Description

Technical Field

[0001] The present application relates to the technical field of transfer tools, and more specifically to a coating film transfer tool. Background Art

[0002] A coating transfer tool is a tool that can transfer the coating on a coating tape to the surface of other objects, such as correction tape. Existing coating transfer tools generally include a shell, a transfer head and a refill assembly. The refill assembly is equipped with a film tape for transfer, and the coating on the film tape is transferred to the surface of other objects through the transfer head. When using a correction tape, for example, the transfer head is pressed down on the paper surface and then moved sideways with appropriate force, so that the coating on the film tape can be transferred to the paper surface to achieve a correction effect. The portion of the film tape wrapped around the transfer head is exposed to the outside of the shell together with the transfer head, which can easily cause the film tape and the transfer head to become dirty or damaged when stored. Therefore, most of them are currently provided with a protective cap that matches the transfer head. When storing, the user needs to cover the protective cap on the transfer head for protection, and the protective cap needs to be removed when in use. In actual use, the opening and closing operations need to be repeated, and the protective cap is easy to lose after being removed, which still has the problem of inconvenience in use. Therefore, in view of the above problems, a technical solution has been proposed to provide a retractable correction tape, such as the utility model patent with publication number: CN217863488U, which discloses a retractable correction tape, including a shell, a retractable assembly, a tape head and a slider, wherein the shell is provided with an opening; the retractable assembly is movably arranged on the shell; the tape head is arranged at one end of the retractable assembly and can move synchronously with the retractable assembly; the slider is transmission-connected with the retractable assembly; wherein, when the slider moves in a direction away from the opening, the retractable assembly moves in a direction toward the opening, and drives at least a portion of the tape head to extend out of the shell from the opening; when the slider moves in a direction toward the opening, the retractable assembly moves in a direction away from the opening, and drives at least a portion of the tape head to enter the shell from the opening; in this technical solution, through the arrangement of the slider and the retractable assembly, the tape head can be driven by the slider to extend out of or away from the opening of the shell, so that the tape head can be extended when in use and can be retracted when not in use, thereby protecting the tape head. However, the shell opening in this solution is directly connected to the outside, and the whole is in an open state, so that dust, debris, etc. can easily enter the shell from the opening, and the tape core is also easily dried when it is directly in contact with the air, thereby losing its viscosity and affecting its use.

[0042] When it is needed to be used, the switch 3 rotates inwardly under the action of the pressing force, and the switch 3 drives the first transmission gear 41 to rotate through the first arc-shaped rack 31, and the first transmission gear 41 drives the second transmission gear 42 to rotate through the third transmission gear 43, and the second transmission gear 42 drives the core holder 6 to slide through the first linear rack 62, and the core holder 6 drives the core replacement assembly 2 to slide so that the transfer head 21 extends out from the opening 11. When it is needed to be stored, the switch 3 is rotated outwardly and reset by the reset elastic member 32, and the switch 3 drives the first transmission gear 41 to rotate and reset through the first arc-shaped rack 31, and the first transmission gear 41 drives the second transmission gear 42 to rotate and reset through the third transmission gear 43, and the second transmission gear 42 drives the core holder 6 to slide and reset through the first linear rack 62, and the core holder 6 drives the core replacement assembly 2 to slide and reset so that the transfer head 21 retracts from the opening 11. The gear linkage mechanism 4 has a simple and compact structure and efficient transmission.

The first transmission gear 41 is arranged to have a double-layer gear structure consisting of the toothed ring 411 and the second arc-shaped rack 412 distributed up and down, the first transmission gear 41 is meshed with the first arc-shaped rack 31 through the toothed ring 411, and the first transmission gear 41 is meshed with the third transmission gear 43 through the second arc-shaped rack 412, so that the structure of the gear linkage mechanism 4 is more compact, and the double-layer gear structure allows the first transmission gear 41 to be made smaller, which is beneficial to reducing the overall size of the gear linkage mechanism 4 and has higher transmission efficiency.

[0044] More specifically, Figure 6 As shown, the inner wall of one side of the shell 1 is provided with a first mounting column 121, a second mounting column 122, a third mounting column 123 and a fourth mounting column 124, the first mounting column 121 is connected to and limits the first transmission gear 41, the second mounting column 122 is connected to and limits the second transmission gear 42, the third mounting column 123 is connected to and limits the third transmission gear 43, the fourth mounting column 124 is connected to and limits the sealing door 5, the shell 1 is rotatably installed and limits the first transmission gear 41 through the first mounting column 121, that is, the first transmission gear 41 is rotated around the first mounting column 121 under force and is located in the shell 1 through the upper and lower limits of the first mounting column 121, and the shell 1 is connected to the second mounting column 121. 122 is used to rotate, install and limit the second transmission gear 42. The second transmission gear 42 is forced to rotate around the second installation column 122 and is located in the shell 1 through the upper and lower limits of the second installation column 122. The shell 1 rotates and limits the third transmission gear 43 through the third installation column 123. The third transmission gear 43 is forced to rotate around the third installation column 123 and is located in the shell 1 through the upper and lower limits of the third installation column 123. The shell 1 rotates and limits the sealing door 5 through the fourth installation column 124. The sealing door 5 is forced to rotate around the fourth installation column 124 and is located in the shell 1 through the upper and lower limits of the fourth installation column 124. The limiting structure is simple, the rotation is efficient, and the installation is reliable.

[0045] More specifically, Figure 6 As shown, the first mounting column 121, the second mounting column 122, the third mounting column 123 and the fourth mounting column 124 are all arranged on the inner wall of the first shell 12, so that the gear linkage mechanism 4 and the sealing door 5 are both confined in the first shell 12, making the overall assembly simpler and more reliable, and the replacement efficiency of the core assembly 2 is higher.

[0046] More specifically, Figure 3 and Figure 4As shown, the driving structure 61 is arranged on the core replacement seat 6, the driving structure 61 is a convex column, and the sealing door 5 is provided with a guide groove 51 adapted to the driving structure 61, and the driving structure 61 is connected to the guide groove 51. The core replacement seat 6 slides under force through the driving structure 61 and abuts against the inner wall of the guide groove 51 to drive the sealing door 5 to rotate. The driving structure 61 is a convex column arranged on the core replacement seat 6, and the guide groove 51 connecting the convex column is arranged on the core replacement seat 6. When the core replacement seat 6 slides under force, the convex column abuts against the inner wall of the guide groove 51 and pushes the sealing door 5 to rotate along the guide part, so that the core replacement assembly 2 and the sealing door 5 are not easy to get stuck with each other, the transmission efficiency is higher, and the sealing door 5 rotates more smoothly.
