Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipe joint locking, in particular to a pipe joint locking gasket. Background Art
[0002] During the production and construction of low-speed marine diesel engines, small-diameter pipes are typically connected using pipe joints. When these joints become loose, the seal is compromised, leading to problems such as liquid leakage. A common solution is to use a locking nut. However, these nuts are inconvenient to remove after installation and are disposable, increasing the cost of fixing the pipe joints. Therefore, those skilled in the art have developed a pipe joint locking washer to address the issues raised in the background art. Utility Model Content
[0003] (1) Technical problems solved
[0004] In view of the deficiencies of the existing technology, the utility model provides a pipe joint locking gasket to solve the problem that the method of fixing the pipe joint with a locking nut is inconvenient to disassemble after installation, is a disposable accessory, and increases the fixing cost of the pipe joint.
[0005] (2) Technical solution
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a pipe joint locking gasket, comprising a pipe joint body and a locking gasket, wherein one end of the locking gasket is provided with a tooth groove, and the other end of the locking gasket is provided with a threaded hole, and a bolt is threadedly connected to the threaded hole.
[0007] Preferably, the locking washer is Z-shaped, and one end of the locking washer with a tooth groove is clamped with the pipe joint body, and the end of the locking washer with a threaded hole is folded and fits with the side wall of the bolt end, thereby squeezing and limiting the bolt to prevent the bolt from loosening, thereby achieving the effect of tightening the pipe joint body.
[0008] Preferably, a positioning bolt is installed on the upper side of the end of the locking washer with the tooth groove, and an elastic plate is provided on one side of the positioning bolt. Both ends of the elastic plate are installed with hanging ears, and the hanging ears are clamped with the positioning bolt. The inner side of the elastic plate is pressed and contacted with the side wall of the pipe joint body. The elastic plate can fit and squeeze the side of the pipe joint away from the tooth groove, so that the end of the locking washer with the tooth groove can be firmly connected to the pipe joint body, avoiding the problem of the tooth groove being detached from the pipe joint due to deformation of the locking washer.
[0009] (3) Beneficial effects
[0010] Compared with the prior art, the present invention provides a pipe joint locking gasket with the following beneficial effects:
[0011] Through design, the end of the locking washer with the tooth groove is plugged into the hexagonal part on the pipe joint body, and then the locking washer is fixed by a bolt. After the locking washer is fixed with the bolt, the end of the locking washer adjacent to the bolt is folded up so that the folded end of the locking washer fits with the hexagonal end of the bolt, thereby squeezing and limiting the bolt to prevent the bolt from loosening, thereby achieving the effect of tightening the pipe joint body. In addition, this structure is easy to disassemble and can be reused, reducing the fixing cost of the pipe joint. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0017] The utility model provides a technical solution, a pipe joint locking gasket, please refer to Figure 1 、 Figure 3 , including a pipe joint body 1 and a locking washer 2, one end of the locking washer 2 is provided with a tooth groove 201, and the other end of the locking washer 2 is provided with a threaded hole 202, and the threaded hole 202 is internally threaded with a bolt 3, the locking washer 2 is Z-shaped, and the end of the locking washer 2 with the tooth groove 201 is clamped with the pipe joint body 1, and the end of the locking washer 2 with the threaded hole 202 is folded and fits against the side wall of the end of the bolt 3, thereby squeezing and limiting the bolt 3 to prevent the bolt 3 from loosening, thereby achieving the effect of tightening the pipe joint body 1.
[0018] See also Figure 2 、 Figure 3A positioning bolt 4 is installed on the upper side of one end of the locking washer 2 with a tooth groove 201, and an elastic plate 5 is provided on one side of the positioning bolt 4. Lugs 501 are installed at both ends of the elastic plate 5, and the lugs 501 are clamped with the positioning bolt 4. The inner side of the elastic plate 5 is pressed and contacted with the side wall of the pipe joint body 1.
