Description

Technical Field

[0001] The utility model relates to the field of stationery, in particular to a portable pen sleeve and a pen. Background Art

[0002] A pen is the most basic writing tool for recording language and characters on paper or other materials. Common pens include gel pens, fountain pens, writing brushes, pencils, etc. Pens are used in different occasions in people's work and life. For example, students use pens to take notes and do homework in the classroom, and pens are also used when guests need to sign at the hotel front desk or bank counter. In such occasions, pens are used in fixed places, and it is not easy to have the problem of not being able to find a pen when using it. However, in some other occasions, pens need to be carried around for recording. For example, doctors and nurses need to go to different inpatients for consultations and then record corresponding information during work. In such cases where pens are needed at any time, pens need to be carried around. Existing pens are either equipped with pen clips or not. For pens with pen clips, when carried around, the pen clips are used to clip on the clothes pocket or directly placed in the pocket, while pens without pen clips can only be placed in the pocket. Thus, problems arise in use. Placing pens in the pocket is easy to lose and not convenient for carrying and using. For pens clamped by pen clips, on the one hand, they are not clamped tightly and are easy to fall off and get lost, and on the other hand, there need to be pockets on the clothes or places that can be clamped by the pen clips, so the use has certain limitations and cannot meet the diverse use requirements. Summary of the Utility Model

[0003] Aiming at the existing deficiencies, the utility model provides a portable pen sleeve and a pen.

Detailed implementation mode

[0022] In order to more clearly illustrate the purpose, technical solutions and advantages of the embodiments of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. A clear and complete description is made. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention. In addition, the directional terms mentioned in the present invention, for example, "up", "down", "front", "rear", "left", "right", "inside", "outside", etc., are only references to the directions in the attached drawings. The directional terms used are for better and clearer illustration and understanding of the present invention, rather than indicating or implying the orientation that the present invention must have. Therefore, it cannot be understood as a limitation to the present invention.

[0023] The embodiments of the present invention are as follows Figures 1 to 6As shown in the figure, a portable pen sleeve includes a sleeve body 1 with a cylindrical structure. The cylindrical structure means that there is a through hole running through both ends of the sleeve body 1 inside. The sleeve body 1 is made of rubber or silica gel. If it is made into a cylindrical structure, when in use, the pen is placed inside the sleeve body 1, and the structure on the sleeve body 1 is used to achieve portability. One situation of the pen inside the sleeve body 1 is that the tip part of the pen protrudes from the lower end of the sleeve body 1, and the pen does not need to be taken out of the pen sleeve during use. Another situation is that the lower end of the pen sleeve is closed to protect the tip part of the pen, and the pen is taken out of the pen sleeve during use; on the inner wall of the sleeve body 1, there are anti-slip protrusions 10 that can elastically deform. When the pen is placed inside the sleeve body 1, the anti-slip protrusions 10 are deformed by the extrusion of the pen, and then give an opposite force to the pen, thereby increasing the friction between the pen and the inner wall of the sleeve body 1 and preventing the pen from falling out of the sleeve body 1. The anti-slip protrusions 10 can be convex points extending from the inner wall of the sleeve body 1, or a plurality of strip-shaped protrusions extending in the axial direction of the sleeve body 1 and arranged at intervals along the circumferential direction on the inner wall of the sleeve body 1. When the sleeve body 1 is in the up and down direction, the strip-shaped protrusions are also in the up and down direction, and then the plurality of strip-shaped protrusions are arranged at intervals along the circumferential direction of the sleeve body 1 on the inner wall of the sleeve body 1; on the outer wall of the upper part of the sleeve body 1, there is an installation seat 2. The installation seat 2 protrudes from the surface of the outer wall of the sleeve body 1. The installation seat 2 is extended from the outer wall of the upper part of the sleeve body 1 near the upper end edge position. In this way, when using the opening ring 3 provided on the installation seat 2 to hang the pen sleeve, the pen sleeve remains in a vertical state. There is a first through hole 20 on the installation seat 2 whose axial direction is perpendicular to the axial direction of the sleeve body 1. When the sleeve body 1 is placed vertically, the first through hole 20 is arranged on the installation seat 2 in the left and right direction. An opening ring 3 is movably installed in the first through hole 20, and the width of the notch of the opening ring 3 is smaller than the length of the first through hole 20. The opening ring 3 has a notch on the annular part. The opening ring 3 can rotate along the first through hole 20. By rotating the opening ring 3, the notch of the opening ring 3 is rotated out or into the first through hole 20. The opening ring 3 is selected as a circular opening ring, and the circular structure facilitates its rotation in the first through hole 20. A hanging rope (not shown in the figure) is installed inside the opening ring 3. The hanging rope can be put around the neck, and the pen sleeve can be hung in front of the chest by using the hanging rope, which is more convenient for use; the two ends of the opening ring 3 are correspondingly located on both sides inside the first through hole 20. The left end of the opening ring 3 is located on the left side inside the first through hole 20, and the right end of the opening ring 3 is located on the right side inside the first through hole 20. The width of the notch of the opening ring 3 is smaller than the length of the first through hole 20, which ensures that both ends of the opening ring 3 can be located inside the first through hole 20, preventing the pen sleeve from falling off due to the exposure of the notch of the opening ring 3; when the notch of the opening ring 3 is rotated out of the first through hole 20, it is very convenient to install the hanging rope on the opening ring 3 or hang the pen sleeve on a suitable place through the opening ring 3. When the notch of the opening ring 3 is rotated into the first through hole 20, the notch is hidden to prevent falling off;On the pore wall of the first through hole 20, there is an annular protrusion 200 that can elastically deform and part of which is located in the notch of the opening ring 3. The inner ring diameter of the annular protrusion 200 is smaller than the thickness of the opening ring 3. The annular protrusion 200 reduces the aperture of the first through hole 20. The two ends of the opening ring 3 are correspondingly located at the two ends in the axial direction of the annular protrusion 200. And the inner ring diameter of the annular protrusion 200 being smaller than the thickness of the opening ring 3 makes it impossible for the opening ring 3 to directly pass through the inner ring of the annular protrusion 200. Only by applying a force to press one end of the opening ring 3 against the annular protrusion 200 to cause the annular protrusion 200 to deform and expand the diameter of its inner ring can the opening ring 3 pass through. Then the notch of the opening ring 3 rotates out of the first through hole 20. After that, by operating in the reverse direction, the notch of the opening ring 3 can be rotated into the first through hole 20 and the annular protrusion 200 returns to its original state.;

