Description

Technical Field

[0001] This invention belongs to the field of ceiling technology, and particularly relates to a connection mechanism and ceiling device for translucent soft membrane ceilings. Background Technology

[0002] Translucent membrane ceilings, also known as stretch ceilings, decorative ceilings, tensile membrane ceilings, and flexible ceilings, are made of special PVC material. They are typically white with a light transmittance of around 80%, and are commonly used for decorative ceilings. Made from polyvinyl chloride chemicals, these ceilings have lower rigidity compared to traditional materials, requiring a more stable connection structure during installation.

[0003] Existing translucent stretch ceiling installations involve pre-installing a keel at the top of the wall, then connecting the stretch ceiling to the bottom of the connecting mechanism. This method achieves the installation layout of the translucent stretch ceiling. However, analysis of existing ceilings reveals that for typical home renovations, once installed, the ceiling is intended for many years of use, thus requiring permanent fixing until eventual damage and dismantling. But with the development and popularization of ceiling technology, more and more temporary structures (such as construction sites, offices, canteens, and rest rooms) are also being fitted with ceilings. For temporary rest rooms and offices, using translucent stretch ceilings can significantly enhance aesthetics and facilitate occupancy. To ensure comfort, if existing permanent ceiling connection structures (using expansion bolts, etc.) are still used, the ceiling cannot be disassembled when the building is not in use, resulting in waste. This is especially true for some temporary buildings that can be used multiple times, where the use of permanent ceiling connection structures has significant drawbacks. Moreover, some existing ceiling connection structures cannot adjust the height of the ceiling according to installation requirements during installation, often resulting in partial sagging of the ceiling during subsequent use. In such cases, because the connection structure does not have height adjustment capabilities, it is impossible to repair the ceiling. Therefore, given the above-mentioned problems, there is an urgent need to design a ceiling and connection structure that is easy to disassemble and can be reused. Summary of the Invention

[0004] The purpose of this invention is to provide a light-transmitting membrane ceiling connection mechanism and ceiling device, in order to solve the above-mentioned problems.

[0005] This invention is implemented as follows: A structural diagram of the connection mechanism for a translucent stretch ceiling includes: a translucent stretch ceiling body; multiple sets of detachable connection units evenly distributed on the top of the translucent stretch ceiling body; the top of each connection unit is detachably connected to a wall; each connection unit includes a lifting structure and a connection structure threaded to both ends of the lifting structure; the wall has a through hole with an outer opening, and the other end of the through hole connects to a positioning expansion groove with a diameter larger than the through hole diameter; a ceiling connection block is installed on the top of the translucent stretch ceiling body; the ceiling connection block has a through hole inside, and the bottom end of the through hole connects to a positioning expansion groove inside the translucent stretch ceiling body; the end of the connection structure furthest from the lifting structure passes through the through hole and engages with the positioning expansion groove, thereby achieving a detachable and stable connection between the connection structure, the translucent stretch ceiling body, and the wall; simultaneously, adjusting the height of the lifting structure adjusts the installation height of the translucent stretch ceiling body below it, adjusting and repairing the overall height or local sagging of the translucent stretch ceiling body;

[0006] When installing the translucent stretch ceiling body, according to the location of the ceiling connecting blocks on the top of the translucent stretch ceiling body, perforations and positioning expansion slots are made on the wall corresponding to the ceiling connecting blocks. Then, according to the height of the installation distance between the translucent stretch ceiling body and the wall, the connecting structures at both ends of the lifting structure are first inserted through the perforations and clipped into the positioning expansion slots on the wall and the translucent stretch ceiling body for positioning. Then, the height of the lifting structure is adjusted to limit the height of the translucent stretch ceiling body, realizing the cyclical use mode of disassembly installation and height adjustment and repair of the translucent stretch ceiling body.

[0007] The present invention also provides a translucent stretch ceiling device, comprising: an insertion mechanism installed on the side wall of the translucent stretch ceiling body, the insertion mechanism being inserted into a hole opened in the wall or the side wall of the translucent stretch ceiling body, the insertion mechanism including an insertion rod, one end of the insertion mechanism being connected to an adjusting screw, the end of the adjusting screw being threadedly connected to a threaded cylinder fixed on the side wall of the translucent stretch ceiling body, i.e., rotating the adjusting screw controls the length of the insertion rod, and then inserting it according to the position of the distance from the wall or the hole on the translucent stretch ceiling body, thereby stably installing the translucent stretch ceiling body on the wall in the lateral direction.

