Technical Field

[0001] This utility model relates to the field of printing equipment, and in particular to a printer cover that is easy to disassemble and assemble. Background Technology

[0002] A printer is an output device that converts electronic documents or images into a physical paper form. It is a key bridge between digital devices such as computers and mobile phones and paper media.

[0003] When printing documents, the cover plate can reduce interference from external light and airflow during the printing process, thereby preventing blurry prints or uneven colors and ensuring printing accuracy.

[0004] Currently, the load-bearing capacity of existing printer covers is approximately 3.5-4 kg. However, after printing a large number of documents, some users often place the printed papers on the printer cover for easy organization, causing the cover to be subjected to pressure exceeding its load-bearing capacity, resulting in damage. When the cover is damaged, subsequent printing often results in black spots and other contaminants, affecting the normal use of documents. Since the cover needs to rotate relative to the printer body, replacing it often requires disassembling the printer housing to remove or insert the cover's pivot. This process exposes some internal printer parts to the air, making them susceptible to contact with external objects and damage. Therefore, a printer cover that is easy to disassemble and assemble is proposed to solve the above problems. Summary of the Invention

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 - Figure 3This utility model provides an embodiment of a printer cover that is easy to install and remove, including a baffle 1 and a connecting plate 2. The baffle 1 is used to block light, airflow, etc. when the printer is in use. A rotating shaft 3 is fixedly connected to the rear side of the connecting plate 2. The connecting plate 2 is rotatably connected to the main body of the printer through the rotating shaft 3. The baffle 1 and the connecting plate 2 are connected by a connecting mechanism 4. The setting of the connecting mechanism 4 makes it easy to install and remove the baffle 1 and the connecting plate 2, thereby ensuring that when the baffle 1 is damaged, the baffle 1 can be directly replaced without disassembling the printer housing to replace the connecting plate 2.

[0020] Reference Figure 2 , Figure 3 and Figure 5 The connecting mechanism 4 includes a slot 41, which is located on the front side of the connecting plate 2. A sliding bar 42 is fixedly connected to the rear side of the connecting plate 2. The sliding bar 42 slides within the slot 41. The sliding direction of the sliding bar 42 relative to the slot 41 is left and right. The front part of the sliding bar 42 is rectangular, and the rear part is cylindrical. The diameter of the cylindrical part of the sliding bar 42 is greater than the thickness of the rectangular part. The shape of the slot 41 is consistent with the shape of the sliding bar 42. By setting the shapes of the sliding bar 42 and the slot 41, it is ensured that when the sliding bar 42 enters the slot 41, the sliding bar 42 cannot be moved out of the slot 41 in the front-back direction.

[0021] Reference Figure 3 - Figure 5 The connecting mechanism 4 also includes a fixing component 43, which includes a slide groove 431. The slide groove 431 is located on the front side of the connecting plate 2, and both the upper and lower sides of the slide groove 431 extend to the outside of the connecting plate 2. A slider 432 is slidably connected to the inner wall of the slide groove 431. The position of the slide groove 431 ensures that the operator can move the slider 432 by pushing the upper surface of the slider 432. The slider 432 is concave in shape, and the concave position of the slider 432 is located on the front side. The height of the concave area of ​​the slider 432 is longer than the diameter of the cylindrical area of ​​the sliding bar 42. The connecting mechanism 4 also includes a insertion groove 4313, which is located on the upper and lower sides of the baffle 1. The rear side of the insertion groove 4313 extends to the outside of the baffle 1. When the sliding bar 42 is fully inserted into the slot 41, the insertion groove 4313 is exactly in front of the slide groove 431.

[0022] Reference Figure 5 - Figure 7A locking block 433 is slidably connected to the inner wall of slider 432. The sliding direction of locking block 433 relative to slider 432 is up and down. A slot 4310 is formed on the inner wall of baffle 1. The shape of slot 4310 is the same as that of locking block 433. A connecting block 434 is fixedly connected to the rear side of locking block 433. The front side of connecting block 434 is set to an arc shape with the same curvature as the outer circumference of locking block 433. A height control groove 435 is formed on the inner wall of connecting block 434. A moving rod 436 is slidably connected to the inner wall of height control groove 435. The sliding direction of moving rod 436 relative to height control groove 435 is back and forth. A rotating rod 437 is rotatably connected to the outer wall of moving rod 436. The middle part of 7 is rotatably connected to the inner wall of slider 432. A cylindrical protrusion is provided in the middle of the rotating rod 437. The cylindrical protrusion is rotatably connected to the inner wall of slider 432. A sliding block 438 is rotatably connected to the end of the rotating rod 437 away from the locking block 433. A pressing block 439 is slidably connected to the upper surface of the sliding block 438. The sliding direction of the sliding block 438 relative to the pressing block 439 is back-to-back. The sliding direction of the moving rod 436 relative to the height control groove 435 is opposite to the sliding direction of the sliding block 438 relative to the pressing block 439. The outer wall of the pressing block 439 is slidably connected to the inner wall of slider 432. The sliding direction of the pressing block 439 relative to slider 432 is up-and-down.

[0023] Reference Figure 5 The fixing component 43 also includes a first magnetic block 4311, which is fixedly connected to the bottom of the card block 433. A second magnetic block 4312 is fixedly connected to the inner wall of the baffle 1 directly below the card slot 4310. The lower magnetic pole of the first magnetic block 4311 and the upper magnetic pole of the second magnetic block 4312 are different. Through the adsorption effect of the first magnetic block 4311 and the second magnetic block 4312, it is ensured that when the slider 432 moves to the front, the card block 433 can enter the card slot 4310 under the adsorption effect.

[0024] Working principle: When using the device, when it is necessary to replace the baffle 1, the user first presses down on the pressing block 439, which causes the pressing block 439 to move downward and drive the rear end of the rotating rod 437 to move downward, which causes the front end of the rotating rod 437 to move upward, thereby driving the locking block 433 to move upward, so the locking block 433 leaves the slot 4310.

[0025] Since the sliding block 438 can move back and forth relative to the pressing block 439, and the moving rod 436 can also move back and forth relative to the height control groove 435, the back and forth displacement generated at the end of the rotating rod 437 during this process will not have any impact.

[0026] After the card block 433 leaves the card slot 4310, the user first moves the slider 432 backward, so that the slider 432 moves to the outside of the insertion slot 4313. Then the staff pushes the baffle 1 to the right, so that the sliding bar 42 can be moved out of the sliding groove 431, and finally the baffle 1 is separated from the connecting plate 2.

[0027] Subsequently, the user takes out the new baffle 1 and inserts its slider 42 into the slot 41 from right to left. After it is fully inserted, the user pushes the slider 432 from back to front, causing it to move forward and enter the insertion slot 4313.

[0028] When the slider 432 enters the insertion slot 4313, the locking block 433 is exactly above the slot 4310. Therefore, under the attraction of the magnetic block 4311, the magnetic block 4311 drives the locking block 433 into the slot 4310, so that the baffle 1 and the connecting plate 2 are reconnected and the connection is stable.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
