Description

Technical Field

[0001] This application relates to the field of stationery technology, and more specifically to a pen-shaped coating transfer tool. Background Technology

[0002] Correction tape, also known as a coating transfer tool, is a tool that transfers the coating from a tape onto the surface of another object. Similar to correction fluid, it is applied to paper to cover up mistakes, allowing for immediate rewriting and providing convenience for study and work. Currently, correction tapes come in various styles, including flat, square, round, and pen-shaped. Pen-shaped correction tapes are particularly popular due to their compact size and ease of grip. A correction tape mainly consists of a housing and a replacement core assembly installed inside the housing. Housings are currently available in one-piece and separate types. One-piece housings cannot be disassembled, making it impossible to replace the core assembly, and the correction tape must be discarded along with the housing after use, resulting in significant resource waste. To address the aforementioned issues, a utility model patent with publication number CN215826341U discloses a correction tape, comprising a housing and a core assembly. The core assembly is disposed within the housing, and the lower end of the housing has an opening for the head of the core assembly to protrude. The housing includes a main body portion at the lower part and a detachable upper cover inserted into the top of the main body portion. The core assembly is installed in the main body portion and has a first limiting part at its top. Correspondingly, the upper cover has a second limiting part that can be detachably connected to the first limiting part. When the upper cover is detached from the main body portion, the core assembly is pulled out of the housing under the constraint of the upper cover. In this technical solution, an elastic locking foot is provided on the side of the top cover near the lower edge. Correspondingly, a locking slot is provided at the top edge of the main body to engage with the elastic locking foot. The upper cover and the main body of the shell are disassembled and reassembled by engaging the elastic locking foot with the locking slot, thereby replacing the core component. However, the structural design of this elastic locking foot requires cutting off a portion of the upper cover to provide elasticity for locking and unlocking, and the locking slot needs to be cut out on the shell. The locking structure formed by the elastic locking foot and the locking slot is located on the outer periphery of the overall correction band, which not only causes significant damage to the appearance, but also has a significant impact on the strength of the overall structure and poor structural stability. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a pen-type coating transfer tool, which adds a connector between the shell and the cover, and the connector is detachably connected to the cover. The detachable connection structure is located in the mounting cavity between the shell and the cover, which not only has better aesthetics, but also better overall structural strength and better disassembly and assembly stability.

[0004] This application provides a pen-type coating transfer tool, including a housing, a cover, and a core assembly. The housing and the cover are connected to form a mounting cavity for accommodating the core assembly. A connector is installed in the mounting cavity. The cover has an extension that enters the mounting cavity and is detachably connected to the connector. The connector locks or unlocks the housing and the cover by connecting or disconnecting from the extension. The connector has a switch. The housing has a first opening adapted to the switch, and the switch protrudes through the first opening for unlocking operation.

[0005] In this technical solution, a housing and a cover are connected to form an installation cavity for installing a replacement core assembly. A connector is provided within the installation cavity, and an extension is provided on the cover. When the housing and cover are connected to form the installation cavity, the extension is located within the cavity. The extension is detachably connected to the connector. The cover is inserted into the installation cavity through the extension, and the extension connects to the connector to lock the housing and cover together. A switch is provided on the connector; force on this switch can disengage the connector from the extension, unlocking the housing and cover connection. The addition of a connector between the housing and cover allows for a detachable connection, enabling replacement of the replacement core assembly after use or damage, improving utilization, reducing operating costs, and ensuring a smooth connection. The connection structure between the connector and the extension is located in the mounting cavity between the housing and the cover. This not only improves aesthetics but also enhances overall structural strength, thus improving the stability of the housing and cover during assembly and disassembly. Since the connector is located within the mounting cavity, a first opening is provided on the housing, through which the switch extends into the mounting cavity. This allows the user to press the switch and apply force to unlock the device. Furthermore, the first opening, in conjunction with the switch, confines the connector within the housing, preventing displacement and ensuring greater reliability. In actual use, the user simply needs to press the switch to detach the cover from the housing and insert the extension into the housing to secure it. The structure is simple, reliable, and effortless to assemble and disassemble.

