Description

Technical Field

[0002] When cutting tiles, the working surface must be kept level and the tiles must be fixed in place to avoid vibration at the cutting position during cutting, which could result in an uneven cut surface or cracks and damage to the tiles.

[0003] In related technologies, tile cutting is carried out on the ground or flat surface. This makes it difficult to control the cutting quality and makes it easy to produce uneven cut marks. Furthermore, adjusting the position of the tile is very inconvenient when cutting it on the ground or flat surface, which affects the cutting efficiency. Utility Model Content

[0004] This application aims to provide a support device that at least helps in cutting tiles and avoids uneven cut marks on the tiles; it reduces the labor intensity of workers and thus improves their construction efficiency.

[0005] This utility model provides a support device, including an inner connecting seat, a first support component, and a second support component.

[0006] The first support component has a support plane for supporting a static object to be supported; the second support component has a support curved surface for supporting the dynamic object to be supported.

[0007] The inner connecting seat is movably connected to the first support component, allowing the support plane to reciprocate vertically and hover at a first preset position; the inner connecting seat is fixedly connected to the second support component; or, the inner connecting seat is fixedly connected to the first support component and movably connected to the second support component, allowing the support curved surface to reciprocate vertically and hover at a second preset position; or...

[0008] The inner connecting seat is movably connected to the first support component, so that the support plane can reciprocate in the vertical direction and be suspended at the first preset position; the inner connecting seat is movably connected to the second support component, so that the support curved surface can reciprocate in the vertical direction and be suspended at the second preset position.

[0009] The vertical height of at least one of the supporting curved surface and the supporting plane can be adjusted to switch between the two.

[0010] As an alternative implementation, the supporting plane and the supporting curved surface are projected in the vertical direction, with the projection of the supporting plane arranged around the projection of the supporting curved surface, or the projection of the supporting curved surface arranged around the projection of the supporting plane.

[0011] As an alternative implementation, the supporting surface is constructed as a ball or roller, so that the ball or roller makes rolling contact with the tile.

[0012] As an alternative, a resistance layer is provided on the support plane.

[0013] As one possible implementation, the inner connecting seat includes an annular structure, the annular structure comprising an outer annular sidewall and an inner annular sidewall, the outer annular sidewall and the inner annular sidewall forming an annular groove.

[0014] The supporting plane is annular and covers the open side of the annular groove.

[0015] The second support component is disposed inside the inner ring sidewall and is threadedly connected to the inner ring sidewall to allow switching between the support curved surface and the support plane.

[0016] As one possible implementation, the second support assembly includes a second support shell, a cover plate covering the opening of the second support shell, a spring, and fasteners.

[0017] The second support shell is provided with a second receiving cavity, and the bottom of the second receiving cavity is provided with a third through hole.

[0018] The cover plate has a protruding mating part on its surface facing the second support shell. The mating part is adapted to the second accommodating cavity. The mating part is disposed in the second accommodating cavity. The spring is disposed in the second accommodating cavity. The fastener passes through the third through hole and is threadedly connected to the cover plate so that the spring is pressed between the cover plate and the bottom of the second accommodating cavity.

[0019] As an implementation method, the surface of the cover plate facing away from the second support shell is provided with the support curved surface.

[0020] As an alternative, the cross-section of the mating part is non-circular.

[0021] As an alternative implementation, an external connector is also included, wherein the external connector has a third accommodating cavity, and the inner surface of the cavity wall of the third accommodating cavity has a second internal thread. The internal connector is located inside the third accommodating cavity, and the sidewall includes an inner surface and an outer surface, wherein the outer surface has a first external thread that is threadedly connected to the second internal thread.

[0022] In one possible implementation, the first support assembly includes a first support shell, the first support shell having a first receiving cavity, the bottom of the first receiving cavity having a first through hole adapted to the diameter of the inner ring sidewall, and the first support shell covering the opening of the outer connecting seat.

[0023] The bottom of the first accommodating cavity has an insert portion on the surface facing away from the first accommodating cavity, and the bottom of the third accommodating cavity has an insert fitting portion on the surface facing away from the third accommodating cavity. The insert fitting portion and the insert portion are inserted into each other so that two adjacent support devices can be stacked.