[0008] The present invention provides a translucent stretch ceiling connection mechanism and ceiling device. It involves pre-drilling interconnected perforations and positioning expansion slots on the translucent stretch ceiling body and the wall. Connecting units are then installed along the corresponding perforations on the upper and lower sides. The connecting structure inside each unit passes through the perforations and is positioned within the positioning expansion slot. A connecting screw and a connecting screw cylinder are then threaded together. A lifting structure connects the upper and lower connecting structures. Gear meshing restricts the extension and folding of the middle connecting rod, auxiliary connecting rod, and end connecting rod. This achieves a detachable connection between the translucent stretch ceiling body and the wall, while simultaneously stabilizing the structure by tightening the screw and locking the nut. The extension length of the lifting structure is controlled to adjust the installation height of the translucent stretch ceiling body from the top wall as needed. Furthermore, during subsequent use, the height of the upper lifting structure can be adjusted according to the sagging or collapse of the translucent stretch ceiling body, allowing for precise point-to-point repair and ensuring the long-term use of the translucent stretch ceiling body. The easy disassembly and reassembly of the lifting structure and connecting structure, along with the simple installation and removal methods between the connecting structure and the translucent stretch ceiling body and wall, facilitates the overall installation and removal or partial replacement and repair of the translucent stretch ceiling body. This allows for cyclical installation and removal of the translucent stretch ceiling body, realizing the recyclability of this device. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0017] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0018] like Figure 1 The diagram shown is a structural diagram of the light-transmitting stretch ceiling connection mechanism provided in an embodiment of the present invention. It includes: a light-transmitting stretch ceiling body 10; multiple sets of detachable connection units 11 evenly distributed on the top of the light-transmitting stretch ceiling body 10; the top of each connection unit 11 is detachably connected to a wall 49; each connection unit 11 includes a set of lifting structures 12 and connection structures 13 threadedly connected to both ends of the lifting structures 12; the wall 49 has a through hole 15 with an outer opening; the other end of the through hole 15 is connected to a positioning expansion groove 16 with a diameter larger than the diameter of the through hole 15; and a... The ceiling connecting block 14 has a through hole 15 inside. The bottom end of the through hole 15 is connected to a positioning expansion groove 16 opened inside the translucent soft membrane ceiling body 10. The end of the connecting structure 13 away from the lifting structure 12 passes through the through hole 15 and is snapped into the positioning expansion groove 16. This realizes a detachable and stable connection between the connecting structure 13 and the translucent soft membrane ceiling body 10 and the wall 49. At the same time, the height of the lifting structure 12 is adjusted to adjust the installation height of the translucent soft membrane ceiling body 10 below it, and the overall height or local sagging of the translucent soft membrane ceiling body 10 is adjusted and repaired.

[0019] During the installation of the translucent stretch ceiling body 10, according to the distribution of the ceiling connecting blocks 14 at the top of the translucent stretch ceiling body 10, through holes 15 and positioning expansion slots 16 are made on the wall 49 corresponding to the ceiling connecting blocks 14. Then, according to the installation height of the translucent stretch ceiling body 10 from the wall 49, the connecting structures 13 at both ends of the lifting structure 12 are first inserted through the through holes 15 and snapped into the positioning expansion slots 16 on the wall 49 and the translucent stretch ceiling body 10 for positioning. Then, the height of the lifting structure 12 is adjusted to limit the height of the translucent stretch ceiling body 10, realizing the cyclical use mode of disassembly installation and height adjustment and repair of the translucent stretch ceiling body 10.

[0020] In this embodiment of the invention, the exterior of the lifting structure 12, the connecting structure 13, and the ceiling connecting block 14 are all set to white. Since the translucent soft membrane ceiling body 10 has a light-transmitting effect when in use, setting the lifting structure 12, the connecting structure 13, and the ceiling connecting block 14 to white can reduce the impact on the light transmittance of the translucent soft membrane ceiling body 10.

