Description

Technical Field

[0001] This utility model relates to the field of office supplies technology, specifically to a pen grip structure. Background Technology

[0002] Existing pen grip structures typically involve attaching a grip sleeve to the handle to improve feel. For example, the grip sleeve disclosed in Chinese Utility Model Patent No. CN221584962U includes an inner grip sleeve and an outer grip sleeve with elastic deformation capability. The outer grip sleeve is fitted over the inner grip sleeve, with a gap between the inner and outer circumferential surfaces of the outer and inner grip sleeves. This gap provides space for deformation and displacement when the outer grip sleeve undergoes elastic deformation. The outer and inner grip sleeves are connected by a connecting rib. This existing pen grip structure, by designing the grip sleeve as a double-layer structure and creating a gap between the two layers, allows sufficient deformation and displacement space when the outer grip sleeve undergoes elastic deformation, greatly improving the elasticity and comfort of the grip sleeve and reducing fatigue for the writer during extended writing sessions.

[0003] However, the existing pen grip structure still has the following technical problems: the grip hardness cannot be adjusted, which makes it difficult to adjust the grip feel and meet the needs of different writing scenarios, resulting in a poor user experience. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a grip structure for a pen with adjustable grip and better user experience.

[0005] The technical solution of this utility model is: a pen grip structure, including a grip shaft and a grip sleeve disposed on the grip shaft. The grip sleeve includes an outer grip sleeve and an inner grip sleeve. The outer grip sleeve is made of a flexible material and is axially limited on the grip shaft. The inner grip sleeve is axially movable between the outer grip sleeve and the grip shaft, so that the inner grip sleeve can extend into or retract from the outer grip sleeve.

[0006] With the above structure, this utility model has the following advantages: The grip structure of this utility model pen not only features a double-layered grip, but also allows the inner grip to move axially within the outer grip. When the inner grip extends into the outer grip, the outer grip is filled with the inner grip, resulting in a firmer grip. When the inner grip retracts from the outer grip, a gap forms between the outer grip and the handle, resulting in a softer grip. Therefore, by adjusting the axial position of the inner grip, the firmness of the grip can be adjusted, making the grip adjustable to meet the needs of different writing scenarios and providing a superior user experience.

[0007] Preferably, the device further includes a rotating component disposed outside the inner grip sleeve. The rotating component is axially limited and rotatably mounted on the grip bar portion, and is linked to the inner grip sleeve. When the rotating component is rotated circumferentially, the inner grip sleeve moves axially within the outer grip sleeve. Using a rotating component to adjust the axial position of the inner grip sleeve not only results in a simple structure and convenient adjustment, but also effectively conceals the inner grip sleeve within the rotating component and the outer grip sleeve.

[0008] Preferably, the outer side of the inner grip is connected to the rotating component via a threaded connection, and the inner side of the inner grip is connected to the grip bar via an axial guide structure. This configuration reliably converts the rotational motion of the rotating component into the axial motion of the inner grip; the conversion structure is simple and easy to implement.

[0009] Preferably, the threaded connection structure includes an external thread on the outer circumferential surface of the inner gripper and an internal thread on the inner circumferential surface of the rotating component. The inner gripper is partially provided with the external thread along the axial direction, while the rotating component is entirely provided with the internal thread along the axial direction. The fact that the rotating component is entirely provided with the internal thread along the axial direction ensures the required adjustment range of the inner gripper, while the fact that the inner gripper is partially provided with the external thread along the axial direction reduces the friction between the inner gripper and the rotating component, making the helical motion smoother.

[0010] Preferably, the axial guide structure includes a guide slider disposed on one of the grip portion and the inner grip sleeve, and a guide groove disposed on the other. This axial guide structure is simple and compact.

[0011] Preferably, two guide sliders and two guide grooves are symmetrically arranged on both sides. This arrangement makes the force on both sides of the inner grip more balanced, improves the axial guiding effect, and makes the movement more stable.

[0012] Preferably, the guide groove is axially formed on the side wall of the inner grip sleeve, and one end of the guide groove extends to the end face of the inner grip sleeve to form an opening. The guide slider on the grip bar is installed into the guide groove of the inner grip sleeve through the opening. This arrangement facilitates the installation of the guide slider into the guide groove using the opening, making installation more convenient.

