DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] In order to facilitate the addition of a quick disassembly mechanism and improve the convenience of movement disassembly and assembly, thereby improving the use effect, such as Figure 1-3 As shown, the thermal printer movement that is easy to disassemble described in the utility model includes a bottom plate component 1, a limit component 3 and a heat dissipation component 4. The top of the bottom plate component 1 is provided with a core component 2, the top of the bottom plate component 1 is located on both sides of the core component 2 and the limit component 3 is provided, and the top of the bottom plate component 1 is located on the back of the core component 2 and the heat dissipation component 4 is provided;

[0030] The base plate assembly 1 includes a base plate 101, and the limit assembly 3 includes a limit seat 301, and the limit seat 301 is connected to the base plate 101 by bolts, both sides of the limit seat 301 are connected to the positioning sleeve 302 by bolts, one side of the positioning sleeve 302 is sleeved and connected to the plug rod 303, and one end of the plug rod 303 passes through the limit seat 301 through a reserved hole, and a spring 304 is arranged on the inner side of the plug rod 303 in the positioning sleeve 302.

[0031] When in use, a quick disassembly mechanism can be formed through the base plate 101, the limit seat 301, the positioning sleeve 302, the insertion rod 303 and the spring 304. The sleeve sliding and the plug-in limit method are used to replace the traditional screw fastener installation method, which greatly improves the convenience of disassembly and is more flexible and convenient to use.

[0032] In order to improve the stability of the movement, for example, Figure 2 , Figure 4 As shown, the utility model also includes that the heat dissipation component 4 includes a heat conductive sheet 401 , both sides of the heat conductive sheet 401 are connected to side sheets 402 by welding, and a semiconductor cooling sheet 403 is arranged on the outer side of the heat conductive sheet 401 .

[0033] When in use, an auxiliary heat dissipation and cooling mechanism can be formed through the heat conductive sheet 401, the side sheet 402 and the semiconductor refrigeration sheet 403. The heat generated by the continuous operation of the movement assembly 2 can be dissipated by utilizing the contact with the movement assembly 2, thereby improving the stability of continuous long-term operation and also helping to extend the service life.

[0034] For example, Figure 3 As shown, the utility model also includes that the other side of the positioning sleeve 302 is sleeved with a connecting rod 305, and one end of the pull rod 305 passes through the spring 304 and is connected to the plug rod 303 by bolts, the pull rod 305 includes a threaded section 306, and the end of the positioning sleeve 302 away from the plug rod 303 is connected to the threaded seat 307 by welding, and the pull rod 305 is threadedly connected to the threaded seat 307 through the threaded section 306.

[0035] When in use, the pull rod 305 , the threaded section 306 and the threaded seat 307 are used to facilitate the use of threaded connection to improve the stability of the limiting assembly 3 .

[0036] For example, Figure 5 As shown, the utility model also includes that the core assembly 2 includes a base 201, a thermal sheet 202, an elastic member 203 and a driving motor 205, and rubber roller grooves 204 are provided on both sides of the base 201.

[0037] When in use, the base 201, the thermal sheet 202, the elastic member 203, the driving motor 205 and the rubber roller groove 204 are used to form a thermal printer mechanism.

[0038] For example, Figure 5 As shown, the utility model also includes that both sides of the base 201 are connected to the protrusions 206 by bolts, the surface of the protrusion 206 is provided with a groove 207 corresponding to the insertion rod 303, and the bottom of the base 201 is connected to the insertion block 208 by bolts.

[0039] When in use, the protrusion 206 and the groove 207 facilitate the coordination with the limiting seat 301 and the inserting rod 303 for inserting, limiting, fixing and installing.

[0041] When in use, the plug hole 102 facilitates the insertion of the plug block 208 to perform preliminary limiting processing on the base 201, and the mounting seat 103 facilitates the pre-installation of the bottom plate 101 inside the thermal printer housing by fasteners such as screws.

[0042] When the utility model is in use, the operator first screws the bottom plate 101 into the thermal printer housing through the mounting seat 103 in advance. When installing the core assembly 2, it is only necessary to push the base 201 into the limit seats 301 so that the plug block 208 is inserted into the corresponding jack 102 of the bottom plate 101. At the same time, the spring 304 is used to push the plug rod 303 to slide through the limit seat 301, and one end is stuck in the corresponding groove 207 to complete the plug-in limit. Then the pull rod 305 is rotated, and the pull rod 305 is fixed by the threaded section 306 threadedly connected to the threaded seat 307, thereby completing the rapid installation operation of the core assembly 2. When the core assembly 2 needs to be disassembled, it is only necessary to rotate the pull rod 305 in the opposite direction, and then pull the pull rod 305 outward to pull the base 201 of the core assembly 2 out from between the limit seats 301 to complete the disassembly operation. The structure is simple and easy to operate, and the disassembly and assembly operation is more convenient and flexible, which greatly improves the convenience of subsequent maintenance, disassembly and replacement operations.

[0043] Moreover, during the actual operation of the movement, heat exchange can be performed on the drive motor 205 through the contact between the heat conductive plate 401 and the side plate 402, and the semiconductor refrigeration plate 403 can be used to assist in heat dissipation and cooling, thereby improving the stability of the movement assembly 2 for long-term continuous operation, and also helping to extend the service life of the drive motor 205, making it more stable and reliable to use.
