Detailed Description of Embodiments

[0028] Multiple preferred embodiments of this application will be introduced below with reference to the accompanying drawings, so as to make its technical content clearer and easier to understand. This application may be embodied through many different forms of embodiments. the scope of protection of this application is not limited to the embodiments mentioned herein.

[0029] In the accompanying drawings, components with the same structure are labeled with the same numbers, and components with similar structures or functions are labeled with similar numbers. The size and thickness of each component shown in the accompanying drawings are arbitrary. This application does not limit the size and thickness of each component. In order to make the illustration clearer, the thickness of some components in the accompanying drawings has been appropriately exaggerated.

[0030] As shown in Fig. 1, Fig. 13 and Fig. 24, this application further provides a ceramic tile leveling device 10, comprising a first component 100 and a second component 200. The first component 100 comprises a base 110 and a supporting portion 120 vertically extending upwards from the base 110, wherein a joint between the supporting portion 120 and the base 110 is arranged as a tearable portion 124, which can achieve the separation of the supporting portion 120 from the base 110; a lower portion of the supporting portion 120 is configured to be sheet-shaped, and an upper portion is configured to be rod-shaped. When in use, the first component 100 is placed between at least two adjacent ceramic tiles 20, wherein the base 110 is located below the ceramic tiles 20, the lower portion of the supporting portion 120 is located in a gap 21 between the ceramic tiles 20, and the upper portion of the supporting portion 120 protrudes from upper surfaces of the ceramic tiles 20.

[0031] The second component 200 is used for fixing the first component 100 between the ceramic tiles. The second component 200 comprises a cylindrical channel 201 for receiving a rod-shaped portion 122 of the supporting portion 120. When in use, the cylindrical channel 201 of the second component 200 is sleeved on an outer side of the rod-shaped portion 122, and the second component 200 may rotate relative to the rod-shaped portion 122. A bottom 220 of the second component 200 may be used for contacting the upper surfaces of the ceramic tiles 20. The second component 200 may rotate and move upwards and downwards along the supporting portion 120. When the second component 200 rotates and moves downwards along the supporting portion 120, the bottom 220 of the second component 200 is pressed against the upper surfaces of the ceramic tiles 20, thus fixing the first component 100 between the ceramic tiles 20. The bottom 220 of the second component 200 is provided with a third component 300. When the second component 200 rotates downwards along the supporting portion 120, the third component 300 first contacts the surfaces of the ceramic tiles 20, then the second component 200 continues to move towards the ceramic tiles 20, and the third component 300 is fixed on the upper surfaces of the ceramic tiles 20. At this time, the second component 200 continues to rotate, and the third component 300 no longer rotates with the second component 200, but is fixed on the upper surfaces of the ceramic tiles 20, so that the ceramic tiles 20 can be prevented from rotating with the second component 200, thus preventing the ceramic tiles 20 from moving and being misaligned.

[0032] In the existing technology, after the second component rotates downwards along the supporting portion and the second component contacts the upper surfaces of the ceramic tiles, in order to fix the first component as much as possible, the second component still needs to be rotated. At this time, since the second component has already been in contact with the ceramic tiles, pressure will be generated between the second component and the ceramic tiles. Continuing to rotate the second component may cause the ceramic tiles to move or be misaligned, resulting in uneven spacing between the ceramic tiles. However, by using the ceramic tile leveling device 10 provided in this application, the third component 300 is fixed on the upper surfaces of the ceramic tiles 20, so that the ceramic tiles 20 can be prevented from moving or being misaligned due to the rotation with the second component 200, thus making the spacing between the ceramic tiles 20 more even.

[0033] The ceramic tile leveling device 10 in this application will be described below through multiple embodiments.Embodiment 1

[0034] Fig. 1 to Fig. 15 show embodiment 1. As shown in Fig. 4, the first component 100 is provided with a base 110, and a supporting portion 120 is formed by vertically protruding upwards from the base 110, wherein a lower portion of the supporting portion 120 is sheet-shaped, the end of the sheet-shaped portion 121 (the end portion away from the base 110) is approximately conical, an upper portion of the supporting portion 120 is rod-shaped, and the end of the rod-shaped portion 122 is connected to the conical end of the sheet-shaped portion 121. The rod-shaped portion 122 is provided with a thread 123. A joint between the supporting portion 120 and the base 110 is arranged as a tearable portion 124, which can achieve the separation of the supporting portion 120 from the base 110. In some implementations, the thickness of the tearable portion 124 is reduced compared with the sheet-shaped portion 121 of the supporting portion 120, making it easier to tear. In some other implementations, as shown in Fig. 5, the width of the tearable portion 124 is reduced compared with the sheet-shaped portion 121 of the supporting portion 120. At the same time, the tearable portion 124 is provided with a plurality of slot holes 125 that run through along the thickness direction of the sheet-shaped portion 121.

[0035] As shown in Fig. 5 and Fig. 6, an upper surface 111 of the base 110 is used for contacting the lower surfaces of the ceramic tiles 20, and the upper surface 111 of the base 110 is approximately a flat surface. The thickness h of the base 110 decreases from the middle to two ends of the base 110, and the width x of the base 110 also decreases from the middle to two ends of the base 110. The two ends of the base 110 are respectively provided with grooves 112. The grooves 112 run through the base 110 along the thickness direction of the base 110.

