[0023] The utility model will be described in further detail below in combination with the drawings.

[0024] As Figures 1 to 5 shown, the paper box structure comprises a box body 3, a first width adjusting frame 1 and a second width adjusting frame 2, the first width adjusting frame 1 and the second width adjusting frame 2 can be relatively close or relatively far away and are arranged on the box body 3, the surface of the box body 3 is provided with a transversely arranged rack 31, correspondingly, the end of the second width adjusting frame 2 is provided with a clamping tooth 20 that can mesh with the rack 31 and limit, and the second width adjusting frame 2 is further provided with an operating part that extends outward and thereby controls whether the clamping tooth 20 meshes with the teeth on the rack 31.

[0025] By adopting the above structure, the rack 31 and the clamping tooth 20 that mesh and limit can reliably limit the width between the first width adjusting frame 1 and the second width adjusting frame 2, the limiting of the clamping tooth 20 and the teeth can be cancelled or restored through the operating part, and the width adjustment of the first width adjusting frame 1 and the second width adjusting frame 2 is carried out, which is convenient for the user to adjust the width at any time according to the need, not only convenient to operate, but also can avoid the paper skew, thereby improving the paper conveying flatness and the printing quality stability.

[0026] The end of the second width adjusting frame 2 is provided with an extension arm 23 that extends outward, the clamping tooth 20 is arranged at the end of the extension arm 23 and extends to the direction of the rack 31, and the operating part is arranged on the outer surface of the extension arm 23. The position of the clamping tooth 20 in the embodiment extends outward by 4mm relative to the meshing and limiting structure, so as to better cooperate with the operating part and carry out stable and reliable limiting adjustment.

[0027] The second width adjusting frame 2 comprises a first part 21 arranged close to the surface of the box 3 and a second part 22 extending outwardly from the outer surface of the first part 21. Similarly, the first width adjusting frame 1 also has the structure of the first part and the second part. An extension arm 23 is connected to the outer edge of the first part 21 of the second width adjusting frame 2 and extends to the outside of the second part 22. The surface of the extension arm 23 is provided with a tab 24 extending outwardly and arranged spaced apart from the outer side of the second part 22. The tab 24 and the second part 22 opposite thereto jointly constitute an operating part. With the above structure, since the extension arm 23 and the tab 24 are formed integrally with the second width adjusting frame 2 and the clamping teeth 20 at the outer end, the clamping teeth 20 can be lifted relative to the rack 31 to cancel the meshing limit of the two by manually clamping the second part 22 and the tab 24 and making them relatively close. After adjusting the overall width by laterally moving the second width adjusting frame, the meshing limit of the clamping teeth 20 and the rack 31 can be restored by releasing the second part 22 and the tab 24, which is simple and reliable in operation.

[0028] The tab 24 is arranged outwardly and gradually inclined to the direction of the clamping teeth 20 from the surface of the extension arm 23. Preferably, the inclination of the tab 24 is 4°-6°, and more preferably 5°. With the above structure, the right side of the manually controlled lifting amount structure of the second width adjusting frame 2 (i.e. the tab 24) is offset outwardly, which can increase the intermediate adjustment distance and thus increase the lifting amount of the meshing structure, making the adjustment of the width adjusting frame smoother.

[0029] The rack 31 is arranged close to the first length edge of the box 3. The surface of the box 3 is also provided with a limiting strip 32 close to the second length edge thereof, which is used to limit the first width adjusting frame 1 and the second width adjusting frame 2 when they move outwardly to the set position. The limiting strip 32 is two and corresponds to the outer side of the first width adjusting frame 1 and the outer side of the second width adjusting frame 2 respectively. The inner end of the limiting strip 32 cooperates with the outer edge of the corresponding width adjusting frame to limit it. The provision of the limiting strip 32 can prevent the paper from being skewed due to the left and right swinging of the first and second width adjusting frames during paper feeding.

[0030] The back of the box 3 is provided with a transmission assembly connected with the first width adjusting frame 1 and the second width adjusting frame 2 respectively. When the second width adjusting frame 2 is subjected to a lateral pushing force, the first width adjusting frame 1 and the second width adjusting frame 2 move synchronously under the drive of the transmission assembly to realize relative approaching or relative moving away. With the above structure, the width adjustment of the required width can be realized by controlling the position of the single width adjusting frame, which is convenient to operate.

[0031] The bottom of the first width adjusting frame 1 is provided with a first rack 11 located at the back of the box body 3 and extending towards the second width adjusting frame 2, the bottom of the second width adjusting frame 2 is provided with a second rack 25 located at the back of the box body 3 and extending towards the first width adjusting frame 1, and the back of the box body 3 is further provided with a gear 4 engaged with the first rack 11 and the second rack 25 respectively, and the gear 4 is located between the first rack 11 and the second rack 25. The first rack 11, the second rack 25 and the gear 4 jointly form a transmission assembly. With the above structure, the first width adjusting frame 1 and the second width adjusting frame 2 can be moved synchronously, relatively close or relatively far away, and the paper width constrained can always be kept at the central position, thereby improving the flatness of paper conveying.

[0032] The box body 3 is provided with a first sliding groove 34 extending along the length direction and penetrating through the front and back, and the bottom of the first width adjusting frame and the second width adjusting frame 2 is respectively provided with a guide part 01 capable of guiding cooperation with the corresponding first sliding groove 34. In the longitudinal direction of the width adjusting frame, the guide part 01 and the first sliding groove 34 are cooperated, and the first rack 11 / second rack 25 and the corresponding second sliding groove 35 provided on the box body 3 are cooperated, so that the moving stability of the width adjusting frame is further improved.

[0033] The box body 3 and the width adjusting frame are provided with a rack 31 and a tooth 20 capable of engaging and limiting, so as to reliably limit the width between the first width adjusting frame 1 and the second width adjusting frame 2, and an operation part capable of controlling the engaging position of the tooth 20 and the rack 31 is further provided. The operation part can cancel or restore the limiting of the tooth 20 and the rack, and adjust the width of the first width adjusting frame 1 and the second width adjusting frame 2, so that the user can adjust the width at any time according to the needs, which is not only convenient to operate, but also can avoid paper skewing, thereby improving the flatness of paper conveying and the stability of printing quality.
