Description

Technical Field

[0001] This invention relates to the field of ceiling installation technology, and more specifically, to a snap-fit ​​structure for a quick-installation concealed ceiling panel for integrated bathrooms. Background Technology

[0002] As a core space in modern architecture that combines practicality and aesthetics, the design and performance of the ceiling system in a prefabricated bathroom directly impacts the living experience and spatial quality. The ceiling system not only needs to fulfill its basic functions of concealing internal pipes and optimizing the visual effect of the space, but also needs to adapt to the complex conditions unique to bathroom environments, such as humidity, diurnal temperature fluctuations, and equipment vibrations. Furthermore, as people's demands for living quality continue to rise, the comprehensive performance of ceiling panels, including thermal insulation, sound insulation, lightweight design, and structural strength, has become a core focus of the industry. Against this backdrop, rock wool core materials and aluminum honeycomb core materials, with their superior performance, are gradually replacing traditional materials and becoming the mainstream choice for modern prefabricated bathroom ceiling panels, driving the development of ceiling systems towards greater efficiency and durability.

[0003] However, traditional integrated bathroom ceiling panels and mounting joists often use simple slots and clips for connection. This method requires multiple people to work together, forcibly squeezing the panels to fix them to the joists, making the process cumbersome and physically demanding. In the confined space of a bathroom, this installation method is not only inefficient but also prone to insufficient installation precision due to limited space, affecting the overall flatness of the ceiling. More importantly, this forced clamping method causes irreversible damage to the main core materials: for rock wool core materials, uneven compression can directly damage the integrity of its internal fiber structure, leading to a significant decrease in core performance such as heat insulation and sound insulation; for aluminum honeycomb core materials, localized concentrated stress may cause deformation and collapse of the honeycomb cells, preventing the full utilization of its lightweight and high-strength structural advantages, thus weakening the overall load-bearing capacity of the ceiling panel and creating safety hazards.

[0004] The problems with traditional snap-fit ​​structures are even more pronounced during later maintenance and disassembly. When a single ceiling panel needs replacement due to damage from long-term use, or when pipes and equipment inside the ceiling need to be inspected, the clips and strips, which have been locked together under stress for a long time, are prone to becoming too tightly interlocked, making separation extremely difficult. In this case, users often need to use tools to pry it open forcibly, which not only consumes a lot of manpower but also easily causes secondary damage such as breakage of the ceiling panel edges and deformation of the clips. More seriously, forced disassembly may affect the stability of surrounding ceiling panels, triggering a chain reaction that causes more ceiling panels to loosen or even fall off, further increasing maintenance costs and safety risks. Summary of the Invention

[0005] To address the problems mentioned in the background art, this invention provides a quick-installation concealed ceiling panel snap-fit ​​structure for integrated bathrooms, comprising multiple ceiling panels and mounting joists. The multiple ceiling panels are spliced ​​in multiple rows and columns, with two adjacent ceiling panels in each row symmetrically arranged on both sides of the mounting joists. The top surface of each ceiling panel is fixedly connected to symmetrically distributed side mounting plates. Each side of the mounting joists has a first mounting groove. Inside each first mounting groove is a first component for controlling the locking and unlocking state of the ceiling panels by pushing them. The first component includes a support plate slidably disposed inside the first mounting groove. A downwardly inclined limiting plate is fixedly connected to the side of the support plate near the side mounting plate. An abutment plate is fixedly connected to the side of the side mounting plate near the mounting joists, and the abutment plate abuts against the limiting plate. A sliding plate is also slidably disposed on the side of the side mounting plate near the mounting joists, and the sliding plate is disposed below the abutment plate.

[0006] Furthermore, the side mounting plate has several linearly arranged sliding grooves on the side near the mounting keel, and several linearly arranged sliders are fixedly connected to the side of the sliding plate near the side mounting plate, and the sliders are slidably connected to the sliding grooves.

