Detailed Implementation
[0031] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0032] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0033] Reference Figures 1-7 A cover structure for a small label printer includes a printer housing 1 and a protective cover 2 disposed on the housing 1. The protective cover 2 is rotatably disposed on a paper tray 3 via a hinge shaft 20. The protective cover 2 closes onto the opening of the paper tray 3. A silicone abutment layer is disposed on the opening of the paper tray 3, which abuts against the protective cover 2 when the protective cover 2 is closed, thereby fixing the protective cover 2. The protective cover 2 is used to protect the label paper inside the paper tray 3.
[0034] Reference Figures 1-7 A support plate 4 is fixedly installed in the outer shell 1, and a rotating plate 5 is rotatably installed on the support plate 4. A contact block 6 is fixedly installed on one end of the rotating plate 5 near the center of the support plate 4. The contact block 6 is integrally formed with the rotating plate 5. A contact block 7 is fixedly installed on the protective cover 2. A contact opening 8 is provided on the outer shell 1. A pressing opening 9 is provided on the outer shell 1. A moving block 10 is inserted into the pressing opening 9. A guide groove 11 is provided on the outer shell 1. The guide groove 11 communicates with the pressing opening 9. A guide block 12 is fixedly installed on the moving block 10. The guide block 12 is located in the guide groove 11. When moving up and down, the guide block 12 can stabilize the movement of the moving block 10 while preventing the moving block 10 from falling off upward.
[0035] Reference Figures 1-7 The lower side of the movable block 10 abuts against the end of the rotating plate 5 away from the abutting block 6. The support plate 4 is located between the movable block 10 and the abutting block 6. When it is necessary to open the protective cover 2, the movable block 10 is pressed down, and the movable block 10 abuts against the rotating plate 5 downward, causing the rotating plate 5 to rotate and causing the abutting block 6 at the other end to tilt upward, thus lifting the protective cover 2. It is not necessary to manually grasp the protective cover 2 to open it, achieving the effect of conveniently opening the protective cover 2.
[0036] When the protective cover 2 is closed, the contact block 7 enters the contact port 8 and abuts against the contact block 6. When the contact block 6 is pressed down, the rotating plate 5 rotates. The end of the rotating plate 5 near the moving block 10 tilts upward, lifting the moving block 10 and allowing it to return to its original position. There are two rotating plates 5, and a connecting rod 13 is fixedly connected between them. The two rotating plates 5 are located on both sides of the printer. The contact blocks 6 on the two rotating plates 5 are close to the outer edge of the protective cover 2. When one of the rotating plates 5 rotates, it drives the other rotating plate 5 to rotate together through the connecting rod 13. When the protective cover 2 is opened, the two rotating plates 5 rotate simultaneously, allowing the two contact blocks 6 to lift the protective cover 2 at the same time. This stabilizes the rotation of the rotating plates 5 while preventing only one side of the protective cover 2 from being lifted, thus allowing the cover to open more fully.
[0037] Reference Figures 1-7 The movable block 10 has a vertically formed insertion interface 14, into which a plug block 15 is inserted. In this embodiment, the plug block 15 is a silicone block. When the plug block 15 is inserted into the insertion interface 14, the silicone plug block 15 locks the insertion interface 14. A contact plate 16 is fixedly provided on the plug block. The contact plate 16 is integrally formed with the plug block. When it is necessary to clean the movable block 10 and the contact plate 16, the plug block is pulled out from the insertion interface 14 to facilitate cleaning. The contact plate 16 has an anti-slip groove 18. When pressing, the anti-slip groove 18 increases hand friction and reduces hand slippage.
[0038] Reference Figures 1-7The outer casing 1 has a mating groove 17, which communicates with the pressing port 9. The contact plate 16 is located in the mating groove 17, which improves the overall aesthetics of the outer casing 1.
[0039] Reference Figures 1-7 An mounting plate 19 is fixedly installed on the outer shell 1. When the protective cover 2 is closed, the lower surface of the rotating plate 5 near the contact block 6 contacts the mounting plate 19. The mounting plate 19 supports the rotating plate 5 to prevent the rotating plate 5 from running and making noise when the protective cover 2 is closed.
[0040] The implementation principle of this embodiment is as follows: When it is necessary to open the protective cover 2, press down the moving block 10, the moving block 10 touches the rotating plate 5 downward, and the rotating plate 5 rotates, causing the other end of the contact block 6 to tilt upward. The two contact blocks 6 push the contact block 7 upward, thereby fully lifting the protective cover 2. It is not necessary to manually grasp the protective cover 2 to open it, thus achieving the effect of conveniently opening the protective cover 2.
