Description

Technical Field

[0001] This utility model relates to the field of ceiling installation technology, and in particular to a bottom connecting rod applied to a hyperboloid ceiling installation structure. Background Technology

[0002] In the field of architectural interior decoration, hyperboloid ceilings are favored for their beautiful streamlined shape, but their complex curved structure also places higher demands on the installation components. Currently, such ceilings generally adopt the installation method of keel combined with suspension system.

[0003] However, existing ceiling systems have significant shortcomings in terms of adjustability and ease of disassembly. In actual installation and subsequent maintenance, it is often necessary to fine-tune the installation angle or position of the ceiling panels to ensure a smooth transition of the hyperboloid shape. However, traditional hanging components mostly use bolt fastening or snap-locking structures, which require special tools to repeatedly tighten and loosen during adjustment, making the operation cumbersome and inefficient. In addition, when disassembling individual panels for maintenance, this rigid connection method is prone to collisions between adjacent panels or human-caused damage to the panels to be disassembled due to limited operating space. Especially for the weak edges of hyperboloid panels, improper prying often causes irreversible damage, seriously affecting the effectiveness of secondary installation.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide a bottom connecting rod for a hyperboloid ceiling installation structure. The device has an assembly head at the bottom of the bottom connecting rod, and the assembly head adopts a 1 / 4 spherical structure. An installation plate is set at the top center of the ceiling panel, and an assembly hole is opened at the top center of the installation plate. The assembly hole adopts a groove structure that matches the assembly head, so that the assembly head can be rotated and adjusted after being fitted into the assembly hole, thereby making it more convenient to adjust the angle of the ceiling panel.

[0006] To achieve the above objectives, this utility model provides a bottom connecting rod for a hyperboloid ceiling installation structure, which is set between the keel frame and the ceiling panel. As the main component for suspending and connecting the keel frame and the ceiling panel, it includes a bottom connecting rod. The bottom of the bottom connecting rod is provided with an assembly head, which adopts a 1 / 4 spherical structure. The ceiling panel is provided with a mounting plate at the top center position. The mounting plate has an assembly hole at the top center position. The assembly hole adopts a groove structure adapted to the assembly head, so that the assembly head can be rotated and adjusted after being fitted into the assembly hole.

[0007] In one embodiment of this utility model, an upper tube body is further included for use with a bottom connecting rod. The top of the upper tube body is fixed below the keel structure. The bottom connecting rod is movably inserted into the upper tube body. The bottom of the bottom connecting rod extends from the bottom of the upper tube body. The bottom connecting rod can be positioned in a first position and a second position under external constraints. When the bottom connecting rod is in the first position, it is a fixed position where the current ceiling panel is flush with the already installed ceiling panel. When the bottom connecting rod is in the second position, it is an adjustable position where the current ceiling panel is misaligned with the already installed ceiling panel.

[0008] In one embodiment of this utility model, a positioning mechanism is installed on the upper sides of the upper tube body. The positioning mechanism can position the bottom connecting rod in a first position and a second position when the bottom connecting rod moves. A positioning and cooperating mechanism is provided above the bottom connecting rod, which can cooperate with the positioning mechanism to position the bottom connecting rod in the first position and the second position when the bottom connecting rod moves up and down.

[0009] In one embodiment of this utility model, the positioning mechanism includes two limiters, which are installed symmetrically above the outer side of the upper tube body. A limiting element is slidably installed inside the limiter, and a spring is provided between the limiting element and the inner wall of the limiter. The spring enables the limiting element to move radially toward the center of the upper tube body.

[0010] In one embodiment of this utility model, the positioning and mating mechanism includes a clip that is slidably sleeved on the bottom connecting rod. The top of the clip has a frustum-shaped structure, and a cavity is provided above the clip. A protrusion that limits the positioning of the clip is also provided above the outer wall of the bottom connecting rod. An installation groove is provided inside the bottom connecting rod along the length direction, and a positioning member is installed inside the installation groove. The top of the positioning member is bent outward.

[0011] In one embodiment of this utility model, a first magnet is provided at the bottom of the positioning member, and a second magnet is installed on the inner side of the clip along the radial direction of the mounting groove. The magnetic poles of the second magnet and the first magnet are in the same direction. When the positioning member gradually approaches the cavity, a repulsive force is gradually generated between the second magnet and the first magnet. This repulsive force can push the clip downward during the process of the secondary control bottom connecting rod moving to the first position, so that it can separate from the positioning member.

[0012] In one embodiment of this utility model, the top of the bottom connecting rod adopts a conical structure, and the bottom of the limiting member adopts a wedge-shaped structure.