[0007] Furthermore, several second sliding grooves arranged in a linear array are provided on both the upper and lower sides of the inner wall of the first mounting groove. Several second sliders arranged in a linear array are fixedly connected to the top of the support plate and the bottom of the limiting plate. The second sliders are slidably connected to the second sliding grooves. Several return springs arranged in a linear array are fixedly connected between the side of the support plate away from the side mounting plate and the inner wall of the first mounting groove.

[0008] Furthermore, the side of the contact plate closest to the mounting keel is inclined downwards, the side of the limiting plate closest to the mounting plate is inclined upwards, the cross-sectional shape of the sliding plate is an isosceles trapezoid, and both the side of the sliding plate closest to the contact plate and the side furthest from the contact plate are inclined surfaces.

[0009] Furthermore, a second mounting groove is provided at the bottom of the mounting keel, and a second component for shock absorption of the ceiling panel in the connected state is provided inside the second mounting groove.

[0010] Furthermore, the second component includes a crossbar detachably connected inside the second mounting slot, and two symmetrically distributed third sliders are slidably connected to the outside of the crossbar, with a shock-absorbing spring fixedly connected between the two third sliders.

[0011] Furthermore, a rotating rod is rotatably connected to the bottom of the third slider, and a positioning block is rotatably connected to the bottom of the rotating rod. Four rectangularly distributed positioning frames are fixedly connected to the top of the ceiling panel. The positioning blocks are made of magnets, and another magnet is provided in the inner bottom cavity of the positioning frame. The positioning blocks and positioning frames are magnetically connected.

[0012] Furthermore, two No. 3 sliding grooves are provided on both sides of the inner wall of the No. 2 mounting groove, and a No. 4 sliding groove is provided on both sides of the inner wall of the No. 2 mounting groove. The No. 3 sliding groove and the No. 4 sliding groove are connected, and the No. 3 slider is slidably connected to the No. 3 sliding groove and the No. 4 sliding groove.

[0013] Furthermore, when the ceiling panel is connected to the mounting keel, the shock-absorbing spring is in a stretched state.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention optimizes the inclined structure of the contact plate, limiting plate, and sliding plate, and, in conjunction with the elastic reset function of the return spring, achieves quick installation and removal of the ceiling panel and the mounting joists. During installation, no multiple people are needed to forcefully press; a single person can easily lock it by pushing upwards. Similarly, disassembly is achieved by simply pushing up and down, without the need for specialized tools. This design not only simplifies the operation process and improves installation and maintenance efficiency, but also precisely controls installation accuracy, ensuring the overall flatness of the ceiling. It effectively solves the pain points of cumbersome and inefficient installation of traditional snap-fit ​​structures, perfectly meeting the needs of efficient construction in modern integrated bathroom projects.

[0015] 2. The second component of this invention, through the synergistic effect of the shock-absorbing spring, the rotating rod and the third slider, can effectively absorb the vibration energy generated by the operation of equipment in the bathroom space, weaken the vibration transmission, and achieve a good shock absorption effect on the ceiling panel, ensuring the stability of the connection between the ceiling panel and the installation keel.

