[0001] This utility model relates to the field of PVC flooring construction technology, and more specifically, to a cutting device for the inside corner of PVC flooring. Background Technology

[0002] Cutting and installing the inner corner where the floor meets the wall is a major challenge during PVC flooring installation. Traditional methods struggle to ensure precise finishing in this area, affecting the overall aesthetics and quality. This specialized tool was developed to solve this problem; it's specifically designed for the cutting and installation of PVC flooring at inner corners. With this tool, installers can accurately measure the corner dimensions and cut according to precise data, ensuring a perfect fit between the flooring and the wall at the inner corner.

[0003] Among the existing publicly available documents, patent publication number CN204414225U discloses a PVC sheet cutting device. This technology prevents the cutting head from overheating by rotating the turntable after the cutting head has been cutting the PVC sheet for a period of time, thus effectively protecting the cutting head, extending its service life, and reducing production costs. However, this technology still has the following problems.

[0004] When cutting the inside corner of PVC flooring, the roller and the cutter need to work together. However, when the roller is pressing, it is difficult to self-scrape the surface of the PVC flooring, which makes the roller pressing creases easily blocked by impurities and the shearing is prone to deviation. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a cutting device for the inside corner of PVC flooring, comprising a holding rod, a sleeve fixedly connected to the bottom end of the holding rod, a conical roller rotatably mounted on the inner wall of the sleeve, the conical roller being used to press the inside corner of the PVC flooring to form a cutting line, and a floating cleaning mechanism provided on the upper surface of the sleeve near its edge line, the floating cleaning mechanism comprising: A sleeve rod is attached to the upper surface of the sleeve strip and near its edge line, and a linkage block is fixed to the lower surface of the sleeve rod and near one end of it; An arc-shaped scraper is fixedly connected to the bottom of the linkage block. The arc-shaped scraper is used to scrape away impurities from the inside corners of the PVC floor. The guide rod slides on the inner wall of the sleeve rod. The bottom end of the guide rod is fixedly connected to the sleeve strip. The top end of the guide rod is fixed with a limit block. A rubber sleeve is fixed between the limit block and the sleeve rod.

[0006] In a preferred embodiment, the sleeve rod and the sleeve bar are arranged perpendicularly, and the inner wall of the sleeve rod and the outer wall of the guide rod are both smooth surfaces.

[0007] In a preferred embodiment, the rubber sleeve is made of rubber, and the cross-sectional area of ​​the limiting block is larger than the cross-sectional area of ​​the guide rod.

[0008] In a preferred embodiment, the vertical cross-sectional shape of the arc-shaped scraper is arc-shaped, and there is an included angle between the arc-shaped scraper and the linkage block.

[0009] In a preferred embodiment, side scraper strips are fixed at both ends of the arc-shaped scraper, and the two side scraper strips are symmetrically arranged about the arc-shaped scraper.

[0010] In a preferred embodiment, a slanted rod is fixed to one side of the outer wall of the gripping rod, and an inclined frame is fixed to the bottom end of the slanted rod. An inclined blade is slidably installed on the inner wall of the inclined frame. The inclined blade is used to cut the inside corner of the PVC floor. A sleeve block is fixed to one side of the inclined frame, and a bolt is threaded onto the inner wall of the sleeve block, and the bolt is used to press the inclined blade.

[0011] In a preferred embodiment, the top cross-sectional area of ​​the beveled blade is larger than the bottom cross-sectional area, and the beveled blade is inclined.

[0012] The technical effects and advantages of this utility model are as follows: 1. This utility model adopts a floating cleaning mechanism. The sleeve rod drives the linkage block to move to the right, and the arc-shaped scraper scrapes along the inside corner of the PVC floor to remove impurities. The guide rod supports the limiting block, and the limiting block limits the rubber sleeve. The rubber sleeve elastically compresses the upper surface of the sleeve rod, and the sleeve rod can float along the outer wall of the guide rod. Thus, the arc-shaped scraper can float to remove impurities from the inside corner of the PVC floor, ensuring that the inside corner of the PVC floor can be rolled without impurities to form a cutting line, and achieving stable and anti-deviation cutting.

[0013] 2. In this utility model, the oblique blade moves downward along the inner wall of the oblique frame at an angle. After the oblique blade position is slightly adjusted, the bolt is pressed onto the oblique blade, which firmly fixes the oblique blade to the inner wall of the oblique frame. This achieves adjustable locking of the oblique blade's tilt position. The oblique rod drives the oblique frame so that the oblique blade performs cutting operations along the cutting line pressed by the conical roller. The oblique blade can be inserted and cut in an adjustable tilt. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 - Figure 4 The device shown is a cutting device for the inside corner of PVC flooring. The device is equipped with a floating cleaning mechanism. The floating cleaning mechanism enables the arc scraper to float and remove impurities from the inside corner of the PVC flooring, ensuring that the inside corner of the PVC flooring can be rolled without impurities to form a cutting line, and achieving stable and anti-deviation cutting. The specific structure of the floating cleaning mechanism is as follows.