[0013] Compared with the prior art, the bottom connecting rod of this utility model, applied to the installation structure of a hyperboloid ceiling, features an assembly head at the bottom of the bottom connecting rod. The assembly head has a 1 / 4 spherical structure, and an installation plate is located at the top center of the ceiling panel. An assembly hole is formed at the top center of the installation plate, and the assembly hole has a groove structure that fits the assembly head. This allows the assembly head to be rotated and adjusted after being fitted into the assembly hole, making it more convenient to adjust the angle of the ceiling panel, especially for installation on curved ceilings. Furthermore, this device, through its bottom connecting rod... The connecting rod and its matching upper tube are structurally designed to form a convenient misalignment adjustment component. This makes it easy to operate the ceiling panel during installation and disassembly, as well as when adjusting the angle after installation. Simply push the ceiling panel upward to misalign it with the surrounding ceiling panels, then tilt it using its own weight, and then pull it downward. Once the ceiling panel is misaligned below the surrounding ceiling panels, adjust it again. The entire process is designed to minimize damage to the ceiling panel and ensure its reusability.

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 10 The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0026] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0027] like Figure 1 - Figure 10 As shown, a bottom connecting rod for a hyperboloid ceiling installation structure according to a preferred embodiment of the present invention includes a keel frame 1, a ceiling panel 11, a misalignment adjustment component, and a secondary protection component. The keel frame 1 is fixed to the roof. The ceiling panel 11 has a curved structure. An installation plate 22 is provided at the upper center of the ceiling panel 11. The misalignment adjustment component is provided between the ceiling panel 11 and the keel frame 1 to suspend the ceiling panel 11 below the keel frame 1. The secondary protection component is provided above the ceiling panel 11 to protect the ceiling panel 11 in case of abnormal fall. The secondary protection component includes an elastic protective sheet 5 and a main pipe 41. One end of the elastic protective sheet 5 is fixed to the edge of the installation plate 22, and the other end of the elastic protective sheet 5 extends beyond the edge of the ceiling panel 11. The main pipe 41 is provided above the elastic protective sheet 5. A protective rod 43 is movably installed at one end of the main pipe 41. The protective rod 43 can slide in the main pipe 41 so that one end of it extends beyond the edge of the ceiling panel 11.

[0028] Working Principle: This device is used for the installation of hyperboloid ceilings. In use, the keel frame 1 is first fixed to the roof, serving as the support for the ceiling panels 11. Then, the ceiling panels 11 are suspended below the keel frame 1 using the offset adjustment component. During suspension, the guard rod 43 is first retracted until its front end is within the coverage area of ​​the current ceiling panel 11. Then, the ceiling panel 11 is pushed upwards. After the guard rod 43 passes the position of the surrounding ceiling panels 11, there is an offset gap between the current ceiling panel 11 and the surrounding ceiling panels 11. This gap is used to control the guard rod 43 to extend outwards until its front end exceeds the edge of the current ceiling panel 11. The device is then pushed upwards again. During the installation of the ceiling panel 11, one end of the elastic protective plate 5 is lifted upwards so that its front end is within the coverage area of ​​the current ceiling panel 11, and the ceiling panel 11 is continuously pushed upwards until it is flush with the surrounding ceiling panels 11. After installation, since the front end of the protective rod 43 and the front end of the elastic protective plate 5 are both within the coverage area of ​​the adjacent ceiling panel 11, when the ceiling panel 11 falls accidentally, the elastic protective plate 5 on the ceiling panel 11 first gets stuck on the top surface of the surrounding ceiling panels 11, achieving a primary fall prevention effect. When the ceiling panel 11 squeezes the elastic protective plate 5, causing it to fall over the surrounding ceiling panels 11, the protective rod 43 can get stuck on the top surface of the surrounding ceiling panels 11, achieving a secondary fall prevention effect.

[0029] In summary, this device, by installing a secondary protective component above the ceiling panel 11—namely, a primary protective structure composed of elastic protective sheets 5 and a secondary protective structure composed of protective rods 43 and main pipes 41—ensures that when the ceiling panel 11 falls abnormally, it can protect the ceiling panel 11 by cooperating with surrounding ceiling panels 11. This prevents the ceiling panel 11 from falling completely and causing injury, as well as from falling from a high height and deforming upon impact, making it difficult to reinstall and use.

[0030] Specifically, such as Figure 1 - Figure 4 As shown, in order to improve the protection effect by creating a height difference between the two secondary protection components during protection, the main pipe 41 adopts an inverted L-shaped structure in this embodiment. The protective rod 43 is movably inserted into the horizontal end of the main pipe 41. A bracket 44 is installed above the mounting plate 22 corresponding to the position of the main pipe 41, and the vertical end of the main pipe 41 is fixedly installed on the bracket 44.

[0031] Specifically, such as Figure 4 and Figure 5As shown, in order to improve the support stability of the main pipe 41, in this embodiment, a diagonal brace 42 is also installed on the main pipe 41. One end of the diagonal brace 42 is fixed to the vertical end of the main pipe 41, and the other end is fixed to the horizontal end of the main pipe 41, so that the diagonal brace 42 and the main pipe 41 form a triangular structure, thereby improving the support stability of the main pipe 41.

