Description

Technical Field

[0001] The utility model belongs to the technical field of printers, and particularly relates to a portable desktop label and bar code printing device. Background Art

[0002] Portable label and bar code printers are widely used in office fields such as warehouse management, express delivery, and traffic police law enforcement because of their small size and portability. When classifying, making remarks, and labeling items, it is necessary to use attachable labels for operation. To label information on the labels, a label printer is required. When the existing label printers are in use, they generally can only use label rolls with a fixed width. Otherwise, the label roll will shake inside the body, making it difficult to print labels.

[0003] Based on this, the utility model provides a portable desktop label and bar code printing device to solve the above problems. Summary of the Utility Model

[0032] Referring to Figures 1-4 , one embodiment of the present utility model provides a portable desktop label and barcode printing device, including:

[0033] A printer body 100 and an elastic clamping assembly 200;

[0034] A display screen 300 and keys 400 are provided on the upper surface of the printer body 100. Through the display screen 300 and the keys 400, it is convenient to adjust the printing content; mounting grooves 110 are symmetrically provided on both sides of the interior. Through the setting of the mounting grooves 110, the elastic clamping assembly 200 can be supported; and a flip cover plate 500 is provided at the end of the printer body 100. One end of the flip cover plate 500 is rotatably connected to the printer body 100 through a pin shaft to open or close the interior of the printer body 100 for replacing the label roll 600. Several saw teeth 510 are provided at the other end of the flip cover plate 500. Through the setting of the saw teeth 510, the printed labels can be cut off.

[0035] The elastic clamping assemblies 200 are two groups, and one ends of the two groups of elastic clamping assemblies 200 are respectively installed in the installation grooves 110, and the two groups of elastic clamping assemblies 200 are on the same axis; the ends of the two groups of elastic clamping assemblies 200 away from the installation grooves 110 are arranged oppositely to clamp the label roll 600 placed inside the printer body 100. Specifically: The elastic clamping assembly 200 is composed of a sleeve 210, a connecting block 220, a support shaft 230 and a first elastic member 240; one end of the sleeve 210 is installed in the installation groove 110, and a limiting groove 211 with an opening is arranged at the end of the sleeve 210 away from the installation groove 110; one end of the connecting block 220 is sleeved in the limiting groove 211 of the sleeve 210 and is connected with the sleeve 210 in a limiting sliding manner, the first elastic member 240 is installed in the limiting groove 211 of the sleeve 210, and one end of the first elastic member 240 abuts against the limiting groove 211, and the other end abuts against the end face of the connecting block 220; the support shaft 230 is fixedly connected with the end of the connecting block 220 away from the limiting groove 211. When in use, the label roll 600 is placed inside the printer body 100, and the two ends of the label roll 600 are supported by the provided support shaft 230; the first elastic member 240 is a spring, and through the provided first elastic member 240, under the action of the elastic force, the connecting block 220 is pressed towards the middle, and through the symmetric connecting blocks 220, the two ends of the label roll 600 are clamped to keep it stable and not easy to shake; when the width of the label roll 600 is slightly larger, the connecting block 220 can retract towards the side under the elastic force of the first elastic member 240 so as to adapt to label rolls 600 of different widths.

[0036] In one embodiment, a second elastic member 120 is arranged in the installation groove 110; one end of the second elastic member 120 abuts against the installation groove 110, and the other end abuts against the end face of the sleeve 210.

[0037] In this embodiment, the second elastic member 120 is also a spring. By arranging the second elastic member 120 in the installation groove 110, the sleeve 210 can also expand and contract to adapt to label rolls 600 of different widths.

[0038] In one embodiment, a plurality of card slots 231 are arranged in a circumferential array on the side surface of the support shaft 230, and an elastic support block 250 and a third elastic member 260 are arranged in each card slot 231;

[0039] One end of the elastic support block 250 is connected with the card slot 231 in a limiting sliding manner, and the other end is arranged outside the card slot 231. One end of the third elastic member 260 abuts against the card slot 231, and the other end abuts against the end face of the elastic support block 250, and the label roll 600 is supported by the elastic support block 250.

[0040] In this embodiment, a plurality of card slots 231 are arranged in a circumferential array on the side surface of the support shaft 230. In this embodiment, four card slots are provided. And a third elastic member 260 and an elastic support block 250 are sequentially arranged on the card slot 231 from the inside to the outside. To prevent the label roll 600 from circumferentially swaying during rotation when the label roll 600 is installed on the support shaft 230 because the inner diameter of the label roll 600 is larger than the diameter of the support shaft 230, the third elastic member 260 is used to push the elastic support block 250 against the inner cylindrical surface of the label roll 600 to support the label roll 600 and prevent the label roll 600 from circumferentially swaying during rotation.

[0041] In one embodiment, one end of the elastic support block 250 close to the axial center of the label roll 600 is designed as an inclined surface.

[0042] In this embodiment, further, one end of the elastic support block 250 close to the axial center of the label roll 600 is designed as an inclined surface to facilitate the installation of the label roll 600.

[0043] In one embodiment, a plurality of arc support blocks 130 are arranged inside the printer body 100.

[0044] In this embodiment, by providing the arc support blocks 130, the label roll 600 can be further supported.

[0045] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
