固定扣件A的背面还转动连接有固定扣件B,这样可使的两根角度不同的脚手架进行连接,起到分摊物体重量的作用。The back of the fixed fastener A is also connected to the fixed fastener B by rotation, so that two scaffolds with different angles can be connected to share the weight of the object.
基于实施例1的一种脚手架用组合型扣件的工作原理是:工作人员将第一弧形管1和第二弧形管2放置到脚手架外径上,然后工作人员手动向内转动闭合第一弧形管1和第二弧形管2,使得管壁上的突出环4与脚手架外表面接触,再然后工作人员将螺栓C穿过开孔523与螺纹锁定块3进行连接,在螺栓C转动连接过程中,螺栓C不断向内移动带动空心圆盘526和固定环527向内挤压弹簧片524,弹簧片524在挤压过程中向螺栓C施加反作用力,使得螺栓C在锁紧时与螺纹锁定块3紧密贴合,从而有效的防止螺栓松动脱落。The working principle of a combined fastener for scaffolding based on Embodiment 1 is: the staff places the first arc-shaped tube 1 and the second arc-shaped tube 2 on the outer diameter of the scaffold, and then the staff manually rotates inward to close the first arc-shaped tube 1 and the second arc-shaped tube 2. The first arc-shaped tube 1 and the second arc-shaped tube 2 make the protruding ring 4 on the tube wall contact the outer surface of the scaffolding, and then the staff will pass the bolt C through the opening 523 and connect it to the threaded locking block 3, and then the bolt C During the rotational connection process, the bolt C continuously moves inward, driving the hollow disc 526 and the fixed ring 527 to squeeze the spring piece 524 inward. The spring piece 524 exerts a reaction force on the bolt C during the extrusion process, so that the bolt C is locked when the bolt C is tightened. It fits tightly with the thread locking block 3, thereby effectively preventing the bolts from loosening and falling off.
实施例二:Example 2:
请参阅图1~图5,本实用新型的一种脚手架用组合型扣件,相较于实施例一,本实施例还包括:受力装置53包括,受力装置外壳531固定连接于辅助机构外壳51左侧,螺纹孔532设置受力装置外壳531内部左侧,安装槽533设置于螺纹孔532右侧,螺纹柱534螺纹连接于螺纹孔532内部,连接柱535固定连接于螺纹柱534右端,压力块536固定连接于连接柱535右侧面,弧面537设置于压力块536右端。Please refer to Figures 1 to 5. A combined fastener for scaffolding of the present invention. Compared with the first embodiment, this embodiment also includes: a force-bearing device 53, and a force-bearing device shell 531 is fixedly connected to the auxiliary mechanism. On the left side of the shell 51, the threaded hole 532 is provided with the force-bearing device on the left side of the shell 531. The mounting groove 533 is provided on the right side of the threaded hole 532. The threaded column 534 is threadedly connected to the inside of the threaded hole 532, and the connecting column 535 is fixedly connected to the right end of the threaded column 534. , the pressure block 536 is fixedly connected to the right side of the connecting column 535, and the arc surface 537 is provided at the right end of the pressure block 536.
弧面537用于使螺栓C更容易进入安装槽533内部。The arc surface 537 is used to make it easier for the bolt C to enter the inside of the installation groove 533 .
压力块536采用具有韧性的复合塑料材质制作,用于贴合螺栓C的底端。The pressure block 536 is made of tough composite plastic material and is used to fit the bottom end of the bolt C.
本实施例中:螺栓C在与螺纹锁定块3连接过程中,螺栓C底端不断伸入安装槽533内部,因为压力块536在安装槽533内部所围成的圆形内径外大内小,所以位于安装槽533前侧的压力块536在接触到螺栓C时受到其向外的推压,使的压力块536在连接柱535上随着螺栓C进入深度不断向外扩展,导致螺栓C在安装槽533内部与压力块536紧密贴合,加大了螺栓C底端的受力面积,使螺栓C受力均匀不易发生形变。In this embodiment: when the bolt C is connected to the threaded locking block 3, the bottom end of the bolt C continuously extends into the installation groove 533, because the inner diameter of the circle formed by the pressure block 536 inside the installation groove 533 is larger on the outside and smaller on the inside. Therefore, the pressure block 536 located on the front side of the installation groove 533 is pushed outward by the bolt C when it contacts the bolt C, so that the pressure block 536 continues to expand outward on the connecting column 535 as the bolt C enters the depth, causing the bolt C to The inside of the installation groove 533 is in close contact with the pressure block 536, which increases the stress-bearing area at the bottom of the bolt C, making the bolt C evenly stressed and less likely to deform.
本实用新型通过改进提供一种脚手架用组合型扣件,设置防滑装置52位于辅助机构外壳51右侧、受力装置53位于辅助机构外壳51左侧,通过弹簧片524在挤压过程中向螺栓C施加反作用力,使得螺栓C在锁紧时与螺纹锁定块3紧密贴合,从而有效的防止螺栓松动脱落,并且通过螺栓C在安装槽533内部与压力块536紧密贴合,加大了螺栓C底端的受力面积,使螺栓C受力均匀不易发生形变。The utility model provides a combined fastener for scaffolding through improvements. The anti-slip device 52 is located on the right side of the auxiliary mechanism housing 51 and the force-receiving device 53 is located on the left side of the auxiliary mechanism housing 51. The spring piece 524 is used to push the bolt toward the bolt during the extrusion process. C exerts a reaction force so that the bolt C closely fits the threaded locking block 3 when locked, thereby effectively preventing the bolt from loosening and falling off, and the bolt C closely fits the pressure block 536 inside the installation groove 533, increasing the size of the bolt. The force-bearing area at the bottom of C makes bolt C evenly stressed and less likely to deform.
