Description

Technical Field

[0001] The invention relates to the field of building materials, in particular to a squaring and leveling device. Background Art

[0002] At present, when leveling the wall, most people use rib leveling. The steps of rib leveling are as follows: Dotting: Use gypsum cakes to find base points on the wall, connect the points and vertically connect them into lines and calibrate them with a spirit level. Rib punching: Hold a ruler close to the gypsum cake and punch out a rib perpendicular to the ground. Repeat the dotting and rib punching process to make several ribs arranged side by side on the wall. After completing the above construction, several ribs arranged side by side will be left on the wall, and then wait for the ribs to dry and harden. Filling and leveling: Fill the gap with gypsum, and use a ruler to scrape and compact from bottom to top.

[0003] When using gypsum cakes to make points, it is necessary to connect the points and calibrate with a level to complete the rib punching. This process is very cumbersome and it is difficult to quickly make a structure that is convenient for rib punching. After the rib punching is completed, the detachment of the ruler can easily cause the ribs to deform. In addition, the rib punching process is easily affected by manual experience, resulting in insufficient flatness and verticality of the outer surface of the ribs, which ultimately leads to large errors in wall leveling. The precision of such leveling construction is limited, and it is easy to have insufficient wall flatness. When filling and leveling, due to the large roughness of the rib surface and the large width of the rib, the rib will have a relatively large friction resistance to the ruler, which is easy to cause the resistance of the ruler to scrape and smooth, and then it cannot be scraped and smoothed quickly, which is easy to affect the efficiency and quality of wall leveling. Therefore, the existing rib punching leveling has the problems of cumbersome on-site construction, insufficient precision, and low construction efficiency, which is easy to affect the efficiency and quality of house decoration.

[0004] At the same time, when the wall is very flat or poor, there will be gaps between the furniture and the wall, which will make the wall look uneven or tilted, or the furniture look crooked, which will bring a bad visual experience and affect the quality of the house. In addition, the gaps are easy for mosquitoes, dust, and debris to enter, so the inside of the furniture needs to be cleaned frequently to ensure indoor hygiene, which will cause inconvenience to indoor cleaning.

[0005] At the same time, the intersection of the wall and the ceiling is called the "yin angle" in the decoration jargon. During construction at this location, it is difficult for construction workers to make the "yin angle" straight. Usually, it is a curved line, and it is difficult to make the angles of the "yin angle" uniform. In the minimalist decoration style, it seriously affects the decoration effect and reduces the beauty.

[0006] In order to ensure the straightness of the external angle of the wall, it is often achieved by installing external angle lines on the external angle of the wall. Among them, the existing external angle lines mostly adopt a thin strip structure, so the existing external angle lines are relatively soft and the strength of their overall structure is relatively weak. When the straightness of the external angle of the wall itself is very poor, the external angle line stuck on the external angle of the wall is prone to bending as the external angle of the wall is bent, which greatly affects the decorative effect of the building. And this is also likely to lead to a low structural strength of the external angle of the wall, which is likely to lead to poor anti-collision performance of the external angle of the wall, and the external angle of the wall is prone to damage due to small bumps. At the same time, the outer surface of the existing external angle line is mostly a smooth plane. When the external angle line is installed by embedding, the gypsum cannot be firmly attached to the external angle line, and the thickness of the gypsum on the outside of the external angle line is generally thin. In this way, after a period of use, the gypsum on the outside of the external angle line is prone to fall off.

[0007] In addition, the inner corners of building walls are now kept flat and straight by scraping plaster. Such operation is very demanding on the experience of the operators. Even for experienced masters, it is difficult to keep the inner corners flat and straight by scraping plaster alone. Therefore, many inner corners now have poor flatness, skewness, inconsistent upper and lower angles, etc., which will seriously affect the decoration effect and reduce the aesthetics in the minimalist decoration style, thus greatly affecting the decoration quality and effect of the building.

[0008] And when the minimalist style of home decoration is popular nowadays, many of our designers and owners will replace the exposed skirtings in their homes with embedded invisible ones for the sake of beauty. However, there are too many difficulties in implementing the traditional embedded invisible skirtings perfectly.

[0009] Difficulty 1: Details are difficult. Traditional embedded invisible skirtings are installed along the wall, but the walls of all domestic homes are not flat and vertical during decoration, so the skirting will be an uneven line after installation, which seriously affects the visual sense.

[0010] Difficulty 2: Difficult to fix. The traditional invisible concave skirting board is to chisel a groove in the wall, and then fix the concave skirting board in the groove with glue. However, the inside of the groove opened during on-site construction is prone to unevenness, uneven height, and crookedness. The traditional invisible concave skirting board is difficult to fix straight and firmly.

[0011] Difficulty 3: The installation process is difficult (for walls that are painted with materials, excluding wallboards). The traditional concave skirting line will be awkward in the construction sequence of the entire home decoration. The current decoration sequence in China is roughly as follows: 1. Wall-ceiling-floor, 2. Floor-ceiling-wall, 3. Wall-floor-ceiling, etc. If you follow the sequence 1, groove the wall before the wall decoration material is installed, and then install the skirting line after the floor construction is completed. After the skirting line is installed, apply plaster on the wall again to close the skirting line and the wall. Since the painter has already applied putty and paint primer on the wall before the floor construction, the painter will rework it again. Such construction can easily damage the floor decoration materials.

[0012] Based on the above problems, standard leveling cannot be achieved now, and the quality of leveling is very low. Therefore, it is very necessary to design a leveling device to improve the quality of house leveling. Summary of the invention

[0013] The purpose of the present invention is to solve the above problems and shortcomings, and to provide a square leveling device, which includes a pre-buried ceiling line, a pre-buried external angle line, a pre-buried internal angle line, a pre-buried leveling strip, and a pre-buried invisible telescopic skirting line, and all of them are provided with reference convex strips, which can not only facilitate the accurate installation of the square leveling device, but also facilitate the establishment of a very reliable reference, thereby greatly improving the standard of the wall, ceiling line, external angle line, internal angle line and lower wall corner, and thus can make a wall with very high flatness and verticality, and can make very beautiful and standard ceiling line, external angle line, internal angle line and lower wall corner, which can greatly improve the quality and efficiency of square leveling, thereby helping to improve the quality of building decoration. When the ceiling board and furniture are placed against the wall, gaps between the ceiling board and the wall, and between the furniture and the wall are avoided, which can facilitate a better visual experience and facilitate indoor cleaning. The reliability and applicability of the pre-buried ceiling line are very good. In addition, the overall structure of the embedded ceiling line is very simple, and the difficulty and cost of manufacturing it are very low.

This can match the turning structure on the wall, thereby meeting the needs of actual use.

[0028] Because the embedded ceiling line, embedded positive angle line, embedded negative angle line, embedded leveling strip and embedded invisible telescopic skirting line all adopt the embedded structure, it is convenient to install them on the wall stably, thus ensuring the reliable installation of the square leveling device.