[0036] It should be understood that the structure of the first component 100 is not limited to this embodiment, and other structures comprising the threaded rod-shaped portion 122 may be applied to this application. Preferably, the first component 100 is manufactured through integral molding.

[0037] As shown in Fig. 7, a central portion of the second component 200 is provided with a cylindrical channel 201, and the cylindrical channel 201 is used for receiving the rod-shaped portion 122 of the supporting portion 120. A side wall of the cylindrical channel 201 is provided with a thread engaged with the rod-shaped portion 122. The bottom 220 of the second component 200 will contact the upper surfaces of the ceramic tiles. When the second component 200 rotates along the supporting portion 120 towards the ceramic tiles 20, the bottom 220 of the second component 200 contacts the upper surfaces of the ceramic tiles 20, and as the second component 200 rotates, the first component 100 is fixed between the ceramic tiles 20. The shape of the second component 200 does not constitute a limitation on this application. For example, the second component 200 may be square, cylindrical, or in other shapes. As long as the inside of the second component 200 is provided with a cylindrical channel 201 coupled with the rod-shaped portion 122 of the supporting portion 120, the function of fixing the first component 100 by using the second component 200 can be achieved.

[0038] In this embodiment, as shown in Fig. 8, the second component 200 comprises a head 210 provided with a cylindrical channel 201, a bottom 220 provided with a circular flange 221, and a side wall 230 extending from the head 210 to the bottom 220. The insides of the side wall 230 and the bottom 220 are configured to be hollow, thus forming a cavity 231. The cavity 231 is communicated with the cylindrical channel 201 and runs through the entire second component 200.

[0039] The side wall 230 comprises a cylindrical portion 232 in a center and ribs 233 located on a side surface of the cylindrical portion 232, wherein the number of the ribs 233 may be two or more, which are uniformly distributed around the cylindrical portion 232. For example, Fig. 7 shows two ribs 233, and Fig. 15 shows three ribs 233.

[0040] As shown in Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12 and Fig. 15, one side of the circular flange 221 facing towards the ceramic tiles is provided with a third component 300. When the second component 200 rotates along the supporting portion 120 to move towards the ceramic tiles 20, the third component 300 first contacts the surfaces of the ceramic tiles 20, and then the third component 300 no longer rotates with the second component 200. In this way, the second component 200 continues to rotate to fix the first component 100, and the ceramic tiles 20 will not be deviated or misaligned under the fixing effect of the third component 300, thus helping to keep the gap between the ceramic tiles 20 more even. In this embodiment, the third component 300 is a ring-shaped component arranged in the circular flange 221. Specifically, as shown in the figures, the bottom 220 of the second component 200 is provided with at least one arc-shaped limiting portion 222, and the curvature of the limiting portion 222 matches the curvature of the flange 221, that is, the limiting portion 222 is approximately parallel to the flange 221, thus forming a groove 223 between the limiting portion 222 and a side wall of the flange 221. The ring-shaped component is mounted in the groove 223. At the same time, a first protrusion 301 is formed on the ring-shaped component towards the limiting portion 222, a second protrusion 2221 is formed on the limiting portion 222 towards the flange 221, and the first protrusion 301 is clamped on the second protrusion 2221. In this way, the limiting portion 222 connects the ring-shaped component to the flange 221, but the limiting portion 222 does not restrict the degree of freedom of the third component 300 along the circumferential direction of the flange 221. When the third component 300 contacts the surfaces of the ceramic tiles, the second component 200 rotates, while the third component 300 no longer rotates. In some implementations, as shown in the figures, the groove 223 may run through to the upper surface of the flange 221.

[0041] The number of the limiting portions 222 may be set according to the actual needs. For example, Fig. 12 shows two limiting portions 222 and the two limiting portions are symmetrically arranged; Fig. 14 shows three limiting portions 222, which are uniformly arranged along the circumferential direction of the flange 221.

[0042] A process of using the ceramic tile leveling device 10 in this embodiment is as follows: the first component 100 is placed between adjacent ceramic tiles 20, wherein the base 110 is located below the ceramic tiles, the sheet-shaped portion 121 of the supporting portion 120 is located in a gap between the ceramic tiles 20, and the rod-shaped portion 122 of the supporting portion 120 protrudes out of the ceramic tiles 20; the cylindrical channel 201 of the second component 200 is engaged with the rod-shaped portion 122, the second component 200 is rotated so that the second component 200 moves towards the ceramic tiles 20; after the second component 200 moves a certain distance, the third component 300 first contacts the upper surfaces of the ceramic tiles 20, the second component 200 is continuously rotated, the third component 300 is fixed on the upper surfaces of the ceramic tiles 20 and does not rotate with the second component 200 of the second component 200; at this time, as the second component 200 continues to rotate, the ceramic tiles 20 will not be deviated or moved, thus ensuring the evenness of the gap 21 between the ceramic tiles 20.Embodiment 2

[0043] Fig. 16 to Fig. 18 show embodiment 2. In this embodiment, the first component 100 is the same as that in embodiment 1, which will not be repeated here.

[0044] The difference between the second component 200 in this embodiment and the second component 200 in embodiment 1 is that the third component 300 is fixed on the second component 200 in a different way.

