Description

Technical Field

[0001] This utility model relates to the field of decoration technology, and in particular to a frame for installing decorative panels in elevator lobbies. Background Technology

[0002] In the field of interior design, the elevator lobby, as a key area for people entering and exiting elevators, has a significant impact on the overall architectural image due to its decorative effect. The installation of decorative panels in the elevator lobby is a crucial step in achieving this effect, while the installation frame serves as the basic supporting structure for the panels.

[0003] Traditional elevator lobby decorative panel installation frames typically use a fixed connection method, directly fixing the keel to the wall. However, this fixed frame method has many drawbacks. First, the installation process requires extremely high wall flatness. Any unevenness or construction errors in the wall can easily lead to the keel not being installed horizontally. Tiltped keels directly affect the installation accuracy of the decorative panels, causing gaps and unevenness between panels, affecting not only aesthetics but also potentially leading to loose panels and safety hazards due to weak connections. Second, traditional fixed frames lack flexibility. When horizontal installation is found, it often needs to be dismantled and reinstalled, increasing construction time and costs, and potentially wasting materials. Third, the relatively small space in elevator lobbies makes construction inconvenient, and frequent dismantling and reinstallation further reduces construction efficiency and affects project progress.

[0004] To address the aforementioned issues, there is an urgent need for a frame for installing decorative panels in elevator lobbies that can effectively adapt to wall construction errors and has flexible leveling capabilities, thereby improving the accuracy and efficiency of decorative panel installation and ensuring installation quality and safety. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a frame for installing decorative panels in elevator halls.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] A frame for installing decorative panels in elevator lobbies includes:

[0008] Keel, multiple keels arranged at intervals;

[0009] Two fixing seats are respectively located at both ends of the keel, and the fixing seats are firmly connected to the wall.

[0010] Connecting blocks: Two connecting blocks are installed at both ends of the keel to connect the keel to the fixing base.

[0011] A connecting rod is rotatably connected to one of the fixed seats and to a corresponding connecting block, used to adjust the levelness of the keel; the other fixed seat is rotatably connected to the corresponding connecting block.

[0012] The keel is fastened to the connecting block by self-tapping screws.

[0013] Preferably, the fixing base comprises:

[0014] The fixed plate has hollow studs on its surface, and stepped holes are provided on the fixed plate corresponding to the positions of the hollow studs;

[0015] The adjusting screw sleeve is threadedly connected to the hollow stud and is used to adjust the distance between the keel and the wall; the connecting block can be rotatably connected to the adjusting screw sleeve; or the connecting block can be rotatably connected to one end of the connecting rod, and the other end of the connecting rod can be rotatably connected to the adjusting screw sleeve.

[0016] Preferably, the keel has a groove-shaped structure, the connecting block can be embedded in the groove of the keel, the bottom of the keel groove is provided with a plurality of strip holes spaced apart, and the two groove walls are provided with a plurality of mounting holes for installing self-tapping screws spaced apart.

The fixing seats at both ends of the keel are reliably connected to the wall through fasteners, and the connecting blocks at both ends of the keel and the fixing seats form a stable connection system. One connecting block is rotatably connected to the fixing seat, allowing the angle to be adjusted to adapt to installation deviations. The connecting rod rotatably connected to the other fixing seat can adjust the level of the keel, avoiding gaps and unevenness in the installation of the decorative panels due to the tilt of the keel, and ensuring the stability of the frame system and the installation accuracy of the decorative panels.

[0022] (2) The fixing base of this utility model consists of a fixing plate and an adjusting screw sleeve. The expansion bolt can securely install the fixing plate on the wall. The adjusting screw sleeve is threadedly connected to the hollow stud. By turning the adjusting screw sleeve, the distance between the keel and the wall can be precisely adjusted, providing flexible adjustment space for the installation of decorative panels.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0033] In the description of this utility model, it should be noted that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use. They are only used to facilitate the description of this utility model and to simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0035] Example 1:

[0036] Combined with appendix Figures 1-5 A frame for installing elevator lobby decorative panels includes a keel 1, a fixing base 2, and a connecting block 3. The keel 1 serves as the foundation for the elevator lobby decorative panels, playing a crucial supporting role. During actual installation, multiple keels 1 are arranged at certain intervals. This design provides uniform support points for the elevator lobby decorative panels, greatly facilitating subsequent installation operations and improving overall installation efficiency.

[0037] Structurally, both ends of the keel 1 are equipped with fixing seats 2, which are reliably connected to the wall through fasteners to ensure the stability of the entire frame system. At the same time, connecting blocks 3 are also installed at both ends of the keel 1. These two connecting blocks 3 are used to connect the two ends of the keel 1 to the two fixing seats 2 respectively, forming a stable connection system.

