Description

Technical Field

[0001] This utility model relates to the field of stationery technology, specifically to a pen equipped with a protective sleeve. Background Technology

[0002] In daily writing and creative activities, the pen is an indispensable tool, and its grip experience significantly impacts writing quality and efficiency. To improve writing comfort and anti-slip properties, various pen covers have emerged on the market. These covers offer users numerous conveniences. For example, silicone or rubber covers effectively increase friction between the pen and the hand, significantly reducing the risk of the pen slipping during writing and providing a more stable grip. Simultaneously, covers protect the pen body, reducing wear and tear caused by impacts and friction, thus extending the pen's lifespan. Some covers with special patterns or colors also meet users' personalized decoration needs, adding a touch of fun to writing.

[0003] However, existing pen grips typically employ fixed shapes and materials, resulting in significant drawbacks. Their grip cannot be adjusted to suit the user's needs. Different users have different hand sizes, grip habits, and writing durations, making it difficult for grips with a fixed grip to meet diverse usage requirements. For example, for people who write for extended periods, grips with a fixed hardness cannot alleviate hand fatigue. Furthermore, the lack of grip adjustment in current pen grip technology limits the comfort and functionality of pens in actual use. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pen with a protective sleeve, which can adjust the grip of the sleeve to relieve fatigue caused by writing for a long time.

[0005] The technical solution of this utility model is to provide a pen with a protective sleeve having the following structure: a pen barrel, a protective sleeve assembly provided at the lower part of the pen barrel, the protective sleeve assembly including a protective sleeve body and a rotating component, the protective sleeve body being fitted over the rotating component; the rotating component being fitted over the pen barrel; at least one first through hole provided on the side wall of the pen barrel, and at least one second through hole provided on the side wall of the rotating component, wherein rotating the rotating component allows the second through hole to overlap with the first through hole.

[0006] With the above structure, the pen with a protective sleeve of this invention has the following advantages compared with the prior art:

[0007] The protective sleeve assembly of the pen with a protective sleeve of this utility model includes a protective sleeve body and a rotating component. A first through hole is provided on the side wall of the pen barrel, and a second through hole is provided on the side wall of the rotating component. When the rotating component is rotated, the depth of the hollowing will increase when the second through hole overlaps with the first through hole. This will change the grip of the protective sleeve body. Therefore, rotating the rotating component can adjust the grip of the protective sleeve, thereby meeting the different needs of different users for the grip of the protective sleeve, and also relieving fatigue caused by writing for a long time.

[0008] As an improvement, a positioning structure is provided between the rotating component and the pen barrel. This positioning structure includes a positioning protrusion and a positioning groove. The positioning protrusion is located on the rotating component, and the positioning groove is located on the pen barrel; alternatively, the positioning protrusion is located on the pen barrel, and the positioning groove is located on the rotating component. With this structure, when the positioning protrusion is embedded in the positioning groove, the rotating component will not rotate, thus positioning it and preventing rotation during writing.

[0009] As an improvement, the positioning protrusion is located on the side wall of the pen barrel, and the positioning groove is located on the inner wall of the rotating component. There are at least two positioning grooves, and the positioning protrusion is embedded in one of them. By rotating the rotating component, the positioning protrusion can be switched to be embedded in other positioning grooves. This structure is simple and provides good positioning performance.

[0010] As an improvement, a slide rail is provided between adjacent positioning slots. When the rotating component is rotated, the positioning protrusion disengages from the positioning slot, passes through the slide rail, and enters the next positioning slot. When the positioning protrusion enters one of the positioning slots, the first through hole overlaps with the second through hole. With this structure, the sliding rail improves the assembly effect between the rotating component and the pen barrel.

[0011] As an improvement, a spring sheet is provided on the side wall of the pen barrel, and the positioning protrusion is located on the side wall of the spring sheet near the rotating component. With this structure, the positioning protrusion is located on the spring sheet, so that the resistance between the positioning protrusion and the rotating component is small during the rotation of the rotating component, the rotation is more flexible, and the positioning effect of the positioning protrusion is not affected by the elastic force of the spring sheet.

[0012] As an improvement, the pen barrel has a clearance hole on its side wall, and one end of the spring is fixedly connected to the inner wall of the clearance hole. The positioning protrusion protrudes outside the clearance hole and protrudes from the side wall of the pen barrel. With this structure, the spring is simple to set, has better space for deformation, and thus has better elasticity.

[0013] As an improvement, a guide protrusion is provided on the side wall of the spring piece near the rotating component, and a guide groove is provided on the inner wall of the rotating component. The guide protrusion slides within the guide groove. With this structure, the guide protrusion and guide groove guide the rotation of the rotating component, resulting in a better fit between the rotating component and the pen barrel.

[0014] As an improvement, a first limiting protrusion is provided on the side wall of the pen barrel, and a pen tip is provided at the lower end of the pen barrel. The rotating component is axially limited and rotatably mounted between the first limiting protrusion and the pen tip. With this structure, the assembly structure of the rotating component is simple and easy to assemble.

[0015] As an improvement, a second limiting protrusion is provided on the side wall of the rotating component, and the sheath body is axially limited and installed between the second limiting protrusion and the pen tip. With this structure, the assembly structure of the sheath body is simple and easy to assemble.