[0006] As an improvement, the connector is provided with a first latch, and the extension is provided with a first latching position adapted to the first latch. The first latch connects with the first latching position to lock the shell and the cover. When the first latch is subjected to force, it disengages from the first latching position to unlock the shell and the cover. In this technical solution, by providing a first latch on the connector and a first latching position on the extension, the extension is connected or disengaged from the connector through the cooperation of the first latch and the first latching position, resulting in a simple and reliable locking structure.

[0007] As an improvement, the first latch is a spring-loaded structure mounted on the connector, and the switch is mounted on the first latch. In this technical solution, the first latch is a spring-loaded structure, which can connect or disengage with the first buckle through elasticity. Furthermore, the switch is mounted on the first latch, and the force applied to the switch causes the first latch to elastically deform, resulting in more efficient and reliable transmission. On the other hand, the connector is an integral structure with high structural strength. Its installation within the mounting cavity ensures a more reliable fit with the cover, further enhancing the structural strength of the housing.

[0008] As an improvement, both the first latch and the first buckle are T-shaped. In this technical solution, both the first latch and the first buckle are T-shaped, resulting in a simple and reliable fit.

[0009] As an improvement, the first latch is provided with a guide slope adapted to the first latch position, and the first latch is inserted into the first latch position through the guide slope. In this technical solution, when the connector and the extension are inserted, the first latch undergoes elastic deformation under force to connect with the first latch position. By providing a guide slope on the first latch, the first latch can enter the first latch position more smoothly under the guidance of the guide slope, making disassembly and assembly easier.

[0010] As an improvement, the replacement core assembly is slidably installed within the mounting cavity. The replacement core assembly is connected to a push-button assembly, which, when subjected to force, drives the replacement core assembly to slide and extend / retract. In this technical solution, by setting a slidable replacement core assembly, the replacement core assembly extends / retracts relative to the housing through sliding. The replacement core assembly is connected to the push-button assembly. When needed, the user applies force to the push-button assembly, causing it to extend relative to the housing. When needing to be stored, the user applies force again to the push-button assembly, causing it to retract relative to the housing, thus protecting the replacement core assembly and extending its service life. Furthermore, the pen-shaped correction tape, in conjunction with the push-button assembly, allows for one-handed operation, making it effortless and convenient. The sliding and extending design replaces the traditional protective cap structure, further extending the service life of the replacement core assembly.

[0011] As an improvement, the push assembly is slidably sleeved with the cover. The push assembly includes a linkage and a pressing button. When the pressing button is subjected to force, it drives the core assembly to slide out through the linkage. A first reset elastic element is installed between the linkage and the cover. In this technical solution, a push-button assembly is slidably sleeved with the cover. The user applies force to the push-button assembly, causing it to slide relative to the cover and drive the replacement core assembly to extend. The push-button assembly includes a linkage and a pressing button. The pressing button serves as the operating part for the user to apply force. The specific structure of the linkage can refer to the push-button structure in existing push-button correction tapes. The locking and unlocking principles of the linkage are the same. When the user presses the pressing button, the pressing button, under the pressure, drives the replacement core assembly to slide out through the linkage. The linkage locks to keep the replacement core assembly in the extended state. A first reset elastic element is installed between the linkage and the cover. The linkage slides under force to compress the first reset elastic element. When the user presses the pressing button again, the pressing button, under the pressure, unlocks the linkage. The linkage and the pressing button automatically reset under the action of the first reset elastic element, causing the replacement core assembly to slide back. The push-button assembly structure is simple and reliable.

[0012] As an improvement, the press button is provided with a second latch, and the cover is provided with a first sliding groove adapted to the first latch. The latch is connected to the first sliding groove to limit the press button to the cover. In this technical solution, by providing a second latch on the press button and a first sliding groove on the cover, and by the second latch being snapped together with the first sliding groove, the press button is limited to the cover and cannot be dislodged from the cover. The second latch and the first sliding groove can slide up and down. When the press button is pressed and slides downward relative to the cover, the second latch slides downward along the first sliding groove. The first sliding groove has a sliding guiding effect on the press button, which is highly efficient and reliable, and makes pressing easier.

