Description

Technical Field

[0001] This utility model relates to the field of ground edge trim technology, and in particular to a ground edge trim with adjustable height. Background Technology

[0002] In the field of architectural decoration engineering, as people's requirements for the functionality and aesthetics of building spaces continue to increase, ground engineering, as an important component of architectural decoration, receives much attention for its construction quality and decorative effect. Different types of building projects, such as residential buildings, commercial complexes, and office buildings, often exhibit differences in floor level during ground construction due to factors such as building structural design, functional zoning, differences in decoration materials, and construction techniques. Floor levels may also experience differences in level due to construction errors. These differences not only affect the overall aesthetics of the building space but may also pose safety hazards, such as pedestrians tripping over obstacles. Therefore, effective technical means are needed to ensure smooth transitions and connections.

[0003] In handling uneven ground surfaces, edge trims, as key components connecting surfaces of different heights, directly impact the seamless finish. Traditional edge trims often employ a fixed-height design. Because their height is unchangeable, fixed-height edge trims cannot adapt to complex and diverse uneven ground surfaces, resulting in poor connection when the actual height difference exceeds the preset height. Existing adjustable-height edge trims, such as the adjustable-height ceramic tile edge trim disclosed in Chinese Utility Model Patent CN220036004U, achieve height adjustment through the mechanical superposition of combined edge trim embedded parts and accessories. However, they have shortcomings in adjustment method, adjustment range, structural stability, and ease of installation, failing to meet diverse engineering needs. Therefore, developing a flexible, structurally stable, and easy-to-install aluminum alloy edge trim is of great significance for improving the quality of building decoration projects. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing adjustable height ground trim strips, such as inconvenient height adjustment, small adjustment range and lack of flexibility, low structural stability and low installation convenience, and to provide a height-adjustable ground height difference trim strip.

[0005] In a first aspect, this utility model provides a height-adjustable ground level difference trim strip, comprising:

[0006] The trim strip body has a hinged connection at one end and a hinged base at the other end. The base and the trim strip body form an acute angle. A height adjustment part is provided between the base and the trim strip body, and the height adjustment part can linearly adjust the angle between the base and the trim strip body.

[0007] This utility model provides a height-adjustable ground leveling strip. The main body of the strip is hinged at both ends to a connecting portion and a base portion, allowing the strip body to rotate relative to the base and connecting portions, providing a flexible basis for height adjustment. The angle between the base portion and the strip body is acute; for example, the base portion can be folded back towards the connecting portion. This structure not only optimizes the spatial layout but also provides stable support when adjusting the height.

[0008] In use, the height adjustment unit allows for linear adjustment of the angle between the base and the main body of the finishing strip. This enables the finishing strip to rotate around its hinge with the base, facilitating quick and easy adjustment of the vertical height of the joint. This results in continuous and precise height adjustment, with a smoother and more accurate adjustment method. After the height adjustment unit is in place, the joint can be fixedly connected to a higher point on the finished surface (e.g., using expansion bolts), and the base can be fixedly connected to a lower point on the finished surface (e.g., using adhesive). The height adjustment unit, positioned between the base and the finishing strip, not only adjusts the height but also supports the finishing strip, enhancing its stability and reducing the risk of loosening or deformation due to external forces (such as foot traffic).

[0009] Preferably, the height adjustment part includes: a screw, one end of which is hinged to the main body of the closing strip, and the other end of which is threaded to a sleeve.

[0010] With this structural design, the screw and sleeve are connected by a thread, allowing the user to adjust the height of the connection by rotating the sleeve. Because the thread pitch is fixed, each rotation of the sleeve causes the screw to move a fixed amount of displacement axially. This feature enables the user to precisely control the height of the connection, thus meeting the needs of different ground height differences. Whether the ground drop is small or large, a precise fit can be achieved by adjusting the number of rotations.

[0011] The hinged design between the screw and the main body of the trim strip allows the screw to flexibly adapt to changes in the angle of the trim strip, ensuring a smooth adjustment process. The threaded connection between the screw and the sleeve has a self-locking characteristic; after adjustment to the target height, the friction between the threads prevents the screw from accidentally loosening, thus ensuring the stability of the trim strip during use.

[0012] When using it, after determining the height difference between the connecting part and the base part, simply rotate the sleeve to gradually extend the sleeve and abut against the upper surface of the base part to quickly complete the height adjustment of the sealing strip. The operation is simple and efficient.

