Description

Technical Field

[0001] This utility model relates to the field of interior decoration technology, and in particular to auxiliary devices for building interior decoration. Background Technology

[0002] In architectural interior decoration, suspended ceilings are a common decorative technique. A suspended ceiling refers to creating a decorative top structure with a specific shape and function by installing various materials on the existing ceiling.

[0003] Traditional ceiling installation first requires constructing a frame structure. Its basic structure mainly consists of metal rods connected by bolts and screws. During installation, workers need to cut the metal rods on-site according to the ceiling dimensions and design requirements, and then assemble the cut rods into a frame using welding. Afterward, the frame is fixed to the ceiling, and the ceiling panels are installed on top of the frame. This installation method has many drawbacks. On-site cutting and welding operations not only require specialized skills but are also cumbersome and time-consuming, significantly impacting construction efficiency.

[0004] Improvements have been made to existing technology, employing a hollow tube structure with supporting rods to construct the ceiling frame. During use, the size of the frame can be flexibly changed by adjusting the extension and retraction length of the supporting rods within the hollow tubes, improving installation convenience and frame size adaptability to some extent. However, in practical use, this structure requires bolts to fix the frame to the wall, which places extremely strict requirements on the flatness and hardness of the wall at the installation point. If the wall conditions do not meet the requirements, the firmness of the bolt fixation cannot be guaranteed. Furthermore, to ensure the frame's stability, multiple bolts often need to be tightened, making the operation still relatively cumbersome and increasing construction time and labor costs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an auxiliary device for building interior decoration, which aims to improve the problems of strict requirements for installation points and cumbersome operation in the existing frame installation method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary device for interior decoration of buildings, comprising two support rods, multiple square tubes, and multiple snap-on plates. An adjustment mechanism is provided on the outer wall of the two support rods, an extension assembly is provided between the multiple square tubes, and a quick-installation mechanism is provided between adjacent support rods. The adjustment mechanism includes multiple hollow sleeves, with one adjacent end of each hollow sleeve fixedly connected to the left and right sides of the outer wall of the two support rods. A threaded rod is slidably connected to the inner wall of each hollow sleeve. Limiting blocks are fixedly connected to the front and rear sides of the left end of the outer wall of each threaded rod. A limiting groove is formed on the front and rear sides of the left end of the inner wall of each hollow sleeve. The limiting blocks are slidably connected to the corresponding limiting grooves. A rotating sleeve is rotatably connected to the farthest end of each hollow sleeve. The rotating sleeves are threadedly connected to the corresponding threaded rods. A connecting assembly is provided at the farthest end of each threaded rod.

[0007] The above technical solution uses two support rods as basic support components. A hollow sleeve is fixed to the outer wall of the support rod, providing a sliding track for the threaded rod. When the rotating sleeve is rotated, because it is threadedly connected to the threaded rod, and the limiting block slides within the limiting groove to restrict the rotation of the threaded rod, the threaded rod can only move linearly within the hollow sleeve. This allows for adjustment of the extension length. The connecting component at the end of the threaded rod away from the support rod is used to connect subsequent components, such as connecting to a square tube, thereby enabling adjustment of the distance between the entire device and the wall, meeting the needs of different interior decoration scenarios.

[0008] As a further description of the above technical solution:

[0009] The quick-installation mechanism includes multiple mounting rods, the front and rear ends of which are fixedly connected to the adjacent sides of two support rods. Multiple reserved slots are provided on the left and right sides of the outer walls of the multiple mounting rods and on the adjacent sides of the multiple square tubes. Springs are fixedly connected to the inner walls of the multiple reserved slots. Locking blocks are fixedly connected to the outer walls of the multiple springs. Multiple locking slots are provided on the left and right sides of the outer walls of the multiple buckles. The locking blocks engage with the corresponding locking slots.

