Description

Technical Field

[0001] This utility model belongs to the field of building decoration and renovation technology, and specifically refers to an interior decoration and renovation frame structure. Background Technology

[0002] Interior decoration and renovation frameworks play a crucial role in the creation of modern architectural interior spaces. They not only provide a stable supporting structure for various decorative panels, significantly influencing the overall layout and style of the interior space, but also, to a certain extent, ensure the safety and durability of the interior decoration. They are widely used in decoration projects for various interior environments, including residential, commercial, and office spaces.

[0003] In existing interior decoration and renovation technologies, traditional frame structures have many inconveniences. For example, the installation of decorative panels mainly relies on traditional methods such as adhesive bonding, screw fixing, or simple clips, which have significant drawbacks: adhesive fixing requires curing time and is difficult to disassemble, easily staining the panels and walls; screw installation requires special tools, is cumbersome, and can easily damage materials; while single-point clip structures simplify installation, their locking strength is insufficient, making them prone to falling off due to vibration. Furthermore, panel splicing often relies on manual alignment, easily creating gaps or misalignments, affecting the overall aesthetics. These methods not only prolong the construction period but also increase the difficulty of later maintenance, failing to meet the demands of modern decoration projects for efficiency, flexibility, and reusable assembly and disassembly. Therefore, a new frame structure is urgently needed to overcome the limitations of existing technologies. Utility Model Content

[0004] This invention utilizes a dual fixing mechanism consisting of a retaining plate for initial positioning and a mechanical locking buckle, enabling tool-free rapid installation and disassembly, significantly improving construction efficiency. This alleviates the problems mentioned in the background section.

[0005] The purpose of this utility model is achieved as follows: an interior decoration and renovation frame structure, comprising:

[0006] The mounting frame includes multiple horizontal supports fixed to the wall and multiple vertical supports that enclose the two ends of each horizontal support to form multiple mounting chambers. Each mounting chamber has inwardly extending locking slots on its upper and lower sides, and the grooves of the locking slots form locking channels.

[0007] Multiple panels, with a retaining plate at the rear of the panel that is initially positioned with a locking channel on one side, and symmetrically arranged mounting seats at the rear of the panel. The mounting seats are equipped with locking levers that engage with the locking channel on the other side, and a linkage mechanism for controlling the retraction of the locking levers to release the lock.

[0008] A connector is provided on one side of the panel in the horizontal direction, and a plug interface adapted to the connector is provided on the other side of the panel in the horizontal direction. The connector and plug interface are used for the horizontal splicing of the panel.

[0009] The present invention is further configured such that the extension and retraction direction of the locking lever is parallel to the panel plane in the locked state, and the end of the locking lever is adapted to the locking channel.

[0010] The present invention is further configured such that the locking slot block is provided with multiple locking holes for forming a multi-point locking with the locking lever.

[0011] The present invention is further configured such that the linkage mechanism includes:

[0012] A return spring is located inside the mounting base and is connected to the bottom of the locking lever;

[0013] A drive rod is connected to the bottom of the locking lever. The drive rod is used to pull the locking lever back by a return spring to release the engagement with the locking channel.

[0014] The present invention is further configured such that the cross-section of the connector is trapezoidal, and the insertion interface is a groove corresponding to the trapezoid, forming a seamless splicing surface after insertion.

[0015] The present invention is further provided with an elastic buffer layer on the contact surface between the retaining plate and the locking channel to absorb the impact vibration during panel installation.

[0016] The present invention is further provided that the left and right sides of the mounting chamber are provided with mating structures corresponding to the insertion interfaces and connectors on the panel, and the mating structures are used to assist in the horizontal alignment of the panel.

[0017] The present invention is further configured such that the surface of the locking lever is provided with a polytetrafluoroethylene self-lubricating coating, and the inner wall of the locking channel is embedded with a nylon wear-resistant pad.

[0018] The present invention is further configured such that the number of horizontal supports is three, including:

[0019] The side bracket is located on the upper and lower sides of the wall. The side bracket facing the installation chamber has a side receiving groove for engaging the bottom or top of the corresponding panel.

[0020] The center bracket is located between the two side brackets. The center bracket has a center receiving groove on both the upper and lower sides, which is used to engage the bottom of the upper panel and the top of the lower panel, respectively.