[0013] Preferably, when the inner grip sleeve slides axially on the grip bar, the guide slider remains within the guide groove. This design prevents the guide slider on the grip bar from disengaging from the guide groove of the inner grip sleeve through the opening, thus ensuring that the grip bar always provides axial guidance for the inner grip sleeve when it slides axially.

[0014] Preferably, one end of the grip is also provided with a pen tip sleeve, and the outer grip sleeve is sandwiched between the pen tip sleeve and the rotating component. This arrangement is reasonable and conforms to user habits, making it convenient to hold the fingers on the outer grip sleeve and to adjust the rotating component.

[0015] Preferably, a first annular limiting step and a second annular limiting step are respectively provided on the outer peripheral surface of the grip portion and above the rotating member and the inner grip sleeve. A third annular limiting step is also provided inside the outer grip sleeve near the pen tip sleeve. The outer grip sleeve and the rotating member are axially limited between the pen tip sleeve and the first annular limiting step, while the inner grip sleeve moves axially between the second annular limiting step and the third annular limiting step. This configuration utilizes the simple first, second, and third annular limiting steps to achieve axial limiting of the inner grip sleeve, outer grip sleeve, and rotating member.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0018] like Figures 1-6As shown, a pen grip structure includes a grip 1 and a grip sleeve 2 disposed on the grip 1. The grip sleeve 2 includes an outer grip sleeve 3 and an inner grip sleeve 4. The outer grip sleeve 3 is made of a flexible material and is axially limited on the grip 1. The inner grip sleeve 4 is axially movable between the outer grip sleeve 3 and the grip 1, so that the inner grip sleeve 4 can extend into or retract from the outer grip sleeve 3. In this embodiment, the outer grip sleeve 3 can be made of any flexible material such as rubber, silicone, soft plastic, or cork. The inner grip sleeve 4 can be made of either a flexible material or a rigid material. The flexible material is the same as the outer grip sleeve 3, and the rigid material is such as hard plastic or metal. "Up," "Down," "Left," and "Right" are indicated by... Figure 1 As the standard.

[0019] The grip structure of this utility model pen not only features a double-layered grip 2, but also allows the inner grip 4 to move axially within the outer grip 3. When the inner grip 4 extends into the outer grip 3, the outer grip 3 is filled with the inner grip 4, resulting in a firmer grip. When the inner grip 4 retracts from the outer grip 3, a gap forms between the outer grip 3 and the handle 1, resulting in a softer grip. Therefore, by adjusting the axial position of the inner grip 4, the firmness of the grip 2 can be adjusted, making the grip adjustable to meet the needs of different writing scenarios and providing a better user experience.

[0020] It also includes a rotating component 5 disposed outside the inner grip sleeve 4. The rotating component 5 is axially limited and rotatably mounted on the grip bar portion 1, and the rotating component 5 is linked to the inner grip sleeve 4. When the rotating component 5 is rotated circumferentially, the inner grip sleeve 4 moves axially within the outer grip sleeve 3. Using the rotating component 5 to adjust the axial position of the inner grip sleeve 4 is not only simple in structure and convenient in adjustment, but also allows the inner grip sleeve 4 to be well hidden within the rotating component 5 and the outer grip sleeve 3.

[0021] The outer side of the inner grip 4 is connected to the rotating component 5 via a threaded connection structure 6, and the inner side of the inner grip 4 is connected to the grip bar portion 1 via an axial guide structure 7. This configuration reliably converts the rotational motion of the rotating component 5 into the axial motion of the inner grip 4. The conversion structure is simple and easy to implement.

[0022] The threaded connection structure 6 includes an external thread 8 on the outer circumferential surface of the inner gripper 4 and an internal thread 9 on the inner circumferential surface of the rotating component 5. The inner gripper 4 is partially provided with the external thread 8 along the axial direction, while the rotating component 5 is entirely provided with the internal thread 9 along the axial direction. The fact that the rotating component 5 is entirely provided with the internal thread 9 along the axial direction ensures the required adjustment range of the inner gripper 4, while the fact that the inner gripper 4 is partially provided with the external thread 8 along the axial direction reduces the friction between the inner gripper 4 and the rotating component 5, making the helical movement smoother.