[0010] Through the above technical solution: when the quick-installation mechanism is working, the installation rod is first fixed on the adjacent sides of the two support rods to provide support for the installation of the buckle panel. When the buckle panel approaches the installation rod, the slot on its outer wall contacts the locking block. As the buckle panel moves further, the locking block is squeezed and slides into the reserved slot, compressing the spring. When the slot aligns with the reserved slot, the spring releases its elastic potential energy, pushing the locking block into the slot, completing the quick installation of the buckle panel. No complicated tools or operations are required, which improves the efficiency of interior decoration buckle panel installation.

[0011] As a further description of the above technical solution:

[0012] The connecting assembly includes multiple connecting seats. The outer walls of the multiple connecting seats are respectively fixedly connected to the opposite ends of the multiple connecting assemblies. Each opposite end of the multiple square tubes is fixedly connected with a locking block. Each locking block engages with a corresponding connecting seat. The inner walls of the multiple locking blocks are threaded with bolts. The bottom ends of the multiple bolts are threadedly connected to the corresponding connecting seats.

[0013] The above technical solution involves first fixing the connecting seat to the end of the threaded rod. When installing the square tube, the locking block at the end of the square tube is engaged with the connecting seat to initially position the square tube. Then, bolts are screwed into the inner wall of the locking block to make the bottom end of the bolts threadedly connected to the connecting seat. As the bolts are tightened, the connection between the locking block and the connecting seat becomes increasingly secure, thereby firmly connecting the square tube to the threaded rod and completing the structural construction.

[0014] As a further description of the above technical solution:

[0015] The extension assembly includes two extension rods. The front ends of the two extension rods are respectively fixedly connected to the rear side of the outer wall of the two front square tubes. The front side of the inner wall of the two rear square tubes is provided with a sliding groove. The two extension rods are slidably connected to the corresponding sliding grooves. Two limiting strips are fixedly connected to the outer wall of the two extension rods on the side away from each other. Two limiting grooves are provided on the inner wall of the two sliding grooves on the side away from each other. The multiple limiting strips are slidably connected to the corresponding limiting grooves.

[0016] Through the above technical solution: the extension rod on the front square tube and the sliding groove of the rear square tube form a sliding pair. When it is necessary to adjust the spacing between the square tubes, the extension rod slides in the sliding groove. At the same time, the limiting strip on the extension rod slides in conjunction with the limiting groove on the inner wall of the sliding groove to prevent the extension rod from deviating or coming off during the sliding process, ensuring the stability and accuracy of the distance adjustment between the square tubes and meeting the needs of different interior decoration space sizes.

[0017] As a further description of the above technical solution:

[0018] Both the left and right buckle plates are fixedly connected to rubber strips on opposite sides, and each rubber strip has two reinforcing ribs inside.

[0019] The above technical solution involves rubber strips on the left and right sides of the snap-on panels that are furthest apart, used to fill the gaps between the snap-on panels and the wall. Internal reinforcing ribs enhance the strength of the rubber strips, enabling them to better perform their sealing and stabilizing functions.

[0020] As a further description of the above technical solution:

[0021] Each of the multiple locking blocks has a circular pre-drilled hole at its top, and the inner wall of each of the multiple circular pre-drilled holes is larger than the outer diameter of the corresponding bolt.

[0022] The above technical solution involves creating a circular pre-drilled hole at the top of the locking block. The inner diameter of the hole is larger than the outer diameter of the bolt, allowing the installer to insert a tool and tighten the bolt to secure the component.

[0023] As a further description of the above technical solution:

[0024] Multiple pressure plates are fixedly connected to the top of each of the mounting rods, and the same fireproof board is fixedly connected to the top of each of the multiple pressure plates. A waterproof cloth is fixedly connected to the top of the fireproof board.

[0025] The above technical solution involves a pressure plate at the top of the mounting rod applying downward pressure to the buckle plate to prevent it from tilting up. The pressure plate supports the fireproof board, which enhances the overall fire resistance. The waterproof cloth on the fireproof board blocks moisture, preventing the device from getting damp and damaged, and extending its service life.

