Description

Technical Field

[0001] This utility model belongs to the field of pen technology, and in particular relates to a writing pen. Background Technology

[0002] Chinese patent CN210591126U discloses a "Connection Structure between a Wire Pen Clip and a Pen," in which the pen clip consists of a single wire. The wire is bent in the middle to form a clamping end. One end of the wire is rotatably connected to a connecting block to form a rotating end, and the other end is fixedly connected to the connecting block to form a fixed end. The connecting block has a shaft hole and a fixing hole for the rotating end and the fixed end to be inserted, respectively, and the fixing hole and the shaft hole are arranged perpendicularly. The bending structure of the wire is relatively complex, and a connecting block needs to be set on the outer wall of the pen barrel, making processing relatively inconvenient. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a writing pen in which the connecting part of the pen clip is installed into the receiving cavity along the radial direction of the pen barrel. The installation operation is simple and the installation structure is stable.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a writing pen, including a pen barrel, a pen core assembly, and a pen clip. The pen barrel has a receiving cavity with an installation opening facing the side wall of the pen barrel. The side wall of the pen barrel forms a through groove corresponding to the installation opening. The pen clip includes a clamping part and a connecting part. The connecting part can undergo elastic deformation under external force. The maximum width of the connecting part is greater than the maximum width of the installation opening. When the connecting part is squeezed and deformed, and passes through the installation opening along the radial direction of the pen barrel into the receiving cavity, it is limited and abuts against the inner wall of the receiving cavity.

[0005] Furthermore, the pen clip is formed by bending a steel wire, and the connecting part is a V-shaped structure formed by bending a steel wire. After passing through the through groove and the installation opening along the radial direction of the pen barrel and entering the receiving cavity, the closed end and the open end respectively abut against the inner wall of the receiving cavity.

[0006] Furthermore, the mounting opening extends along the axial direction of the pen barrel, and the opening of the connecting part faces the mounting opening.

[0007] Furthermore, the inner wall of the receiving cavity is fitted to the side wall of the connecting part.

[0008] Furthermore, the pen barrel is provided with an installation component that abuts against the pen refill assembly, and the receiving cavity is formed by hollowing out the inside of the installation component; the installation component forms a retaining edge at the installation opening that abuts against the connecting part.

[0009] Furthermore, the through groove extends along the axis of the pen barrel and its length is greater than the length of the installation opening. The pen refill assembly is a press-out structure, and the pen clip can move up and down within the through groove to press the pen refill assembly.

[0010] Furthermore, a pressing portion is formed between the connecting portion and the clamping portion, which extends away from the outer wall of the pen barrel to provide an area for the operator to apply force when pressing down on the pen clip.

[0011] Furthermore, the pressing part is perpendicular to the outer wall of the pen barrel.

[0012] Furthermore, the end of the clamping part away from the connecting part is bent to form an adapter ring, which is connected to a ball bearing.

[0013] Furthermore, an erasable pen tip is detachably connected to the top of the pen barrel.

[0014] The beneficial effects of this utility model are as follows: Utilizing the elastic deformation characteristic of the connecting part, the connecting part is inserted radially into the receiving cavity along the pen barrel. Once inside the cavity, it returns to its original shape, thus achieving a stable connection between the pen clip and the pen barrel. Operation is simple and convenient. The connecting part is restrained and abutted against the inner wall of the receiving cavity, preventing swaying or shaking, ensuring a stable and effective connection structure. The pen clip is formed by bending a single steel wire into a V-shape, enabling the elastic deformation of the connecting part. This design is easy to manufacture and has low processing costs. The installation opening extends along the axial direction of the pen barrel, so the opening of the connecting part faces the side wall of the pen barrel, eliminating the need to insert the pen clip directly into the barrel. The design is reasonable, as the outer diameter of the pen shaft can be increased to facilitate installation. The connecting part is inserted into the receiving cavity along the radial direction of the pen shaft. Compared with the wire clip, which is installed from top to bottom to the pen shaft, the top of the through groove does not need to extend to the top of the pen shaft. The length of the through groove can be designed according to the stroke of pressing out the lead and can be designed at any height of the pen shaft without creating an additional opening on the outer wall of the pen shaft, resulting in a more aesthetically pleasing appearance. The setting of the pressing part provides more force space for pressing down the pen clip to release the lead assembly, making operation more convenient. The ball can rotate relative to the pen clip. When the ball moves relative to the pen shaft with the pen clip, the frictional damage to the outer wall of the pen shaft is reduced, and the movement of the pen clip is smoother.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0026] like Figures 1-3 As shown, a writing pen includes a pen barrel 1, a refill assembly 2 disposed within the pen barrel 1, and a pen clip 3. The pen barrel 1 has a receiving cavity 41 with an installation opening 411 facing the side wall of the pen barrel 1. A through groove 11 is formed on the side wall of the pen barrel 1 corresponding to the installation opening 411. The pen clip 3 includes a clamping part 31 and a connecting part 32. The connecting part 32 can elastically deform under external force, meaning its maximum width can decrease under external force, but it returns to its original shape once the external force is removed. When no external force is applied, the maximum width of the connecting part 32 is greater than the maximum width of the installation opening 411. When the connecting part 32 is compressed and deformed, and passes through the installation opening 411 radially along the pen barrel 1 into the receiving cavity 41, the connecting part 32 abuts against the inner wall of the receiving cavity 41.

[0027] The above structure does not limit the specific structure and shape of the connecting part 32, nor does it limit the extension direction of the mounting opening 411. The mounting opening 411 can extend along the plane containing the diameter of the pen barrel 1, or it can extend along the axis of the pen barrel 1. There is no specific limitation. It should be noted that the connecting part 32 is limited to abutting against the inner wall of the receiving cavity 41. The number of abutting points is not limited, as long as it can ensure that the connecting part 32 does not move or swing within the receiving cavity 41.

