Problems solved by technology

[0003] However, during the installation and use of the generator, the existing bolts have certain requirements for water resistance and airtightness due to the fact that they contain a variety of intelligent components inside. However, the airtightness and water resistance of traditional intelligent bolts In addition, in a high temperature environment, due to the thermal expansion and contraction of many mechanisms inside the device, the strain induction is deviated

Embodiment Construction

[0020] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0021] Such as Figure 1-Figure 4 As shown, a bolt according to the present invention includes a main body mechanism 1, a fixing mechanism 2, a strain mechanism 3, a temperature compensation mechanism 4 and a sealing mechanism 5, and is used for the side wall of the main body mechanism 1 that is threadedly connected with other devices. The top is fixedly installed with the fixing mechanism 2 for fixing electrical connection wires, the inside of the main body mechanism 1 is provided with the strain mechanism 3 for detecting stress changes, and the inside of the top of the main body mechanism 1 is fixedly arranged for The temperature compensating mechanism 4 for temperature compensation of the strain mechanism 3 , and the sealing mechanism 5 for pro...

Abstract

The invention relates to the field of bolts, in particular to a bolt. The bolt comprises a main body mechanism, a fixing mechanism, a strain mechanism, a temperature compensation mechanism and a sealing mechanism. When a high-temperature environment is met, a strain gauge is heated to expand due to thermal expansion and cold contraction, so that a use process is influenced, at the moment, two first air bags are heated to expand, two abutting blocks are pushed correspondingly, the two abutting blocks push two springs correspondingly, namely the two springs push two push plates correspondingly,then the two push plates push the strain gauge, the strain gauge is extruded, namely the shape change of the strain gauge caused by the thermal expansion and cold contraction can be compensated and recovered, so that when the device is used in a high-temperature state, the change of the strain gauge caused by the influence of environment can be compensated, the device can ensure the accuracy of the pressure induction of the strain gauge in the high-temperature environment in actual use.

Description

technical field [0001] The invention relates to the field of bolts, in particular to a bolt. Background technique [0002] Bolts are cylindrical threaded fasteners that mate with nuts. A type of fastener consisting of a head and a screw, which needs to be matched with a nut to fasten two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. [0003] However, during the installation and use of the generator, the existing bolts have certain requirements for water resistance and airtightness due to the fact that they contain a variety of intelligent components inside. However, the airtightness and water resistance of traditional intelligent bolts In addition, in a high temperature environment, due to thermal expansion and contraction of many mechanisms inside the device, the strain induction is deviated.
