Detailed implementation manners

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 6 , a closing structure that can be vertically limited and rotated according to an embodiment of the present invention includes an inspection opening provided between the wall surface 1 and the decorative panel 2, a closing plate 3 for closing the inspection opening, a rotating member provided on the wall surface 1 and rotatably connected to one end of the closing plate 3, and a plug provided at the other end of the closing plate 3 for connecting the other end of the closing plate 3 to the decorative panel 2; the closing plate 3 can move horizontally on the rotating member, and the rotating member is provided with a notch 42 for connecting or disengaging one end of the closing plate 3 from the rotating member. When the closing plate 3 moves horizontally on the rotating member towards the decorative panel 2, the plug connects the closing plate 3 to the decorative panel 2. When the closing plate 3 moves away from the decorative panel 2 on the rotating member, the plug is disengaged from the decorative panel 2.

[0033] When installing the ceiling, in order to facilitate later maintenance, an inspection opening is reserved between the decorative panel 2 of the ceiling and the wall 1. However, in order to ensure the integrity and aesthetics of the ceiling, it is necessary to close the inspection opening with a closing plate 3 to ensure the integrity of the ceiling appearance. A rotating member is provided on the wall 1. One end of the closing plate 3 is rotatably connected to the rotating member, and the closing plate 3 can move horizontally on the rotating member. A notch 42 is provided on the rotating member. One end of the closing plate 3 can be connected to or disengaged from the rotating member through the notch 42. When one end of the closing plate 3 is connected to the rotating member, the rotating member supports one end of the closing plate. A plug is provided at the other end of the closing plate 3 to connect the other end of the closing plate 3 to the decorative panel 2, thereby realizing the installation of the closing plate 3 between the ceiling and the wall 1 and completing the closing of the inspection opening by the closing plate 3.

[0034] Taking the inspection opening between the ceiling and the wall 1 being set at the leftmost side of the ceiling as an example, when performing maintenance on the ceiling and needing to open the inspection opening, first move the closing plate 3 horizontally on the rotating member in a direction away from the decorative panel 2 so that the plug is disengaged from the decorative panel 2, thereby disconnecting the right end of the closing plate 3 from the decorative panel 2; then, with the left end of the closing plate 3 rotatably connected to the rotating member as the center, rotate the closing plate 3 counterclockwise so that the right end of the closing plate 3 is lifted, and the lifted height is greater than the height of the decorative panel 2, thereby causing the closing plate 3 to be misaligned with the decorative panel 2; then move the closing plate 3 horizontally on the rotating member in a direction closer to the decorative panel 2. Since the closing plate 3 is misaligned with the decorative panel 2 at this time, the decorative panel 2 will not obstruct the horizontal movement of the closing plate 3. Therefore, the closing plate 3 can be horizontally moved on the rotating member to the position where the notch 42 is located; finally, move the other end of the closing plate 3 out of the rotating member from the notch 42, thereby realizing the disassembly of the closing plate 3 on the inspection opening and facilitating the maintenance worker to perform maintenance on the ceiling through the inspection opening.

[0035] After the maintenance is completed, it is necessary to reinstall the closing plate 3 on the inspection opening to ensure the integrity and aesthetics of the ceiling. The steps for installing the closing plate 3 on the inspection opening are opposite to the disassembly steps. First, tilt the closing plate 3 into the inspection opening so that the right end of the closing plate 3 is above the decorative panel 2 and the left end of the decorative panel 2 is above the rotating member; then move the closing plate 3 into the rotating member from the notch 42, keep the closing plate 3 in an inclined state, that is, in a misaligned state with the decorative panel 2, and move it on the rotating member in a direction away from the decorative panel 2 until the closing plate 3 and the plug do not overlap with the decorative panel 2; then, with the left end of the closing plate 3 rotatably connected to the rotating member as the center, rotate the closing plate 3 clockwise so that the right end of the closing plate 3 is flush with the decorative panel 2; finally, move the closing plate 3 horizontally on the rotating member in a direction closer to the decorative panel 2 until the plug is engaged with the decorative panel 2, thereby fixedly connecting the closing plate 3 to the decorative panel 2 and completing the installation of the closing plate 3 on the inspection opening.

[0036] In this embodiment, the rotating member includes a rotating base 4 provided on the wall surface 1 and a rotating shaft 31 provided at one end of the closing plate 3. A strip-shaped through hole 41 is horizontally provided on the rotating base 4 for the rotating shaft 31 to penetrate through. The rotating member includes the rotating base 4 and the rotating shaft 31. The rotating base 4 is fixed on the wall surface 1, and the rotating shaft 31 is provided at the end of the closing plate 3. A horizontal strip-shaped through hole 41 is provided on the rotating base 4, and the rotating shaft 31 at one end of the closing plate 3 penetrates through the strip-shaped through hole 41, so that the closing plate 3 can not only rotate around the rotating shaft 31 in the strip-shaped through hole 41, but also horizontally move along the horizontally provided strip-shaped through hole 41, realizing the installation and disassembly of the closing plate 3 on the inspection opening.

