[0038] like Figure 1 , Figure 2 and Figure 3 As shown, a fireproof decorative panel for an elevator car is installed on the inner wall of the car 1, comprising: a panel 2, which can be partially embedded in a groove 27 opened in the inner wall of the car 1 so that the panel 2 and the groove 27 can form a mating surface that fits against each other; an insert plate 6, which slides in conjunction with a sliding groove 7 opened in the mating surface of the panel 2, and the panel 2 is provided with an inner cavity 5 for receiving the insert plate 6, the inner cavity 5 being connected to the sliding groove 7, and one end of the insert plate 6 being able to be inserted into an insertion hole 8 opened in the inner side of the groove 27 to prevent the panel 2 from moving relative to the inner wall of the car 1; a driving structure for driving the insert plate 6 to slide along the sliding groove 7 so that the insert plate 6 is inserted into and disengaged from the insertion hole 8; and a locking structure for locking the driving structure to prevent it from driving the insert plate 6 to move.
[0039] The above technical solution can improve the installation and disassembly efficiency of the plate 2. In use, the corresponding part of the plate 2 is fitted into the groove 27 on the inner wall of the car 1, ensuring that the insert plate 6 is aligned with the insertion hole 8 inside the car 1. The drive structure is operated to drive the insert plate 6 to slide out along the slide groove 7, so that the insert plate 6 is inserted into the insertion hole 8 inside the groove 27, thereby fixing the plate 2 to the surface of the car 1. Then, the locking structure is used to lock the drive structure, thereby completing the installation. Therefore, the quick installation can be achieved by the insertion and removal of the insert plate 6 and the insertion hole 8, which is highly efficient.
[0040] like Figure 2 and Figure 3 As shown, in this embodiment, the plate 2 is provided with a plurality of positioning protrusions 3 on the side near the car 1, and the positioning protrusions 3 engage with the positioning grooves 4 formed on the surface of the car 1.
[0041] The above technical solution can conveniently preposition the plate 2 on the surface of the car 1. When the positioning protrusion 3 of the plate 2 is inserted into the positioning groove 4 on the surface of the car 1, it can prevent the plate 2 from sliding along the surface of the car 1, so that the insertion plate 6 is aligned with the insertion hole 8.
[0042] like Figure 2 and Figure 3 As shown, in this embodiment, the drive structure includes: a gear 10; a rotating shaft 11, which is connected to the shaft of the gear 10, the rotating shaft 11 is rotatably disposed in the inner cavity 5, the gear 10 meshes with the rack 9 disposed on one side of the insert plate 6, and one end of the rotating shaft 11 passes through the plate body 2.
[0043] The above technical solution can drive the insert plate 6 to slide through gear transmission. In use, rotating the shaft 11 can drive the gear 10 to rotate, so that the gear 10 can drive the insert plate 6 to slide along the slide groove 7 through meshing with the rack 9.
[0044] like Figure 4 and Figure 5 As shown, in this embodiment, the drive structure includes: a bearing bracket 12, which is fixedly disposed in the inner cavity 5; and a ball bearing 13, which is disposed in the bearing mounting groove of the bearing bracket 12, and the ball bearing 13 is adapted to the rotating shaft 11.
[0045] The above technical solution can reduce the rotational resistance of the shaft 11 and reduce the wear of the shaft 11.
