[0027] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0028] The present invention discloses a multi-color thermal pen with an erasable pen head. Figure 1-5 As shown, the multi-color thermal pen with an erasable pen tip comprises a pen tube 1, a pen tip tube 2 and an erasable rubber sleeve 3, wherein the pen tip tube 2 is connected to the pen tube 1, and the pen tip tube 2 comprises a threaded tube portion, a mounting tube portion 21 and a tapered tube portion 22, one end of the pen tube 1 is provided with a thread, and the pen tip tube 2 is detachably connected to the pen tube 1 through the threaded tube portion.

[0029] The erasable rubber sleeve 3 is detachably mounted on the pen tip tube 2, and the erasable rubber sleeve 3 includes a first sleeve portion 31 and a second tapered sleeve portion 32 that are integrally connected. The first sleeve portion 31 is mounted on the mounting tube portion 21, and the second tapered sleeve portion 32 is mounted on the tapered tube portion 22, so that the writing brush can be wiped by the first sleeve portion 31 or the second tapered sleeve portion 32. In addition, a connection structure is provided between the first sleeve portion 31 and the mounting tube portion 21, so that the erasable rubber sleeve 3 is fixed to the pen tip tube 2.

[0030] By setting the above structure, the erasable rubber sleeve 3 can be stably installed on the pen head tube 2 by using the connection structure, so that when writing with the thermal pen and a writing error occurs, the user can directly tilt the thermal pen to use the erasable rubber on the thermal pen head tube 2 to wipe off the erroneous traces, which is more convenient to use and faster to wipe, thereby improving the efficiency of the user in writing and handling erroneous traces. At the same time, after the erasable rubber sleeve 3 is installed on the pen head tube 2, the loss of the erasable rubber can be further avoided, and when the erasable rubber on the thermal pen needs to be replaced, it can be directly removed and replaced, thereby increasing the frequency of use of this thermal pen.

[0031] It should be noted that the erasable rubber sleeve 3 is made of the material of existing erasable rubbers, has a certain elasticity, and can wipe off the traces written by the thermal pen.

[0032] In some embodiments, Figure 3 , Figure 4 and Figure 5 As shown, the above-mentioned connection structure includes an external thread 41 arranged at the center position of the outer wall of the mounting tube portion 21, and an internal thread is arranged at the center position of the inner wall of the first sleeve portion 31. After the first sleeve portion 31 is sleeved onto the mounting tube portion 21, the internal thread 42 on the first sleeve portion 31 is matched and connected with the external thread 41 on the mounting tube portion 21.

[0033] In this way, after the first sleeve portion 31 is mounted on the mounting tube portion 21 and they are connected to each other, the erasable rubber sleeve 3 can be stably fixed to the pen head tube 2, and when it is subsequently disassembled, the erasable rubber sleeve 3 can be disassembled by simply rotating it in the opposite direction. In addition, when using the erasable rubber sleeve 3 for wiping, the erasable rubber sleeve 3 is not likely to be displaced or fall off.

[0034] Further, such as Figure 3 , Figure 4 and Figure 5 As shown, a plurality of annular grooves 52 are provided at one end of the mounting tube portion 21 away from the conical tube portion 22, and a plurality of annular strips 51 are provided at one end of the inner wall of the first sleeve portion 31 away from the second conical sleeve portion 32. After the first sleeve portion 31 is sleeved onto the mounting tube portion 21, the plurality of annular strips 51 are respectively snapped into each annular groove 52.

[0035] By utilizing the structure of the annular strip 51 , the connection between the first sleeve portion 31 and the mounting tube portion 21 can be made more stable, so that the first sleeve portion 31 is not easily dropped from the mounting tube portion 21 , thereby improving the connection stability.

[0036] Among them, Figure 3As shown, the side of each annular strip 51 away from the tapered tube portion 22 is in an inclined shape.

[0037] By setting the side of the annular strip 51 to be in an inclined shape, the annular strip 51 will not be greatly interfered by the annular groove 52 when the first sleeve portion 31 is installed. At the same time, after the installation is completed, the annular strip 51 can be better snapped into the annular groove 52.

[0038] In some embodiments, Figure 3 , Figure 4 and Figure 5 As shown, a plurality of annular protrusions 61 are evenly arranged on the inner wall of the second cone sleeve portion 32, and a plurality of annular embedding grooves 62 are evenly arranged on the outer wall of the cone tube portion 22. After the second cone sleeve portion 32 is sleeved onto the cone tube portion 22, each annular protrusion 61 is respectively embedded in each embedding groove 62.

[0039] By setting such a structure, the second cone sleeve portion 32 can be better fitted and fixed to the cone tube portion 22. At the same time, when the thermal pen is tilted and the rubber sleeve 3 is used for wiping, due to the setting of the annular protrusion 61 and the embedding groove 62, the position of the second cone sleeve portion 32 is not easily shifted, and the second cone sleeve portion 32 is not easily softened and folded.

[0040] In some embodiments, Figure 1 and Figure 5 As shown, a limiting ring piece 7 is fixedly provided at the end of the tapered tube portion 22 . After the second tapered sleeve portion 32 is sleeved onto the tapered tube portion 22 , the end of the second tapered sleeve portion 32 abuts against the limiting ring piece 7 .

[0041] By setting the limiting ring piece 7, a limit can be formed for the second cone sleeve portion 32 to reduce the possibility of its falling off. At the same time, the end edge of the second cone sleeve portion 32 can be relatively closed by using this limiting ring piece 7 to prevent the user from flipping the edge of the second cone sleeve portion 32 for a long time and causing the position to be turned over.

[0042] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0043] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0044] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
