Embodiment Construction

[0010] The present invention is described in detail with reference to the accompanying drawings as follows:

[0011] The invention essentially consists of the following components: the nut (10) has a flange (11) on one end face of its generally cylindrical body, the rotation of the flange 11 of the nut (10) relative to its axis being subject to The limitation of one of the components to be clamped (the first component) (MI), the inner peripheral surface of the nut (10) is made with a first thread (13) (right-handed internal thread made on the center hole of the flange) ) and a second thread (14) (left-handed internal thread and made on the inner side wall into which the bolt described later is inserted); the movable sleeve (20) has a second thread (14) that can be screwed into the nut and is An external thread (left-handed thread, the portion formed with the external thread refers to the lower first thread (21)) made on the outer peripheral surface of its substantially cylindr...

Abstract

A fastener for members (M1, M2) to be clamped with a certain spacing therebetween includes a nut (10); a bolt (40); and a moveable collar (20) having in an inner bore thereof a torque transmitting device capable of transmitting torque of the bolt, which is axially inserted into the inner bore, to the movable collar through thread-thread engagement, and wherein a portion of the thread of the bolt includes special thread ridges (422), by which a frictional force is imparted to the thread-thread engagement.

Description

technical field [0001] The invention relates to a fastening device capable of clamping elements. The clamping elements need to be spaced apart from each other at a certain distance. While maintaining a certain gap between the elements, it can absorb some possible dissipation or some possible shafts in the interval. towards deviation. Background technique [0002] US Patent No. 5,288,191 to Eduald Rucker et al. discloses a common fastening device of the same type as described above, which is composed of many components, some of which are specially shaped and therefore expensive to manufacture. In addition, the force required to move the constituent element because of the adjustment of the predetermined space depends on the thrust and torque to insert the bolt-like member into the constituent element against the frictional force. The operator clamps the fastener to apply a thrust to turn the bolt-like element. Therefore, the operation of the fastening device is complicated. ...