[0013] Preferably, the height adjustment range is 30mm to 50mm.

[0014] The height adjustment range of the trim is 30mm to 50mm, which can adapt to most common ground height differences in building decoration projects. For example, at the junction of different materials (such as tiles and wood flooring) or in cases of height differences caused by construction errors, this range can meet the general needs while providing sufficient adjustment space for special situations, allowing construction workers to flexibly adjust the height of the trim strip according to the actual site conditions.

[0015] Preferably, a plurality of height adjustment sections are provided along the length extension direction of the main body of the finishing strip.

[0016] This structural design allows multiple height adjustment sections to provide more even support, effectively dispersing external forces (such as foot pressure) and reducing deformation or bending of the main body of the edge trim due to uneven stress. Especially in longer edge trims, multiple adjustment sections ensure the overall structural stability and extend service life.

[0017] Preferably, a plurality of height adjustment portions are evenly distributed along the length extension direction of the main body of the finishing strip.

[0018] Multiple height adjustment sections are evenly distributed along the length of the main body of the edge strip (e.g., spaced 50-150mm apart), which can provide balanced support throughout the entire length range, effectively disperse external forces (such as stepping force or pressure from heavy objects), and avoid deformation or bending caused by uneven local stress.

[0019] Preferably, anti-slip grooves are provided on the outer surfaces of both the main body of the finishing strip and the connecting part.

[0020] Anti-slip grooves effectively prevent pedestrians from slipping by increasing surface friction. This design significantly improves safety, especially on wet or slippery surfaces. For example, in high-traffic areas such as shopping malls, hotel lobbies, or public corridors, anti-slip grooves provide pedestrians with extra grip, reducing the risk of accidental falls.

[0021] Preferably, the connecting part is provided with a limiting strip, which extends from the connecting part toward the ground.

[0022] By setting limit clips, the connection between the joint and the finished surface at a higher point can be more stable, preventing the trim strip from wobbling back and forth due to external forces (such as stepping), and further enhancing the stability of the trim strip.

[0023] Preferably, a cushioning pad is provided on the side of the connecting part facing the ground.

[0024] With this structural design, the cushioning pad is typically made of flexible or elastic materials (such as rubber, silicone, or soft polymers). The cushioning pad absorbs and disperses vibrations generated by pedestrians stepping on the edges or external impacts, reducing direct impact on the joint. This shock absorption effect not only protects the structural integrity of the seam strip but also improves pedestrian comfort.

[0025] Preferably, an anti-slip pad is provided on the side of the base portion facing the height adjustment portion.

[0026] The anti-slip pad is placed on the side of the base facing the height adjustment part. It is usually made of a high coefficient of friction material (such as rubber, silicone or other polymers), which can effectively increase the friction between the base and the height adjustment part. This effectively prevents the two from sliding or shifting relative to each other when subjected to force (such as stepping or vibration), ensuring that the height adjustment part can be stably maintained after being adjusted, and avoiding height changes or structural failures caused by loosening.

[0027] Preferably, the main body of the tapered strip, the connecting part, and the base part are all aluminum alloy structural components.

[0028] Aluminum alloys are characterized by high strength and low density, which allows the main body, connecting parts and base of the edge trim to withstand greater external forces (such as stepping or heavy pressure) while maintaining a lightweight design. This ensures the structural stability of the edge trim, while reducing the overall weight and facilitating transportation and installation.

[0029] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0030] 1. This utility model provides a height-adjustable ground leveling strip. The two ends of the strip body are hinged to a connecting part and a base part, respectively, allowing the strip body to rotate relative to the base part and the connecting part, providing a flexible basis for height adjustment. The height adjustment part can linearly adjust the angle between the base part and the strip body, allowing the strip body to rotate around the hinge point with the base part, thereby conveniently and quickly adjusting the vertical height of the connecting part, achieving continuous and precise height adjustment of the connecting part, and making the adjustment method smoother and more accurate.

[0034] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0035] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use.

[0040] Example 1

[0041] This embodiment provides a height-adjustable ground level difference trim strip, which can be used for, for example... Figure 1 The finished surface of the ground at a higher position shown ( Figure 1 (Middle left) and the lower ground finish surface ( Figure 1 The connection on the right side of the middle.

