The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.

A high-performance square and rectangular tube is shown in figures 1 to 4 and comprises a square and rectangular tube body 1 and a buffer support structure at the inner side of the square and rectangular tube body;

the buffer support structure comprises a herringbone support frame 2 arranged in the square tube body, a transition plate 3 is arranged on the inner wall of the top edge of the square tube body, and the top of the support frame is fixed on the transition plate;

a included angle formed by the bottom edge and the side edge of the square tube body is provided with a slow pressing plate 4, and two sides of the slow pressing plate are respectively fixed on the bottom edge and the corresponding side edge;

two support legs 5 are arranged at the lower part of the support frame, and the bottom end of each support leg is fixed on the slow pressing plate on the corresponding side. The pressure relief plate is generally of an arc structure, and the arc center of the pressure relief plate is positioned on one side of the center of the square tube body. The pressure buffering plate can have certain deformation capacity after the square tube is impacted or vibrated.

The transition plate is of an arc-shaped structure, the arc center of the transition plate is positioned on one side different from the center of the square tube body, namely the opening side is upward, and the arc center is positioned above the square tube, so that the buffer performance of the transition plate can be effectively exerted.

Each support piece 7 is arranged between the support leg and the top plate, and the lower end of the support frame is arranged at a position corresponding to the fixing position of the reinforcement piece and the support leg. The support is generally vertically disposed.

In an alternative embodiment, as shown in fig. 3, a reinforcement 6 is provided between the legs. Generally, the reinforcing member is a plate-shaped structure, and before the buffer support structure is fixed in the square tube, the reinforcing member (plate) is horizontally welded and fixed between the two supporting legs, that is, the left side of the reinforcing member is welded and fixed on the left side of the supporting leg, and the right side of the reinforcing member is welded and fixed on the right side of the supporting leg.

The transition plate is of an inverted omega-shaped structure and comprises an arc-shaped buffer part 8 and connecting parts 9 on two sides of the buffer part; the connecting part is attached to the inner wall of the top edge of the square tube body, and a transition structure is arranged between the connecting part and the buffering part, in an optional embodiment, the transition structure can adopt a round angle, as shown in fig. 3, and the connecting part and the buffering part are transited through a round angle 10.

In another alternative embodiment, as shown in fig. 2, an inclined transition portion 11 is provided between the connecting portion and the cushioning portion, and both ends of the transition portion are smoothly transited to the connecting portion and the cushioning portion respectively. Just because the transition structure between connecting portion and buffering portion two parts, under the normality, the transition structure is not laminated with the topside, can laminate with the topside again when receiving, has guaranteed the good deformability of transition board, when the square tube receives the impact or vibrations, allows it to produce certain deformation, plays good buffering shock-absorbing capacity.

The connecting part is welded and fixed on the inner wall of the top edge of the square tube body. It should be noted that, it is not necessary to weld all the materials, and it is generally sufficient to weld (spot weld) the pipe orifice portions near the two ends of the square tube, and it should be noted that, the length of the square tube generally applied to the fixing frame is a section, and is not infinite long, as long as the buffering support structure can be maintained, so that the buffering support structure can exert the buffering performance. Meanwhile, the product processing difficulty is low, the square tube has better buffering and damping performance, and the capability of resisting impact and vibration is stronger.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