[0029] Since the embedded ceiling line, embedded positive angle line, embedded negative angle line, embedded leveling strip and embedded invisible telescopic skirting line are respectively provided with the first reference convex strip, the second reference convex strip, the third reference convex strip, the fourth reference convex strip and the fifth reference convex strip. Through the setting of each reference convex strip, not only can it be used as a reference for their installation, but also a very reliable reference surface can be constructed together through these reference convex strips. So that when plaster is scraped on the wall, there is a very reliable reference, so that it is convenient to manually scrape a flat, straight, and standard corner wall on the wall to avoid the situation of poor flatness, skewness, and inconsistent corner angles on the wall. This can ensure that the wall has a very high flatness and verticality, so as to avoid the situation that the corners of the wall are skewed, the angles of the corners are inconsistent, etc. The use of the square leveling device can greatly improve the quality of the square leveling of the wall, thereby greatly improving the decoration quality of the building.

[0030] Through each reference convex strip, a very accurate and reliable reference can be established, and the accuracy of this reference is minimally affected by workers, which can greatly reduce the error of wall leveling and ensure that the reference has a very high accuracy, thereby greatly improving the accuracy of wall leveling construction, and thus making it easy to make a wall with very high flatness and verticality, and it can make it easy to make a very standard and beautiful wall. The leveling device can greatly improve the quality of wall leveling. The application of the leveling device can directly save the cumbersome "dotting" operation in the existing rib leveling, which can greatly reduce the difficulty of wall leveling and greatly improve the efficiency of wall leveling.

[0031] By using each reference convex strip as a reference, there will be no problem of roughness like the ribs produced by punching. In addition, each reference convex strip is in strip shape, which can greatly reduce the friction between the ruler and each reference convex strip during filling and leveling, thereby greatly reducing the resistance of the ruler to scraping, and making it easier to scrape and level quickly, which also helps to improve the efficiency and quality of wall leveling. The square leveling device can not only greatly reduce the tediousness of on-site construction, but also improve the accuracy and efficiency of construction, thereby helping to improve the efficiency and quality of house decoration.

[0032] The square leveling device can be used to easily create a wall with good flatness, high verticality, and uniform corners, so that when the ceiling board and furniture are placed against the wall, gaps between the ceiling board and the wall, and between the furniture and the wall can be avoided, so that the wall will not appear uneven or tilted, and the ceiling board will not appear crooked or the furniture will fall, which can bring a better visual experience and greatly improve the grade of the house. When there is no gap between the furniture and the wall, mosquitoes, dust, and debris can be prevented from entering the inside of the furniture. In this way, even if the inside of the furniture is not cleaned frequently, the hygiene of the room can still be guaranteed, which helps to improve the convenience of indoor cleaning, and it can also facilitate the improvement of the reliability and applicability of the square leveling device.

[0033] At the same time, the overall structure of the square leveling device is very simple, and it also has the advantages of low manufacturing difficulty and low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] like Figures 1 to 12 As shown, a square leveling device described in the present invention comprises a pre-embedded ceiling line 1, a pre-embedded external corner line 2, a pre-embedded internal corner line 3, a pre-embedded leveling strip 4, and a pre-embedded invisible telescopic skirting line 5, wherein the radial cross-sections of the pre-embedded ceiling line 1, the pre-embedded external corner line 2 and the pre-embedded internal corner line 3 are all in an angled structure, a first reference convex strip 11 is arranged on the vertical inner surface of the pre-embedded ceiling line 1, a second reference convex strip 21 is arranged on the outer corner of the pre-embedded external corner line 2, third reference convex strips 31 are respectively arranged on the two inner surfaces of the pre-embedded internal corner line 3, a fourth reference convex strip 41 is arranged on the outer surface of the pre-embedded leveling strip 4, and a fifth reference convex strip 51 is arranged on the outer surface of the pre-embedded invisible telescopic skirting line 5.

[0062] The squaring and leveling device of the present invention comprises a pre-embedded ceiling line 1, a pre-embedded external corner line 2, a pre-embedded internal corner line 3, a pre-embedded leveling strip 4, and a pre-embedded invisible telescopic skirting line 5, and the radial cross-sections of the pre-embedded ceiling line 1, the pre-embedded external corner line 2, and the pre-embedded internal corner line 3 are all in an angled structure. This can match the turning structure on the wall, thereby meeting the needs of actual use.

[0063] Since the embedded ceiling line 1, the embedded positive angle line 2, the embedded negative angle line 3, the embedded leveling strip 4 and the embedded invisible telescopic skirting line 5 all adopt the embedded structure, it is convenient to stably install on the wall, so as to ensure that the installation of the square leveling device is very reliable.

[0064] The embedded ceiling line 1, embedded positive angle line 2, embedded negative angle line 3, embedded leveling strip 4 and embedded invisible telescopic skirting line 5 are respectively provided with the first reference convex strip 11, the second reference convex strip 21, the third reference convex strip 31, the fourth reference convex strip 41 and the fifth reference convex strip 51. The setting of each reference convex strip can not only serve as a reference for their installation, but also can construct a very reliable reference surface through these reference convex strips. So that when plaster is scraped on the wall, there is a very reliable reference, so that it is convenient to manually scrape the wall to make a flat, straight wall with standard corners, so as to avoid the situation that the wall has poor flatness, skewness and inconsistent corner angles. This can ensure that the wall has a very high degree of flatness and verticality, so as to avoid the corners of the wall being skewed, the angles of each turn being inconsistent, etc. The use of the square leveling device can greatly improve the quality of the wall square leveling, thereby greatly improving the decoration quality of the building. The reliability and applicability of the square leveling device are very high.

[0065] Through each reference convex strip, a very accurate and reliable reference can be established, and the accuracy of this reference is minimally affected by workers, which can greatly reduce the error of wall leveling and ensure that the reference has a very high accuracy, thereby greatly improving the accuracy of wall leveling construction, and thus making it easy to make a wall with very high flatness and verticality, and it can make it easy to make a very standard and beautiful wall. The leveling device can greatly improve the quality of wall leveling. The application of the leveling device can directly save the cumbersome "dotting" operation in the existing rib leveling, which can greatly reduce the difficulty of wall leveling and greatly improve the efficiency of wall leveling.

[0066] By using each reference convex strip as a reference, there will be no problem of roughness like the ribs produced by punching. In addition, each reference convex strip is in strip shape, which can greatly reduce the friction between the ruler and each reference convex strip during filling and leveling, thereby greatly reducing the resistance of the ruler to scraping, and making it easier to scrape and level quickly, which also helps to improve the efficiency and quality of wall leveling. The square leveling device can not only greatly reduce the tediousness of on-site construction, but also improve the accuracy and efficiency of construction, thereby helping to improve the efficiency and quality of house decoration.