[0042] This embodiment provides a height-adjustable ground leveling strip, comprising: a strip body 1, a hinged connecting portion 2 at one end of the strip body 1, and a base portion 3 hinged at the other end of the strip body 1. Specifically, in this embodiment, the strip body 1, connecting portion 2, and base portion 3 can all be aluminum alloy structural components. The connecting portion 2 and base portion 3 can be continuous with the strip body 1, for example, the lengths of the strip body 1, connecting portion 2, and base portion 3 can all be 1000mm~1500mm. Aluminum alloy has the characteristics of high strength and low density, which allows the strip body 1, connecting portion 2, and base portion 3 to withstand greater external forces (such as foot pressure or heavy object pressure) while maintaining a lightweight design, ensuring the structural stability of the strip, and reducing the overall weight for easy transportation and installation.

[0043] The angle between the base portion 3 and the main body 1 of the finishing strip is an acute angle, specifically, as shown in... Figure 1 As shown, the base portion 3 can be folded back towards the connecting portion 2, and the angle between the base portion 3 and the finishing strip body 1 is ∠α, where ∠α is an acute angle. The angle between the connecting portion 2 and the finishing strip body 1 is as follows: Figure 1 The angle ∠β shown is an obtuse angle.

[0044] A height adjustment part 4 is provided between the base part 3 and the finishing strip body 1. The height adjustment part 4 can linearly adjust the included angle between the base part 3 and the finishing strip body 1.

[0045] Furthermore, in this embodiment or other embodiments, the height adjustment part 4 includes: a screw 41, one end of which is hinged to the constricting strip body 1, and the other end of which is threaded to the sleeve 42. Specifically, for example... Figure 1As shown, the upper end of the screw 41 can be hinged to the lower surface of the closing strip body 1, and the lower end of the screw 41 is threaded to the sleeve 42.

[0046] With this structural design, the screw 41 and sleeve 42 are connected by a thread, allowing the user to adjust the height of the connecting part 2 by rotating the sleeve 42. Since the thread pitch is fixed, each rotation of the sleeve 42 causes the screw 41 to move axially by a fixed amount. This characteristic allows the user to precisely control the height of the connecting part 2, thus meeting the needs of different ground height differences. Whether it's a small ground drop or a large elevation difference, precise adaptation can be achieved by adjusting the number of rotations.

[0047] The hinged design between the screw 41 and the main body 1 of the tailing strip allows the screw 41 to flexibly adapt to changes in the angle of the main body 1 of the tailing strip, ensuring a smooth adjustment process. The threaded connection between the screw 41 and the sleeve 42 has a self-locking characteristic. After adjustment to the target height, the friction between the threads can prevent the screw 41 from loosening accidentally, thereby ensuring the stability of the tailing strip during use.

[0048] When in use, after determining the height difference between the connecting part 2 and the base part 3, simply rotate the sleeve 42 to gradually extend the sleeve 42 and abut it against the upper surface of the base part 3 (the side of the base part 3 facing the height adjustment part 4) to quickly complete the height adjustment of the sealing strip. The operation is simple and efficient.

[0049] Furthermore, in this embodiment or other embodiments, an anti-slip pad 31 is provided on the side of the base portion 3 facing the height adjustment portion 4. Specifically, as shown... Figure 1 As shown, the sleeve 42 can abut against the anti-slip pad 31, which is located on the side of the base 3 facing the height adjustment part 4. It is usually made of a high coefficient of friction material, such as rubber (natural rubber, nitrile rubber (NBR) or chloroprene rubber (CR)), silicone or other polymers (such as polyurethane (PU)). It can effectively increase the friction between the base 3 and the height adjustment part 4, effectively preventing relative sliding or displacement of the two when subjected to force (such as stepping or vibration), ensuring that the position of the height adjustment part 4 can be stably maintained after adjustment, and avoiding height changes or structural failures caused by loosening.

[0050] Furthermore, in this embodiment or other embodiments, the adjustment range of the height adjustment unit 4 is 30mm to 50mm. Setting the adjustment range of the height adjustment unit 4 to 30mm to 50mm can adapt to most common ground height differences in building decoration projects. For example, at the junction of different materials (such as tiles and wood flooring) or in cases of height differences caused by construction errors, this range not only meets conventional needs but also provides sufficient adjustment space for special situations, allowing construction workers to flexibly adjust the height of the finishing strip according to the actual site conditions.

