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 device is a tool used to transfer coatings from a transfer belt to a target surface, such as transferring a correction coating onto paper. It is widely used in offices, schools, and decoration. A coating transfer device typically consists of a housing, a transfer belt, a transfer head, and a power mechanism. In use, pressing the transfer head causes the coating on the transfer belt to contact and adhere to the surface to be transferred, thus achieving coating transfer. However, the housing of traditional coating transfer devices is not removable, meaning that once the transfer belt is used up, the entire device becomes unusable and must be discarded. This limits the reusability of the product, increases operating costs, and also wastes resources and burdens the environment.

[0003] To address the aforementioned issues, Chinese utility model patent CN215921718U discloses a push-button pen-type correction tape, comprising a nozzle, an outer shell, an inner shell, a take-up roller, a feed roller, a spring, and a push-button mechanism. The nozzle is connected to the front end of the inner shell. The take-up roller and the feed roller are meshed and fixedly disposed within the inner shell. The front end of the inner shell abuts against the front end of the inner shell via the spring. The inner shell is movably connected to the push-button mechanism, allowing the nozzle to extend movably out of the first opening of the outer shell. The outer shell comprises a front shell and a rear shell. The left and right sides of the front shell are respectively provided with connecting slots. The rear shell has two corresponding sides on which it connects to the front shell, and the connecting slots of the rear shell engage with the connecting slots of the front shell. In this technical solution, the front and rear shells are connected by snap-fitting protrusions and connecting slots, which solves the problem that the traditional correction tape shell cannot be disassembled. However, the shell is composed of a front shell and a rear shell. The split design is prone to loosening or separation during use, especially when used frequently or subjected to external impact, which may affect the normal use of the correction tape. The split shell has poorer integrity than the one-piece shell, and there are still many problems in actual use. Summary of the Invention

[0004] The technical problem to be solved by this application is to provide a coating transfer tool with a design in which the first housing and the second housing are connected by a snap-fit, making the two housings more stable during use, improving the structural strength of the entire housing, solving the problem of poor integrity of traditional split housings, and improving the overall performance of the product.

[0005] This application provides a coating transfer tool, including a first housing and a second housing. The first housing is provided with an elastic buckle, and the second housing is provided with a fastening position adapted to the elastic buckle. The second housing is provided with a first opening for the first housing to pass through. The first housing passes through the first opening and is inserted into the second housing. The first housing and the second housing are inner and outer sleeved together. The elastic buckle is connected to the fastening position to lock the connection between the first housing and the second housing. The fastening position is provided with a pressing structure. The pressing structure is connected to the elastic buckle. When the pressing structure is subjected to pressing force, the pressing structure pushes the elastic buckle to disengage from the fastening position, thereby unlocking the connection between the first housing and the second housing.

[0006] In this technical solution, the first and second housings are connected by elastic snap-fit ​​fasteners. Utilizing the elasticity of the material, the two housings can be quickly locked and unlocked without additional fasteners. This not only ensures the connection stability of the first and second housings but also facilitates disassembly and replacement by the user. The design of the first and second housings using an inner and outer sleeve joint allows for a tight fit during assembly, making them more stable during use. Furthermore, the first housing is concealed within the second housing, increasing the overall structural strength and reducing loosening caused by external impacts or vibrations. The second housing has a first opening for the first housing to pass through, simplifying the assembly process, improving assembly efficiency, and further enhancing the connection stability and strength between the first and second housings. The elastic snap-fit ​​is designed into the second housing... Internally, protected by the second housing, the elastic buckle is less susceptible to direct impact or wear during use, reducing the risk of deformation or damage due to external forces and extending its service life. The integrated buckle design of the first and second housings solves the problem of poor overall integrity in traditional split housings, improving the overall performance of the product. A pressing structure is added for unlocking the elastic buckle. Users can easily push the buckle away from the latch by applying force to the pressing structure, eliminating the need to press through the latch and avoiding unlocking difficulties caused by fingers not being able to reach the latch. The pressing structure transmits force to the elastic buckle through mechanical transmission, reducing the force required for direct pressing and making unlocking easier and less strenuous. Furthermore, the pressing structure is housed within the latch, minimizing its impact on the overall structure and dimensions of the second housing, resulting in better overall integrity.

