Description

Technical Field

[0001] This utility model relates to the field of stationery technology, specifically to a rotary extendable correction tape. Background Technology

[0002] Correction tape is a common stationery item used in daily office and study work to cover up and correct writing errors. Traditional correction tape often features a design where the tip is exposed for extended periods. During storage or transport, the exposed tip can easily scratch other items in the pencil case, causing damage to the tip or breakage of the correction tape, thus affecting its usability.

[0003] To address the issue of head protection, retractable correction tapes have emerged in existing technologies. Common press-type correction tapes typically have complex internal structures, numerous components, and rely on springs for drive, resulting in relatively high assembly and manufacturing costs. Furthermore, many traditional correction tapes are designed for single use; once the correction tape is used up, the entire casing along with the internal mechanism must be scrapped, leading to a waste of resources.

[0004] Therefore, there is indeed a need for a simple, rotating, extendable correction tape that can effectively protect the tape head and support replacement of the replacement core. Utility Model Content

[0005] To address the aforementioned issues, a rotary extension correction tape is provided, which solves the problems of complex structure and inability to replace the correction tape core.

[0006] To address the problems of existing technologies, this utility model provides a rotary extendable correction tape, comprising a mounting base with a vertically extending through groove on its side wall; a sliding seat slidably inserted into the inner cavity of the mounting base, the surface of the sliding seat having an adjusting block protruding therefrom, the adjusting block passing through the through groove and extending to the outer surface of the mounting base; a rotating outer shell rotatably fitted onto the outside of the mounting base, the inner wall of the rotating outer shell having a guide groove; and a correction tape replacement core detachably installed in the inner cavity of the sliding seat, the portion of the adjusting block extending out of the mounting base being slidably accommodated in the guide groove; when the rotating outer shell rotates relative to the mounting base, the guide groove pushes the adjusting block to move along the through groove, causing the correction tape replacement core to extend or retract.

[0007] Preferably, an elastic portion is formed on the surface of the mounting base and below the through groove, and a snap fastener protrudes from the end of the elastic portion.

[0008] Preferably, the inner wall of the rotating housing is provided with a connecting groove extending in the circumferential direction, and the fastener is slidably accommodated in the connecting groove; a limiting area is recessed at one end of the connecting groove, and a stop is protruding on the groove wall of the connecting groove and adjacent to the limiting area; when the correction tape replacement core is fully extended, the fastener passes over the stop and engages in the limiting area.

[0009] Preferably, the stop member has a guide slope on the side away from the limiting area to guide the buckle member to slide into the limiting area; the stop member has a blocking curved surface on the side close to the limiting area, and the elastic part can be elastically deformed to allow the buckle member to disengage through the blocking curved surface.

[0010] Preferably, one end of the guide groove extends to the connecting groove, and the other end of the guide groove has a positioning area for the adjusting block to be engaged; the positioning area and the limiting area are corresponding in position, so that when the adjusting block enters the positioning area, the fastener simultaneously enters the limiting area.

[0011] Preferably, the bottom of the correction tape replacement core is provided with a mounting part, and the bottom of the inner cavity of the sliding seat is provided with a locking elastic element.

[0012] Preferably, there are two adjusting blocks and two through slots, and the two adjusting blocks are accommodated in the corresponding through slots; there are two guide slots, and the two guide slots are arranged in a one-to-one correspondence with the two adjusting blocks.

[0013] The advantages of this utility model compared to the prior art are:

[0014] 1. This utility model uses the guide groove on the inner wall of the rotating outer shell and the through groove on the mounting base to cooperate with each other, so that the external rotational motion is converted into the sliding seat moving up and down in a straight line, thereby extending or retracting the correction tape's scribbling tip. Compared with the complex pressing spring structure, it is simple to use. Furthermore, by utilizing the through groove and guide groove, it avoids the jamming or tilting of the replacement core during the extension and retraction process, resulting in a smoother operating feel.

[0015] 2. This utility model utilizes the elastic part on the mounting base and the stop and limiting area inside the rotating shell. With the correction tape extended into place and the adjustment block sliding into the positioning area, the double locking design can effectively resist the reaction force generated during coating and avoid the problem that the rotary correction tape is prone to automatic retraction when subjected to force.

[0016] 3. This utility model adopts a detachable connection design with the correction tape replacement core and the sliding seat as separate parts. When the correction tape is used up, the user only needs to press the elastic part to remove the outer shell and replace the replacement core, without having to scrap the entire mounting base, sliding seat and rotating shell.

Detailed Implementation

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figures 1-5 As shown, a rotary extension correction tape is mainly composed of a mounting base 1, a sliding seat 4, a rotating outer shell 2, and a correction tape replacement core 3.

