Description

Technical Field

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

[0002] A coating transfer tool is a tool used to transfer coatings from a transfer belt to a target surface. It is widely used in office supplies, stationery, and various fields requiring surface finishing or covering, with correction tape being one of the most common forms. A coating transfer tool typically consists of a housing, a transfer belt, a transfer head, and a power mechanism. During use, force is applied to the transfer head, causing the coating on the transfer belt to contact and adhere to the surface to be transferred, thus achieving coating transfer. Traditional coating transfer tools have the transfer head directly exposed. When not in use, the transfer head is prone to accumulating dust and impurities, which not only affects the coating transfer effect but may also cause blockage, affecting normal use. Furthermore, the exposed transfer head is easily damaged by accidental contact, reducing the product's lifespan. Currently, the most common method to protect the transfer head and film belt is to attach a protective cap to the transfer head. Some protective caps are connected to the transfer head or housing through a simple snap-fit ​​structure. The protective cap is a separate component. This connection method is prone to causing the protective cap to separate from the main body due to collisions or falling during use, resulting in loss. Furthermore, the protective cap needs to be repeatedly opened and closed during actual use, which is cumbersome.

[0003] To address the aforementioned issues, Chinese utility model patent CN204936614U discloses a spring-pressable pen-type correction tape, comprising a housing, a nozzle, and a tape winding / unwinding device. The housing includes a first housing and a second housing, with a core plate inside. The tape winding / unwinding device and the nozzle are mounted on the core plate. A torsion spring is fixedly mounted on the first housing, with its first arm fixedly connected to the core plate and its second arm extending along the direction away from the protrusion of the core plate. A sliding track is provided on the core plate for the end of the second arm of the torsion spring to slide. A limiting block is provided within the sliding track for the end of the second arm of the torsion spring to be fixedly secured. A button is mounted on the core plate to control the movement of the core plate and to secure the second arm of the torsion spring to or disengage it from the limiting block. A portion of the button extends beyond the second end of the housing. This technical solution employs a press-to-retract design, allowing the user to extend or retract the nozzle (i.e., the aforementioned transfer head) by pressing the button, eliminating the need for a protective cap and solving problems such as the loss of protective caps and short lifespan of transfer heads in traditional coating transfer tools. However, the press-to-retract design lacks a locking mechanism. When carrying or storing the coating transfer tool, the button may be accidentally pressed, causing the transfer head to extend. This increases the risk of the transfer head getting contaminated with dust and impurities and can easily damage the transfer head. During use, the user's finger or other objects may accidentally touch the button, causing the transfer head to retract unexpectedly and affecting normal use. Therefore, users need to be more careful to avoid accidental touches and reduce the user experience. Summary of the Invention

[0004] The technical problem to be solved by this application is to provide a coating transfer tool in which the core assembly can be locked in the non-use state through the cooperation of a locking mechanism and a snap-fit ​​structure, effectively preventing the transfer head of the core assembly from extending or retracting due to accidental contact, thereby improving the safety, durability and user experience of the product.

[0005] This application provides a coating transfer tool, including a housing, a core assembly, and a pressing assembly. The core assembly is slidably installed inside the housing, and the pressing assembly is installed on the housing and connected to the core assembly. The pressing assembly is used to drive the core assembly to slide out or retract. A locking mechanism is installed on the housing, and the core assembly is provided with a snap-fit ​​structure for cooperating with the locking mechanism. The locking mechanism can be switched between a locked position and an unlocked position under force, so that the core assembly can slide to lock or unlock.