[0067] The square leveling device can be used to easily create a wall with good flatness, high verticality, and uniform corners, so that when the ceiling board and furniture are placed against the wall, gaps between the ceiling board and the wall, and between the furniture and the wall can be avoided, so that the wall will not appear uneven or tilted, and the ceiling board will not appear crooked or the furniture will fall, which can bring a better visual experience and greatly improve the grade of the house. When there is no gap between the furniture and the wall, mosquitoes, dust, and debris can be prevented from entering the inside of the furniture. In this way, even if the inside of the furniture is not cleaned frequently, the hygiene of the room can still be guaranteed, which helps to improve the convenience of indoor cleaning, and it can also facilitate the improvement of the reliability and applicability of the square leveling device.

[0068] At the same time, the overall structure of the square leveling device is very simple, and it also has the advantages of low manufacturing difficulty and low manufacturing cost.

[0069] like Figure 3 and Figure 4 As shown, the embedded external corner line 2 includes a corner clip strip 22 with an angled radial section, a positioning reinforcement strip 23 with an angled radial section, and the two inner surfaces of the positioning reinforcement strip 23 are respectively connected to the two outer surfaces of the corner clip strip 22, and the outer angle of the positioning reinforcement strip 23 is an acute angle, and the outer angle of the positioning reinforcement strip 23 constitutes the second reference convex strip 21. In this way, the corner clip strip 22 and the positioning reinforcement strip 23 can play a role in mutual restriction and reinforcement, which can effectively improve the structural strength of the embedded external corner line to avoid the softening of the embedded external corner line. Therefore, when the straightness of the external corner of the wall itself is very poor, the embedded external corner line can be prevented from bending with the bending of the external corner of the wall. The reliability of the embedded external corner line is very high, and it can achieve a better decorative effect. And after the structural strength of the external corner line is improved, it can play the purpose of enhancing the structural strength of the external corner of the wall, thereby helping to improve the anti-collision performance of the external corner of the wall, and then avoid the situation where the external corner of the wall is damaged due to small bumps. Even in a large collision, the outer corner of the wall will not be seriously damaged, so it is very convenient to repair. The reliability and applicability of the embedded outer corner line are very good. Through the corner clip 22, it can be ensured that the embedded outer corner line matches the outer corner of the wall, so that accurate and stable installation can be achieved, which can also make the embedded outer corner line have good applicability.

[0070] By making the outer angle of the positioning reinforcement strip 23 an acute angle and forming the second reference convex strip 21 through the outer angle of the positioning reinforcement strip 23, it can be ensured that the two outer surfaces of the positioning reinforcement strip 23 are inclined toward the inner side of the wall. When the embedded external corner line is installed, the two outer sides of the positioning reinforcement strip 23 can be made deeper from the wall surface, that is, more gypsum can be buried outside the positioning reinforcement strip 23, so that the embedded external corner line can be buried more stably in the external corner of the wall, and the applicability of the embedded external corner line is very good.

[0071] The positioning reinforcement strip 23 can play a dual role of positioning and reinforcement. Among them, "positioning" can not only facilitate the determination of whether the installation position is correct, but also facilitate the accurate positioning of the reference for wall scraping. And "reinforcement" can greatly improve the structural strength of the embedded external angle line. The structural design of the embedded external angle line is very simple and reliable, which can ensure that the embedded external angle line has a very high applicability.

[0072] like Figure 3 and Figure 4 As shown, the radial cross section of the corner clip 22 is right-angled, that is, the corner clip 22 has a clip structure with a 90-degree angle. This can ensure that the pre-buried external corner line has high reliability and can meet the needs of most wall external corners, thereby ensuring that the pre-buried external corner line has high applicability.

[0073] like Figures 1 to 12 As shown, the length direction of each reference convex strip is consistent with the length direction of the corresponding component on the squaring and leveling device. This not only ensures that each reference convex strip has a longer length, but also facilitates the formation of a straight reference and the formation of reference convex strips on each component, thereby helping to further improve the applicability of the squaring and leveling device.

[0074] like Figures 1 to 12 As shown, the top surface of each reference convex strip is an arched arc surface. This not only plays a very good reference role, but also reduces the resistance of plastering on each reference convex strip, so as to facilitate the operator to apply plaster on each reference convex strip, thereby ensuring that the plaster application can be carried out very smoothly, and then it is convenient to improve the efficiency of leveling, which helps to further improve the applicability of the leveling device.

[0075] like Figures 1 to 12 As shown, each reference convex strip is a cone structure with a wide inner side and a narrow outer side. This not only facilitates decoration, but also ensures that each reference convex strip has a high structural strength, thereby helping to improve the reliability and applicability of the square leveling device.

[0076] like Figure 3 and Figure 4 As shown, the inner angle of the positioning reinforcement strip 23 is equal to the outer angle of the corner clamping strip 22, that is, when the outer angle of the corner clamping strip 22 is 90 degrees, the inner angle of the positioning reinforcement strip 23 is also 90 degrees. This can facilitate the formation of a more reliable embedded external angle line.

[0077] like Figure 4 As shown, the outer angle α of the positioning reinforcement strip 23 is 53 degrees. This not only ensures that the positioning reinforcement strip 23 has a high structural strength, but also ensures that a sufficient thickness of gypsum can be buried on the outer side of the positioning reinforcement strip 23, thereby helping to improve the reliability and applicability of the embedded external angle line.

[0078] like Figure 3 and Figure 4 As shown, in the actual manufacturing process, the two sides of the bending part of the embedded external angle line 2 can be made symmetrical or asymmetrical.

[0079] like Figure 5 and Figure 6 As shown, the radial cross section of the embedded internal angle line 3 is in a right angle shape. This can facilitate the standard 90-degree angle when constructing at the internal angle, which can not only ensure that the embedded internal angle line has high reliability, but also ensure that the embedded internal angle line can meet the needs of most building internal angles, thereby ensuring that the embedded internal angle line has high applicability.

[0080] like Figure 1 and Figure 2 As shown, the embedded ceiling line 1 includes a limit strip 12 and a first embedded strip 13. The limit strip 12 and the first embedded strip 13 are arranged horizontally, and the rear side of the limit strip 12 is connected to the upper side of the first embedded strip 13. The first reference convex strip 11 is arranged on the front surface of the first embedded strip 13. The limit strip 12 plays a very accurate and stable limiting role on the ceiling board, which helps to improve the accuracy and stability of the installation and positioning of the end of the ceiling board. The reliability of the square leveling device is very good. The first embedded strip 13 can achieve the effect of embedded positioning, thereby ensuring the stability and reliability of the installation and positioning of the embedded ceiling line. After the first embedded strip 13 is installed in an embedded manner, the exposure amount of the embedded ceiling line can also be reduced, thereby reducing the impact of the embedded ceiling line on the aesthetics of the house decoration.

[0081] like Figure 2 As shown, the first embedded strip 13 constitutes the vertical part of the embedded ceiling line 1, and the limit strip 12 constitutes the horizontal part of the embedded ceiling line 1. In this way, a reliable embedded ceiling line 1 can be formed.