[0016] 3. In this invention, the shock-absorbing spring is always in a stretched or compressed state after installation. The elastic tension it generates is transmitted to the ceiling panel through the rotating rod and positioning block, ensuring that the contact plate and the limiting plate always maintain close contact, preventing vibration from causing the connection to loosen, ensuring structural stability, and allowing the ceiling system to maintain a good condition during long-term use, providing users with a safe, comfortable and stable user experience.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides a snap-fit ​​structure for a quick-installation concealed ceiling panel for integrated bathrooms. See [link / reference]. Figure 1 As shown, the system includes multiple ceiling panels 1 and mounting joists 2. The ceiling panels 1 are arranged in multiple rows and columns. Two adjacent ceiling panels 1 in each row are symmetrically arranged on both sides of the mounting joists 2. The top surface of each ceiling panel 1 is fixedly connected to symmetrically distributed side mounting plates 11. Each side of the mounting joists 2 has a first mounting groove 21. The first mounting groove 21 is equipped with a first component 3 for controlling the locking and unlocking state of the mounting joists 2 on the ceiling panels 1 by pushing the ceiling panels 1. The first component 3 includes components that are slidably disposed in the first mounting groove 21. The internal support plate 31 has an inclined limiting plate 32 fixedly connected to the side of the support plate 31 near the side mounting plate 11. The side mounting plate 11 has a downwardly inclined abutment plate 12 fixedly connected to the side of the mounting keel 2. The abutment plate 12 abuts against the limiting plate 32. The limiting plate 32 and the support plate 31 form a hanging plate, thereby engaging with the abutment plate 12 on the side of the side mounting plate 11. A sliding plate 13 is also slidably provided on the side of the side mounting plate 11 near the mounting keel 2. The sliding plate 13 is located below the abutment plate 12.

[0021] See Figure 2 As shown, when the ceiling panel 1 and the mounting keel 2 are locked, the bottom surface of the limiting plate 32 abuts against the bottom surface of the contact plate 12. At this time, the ceiling panel 1 is connected to the mounting keel 2 through the contact between the contact plate 12 and the limiting plate 32, and the limiting plate 32 supports the ceiling panel 1. In actual installation, ceiling panels 1 are installed on both sides of one mounting keel 2, and the two sides of the ceiling panel 1 are connected to two parallel mounting keels 2. The mounting keels 2 are detachably installed to the ceiling in the bathroom through screws or other connectors.

[0022] Furthermore, the side mounting plate 11 has several linearly arranged first slide grooves 15 on the side near the mounting keel 2. The sliding plate 13 is fixedly connected to several linearly arranged first sliders 14 on the side near the side mounting plate 11. The first sliders 14 are slidably connected to the first slide grooves 15. The lower end of the first slide groove 15 does not penetrate the bottom of the side mounting plate 11, so that the first sliders 14 can move up and down stably in the first slide groove 15, and the first sliders 14 do not separate from the first slide groove 15. In order to ensure the stable sliding of the first sliders 14 and the first slide groove 15, both the first sliders 14 and the first slide groove 15 are dovetail-shaped, so that the sliding plate 13 can slide up and down stably along the side of the side mounting plate 11. The upper and lower sides of the inner wall of the first mounting groove 21 are provided with several second sliding grooves 22 arranged in a straight line. The top of the support plate 31 and the bottom of the limiting plate 32 are fixedly connected with several second sliders 34 arranged in a straight line. The second sliders 34 are slidably connected to the second sliding grooves 22. Several return springs 33 arranged in a straight line are fixedly connected between the side of the support plate 31 away from the side mounting plate 11 and the inner wall of the first mounting groove 21. The return springs 33 apply elastic force to the support plate 31.

[0023] See Figure 3 and Figure 4 As shown, through the sliding engagement of slider 14 and slide groove 15, slide plate 13 can slide vertically up and down on side mounting plate 11. Through the sliding engagement of slide groove 22 and slider 34, support plate 31 can move horizontally within mounting groove 21. In the initial state when ceiling plate 1 and mounting keel 2 are not connected, slider 34 is located inside slide groove 22 on the side close to mounting plate 11, and the return spring 33 is in a relaxed state.

[0024] Furthermore, the side of the contact plate 12 closest to the mounting keel 2 is inclined downwards, the side of the limiting plate 32 closest to the side mounting plate 11 is inclined upwards, the cross-sectional shape of the sliding plate 13 is an isosceles trapezoid, and both the side of the sliding plate 13 closest to the contact plate 12 and the side furthest from the contact plate 12 are inclined surfaces. The distance between the side of the contact plate 12 furthest from the side mounting plate 11 and the side mounting plate 11 is less than the distance between the side of the sliding plate 13 furthest from the side mounting plate 11 and the side mounting plate 11.

