[0026] In order to better understand the purpose, structure and function of the utility model, the specific embodiment of the utility model "a surface cover reinforcement structure" is further described in detail below in conjunction with the accompanying drawings.

[0027] See also Figure 1-Figure 3 In this embodiment, the cover reinforcement structure is a component provided on the printer, especially on a portable printer; the reinforcement structure comprises a cover 100, a bottom cover 200 and a cutter assembly 400, the cover 100 is covered on the bottom cover 200 to form a printer chamber, a guide groove 101 is provided on the cover 100, the cutter assembly 400 is provided on the cover 100, and can slide along the guide groove 101 to complete the paper cutting action; a first rib 102 and a second rib 103 are fixedly connected to the inner wall of the cover 100, and the first rib 102 and The second ribs 103 are all parallel to the guide groove 101, and a support groove 104 is formed between the first ribs 102 and the second ribs 103. Abutment pieces 105 are fixedly connected at both ends of the support groove 104. A metal strip 300 is arranged in the support groove 104. The metal strip 300 is preferably made of stainless steel. Both ends of the metal strip 300 are respectively abutted against the abutment piece 105, and the metal strip 300 is fitted with the inner wall of the face cover 100. In this way, the face cover 100 can be supported to prevent deformation of the face cover 100 without occupying the space of the printer chamber. Preferably, the lengths of the first rib 102 and the second rib 103 are both greater than or equal to the length of the guide groove 101, so that the length of the support groove 104 is also greater than or equal to the guide groove 101. When the metal strip 300 is arranged in the support groove 104 and abuts against the abutment pieces 105 at both ends of the support groove 104, it can provide an optimal support effect to prevent the surface cover 100 from being deformed when the cutter assembly 400 moves to cut paper.

[0028] See also Figure 5 In this embodiment, in order to further increase the strength of the reinforcement structure, a reinforcement arm 301 is fixed to one side of the metal strip 300, and the reinforcement arm 301 and the metal strip 300 form a certain angle, preferably 90 degrees; the reinforcement arm 301 abuts and fits the first rib 102, and the other side of the metal strip 300 abuts and fits the second rib 103; preferably, the metal strip 300 and the reinforcement arm 301 are integrally formed, and the reinforcement arm 301 is formed by bending and extending one side of the metal strip 300. Adding the reinforcement arm 301 and abutting and fitting the first rib 102 can further increase the strength of the reinforcement structure, while not occupying too much space in the printer chamber.

[0029] See also Figure 3 and Figure 5In this embodiment, in order to ensure that the metal strip 300 fits closely with the inner arm of the face cover 100, a plurality of snap-in slots 106 are provided at the bottom end of the first rib 102, and a plurality of protruding buckles 302 are provided at the edge of the metal strip 300. The metal strip 300 and the first rib 102 are snap-connected through the snap-in slots 106 and the protruding buckles 302 to limit the position of the metal strip 300.

[0030] More specifically, in the present embodiment, notches 303 are provided at both ends of the metal strip 300, which can guide the two ends of the metal strip 300 to better abut against the abutment 105. At the same time, the setting of the notches 303 can prevent the two ends of the metal strip 300 from being offset from the abutment 105, so that the centers of the metal strip 300 and the abutment 105 are always in a straight line, thereby achieving the best supporting effect and preventing the surface cover 100 from deformation.

[0031] See also Figure 3 and Figure 4 In the present embodiment, an extrusion piece 201 is provided on the bottom cover 200. When the front cover 100 is covered on the bottom cover 200, the extrusion piece 201 abuts against the metal strip 300, so that the metal strip 300 is more closely fitted to the inner wall of the front cover 100; as a preferred solution, the abutment piece 105 is preferably a cylindrical piece, and the extrusion piece 201 is preferably a sleeve piece; the extrusion piece 201 corresponds to the abutment piece 105 one by one, and the extrusion piece 201 is sleeved on the abutment piece 105 and abuts against the metal strip 300; in this way, the covering of the front cover 100 and the bottom cover 200 can be limited, and the extrusion piece 201 can further limit the metal strip 300, while saving the space of the printer chamber.