[0082] like Figure 1 and Figure 2 As shown, a limiting groove 121 is provided on the front lower surface of the limiting strip 12. The limiting groove 121 is provided on the front lower surface of the limiting strip 12, which allows the end of the ceiling plate to be accurately embedded, which can facilitate the ceiling plate to have a very accurate and stable limiting effect, and can facilitate the installation and removal of the ceiling plate, thereby helping to further improve the reliability and applicability of the square leveling device.

[0083] like Figure 1 and Figure 2 As shown, a toothed surface 122 is provided on the upper groove wall of the limiting groove 121. This can enhance the friction force so that the ceiling board can be embedded in the limiting groove 121 very stably, which helps to further improve the reliability of the square leveling device.

[0084] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the inner corner or one side of the inner corner of the embedded ceiling line 1 is provided with a first concave groove 14, and the inner corner or one side of the inner corner of the embedded inner corner line 3 is provided with a second concave groove 32. Through each concave groove, a very clear process seam can be formed, so that the two surfaces constituting the "inner corner" can be clearly separated, which can bring a very good visual experience. The two concave grooves can play a very good decorative effect at the "inner corner", which can ensure that the "inner corner" is very coordinated and beautiful. This helps to improve the aesthetics and grade of the "inner corner" decoration, and then helps to improve the quality of house decoration. In addition, the first concave groove 14 and the second concave groove 32 can be used to install decorative objects or objects with other functions, which can facilitate the accurate positioning of the objects to be installed, thereby helping to improve the stability and accuracy of the installation and positioning of the relevant objects, which can ensure that the embedded ceiling line has high reliability and applicability. This can also prevent the "yin corner" of the relevant objects from being too abrupt, so that it can meet more usage requirements while ensuring the decorative effect. The square leveling device has a very high applicability. At the same time, the two concave grooves can also be used for accurate embedding of decorative strips, color strips and light strips. By embedding decorative strips, the aesthetics and quality of wall decoration can be improved, so that the decorative quality of the wall can be greatly improved. Such a structure helps to further improve the applicability of the square leveling device. The two concave grooves can make the corresponding "yin corner" completely separated in visual sense, which can create a suspended visual sense. And when the "yin corner" is plastered, there is no need to worry about the difficulty of constructing the "yin corner" at the intersection of the two surfaces. And when the two surfaces constituting the "yin corner" are painted with brushing materials and are of the same color, the transition lines of the two surfaces can be avoided from being blurred, thereby avoiding the embarrassing illusion of not being able to distinguish the transition lines, and thus achieving a better decoration effect.

[0085] like Figure 1 and Figure 2 As shown, the limit strip 12 and the first embedded strip 13 are both slat structures, and the limit strip 12 and the first embedded strip 13 are perpendicular to each other. The limit strip 12 and the first embedded strip 13 together constitute a pre-embedded ceiling line 1 with a radial cross-section of 90 degrees. This can conveniently make the "inner angle" at the intersection of the ceiling surface and the wall surface 90 degrees, solving the problem that it is difficult to achieve a standard 90-degree angle at the inner angle during construction. In this way, it can ensure that the pre-embedded ceiling line has high reliability and can also ensure that the pre-embedded ceiling line can meet the installation of most ceiling panels, thereby ensuring that the pre-embedded ceiling line has high applicability.

[0086] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the first concave groove 14 and the second concave groove 32 are both in a straight strip structure, and their two ends are respectively passed through the two ends of the corresponding components. This not only facilitates molding and manufacturing, but also forms very straight concave grooves, which can play a very good decorative role.

[0087] like Figure 5 and Figure 6 As shown, since the radial cross section of the embedded internal corner line 3 is in an angle shape, an inner corner and an outer corner are formed at the transition between the inner and outer sides of the embedded internal corner line 3. The outer corner of the embedded internal corner line 3 is the corner on the outer side of the embedded internal corner line 3, and the inner corner of the embedded internal corner line 3 is the corner on the inner side of the embedded internal corner line 3. In this way, a very reliable embedded internal corner line can be formed.

[0088] like Figure 3 and Figure 4 As shown, since the radial cross-sections of the corner clamping strip 22 and the positioning reinforcement strip 23 are in an angle shape, an inner corner and an outer corner are formed at the transition between the inner and outer sides of the corner clamping strip 22 and the positioning reinforcement strip 23. The outer corner of the corner clamping strip 22 is the corner on the outer side of the corner clamping strip 22, the inner corner of the corner clamping strip 22 is the corner on the inner side of the corner clamping strip 22, the outer corner of the positioning reinforcement strip 23 is the corner on the outer side of the positioning reinforcement strip 23, and the inner corner of the positioning reinforcement strip 23 is the corner on the inner side of the positioning reinforcement strip 23. In this way, a very reliable embedded external angle line can be formed.

[0089] like Figures 1 to 12 As shown, a first concave-convex portion 15 is provided on the vertical inner surface of the embedded ceiling line 1, and the maximum height of the first concave-convex portion 15 is smaller than the maximum height of the first reference convex strip 11; second concave-convex portions 24 are respectively provided on the two outer surfaces of the embedded positive angle line 2, and the maximum height of the second concave-convex portion 24 is smaller than the maximum height of the second reference convex strip 21; third concave-convex portions 33 are respectively provided on the two inner surfaces of the embedded negative angle line 3, and the maximum height of the third concave-convex portion 33 is smaller than the maximum height of the third reference convex strip 31; a fourth concave-convex portion 42 is provided on the outer surface of the embedded leveling strip 4, and the maximum height of the fourth concave-convex portion 42 is smaller than the maximum height of the fourth reference convex strip 41; a fifth concave-convex portion 52 is provided on the outer surface of the embedded invisible telescopic skirting board 5, and the maximum height of the fifth concave-convex portion 52 is smaller than the maximum height of the fifth reference convex strip 51. The various concave and convex parts can not only enhance the structural strength, but also facilitate the more stable attachment of gypsum. After long-term use, the gypsum is less likely to crack or fall off, which makes it easy to build a very reliable wall. The various concave and convex parts can enhance the structural strength, which helps to further improve the reliability of the square leveling device.

[0090] like Figure 3 and Figure 4 As shown, the two second concave-convex portions 24 are respectively arranged on the two outer surfaces of the positioning reinforcement strip 23. In this way, a reliable embedded external angle line 2 can be formed.

[0091] like Figure 3 and Figure 4 As shown, the maximum vertical distance from each vertex on the two second concave-convex parts 24 to the corresponding outer surface on one side of the corner clip 22 is less than the vertical distance from the top of the positioning reinforcement strip 23 to the corresponding outer surface on the corner clip 22. On the two outer surfaces of the corner clip 22, the vertical distance from each vertex on the two second concave-convex parts 24 to the corresponding outer surface on the second concave-convex parts 24 gradually decreases in the direction away from the outer corner of the positioning reinforcement strip 23. In this way, when plaster is scraped on the two second concave-convex parts 24, it can be ensured that the two second concave-convex parts 24 are all located in the plaster, that is, the two second concave-convex parts 24 are located in the scraped wall surface, which can not only prevent the two second concave-convex parts 24 from affecting the scraping of the walls on both sides of the external corner, but also prevent the two second concave-convex parts 24 from being exposed to the outside, and can prevent the two second concave-convex parts 24 from affecting the positioning reinforcement strip 23 to form a convenient reference benchmark. This helps to further improve the reliability and applicability of the square leveling device.