[0024] For further improvement, as Figure 1 and Figure 4 shown in, anti-slip patterns 11 are provided at a position near the lower end of the outer wall of the sleeve body 1. At this time, the tip part of the pen can pass through the lower end of the pen sleeve. When in use, writing can be carried out without taking the pen out of the pen sleeve. For example, a polygon structure is formed by arranging a plurality of planes connected end to end in sequence along the circumferential direction of the lower end of the outer wall of the sleeve body 1, or a plurality of anti-slip stripes are arranged at intervals along the circumferential direction of the sleeve body.

[0025] For further improvement, as Figure 1 , Figure 4 and Figure 5 shown in, a sleeve body notch 12 is provided at the upper end of the sleeve body 1. A limiting member 4 for limiting the pen can be detachably installed in the sleeve body notch 12. The sleeve body notch 12 forms an avoidance space for the limiting member 4. When in use, the limiting member 4 is connected to the pen. Part of the limiting member 4 is located in the sleeve body notch 12 to prevent the pen from directly falling out of the sleeve body 1. For example, the limiting member 4 is set as a ring that can be fitted on the pen, and then an extension arm matching the sleeve body notch 12 is extended on the outer side wall of the ring. And the sleeve body notch 12 and the mounting seat 2 are correspondingly arranged on opposite sides of the sleeve body 1 to avoid mutual influence between them. For example, if the position of the mounting seat 2 on the sleeve body 1 corresponds to the rear side of the sleeve body, then the sleeve body notch 12 is arranged on the front side of the sleeve body 1.

[0026] For further improvement, as Figure 5 and Figure 6As shown in the figure, an installation post 5 is provided on the sleeve body 1. The installation post 5 covers the lower end surface of the sleeve body 1 and is coaxial with the sleeve body 1. A protective cap 6 is installed on the installation post 5. The installation post 5 extends from the lower end surface of the sleeve body 1 and is integrally formed of rubber or silica gel. Through the installation post 5, the lower end of the sleeve body 1 is closed so that the tip of the pen will not penetrate through the lower end of the sleeve body 1. At the same time, the installation post 5 can also buffer the force received by the lower end of the sleeve body 1 when the pen sleeve drops, reducing the force received by the tip of the pen installed in the sleeve body 1. In order to make the installation post 5 have a certain strength, a protective cap 6 is installed on it. The protective cap 6 is made of metal or hard plastic. A groove surrounding the installation post 5 is provided at the position where the outer wall of the installation post 5 is connected to the lower end surface of the sleeve body 1, enhancing the buffering effect of the installation post 5. The lower end of the sleeve body 1 and the protective cap 6 are both in a conical structure, which can better disperse the force received during the dropping collision and protect the pen. The installation post 5 is an installation post that can elastically deform. An installation post through hole 50 is provided on the installation post 5 along the axis. The installation post 5 is installed in the protective cap 6 by interference fit. By using the installation post through hole 50, when installing the pen into the sleeve body 1, the pen moves downward and squeezes the air in the sleeve body 1 to be discharged from the installation post through hole 50, facilitating the installation of the pen. The lower end of the sleeve body 1 and the protective cap 6 are both in a conical structure.

[0027] A pen, as Figure 1 , Figure 4 and Figure 5 shown in the figure, includes a pen body 7. The pen body 7 includes a pen barrel, a pen core installed in the pen barrel, and a plug installed at the tail of the pen barrel. The pen core is installed inside the pen barrel. The head of the plug is threadedly connected to the pen barrel and the front end of the plug presses against the tail end of the pen core. The head of the pen barrel is conical and is provided with a pen barrel through hole for the head of the pen core to penetrate. The pen body 7 is detachably and matchably installed in the portable pen sleeve described in any one of the above. The pen body 7 is inserted into the sleeve body 1 for carrying around. A sleeve notch 12 and a limiting member 4 are provided on the sleeve body 1, and the limiting member 4 is connected to the plug.

[0028] Although the present invention has been described in detail above with general descriptions and specific embodiments, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