[0024] The above solution allows switching between the curved and flat support surfaces in the vertical direction by adjusting their respective heights. When the tile cutting equipment is cutting tiles, at least two support devices are positioned below the tile. The support planes of each device support the tile, keeping it horizontal. This facilitates tile cutting and prevents uneven cut marks. The height difference between the tile and the ground facilitates tile position adjustment, thus improving cutting efficiency. After the tile cutting equipment has finished cutting, multiple support devices can be placed between the equipment and the tile to be laid. The support plane A of each device switches to a curved support surface, reducing friction between the tile and the curved surface. This allows the tile to move closer to the tile to be laid via the curved support surface, reducing the labor intensity for workers and improving their efficiency. Attached Figure Description

[0050] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0051] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0052] In practical applications, tiling requires marking and cutting tiles to obtain the appropriate size. In related technologies, tile cutting is performed on the ground or a flat surface, making it difficult to control the cutting quality and easily resulting in uneven cut surfaces. Furthermore, adjusting the position of tiles cut on the ground or flat surface is inconvenient, affecting cutting efficiency. In addition, the cut tiles are still quite heavy, easily tiring workers during installation and thus impacting construction efficiency.

[0053] Therefore, to address the aforementioned problems, this utility model proposes a support device applied to a tile cutting device. When the tile cutting device cuts tiles, refer to... Figure 12 As shown, at least two support devices are positioned beneath the tile, with each device's support plane A supporting the tile to keep it level. This facilitates tile cutting and prevents uneven cut marks. The height difference between the tile and the ground allows for easy tile position adjustment, thus improving cutting efficiency. After the tile cutting equipment has finished cutting the tile, multiple support devices can be placed between the tile cutting equipment and the location of the tile to be laid, as shown in the reference. Figure 13 As shown, the support plane A of each support device is switched to the support curved surface B, which reduces the friction between the tile and the support curved surface B. This allows the tile to move to a position close to the tile to be laid via the support curved surface B, reducing the labor intensity of the workers and thus improving their construction efficiency.

[0054] The following is at least in conjunction with the accompanying drawings. Figures 1-13 The support device is further described as follows: The support device includes: a first support component 10, a second support component 20, and an inner connecting seat 30.

[0055] The first support component 10 has a support plane A, which is used to support the object to be supported in a static state.

[0056] Among them, such as Figure 7 As shown, the supporting plane A is a horizontal plane.

[0057] The second support component 20 is provided with a support surface B, which is used to support the object to be supported in a dynamic state.

[0058] The support material can be ceramic tiles, glass, wood flooring, etc., which are not listed in this embodiment.

[0059] Among them, such as Figure 8 As shown, the supporting curved surface B is constructed as a sphere, hemisphere, arc surface, ellipsoid, etc. This design reduces the contact area between the supporting surface and the tile, which helps the tile move on the supporting surface and avoids wear or scratches on the tile.

[0060] The inner connecting seat 30 is movably connected to the first support component 10 so that the support plane A can reciprocate in the vertical direction and hover at a first preset position; or / and, the inner connecting seat 30 is movably connected to the second support component 20 so that the support curved surface B can reciprocate in the vertical direction and hover at a second preset position; by adjusting the height of at least one of the support curved surface B and the support plane A in the vertical direction, the two can be switched.

[0061] In the first embodiment, such as Figures 14-16 As shown, the inner connecting seat 30 is movably connected to the first support component 10, and the support plane A reciprocates in the vertical direction and is suspended at a first preset position. The inner connecting seat 30 is fixedly connected to the second support component 20, and the support curved surface B is stationary relative to the support plane A.

[0062] In a specific embodiment, the supporting plane A is an annular surface, and the supporting plane A surrounds the supporting curved surface B. The inner connecting seat 30 includes a first telescopic mechanism 33, the movable end of the first telescopic mechanism 33 reciprocates in the vertical direction, and the movable end of the first telescopic mechanism 33 is connected to the first supporting component 10, so as to realize the reciprocating motion of the supporting plane A in the vertical direction and suspend it at a first preset position.

[0063] When the supporting plane A is higher than the highest point of the supporting curved surface B, or when the supporting plane A is level with the highest point of the supporting curved surface B, the supporting plane A supports the static tile; when the supporting plane A is lower than the highest point of the supporting curved surface B, the supporting curved surface B supports the dynamic tile. In this way, by the reciprocating motion of the supporting plane A in the vertical direction while the supporting curved surface B remains stationary, the switching between supporting plane A and supporting curved surface B is achieved.