[0046] like Figure 4 and Figure 6 As shown, in this embodiment, the locking structure includes: a fixed plate 19, one end of which is fixedly connected to the end of the rotating shaft 11 that passes through the plate body 2; a movable plate 16; a plurality of limiting posts 17, which are disposed at the end of the movable plate 16 near the fixed plate 19, and the plurality of limiting posts 17 pass through the through holes 20 opened on the surface of the fixed plate 19; a baffle 18, which is disposed at the end of the limiting posts 17 that pass through the through holes 20; and a spring 21, which is disposed on the surface of the limiting posts 17 and between the baffle 18 and the fixed plate 19, and the spring 21 can apply a spring force along its axial direction to the limiting posts 17 so that the limiting posts 17 are inserted into the limiting holes 22 opened on the surface of the plate body 2;
[0047] The above technical solution can lock the rotating shaft 11 to prevent accidental rotation. In use, by pulling the handle 26 on the surface of the movable plate 16, the limiting post 17 can be disengaged from the limiting hole 22, thereby releasing the rotation restriction of the rotating shaft 11. When the rotating shaft 11 rotates to the required position and the limiting post 17 is aligned with the limiting hole 22, the handle 26 is released. The spring 21 can apply an axial force to the limiting post 17, and the limiting post 17 is inserted into the limiting hole 22, thus locking the rotating shaft 11.
[0048] like Figure 4As shown, in this embodiment, a recessed groove 15 is formed on the surface of the plate 2 to accommodate the movable plate 16 and the fixed plate 19.
[0049] The above technical solution allows the movable plate 16 and the fixed plate 19 to be easily stored inside the plate body 2, ensuring that there are no protruding parts on the surface of the plate body 2 that affect the tactile feel.
[0050] like Figure 4 and Figure 6 As shown, in this embodiment, the fixing plate 19 is provided with a threaded rod 23 on the side near the plate body 2. The threaded rod 23 is threadedly engaged with the internal threaded groove 14 opened at one end of the rotating shaft 11. The plate body 2 is also provided with an outer sleeve 24 surrounding the threaded rod 23 on the side near the plate body 2. One end of the outer sleeve 24 is in contact with the plate body 2.
[0051] like Figure 5 As shown, in this embodiment, the rear end of the plate 2 is detachably provided with a rear cover 25 for sealing the inner cavity 5, and the bearing bracket 12 includes two brackets that are movably hinged at one end and fixed between the brackets with bolts.
[0052] The above technical solution allows for easy disassembly and installation of the fixing plate 19 and the rotating shaft 11. At the same time, the outer sleeve 24 can prevent the rotating shaft 11 from sliding axially. When it is necessary to disassemble the rotating shaft 11, first remove the back cover 25, fix the gear 10 with one hand, and rotate the fixing plate 19 with the other hand to make it drive the threaded rod 23 to disengage from the internal thread groove 14 of the rotating shaft 11. Then the rotating shaft 11 can be pulled out from the ball bearing 13.
[0053] like Figure 3 and Figure 4 As shown, in this embodiment, the cross-section of the insert plate 6 is an I-shaped structure, and correspondingly, the slide groove 7 is an I-shaped groove;
[0054] The above technical solution can improve the sliding stability of the insertion plate 6 and ensure that it can be accurately inserted into the insertion hole 8.
[0055] Working principle: In use, the corresponding part of the plate 2 is fitted into the groove 27 on the inner wall of the car 1. After the positioning protrusion 3 is inserted into the positioning groove 4, it can prevent the plate 2 from sliding along the surface of the car 1, so that the insert plate 6 is aligned with the insertion hole 8. By pulling the handle 26 set on the surface of the movable plate 16, the limiting post 17 can be driven to disengage from the limiting hole 22, thereby releasing the rotation restriction of the rotating shaft 11. By rotating the rotating shaft 11, the gear 10 can be driven to rotate, so that the gear 10, through meshing with the rack 9, drives the insert plate 6 to slide along the slide groove 7, so that the insert plate 6 is inserted into the insertion hole 8 inside the groove 27, thereby fixing the plate 2 to the surface of the car 1. When the handle 26 is released, the spring 21 can apply an axial elastic force to the limiting post 17, and the limiting post 17 is inserted into the limiting hole 22, completing the locking of the rotating shaft 11 and preventing accidental contact that would cause the rotating shaft 11 to rotate. Therefore, by inserting and removing the insert plate 6 and the insertion hole 8, quick installation can be achieved with high efficiency.
