On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

In the process of laying bricks (such as tiles), leveling the tiles is an important step. At present, the conventional structure of the leveling device for leveling ceramic tiles on the market includes the insert type and the spiral type. In the actual use process, for the spiral structure, the tile is directly pressurized through the spiral body to exert force on the tile. Or, for the insert type structure, push the inserts tightly from the side to achieve the leveling effect of the tiles on both sides. The use of these traditional leveling devices is very time-consuming and laborious: not only need special tools such as wrenches or tension guns for leveling operations during the leveling process, but also need to use hammers or tension guns after the tile leveling effect is achieved. These leveling tools can only be removed when special tools such as special tools or external forces such as kicks break the screw body or the insert base. In addition, the T-shaped leveling pieces of these traditional leveling devices are also left under the laid tiles and cannot be removed. Repeated use, resulting in waste of resources.

Based on the above technical problems, the present disclosure provides a spiral leveling device, which is convenient to operate and can reuse all components including the T-shaped leveling member.

In an exemplary embodiment of the present disclosure, the chassis 11 and the barrel 12 may be integrated.

The present disclosure also provides a spiral leveling device. The leveling seat of the spiral leveling device includes a cylindrical portion and a chassis. The upper end of the barrel abuts against the knob. The chassis extends radially outward from the lower end of the barrel.

In an embodiment, as shown in FIGS. 3 and 4, the inside of the barrel 12 is provided with a sliding groove 13 with a non-circular cross section along the axial direction; the lower end of the screw 4 is provided with a sliding groove 13 with a non-circular cross section. The sliding member 41 can slide relative to the sliding groove 13 in the axial direction but cannot rotate relative to the sliding groove 13, and the lower end of the sliding member 41 is connected with the vertical portion 34 of the leveling member 3. In the present disclosure, the shape of the sliding member 41 is adapted to the shape of the sliding groove 13. For example, the cross section of the sliding member 41 may be rectangular, and correspondingly, the cross section of the sliding groove 13 may also be rectangular.

Specifically, the sliding groove 13 can just accommodate the sliding member 41 to slide up and down, and the space inside the sliding groove 13 is not sufficient for the sliding member 41 to rotate inside the sliding groove 13.

That is, the sliding member 41 can play a limiting role. With this arrangement, the screw 4 can penetrate the knob 2 and the leveling seat 1. In addition, the screw 4 can move relatively inside the threaded through hole 22 of the leveling seat 1. However, due to the limiting effect of the sliding member 41, the screw 4 and the sliding groove 13 cannot rotate with each other. That is, when the leveling seat 1 rotates, it can rotate together with the screw 4, thereby driving the leveling member 3 to rotate together.

It should be noted that the shape of the sliding groove 13 is not limited to the shape exemplified in the figure. In some embodiments, it may also be other shapes, as long as the sliding member 41 can slide axially in the sliding groove 13 but not Just rotate with respect to the chute 13.

In some embodiments, a protruding slide rail may be provided in the axial direction on the inner wall of the barrel, and a slide groove may be provided in the axial direction on the outer wall of the lower part of the screw. Utilizing the cooperation of the sliding rail and the sliding groove, the screw rod can slide in the axial direction inside the barrel.

As shown in Fig. 8, the cross section of the sliding groove 13 is non-circular. In the cross section of the sliding groove 13, the sliding groove 13 may include a guide portion 114 and an extension portion 115 connected between two adjacent guide portions 114, and the extension portion 115 expands outward from the guide portion 114 to form an accommodating space.

The accommodating space can be used to accommodate the leveling element 3, and the specific shape of the accommodating space can be adapted to the cross section of the leveling element 3. For example, when the spiral leveling device is not used, the leveling member 3 can be stored inside the leveling seat 1. Since the leveling member 3 is relatively fragile, the leveling member 3 can be protected from damage by external forces.

The accommodating space can also be used as a reserved space so that the leveling seat can be adapted to other types of leveling parts 3. Since the shape and size of the leveling parts are different in the market, the accommodating space can be reserved to fit the shape of the main leveling parts on the market. The adaptability of such a leveling seat 1 is higher.

As shown in FIG. 8, the extension portion 115 of the sliding groove 13 may be arc-shaped or rectangular. In the same spiral leveling device, the extension 115 of the sliding groove 13 may also include an arc shape and a rectangle shape at the same time.

In the cross section, the guide portion 114 of the sliding groove 13 can be used to accommodate the slider 14, and the shape of the guide portion 114 is adapted to the cross section of the slider 14.

For example, as shown in FIGS. 8 and 9, the sliding member 41 is a rectangular slider with a rounded cross section, and the guide portion 114 of the sliding groove 13 has an arc shape corresponding to the rounded corner of the rectangle.

In some embodiments, the sliding member 41 may also have other shapes, for example, the sliding member 41 may be a plate shape, and the sliding member 41 is a vertical part of the leveling member 3.