[0013] As an improvement, the replacement core assembly is provided with a mounting groove, and the bottom of the linkage component is provided with a mounting seat adapted to the mounting groove, the mounting seat being connected to the mounting groove. In this technical solution, the replacement core assembly is connected to the mounting seat through the mounting groove to cooperate with the linkage component. The linkage component can drive the replacement core assembly to slide up and down within the mounting cavity. The mounting grooves are inserted into each other, making assembly simple and labor-saving.

[0014] As an improvement, the replacement core assembly includes a transfer head, a film belt, a core winding wheel, and a waste belt wheel. The film belt is mounted on the core winding wheel, extends from the core winding wheel, passes around the transfer head, and is then recovered by the waste belt wheel. A guide is installed between the transfer head and the core winding wheel, and the film belt on the core winding wheel is wound around the transfer head via the guide. In this technical solution, the replacement core assembly consists of a transfer head, film belt, core winding wheel, and waste belt wheel. The core winding wheel rotates to release new film belt, which is then covered by the transfer head to the area to be corrected. The waste belt wheel retracts the used film belt. The replacement core assembly has a simple structure. Considering that the installation angle of the transfer head in some replacement core assemblies does not match the angle at which the film belt is pulled out, the film belt needs to be rotated at a certain angle to fit the surface of the transfer head. This solution adds a guide component to the replacement core assembly. The film belt passes through this guide component to the transfer head. Under the action of this guide component, the rotation distance of the film belt can be shortened, and the guide component can maintain the angle at which the film belt is pulled out from the core winding wheel, preventing the film belt rotation from affecting the tape output from the core winding wheel, thereby avoiding tape jamming and improving the user experience.

[0027] like Figures 1 to 7As shown, this application discloses a pen-type coating transfer tool, including a housing 1, a cover 2, and a core assembly 3. The housing 1 and the cover 2 are connected to form a mounting cavity 11 for accommodating the core assembly 3. A connector 4 is installed in the mounting cavity 11. The cover 2 has an extension 21 that enters the mounting cavity 11 and is detachably connected to the connector 4. The connector 4 can lock or unlock the connection between the housing 1 and the cover 2 by connecting or disengaging from the extension 21. The connector 4 has a switch 41. The housing 1 and the cover 2 are connected to form the mounting cavity 11 for mounting the core assembly 3. The connector 4 is provided in the mounting cavity 11, and the extension 21 is provided on the cover 2. When the housing 1 and the cover 2 are connected to form the mounting cavity 11, the extension 21 is located in the mounting cavity 11. The part 21 is detachably connected to the connector 4. The cover 2 is inserted into the mounting cavity 11 through the extension 21. The extension 21 is connected to the connector 4 to lock the connection between the housing 1 and the cover 2. By setting a switch 41 on the connector 4, the switch 41 can be driven to disengage from the extension 21 under force to unlock the connection between the housing 1 and the cover 2. The connector 4 is added between the housing 1 and the cover 2, and the housing 1 and the cover 2 are detachably connected through the connector 4. The replacement core assembly 3 can be replaced after use or damage, which improves the utilization rate and reduces the use cost. Moreover, the connection structure between the connector 4 and the extension 21 is located in the mounting cavity 11 between the housing 1 and the cover 2, which not only has a better appearance, but also has a better overall structural strength, which is conducive to improving the disassembly and assembly stability of the housing 1 and the cover 2.

[0028] The housing 1 is provided with a first opening 12 adapted to the switch 41. The switch 41 protrudes through the first opening 12 for unlocking operation. Considering that the connector 4 is located in the mounting cavity 11, by providing the first opening 12 on the housing 1, the switch 41 protrudes from the first opening 12 in the mounting cavity 11, so that the user can press the switch 41 to apply force for unlocking operation. On the other hand, the first opening 12 cooperates with the switch 41 to limit the connector 4 in the housing 1, which can prevent the connector 4 from shifting and make the use more reliable. In actual use, the user only needs to press the switch 41 to remove the cover 2 from the housing 1, and only needs to insert the extension 21 of the cover 2 into the housing 1 to limit the cover 2 in the housing 1. The structure is simple and reliable, and the disassembly and assembly operation is labor-saving.

