Description

Technical Field

[0001] The invention relates to the field of building materials, in particular to a skirting board. Background Art

[0002] At a time when minimalist home decoration is popular, many of our designers and owners, for the sake of aesthetics, will replace the exposed skirtings in their homes with embedded invisible ones. However, there are too many difficulties in implementing the traditional embedded invisible skirtings perfectly.

[0003] 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.

[0004] 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.

[0005] Difficulty 3: The installation process is difficult (for walls that are painted with materials, not including 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 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.

[0006] At the same time, 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 connect them vertically 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 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.

[0007] 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.

[0008] 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.

[0009] In view of the above problems, it is very necessary to design an invisible retractable adjustable skirting to improve the efficiency and quality of house decoration. Summary of the invention

[0010] The purpose of the present invention is to solve the above-mentioned problems and shortcomings, and to provide an invisible telescopic adjustable skirting line, which has an embedded strip, a telescopic pressure strip, and a reference convex strip on the embedded strip, which can simply and conveniently achieve accurate, stable and reliable installation, and achieve a very good invisible installation effect, and can greatly improve the efficiency, flatness and verticality of wall construction. Its installation can bring very good visual perception, and can ensure that the placement of furniture can bring better visual experience, thereby helping to improve the efficiency and quality of house decoration; the use of telescopic pressure strips can not only avoid vertical installation errors It affects the normal function of the invisible telescopic adjustable skirting line, and can also reduce the difficulty of installation and adapt to uneven ground, which can greatly reduce the difficulty of construction; the invisible telescopic adjustable skirting line can be used to adjust and correct the flatness of the wall, and can adapt to uneven ground, and can be adjusted flexibly, which perfectly solves all the pain points encountered during construction. There is no need to worry about the invisible telescopic adjustable skirting line being difficult to install, fix, adjust, and uneven due to uneven walls, non-standard slots, and uneven ground, let alone the time point of the invisible telescopic adjustable skirting line construction intervention. It also greatly improves the construction efficiency on site, improves the construction standards and construction level; the invisible telescopic adjustable skirting line has the advantages of simple structure, convenient manufacturing, low manufacturing cost, high reliability, and good applicability.

[0011] The technical solution of the present invention is achieved in this way:

[0012] The invisible telescopic adjustable skirting line is characterized in that it includes an embedded strip and a telescopic strip, wherein a reference convex strip is arranged on the outer surface of the embedded strip, and the telescopic strip can be vertically telescopically arranged on the bottom surface of the embedded strip; the top surface of the reference convex strip is an arched arc surface; the reference convex strip is a cone structure that is wide inside and narrow outside; a limited guide groove is arranged on the bottom surface of the embedded strip, and a first limited convex portion is arranged on the groove wall of the limited guide groove, and a second limited convex portion is arranged on the side wall of the upper end of the telescopic strip, and the upper end of the telescopic strip can be vertically slidably embedded in the limited guide groove, and the second limited convex portion is located directly above the first limited convex portion; the telescopic strip includes a horizontal strip and a limited strip, and the limited strip is arranged horizontally, and one side edge of the limited strip is connected to the top surface of the horizontal strip, and the second limited convex portion is arranged on the side wall of the limited strip, and the limited strip can be vertically slidable Embedded in the limiting guide groove; the limiting strip is not very tightly embedded in the limiting guide groove, and there is a certain friction between it and the limiting guide groove, so as to prevent the telescopic strip from falling down by itself through this friction; the telescopic strip can be prevented from affecting the ground construction; a storage groove is provided on the inner surface of the embedded strip; a plurality of through holes are provided on the embedded strip; each through hole penetrates the storage groove; a concave-convex part is provided on the outer surface of the embedded strip, and the highest position of the concave-convex part protruding outward is lower than the highest position of the reference convex strip protruding outward; the concave-convex part is connected to the side wall of one side of the reference convex strip, and the distance from the top surface of each convex point of the concave-convex part to the embedded strip is gradually reduced in the direction away from the reference convex strip; it is ensured that the thickness of the gypsum layer away from the reference convex strip is gradually thickened as a whole; at least one embedding groove is provided on the concave-convex part; the embedding groove can be used for embedding kraft paper; each through hole is staggered from the concave-convex part.

[0013] Preferably, the groove wall of the embedding groove is in the shape of the letter C.

