A semi hollow six angle screw, including a nut, a screw, and a tapered washer. The nut surface is smooth, and the side is provided with through holes. The upper end of the screw rod is provided with a threaded solid part, and the lower end is a hollow part with a screw thread, wherein the inner part of the hollow part with the thread is a regular hexagon. The conical washer is sheathed on the screw rod and is arranged at the lower end of the nut, and the inner diameter of the tapered washer is slightly larger than the outer diameter of the screw rod. The utility model has the advantages of simple structure, the six angle wrench is inserted into the hollow part at the lower end of the screw, can be used to achieve from the lower end locking screws and disassembly, and can be used for special equipment or inconvenient operation from above conditions, greatly facilitate the work; and the taper washer can meet the installation condition greatly different. To improve the applicability of screws.
【技术实现步骤摘要】
一种半空心内六角螺丝
本技术涉及一种螺丝,尤其是一种半空心内六角螺丝。
技术介绍
螺丝是利用物体的斜面圆形旋转和摩擦力的物理学和数学原理,循序渐进地紧固器物机件的工具。通常都会在螺帽位置设置驱动槽,当需要固定物体时,一端固定螺母,另一端驱动螺母的驱动槽,以此达到固定物体的目的。但是,在特殊机械设备在装卸过程中,有时候一端空间狭窄,给螺丝的装卸带来很大的困难。
技术实现思路
针对上述现有技术的不足,本技术提供了一种结构简单、便于装卸的半空心内六角螺丝。为实现上述目的,本技术采用的技术方案是:一种半空心内六角螺丝,包括螺帽,螺杆和锥形垫圈。其中螺帽表面平滑,侧面设有通孔。螺杆的上端为带有螺纹实心部分,下端为带有螺纹的空心部分,所述带有螺纹的空心部分内壁为正六边形。所述锥形垫圈套在螺杆上并设置在螺帽的下端,锥形垫圈的内径略大于螺杆的外径。优选的,所述的带有螺纹的空心部分内腔深度为7mm,即便与加工又能保证提供足够的拧紧力。优选的,所述正六边形的边长为5mm。本技术结构简单,通过将外六角扳手插入到螺杆下端的空心部分内,可以用来实现从下端对螺丝进行锁紧和拆卸,也可以通过螺帽侧面的通 ...