[0064] In the second embodiment, as Figure 7 and Figure 8 As shown, the inner connecting seat 30 is movably connected to the second support component 20, and the support surface B reciprocates in the vertical direction and hovers at a second preset position; the inner connecting seat 30 is fixedly connected to the first support component 10, and the support plane A is stationary relative to the support surface B. When the highest point of the support surface B is higher than the support plane A, the support surface B supports the dynamically moving tile; when the highest point of the support surface B is lower than the support surface B, or when the highest point of the support surface B is flush with the support plane A, the support surface B supports the statically moving tile. Thus, by the reciprocating motion of the support surface B in the vertical direction while the support plane A remains stationary, the switching between the support plane A and the support surface B is achieved.

[0065] In the third embodiment, as Figures 17-19 As shown, the inner connecting seat 30 is movably connected to the first support component 10, the support plane A reciprocates in the vertical direction and is suspended at the first preset position; the inner connecting seat 30 is movably connected to the second support component 20, the support curved surface B reciprocates in the vertical direction and is suspended at the second preset position.

[0066] In a specific embodiment, the supporting plane A is an annular surface, surrounding the supporting curved surface B. The inner connecting seat 30 includes a second telescopic mechanism 34 and a third telescopic mechanism 35. The movable ends of the second telescopic mechanism 34 and the third telescopic mechanism 35 reciprocate in the vertical direction. The movable end of the second telescopic mechanism 34 is connected to the first supporting component 10, enabling the supporting plane A to reciprocate in the vertical direction and hover at a first preset position. The movable end of the third telescopic mechanism 35 is connected to the second supporting component 20, enabling the supporting curved surface B to reciprocate in the vertical direction and hover at a second preset position.

[0067] Both the supporting plane A and the supporting curved surface B can reciprocate vertically. When the highest point of the supporting curved surface B is higher than that of the supporting plane A, the supporting curved surface B supports the dynamically moving tile; when the highest point of the supporting curved surface B is lower than that of the supporting curved surface A, or when the highest point of the supporting curved surface B is flush with that of the supporting plane A, the supporting curved surface B supports the statically moving tile. Thus, by adjusting the vertical height of both the supporting curved surface B and the supporting plane A through their reciprocating vertical movement, the switching between the two can be achieved.

[0068] The following embodiment uses the second embodiment, in which the inner connecting seat 30 is movably connected to the second support component 20, the support curved surface B reciprocates in the vertical direction and is suspended at a second preset position; the inner connecting seat 30 is fixedly connected to the first support component 10, as described below:

[0069] As an implementation method, the supporting plane A and the supporting curved surface B are projected in the vertical direction, with the projection of the supporting plane A set around the projection of the supporting curved surface B, or the projection of the supporting curved surface B set around the projection of the supporting plane A.

[0070] Among them, such as Figure 2 , 3 As shown in Figures 7 and 8, the supporting plane A is annular. When the supporting plane A and the supporting surface B are projected vertically, the projection plane of the supporting plane A surrounds the projection of the supporting surface B. Of course, it can be understood that the supporting plane A can also be a circumferentially open shape, with the projection plane of the supporting plane A located outside the projection of the supporting surface B when the supporting plane A and the supporting surface B are projected vertically. Alternatively,

[0071] The supporting surface B is annular. The supporting surface B and the supporting plane A are projected vertically, with the projection surface of the supporting surface B surrounding the projection of the supporting plane A. Alternatively, the supporting surface B can also be a non-closed shape circumferentially, with the projection surface of the supporting surface B located outside the projection of the supporting plane A.

[0072] This setup allows for more efficient use of space and facilitates the miniaturization of the support structure.

[0073] It should be noted that the projections of the supporting plane A and the supporting curved surface B in the vertical direction can also be set side by side in the front-back (or left-right) direction.

[0074] In detail, the supporting plane A is annular, and the projection plane of the supporting plane A surrounds the projection plane of the supporting curved surface B. For example:

[0075] The inner connecting seat 30 includes an annular structure, which includes an outer annular sidewall 31 and an inner annular sidewall 32, forming an annular groove 301 between the outer annular sidewall 31 and the inner annular sidewall 32. The supporting plane A is annular and covers the open side of the annular groove 301.

[0076] The inner surface of the inner ring sidewall 32 is provided with a first internal thread 321, and the second support assembly 20 is threadedly connected to the inner ring sidewall 32 to switch between the support curved surface B and the support plane A.