[0014] Beneficial effects of the present invention: (1) The invisible telescopic adjustable skirting line of the present invention comprises an embedded strip and a telescopic pressure strip, and a reference convex strip is arranged on the outer surface of the embedded strip, and the telescopic pressure strip is arranged on the bottom surface of the embedded strip in a vertically telescopic manner. By adopting the embedded strip, the requirements for embedded positioning can be achieved, which can facilitate the invisible telescopic adjustable skirting line to be installed in place very stably and reliably, and the reliability of the invisible telescopic adjustable skirting line is very good.

[0015] (2) By vertically telescoping the telescopic strip on the bottom surface of the embedded strip, the telescopic strip can move vertically under the embedded strip, so that when the embedded strip is embedded, the telescopic strip can well form an invisible skirting. The invisible telescopic adjustable skirting has the advantages of stable and firm installation, no falling due to bumps, no dust accumulation on the top, no need to clean the dust on the top, easy cleaning, ensuring the quality of wall decoration, and no influence on the placement of home furnishings against the wall.

[0016] (3) The use of telescopic strips that can be extended vertically can also compensate for vertical installation errors upward or downward to avoid mutual influence between the construction of the wall and the floor. The telescopic strips of the invisible telescopic adjustable skirting can also fit the floor well. Make sure that there is no gap between the telescopic strips and the floor decoration materials after the telescopic strips press the floor decoration materials. Even if the floor is uneven, it will not affect the accurate installation of the invisible telescopic adjustable skirting, nor will it affect the normal use of the invisible telescopic adjustable skirting. The invisible telescopic adjustable skirting has good applicability and can reduce the difficulty of construction.

[0017] (4) The reference convex strip can not only be used as a reference for judging and adjusting the installation position of the invisible telescopic adjustable skirting line, but also provide a very reliable reference line for scraping plaster on the wall. Therefore, the invisible telescopic adjustable skirting line can be installed accurately, stably and reliably in a very simple and convenient way, and a very good invisible installation effect can be achieved, which helps to improve the efficiency, accuracy, straightness and firmness of the installation and positioning of the invisible telescopic adjustable skirting line, so as to ensure that the invisible telescopic adjustable skirting line is in a straight installation state. The installation of the invisible telescopic adjustable skirting line can bring a very good visual experience. When the reference convex strip is used as a reference line for scraping plaster, it can provide a very reliable reference, so that it is convenient for the operator to scrape a flat and straight wall on the wall to avoid the wall from being skewed, which can greatly improve the decoration quality of the wall. The reliability and applicability of the invisible telescopic adjustable skirting line are very good.

[0018] (5) A very accurate and reliable benchmark can be established through the benchmark convex strip, and the accuracy of this benchmark is minimally affected by the workers, which can greatly reduce the error of wall leveling and ensure that the benchmark has a very high flatness and verticality, thereby greatly improving the accuracy of wall leveling construction, and thus making it easy to make a wall with very high flatness and verticality. The invisible telescopic adjustable skirting can greatly improve the quality of wall leveling. When installing the invisible telescopic adjustable skirting, the cumbersome "dotting" operation in the existing rib leveling can be directly omitted, and the wall leveling can be achieved through one construction, and the invisible telescopic adjustable skirting can be perfectly integrated with the wall, so there is no need to rework and repair the connection between the wall and the invisible telescopic adjustable skirting, thereby avoiding damage to the decorative materials on the ground, which can greatly reduce the difficulty of wall leveling, thus helping to improve the efficiency of house decoration.

[0019] (6) By using the reference convex strip as the reference, there will be no problem of roughness like the ribs produced by punching. In addition, the reference convex strip is in the shape of a strip, which can greatly reduce the friction between the ruler and the reference convex strip during filling and leveling, thereby greatly reducing the resistance of the ruler to scraping, and then making it easier to scrape and level quickly, which also helps to improve the efficiency and quality of wall leveling. The invisible telescopic adjustable skirting 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.

[0020] (7) The invisible retractable and adjustable skirting can easily create a wall with very high flatness and verticality, so that when the furniture is placed against the wall, there will be no gap between the furniture and the wall, so that the wall will not appear uneven or tilted, and the furniture will not appear tilted, which can bring a better visual experience and greatly improve the grade of the house. And when there is no gap between the furniture and the wall, mosquitoes, dust, debris, etc. 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.

