Description

Technical Field

[0001] The present invention relates to the technical field of suspended ceilings, and in particular to an assembled suspended ceiling. Background Art

[0002] Suspended ceilings are suitable for rooms with high ceilings. They primarily serve a decorative purpose, making the interior of the room appear less empty and facilitating the layout of related wiring. They also provide a certain degree of insulation and sound insulation. A modular, prefabricated ceiling system is a prefabricated ceiling system composed of multiple components or modules, such as several ceiling panels, that can be quickly installed into a building's interior space using connectors. Such a ceiling system also includes decorative design elements.

[0003] Most existing prefabricated ceiling cover installations often use methods such as bolt tightening and slot hard connection. During the installation process, each component needs to be precisely aligned, and the installation accuracy requirements are extremely high. In addition, when installing or removing the cover, the operation is difficult and requires the cooperation of multiple people, which can easily cause damage to the cover and the frame. Taking the common integrated ceiling as an example, when installing the cover, the cover must be carefully inserted into the slot. If there is a slight deviation, it will be difficult to install in place, and during later maintenance and disassembly, the cover can easily break due to uneven force. In addition, existing prefabricated ceilings are mostly sealed with sealing strips or sealants, which cannot cope with the slight displacement and deformation that may occur in the use of the ceiling. When the ceiling is subjected to external vibrations or impacts, such as vibrations caused by decoration upstairs, the sealing strips or sealants cannot absorb the vibration energy, which will cause the ceiling to produce loud noises, affecting the comfort of the indoor environment.

[0016] The beneficial effects of the present invention are: 1. This device adopts modular installation. Through the sliding cooperation of the unique positioning component and the mounting guide rail, the separation or engagement of the positioning block and the slide groove can be controlled by pulling the pull plate. It can be operated by one person and does not require additional tools, which greatly simplifies the installation process of the sealing unit. Compared with the traditional ceiling installation, it abandons the tedious on-site assembly steps, significantly improves the construction efficiency, and reduces the labor cost investment; the ball bearings that rotate and engage the outer side of the positioning block reduce the friction between the slide groove, making the sealing unit slide more smoothly on the mounting guide rail, further accelerating the installation speed and improving the convenience of the assembly operation; and when the sealing unit is installed, the annular airbag is in a saturated state and is elastic.

It can effectively prevent dust, moisture, etc. from entering the interior of the ceiling, protect the ceiling structure and equipment, and improve the sealing and overall performance of the ceiling. When the ceiling is subjected to external vibrations or impacts of objects, such as vibrations caused by decoration upstairs, the sealing strips or sealants cannot absorb the vibration energy, which will cause the ceiling to produce loud noises and affect the comfort of the indoor environment. The present application uses the annular airbag to have elasticity in a saturated state. When the sealing unit moves or is subjected to external vibrations, it can absorb and disperse external forces, reduce rigid collisions, reduce noise, and improve the user experience.

[0018] 3. When there is a problem with the sealing unit, the existing technology, such as bolt tightening, is cumbersome to disassemble and requires tools. However, this device only needs to pull the pull plate to disengage the positioning block from the slide slot, and the sealing unit can be easily disassembled for maintenance or replacement. The operation is simple and convenient, which reduces maintenance costs and time and improves the convenience of later maintenance of the ceiling. With modular installation, each sealing unit is independent and a single sealing unit can be replaced at will without considering module compatibility issues. Compared with the limited module versatility and interchangeability in the existing technology, the maintenance difficulty is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0023] Example 1, refer to Figures 1-13 , an assembled ceiling, including a grid frame 2, a hanger 4 and a plurality of closing plate units 1, a connecting piece 41 is installed on the upper side of the grid frame 2, the grid frame 2 is connected to the hanger 4 through the connecting piece 41, and the hanger 4 plays a supporting role, transferring the weight of the ceiling to the building structure, and a plurality of grid spaces are arranged and distributed on the grid frame 2. The closing plate unit 1 is arranged in the grid space, which can realize modular installation, improve installation efficiency, and facilitate later maintenance and replacement. The lower side of the grid frame 2 is connected with a sealing edge 21, which not only beautifies the appearance of the ceiling, but also protects the closing plate unit 1 and the mounting guide rail 3 to prevent them from being collided and damaged. The bottom of the closing plate unit 1 is provided with a base plate 11, and the front and rear sides of the base plate 11 are flush with the front and rear sides of the closing plate unit 1, and its left and right sides extend to the outside of the left and right sides of the closing plate unit 1. It also includes: Mounting rail 3: The mounting rail 3 is installed inside the space enclosed by the lower side of the grille frame 2 and the edge sealing 21; Positioning assembly: The positioning assembly is arranged on the base plate 11. The sealing unit 1 forms a sliding fit with the mounting guide rail 3 through the positioning assembly, which facilitates the installation and removal of the sealing unit 1. During the installation process, it can be positioned quickly and accurately, thereby improving the construction efficiency. Sealing unit: The sealing unit is arranged inside the base plate 11, which can effectively prevent dust, moisture, etc. from entering the interior of the ceiling, protect the ceiling structure and internal equipment, extend the service life of the ceiling, and at the same time improve the sound insulation and heat insulation performance of the ceiling.