[0007] As an improvement, the length of the engagement portion between the elastic buckle and the latch is less than the width of the latch. This technical solution addresses the issue that in traditional designs, the elastic buckle is fully engaged with the latch, allowing it to protrude through the latch for direct user pressing to unlock. This requires a significant pressing length, necessitating deeper pressure to disengage the buckle and complete the unlocking process. This not only increases the difficulty of unlocking but may also cause inconvenience. By adding a pressing structure designed to be housed within the latch, the length of the engagement portion between the elastic buckle and the latch is less than the width of the latch. Therefore, the length of the engagement portion is effectively reduced, meaning that unlocking... During the locking process, the force and pressing stroke required for unlocking are effectively reduced, and the resistance that the elastic buckle needs to overcome is reduced, thereby achieving the purpose of unlocking with less effort. It should be noted that the length of the joint portion in this application refers to the projected length of the joint portion of the elastic buckle and the buckle in the width direction. The joint portion is not only the part where the elastic buckle and the buckle are physically in contact with each other, but also more broadly covers the part of the two parts that actually play a locking role in the joint state. The contact between the two parts can be point contact, line contact or surface contact, and the joint portion described in this application is applicable to all of them. Even if the joint surface is an inclined surface, this definition still applies.

[0008] As an improvement, the pressing structure is a first elastic arm disposed within the latch. One end of the first elastic arm is connected to the latch, and the other end is used to connect to the elastic buckle. In this technical solution, the pressing structure adopts the form of a first elastic arm, utilizing elastic deformation capability to achieve unlocking and resetting functions. The design of one end of the first elastic arm being fixedly connected within the latch and the other end being used to connect to the elastic buckle ensures effective force transmission during pressing. The user only needs to press the other end of the first elastic arm to push the elastic buckle away from the latch, thus achieving the unlocking function. The design of the first elastic arm utilizes the elasticity of the material, maintaining good performance during repeated pressing and releasing, and making the entire unlocking mechanism more compact.

[0009] As an improvement, the elastic buckle is a second elastic arm disposed on the first housing. One end of the second elastic arm is connected to the first housing, and the other end is used to connect to the buckle position. In this technical solution, the elastic buckle adopts the form of a second elastic arm, utilizing the elastic deformation capability to achieve locking, unlocking, and resetting functions. One end of the second elastic arm is fixedly connected to the first housing, and the other end is used to connect to the buckle position, ensuring that force can be effectively transmitted when pressed. By applying force to the elastic buckle, it is disengaged from the buckle position, thus achieving the unlocking function. The design of the second elastic arm utilizes the elasticity of the material, maintaining good performance during repeated pressing and releasing.

[0010] As an improvement, the other end of the second elastic arm is provided with a protruding structure, through which the second elastic arm connects to or disengages from the latch. In this technical solution, the protruding structure at the other end of the second elastic arm provides a clear contact point and action point when connecting and disengaging from the latch, making the connection between the first and second housings more stable and reducing loosening or separation caused by external forces. The protruding structure and the latch connection can firmly lock the first and second housings, and disengaging the protruding structure and the latch can unlock the first and second housings. The second elastic arm has good elasticity, capable of sufficient deformation when pressed and returning to its original shape after release, ensuring that the protruding structure can accurately engage with the latch, making the locking more reliable.

[0011] As an improvement, the protruding structure is provided with a first guide ramp, through which the protruding structure passes through the first opening and is inserted into the second housing. In this technical solution, the protruding structure is provided with a first guide ramp, which guides the protruding structure as it passes through the first opening and is inserted into the second housing, allowing the protruding structure to enter the locking position more smoothly. This reduces potential jamming or misalignment problems during assembly, improving assembly reliability and efficiency. The first guide ramp guides the protruding structure to accurately enter the locking position during insertion, ensuring the stability and reliability of the connection. The design of the first guide ramp reduces the impact and wear on the protruding structure during insertion, increasing its service life.

[0012] As an improvement, the inner wall of the first housing is provided with a second guide slope adapted to the protruding structure. The protruding structure passes through the first opening along the second guide slope and is inserted into the second housing. In this technical solution, the second guide slope on the inner wall of the first housing guides the protruding structure as it passes through the first opening and is inserted into the second housing, allowing the protruding structure to enter the locking position more smoothly and reducing potential jamming or misalignment problems during assembly. The design of the second guide slope enables the first housing to be inserted into the second housing more smoothly, improving assembly reliability and efficiency. Furthermore, the design of the second guide slope reduces the impact and wear on the protruding structure during insertion, extending its service life.

