Service Hotlineflange T-bolt, comprising: a T-bolt including a threaded tooth body and a bolt head fixedly connected to the threaded tooth body; a flange gasket with a plurality of clip teeth, the flange gasket passing through the The plurality of clamping teeth are clamped with the bolt head of the T-bolt. The technical solution of the utility model is that when the groove-type embedded parts are embedded vertically or at a certain angle, the plastic flange of the new T-bolt will help the bolt to be pre-positioned at a certain position of the groove. When multiple T-bolts are used for fixing, Only one worker needs to pre-arrange the bolt positions and then lock the nuts, which greatly improves the construction efficiency.

Washers are common parts that are annular or annular after compression. The existing standard washers include flat washers, spring washers, serrated lock washers, saddle washers, etc. The end faces are mostly flat or flat after compression. , so it is in surface contact with the workpiece. Generally, after the two workpieces are locked by washers, bolts and nuts, the workpieces cannot move in any direction, so as to achieve the purpose of tightening the two workpieces. In actual production, some workpieces are still required to be properly translated in a certain direction after locking. In order to achieve this requirement, the usual practice is to open a waist-shaped hole on the workpiece that needs to be moved, and the zigzag-shaped bushing is fitted with a flat washer after passing through the waist-shaped hole, as shown in FIG. The edge of the hole is located in the space enclosed by the bushing and the flat washer, and a gap is formed between the workpiece and the bushing and the flat washer, so that even if the bolt passes through the flat washer, the bushing and the workpiece in turn, it is threaded and locked with the nut. tight, the workpiece can still translate along the length of its girdle hole. Obviously, this method can achieve the requirement of proper translation of the workpiece, but the following deficiencies can still be found in the actual assembly. First, before locking, the bushing, washer and workpiece are separated from each other, so it is more inconvenient to assemble; secondly, the lining is The separation structure of the sleeve and the gasket is inconvenient to manage, and the disassembled gasket and bushing are easy to lose and affect the use again.
In view of the above problems, Guangdong Yueluo Hardware Industry Co., Ltd. aims to provide a new type of open blind rivet suitable for riveting of aluminum, steel and stainless steel sheets with foamed materials.
In each maintenance, the newly replaced stud bolts and other accessories should be inspected. During the inspection, the focus should be on the head and guide part of the stud bolt. It is also necessary to strictly check that each part of the thread has No cracks or dents, also check the tooth shape of the studs for changes. Is there any abnormality in the thread pitch? If there is any abnormality, it must not be used again. A torque wrench should be used when installing the connecting rod cover. It must be tightened according to the specified standards, the torque should not be too large or too small, and attention should be paid to selecting the stud bolts and studs of the supporting manufacturer.
