The utility model provides a thread sleeve locking button, it is with the screw thread of the screw sleeve body and 4 locking keys. The connecting part of the threaded sleeve body comprises an integrally formed and the locking part, external thread is arranged on the connecting part, through the internal thread connecting part and a locking part; the locking part is arranged on the outer circumference of the axial 4 evenly distributed dovetail keyway, the dovetail groove is inserted in the locking button; the outer circumference direction connecting part and the locking part in the middle of which is provided with slot. The utility model is integrally molded, and a stepped shaft shaped, easy to realize the strength of the screw sleeve, and to limit and installation, when screwed into the external screw thread hole, the screw sleeve through the shaft shoulder lock of positioning, because the lock key is inserted into the dovetail groove after the locking part along the radial depth the high degree is greater than radial dovetail keyway, so the locking key is inserted into the dovetail keyway within the locking part to achieve screw sleeve fixed in the circumferential direction, so as to ensure the reliable connection of the screw sleeve and the matrix.
【技术实现步骤摘要】
一种带锁紧键的螺套
本技术涉属于机械制造领域,具体地说是涉及一种带锁紧键的螺套。
技术介绍
螺套是为保护有色金属螺纹孔而发展的嵌入物,适用于螺纹连接,旋入并紧固在被连接件之一的螺纹孔中,形成标准内螺纹。螺套具有较高的硬度及较好的表面粗糙度,常应用于需高强度内螺纹的环境,抗震、抗拉拔能力强。装于螺孔或螺母中,有减轻螺纹牙受力不均和抗冲击振动的作用,可以提高螺纹的疲劳强度,减少螺纹的磨损和抗腐蚀性能,并能分散应力保护基体螺纹,大大延长基体的使用寿命。另外,螺套还可以在原基体上的螺纹脱扣或乱牙时,作为修复手段,而不致造成整个基体报废,并且维修方便,快速经济。普通型螺套由于没有自锁能力,容易松动、脱落,且在力矩较大时,螺套常常与螺钉一起转动,从而导致螺套从零件基体螺纹孔中脱落出来,造成零件基体螺纹孔的损坏,给维修带来很大的麻烦,甚至导致更换零件基体。所以,急需一种自锁的螺套,既能够保证螺纹的强度,又不容易松动、脱落,使连接更加牢固。
技术实现思路
为克服上述缺陷,本技术的目的是提供一种带锁紧键的螺套,通过螺套连接部与锁紧部之间的紧密配合来实现螺套的锁紧,从而避免螺套的松动与脱落。 ...