[0051] Furthermore, in this embodiment or other embodiments, multiple height adjustment parts 4 are provided along the length extension direction of the finishing strip body 1. Specifically, the number of height adjustment parts 4 can be set according to actual needs. Multiple height adjustment parts 4 can provide more uniform support, effectively disperse external forces (such as stepping force), and reduce deformation or bending of the finishing strip body 1 caused by uneven force. Especially in longer finishing strips, multiple adjustment parts ensure the stability of the overall structure and extend service life.

[0052] Furthermore, in this embodiment or other embodiments, multiple height adjustment portions 4 are evenly distributed along the length extension direction of the main body 1 of the finishing strip. The multiple height adjustment portions 4 are evenly distributed along the length direction of the main body 1 of the finishing strip (e.g., arranged at intervals of 50~150mm), which can provide balanced support throughout the entire length range, effectively disperse external forces (such as stepping force or pressure from heavy objects), and avoid deformation or bending caused by uneven local force.

[0053] Furthermore, in this embodiment or other embodiments, anti-slip grooves 5 are formed on the outer surfaces of the main body 1 and the connecting part 2 of the finishing strip. Specifically, the anti-slip grooves 5 can be in the form of straight grooves, and it is foreseeable that the anti-slip grooves 5 can also be other anti-slip forms such as wavy or grid-shaped. The anti-slip grooves 5 effectively prevent pedestrians from slipping while walking by increasing the surface friction. Especially in wet and slippery ground environments, this design significantly improves safety. For example, in high-traffic areas such as shopping malls, hotel lobbies, or public corridors, the anti-slip grooves 5 provide pedestrians with additional grip, reducing the risk of accidental falls.

[0054] Furthermore, in this embodiment or other embodiments, the connecting portion 2 is provided with a limiting strip 21, which extends from the connecting portion 2 toward the ground. Specifically, as shown... Figure 1 As shown, the limiting strip 21 can be a strip-shaped plate that runs the length of the connecting part 2. The limiting strip 21 extends downwards, and its specific position can be located at the hinge joint between the connecting part 2 and the closing strip body 1. The limiting strip 21 is used to... Figure 1 The side wall of the finished surface (higher part) of the ground is in contact with the ground. By setting the limiting strip 21, it can be ensured that the connection between the connecting part 2 and the higher part of the finished surface of the ground is more stable, preventing the finishing strip from shaking back and forth due to external forces (such as stepping), and further enhancing the stability of the finishing strip.

[0055] Furthermore, in this embodiment or other embodiments, a buffer pad 22 is provided on the side of the connecting portion 2 facing the ground. Specifically, for example... Figure 1As shown, the cushioning pad 22 can be installed between the top surface of the finished ground surface (at a higher level) and the connecting part 2. The cushioning pad 22 is typically made of flexible or elastic materials, such as rubber (natural rubber, nitrile rubber (NBR)), silicone, or soft polymers (foamed polyurethane, EVA, etc.). The cushioning pad 22 can absorb and disperse the vibrations generated by pedestrians stepping on it or external impacts, reducing the direct impact on the connecting part 2. This shock absorption effect not only protects the structural integrity of the finishing strip but also improves the comfort of pedestrians.

[0056] This embodiment provides a height-adjustable ground leveling strip. The two ends of the strip body 1 are hinged to a connecting portion 2 and a base portion 3, respectively, allowing the strip body 1 to rotate relative to the base portion 3 and the connecting portion 2, providing a flexible basis for height adjustment. The angle between the base portion 3 and the strip body 1 is acute; for example, the base portion 3 can be folded back towards the connecting portion 2. This structure not only optimizes the spatial layout but also provides stable support when adjusting the height.

[0057] In use, the height adjustment part 4 allows for linear adjustment of the angle between the base part 3 and the finishing strip body 1, enabling the finishing strip body 1 to rotate around the hinge point with the base part 3. This facilitates convenient and quick adjustment of the vertical height of the connecting part 2, achieving continuous and precise height adjustment of the connecting part 2 with a smoother and more accurate adjustment method. After the height adjustment part 4 is adjusted to the correct position, the connecting part 2 can be fixedly connected to a higher part of the finished ground surface (e.g., via expansion screws), and the base part 3 can be fixedly connected to a lower part of the finished ground surface (e.g., via adhesive). The height adjustment part 4, positioned between the base part 3 and the finishing strip body 1, not only adjusts the height but also supports the finishing strip body 1, enhancing the stability of the finishing strip and reducing the risk of loosening or deformation due to external forces (such as stepping).

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
