Abstract

The invention relates to a thread connecting device convenient to operate, a thread connecting structure convenient to operate and a pre-tightening method of the thread connecting structure convenientto operate. The thread connecting device includes an upper and a lower wedge of the trapezoidal prism structure. The inclined surfaces of the upper and lower wedges are attached with each other, thethicker end of the lower wedge is on the same side as the less thicker end of the upper wedge, the less thicker end of the lower wedge is on the same side as the thicker end of the upper wedge,. slotsare arranged in the upper and the lower wedges, a fixing bolt passes through the slots, the cap of the fixing bolt and the lower wedge are correspondingly arranged on both sides of the upper wedge, the relative motion of the upper wedge and the lower wedge will drive the fixing bolt to move in the axial direction, the lower wedge is connected with a lever mechanism, and the lever mechanism can drive the upper wedge and the lower wedge to produce relative motion. The structure is simple, using is convenient, and the disassembly speed of bolts between connecting units can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of threaded fasteners, in particular to a conveniently operated threaded connection device, a connection structure and a pretightening method thereof. Background technique [0002] Threaded connections play an important role in the production and processing of products. When processing products of different specifications, it is often necessary to adjust the processing equipment, replace different modules or different types of molds, and frequently disassemble bolts and nuts. Speed ​​puts new demands on it. Now, when replacing bolted parts, it is necessary to use different types of wrenches to tighten or loosen the bolt rotation. It is not suitable for disassembling the bolts in the narrow and long working area. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, provide a conveniently operated threaded connection devic...