[0021] (8) The invisible telescopic adjustable skirting can be used to adjust and correct the flatness of the wall, and can adapt to the uneven ground and can be adjusted. It perfectly solves all the pain points encountered during construction. There is no need to worry about the invisible telescopic adjustable skirting being difficult to install, fix, adjust, or uneven due to uneven walls, non-standard grooves, and uneven ground. There is no need to worry about the time point for the construction of the invisible telescopic adjustable skirting. It also greatly improves the construction efficiency on site and improves the construction standards and level.

[0022] (9) The overall structure of the invisible telescopic adjustable skirting board is very simple, and it also has the advantages of low manufacturing difficulty and low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figure 1 and Figure 2 As shown, the invisible telescopic adjustable skirting board of the present invention comprises an embedded strip 1 and a telescopic pressure strip 2, wherein a reference convex strip 11 is arranged on the outer surface of the embedded strip 1, and the telescopic pressure strip 2 can be arranged on the bottom surface of the embedded strip 1 in a vertically telescopic manner.

[0028] The invisible telescopic adjustable skirting line of the present invention comprises an embedded strip 1 and a telescopic pressure strip 2, and a reference convex strip 11 is arranged on the outer surface of the embedded strip 1, and the telescopic pressure strip 2 is arranged on the bottom surface of the embedded strip 1 in a vertically telescopic manner. By adopting the embedded strip 1, the requirement of embedded positioning can be achieved, which can facilitate the invisible telescopic adjustable skirting line to be installed in place very stably and reliably, and the reliability of the invisible telescopic adjustable skirting line is very good.

[0029] By vertically telescopically arranging the telescopic bead 2 on the bottom surface of the embedded strip 1, the telescopic bead 2 can move vertically below the embedded strip 1, so that when the embedded strip 1 is embedded, the telescopic bead 2 can well form an invisible skirting. The invisible telescopic adjustable skirting has the advantages of stable and firm installation, no falling due to bumps, no accumulation of dust on the top, no need to clean the dust on the top, easy cleaning, ensuring the quality of wall decoration, and no influence on the placement of home furnishings against the wall.

[0030] The use of a telescopic strip 2 that can be telescopically extended vertically can also compensate 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 invisible telescopic adjustable skirting line 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 invisible telescopic adjustable skirting line, nor will it affect the normal use of the invisible telescopic adjustable skirting line. The invisible telescopic adjustable skirting line has good applicability and can reduce the difficulty of construction.

[0031] The reference convex strip 11 can not only be used as a reference for judging and adjusting the installation position of the invisible telescopic adjustable skirting, but also provide a very reliable reference line for scraping plaster on the wall. Therefore, the invisible telescopic adjustable skirting can be installed accurately, stably and reliably in place very simply and conveniently, and a very good invisible installation effect can be achieved, which helps to improve the efficiency, accuracy, straightness and firmness of the installation and positioning of the invisible telescopic adjustable skirting, so as to well ensure that the invisible telescopic adjustable skirting is in a straight installation state, and the installation of the invisible telescopic adjustable skirting can bring a very good visual sense. When the reference convex strip 11 is used as a reference line for plaster scraping, it can provide a very reliable reference, so that it is convenient for the operator to scrape a flat and straight wall on the wall to avoid the wall from being skewed, which can greatly improve the decoration quality of the wall, and the reliability and applicability of the invisible telescopic adjustable skirting are very good.

[0032] A very accurate and reliable benchmark can be established through the benchmark convex strip 11, and the accuracy of this benchmark is minimally affected by the workers, which can greatly reduce the error of wall leveling and ensure that the benchmark has a very high flatness and verticality, thereby greatly improving the accuracy of wall leveling construction, and then it is easy to make a wall with very high flatness and verticality. The invisible telescopic adjustable skirting can greatly improve the quality of wall leveling. When installing the invisible telescopic adjustable skirting, the cumbersome "dotting" operation in the existing rib leveling can be directly omitted, and the wall leveling can be achieved through one construction, and the invisible telescopic adjustable skirting can be perfectly integrated with the wall, so there is no need to rework and repair the connection between the wall and the invisible telescopic adjustable skirting, thereby avoiding damage to the decorative materials on the ground, which can greatly reduce the difficulty of wall leveling, which helps to improve the efficiency of house decoration.

