[0019] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figure 1 - Figure 4As shown, the utility model provides a technical solution: a charging roller for a printer that is easy to install, comprising a bottom plate 1, a shell 2 is fixedly connected to the top of the bottom plate 1, through grooves 3 are provided around the shell 2, an adjustment box 4 is slidably connected to the inside of the shell 2, there are two adjustment boxes 4 and both are slidably connected to the inside of the shell 2, a mounting plate 5 is fixedly connected to the top of the adjustment box 4, a charging roller body 6 is arranged inside the mounting plate 5, adjustment grooves 7 are provided at both ends of the adjustment box 4, an adjustment plate 8 is slidably connected to the inside of the adjustment groove 7, a chuck groove 9 is provided at the bottom of the adjustment plate 8, an insert block 10 is fixedly connected to the bottom of the adjustment plate 8, and the bottom plate 1 is provided with a slot 9. A straight groove 11 is provided at the bottom, and slots 12 used in conjunction with the plug block 10 are provided at both ends of the straight groove 11. The staff pushes the adjustment plate 8 into the adjustment groove 7, so that the adjustment plate 8 drives the plug block 10 to release the limit between the slot 12, and the staff moves the adjustment box 4 to the outside, so that the adjustment box 4 drives the mounting plate 5 to release the limit between the charging roller body 6. When the staff needs to install the charging roller body 6, the charging roller body 6 is aligned with the hole inside the bearing 18, and the adjustment box 4 is moved to clamp the charging roller body 6. Through the above settings, the staff can install and disassemble the charging roller body 6.

[0021] Reference Figure 4 As shown, in this implementation scheme: the side of the adjustment plate 8 close to the inside of the adjustment slot 7 is fixedly connected with a force storage spring 13, and the side of the force storage spring 13 away from the adjustment plate 8 is fixedly connected to the inside of the adjustment slot 7. When the staff pushes the adjustment plate 8 toward the inside of the adjustment slot 7, the adjustment plate 8 squeezes the force storage spring 13 to compress and store force, and at the same time drives the plug block 10 to release the limit between the plug block 10 and the slot 12. The staff aligns the plug block 10 with the slot 12 and releases the adjustment plate 8. Under the action of the rebound force of the force storage spring 13, the adjustment plate 8 quickly drives the plug block 10 to be inserted into the slot 12 for fixation.

[0022] Reference Figure 4 As shown, in this embodiment: slide grooves 14 are opened on both sides of the adjustment groove 7, and sliders 15 are fixedly connected on both sides of the adjustment plate 8. The surface of the slider 15 is slidably connected to the inside of the slide groove 14. When the staff moves the adjustment plate 8, the adjustment plate 8 drives the slider 15 to slide inside the slide groove 14. Through the above-mentioned arrangement, the moving trajectory of the adjustment plate 8 is fixed, thereby avoiding the adjustment plate 8 from getting stuck when moving.

[0023] Reference Figure 4 As shown, in this embodiment: the size of the plug block 10 is matched with the size of the slot 12, and the surface of the plug block 10 is slidably connected to the inside of the slot 12. By matching the size of the plug block 10 with the size of the slot 12, a tight fit between the two is ensured. This design not only improves the stability of the overall structure, but also enhances its durability during use.

[0024] Refer to Figure 4 As shown, in this embodiment: guide grooves 16 are provided on both sides inside the through groove 3, guide blocks 17 are fixedly connected to both sides of the adjustment box 4, and the surface of the guide block 17 is slidably connected to the inside of the guide groove 16. When the staff slides the adjustment box 4, the adjustment box 4 drives the guide block 17 to slide inside the guide groove 16. Through the above settings, these guide blocks 17 are closely fitted with the inner wall of the guide groove 16 to ensure that the adjustment box 4 will not shift or shake during the sliding process.

[0025] Refer to Figure 1 As shown, in this embodiment: a bearing 18 is installed inside the mounting plate 5, and the surface of the charging roller body 6 is rotatably connected to the inside of the bearing 18. Through the setting of the bearing 18, when the charging roller body 6 is inserted into the bearing 18, the charging roller body 6 rotates more smoothly. This design not only reduces friction but also improves the overall stability and durability.

[0026] Refer to Figure 1 As shown, in this embodiment: the material of the mounting plate 5 is high-strength alloy. Through the setting that the material of the mounting plate 5 is high-strength alloy, the stability and durability of the mechanical structure are ensured. This alloy not only has excellent tensile strength but also has good corrosion resistance, enabling it to maintain long-term reliability in harsh working environments.

[0027] Working principle: The staff pushes the adjusting plate 8 into the adjusting groove 7, so that the adjusting plate 8 drives the insertion block 10 to release the limit with the slot 12. The staff moves the adjusting box 4 outward, so that the adjusting box 4 drives the mounting plate 5 to release the limit with the charging roller body 6. When the staff needs to install the charging roller body 6, align the charging roller body 6 with the hole inside the bearing 18 and move the adjusting box 4 to clamp the charging roller body 6. Through the above settings, it is convenient for the staff to install and disassemble the charging roller body 6. When the staff pushes the adjusting plate 8 into the adjusting groove 7, the adjusting plate 8 squeezes the energy storage spring 13 to compress and store energy, and at the same time drives the insertion block 10 to release the limit with the slot 12. The staff aligns the insertion block 10 with the slot 12 and releases the adjusting plate 8. Under the action of the resilience of the energy storage spring 13, the adjusting plate 8 quickly drives the insertion block 10 to insert into the slot 12 for fixation. When the staff moves the adjusting plate 8, the adjusting plate 8 drives the slider 15 to slide inside the sliding groove 14. Through the above settings, the movement track of the adjusting plate 8 is fixed, avoiding jamming when the adjusting plate 8 moves. By making the size of the insertion block 10 match the size of the slot 12, the tight fit between the two is ensured. This design not only improves the stability of the overall structure but also enhances its durability during use. When the staff slides the adjusting box 4, the adjusting box 4 drives the guiding block 17 to slide inside the guiding groove 16. Through the above settings, these guiding blocks 17 fit tightly with the inner wall of the guiding groove 16, ensuring that the adjusting box 4 will not shift or shake during sliding. Through the setting of the bearing 18, when the charging roller body 6 is inserted into the bearing 18, the charging roller body 6 rotates more smoothly. This design not only reduces friction but also improves the overall stability and durability. Through the setting that the material of the mounting plate 5 is high-strength alloy, the stability and durability of the mechanical structure are ensured. This alloy not only has excellent tensile strength but also has good corrosion resistance, enabling it to maintain long-term reliability in harsh working environments.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
