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, specifically a bolt, including a main body mechanism, a fixing mechanism, a strain mechanism, a temperature compensation mechanism and a sealing mechanism; when encountering a high temperature environment, due to thermal expansion and contraction, the strain gauge is heated and expanded , which affects the use process; at this time, the two first airbags are heated and expanded to push the two abutting blocks respectively, and the two abutting blocks respectively push the two springs, and the two abutting blocks respectively push the two springs. The springs respectively push the two push plates, and then the two push plates push the strain gauges, so that the strain gauges are squeezed, and the strain gauges are deformed due to thermal expansion It can be compensated and restored, so that when the device is used in a high temperature state, it can compensate the change of the strain gauge caused by the influence of the environment, so that the device can ensure the pressure sensing performance of the strain gauge in a high temperature environment in actual use. precise.

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.
