[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 are within the scope of protection of the present invention.

[0024] Example 1:

[0025] Please refer to Figures 1-5. An elevator ceiling that is convenient for replacing the top core includes a ceiling frame 1. The bottom of the ceiling frame 1 is provided with mounting holes 5 around it. A plurality of mounting holes 5 are internally rotatably connected to a rotating shaft 6. The top of the rotating shaft 6 is fixedly connected to a limit head 7. The number of the limit heads 7 is several. The limit heads 7 are respectively located at the top of the four rotating shafts 6, and the diameters of the limit heads 7 are all larger than the diameters of the mounting holes 5. The bottom of the rotating shaft 6 is fixedly connected to a limit block 8. The limit block 8 is provided with a mounting groove 9 on the inner side near the top core body 3. The bottom of the mounting groove 9 is fixedly connected to a limit spring 10. The top of the limit spring 10 is fixedly connected to the limit spring 10. The top of the ceiling frame 1 is fixedly connected with a fixing ring 11, and the interior of the fixing ring 11 is fixedly connected with a limiting pin 12, and the bottom of the limiting pin 12 is fixedly connected with a pull block 13. A connecting groove 2 is provided on the middle side of the bottom of the ceiling frame 1, and a top core body 3 is clamped inside the connecting groove 2. The shape and size of the top core body 3 are adapted to the shape and size of the connecting groove 2, and the top core body 3 fits tightly against the inner wall of the connecting groove 2. Positioning holes 4 are provided around the bottom of the top core body 3, and the position of the positioning hole 4 corresponds to the position of the limiting pin 12. The limiting pin 12 is adapted to the inner wall diameter of the positioning hole 4, and the limiting pin 12 fits tightly against the inner wall of the positioning hole 4.

[0026] Working principle: When in use, the staff first installs the ceiling frame 1 to the top of the elevator, then installs the top core body 3 into the connecting groove 2, and rotates the limit block 8 to the bottom of the top core body 3 so that the limit block 8 fits tightly with the bottom of the top core body 3, thereby limiting the movement of the top core body 3. When the limit block 8 drives the limit pin 12 to move into the positioning hole 4, the limit spring 10 resets and pushes the limit pin 12 into the positioning hole 4 through the fixing ring 11, thereby completely fixing the position of the top core body 3. Locked. When the top core body 3 needs to be replaced, the staff only needs to pull the pull block 13 downward, and the pull block 13 will drive the limit pin 12 to move down and then be pulled out from the positioning hole 4. At this time, the staff will rotate the limit block 8 to one side of the ceiling frame 1, so that it is away from the top core body 3, and release the lock on the top core body 3. At this time, the top core body 3 will come out of the connecting groove 2 under the action of gravity. At this time, the staff will install the new top core body 3 into the connecting groove 2, and repeat the above installation steps to complete the installation, and the replacement can be completed.

[0027] Compared with the related art, the utility model provides an elevator ceiling with convenient replacement of the top core, which has the following beneficial effects: by setting the connecting groove 2, the top core body 3, etc. for use, the limit block 8 is rotated to one side of the ceiling frame 1, so that it is away from the top core body 3, and the lock on the top core body 3 is released. The top core body 3 will fall out of the connecting groove 2 under the action of gravity. At this time, the staff will install the new top core body 3 to the connecting groove 2 to complete the replacement. There is no need to replace the decorative ceiling as a whole, which reduces the labor burden of the staff and is convenient for the staff to use.

[0028] Example 2:

[0029] Please refer to Figures 1-6. There are mounting holes 5 around the bottom of the ceiling frame 1. Several mounting holes 5 are rotatably connected to the inside of a rotating shaft 6. The top of the rotating shaft 6 is fixedly connected to a limiting head 7. There are several limiting heads 7. Several limiting heads 7 are respectively located on the top of four rotating shafts 6, and the diameters of several limiting heads 7 are larger than the diameter of the mounting hole 5. The bottom of the rotating shaft 6 is fixedly connected to a limiting block 8. The inside of the limiting block 8 near the side of the top core body 3 is provided with a mounting groove 9. The bottom of the mounting groove 9 is fixedly connected to a limiting spring 10. The top of the limiting spring 10 is fixedly connected to a fixing ring 11. The diameter of the fixing ring 11 is the same as the diameter of the mounting groove 9, and the fixing ring 11 fits with the inner wall of the mounting groove 9. The inside of the fixing ring 11 is fixedly connected to a limiting pin 12, and the bottom of the limiting pin 12 is fixedly connected to a pull block 13.

[0030] Working principle: By rotating the limit block 8 to the bottom of the top core body 3, the limit block 8 is tightly fitted with the bottom of the top core body 3, thereby limiting the movement of the top core body 3. When the limit block 8 drives the limit pin 12 to move into the positioning hole 4, the limit spring 10 is reset and pushes the limit pin 12 into the positioning hole 4 through the fixing ring 11, thereby completely locking the position of the top core body 3.

[0031] Compared with the related art, the utility model provides an elevator ceiling that is convenient for replacing the top core and has the following beneficial effects: by setting a positioning hole 4, a limit pin 12, etc. for use with a limit block 8, and by rotating the limit block 8 to the bottom of the top core body 3, the limit block 8 is tightly fitted with the bottom of the top core body 3, thereby limiting the movement of the top core body 3. At the same time, the limit pin 12 extends into the interior of the positioning hole 4 to increase the fixing effect, which is convenient for the staff to use.
