Description

Technical Field

[0001] This application relates to the field of writing instrument technology, and in particular to a protective sleeve and correction tape. Background Technology

[0002] Correction tape typically includes upper and lower covers, large and small gears, a flexible tape, and a connector. The connector has a nozzle seat at the front, with the nozzle embedded in the nozzle seat. The nozzle seat has an upper cover seat at the rear. The connector has a positioning post. The middle and rear parts of the connector have open slots, with the bottom of the two slots being the small gear shaft hole and the large gear shaft hole, respectively. The large and small gears are respectively fitted into the large and small shaft holes of the connector and fit together. The flexible tape is wound around the two gears at both ends and passes through the nozzle, allowing it to be evenly fed out to cover the pattern on the object, facilitating redrawing.

[0003] When correction tape is not in use, it is usually necessary to protect the flexible tape at the nozzle to prevent it from coming into contact with external structures, which could cause the coating on the flexible tape to peel off. Therefore, correction tape is usually equipped with a protective sleeve to protect the tape head.

[0004] Existing correction tape protective covers mainly include flip-top, insert-top, and snap-on types. Flip-top and insert-top types are the most widely used. Insert-top covers are detachably connected to the correction tape casing, but are prone to loss. Flip-top covers are more convenient and less likely to lose parts, but require more force from the user; excessive force can easily cause breakage at the hinge, damaging the cover. Snap-on types, compared to the former two, have a more complex internal structure, are more complicated to operate, and are more expensive. Utility Model Content

[0067] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0068] In the following description of various exemplary embodiments of the present invention, reference is made to the accompanying drawings, which form part of the present invention, and which illustrate by way of example different exemplary structures, systems, and steps that can implement various aspects of the present invention. It should be understood that other specific solutions to components, structures, exemplary devices, systems, and steps may be used, and structural and functional modifications may be made without departing from the scope of the present invention. Furthermore, although the terms “above,” “between,” “within,” etc., may be used in this specification to describe different exemplary features and elements of the present invention, these terms are used herein only for convenience, such as the orientation according to the examples shown in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of the present invention.

[0069] It is understood that the terms "comprising" and "having," and any variations thereof, in the embodiments of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to such processes, methods, products, or devices.

Similarly, if a device in one of the figures is flipped, an element described as “down” or “bottom” of another element will be oriented “up” or “top” of that element. Thus, the exemplary term “bottom” or “below” can include both “up” and “down” orientations.

[0071] Figure 1 This is an exploded view of the correction tape of this application, as shown below. Figure 1 As shown, the correction tape of this application includes a body 2 and a protective sleeve 1. The end of the body 2 is provided with a tape head 3, and the protective sleeve 1 is used to protect the tape head 3. The protective sleeve 1 includes a sleeve 10 and a telescopic member 20. See also... Figures 2 to 6 , Figures 7 to 12The sleeve 10 has a guide groove 101 on its inner wall at one end. A telescopic member 20 is disposed within the sleeve 10 and has an elastic buckle 201 that slides along the guide groove 101 to allow the telescopic member 20 to extend or retract relative to the sleeve 10. When the telescopic member 20 is extended relative to the sleeve 10, the protective sleeve 1 is in a state of protecting the belt head 3; when the telescopic member 20 is retracted relative to the sleeve 10, the protective sleeve 1 is in a state of exposing the belt head 3. The sleeve 10 of the protective sleeve 1 is connected to the body 2, and the telescopic member 20 can extend or retract relative to the body 2 to protect the belt head 3.

[0072] The protective sleeve 1 of this application is provided with a sleeve 10 and a telescopic component 20. A guide groove 101 is provided on the inner wall of the sleeve 10, and an elastic buckle 201 is provided on the telescopic component 20. The elastic buckle 201 is engaged with the guide groove 101 and can slide back and forth along the guide groove 101, so that the telescopic component 20 can extend and retract relative to the sleeve 10. The structure is simple, the telescopic operation is convenient, and the user's force requirements are not high. If too much force is accidentally applied, it will not cause breakage or other damage.

[0073] In this application, when the telescopic component 20 is extended relative to the sleeve 10, the protective sleeve 1 is in a state of protecting the belt head 3; when the telescopic component 20 is retracted relative to the sleeve 10, the protective sleeve 1 is in a state of exposing the belt head 3. When the belt head 3 is in both protected and exposed states, the telescopic component 20 and the sleeve 10 do not separate, making it less likely to be lost.

[0074] The correction tape of this application is provided with a protective sleeve 1 to protect the tape head 3. The protective sleeve 1 adopts a retractable method to expose and protect the tape head 3. The structure is simple, the operation is easy, the internal structure is not complicated, the cost can be reduced, and it is convenient for the widespread application of correction tape.

