Description

Technical Field

[0001] This utility model relates to the field of stationery, and more specifically, to a correction band that can protect the head. Background Technology

[0002] Correction tape is a common stationery item used by students. It uses white, opaque ink to cover up mistakes, making it easier for students to correct them.

[0003] Traditional correction tape has a core belt mounted on a feed roller. The core belt is pulled by the gear drive, which causes the take-up roller to roll up and retract the base tape. During this process, the core belt passes over the top and bottom of the tongue. The pressing and moving action of the tongue causes the correction film of the core belt to cover the paper, concealing typos, stains, etc., so that the text can be corrected.

[0004] When correction tape is in use, its pressure head must be exposed. When not in use, to prevent damage or contamination of the exposed correction tape, the pressure head and the tape roll at the pressure head must be protected. This is usually achieved by using a cover to cover the pressure head, or by moving the pressure head and the tape roll at the pressure head into the housing.

[0005] However, using a separate cover to shield the pressure head has the problem that the cover is easy to lose; moving the pressure head and the tape winding at the pressure head into the outer casing makes the structure very complicated.

[0006] In view of the above, this utility model is hereby proposed. Utility Model Content

[0026] See Figures 1 to 6 As shown in the figure, this application embodiment provides a correction band that can protect the head, including a main shell 1 and a protective cover 2.

[0027] The main shell 1 has a cylindrical shell 11 and an extension frame 12. The cylindrical shell 11 has a cylindrical cavity and a sliding groove 111 communicating with the cylindrical cavity. The sliding groove 111 is a closed ring and extends along the length direction of the cylindrical shell 11. The extension frame 12 is at least partially located in the cylindrical cavity. One end of the extension frame 12 is provided with a spout 121, which at least partially extends out of the opening of the cylindrical cavity.

[0028] The protective cover 2 is at least partially located inside the cylindrical cavity. The protective cover 2 is slidably disposed on the cylindrical shell 11. The protective cover 2 is sleeved on the outside of the extension frame 12. The protective cover 2 has an operating part 21 that extends to the slide groove 111, which restricts the protective cover 2 from detaching from the main shell 1.

[0029] The protective cover 2 has an extended state and a retracted state. In the extended state, the operating part 21 moves to one end of the slide groove 111, the protective cover 2 extends out of the cylindrical cavity, and the nozzle 121 is located inside the protective cover 2. In the retracted state, the operating part 21 moves to the other end of the slide groove 111, the protective cover 2 is at least partially retracted into the cylindrical cavity, and the nozzle 121 is exposed between the protective cover 2 and the cylindrical shell 11.

[0030] The correction tape provided in this application, which protects the head, is equipped with a protective cover 2. When the protective cover 2 is in the retracted state, the tape nozzle 121 is exposed for correction purposes. When the protective cover 2 is in the extended state, it covers the tape nozzle 121, protecting both the nozzle 121 and the correction tape from damage, as well as preventing damage or contamination of the correction tape. Furthermore, the operating part 21 of the protective cover 2 is embedded in a groove 111 on the cylindrical shell 11. The groove 111 is a closed annular groove that limits the operating part 21, ensuring that the protective cover 2 does not excessively slide off the cylindrical shell 11 when switching states. A simple and easily manufactured structure achieves good performance.

[0031] In some possible implementations, the protective cover 2 includes a cylindrical body 22 and two elastic plates 23. The two elastic plates 23 are disposed on opposite sides of the cylindrical body 22 and are connected to the cylindrical body 22. The elastic plates 23 are located within the cylindrical cavity and abut against the inner wall of the cavity. In the extended state, the elastic plates 23 are located within the cylindrical cavity, the cylindrical body 22 extends out of the shell 11, and covers the nozzle 121.

[0032] The outer periphery of the cylinder 22 is fully enclosed, providing comprehensive protection for the nozzle 121 when extended. When the protective cover 2 is not inserted into the cylinder shell 11, the distance between the outermost edges of the two elastic plates 23 on the side opposite to the cylinder 22 is greater than the diameter of the cylinder shell 11. When the protective cover 2 is inserted into the cylinder shell 11, it is an interference fit, ensuring a stable connection. More importantly, it allows the protective cover 2 to remain relatively stable with the cylinder shell 11 without significant external force applied to the operating part 21, enabling it to stably remain in either the extended or retracted state. However, applying a certain external force to the operating part 21 can switch the protective cover 2's state.

[0033] In some possible implementations, the extension length of the elastic sheet 23 is greater than the extension length of the cylinder 22. Increasing the extension length of the elastic sheet 23 can effectively increase the elastic force of the elastic sheet 23 and effectively improve the friction between the elastic sheet 23 and the inner wall of the cylinder 11.

