[0006] The box body includes a connecting plate, a first clamping plate, and a second clamping plate. The first clamping plate and the second clamping plate are spaced apart from the connecting plate along a second direction. The first clamping plate and the second clamping plate extend in the same direction. The first clamping plate, the second clamping plate, and the connecting plate enclose a receiving cavity. The receiving cavity is used to accommodate at least a portion of the structure of the rubber body. The cavity wall is capable of abutting against the rubber body. An entrance communicating with the receiving cavity is formed between the end of the first clamping plate away from the connecting plate and the end of the second clamping plate away from the connecting plate. The entrance is used for at least a portion of the structure of the rubber body to pass through. A first outlet is formed at one end of the receiving cavity along the first direction. The first outlet is used for the working end to pass through. The first direction and the second direction are perpendicular to each other.

[0007] In one embodiment, the width of the rubber body is defined as W, then: 11mm ≤ W ≤ 13mm.

[0008] In one embodiment, the length of the rubber body is defined as L, then: 88mm≤L≤90mm.

[0009] In one embodiment, the receiving cavity forms a second outlet at the other end along the first direction.

[0010] In one embodiment, the two ends of the rubber body arranged opposite each other along the second direction are a first plane and a second plane, both of which can abut against the cavity wall of the receiving cavity. The two ends of the rubber body arranged opposite each other along the third direction are a first arc surface and a second arc surface, one end of the first plane and one end of the second plane are connected through the first arc surface, and the other end of the first plane and the other end of the second plane are connected through the second arc surface. The first direction, the second direction and the third direction are perpendicular to each other.

[0011] In one embodiment, the first clamping plate includes a first plate body and a first clamping portion connected to each other, and the second clamping plate includes a second plate body and a second clamping portion connected to each other. The end of the first plate body away from the first clamping portion and the end of the second plate body away from the second clamping portion are spaced apart from the connecting plate along a second direction. The first plate body, the first clamping portion, the second plate body, the second clamping portion and the connecting plate enclose a receiving cavity. The first clamping portion extends toward the second clamping portion, and the second clamping portion extends toward the first clamping portion. The entrance is formed between the end of the first clamping portion away from the first plate body and the end of the second clamping portion away from the second plate body.

[0012] In one embodiment, the first plate body near the working end includes a first flat portion and a first arc-shaped transition portion connected to each other, and the first clamping portion near the working end includes a second arc-shaped transition portion. One end of the first flat portion is connected to the connecting plate through the first arc-shaped transition portion, and the other end of the first flat portion is connected to the second arc-shaped transition portion.

[0013] And / or,

[0014] The second plate body includes a second flat portion and a third arc-shaped transition portion connected to each other at one end near the working end. The second clamping portion includes a fourth arc-shaped transition portion at one end near the working end. One end of the second flat portion is connected to the connecting plate through the third arc-shaped transition portion, and the other end of the second flat portion is connected to the fourth arc-shaped transition portion.

[0015] In one embodiment, the length of the box body is less than the length of the rubber body.

[0016] In one embodiment, a gripping portion is provided on the side of the first clamping plate opposite to the second clamping plate.

[0017] In one embodiment, the gripping portion is disposed near the working end.

[0018] In this embodiment of the invention, the first direction is the vertical direction, and the second direction is the front-back direction. The upper end of the eraser body forms the working end, which is used to contact and erase details in the drawing. The thickness of the eraser body refers to its dimension in the front-back direction. The thickness of the eraser body is 1mm ≤ H ≤ 3mm. Compared with the large size design of traditional erasers, this ultra-thin design ensures that the eraser body can easily enter narrow spaces, reducing the contact area between the eraser body and the paper. This allows users to more accurately control the erasing force and range, reducing the risk of accidental erasing due to excessive force. In this embodiment, the thickness H of the eraser body is 2mm. Since the eraser body is relatively thin, it may be difficult for users to directly hold and operate it. Therefore, a matching box is provided, which provides an additional gripping area, allowing users to hold and operate the eraser more easily. The eraser body is used for wiping operations. The housing includes a connecting plate, a first clamping plate, and a second clamping plate. The connecting plate serves as a support structure, connecting the first and second clamping plates together to form a stable frame. The first clamping plate, the second clamping plate, and the connecting plate enclose a receiving cavity that can accommodate at least a portion of the eraser body's structure. The cavity wall can abut against the eraser body, ensuring its stability during use. The inlet allows at least a portion of the eraser body's structure to pass through, facilitating installation and replacement. The first outlet allows the working end of the eraser body to pass through, enabling users to perform wiping operations using the working end. When the working end of the eraser body becomes shorter due to use, the user can adjust the exposed portion of the eraser body through the first outlet to move the unused portion to the working end for continued use, significantly extending the eraser body's service life. This utility model embodiment employs an eraser body with a thickness of 1mm≤H≤3mm. This ultra-thin design allows the eraser body to easily enter confined spaces and perform high-precision erasing operations, making it particularly suitable for detail processing in drawing or design. Furthermore, due to the thinness of the eraser, users can more precisely control the erasing area, avoiding accidental erasing of other parts of the artwork and thus protecting the overall integrity of the work. The use of a first clamping plate and a second clamping plate ensures the stability of the eraser body during use, preventing it from sliding or shifting, thus improving the accuracy and controllability of erasing. The inlet allows for easy installation or replacement of the eraser body, simplifying the operation process and enhancing ease of use. The first outlet allows users to flexibly adjust the exposed length of the eraser as needed, meeting the usage requirements in different scenarios and further enhancing the eraser's flexibility and versatility.