[0025] When installing ceiling panel 1, the user can first align ceiling panel 1 with the mounting keel 2, and then push ceiling panel 1 upward by hand. Under the action of the top inclined surface of the contact plate 12 and the bottom inclined surface of the limiting plate 32, the contact plate 12 will push the limiting plate 32 and the support plate 31 to slide towards the inside of the first mounting groove 21 until the contact plate 12 completely passes through the limiting plate 32. At this time, the contact plate 12 no longer applies a pushing force to the limiting plate 32, and the return spring 33 releases its elastic force to reset the support plate 31 and the limiting plate 32. At this time, slowly release the upward pushing force on ceiling panel 1. Under the action of the weight of ceiling panel 1, the side mounting plate 11 and the contact plate 12 move downward. The top inclined surface of the limiting plate 32 will abut against the bottom inclined surface of the contact plate 12. The limiting plate 32 and the support plate 31 realize the supporting function of the contact plate 12 and the side mounting bracket, thereby completing the installation and positioning of ceiling panel 1. When it is necessary to remove the ceiling panel 1, the user can push the ceiling panel 1 upward again, so that the top slope of the sliding plate 13 touches the bottom surface of the limiting plate 32. Similarly, the limiting plate 32 and the support plate 31 will slide into the first mounting groove 21 again. After the sliding plate 13 has completely passed the limiting plate 32, the user can remove the pushing force on the ceiling panel 1 and instead lift the ceiling panel 1 by hand to lower the ceiling panel 1. Specifically, the ceiling panel 1 can be attached to the bottom of the ceiling panel 1 by suction cup, and the ceiling panel 1 can be moved downward by pulling the suction cup downward. During this process, the bottom slope of the sliding plate 13 will contact the limiting plate 32. Since the sliding plate 13 slides in the first groove 15 through the first slider 14, the sliding plate 13 cannot move down synchronously with the side mounting plate 11 under the resistance of the limiting plate 32. At this time, the abutting plate 12 gradually moves closer to the sliding plate 13 until the top slope of the sliding plate 13 abuts the bottom slope of the abutting plate 12. Then, under the limiting action of the abutting plate 12, the abutting plate 12 will push the sliding plate 13 to move down synchronously when it moves down. During the continuous descent of the ceiling plate 1, the abutting plate 12 and the sliding plate 13 together push the limiting plate 32 and the support plate 31 to enter the first mounting groove 21 again. Since the sliding plate 13 and the abutting plate 12 are tightly attached together, the limiting plate 32 can no longer engage with the abutting plate 12, thereby achieving the effect of giving way to the sliding plate 13 and the abutting plate 12, so that the abutting plate 12 moves to the bottom of the limiting plate 32, and the disassembly of the ceiling plate 1 is completed.

[0026] It should be noted that, see Figure 2 As shown, the inclination angles of the contact plate 12, sliding plate 13, and limiting plate 32 are the same, and the inclined surfaces can fit together when they are in contact with each other. When the limiting plate 32 and the supporting plate 31 give way to the sliding plate 13 and the contact plate 12, the side of the limiting plate 32 always abuts against the bottom surface of the sliding plate 13. While the limiting plate 32 gives way, it can ensure that the sliding plate 13 and the contact plate 12 always fit together. In this way, as the ceiling panel 1 continues to descend, the contact plate 12 and the sliding plate 13 can pass through the limiting plate 32 together until the ceiling panel 1 is completely separated from the mounting keel 2.

[0027] On the other hand, a second mounting groove 23 is provided at the bottom of the mounting keel 2. The second mounting groove 23 is provided with a second component 4 for shock absorption of the ceiling panel 1 in the connected state, and the second component 4 makes the contact plate 12 and the limiting plate 32 in close contact.

[0028] Furthermore, component 4 includes a crossbar 41 detachably connected inside mounting slot 23. Two symmetrically distributed sliders 42 are slidably connected to the outside of the crossbar 41, and a shock-absorbing spring 43 is fixedly connected between the two sliders 42.

