Description

Technical Field

[0001] The utility model belongs to the technical field of pens, in particular to an elastic pen clip and a writing pen. Background Art

[0002] Chinese patent CN204451628U discloses "A telescopic pen clip", which includes a pen clip seat and an elastic sheet, the two ends of the elastic sheet are respectively in conflict with the upper and lower limit structures in the sleeve, one end of the pen clip seat is fixed on the elastic sheet, and the other end extends out of the sleeve and is connected to the pen clip, and the pen clip seat is located in the middle of the elastic sheet. In the above scheme, the pen clip is a sheet structure, and a U-shaped elastic sheet is provided between the pen clip and the pen clip seat, which are all steel sheet structures, with high processing and molding costs, and more materials are used, and the manufacturing cost is high.

[0003] Chinese patent CN214984424U discloses a pen clip, in which one end of the pen clip body is a fixed end and the other end is a clamping end. A steel wire is wound around the side surface of the pen clip body. The portion of the steel wire near the fixed end is fixed, and the portion near the clamping end can swing with the clamping end. It has a strong clamping force and is not easy to break, but the steel wire is bent to form a structure of two parallel steel wires, and needs to be matched with the pen clip body, so the processing and manufacturing cost is high.

[0004] Chinese patent CN210390569U discloses a "clamping structure for a pen", which includes a steel wire, the middle part of which is bent to form a clamping end, one end of the steel wire is rotatably connected to the pen holder or pen cap to form a rotating end, and the other end is fixedly connected to the pen holder or pen cap to form a fixed end, and the rotating end is bent, and the bent part is perpendicular to the axial direction of the pen. The whole is formed by bending the steel wire, which is easy to install and has greater elasticity, but the clamping end is formed by the cooperation of two steel wires, which greatly increases the cost of processing and manufacturing. In addition, it is rotatably connected to the pen holder or pen cap through the rotating end, and fixedly connected to the pen holder or pen cap through the fixed end. The fixed end and the rotating end are located at different positions in the axial direction, so the force balance of the clamping object is poor.

[0005] There are also pen clips made of a single steel wire or a single steel sheet on the market, but they are restricted by the steel wire and the steel sheet themselves, resulting in relatively small clamping force. In addition, the steel wire has a cylindrical structure, and will rotate relative to the pen after being connected to it, making positioning more difficult.

[0006] In summary, there is a need in the market for a pen clip that is made of simple materials such as steel wire and steel sheet and has a strong clamping force and low manufacturing cost. Utility Model Content

[0048] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0049] Embodiment 1

[0050] like Figure 1 As shown, an elastic pen clip comprises a clamping section 1, an assembly section 2 connected to the end of the clamping section 1, and an elastic transmission section 3 connected to the end of the assembly section 2.

[0051] The clamping section 1 extends along the length of the pen and can cooperate with the outer wall of the pen to clamp an object, which can be a pocket, a book, a folder, etc. Figure 1Taking the direction shown as an example, the clamping section 1 extends up and down. The assembly section 2 is a U-shaped structure with the opening facing downward, which can be assembled with the pen. Of course, in other embodiments, it can be any shape, or it only needs to be partially U-shaped.

[0052] The elastic transmission section 3 forms a U-shaped or V-shaped structure with an opening facing upward. In the present embodiment, it is a V-shaped structure. Of course, it can also be a U-shaped structure, or at least partially a V-shaped or U-shaped structure. There is no specific limitation.

[0053] The clamping section 1, the assembly section 2 and the elastic transmission section 3 are formed by bending a metal body, and the clamping section 1, the assembly section 2 and the elastic transmission section 3 are located in the same plane. In this embodiment, the metal body is a steel wire or a steel sheet. In other words, the elastic pen clip is a single steel wire or steel sheet structure. Figure 5 The wire is shown as Figure 7 The steel sheet is shown, and this embodiment is mainly described in detail by taking the steel wire as an example. Of course, in other embodiments, the upper end of the elastic transmission section 3 is further bent to increase its contact area with the writing body 6, which is not excluded. In this case, although the clamping section 1, the assembly section 2 and the elastic transmission section 3 are not located in the same plane, most of them are located in the same plane.

[0054] When an external force is applied to move the clamping section 1 away from the outer wall of the pen, that is, Figure 1 When the clamping section 1 is bent to the left, the elastic transmission section 3 will be squeezed and deformed, and the upper opening of the V-shaped or U-shaped structure will be reduced; therefore, when the external force applied to the clamping section 1 stops, under the action of the restoring elastic force of the clamping section 1 itself, it can cooperate with the outer wall of the pen to clamp the object. At the same time, since the elastic transmission section 3 tends to restore to the original state after being deformed by the force, the upper opening of the V-shaped or U-shaped structure will expand to its original state. The restoring elastic force can also assist in providing elastic force for restoring the clamping section 1, so that the clamping force of the clamping section 1 and the outer wall of the pen on the object is greater, which solves the problem of poor clamping force of the clamping section 1 with a single steel wire structure.