[0029] In the fields of art creation and design, erasers are not merely simple correction tools; they are also important partners for artists to express their creativity and refine their works. However, traditional erasers have some shortcomings in handling drawing details, failing to precisely erase intricate areas.

[0030] After careful research, the applicant found that traditional erasers are usually designed to be large and have a fixed shape, such as the common cuboid or cube-shaped erasers. While this design is suitable for erasing large areas, it is cumbersome and inconvenient when dealing with fine lines and small-area modifications. Furthermore, due to its large contact surface, it is difficult for users to control the erasing area and they are prone to accidentally erasing other parts of the painting, which can affect or damage the entire painting and easily increase unnecessary repair work.

[0031] The main purpose of this invention is to propose an ultra-thin eraser to solve the problem of how to accurately erase detailed parts of a drawing.

[0032] Please see Figure 1 and Figure 2In one embodiment of this utility model, the ultra-thin rubber 100 includes a rubber body 1 and a box body 2. One end of the rubber body 1 along a first direction forms a working end 11. The thickness of the rubber body 1 is defined as H, then: 1mm ≤ H ≤ 3mm. The box body 2 includes a connecting plate 21, a first clamping plate 22, and a second clamping plate 23. The first clamping plate 22 and the second clamping plate 23 are spaced apart from the connecting plate 21 along a second direction. The first clamping plate 22 and the second clamping plate 23 extend in the same direction. The first clamping plate 22, the second clamping plate 23, and the connecting plate... 21 encloses to form a receiving cavity 24, which is used to receive at least a portion of the structure of the rubber body 1. The cavity wall of the receiving cavity 24 can abut against the rubber body 1. An inlet 25 communicating with the receiving cavity 24 is formed between the end of the first clamping plate 22 away from the connecting plate 21 and the end of the second clamping plate 23 away from the connecting plate 21. The inlet 25 is used for at least a portion of the structure of the rubber body 1 to pass through. A first outlet 26 is formed at one end of the receiving cavity 24 along the first direction. The first outlet 26 is used for the working end 11 to pass through. The first direction and the second direction are perpendicular to each other.

[0033] In the embodiments of this utility model, such as Figure 1As shown, the first direction is the up-down direction, and the second direction is the front-back direction. The upper end of the eraser body 1 forms the working end 11, which is used to contact and erase the details in the drawing. The thickness of the eraser body 1 refers to the dimension of the eraser body 1 in the front-back direction. The thickness of the eraser body 1 is 1mm ≤ H ≤ 3mm. Compared with the large size design of traditional erasers, this ultra-thin design ensures that the eraser body 1 can easily enter narrow spaces, reducing the contact area between the eraser body 1 and the paper. This allows the user to more accurately control the erasing force and range, reducing the risk of accidental erasing due to excessive force. In this embodiment, the thickness H of the eraser body 1 is 2mm. At the same time, because the eraser body 1 is relatively thin, it may be difficult for the user to directly hold and operate the eraser body 1. Therefore, a matching box 2 is provided. The box 2 provides an additional gripping area, allowing the user to more easily hold and operate the eraser body 1 for erasing operations. The box 2 includes a connecting plate 21, a second connecting plate 22, and a third connecting plate 23. A clamping plate 22 and a second clamping plate 23, and a connecting plate 21 serve as a support structure, connecting the first clamping plate 22 and the second clamping plate 23 together to form a stable frame. The first clamping plate 22, the second clamping plate 23, and the connecting plate 21 enclose a receiving cavity 24, which can accommodate at least a portion of the structure of the rubber body 1. The cavity wall of the receiving cavity 24 can abut against the rubber body 1, thereby ensuring that the rubber body 1 remains stable during use. The inlet 25 is used for at least a portion of the structure of the rubber body 1 to pass through, facilitating the installation and replacement of the rubber body 1. The first outlet 26 is used for the working end 11 of the rubber body 1 to pass through, making it convenient for users to use the working end 11 of the rubber body 1 for erasing operations. When the working end 11 of the rubber body 1 becomes shorter due to use, the user can adjust the exposed portion of the rubber body 1 through the first outlet 26 to move the unused portion of the rubber body 1 to the working end 11 for continued use, significantly extending the service life of the rubber body 1.

