Service HotlineThe purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a fastener with a new structure with a nut, which cannot be tightened by conventional tools during use, and is suitable for special occasions requiring anti-theft.
The existing way to achieve radial locking of the shaft is generally to sleeve the positioning block on the shaft, and then use a cylindrical pin to pass through the positioning block to lock the shaft. The locking structure and method are as follows: A locking groove with an arc-shaped cross-section is set on the outer side of the shaft along the direction perpendicular to the axis of the shaft, an opening is set on the positioning block, and then a cylindrical pin is used to pass through the positioning block from the outside of the positioning block and screw the lock at one end of the cylindrical pin. When the lock nut is tightened, the opening on the positioning block will be deformed inwardly and locked on the shaft.
In the existing life, repair parts are often used to repair the cassettes with damaged screw holes, and the screw holes on the repair parts are used instead of the original damaged cassette screw holes. However, in the prior art (application number: 201520948368.1), the restoration is fixed by rotating the support of the restoration, which is often inconvenient due to the small space of the cassette. In addition, the set screw in the prior art mainly fastens the object through the end of the screw without threaded holes, which makes it difficult to install external screws. Based on this, a method of extruding the support through a set screw with screw installation holes and tightening the repair piece, and then installing the screw on the set screw, will facilitate the quick installation and use of the repair piece.
kind of screw provided by Yueluo, the rod body of the screw rod has a thread segment, one end of the thread segment is provided with an annular convex ring on the outer peripheral surface of the rod body, and the distance between the convex ring at the front end of the screw threading direction and the rod core Smaller than the nominal size of the threaded section or the distance from the rear end of the bead to the rod core in the screwing direction is greater than the nominal size of the threaded section.
T-bolts are a common type of bolts that tend to be used with rails when used. When the existing rail is in use, the T-shaped bolts are easily stuck and cannot reach the designated position well, and the use is not convenient enough, so that the T-shaped bolts cannot be well fixed.