[0055] Regarding the division of the clamping section 1, the assembly section 2 and the elastic transmission section 3, as shown in Figure 1 As shown, the elastic transmission section 3 can form a V-shaped or U-shaped structure alone, and the portion where the assembly section 2 and the clamping section 1 are connected can be longer; Figure 2 As shown, at this time, the elastic transmission section 3 also forms a V-shaped or U-shaped structure independently, and the portion connected to the assembly section 2 can be longer, and the portion connected to the clamping section 1 can be relatively Figure 1 The length shown is shortened; Figure 3 As shown, the elastic transmission section 3 also forms a V-shaped or U-shaped structure alone, but the length of the portion connected to the assembly section 2 is smaller, and the length of the portion connected to the clamping section 1 can be further shortened; Figure 4 As shown, at this time, the elastic transmission section 3 is only an inclined straight line section, which cooperates with part of the assembly section 2 to form a V-shaped or U-shaped structure.

[0056] The above-mentioned various forms illustrate that the division of the clamping section 1, the assembly section 2 and the elastic transmission section 3 is not specifically limited, nor is it limited to the above-mentioned embodiments. The structure of the clamping section 1 can be a linear structure or a curved structure, and there is no specific limitation.

[0057] More specifically, if Figure 6 As shown, the assembly section 2 and the elastic transmission section 3 sequentially include a first elastic section 21, a first combining section 22, a second elastic section 23, a second combining section 32, and a third elastic section 33. Figure 2 , Figure 3 As shown in the area division, the upper part of the second elastic section 23 belongs to the assembly section 2, and the lower part of the second elastic section 23 belongs to the elastic transmission section 3. Figure 4 According to the area division shown, the second elastic section 23 now belongs to the elastic transmission section 3.

[0058] In this embodiment, the first coupling section 22 is a semicircular arc structure with its opening facing downward, and the second coupling section 32 is a semicircular arc structure with its opening facing upward. The first elastic section 21 is connected to the clamping section 1, the first coupling section 22 is mounted on the pen, and the second elastic section 23 is arranged parallel to the first elastic section 21. Therefore, when an external force is applied to the clamping section 1, the first elastic section 21 can also assist the clamping section 1 in providing elastic force, and the second elastic section 23 can cooperate with the third elastic section 33 to provide greater elastic force to the clamping section 1 while providing support and elastic force to the first elastic section 21. Specifically, the clamping section 1 rotates clockwise (with an angle of 100 degrees) when subjected to an external force. Figure 5 Taking the direction shown as an example), the second elastic section 23, driven by the clamping section 1, deforms in the direction close to the third elastic section 33, so that the V-shaped or U-shaped structural angle between the second elastic section 23 and the third elastic section 33 becomes smaller. When the external force stops being applied, the deformation reset caused by the reduction of the V-shaped or U-shaped structural angle will cooperate with the first elastic section 21 to provide a larger elastic force to the clamping section 1, so that the object can be firmly clamped. In the above structure, the specific length of the elastic transmission section 3 is not limited, as long as it can increase the clamping elastic force of the clamping section 1 after extrusion deformation and reset. In this embodiment, if Figure 2 As shown, the end of the elastic transmission section 3 has an extension portion 31, which is integrally connected to the rest of the elastic transmission section 3 and is coaxial and concentric, so that the horizontal height of the end of the extension portion 31 is greater than or equal to the horizontal height of the top of the assembly section 2, that is, Figure 2In the embodiment, the horizontal height of the end of the extension portion 31 is located at the position of O1, the horizontal height of the top of the assembly section 2 is located at the position of O2, and O1 is located above O2. At this time, the elastic transmission section 3 can be deformed more after being squeezed, so when the external force is stopped, the elastic force generated by its reset is also greater, and accordingly, the clamping elastic force provided to the clamping section 1 is also greater.

[0059] like Figure 1 As shown, the vertical height of the elastic transmission section 3 is h, and the vertical height of the elastic pen clip is H, then h / H is 1 / 6-1 / 3, and preferably h / H is 1 / 6-1 / 3. The outer diameter of the steel wire is D, then D / h is 1 / 12-1 / 6, and preferably, D / h is 1 / 12-1 / 6. Under the above numerical range, it is ensured that the elastic transmission section 3 can be deformed sufficiently to assist in providing a larger restoring elastic force to the clamping section 1. At the same time, the entire volume of the elastic pen clip is relatively small, and the best elastic clamping force can be provided with the least material, and it is easy to process and shape.

[0060] A mounting ring 4 is bent at the bottom end of the clamping section 1 and is used for detachably connecting the rolling element 5. The mounting ring 4, the clamping section 1, the assembly section 2 and the elastic transmission section 3 are located in the same plane, and it should be emphasized that the four are formed by bending a steel wire or a steel sheet.