[0021] like Figure 2-4In one embodiment of the present invention, the connecting structure 13 includes a positioning rod 30. One end of the positioning rod 30 is fixedly connected to a tapered rod 29. The tapered rod 29 facilitates its accurate passage through the through hole 15 and extension into the positioning expansion groove 16. The other end of the positioning rod 30 is fixedly connected to a positioning screw 35 with a diameter smaller than that of the positioning rod 30. A positioning nut 36 is threaded onto the positioning screw 35. A connecting plate 31 is fixedly installed at the end of the positioning screw 35 away from the positioning rod 30. The connecting plate 31 is connected to the lifting... Structure 12 features a detachable connection. The connecting plate 31 and positioning screw 35 have through holes along their axes. A tension positioning rod 38 is telescopically connected inside the through holes. A cavity is formed inside the positioning rod 30 facing the positioning screw 35. Multiple swing positioning rod slots 39 are evenly spaced in a ring on the outer side of the cavity. One end of the tension positioning rod 38 extends into the cavity, and a fixing collar 43 is installed on the circumferential side wall of its end. The fixing collar 43, corresponding to the position of each swing positioning rod slot 39, is oscillating outwards via a rotating rod 42 to connect to a swinging rod. The movable positioning rod 40 and the swing positioning rod 40 are elastically connected to a spring 41 whose bottom end is set on the outer wall of the tension positioning rod 38. By pushing the tension positioning rod 38 to move inside the through hole, the elastic action of the spring 41 and the contact blocking between the top of the swing positioning rod 40 and the side wall of the swing positioning rod slot 39 are used to control the swing positioning rod 40 to swing and retract in the direction of the tension positioning rod 38 toward the positioning insertion rod 30 or swing and tilt outwards away from the positioning insertion rod 30. The swing positioning rod 40 retracts to When inside the cavity, the positioning rod 30 extends through the through hole 15 into the positioning expansion groove 16. When the swing positioning rod 40 extends to the outside of the cavity, the unfolded end abuts against the side wall edge of the positioning expansion groove 16 facing the through hole 15, thereby preventing the positioning rod 30 from moving out along the through hole 15. The circular diameter formed by the multiple swing positioning rods 40 after unfolding is placed between the diameter of the through hole 15 and the diameter of the positioning expansion groove 16, ensuring that the swing positioning rod 40 can be unfolded inside the positioning expansion groove 16 and cannot be moved out from inside the through hole 15 after unfolding.

[0022] To accurately control the angle of the swing positioning rod 40 after it is extended to a reasonable range, that is, to ensure that the positioning rod 30 is prevented from detaching from the through hole 15 even after the swing positioning rod 40 swings to its maximum angle, a connecting rod 44 is connected to the end of the tension positioning rod 38 placed inside the cavity. A telescopic rod 45 is connected to the end of the connecting rod 44 away from the tension positioning rod 38. A telescopic groove 47 is opened at the end of the telescopic rod 45 corresponding to the inside of the positioning rod 30. An anti-telescopic rod is installed at the end of the telescopic rod 45 placed inside the telescopic groove 47. The limiting block 46, which detaches from the inside of the telescopic groove 47, ensures that the maximum moving distance of the telescopic rod 45 is equal to the depth of the telescopic groove 47. That is, the moving distance of the stretching positioning rod 38 is also equal to the depth of the telescopic groove 47. By pre-setting the depth of the telescopic groove 47 and the length of the swing positioning rod slot 39, it is ensured that the swing positioning rod 40 can be fully retracted into the cavity and swing to the outside of the swing positioning rod slot 39 to abut against the inner end side wall of the perforation 15 when it moves with the stretching positioning rod 38.

[0023] A spring 48 is fitted on the telescopic rod 45, which is located between the connecting rod 44 and the telescopic groove 47. When the spring 48 is in a free telescopic state, the control limit block 46 is close to the side of the telescopic groove 47 facing the connecting rod 44, that is, it keeps the swing positioning rod 40 in the state of swinging outward to the maximum angle. When the swing positioning rod 40 is at the maximum swing angle, its top is restricted by the contact of the top side wall of the swing positioning rod groove 39, which further maintains the temperature of the swing positioning rod 40 after swinging to the maximum angle.

