Problems solved by technology

When used for a long time or subjected to external force, it is easy to loosen
After the screw and nut are loose, it is difficult to judge with the naked eye, so they are often ignored, causing equipment damage or affecting the fastening effect, and even causing safety accidents
[0003] The existing device for indicating screw loosening can only indicate the loosening of the screw, and cannot indicate the loosening of the nut at the same time, so when the nut is loose, it is impossible to know, and it will also cause damage to the equipment or cause a safety accident

Embodiment Construction

[0010] As shown in the figure, a screw pointer 1.2 is installed at one end of the screw rod 1 through a pin 1.1, and a position adjustment plate 2.0 with a nut pointer 2.2 is installed at the front side of the nut 2 through an adjusting screw 2.1. The nut is installed on the screw rod.

[0011] Use of the invention:

[0012] When the structural parts are fastened by the screw and the nut, when the nut is tightened on the screw, loosen the pin, manually point the screw pointer to the vertical position up or down, and then loosen the adjusting screw on the position adjustment plate, so that the nut pointer is in line with the vertical position The screw pointer coincides, and then the position adjustment plate is fixed.

[0013] When the screw or nut is loose, the screw pointer and the nut pointer deviate from the angle. When the deviation occurs, it means that the screw or nut is loose. It is necessary to continue to tighten the nut to ensure that the screw and nut are in a ti...

Abstract

The invention provides a screw rod and nut loose state indicating device. A screw rod pointer is arranged at one end of a screw rod through a dowel; a positioning adjusting plate with a nut pointer is arranged on the front side of a nut through an adjusting screw. Due to the fact that the screw rod pointer and the nut pointer are simultaneously arranged on the screw rod and the nut, the loose states of the screw rod and the nut can be simultaneously indicated. The screw rod and nut loose state indicating device is suitable for being used as an iron tower screw rod and nut loose state indicating device in the field of electric power.

Description

technical field [0001] The invention provides an appliance in the field of electric power, in particular a screw and nut loose state indicating device. Background technique [0002] In the field of power engineering, especially iron towers, screws and nuts are often used for assembly and fastening of components. When used for a long time or subjected to external force, it is easy to loosen. After the screw and nut are loose, it is difficult to judge with the naked eye, so they are often ignored, causing equipment damage or affecting the fastening effect, and even causing safety accidents. [0003] The existing device for indicating screw loosening can only indicate the loosening of the screw, but cannot indicate the loosening of the nut at the same time. Therefore, when the nut is loose, it is impossible to know, and it will also cause damage to the equipment or produce a safety accident. Contents of the invention [0004] In order to simultaneously indicate the loose s...
