Description

Technical Field

[0001] This utility model relates to the field of whiteboard marker technology, and in particular to a universal magnetic whiteboard marker. Background Technology

[0002] In teaching and business training, chalk and blackboards, whiteboard markers and hard whiteboards, and electronic writing screens are commonly used for recording teaching content. However, chalk and blackboards easily produce dust, which can have a certain impact on users' health. Electronic writing screens consume a lot of electricity and usually require an additional blackboard or hard whiteboard, making them relatively inconvenient to use. Ordinary whiteboard markers and hard whiteboards do not produce much dust and are therefore popular. However, erasing them after writing is time-consuming and laborious, and ordinary whiteboard markers rely on ink to leave marks on hard whiteboards, so they need to be replaced when the ink runs out, causing inconvenience.

[0003] With the advancement of technology and the increasing demands of consumers for the performance of electronic products, magnetic writing board technology has gradually developed. The magnetic writing film of the magnetic writing board has the advantages of being pollution-free and dust-free. The magnetic writing film is composed of light-absorbing magnetic particles and light-reflecting non-magnetic particles mixed into a volatile dispersion. When a magnetic whiteboard pen with magnetic adsorption writes on the magnetic writing film, it can attract the light-absorbing magnetic particles to the surface of the magnetic writing film, thereby displaying the written content on the surface of the magnetic writing film.

[0004] However, the pen tip of current magnetic whiteboard markers is fixed and the angle cannot be changed. This means that writers can only create continuous handwriting on the magnetic writing film when they form a very small angle between the pen tip and the magnetic writing film. This results in inconvenience and poor writing quality.

[0005] Therefore, there is an urgent need to provide a universal magnetic whiteboard marker that is easy to use and has excellent writing performance. Utility Model Content

[0006] To address the shortcomings of existing technologies, such as inconvenience in use and poor writing quality, this utility model provides a universal magnetic whiteboard pen, comprising: a pen tube with a hollow portion; a pen end sleeve fitted into the first end opening of the pen tube, the pen end sleeve having a sleeve hole; an adapter assembly including a ball head extending outward from the sleeve hole; and a magnetic pen tip assembly including a magnetic block rotatably connected to the ball head, the magnetic block being able to deflect at multiple angles relative to the central axis of the pen tube along with the magnetic pen tip assembly.

[0007] Furthermore, the adapter assembly also includes an abutment sleeve that can be axially displaced within the sleeve hole to maintain elastic abutment against the magnetic pen tip assembly in response to the deflection of the magnetic pen tip assembly.

[0008] Furthermore, the adapter also includes a support rod and an elastic element. The ball head is fixed to the first end of the support rod, and the abutment sleeve has a through hole. The second end of the support rod, which is opposite to the first end, passes through the through hole and rotates to connect the magnetic pen tip assembly with the ball head located outside the pen tip sleeve. The elastic element elastically presses against the force-bearing end of the abutment sleeve away from the magnetic pen tip assembly.

[0009] Furthermore, the adapter assembly also includes a first retaining ring and a second retaining ring. A first retaining groove that engages with the first retaining ring and a second retaining groove that engages with the second retaining ring are provided at intervals along the axial direction on the support rod. The end face of the abutment sleeve facing away from the ball head is provided with a sleeve post and a force-bearing end face surrounding the sleeve post. The force-bearing end face is designated as the force-bearing end. The elastic element is sleeved around the outer periphery of the sleeve post and elastically compressed between the first retaining ring and the force-bearing end face. The sleeve hole includes a first sleeve hole and a second sleeve hole that are connected to each other. The first sleeve hole is provided with a first limiting surface that engages with the first retaining ring at the end closer to the magnetic pen tip assembly. The end face of the pen tip sleeve facing the hollow part is provided with a second limiting surface that engages with the second retaining ring.

[0010] Furthermore, the pen tip sleeve includes a sleeve arranged in the second sleeve hole and multiple support blocks. The multiple support blocks are connected to the inner wall of the pen tip sleeve in the radial direction and extend along the axial direction of the pen tip sleeve. The outer periphery of the sleeve is connected to each support block. The support rod passes through the tube hole of the sleeve. The second limiting surface is the tube end face of the sleeve.

[0011] Furthermore, the adapter also includes a third retaining ring. A third retaining groove is provided on the support rod along the axial direction between the first retaining groove and the second retaining groove. The third retaining ring engages with the third retaining groove. A third limiting surface is also provided at the intersection of the first and second sleeve holes of the pen tip sleeve, which engages with the third retaining ring for limiting.

[0012] Furthermore, the central axes of the pen tube, pen tip sleeve, abutment sleeve, and support rod are located on the same axis, and the elastic element is set as a spring.

