[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example

[0027] See also Figure 1-9 This embodiment provides an adjustable grille connection device, including an embedded plate 1, such as Figure 1 and Figure 6 As shown, the embedded plate 1 is composed of a plate body and connecting rods, and one end face of the plate body is fixedly connected with a plurality of connecting rods. When the wall is cast, the connecting rods are embedded in the wall surface, and the embedded plate 1 can be installed on the wall surface. A bent plate 2 is welded on the end face of the embedded plate 1 away from the wall surface, and the bent plate 2 is set as a bent hot-dip galvanized steel plate.

[0028] like Figure 2 As shown, through holes are provided on both sides of the bending plate 2, and gaskets 5 are welded at the through holes on the outer wall of the bending plate 2, and the gaskets 5 are provided with slots in the shape of strips. Figure 1 As shown, the bending plate 2 is penetrated by a bolt 4, wherein one end of the bolt 4 penetrates through a slot of a gasket 5 and passes through the through hole of the bending plate 2 from the slot of another gasket 5, and one end of the bolt 4 that passes through is threadedly connected with a support nut 42, and the bolt 4 can be longitudinally slidably adjusted in the slot, and the bolt 4 can be fixed by tightening the support nut 42 to cooperate with the screw head of the bolt 4.

[0029] When tightening the support nut 42, if the tightening force is too large, the screw head of the bolt 4 and the support nut 42 will form an extrusion force, thereby squeezing the two sides of the bending plate 2, causing the bending plate 2 to bend and deform. In order to prevent the bending plate 2 from deforming, Figure 5 As shown, the middle part of the bolt 4 is also threadedly connected with two support nuts 42. After the position of the bolt 4 is confirmed, the two support nuts 42 in the middle are rotated so that the two support nuts 42 are respectively attached to the inner side walls of the bending plate 2. At this time, the two support nuts 42 in the middle are supported inside the bending plate 2 to prevent the support nuts 42 farthest from the screw head of the bolt 4 from being tightened and generating an extrusion force that will bend the bending plate 2.

[0030] A single plate 7 is installed at one end of the bending plate 2. Figure 1 As shown, a hook 3 is welded at one end of the single plate 7, and the hook 3 is set to be anodized aluminum alloy, and the hook 3 is connected to the square tube 6 by a core-pulling rivet, and the hook 3 is hooked on the bolt 4. The single plate 7 can be installed on the embedded plate 1 by hooking the hook 3 on the bolt 4. In order to adjust the position of the single plate 7, the bolt 4 can be slid longitudinally in the slot of the gasket 5, and the bolt 4 can slide to adjust the distance between the single plate 7 and the embedded plate 1, and the support nut 42 with one end of the bolt 4 away from the bolt 4 head can be tightened to fix the distance between the single plate 7 and the embedded plate 1. By sliding the bolt 4 on the hook 3, the position of the single plate 7 can be adjusted by horizontal movement. In order to fix the horizontal position of the single plate 7, the bolt 4 is also threaded with a positioning nut 41 for fixing the position of the hook 3, wherein the positioning nut 41 is set to two, and the positioning nut 41 has two ways of fixing the hook 3. The first is that the two positioning nuts 41 are located on both sides of the side wall of the hook 3, and the two positioning nuts 41 are rotated close to the two positioning nuts 41, so that the two positioning nuts 41 clamp one side wall of the hook 3, thereby fixing the hook 3. Another method is to locate the two positioning nuts 41 inside the hook 3 , and rotate the positioning nuts 41 so that the two positioning nuts 41 are respectively attached to the inner side walls of the hook 3 , thereby limiting the position of the hook 3 .

[0031] like Figure 4 As shown, the single board 7 is configured as a hollow structure. In order to increase the structural strength of the single board 7, a square tube 6 is fixedly installed inside the single board 7. The square tube 6 is configured as an anodized aluminum alloy tube. The square tube 6 is supported inside the single board 7, thereby increasing the structural strength of the single board 7.

[0032] In strong wind weather, the strong wind will exert pressure on the single board 7. When the wind is upward, the strong wind will push the single board 7 upward, thereby causing the hook 3 to be separated from the bolt 4, and then causing the single board 7 to be separated from the wall. In order to prevent the hook 3 from being separated from the bolt 4, a limiting mechanism 8 for limiting the hook 3 is installed inside the hook 3, wherein the limiting mechanism 8 includes a horizontal plate 81, a clamping block 82 and a pressing block 83, as shown in FIG. Figure 7 , Figure 8 and Fig. 9 As shown, the horizontal plate 81 is fixedly installed inside the hook 3, the clamping block 82 is slidably inserted in the horizontal plate 81, and one end of the clamping block 82 extends from one end of the horizontal plate 81. After the hook 3 is hooked on the bolt 4, the extended end of the clamping block 82 is located below the bolt 4, thereby limiting the hook 3. The upper end of the horizontal plate 81 is threadedly connected with a screw rod 831, and the pressing block 83 is slidably installed inside the horizontal plate 81. The lower end of the screw rod 831 extends into the horizontal plate 81 and is rotatably connected to the upper end of the pressing block 83. The pressing block 83 can be slid up and down in the horizontal plate 81 by rotating the screw rod 831. The ends of the clamping block 82 and the pressing block 83 that are close to each other are both set as inclined surfaces, and the inclined surfaces of the clamping block 82 and the pressing block 83 fit each other. After the pressing block 83 is moved downward by rotating the screw 831, the inclined surface of the pressing block 83 applies pressure to the inclined surface of the clamping block 82, thereby driving one end of the clamping block 82 to extend from one end of the cross plate 81. The extended clamping block 82 can limit the hook 3 to prevent the hook 3 from detaching from the bolt 4.

[0033] When removing the single board 7, the hook 3 needs to be separated from the bolt 4. Figure 8 and Fig. 9 As shown, a spring 821 is fixedly installed at the lower end of the horizontal plate 81, and a convex plate is fixedly connected to one side below the clamping block 82. One end of the spring 821 is fixedly connected to the convex plate, and an elastic force is applied to the convex plate through the spring 821. After the screw 831 is rotated to move the pressing block 83 up and down, the spring 821 applies an elastic force to the convex plate, and the clamping block 82 is driven to shrink into the horizontal plate 81 through the convex plate, so that the limit on the hook 3 can be cancelled. At this time, the hook 3 can move upward to disengage from the hook 3, and the single board 7 can be disassembled.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