[0024] Furthermore, the mounting rail 3 is composed of a mounting portion 32 and a guide portion 33. The end of the mounting rail 3 is against the inner wall of the edge banding 21. The length of the mounting rail 3 is an integer multiple of the length of the sealing unit 1. The mounting rail 3 is equidistantly arranged along the length direction of the grille frame 2, so that the sealing unit 1 can be neatly installed on the mounting rail 3, ensuring the overall flatness and aesthetics of the ceiling. The distance between adjacent guide portions 33 matches the width of the sealing unit 1, which provides precise positioning for the installation of the sealing unit 1, so that the sealing unit 1 can smoothly cooperate with the mounting rail 3. A slide groove 31 is provided in the guide portion 33 of the mounting rails 3 on both sides, and two slide grooves 31 are symmetrically provided in the guide portions 33 of the remaining mounting rails 3.

[0025] It should be noted that the mounting rails 3 on both sides are formed by symmetrically cutting the remaining mounting rails 3 along the center line in the width direction. The mounting rails 3 on both sides are consistent with the remaining mounting rails 3 in length and height. The width of the mounting rails 3 on both sides is half the width of the remaining mounting rails 3, which ensures the consistency and versatility of the structure, and can be adjusted according to the special needs of the ceiling edge, thereby improving the utilization rate of materials. The side walls of the guide parts 33 of the mounting rails 3 on both sides are against the side walls of the edge sealing 21, and the parts of the base plate 11 extending out of the left and right sides of the sealing unit 1 match the width of the guide parts 33 of the mounting rails 3 on both sides, further enhancing the sealing and stability of the ceiling edge.

[0026] Furthermore, the positioning assembly includes a positioning unit 5, a spring 274 and a connecting plate 7. The positioning unit 5 is fixedly mounted on the base plate 11, providing a stable mounting base for the entire positioning assembly, ensuring that its position on the sealing plate unit 1 is fixed, so that the positioning function can be accurately realized when cooperating with the mounting guide rail 3. A positioning cavity 50 is provided inside the positioning unit 5, and the lower end of the positioning cavity 50 extends to the inside of the base plate 11. A baffle 52 is installed inside the positioning cavity 50, and a liquid guide hole 521 is provided in the middle of the baffle 52. The positioning cavity 50 is divided into an upper and a lower part by the baffle 52. A magnetic plate 501 is fixedly mounted in the middle of the upper positioning cavity 50. Two positioning blocks 51 are slidably engaged in the upper positioning cavity 50, and a liquid guide hole 521 is provided in the middle of the baffle 52. The positioning cavity 50 is divided into an upper and a lower part by the baffle 52. A sealing slide 71 is slidably connected to the positioning cavity 50 of the part, and limiting blocks 72 are connected to the top sides of the sealing slide 71. A limiting groove 73 matching the limiting blocks 72 is provided inside the base plate 11. The top of the sealing slide 71 and the baffle 52 are elastically connected by a spring 2 74. The connecting plate 7 is fixedly connected to the bottoms of multiple sealing slides 71 on the same side. Hydraulic oil is filled between the top of the sealing slide 71 and the positioning cavity 50. A card slot matching the connecting plate 7 is provided at the bottom of the sealing plate unit 1. By pulling the connecting plate 7, the movement of multiple sealing slides 71 can be controlled at the same time, and then the actions of the positioning blocks 51 in multiple positioning units 5 can be uniformly controlled, making the installation and disassembly operations of the sealing plate unit 1 on the mounting guide rail 3 more convenient and efficient.