[0033] By using the reference convex strip 11 as the reference, there will be no problem of roughness like the ribs produced by punching. In addition, the reference convex strip 11 is in the shape of a strip, which can greatly reduce the friction between the ruler and the reference convex strip 11 during filling and leveling, thereby greatly reducing the resistance of the ruler to scraping, and thus making it easier to scrape and level quickly, which also helps to improve the efficiency and quality of wall leveling. The invisible telescopic adjustable skirting 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.

[0034] The invisible retractable and adjustable skirting can easily create a wall with very high flatness and verticality, so that when the furniture is placed against the wall, there will be no gap between the furniture and the wall, so that the wall will not appear uneven or tilted, and the furniture will not appear tilted, which can bring a better visual experience and greatly improve the grade of the house. And when there is no gap between the furniture and the wall, mosquitoes, dust, debris, etc. 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 indoor hygiene can still be guaranteed, which helps to improve the convenience of indoor cleaning.

[0035] The invisible telescopic adjustable skirting can be used to adjust and correct the flatness of the wall, and can adapt to the uneven ground and can be adjusted telescopically. It perfectly solves all the pain points encountered during construction. There is no need to worry about the invisible telescopic adjustable skirting being difficult to install, fix, adjust, or uneven due to uneven walls, non-standard slots, and uneven ground. There is no need to worry about the time point for the construction of the invisible telescopic adjustable skirting. It also greatly improves the construction efficiency on site, and improves the construction standards and construction level.

[0036] Moreover, the overall structure of the invisible telescopic adjustable skirting board is very simple, and it also has the advantages of low manufacturing difficulty and low manufacturing cost.

[0037] When installing the invisible telescopic adjustable skirting, several other leveling strips with reference convex strips can be embedded in the wall. In this way, a very reliable reference surface can be established by making the reference convex strip 11 on the invisible telescopic adjustable skirting and other reference convex strips in the same vertical plane. When filling the gypsum mud, the gypsum mud can be scraped based on this reference surface, so that the wall surface with very high flatness and verticality can be scraped.

[0038] When installing the invisible telescopic adjustable skirting, the recessed installation of the invisible telescopic adjustable skirting can be achieved by making a groove on the lower side of the wall. During the specific installation, first apply plaster mud (or adhesive colloid) on the groove wall of the groove or apply plaster mud (or adhesive colloid) on the invisible telescopic adjustable skirting, and then press the invisible telescopic adjustable skirting into the groove (if necessary, part of the invisible telescopic adjustable skirting can be buried in the plaster mud first), and expose the reference convex strip 11 outside the groove between the plaster mud and the groove on the wall. Then use the light in the vertical plane projected by the infrared level as the light reference. Then, by pressing and knocking the embedded strip 1 and / or the reference convex strip 11, the top surface of the reference convex strip 11 is made to coincide with the light reference, so that a very reliable reference can be constructed through the reference convex strip 11; and the horizontal light projected by the infrared level can be used to adjust the horizontality of the reference convex strip 11, so that it is easy to make a wall with very high flatness and verticality, and it can well ensure that the invisible telescopic adjustable skirting line is in a straight installation state. The installation of the invisible telescopic adjustable skirting line can bring a very good visual perception.

[0039] 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.

[0040] like Figure 1 and Figure 2 As shown, the embedded strip 1, the reference convex strip 11 and the telescopic pressure strip 2 are all arranged horizontally. This not only facilitates manufacturing, but also facilitates accurate installation of the invisible telescopic adjustable skirting, which helps to further improve the reliability and applicability of the invisible telescopic adjustable skirting.

[0041] like Figure 3 As shown, the top surface of the reference convex strip 11 is an arched arc surface 111. This not only serves as a very good reference, but also reduces the resistance of plaster scraping on the reference convex strip 11, so as to facilitate the workers to scrape the plaster at the reference convex strip 11, thereby ensuring that the plaster scraping can be carried out very smoothly, and then it is convenient to improve the efficiency of wall decoration, which helps to further improve the applicability of the invisible telescopic adjustable skirting.

[0042] like Figure 3As shown, the reference convex strip 11 is a cone structure with a wide inner side and a narrow outer side, which is not only convenient for decoration, but also ensures that the reference convex strip 11 has a high structural strength, thereby helping to improve the reliability and applicability of the invisible telescopic adjustable skirting.

