Description

Technical Field

[0001] This utility model belongs to the field of engineering monitoring technology, specifically relating to a deformation monitoring point device with a two-level anti-loosening structure. Background Technology

[0002] Chinese patent CN 218153357 U discloses a deformation monitoring point device. However, conventional bolted connections are prone to loosening under continuous vibration, causing prism position displacement. Furthermore, the connection between the prism rod and the bolt lacks an effective anti-loosening structure, leading to intermittent errors in monitoring data after long-term use. Existing anti-loosening measures primarily rely on periodic manual tightening, which cannot achieve continuous and stable monitoring.

[0003] Therefore, this utility model proposes a deformation monitoring point device with a two-stage anti-loosening structure to solve the above problems. Utility Model Content

[0008] The top surface of the anti-loosening nut is serrated, and the serrations on the top surface of the anti-loosening nut engage with the bottom surface of the hexagonal flange nut;

[0009] The anti-loosening nut is welded to the top of the prism rod, and the inner wall of the prism rod is provided with an embedded thread. The embedded thread of the prism rod forms a threaded connection with the anti-loosening bolt.

[0010] The aforementioned deformation monitoring point device with a two-stage anti-loosening structure is characterized in that: the anti-loosening bolt is a galvanized bolt, and the anti-loosening nut is a galvanized nut.

[0011] The aforementioned deformation monitoring point device with a two-stage anti-loosening structure is characterized in that: the prism rod is a stainless steel prism rod.

[0023] like Figures 1 to 4 As shown, this utility model includes a deformation monitoring point device with a two-stage anti-loosening structure, including a prism lens, an anti-loosening nut 4 and a prism rod 5. The prism lens is composed of a prism 1 welded to an anti-loosening bolt 2. The anti-loosening bolt 2 is also fitted with a hexagonal flange nut 3. The bottom surface of the hexagonal flange nut 3 is serrated. The hexagonal flange nut 3 is threadedly connected to the anti-loosening bolt 2.

[0024] The top surface of the anti-loosening nut 4 is serrated, and the serrations on the top surface of the anti-loosening nut 4 mesh with the serrations on the bottom surface of the hexagonal flange nut 3;

[0025] The top of the prism rod 5 is welded with an anti-loosening nut 4, and the inner wall of the prism rod 5 is provided with an embedded thread. The embedded thread of the prism rod 5 forms a threaded connection with the anti-loosening bolt 2.

[0029] It should be noted that the stainless steel material is rust-resistant and suitable for complex environments such as underground monitoring. The prism rod surface has anti-slip grooves to increase the friction when the device is buried underground, for stability.

[0030] In actual use, the anti-loosening bolt 2 on the prism is screwed into the internal thread on the inner wall of the prism rod 4 to form a threaded connection. At the same time, the serrated top surface of the anti-loosening nut 3 engages with the bottom surface of the hexagonal flange nut on the anti-loosening bolt 2.

[0031] This utility model forms a two-stage anti-loosening structure through the above design: the bottom serrations of the hexagonal flange nut 3 on the anti-loosening bolt 2 engage with the top serrations of the anti-loosening nut 4 to form the first-stage anti-loosening structure; the embedded thread of the prism rod 4 is connected to the thread of the anti-loosening bolt 2 to form the second-stage anti-loosening structure.

[0032] In summary, this utility model has a simple structure and is easy to install.