[0075] In this design, the radial dimension of the guide groove 101 on the inner wall of the sleeve 10 is smaller than the wall thickness of the sleeve 10. This means the guide groove 101 is only located on the inner wall of the sleeve 10, while the outer wall of the sleeve 10 is intact, and the guide groove 101 is not exposed on the outer wall. The guide groove 101 also limits the sliding distance of the elastic buckle 201 of the telescopic member 20. Buckle grooves 2011 are provided on the upper and lower sides of the elastic buckle 201 on the telescopic member 20. The buckle grooves 2011 are I-shaped grooves, and their design improves the elasticity of the elastic buckle 201.

[0076] In this embodiment, the protective sleeve 1 further includes a top cap 30, which is connected to the telescopic member 20 and moves with the telescopic member 20. The top cap 30 improves the appearance of the correction tape and provides some protection for the telescopic member 20, extending its service life and consequently extending the service life of the protective sleeve 1. The top cap 30 has an "S"-shaped notch that corresponds to the "S"-shaped notch on the sleeve 10. Both the correction tape and the protective sleeve 1 in this application can be made of plastic.

[0077] In this embodiment, the telescopic member 20 is further provided with an elastic boss 202, and the sleeve 10 is provided with a receiving structure to accommodate the elastic boss 202. The elastic boss 202 can move within the receiving structure to lock the position of the telescopic member 20 relative to the sleeve 10. The provision of the elastic boss 202 can lock the sliding position of the telescopic member 20 relative to the sleeve 10, preventing the telescopic member 20 from still sliding relative to the sleeve 10 when it has reached the appropriate position.

[0078] Among them, the upper and lower sides of the elastic boss 202 are respectively provided with boss grooves 2021. The boss grooves 2021 are straight grooves. The setting of the boss grooves 2021 can improve the elasticity of the elastic boss 202.

[0079] In this embodiment, the receiving structure has a first position 1021 and a second position 1022, and the elastic boss 202 can reciprocate between the first position 1021 and the second position 1022. When the elastic boss 202 is located at the first position 1021, the telescopic member 20 is in a position extending relative to the sleeve 10; when the elastic boss 202 is located at the second position 1022, the telescopic member 20 is in a position retracted relative to the sleeve 10. The setting of the first position 1021 and the second position 1022 can lock the position of the telescopic member 20, which is beneficial to improving the user experience.

[0080] In this embodiment, the receiving structure includes a receiving groove 102, and the elastic boss 202 is movable in the receiving groove 102. Each end of the receiving groove 102 is provided with a protruding structure 103, which is used to engage the elastic boss 202 in the receiving groove 102 to lock the position of the telescopic member 20 relative to the sleeve 10. The protruding structure 103 is simple in design and allows the elastic boss 202 to smoothly slide and switch between the first position 1021 and the second position 1022, thereby realizing the extension and retraction of the telescopic member 20.

[0081] In this embodiment, the protrusion structure 103 includes a first protrusion 1031 and a second protrusion 1032; the elastic boss 202 is located between the end of the receiving groove 102 adjacent to the first protrusion 1031 and the first protrusion 1031, then the elastic boss 202 is located at a first position 1021; the elastic boss 202 is located between the end of the receiving groove 102 adjacent to the second protrusion 1032 and the second protrusion 1032, then the elastic boss 202 is located at a second position 1022. Both the first protrusion 1031 and the second protrusion 1032 can be semi-circular arc-shaped protrusions. The first protrusion 1031 has two symmetrical semi-circular arc protrusions, and the second protrusion 1032 also has two symmetrical semi-circular arc protrusions. Both the first protrusion 1031 and the second protrusion 1032 can be integrally formed with the sleeve 10, or they can be formed separately and then attached to the receiving groove 102.

[0082] In this embodiment, a positioning groove 105 is provided on the inner wall of the sleeve 10, and a positioning rib 203 is provided on the outer wall of the telescopic member 20. The positioning rib 203 is located in the positioning groove 105 and can slide along the positioning groove 105. The sliding direction of the positioning rib 203 is the same as the telescopic direction of the telescopic member 20. The positioning groove 105 and the positioning rib 203 enable more stable directional sliding, which helps to improve the stability of the telescopic member 20 during the telescopic process, extends the service life of the telescopic member 20, and improves the stability of the telescopic member 20 during telescopic movement.

[0083] In this embodiment, the sleeve 10 is also provided with an anti-slip structure 106, which can be referred to Figures 1 to 4 The anti-slip structure 106 is located on the outer surface of the sleeve 10 near the top cap 30, allowing the user to easily slide the telescopic component 20 relative to the sleeve 10 by hand. A connecting structure 107 is provided on the inner wall of the end of the sleeve 10 near the correction tape body 2, for connecting the sleeve 10 to the correction tape body 2. The connecting structure 107 is a detachable connecting structure, such as a threaded connection.