[0006] In this technical solution, the housing is the main frame of the entire coating transfer fixture, providing the foundation for the installation and support of other components. The core assembly includes key components such as the coating tape and transfer head required for coating transfer, and is the core part for realizing the coating transfer function. The core assembly can slide within the housing in the telescopic direction, allowing the transfer head to extend out of or retract into the housing. The pressing component is installed on the housing and connected to the core assembly, driving the core assembly to slide out or retract. The pressing component is detachably connected to the housing, facilitating replacement of the core assembly and reducing operating costs. The locking mechanism is installed on the housing, and the core assembly has a snap-fit ​​structure. The snap-fit ​​structure cooperates with the locking mechanism to achieve the locking and unlocking functions of the sliding core assembly. The mechanism can switch between locked and unlocked states by external force (such as pressing, pushing, pulling, etc.). In the locked state, the latching structure interacts with the locking mechanism to restrict the sliding of the refill assembly. In the unlocked state, the latching structure separates from the locking mechanism, allowing the refill assembly to slide under the drive of the pressing component. Through the cooperation of the locking mechanism and the latching structure, the refill assembly can be locked in the non-use state, effectively preventing the transfer head of the refill assembly from extending or retracting due to accidental contact. This avoids exposing key components such as the transfer head to the outside when not in use, reducing the risk of dust and impurities. It also prevents the risk of scratches or other accidental injuries caused by accidental extension, improving the safety, durability, and user experience of the product.

[0007] As an improvement, the locking mechanism includes a push button and an elastic element. The push button is slidably mounted on the housing, and the elastic element is used to elastically engage with the snap-fit ​​structure. The push button is subjected to force to switch between the locked and unlocked positions. When the push button is in the locked position, the push button presses against the elastic element to make the replacement core assembly slide and lock. When the push button is in the unlocked position, the push button releases the elastic element to make the replacement core assembly slide and unlock. In this technical solution, users can control the state of the locking mechanism through a simple sliding operation. The push button switches its position by applying force (such as pressing or flicking with a finger), thereby controlling the working state of the locking mechanism. The operation process is simple and intuitive, and users can easily switch between the locked and unlocked states. When the push button is in the locked position, the push button presses the elastic element, preventing the elastic element from deforming. When the push button is in the unlocked position, the push button releases the elastic element, allowing the elastic element to deform freely. The elastic element interacts with the snap-fit ​​structure on the replacement core assembly. When the elastic element cannot deform, the snap-fit ​​structure cannot pass through the elastic element, and the replacement core assembly is locked. When the elastic element can deform, the snap-fit ​​structure is subjected to force, causing the elastic element to deform and thus pass through the elastic element, allowing the replacement core assembly to slide freely. The design of the locking mechanism is relatively compact and reliable.

[0008] As an improvement, the push button is equipped with a limiting structure adapted to the elastic element. When the push button is in the locked position, the limiting structure presses against the elastic element to lock the replacement core assembly. When the push button is in the unlocked position, the limiting structure releases the elastic element to unlock the replacement core assembly. In this technical solution, the push button is equipped with a limiting structure adapted to the elastic element. The limiting structure can precisely control the state of the elastic element. The elastic element and the limiting structure on the push button are adapted to ensure that the two can cooperate effectively. When the push button is in the locked position, the limiting structure presses against the elastic element, preventing the elastic element from deforming freely and locking the replacement core assembly in the housing to prevent it from sliding. When the push button is in the unlocked position, the limiting structure releases the elastic element, thereby providing sufficient space for the elastic element to deform freely. The elastic element can deform freely, and the snap-fit ​​structure can pass smoothly through the elastic element, allowing the replacement core assembly to slide freely. The adaptation design of the limiting structure and the elastic element can ensure reliable cooperation between the two, improving the stability and reliability of the product.

[0009] As an improvement, the housing is provided with a first mounting groove adapted to the elastic element. The elastic element is installed in the first mounting groove, and the first mounting groove cooperates with the limiting structure to press or release the elastic element. In this technical solution, the housing is provided with a first mounting groove, the shape and size of which are adapted to the elastic element, providing stable support for the elastic element and ensuring that the elastic element will not shift or loosen during use. Furthermore, the cooperative design of the first mounting groove and the limiting structure allows the push button to precisely control the state of the elastic element, ensuring the accuracy of locking and unlocking operations.