[0026] As a further description of the above technical solution:

[0027] Multiple anti-slip strips are fixedly connected to the outer walls of the multiple rotating sleeves, and the multiple anti-slip strips are arranged in a ring with the center of the corresponding rotating sleeve as the center.

[0028] The above technical solution involves annular anti-slip strips on the outer wall of the rotating sleeve, which increase the friction between the hand and the rotating sleeve, making it easier and more stable for the person to rotate the rotating sleeve.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the threaded rod and hollow sleeve, the limiting block and limiting groove, and the rotating sleeve and threaded rod are coordinated. Rotating the rotating sleeve can adjust the extension length of the threaded rod and make it fit against the wall. The support rod is fixed by the friction between the connecting seat and the wall, eliminating the need to drill holes in the wall and reducing the requirements for wall installation points. The square tube is engaged with the connecting seat by the locking block and then tightened with bolts, realizing the rapid construction of the frame. These structural combinations improve the problem of strict installation point requirements and cumbersome operation in the existing technology for installing frames, effectively improving construction efficiency.

[0031] 2. In this utility model, the fixed connection between the mounting rod and the support rod lays the foundation for the installation of the buckle plate. The cooperation of the pre-reserved groove on the mounting rod and the spring and the locking block, when the buckle plate approaches the mounting rod, the buckle plate squeezes the locking block to compress the spring. When the locking groove is aligned with the pre-reserved groove, the spring releases its elastic potential energy to push the locking block into the locking groove, restricting the horizontal movement of the buckle plate, realizing rapid installation, greatly improving the installation efficiency of the buckle plate, and solving the problem of low efficiency in traditional installation methods.

[0042] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Reference Figure 3 , Figure 4 and Figure 7 This utility model provides an embodiment of an auxiliary device for building interior decoration, comprising two support rods 1, multiple square tubes 4, and multiple snap-on plates 6. The support rods 1 serve as the main support components of the entire device, providing a support foundation for the subsequent structure. The square tubes 4 are used to construct the main body of the ceiling frame, forming a frame structure. The snap-on plates 6 are used to cover the surface of the frame, serving a decorative and protective function. The outer walls of the two support rods 1 are provided with adjustment mechanisms 2, which are used to flexibly adjust the connection position between the device and the wall according to the actual wall distance. Extension components 5 are provided between the multiple square tubes 4, which can adjust the distance between the square tubes 4 to adapt to different space size requirements. Quick-installation mechanisms 3 are provided between the adjacent two support rods 1 to achieve rapid installation of the snap-on plates 6 and improve construction efficiency.

[0044] The adjustment mechanism 2 includes multiple hollow sleeves 201. One adjacent end of each hollow sleeve 201 is fixedly connected to the left and right sides of the outer wall of two support rods 1. Each hollow sleeve 201 has a threaded rod 202 slidably connected to its inner wall. The threaded rod 202 slides within the hollow sleeve 201 to adjust the distance between the device and the wall. Limiting blocks 203 are fixedly connected to the front and rear sides of the left end of the outer wall of each threaded rod 202. Limiting grooves 204 are formed on the front and rear sides of the left end of the inner wall of each hollow sleeve 201. The limiting blocks 203 slidably connect with their corresponding limiting grooves 204. Next, the limiting groove 204 provides sliding space for the limiting block 203 to ensure the normal operation of the limiting block 203. The opposite ends of the multiple hollow sleeves 201 are rotatably connected to the rotating sleeves 205. The rotation drives the threaded rod 202 to move inside the hollow sleeve 201, thereby adjusting the extension length of the threaded rod 202. The multiple rotating sleeves 205 are respectively threadedly connected to the corresponding threaded rods 202. Using the thread transmission principle, the rotation of the rotating sleeves 205 is converted into the linear movement of the threaded rods 202. The opposite ends of the multiple threaded rods 202 are provided with connecting components 206.

