Description

Technical Field

[0001] This utility model belongs to the field of panel printer technology, and more specifically, it relates to a button opening mechanism for a panel printer. Background Technology

[0002] A mini panel printer is a compact and portable printing device designed specifically for printing small panel labels and signs. Its small size saves space, making it easy to move and place. It features multiple printing functions, quickly outputting clear text and images. Commonly used in the electronics and communications industries, it prints equipment panel markings and product labels, helping to improve production and management efficiency and meet diverse, small-batch printing needs.

[0003] Based on the above, the inventors have discovered the following problem: when the current panel printer needs to open the cover, it is necessary to operate on the edge of the printhead lever, which requires a long stroke, making the opening process inconvenient.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a button opening mechanism for a panel printer, in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a button-operated cover opening mechanism for a panel printer, thereby solving the problem that opening the cover of current panel printers is not convenient enough.

[0006] The purpose and function of the button opening mechanism for a panel printer of this utility model are achieved by the following specific technical means:

[0007] A button-operated cover opening mechanism for a panel printer includes a panel printer housing, a panel printer flip cover rotatably mounted on the panel printer housing, a printhead holder installed inside the cavity of the panel printer housing, the printhead holder located at the upper edge of the cavity, a printhead installed inside the printhead holder, a printhead opening lever installed on the printhead holder, an opening mechanism also provided on the panel printer housing, and a locking component for cooperative use provided between the printhead and the panel printer flip cover.

[0008] Furthermore, the opening mechanism includes an L-shaped cover-opening lever frame. A cover-opening lever frame button is mounted at one end of the cover-opening lever frame. A groove for placing the cover-opening lever frame button is provided on the panel printer housing. The cover-opening lever frame button is located within the groove. The groove is larger than the cover-opening lever frame button. A cover-opening lever frame pivot is mounted at the right angle of the cover-opening lever frame. A pivot hole for the cover-opening lever frame is provided on one side of the printhead mounting bracket. The pivot is located within the pivot hole. The cover-opening lever frame is positioned on the outside of the printhead mounting bracket. A cover-opening lever frame pressure block is also mounted on the cover-opening lever frame. The pressure block contacts the root of the printhead cover-opening lever.

[0009] Furthermore, the surface of the cover opening lever button is provided with a lock cylinder hole, a lock cylinder is installed in the lock cylinder hole, a lock tongue is installed on the lock cylinder, and the panel printer housing is provided with a lock tongue limiting hole at the corresponding position of the lock tongue, so that the lock tongue can rotate within the lock tongue limiting hole.

[0010] Furthermore, the panel printer housing and panel printer flip cover are made of plastic.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] When in use, this utility model optimizes the position of the lever rotation axis and the pressing position of the handle, so that the cover can be opened easily with only a small pressing stroke. At the same time, the lever principle reduces the required pressing force, giving users a better user experience. Attached Figure Description

[0026] As attached Figure 1 To be continued Figure 8 As shown:

[0027] This utility model provides a button-opening mechanism for a panel printer, including a panel printer housing 12. A panel printer flip cover 13 is rotatably mounted on the panel printer housing 12. The panel printer housing 12 and the panel printer flip cover 13 are existing technologies, and the method of mounting the panel printer flip cover 13 on the panel printer housing 12 is not described in detail. The panel printer housing 12 and the panel printer flip cover 13 are made of plastic. A printhead fixing bracket 7 is installed in the cavity of the panel printer housing 12, and the printhead fixing bracket 7 is located at the upper edge of the cavity. The printhead 11 is installed inside the printhead holder 7. The printhead 11 is rotatably connected to the printhead holder 7 and is reset by a coil spring. Both the printhead 11 and the printhead holder 7 are existing technologies, and the specific connection method will not be described here. The printhead holder 7 is equipped with a printhead opening lever 6. The panel printer housing 12 is also provided with an opening mechanism. A locking component is provided between the printhead 11 and the panel printer flip cover 13 for cooperative use. The locking component is the same as the locking component on existing panel printers, and will not be described here.

[0028] The opening mechanism includes an L-shaped cover-opening lever frame 1. One end of the cover-opening lever frame 1 is fitted with a cover-opening lever frame button 2. A groove for placing the cover-opening lever frame button 2 is provided on the panel printer housing 12. The cover-opening lever frame button 2 is located within the groove. The groove is slightly larger than the cover-opening lever frame button 2 to allow it to be pressed. A cover-opening lever frame pivot 3 is installed at the right angle of the cover-opening lever frame 1. A pivot hole 8 is provided on one side of the printhead fixing frame 7. The pivot hole 3 is located within the pivot hole 8. The cover-opening lever frame 1 is positioned on the outside of the printhead fixing frame 7. A cover-opening lever frame pressure block 4 is also installed on the cover-opening lever frame 1, and the pressure block 4 contacts the root of the printhead cover-opening lever 6.

[0029] When in use, to open the panel printer flip cover 13, press the opening lever button 2. The opening lever button 2 will cause the opening lever 1 to rotate along the opening lever shaft 3, thereby causing the opening lever pressure block 4 on the opening lever 1 to rotate. The opening lever pressure block 4 presses the base of the print head opening lever 6, thereby causing the print head 11 to flip, disengaging the panel printer flip cover 13 and the print head 11, and then the panel printer flip cover 13 can be opened. Since the opening lever pressure block 4 is located at the base of the print head opening lever 6, the print head opening lever 6 only needs to be pressed for a short stroke to open the panel printer flip cover 13. At the same time, the opening lever shaft 3 is the fulcrum, the distance from the opening lever shaft 3 to the opening lever button 2 is the power arm, and the distance from the opening lever pressure block 4 to the opening lever button 2 is the resistance arm. The power arm is greater than the resistance arm, so it is easier to press the opening lever button 2.

[0030] The cover opening lever button 2 has a lock cylinder hole 10 on its surface, a lock cylinder 5 is installed in the lock cylinder hole 10, and a lock tongue 9 is installed on the lock cylinder 5. The panel printer housing 12 has a lock tongue limiting hole 14 at the corresponding position of the lock tongue 9. The lock tongue 9 can rotate within the lock tongue limiting hole 14. When the lock tongue 9 is within the lock tongue limiting hole 14, the cover opening lever button 2 can be locked, thereby locking the cover opening lever 1. When the lock tongue 9 is within the cover opening lever button 2, the cover opening lever button 2 is in the unlocked state, thereby enabling the cover opening operation.

[0031] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