[0028] In this embodiment, the pen clip 3 is formed by bending a steel wire, and the connecting part 32 is a V-shaped structure formed by bending the end of the steel wire. After passing through the through groove 11 and the mounting opening 411 along the radial direction of the pen barrel 1 and entering the receiving cavity 41, the closed end 321 and the open end 322 respectively abut against the inner wall of the receiving cavity 41.

[0029] The above structure does not limit the orientation of the opening of the connecting part 32. The opening can extend along the length direction of the pen barrel 1, and its open end 322 can be located below or above the closed end 321. Of course, the opening can also extend along the plane of the diameter of the pen barrel 1, and its open end 322 can be located to the left or right of the closed end 321. There are no specific restrictions.

[0030] like Figures 3-5 As shown, in this embodiment, the opening of the connecting part 32 extends along the length direction of the pen barrel 1, and the open end 322 is located below the closed end 321, that is, the opening of the connecting part 32 is set to the right and downward in the figure. The mounting opening 411 extends along the axial direction of the pen barrel 1, and the opening of the connecting part 32 faces the mounting opening 411, that is, the opening of the connecting part 32 and the mounting opening 411 are directly opposite each other.

[0031] The above structure does not limit the formation method of the receiving cavity 41. It can be directly integrally formed in the pen barrel 1, or it can be formed by other components and then installed into the pen barrel 1. In this embodiment, a mounting member 4 is provided in the pen barrel 1, which abuts against the pen refill assembly 2, and the receiving cavity 41 is formed by hollowing out the inside of the mounting member 4.

[0032] Specifically, such as Figure 6 , Figure 7 As shown, the mounting component 4 includes an upper body 42 and a lower body 43. The lower body 43 is detachably connected to the pen refill assembly 2. In this embodiment, the pen refill assembly 2 is a press-to-extract structure as in the prior art. The lower body 43 is sleeved and connected inside the push-button 21 of the pen refill assembly 2, and the two are detachably limited and connected by a protruding ring 431. The upper body 42 forms a receiving cavity 41, the width of which is approximately equal to the outer diameter of the steel wire. Thus, when the connecting part 32 is limited and abuts against the receiving cavity 41, the inner wall of the receiving cavity 41 fits against the side wall of the connecting part 32, preventing the connecting part 32 from shaking within the receiving cavity 41.

[0033] The mounting member 4 forms a retaining edge 44 at the mounting opening 411, which abuts against the connecting portion 32, specifically against the open end 322 of the connecting portion 32. In this embodiment, the open end 322 is located below the closed end 321, thus the retaining edge 44 is located below the mounting opening 411. When the connecting portion 32 is inserted into the receiving cavity 41, the closed end 321 abuts against the inner wall of the mounting member 4, the open end 322 abuts against the retaining edge 44, and the top of the connecting portion 32 abuts against the top surface of the mounting opening 411. Therefore, the connecting portion 32 will not wobble or shift in any direction, and the mounting structure is stable.

[0034] The pen refill assembly 2 can be a rotating refill structure, a pressing refill structure, or any structure in the prior art. In this embodiment, a pressing refill structure is selected. To facilitate the axial movement of the pen clip 3 relative to the pen barrel 1, the through groove 11 extends along the axial direction of the pen barrel 1, and its length is greater than the length of the mounting opening 411. Thus, an external force is applied to the pen clip 3 to make it move up and down within the through groove 11, thereby pressing the pen refill assembly 2 to dispense the refill.

[0035] To facilitate the operator's pressing and applying force on the pen clip 3, a pressing part 33 is formed between the connecting part 32 and the clamping part 31. This pressing part 33 extends away from the outer wall of the pen barrel 1, thereby providing an area for the operator to apply force when pressing down on the pen clip 3. In this embodiment, the pressing part 33 is perpendicular to the outer wall of the pen barrel 1, that is, the pressing part 33 and the clamping part 31 are perpendicular to each other. In other words, the clamping part 31 can be set closer to the outer wall of the pen barrel 1. Here, the part parallel to the outer wall of the pen barrel 1 is defined as the clamping part 31. In this case, when the operator wants to press down on the pen clip 3, external force can only be applied in a small area between the clamping part 31 and the connecting part 32, or even only on the clamping part 31, which is relatively inconvenient. The setting of the pressing part 33 makes the distance between the clamping part 31 and the outer wall of the pen barrel 1 larger, which not only allows the pen clip 3 to clamp thicker objects, but also provides a force application space for pressing down on the pen clip 3 to release the pen lead assembly 2, making the operation more convenient.

[0036] like Figures 8-9 As shown, the end of the clamping part 31 away from the connecting part 32 is bent to form a transition ring 311. The transition ring 311 is connected to a ball bearing 34, which can rotate around its own axis within the transition ring 311. Thus, when the pen clip 3 moves up and down relative to the pen barrel 1, the ball bearing 34 moves with the pen clip 3 relative to the pen barrel 1, reducing frictional damage to the outer wall of the pen barrel 1 and making the movement of the pen clip 3 smoother.

[0037] like Figure 1 , Figure 2As shown, an erasable pen tip 5 is detachably connected to the top of the pen barrel 1. In order to prevent the mounting part 4 from moving, a fixing sleeve 6 is snapped between the erasable pen tip 5 and the mounting part 4. The upper and lower ends of the fixing sleeve 6 abut against the erasable pen tip 5 and the mounting part 4, respectively.

[0038] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