As shown in FIG. 9, the sliding member 41 may also be provided with a slot 45 for installing the leveling member 3. For example, the pin 32 can fix the leveling member 3 to the sliding member 41 through the slot 45.

In the present disclosure, in the bottom view of the leveling member 3, the included angle θ between two adjacent horizontal portions 33 of the leveling member 3 is 180°, 90° or 120°.

Fig. 10 is a schematic bottom view showing the structure of a leveling member according to an exemplary embodiment. Fig. 11 is a schematic bottom view showing the structure of a leveling member according to another exemplary embodiment. Fig. 12 is a schematic bottom view showing the structure of a leveling member according to another exemplary embodiment.

In the present disclosure, as shown in FIG. 4, the leveling member 3 may be T-shaped, and the leveling member 3 is inserted upwardly into the bottom of the screw 4 in an inverted T shape, and is fixed by a pin 32.

The leveling member 3 is T-shaped, that is, the bottom cross-section of the leveling member 3 is a cross bar. That is, the horizontal portion 33 of the leveling member 3 is a horizontal cross bar, and the center of the cross bar is connected with the vertical portion 34. And the horizontal part 33 is perpendicular to the vertical part 34, and the horizontal part 33 is parallel to the bottom surface of the chassis 11.

The leveling member 3 is T-shaped, and the included angle θ between two adjacent horizontal portions 33 is 180°. This setting is suitable for leveling two adjacent tiles. When in use, the crossbar is placed under the tile using the gap between the two tiles, so that the crossbar is perpendicular to the boundary of each tile.

After the leveling is completed, the leveling seat 1 is rotated, and then the leveling piece 3 is driven, so that the cross bar rotates 90°. At this time, the crossbar is completely exposed between the gap between the two tiles and can be taken out.

It should be noted that, in the exemplary embodiment of the present disclosure, the bottom cross section of the leveling member 3 may also have other shapes, for example, it may be a cross shape or a Y shape with equal included angles.

As shown in Fig. 11, the bottom cross-section of the leveling member 3 may also be cross-shaped, that is, the angle θ between two adjacent horizontal portions 33 is 90°.

Such a setting can be suitable for leveling four tiles arranged in a cross. When in use, the cross-shaped horizontal part 33 is placed under the tiles by using the gaps between the four tiles.

For example, each first horizontal portion 321 on the horizontal portion 33 may be located in the middle of the corresponding tile, that is, for example, each first horizontal portion 321 may be made to be 45° with the edge of the corresponding tile.

After the leveling is completed, the upper leveling seat 1 is rotated to drive the leveling member 3 so that each first horizontal portion 321 rotates by 45°. At this time, the horizontal portion 33 is completely exposed between the gaps between the two tiles and can be taken out.

As shown in Fig. 12, the bottom cross section of the leveling member 3 is also Y-shaped with equal included angles. That is, the angle θ between two adjacent horizontal portions 33 is 120°.

As shown in FIG. 12, the horizontal portion 33 has three second horizontal portions 322, and the included angle θ between two adjacent second horizontal portions 322 is 120°.

Such a setting can be suitable for leveling three tiles with an included angle θ of 120°. When in use, the Y-shaped horizontal part 33 is placed under the tiles by using the gap between the three tiles.

For example, each second horizontal portion 322 on the horizontal portion 33 can be located in the middle of the corresponding tile, that is, for example, each second horizontal portion 322 can be made to be 60° with the edge of the corresponding tile.

After the leveling is completed, the upper leveling seat 1 is rotated to drive the leveling member 3 so that each second horizontal portion 322 rotates by 60°. At this time, the horizontal portion 33 is completely exposed between the gaps between the two tiles and can be taken out.

The present disclosure also provides a spiral leveling operation method, which includes the steps:

Place the horizontal part of the leveling member below the lower surface of the adjacent part to be leveled, so that the vertical part of the leveling part is located in the gap between the adjacent parts to be leveled and the horizontal part and The gap is at an angle;

Rotate the rotating assembly so that the leveling bottom surface of the leveling seat connected to the rotating assembly gradually approaches and clings to the upper surface of the adjacent component to be leveled;

Rotating the leveling seat makes the horizontal part of the leveling member rotate from the leveling position to the disengagement position corresponding to the gap between the adjacent parts to be leveled.

Fig. 13 is a schematic diagram showing the structure of the spiral leveling device before leveling according to an exemplary embodiment. Fig. 14 is a schematic diagram showing the structure of the spiral leveling device after leveling according to an exemplary embodiment.

Hereinafter, with reference to FIGS. 13 and 14, the spiral leveling device for ceramic tiles according to the embodiment of the present disclosure is taken as an example to describe the spiral leveling method of the present disclosure in detail.