[0021] By adopting the above technical solution, the beneficial effects that this utility model can achieve are:

[0022] 1. By using the locking slot on the mounting frame to cooperate with the retaining plate and locking lever at the back of the panel, the retaining plate is initially positioned with the locking channel on one side during installation, and then the locking lever is used to engage with the locking channel on the other side. This eliminates the need for complicated tools and cumbersome operating steps, simplifying the panel installation process and improving installation efficiency.

[0023] 2. When locked, the extension and retraction direction of the locking lever is parallel to the panel plane and its end is adapted to the locking channel. Together with the multiple locking holes on the locking slot, it forms a multi-point locking, which can effectively prevent the panel from loosening or shifting, and enhance the stability of the connection between the frame structure and the panel.

[0024] 3. The reset spring in the linkage mechanism works with the drive rod. When it is necessary to remove the panel, pull the drive rod to retract the locking lever through the reset spring, which can release the engagement with the locking channel, making it convenient to replace and repair individual panels and reducing the difficulty of later maintenance.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-5 :

[0032] Example 1:

[0033] This embodiment provides an interior decoration and renovation frame structure, including:

[0034] The mounting frame 1 includes multiple horizontal supports 100 fixed to the wall, and a vertical support 101 that surrounds the two ends of each horizontal support 100 to form multiple mounting chambers 102. Each mounting chamber 102 has inwardly extending locking grooves 2 on its upper and lower sides, and the groove of the locking groove 2 forms a locking channel 3.

[0035] Multiple panels 4, with a retaining plate 5 at the rear of the panel 4 that is initially positioned with a locking channel 3 on one side, and a symmetrically arranged mounting base 6 at the rear of the panel 4. The mounting base 6 is provided with a locking lever 7 that engages with the locking channel 3 on the other side, and a linkage mechanism 8 for controlling the locking lever 7 to retract to release the lock.

[0036] A connector 9 is provided on one side of the panel 4 in the horizontal direction, and a plug interface 10 adapted to the connector 9 is provided on the other side of the panel 4 in the horizontal direction. The connector 9 and the plug interface 10 are used for the horizontal splicing of the panel 4.

[0037] The horizontal bracket 100 is fixed to the wall and, together with the vertical bracket 101, forms the mounting frame 1, providing horizontal support and positioning for the panel 4. The horizontal bracket 100 bears the weight of the panel 4, ensuring that the panel 4 is installed in a horizontal position and keeping the entire decorative surface flat. The horizontal bracket 100 is typically a rectangular strip structure and can be fixedly connected to the wall using bolts, expansion screws, or other connectors.

[0038] The vertical bracket 101 and the horizontal bracket 100 enclose an installation chamber 102, providing vertical positioning and support for the panel 4, while also enhancing the overall stability of the installation frame 1. The vertical bracket 101 defines the boundary of the installation chamber 102, ensuring accurate vertical installation of the panel 4 and guaranteeing the verticality of the decorative surface. The vertical bracket 101 is also a rectangular strip structure, similar to the horizontal bracket 100, but its installation direction is perpendicular to the wall. The vertical bracket 101 and the horizontal bracket 100 can be fixed together by welding, bolting, or clamping.

[0039] Locking slots 2 are located on the upper and lower sides of the mounting chamber 102. Their recessed portions form locking channels 3, which cooperate with the retaining plate 5 and locking lever 7 on the panel 4 to achieve positioning and locking of the panel 4. Locking slots 2 are typically block-shaped structures with inwardly extending grooves. Locking slots 2 can be integrally formed with the horizontal bracket 100, or fixed to the horizontal bracket 100 by welding, bolting, or other methods.

[0040] Panel 4, as a surface component for interior decoration, is used to cover walls, providing an aesthetically pleasing decorative effect while protecting the walls. Panel 4 is typically a rectangular flat panel structure, with various components at the rear for connection to the frame, such as retaining plate 5 and mounting base 6. Panel 4 is installed within the mounting chamber 102 formed by horizontal brackets 100 and vertical brackets 101, covering the wall surface. Panel 4 can be connected to the locking slot 2 of the mounting frame 1 via the retaining plate 5, locking lever 7, and other components at the rear, and can also be laterally spliced ​​with adjacent panels 4 via connectors 9 and interfaces 10.

[0041] During the installation of panel 4, retaining plate 5 provides initial positioning between panel 4 and mounting frame 1, ensuring the stability of panel 4 during installation. Retaining plate 5 prevents panel 4 from shaking or shifting during initial installation, providing an accurate starting position for subsequent locking operations. Retaining plate 5 is typically a flat plate structure; one end can be fixed to the rear of panel 4 by welding or bolts, while the other end engages with the locking channel 3 on one side.

