Technical Field
[0001] This utility model relates to the technical field of printing equipment, specifically a small label printer. Background Technology
[0002] Label printers are devices that use thermal or thermal transfer methods to print barcodes, QR codes, graphics, text, and other image information on labels. They are widely used in POS terminal systems, banking systems, medical instruments, and other fields.
[0003] A common label printer includes a housing, a thermal printhead, a core unit within the housing, and a paper tray cover. Labels are rolled up and placed in the paper tray. The paper tray cover is rotatably mounted on the housing, and a locking block is fixed to the paper tray cover. When the paper tray cover is closed on the paper tray, the locking block presses against the housing, securing the paper tray cover to the paper tray. To open the cover, pinch both sides of the paper tray cover and pull it up to detach it from the paper tray.
[0004] Regarding the aforementioned technical conditions, there is a drawback: when hands are moist or sweaty, the paper tray cover is prone to slipping when pinched to open, making it inconvenient to open the paper tray cover.
[0005] Based on this, the present invention designs a small label printer to solve the above problems. Utility Model Content
[0006] To achieve the above objectives, this utility model provides the following technical solution: a small label printer, including a housing and a paper tray cover disposed on the housing. A vertical mounting groove is provided on the housing, and a lifting plate is inserted into the mounting groove. A retaining spring is fixedly disposed in the housing, located below the lifting plate. A rotating plate is rotatably disposed in the housing, with one end of the rotating plate located between the lifting plate and the retaining spring, the retaining spring abutting against the rotating plate. A retaining groove is provided in the housing, and a retaining block is fixedly disposed on the rotating plate, located in the retaining groove. The paper tray cover is located above the retaining groove. When the lifting plate is pressed down to its lowest height, the retaining block pushes the paper tray cover upwards.
[0007] By adopting the above technical solution, when it is necessary to open the cover, press down the lifting plate so that the lifting plate touches the rotating plate downwards, and the end of the rotating plate away from the lifting plate tilts upwards so that the contact block touches the paper tray cover upwards until the paper tray cover is no longer stuck in the paper tray. There is no need for a person to hold the paper tray cover, thus achieving the effect of conveniently opening the paper tray cover.
[0008] Preferably, an anti-detachment block is fixedly provided on the lifting plate, and the anti-detachment block abuts against the outer shell upward.
[0009] By adopting the above technical solution, the anti-detachment block abuts against the outer shell, which can prevent the lifting plate from detaching from the mounting slot and stabilize the placement of the lifting plate.
[0010] Preferably, a stabilizing cylinder is provided in the outer casing, and the abutting spring is located in the stabilizing cylinder.
[0011] By adopting the above technical solution, the stabilizing cylinder reduces the movement of the resisting spring and stabilizes its placement.
[0012] Preferably, a buffer block is fixedly provided on the upper surface of the lifting plate.
[0013] By adopting the above technical solution, the buffer block cushions the hand when pressed, improving hand comfort.
[0014] Preferably, the outer shell has a connecting groove, a moving block is slidably disposed in the connecting groove, a connecting block and a locking block are fixedly disposed on the moving block, the connecting block is located outside the outer shell, the locking block is located inside the outer shell, the lifting plate has a locking groove, and when the lifting plate is in the lowest position, the locking block is engaged in the locking groove.
[0015] By adopting the above technical solution, after opening the paper tray cover, the moving block is moved to make the locking block engage in the locking slot, so that the abutting block always keeps the paper tray cover in a state of lifting up, preventing the paper tray cover from accidentally closing on the paper tray when it is not filled with paper.
[0016] In summary, this application has the following beneficial technical effects: when it is necessary to open the cover, press down the lifting plate so that the lifting plate touches the rotating plate downwards, and the end of the rotating plate away from the lifting plate tilts upwards so that the contact block touches the paper tray cover upwards until the paper tray cover is no longer stuck in the paper tray. There is no need for a person to hold the paper tray cover, thus achieving the effect of conveniently opening the paper tray cover. Attached Figure Description

[0025] 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.