[0045] As shown in Fig.17 and Fig. 18, the bottom 220 of the second component 200 is cylindrical and provided with a side wall 240 along the vertical direction; the third component 300 is a ring-shaped component with a U-shaped cross section, and the side wall of the bottom 220 of the second component 200 is accommodated in a U-shaped groove 301 of the ring-shaped component.

[0046] The surface of the side wall 240 of the bottom 220 is provided with a groove 241 arranged along the circumferential direction. An end portion of one side wall of the third component 300 is provided with a protrusion 311 extending towards the second component 200. When the third component 300 accommodates the bottom 220, the protrusion 311 falls into the groove 241, thus connecting the third component 300 to the second component 200. The groove 241 may be provided in the inner surface of the bottom 220, or as shown in the figure, provided in the outer surface of the bottom 220. Accordingly, it can be seen that the groove 241 provided in the side wall 240 of the bottom 220 forms a limiting portion, thus connecting the third component 300 to the second component 200. The groove 241 does not restrict the degree of freedom of the third component 300 along the circumferential direction of the second component 200, that is, the second component 200 can rotate relative to the third component 300.

[0047] The other structures of the second component 200 in this embodiment, such as the cylindrical channel 201, the side wall 230 connecting the head 210 and the bottom 220, and the cavity 231 in the side wall 230, are the same as those in embodiment 1.

[0048] When the ceramic tile leveling device 10 in this embodiment is in use, and when the second component 200 rotates to move downwards along the supporting portion 120, the third component 300 first contacts the upper surfaces of the ceramic tiles 20. When the second component 200 is continuously rotated, the third component 300 can be fixed on the surfaces of the ceramic tiles 20 to prevent the ceramic tiles 20 from being deviated with the rotation of the second component 200.Embodiment 3

[0049] Fig. 19 to Fig. 21 show embodiment 3. In this embodiment, the first component 100 is the same as that in embodiment 1, which will not be repeated here.

[0050] The difference between the second component 200 in this embodiment and the second component 200 in embodiment 1 is that the third component 300 is fixed on the second component 200 in a different way.

[0051] As shown in Fig. 20 and Fig. 21, the bottom 220 of the second component 200 is cylindrical and has a side wall along the vertical direction. The third component 300 is a ring-shaped component mounted on the inner side of the bottom 220, and the bottom end of the third component 300 protrudes out of the bottom 220 of the second component 200. The outer side of the side wall of the bottom 220 is provided with at least one first groove 251 along the circumferential direction. A through hole 252 is formed in the bottom 220 of the first groove 251. The position of the third component 300 corresponding to the first groove 251 is provided with a second groove 320 arranged along a circumferential direction. An arc-shaped component 260 is accommodated in the first groove 251. The inner side of the arc-shaped component 260 is provided with a protruding portion 261. The protruding portion 261 passes through the through hole 252 of the first groove 251 and enters the second groove 320 of the third component 300. In this way, the third component 300 is connected to the second component 200 through the arc-shaped component 260. It should be understood that the number of the first grooves 251 may be set according to the actual needs. For example, the number of the first groove 251 may be one, that is, the first groove 251 forms a circular ring on the side wall of the bottom 220. Alternatively, as shown in the figures, the number of the first grooves 251 is two, which are arranged symmetrically. Alternatively, the number of the first grooves 251 may be multiple, which are uniformly arranged along the circumferential direction of the side wall. It should also be understood that the number of the through holes 252 in the bottom 220 of the first groove 251 may be multiple, that is, a plurality of through holes 252 may be provided in the bottom 220 of one first groove 251. Correspondingly, the number of the protruding portions 261 of the arc-shaped component 260 matches the number of the through holes 252. Through the cooperation between the second groove 320 of the third component 300 and the protruding portion 261 of the arc-shaped component 260, the degree of freedom of the third component 300 along the circumferential direction of the second component 200 is not restricted, and the second component 200 can rotate relative to the third component 300.

[0052] When the ceramic tile leveling device 10 in this embodiment is in use, and when the second component 200 rotates to move downwards along the supporting portion 120, the bottom end of the third component 300 protrudes out of the bottom 220 of the second component 200, so that the third component 300 first contacts the upper surfaces of the ceramic tiles. When the second component 200 is continuously rotated, the third component 300 can be fixed on the surfaces of the ceramic tiles to prevent the ceramic tiles from being deviated with the rotation of the second component 200.Embodiment 4

[0053] Fig. 22 to Fig. 23 show embodiment 4. In this embodiment, the first component 100 is the same as that in embodiment 1, which will not be repeated here.

[0054] The difference between the second component 200 and the second component 200 in embodiment 1 is that the structure of the third component 300 and the way it is fixed on the second component 200 are different.