[0034] The technical solution of this utility model adopts an eraser body 1 with a thickness of 1mm≤H≤3mm. This ultra-thin design allows the eraser body 1 to easily enter narrow spaces and complete high-precision erasing operations. It is particularly suitable for detail processing in painting or design. Because the eraser is thin, users can more accurately control the erasing area and avoid accidentally erasing other parts of the artwork, thereby protecting the overall integrity of the work. The use of the first clamping plate 22 and the second clamping plate 23 ensures the stability of the eraser body 1 during use, preventing it from sliding or shifting, and improving the accuracy and controllability of erasing. The use of the inlet 25 allows for easy installation or replacement of the eraser body 1, simplifying the operation process and improving the convenience of use. The use of the first outlet 26 allows users to flexibly adjust the exposed length of the eraser as needed to meet the usage requirements in different scenarios, further enhancing the flexibility and versatility of the eraser.

[0035] Please see Figure 1 In one embodiment, the width of the eraser body 1 is defined as W, which is: 11mm ≤ W ≤ 13mm. Specifically, the width of the eraser body 1 refers to its dimension in the left-right direction. By setting the width of the eraser body 1 to 11mm ≤ W ≤ 13mm, the eraser body 1 is neither too wide, making precise control difficult, nor too narrow, affecting erasing efficiency. This width range ensures that the eraser can meet the needs of detailed erasing and large-area modifications. The moderate width range makes the eraser body 1 easier to hold, allowing users to more intuitively perceive the erasing force and direction, improving the controllability, stability, and accuracy during the erasing process. Compared to traditional wider erasers, this width design allows each part of the eraser body 1 to be fully utilized, reducing waste caused by wear or breakage and improving the utilization rate of the eraser body 1. In addition, in this embodiment, the width W of the eraser body 1 is 12mm.

[0036] Please see Figure 1 In one embodiment, the length of the eraser body 1 is defined as L, which is 88mm ≤ L ≤ 90mm. Specifically, the length of the eraser body 1 refers to its dimensions in the vertical direction. By setting the length of the eraser body 1 to 88mm ≤ L ≤ 90mm, the eraser body 1 is neither too long, making it difficult to handle, nor too short, affecting its efficiency. This reduces the inconvenience of frequently replacing the eraser body 1 due to its shortness. This moderate length makes it easier for users to operate, improving the overall user experience. It also allows the eraser body 1 to be easily placed in a pencil case or tool bag, improving portability. Furthermore, this length range allows the eraser body 1 to be used for large-area corrections, and detailed erasing can be completed by adjusting the exposed length, meeting the needs of different scenarios. In addition, in this embodiment, the length L of the eraser body 1 is 89mm.

[0037] Please see Figure 1In one embodiment, the receiving cavity 24 forms a second outlet 27 at the other end along the first direction. Specifically, the second outlet 27 is located at the lower end of the box body 2, opposite to the first outlet 26, providing a larger operating space for the user to install or replace the rubber body 1. When the user needs to put the rubber body 1 into the receiving cavity 24, the space of the inlet 25 can be expanded by prying open the first clamping plate 22 and the second clamping plate 23. At this time, the existence of the first outlet 26 and the second outlet 27 simultaneously provides operational convenience for prying open the first clamping plate 22 and the second clamping plate 23, making it easier for the rubber body 1 to be put into the receiving cavity 24, thus improving the installation efficiency of the rubber body 1. In addition, when the length of the rubber body 1 is long, part of the rubber body 1 may protrude from the second outlet 27. This design allows the user to choose whether to let the rubber protrude from the second outlet 27 according to the actual length of the rubber body 1, thereby avoiding the problem that the rubber is too long and cannot be fully put into the receiving cavity 24, thus optimizing the flexibility and versatility of the rubber during use.