[0010] As an improvement, the elastic element is provided with an abutment portion adapted to the snap-fit ​​structure. When the push button is in the locked position, the limiting structure presses the elastic element, causing the abutment portion to abut against the snap-fit ​​structure, and the replacement core assembly slides and locks. When the push button is in the unlocked position, the limiting structure releases the elastic element, allowing the abutment portion to be elastically deformed under force, allowing the snap-fit ​​structure to pass through, and the replacement core assembly slides and unlocks. In this technical solution, the elastic element is provided with an abutment portion, enabling the elastic element to directly contact the snap-fit ​​structure, thereby realizing the locking and unlocking functions. When the push button is in the locked position, the limiting structure presses the elastic element, causing the abutment portion to abut against the snap-fit ​​structure. The snap-fit ​​structure is fixed by the abutment portion, and the replacement core assembly cannot slide, thus achieving locking. When the push button is in the unlocked position, the limiting structure releases the elastic element, allowing the abutment portion to deform freely, and the snap-fit ​​structure to pass smoothly through the abutment portion, allowing the replacement core assembly to slide freely, thus achieving unlocking. The adaptation design of the abutment portion and the snap-fit ​​structure ensures reliable contact between the two, improving the reliability of the product.

[0011] As an improvement, the buckle structure is provided with an arc-shaped guide surface adapted to the abutment part, and the buckle structure cooperates with the abutment part through the arc-shaped guide surface. In this technical solution, the arc-shaped guide surface on the buckle structure makes the contact between the buckle structure and the abutment part smoother and more seamless. The elastic element can deform better through the arc-shaped guide surface in the unlocked state. The design of the arc-shaped guide surface allows the buckle structure to smoothly contact and separate from the abutment part during sliding, reducing friction and wear between the buckle structure and the abutment part. The arc-shaped guide surface plays a guiding role during the unlocking process, ensuring that the buckle structure can smoothly pass through the abutment part, thus improving the smoothness and reliability of the unlocking operation.

[0012] As an improvement, the limiting structure is a protrusion structure set on the inner wall of the push button, and the elastic element is a spring sheet structure. In this technical solution, the limiting structure is designed as a protrusion structure, which can directly press or release the spring sheet to ensure accurate switching between locked and unlocked states and prevent misoperation. The elastic element adopts a spring sheet structure. This design gives the elastic element good elastic deformation ability, which can generate elastic deformation when subjected to force and return to its original shape after the force is removed. The spring sheet structure separates from the limiting structure in the unlocked position. The push button provides enough space to accommodate the spring sheet, allowing the spring sheet to deform freely, thereby avoiding the latching structure and allowing the latching structure to pass smoothly. When the push button is in the locked position, the protrusion structure presses the spring sheet, and the spring sheet abuts against the latching structure. The latching structure is fixed, and the replacement core assembly cannot slide, improving the reliability of the product.

[0013] As an improvement, the housing is provided with a second mounting groove adapted to the push button, and the push button is slidably installed in the second mounting groove. In this technical solution, the second mounting groove provides a precise installation position and sliding track for the push button. The second mounting groove not only fixes the push button, but also guides the sliding movement of the push button, ensuring that the push button can move accurately along a predetermined path. Users can control locking and unlocking through simple sliding operations, making the operation intuitive and easy to master.

[0014] As an improvement, the second mounting groove is provided with a positioning protrusion, and the push button is provided with a first positioning recess and a second positioning recess. The positioning protrusion connects with the first positioning recess to position the push button in the locked position, and the positioning protrusion connects with the second positioning recess to position the push button in the unlocked position. In this technical solution, the positioning recess and the positioning protrusion cooperate to ensure that the push button can be stably held in the corresponding positions when locked and unlocked. When the push button slides to the locked position, the positioning protrusion connects with the first positioning recess on the push button to stably hold the push button in the locked position. When the push button slides to the unlocked position, the positioning protrusion connects with the second positioning recess on the push button to stably hold the push button in the unlocked position. This prevents the push button from shaking or shifting in the locked and unlocked positions, improving the stability of locking and unlocking operations. The cooperation between the positioning recess and the positioning protrusion provides clear feedback, allowing the user to clearly perceive whether the push button has reached the locked or unlocked position, further improving the convenience of operation.