[0045] The connecting component 206 includes multiple connecting seats 2061, which serve as intermediate components connecting the threaded rod 202 and the square tube 4, providing a connection basis for the two. The outer walls of the multiple connecting seats 2061 are respectively fixedly connected to the opposite ends of the multiple connecting components 206, fixing the connecting seats 2061 to the end of the threaded rod 202 to ensure connection stability. Each opposite end of the multiple square tubes 4 is fixedly connected with a locking block 2062, which engages with the corresponding connecting seat 2061 to achieve the initial connection between the square tube 4 and the connecting seat 2061. The inner walls of the multiple locking blocks 2062 are threaded with bolts 2063 to further tighten the connection between the square tube 4 and the connecting seat 2061, ensuring the stability of the frame structure. The bottom ends of the multiple bolts 2063 are threadedly connected to the corresponding connecting seat 2061.

[0046] Specifically, the two support rods 1 provide a supporting foundation for the overall structure. The hollow sleeve 201 in the adjusting mechanism 2 is fixed to the outer wall of the support rod 1, and its inner wall is slidably connected to the threaded rod 202, enabling the extension and retraction of the threaded rod 202. The limiting block 203 slides into the limiting groove 204 on the inner wall of the hollow sleeve 201 to prevent the threaded rod 202 from rotating, ensuring that it can only move axially. The rotating sleeve 205 is rotatably connected to the hollow sleeve 201 and threadedly connected to the threaded rod 202. Rotating the rotating sleeve 205 drives the threaded rod 202 to move within the hollow sleeve 201, adjusting the extension length. The connecting seat 2061 of the connecting assembly 206 is fixed to the end of the threaded rod 202 for connecting the square tube 4. The engaging block 2062 at the end of the square tube 4 engages with the connecting seat 2061, initially positioning the square tube 4. Then, the engaging block 2062 is threadedly connected to the connecting seat 2061 using bolts 2063, firmly fixing the square tube 4 and thus constructing the frame structure. The entire adjustment mechanism 2 and the connecting component 206 work together to enable the device to flexibly adjust the frame position and build it stably according to the distance from the wall, which solves the problems of strict requirements for installation points and complicated operation of the installation frame, and meets the actual needs of interior decoration.

[0047] Reference Figure 3 and Figure 6 The quick-installation mechanism 3 includes multiple mounting rods 301, which serve as the basic support components of the quick-installation mechanism 3, providing a carrier for subsequent connection and installation. The front and rear ends of the multiple mounting rods 301 are respectively fixedly connected to the adjacent sides of two support rods 1. Multiple reserved slots 302 are opened on the left and right sides of the outer walls of the multiple mounting rods 301 and the adjacent sides of the multiple square tubes 4. The reserved slots 302 are used to accommodate springs 303 and locking blocks 304, providing them with installation space. Springs 303 are fixedly connected to the inner walls of the multiple reserved slots 302. 03. Utilizing its own elastic potential energy, the spring 303 provides extension and retraction power for the locking block 304. The outer walls of multiple springs 303 are fixedly connected with locking blocks 304. Under the action of the springs 303, they cooperate with the locking slots 305 on the buckle plate 6 to realize the quick installation and fixation of the buckle plate 6. Multiple locking slots 305 are opened on the left and right sides of the outer walls of multiple buckle plates 6. Multiple locking blocks 304 are respectively engaged with the corresponding locking slots 305. The locking slots 305 and locking blocks 304 cooperate with each other to fix the position of the buckle plate 6 and prevent it from moving at will.