[0027] The outer side of the positioning block 51 is rotatably connected with a ball 1 511. When the sealing plate unit 1 slides on the mounting guide rail 3, the ball 1 511 reduces the friction between the positioning block 51 and the slide groove 31, making the sliding process smoother. At the same time, it can also reduce the wear of the positioning block 51 and the slide groove 31, and extend their service life. The upper half of the positioning block 51 opposite to the magnetic plate 501 is magnetically set. The upper half of the positioning block 51 and the opposite surface of the magnetic plate 501 have opposite magnetic properties. The mutual attraction between the magnets is used to ensure that the positioning block 51 can be stably in a position relatively close to the magnetic plate 501 when not disturbed by other external forces. The top of the limit block 72 is fixedly connected to the limit rod 721. The interior of the positioning unit 5 is provided with a channel matching the limit rod 721, and the lower part of the positioning block 51 is provided with a limit hole 513 matching the limit rod 721.

[0028] When the cam 514 is in the closed position, the locking cam 512 is in the closed position, and the locking cam 513 is in the closed position, and the cam 514 is in the closed position, and the cam 512 is in the closed position, and the cam 513 ... The bottom of the mounting portion 32 is abutted against each other. When external force is applied to the pull plate 75, the sealing slide 71 stretches the spring 2 74 and moves downward, changing the pressure distribution of the hydraulic oil, thereby controlling the action of the positioning block 51. In the initial state, the top end of the limit rod 721 is engaged with the inside of the limit hole 513, locking the positioning block 51 in a specific position. When the sealing slide 71 moves, the limit rod 721 disengages from the limit hole 513, allowing the positioning block 51 to move under the action of the magnetic force of the magnetic plate 501 and the pressure of the hydraulic oil, thereby realizing the separation or engagement of the positioning block 51 with the slide groove 31.

[0029] Furthermore, a guide groove 512 is provided in the middle of the side wall of the positioning block 51 facing the liquid guide hole 521. When the limit block 72 is against the bottom of the limit groove 73, the positioning block 51 is in contact with the side wall of the magnetic plate 501. At this time, the interval enclosed by the guide grooves 512 on the two positioning blocks 51 and the magnetic plate 501 is opposite to the liquid guide hole 521, and the width of the magnetic plate 501 is sufficient to form a closed interval with the two guide grooves 512. At this time, the hydraulic oil in the lower positioning cavity 50 can flow between the upper and lower parts of the positioning cavity 50 through the liquid guide hole 521 and the guide groove 512, thereby controlling the movement of the positioning block 51, realizing the disengagement or engagement of the positioning block 51 with the slide groove 31, and completing the installation or disassembly of the sealing plate unit 1.

[0030] Furthermore, the positioning block 51 is sealed to the upper positioning cavity 50, and the sealing slide 71 is sealed to the lower positioning cavity 50. There are multiple positioning units 5 equidistantly arranged and symmetrically distributed along the central axis of the corresponding sealing unit 1, ensuring that the sealing unit 1 is evenly stressed on the mounting guide rail 3, and is more stable during sliding and positioning, avoiding installation deviation or shaking caused by uneven force, and improving the installation accuracy and stability of the entire prefabricated ceiling. In the initial state, the bottom of the connecting plate 7 is flush with the bottom wall of the base plate 11, and a mounting groove 70 is provided at the bottom of the connecting plate 7. A pull plate 75 is rotatably connected to the inside of the mounting groove 70. The length of the pull plate 75 is less than the length of the mounting groove 70, which is convenient for the operator to grab the pull plate 75 to apply external force to the connecting plate 7 to achieve control of the positioning component. At the same time, the pull plate 75 can be rotatably stored in the mounting groove 70, and will not affect the normal installation of the sealing unit 1 and the overall aesthetics of the ceiling when not in use.

