In the actual installation process, after the nut plate 221 is rotated to the proper position, the second connecting end of the claw arm 211 and the rib leg 212 are sequentially inserted through the first connecting hole and the second connecting hole, the elastic pad 227 and the flat pad 228 are sleeved on the top of the rib leg 212, then the flat pad 228 is rotated to the position of the non-installation opening, and finally, after the adjusting bolt 223 is tightened, the elastic pad 227 and the flat pad 228 are clamped between the lower surface of the nut plate 221 and the top of the rib leg 212. It can be understood that after the flat pad 228 is provided, the stress area of the rib leg 212 and the nut plate 221 can be effectively increased, and a certain protection effect is provided for the rib leg 212, thereby being beneficial to further improving the fastening stress performance of the connection structure of the cross rod piece on the rod piece. In addition, the elastic pad 227 is designed to provide a certain elastic movement space between the flat pad 228 and the nut plate 221 during the tightening process of the adjusting bolt 223, so as to facilitate the installation of the flat pad 228.
In this embodiment, the spring pad 227 is shaped like a flat pad 228 and has a disc shape with a uniform diameter, and the first mounting hole 227a and the second mounting hole 228a are shaped like a special hole with a notch for the rib leg 212 to pass through. However, the design is not limited thereto, and in another embodiment as shown in fig. 5 and 6, the elastic pad 227 may also be a simple elastic ring with an opening, and the outer ring diameter of the elastic pad 227 is smaller than or equal to that of the flat pad 228, but the inner ring diameter thereof is larger than or equal to that of the second mounting hole 228 a.
Further, to facilitate twisting of the flat pad 228, a plurality of force ports 228b are provided at the outer periphery of the flat pad 228. As shown in fig. 4, the force openings 228b are notches formed at the outer periphery of the flat pad 228, and the number of the force openings 228b is at least two, and preferably, they are uniformly spaced in the circumferential direction. Thus, when the flat pad 228 is placed on top of the rib feet 212, the force opening 228b can serve as a finger force point to assist the installer in twisting the flat pad 228 to a corresponding non-installation opening position.
Referring to fig. 2 and 3, in order to prevent corrosion between different materials, a first gasket 231 is disposed at a contact surface between one end of the connecting claw 210 far away from the bolt assembly 220 and the first rod 110, a second gasket 232 is disposed at a contact surface between the adjusting bolt 223 and the second rod 120, and the first gasket 231 and the second gasket 232 are made of a soft elastic material. Specifically, in the present embodiment, the first gasket 231 and the second gasket 232 are made of rubber, but in other embodiments, the first gasket and the second gasket may also be made of, but not limited to, silicon rubber or other materials.
Finally, the following use process of the connection structure of the cross rod piece is explained in detail: firstly, after the first rod 110 and the second rod 120 are ready, the connection claw 210 is placed at the intersection node of the first rod 110 and the second rod 120, and a first gasket 231 is arranged at the contact surface of the connection claw 210 and the first rod 110 to prevent different materials from being corroded with each other; then, after the connecting claw 210 is in place, the nut plate 221 is sleeved into each claw arm 211 until the rib feet 212 at the second connecting end extend out of the large hole portions 224a of the through holes 224, and the second gasket 232 is arranged at the contact surface of the nut plate 221 and the second rod piece 120; then, the nut disk 221 is twisted by the twisting force rod 225 on the nut disk 221, so that the claw arm 211 enters the small hole part 224b and is clamped on the top of the rib foot without falling off; then, the spring pad 227 and the flat pad 228 with the force port 228b are sleeved on the top of the rib foot 212, and the flat pad 228 is twisted to the position of the non-installation port by using the force port 228b, after the step is completed, the cross rod is basically fixed and is not completely fastened, at this time, two rod pieces can be subjected to secondary fine adjustment and alignment, after the secondary fine adjustment of all the rod pieces is completed, the adjusting bolt 223 can be finally screwed into the nut 222 in the nut plate 221 so as to fasten the adjusting bolt 223 with the nut 222, the final adjustment and screwing are completed, and after the adjusting bolt 223 is screwed, the cross rod piece is indicated to be installed, fastened and stressed.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