[0015] As an improvement, the push button is provided with an inverted buckle, and the second mounting groove is provided with a sliding groove adapted to the inverted buckle. The inverted buckle connects with the sliding groove, allowing the push button to be slidably installed in the second mounting groove. In this technical solution, the cooperation between the inverted buckle and the sliding groove ensures that the push button can slide stably in the second mounting groove, while preventing the push button from falling out of the mounting groove. The shape and size of the sliding groove are adapted to the inverted buckle, ensuring a reliable fit between the two, allowing the push button to slide smoothly, reducing shaking and offset during the sliding process, and improving the accuracy and reliability of operation.

[0029] like Figures 1 to 8As shown, this application discloses a coating transfer fixture, including a housing 1, a core assembly 2, and a pressing assembly 3. The core assembly 2 is slidably installed inside the housing 1. The housing 1 is the main frame of the entire coating transfer fixture, providing a foundation for the installation and support of other components. The core assembly 2 includes key components such as the coating tape and transfer head 21 required for coating transfer, and is the core part for realizing the coating transfer function. The core assembly 2 can slide in the telescopic direction within the housing 1 to allow the transfer head 21 to extend out of or retract into the housing 1. The pressing assembly 3 is installed on the housing 1 and connected to the core assembly 2. The pressing assembly 3 is used to drive the core assembly 2 to slide out or retract. A locking mechanism 4 is installed on the housing 1, and the core assembly 2 is provided with a snap-fit ​​structure 22 for cooperating with the locking mechanism 4. The locking mechanism 4 can be switched between a locked position and an unlocked position under force to allow the core assembly 2 to slide to lock or unlock. The pressing assembly 3 is installed on the housing 1 and connected to the core assembly 2 to drive the core assembly 2 to slide out or retract. The pressing assembly 3 is detachable from the housing 1. The connection facilitates the replacement of the core assembly 2, reducing usage costs. The locking mechanism 4 is installed on the housing 1. The core assembly 2 is equipped with a snap-fit ​​structure 22. The snap-fit ​​structure 22 cooperates with the locking mechanism 4 to achieve the locking and unlocking functions of the core assembly 2. The locking mechanism 4 can switch between the locked and unlocked states by external force (such as pressing, pushing, pulling, etc.). In the locked state, the snap-fit ​​structure 22 interacts with the locking mechanism 4 to restrict the sliding of the core assembly 2. In the unlocked state, the snap-fit ​​structure 22 separates from the locking mechanism 4, allowing the core assembly 2 to slide under the drive of the pressing component 3. Through the cooperation of the locking mechanism 4 and the snap-fit ​​structure 22, the core assembly 2 can be locked in the non-use state, effectively preventing the transfer head 21 of the core assembly 2 from extending or retracting due to accidental contact. This avoids the key components such as the transfer head 21 from being exposed in the non-use state, reducing the risk of dust and impurities. It also prevents the risk of scratches or other accidental injuries caused by accidental extension, improving the safety, durability, and user experience of the product.

[0030] More specifically, such as Figure 2As shown, the locking mechanism 4 includes a push button 41 and an elastic element 42. The push button 41 is slidably mounted on the housing 1, and the elastic element 42 is used to elastically cooperate with the snap-fit ​​structure 22. The push button 41 switches between the locked and unlocked positions by sliding under force. The user can control the state of the locking mechanism 4 through a simple sliding operation. The push button 41 switches its position by being subjected to force (such as pressing or flicking with a finger), thereby controlling the working state of the locking mechanism 4. The operation process is simple and intuitive, and the user can easily switch between the locked and unlocked states. When the push button 41 is in the locked position, the push button 41... The elastic element 42 is pressed down so that it cannot deform elastically. When the push button 41 is in the unlocked position, the push button 41 releases the elastic element 42, and the elastic element 42 can deform freely. The elastic element 42 interacts with the snap-fit ​​structure 22 on the core assembly 2. When the elastic element 42 cannot deform, the snap-fit ​​structure 22 cannot pass through the elastic element 42, and the core assembly 2 is locked. When the elastic element 42 can deform, the snap-fit ​​structure 22 is forced to deform the elastic element 42, so that it can pass through the elastic element 42, and the core assembly 2 can slide freely. The design of the locking mechanism 4 is relatively compact and reliable.

