Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0026] EMBODIMENT

[0027] Please refer to Figures 1-5, the present utility model provides a technical solution: a clamping type pedal grid for a boiler flat ladder, including a grid plate 1. A rubber block 10 is fixedly installed on the top surface of the grid plate 1. The rubber blocks 10 are evenly distributed on the top surface of the grid plate 1. The rubber blocks 10 can increase the friction between the user's sole and the top surface of the grid plate 1, thus playing an anti-slip role, avoiding the phenomenon of slipping when the user walks on the top surface of the grid plate 1 with water, reducing the probability of safety accidents, and improving the safety performance. A connecting block 2 is fixedly installed on one side of the grid plate 1. A magnet B12 is fixedly installed on the side surface of the connecting block 2. A connecting groove 3 is opened on the other side of the grid plate 1. A magnet A11 is fixedly installed on the inner wall of the connecting groove 3. The opposite surfaces of the magnet A11 and the magnet B12 are the S pole and the N pole respectively. The magnet A11 and the magnet B12 can attract each other. When fixing the connecting block 2 and the connecting groove 3, it can play a positioning and fixing effect, thereby improving the alignment efficiency of the connecting block 2 and the connecting groove 3, and further improving the assembly efficiency. Claw slots 9 are opened on the inner wall of the connecting groove 3 and the surface of the connecting block 2. The shapes and sizes of the claw slots 9 and the clamping blocks 701 are all adapted to each other. The numbers of the connecting blocks 2 and the connecting grooves 3 are both two groups. The shapes and sizes of the two groups of connecting blocks 2 and connecting grooves 3 are all matched. A limiting groove 4 is opened on the top surface of the grid plate 1. The limiting groove 4 can limit the pressing plate 704 and at the same time facilitate the sliding of the pressing plate 704. A long groove 5 is opened inside the grid plate 1. A sliding groove 6 is opened on the inner wall of the long groove 5. A positioning component 7 is arranged inside the long groove 5. The positioning component 7 includes a clamping block 701. A connecting rod 702 is fixedly installed on the side surface of the clamping block 701. The connecting rod 702 is slidably connected with the sliding groove 6, facilitating the movement of the connecting rod 702. One end of the connecting rod 702 is fixedly installed with a sliding block 703. The sliding block 703 is slidably connected with the sliding rod 8, facilitating the movement of the sliding block 703. The top end of the sliding block 703 is fixedly installed with a pressing plate 704. The pressing plate 704 is slidably connected with the limiting groove 4, facilitating the movement of the pressing plate 704. A tension spring 705 is fixedly installed on the side surface of the sliding block 703. The tension spring 705 is sleeved on the surface of the sliding rod 8. One end of the tension spring 705 is fixedly connected with one side of the sliding block 703. The other end of the tension spring 705 is fixedly connected with the inner wall of the long groove 5. When the tension spring 705 automatically restores without external force, it is convenient to drive the sliding block 703 to reset, thereby pulling the connecting rod 702 to drive the clamping block 701 to insert into the inside of the claw slot 9, and further fixing the connecting block 2 and the connecting groove 3. The positioning components 7 are symmetrically distributed inside the long groove 5 and can fix the two groups of connecting blocks 2, making the connection between the grid plates 1 stronger. A sliding rod 8 is fixedly installed on the inner wall of the long groove 5.

[0028] Working principle: When assembling the grid plate 1, first take two groups of grid plates 1 and place them on the ground, making the connecting blocks 2 of the two groups of grid plates 1 face the connecting grooves 3. Then manually pinch the pressing plate 704. When the pressing plate 704 slides in the limiting groove 4, it drives the slider 703 to move. The slider 703 slides on the surface of the sliding rod 8. At the same time, the slider 703 drives the tension spring 705 to move and drives the connecting rod 702 to slide in the sliding groove 6. At this time, the connecting rod 702 drives the clamping block 701 to move until the clamping block 701 disengages from the clamping groove 9. Then, the connecting block 2 is engaged with the connecting groove 3, so that the magnet A11 attracts the magnet B12. At this time, release the hand pinching the pressing plate 704. The tension spring 705 loses the external force and pulls. Due to its own tensile force, it drives the slider 703 to slide on the surface of the sliding rod 8. At the same time, the slider 703 drives the connecting rod 702 to move, and the connecting rod 702 drives the clamping block 701 to move until the tension spring 705 is completely restored. At this time, the clamping block 701 can be inserted back into the clamping groove 9 through the connecting block 2, and the two groups of grid plates 1 are fixed. Repeating the above operations can fix multiple groups of grid plates 1.

[0029] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
