[0018] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] A temporary protective floor for a mid-fuselage comprises a splicing panel body 1 and a limit block 2. A limit groove 12 is provided on the bottom surface of one side of the splicing panel body 1 along the length direction of the splicing panel body 1. A limit block mounting groove 14 is provided on the top surface of one side of the splicing panel body 1 where the limit groove 12 is provided. A circular hole 15 is provided at the bottom of the limit block mounting groove 14. Two screw holes 22 are provided on one side of the limit block 2. A circular boss 21 of a limit metal block is provided on the bottom surface of the other side of the limit block 2. The limit block 2 is arranged in the limit block mounting groove 14, and the circular boss 21 of the limit metal block passes through the circular hole 15 and protrudes from the bottom surface of the limit groove 12. The limit block 2 is locked in the limit block mounting groove 14 by screws 4 passing through the screw holes 22.

[0021] The top surface of the splicing plate body 1 is symmetrically provided with handle mounting grooves 11 at both ends, and the handle mounting grooves 11 are fastened with screws 4 to the pulling handles 3 .

[0022] The lifting handle 3 includes an "Ω"-shaped plate 31 and a rectangular handle 32. One side rod of the rectangular handle 32 is nested in the middle protrusion of the "Ω"-shaped plate 31. The "Ω"-shaped plate 31 is fastened in the handle mounting groove 11 by screws 4. After the "Ω"-shaped plate 31 is fixed, the rectangular handle 32 is rotated to rotate the other side rod of the rectangular handle 32 out of the handle mounting groove 11. By holding the rectangular handle 32 with both hands, the splicing plate body 1 can be lifted and removed from the middle fuselage.

[0023] A splicing positioning groove 13 is provided in the middle of one side of the splicing plate body 1 where the limiting groove 12 is provided, for determining relative positions of adjacent splicing plate bodies 1 when splicing.

[0024] The screw hole 22 on the limiting block 2 is a screw hole with a boss 221 on the top, which is convenient for installing screws.

[0025] During use, the limit block 2 and the lifting handle 3 are installed on the splicing plate body 1 by means of screws 4. The circular boss 21 of the metal block exposed at the bottom of the splicing plate body 1 cooperates with the slide rail hole of the aircraft cabin seat to limit the temporary protective floor, thereby preventing the temporary protective floor from moving out of the required area. At the same time, the floor provides an operating platform for workers and provides safe support for operators to walk on it.