[0061] like Figure 8-Figure 10 As shown, a writing pen includes a writing body 6 and an elastic pen clip detachably connected to the writing body 6. The elastic pen clip is the above-mentioned structure and will not be described in detail. The writing body 6 has an adapter 61, which is integrally connected to the writing body 6. At this time, it can be considered that the structure on the adapter 61 also belongs to the writing body 6. Of course, the adapter 61 and the writing body 6 can also be separately set, and there is no specific limitation. In this embodiment, the outer wall of the writing body 6 has a mounting frame 68, and the adapter 61 is assembled and connected in the mounting frame 68, that is, the writing body 6 and the adapter 61 are separately set.

[0062] like Figure 11-13 As shown, the adapter 61 includes two opposite side walls 621, 622 disposed on the outer wall of the writing body 6, a hanging wall 63 located between the two opposite side walls 621, 622, and a blocking wall 64 disposed opposite to the hanging wall 63. The two opposite side walls 621, 622, the hanging wall 63 and the blocking wall 64 surround and form a top insertion opening 65, and the distance between the two opposite side walls 621, 622 is substantially equal to the outer diameter D of the steel wire. Here, the two opposite side walls 621, 622 are completely opposite to each other and are perpendicular to the outer wall of the writing body 6, while the hanging wall 63 and the blocking wall 64 are located on both sides of the two opposite side walls 621, 622, and are not completely opposite to each other.

[0063] like Figure 12-14As shown, when the elastic pen clip is assembled and connected to the writing body 6, the assembly section 2 is inserted into the hanging wall 63 from top to bottom. At this time, the clamping section 1 is against the outer wall of the hanging wall 63 (the side away from the blocking wall 64). At the same time, the elastic transmission section 3 slides against the outer wall of the writing body 6, and enters the installation space formed by the two opposite side walls 621, 622 and the hanging wall 63 from top to bottom from the top socket 65. The end of the elastic transmission section 3 falls under the blocking wall 64, and the end of the elastic transmission section 3 is against the outer wall of the writing body 6.

[0064] At this time, the end of the elastic transmission section 3 is in contact with the lower surface of the blocking wall 64. Due to the obstruction of the blocking wall 64, the elastic pen clip cannot move upward to disengage from the adapter 61. Since the end of the elastic transmission section 3 is in contact with the outer wall of the writing body 6, when an external force is applied to pry the clamping section 1 outward, the elastic transmission section 3 can be effectively squeezed and deformed under the interaction of the clamping section 1, the assembly section 2 and the writing body 6, and the deformation restoration can assist in providing elastic force for restoring the clamping section 1.

[0065] In order to prevent the clamping section 1 from shaking, the hanging wall 63 and the two opposite side walls 621, 622 cooperate to form a limiting groove 66. Fig.11 , Fig.12 As shown, the clamping section 1 and the assembly section 2 are restricted by the hanging wall 63 and the two opposite side walls 621 and 622 and will not shake left and right or move toward the writing body 6. They can only be bent away from the writing body 6 by external force.

[0066] In order to further limit the range of motion of the elastic pen clip, the horizontal height of the top of the hanging wall 63 is less than the horizontal height of the tops of the two opposite side walls 621 and 622, and the height difference between the two is greater than or equal to the diameter D of the steel wire (when the material is a steel sheet, the height difference is greater than or equal to the thickness of the steel sheet), so that the top of the elastic pen clip will not be exposed, and the overall appearance is higher. At the same time, a positioning groove 67 is formed on the outer wall of the writing body 6, and the rolling element 5 just falls into the positioning groove 67 to prevent the rolling element 5 from shifting and causing the rolling element 5 to deviate from the central axis of the writing body 6.

[0067] In order to improve the hand feeling during use, the outer wall of the writing body 6 can be covered with an elastic silicone sleeve 69 which extends over the entire height of the writing body 6 .

[0068] Embodiment 2

[0069] like Fig.15 , Fig.16 As shown, in this embodiment, the number of the clamping section 1, the assembly section 2 and the elastic transmission section 3 are all two, which are symmetrically arranged, and the two clamping sections 1 are connected in one piece.

[0070] In other words, in this embodiment, the elastic pen clip is still formed by bending a steel wire, but unlike the first embodiment, the two ends of the steel wire are bent to form a clamping section 1, an assembly section 2 and an elastic transmission section 3, that is, the elastic pen clip is a double steel wire structure. In this case, no rolling element is provided at the bottom end of the elastic pen clip, and the other structures are the same as the first embodiment, which will not be described in detail.

[0071] Correspondingly, there are two adapters 61 on the outer wall of the writing body 6, which are symmetrically arranged along the center line of the writing body. The specific structure of the adapter 61 is the same as that of the first embodiment, and will not be repeated.

[0072] The above specific implementation modes are used to explain the present invention rather than to limit the present invention. Any modification and change made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