[0026] Example 1: In this utility model, the mounting base 1 serves as an internal support component and has a hollow cylindrical structure. Its side wall has a vertically extending through groove 13.

[0027] The sliding seat 4, as an intermediate transmission component, is slidably and coaxially inserted into the inner cavity of the mounting base 1. An adjusting block 5 is integrally protruded on the outer surface of the sliding seat 4. The size of the adjusting block 5 is designed to pass through the through groove 13 and extend to the outer surface of the mounting base 1. The existence of the through groove 13 restricts the sliding seat 4 from rotating relative to the mounting base 1, and only allows it to move up and down along the axial direction.

[0028] The rotating housing 2 serves as an external driving component and is rotatably fitted onto the outside of the mounting base 1. The inner wall of the rotating housing 2 is spirally or obliquely extended with a guide groove 11, and the portion of the adjusting block 5 extending out of the mounting base 1 is precisely slidably accommodated within the guide groove 11.

[0029] The correction tape replacement core 3 is detachably installed in the inner cavity of the sliding seat 4, ensuring that when the correction tape runs out, the user only needs to replace the core without scrapping the entire drive mechanism. The portion of the adjusting block 5 extending out of the mounting base 1 is slidably accommodated in the guide groove 11.

[0030] When the rotating housing 2 rotates relative to the mounting base 1, the guide groove 11 pushes the adjusting block 5 to move along the through groove 13, causing the sliding seat 4 and the correction tape replacement core 3 to extend or retract.

[0031] When the rotating housing 2 is rotated, the adjusting block 5 is restricted to the left and right position by the through groove 13. The side wall of the guide groove 11 on the inner wall of the rotating housing 2 will continuously push the adjusting block 5, forcing the adjusting block 5 to overcome the friction and slide up and down along the through groove 13. The axial movement of the adjusting block 5 directly drives the sliding seat 4 and the correction tape replacement core 3 installed on it to extend outward or retract inward in sync, thereby realizing the extension and retraction switching of the working end of the correction tape.

[0032] Example 2: To address the lack of operational feedback in the prior art, this example incorporates a locking feedback mechanism between the mounting base 1 and the rotating housing 2, as shown in the attached diagram of the specification. Figure 3 and Figure 4 As shown, the surface of the mounting base 1 is located below the through groove 13. The surface of the mounting base 1 is also integrally formed with an elastic part 14. The elastic part 14 has a certain elastic deformation capability and a buckle 15 is protruding from the top end. The buckle 15 faces the rotating housing 2.

[0033] Correspondingly, a connecting groove 8 extending circumferentially is provided on the lower part of the inner wall of the rotating housing 2. The snap fastener 15 on the elastic part 14 is accommodated in the connecting groove 8, which not only connects the rotating housing 2 and the mounting base 1, but also allows the two to rotate relative to each other.

[0034] One end of the connecting groove 8 is recessed with a limiting area 9, and a protruding stop 10 is provided on the groove wall of the connecting groove 8, that is, adjacent to the limiting area 9. When the tape nozzle of the correction tape replacement core 3 is screwed out to the limit position, the buckle 15 will pass over the stop 10 and fall into the limiting area 9 to achieve locking; Embodiment 3: Figure 3As shown, the stop 10 is not a simple rectangular protrusion, but rather a guide slope is formed on the side of the stop 10 away from the contact surface of the limiting area 9 in the rotation direction. When the rotating housing 2 rotates clockwise, the latch 15 of the elastic part 14 can slide smoothly up this slope with less resistance, which guides the latch 15 into the limiting area 9. A blocking surface is formed on the side of the stop 10 near the limiting area 9. The blocking surface can also have a certain curvature protrusion. When the latch 15 falls into the limiting area 9, the blocking surface will effectively block the latch 15. Therefore, the slight vibration or reaction force generated during the correction tape coating process cannot cause the latch 15 to come out, thereby preventing the replacement core from automatically retracting. Only when the user actively applies a counterclockwise rotation of the rotating housing 2 will the elastic part 14 be subjected to force and undergo a large elastic deformation, causing the latch 15 to flip over the blocking surface and retract.

[0035] Example 4: Figure 3 As shown, one end of the guide groove 11 is actually connected to the connecting groove 8, so that during initial assembly, the adjusting block 5 can slide into the guide groove 11 along the connecting groove 8. One end of the guide groove 11 extends to the connecting groove 8, and the other end of the guide groove 11 is provided with a positioning area 12 for the adjusting block 5 to be inserted. The positioning area 12 can be a horizontal or slightly bent groove segment. When the screw drive causes the adjusting block 5 to slide into the upper positioning area 12, the lower elastic part 14 and the fastener 15 also slide into the limiting area 9 at the same time. At this time, the axial position of the adjusting block 5 is restricted by the positioning area 12, and the circumferential rotation of the fastener 15 is restricted by the limiting area 9, ensuring the stability of the correction tape during use.