[0023] The axial guide structure 7 includes a guide slider 10 disposed on one of the grip portion 1 and the inner grip sleeve 4, and a guide groove 11 disposed on the other. The axial guide structure 7 is simple and compact.

[0024] Two guide sliders 10 and two guide grooves 11 are symmetrically arranged on the left and right sides. This arrangement makes the force on both sides of the inner grip sleeve 4 more balanced, the axial guiding effect better, and the movement more stable.

[0025] A guide groove 11 is axially formed on the side wall of the inner grip sleeve 4, and one end of the guide groove 11 extends to the end face of the inner grip sleeve 4 to form an opening 12. The guide slider 10 on the grip bar 1 is installed into the guide groove 11 of the inner grip sleeve 4 through the opening 12. This arrangement facilitates the installation of the guide slider 10 into the guide groove 11 using the opening 12, making installation more convenient.

[0026] When the inner grip 4 slides axially on the grip 1, the guide slider 10 remains within the guide groove 11. This design prevents the guide slider 10 on the grip 1 from disengaging from the guide groove 11 of the inner grip 4 through the opening 12, thus ensuring that the grip 1 always provides axial guidance for the inner grip 4 when it slides axially.

[0027] One end of the grip portion 1 is also provided with a pen tip sleeve 13, and the outer grip sleeve 3 is sandwiched between the pen tip sleeve 13 and the rotating component 5. This arrangement is reasonable and conforms to user habits, making it convenient to hold the fingers on the outer grip sleeve 3 and to adjust the rotating component 5.

[0028] On the outer circumferential surface of the grip portion 1, above the rotating component 5 and the inner grip sleeve 4, there are respectively a first annular limiting step 14 and a second annular limiting step 15. The outer grip sleeve 3, near the end of the pen tip sleeve 13, also has a third annular limiting step 16. The outer grip sleeve 3 and the rotating component 5 are axially limited between the pen tip sleeve 13 and the first annular limiting step 14, while the inner grip sleeve 4 moves axially between the second annular limiting step 15 and the third annular limiting step 16. In this embodiment, the first annular limiting step 14 is located above the second annular limiting step 15. This arrangement utilizes the simple structure of the first annular limiting step 14, the second annular limiting step 15, and the third annular limiting step 16 to achieve axial limiting of the inner grip sleeve 4, the outer grip sleeve 3, and the rotating component 5.

[0029] In this embodiment, the pen tip sleeve 13 is threadedly connected to the grip part 1. Of course, the pen tip sleeve 13 can also be integrally formed with the grip part 1. The guide groove 11 of the inner grip sleeve 4 forms an opening 12 at the upper end, and the external thread 8 is only provided at the upper end of the inner grip sleeve 4.

[0030] The working principle of the pen grip structure in this embodiment is as follows: Installation process: Remove the pen tip sleeve 13, align the opening 12 of the guide groove 11 of the inner grip sleeve 4 with the guide slider 10 of the grip part 1 and insert it; then install the rotating part 5 onto the grip part 1 and put it on the outside of the inner grip sleeve 4; then put the outer grip sleeve 3 on the outside of the inner grip sleeve 4 and below the rotating part 5, and then screw on the pen tip sleeve 13. After installation, the outer grip sleeve 3 and the rotating part 5 are axially limited between the pen tip sleeve 13 and the first annular limiting step 14.

[0031] Grip adjustment process: Rotate the rotating part 5 clockwise or counterclockwise. While the rotating part 5 drives the inner grip 4 to move in a spiral motion, the axial guiding effect of the guide slider 10 and the guide groove 11 causes the inner grip 4 to move axially on the grip bar 1, so that the inner grip 4 can extend into or retract from the outer grip 3. When the inner grip 4 extends into the outer grip 3, the interior of the outer grip 3 is filled by the inner grip 4, and the grip feels harder. When the inner grip 4 retracts from the outer grip 3, a gap is formed between the outer grip 3 and the grip bar 1, and the grip feels softer.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