[0013] As an improvement, the first housing is provided with a limiting seat adapted to the first opening. The first housing is positioned on the second housing by the limiting seat abutting against the first opening vertically. In this technical solution, a limiting seat is provided on the first housing, and the limiting seat abuts against the first opening of the second housing vertically, thereby limiting the first housing to the second housing. The limiting seat can precisely control the relative position of the first housing and the second housing, ensuring that they can be accurately positioned and stably connected during assembly. The limiting seat is designed to match the edge of the first opening, so that the first housing can be precisely limited when inserted into the second housing, avoiding the first housing being over-inserted into the second housing and causing assembly errors, thus improving the accuracy and reliability of assembly. Guided by the limiting seat, the first housing can be accurately inserted into the predetermined position, improving assembly efficiency.

[0014] As an improvement, a replacement core assembly is installed inside the second housing. The second housing has a second opening that adapts to the head of the replacement core assembly, and the head of the replacement core assembly extends through the second opening. In this technical solution, the first and second housings are detachably connected, and the replacement core assembly is installed inside the second housing. This allows the replacement core assembly to be easily inserted or replaced, improving the maintainability and service life of the product. When the replacement core assembly is exhausted or damaged, the user can easily replace it without replacing the entire device, reducing operating costs. A first opening is provided at one end of the second housing, and a second opening is provided at the other end, allowing the replacement core assembly to be installed into the second housing along its length, making assembly simpler and more efficient.

[0015] As an improvement, the replacement core assembly is slidably installed within the second housing. A button and a drive assembly are mounted on the first housing. One side of the drive assembly is connected to the button, and the other side is connected to the replacement core assembly. Force applied to the button drives the replacement core assembly to slide and extend / retract via the drive assembly. In this technical solution, the replacement core assembly is slidable within the second housing, enabling its extension / retraction function. A button and drive assembly are added to the first housing. Pressing the button transmits force to the replacement core assembly, achieving its sliding extension / retraction. In use, the head of the replacement core assembly extends through a second opening for user access. In storage, the head retracts through the second opening to be completely stored within the second housing. The sliding extension / retraction mechanism extends the service life of the replacement core assembly. Attached Figure Description

[0026] like Figures 1 to 5As shown, this application discloses a coating transfer tool, including a first housing 1 and a second housing 2. The first housing 1 is provided with an elastic buckle 11, and the second housing 2 is provided with a fastening position 21 adapted to the elastic buckle 11. The first housing 1 and the second housing 2 are connected by the elastic buckle 11 and the fastening position 21. Utilizing the elasticity of the material, the two housings can be quickly locked and unlocked without the need for additional fasteners. This not only ensures the connection stability of the first housing 1 and the second housing 2, but also facilitates disassembly and replacement by the user. The second housing 2 is provided with a first opening 22 for the first housing 1 to pass through. The first housing 1 passes through the first opening 22 and is inserted into the second housing 2, forming an inner and outer sleeve connection between the first housing 1 and the second housing 2. The elastic buckle 11 connects with the fastening position 21 to lock the connection between the first housing 1 and the second housing 2. When the elastic buckle 11 is subjected to force, it disengages from the fastening position 21 to unlock the connection between the first housing 1 and the second housing 2. The design combines the first housing 1 and the second housing 2 through an inner and outer sleeve connection. Together, they allow for a tight fit between the two housings during assembly, making them more stable during use. The first housing 1 is concealed within the second housing 2, improving the overall structural strength and reducing loosening caused by external impacts or vibrations. The second housing 2 has a first opening 22 for the first housing 1 to pass through, simplifying the assembly process, improving efficiency, and further enhancing the connection stability and strength between the two housings. The elastic buckle 11 is designed inside the second housing 2, protecting it from direct impacts or wear, reducing the risk of deformation or damage and extending its lifespan. The modular buckle connection between the first housing 1 and the second housing 2 solves the problem of poor overall integrity in traditional split housings, improving the overall performance of the product.

[0027] More specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the buckle 21 is provided with a pressing structure 23, which is connected to the elastic buckle 11. When the pressing structure 23 is subjected to pressing force, it pushes the elastic buckle 11 away from the buckle 21, thereby unlocking the connection between the first housing 1 and the second housing 2. By adding the pressing structure 23, which is used for unlocking the elastic buckle 11, the user can easily push the elastic buckle 11 away from the buckle 21 by applying force to the pressing structure 23, without having to press the elastic buckle 11 through the buckle 21. This avoids the difficulty of unlocking caused by the inability of the finger to enter the buckle 21. The pressing structure 23 transmits force to the elastic buckle 11 through mechanical transmission, reducing the force required for the user to press directly, making the unlocking operation easier and less strenuous. Furthermore, the pressing structure 23 is housed within the buckle 21, which has little impact on the overall structure and size of the second housing 2, resulting in better overall integrity of the second housing 2.

