By installing the retractable extension plate on the ceiling frame, and with the ceiling frame installed on the elevator platform, when maintaining and repairing the control cabinet and main unit, pushing the extension plate into the ceiling frame allows the elevator platform to be in a semi-open state, enabling a person to pass through the elevator platform for convenient maintenance and repair of the control cabinet and main unit.

[0004] Based on the aforementioned patents, existing retractable ceiling maintenance structures generally lack reliable self-locking functions. During maintenance operations, operators need to fix the maintenance plate at a specific telescopic position to form a stable operating space. Some retractable ceilings lack effective guiding and limiting devices in their structural design, which leads to the extension plate easily shifting or swaying during the telescopic process. At the same time, retractable ceilings need to overcome significant friction during telescopic processes, requiring operators to exert considerable force to pull or push the extension plate. Therefore, this utility model provides a retractable ceiling that facilitates maintenance and repair. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a retractable ceiling that facilitates maintenance and repair. It solves the problem that existing movable ceiling repair structures generally lack reliable self-locking functions. During maintenance, operators need to fix the repair panel at a specific telescopic position to form a stable operating space. Some retractable ceilings lack effective guiding and limiting devices in their structural design, which leads to the extension panel easily shifting or swaying during telescopic operation. At the same time, retractable ceilings need to overcome significant friction during telescopic operation, requiring operators to exert considerable force to pull or push the extension panel.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a retractable ceiling that facilitates maintenance and repair, comprising a ceiling frame, wherein the ceiling frame is provided with a connecting mechanism for facilitating maintenance and repair of the ceiling, the connecting mechanism comprising: A sliding assembly includes a slide rail bracket fixed at both ends of a ceiling frame. The slide rail bracket has a slide groove inside, and a protrusion is slidably connected inside the slide groove. An extension plate is fixed to one side wall of the protrusion. A stop block is fixed at the edge of the slide groove, and the inner wall of the stop block is slidably connected to the protrusion. A limiting component for preventing the extension plate from falling off is provided on the upper end surface of the extension plate. A support plate is fixed to the inner wall of the slide rail bracket, and rollers are evenly distributed on the surface of the support plate. The locking assembly includes a fixing block fixed to the lower end face of a support plate, and a support shaft connected to the support block via a gear assembly is provided inside the fixing block. One end of the support shaft is provided with a self-locking assembly for locking.

[0007] Preferably, the limiting component includes a guide rod evenly fixed on the upper surface of the extension plate, the guide rod extending into the ceiling frame and having a limiting plate fixed at one end, the limiting plate being fitted and connected to one end of the ceiling frame.

[0008] Preferably, the roller shaft is rotatably connected to the surface of the support plate, and the lower end face of the extension plate slides in contact with the roller shaft.

[0009] Preferably, the gear assembly includes a slide rod slidably connected inside the fixed block, tooth blocks evenly distributed on the upper end face of the slide rod, a fixed plate fixed to the side wall of the fixed block, a support shaft passing through the interior of the fixed plate and rotatably connected to the fixed plate, and a transmission gear fixed to the outer wall of the center end of the support shaft, the transmission gear meshing with the tooth blocks.

[0010] Preferably, a pull block is fixed to one end of the slide rod, and a pull ring for pulling is fixed to one side wall of the pull block.

[0011] Preferably, the self-locking assembly includes a vertical plate fixed at the edge of one side wall of the fixed block, a locking gear fixed at one end of the support shaft extending to the vertical plate, slots evenly formed on the outer wall of the locking gear, an mounting block fixed at one end of the vertical plate, a spring provided on the inner wall of the mounting block, and a locking block connected to one end of the spring, one end of the locking block engaging with the slot, a movable shaft fixed on the vertical plate, the other end of the locking block rotatably connected to the movable shaft, a protective shell fixed on one side of the fixed block, the self-locking assembly located inside the protective shell, and a toggle lever fixed on one side wall of the locking block.

[0012] Beneficial effects This utility model provides a retractable ceiling that is easy to maintain and repair. Compared with the prior art, it has the following advantages: Firstly, the sliding groove and the sliding block of the slide rail bracket of this utility model have a sliding fit, combined with the lateral limiting of the protrusion by the stop block, to ensure that the extension plate can only make linear extension and retraction movements in the horizontal direction, avoiding deviation and shaking during movement, and improving the overall structural stability of the ceiling. The setting of the roller shaft reduces the friction force when the extension plate extends and retracts, allowing the operator to easily pull or push the extension plate, improving the convenience of operation. The cooperation between the guide rod and the limiting plate in the limiting component, as well as the cooperation between the protrusion and the stop block, form a double anti-fall-off protection, which can prevent the extension plate from falling off the ceiling frame even in the case of elevator vibration or operation error.