[0042] Mounting base 6 is used to mount locking lever 7 and linkage mechanism 8, providing support and connection points for locking panel 4 to mounting frame 1. Mounting base 6 is typically a rectangular or square block structure with internal space to accommodate locking lever 7 and linkage mechanism 8. Mounting base 6 is symmetrically arranged at the rear of panel 4, corresponding to locking channel 3 on locking slot block 2. Mounting base 6 can be fixedly connected to the rear of panel 4 by bolts or welding.

[0043] The locking lever 7 engages with the locking channel 3 on the locking slot 2, locking the panel 4 to the mounting frame 1 and preventing the panel 4 from falling off. The locking lever 7 is usually a rod-shaped structure, which is movably connected to the mounting base 6 and can move telescopically within the mounting base 6. It is also connected to the linkage mechanism 8, which controls its telescopic movement.

[0044] The linkage mechanism 8 is used to control the extension and retraction of the locking lever 7, thereby enabling the locking and unlocking operations of the panel 4.

[0045] The connector 9 and the interface 10 are used to achieve horizontal splicing of the panels 4, forming a seamless connection between adjacent panels 4, improving the decorative effect and overall stability. The connector 9 is a protruding block structure, which can be rectangular or circular in shape, and the interface 10 is a groove of a corresponding shape. The connector 9 and the interface 10 are located on both sides of the panel 4 in the horizontal direction, respectively. They achieve the connection between adjacent panels 4 in the horizontal direction through insertion and mating. After the connector 9 is inserted into the interface 10, a tight splicing surface is formed.

[0046] Example 2:

[0047] This embodiment provides an interior decoration and renovation frame structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0048] The extension and retraction direction of the locking lever 7 is parallel to the plane of the panel 4 in the locked state, and the end of the locking lever 7 is adapted to the locking channel 3.

[0049] In this embodiment, the extension direction of the locking lever 7 is parallel to the plane of the panel 4 in the locked state, and its end is adapted to the locking channel 3. This design serves multiple purposes. From the perspective of ease of installation, the extension direction parallel to the plane of the panel 4 allows the locking lever 7 to pop out naturally and smoothly engage with the locking channel 3 simply by pressing the panel 4 during installation. This simple and direct operation improves installation efficiency. From the perspective of stability, the adaptation of the end of the locking lever 7 to the locking channel 3 ensures a tight fit and a stable connection, preventing the panel 4 from shaking or shifting due to external forces during use, ensuring that the panel 4 is securely installed within the mounting frame 1. Furthermore, this adaptation design can evenly distribute the external forces on the panel 4, avoiding excessive localized stress that could lead to damage, thereby extending the service life of the entire decorative frame structure.

[0050] Example 3:

[0051] This embodiment provides an interior decoration and renovation frame structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0052] The locking slot 2 is provided with multiple locking holes 11 for forming a multi-point locking with the locking lever 7.

[0053] The locking holes 11 and the locking levers 7 form a multi-point locking system, enhancing the stability and reliability of the connection between the panel 4 and the mounting frame 1. The locking holes 11 increase the number of contact points for locking, distributing the external force on the panel 4 and preventing excessive force at a single point from causing loosening or damage. The locking holes 11 are holes formed in the locking slots 2, typically circular or square, to accommodate the ends of locking levers 7 of different shapes. The locking holes 11 are evenly distributed within the locking channels 3 of the locking slots 2, corresponding to the locking levers 7, to achieve uniform multi-point locking.

[0054] Example 4:

[0055] This embodiment provides an interior decoration and renovation frame structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0056] The linkage mechanism 8 includes:

[0057] The return spring 80 is located inside the mounting base 6 and is connected to the bottom of the locking lever 7;

[0058] The drive rod 81 is connected to the bottom of the locking lever 7. The drive rod 81 is used to pull the locking lever 7 back by the return spring 80 to release the engagement with the locking channel 3.

[0059] The return spring 80 provides the reset force for the locking lever 7, enabling it to automatically pop out and engage with the locking channel 3 when the panel 4 is installed, and to retract against the spring force under the action of the drive rod 81 when the panel 4 is removed. The return spring 80 is installed inside the mounting base 6, with one end fixed to the mounting base 6 by welding, riveting, or a specific slot structure; the other end is connected to the bottom of the locking lever 7 by welding, riveting, or threading to ensure a firm connection and stable power transmission.