[0055] As shown in the figures, the bottom 220 of the second component 200 is connected to a connecting member 270, the shape of the connecting member 270 matches the shape of the bottom 220, and it is arranged on the surface of the bottom 220 facing towards the ceramic tiles. The surface of the bottom 220 facing towards the connecting member 270 is provided with a plurality of positioning grooves 271, and positions on the connecting member 270 corresponding to the positioning grooves 271 are provided with through holes 272. The third component 300 is composed of balls, each ball is arranged in the positioning groove 271, and portions of the balls pass through the through holes 272 of the connecting members 270, so that portions of the balls protrude out of the second component 200. Preferably, the plurality of positioning grooves 271 are uniformly arranged along the circumferential direction, so that a plurality of balls are uniformly distributed at the bottom 220. In this embodiment, the third component 300 is composed of balls, and the connecting member 270 forms a limiting portion to connect the balls to the second component 200. After the balls contact the surfaces of the ceramic tiles 20, the second component 200 continues to rotate, and the balls will roll in place, that is, the positions of the balls relative to the ceramic tiles do not change, and the second component 200 rotates relative to the balls, thus preventing the ceramic tiles from being deviated.

[0056] When the ceramic tile leveling device 10 in this embodiment is in use, and when the second component 200 rotates to move downwards along the supporting portion 120, the third component 300, i.e., portions of the balls, protrudes out of the bottom 220 of the second component 200, so that the balls first contact the upper surfaces of the ceramic tiles. When the second component 200 is continuously rotated, the balls roll in place on the surfaces of the ceramic tiles to prevent the ceramic tiles from being deviated with the rotation of the second component 200.Embodiment 5

[0057] Embodiments 1 to 4 describe different structures of the third component 300 used for preventing the ceramic tile 20 from being deviated, and also describe different connection methods between the third component 300 and the second component 200 of the second component 200. In embodiments 1 to 4, the second component 200 of the second component 200 needs to rotate to move along the thread of the first component 100. When it is necessary to fix the first component 100, the second component 200 is rotated along the thread of the first component 100 to move towards the ceramic tiles 20. When the second component 200 is separated from the first component 100, it is also necessary to rotate the second component 200 to move away from the ceramic tiles 20. Accordingly, it can be seen that regardless of whether the second component 200 moves towards the ceramic tiles 20 or away from the ceramic tiles 20, it is necessary to rotate the second component 200 along the thread of the supporting portion 120. In practical use, in order to fix the first component 100 between the ceramic tiles, it is necessary to use the second component 200 to rotate along the thread of the supporting portion 120. In addition, the rotation of the second component 200 along the thread of the supporting portion 120 is only to achieve the upward and downward movement of the second component 200, that is, the second component 200 does not play a role of fixing in this part of travel. If the second component 200 can be directly moved along the length direction of the supporting portion 120 at this time instead of rotating the second component 200 along the supporting portion 120 to achieve movement, it will increase the moving speed of the second component 200, thus improving the efficiency.

[0058] Fig. 24 shows embodiment 5. In this embodiment, in a case that the second component 200 does not need to be rotated, the second component 200 can directly move along the length direction of the supporting portion 120, and the second component 200 does not need to be rotated to achieve movement. The difference between this embodiment and embodiments 1 to 4 is that the structure on the second component 200 for connecting the thread of the supporting portion 120 is different. That is to say, the structures and connection methods of the third component 300 in embodiments 1 to 4 may be applied to this embodiment.

[0059] As shown in Fig. 24, a center of the head 210 of the second component 200 is provided with a cylindrical channel 201. Unlike embodiments 1 to 4, the side wall of the cylindrical channel 201 is not provided with a thread. An inner diameter of the cylindrical channel 201 is larger than an outer diameter of the rod-shaped portion 122 of the first component 100. When the cylindrical channel 201 of the second component 200 receives the rod-shaped portion 122 of the first component 100, the second component 200 can directly move along the length direction of the rod-shaped portion 122, and the second component 200 does not need to be rotated.

[0060] A side wall of the head 210 of the second component 200 is provided with a through hole, a rotating member 211 passes through the through hole, and the rotating member 211 is connected to the second component 200 through a pivot shaft 212. The end of the rotating member 211 facing towards the rod-shaped portion 122 of the first component 100 is provided with a tooth 213. The tooth 213 may be engaged with a thread of the rod-shaped portion 122. When the rotating member 211 is in an initial state, the tooth 213 is engaged with the rod-shaped portion 122. At this time, the second component 200 cannot directly move upwards and downwards along the rod-shaped portion 122, and the second component 200 needs to be rotated along the rod-shaped portion 122 to achieve movement. When the rotating member 211 is pressed down, the tooth 213 on it is disengaged from the rod-shaped portion 122. At this time, the second component 200 can directly move along the length direction of the rod-shaped portion 122. Preferably, a reset elastic member (not shown) is provided between the rotating member 211 and the second component 200. The elastic member applies an elastic force to the rotating member 211 to urge the rotating member 211 to reset to the initial state. The elastic member may be a torsion spring sleeved on the pivot shaft 212, or a tension spring, compression spring, elastic sheet, or any other elastic member connected between the rotating member 211 and the second component 200.

[0061] Through this embodiment, when the second component 200 needs to rotate, the rotation of the second component 200 can be achieved; when the second component 200 does not need to rotate and the second component 200 needs to be moved, the second component 200 can be quickly moved and the second component 200 does not need to be rotated to achieve moment, thus improving the efficiency.

[0062] What are described above are specific preferred embodiments of this application. It should be understood that those skilled in the art may make various modifications and changes based on the concept of this application without contributing any inventive labor. Therefore, any technical solution that can be obtained by those skilled in the art based on the concept of this application through logical analysis, reasoning, or limited experiments on the basis of the existing technology should also fall within the scope of protection defined by the claims.

