Description

Technical Field

[0001] This utility model relates to the field of label printing technology, and in particular to an inner frame connection structure for a label printer. Background Technology

[0002] A label printer is a standalone device specifically designed for printing receipts, tickets, or labels. It typically operates by using an external or internal label roll. Employing thermal or heat transfer technology, it quickly generates clear text, barcodes, or simple graphics, making it suitable for scenarios such as retail point-of-sale systems, logistics documents, and restaurant orders.

[0003] The hinge structure of the inner frame of existing label printers is generally achieved by a metal pivot structure. In order to achieve multi-angle adaptation of the hinge, a multi-level hinge structure is usually used. This means that when it is necessary to replace the print head or internal printing consumables, multiple layers of the hinge structure need to be disassembled, which reduces the efficiency of maintenance.

[0004] Therefore, it is urgent to research and develop an inner frame connection structure for a label printer to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this utility model is to provide an inner frame connection structure for a label printer, which can improve the disassembly efficiency of the hinge structure, thereby improving the maintenance efficiency of the label printer.

[0006] To achieve the above objectives, this utility model provides an inner frame connection structure for a label printer, the specific implementation of which is as follows:

[0007] An inner frame connection structure for a label printer includes a base inner frame and a flip-top inner frame. The base inner frame has an insertion hole, and the flip-top inner frame has an insertion post. The insertion post is inserted into the insertion hole, and the insertion post rotates along the circumferential direction of the insertion hole, thereby causing the flip-top inner frame and the base inner frame to rotate relative to each other.

[0008] The outer peripheral wall of the plug and the inner peripheral wall of the plug hole are interference-fitted so that the plug and the plug hole generate opposite hard frictional forces when they rotate relative to each other.

[0009] This utility model discloses an inner frame connection structure for a label printer. Compared with the prior art, it provides a hinge by setting insertion holes on the inner frame of the base and insertion posts on the inner frame of the flip cover. The hinge is achieved by the insertion of the insertion posts and insertion holes. Furthermore, the interference fit between the outer peripheral wall of the insertion post and the inner peripheral wall of the insertion hole generates opposing hard friction forces when the insertion post and insertion hole rotate relative to each other. The hard friction forces are used to position the rotation angle of the inner frame of the flip cover and the inner frame of the base, allowing it to be used at any opening angle. Disassembly between the two can be achieved simply by pulling the insertion post out of the insertion hole, improving the disassembly efficiency of the hinge structure and thus improving the maintenance efficiency of the label printer.

[0010] In some embodiments, a groove is provided on the side of the inner frame of the base facing the inner frame of the flip cover, and the insertion hole is provided on the inner wall of the groove. A connecting plate is provided on the side of the inner frame of the flip cover facing the inner frame of the base, and the insertion post is provided on the connecting plate. The side wall of the connecting plate abuts against the inner wall of the groove.

[0011] The contact between the inner wall of the groove and the side wall of the connecting plate further enhances the hard friction between the two, thereby achieving the rotation angle positioning of the inner frame of the flip cover and the inner frame of the base.

[0012] In some embodiments, a gasket is provided between the outer wall of the connecting plate and the inner wall of the groove, with one side of the gasket abutting against the side wall of the connecting plate and the other side abutting against the inner wall of the groove.

[0013] By placing a gasket between the outer wall of the connecting plate and the inner wall of the groove, direct contact between the two is avoided, which can cause wear during rotation and improve service life.

[0014] In some embodiments, the grooves are located on both sides of the inner frame of the base, the insertion holes are located on the inner walls of the two grooves opposite each other, the connecting plates are located on the inner frame of the flip cover corresponding to the grooves, and the insertion posts are located on the side walls of the two connecting plates opposite each other.

[0015] By incorporating two grooves and two connecting plates, the stability of the hinged structure between the inner frame of the flip cover and the inner frame of the base is improved.

[0016] In some embodiments, the bottom of the groove is arc-shaped so that the connecting plate can rotate within the groove in the circumferential direction of the insertion hole.

[0017] By making the bottom of the groove arc-shaped, interference between the connecting plate and the inner frame of the base is avoided during the rotation of the connecting plate.

[0018] In some embodiments, the inner frame of the flip cover rotates relative to the inner frame of the base to form a first state or a second state, and the connecting plate rotates with the groove along the circumferential direction of the insertion hole to form a first position and a second position.

[0019] In the first state, the connecting plate rotates from the first position to the second position along the circumferential direction of the insertion hole, and a rotation angle is formed between the inner frame of the flip cover and the inner frame of the base, forming an open state;

[0020] In the second state, the connecting plate rotates from the second position to the first position along the circumferential direction of the insertion hole, and the inner frame of the flip cover covers the inner frame of the base, forming a printing channel for label paper to pass through between the inner frame of the flip cover and the inner frame of the base, thus forming a usage state.

[0021] The state switching between the inner frame of the base and the inner frame of the flip cover is achieved by changing the rotation position of the connecting plate, which improves the ease of use and user experience.

[0022] In some embodiments, a positioning groove is provided on the inner frame of the base, and a positioning protrusion is provided on the inner frame of the flip cover. The positioning protrusion is inserted into the positioning groove and positioned in conjunction with the positioning groove.

[0023] By setting a positioning groove on the inner frame of the base and a positioning protrusion on the inner frame of the flip cover, the stability of the inner frame of the flip cover and the inner frame of the base is improved during use by using the positioning protrusion and the positioning groove for positioning.