[0060] The drive rod 81 is used for manual control of the retraction of the locking lever 7, thereby releasing the panel 4 from the locking state of the mounting frame 1 and facilitating the removal of the panel 4. The drive rod 81 is a slender rod-shaped structure, with one end connected to the bottom of the locking lever 7 and the other end extending to the edge of the panel 4 or a position easily accessible to the operator. The end of the drive rod 81 connected to the bottom of the locking lever 7 can be fixed by welding or threaded connection.

[0061] This embodiment utilizes the elastic potential energy of the return spring 80 to automatically eject and lock the locking lever 7, and uses the pulling force of the drive rod 81 to overcome the elastic force of the return spring 80 to retract and unlock the locking lever 7. Based on the principle of elasticity, the return spring 80 stores energy when compressed and releases the energy to push the locking lever 7 when the external force is removed; the drive rod 81, based on the lever principle, allows the operator to apply a small pulling force, which is then transmitted to the locking lever 7 to achieve retraction of the locking lever 7.

[0062] Example 5:

[0063] This embodiment provides an interior decoration and renovation frame structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0064] The cross-section of the connector 9 is trapezoidal, and the insertion interface 10 is a corresponding trapezoidal groove, forming a seamless splicing surface after insertion.

[0065] In this embodiment, the connector 9 is designed with a trapezoidal cross-section, and the insertion interface 10 is designed with a corresponding trapezoidal groove. The main purpose is to achieve seamless splicing between the panels 4. The trapezoidal shape allows the connector 9 to be tightly inserted into the insertion interface 10. The two work together to effectively eliminate gaps at the splicing point, thereby improving the overall aesthetics of the interior decoration. At the same time, this design also improves installation accuracy, ensuring a tight and flat connection between adjacent panels 4, enhancing the stability and integrity of the structure, making the decorative effect more ideal, and also helping to improve the quality and durability of the entire frame structure.

[0066] Example 6:

[0067] This embodiment provides an interior decoration and renovation frame structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0068] The contact surface between the retaining plate 5 and the locking channel 3 is provided with an elastic buffer layer 12 to absorb the impact vibration during the installation of the panel 4.

[0069] The elastic buffer layer 12 is used to absorb the impact vibration generated during the installation of the panel 4, reducing damage to the panel 4 and the mounting frame 1. The elastic buffer layer 12 is a layer of elastic material that fits tightly against the contact surface between the retaining plate 5 and the locking channel 3. The elastic buffer layer 12 conforms to the shape of the contact surface between the retaining plate 5 and the locking channel 3, ensuring full-area cushioning. The elastic buffer layer 12 can be firmly adhered to the contact surface of the retaining plate 5 with adhesive.

[0070] Example 7:

[0071] This embodiment provides an interior decoration and renovation frame structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0072] The mounting chamber 102 is provided with mating structures 13 on the left and right sides, which correspond to the insertion interfaces 10 and insertion connectors 9 on the panel 4. The mating structures 13 are used to assist the panel 4 in lateral alignment.

[0073] The interlocking structure 13 is used to assist the panel 4 in achieving accurate alignment during horizontal splicing, reducing misalignment of the panel 4 caused by manual installation errors and improving structural stability. The interlocking structure 13 generally consists of protrusions and grooves, respectively located on the left and right sides of the mounting chamber 102, corresponding to the interlocking interfaces 10 and 9 on the panel 4. The interlocking structure 13 is located on the left and right edges of the mounting chamber 102, at the same height as the interlocking interfaces 10 and 9 on the panel 4. The interlocking structure 13 is integrally formed with the vertical bracket 101.

[0074] Example 8:

[0075] This embodiment provides an interior decoration and renovation frame structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0076] In this embodiment, a polytetrafluoroethylene (PTFE) self-lubricating coating is provided on the surface of the locking lever 7, and a nylon wear-resistant liner is embedded in the inner wall of the locking channel 3. The purpose of providing the PTFE self-lubricating coating on the surface of the locking lever 7 is to utilize the extremely low coefficient of friction of PTFE to reduce the frictional force of the locking lever 7 during operation, enabling smoother locking and unlocking actions, reducing wear, increasing service life, and making operation easier and more convenient. The nylon wear-resistant liner embedded in the inner wall of the locking channel 3 is because nylon has excellent wear resistance and self-lubricating properties, effectively protecting the inner wall of the locking channel 3, reducing frictional wear between it and the locking lever 7, preventing deformation or damage to the locking channel 3 due to long-term friction, thereby ensuring the reliability and stability of the locking mechanism and ensuring that the entire structure maintains good performance during long-term use.