[0013] Secondly, when the support shaft of this utility model rotates, the locking gear fixed to one end of the vertical plate will rotate synchronously. At this time, the slot on the outer wall of the locking gear will push the locking block that is engaged with it to rotate around the movable shaft, while compressing the spring on the inner wall of the mounting block. The locking block temporarily disengages from the slot and does not lock the locking gear. The extension plate can extend and retract normally. When the operator stops pulling the extension plate, the slide bar stops sliding, the transmission gear and the support shaft stop rotating, and the locking gear also stops. At this time, the compressed spring releases its elastic potential energy, pushing the locking block to rotate in the opposite direction around the movable shaft, so that the locking block re-engages into the slot of the locking gear. The mechanical engagement between the locking block and the slot restricts the rotation of the locking gear. Thus, through the linkage of the support shaft, transmission gear, gear block, and slide bar, the position of the extension plate is fixed, achieving locking and preventing the extension plate from moving in case of accidents.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-6 This utility model provides a technical solution: a retractable suspended ceiling that is easy to maintain and repair, including a ceiling frame 1, on which a connecting mechanism for facilitating maintenance and repair of the ceiling is provided, the connecting mechanism including: The sliding assembly includes a slide rail bracket 201 fixed at both ends of the ceiling frame 1. The slide rail bracket 201 has a slide groove 202 inside. A protrusion 204 is slidably connected inside the slide groove 202. An extension plate 2 is fixed to one side wall of the protrusion 204. A stop block 203 is fixed at the edge of the slide groove 202, and the inner wall of the stop block 203 is slidably connected to the protrusion 204. A limiting component for preventing the extension plate 2 from falling off is provided on the upper end surface. A support plate 4 is fixed to the inner wall of the slide rail bracket 201. Rollers 401 are evenly distributed on the surface of the support plate 4. The locking assembly includes a fixing block 5 fixed to the lower end face of the support plate 4. The fixing block 5 has a support shaft 702 connected by a gear assembly inside. One end of the support shaft 702 is provided with a self-locking assembly for locking.

[0018] In a preferred embodiment, the limiting component includes a guide rod 3 uniformly fixed on the upper surface of the extension plate 2. The guide rod 3 extends into the ceiling frame 1 and a limiting plate 301 is fixed at one end. The limiting plate 301 is attached to one end of the ceiling frame 1. The roller shaft 401 is rotatably connected to the surface of the support plate 4, and the lower surface of the extension plate 2 is attached to and slides against the roller shaft 401. When the extension plate 2 needs to be extended for maintenance and repair, a pulling force or a pushing force is applied to the extension plate 2.

[0019] Furthermore, the extension plate 2 drives the protrusion 204 to slide within the groove 202 of the slide rail bracket 201, thereby realizing the extension and retraction movement of the extension plate 2. During the extension and retraction of the extension plate 2, the guide rod 3 slides within the ceiling frame 1, and the limiting plate 301 is always in contact with one end of the ceiling frame 1 to prevent the extension plate 2 from shifting or falling off in the direction perpendicular to the extension and retraction. At the same time, the lower end face of the extension plate 2 slides in contact with the roller 401 on the support plate 4. The rotation of the roller 401 reduces the friction force during the extension and retraction of the extension plate 2, making the extension and retraction process smoother. The stop block 203 restricts the sliding range of the protrusion 204 within the groove 202 to prevent the extension plate 2 from excessively extending and retracting and detaching from the slide rail bracket 201.

[0020] In a preferred embodiment, the gear assembly includes a slide rod 501 slidably connected inside the fixed block 5. Tooth blocks 7 are evenly distributed on the upper end face of the slide rod 501. A fixed plate 701 is fixed to the side wall of the fixed block 5. A support shaft 702 passes through the interior of the fixed plate 701 and is rotatably connected to the fixed plate 701. A transmission gear 703 is fixed to the outer wall of the center end of the support shaft 702, and the transmission gear 703 meshes with the tooth blocks 7. A pull block 502 is fixed to one end of the slide rod 501. A pull ring for pulling is fixed to one side wall. One end of the pull block 502 is fixedly connected to the extension plate 2. When the operator pulls the extension plate 2, the pull block 502 fixedly connected to the extension plate 2 will synchronously drive the slide rod 501 to slide along the inside of the fixed block 5. Since the upper end face of the slide rod 501 is evenly distributed with tooth blocks 7, and the tooth blocks 7 mesh with the transmission gear 703 fixed to the outer wall of the support shaft 702, the linear motion of the slide rod 501 is converted into the rotational motion of the support shaft 702 through the meshing of the tooth blocks 7 and the transmission gear 703.