[0024] Based on the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0025] By setting insertion holes on the inner frame of the base and insertion posts on the inner frame of the flip cover, the inner frame of the flip cover and the inner frame of the base are hinged by the insertion of the insertion posts and insertion holes. The interference fit between the outer peripheral wall of the insertion post and the inner peripheral wall of the insertion hole generates opposite hard friction forces when the insertion post and the insertion hole rotate relative to each other. The hard friction forces are used to position the rotation angle of the inner frame of the flip cover and the inner frame of the base, so that it can be used at any opening angle. Disassembly between the two can be achieved simply by pulling the insertion post out of the insertion hole, which improves the disassembly efficiency of the hinge structure and thus improves the maintenance efficiency of the label printer.

[0035] like Figure 1-3 As shown, the inner frame connection structure of a label printer provided in this embodiment includes a base inner frame 100 and a flip-top inner frame 200. The base inner frame 100 is provided with a plug hole 120, and the flip-top inner frame 200 is provided with a plug post 220. The plug post 220 is plugged into the plug hole 120. The plug post 220 rotates in the circumferential direction of the plug hole 120, causing the flip-top inner frame 200 and the base inner frame 100 to rotate relative to each other.

[0036] The outer peripheral wall of the plug 220 is interference-fitted with the inner peripheral wall of the plug hole 120 so that the plug 220 and the plug hole 120 generate opposite hard friction forces when they rotate relative to each other.

[0037] In some embodiments, a groove 110 is provided on the side of the inner frame 100 of the base facing the inner frame 200 of the flip cover, and the insertion hole 120 is provided on the inner wall of the groove 110. A connecting plate 210 is provided on the side of the inner frame 200 of the flip cover facing the inner frame 100 of the base, and the insertion post 220 is provided on the connecting plate 210. The side wall of the connecting plate 210 abuts against the inner wall of the groove 110.

[0038] The contact between the inner wall of the groove 110 and the side wall of the connecting plate 210 further enhances the hard friction between the two, thereby achieving the rotation angle positioning of the inner frame of the flip cover 200 and the inner frame of the base 100.

[0039] In some embodiments, a gasket is provided between the outer wall of the connecting plate 210 and the inner wall of the groove 110, with one side of the gasket abutting against the side wall of the connecting plate 210 and the other side abutting against the inner wall of the groove 110.

[0040] By placing a gasket between the outer wall of the connecting plate 210 and the inner wall of the groove 110, direct contact between the two is avoided to prevent wear during rotation, thus improving service life.

[0041] In some embodiments, the grooves 110 are located on both sides of the inner frame 100 of the base, the insertion holes 120 are located on the inner walls of the two grooves 110 opposite to each other, the connecting plates 210 are located on the inner frame 200 of the flip cover corresponding to the grooves 110, and the insertion posts 220 are located on the side walls of the two connecting plates 210 opposite to each other.

[0042] By setting two grooves 110 and two connecting plates 210, the stability of the hinge structure of the inner frame of the flip cover 200 and the inner frame of the base 100 is improved.

[0043] In some embodiments, the bottom of the groove 110 is arc-shaped so that the connecting plate 210 can rotate within the groove 110 in the circumferential direction of the insertion hole 120.

[0044] By setting the bottom of the groove 110 to be arc-shaped, interference between the connecting plate 210 and the inner frame 100 of the base is avoided during the rotation of the connecting plate 210.

[0045] In some embodiments, the inner frame 200 of the flip cover rotates relative to the inner frame 100 of the base to form a first state or a second state, and the connecting plate 210 rotates with the groove 110 along the circumferential direction of the insertion hole 120 to form a first position and a second position.

[0046] In the first state, the connecting plate 210 rotates from the first position to the second position along the circumferential direction of the insertion hole 120, and a rotation angle is formed between the inner frame of the flip cover 200 and the inner frame of the base 100, forming an open state;

[0047] In the second state, the connecting plate 210 rotates from the second position to the first position along the circumferential direction of the insertion hole 120, and the flip cover inner frame 200 covers the base inner frame 100, forming a printing channel for label paper to pass through between the flip cover inner frame 200 and the base inner frame 100, thus forming a usage state.

[0048] The state switching between the base inner frame 100 and the flip cover inner frame 200 is achieved by switching the rotation position of the connecting plate 210, thereby improving ease of use and user experience.

[0049] In some embodiments, a positioning groove 130 is provided on the inner frame 100 of the base, and a positioning protrusion 230 is provided on the inner frame 200 of the flip cover. The positioning protrusion 230 is inserted into the positioning groove 130 and positioned and engaged with the positioning groove 130.

[0050] By setting a positioning groove 130 on the inner frame 100 of the base and a positioning protrusion 230 on the inner frame 200 of the flip cover, the stability of the inner frame 200 of the flip cover and the inner frame 100 of the base is improved by using the positioning protrusion 230 and the positioning groove 130 for positioning.

[0051] The inner frame connection structure of the label printer provided in this embodiment, compared with the prior art, provides a hinge by setting a plug hole 120 on the inner frame 100 of the base and a plug post 220 on the inner frame 200 of the flip cover. The plug-in engagement of the plug post 220 and the plug hole 120 realizes the hinge between the inner frame 200 of the flip cover and the inner frame 100 of the base. The interference fit between the outer peripheral wall of the plug post 220 and the inner peripheral wall of the plug hole 120 realizes the opposite hard friction force generated when the plug post 220 and the plug hole 120 rotate relative to each other. The hard friction force is used to position the rotation angle of the inner frame 200 of the flip cover and the inner frame 100 of the base, so that it can be used at any opening angle. Disassembly between the two only requires pulling the plug post 220 out of the plug hole 120, which improves the disassembly efficiency of the hinge structure and thus improves the maintenance efficiency of the label printer.
