Specifically, the end of the rotating shaft 20 with the mounting portion 22 first passes through the first through hole 12 and is embedded in the mounting hole 11. Finally, the gear cover 221 is installed on the annular inclined surface 30 on the movement support 10.

[0040] Example 2

[0041] See also Figures 1 to 7 , is a thermal printer as embodiment 2 of the utility model, which adopts the structure of the core shaft in embodiment 1 that is easy to install.

[0042] The printer also includes a gear set arranged on the movement support 10, and the movement support 10 is provided with a first support column 16 and a first positioning step 17 of the second support column 161 for installing the gear set; a first positioning step is arranged at the end of the first support column 16, and a second positioning step 171 is arranged on the first positioning step 17 of the second support column 161; a second through hole 34 and a third through hole 35 for embedding the first positioning step and the second positioning step 171 are arranged on the gear cover 221 annular inclined surface 30, and when the gear cover 221 annular inclined surface 30 is installed, the second through hole 34 on the gear cover 221 annular inclined surface 30 cooperates with the first positioning step, and the third through hole 35 cooperates with the second positioning step 171, and at the same time, the gears of the gear set are better restricted to the first support column 16 and the first positioning step 17 of the second support column 161; therefore, the rotation shaft 20, the gear and the like can be limited by a gear cover 221 annular inclined surface 30, thereby improving the convenience of assembly and the cost of installation.

[0043] In summary, the movement shaft of the utility model limits the rotating shaft to the movement support by setting a gear cover to prevent the rotating shaft from moving along the direction of its central axis. Therefore, the rotating shaft can be limited to the movement support without using a C-shaped buckle, thereby achieving quick and convenient installation of the rotating shaft.

[0044] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
