[0002] A printer is one of the output devices of a computer and is used to print computer processing results on relevant media. Existing printers are usually equipped with a paper box for storing printed paper. In order to accommodate papers of different sizes, the size of these printer paper boxes can be adjusted. The adjusted paper box exceeds the length of the printer, so part of the paper is exposed to the environment and easily accumulates dust.

[0003] After searching, the Chinese patent publication number CN209079481U discloses a dustproof mechanism for a printer paper box, including a paper box, a paper box extension plate is arranged at the front, and a matching part with the paper box dust cover is arranged on the front side of the paper box extension plate; a left bracket, a left paper box dust cover guide groove is arranged on the side; a right bracket, a right paper box dust cover guide groove is arranged on the side; a paper box dust cover, a left guide rail matching with the paper box dust cover guide groove is arranged on the left side, a right guide rail matching with the right paper box dust cover guide groove is arranged on the right side, and a paper box extension cover matching part matching with the paper box dust cover matching part is arranged on the front side.

[0004] This patent provides a paper box dust cover and cooperates with the paper box extension plate, so that the paper box dust cover can move with the paper box extension plate, and the paper box dust cover can fully cooperate with the length of the paper, so it can be suitable for dust protection of various papers. However, after the paper box is used for a long time, the inside of the paper box needs to be cleaned to prevent the accumulated impurities inside from affecting the normal operation of the printer. The paper box dust cover slides with the paper box through a guide rail, which makes it inconvenient to separate the paper box dust cover from the paper box, which hinders cleaning.

Example 1

[0029] A convenient dustproof structure, such as Figures 1 to 6As shown, it includes a paper box 2 that slides with the printer body 1, and connecting seats 3 are relatively fixed on both sides of the outer wall of one side of the printer body 1, and the connecting seat 3 is located above the paper box 2. The two connecting seats 3 are rotatably connected to the same dust cover 4 on the opposite side, and the other end of the dust cover 4 is fixed to the paper box 2 through a connecting component 7. The connecting component 7 includes a card slot 12 and a cavity 14. The card slot 12 is opened on the outer wall of one side of the dust cover 4, and an avoidance groove 13 is opened at the bottom end of the card slot 12. The cavity 14 is opened on one side of the top of the paper box 2, and a slide bar 15 is fixed to the inner wall of the cavity 14. Fixed hooks 16 are slidably connected to the outer walls of the slide bar 15 at both ends, and one end of the fixed hook 16 is limitedly matched with the card slot 12, and a limit spring is sleeved on the outer wall of the slide bar 15 17, the two ends of the limit spring 17 are connected with two fixed hooks 16, the outer wall of the top end of the paper box 2 is provided with a slide groove 18, the bottom end of the slide groove 18 is connected with the cavity 14, the inner wall of the slide groove 18 is slidably connected with a push rod 19, and the bottom end of the push rod 19 is connected with the fixed hook 16, the outer wall of one side of the printer body 1 is provided with a storage groove 5, the inner wall of the top end of the storage groove 5 is fixed with an elastic protrusion 6, the elastic protrusion 6 is limitedly matched with the dust cover 4, the dust cover 4 includes a plurality of U-shaped plates 8 and a tension spring 10, the outer wall of one side of the U-shaped plate 8 is provided with a connecting groove 9, another U-shaped plate 8 is slidably connected with the inner wall of the connecting groove 9, one end of the tension spring 10 is fixed to the inner wall of the connecting groove 9, and the other end of the tension spring 10 is connected to another U-shaped plate 8.

[0030] When the paper box 2 is stretched, the dust cover 4 is taken out from the storage slot 5, and one end of the dust cover 4 is pulled to make the multiple U-shaped plates 8 move relative to each other. The tension spring 10 is stretched so that the overall length of the dust cover 4 can cover the length of the paper box 2 after stretching, and the two push rods 19 are pushed relative to each other to drive the fixed hook 16 to move relative to each other along the slide rod 15. The limit spring 17 is compressed. At this time, the dust cover 4 and the paper box 2 are closed, and the fixed hook 16 enters the card slot 12 through the avoidance slot 13. The push rod 19 is released, and the limit spring 17 pushes the fixed hook 16 to reset and the dust cover 4 is stuck. When the dust cover 4 is no longer needed to cover the paper box 2, the dust cover 4 is retracted and stored in the storage slot 5, and the elastic protrusion 6 limits the dust cover 4.

[0031] By providing the connecting seat 3, the dust cover 4 and the connecting assembly 7, since the dust cover 4 and the paper box 2 are two independent entities, when the paper box 2 is pulled out for cleaning, the dust cover 4 and the paper box 2 are separated and stored in the storage groove 5, which will not cause any obstacle to the cleaning and is convenient for cleaning the paper box 2.

[0032] By providing the storage groove 5 and the elastic protrusion 6, when the dust cover 4 is no longer needed to cover the paper box 2, the dust cover 4 is retracted and stored in the storage groove 5, and the elastic protrusion 6 limits the dust cover 4, so that the dust cover 4 is easily stored. Example 2

[0033] A convenient dustproof structure, based on the embodiment 1, this embodiment makes the following improvements: Figure 3 As shown, a magnet 11 is fixed to one side of the inner wall of the connecting groove 9, and another magnet 11 is fixed to the outer wall of one side of the U-shaped plate 8 slidably connected to the connecting groove 9. The two magnets 11 are arranged opposite to each other, and the magnetic poles of the two magnets 11 are the same.

[0034] When the tension spring 10 pulls the U-shaped plate 8 to retract into the connecting groove 9, the repulsive force between the two magnets 11 generates damping on the U-shaped plate 8, reducing the speed of the U-shaped plate 8, so that the retraction process of the dust cover 4 is stable and smooth.

[0035] By providing the magnets 11, when the U-shaped plate 8 contracts toward the inside of the connecting groove 9, the repulsive force between the two magnets 11 generates damping on the U-shaped plate 8, thereby reducing the speed of the U-shaped plate 8 and making the contraction process of the dust cover 4 stable and smooth.

[0036] Working principle: When the paper box 2 is stretched, the dust cover 4 is taken out from the storage slot 5, and one end of the dust cover 4 is pulled to make the multiple U-shaped plates 8 move relatively, and the tension spring 10 is stretched so that the overall length of the dust cover 4 can cover the length of the stretched paper box 2, and the two push rods 19 are pushed relative to each other, driving the fixed hook 16 to move relatively along the slide rod 15, and the limit spring 17 is compressed. At this time, the dust cover 4 and the paper box 2 are closed, and the fixed hook 16 enters the card slot 12 through the avoidance slot 13, and the push rod 19 is released. The positioning spring 17 pushes the fixing hook 16 to reset and lock the dust cover 4. When the dust cover 4 is no longer needed to cover the paper box 2, the tension spring 10 pulls the dust cover 4 to retract and stores the retracted dust cover 4 in the storage groove 5, and the elastic protrusion 6 limits the dust cover 4. In the process of the tension spring 10 pulling the U-shaped plate 8 to retract into the connecting groove 9, the repulsive force between the two magnets 11 generates damping on the U-shaped plate 8, reducing the speed of the U-shaped plate 8, so that the retraction process of the dust cover 4 is stable and smooth.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
