[0023] See also Figure 1-Figure 3 The utility model provides a technical solution: a grating assembly device, comprising a plurality of grating bars 2, wherein the plurality of grating bars 2 are arranged in sequence from top to bottom, and the right ends of two adjacent grating bars 2 are rotatably connected by a rotating shaft, and an adjustment mechanism 1 is installed on the grating bar 2 for facilitating the uniform arc arrangement of the grating bars 2;

[0024] The adjustment mechanism 1 includes two connecting blocks 11, an adjustment component 12, an arc component 13 and a limit component 14. The left side of the bottom end of the connecting block 11 at the top is rotatably connected to the grating bar 2 at the top through a rotating shaft, and the left side of the top end of the connecting block 11 at the bottom is rotatably connected to the grating bar 2 at the bottom through a rotating shaft. The adjustment component 12 is installed on the connecting block 11, and the arc component 13 is installed on the connecting block 11. The limit component 14 is installed on the arc component 13, and one side of the limit component 14 is connected to the grating bar 2, which is convenient for changing the plane and arc of the grating bar 2, and is convenient for shaping and simple to operate.

[0025] The adjusting assembly 12 includes a slide 121, a slider 122, a threaded rod 123, a rotating frame 124, a bracket 125 and a slide bar 126. The front end face of the connecting block 11 at the top is fixedly connected to the slide 121. A limiting groove is provided inside the slide 121. The inner side wall of the limiting groove is slidably connected to the slide 122. The bottom end of the slide 122 is rotatably connected to the threaded rod 123 through a rotating shaft. The bottom end of the threaded rod 123 is fixedly connected to the rotating frame 124. The rear end face of the rotating frame 124 is fixedly connected to the connecting block 11 at the bottom. The rear end face of the connecting block 11 is fixedly connected to the bracket 125. The bottom end of the bracket 125 at the top is fixedly connected to the slide bar 126. The outer side of the slide bar 126 is fixed to the bottom end. The bracket 125 at the end is slidably connected, and the grating bar 2 is a separate grating bar. When the arc-shaped airbag 132 is not inflated, the threaded rod 123 is rotated in the rotating frame 124, and the threaded rod 123 rotates on the slider 122. The bracket 125 slides inside the slide bar 126 at the bottom end to limit the movement of the bottom connecting block 11. The rotation of the threaded rod 123 drives the rotating frame 124 away from the slider 122, thereby making the two connecting blocks 11 move away from each other. The fixing frame 131 fixes the top of the arc-shaped airbag 132. The arc-shaped airbag 132 is elastic. The two connecting blocks 11 move away from each other so that the grating bars 2 can move to each other to be located in the same plane, which facilitates the grating bars 2 to form a plane.

[0026] It should be noted that the center of the original arc of the arc-shaped airbag 132 and the center of the arc of the required combination of the grating bar 2 are the same point. The threaded rod 123 rotates on the turntable 124 at a set point. Each rotation, whether the grating bar 2 requires an arc combination to make the two connecting blocks 11 close to each other, or the grating bar 2 requires a plane combination to make the two connecting blocks 11 move away from each other, is a fixed point. The position of the threaded rod 123 rotating on the turntable 124 is fixed.

[0027] The arc assembly 13 includes a fixing frame 131, an arc-shaped airbag 132, a limiting frame 133 and a valve 134. The top of the connecting block 11 at the top is fixedly connected to the fixing frame 131, and the inner side of the top of the fixing frame 131 is fixedly connected to the arc-shaped airbag 132. The arc-shaped airbag 132 is an elastic hollow arc-shaped structure. The other end of the arc-shaped airbag 132 is slidably connected to the limiting frame 133. The top of the limiting frame 133 is fixedly connected to the connecting block 11 at the bottom end, and the bottom end of the limiting frame 133 is fixedly connected to the valve 134. A slide groove is provided on the inside of the limiting frame 133, and the outer side of the arc-shaped airbag 132 is slidably connected to the slide groove. A through groove is provided on the inside of the limiting frame 133, and the threaded rod 123 is provided on the inside of the through groove. The limiting assembly 14 includes a limiting ring 141 and a rotating block 142. The right end of the arc-shaped airbag 132 is fixedly connected to The limiting ring 141 and the front end surface of the grating bar 2 are fixedly connected with a rotating block 142, and the inner side of the limiting ring 141 is rotatably connected to the rotating block 142 through a rotating shaft. When a special combination of the grating bars 2 is required to be arc-shaped, the two connecting blocks 11 are driven to approach each other by rotating the threaded rod 123, and the two connecting blocks 11 are adjusted to a suitable position. An air pump is used to pump air into the arc-shaped airbag 132 through the rotating frame 124. The arc-shaped airbag 132 is inflated so that the arc-shaped airbag 132 bulges. The arc-shaped airbag 132 itself is arc-shaped, so that the arc-shaped airbag 132 drives the rotating block 142 to move through the limiting ring 141, and the rotating block 142 drives the corresponding grating bar 2 to move, so that the grating bar 2 adjustment combination is set in an arc shape, which is convenient for special grating combination operations, convenient for changing the plane and arc of the grating bar 2, and convenient for shaping, and simple to operate.

[0028] Working principle:

[0029] When the device is in use, the grating bar 2 is a separate grating bar. When the arc-shaped airbag 132 is not inflated, the threaded rod 123 is rotated in the rotating frame 124, and the threaded rod 123 rotates on the slider 122. The bracket 125 slides inside the slider 126 at the bottom to limit the movement of the bottom connecting block 11. The rotation of the threaded rod 123 drives the rotating frame 124 away from the slider 122, thereby causing the two connecting blocks 11 to move away from each other. The fixing frame 131 fixes the top of the arc-shaped airbag 132. The arc-shaped airbag 132 is elastic. The two connecting blocks 11 move away from each other so that the grating bar 2 can move to each other until they are in the same plane. To facilitate the grating bars 2 to form a plane, when a special combination of the grating bars 2 is required to be arc-shaped, the two connecting blocks 11 are driven closer to each other by rotating the threaded rod 123, and the two connecting blocks 11 are adjusted to a suitable position. An air pump is used to pump air into the arc-shaped airbag 132 through the rotating frame 124. The arc-shaped airbag 132 is inflated so that the arc-shaped airbag 132 bulges. The arc-shaped airbag 132 itself is arc-shaped, so that the arc-shaped airbag 132 drives the rotating block 142 to move through the limiting ring 141, and the rotating block 142 drives the corresponding grating bars 2 to move, so that the grating bars 2 are adjusted and combined to be set in an arc shape, which is convenient for special grating combination operations.

[0030] When other combinations are needed, the slider 122 can be slid out of the limiting groove of the adjustment mechanism 1. The arc-shaped airbag 132 is elastic, and then the slide rod 126 can be pulled out from the bracket 125 at the bottom end.