[0092] like Figures 1 to 12 As shown, the first concave-convex part 15 is provided with a first embedding groove 16, the second concave-convex part 24 is provided with a second embedding groove 25, the third concave-convex part 33 is provided with a third embedding groove 34, the fourth concave-convex part 42 is provided with a fourth embedding groove 43, and the fifth concave-convex part 52 is provided with a fifth embedding groove 53. Each embedding groove can be used for embedding kraft paper, so that the kraft paper can be stably and accurately positioned on each component of the square leveling device, so that a more gentle transition can be formed between each component and the gypsum, and each component can be more reliably connected with the gypsum, which helps to further improve the reliability of the square leveling device. In addition, this can reduce the influence of thermal expansion and contraction and collision on the square leveling device, so as to avoid the cracking of the gypsum at the side of each component in these cases, so as to ensure that the wall can maintain a good decorative effect for a long time, which helps to further improve the reliability and applicability of the square leveling device. By opening each embedding groove on the corresponding concave-convex part, it is convenient to stick the kraft paper on the concave-convex part, which can limit the kraft paper through the concave-convex part, thereby improving the reliability of the kraft paper installation and positioning, and thus ensuring that the square leveling device has a very high reliability.

[0093] like Fig.11 and Fig.12As shown, in the actual manufacturing process, more than two embedding grooves can be opened on the concave and convex parts of some components of the square leveling device. For example, two embedding grooves, one large and one small, are opened on the embedded external angle line 2. This can facilitate the use of kraft paper of different thicknesses and different installation positions, thereby meeting more usage requirements, and further helping to further improve the applicability of the square leveling device. And this can further improve the adhesion of gypsum on the concave and convex parts.

[0094] Figures 1 to 12 As shown, in the actual manufacturing process, each embedding groove can be made into a long strip, and the inner wall of each embedding groove is in the shape of the letter C. This can facilitate the stable embedding of the entire side of the kraft paper, and it can be convenient for processing, which helps to improve the stability and reliability of the kraft paper embedding, thereby helping to further improve the reliability of the square leveling device.

[0095] During installation, one end of the kraft paper is embedded in the embedding groove, and the other end of the kraft paper is away from the embedding groove, and the kraft paper is covered on the side of the corresponding component. In this way, the installation requirements can be met.

[0096] like Figures 1 to 12 As shown, each concave-convex part is in a wave-shaped structure, which can ensure that the structure of each concave-convex part is very simple and reliable, so that it can be conveniently formed in one piece, thereby helping to further improve the convenience of manufacturing the square leveling device.

[0097] like Figures 1 to 12 As shown, each concave-convex part is connected to the side wall of the corresponding reference convex strip, and the height of each convex point on the concave-convex part is gradually reduced in the direction away from the reference convex strip. By connecting the concave-convex part with the reference convex strip, they can play a role of mutual reinforcement, which can not only enhance the reliability and stability of the connection between each reference convex strip and the corresponding component, but also improve the reliability and stability of each concave-convex part, thereby helping to improve the structural strength of the square leveling device, and further help to further improve the reliability of the square leveling device. By adopting the concave-convex part with the above thickness structure, it can be ensured that the gypsum layer away from the reference convex strip is generally gradually thickened, and the concave-convex part itself facilitates the stable attachment of the gypsum, which can effectively improve the stability and reliability of the gypsum attachment, so as to avoid the gypsum from falling off, thereby helping to further improve the reliability and applicability of the square leveling device. And by connecting the concave-convex part with the reference convex strip, it can be ensured that each component of the square leveling device has a compact structure, so that it can be convenient for storage, transportation and installation.

[0098] like Figures 1 to 12As shown, the vertical outer surface of the embedded ceiling line 1 is provided with a first storage groove 17, the two inner surfaces of the embedded external corner line 2 are provided with second storage grooves 26, the two outer surfaces of the embedded internal corner line 3 are provided with third storage grooves 35, the inner surface of the embedded leveling strip 4 is provided with a fourth storage groove 44, and the inner surface of the embedded invisible telescopic skirting line 5 is provided with a fifth storage groove 54. Each storage groove can be used to store plaster or glue to ensure that there is sufficient plaster or glue between each component of the square leveling device and the wall, so that the square leveling device can be stably installed on the wall, which helps to further improve the reliability of the installation and positioning of the square leveling device.

[0099] like Figures 1 to 12 As shown, in the actual manufacturing process, each storage groove can be made to penetrate the side wall and / or the end face of the corresponding component. This can facilitate the discharge of excess plaster or glue from the side wall and / or the end face of the component to avoid them affecting the normal installation positioning and adjustment of the square leveling device, which can facilitate the installation of the square leveling device more quickly, thereby helping to further improve the convenience and accuracy of the installation positioning of the square leveling device.

[0100] like Figures 1 to 12 As shown, in all documents, the inner surfaces of the embedded ceiling line 1, embedded external corner line 2 and embedded external corner line 2 all refer to the inner surface of the angled structure, the outer surfaces of the embedded ceiling line 1, embedded external corner line 2 and embedded external corner line 2 all refer to the outer surface of the angled structure, the outer surfaces of the embedded leveling strip 4 and embedded invisible telescopic skirting line 5 all refer to the surface facing the outside of the wall, and the inner surfaces of the embedded leveling strip 4 and embedded invisible telescopic skirting line 5 all refer to the surface facing the inside of the wall. In this way, a reliable square leveling device can be formed.

[0101] like Figures 1 to 11As shown, the vertical part of the embedded ceiling line 1 is provided with a plurality of first through holes 18, the ends of the embedded positive angle line 2 on both sides of the corner are provided with a plurality of second through holes 27, the ends of the embedded negative angle line 3 on both sides of the corner are provided with a plurality of third through holes 36, the embedded leveling strip 4 is provided with a plurality of fourth through holes 45, and the embedded invisible telescopic skirting line 5 is provided with a plurality of fifth through holes 55. Each through hole can facilitate the discharge of excess plaster or glue, so as to ensure that there is suitable plaster or glue inside the components of the square leveling device, and then it is convenient to quickly fix the components of the square leveling device, which helps to further improve the installation efficiency of the square leveling device. Moreover, each through hole can also facilitate the setting of the components of the square leveling device by plaster or glue, so as to facilitate more stable fixing of the square leveling device on the wall, and then it helps to further improve the stability and reliability of the installation and positioning of the square leveling device. By opening each through hole, when the position of each reference convex strip is adjusted by pressing, excess gypsum mud on the inside can pass through, thereby preventing excess gypsum mud from affecting the adjustment of the square leveling device. Such a structure helps to improve the convenience of adjusting the square leveling device.