[0016] As an improvement, the end of the sheath body protrudes beyond the end of the rotating component, and a radial protrusion is provided on the inner wall of the port of the sheath body, which is embedded between the end of the rotating component and the pen tip. This structure improves the fit between the sheath body, the pen barrel, and the rotating component, resulting in greater comfort during use. Attached Figure Description

[0026] like Figures 1 to 5 As shown, this utility model discloses a pen with a protective sleeve, including a pen barrel 1, wherein the lower part of the pen barrel 1 is provided with a protective sleeve assembly.

[0027] The sheath assembly includes a sheath body 2 and a rotating component 3. The rotating component 3 is cylindrical and is fitted onto the lower part of the pen barrel 1. A first limiting protrusion 101 is provided on the side wall of the pen barrel 1, and a pen tip 4 is detachably connected to the lower end of the pen barrel 1. The rotating component 3 is axially limited and rotatably mounted between the first limiting protrusion 101 and the pen tip 4. The rotating component 3 can be detached from the pen barrel 1 by removing the pen tip 4. The structure is simple and easy to assemble.

[0028] The sheath body 2 is also cylindrical and made of a soft material, such as silicone. It is fitted over the rotating component 3. A second limiting protrusion 301 is provided on the side wall of the rotating component 3, and the sheath body 2 is axially positioned between the second limiting protrusion 301 and the pen tip 4. The end of the sheath body 2 protrudes beyond the end of the rotating component 3, and a radial protrusion 201 is provided on the inner wall of the port of the sheath body 2. This radial protrusion 201 is embedded between the end of the rotating component 3 and the pen tip 4. This installation structure makes the sheath body 2 more compact, and the end of the sheath body 2 completely covers the end of the rotating component 3, ensuring comfort for the user during writing.

[0029] The pen barrel 1 has at least one first through hole 102 on its side wall. The first through hole 102 is elongated. In this specific embodiment, there are three first through holes 102, evenly distributed along the circumference of the pen barrel 1. The rotating component 3 has at least one second through hole 302 on its side wall. The second through hole 302 is also elongated. In this specific embodiment, there are three second through holes 302, evenly distributed along the circumference of the rotating component 3. In this specific embodiment, both the first through hole 102 and the second through hole 302 are rectangular. The width of the second through hole 302 is greater than the width of the first through hole 102, and the length of the first through hole 102 is greater than the length of the second through hole 302. When the rotating component 3 is rotated, when it reaches a certain position, the second through hole 302 can overlap with the first through hole 102.

[0030] A positioning structure is provided between the rotating component 3 and the pen barrel 1. The positioning structure includes a positioning protrusion 103 and a positioning groove 303. The positioning protrusion 103 is located on the rotating component 3, and the positioning groove 303 is located on the pen barrel 1; or the positioning protrusion 103 is located on the pen barrel 1, and the positioning groove 303 is located on the rotating component 3. In this specific embodiment, the positioning protrusion 103 is located on the side wall of the pen barrel 1, and the positioning groove 303 is located on the inner wall of the rotating component 3.

[0031] At least two positioning grooves 303 are provided. In this specific embodiment, the positioning protrusions 103 are provided on both sides of the pen barrel 1. Correspondingly, the positioning grooves 303 are also provided on both sides of the inner wall of the rotating member 3, and two positioning grooves 303 are provided on each side. The positioning protrusions 103 are embedded in one of the positioning grooves 303. By rotating the rotating member 3, the positioning protrusions 103 can be switched to be embedded in other positioning grooves 303. In this specific embodiment, when the positioning protrusions 103 are embedded in one of the positioning grooves 303 on one side, the second through hole 302 of the rotating member 3 faces the side wall of the pen barrel 1. When the positioning protrusions 103 are embedded in the other positioning groove 303, the second through hole 302 of the rotating member 3 overlaps with the first through hole 102 on the pen barrel 1, that is, the second through hole 302 is aligned with the first through hole 102.

[0032] The pen barrel 1 has a spring piece 104 on its side wall, and a positioning protrusion 103 is located on the side wall of the spring piece 104 near the rotating member 3. A clearance hole 105 is provided at the location of the spring piece 104 on the side wall of the pen barrel 1. One end of the spring piece 104 is fixedly connected to the inner wall of the clearance hole 105. The positioning protrusion 103 protrudes outside the clearance hole 105 and extends beyond the side wall of the pen barrel 1. The spring piece 104 allows the positioning protrusion 103 to move more flexibly, improving the positioning effect and reducing resistance during the rotation of the rotating member 3, thus enabling easy rotation of the rotating member 3.

[0033] A slide rail 304 is provided between adjacent positioning slots 303. When the rotating component 3 is rotated, the positioning protrusion 103 disengages from the positioning slot 303, passes through the slide rail 304, and enters the next positioning slot 303.

The guide protrusion 106 is slidably engaged in the guide groove 305.

[0034] The pen with a protective sleeve disclosed in this utility model is used by the user holding the upper end of the rotating component 3, namely the second limiting protrusion 301 of the rotating component 3, and then rotating the rotating component 3. The relative position of the rotating component 3 and the pen barrel 1 will change. When rotated to a certain position, the second through hole 302 on the rotating component 3 can overlap with the first through hole 102. At this time, the hollow depth of the inner side of the protective sleeve body 2 is deeper, and the grip will change. At this time, the protective sleeve body 2 is not aligned with the second through hole 302 and the first through hole 102, making it more flexible. During the rotation of the rotating component 3, the protective sleeve body 2 can rotate with it, or it can remain stationary. This is related to the tightness of the fit between the protective sleeve body 2 and the rotating component 3, and can be set as needed.

[0035] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