[0031] More specifically, such as Figure 4 , Figure 6 and Figure 7 As shown, the push button 41 is provided with a limiting structure 411 adapted to the elastic element 42. When the push button 41 is in the locked position, the limiting structure 411 presses the elastic element 42 to make the core assembly 2 slide locked. When the push button 41 is in the unlocked position, the limiting structure 411 releases the elastic element 42 to make the core assembly 2 slide unlocked. The push button 41 is provided with a limiting structure 411 adapted to the elastic element 42. The limiting structure 411 can accurately control the state of the elastic element 42. The elastic element 42 and the limiting structure 411 on the push button 41 are adapted to ensure that the two can cooperate effectively. When the push button 41 is in the locked position, such as Figure 4 As shown, the limiting structure 411 presses the elastic element 42, preventing the elastic element 42 from deforming freely, thus locking the core assembly 2 inside the housing 1 and preventing it from sliding. When the push button 41 is in the unlocked position, as shown... Figure 6 As shown, the limiting structure 411 releases the elastic element 42, thereby providing sufficient space for the elastic element 42 to deform. The elastic element 42 can deform freely, and the snap-fit ​​structure 22 can pass smoothly through the elastic element 42, allowing the core assembly 2 to slide freely. The matching design of the limiting structure 411 and the elastic element 42 can ensure reliable cooperation between the two, improving the stability and reliability of the product.

[0032] More specifically, such as Figure 2 and Figure 8As shown, the housing 1 is provided with a first mounting groove 11 adapted to the elastic member 42. The elastic member 42 is installed in the first mounting groove 11. The first mounting groove 11 cooperates with the limiting structure 411 to press or release the elastic member 42. The housing 1 is provided with a first mounting groove 11. The shape and size of the first mounting groove 11 are adapted to the elastic member 42, providing stable support for the elastic member 42 and ensuring that the elastic member 42 will not shift or loosen during use. Furthermore, the cooperative design of the first mounting groove 11 and the limiting structure 411 enables the push button 41 to accurately control the state of the elastic member 42, ensuring the accuracy of locking and unlocking operations.

[0033] More specifically, such as Figure 4 and Figure 6 As shown, the elastic element 42 is provided with an abutment portion 421 adapted to the buckle structure 22. When the push button 41 is in the locked position, the limiting structure 411 presses the elastic element 42, causing the abutment portion 421 to abut against the buckle structure 22, and the core assembly 2 slides and locks. When the push button 41 is in the unlocked position, the limiting structure 411 releases the elastic element 42, allowing the abutment portion 421 to be elastically deformed under force, allowing the buckle structure 22 to pass through, and the core assembly 2 slides and unlocks. The abutment portion 421 on the elastic element 42 allows the elastic element 42 to directly contact the buckle structure 22, thereby realizing the locking and unlocking functions. When button 41 is in the locked position, the limiting structure 411 presses against the elastic element 42, causing the abutment part 421 to abut against the latching structure 22. The latching structure 22 is fixed by the abutment part 421, and the replacement core assembly 2 cannot slide, thus achieving locking. When button 41 is in the unlocked position, the limiting structure 411 releases the elastic element 42, the abutment part 421 can deform freely, and the latching structure 22 can smoothly pass through the abutment part 421, allowing the replacement core assembly 2 to slide freely, thus achieving unlocking. The matching design of the abutment part 421 and the latching structure 22 ensures reliable contact between the two, improving the reliability of the product.