[0037] In this embodiment, a notch 42 is provided at the top of the rotating base 4 and communicates the strip-shaped through hole 41 with the outside. The rotating shaft 31 can enter and exit the strip-shaped through hole 41 from the notch 42. The notch 42 is provided at the top of the rotating base 4 away from the end connected to the wall surface 1, and the notch 42 communicates the strip-shaped through hole 41 with the outside, enabling the rotating shaft 31 to enter and exit the strip-shaped through hole 41 through the notch 42, realizing the connection or detachment between the closing plate 3 and the rotating base 4.

[0038] The notch 42 is provided at the end of the rotating base 4 away from the connection with the wall surface 1, that is, the end close to the decorative panel 2, so that when the closing plate 3 horizontally moves away from the decorative panel 2 in the rotating member, the rotating shaft 31 horizontally moves away from the notch 42 in the strip-shaped through hole 41. At this time, the rotating shaft 31 cannot move out of the strip-shaped through hole 41 from the notch 42, that is, the closing plate 3 cannot be detached from the rotating base 4, so that the rotating base 4 supports one end of the closing plate 3. Only when the closing plate 3 horizontally moves towards the decorative panel 2 in the rotating member, the rotating shaft 31 horizontally moves towards the notch 42 in the strip-shaped through hole 41 until the rotating shaft 31 is located below the notch 42, can the rotating shaft 31 be moved out of the rotating base 4 from the notch 42 when the closing plate 3 is moved upward, thus realizing the detachment between the closing plate 3 and the rotating base 4.

[0039] In this embodiment, a first insertion slot 34 is provided at the other end of the closing plate 3, and a second insertion slot 22 is provided at the end of the decorative panel 2 close to the closing plate 3. The plug-in member is a caulking strip 5 with one end inserted into the first insertion slot 34 and the other end inserted into the second insertion slot 22. A first insertion slot 34 is provided at the end of the closing plate 3 close to the decorative panel 2, and a second insertion slot 22 is provided at the end of the decorative panel 2 close to the closing plate 3. The plug-in member is the caulking strip 5. When one end of the caulking strip 5 is inserted into the first insertion slot 34 and the other end is inserted into the second insertion slot 22, the plug-in member fixedly connects the end of the closing plate 3 to the decorative panel 2; when one end of the caulking strip 5 is pulled out from the first insertion slot 34 or the second insertion slot 22, or both ends of the caulking strip 5 are simultaneously pulled out from the first insertion slot 34 and the second insertion slot 22, the closing plate 3 is detached from the decorative panel 2.

[0040] In this application, when installing the closing plate 3 on the inspection opening, the closing plate 3 is first inclined and inserted into the inspection opening, then the rotating shaft 31 at one end of the closing plate 3 is moved into the strip-shaped through hole 41 from the notch 42, and then the closing plate 3 is moved along the strip-shaped through hole 41 in a direction away from the decorative panel 2 until the closing plate 3 is horizontal and does not overlap with the range of the decorative panel 2, and the distance between the closing plate 3 and the decorative panel 2 is greater than the width of the caulking strip 5, so that one end of the caulking strip 5 can be inserted into the first insertion groove 34 at one end of the closing plate 3 without being blocked by the decorative panel 2. Finally, the closing plate 3 is moved along the strip-shaped through hole 41 in a direction close to the decorative panel 2 until the other end of the caulking strip 5 is inserted into the second insertion groove 22 on the decorative panel 2, realizing the fixed connection between the closing plate 3 and the decorative panel 2, and thus realizing the installation of the closing plate 3.

[0041] When disassembling the closing plate 3 from the inspection opening, first move the closing plate 3 in a direction away from the decorative panel 2 to pull out one end of the caulking strip 5 from the second insertion groove 22, thus realizing the separation of the closing plate 3 from the decorative panel 2; then pull out the other end of the caulking strip 5 from the first insertion groove 34 to realize the disassembly of the caulking strip 5 on the closing plate 3; then lift the right side of the closing opening to make the closing plate 3 rotate counterclockwise with the rotating shaft 31 as the center, so that the closing plate 3 is misaligned with the decorative panel 2, so that the rotating shaft 31 of the closing plate 3 can move in the strip-shaped through hole 41 in the direction of the decorative panel 2 until the rotating shaft 31 is located below the notch 42 without being blocked by the decorative panel 2, and finally move the closing plate 3 upward to move the rotating shaft 31 out of the strip-shaped through hole 41 from the notch 42, realizing the separation of the closing plate 3 from the rotating part, and thus realizing the disassembly of the closing plate 3.

