Description

Technical Field

[0001] This patent relates to the field of stationery products, and in particular to a correction device with a combined lead. Background Art

[0002] Correction tape is a commonly used writing correction device similar to correction fluid. It is applied on paper to cover wrong characters, and can be rewritten immediately, providing convenience for learning and work. Correction tape in the prior art is usually made of a layer of chemically synthesized correction film attached to a base tape. When in use, the layer of chemically synthesized correction film is separated from the base tape and covered on the writing surface of the paper that needs to be corrected to achieve the correction effect.

[0003] At present, most correction tapes on the market usually use integral plastic tape heads. When the mold processing and injection molding process are unstable, the plastic tape heads will have a certain amount of deformation during the processing. In addition, assembly errors are prone to occur during the production and assembly process, and users often fail to restore the tape to a complete correction device when replacing the tape core. Secondly, during use, the mouth of the plastic tape head is prone to wear. After wear, the tape does not fit well, and it is easy to produce bubbles, warping, and other conditions that affect use. It is easy to deform and shake during use, which greatly reduces the user experience. Therefore, taking advantage of the characteristics of metal sheets that are not easy to deform and have good fit, it is necessary to develop a correction device that integrates the metal sheet and the plastic tape head base, is easy to install, and has a fool-proof design. Utility Model Content

[0004] In order to reduce the wear of the correction belt head during use, improve the fit and stability when cutting the belt, and improve manufacturing efficiency, this patent provides the following technical solutions:

[0005] A correction device with a combined belt head comprises a combined belt head, a shell, a belt core and a gear assembly. The combined belt head comprises a belt head base and a metal sheet installed on the belt head base.

[0006] Furthermore, the metal sheet is provided with a first fool-proofing mechanism.

[0007] Furthermore, the combined belt head also includes a plastic mounting frame, and the metal sheet is mounted on the belt head base through the plastic mounting frame.

[0008] Furthermore, the metal sheet has a positioning hole, and the plastic mounting frame has a positioning boss corresponding to the positioning hole. The positioning hole and the positioning boss are circular, triangular, elliptical, square, polygonal or asymmetric fool-proof shapes.

[0009] Furthermore, the plastic mounting frame is composed of an embedded cover and a cover plate connected by a hinge. The embedded cover is provided with a positioning boss. The embedded cover and the cover plate can be opened and closed by the hinge. When the metal sheet is positioned on the embedded cover, the cover plate is closed to fix the metal sheet.

[0010] Furthermore, the embedded cover and / or the cover plate has a first locking mechanism, and the head base has a guide groove and a second locking mechanism. When the metal sheet is positioned on the embedded cover and the cover plate is closed, the metal sheet assembly consisting of the metal sheet and the plastic mounting frame is inserted into the interior of the head base along the guide groove, and the first locking mechanism and the second locking mechanism are interlocked; the plastic mounting frame has a second anti-foolproofing mechanism corresponding to the first anti-foolproofing mechanism.

[0011] Furthermore, the plastic mounting frame can be pivotally set on the head base, and a first locking mechanism is set on the plastic mounting frame, and a second locking mechanism is set on the head base. When the metal sheet is positioned in the embedded cover and forms a metal sheet assembly, the first locking mechanism and the second locking mechanism are interlocked to fix the metal sheet after the plastic mounting frame is closed; the head base has a second anti-foolproofing mechanism corresponding to the first anti-foolproofing mechanism.

[0012] Furthermore, a first locking mechanism is provided on the metal sheet, and a guide rail groove, a second locking mechanism and a second anti-foolproofing mechanism corresponding to the first anti-foolproofing mechanism are provided on the head base. After the metal sheet is inserted into the head base along the guide rail groove, the first locking mechanism and the second locking mechanism are interlocked.

Then, the cover plate 1211 is rotated along the hinge 1213 until it completely overlaps with the embedded cover 1216, and the assembled plastic mounting frame 1210 forms two side edges 1219a and 1219b.