[0077] like Figure 2 As shown, the inner connecting seat 30 includes an annular structure, comprising an outer annular sidewall 31 and an inner annular sidewall 32, which can be coaxially arranged. The lower end face of the inner annular sidewall 32 extends outward in the circumferential direction to the lower end face of the outer annular sidewall 31, thus forming an annular groove 301 between the inner annular sidewall 32 and the outer annular sidewall 31. The inner surface of the inner annular sidewall 32 is provided with a first internal thread 321, which can be continuously or intermittently arranged in the circumferential direction; the outer surface of the outer annular sidewall 31 is provided with a first external thread 311, which can be continuously or intermittently arranged in the circumferential direction. A blind hole 312 with an internal thread is formed by a downward recess in the upper end face of the outer annular sidewall 31.

[0078] like Figure 3 As shown, the first support assembly 10 includes a first support shell 11 and a rubber pad 12. The first support shell 11 includes a first base plate 112 and a first sidewall 111 disposed at the edge of the first base plate 112, the first base plate 112 and the first sidewall 111 forming a first receiving cavity. The first base plate 112 is provided with a first through hole 1121 that matches the diameter of the inner ring sidewall 32, that is, the diameter of the first through hole 1121 can be greater than or equal to the diameter of the inner ring sidewall 32.

[0079] The surface of the first base plate 112 facing away from the first accommodating cavity serves as the end face of the first support shell 11. A first annular protrusion 1124 and a second annular protrusion 1123 are provided on the end face of the first support shell 11. The first annular protrusion 1124 and the second annular protrusion 1123 are coaxially arranged, with the first annular protrusion 1124 surrounding the second annular protrusion 1123. An annular space is formed between the first annular protrusion 1124 and the second annular protrusion 1123. Furthermore, a second through hole 1122 is also provided on the end face of the first support shell 11, located between the first annular protrusion 1124 and the second annular protrusion 1123.

[0080] The rubber pad 12 is annular and fits into the aforementioned annular space, allowing it to be positioned within the space. The thickness of the rubber pad 12 is greater than or equal to the depth of the annular space. Thus, the surface structure of the rubber pad 12 forms a supporting plane A, which is annular. The rubber pad 12 increases the friction between the supporting surface and the tile, contributing to improved stability of the supported tile.

[0081] It should be noted that the rubber pad 12 is provided on the end face of the first support shell 11, which is equivalent to providing a resistance layer on the support plane A. The resistance layer can be made of rubber or silicone material; textures can also be designed on the support plane A, that is, by creating uneven textures on the support plane A, the friction of the support plane A can be increased; or, a resistance coating can be applied to the support plane A, such as epoxy resistance coating, polyurethane resistance coating, alkyd resistance coating, etc.

[0082] like Figure 4 As shown, the second support assembly 20 includes a rolling portion 211 and a threaded portion arranged vertically. The rolling portion 211 contains balls 2111 or rollers, which are constructed as a supporting curved surface B to ensure rolling contact between the balls 2111 or rollers and the tile. This arrangement minimizes frictional resistance between the tile and the supporting surface, further facilitating the movement of the tile on the supporting surface and preventing wear or scratches on the tile. The threaded portion is a second external thread 223, which can be arranged continuously or intermittently in the circumferential direction.

[0083] In addition, the support device also includes an external connecting seat 40. For example... Figure 2 and Figure 6 As shown, the outer connector 40 is provided with a third accommodating cavity 401, and the inner surface of the cavity wall of the third accommodating cavity 401 is provided with a second internal thread 41. The second internal thread 41 can be arranged continuously or intermittently in the circumferential direction.

[0084] like Figure 2 , Figure 7 and Figure 8 As shown, the inner connecting seat 30 is disposed within the third accommodating cavity 401. The first external thread 311 of the outer annular sidewall 31 is threadedly connected to the second internal thread 41 on the cavity wall of the third accommodating cavity 401. The opening of the first support shell 11 is disposed downwards, and the first support shell 11 covers the opening of the outer connecting seat 40, such that the first base plate 112 covers the open side of the annular groove 301, which is equivalent to the support plane A covering the open side of the annular groove 301. The second through hole 1122 of the first support shell 11 is correspondingly disposed with the blind hole 312 of the inner connecting seat 30. Fasteners pass through the second through hole 1122 and are threadedly connected to the blind hole 312, thus the first support shell 11 and the inner connecting seat 30 are fixedly connected.