[0038] Please see Figure 1 and Figure 2 In one embodiment, the two ends of the eraser body 1 arranged opposite each other along the second direction are a first plane 12 and a second plane 13, both of which can abut against the cavity wall of the receiving cavity 24. The two ends of the eraser body 1 arranged opposite each other along the third direction are a first arc surface 14 and a second arc surface 15, one end of the first plane 12 and one end of the second plane 13 are connected by the first arc surface 14, and the other end of the first plane 12 and the other end of the second plane 13 are connected by the second arc surface 15. The first direction, the second direction and the third direction are perpendicular to each other. Specifically, the two ends of the eraser body 1 arranged opposite each other along the front-back direction are a first plane 12 and a second plane 13, which provide stable contact surfaces and can abut against the cavity wall of the receiving cavity 24, ensuring that the eraser body 1 can remain stable during use and preventing the eraser body 1 from moving relative to the box 2 in the vertical direction, thereby improving the controllability, stability and accuracy of the erasing process. Figure 1As shown, the third direction is left and right. The two ends of the eraser body 1, which are set opposite each other in the left and right direction, are the first arc surface 14 and the second arc surface 15, respectively. This makes the edges of the eraser body 1 smoother, reducing the risk of paper scratches or tears caused by sharp edges and helping to protect the overall integrity of the painting, especially when dealing with high-precision paintings or special paper materials. In addition, the eraser body 1 adopts a design that combines arc surfaces and flat surfaces, making it more ergonomic when held, improving the comfort of holding it. Furthermore, since the eraser body 1 has a clear geometric shape and is not a simple rectangle, users can select different contact surfaces to meet different erasing needs in different scenarios. For example, the first flat surface 12 or the second flat surface 13 can be selected for large-area erasing, and the first arc surface 14 or the second arc surface 15 can be selected for detailed processing, thereby achieving a seamless switch from large-area modification to fine line erasing.

[0039] Please see Figure 1 and Figure 3In one embodiment, the first clamping plate 22 includes a first plate body 221 and a first clamping portion 222 connected to each other, and the second clamping plate 23 includes a second plate body 231 and a second clamping portion 232 connected to each other. One end of the first plate body 221 away from the first clamping portion 222 and one end of the second plate body 231 away from the second clamping portion 232 are spaced apart from the connecting plate 21 along a second direction. The first plate body 221, the first clamping portion 222, the second plate body 231, the second clamping portion 232, and the connecting plate 21 enclose a receiving cavity 24. The first clamping portion 222 extends towards the second clamping portion 232, and the second clamping portion 232 extends towards the first clamping portion 222. The end of the first clamping portion 222 away from the first plate body 221 and the end of the second clamping portion 232 away from the second plate body 231 are spaced apart from each other along a second direction. An entrance 25 is formed at one end. Specifically, the first plate body 221 and the second plate body 231 are spaced apart by the connecting plate 21 to form a stable support structure, ensuring that the eraser body 1 will not shift or slide during use, allowing the user to more accurately control the erasing area and avoid accidentally erasing other parts. The first clamping part 222 and the second clamping part 232 both extend inward to form a contracted entrance 25, which significantly enhances the clamping force on the eraser body 1. This design effectively prevents the eraser body 1 from sliding out of the entrance 25 during use, improving the reliability of use. When the user needs to put the eraser body 1 into the receiving cavity 24, the space of the entrance 25 can be expanded by prying open the first clamping part 222 and the second clamping part 232, so that the eraser body 1 can be easily put into the receiving cavity 24 without sliding out. In this embodiment, the shapes of the first clamping part 222 and the second clamping part 232 can match the shape of the first arc surface 14, so that the first clamping part 222 and the second clamping part 232 can abut against the first arc surface 14, thereby increasing the friction between the rubber body 1 and the box body 2 and improving the stability of the rubber body 1.

[0040] According to another embodiment of the present invention, the first clamping plate 22 and the second clamping plate 23 both extend in the left-right direction, so that the first clamping plate 22 and the second clamping plate 23 can respectively abut against the first plane 12 and the second plane 13 of the rubber body 1, so that the rubber body 1 can be installed more stably.