[0021] In this embodiment, as Figure 1 - Figure 3 As shown, a sleeve 2 is fixedly connected to the bottom end of the gripping rod 1. A conical roller 3 is rotatably mounted on the inner wall of the sleeve 2. The conical roller 3 is used to press the inside corner of the PVC floor to form a cutting line. A floating cleaning mechanism is provided on the upper surface of the sleeve 2 near its edge line. The floating cleaning mechanism includes: a sleeve 4, which fits against the upper surface of the sleeve 2 near its edge line; a linkage block 5 is fixed to the lower surface of the sleeve 4 near one end; an arc-shaped scraper 6, which is fixedly connected to the bottom end of the linkage block 5 and is used to scrape away impurities in the inside corner of the PVC floor; and a guide rod 7, which slides on the inner wall of the sleeve 4. The bottom end of the guide rod 7 is fixedly connected to the sleeve 2, and a limit block 8 is fixed to the top end of the guide rod 7. A rubber sleeve 9 is fixed between the limit block 8 and the sleeve 4. The sleeve 4 and the sleeve 2 are arranged perpendicularly. The inner wall of the sleeve 4 and the outer wall of the guide rod 7 are both smooth surfaces. The rubber sleeve 9 is made of rubber, and the cross-sectional area of ​​the limit block 8 is larger than the cross-sectional area of ​​the guide rod 7. The vertical cross-section of the arc-shaped scraper 6 is arc-shaped, and there is an angle between the arc-shaped scraper 6 and the linkage block 5.

[0022] In this embodiment, as Figure 2As shown, side scraper strips 10 are fixed to both ends of the arc-shaped scraper 6, and the two side scraper strips 10 are symmetrically arranged about the arc-shaped scraper 6. The arc-shaped scraper 6 and the side scraper strips 10 can float and remove impurities from the inside corners of PVC flooring, achieving coordinated impurity removal.

[0023] This technology is used for a cutting device for the inside corner of PVC flooring. When in use, the hand holds the gripping rod 1 and pushes it to move. The gripping rod 1 moves the sleeve 2, which in turn moves the guide rod 7 to the right. The guide rod 7 moves the sleeve 4 to the right, which in turn moves the linkage block 5 to the right. The linkage block 5 moves the arc-shaped scraper 6 to the right. The arc-shaped scraper 6 scrapes along the inside corner of the PVC flooring to remove impurities. Simultaneously, the arc-shaped scraper 6 moves the two side scraper strips 10 to the right, which also scrape along the inside corner of the PVC flooring to remove impurities. The sleeve 2 supports the guide rod 7, which in turn supports the limiting block 8. The limiting block 8 limits the rubber sleeve 9, which elastically compresses the upper surface of the sleeve 4. This allows the sleeve 4 to float along the outer wall of the guide rod 7, enabling the arc-shaped scraper 6 and the side scraper strips 10 to float and remove impurities from the inside corner of the PVC flooring. At the same time, the sleeve 2 moves the conical roller 3 to the right, which presses against the inside corner of the PVC flooring to form a cutting line.

[0024] In this embodiment, as Figure 1 - Figure 4 As shown, a diagonal bar 11 is fixed to one side of the outer wall of the gripping rod 1. An inclined frame 12 is fixed to the bottom end of the diagonal bar 11, and a diagonal blade 13 is slidably installed on the inner wall of the inclined frame 12. The diagonal blade 13 is used for cutting the inside corner of PVC flooring. A sleeve block 14 is fixed to one side of the inclined frame 12. A bolt 15 is threaded onto the inner wall of the sleeve block 14, and the bolt 15 is used to press the diagonal blade 13. The cross-sectional area of ​​the top end of the diagonal blade 13 is larger than the cross-sectional area of ​​its bottom end, and the diagonal blade 13 is inclined.

[0025] This technology is used for a cutting device for the inside corners of PVC flooring. In use, by tilting and moving the oblique blade 13 downward, the oblique blade 13 moves downward along the inner wall of the oblique frame 12. After the oblique blade 13 is finely adjusted, the bolt 15 is rotated. The bolt 15 engages with the sleeve block 14, and the bolt 15 presses against the oblique blade 13, firmly fixing the oblique blade 13 to the inner wall of the oblique frame 12. This achieves adjustable locking of the oblique blade 13's tilt position. Then, by moving the holding rod 1, the oblique rod 11 moves, and the oblique rod 11 moves the oblique frame 12, causing the oblique blade 13 to perform the cutting operation along the cutting line pressed by the conical roller 3.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
