Detailed Description

The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.

The specific embodiment is as follows: referring to fig. 1-3, a matching structure of a beam and a ferrule nut for a photovoltaic bracket is shown, and comprises a beam 1 and the ferrule nut 2, wherein the beam 1 comprises a bottom plate 11, two sides of the bottom plate 11 are respectively provided with a side plate 15 perpendicular to the bottom plate 11, one end of the side plate 15 far away from the bottom plate 11 is provided with a top plate 13 on the inner side, one end of the top plate 13 far away from the side plate 15 is provided with an inner folded plate 12 on the side close to the bottom plate 11, and an air space 14 is formed between the two inner folded plates 12. The center of the cutting sleeve nut 2 is provided with a threaded hole 22, the cutting sleeve nut 2 is rectangular in top view, the width of the cutting sleeve nut 2 is smaller than the width of the hollow space 14, the length of the cutting sleeve nut is larger than the width of the hollow space 14 and smaller than the distance between the two side plates 15, the length of a diagonal line of the rectangle is larger than the distance between the two side plates 15, and the group of diagonal lines of the cutting sleeve nut 2 are fillets 21, so that the distance from the edges of the fillets 21 to the axis of the threaded hole 22 is not larger than one half of the distance between the two side plates 15. When the clamping sleeve nut 2 is used, the beam 1 is taken as a ground beam as an example, firstly, bolts downwards penetrate through holes in the column base and then are connected with threaded holes 22 in the clamping sleeve nut 2, at the moment, the clamping sleeve nut 2 is positioned outside the beam 1, so that connection is easy, then the extending direction (length direction) of the clamping sleeve nut 2 is basically parallel to the extending direction of the beam 1, then the clamping sleeve nut 2 is downwards placed into the beam 1 from the upper direction of an empty side 14 in fig. 3 (without penetrating from one end of the beam 1), because the clamping sleeve nut 2 is placed into the beam 1 through the empty side 14, when the fixing position of the clamping sleeve nut 2 is far away from the end of the beam, the column base can be quickly placed to a preset position, at the moment, the clamping sleeve nut 2 is positioned between a folded plate 12 and a bottom plate 11, then the bolts are screwed, at the beginning of screwing, the clamping sleeve nut 2 is not blocked by contact with the beam 1, and the bolts, because the bolts are normally positive threads, the round corners 21 are arranged in the direction facing the direction when the bolts and the clamping sleeve nut 2 are clockwise, the two round corners are turned, the round corners 21 are not contacted with the two round corners 21, and the two round corners are not tightly contacted with the threaded holes 15 when the two round corners 2 are further, and the two round corners are not tightly contacted with the round corners 21, and the round corners are further screwed with the round corners and the round edges and the round corners are further are screwed. The length of the ferrule nut 2 is preferably slightly smaller than the distance between the two side plates 15, so that it is nearly perpendicular to the beam 1 when the ferrule nut 2 cannot continue to rotate, so that the part of the ferrule nut 2 that is in contact with the inner flap 12 is closer to the threaded hole 22.

Preferably, the two ends of the surface of the ferrule nut 2 facing the hollow space 14 are provided with bosses 23, the inner sides of the bosses 23 are inclined planes 231, so that the width of the top surface of the boss 23 is smaller than that of the bottom surface of the boss, the two inner folded plates 12 are perpendicular to the bottom plate 11, the distance between the inner sides of the tops of the two bosses 23 is larger than that between the outer side surfaces of the two inner folded plates 12, and the distance between the inner sides of the bottoms of the two bosses 23 is slightly smaller than that between the outer side surfaces of the two inner folded plates 12, in which case, the length of the ferrule nut 2 is equal to or slightly smaller than that between the two side plates 15. When the bolt is tightened, the inclined surface 231 contacts with one bottom edge of the inner folded plate 12 near the side plate 15 and generates push-pull in the direction of the threaded hole 22, so that the side plate 15 is not easy to incline outwards.