[0043] like Figures 1 to 4 As shown, a limiting guide groove 12 is provided on the bottom surface of the embedded strip 1, and a first limiting convex portion 121 is provided on the groove wall of the limiting guide groove 12, and a second limiting convex portion 21 is provided on the side wall of the upper end of the telescopic beading 2, and the upper end of the telescopic beading 2 can be vertically slidably embedded in the limiting guide groove 12, and the second limiting convex portion 21 is located directly above the first limiting convex portion 121. By providing the limiting guide groove 12, a very good limiting guiding effect can be played on the telescopic beading 2, thereby helping to improve the accuracy and stability of the vertical movement of the telescopic beading 2. By providing the first limiting convex portion 121 and the second limiting convex portion 21, the purpose of limiting the downward movement range of the telescopic beading 2 can be achieved, so as to ensure that the telescopic beading 2 can be stably connected to the embedded strip 1, so as to avoid the telescopic beading 2 from falling off directly, which helps to further improve the reliability and applicability of the invisible telescopic adjustable skirting. And such a limiting structure is also very simple, so that the processing of the invisible telescopic adjustable skirting can be convenient.

[0044] like Figure 1 , Figure 2 and Figure 4 As shown, the telescopic strip 2 includes a horizontal strip 22 and a limiting strip 23, the limiting strip 23 is arranged horizontally, and one side of the limiting strip 23 is connected to the top surface of the horizontal strip 22, the second limiting protrusion 21 is arranged on the side wall of the limiting strip 23, and the limiting strip 23 can be vertically slidably embedded in the limiting guide groove 12. The structure of the telescopic strip 2 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 invisible telescopic adjustable skirting.

[0045] like Figure 2 and Figure 4 As shown, the horizontal strips 22 are arranged horizontally, and the highest position of the front wall of the horizontal strips 22 protruding forward is lower than the highest position of the reference convex strips 11 protruding forward. In this way, the horizontal strips 22 can be prevented from affecting the scraping of the wall, thereby facilitating the construction of the wall.

[0046] In the actual manufacturing process, the following structure can be adopted: the limiting strip 23 is not tightly embedded in the limiting guide groove 12, and there is a certain friction between it and the limiting guide groove 12, so as to prevent the telescopic layer 2 from falling down by itself through this friction, so that during the ground construction, the telescopic layer 2 can be prevented from affecting the ground construction. This helps to further improve the applicability of the invisible telescopic adjustable skirting.

[0047] like Figure 4 As shown, the limiting strip 23 is arranged on the top surface of the rear end of the horizontal strip 22, and the second limiting protrusion 21 is located on the side of the upper end of the limiting strip 23. This not only forms a concave structure with better visual effect, but also avoids the overall height of the invisible telescopic adjustable skirting being too large, thereby helping to improve the scope of application.

[0048] like Figure 3 As shown, a storage groove 13 is provided on the inner surface of the embedding strip 1. By providing the storage groove 13 on the inner surface of the embedding strip 1, plaster or glue can be stored inside the embedding strip 1, so as to ensure that there is sufficient plaster or glue between the invisible telescopic adjustable skirting and the wall, thereby ensuring that the invisible telescopic adjustable skirting can be installed on the wall very stably, which helps to further improve the reliability of the invisible telescopic adjustable skirting.

[0049] like Figure 1 and Figure 3 As shown, the embedded strip 1 is provided with a plurality of through holes 14. When installing the invisible telescopic adjustable skirting, the through holes 14 can facilitate the discharge of excess plaster or glue on the inside of the invisible telescopic adjustable skirting, thereby avoiding excessive plaster or glue on the inside of the invisible telescopic adjustable skirting, and then facilitating the quick fixation of the invisible telescopic adjustable skirting, which helps to further improve the installation efficiency of the invisible telescopic adjustable skirting. The through holes 14 can also facilitate the setting of plaster or glue running through the invisible telescopic adjustable skirting, thereby facilitating the more stable fixation of the invisible telescopic adjustable skirting on the wall, and then helping to further improve the stability and reliability of the installation and positioning of the invisible telescopic adjustable skirting.

[0050] like Figure 1 As shown, the through holes 14 are arranged side by side along the length direction of the embedding bar 1. This not only facilitates the formation of a reliable embedding bar 1, but also reduces the influence of the through holes 14 on the structural strength of the embedding bar 1, thereby ensuring that the embedding bar 1 has high reliability.