[0028] More specifically, such as Figure 5 As shown, the length of the joint between the elastic buckle 11 and the latch 21 is less than the width of the latch 21. Considering that in traditional designs, the elastic buckle 11 and the latch 21 are fully engaged, allowing the elastic buckle 11 to protrude through the latch 21 for the user to directly press the elastic buckle 11 to unlock, the required pressing length is relatively large. The user needs to press deeply to disengage the elastic buckle 11 from the latch 21, which not only increases the difficulty of unlocking but may also cause inconvenience to the user. In this solution, a pressing structure 23 is added. The pressing structure 23 is designed to be housed within the latch 21, and the length of the joint between the elastic buckle 11 and the latch 21 is less than the width of the latch 21. Therefore, the elastic buckle... The length of the engagement portion between the elastic buckle 11 and the latch 21 is effectively reduced, which means that the force and pressing stroke required for unlocking are effectively reduced during the unlocking process, and the resistance that the elastic buckle 11 needs to overcome is reduced, thereby achieving the purpose of unlocking with less effort. It should be noted that the length of the engagement portion in this application refers to the projected length of the engagement portion between the elastic buckle 11 and the latch 21 in the width direction. The engagement portion is not only the part where the elastic buckle 11 and the latch 21 are physically in contact with each other, but also more broadly covers the part where the two parts actually play a locking role in the engagement state. The contact between the two parts can be point contact, line contact or surface contact, and the engagement portion described in this application applies to all of them. Even if the engagement surface is an inclined surface, this definition still applies.

[0029] More specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the pressing structure 23 is a first elastic arm disposed within the buckle 21. One end of the first elastic arm is connected to the buckle 21, and the other end of the first elastic arm is used to connect to the elastic buckle 11. The pressing structure 23 adopts the form of a first elastic arm, which utilizes the elastic deformation capability to realize the unlocking and resetting functions. The design of one end of the first elastic arm being fixedly connected to the buckle 21 and the other end being used to connect to the elastic buckle 11 ensures that force can be effectively transmitted when pressed. The user only needs to press the other end of the first elastic arm to push the elastic buckle 11 away from the buckle 21 to realize the unlocking function. The design of the first elastic arm utilizes the elasticity of the material, which can maintain good performance during repeated pressing and releasing, and makes the entire unlocking mechanism more compact.

[0030] More specifically, such as Figures 3 to 5 As shown, the elastic buckle 11 is a second elastic arm disposed on the first housing 1. One end of the second elastic arm is connected to the first housing 1, and the other end of the second elastic arm is used to connect to the buckle 21. The elastic buckle 11 adopts the form of a second elastic arm, which utilizes the elastic deformation capability to realize the locking, unlocking and resetting functions. One end of the second elastic arm is fixedly connected to the first housing 1, and the other end is used to connect to the buckle 21, ensuring that force can be effectively transmitted when pressed. By applying force to the elastic buckle 11, it is disengaged from the buckle 21, realizing the unlocking function. The design of the second elastic arm utilizes the elasticity of the material, which can maintain good performance during repeated pressing and releasing.

[0031] More specifically, such as Figures 3 to 5 As shown, the other end of the second elastic arm is provided with a protruding structure 12. The second elastic arm is connected to or disengaged from the latch 21 through the protruding structure 12. The protruding structure 12 at the other end of the second elastic arm provides a clear contact point and action point when connecting and disengaging from the latch 21, making the connection between the first housing 1 and the second housing 2 more stable and reducing the problem of loosening or separation caused by external force. The connection between the protruding structure 12 and the latch 21 can firmly lock the first housing 1 and the second housing 2. The disengagement of the protruding structure 12 and the latch 21 can unlock the first housing 1 and the second housing 2. The second elastic arm has good elasticity and can generate sufficient deformation when pressed and return to its original shape after release, ensuring that the protruding structure 12 can accurately cooperate with the latch 21, making the locking more reliable.

