Technical Field
[0001] The utility model relates to the technical field of stationery products, and more specifically to a coating 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. The correction tape generally includes a shell, a correction head and a replacement core assembly. The replacement core assembly is equipped with a film tape for covering the area to be corrected. The film tape bypasses the correction head and covers the area to be corrected through the correction head. In order to prevent the correction head and part of the film tape from being exposed and getting dirty, the correction head and the film tape are currently protected by a protective cap installed on the correction head. However, the correction tape needs to be repeatedly opened and closed during use, which is not only cumbersome to use but also easy to lose the protective cap. Therefore, for example, the utility model patent with publication number: CN219295083U discloses a telescopic film applicator, including an outer shell and a filling body, the outer shell is provided with a sliding member for the filling body to be mounted and combined, the filling body includes a supply reel and a recovery reel for outputting and recovering the film tape, the sliding member can be operated to move forward and backward relative to the outer shell, so that the filling body and a coating head for the film tape to be wound can move forward and backward with the sliding member, and the coating head can extend out of the front opening when moving forward, and retract into the front opening when moving backward. In this scheme, when the user presses the button to push the function key forward, the application head can remain in the forward position and extend out of the front opening to provide the user with application. When the application head is to be retracted after use, the user can press the button again, and the sliding part moves back to the rear position. At the same time, the application head is also retracted to the inside of the front opening and maintained in the outer shell, thereby protecting the application head. However, the opening in this scheme is connected to the outside and is in an open state as a whole. Dust, debris, etc. can easily enter the shell from the opening, and the film belt is directly in contact with the air and is also easy to dry, thereby losing its stickiness. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a coating transfer tool, by arranging a sealing door which can rotate to open and close an opening, the sealing door is linked with the core replacement assembly, when the core replacement assembly is extended, the sealing door is forced to rotate to open the opening, and when the core replacement assembly is retracted, the sealing door rotates and resets to close the opening, thereby protecting the core replacement assembly from external pollution in the shell and extending the service life.
[0004] The utility model provides a coating transfer tool, comprising a shell and a core replacement component, the core replacement component is slidably installed in the shell, the shell is provided with an opening for the core replacement component to slide and retract, a driving member connected to the core replacement component by transmission is installed on the shell, the driving member is subjected to force to drive the core replacement component to slide and retract, the shell is rotatably connected to a sealing door, the sealing door opens and closes the opening by rotating, the core replacement component is provided with a driving part abutting against the sealing door, the sealing door is connected to a first reset elastic part, when the core replacement component slides out, the driving part drives the sealing door to rotate and open the opening by sliding, and when the core replacement component slides back, the sealing door rotates and resets under the action of the first reset elastic part to close the opening.
[0005] In the technical scheme, the user applies force to the driving member, which is transmission-connected with the core replacement assembly. The driving member is subjected to force to drive the core replacement assembly to slide and extend relative to the shell. When in use, the end of the core replacement assembly extends through the opening for user use. When in the storage state, the end of the core replacement assembly retracts through the opening to be completely stored in the shell. The service life of the core replacement assembly is extended by sliding and telescopic means. Considering that the opening is connected to the outside, some dust and debris will still enter the shell through the opening to pollute the core replacement assembly, and the membrane tape on the core replacement assembly is easily dried and loses its viscosity due to excessive contact with the air. In the present scheme, a sealing door is rotatably installed on the shell, and the sealing door can open and close the opening by being rotated under force.

By setting the sealing door connected to the first reset elastic part, the sealing door can be rotated and reset under the action of the first reset elastic part to close the opening. When the user applies force to the driving part, the driving part drives the core replacement assembly to slide out, and the driving part is driven by the force to drive the sealing door to rotate to open the opening, so that the end of the core replacement assembly can extend through the opening. At this time, the first reset elastic part is in a compressed force state. When the user applies force to the driving part again, the driving part is reset by the force and drives the core replacement assembly to slide and retract. The driving part slides and retracts with the core replacement assembly. The sealing door is not subject to the force of the driving part. The sealing door is rotated and reset under the action of the first reset elastic part to close the opening, thereby isolating the core replacement assembly from the outside, protecting the core replacement assembly, slowing down the speed at which the membrane strip becomes dry and ineffective, and extending the service life.
