By pressing the cover opening button 26 and lifting the upper inner cover 12 of the printer upward, the upper inner cover 12 of the printer is turned upward with the rotating shaft 13 as the axis, so that it is no longer in contact with the lower inner cover 1 of the printer.
[0026] Specifically, the above solution still has some problems in actual use. When taking out the printed paper, it is necessary to hold the buckles on both sides of the printer housing and pull them forward at the same time. For users who frequently use the printer, this operation is rather cumbersome, which increases the operation time and labor intensity and easily causes finger fatigue.
[0027] Therefore, the present invention solves this problem by setting a corresponding structure. A torsion spring is set on the rotating shaft 13. When the printer is closed, it is in the initial state. At this time, the torsion spring is in an elastically compressed state. After printing is completed, the printed paper will fall on the top of the lower inner cover 1 of the printer. When taking out the printed paper, press the cover opening button 26 with one hand and lift the printer outer cover 14 upward. Under the combined action of the torsion spring and the upward lifting of the printer outer cover 14, the upper inner cover 12 of the printer is flipped upward with the rotating shaft 13 as the axis, so that it is no longer in contact with the lower inner cover 1 of the printer. At this time, take out the printed paper on the top of the lower inner cover 1 of the printer with the other hand, and press the printer outer cover 14 downward with one hand to reset the upper inner cover 12 of the printer to prepare for the next printing.
[0028] Embodiment 2 like Figures 2 to 8 As shown, compared with Example 1, another implementation of the present invention is: like Figures 4 to 8As shown, the cover opening assembly of this embodiment further includes a limit plate 21, the limit plate 21 is fixed on the top of the fixed plate, a fixed rod 22 is fixedly connected between the printer outer cover 14 and the fixed plate, the fixed rod 22 is symmetrically arranged at both ends of the fixed plate, a rotating hardware shaft 23 is arranged on the limit plate 21, the limit plate 21 is concave in shape, the rotating hardware shaft 23 slides in the concave groove of the limit plate 21, and a tension spring 24 is fixedly connected between one end of the rotating hardware shaft 23 and the fixed plate; A limiting groove 25 is provided on one side of the printer outer cover 14, and a cover opening button 26 is slidably connected inside the printer outer cover 14. The cover opening button 26 slides on the top of the fixed plate. The cover opening button 26 slides in the limiting groove 25. An arc groove is provided on the top of one end of the cover opening button 26, and the arc groove matches the shape of the rotating hardware shaft 23. A limiting groove 27 is provided through the cover opening button 26, and a guide rod 28 is fixedly connected between the fixed plate and the top of the inner part of the printer outer cover 14.
[0029] Specifically, initially, the tension spring 24 is not deformed, the rotating hardware shaft 23 is located at one end of the limit plate 21 close to the cover opening button 26, and the cover opening button 26 is located at one end of the limit slot 1 25 away from the middle of the printer cover 14; During the cover opening process, first press the cover opening button 26 with one hand, and under the action of the limiting groove 27 and the guide rod 28, the cover opening button 26 moves linearly toward the middle of the printer outer cover 14, thereby driving the rotating hardware shaft 23 to move toward the other end of the limiting plate 21, and driving the tension spring 24 to elastically stretch until the rotating hardware shaft 23 conflicts with the other end of the limiting plate 21. At this time, the printer outer cover 14 is lifted upward so that the printer upper inner cover 12 no longer conflicts with the printer lower inner cover 1, thereby completing the cover opening operation of the printer with one hand.
[0030] like Figure 4 and Figure 6 As shown, the limiting groove 27 described in this embodiment is composed of two semicircular arc grooves and a rectangular groove. The two semicircular arc grooves are respectively connected to the two ends of the rectangular groove. The guide rod 28 passes through the limiting groove 27, and the shape of the guide rod 28 matches the shape of the limiting groove 27.
[0031] Specifically, when the cover opening button 26 moves, the guide rod 28 and the second limiting groove 27 limit the cover opening button 26 so that it can only move in a horizontal linear direction.
[0032] like Figure 3 , Figure 4 and Figures 6 to 8As shown, a locking assembly is provided on the lower inner cover 1 of the printer in this embodiment, and the locking assembly includes a buckle 31. The two ends of the rotating hardware shaft 23 are respectively fixed to the two buckles 31. The fixing rod 22 passes through the middle of the buckle 31. The buckle 31 rotates on the fixing rod 22. A slot 32 is provided on the top of the lower inner cover 1 of the printer. The buckle 31 and the slot 32 are symmetrically arranged. One end of the buckle 31 matches the shape of the slot 32. Through the clamping connection between the buckle 31 and the slot 32, the upper inner cover 12 of the printer is fitted with the lower inner cover 1 of the printer.
[0033] Specifically, initially, the bottom of the buckle 31 is engaged with the slot 32 . During the movement of the rotating hardware shaft 23 , the buckle 31 rotates with the movement of the rotating hardware shaft 23 around the fixed rod 22 , so that the bottom of the buckle 31 is no longer engaged with the slot 32 .
[0034] The present invention presses the cover opening button 26 so that the buckle 31 is no longer engaged with the slot 32, and under the action of the torsion spring and the upward lifting of the printer outer cover 14, the opening of the printer cover is accelerated. By pressing the cover opening button 26 and resetting the printer outer cover 14, the cover opening button 26 is then released, and the cover opening button 26 is reset under the action of the tension spring 24, and the bottom of the buckle 31 and the slot 32 are reset, completing the cover closing operation, making it more convenient and quick to open and close the printer cover. This method simplifies the user's operating steps and makes it more convenient and quick to open and close the printer cover. For users who need to use the printer frequently, the operating steps can be significantly reduced, reducing the time cost of using the printer.
[0035] The present invention controls the buckle 31 and the card slot 32 through the cover opening button 26 to prevent the printer from automatically popping open or one side not being fastened during printing, thereby ensuring the stability of the printer.
[0036] The present invention completes the cover opening operation by pressing the cover opening button 26. Compared with the prior art, the space required for opening the cover is reduced, making the overall volume of the printer more compact and making more effective use of limited space resources.
[0037] The cover opening assembly and the locking assembly of the present invention are simple and easy to understand in structure, which is convenient for daily maintenance and troubleshooting, while reducing the difficulty and cost of maintenance.
[0038] Working principle: After printing is completed, the printed paper will fall on the top of the lower inner cover 1 of the printer. When taking out the printed paper, first press the cover opening button 26 with one hand. Under the action of the limiting groove 27 and the guide rod 28, the cover opening button 26 moves linearly toward the middle of the printer outer cover 14, thereby driving the rotating hardware shaft 23 to move toward the other end of the limiting plate 21, and driving the tension spring 24 to elastically stretch until the rotating hardware shaft 23 contacts the other end of the limiting plate 21. During the movement of the rotating hardware shaft 23, the buckle 31 rotates with the fixed rod 22 as the rotating hardware shaft 23 moves, so that the bottom of the buckle 31 is no longer engaged with the card slot 32, thereby completing the unlocking operation; Under the combined action of the torsion spring and the upward lifting of the printer upper inner cover 12, the printer upper inner cover 12 is turned upward with the rotating shaft 13 as the axis, so that the buckle 31 slides out of the card slot 32, so that the printer upper inner cover 12 is no longer attached to the printer lower inner cover 1, so that the printer outer cover 14 moves upward, and the printer cover opening operation is completed with one hand; At this time, the other hand takes out the printed paper on the top of the lower inner cover 1 of the printer, and then presses down the outer cover 14 of the printer with one hand. Through the above operations, the upper inner cover 12 of the printer is reset to prepare for the next printing.
[0039] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
