[0002] Correction tape is a kind of stationery with correction function, mainly including correction tape and correction tape box for installing correction tape, wherein the correction tape box includes a box body and a tape head. Different types of correction tapes in related technologies include fixed and movable tape heads. Fixed tape heads require users to manually adjust the matching angle between the tape head and the text to be corrected. If the matching angle is not appropriate, the correction tape will not fit the text to be corrected, the correction tape will be skewed, or the correction tape will break during correction.

[0003] The movable belt head can automatically adjust the matching angle very well, which greatly avoids the above undesirable phenomena. There are roughly two types of movable belt head structures: the first type uses plastic elastic deformation, which is similar to a cylinder with a fixed tail. The head is used to twist the plastic body to achieve the mobility of the belt head and limit the swing angle of the belt head; the second type uses the rear end of the belt head body to make a cylinder to achieve the mobility of the belt head, and a limiting rib is set to limit the swing angle of the belt head. The above movable belt heads have complex structures and low reliability. Utility Model Content

[0061] like Figures 1 to 4 As shown, the correction tape box 1 of the present application includes a box body 10 and a tape head 11. The box body 10 includes a space 100, and the space 100 has an opening 101 at one end of the box body 10. At least two mounting posts 103 are arranged in the space 100 and close to the opening 101. The tape head 11 is arranged in the opening 101 and extends into the space 100. The tape head 11 has at least two first concave arc surfaces 110, and the two first concave arc surfaces 110 are respectively mounted in cooperation with the mounting posts 103 to mount the tape head 11 in the opening 101. Along the axial direction of the mounting post 103, the distance between the two ends of the first concave arc surface 110 and the mounting post 103 is greater than the distance between the center of the first concave arc surface 110 and the mounting post 103.

Figure 4 , the distances between the two ends of the first concave arc surface 110 and the mounting post 103 are equal. In some other embodiments, the distances between the two ends of the first concave arc surface 110 and the mounting post 103 are not equal, for example, the distance between the end of the first concave arc surface 110 close to the box body 10 and the mounting post 103 can be greater or less than the distance between the other end of the first concave arc surface 110 away from the box body 10 and the mounting post 103. This design can make the swing angle of the correction tape head 11 more diversified, can meet diverse needs, and the distances between the two ends of the first concave arc surface 110 and the mounting post 103 are not equal, which can flexibly adjust the swing angle of the tape head 11.

[0064] Figure 6 The maximum swing angle α of the tape head 11 in the box body 10 is shown, that is, after one end of the first concave arc surface 110 abuts against the mounting post 103, the distance between the other end of the first concave arc surface 110 and the mounting post 103 is the largest. In this embodiment, the maximum swing angle α is 8 degrees, which can also be adjusted according to actual needs. Figure 6 The swing in one direction is shown. In some other embodiments, the swing in another direction may also be shown. Figure 6 , the swing in the other direction can be Figure 6 One end of the first concave arc surface 110 abutting against the mounting post 103 moves downward to reach a position with the maximum distance from the mounting post 103 (similar to Figure 6 The distance between the other end of the first concave arc surface 110 and the mounting column 103 is the largest. Figure 6 The other end of the bracket that is the longest distance from the mounting post 103 will abut against the mounting post 103. This is a swing in the other direction.

[0065] In this embodiment, if Figures 7 to 9 As shown, the tape head 11 includes a nozzle 200, a connecting portion 201 and a mounting portion 203, wherein the connecting portion 201 connects the nozzle 200 and the mounting portion 203, at least two first concave arc surfaces 110 are arranged opposite to each other on the mounting portion 203, the connecting portion 201 is installed on the opening 101, and the nozzle 200 extends out of the connecting portion 201. The nozzle 200 is mainly used to install the correction tape body and realize the complete fit between the correction tape body and the text paper surface during use. The mounting portion 203 is provided with a first concave arc surface 110, which cooperates with the mounting column 103 of the box body 10 to realize the fixation of the tape head 11 and the swinging of the tape head 11 and also can limit the swinging angle of the tape head 11.

[0066] In this embodiment, the mounting portion 203 has a bottom surface 32 and a top surface 31, both of which are parallel to the axis of the mounting column 103, and the first concave arc surface 110 is respectively arranged on the top surface 31 and the bottom surface 32; the two first concave arc surfaces 110 have the same shape, and the projections of the two first concave arc surfaces 110 on the bottom surface 32 are staggered or overlapped. The two first concave arc surfaces 110 are respectively arranged on the top surface 31 and the bottom surface 32 of the mounting portion 203, so that the tape head 11 can be firmly fixed, and the mounting columns 103 on the top surface 31 and the bottom surface 32 can cooperate with the first concave arc surface 110 to realize the swing of the tape head 11, without interference or other structures that restrict the swing of the tape head 11, which is conducive to the correction tape to automatically adjust the contact and matching angle between the tape head 11 and the correction text. The projections of the two first concave arc surfaces 110 on the bottom surface 32 are staggered, which can enhance the strength of the mounting portion 203.