[0021] In a preferred embodiment, the self-locking assembly includes a vertical plate 8 fixed to the edge of one side wall of the fixing block 5. A locking gear 801 is fixed to one end of the support shaft 702 extending to the vertical plate 8. The outer wall of the locking gear 801 is evenly provided with slots. A mounting block 802 is fixed to one end of the vertical plate 8. A spring 803 is provided on the inner wall of the mounting block 802, and one end of the spring 803 is connected to a locking block 804. One end of the locking block 804 engages with the slots. A movable shaft 805 is fixed on the vertical plate 8. The other end of the locking block 804 is rotatably connected to the movable shaft 805. A protective shell 6 is fixed to one side of the fixing block 5. The self-locking assembly is located inside the protective shell 6. A toggle lever 806 is fixed to one side wall of the locking block 804. When the support shaft 702 rotates, the locking gear 801 fixed to one end of the vertical plate 8 will rotate synchronously. At this time, the locking gear... The slot on the outer wall of 801 pushes the locking block 804, which is engaged with it, to rotate around the movable shaft 805. At the same time, it compresses the spring 803 on the inner wall of the mounting block 802. The locking block 804 temporarily disengages from the slot and does not lock the locking gear 801. The extension plate 2 can extend and retract normally. When the operator stops pulling the extension plate 2, the slide rod 501 stops sliding, the transmission gear 703 and the support shaft 702 stop rotating, and the locking gear 801 also stops. At this time, the compressed spring 803 releases its elastic potential energy, pushing the locking block 804 to rotate in the opposite direction around the movable shaft 805, so that the locking block 804 re-engages into the slot of the locking gear 801. The mechanical engagement between the locking block 804 and the slot restricts the rotation of the locking gear 801. Then, through the linkage of the support shaft 702, the transmission gear 703, the toothed block 7, and the slide rod 501, the position of the extension plate 2 is fixed, and locking is achieved.

[0022] When it is necessary to retract the extension plate 2, the operator can move the lever 806 in the self-locking assembly to drive the locking block 804 to rotate around the movable shaft 805 against the elastic force of the spring 803, so that the locking block 804 disengages from the slot of the locking gear 801 and releases the locking state. Then the extension plate 2 can be pushed again for retraction adjustment.

[0023] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0024] During operation, when the extension plate 2 needs to be telescopically extended for maintenance and repair, a pulling or pushing force is applied to the extension plate 2. The extension plate 2 drives the protrusion 204 to slide in the slide groove 202 of the slide rail bracket 201 to achieve telescopic movement. During this process, the guide rod 3 slides in the ceiling frame 1, and the limiting plate 301 is always in contact with one end of the ceiling frame 1 to prevent the extension plate 2 from shifting or falling off in the direction perpendicular to the telescopic direction. At the same time, the lower end face of the extension plate 2 slides in contact with the roller 401 on the support plate 4. The rotation of the roller 401 reduces the friction force when the extension plate 2 telescopically extends and retracts. The stop block 203 limits the sliding range of the protrusion 204 to prevent the extension plate 2 from excessively telescopically extending and retracting and falling off the slide rail bracket 201. Then, when the operator pulls the extension plate 2, the pull block 502, which is fixedly connected to the extension plate 2, synchronously drives the slide rod 501 to slide along the inside of the fixed block 5. Because the toothed blocks 7 evenly distributed on the upper end face of the slide rod 501 mesh with the transmission gear 703 fixed on the outer wall of the support shaft 702, the linear motion of the slide rod 501 is converted into the rotational motion of the support shaft 702 through the meshing of the toothed blocks 7 and the transmission gear 703. When the support shaft 702 rotates, the locking gear 801, which extends to one end of the vertical plate 8, rotates synchronously. The slot on the outer wall of the locking gear 801 pushes the locking block 804, which is engaged with it, to rotate around the movable shaft 805. At the same time, the spring 803 on the inner wall of the mounting block 802 is compressed. The locking block 804 temporarily disengages from the slot and does not lock the locking gear 801. The extension plate 2 can extend and retract normally. When the operator stops pulling the extension plate 2, the slide bar 501 stops sliding, the transmission gear 703 and the support shaft 702 stop rotating, and the locking gear 801 also stops. At this time, the compressed spring 803 releases its elastic potential energy, pushing the locking block 804 to rotate in the opposite direction around the movable shaft 805, so that the locking block 804 is re-engaged into the slot of the locking gear 801. The mechanical engagement between the locking block 804 and the slot restricts the rotation of the locking gear 801. Then, through the linkage of the support shaft 702, the transmission gear 703, the toothed block 7, and the slide bar 501, the position of the extension plate 2 is fixed, and locking is achieved.