[0024] In a preferred embodiment of the present invention, after the swing positioning rod 40 is extended, it abuts against the side wall of the positioning expansion groove 16 facing the perforation 15. At this time, the connecting plate 31 on the translucent soft membrane ceiling body 10 and the connecting plate 31 on the lower side of the wall 49 are both subjected to downward gravity from the translucent soft membrane ceiling body 10. At this time, by rotating the positioning nut 36, it is moved towards the outer side wall of the perforation 15, thereby fixing the positioning rod 30. The same operation steps are required to disassemble the positioning rod 30 from the perforation 15 and the positioning expansion groove 16. First, rotate the positioning nut 36 away from the side of the perforation 15, and then apply a pushing force towards the inside of the positioning expansion groove 16 to the stretch positioning rod 38, so that multiple sets of swing positioning rods 40 swing and are stored in the cavity. At this time, the positioning rod 30 can be output along the perforation 15. In this way, through the above structure and simple operation, multiple cycles of disassembly and installation between the connecting structure 13 and the wall 49 and the translucent soft membrane ceiling body 10 can be realized, improving the disassembly and assembly capability of this connecting mechanism.

[0025] In a preferred embodiment of the present invention, a push block 37 is installed on the outer end of the tension positioning rod 38 to facilitate the operator to control the movement of the tension positioning rod 38. Two connecting screws 32 are symmetrically connected to the connecting plate 31 at the outer end of the tension positioning rod 38 via bearings 33. The connecting screws 32 are detachably connected to the lifting structure 12.

[0026] like Figure 5-6 In a preferred embodiment of the present invention, the lifting structure 12 includes a central connecting rod 17, with auxiliary connecting rods 18 and end connecting rods 19 symmetrically rotatably arranged on both sides of the central connecting rod 17. A "human" shaped connector is rotatably connected between the middle of the central connecting rod 17, the auxiliary connecting rod 18, and the end connecting rod 19. A two-section connecting rod with an "I" shaped structure is rotatably connected between the ends of the central connecting rod 17, the auxiliary connecting rod 18, and the end connecting rod 19. By cooperating and rotating between the connector and the connecting rod, the extension and folding of the central connecting rod 17, the auxiliary connecting rod 18, and the end connecting rod 19 are controlled, thereby adjusting the overall height of the lifting structure 12. This is used to adjust the distance between the translucent soft membrane ceiling body 10 and the wall 49, and to repair the partially sagging translucent soft membrane ceiling body 10.

[0027] The connecting components include swing rod II 24, swing rod III 25, and swing rod IV 26; one end of each swing rod II 24, swing rod III 25, and swing rod IV 26 is rotatably connected together, the other end of swing rod II 24 is rotatably connected to the middle connecting rod 17, the other end of swing rod III 25 is rotatably connected to the end connecting rod 19, and the other end of swing rod IV 26 is rotatably connected to the auxiliary connecting rod 18. Meanwhile, the lengths of the swing rod III 25, swing rod IV 26, and swing rod II 24 increase sequentially.

[0028] The two-section connecting rod includes two swing rods I23, which are rotatably connected. The connection point of the two swing rods I23 is rotatably connected to an auxiliary connecting rod 18. The other ends of the two swing rods I23 are respectively rotatably connected to a middle connecting rod 17 and an end connecting rod 19. When the middle connecting rod 17, the auxiliary connecting rod 18, and the end connecting rod 19 extend, they move relative to each other. Simultaneously, the auxiliary connecting rod 18 moves towards either the middle connecting rod 17 or the end connecting rod 19. Furthermore, when the middle connecting rod 17, the auxiliary connecting rod 18, and the end connecting rod 19 are folded, the common connecting end of the two swing rods I 23 and the common connecting end of the swing rods II 24, III 25, and IV 26 move synchronously in the direction along the length of the auxiliary connecting rod 18 to maintain the stable folding of the middle connecting rod 17, the auxiliary connecting rod 18, and the end connecting rod 19. Similarly, when the middle connecting rod 17, the auxiliary connecting rod 18, and the end connecting rod 19 are unfolded, the above-mentioned movement along the opposite path or direction can be achieved.