[0029] More specifically, such as Figures 2 to 5As shown, the connector 4 is provided with a first latch 42, and the extension 21 is provided with a first latch 211 adapted to the first latch 42. The first latch 42 is connected to the first latch 211 to lock the housing 1 and the cover 2. When the first latch 42 is subjected to force, it disengages from the first latch 211 to unlock the connection between the housing 1 and the cover 2. By providing a first latch 42 on the connector 4 and a first latch 211 on the extension 21, the extension 21 is connected or disengaged from the connector 4 by the cooperation of the first latch 42 and the first latch 211. The locking structure is simple and reliable.

[0030] More specifically, such as Figure 5 As shown, the first latch 42 is a spring-loaded structure mounted on the connector 4, and the switch 41 is mounted on the first latch 42. The first latch 42 is a spring-loaded structure, and the first latch 42 can be connected or disengaged from the first latch position 211 through elastic action. The switch 41 is mounted on the first latch 42, and the force applied to the switch 41 can cause the first latch 42 to elastically deform, making the transmission more labor-saving and reliable. On the other hand, the connector 4 is an integral structure with high structural strength. Its installation in the mounting cavity 11 makes the fit with the cover 2 more reliable, and it can further improve the structural strength of the shell 1.

[0031] More specifically, such as Figure 5 As shown, the first latch 42 is T-shaped and the first latch position 211 is T-shaped. The fact that both the first latch 42 and the first latch position 211 are T-shaped makes the fit simple and reliable.

[0032] More specifically, such as Figures 2 to 5 As shown, the first latch 42 is provided with a guide slope 421 that is adapted to the first latch position 211. The first latch 42 is inserted into the first latch position 211 through the guide slope 421. When the connector 4 is inserted into the extension 21, the first latch 42 is elastically deformed under force to connect with the first latch position 211. By providing the guide slope 421 on the first latch 42, the first latch 42 can enter the first latch position 211 more smoothly under the guidance of the guide slope 421, making disassembly and assembly easier.

[0033] More specifically, such as Figure 2As shown, the replacement insert assembly 3 is slidably installed in the mounting cavity 11. The replacement insert assembly 3 is connected to the push-button assembly 5. The push-button assembly 5 is driven by force to slide and extend / retract the replacement insert assembly 3. By setting a slidable replacement insert assembly 3, the replacement insert assembly 3 can slide and extend / retract relative to the housing 1. The replacement insert assembly 3 is connected to the push-button assembly 5. When needed, the user applies force to the push-button assembly 5, and the push-button assembly 5 is driven by force to extend the replacement insert assembly 3 relative to the housing 1. When needed, the user applies force to the push-button assembly 5 again, and the push-button assembly 5 is driven by force to retract the replacement insert assembly 3 relative to the housing 1, thereby protecting the replacement insert assembly 3 and extending its service life. In addition, by setting a pen-shaped correction tape to cooperate with the push-button assembly 5, the user can operate with one hand, which is labor-saving and convenient. The sliding and telescopic setting replaces the traditional protective cap structure, thus extending the service life of the replacement insert assembly 3.

[0034] More specifically, such as Figures 2 to 4 As shown, the push-button assembly 5 is slidably sleeved with the cover 2. The push-button assembly 5 includes a linkage 51 and a pressing button 52. The pressing button 52, when subjected to force, drives the replacement core assembly 3 to slide out through the linkage 51. A first reset elastic element 53 is installed between the linkage 51 and the cover 2. The push-button assembly 5 is slidably sleeved with the cover 2. The user applies force to the push-button assembly 5, causing it to slide relative to the cover 2, thereby driving the replacement core assembly 3 to extend. The push-button assembly 5 includes a linkage 51 and a pressing button 52. The pressing button 52 serves as an operating part for the user to apply force. The specific structure of the linkage 51 can refer to the push-button structure in existing push-button correction tapes. The locking and unlocking principles of the linkage 51 are the same. Specifically, it can adopt a design similar to that of Chinese Utility Model Patent (Patent No.: C). The push-button component 5 in N219505746U or patent number: CN219505748U is not described in detail here. When the user presses the push-button 52, the push-button 52 is subjected to pressure, which drives the core assembly 3 to slide out through the linkage 51. The linkage 51 is locked to keep the core assembly 3 in the extended state. A first reset elastic element 53 is installed between the linkage 51 and the cover 2. The linkage 51 is subjected to force to slide and compress the first reset elastic element 53. When the user presses the push-button 52 again, the push-button 52 is subjected to pressure, which unlocks the linkage 51. The linkage 51 and the push-button 52 are automatically reset under the action of the first reset elastic element 53, so that the core assembly 3 slides back. The push-button component 5 has a simple and reliable structure.