Before use, the upper leveling seat 1, the knob nut 2, the lower leveling iron hook 3, the screw 4, etc. of the ceramic tile spiral leveling device of the embodiment of the present disclosure are all in an assembled state.

The spiral leveling method of the present disclosure includes the following steps:

Positioning step: Place the horizontal part 33 of the lower leveling iron hook 3 under the adjacent tiles 50, so that the vertical part of the lower leveling iron hook 3 is located in the gap between the adjacent tiles 50 and the horizontal part 33 is in contact with each other. The gap is at an angle (for example, perpendicular or oblique to the gap between adjacent tiles 50).

Leveling step: Turn the knob nut 2 so that it can gradually move from the first end 43 of the screw 4 to the positioning slider (slider) 41, so that the combined body of the upper leveling seat 1 and the knob nut 2 moves downward as a whole. As a result, the distance between the lower end surface of the upper leveling seat 1 and the horizontal portion 33 of the lower leveling iron hook 3 is gradually reduced, until the bottom surface of the upper leveling seat 1 completely fits the upper surface of the adjacent tiles 50 at the same time, and the upper leveling seat 1 When the distance from the horizontal part 33 of the lower leveling iron hook 3 can no longer be reduced, the leveling operation is completed.

Specifically, since the knob nut 2 rotates freely on the top of the upper leveling base 1, the rotation of the knob nut 2 will not drive the upper leveling base 1 to rotate, and the lower leveling iron hook 3 remains stationary. During the downward movement of the knob nut 2, the knob nut 2 can generate a downward thrust to the upper leveling seat 1 located below the knob nut 2, so that the upper leveling seat 1 moves downward. During the downward movement of the upper leveling seat 1, the positioning slider 41 slides relatively inside the vertical chute 13, which not only serves as a guide for the movement of the upper leveling seat 1, but also stabilizes the lower leveling iron hook 3 to prevent adjustments. Improper force applied during the leveling process causes the screw 4 and the lower leveling iron hook 3 to bend and so on.

In other words, the rotation of the knob nut 2 is used to make the upper leveling seat 1 and the lower leveling iron hook 3 clamp the ceramic tiles 50, and the interaction force between the upper leveling seat 1 and the lower leveling iron hook 3 is used to connect a plurality of tiles 50 Adjust to be on the same horizontal plane to achieve the effect of tile 50 leveling.

Removal steps: After the tiles 50 are leveled, you can turn the upper leveling seat 1 so that the lower leveling iron hook 3 rotates with the upper leveling seat 1, so that the horizontal part 33 located below the adjacent tiles 50 is rotated to between the adjacent tiles The crevice. At this time, the present state is as shown in FIG. 14, thereby, the entire spiral tile leveling device can be removed smoothly.

Specifically, due to the cooperation between the positioning slider 41 and the vertical sliding groove 13, the upper leveling base 1 and the positioning slider 41 cannot rotate relative to each other. Therefore, when the upper leveling base 1 is rotated, the positioning slider 41 is driven to rotate together. The lower leveling iron hook 3 is fixed with the positioning sliding block 41, that is, when the positioning sliding block 41 rotates, it also drives the lower leveling iron hook 3 to rotate together. In addition, the direction of turning the upper leveling seat 1 can be the same as the direction of rotation of the knob nut 2 (ie, forward rotation), or it can be reversed. During the reverse rotation of the upper leveling seat 1, the upper leveling seat 1 exerts an upward thrust on the knob nut 2, so that the knob nut 2 rotates in the opposite direction relative to the screw 4, so that the lower end surface of the upper leveling seat 1 and the lower leveling iron The distance between the horizontal parts 33 of the hook 3 is increased, and the horizontal parts 33 are taken out. However, the present disclosure is not limited to this, and it is also possible to rotate the upper leveling seat 1 in a forward direction, because the rotation angle is not large, generally not exceeding 90°. Therefore, during the construction process, the operator has a greater degree of freedom of operation in the direction of rotation.

Through the above embodiments, the spiral tile leveling device of the present disclosure can be completely taken out by rotating the upper leveling seat 1 after the tiles are leveled. There is no need to destroy or use other equipment to assist. It saves operation time and reduces the waste of resources.

The placement position of the ceramic tile spiral leveling device during use can be determined according to the shape of the horizontal part of the leveling piece. Fig. 15 is a schematic diagram showing how the spiral leveling device is used according to an exemplary embodiment. Fig. 16 is a schematic diagram showing how the spiral leveling device is used according to another exemplary embodiment.

As shown in FIG. 15, if the included angle θ between two adjacent horizontal portions of the leveling member is 90°, the tile spiral leveling device 10 can be placed in the middle of the gap between four adjacent tiles 50.

As shown in FIG. 16, if the included angle θ between two adjacent horizontal portions of the leveling member is 180°, the tile spiral leveling device 10 can be placed in the middle of the gap between two adjacent tiles 50.