[0041] Please see Figure 1 and Figure 3In one embodiment, the first plate body 221 near the working end 11 includes a first flat portion 2211 and a first arcuate transition portion 2212 connected to each other; the first clamping portion 222 near the working end 11 includes a second arcuate transition portion 2221; one end of the first flat portion 2211 is connected to the connecting plate 21 through the first arcuate transition portion 2212; and the other end of the first flat portion 2211 is connected to the second arcuate transition portion 2221; and / or, the second plate body 231 near the working end 11 includes a second flat portion 23 connected to each other. The second clamping part 232 includes a fourth arc-shaped transition part 2321 at one end near the working end 11, and one end of the second flat part 2311 is connected to the connecting plate 21 through the third arc-shaped transition part 2312. The other end of the second flat part 2311 is connected to the fourth arc-shaped transition part 2321. Specifically, the first flat part 2211 and the second flat part 2311 provide relatively flat working surfaces, allowing the user to more accurately control the force and direction during the erasing operation, thereby improving the erasing accuracy. The first arc-shaped transition section 2212, the second arc-shaped transition section 2221, the third arc-shaped transition section 2312, and the fourth arc-shaped transition section 2321 form rounded corners on both sides of the upper end of the box body 2, further enhancing the roundness and smoothness of the box body 2. Furthermore, the first arc-shaped transition section 2212, the second arc-shaped transition section 2221, the third arc-shaped transition section 2312, and the fourth arc-shaped transition section 2321 are all located close to the working end 11 of the eraser body 1, which can prevent the sharp edges of the box body 2 from causing damage to the user's hands or paper, further improving the accuracy and comfort of operation. Appropriate; in addition, in this embodiment, depending on actual usage requirements, only the first flat portion 2211, the first arc-shaped transition portion 2212 and the second arc-shaped transition portion 2221 can be selected, or only the second flat portion 2311, the third arc-shaped transition portion 2312 and the fourth arc-shaped transition portion 2321 can be selected, or the first flat portion 2211, the second flat portion 2311, the first arc-shaped transition portion 2212, the second arc-shaped transition portion 2221, the third arc-shaped transition portion 2312 and the fourth arc-shaped transition portion 2321 can be selected simultaneously. This embodiment does not limit this.

[0042] Please see Figure 1In one embodiment, the length of the box body 2 is less than the length of the rubber body 1. Specifically, since the length of the box body 2 is less than the length of the rubber body 1, it is ensured that the working end 11 of the rubber body 1 can extend from the first outlet 26 of the box body 2. This allows the user to adjust the extension length from the first outlet 26 without completely removing the rubber body 1, simplifying the operation process and improving the convenience of use. For example, when making large-area modifications or when the working end 11 of the rubber body 1 becomes shorter due to use, the user can adjust the exposed part of the rubber body 1 through the first outlet 26 to move the unused part of the rubber body 1 to the working end 11 for continued use to improve efficiency.

[0043] Please see Figure 1 and Figure 2 In one embodiment, a grip portion 2313 is provided on the side of the first clamping plate 22 opposite to the second clamping plate 23. Specifically, the design of the grip portion 2313 fully considers ergonomic principles, making it more in line with the curve of the user's hand when holding the eraser box 2. The user can easily adjust and use the eraser with one hand, reducing fatigue caused by prolonged use. The grip portion 2313 provides the user with a clear grip area, avoiding inconvenience caused by improper grip. Especially when fine erasing is required, this design significantly improves the accuracy of operation. The grip portion 2313 can be designed with anti-slip texture or grooves to enhance the friction when gripping and prevent the box 2 from slipping from the hand. Furthermore, the grip portion 2313 can also be enhanced with different colors, materials, or textures to improve the visual effect, improving the product's appearance design while maintaining functionality, making it more attractive.

[0044] Please see Figure 1 and Figure 2 In one embodiment, the grip portion 2313 is disposed near the working end 11. Specifically, the grip portion 2313 is disposed near the working end 11 of the eraser body 1, i.e. the end used for erasing. This means that the user's grip point can be closer to the actual working area, thereby obtaining better control. This is especially important for tasks that require high-precision operation, allowing the user to control the operation of the eraser body 1 more directly when performing fine erasing, reducing the risk of accidentally erasing other parts, protecting the overall integrity of the work, and the grip point being close to the working end 11 can reduce the influence of torque, making the user apply force more evenly and stably, avoiding accidental erasing or eraser displacement due to excessive torque, and improving the accuracy and controllability of erasing.

[0045] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