[0042] It should be noted that when the closing plate 3 moves in a direction away from the decorative panel 2, one end of the caulking strip 5 needs to be pulled out from the second insertion groove 22, while the other end of the caulking strip 5 is still inserted into the first insertion groove 34. Therefore, in this application, it is necessary to make the limiting effect of the first insertion groove 34 on the caulking strip 5 stronger than the limiting effect of the second limiting groove on the caulking strip 5. The specific implementation method can be: the two ends of the caulking strip 5 have the same thickness, the thickness of the first insertion groove 34 is slightly less than the thickness of the second insertion groove 22, or the thicknesses of the first insertion groove 34 and the second insertion groove 22 are equal, and the thickness of the end of the caulking strip 5 inserted into the first insertion groove 34 is slightly greater than the thickness of the end inserted into the second insertion groove 22. The specific implementation method can be determined according to the actual use situation.

[0043] In this embodiment, it further includes a lapping member 6 for lapping the other end of the closing plate 3 on the installation keel 21 of the decorative panel 2. In this application, a lapping member 6 is also provided to lap one end of the closing plate 3 close to the decorative panel 2 on the decorative panel 2, thereby further strengthening the connection strength between the closing plate 3 and the decorative panel 2 and enhancing the stability of this closing structure. When installing a suspended ceiling on the wall top, it is usually to connect one end of a channel-shaped keel to the wall top and the other end to the decorative panel 2, and install the decorative panel 2 on the wall top to obtain the installation height of the suspended ceiling. In this application, the lapping member 6 laps one end of the closing plate 3 close to the decorative panel 2 on the installation keel 21 of the decorative panel 2. After the caulking strip 5 fixedly connects the end of the closing plate 3 to the decorative panel 2, the top of the closing plate 3 is lapped on the installation keel 21 at the top of the decorative panel 2, further strengthening the connection strength between the closing plate 3 and the decorative panel 2.

[0044] The reason for using the lapping method to lap the top of the closing plate 3 on the installation keel 21 at the top of the decorative panel 2 to strengthen the connection strength between the closing plate 3 and the decorative panel 2 is to facilitate the disassembly of the closing plate 3 at the inspection opening. Since in this application, when the closing plate 3 is disassembled at the inspection opening, it is necessary to lift one end of the closing plate 3 close to the decorative panel 2 upward to cause a dislocation between the closing plate 3 and the decorative panel 2, and it is also necessary to move the closing plate 3 upward to move the rotating shaft 31 out of the strip-shaped through hole 41 from the notch 42 to realize the separation of the closing plate 3 from the rotating member. The lapping method can not only strengthen the support of the decorative panel 2 for the closing plate 3, but also not hinder the upward movement of the closing plate 3 on the decorative panel 2, thus facilitating the disassembly of the closing plate 3 at the inspection opening and further facilitating the inspection of the suspended ceiling.

[0045] In this embodiment, the lapping member 6 includes a lapping keel 61 provided on the top of the closing plate 3, and a hanging plate 62 with one end fixedly connected to the lapping keel 61 and the other end hooked on the installation keel 21 of the decorative panel 2. The lapping member 6 includes a lapping keel 61 and a hanging plate 62. The lapping keel 61 is arranged at the top of one end of the closing plate 3 close to the decorative panel 2. One end of the hanging plate 62 is fixedly connected to the lapping keel 61, and the other end is hooked on the installation keel 21 of the decorative panel 2, so that the top of the closing plate 3 is lapped on the installation keel 21 at the top of the decorative panel 2, further strengthening the connection strength between the closing plate 3 and the decorative panel 2.

[0046] Since the closing plate 3 needs to be horizontally moved away from the decorative panel 2 when disassembled at the inspection opening, in order to prevent the hanging plate 62 lapped on the installation keel 21 of the decorative panel 2 from hindering the horizontal movement of the closing plate 3 away from the decorative panel 2, in this application, there should be enough distance between the limiting part extending downward of the hanging plate 62 and the side surface of the installation keel 21, so that the closing plate 3 can be horizontally moved on the rotating member until one end of the caulking strip 5 inserted into the second insertion groove 22 is completely withdrawn from the second insertion groove 22.

[0047] In this embodiment, the sum of the height of the overlapping keel 61 and the thickness of the hanging plate 62 is equal to the height of the installation keel 21 of the decorative panel 2. During actual use, the closing plate 3 and the decorative panel 2 are of the same type of plate, that is to say, the materials and thicknesses of the closing plate 3 and the decorative panel 2 are equal. Therefore, when closing the inspection opening, only the remaining decorative panel 2 needs to be used, instead of separately preparing another type of panel, thereby reducing the cost of ceiling installation. Setting the sum of the height of the overlapping keel 61 and the thickness of the hanging plate 62 to be equal to the height of the installation keel 21 on the decorative panel 2 is to enable the closing plate 3 to be installed on the inspection opening. When the closing plate 3 and the decorative panel 2 are at the same horizontal height, the bottom of the hanging plate 62 just abuts against the top of the installation keel 21 of the decorative panel 2, so that the decorative panel 2 plays a supporting role for the closing plate 3, enhancing the stability of this closing structure.