[0102] like Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 8 and Fig.11 As shown, the through holes at corresponding positions are arranged side by side along a straight line. This not only facilitates the formation of a reliable square leveling device, but also reduces the influence of the through holes on the structural strength of the square leveling device, thereby ensuring that the square leveling device has high reliability.

[0103] like Figures 1 to 11 , Fig.13 As shown, the through holes on each component of the square leveling device respectively penetrate the storage grooves at the corresponding positions, and the through holes are staggered with the corresponding concave and convex parts. By making each through hole penetrate the corresponding storage groove, it is more convenient to discharge the excess plaster or glue, and the reliability and stability of the plaster or glue fixing the square leveling device can be further enhanced. By staggering the opening, it is convenient to ensure that the square leveling device has a high structure through the concave and convex parts, and it can avoid that the through holes affect the structural strength of the square leveling device, so as to ensure that the square leveling device has high reliability.

[0104] like Figure 3 and Figure 4As shown, the width of the positioning reinforcement strip 23 is smaller than the width of the corner clamping strip 22, and each second through hole 27 is located outside the side wall of the positioning reinforcement strip 23. This can ensure that the positioning reinforcement strip 23 and the corner clamping strip 22 are assembled into a reliable structure, and can also prevent the positioning reinforcement strip 23 from affecting the opening and penetration of the second through hole 27, which can form a very reliable embedded external angle line.

[0105] like Figures 1 to 6 As shown, the outer corner of the embedded ceiling line 1 is provided with a first clearance gap 19, the inner corner of the embedded external corner line 2 is provided with a second clearance gap 28, and the outer corner of the embedded internal corner line 3 is provided with a third clearance gap 37. By providing each clearance gap, it is convenient to stagger the defects on the wall, external corner and internal corner, such as: the existence of skew, convex blocks, etc., so as to reduce the influence of these defects on the installation of related components, which can facilitate the improvement of the convenience, stability and reliability of the installation and positioning of the square leveling device. In some use cases, each clearance gap can also be used to store plaster or glue to ensure that there is sufficient plaster or glue between the related components and the wall, so as to ensure that the related components can be installed on the wall very stably, which helps to further improve the reliability of the square leveling device. And after using each clearance gap, the installation of the related components can be satisfied without additional treatment of the wall defects, which helps to improve the convenience and efficiency of the installation of the square leveling device.

[0106] like Figures 1 to 6 As shown, each clearance gap can be made into a right angle or a C-shaped wall. This not only can make each clearance gap have a better clearance effect, but also can facilitate the opening of each clearance gap, thereby helping to further improve the reliability and applicability of the square leveling device.

[0107] like Figure 3 and Figure 4 As shown, the second clearance gap 28 penetrates to the positioning reinforcement strip 23. This ensures that the second clearance gap 28 has a large volume, so that it can be easily installed on the wall corner with large defects, which helps to improve the application range of the embedded external angle line.

[0108] like Figure 8 and Fig.10As shown, a groove portion 46 in the same direction as its length direction is provided on one side wall of the embedded leveling strip 4. This can form a very clear dividing line through the groove portion 46 when the embedded leveling strip 4 is used to separate different decorative surfaces, such as different colors, different shades, different pictures, different materials, etc. And because the groove portion 46 has a groove structure, it can not only play a role in obviously separating different decorative surfaces, but also bring a very good visual experience. The groove portion 46 can play a very good decorative effect at the separation of the decorative surface, which can ensure that the overall wall surface is very coordinated and beautiful. Thereby helping to improve the aesthetics and grade of wall decoration, and then helping to improve the quality of house decoration. The two decorative surfaces can be completely separated in visual sense through the groove portion 46. Since the two decorative surfaces are separated from each other, there is no need to worry about the difficulty of construction at the intersection of the two surfaces when plastering the two decorative surfaces. Moreover, when two adjacent non-coplanar decorative surfaces are both painted with the same color, the transition lines between the two decorative surfaces can be avoided from being blurred. Even if the two adjacent decorative surfaces are coplanar, the transition lines can be ensured to be very clear, thereby making it easy to clearly distinguish the transition lines between the two decorative surfaces, thereby avoiding the embarrassing illusion of not being able to distinguish the two decorative surfaces, which also helps to improve the decoration quality of the house.

[0109] The slots on the groove portion 46 can be used to install decorative objects or objects with other functions, which can facilitate accurate positioning of the objects to be installed, thereby helping to improve the stability and accuracy of the installation and positioning of the relevant objects, which can ensure that the embedded leveling strip has high reliability. This can also prevent the relevant objects from being too abrupt at the separation of the decorative surface, thereby ensuring the decorative effect and meeting more usage requirements. The embedded leveling strip has a very high applicability.

[0110] like Figure 8 and Fig.10 As shown, the groove portion 46 can be used as a decorative groove left empty so as to leave a good decorative structure on the wall. At the same time, the groove portion 46 can also be used for accurate embedding of decorative color strips and light strips. By embedding decorative strips, the aesthetics and quality of wall decoration can be improved, thereby greatly improving the decorative quality of the wall. Such a structure helps to further improve the applicability of the square leveling device.

[0111] like Figure 8 and Fig.10 As shown, the groove portion 46 is a straight strip structure. This can form a very straight dividing line through the groove portion 46, which can play a very good role in dividing and decorating. This can facilitate the production of straight transition lines, thereby improving the decoration effect in a minimalist decoration style, and further improving the aesthetics.

[0112] In the actual manufacturing process, the groove portion 46 can also be made into other shapes such as arc, wave, tooth, pattern, etc., which can meet more partition decoration requirements.

[0113] like Figure 8 and Fig.10 As shown, the groove portion 46 extends along the length direction of the embedded leveling strip 4, and the notch of the groove portion 46 faces the same direction as the top of the fourth reference convex strip 41, that is, the notch of the groove portion 46 faces the outside of the wall, and the notch on the groove portion 46 penetrates to the end surfaces of both ends of the groove portion 46. This not only facilitates molding and manufacturing, but also forms a more intuitive decorative slot, which can bring a very good visual experience. The embedded leveling strip 4 can further improve the aesthetics and grade of the decorative surface partition, thereby helping to further improve the quality of house decoration.

[0114] like Figure 8 and Fig.10 As shown, the radial cross section of the groove portion 46 is a concave structure. This not only enables the groove portion 46 to have a very simple structure, but also ensures that the groove portion 46 can well meet the needs of actual use, which helps to further improve the applicability of the embedded leveling strip 4.

[0115] like Figure 8 and Fig.10 As shown, since the groove portion 46 is used for decoration or for mounting decorations, and the groove portion 46 is located on the side wall of the embedded leveling strip 4, there is no need to apply plaster on the groove portion 46. In this way, the thickness of the groove portion 46 will not affect the normal use of the fourth reference convex strip 41, which can ensure that the embedded leveling strip 4 can well meet the actual use requirements.