[0051] like Figure 3 As shown, each through hole 14 passes through the storage groove 13. This makes it easier to discharge excess plaster or glue, and can further enhance the reliability and stability of the plaster or glue fixing embedded strip 1, thereby helping to further improve the reliability and applicability of the invisible telescopic adjustable skirting.

[0052] like Figure 2 and Figure 3As shown, a concavoconvex portion 15 is provided on the outer surface of the embedding strip 1, and the highest position of the concavoconvex portion 15 protruding outward is lower than the highest position of the reference convex strip 11 protruding outward. By providing the concavoconvex portion 15, the adhesion ability of the invisible telescopic adjustable skirting line to the gypsum can be improved, so that the invisible telescopic adjustable skirting line can be buried in the wall very stably, and then the gypsum can be stably attached to the invisible telescopic adjustable skirting line, which can greatly reduce the probability of cracking and falling off of the gypsum, which can facilitate the construction of a very reliable wall surface. The concavoconvex portion 15 can also enhance the structural strength of the invisible telescopic adjustable skirting line. This helps to further improve the reliability of the invisible telescopic adjustable skirting line.

[0053] like Figure 2 and Figure 3 As shown, the concavoconvex part 15 is connected to the side wall of one side of the reference convex strip 11, and the distance from the top surface of each convex point 151 of the concavoconvex part 15 to the embedded strip 1 is gradually reduced in the direction away from the reference convex strip 11. This can not only enhance the reliability and stability of the connection between the reference convex strip 11 and the embedded strip 1, but also improve the reliability and stability of the concavoconvex part 15, thereby helping to improve the structural strength of the invisible telescopic adjustable skirting, and further helping to further improve the reliability of the invisible telescopic adjustable skirting. By adopting the concavoconvex part 15 with the above thickness structure, it can be ensured that the thickness of the gypsum layer away from the reference convex strip 11 is gradually thickened overall, and the concavoconvex part 15 itself facilitates the stable attachment of the gypsum, which can effectively improve the stability and reliability of the gypsum attachment to avoid the gypsum from falling off, thereby helping to further improve the reliability and applicability of the invisible telescopic adjustable skirting.

[0054] like Figure 1 and Figure 3 As shown, each through hole 14 is staggered with the concave-convex part 15. In this way, the invisible telescopic adjustable skirting line can be easily ensured to have a high structural strength through the concave-convex part 15, and the through hole 14 can be prevented from affecting the structural strength of the invisible telescopic adjustable skirting line, thereby ensuring that the invisible telescopic adjustable skirting line has high reliability.

[0055] like Figures 1 to 3 As shown, the concave-convex part 15 is wavy. The structure of the concave-convex part 15 is very simple and reliable, so it can be conveniently formed in one piece, thereby helping to further improve the convenience of manufacturing the invisible telescopic adjustable skirting.

[0056] like Figure 2 and Figure 3As shown, at least one embedding groove 16 is provided on the concave-convex part 15. The embedding groove 16 can be used for embedding kraft paper, so that the kraft paper can be stably and accurately positioned on the invisible telescopic adjustable skirting, so that a more gentle transition can be formed between the invisible telescopic adjustable skirting and the gypsum, and the invisible telescopic adjustable skirting can be more reliably connected to the gypsum, which helps to further improve the reliability of the invisible telescopic adjustable skirting. In addition, this can reduce the impact of thermal expansion and contraction and collision on the invisible telescopic adjustable skirting, so as to avoid cracking of the gypsum at the side of the invisible telescopic adjustable skirting in these cases, so as to ensure that the wall surface maintains a good decorative effect for a long time, which helps to further improve the reliability and applicability of the invisible telescopic adjustable skirting. By providing the embedding groove 16 on the concave-convex portion 15, it can not only reduce the impact on the structural strength of the embedded strip 1, but also make it easier for the kraft paper to be pasted on the concave-convex portion 15, which can facilitate the limiting effect of the kraft paper through the concave-convex portion 15, thereby facilitating the improvement of the reliability of the installation and positioning of the kraft paper, and further ensuring that the invisible telescopic adjustable skirting board has a very high reliability.

[0057] like Figure 2 and Figure 3 As shown, the embedding groove 16 is a strip groove, and the two ends of the embedding groove 16 are respectively penetrated to the two end surfaces of the embedding strip 1. This can not only facilitate the formation of a more reliable embedding effect, but also facilitate the manufacturing and processing of the embedding groove 16.