[0048] Specifically, multiple mounting rods 301 are fixed to the adjacent sides of two support rods 1 via their front and rear ends, providing support for the installation of the buckle plate 6. Pre-drilled slots 302 on the left and right sides of the outer wall of the mounting rods 301, adjacent to the square tube 4, are used to accommodate springs 303 and locking blocks 304. One end of the spring 303 is fixed to the inner wall of the pre-drilled slot 302, and the other end is connected to the locking block 304, using its own elasticity to provide extension and retraction power for the locking block 304. The locking grooves 305 on the left and right sides of the outer wall of the buckle plate 6 correspond to and cooperate with the locking blocks 304. When installing the buckle plate 6, the buckle plate 6 approaches the mounting rods 301, pressing the locking blocks 304 to slide into the pre-drilled slots 302 and compressing the springs 303. When the buckle plate 6 moves until the locking grooves 305 align with the pre-drilled slots 302, the spring 303 releases its elastic potential energy, pushing the locking blocks 304 into the locking grooves 305, restricting the movement of the buckle plate 6, completing the rapid installation and improving construction efficiency.

[0049] Reference Figure 1 , Figure 2 and Figure 8 The extension assembly 5 includes two extension rods 501. The front ends of the two extension rods 501 are respectively fixedly connected to the rear side of the outer wall of the two front square tubes 4 to increase the adjustable length between the square tubes 4 to adapt to different sizes of installation space. The front side of the inner wall of the two rear square tubes 4 is provided with a sliding groove 502. The sliding groove 502 provides a sliding track for the extension rods 501, so that the extension rods 501 can slide smoothly in the square tubes 4. The two extension rods 501 are slidably connected to the corresponding sliding grooves 502.

[0050] Two limiting strips 503 are fixedly connected to the outer walls of the two extension rods 501 on the side away from each other. Two limiting grooves 504 are opened on the inner walls of the two slides 502 on the side away from each other. The multiple limiting strips 503 are slidably connected to the corresponding limiting grooves 504. The limiting grooves 504 provide sliding space for the limiting strips 503, ensuring that the limiting strips 503 can properly play the role of limiting the offset of the extension rods 501.

[0051] Rubber strips 7 are fixedly connected to the opposite sides of the left and right snap-on panels 6 to fill the gaps between the snap-on panels 6 and the wall, playing a role in sealing, shock absorption and buffering, and enhancing the stability of the installation structure. Two reinforcing ribs 8 are provided inside the two rubber strips 7 to prevent the rubber strips 7 from deforming or being damaged by external forces, ensuring that they can effectively fill gaps and stabilize the structure for a long time.

[0052] Specifically, when the extension component 5 is in operation, the distance between the square tubes 4 is adjusted by sliding the extension rod 501 within the slide groove 502. The limiting strip 503 cooperates with the limiting groove 504 to prevent the extension rod 501 from shifting during sliding, ensuring stable adjustment. After the buckle plate 6 is installed, the rubber strips 7 on both sides of the buckle plate 6 fill the gaps between it and the wall to prevent loosening. The reinforcing ribs 8 inside the rubber strips 7 enhance the strength of the rubber strips 7, ensuring the reliability of its anti-loosening and gap-filling functions.

[0053] Reference Figure 1 , Figure 5 and Figure 7 The top of each of the multiple locking blocks 2062 is provided with a circular pre-drilled hole 9 to provide space for the operating tool to apply force. The inner wall of each of the multiple circular pre-drilled holes 9 is larger than the outer diameter of the corresponding bolt 2063, so that the tool can be smoothly inserted into the circular pre-drilled hole 9 to tighten the bolt 2063.

[0054] Multiple mounting rods 301 are fixedly connected to the top of multiple pressure plates 10, which apply downward pressure to the buckle plate 6 to prevent the buckle plate 6 from tilting upward after installation, ensuring the flatness and stability of the buckle plate 6 installation. The top of the multiple pressure plates 10 is fixedly connected to the same fireproof plate 11, which can improve the fire resistance of the entire device, reduce the safety risk in the event of a fire, and protect the indoor environment and personnel safety. The top of the fireproof plate 11 is fixedly connected to a waterproof cloth 12, which plays a role in waterproofing and moisture-proofing, preventing moisture from penetrating into the device, extending the service life of the device, and preventing damage or deformation of components due to moisture. Multiple anti-slip strips 13 are fixedly connected to the outer walls of multiple rotating sleeves 205, which increases the friction between the rotating sleeve 205 and the operator's hand. The multiple anti-slip strips 13 are arranged in a ring with the center of the corresponding rotating sleeve 205 as the center, ensuring that the friction can be effectively increased in all directions, making it easier and more stable for the operator to rotate the rotating sleeve 205.

