[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Example

[0021] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, Figure 1 Shown is an overall schematic diagram of the steel grating in the embodiment; Figure 2 Shown is a cross schematic diagram of flat steel 1 and flat steel 2 in the embodiment; Figure 3 The figure shows a schematic diagram of the structure of the cooperation between the first flat steel and the second flat steel in the embodiment; Figure 4 The figure shows a schematic diagram of the structure of the flat steel and the fixing assembly in the embodiment;

[0022] The device includes:

[0023] The surrounding steel 10 has a flat steel 11 and a flat steel 2 12 arranged inside. The flat steel 11 and the flat steel 2 12 are arranged crosswise. The flat steel 2 12 has a plurality of slots 13 equidistantly opened along the length direction. The flat steel 11 is engaged with the slots 13.

[0024] The fixing assembly 20 includes a pair of fixing blocks 21 arranged on the flat steel 12, and a second card slot 22 located on the same straight line as the card slot 13 is formed between the pair of fixing blocks 21. The flat steel 12 is also engaged in the second card slot 22. The fixing blocks 21 are movably provided with a stopper 24 at one end close to the flat steel 11. When the flat steel 11 is embedded in the card slot 13 and the second card slot 22, the stopper 24 is located above the flat steel 11. The stopper 24 can limit the flat steel 11 from leaving the second card slot 22.

[0025] A mounting groove 23 is provided at one end of the fixed block 21 close to the flat steel 11, and a stopper 24 is slidably provided in the mounting groove 23. A spring 25 is also provided in the mounting groove 23, and both ends of the spring 25 are fixedly connected to the stopper 24 and the side wall of the mounting groove 23 respectively.

[0026] Specifically, flat steel 11 and flat steel 2 12 are perpendicular to each other, and the ends of flat steel 11 and flat steel 2 12 close to the surrounding steel 10 are welded and fixed to the surrounding steel 10; and the surrounding steel 10, flat steel 1 11 and flat steel 2 12 are all made of stainless steel metal material; the card slot 13 and the card slot 2 22 are matched with the shape of flat steel 11.

[0027] By providing a plurality of slots 13 equidistantly along the length direction on the flat steel 12, the flat steel 11 can be positioned and installed. By providing a fixing assembly 20, the flat steel 11 can be further fixed after being engaged with the slots 13. The movable block 24 can enable the flat steel 11 to be quickly installed or removed.

[0028] During installation, by squeezing the stopper 24 with the flat steel 11, the stopper 24 can compress the spring 25 and enter the installation groove 23. At this time, the flat steel 11 can be smoothly engaged with the slot 13 and the slot 2 22. After the engagement is completed, the spring 25 is reset, which drives the stopper 24 to extend and abut against the top of the flat steel 11, further fixing the flat steel 11 and preventing the flat steel 11 from leaving the slot 2 22.

[0029] When removing one of the flat steels 11, when the flat steel 11 and the surrounding steel 10 are disconnected, the flat steel 11 can be separated from the slot 13 and the slot 2 22 by external force, without having to disassemble the entirety for replacement.

[0030] Specifically, in order to ensure the overall strength of the steel grating, further welding can be performed at the intersection of flat steel 11 and flat steel 2 12, which can be determined based on the specific application scenario.

[0031] Working principle: This device plays the role of positioning and installing flat steel 11 by opening multiple slots 13 equidistantly along the length direction on flat steel 12. The fixed component 20 can further fix the flat steel 11 after the flat steel 11 is engaged with the slot 13, and the movable block 24 can make the flat steel 11 quickly installed or disassembled.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
