The anti-loosening structure of the screw sleeve on the plug head of the pressing rod

Abstract

The invention relates to an anti-loosening structure for a press bar chock plug additionally-arranged thread sleeve. The anti-loosening structure comprises a press bar assembly and a clamping base assembly. The press bar assembly comprises a press bar, a press bar chock plug, a press bar chock plug plunger, a spring, the thread sleeve and a bolt. The press bar is provided with a cylinder barrel and a solid cylinder boss which are integrally formed. The press bar chock plug plunger is provided with a first sleeve and a second sleeve which are arranged in an inverted-T shape. The press bar chock plug plunger is inserted in an inner cavity of the cylinder barrel. The press bar chock plug is inserted in an inner cavity of the first sleeve and is connected with a thread in a matched manner, and loosening of the press bar chock plug is prevented. The thread sleeve is contained in an inner cavity of the second sleeve and connected with the thread in a matched manner. The press bar chock plug is provided with a through hole. The bolt penetrates the through hole, is inserted in the thread sleeve, and is connected with an inner thread of the thread sleeve in a matched manner. Connection of the press bar chock plug and the press bar is further strengthened, the effect of loosening preventing of the press bar chock plug is achieved, and the using fastness and reliability of the component are guaranteed.

Description

technical field [0001] The invention relates to the technical field of threaded connection of machine equipment parts, in particular to an anti-loosening structure in which a screw sleeve is added to a plug head of a pressing rod. Background technique [0002] Every piece of machinery and equipment is assembled from various parts, and whether the connection of each part is firm is the core of the machinery and equipment. When the components in the machine equipment are connected by screw sleeves, the screw sleeves are prone to rotate by themselves during the process of screwing in the bolts. The screw sleeves have never been unable to fasten the connected parts and affect the reliability of the equipment. At present, when the machine equipment is used for a period of time, the connection of some parts will be loose, which will affect the normal operation of the machine, and the service life of the machine equipment will also be reduced accordingly, which will also cause prod...

AI Technical Summary

Problems solved by technology

[0003] The existing anti-loosening screw sleeve of the pressure rod plug only plays a role in fastening and preventing loosening of the pressure rod plug according to the structure of the internal and external threads of the screw sleeve. The external thread of the screw sleeve is left-handed and the internal thread is right-handed. The rod is locked and reinforced to the plug head of the pressure rod, and the screw sleeve is connected to the pressure rod through the thread of the external thread; the internal thread of the screw sleeve is not connected to the bolt of the plug head of the pressure rod, and the screw sleeve of the plug head of the pressure rod is locked after a period of time In use, the thread teeth of the screw sleeve are worn out, and the internal and external threads of the screw sleeve will loosen the fastening of the plug head of the pressure rod, the service life of the machine and equipment will be reduced, and the production efficiency will also be reduced accordingly.