[0032] More specifically, such as Figure 3As shown, the protruding structure 12 is provided with a first guide slope 121. The protruding structure 12 passes through the first opening 22 and is inserted into the second housing 2 through the first guide slope 121. The first guide slope 121 is used to guide the protruding structure 12 when it passes through the first opening 22 and is inserted into the second housing 2, so that the protruding structure 12 can enter the snap-fit ​​21 more smoothly, reducing the possible jamming or misalignment problems during assembly, improving the reliability and efficiency of assembly. The first guide slope 121 can guide the protruding structure 12 to accurately enter the snap-fit ​​21 during the insertion process, ensuring the stability and reliability of the connection. The design of the first guide slope 121 reduces the impact and wear on the protruding structure 12 during the insertion process, and improves the service life of the protruding structure 12.

[0033] More specifically, such as Figure 2 and Figure 5 As shown, the inner wall of the first housing 1 is provided with a second guide slope 24 adapted to the protruding structure 12. The protruding structure 12 passes through the first opening 22 along the second guide slope 24 and is inserted into the second housing 2. The second guide slope 24 is provided on the inner wall of the first housing 1. The second guide slope 24 is used to guide the protruding structure 12 when it passes through the first opening 22 and is inserted into the second housing 2, so that the protruding structure 12 can enter the latch 21 more smoothly, reducing the possible jamming or misalignment problems during assembly. The design of the second guide slope 24 enables the first housing 1 to be inserted into the second housing 2 more smoothly, improving the reliability and efficiency of assembly. The design of the second guide slope 24 reduces the impact and wear on the protruding structure 12 during the insertion process, and improves the service life of the protruding structure 12.

[0034] More specifically, such as Figure 2 , Figure 3 and Figure 5 As shown, the first housing 1 is provided with a limiting seat 13 adapted to the first opening 22. The first housing 1 is limited to the second housing 2 by the limiting seat 13 abutting against the first opening 22 vertically. The limiting seat 13 is provided on the first housing 1, and the first housing 1 is limited to the second housing 2 by the limiting seat 13 abutting against the first opening 22 of the second housing 2 vertically. The limiting seat 13 can precisely control the relative position of the first housing 1 and the second housing 2, ensuring that the two can be accurately positioned and stably connected during assembly. The limiting seat 13 is designed to match the edge of the first opening 22, so that the first housing 1 can be precisely limited when inserted into the second housing 2, avoiding the first housing 1 being over-inserted into the second housing 2 and causing assembly errors, thus improving the accuracy and reliability of assembly. With the guidance of the limiting seat 13, the first housing 1 can be accurately inserted into the predetermined position, improving assembly efficiency.

[0035] More specifically, such as Figure 2 and Figure 4 As shown, a replacement core assembly 3 is installed inside the second housing 2. The second housing 2 has a second opening 25 that matches the head of the replacement core assembly 3. The head of the replacement core assembly 3 extends through the second opening 25. The first housing 1 and the second housing 2 are detachably connected. The replacement core assembly 3 is installed inside the second housing 2, which makes it easy to insert or replace the replacement core assembly 3, improving the maintainability and service life of the product. When the replacement core assembly 3 is used up or damaged, the user can easily replace it without replacing the entire device, reducing the cost of use. A first opening 22 is provided at one end of the second housing 2, and a second opening 25 is provided at the other end of the second housing 2, so that the replacement core assembly 3 can be installed into the second housing 2 along the length direction of the second housing 2, making the assembly simpler and more efficient.

[0036] More specifically, such as Figure 2 and Figure 4 As shown, the replacement core assembly 3 is slidably installed inside the second housing 2. A button 4 and a drive assembly 5 are installed on the first housing 1. One side of the drive assembly 5 is connected to the button 4, and the other side of the drive assembly 5 is connected to the replacement core assembly 3. When the button 4 is subjected to force, the drive assembly 5 drives the replacement core assembly 3 to slide and extend. The replacement core assembly 3 is set to slide within the second housing 2. The replacement core assembly 3 can achieve the extension and retraction function by sliding. The button 4 and the drive assembly 5 are added to the first housing 1. When the button 4 is pressed, the drive assembly 5 transmits force to the replacement core assembly 3 to realize the sliding extension and retraction of the replacement core assembly 3. In the use state, the head of the replacement core assembly 3 extends out through the second opening 25 for user use. In the storage state, the head of the replacement core assembly 3 retracts through the second opening 25 to be completely stored in the second housing 2. The replacement core assembly 3 extends its service life by sliding and extending.