[0036] Example 5: In order to replace the correction tape replacement core 3, as follows: Figure 2 and Figure 6 As shown, the correction tape replacement core 3 is not directly fixed to the base, but is transferred through the sliding seat 4. The bottom of the correction tape replacement core 3 is provided with a mounting part 6, and the bottom of the inner cavity of the sliding seat 4 is provided with one or more positioning elastic elements 7. When the replacement core needs to be replaced, the user only needs to press the elastic part 14 to release the outer shell lock, remove the rotating outer shell 2, and then forcefully pull out the old replacement core. When installing the new replacement core, the mounting part 6 is inserted into the sliding seat 4, and the positioning elastic element 7 will automatically lock the mounting part 6, realizing quick disassembly and assembly. In order to further facilitate disassembly, the end of the connecting groove 8 away from the limiting area 9 can be provided with a disassembly groove, which is used to facilitate the disengagement of the buckle 15 from the connecting groove 8. It should be noted that if a disassembly groove is provided, the depth of the disassembly groove into the inner wall should be less than the depth of the connecting groove 8.

[0037] Example 6: To prevent the sliding seat 4 from tilting or jamming during movement, such as... Figure 2 and Figure 5As shown in the figure, multiple adjustment blocks 5 and through slots 13 are provided in this embodiment. As shown in the attached figure, two adjustment blocks 5 and two through slots 13 are provided respectively, and they are symmetrically distributed at 180 degrees. The guide slots 11 on the inner wall of the rotating housing 2 are also provided in the same number, which can evenly apply the driving force to both sides of the sliding seat 4, balance the friction, and make the process of rotating out and retracting smoother and more stable. Four, six or eight slots can be provided. The number of connecting slots 8 and the number of elastic parts 14 can both be multiple. It should be noted that multiple connecting slots 8 correspond one-to-one with multiple elastic parts 14.

[0038] Working principle: When correction tape is needed, the other hand rotates the rotating housing 2 clockwise. The guide groove 11 on the inner wall of the rotating housing 2 rotates accordingly. Since the adjusting block 5 passes through the through groove 13 on the mounting base 1 at the same time, it is limited by the through groove 13 and cannot rotate with the rotating housing 2. It can only slide vertically upward along the through groove 13 under the push of the guide groove 11. The rise of the adjusting block 5 drives the sliding seat 4 and the correction tape replacement core 3 installed therein to extend outward synchronously until the tape nozzle is exposed at the end of the rotating housing 2. During the extension process, the elastic part 14 on the mounting base 1 and the buckle 15 at its end are relative to the rotating housing. The inner wall of the correction tape 2 slides within the connecting groove 8. When the correction tape replacement core 3 is about to fully extend into place, the locking member 15 of the elastic part 14 contacts the stop member 10 within the connecting groove 8. Because the side of the stop member 10 facing the locking member 15 has a gentle guide slope, the user only needs to apply slight force, causing the elastic part 14 to elastically deform, allowing the locking member 15 to pass over the stop member 10. Simultaneously, as the locking member 15 passes the stop member 10 and enters the limiting area 9, the adjusting block 5 also slides into the positioning area 12 at the top of the guide groove 11. At this point, the blocking curved surface of the stop member 10 facing away from the limiting area 9 prevents the locking member 15 from retracting, and the positioning area 12 prevents the adjusting block 5 from sliding down. This structure ensures that the correction tape will not automatically retract when applied under pressure.

[0039] When the user needs to retract the device after use, the user rotates the outer shell 2 in the opposite direction, causing the elastic part 14 to deform elastically again. This allows the buckle 15 to overcome the resistance of the stop 10 blocking the curved surface and disengage from the limiting area 9. At the same time, the adjusting block 5 disengages from the positioning area 12. Guided by the guide groove 11, the adjusting block 5 slides down along the through groove 13, causing the sliding seat 4 and the correction tape replacement core 3 to retract into the rotating shell 2 until the elastic part 14 is reset and the adjusting block 5 reaches the bottom of the through groove 13.

[0040] When it is necessary to replace the replacement core, press the elastic part 14 on the mounting base 1 to disengage the buckle 15 from the connecting groove 8 of the rotating housing 2, thereby releasing the axial lock between the housings. The rotating housing 2 can then be pulled upwards. Using the elastic action of the positioning elastic part 7 at the bottom of the sliding seat 4, the old correction tape replacement core 3 can be pulled out and replaced with a new core.

[0041] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
