The utility model relates to a support and hanger system of a construction machine, and discloses a special lock for the support and hanger system. The locking device provided by the utility model includes nuts and bolts fixed with nuts, and also includes a top plate and a U-shaped clamp. The center position of the top plate is provided with a thread hole adapted to the bolt, and the top plate can be rotatably connected with the bolt through the thread hole; the middle depression of the U-shaped clamp is provided with a through hole adapted to the bolt end, and the U-shaped clamp is rotatable at the bolt end through the through the through hole. The screw cap moves up and down between the nut and the U-shaped clamp, and the surface edge of the top plate is provided with an anti-skid groove. When the channel steel is impacted by the force from the axial and radial direction, the design of the anti-skid groove can prevent the separation of the top plate from the channel steel, and then prevent the collapse of the support and hanger system and the occurrence of safety accidents; and because of the layout design of the diamond raised side with high side and low side, the deformation of the channel steel can be corrected and the accidents caused by the deformation of the channel steel can be eliminated.

一种支吊架系统专用锁扣
本技术涉及建筑机电支吊架系统,尤其涉及了一种支吊架系统专用的锁扣。
技术介绍
目前,在建筑系统中的机电线路大多需要采取防震减震措施,而锁扣则是采取防震减震措施中经常用到的关键零部件,锁扣多与U型槽钢配合使用,但是现有的锁扣多采用冷冲成型,且齿槽没有适应槽钢因受运输、搬运、切割等外力影响及自身加工应力释放变形的范围,一旦槽钢因各种因素变形,锁扣齿牙与槽钢齿牙不能完全咬合,导致支吊架系统坍塌事故屡屡发生,酿成重大安全隐患事故,严重威胁到生命财产安全。
技术实现思路
为了克服现有技术的不足,本技术的目的在于提供一种支吊架系统专用的锁扣,该锁扣能与U型槽钢紧密配合,连接可靠;并且能纠正槽钢的形变,杜绝了因槽钢的形变而产生的事故。本技术的目的采用如下技术方案实现:一种支吊架系统专用锁扣,包括螺帽和与所述螺帽固定连接的螺栓,还包括顶紧板和U形夹,所述顶紧板中心位置设有与所述螺栓适配的螺纹孔,所述顶紧板通过所述螺纹孔与所述螺栓可转动连接;所述U形夹的中段凹陷部设有与所述螺栓端部适配的通孔,所述U形夹通过所述通孔可转动的设于所述螺栓端部;所述顶紧板可在所述螺帽与所述U形夹之间作上下运动,所述顶紧板上表面边缘设有防滑槽,所述防滑槽内设有菱形凸起,所述菱形凸起相互交错排列于所述防滑槽内,所述菱形凸起带有坡度。进一步地,所述防滑槽对称设于所述顶紧板上表面,所述防滑槽为矩形防滑槽。进一步地,所述矩形防滑槽的宽度为0.4cm-1.0cm。进一步地,所述螺栓上套设有压缩弹簧,所述压缩弹簧设于所述顶紧板与所述U形夹之间。压缩弹簧对顶紧板向上顶紧,并始终对顶紧板施加力,当 ...