[0029] In a preferred embodiment of the present invention, in order to ensure that the lifting structure 12 remains stable after extending and adjusting its height, and to accurately control the adjustment size, gears 22 are installed at the ends of the swing rods I 23 located at both ends of the middle connecting rod 17. The gears 22 on both sides mesh with each other. A connecting rod that moves through the middle of the gears 22 to the other side of the middle connecting rod 17 is connected to the middle of the gears 22. A fastening screw 27 is installed at the end of the connecting rod, and a locking nut 28 is threaded onto the fastening screw 27. By utilizing the meshing between the gears 22, the end of the swing rod I 23 is controlled by the gears 22 when rotating, so that the height of the lifting structure 12 can be adjusted to any position. By setting four sets of locking nuts 28 and fastening screws 27 to rotate, the stability of the middle connecting rod 17, auxiliary connecting rod 18, and end connecting rod 19 after stopping can be fully and stably controlled.

[0030] In a preferred embodiment of the present invention, fixing blocks 20 are installed on both sides of the side wall of the end connecting rod 19, and connecting screws 21 are installed on the fixing blocks 20. The connecting screws 21 and the connecting screw cylinder 32 are threadedly connected. Since the connecting screw cylinder 32 is rotatably connected to the connecting plate 31 through the bearing 33, the connecting screw cylinder 32 can be directly rotated when controlling the connection between the connecting screw cylinder 32 and the connecting screw 21.

[0031] like Figure 1-6 As shown, the translucent stretch ceiling device also provided in this embodiment of the invention includes: an insertion mechanism 50 installed on the side wall of the translucent stretch ceiling body 10, the insertion mechanism 50 being inserted into a hole opened in the wall 49 or the side wall of the translucent stretch ceiling body 10, the insertion mechanism 50 including an insertion rod 51, one end of the insertion mechanism 50 being connected to an adjusting screw, the end of the adjusting screw being threadedly connected to a threaded cylinder fixed on the side wall of the translucent stretch ceiling body 10, that is, rotating the adjusting screw controls the length of the insertion rod 51, and then inserting it according to the position of the distance from the wall 49 or the hole on the translucent stretch ceiling body 10, thereby stably installing the translucent stretch ceiling body 10 on the wall 49 in the lateral direction.

[0032] The above embodiments of the present invention provide a translucent stretch ceiling connection mechanism, and based on this translucent stretch ceiling connection mechanism, a translucent stretch ceiling device is provided. Through-holes 15 and positioning expansion slots 16 are pre-opened on the translucent stretch ceiling body 10 and the wall 49, which are interconnected. Then, connecting units 11 are installed between the corresponding upper and lower through-holes 15. The connecting structure 13 inside the connecting unit 11 passes through the through-holes 15 and is positioned in the positioning expansion slots 16. Then, a connecting screw 21 is threadedly connected to a connecting screw 32. A lifting structure 12 connects the upper and lower connecting structures 13. Finally, the meshing of gears 22 restricts the extension and folding of the middle connecting rod 17, auxiliary connecting rod 18, and end connecting rod 19, thus enabling disassembly between the translucent stretch ceiling body 10 and the wall 49. While connecting the two structures, the extension length of the lifting structure 12 is stably controlled by the fastening screw 27 and locking nut 28. This allows for adjustment of the installation height of the translucent stretch ceiling body 10 from the top wall 49 as needed. Furthermore, during subsequent use, the height of the lifting structure 12 can be adjusted according to the sagging or collapse of the translucent stretch ceiling body 10, enabling precise point-to-point repair and ensuring the long-term use of the translucent stretch ceiling body 10. The easy disassembly and reassembly of the lifting structure 12 and connecting structure 13, along with the simple installation and disassembly method between the connecting structure 13 and the translucent stretch ceiling body 10 and wall 49, facilitates the overall installation and disassembly or partial replacement and repair of the translucent stretch ceiling body 10. This allows for cyclical installation and disassembly of the translucent stretch ceiling body 10, realizing the recyclability of this device.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