[0048] In this embodiment, it further includes a fixing member 7 for fixedly connecting one end of the closing plate 3 to the wall surface 1. Because in the previous embodiment, when the closing plate 3 is installed on the inspection opening, one end of the closing plate 3 is fixed to the decorative panel 2 through the caulking strip 5, and the rotating shaft 31 at the other end is still in a movable state in the strip-shaped through hole 41. Although this can also fix the closing plate 3 between the wall surface 1 and the decorative panel 2, only by inserting one end of the caulking strip 5 into the second insertion groove 22 to fix the closing plate 3, it is easy to cause the caulking strip 5 at one end of the closing plate 3 to be pulled out of the second insertion groove 22 when being accidentally touched externally, so that one end of the closing plate 3 is separated from the decorative panel 2. And the other end of the closing plate 3 is rotatably connected to the rotating member. Under the action of the self-weight of the closing plate 3, the closing plate 3 will rotate downward with the rotating shaft 31 as the center, thus causing accidental injury to people.

[0049] Therefore, in this application, when installing the closing plate 3 on the inspection opening, move the closing plate 3 toward the direction close to the decorative panel 2. After one end of the caulking strip 5 is inserted into the second insertion groove 22, then fixedly connect the end of the closing plate 3 close to the wall surface 1 to the wall surface 1 through the fixing member 7, thereby strengthening the fixation of the closing plate 3 and preventing potential safety hazards of the closing plate 3 under accidental external touch. When disassembling the closing plate 3 on the inspection opening, first disassemble the fixing member 7 from the closing plate 3 and the wall surface 1 so that it no longer fixes the closing plate 3 to the wall surface 1, and then move the closing plate 3 away from the decorative panel 2 and perform subsequent operations.

[0050] In this embodiment, the fixing member 7 includes a trimming strip with one end abutting against the wall surface 1 and the other end abutting against the bottom of the closing plate 3, a first screw with one end passing through the trimming strip and being screwed to the wall surface 1, and a second screw with one end passing through the trimming strip and being screwed to the closing plate 3. The fixing member 7 includes a trimming strip, a first screw and a second screw. One end of the trimming strip abuts against the wall surface 1, and the other end abuts against the bottom of the closing plate 3. Then, one end of the first screw passes through the trimming strip and is screwed to the wall surface 1, and one end of the second screw passes through the trimming strip and is screwed to the closing plate 3, thereby realizing the fixing of the closing plate 3 on the wall surface 1.

[0051] The fixing member 7 is configured in this structure to facilitate the installation and removal of the closing plate 3 on the inspection opening, and thus facilitate the inspection of the suspended ceiling. When installing the closing plate 3 on the inspection opening, it is only necessary to make the two ends of the trimming strip respectively abut against the wall surface 1 and the bottom of the closing plate 3, and then respectively pass the first screw and the second screw through the trimming strip and screw them into the wall surface 1 and the closing plate 3, and the fixing connection between the closing plate 3 and the wall surface 1 can be completed; when removing the closing plate 3 from the inspection opening, it is only necessary to screw out the first screw and the second screw from the wall surface 1 and the closing plate 3 respectively, so that the closing plate 3 and the wall surface 1 are no longer fixedly connected, thereby making the installation and removal of the closing plate 3 on the inspection opening convenient and fast.

[0052] In this embodiment, the rotating member further includes a rotating plate 32 vertically provided at one end of the closing plate 3, and a fixing plate 33 for fixedly connecting the rotating plate 32 to the closing plate 3. A groove 43 for accommodating the rotating plate 32 is provided in the middle of the rotating base 4, and a rotating shaft 31 is provided on the top of the rotating plate 32. A rotating plate 32 is vertically provided at one end of the closing plate 3 close to the wall surface 1, the rotating shaft 31 is provided on the top of the rotating plate 32, the fixing plate 33 fixes the rotating plate 32 on the top of the closing plate 3, a groove 43 is provided in the middle of the rotating base 4, strip-shaped through holes 41 are provided on both side walls of the groove 43, the rotating plate 32 is accommodated in the groove 43, and the rotating shaft 31 on the top of the rotating plate 32 passes through the strip-shaped through holes 41 from both sides of the groove 43, so that the rotating plate 32 can rotate in the groove 43, and thus the rotating connection between the closing plate 3 and the rotating base 4 is realized.