[0034] More specifically, such as Figure 4 and Figure 6 As shown, the latching structure 22 is provided with an arc-shaped guide surface 221 that is adapted to the abutment part 421. The latching structure 22 cooperates with the abutment part 421 through the arc-shaped guide surface 221. The arc-shaped guide surface 221 on the latching structure 22 makes the contact between the latching structure 22 and the abutment part 421 smoother and more unobstructed. The elastic element 42 can deform better through the arc-shaped guide surface 221 in the unlocked state. The design of the arc-shaped guide surface 221 allows the latching structure 22 to smoothly contact and separate from the abutment part 421 during the sliding process, reducing the friction and wear between the latching structure 22 and the abutment part 421. The arc-shaped guide surface 221 plays a guiding role in the unlocking process, ensuring that the latching structure 22 can pass smoothly through the abutment part 421, thus improving the smoothness and reliability of the unlocking operation.

[0035] More specifically, such as Figure 7 As shown, the limiting structure 411 is a protrusion structure set on the inner wall of the push button 41, and the elastic element 42 is a spring sheet structure. The limiting structure 411 is designed as a protrusion structure, which can directly press or release the spring sheet to ensure accurate switching between locked and unlocked states and prevent misoperation. The elastic element 42 adopts a spring sheet structure. This design gives the elastic element 42 good elastic deformation ability, which can generate elastic deformation when subjected to force and return to its original shape after the force is removed. When the spring sheet structure is in the unlocked position, it is separated from the limiting structure 411. The push button 41 provides enough space to accommodate the spring sheet, allowing the spring sheet to deform freely, thereby avoiding the buckle structure 22 and allowing the buckle structure 22 to pass smoothly. When the push button 41 is in the locked position, the protrusion structure presses the spring sheet, and the spring sheet abuts against the buckle structure 22. The buckle structure 22 is fixed, and the replacement core assembly 2 cannot slide, improving the reliability of the product.

[0036] More specifically, such as Figure 2 and Figure 8 As shown, the housing 1 is provided with a second mounting groove 12 that is adapted to the push button 41. The push button 41 is slidably installed in the second mounting groove 12. The second mounting groove 12 provides a precise installation position and sliding track for the push button 41. The second mounting groove 12 not only fixes the push button 41, but also guides the sliding movement of the push button 41, ensuring that the push button 41 can move accurately along the predetermined path. Users can control locking and unlocking through simple sliding operations. The operation is intuitive and easy to master.

[0037] More specifically, such as Figure 4 , Figure 6 and Figure 8 As shown, the second mounting groove 12 is provided with a positioning protrusion 121, and the push button 41 is provided with a first positioning recess 412 and a second positioning recess 413. The positioning protrusion 121 is connected to the first positioning recess 412 to position the push button 41 in the locked position, and the positioning protrusion 121 is connected to the second positioning recess 413 to position the push button 41 in the unlocked position. The positioning recess and the positioning protrusion 121 cooperate to ensure that the push button 41 can be stably maintained in the corresponding positions when locked and unlocked. When the push button 41 slides to the locked position, the positioning protrusion 121 and the second positioning recess 413 on the push button 41... The first positioning recess 412 connects to keep the push button 41 stably in the locked position. When the push button 41 slides to the unlocked position, the positioning protrusion 121 connects to the second positioning recess 413 on the push button 41, keeping the push button 41 stably in the unlocked position. This prevents the push button 41 from shaking or shifting between the locked and unlocked positions, improving the stability of the locking and unlocking operations. The cooperation between the positioning recess and the positioning protrusion 121 provides clear feedback, allowing the user to clearly perceive whether the push button 41 has reached the locked or unlocked position, further improving the convenience of operation.

[0038] More specifically, such as Figure 2 , Figure 7 and Figure 8 As shown, the push button 41 is provided with a buckle 414, and the second mounting groove 12 is provided with a sliding groove 122 adapted to the buckle 414. The buckle 414 is connected to the sliding groove 122 so that the push button 41 is slidably installed in the second mounting groove 12. The cooperation between the buckle 414 and the sliding groove 122 ensures that the push button 41 can slide stably in the second mounting groove 12, while preventing the push button 41 from coming out of the mounting groove. The shape and size of the sliding groove 122 are adapted to the buckle 414 to ensure a reliable cooperation between the two, so that the push button 41 can slide smoothly, reducing shaking and offset during the sliding process, and improving the accuracy and reliability of operation.

[0039] 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.