[0116] like Figure 8 and Fig.10 As shown, the side walls of the fourth reference convex strip 41 are respectively connected to the groove portion 46 and the fourth concave-convex portion 42. Such connection can achieve mutual reinforcement between them, which helps to further improve the reliability of the fourth reference convex strip 41, the groove portion 46 and the fourth concave-convex portion 42, so that the embedded leveling strip 4 with better structural strength can be obtained, and then the reference established by the fourth reference convex strip 41 can be ensured to be very reliable and stable, which helps to further improve the reliability and applicability of the embedded leveling strip 4.

[0117] like Figures 7 to 10 As shown, the embedded leveling strip 4 is a strip-shaped structure, which can ensure that the embedded leveling strip 4 has high reliability and facilitate the manufacture and embedding of the embedded leveling strip 4, thereby ensuring that the embedded leveling strip 4 has high applicability.

[0118] like Fig.11 and Fig.12As shown, the embedded invisible telescopic skirting 5 includes a second embedded strip 56 and a telescopic bead 57. The fifth reference convex strip 51 is arranged on the outer surface of the second embedded strip 56, and the telescopic bead 57 can be arranged vertically and telescopically on the bottom surface of the second embedded strip 56. By adopting the second embedded strip 56, the embedded positioning requirement can be achieved, which can facilitate the embedded invisible telescopic skirting 5 to be installed in place very stably and reliably, and the reliability of the embedded invisible telescopic skirting 5 is very good.

[0119] By vertically telescopically arranging the telescopic bead 57 on the bottom surface of the second embedded strip 56, the telescopic bead 57 can move vertically below the second embedded strip 56, so that when the second embedded strip 56 is embedded, the telescopic bead 57 can well form an invisible skirting. The pre-embedded invisible telescopic skirting 5 has the advantages of stable and firm installation, no falling due to collision, no dust accumulation on the top, no process of cleaning the dust on the top, easy cleaning, ensuring the quality of wall decoration, and no influence on the placement of the home against the wall.

[0120] The use of a telescopic strip 57 that can be telescopic vertically can also make up for the vertical upward or downward installation error to avoid mutual influence between the construction of the wall and the ground. The telescopic strip of the embedded invisible telescopic skirting 5 can also fit the ground well. After ensuring that the telescopic strip presses the ground decoration material, there will be no gap between the telescopic strip and the ground decoration material. Even if the ground is uneven, it will not affect the accurate installation of the embedded invisible telescopic skirting 5, and will not affect the normal use of the embedded invisible telescopic skirting 5, which can constitute an invisible telescopic adjustable skirting. The applicability of the embedded invisible telescopic skirting 5 is very good, and this can reduce the difficulty of construction.

[0121] The embedded invisible telescopic skirting 5 can be used to adjust and correct the flatness of the wall surface, and can adapt to the uneven ground surface and can be adjusted flexibly. It perfectly solves all the pain points encountered during construction. There is no need to worry about the embedded invisible telescopic skirting 5 being difficult to install, fix, adjust, or uneven due to uneven walls, non-standard slots, and uneven ground surfaces, and there is no need to worry about the time point for the construction of the embedded invisible telescopic skirting 5. It also greatly improves the construction efficiency on site, and improves the construction standards and construction level.

[0122] When the embedded invisible telescopic skirting 5 is actually installed, the groove on the lower side of the wall can be used to meet the embedded installation of the embedded invisible telescopic skirting 5. During the specific installation, firstly apply plaster mud or adhesive colloid on the groove wall of the groove or apply plaster mud or adhesive colloid on the embedded invisible telescopic skirting 5, and then press the embedded invisible telescopic skirting 5 into the groove. If necessary, part of the embedded invisible telescopic skirting 5 can be buried in the plaster mud first, and the fifth reference convex strip 51 is exposed outside the groove between the plaster mud and the groove on the wall. Then, the light in the vertical plane projected by the infrared level is used as the light reference. Then, by pressing and knocking the second embedded strip 56 and / or the fifth reference ridge 51, the top surface of the fifth reference ridge 51 is made to coincide with the light reference, so that a very reliable reference can be constructed through the fifth reference ridge 51; and the horizontal light projected by the infrared level meter can be used to adjust the horizontality of the fifth reference ridge 51, so that it is easy to make a wall with very high flatness and verticality, and it can well ensure that the pre-embedded invisible telescopic skirting board 5 is in a straight installation state. The installation of the pre-embedded invisible telescopic skirting board 5 can bring a very good visual perception.

[0123] By grooving, the thickness of the plaster on the wall can be reduced, thereby reducing construction time and construction materials, which in turn helps to improve construction efficiency and reduce construction costs.

[0124] like Fig.11 and Fig.12 As shown, the second embedded strip 56, the fifth reference convex strip 51 and the telescopic pressing strip 57 are all arranged horizontally. This not only facilitates manufacturing, but also facilitates accurate installation of the embedded invisible telescopic skirting 5, which helps to further improve the reliability and applicability of the embedded invisible telescopic skirting 5.

[0125] like Figure 12 to Figure 14As shown, a limiting guide groove 561 is provided on the bottom surface of the second embedded strip 56, and a first limiting convex portion 562 is provided on the groove wall of the limiting guide groove 561. A second limiting convex portion 571 is provided on the side wall of the upper end of the telescopic beading 57. The upper end of the telescopic beading 57 can be vertically slidably embedded in the limiting guide groove 561, and the second limiting convex portion 571 is located directly above the first limiting convex portion 562. By providing the limiting guide groove 561, the telescopic beading 57 can be provided with a very good limiting guiding effect, thereby helping to improve the accuracy and stability of the vertical movement of the telescopic beading 57. By providing the first limiting convex portion 562 and the second limiting convex portion 571, the downward movement range of the telescopic beading 57 can be limited, so as to ensure that the telescopic beading 57 can be stably connected to the second embedded strip 56, so as to avoid the telescopic beading 57 from falling off directly, which helps to further improve the reliability and applicability of the pre-embedded invisible telescopic skirting 5. Moreover, such a limiting structure is also very simple, thereby facilitating the processing of the embedded invisible telescopic skirting 5 .

[0126] like Fig.12 and Fig.14 As shown, the telescopic strip 57 includes a horizontal strip 572 and a limiting strip 573, the limiting strip 573 is arranged horizontally, and one side of the limiting strip 573 is connected to the top surface of the horizontal strip 572, the second limiting protrusion 571 is arranged on the side wall of the limiting strip 573, and the limiting strip 573 can be vertically slidably embedded in the limiting guide groove 561. The structure of the telescopic strip 57 is not only very simple, but also can form a very good contact with the ground and form a seam closing with better visual effect, which helps to further improve the applicability of the embedded invisible telescopic skirting 5.