Detailed Description of Embodiments

[0028] Multiple preferred embodiments of this application will be introduced below with reference to the accompanying drawings, so as to make its technical content clearer and easier to understand. This application may be embodied through many different forms of embodiments. the scope of protection of this application is not limited to the embodiments mentioned herein.

[0029] In the accompanying drawings, components with the same structure are labeled with the same numbers, and components with similar structures or functions are labeled with similar numbers. The size and thickness of each component shown in the accompanying drawings are arbitrary. This application does not limit the size and thickness of each component. In order to make the illustration clearer, the thickness of some components in the accompanying drawings has been appropriately exaggerated.

[0030] As shown in Fig. 1, Fig. 13 and Fig. 24, this application further provides a ceramic tile leveling device 10, comprising a first component 100 and a second component 200. The first component 100 comprises a base 110 and a supporting portion 120 vertically extending upwards from the base 110, wherein a joint between the supporting portion 120 and the base 110 is arranged as a tearable portion 124, which can achieve the separation of the supporting portion 120 from the base 110; a lower portion of the supporting portion 120 is configured to be sheet-shaped, and an upper portion is configured to be rod-shaped. When in use, the first component 100 is placed between at least two adjacent ceramic tiles 20, wherein the base 110 is located below the ceramic tiles 20, the lower portion of the supporting portion 120 is located in a gap 21 between the ceramic tiles 20, and the upper portion of the supporting portion 120 protrudes from upper surfaces of the ceramic tiles 20.

[0031] The second component 200 is used for fixing the first component 100 between the ceramic tiles. The second component 200 comprises a cylindrical channel 201 for receiving a rod-shaped portion 122 of the supporting portion 120. When in use, the cylindrical channel 201 of the second component 200 is sleeved on an outer side of the rod-shaped portion 122, and the second component 200 may rotate relative to the rod-shaped portion 122. A bottom 220 of the second component 200 may be used for contacting the upper surfaces of the ceramic tiles 20. The second component 200 may rotate and move upwards and downwards along the supporting portion 120. When the second component 200 rotates and moves downwards along the supporting portion 120, the bottom 220 of the second component 200 is pressed against the upper surfaces of the ceramic tiles 20, thus fixing the first component 100 between the ceramic tiles 20. The bottom 220 of the second component 200 is provided with a third component 300. When the second component 200 rotates downwards along the supporting portion 120, the third component 300 first contacts the surfaces of the ceramic tiles 20, then the second component 200 continues to move towards the ceramic tiles 20, and the third component 300 is fixed on the upper surfaces of the ceramic tiles 20. At this time, the second component 200 continues to rotate, and the third component 300 no longer rotates with the second component 200, but is fixed on the upper surfaces of the ceramic tiles 20, so that the ceramic tiles 20 can be prevented from rotating with the second component 200, thus preventing the ceramic tiles 20 from moving and being misaligned.

[0032] In the existing technology, after the second component rotates downwards along the supporting portion and the second component contacts the upper surfaces of the ceramic tiles, in order to fix the first component as much as possible, the second component still needs to be rotated. At this time, since the second component has already been in contact with the ceramic tiles, pressure will be generated between the second component and the ceramic tiles. Continuing to rotate the second component may cause the ceramic tiles to move or be misaligned, resulting in uneven spacing between the ceramic tiles. However, by using the ceramic tile leveling device 10 provided in this application, the third component 300 is fixed on the upper surfaces of the ceramic tiles 20, so that the ceramic tiles 20 can be prevented from moving or being misaligned due to the rotation with the second component 200, thus making the spacing between the ceramic tiles 20 more even.

[0033] The ceramic tile leveling device 10 in this application will be described below through multiple embodiments.Embodiment 1

[0034] Fig. 1 to Fig. 15 show embodiment 1. As shown in Fig. 4, the first component 100 is provided with a base 110, and a supporting portion 120 is formed by vertically protruding upwards from the base 110, wherein a lower portion of the supporting portion 120 is sheet-shaped, the end of the sheet-shaped portion 121 (the end portion away from the base 110) is approximately conical, an upper portion of the supporting portion 120 is rod-shaped, and the end of the rod-shaped portion 122 is connected to the conical end of the sheet-shaped portion 121. The rod-shaped portion 122 is provided with a thread 123. A joint between the supporting portion 120 and the base 110 is arranged as a tearable portion 124, which can achieve the separation of the supporting portion 120 from the base 110. In some implementations, the thickness of the tearable portion 124 is reduced compared with the sheet-shaped portion 121 of the supporting portion 120, making it easier to tear. In some other implementations, as shown in Fig. 5, the width of the tearable portion 124 is reduced compared with the sheet-shaped portion 121 of the supporting portion 120. At the same time, the tearable portion 124 is provided with a plurality of slot holes 125 that run through along the thickness direction of the sheet-shaped portion 121.

[0035] As shown in Fig. 5 and Fig. 6, an upper surface 111 of the base 110 is used for contacting the lower surfaces of the ceramic tiles 20, and the upper surface 111 of the base 110 is approximately a flat surface. The thickness h of the base 110 decreases from the middle to two ends of the base 110, and the width x of the base 110 also decreases from the middle to two ends of the base 110. The two ends of the base 110 are respectively provided with grooves 112. The grooves 112 run through the base 110 along the thickness direction of the base 110.