[0013] Furthermore, the magnetic pen tip assembly also includes an outer shell, an inner shell, and a receiving shell. The inner shell is arranged inside the outer shell and fixedly connected to it. The receiving shell is arranged inside the inner shell and fixedly connected to it. The magnetic block is fixed in the receiving shell. The inner shell is provided with a first spherical notch that matches the ball head. The outer shell is provided with a through hole with a diameter smaller than the diameter of the ball head. The second end of the support rod passes through the hole and through the through hole, so that the support rod extends into the hollow part.

[0014] Furthermore, the outer shell, inner shell, and receiving shell all have open ends on the side of the shell facing away from the pen tip sleeve. The open ends are opposite to the magnetic block. The inner shell and receiving shell are provided with fixing holes. The fixing post is fixedly connected to the fixing holes to fix the inner shell and the receiving shell and limit the position of the magnetic block in the receiving shell. At least the magnetically permeable sliding plate is arranged in the open end of the outer shell.

[0015] Furthermore, the outer circumferential surfaces of the outer shell, inner shell, and receiving shell are all cylindrical, with the cylindrical surface of the outer shell fitting onto the cylindrical surface of the inner shell. The magnetic block is rectangular in shape, the outer shell is made of metal, and the inner shell is made of plastic.

[0016] The beneficial effects of this utility model are as follows:

[0017] The universal magnetic whiteboard pen provided by this utility model is rotatably connected to the ball head of the adapter assembly through a magnetic pen tip assembly. As a result, the magnetic block of the magnetic pen tip assembly can rotate and the angle can be changed, which allows the writer to easily form continuous handwriting on the writing board. It has the advantages of being easy to use and having a good writing effect. Attached Figure Description

It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element limited by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. Unless otherwise specified, embodiments of the present invention and the various features thereof can be combined with each other, all within the protection scope of the present invention.

[0027] See Figures 1 to 5As the purpose of this utility model, a universal magnetic whiteboard marker is provided, comprising a pen tube 1 with a hollow portion, a pen tip sleeve 2, an adapter assembly 3, and a magnetic pen tip assembly 4. The pen tip sleeve 2 is fitted into the first end opening of the pen tube 1, and the pen tail is provided at the second end opening of the pen tube 1 opposite to the first end opening. The pen tip sleeve 2 has a sleeve hole 11. The adapter assembly 3 includes a ball head 31 extending outward from the sleeve hole 11. The magnetic pen tip assembly 4 includes a magnetic block 41 and is rotatably connected to the ball head 31. The magnetic block 41 can deflect at multiple angles relative to the central axis of the pen tube 1 along with the magnetic pen tip assembly 4. Therefore, since the magnetic pen tip assembly 4 is rotatably connected to the ball head 31 of the adapter assembly 3, the magnetic block 41 of the magnetic pen tip assembly 4 is rotatable and its angle is variable. This allows the writer to write within a large angle range between the pen tip and the magnetic writing film of the magnetic writing board, and to form continuous handwriting on the magnetic writing film. Thus, it has the advantages of being easy to use and having a good writing effect.

[0028] Please refer to the above. Figure 3 Specifically, the adapter component 3 also includes an abutment sleeve 32, which can be axially displaced within the sleeve hole 11 to maintain elastic contact with the magnetic pen tip assembly 4 in response to the deflection of the magnetic pen tip assembly 4. In this way, by using the abutment sleeve 32 to maintain elastic contact with the magnetic pen tip assembly 4, especially to maintain the deflection angle of the magnetic block 41, the angle will not change arbitrarily during writing. This allows the writer to apply the same writing force relative to the same angle of the magnetic block 41 in at least one writing process, resulting in continuous and uniform handwriting.

[0029] Please refer to the above. Figure 3 Specifically, the adapter assembly 3 also includes a support rod 33 and an elastic element 34. The ball head 31 is fixed to the first end of the support rod 33. The abutment sleeve 32 has a through hole 321. The second end of the support rod 33, opposite to the first end, passes through the through hole 321 and rotatably connects the ball head 31 to the magnetic pen tip assembly 4 located outside the pen tip sleeve 2. The elastic element 34 elastically presses against the force-bearing end of the abutment sleeve 32 away from the magnetic pen tip assembly 4. In this way, the support rod 33 has high strength, ensuring a stable connection between the ball head 31 and the magnetic pen tip assembly 4, and the elastic restoring force of the elastic element 34 has good stability, ensuring that the abutment sleeve 32 continuously applies the desired force to the magnetic pen tip assembly 4.