[0058] like Figure 2 and Figure 3 As shown, the concave-convex part 15 is provided with two embedding grooves 16, one large and one small. This can easily meet the requirements of kraft paper with different thicknesses and different installation positions, thereby meeting more usage requirements, and further helping to further improve the applicability of the invisible telescopic adjustable skirting.

[0059] like Figure 2 and Figure 3 As shown, the groove wall of the embedding groove 16 is in the shape of the letter C. In this way, the embedding groove 16 can have a better limiting effect, which helps to improve the stability and reliability of the kraft paper embedding, thereby helping to further improve the reliability of the invisible telescopic adjustable skirting.

[0060] like Figure 2 and Figure 3 As shown, during installation, the lower end of the kraft paper is embedded in the embedding groove 16, and the upper end of the kraft paper is away from the reference convex strip 11, and the kraft paper is also covered on the upper side of the invisible telescopic adjustable skirting line. This can meet the installation requirements.

[0061] like Figure 2 and Figure 3As shown, the storage groove 13 penetrates the upper side wall of the embedded strip 1. This makes it easy for excess plaster or glue to be discharged from the inner side of the invisible telescopic adjustable skirting line to avoid affecting the normal installation and positioning of the invisible telescopic adjustable skirting line, which makes it easy to install the invisible telescopic adjustable skirting line more quickly, thereby helping to further improve the convenience and accuracy of the installation and positioning of the invisible telescopic adjustable skirting line.

[0062] Before installation, first brush plaster or glue on part of the wall; then stick the invisible telescopic adjustable skirting line on the plaster or glue, and squeeze the invisible telescopic adjustable skirting line inwards, so that the excess plaster or glue will be squeezed out from the inside of the invisible telescopic adjustable skirting line.

[0063] like Figure 2 and Figure 3 As shown, the storage groove 13 also penetrates the end surfaces of both ends of the embedding strip 1. This not only facilitates the storage of more plaster or glue, but also facilitates the molding of the storage groove 13, thereby facilitating the convenience of manufacturing.

[0064] like Figures 1 to 4 As shown, the embedded strip 1 and the telescopic strip 2 are both profile structures. This makes it easy to quickly mold the entire structure of the telescopic strip 2 and most of the structure of the embedded strip 1, and only the through hole 14 cannot be molded together. After the molding of the two profiles is completed, the telescopic strip 2 can be quickly obtained by cutting the profile corresponding to the telescopic strip 2. By cutting the profile corresponding to the embedded strip 1, the embedded strip 1 without the through hole 14 can be quickly obtained, and then the required embedded strip 1 can be quickly obtained by opening the through hole 14. Finally, the invisible telescopic adjustable skirting line can be obtained by assembling the embedded strip 1 and the telescopic strip 2, which helps to improve the manufacturing efficiency of the invisible telescopic adjustable skirting line, and this can also ensure that the invisible telescopic adjustable skirting line has a high structural strength, thereby helping to further improve the reliability and applicability of the invisible telescopic adjustable skirting line.

[0065] The embedded strip 1 and the telescopic strip 2 are made of aluminum alloy or steel, which can ensure that the embedded strip 1 and the telescopic strip 2 have high structural strength and durability, thereby helping to extend the service life of the invisible telescopic adjustable skirting.

[0066] like Figure 2 and Figure 3 As shown, the thickness of the lower end of the embedding strip 1 is greater than the thickness of the upper end of the embedding strip 1. This ensures that the position-limiting guide groove 12 has a very high structural strength, thereby ensuring that the embedding strip 1 has a very high structural strength, which helps to further improve the reliability of the invisible telescopic adjustable skirting. 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 embedding strip 1 needs to be opened on the wall, which helps to reduce the difficulty of construction.

[0067] like Figures 1 to 3 As shown, the reference convex strip 11 is transversely arranged on the lower side of the outer surface of the embedded strip 1, the storage groove 13 is opened to the upper end of the inner surface of the embedded strip 1, and each through hole 14 is opened on the upper end of the embedded strip 1. This not only facilitates processing, but also ensures that the invisible telescopic adjustable skirting has a very high reliability.

[0068] The above embodiments are preferred embodiments of the present invention. All structures similar to the present invention and equivalent changes made thereto should fall within the protection scope of the present invention.