[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0027] Reference Figures 1-4 A small label printer includes a housing 1 and a paper tray cover 2 disposed on the housing 1. A rotating shaft 22 is rotatably disposed on the housing, and the paper tray cover 2 is rotatably disposed on the rotating shaft 22. A clamping block 3 is fixedly disposed on the paper tray cover 2. When the paper tray cover 2 is closed on the paper tray 4, the clamping block 3 rebounds and clamps the housing 1 under the pressure of the housing 1. A vertical mounting groove 5 is provided on the housing 1, and a lifting plate 6 is inserted into the mounting groove 5. An anti-collision spring 7 is fixedly disposed in the housing 1 and is located below the lifting plate 6.
[0028] Reference Figures 1-4 A rotating shaft 8 is rotatably mounted in the outer casing 1, and a rotating plate 9 is fixedly mounted on the rotating shaft 8. A limiting plate 10 is fixedly mounted in the outer casing 1, and a limiting groove 11 is formed on the limiting plate 10. The rotating plate 9 is located in the limiting groove 11, which can reduce the movement of the rotating plate 9. One end of the rotating plate 9 is located between the lifting plate 6 and the abutting spring 7. The abutting spring 7 abuts against the lower side of the rotating plate 9. An abutting groove 12 is formed in the outer casing 1, and an abutting block 13 is fixedly mounted on the rotating plate 9. The abutting block 13 is located in the abutting groove 12, and the paper tray cover 2 is located above the abutting groove 12.
[0029] Reference Figures 1-4 When it is necessary to open the cover, press down the lifting plate 6 so that the lifting plate 6 touches the rotating plate 9 downwards. The end of the rotating plate 9 away from the lifting plate 6 is tilted upwards, so that the contact block 13 touches the paper compartment cover 2 upwards. When the lifting plate 6 moves down to the lowest height, the locking block 3 on the paper compartment cover 2 no longer locks the paper compartment 4. The paper compartment cover 2 can be opened without the need for manual pinching. The process is quick and simple, achieving the effect of conveniently opening the paper compartment cover 2.
[0030] Reference Figures 1-4 An anti-detachment block 14 is fixedly installed on the lifting plate 6. The anti-detachment block 14 abuts against the outer shell 1 upwards, which can prevent the lifting plate 6 from detaching from the mounting groove 5 and stabilize the placement of the lifting plate 6. A buffer block 15 is fixedly installed on the upper surface of the lifting plate 6. In this embodiment, the buffer block 15 is made of soft silicone. When pressed, the buffer block 15 cushions the hand and improves the comfort of the hand.
[0031] Reference Figures 1-4 A stabilizing cylinder 16 is provided in the outer casing 1, and the resisting spring 7 is located in the stabilizing cylinder 16. The stabilizing cylinder 16 reduces the movement of the resisting spring 7 and stabilizes the placement of the resisting spring 7.
[0032] Reference Figures 1-5 The outer casing 1 has a connecting groove 17, in which a moving block 18 is slidably disposed. A connecting block 19 and a locking block 20 are fixedly disposed on the moving block 18. The connecting block 19 is located outside the outer casing 1, and the locking block 20 is located inside the outer casing 1. The lifting plate 6 has a locking groove 21. After the paper tray cover 2 is opened, when the lifting plate 6 is in the lowest position, the moving block 18 is moved toward one side of the lifting plate 6, so that the locking block 20 is locked in the locking groove 21 to block the lifting plate 6. This keeps the abutting block 13 in the state of lifting the paper tray cover 2, preventing the paper tray cover 2 from accidentally touching and closing onto the paper tray 4 when it is not filled with paper.
[0033] The implementation principle of this embodiment is as follows: When it is necessary to open the cover, press down the lifting plate 6 so that the lifting plate 6 touches the rotating plate 9 downwards, and the end of the rotating plate 9 away from the lifting plate 6 tilts upwards, so that the contact block 13 touches the paper compartment cover 2 upwards. When the lifting plate 6 moves down to the lowest height, the locking block 3 on the paper compartment cover 2 no longer locks the paper compartment 4. The paper compartment cover 2 can be opened without the need for a person to pinch it. The process is quick and simple, achieving the effect of conveniently opening the paper compartment cover 2.