[0084] In this embodiment, Figures 13 to 14 The structure of the top cap 30 of this application is shown. One end of the inner wall of the top cap 30 is provided with a mounting groove 301, and the other end of the inner wall of the top cap 30 is provided with a protruding ring 302. See also... Figure 8 , Figures 10 to 12 The telescopic member 20 is provided with a mounting rib 204, which is installed in the mounting groove 301 and can restrict the rotation of the top cap 30 relative to the telescopic member 20. An annular groove 206 is provided at the end of the telescopic member 20 near the top cap 30, and the protruding ring 302 of the top cap 30 is engaged in the annular groove 206 of the telescopic member 20 to achieve the connection between the top cap 30 and the telescopic member 20.

[0085] The protective sleeve 1 of this application also has a second embodiment, wherein the protective sleeve 1 of the second embodiment is related to... Figures 1 to 14 Compared to the protective sleeve 1 of the second embodiment, it has a substantially the same structure in its basic construction. Therefore, in the following description of the protective sleeve 1 of this second embodiment, the description will not be repeated. Figures 1 to 14 The structure has already been described in the implementation method. Additionally, regarding... Figures 1 to 14 The protective sleeve 1 described in the embodiment has the same structure and is labeled with the same reference numerals. Therefore, in the following description of this embodiment, the structure is mainly the same as that of the protective sleeve 1. Figures 1 to 14 The differences between the protective sleeve 1 and the embodiments described herein will be explained. The main difference in the protective sleeve 1 of this second embodiment lies in the housing structure of the sleeve 10. Figures 1 to 14 In one embodiment, the receiving structure is a receiving groove 102. In this second embodiment, see [link to relevant documentation]. Figure 15 The receiving structure has at least two receiving holes 104, which are used to receive the elastic boss 202. There is a gap between the two receiving holes 104, and the elastic boss 202 can move between the two receiving holes 104.

[0086] In this embodiment, the receiving hole 104 includes a first hole 1041 and a second hole 1042; if the elastic boss 202 is located in the first hole 1041, then the elastic boss 202 is located in the first position 1021; if the elastic boss 202 is located in the second hole 1042, then the elastic boss 202 is located in the second position 1022.

[0087] Figure 16 The correction tape in the second embodiment is shown, illustrating a situation where the telescopic member 20, driving the top cap 30, protects the tape head 3. It can be seen that the elastic boss 202 is in the first position 1021. It should be noted that... Figure 1 The correction tape of the first embodiment has a similar structure after installation. Figure 16 The only difference lies in the different containment structures.

[0088] The above is a detailed description of several exemplary embodiments of the correction tape and protective sleeve 1 of this application. The following will provide an exemplary description of the installation and use process of the correction tape and protective sleeve 1 proposed in this application.

[0089] Combined with appendix Figures 1 to 16 The installation and use process of the correction tape and protective sleeve 1 proposed in this application is as follows.

[0090] During installation, first align the elastic buckle 201 of the telescopic component 20 with the guide groove 101 of the sleeve 10. Then, install the telescopic component 20 onto the sleeve 10 from the guide groove 101 end. The elastic boss 202 of the telescopic component 20 will be installed into the receiving structure (receiving groove 102 or receiving hole 104) of the sleeve 10, and the positioning rib 203 of the telescopic component 20 will be installed into the positioning groove 105 of the sleeve 10. At this time, the front end of the telescopic component 20 extends out of the sleeve 10.

[0091] Next, the top cap 30 is installed onto the telescopic member 20 via the protruding ring 302, while the sleeve 10 is installed onto the correction tape body 2 via the connecting structure 107. The portion of the correction tape body 2 located inside the protective sleeve 1 has a large gap with the protective sleeve 1, which ensures smooth telescopic movement of the telescopic member 20.

[0092] When in use, when the correction tape is not in use, the user pushes the telescopic member 20 forward from the anti-slip structure 106 of the sleeve 10. The telescopic member 20 extends out of the sleeve 10, and the elastic boss 202 is in the first position 1021. The protective sleeve 1 protects the tape head 3. When the correction tape needs to be used, the user pushes the top cap 30 and the telescopic member 20 towards the sleeve 10, so that the elastic boss 202 reaches the second position 1022.

[0093] In summary, the protective sleeve proposed in this application includes a sleeve and a telescopic component. A guide groove is provided on the inner wall of one end of the sleeve; the telescopic component is disposed inside the sleeve and is equipped with an elastic buckle that can slide along the guide groove to achieve telescopic movement of the telescopic component relative to the sleeve. When the telescopic component is in the extended position relative to the sleeve, the protective sleeve is in the protected belt head state; when the telescopic component is in the retracted position relative to the sleeve, the protective sleeve is in the exposed belt head state. The structure is simple, the telescopic operation is convenient, and the user's force requirements are not high; with the belt head in both the protected and exposed states, the telescopic component and the sleeve do not separate, making it less likely to be lost.

[0094] The correction tape of this application is equipped with the above-mentioned protective sleeve to protect the tape head. The protective sleeve adopts a retractable method to expose and protect the tape head. The structure is simple, easy to operate, and the internal structure is not complicated, which can reduce costs and facilitate the widespread application of correction tape.