[0127] like Fig.11 , Fig.12 and Fig.14 As shown, the horizontal strip 572 is arranged in a transverse direction, and the highest position of the front wall of the horizontal strip 572 protruding forward is lower than the highest position of the fifth reference protrusion 51 protruding forward. In this way, the horizontal strip 572 can be prevented from affecting the scraping of the wall surface, thereby facilitating the construction of the wall surface.

[0128] In the actual manufacturing process, the following structure can be adopted: the limiting strip 573 is not tightly embedded in the limiting guide groove 561, and there is a certain friction between it and the limiting guide groove 561, so as to prevent the telescopic pressure strip 57 from falling down by itself through this friction, so that during the ground construction, the telescopic pressure strip 57 can be prevented from affecting the ground construction. This helps to further improve the applicability of the embedded invisible telescopic skirting 5.

[0129] like Fig.11 , Fig.12 and Fig.14As shown, the limiting strip 573 is arranged on the top surface of the rear end of the horizontal strip 572, and the second limiting protrusion 571 is located on the side of the upper end of the limiting strip 573. This can not only form a concave structure with better visual effect, but also avoid the overall height of the embedded invisible telescopic skirting 5 being too large, thereby helping to improve the scope of application.

[0130] like Figures 11 to 13 As shown, the fifth concave-convex portion 52 is located on the front surface of the second embedding strip 56. This can well meet the functions of processing, installation and enhancing positioning strength.

[0131] like Figures 11 to 13 As shown, the thickness of the lower end of the second embedded strip 56 is greater than the thickness of the upper end of the second embedded strip 56. This ensures that the position where the limiting guide groove 561 is opened has a very high structural strength, thereby ensuring that the second embedded strip 56 has a very high structural strength, which helps to further improve the reliability of the pre-embedded invisible telescopic skirting 5. In addition, this can reduce the depth and height of the groove on the wall, and only a groove corresponding to the lower end of the second embedded strip 56 needs to be opened on the wall, which helps to reduce the difficulty of construction.

[0132] like Figures 11 to 13 As shown, the fifth reference convex strip 51 is transversely arranged on the lower side of the outer surface of the second embedded strip 56, the fifth receiving groove 54 is opened to the upper end of the inner surface of the second embedded strip 56, and each fifth through hole 55 is opened on the upper end of the second embedded strip 56. This not only facilitates processing, but also ensures that the pre-embedded invisible telescopic skirting 5 has a very high reliability.

[0133] like Figures 1 to 14 As shown, the embedded ceiling line 1, embedded yang corner line 2, embedded yin corner line 3, embedded leveling strip 4, second embedded strip 56 and telescopic strip 57 are all profile structures. This can facilitate the rapid molding of most of the structures on the embedded ceiling line 1, embedded yang corner line 2, embedded yin corner line 3, embedded leveling strip 4, second embedded strip 56 and telescopic strip 57, and only the through holes cannot be molded together. After the profile molding is completed, the required embedded ceiling line 1, embedded yang corner line 2, embedded yin corner line 3, embedded leveling strip 4, second embedded strip 56 and telescopic strip 57 can be quickly obtained by cutting and opening through holes, which helps to improve the manufacturing efficiency of the square leveling device, and this can also ensure that the square leveling device has high structural strength, thereby helping to further improve the reliability and applicability of the square leveling device.

[0134] The embedded ceiling line 1, embedded external corner line 2, embedded internal corner line 3, embedded leveling strip 4, second embedded strip 56 and telescopic pressure strip 57 are made of aluminum alloy or steel. This ensures that the square leveling device has high structural strength and durability, thereby helping to extend the service life of the square leveling device.

[0135] like Fig.25 and Fig.26 As shown, when the embedded ceiling line 1 is used, a horizontally extending positioning strip 30 is first fixed on the upper side of the wall 20; then plaster 40 is scraped on the wall surface below the positioning strip 30 or plaster 40 is scraped on the first embedding strip 13; then the embedded ceiling line is arranged on the bottom surface of the positioning strip 30, and the first embedding strip 13 is adhered to the wall 20 through the plaster 40; then the first reference convex strip 11 is placed in a virtual vertical plane by pressing; then the first embedding groove 16 is fixed in the first embedding groove 16. Embed kraft paper (not shown) and make the kraft paper cover the lower end of the first embedded strip 13; then scrape plaster on the front side of the first embedded strip 13 and the kraft paper, and use the first reference convex strip 11 as a reference, so that a vertical wall 100 with high flatness and good verticality can be scraped out; after the plaster hardens, arrange the screw 50 in the limit groove 121, and make the threaded end of the screw 50 pass through the limit strip 12 and then be screwed to the positioning strip 30; finally, embed the end of the ceiling panel 60 in the limit groove 121. In this way, the use requirements of the embedded ceiling line can be well met. The installation, placement and use methods of the embedded ceiling line are not limited to the above-mentioned one. In actual use, other installation methods can also be used for installation.

[0136] like Figures 20 to 27As shown, when installing the square leveling device on the wall, first apply the leveling plaster mud to the corresponding position of the wall or to each component of the square leveling device, then press the embedded ceiling line 1 to the upper wall, press the embedded external corner line 2 to the external corner, press the embedded internal corner line 3 to the internal corner, press the embedded leveling strip 4 to the upper middle wall, press the embedded invisible telescopic skirting line 5 to the groove opened on the lower wall, and make the embedded ceiling line 1, embedded external corner line 2, embedded internal corner line 3, embedded leveling strip 4, and embedded invisible telescopic skirting line 5 stick and / or embed on the plaster mud, and also make each reference convex strip exposed outside the plaster mud. Then use the light in the vertical plane projected by the infrared level as the light reference. Then, by pressing and knocking the components and / or the reference ridges of the leveling device, the top surface of each reference ridge coincides with the light reference, which can make each reference ridge located in a virtual vertical plane, so that a very reliable reference can be constructed through each reference ridge, and then these references can be used to scrape out a wall with very high flatness and verticality, which can greatly improve the quality and efficiency of the leveling. When it is necessary to install kraft paper on the components of the leveling device, the kraft paper can be installed on the components of the leveling device in accordance with the above-mentioned method and process of installing kraft paper on the embedded ceiling line 1, so that the installation of kraft paper can be met and the kraft paper can be stably limited. Here only one method of using the leveling device is introduced. In actual use, other installation processes can also be used to install the leveling device.

[0137] When installing the embedded leveling strip 4, the side with the through hole on the embedded ceiling line 1, the side of the embedded external angle line 2 or the side of the embedded internal angle line 3 can be embedded in the fourth embedding groove 43 to press the embedded leveling strip 4 against the inner side of the wall. This can conveniently keep the embedded leveling strip 4 straight, and the through holes on the embedded ceiling line 1, the embedded external angle line 2 or the embedded internal angle line 3 can also facilitate the reference light projected by the infrared level meter to pass through. This can accurately limit the embedded leveling strip 4 and prevent it from deforming during the installation process, and will not affect the adjustment of the embedded leveling strip 4, so it is very convenient to use.