[0067] In this embodiment, the first concave arc surface 110 is arranged at the portion of the mounting portion 203 close to the connecting portion 201, and the mounting portion 203 further includes at least two second concave arc surfaces 120, and the second concave arc surfaces 120 are arranged at the portion of the mounting portion 203 away from the connecting portion 201. The arrangement of the second concave arc surfaces 120 can further strengthen the fixing degree of the tape head 11 in the box body 10. The first concave arc surface 110 is arranged at the portion of the mounting portion 203 close to the connecting portion 201, and the second concave arc surface 120 is arranged at the portion of the mounting portion 203 away from the connecting portion 201; in this way, the first concave arc surface 110 and the second concave arc surface 120 can support each other, which can not only make the installation of the tape head 11 more stable, but also make the first concave arc surface 110 and the second concave arc surface 120 cooperate with the mounting column 103 to realize the swing of the tape head 11.

[0068] In this embodiment, if Figure 5 As shown, the second concave arc surface 120 is respectively installed in cooperation with the mounting column 103, and along the axial direction of the mounting column 103, the distance between the two ends of the second concave arc surface 120 and the mounting column 103 is greater than the distance between the center of the second concave arc surface 120 and the mounting column 103. The second concave arc surface 120 is used to cooperate with the mounting column 103, and along the axial direction of the mounting column 103, the distance between the two ends of the second concave arc surface 120 and the mounting column 103 is greater than the distance between the center of the second concave arc surface 120 and the mounting column 103, so that the mounting column 103 can swing in the second concave arc surface 120, so as not to interfere with the swing of the tape head 11 achieved by the first concave arc surface 110, and the second concave arc surface 120 can also provide a similar function to the first concave arc surface 110, and jointly realize the automatic adjustment of the tape head 11 and the correction of the contact and cooperation angle of the text.

[0069] In this embodiment, the distances between the two ends of the second concave arc surface 120 and the mounting column 103 are equal or unequal. Figure 5, the distances between the two ends of the second concave arc surface 120 and the mounting column 103 are equal. In some other embodiments, the distances between the two ends of the second concave arc surface 120 and the mounting column 103 are not equal, for example, the distance between the end of the second concave arc surface 120 close to the box body 10 and the mounting column 103 can be greater than or less than the distance between the other end of the first concave arc surface 110 away from the box body 10 and the mounting column 103. This design can make the swing angle of the correction belt head 11 more diversified and can meet diverse needs, and the distances between the two ends of the second concave arc surface 120 and the mounting column 103 are not equal, so that the second concave arc surface 120 and the first concave arc surface 110 can support each other and flexibly adjust the swing angle of the belt head 11.

[0070] In this embodiment, the shapes of the two second concave arc surfaces 120 are the same as the shapes of the two first concave arc surfaces 110. The same shapes can simplify the processing steps, which is beneficial to improving production efficiency and reducing costs. In this embodiment, the projections of the two second concave arc surfaces 120 on the bottom surface 32 overlap (see Fig. 9 In some other embodiments, the projections of the two second concave arc surfaces 120 on the bottom surface 32 are staggered.

[0071] Fig.10 It is a CC stepped cross-sectional view of the first concave arc surface 110, wherein the mounting portion 203 between the first concave arc surfaces 110 is thick in the middle and thin at both ends along the axial direction of the mounting column 103, that is, each first concave arc surface 110 is high in the middle and low at both ends relative to the mounting column 103.

[0072] In this embodiment, if Figures 11 to 13 As shown, the box body 10 includes a bottom box 12 and a cover box 13, and the box body 10 is divided into the bottom box 12 and the cover box 13, which is convenient for installation and disassembly, and convenient for installation and replacement of the correction belt body. The mounting post 103 is fixed to the bottom box 12. In this embodiment, there are four mounting posts 103, which can be four independent ones or four connected together in pairs, as long as the installation and swing of the belt head can be achieved. The number of mounting posts 103 can also be multiple, and the concave arc surfaces matched therewith can also be multiple pairs. The situation of the remaining concave arc surfaces is similar to the first concave arc surface 110 and the second concave arc surface 120, which will not be repeated here.