[0055] Specifically, the circular pre-drilled hole 9 at the top of the locking block 2062, with its inner wall larger than the outer diameter of the bolt 2063, facilitates the use of tools to tighten the bolt 2063, making it easy to fasten the square tube 4 and the connecting seat 2061. The pressure plate 10 at the top of the mounting rod 301 prevents the buckle plate 6 from tilting upwards. Multiple pressure plates 10 together support the fireproof plate 11 at the top, which is then connected to the waterproof cloth 12, providing both fireproofing and waterproofing. The anti-slip strips 13 arranged in a ring around the outer wall of the rotating sleeve 205 increase friction, making it easy for construction personnel to rotate the rotating sleeve 205 and adjust the extension length of the threaded rod 202.

[0056] Working Principle: In use, firstly, based on the distance between the two walls, adjust the approximate extension length of the two threaded rods 202 to prepare for subsequent installation. Then, place the two support rods 1 in suitable positions. Next, rotate multiple rotating sleeves 205. Because the limiting block 203 and the limiting groove 204 on the inner wall of the hollow sleeve 201 are in sliding fit, the threaded rods 202 can only move left and right within the hollow sleeve 201 when rotating the rotating sleeves 205, based on the threaded transmission principle. Therefore, rotating the rotating sleeves 205 drives the threaded rods 202 to move and conform to the wall. After the threaded rods 202 contact the wall, continue to rotate the rotating sleeves 205. At this time, multiple connecting seats 2061 will tightly press against the wall. Using this friction, the position of the two support rods 1 can be fixed, preventing them from moving arbitrarily. This step significantly reduces the requirements for the wall mounting point compared to the traditional method of using bolts 2063 for fixing, and the operation is much simpler. Afterwards, begin assembling the frame. The locking blocks 2062 at both ends of the square tube 4 are engaged with the connecting seats 2061 to lock onto the corresponding connecting seats 2061. After engagement, the bolts 2063 are tightened to securely fix the multiple square tubes 4, completing the installation of the main frame. This achieves rapid, drill-free installation of the frame, solving the problems of strict requirements for wall mounting points and cumbersome operations in existing technologies, and improving construction efficiency.

[0057] Furthermore, when installing the buckle plate 6, the mounting rod 301 is first fixed to the adjacent side of the two support rods 1, providing basic support for the installation of the buckle plate 6. At this time, springs 303 have been pre-fixed in the reserved grooves 302 on the left and right sides of the outer walls of multiple mounting rods 301 and on the adjacent side of multiple square tubes 4, and the other end of the springs 303 is connected to the locking blocks 304. Subsequently, the construction personnel hold the buckle plate 6 and gradually approach the mounting rods 301. During the movement of the buckle plate 6, the left and right sides of the buckle plate 6 will contact the corresponding locking blocks 304 respectively. As the buckle plate 6 moves upward, the buckle plate 6 will squeeze the corresponding locking blocks 304, causing the locking blocks 304 to slide into their corresponding reserved grooves 302. During this process, the springs 303 are compressed. When the snap-on plate 6 moves to a specific position, i.e., when the slot 305 aligns with the pre-drilled slot 302, the clamping block 304 is no longer restricted by the snap-on plate 6. The compressed spring 303 releases its elastic potential energy, pushing the clamping block 304 outwards, allowing it to precisely engage with the corresponding slot 305. At this point, the horizontal movement of the snap-on plate 6 is restricted, thus completing the rapid installation of the snap-on plate 6. This design, utilizing the cooperation of the spring 303 and the clamping block 304, eliminates the need for additional tools or complex operations, greatly improving the installation efficiency of the snap-on plate 6 and achieving a fast and convenient installation process.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