[0030] Please refer to the above. Figure 3 and Figure 5Specifically, the adapter assembly 3 also includes a first retaining ring 35 and a second retaining ring 36. The support rod 33 is provided with a first retaining groove 331 that engages with the first retaining ring 35 and a second retaining groove 332 that engages with the second retaining ring 36 at intervals along the axial direction. The end face of the abutting sleeve 32 facing away from the ball head 31 is provided with a sleeve post 322 and a force-bearing end face surrounding the sleeve post 322. The force-bearing end face is designated as the force-bearing end. The elastic element 34 is sleeved on the outer periphery of the sleeve post 322 and elastically compressed between the first retaining ring 35 and the force-bearing end face. The sleeve hole 11 includes a first sleeve hole 111 and a second sleeve hole 112 that are connected. The first sleeve hole 111 is provided closer to one end of the magnetic pen tip assembly 4 and is provided with a first limiting surface 12 that engages with the first retaining ring 35. The end face of the pen tip sleeve 2 facing the hollow part is provided with a second limiting surface that engages with the second retaining ring 36. Therefore, the position of the support rod 33 in the pen tube 1 and the pen tip sleeve 2 can be accurately limited, and the two ends of the elastic element 34 can be reliably limited axially upward, so that when the abutment sleeve 32 is subjected to the force from the magnetic pen tip assembly 4, especially the outer shell 42 described below, the elastic element 34 will not deflect when it is elastically compressed by the abutment sleeve 32.

[0031] Please refer to the above. Figure 4 and Figure 5 Specifically, the pen tip sleeve 2 includes a sleeve 13 arranged in the second sleeve hole 112 and multiple support blocks 15. The multiple support blocks 15 are radially connected to the inner wall of the pen tip sleeve 2 and extend along the axial direction of the pen tip sleeve 2. The outer periphery of the sleeve 13 is connected to each support block 15. The support rod 33 passes through the through hole of the sleeve 13, and the second limiting surface is the tube end face 131 of the sleeve 13. In this way, not only is the overall strength of the pen tip sleeve 2 increased, thus providing a better positioning effect for the support rod 33, but it also ensures that the second retaining spring 36 is reliably limited.

[0032] Please refer to the above. Figure 3 and Figure 5 Specifically, the adapter assembly 3 also includes a third retaining spring 37. A third retaining groove 333 is also provided on the support rod 33 along the axial direction between the first retaining groove 331 and the second retaining groove 332. The third retaining spring 37 engages with the third retaining groove 333. A third limiting surface 14, which engages with the third retaining spring 37, is also provided at the intersection of the first sleeve hole 111 and the second sleeve hole 112 of the pen tip sleeve 2. This further enhances the limitation on the position of the support rod 33.

[0033] Please refer to the above. Figure 3 Specifically, the central axes of the pen tube 1, pen tip sleeve 2, abutment sleeve 32 and support rod 33 are located on the same axis, which can improve the grip writing feel and control force. The elastic element 34 is set as a spring, which facilitates assembly and saves costs.

[0034] Please refer to the above. Figure 3 Specifically, the magnetic pen tip assembly 4 also includes an outer shell 42, an inner shell 43, and a receiving shell 44. The inner shell 43 is arranged within and fixedly connected to the outer shell 42, and the receiving shell 44 is arranged within and fixedly connected to the inner shell 43. The magnetic block 41 is fixed in the receiving shell 44. The inner shell 43 is provided with a first spherical notch that matches the ball head 31. The outer shell 42 is provided with a through hole 421 with a diameter smaller than that of the ball head 31, so that the assembled ball head 31 cannot detach from the outer shell 42, i.e., relative to the magnetic pen tip assembly 4. The second end of the support rod 33 passes through the hole 421 and through the through hole 321, so that the support rod 33 extends into the hollow part. Therefore, the magnetic pen tip assembly 4 not only has a compact overall structure, but the magnetic block 41 can also be reliably fixed.

[0035] Please refer to the above. Figure 3 and Figure 4 Specifically, the outer shell 42, inner shell 43, and receiving shell 44 all have open ends (not shown) on the side of the shell facing away from the pen tip sleeve 2. The open ends are opposite to the magnetic block 41, thereby preventing the loss of magnetic force on the magnetic block 41. The inner shell 43 and receiving shell 44 are provided with fixing holes 431. The fixing post is fixedly connected to the fixing holes 431 to fix the inner shell 43 and the receiving shell 44 and limit the position of the magnetic block 41 in the receiving shell 44. Therefore, the magnetic block 41 will not shake in the receiving shell 44. At least the magnetic sliding plate is arranged in the open end of the outer shell 42, which makes writing smooth while avoiding wear on the magnetic writing board.

[0036] Please refer to the above. Figure 3 Specifically, the outer periphery of the outer shell 42, the inner shell 43, and the receiving shell 44 are all cylindrical. The cylindrical surface of the outer shell 42 fits onto the cylindrical surface of the inner shell 43, which makes assembly convenient and the structure aesthetically pleasing. The magnetic block 41 is rectangular. The outer shell 42 is made of metal and the inner shell 43 is made of plastic. This ensures the durability of the magnetic pen tip assembly 4 while also reducing weight, thus reducing the effort required for writing and gripping.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