[0085] The second support assembly 20 passes through the first through hole 1121 of the first support shell 11 and is disposed inside the inner ring sidewall 32 of the inner connecting seat 30, such as... Figure 4 and Figure 2 As shown, the second external thread 223 of the second support assembly 20 is threadedly connected to the first internal thread 321 of the inner ring sidewall 32. When the second support assembly 20 rotates in the positive direction, the rolling part 211 rises, that is, the support surface B rises and can be higher than the support plane A; when the second support assembly 20 rotates in the opposite direction, the rolling part 211 descends, that is, the support surface B descends and can be lower than the support plane A.

[0086] Among them, such as Figure 4 As shown, the second support assembly 20 includes a second support shell 22, a cover plate 21 covering the opening of the second support shell 22, a spring 23, and a fastener 24. The second support shell 22 has a second receiving cavity 221, and the bottom of the second receiving cavity 221 has a third through hole 222. The outer surface of the side wall of the second support shell 22 has a second external thread 223.

[0087] The surface of the cover plate 21 facing away from the second support shell 22 is provided with a rolling part 211, and the surface of the cover plate 21 facing the second support shell 22 is provided with a mating part 212, which is adapted to the second receiving cavity 221 and is disposed in the second receiving cavity 221. The spring 23 is disposed in the second receiving cavity 221, and the fastener 24 passes through the third through hole 222 and the spring 23 and is threadedly connected to the cover plate 21 so that the spring 23 is pressed between the cover plate 21 and the bottom of the second receiving cavity 221.

[0088] Figure 7 or Figure 8 The overall height of the second support component 20 shown is h1. (As shown...) Figure 9 As shown, the outer connecting seat 40 is disengaged from the inner connecting seat 30 by the second internal thread 41 disengaging from the first external thread 311. The outer connecting seat 40 can then be removed. By rotating the fastener 24 with a tool, the compression of the spring 23 can be adjusted, reducing its compression and thus increasing the overall height of the second support assembly 20 from h1 to h2, where h2 > h1. This configuration allows for adjustment of the overall height of the second support assembly 20 to better suit various tile cutting scenarios.

[0089] Furthermore, the cross-section of the mating part 212 is non-circular. For example... Figure 5 As shown, the cross-section of the mating part 212 is approximately a regular hexagon. When rotating the cover plate 21, the mating part 212 and the second accommodating cavity 221 are locked in a non-rotational fit, which can stably drive the side wall of the second support shell 22 to rotate.

[0090] Furthermore, such as Figure 4 , Figure 8 , Figure 9 As shown, the second support shell 22 is also provided with a stop 224, which is located below the second external thread 223.

[0091] In practical applications, the second support component 20 rotates in the positive direction and the rolling part 211 rises. During this process, the second support component 20 disengages from the inner ring sidewall 32, thereby disengaging the second external thread 223 of the second support component 20 from the first internal thread 321 of the inner ring sidewall 32.

[0092] To avoid the aforementioned problems, the second support shell 22 is also provided with a stop 224, which is located below the second external thread 223. The stop 224 cooperates with the lower end stop of the inner ring sidewall 32 to limit the height of the second support assembly 20 in the vertical direction, thereby preventing the second support assembly 20 from dislodging from the inner ring sidewall 32.

[0093] As an implementation method, the end face of the first support shell 11 is provided with an insertion part D, and the end face of the outer connecting seat 40 is provided with an insertion mating part C. The insertion mating part C and the insertion part D are inserted and mated, so that two adjacent support devices can be stacked.

[0094] like Figure 3 As shown, the first annular protrusion 1124, the second annular protrusion 1123 and the rubber pad 12 located between the first annular protrusion 1124 and the second annular protrusion 1123 on the end face of the first support shell 11 together form an inserting protrusion, which is the inserting part D.

[0095] like Figure 6 As shown, the external connector 40 is provided with a third receiving cavity 401. A third annular protrusion 42 and a fourth annular protrusion 43 protrude from the bottom surface of the third receiving cavity 401 facing away from the cavity. The third annular protrusion 42 surrounds the fourth annular protrusion 43, and the third annular protrusion 42 and the fourth annular protrusion 43 are coaxially arranged. A slot is formed between the third annular protrusion 42 and the fourth annular protrusion 43, and the slot is a mating part C.

[0096] The slot of the upper support device and the protrusion of the lower support device engage to allow for the stacking of adjacent support devices, such as... Figure 10 and Figure 11 As shown. This setup, with multiple support devices stacked together, can adapt to severely uneven construction sites, ensuring a suitable height difference between the tiles and the ground. Those skilled in the art can adjust the number of support devices stacked according to site requirements.

[0097] It should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" used above to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