[0073] refer to Fig.11 and Fig.12 The bottom box 12 is also provided with a gear shaft 121 and a gear shaft 2 122 for installing the correction belt body. Fig.13 The cover box 13 is provided with a fixing hole 131 for fixing the push portion 123. A gear end cover 133 matched with the gear shaft 121 and a gear end cover 2 134 matched with the gear shaft 2 122 are also provided. The cover box 13 is also provided with a supporting hole 132 for supporting the mounting column 103.

[0074] In this embodiment, the tape head 11 further includes an end portion 204, which is connected to the mounting portion 203. A push portion 123 is provided in the space 100, and the push portion 123 pushes against the end portion 204 of the tape head 11. The end portion 204 is provided at the end of the tape head 11 extending into the space 100, and pushes against the push portion 123, so that when the correction tape is used, the tape head 11 will not be pushed back into the box body 10 by the thrust of the correction text paper surface on the pressure nozzle 200, thereby ensuring stable contact between the pressure nozzle 200 and the paper surface during use, which is conducive to improving the user experience.

[0075] The present application also provides a correction tape, comprising a correction tape body and the above correction tape box 1, wherein the correction tape body is arranged in the correction tape box 1.

[0076] In this exemplary embodiment, the correction tape box proposed in the present application is described by taking the field of stationery as an example. It is easy for those skilled in the art to understand that in order to apply the relevant design of the present application to other fields, various modifications, additions, substitutions, deletions or other changes are made to the following specific embodiments, and these changes are still within the scope of the principle of the correction tape proposed in the present application.

[0077] It should be noted here that the correction tape box shown in the accompanying drawings and described in this specification is only a few examples in many kinds of correction tape boxes that can adopt the principles of the present application. It should be clearly understood that the principles of the present application are by no means limited to any parts of any details of the correction tape box shown in the accompanying drawings or described in this specification.

[0078] The above is a detailed description of several exemplary embodiments of the correction tape cassette and correction tape proposed in the present application. The following is an exemplary description of the use process of the correction tape cassette and correction tape proposed in the present application.

[0079] The correction tape box 1 proposed in the present application is used together with the correction tape body to form a correction tape. Figures 1 to 13 When using the correction tape of the present application, the user places the pressure nozzle 200 of the tape head 11 on the text paper that needs to be corrected. If the pressure nozzle 200 and the text paper are tilted at a certain angle and are not completely in contact with each other, the first concave arc surface 110 of the tape head 11 is higher in the middle and lower at both ends relative to the mounting post 103, that is, there is a certain gap between the two ends of the first concave arc surface 110 of the tape head 11 and the mounting post 103, so the first concave arc surface 110 can swing relative to the mounting post 103 (see Figure 6 ), thereby driving the lead 11 to swing and completely fit the paper surface of the correction text, thereby automatically adjusting the contact and matching angle between the lead 11 and the correction text.

[0080] In addition, during use, see Figure 6The swing angle of the belt head 11 is limited by the distance between the two ends of the first concave arc surface 110 and the mounting column 103. That is, the swing angle of the belt head 11 can be limited by adjusting the distance between the two ends of the first concave arc surface 110 and the mounting column 103 during manufacturing, without the need to set additional limiting ribs for limiting.

[0081] Through the above-mentioned correction tape box and the use process of the correction tape of this application, it can be concluded that the correction tape box of this application can automatically adjust the contact and matching angle between the tape head and the correction text to improve the user experience. And there is no need to use plastic elastic deformation, nor is there any need to process the rear end of the tape head into a cylinder. The correction tape box of this application can also limit the angle of the tape head swing by adjusting the distance between the two ends of the first concave arc surface and the installation column. The structure is simple.

[0082] In summary, the correction tape box proposed in the present application includes a box body and a tape head.

The tape head is arranged in the opening and extends into the space. The tape head has at least two first concave arc surfaces, and the two first concave arc surfaces are respectively mounted in cooperation with the mounting posts to mount the tape head in the opening. Along the axial direction of the mounting post, the distance between the two ends of the first concave arc surface and the mounting post is greater than the distance between the center of the first concave arc surface and the mounting post.

[0083] The correction tape box proposed in the present application uses a concave arc surface and a mounting column to realize the installation of the tape head and the box body, and the first concave arc surface is high in the middle and low at both ends relative to the mounting column. This design enables the mounting column to swing in the first concave arc surface, thereby realizing the swing of the tape head, and can automatically adjust the contact and matching angle between the tape head and the correction text, thereby improving the user experience. In addition, there is no need to use plastic elastic deformation, nor is there any need to process the rear end of the tape head into a cylinder, and the structure is simple and the processing is easy.

[0084] The correction tape box proposed in the present application can also limit the swing angle of the tape head by adjusting the distance between the two ends of the first concave arc surface and the mounting column. There is no need to set additional limiting ribs for limiting the position. It has a simple structure, high reliability and long service life.
