Buckled type compression-resistant extending-and-contracting rod used in building

建筑用扣接式抗压伸缩杆

Abstract

本发明公开了一种建筑用扣接式抗压伸缩杆,包括第一杆件和第二杆件,第一杆件设有凸条,第二杆件设有相匹配的滑槽,第一杆件与第二杆件通过凸条与滑槽的相互配合连接在一起。凸条沿其宽度的侧沿与滑槽的接触面为弧形曲面状,凸条具有第一弧形曲面,滑槽具有与凸条相配合的第二弧形曲面。采用上述结构后,本发明一种建筑用扣接式抗压伸缩杆的凸条沿其宽度的侧沿与滑槽的接触面为弧形曲面状,通过凸条的第一弧形曲面与滑槽的第二弧形曲面的相互配合,使得凸条与滑槽之间的相对滑动变得更加流畅。
The invention discloses a buckled type compression-resistant extending-and-contracting rod used in a building. The extending-and-contracting rod comprises a first rod piece and a second rod piece, the first rod piece is provided with a protruding strip, a matched sliding groove is formed in the second rod piece, and the first rod piece and the second rod piece are connected together through mutual cooperation between the protruding strip and the sliding groove. The face, in contact with the sliding groove, of the side edge in the protruding strip in the width direction is in an arc-shaped curved-face shape, the protruding strip is provided with a first arc-shaped curved face, and the sliding groove is provided with a second arc-shaped curved face matched with the protruding strip. By the adoption of the structure, the face, in contact with the sliding groove, of the side edge in the protruding strip of the buckled type compression-resistant extending-and-contracting rod used in the building in the width direction is in the arc-shaped curved-face shape, and through mutual cooperation between the first arc-shaped curved face of the protruding strip and the second arc-shaped curved face of the sliding groove, relative sliding between the protruding strip and the sliding groove can be more smooth and easier.