[0034] In some possible implementations, the operating part 21 is located at the middle of the elastic plate 23 along its length. This arrangement allows the elastic plate 23 to be moved away from the inner wall of the cylinder shell 11 when the operating part 21 is pressed, reducing or eliminating the friction between the elastic plate 23 and the cylinder shell 11 on that side, making the state switching process easier. After the state switch is complete, releasing the pressure on the operating part 21 causes the elastic plate 23 to spring back and press against the inner wall of the cylinder shell 11, thus maintaining the current state in a stable manner.

[0035] In some possible implementations, the cross-section of the elastic sheet 23 is arc-shaped. The arc shape can better fit the inner wall of the cylindrical shell 11, increase the contact area between the elastic sheet 23 and the inner wall of the cylindrical shell 11, effectively increase the friction between the elastic sheet 23 and the cylindrical shell 11, and ensure that the protective cover 2 can be stably in the extended or retracted state.

[0036] In some possible implementations, a deformation notch 24 is formed between the two elastic plates 23. When the protective cover 2 is not inserted into the cylindrical shell 11, the width of the deformation notch 24 gradually increases in the direction from the cylindrical body 22 to the elastic plate. This ensures that the distance between the outermost edges of the two elastic plates 23 connected to the cylindrical body 22 is less than the diameter of the cylindrical shell 11, allowing the cylindrical body 22 to smoothly enter and exit the cylindrical shell 11. When the protective cover 2 is not installed in the cylindrical shell 11, and the elastic plates 23 are in their natural state, the distance between the outermost edges of the two elastic plates 23 on the side away from the cylindrical body 22 is greater than the diameter of the cylindrical shell 11. When the protective cover 2 is inserted into the cylindrical shell 11, the two elastic plates 23 are pressed against each other, making the distance between the outermost edges of the elastic plates 23 on the side away from the cylindrical body 22 less than the inner diameter of the cylindrical shell 11, allowing for smooth insertion into the cylindrical shell 11. When the protective cover 2 is not inserted into the cylindrical shell 11, the elastic plates 23 elastically abut against the inner wall of the cylindrical shell 11. The thermoplastic material consists of two elastic sheets 23, which have a simple structure, simple production process, and good performance.

[0037] In some possible implementations, the extension frame 12 includes a wide section 122 and a narrow section 123, the narrow section 123 being connected to the wide section 122, and the spout 121 being connected to the end of the narrow section 123 opposite to the wide section 122. The deformation notch 24 has a communicating wide notch 241 and a narrow notch 242, which are sequentially arranged in the direction from the cylinder 22 to the elastic sheet. In the retracted state, the wide section 122 is located inside the wide notch 241, and the narrow section 123 is located on one side of the narrow notch 242. The narrow section 123 provides greater deformation space for the two elastic sheets 23, allowing the protective cover 2 to retract as much as possible when switching states or being installed into the cylinder 11, making both switching states and installation into the cylinder 11 less strenuous. The wide section 122 can increase the overall length of the extension frame 12 and has a positioning effect, ensuring the relative position between the extension frame 12 and the protective cover 2 is stable, and further ensuring that the protective cover 2 will not slide excessively or rotate relative to each other.

[0038] In some possible implementations, limiting portions 112 are respectively provided at both ends of the slide 111 along its length, and limiting engagement portions 211 are provided on the operating portion 21. In the extended or retracted state, the limiting portions 112 and the limiting engagement portions 211 engage in a limiting fit. This engagement further ensures the stability of the protective cover 2 in both the extended and retracted states, preventing accidental switching of states inside the pencil case.

[0039] In some possible implementations, the limiting part 112 includes a protrusion disposed on the inner wall of the slide groove 111, and the limiting mating part 211 includes a groove disposed on the side wall of the operating part 21. In the extended or retracted state, the protrusion is embedded in the groove. The protrusion and the groove form a locking engagement; a small force cannot release the engagement between the protrusion and the groove, and a larger force is required to release the engagement between the protrusion and the groove.

[0040] In some possible implementations, the correction tape that protects the head includes a tape reel 3 and a tape release 4. The tape reel 3 and tape release 4 are located on opposite sides of the extension frame 12 and are connected to each other, capable of rotating synchronously. The tape wraps around the tape nozzle 121, with both ends wound around the tape reel 3 and tape release 4 respectively. The structure and arrangement of the tape reel 3 and tape release 4 are existing mature technologies for correction tapes and will not be described in detail here.

[0041] It should be noted that the cross-section of the protective cover and the main shell in this application can be circular, polygonal or other shapes. This application does not limit the specific shape of the protective cover and the main shell, and any shape of the protective cover and the main shell is within the protection scope of this application.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