[0031] In this embodiment, first, the grid frame 2 is connected and fixed to the ceiling with the hanger 4 through the connecting piece 41. The hanger 4 takes the task of transferring the weight of the entire ceiling to the building structure. The multiple grid spaces on the grid frame 2 provide a basic framework for the installation of the sealing unit 1. The edge sealing 21 is installed around the lower side of the grid frame 2. The edge sealing 21 not only beautifies the appearance of the ceiling, but also protects the sealing unit 1 and the mounting guide rail 3 to prevent them from collision and damage.

[0032] When the sealing plate unit 1 needs to be installed, the operator pulls the pull plate 75, which drives the connecting plate 7 to move downward. Since the connecting plate 7 is fixedly connected to the bottom of multiple sealing slide plugs 71 on the same side, the sealing slide plug 71 moves downward accordingly, stretching the spring 2 74. The movement of the sealing slide plug 71 changes the pressure distribution of the hydraulic oil in the lower positioning cavity 50. As the sealing slide plug 71 moves downward, the limit block 72 drives the limit rod 721 to move downward, and the limit rod 721 disengages from the limit hole 513 at the bottom of the positioning block 51. At this time, under the combined action of the change in hydraulic oil pressure and the magnetic force of the magnetic plate 501, the positioning block 51 begins to move toward the magnetic plate 501 (refer to Figure 11-13 ), at this time, the operator can hold the connecting plate 7 and the sealing slide plug 71 on one side with both hands respectively, and then the sealing plate unit 1 can be lifted to align it with the corresponding mounting guide rail 3. After alignment, the two hands are gradually withdrawn while holding the bottom of the sealing plate unit 1. At this time, under the elastic force of the spring 2 74, the connecting plate 7 is gradually reset and the hydraulic oil is squeezed into the upper positioning cavity 50. Under the push of the hydraulic oil, the magnetic force between the magnetic plate 501 and the corresponding positioning block 51 is overcome, so that the two positioning blocks 51 are moved away from each other to achieve the engagement with the slide groove 31. At the same time, the limit rod 721 is also engaged with the limit hole 513 at the bottom of the corresponding positioning block 51 (refer to Figure 7), lock the positioning block 51 at the current position, thus completing the installation and positioning of the single sealing plate unit 1.

[0033] The length of the installation guide rail 3 is an integer multiple of the length of the closing panel unit 1 and is arranged at equal intervals. The spacing between adjacent guide parts 33 matches the width of the closing panel unit 1, providing a precise positioning basis for the installation of the closing panel unit 1. The positioning block 51 in the positioning assembly is precisely matched with the slide groove 31 to ensure that the installation position of the closing panel unit 1 is accurate, greatly improving the overall flatness and aesthetics of the ceiling, and ensuring that each closing panel is tightly fitted after installation, reaching extremely high decoration standards.

[0034] In particular, the guide groove 512 opened in the middle of the side wall of the positioning block 51 also plays a key role in the installation process. When the limit block 72 abuts against the bottom of the limit groove 73, the area enclosed by the guide grooves 512 on the two positioning blocks 51 and the magnetic plate 501 is directly opposite to the liquid guide hole 521, and the width of the magnetic plate 501 is sufficient to form a closed area with the two guide grooves 512 (refer to Figure 12-13 ), at this time, the hydraulic oil in the lower positioning cavity 50 can flow between the upper and lower parts of the positioning cavity 50 through the liquid guide hole 521 and the guide groove 512, ensuring that the oil flow can effectively promote the movement of the positioning block 51, so that the positioning block 51 can be accurately separated or engaged with the slide groove 31, thereby successfully completing the installation or disassembly of the sealing unit 1.

[0035] After the installation of the closing panel unit 1 is completed, the operator can push the closing panel unit 1 to move along the slide groove 31 so that its side wall is against the sealing edge 21, and then repeat the above steps to install other closing panel units 1 in turn, and finally complete the assembly of the entire ceiling; when a closing panel unit 1 is damaged or needs maintenance, just simply pull the pull plate 75 to disengage the positioning block 51 from the slide groove 31, and the closing panel unit 1 can be quickly removed from the mounting guide rail 3.