[0036] It should be understood that the structure of the first component 100 is not limited to this embodiment, and other structures comprising the threaded rod-shaped portion 122 may be applied to this application. Preferably, the first component 100 is manufactured through integral molding.

[0037] As shown in Fig. 7, a central portion of the second component 200 is provided with a cylindrical channel 201, and the cylindrical channel 201 is used for receiving the rod-shaped portion 122 of the supporting portion 120. A side wall of the cylindrical channel 201 is provided with a thread engaged with the rod-shaped portion 122. The bottom 220 of the second component 200 will contact the upper surfaces of the ceramic tiles. When the second component 200 rotates along the supporting portion 120 towards the ceramic tiles 20, the bottom 220 of the second component 200 contacts the upper surfaces of the ceramic tiles 20, and as the second component 200 rotates, the first component 100 is fixed between the ceramic tiles 20. The shape of the second component 200 does not constitute a limitation on this application. For example, the second component 200 may be square, cylindrical, or in other shapes. As long as the inside of the second component 200 is provided with a cylindrical channel 201 coupled with the rod-shaped portion 122 of the supporting portion 120, the function of fixing the first component 100 by using the second component 200 can be achieved.

[0038] In this embodiment, as shown in Fig. 8, the second component 200 comprises a head 210 provided with a cylindrical channel 201, a bottom 220 provided with a circular flange 221, and a side wall 230 extending from the head 210 to the bottom 220. The insides of the side wall 230 and the bottom 220 are configured to be hollow, thus forming a cavity 231. The cavity 231 is communicated with the cylindrical channel 201 and runs through the entire second component 200.

[0039] The side wall 230 comprises a cylindrical portion 232 in a center and ribs 233 located on a side surface of the cylindrical portion 232, wherein the number of the ribs 233 may be two or more, which are uniformly distributed around the cylindrical portion 232. For example, Fig. 7 shows two ribs 233, and Fig. 15 shows three ribs 233.

[0040] As shown in Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12 and Fig. 15, one side of the circular flange 221 facing towards the ceramic tiles is provided with a third component 300. When the second component 200 rotates along the supporting portion 120 to move towards the ceramic tiles 20, the third component 300 first contacts the surfaces of the ceramic tiles 20, and then the third component 300 no longer rotates with the second component 200. In this way, the second component 200 continues to rotate to fix the first component 100, and the ceramic tiles 20 will not be deviated or misaligned under the fixing effect of the third component 300, thus helping to keep the gap between the ceramic tiles 20 more even. In this embodiment, the third component 300 is a ring-shaped component arranged in the circular flange 221. Specifically, as shown in the figures, the bottom 220 of the second component 200 is provided with at least one arc-shaped limiting portion 222, and the curvature of the limiting portion 222 matches the curvature of the flange 221, that is, the limiting portion 222 is approximately parallel to the flange 221, thus forming a groove 223 between the limiting portion 222 and a side wall of the flange 221. The ring-shaped component is mounted in the groove 223. At the same time, a first protrusion 301 is formed on the ring-shaped component towards the limiting portion 222, a second protrusion 2221 is formed on the limiting portion 222 towards the flange 221, and the first protrusion 301 is clamped on the second protrusion 2221. In this way, the limiting portion 222 connects the ring-shaped component to the flange 221, but the limiting portion 222 does not restrict the degree of freedom of the third component 300 along the circumferential direction of the flange 221. When the third component 300 contacts the surfaces of the ceramic tiles, the second component 200 rotates, while the third component 300 no longer rotates. In some implementations, as shown in the figures, the groove 223 may run through to the upper surface of the flange 221.

[0041] The number of the limiting portions 222 may be set according to the actual needs. For example, Fig. 12 shows two limiting portions 222 and the two limiting portions are symmetrically arranged; Fig. 14 shows three limiting portions 222, which are uniformly arranged along the circumferential direction of the flange 221.

[0042] A process of using the ceramic tile leveling device 10 in this embodiment is as follows: the first component 100 is placed between adjacent ceramic tiles 20, wherein the base 110 is located below the ceramic tiles, the sheet-shaped portion 121 of the supporting portion 120 is located in a gap between the ceramic tiles 20, and the rod-shaped portion 122 of the supporting portion 120 protrudes out of the ceramic tiles 20; the cylindrical channel 201 of the second component 200 is engaged with the rod-shaped portion 122, the second component 200 is rotated so that the second component 200 moves towards the ceramic tiles 20; after the second component 200 moves a certain distance, the third component 300 first contacts the upper surfaces of the ceramic tiles 20, the second component 200 is continuously rotated, the third component 300 is fixed on the upper surfaces of the ceramic tiles 20 and does not rotate with the second component 200 of the second component 200; at this time, as the second component 200 continues to rotate, the ceramic tiles 20 will not be deviated or moved, thus ensuring the evenness of the gap 21 between the ceramic tiles 20.Embodiment 2

[0043] Fig. 16 to Fig. 18 show embodiment 2. In this embodiment, the first component 100 is the same as that in embodiment 1, which will not be repeated here.

[0044] The difference between the second component 200 in this embodiment and the second component 200 in embodiment 1 is that the third component 300 is fixed on the second component 200 in a different way.