[0032] Specifically, such as Figure 4 and Figure 5 As shown, to facilitate control of the protective rod 43, in this embodiment, a first piston 46 is installed at one end of the protective rod 43 inserted into the main pipe 41. A control rod 45 is movably inserted below the vertical end of the main pipe 41. A second piston 47 is provided at one end of the control rod 45 inserted into the main pipe 41. A stop block 49 is installed at the bottom of the vertical end of the main pipe 41. A spring 48 is provided between the second piston 47 and the stop block 49. The spring 48 is sleeved on the control rod 45. Based on this, when the control rod 45 moves, the protective rod 43 moves synchronously under the action of air pressure inside the main pipe 41. When the spring 48 moves... In its natural state, the protective rod 43 extends beyond the edge of the current ceiling panel 11. When the control rod 45 is pulled down, compressing the spring 48, the protective rod 43 moves synchronously towards one end of the main pipe 41, gradually retracting its front end to within the edge of the current ceiling panel 11. At this time, the ceiling panel 11 can be assembled. After assembly, the control rod 45 is released, and under the elastic force of the spring 48, the control rod 45 moves upward, causing the front end of the protective rod 43 to extend beyond the edge of the current ceiling panel 11, thus achieving protection. This structure, which controls the protective rod 43 from below, makes operation more convenient.

[0033] Specifically, such as Figure 1 - Figure 5 As shown, to enhance the protective effect, in this embodiment, four sets of elastic protective plates 5 and main pipes 41 are provided. The four sets of elastic protective plates 5 and main pipes 41 are arrayed above the ceiling panel 11, and the four sets of elastic protective plates 5 and main pipes 41 are installed in a staggered manner. Based on this, the four sets of elastic protective plates 5 and main pipes 41 can provide protection from four directions simultaneously, resulting in higher safety. In addition, it should be noted that in order to facilitate the simultaneous control of the control rods 45 on the four sets of main pipes 41 to move downwards, so that the four sets of protective rods 43 can retract synchronously for easy installation, the four sets of main pipes 41 are connected by a connecting rod (not shown in the figure). Furthermore, in order to make the downward stroke of the control rod 45 greater than the retraction stroke of the protective rod 43, the control rod 45 can be pulled shorter when the protective rod 43 is retracted. The inner diameter of the vertical end of the main pipe 41 is greater than the inner diameter of the horizontal end of the main pipe 41. Therefore, the moving stroke of the control rod 45 is less than the moving stroke of the protective rod 43, thus facilitating the control of the protective rod 43.

[0034] Specifically, such as Figure 1 - Figure 3 and Figure 6 - Figure 10 As shown, in order to achieve the suspended installation of the ceiling panel 11, in this embodiment, the bottom of the keel frame 1 is bolted or welded to the center position of the ceiling panel 11. The bottom of the connector 2 is provided with a threaded hole 21. The misalignment adjustment component includes a controllable lifting rod, which consists of an upper tube 3 and a bottom connecting rod 35 that is movably inserted into the upper tube 3. The center position of the mounting plate 22 is provided with an assembly hole 23. The bottom of the bottom connecting rod 35 extends from the bottom of the upper tube 3 and is inserted into the assembly hole 23. The top of the upper tube 3 is screwed into the threaded hole 21. The bottom connecting rod 35 in the controllable lifting rod can be positioned in a first position and a second position under external constraints, wherein the bottom connecting rod 35 is in the first position. When the ceiling panel 11 is in its fixed position, flush with the already installed ceiling panel 11, and the bottom connecting rod 35 is in its second position, the ceiling panel 11 is adjusted to be misaligned with the already installed ceiling panel 11. Based on this, when the bottom connecting rod 35 is in the second position, the angle of the ceiling panel 11 can be adjusted. After adjustment, by pushing the ceiling panel 11 upward, the bottom connecting rod 35 can be moved upward until it reaches the first position, at which point the assembly is complete. The operation is convenient. In addition, if the angle of a ceiling panel 11 is not aligned after assembly, the ceiling panel 11 can be pushed upward again to move the bottom connecting rod 35 above the ceiling panel 11 to the second position, and the above adjustment operation can be repeated.

[0035] Specifically, such as Figure 1 - Figure 3 and Figure 6 - Figure 10 As shown, in order to achieve controllable length control of the lifting rod, that is, to control the bottom connecting rod 35 to be positioned in the first position and the second position, in this embodiment, the upper sides of the upper tube body 3 have positioning mechanisms. The positioning mechanisms can position the bottom connecting rod 35 in the first position and the second position when the bottom connecting rod 35 moves. A positioning and cooperating mechanism is provided above the bottom connecting rod 35, which can cooperate with the positioning mechanism to position the bottom connecting rod 35 in the first position and the second position when the bottom connecting rod 35 moves up and down.