[0038] It should be noted that one of the connecting blocks 3 and the fixed base 2 are rotatably connected, meaning they can only rotate relative to each other and cannot be separated. This design allows for a certain degree of angle adjustment to accommodate minor deviations during installation. The other fixed base 2 is rotatably connected to the connecting rod 4, the other end of which is rotatably connected to the corresponding connecting block 3. By adjusting the length or angle of the connecting rod 4, the levelness of the keel 1 can be effectively adjusted.

[0039] In actual installation scenarios, if the two mounting brackets 2 on the same keel 1 are not installed on the same horizontal line, it may cause the keel 1 to tilt. A tilted keel 1 will directly affect the installation accuracy of the elevator lobby decorative panels, and may even cause gaps or unevenness after installation, thus affecting the overall decorative effect and user experience. Therefore, this adjustable level design has significant practical value, effectively preventing the above problems from occurring.

[0040] During use, installers can first use self-tapping screws 5 to tighten the keel 1 to the connecting block 3 on the fixed base 2, which can be directly rotatably connected. At this point, although the keel 1 is initially fixed, it still retains a certain degree of adjustability. Next, the keel 1 is leveled using a professional leveling tool. After confirming that the keel 1 has reached the ideal level, another self-tapping screw 5 is used to tighten the keel 1 to the connecting block 3 connected to the connecting rod 4, thereby locking the final position of the keel 1 and ensuring that it maintains a stable and reliable level state during subsequent installation and use.

[0041] Example 2:

[0042] Combined with appendix Figures 4-5 A frame for installing decorative panels in elevator lobbies is disclosed, differing from Embodiment 1 in that the design of the fixing base 2 is optimized based on Embodiment 1. The fixing base 2 consists of a fixing plate 2-1 and an adjusting screw sleeve 2-2. A hollow stud is provided on the surface of the fixing plate 2-1, and a stepped hole is opened on the fixing plate 2-1 at a position corresponding to the hollow stud. This design allows expansion bolts to smoothly pass through the hollow stud and through the stepped hole, thereby firmly installing the fixing plate 2-1 on the wall and ensuring the strong connection between the fixing plate 2-1 and the wall.

[0043] The adjusting sleeve 2-2 is connected to the hollow stud by a threaded connection. Its main function is to adjust the distance between the keel 1 and the wall. By turning the adjusting sleeve 2-2, the relative positional relationship between the fixed plate 2-1 and the adjusting sleeve 2-2 can be changed, thereby achieving the purpose of precisely adjusting the distance between the keel 1 and the wall, providing flexible adjustment space for the installation of the elevator hall decorative panel.

[0044] Furthermore, the adjusting screw sleeve 2-2 is designed as a hollow prism structure. This structural feature facilitates easier tightening operations by installers, improves installation efficiency, reduces installation difficulty, and ensures that the adjustment task can be completed quickly and accurately during actual installation.

[0045] The connecting block 3 and the adjusting screw sleeve 2-2 can be rotatably connected, forming a connection structure in which the connecting block 3 is directly rotatably connected to the fixed base 2. It is important to emphasize that the connecting block 3 and the adjusting screw sleeve 2-2 are only allowed to rotate relative to each other, and cannot separate. This design effectively prevents the keel 1 from separating from the fixed base 2, ensuring the stability of the entire frame structure.

[0046] When connecting block 3 is connected to connecting rod 4, one end of connecting block 3 and one end of connecting rod 4 are connected by a rotatable connection, while the other end of connecting rod 4 is rotatably connected to adjusting sleeve 2-2. It should also be noted that the connection relationship between connecting block 3 and connecting rod 4, as well as between connecting rod 4 and adjusting sleeve 2-2, is such that they can only rotate relative to each other and cannot be separated, thereby further enhancing the reliability of the entire skeleton connection system.

[0047] Example 3:

[0048] Based on Figures 6 and 7, a frame for installing decorative panels in elevator lobbies is proposed, which is an improvement on the structure of Embodiment 1 or 2. The keel 1 is designed as a groove structure, and the connecting block 3 can be embedded in the groove of the keel 1. Multiple strip-shaped holes are spaced apart at the bottom of the groove of the keel 1, while multiple mounting holes for installing self-tapping screws 5 are spaced apart on the groove walls on both sides. This design makes the installation process more convenient and faster, improving construction efficiency.

[0049] Furthermore, the keel 1 has inwardly folded edges on both sides of the groove, and the connecting block 3 has corresponding and fitting slots. During installation, the keel 1 and the connecting block 3 can be engaged first, and then the self-tapping screws 5 can be installed. This method not only facilitates the installation of the self-tapping screws 5, but also improves the stability of the installation to a certain extent and reduces possible errors during installation.

[0050] In addition, the connecting block 3 is designed as a hollow structure. This design has two advantages: firstly, it can effectively reduce the installation weight of the connecting block 3 itself, reducing the burden on the entire frame; secondly, the hollow structure can facilitate the installation of the self-tapping screws 5, making the installation process smoother and further improving the convenience of construction.

[0051] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
