[0021] like Figures 1 to 5 As shown, a steel grating that is easy to disassemble includes a steel grating body 1 and a mounting seat 2, wherein the steel grating body 1 is arranged on the mounting seat 2, a placement groove 3 is provided on the upper surface of the mounting seat 2, the placement groove 3 matches the steel grating body 1, an opening 4 for drainage is provided at the bottom of the placement groove 3, a fixing component is provided on the side wall of the placement groove 3, an unlocking component is provided in the steel grating body 1, and the unlocking component is arranged corresponding to the fixing component.

[0022] The fixing assembly includes a limit pin 5, which is relatively arranged at both side walls of the placement groove 3, and the limit pin 5 is horizontally movably arranged in the mounting seat 2. The inner end of the limit pin 5 is fixedly connected to the limit block 6, and the limit block 6 is movably arranged in the slide groove 7. A locking spring 8 is arranged in the slide groove 7. The outer end surface of the limit pin 5 is an inclined surface protruding outward from the bottom, and the upper end of the outer end surface of the limit pin 5 is connected with the side wall of the placement groove 3. When the steel grating body 1 is placed, it is squeezed by the steel grating body 1 and the locking spring 8 is compressed, and the limit pin 5 shrinks to the inner wall of the mounting seat 2. The side wall of the steel grating body 1 is provided with a limit hole 12 matching the limit pin 5. After the steel grating body 1 is placed, the limit hole 12 is aligned with the limit pin 5, and the locking spring 8 pushes the limit pin 5 into the limit hole 12 to complete the locking of the steel grating body 1. Limit bars are provided on both sides of the limit pin 5 to prevent the limit pin 5 from rotating.

[0023] The unlocking component includes a pressing plate 9, which is movably arranged in a horizontally arranged pressing groove 10. A push rod 11 is arranged on the side of the pressing plate 9 close to the fixing component. The push rod 11 is movably arranged in a limiting hole 12. The limiting hole 12 matches the limiting pin 5. A spring 13 is sleeved on the push rod 11. One end of the spring 13 is fixed in a reset groove 14, and the other end is fixedly connected to the pressing plate 9. When unlocking, the staff inserts their hands into the pressing groove 10 and pushes the pressing plate 9 to move the push rod 11 to both sides and push the limiting pin 5 out of the limiting hole 12.