[0036] The present application adopts a unique positioning component and a sliding cooperation design of the installation guide rail 3. By pulling the pull plate 75, the separation or engagement of the positioning block 51 and the slide groove 31 can be easily controlled, thereby realizing the convenient installation and disassembly of the sealing plate unit 1. It can be operated by one person without the help of additional tools and the cooperation of multiple people, which greatly reduces the installation difficulty and the demanding requirements for installation accuracy. For example, in home decoration, even non-professionals can complete the installation and replacement of the sealing plate unit 1 in a short time. The operation is extremely simple. Compared with the traditional ceiling installation, this design abandons the tedious on-site assembly steps, significantly improves the construction efficiency, and reduces the labor cost investment; the positioning block 51 The ball bearing 511 that is rotated and engaged on the outside greatly reduces the friction between the ball bearing 51 and the slide groove 31, which makes the closing plate unit 1 slide more smoothly on the installation guide rail 3, and the operator pushes the closing plate unit 1 more easily, further speeding up the installation speed and improving the convenience of assembly operation; since the closing plate unit 1 adopts modular installation, when a problem occurs in a certain closing plate unit 1, it is only necessary to pull the pull plate 75 to disengage the positioning block 51 from the slide groove 31, and the closing plate unit 1 can be easily removed from the installation guide rail 3 for maintenance or replacement. The operation is simple and convenient, which reduces maintenance costs and time and improves the convenience of later maintenance of the ceiling.

[0037] Example 2, refer to Figure 7-Figure 15 The sealing unit includes an air storage box 6, a spring 63, an annular air bag 8 and a plurality of air guide channels 9 opened in the substrate 11. The annular air bag 8 is fixed in the substrate 11 and arranged around the substrate 11. The air storage box 6 is fixedly arranged on the substrate 11 and distributed between adjacent positioning units 5. The internal sealing sliding connection of the air storage box 6 is provided with a pressure plate 62. The bottom of the pressure plate 62 and the bottom wall of the inner cavity of the air storage box 6 are elastically connected by a spring 63. The air storage box 6 located at the bottom of the pressure plate 62 is pre-filled with inert gas (such as nitrogen, argon, etc., with high stability). The bottom of the inner cavity of the air storage box 6 and the inner cavity of the annular air bag 8 are connected through the air guide channel 9. When the pressure plate 62 compresses the gas in the air storage box 6, the gas can smoothly enter the annular air bag 8 through the air guide channel 9 to realize the transfer of gas, thereby completing the inflation process of the annular air bag 8. Several pressure rods 61 are fixedly connected to the top of the pressure plate 62, and a notch matching the pressure rod 61 is provided on the top of the air storage box 6.

[0038] It should be noted that the top of the gas storage box 6 is rotatably connected with the second ball 611. On the one hand, when the sealing plate unit 1 slides on the installation guide rail 3, the second ball 611 can reduce the friction between the gas storage box 6 and the slide groove 31, making the installation process smoother. On the other hand, the second ball 611 can accurately transfer the pressure on the top of the slide groove 31 to the pressure rod 61 and the pressure plate 62, ensuring the smooth progress of the gas compression and transmission process. The width and height of the gas storage box 6 are equal to the width and height of the positioning unit 5, ensuring that the sealing plate unit 1 can be installed smoothly. It can also enhance the overall structural strength. When the spring 1 63 is in the initial state, the annular airbag 8 is in an unsaturated state. When the top of the ball 2 611 is against the top of the slide groove 31, the annular airbag 8 is in a saturated state. When the gas in the air storage box 6 enters the annular airbag 8 through the air guide channel 9, the annular airbag 8 gradually expands until it reaches a saturated state. At this time, the annular airbag 8 can fill the gap between the substrate 11 and the surrounding components, play a good sealing role, prevent dust, moisture, etc. from entering the interior of the ceiling, and improve the sealing and overall performance of the ceiling.