[0036] Specifically, such as Figure 1 - Figure 3 and Figure 6 - Figure 10 As shown, in order to position the bottom connecting rod 35, in this embodiment, the positioning mechanism includes two limiters 31. The two limiters 31 are installed symmetrically above the outer side of the upper tube 3. A limiter 32 is slidably installed inside the limiter 31. A spring is provided between the limiter 32 and the inner wall of the limiter 31. The spring enables the limiter 32 to have a tendency to move radially upward toward the center of the tube 3.

[0037] Specifically, such as Figure 1 - Figure 3 and Figure 6 - Figure 10 As shown, for positioning the bottom connecting rod 35, in this embodiment, the positioning and mating mechanism includes a locking member 34 that is slidably sleeved on the bottom connecting rod 35. The top of the locking member 34 adopts a frustum-shaped structure, and a cavity 38 is opened above the locking member 34. A protrusion 350 for limiting the locking member 34 is also provided on the upper part of the outer wall of the bottom connecting rod 35. An installation groove 36 is opened inside the bottom connecting rod 35 along the length direction. A positioning member 37 is installed inside the installation groove 36. The top of the positioning member 37 is bent outward. Based on this, when the bottom connecting rod 35 is in the initial position, the positioning member 37 and the locking member 34 are both located below the limiting member 32. When the bottom connecting rod 35 moves upward, the bent structure above the positioning member 37 first contacts the limiting member 32. Since the top of the positioning member 37 adopts a wedge-shaped structure, the positioning member 37 can gradually squeeze the limiting member 32, causing it to move into the limiting device 31 until the positioning member 37 passes the limiting member 32, releasing the bottom connecting rod 35. 7. The bottom connecting rod 35 is positioned in the first position, and the bottom connecting rod 35 is positioned above the limiting member 32. When it is necessary to control the bottom connecting rod 35 to be positioned in the second position, push the ceiling panel 11 upward to make the bottom connecting rod 35 continue to move upward until the edge of the clamping member 34 is clamped between the two limiting members 32. At this time, the clamping member 34 is clamped and fixed. Then pull the bottom connecting rod 35 downward. At this time, the clamping member 34 is fixed, and the bottom connecting rod 35 and the positioning member 37 move downward. When the positioning member 37 moves to the top, the bottom connecting rod 35 is positioned in the second position. As the cavity 38 continues to move downward, the entire bottom connecting rod 35, including the positioning piece 37 and the locking piece 34, passes over the limiting piece 32, and the bottom connecting rod 35 is positioned in the second position. In summary, during the entire operation, it is only necessary to lift the ceiling panel 11 upward to move the ceiling panel 11 upward a certain distance. After the ceiling panel 11 separates from the surrounding ceiling panels 11, the ceiling panel 11 is then pulled down to move the ceiling panel 11 downward and offset it from the other ceiling panels 11, thereby achieving disassembly and adjustment. The operation is convenient and quick.

[0038] Specifically, such as Figure 1 - Figure 3 and Figure 6 - Figure 10As shown, in order to enable secondary control of the bottom connecting rod 35 to move to the first position for the installation of the ceiling panel 11, in this embodiment, a first magnet 370 is provided at the bottom of the positioning member 37, and a second magnet 33 is installed radially along the mounting groove 36 on the inner side of the clamping member 34. The magnetic poles of the second magnet 33 and the first magnet 370 are in the same direction. Based on this, when the positioning member 37 gradually approaches the cavity 38, a repulsive force is gradually generated between the second magnet 33 and the first magnet 370. This repulsive force can push the clamping member 34 downward during the secondary control of the bottom connecting rod 35 to move to the first position, so that it can separate from the positioning member 37, avoiding the situation where the positioning member 37 and the clamping member 34 are not separated, resulting in the bottom connecting rod 35 being unable to be positioned to the first position.

[0039] Additionally, it should be noted that the top of the bottom connecting rod 35 adopts a conical structure, and the bottom of the limiting member 32 adopts a wedge-shaped structure. Therefore, it is easier for the bottom connecting rod 35 to pass between the two limiting members 32, and it ensures that the two limiting members 32 will not be completely closed, thus preventing the rod from being difficult to insert.

[0040] In addition, the bottom of the bottom connecting rod 35 is provided with an assembly head 24. The assembly head 24 adopts a 1 / 4 spherical structure. The assembly hole 23 on the top of the mounting plate 22 adopts a groove structure that matches the assembly head 24, so that the assembly head 24 can rotate after being fitted into the assembly hole 23, thus facilitating the subsequent adjustment of the angle of the ceiling panel 11.

[0041] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. The scope of the present invention is intended to be defined by the claims and their equivalents.