[0045] As shown in Fig.17 and Fig. 18, the bottom 220 of the second component 200 is cylindrical and provided with a side wall 240 along the vertical direction; the third component 300 is a ring-shaped component with a U-shaped cross section, and the side wall of the bottom 220 of the second component 200 is accommodated in a U-shaped groove 301 of the ring-shaped component.

[0046] The surface of the side wall 240 of the bottom 220 is provided with a groove 241 arranged along the circumferential direction. An end portion of one side wall of the third component 300 is provided with a protrusion 311 extending towards the second component 200. When the third component 300 accommodates the bottom 220, the protrusion 311 falls into the groove 241, thus connecting the third component 300 to the second component 200. The groove 241 may be provided in the inner surface of the bottom 220, or as shown in the figure, provided in the outer surface of the bottom 220. Accordingly, it can be seen that the groove 241 provided in the side wall 240 of the bottom 220 forms a limiting portion, thus connecting the third component 300 to the second component 200. The groove 241 does not restrict the degree of freedom of the third component 300 along the circumferential direction of the second component 200, that is, the second component 200 can rotate relative to the third component 300.

[0047] The other structures of the second component 200 in this embodiment, such as the cylindrical channel 201, the side wall 230 connecting the head 210 and the bottom 220, and the cavity 231 in the side wall 230, are the same as those in embodiment 1.

[0048] When the ceramic tile leveling device 10 in this embodiment is in use, and when the second component 200 rotates to move downwards along the supporting portion 120, the third component 300 first contacts the upper surfaces of the ceramic tiles 20. When the second component 200 is continuously rotated, the third component 300 can be fixed on the surfaces of the ceramic tiles 20 to prevent the ceramic tiles 20 from being deviated with the rotation of the second component 200.Embodiment 3

[0049] Fig. 19 to Fig. 21 show embodiment 3. In this embodiment, the first component 100 is the same as that in embodiment 1, which will not be repeated here.

[0050] The difference between the second component 200 in this embodiment and the second component 200 in embodiment 1 is that the third component 300 is fixed on the second component 200 in a different way.

[0051] As shown in Fig. 20 and Fig. 21, the bottom 220 of the second component 200 is cylindrical and has a side wall along the vertical direction. The third component 300 is a ring-shaped component mounted on the inner side of the bottom 220, and the bottom end of the third component 300 protrudes out of the bottom 220 of the second component 200. The outer side of the side wall of the bottom 220 is provided with at least one first groove 251 along the circumferential direction. A through hole 252 is formed in the bottom 220 of the first groove 251. The position of the third component 300 corresponding to the first groove 251 is provided with a second groove 320 arranged along a circumferential direction. An arc-shaped component 260 is accommodated in the first groove 251. The inner side of the arc-shaped component 260 is provided with a protruding portion 261. The protruding portion 261 passes through the through hole 252 of the first groove 251 and enters the second groove 320 of the third component 300. In this way, the third component 300 is connected to the second component 200 through the arc-shaped component 260. It should be understood that the number of the first grooves 251 may be set according to the actual needs. For example, the number of the first groove 251 may be one, that is, the first groove 251 forms a circular ring on the side wall of the bottom 220. Alternatively, as shown in the figures, the number of the first grooves 251 is two, which are arranged symmetrically. Alternatively, the number of the first grooves 251 may be multiple, which are uniformly arranged along the circumferential direction of the side wall. It should also be understood that the number of the through holes 252 in the bottom 220 of the first groove 251 may be multiple, that is, a plurality of through holes 252 may be provided in the bottom 220 of one first groove 251. Correspondingly, the number of the protruding portions 261 of the arc-shaped component 260 matches the number of the through holes 252. Through the cooperation between the second groove 320 of the third component 300 and the protruding portion 261 of the arc-shaped component 260, the degree of freedom of the third component 300 along the circumferential direction of the second component 200 is not restricted, and the second component 200 can rotate relative to the third component 300.

[0052] When the ceramic tile leveling device 10 in this embodiment is in use, and when the second component 200 rotates to move downwards along the supporting portion 120, the bottom end of the third component 300 protrudes out of the bottom 220 of the second component 200, so that the third component 300 first contacts the upper surfaces of the ceramic tiles. When the second component 200 is continuously rotated, the third component 300 can be fixed on the surfaces of the ceramic tiles to prevent the ceramic tiles from being deviated with the rotation of the second component 200.Embodiment 4

[0053] Fig. 22 to Fig. 23 show embodiment 4. In this embodiment, the first component 100 is the same as that in embodiment 1, which will not be repeated here.

[0054] The difference between the second component 200 and the second component 200 in embodiment 1 is that the structure of the third component 300 and the way it is fixed on the second component 200 are different.