[0035] More specifically, such as Figures 2 to 4As shown, the press button 52 is provided with a second latch 521, and the cover 2 is provided with a first sliding groove 22 that is adapted to the first latch 42. The latch is connected to the first sliding groove 22 so that the press button 52 is limited to the cover 2. By providing the second latch 521 on the press button 52 and the first sliding groove 22 on the cover 2, the press button 52 is limited to the cover 2 by the second latch 521 being snapped into the first sliding groove 22. The press button 52 cannot be detached from the cover 2. The second latch 521 and the first sliding groove 22 can slide up and down. When the press button 52 is pressed and slides downward relative to the cover 2, the second latch 521 slides downward along the first sliding groove 22. The first sliding groove 22 has a sliding guiding effect on the press button 52, which is efficient and reliable, and makes pressing easier.

[0036] More specifically, such as Figure 2 , Figure 6 and Figure 7 As shown, the end of the replacement core assembly 3 is provided with a mounting groove 31, and the bottom of the linkage 51 is provided with a mounting seat 511 that is adapted to the mounting groove 31. The mounting seat 511 is connected to the mounting groove 31. The replacement core assembly 3 is connected to the mounting seat 511 through the mounting groove 31 to cooperate with the linkage 51. The linkage 51 can drive the replacement core assembly 3 to slide up and down in the mounting cavity 11. The mounting grooves 31 are inserted into each other, making assembly simple and labor-saving.

[0037] More specifically, such as Figure 6 and Figure 7 As shown, the replacement core assembly 3 includes a transfer head 32, a film belt 33, a core winding wheel 34, and a waste belt wheel 35. The film belt 33 is mounted on the core winding wheel 34. The film belt 33 extends from the core winding wheel 34, passes around the transfer head 32, and is then collected by the waste belt wheel 35. A guide 36 is installed between the transfer head 32 and the core winding wheel 34. The film belt 33 on the core winding wheel 34 passes through the guide 36 to the transfer head 32 and is wound around it. The replacement core assembly 3 consists of a transfer head 32, a film belt 33, a core winding wheel 34, and a waste belt wheel 35. The core winding wheel 34 rotates to release a new film belt 33. The film belt 33 covers the area to be corrected through the transfer head 32. The waste belt wheel 35 collects the used film belt 33. The replacement core assembly 3 has a simple structure. Considering that the installation angle of the transfer head 32 in some core-replacement assemblies 3 is not compatible with the angle at which the film belt 33 is pulled out, the film belt 33 needs to be rotated at a certain angle to fit against the surface of the transfer head 32. In this solution, a guide 36 is added inside the core-replacement assembly 3. The film belt 33 is wound around the transfer head 32 via the guide 36. Under the action of the guide 36, the rotation distance of the film belt 33 can be shortened, and the guide 36 can maintain the angle at which the film belt 33 is pulled out from the core roller 34, avoiding the rotation of the film belt 33 from affecting the tape output of the core roller 34, thereby avoiding tape jamming and improving the user experience. More specifically, the guide 36 has a cylindrical structure, which makes it more compatible with the film belt 33.

[0038] This application is not limited to the above-described preferred embodiments. Anyone can derive other products in various forms under the guidance of this application. However, regardless of any changes made to their shape or structure, any technical solution that is the same as or similar to that of this application falls within the protection scope of this application.
