Description
Technical Field
[0001] The present application relates to the technical field of stationery, and in particular to a whiteboard pen. Background Art
[0002] A whiteboard pen is a tool for writing on a whiteboard, similar to chalk on a blackboard. This pen uses ink as ink, can be written on a smooth whiteboard, and can be wiped off with a whiteboard eraser. Whiteboard pens contain chemical raw materials and have a chemical smell. After the ink solidifies, a layer of mucus forms on the surface, and after wiping, it becomes strips or block particles. No stains remain on the board or the eraser. During field testing, you can use your fingers instead of the eraser to wipe and test its effect. When writing, you don't need to put on the pen cover, it will never dry out, and you can write smoothly.
[0003] In the prior art, when the ink bag of a whiteboard pen needs to be replaced after the ink is used up, the back cover needs to be unscrewed first, and then the ink bag needs to be replaced. Since the back cover is generally small, the contact area between the back cover and the finger is small and the friction is small. When the writer twists the back cover, it is difficult to exert force with his fingers, and the operation is inconvenient. Therefore, an improvement is now made to a whiteboard pen. Utility Model Content
[0004] In view of the deficiencies in the prior art, the present application provides a whiteboard pen, which overcomes the deficiencies in the prior art and aims to solve the problems in the prior art.

[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0031] Refer to Figures 1-5 , a whiteboard pen, including a pen barrel 1, a pen tip 4 is fixedly installed at a position near the front end inside the pen barrel 1, a disposable ink sac 9 is slidably inserted at a position near the rear end inside the pen barrel 1, the rear end of the pen barrel 1 is threadedly connected to a rear cover 3, a plurality of limit grooves 12 are formed on the lower surface of the rear cover 3, an upper cover 2 is slidably sleeved at the front end of the pen barrel 1, a plurality of limit blocks 13 are fixedly installed on the inner bottom wall of the upper cover 2, the inner diameter size of the upper cover 2 matches the outer diameter size of the rear cover 3, the number of the limit grooves 12 is the same as the number of the limit blocks 13 and they correspond one by one. When in use, when the whiteboard pen has no ink and cannot write, by sleeving the upper cover 2 on the rear cover 3, so that the limit blocks 13 can be inserted into the limit grooves 12, thereby temporarily assembling the upper cover 2 and the rear cover 3 together as a whole, that is, the rear cover 3 can be driven to rotate synchronously by twisting the upper cover 2. By using the characteristic that the contact area between the upper cover 2 and the human hand is relatively large, it is convenient for the writing personnel to easily unscrew the rear cover 3 to replace the disposable ink sac 9, and the operation is simple, flexible and very labor-saving.
[0032] In this embodiment, as Figure 5 shown, the pen tip 4 includes a writing tip 401, the outer surface of the writing tip 401 is arranged in a circular arc shape, the rear end of the writing tip 401 is fixedly connected to a middle part 402, and the rear end of the middle part 402 is fixedly connected to an ink absorption end 403. When in use, the circular arc-shaped writing tip 401 makes the pen tip 4 write particularly smoothly, and the ink is absorbed through the ink absorption end 403 and then transmitted to the writing tip 401 through the middle part 402, which is convenient for the writing personnel to write.
[0033] In this embodiment, as Figure 2 and 5As shown, a sealing block 6 is fixedly sleeved inside the pen barrel 1 on the outer surface of the middle part 402. An ink-absorbing sponge 7 is fixedly installed inside the pen barrel 1 on one side of the sealing block 6. One end of the ink-absorbing end 403 penetrates through the sealing block 6 and is inserted into the ink-absorbing sponge 7. A partition 8 is fixedly installed inside the pen barrel 1 on one side of the ink-absorbing sponge 7. A disposable ink sac 9 is slidably inserted on one side of the partition 8. When in use, the ink-absorbing sponge 7 first absorbs the ink inside the disposable ink sac 9 and then transfers the ink to the ink-absorbing end 403, playing a buffering role, which can ensure the ink output volume and avoid the problems of too much ink flowing out sometimes or too little ink resulting in too light handwriting. By setting the sealing block 6, it can prevent ink from overflowing at the connection between the pen barrel 1 and the pen tip 4.
[0034] In this embodiment, as Figure 3 and 5 shown, a fixing groove 20 is formed on the outer surface of the middle part 402. A fixing block 19 is fixedly connected to the inner wall of the pen barrel 1 on the outside of the middle part 402. The fixing block 19 is located inside the fixing groove 20. When in use, through the fixing block 19 and the fixing groove 20, the pen tip 4 can be fixed inside the pen barrel 1 to avoid the pen tip 4 from shaking.
[0035] In this embodiment, as Figure 3 and 5 shown, an annular groove 14 is formed on the outer wall of the pen barrel 1 inside the upper cover 2. An annular convex ring 15 is fixedly connected to the inner wall of the upper cover 2. The annular groove 14 is adapted to the annular convex ring 15.

Anti-slip rubber pads are filled inside the plurality of arc grooves 11. When in use, it increases the friction between the upper cover 2 and the human hand and prevents the phenomenon of slipping when twisting the upper cover 2.
[0037] In this embodiment, as Figure 4As shown in the figure, several abutting blocks 18 are fixedly installed at the top of the rear cover 3. The top of the abutting block 18 abuts against the bottom of the disposable ink sac 9. An internal thread 16 is provided at a position near the rear end on the inner wall of the pen barrel 1, and an external thread 17 adapted to the internal thread 16 is provided on the outer surface of the rear cover 3. During use, the rear cover 3 and the pen barrel 1 can be assembled together through the internal thread 16 and the external thread 17. The disposable ink sac 9 is abutted by the abutting block 18, and the disposable ink sac 9 is limited and fixed inside the pen barrel 1 to prevent the disposable ink sac 9 from shaking inside the pen barrel 1.
[0038] In this embodiment, as Figure 1 shown, a rubber sleeve 10 is fixedly sleeved on the outer surface of the pen barrel 1 near the front end. Anti-slip patterns are provided on the outer surface of the rubber sleeve 10. During use, it is convenient for the writer to hold the pen barrel 1 for writing.
[0039] Working principle: When using a whiteboard pen of the present application, when the whiteboard pen has no ink and cannot write, by sleeving the upper cover 2 on the rear cover 3, the limiting block 13 can be inserted into the limiting groove 12, so that the upper cover 2 and the rear cover 3 are temporarily assembled together as a whole. That is, the rear cover 3 can be driven to rotate synchronously by twisting the upper cover 2. Taking advantage of the fact that the contact area between the upper cover 2 and the human hand is relatively large, it is convenient for the writer to easily unscrew the rear cover 3 to replace the disposable ink sac 9. The operation is simple and flexible, and very labor-saving.
[0040] The foregoing is only the preferred embodiment of the present application and is not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