[0055] As shown in the figures, the bottom 220 of the second component 200 is connected to a connecting member 270, the shape of the connecting member 270 matches the shape of the bottom 220, and it is arranged on the surface of the bottom 220 facing towards the ceramic tiles. The surface of the bottom 220 facing towards the connecting member 270 is provided with a plurality of positioning grooves 271, and positions on the connecting member 270 corresponding to the positioning grooves 271 are provided with through holes 272. The third component 300 is composed of balls, each ball is arranged in the positioning groove 271, and portions of the balls pass through the through holes 272 of the connecting members 270, so that portions of the balls protrude out of the second component 200. Preferably, the plurality of positioning grooves 271 are uniformly arranged along the circumferential direction, so that a plurality of balls are uniformly distributed at the bottom 220. In this embodiment, the third component 300 is composed of balls, and the connecting member 270 forms a limiting portion to connect the balls to the second component 200. After the balls contact the surfaces of the ceramic tiles 20, the second component 200 continues to rotate, and the balls will roll in place, that is, the positions of the balls relative to the ceramic tiles do not change, and the second component 200 rotates relative to the balls, thus preventing the ceramic tiles from being deviated.

[0056] When the ceramic tile leveling device 10 in this embodiment is in use, and when the second component 200 rotates to move downwards along the supporting portion 120, the third component 300, i.e., portions of the balls, protrudes out of the bottom 220 of the second component 200, so that the balls first contact the upper surfaces of the ceramic tiles. When the second component 200 is continuously rotated, the balls roll in place on the surfaces of the ceramic tiles to prevent the ceramic tiles from being deviated with the rotation of the second component 200.Embodiment 5

[0057] Embodiments 1 to 4 describe different structures of the third component 300 used for preventing the ceramic tile 20 from being deviated, and also describe different connection methods between the third component 300 and the second component 200 of the second component 200. In embodiments 1 to 4, the second component 200 of the second component 200 needs to rotate to move along the thread of the first component 100. When it is necessary to fix the first component 100, the second component 200 is rotated along the thread of the first component 100 to move towards the ceramic tiles 20. When the second component 200 is separated from the first component 100, it is also necessary to rotate the second component 200 to move away from the ceramic tiles 20. Accordingly, it can be seen that regardless of whether the second component 200 moves towards the ceramic tiles 20 or away from the ceramic tiles 20, it is necessary to rotate the second component 200 along the thread of the supporting portion 120. In practical use, in order to fix the first component 100 between the ceramic tiles, it is necessary to use the second component 200 to rotate along the thread of the supporting portion 120. In addition, the rotation of the second component 200 along the thread of the supporting portion 120 is only to achieve the upward and downward movement of the second component 200, that is, the second component 200 does not play a role of fixing in this part of travel. If the second component 200 can be directly moved along the length direction of the supporting portion 120 at this time instead of rotating the second component 200 along the supporting portion 120 to achieve movement, it will increase the moving speed of the second component 200, thus improving the efficiency.

[0058] Fig. 24 shows embodiment 5. In this embodiment, in a case that the second component 200 does not need to be rotated, the second component 200 can directly move along the length direction of the supporting portion 120, and the second component 200 does not need to be rotated to achieve movement. The difference between this embodiment and embodiments 1 to 4 is that the structure on the second component 200 for connecting the thread of the supporting portion 120 is different. That is to say, the structures and connection methods of the third component 300 in embodiments 1 to 4 may be applied to this embodiment.

[0059] As shown in Fig. 24, a center of the head 210 of the second component 200 is provided with a cylindrical channel 201. Unlike embodiments 1 to 4, the side wall of the cylindrical channel 201 is not provided with a thread. An inner diameter of the cylindrical channel 201 is larger than an outer diameter of the rod-shaped portion 122 of the first component 100. When the cylindrical channel 201 of the second component 200 receives the rod-shaped portion 122 of the first component 100, the second component 200 can directly move along the length direction of the rod-shaped portion 122, and the second component 200 does not need to be rotated.

[0060] A side wall of the head 210 of the second component 200 is provided with a through hole, a rotating member 211 passes through the through hole, and the rotating member 211 is connected to the second component 200 through a pivot shaft 212. The end of the rotating member 211 facing towards the rod-shaped portion 122 of the first component 100 is provided with a tooth 213. The tooth 213 may be engaged with a thread of the rod-shaped portion 122. When the rotating member 211 is in an initial state, the tooth 213 is engaged with the rod-shaped portion 122. At this time, the second component 200 cannot directly move upwards and downwards along the rod-shaped portion 122, and the second component 200 needs to be rotated along the rod-shaped portion 122 to achieve movement. When the rotating member 211 is pressed down, the tooth 213 on it is disengaged from the rod-shaped portion 122. At this time, the second component 200 can directly move along the length direction of the rod-shaped portion 122. Preferably, a reset elastic member (not shown) is provided between the rotating member 211 and the second component 200. The elastic member applies an elastic force to the rotating member 211 to urge the rotating member 211 to reset to the initial state. The elastic member may be a torsion spring sleeved on the pivot shaft 212, or a tension spring, compression spring, elastic sheet, or any other elastic member connected between the rotating member 211 and the second component 200.

[0061] Through this embodiment, when the second component 200 needs to rotate, the rotation of the second component 200 can be achieved; when the second component 200 does not need to rotate and the second component 200 needs to be moved, the second component 200 can be quickly moved and the second component 200 does not need to be rotated to achieve moment, thus improving the efficiency.

[0062] What are described above are specific preferred embodiments of this application. It should be understood that those skilled in the art may make various modifications and changes based on the concept of this application without contributing any inventive labor. Therefore, any technical solution that can be obtained by those skilled in the art based on the concept of this application through logical analysis, reasoning, or limited experiments on the basis of the existing technology should also fall within the scope of protection defined by the claims.