[0029] Furthermore, a rotating rod 44 is rotatably connected to the bottom of slider 42, and a positioning block 45 is rotatably connected to the bottom of the rotating rod 44. Four rectangularly distributed positioning frames 16 are fixedly connected to the top of the ceiling panel 1. The positioning blocks 45 are made of magnets, and another magnet is fixedly connected to the bottom of the inner cavity of the positioning frame 16. The positioning blocks 45 and the positioning frames 16 are magnetically connected internally. The magnetic poles of the sides of the positioning blocks 45 and the positioning frames 16 that are close to each other are opposite. When installing the ceiling panel 1, the magnetic attraction between the positioning blocks 45 and the positioning frames 16 can complete the initial positioning of the ceiling panel 1 and the mounting keel 2. When the ceiling panel 1 and the mounting keel 2 are connected, the shock-absorbing spring 43 is in a stretched state.

[0030] Since exhaust fans are often installed above the ceiling panel 1 in bathrooms, the operation of the exhaust fan causes the ceiling panel 1 to vibrate. At this time, component 4 acts as a shock absorber for the ceiling panel 1. Specifically, when the ceiling panel 1 vibrates, it applies a vibrational force to the rotating rod 44. The rotating rod 44 transmits the vibrational force to the slider 42. The rotating rod 44 rotates during vibration, and the slider 42 moves along the crossbar 41 under the vibrational force and the rotation of the rotating rod 44, thereby compressing or stretching the shock-absorbing spring 43. The shock-absorbing spring 43 generates elastic force to buffer the vibrational force of the slider 42, thus achieving the shock absorption effect of the ceiling panel 1.

[0031] When the ceiling panel 1 and the mounting keel 2 are connected, the rotating rod 44 deflects due to the distance limitation between the top surface of the ceiling panel 1 and the bottom surface of the mounting keel 2. (See below) Figure 5 As shown, the shock-absorbing spring 43 is in a stretched state. At this time, the elastic force of the shock-absorbing spring 43 will tend to push the ceiling panel 1 downward. When the ceiling panel 1 is connected to the mounting keel 2, the bottom surface of the contact plate 12 will contact the top surface of the limiting plate 32 more tightly, thereby stabilizing the ceiling panel 1. At the same time, the tight contact between the contact plate 12 and the limiting plate 32 can further prevent the airflow from passing through the gap between the contact plate 12 and the limiting plate 32 when the exhaust fan is started, thereby further reducing the vibration of the ceiling panel 1 and improving the noise reduction effect of the first component 3 and the second component 4.

[0032] Further, see Figure 6 As shown, two No. 3 sliding grooves 24 are opened on both sides of the inner wall of the No. 2 mounting groove 23, and a No. 4 sliding groove 25 is opened on both sides of the inner wall of the No. 2 mounting groove 23. The No. 3 sliding groove 24 and the No. 4 sliding groove 25 are connected, and the No. 3 slider 42 is slidably connected to the No. 3 sliding groove 24 and the No. 4 sliding groove 25.

[0033] When assembling component 4 into mounting slot 23, the user first pushes the rotating rod 44 to bring the two sliders 42 closer together until the distance between the sliders 42 matches the distance between the two slide grooves 24. Then, the user inserts the crossbar 41 into mounting slot 23 and pushes the two sliders 42 into mounting slot 23 through slide grooves 24 until the sliders 42 enter slide groove 25. Then, the user releases the rotating rod 44, and the sliders 42 slide into slide groove 25 under the force of the damping spring 43.

[0034] It should be noted that when the damping spring 43 is in the relaxed state, the distance between the two third sliders 42 is greater than the distance between the two third slide grooves 24. Even if vibration may cause the damping spring 43 to contract slightly, the two third sliders 42 will not enter the third slide groove 24 from the fourth slide groove 25.