[0039] In this embodiment, when the sealing unit 1 is not installed, the annular airbag 8 is in an unsaturated state. When the sealing unit 1 is installed on the mounting guide rail 3, the top of the ball 2 611 is against the top of the slide groove 31. As the sealing unit 1 is further installed in place, the ball 2 611 is subjected to the pressure of the top of the slide groove 31, and the pressure is transmitted to the pressure plate 62 through the pressure rod 61, so that the pressure plate 62 overcomes the elastic force of the spring 1 63 and slides downward. When the pressure plate 62 slides downward, it compresses the inert gas pre-filled in the gas storage box 6, so that the gas enters the annular airbag through the gas guide channel 9. Bag 8. When the gas in the air storage box 6 enters the annular airbag 8 through the air guide channel 9, the annular airbag 8 gradually expands until it reaches a saturated state. At this time, the annular airbag 8 can tightly fill the gap between the substrate 11 and the surrounding components, forming an effective sealing barrier to prevent dust, moisture, etc. from entering the interior of the suspended ceiling. This sealing method that uses changes in gas pressure has better adaptability and sealing than traditional sealing methods (such as using sealing strips, etc.), and can better cope with the slight displacement and deformation that may occur in the suspended ceiling during use.

[0040] When the closing plate unit 1 is installed, the annular airbag 8 is always in a saturated state. In the process of pushing the closing plate unit 1 to move along the slide groove 31, the annular airbag 8 can play a role in buffering and noise reduction. This is because the annular airbag 8 in the saturated state has a certain elasticity. When the closing plate unit 1 is pushed to move by external force, the annular airbag 8 can absorb and disperse part of the external force, reduce the rigid collision between the closing plate unit 1 and the surrounding components, thereby playing a buffering role. At the same time, this elastic buffering effect can also reduce the noise caused by the collision and improve the comfort of the suspended ceiling during use. When the suspended ceiling is subjected to external vibrations or impacts of objects, such as vibrations caused by decoration upstairs, the sealing strips or sealants cannot absorb the vibration energy, which will cause the suspended ceiling to produce loud noises and affect the comfort of the indoor environment. The present application uses the annular airbag 8 to have elasticity in a saturated state. When the closing plate unit 1 moves or is subjected to external vibrations, it can absorb and disperse external forces, reduce rigid collisions, reduce noise, and improve the user experience.

[0041] In addition, when it is necessary to remove the sealing unit 1, it is only necessary to pull the corresponding pull plate 75. At this time, the corresponding positioning block 51 shrinks accordingly. This shrinkage causes the positioning block 51 to be disengaged from the sliding groove 31 in the guide portion 33 of the mounting guide rail 3. Compared with traditional ceiling fixing methods, such as bolt fastening, there is no need to use tools for tedious disassembly operations, which greatly improves the convenience of disassembly. At the same time, under the action of spring 1 63, a downward thrust is also applied to the sealing unit 1, which helps to overcome the friction and other small resistances that may exist between the sealing unit 1 and the mounting guide rail 3, making it easier for the sealing unit 1 to be detached from the mounting guide rail 3. At the same time, under the action of the pressure difference, the gas in the annular airbag 8 is extracted and returned to the gas storage box 6. After the gas in the annular airbag 8 is extracted, the airbag shrinks and no longer fills the gap between the substrate 11 and the surrounding components. On the one hand, this eliminates the obstruction caused by the annular airbag 8 to the disassembly of the sealing unit 1 in the sealed state. On the other hand, the spatial constraint of the sealing unit 1 in the vertical direction is also reduced accordingly, making it easier for the sealing unit 1 to be detached from the mounting guide rail 3.

[0042] The present application utilizes the change of gas pressure to expand the annular airbag 8 to fill the gap. Compared with traditional sealing strips and other methods, it has better adaptability to the tiny displacements and deformations that may occur during the use of the suspended ceiling, and can effectively prevent dust and moisture from entering the interior of the suspended ceiling, protecting the suspended ceiling structure and equipment; when the sealing unit 1 is installed, the annular airbag 8 is in a saturated state and has elasticity. When the sealing unit 1 moves along the slide groove 31, it can absorb and disperse external forces, reduce rigid collisions, play a buffering role and reduce noise, and improve the comfort of using the suspended ceiling; pulling the pull plate 75 can shrink the positioning block 51 and disengage it from the slide groove 31 without the need for tools, which greatly improves the convenience of disassembly compared with traditional bolt fastening methods; the spring applies a downward thrust to overcome the friction and resistance between the sealing unit 1 and the guide rail, and helps the sealing unit 1 to disengage; at the same time, the gas in the annular airbag 8 is extracted and the airbag shrinks, eliminating sealing obstacles, reducing vertical space constraints, and further facilitating the disassembly of the sealing unit 1.