[0035] The working principle of this device is as follows: by Figure 1 — Figure 6For example, when installing the ceiling panel 1 and the keel 2, the user first fixes the keel 2 to the ceiling using screws and other connectors. Then, the user uses a suction cup to attach the ceiling panel and holds the suction cup and ceiling panel 1 by hand. The user uses the magnetic attraction between the positioning block 45 and the magnet inside the positioning frame 16 to complete the initial positioning and ensure accurate connection. Subsequently, the user pushes the ceiling panel 1 upward, causing the side mounting plate 11 and the contact plate 12 to move synchronously. The top slope of the contact plate 12 contacts the bottom slope of the limiting plate 32, generating a resistance force. This force is decomposed into a horizontal driving force, pushing the limiting plate 32 and the support plate 31 to slide into the first mounting groove 21. The return spring 33 is compressed and stored as elastic potential energy. Once the contact plate 12 has completely passed the limiting plate 32, the contact plate 12 no longer exerts any resistance force on the limiting plate 32. The return spring 33 releases its elastic potential energy, pushing the support plate 31 and the limiting plate 32 back to their original positions along the second slide groove 22. The top inclined surface of the limiting plate 32 and the bottom inclined surface of the contact plate 12 are tightly fitted together, and stable support is obtained through the support plate 31. This achieves reliable locking and support for the contact plate 12, the side mounting plate 11, and the ceiling plate 1, completing the installation. At this time, the rotating rod 44 deflects under the gravity of the ceiling plate 1, driving the third slider 42 to move along the crossbar 41, causing the shock-absorbing spring 43 to be in a stretched state. Its elastic force is transmitted to the ceiling plate 1 through the rotating rod 44 and the positioning block 45, making the contact plate 12 and the limiting plate 32 fit more tightly and enhancing the connection stability.

[0036] When the bathroom fixtures vibrate during operation, the vibration energy is transmitted through the ceiling panel 1 to the positioning frame 16, and then through the magnetically connected positioning block 45 to the rotating rod 44. Under the influence of the vibration, the rotating rod 44 rotates reciprocally, causing the third slider 42 to move horizontally along the crossbar 41 and the third and fourth slide grooves 24 and 25. This causes the damping spring 43 to alternately stretch and compress, absorbing the vibration energy through elastic deformation and converting kinetic energy into elastic potential energy before releasing it. This effectively weakens the vibration transmitted to the ceiling panel 1, preventing collisions and abnormal noises. Simultaneously, the elastic tension of the damping spring 43 always acts on the third slider 42, applying a stabilizing force to the ceiling panel 1 through the rotating rod 44, ensuring that the contact plate 12 and the limiting plate 32 are always in close contact, preventing the connection from loosening due to vibration.

[0037] When disassembling ceiling panel 1, the user first pushes the ceiling panel 1 upwards, causing the side mounting plate 11 and sliding plate 13 to move upwards simultaneously. The top slope of the sliding plate 13 contacts the bottom surface of the limiting plate 32, generating a resistance force, which is decomposed into a horizontal driving force that pushes the limiting plate 32 and the support plate 31 to slide back into the first mounting slot 21. The return spring 33 contracts and stores energy. After the sliding plate 13 has completely passed the limiting plate 32, the user removes the upward pushing force and lifts the ceiling panel 1 to slowly descend. During the descent, the bottom slope of the sliding plate 13 contacts the limiting plate 32, and the continuous descent of the ceiling panel 1 causes the contact plate 12 to gradually approach the sliding plate 13 until the bottom surface of the contact plate 12 is completely in contact with the top surface of the sliding plate 13. As the ceiling panel 1 continues to descend, the contact plate 12 and the sliding plate 13 together exert downward pressure on the top slope of the limiting plate 32, which is decomposed into a horizontal driving force to push the limiting plate 32 and the support plate 31 to slide into the first mounting slot 21 again, providing space for the contact plate 12 and the sliding plate 13 to descend until they completely pass the limiting plate 32, at which point the user can smoothly remove the ceiling panel 1.
