Description

Technical Field

[0001] The utility model relates to the technical field of pipe joints, in particular to a pipe joint with an anti-loosening structure. Background Art

[0002] Pipe fittings are connecting tools between pipes, detachable connection points between components and pipes, parts for connecting pipes in hydraulic systems or installing pipes on hydraulic components, and also connectors that can be installed and removed in fluid pathways. Therefore, pipe fittings play an indispensable and important role in pipe fittings. They are one of the two main components of hydraulic pipelines. Since pipe fittings are detachable connecting elements, in addition to meeting the normal requirements of stable connection, strong sealing, reasonable size, small pressure loss, good process performance, etc., they must also meet the requirements of convenient disassembly and assembly. Traditional pipe fittings rely entirely on the threaded connection between the outer sleeve nut and the pipe fitting. During use, especially under complex working conditions such as vibration, the threads are prone to loosening, resulting in oil leakage. Utility Model Content

[0003] The purpose of the utility model is to provide a pipe joint with an anti-loosening structure in view of the shortcomings of the prior art, so as to solve the problem that the traditional pipe joint proposed in the above background technology completely relies on the threaded connection between the outer sleeve nut and the pipe joint. During use, especially under complex working conditions such as vibration, the thread is easy to loosen, resulting in oil leakage.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pipe joint with an anti-loosening structure, comprising a pipe joint structure, one end of which is provided with a connecting pipe structure;

[0005] The pipe joint structure comprises a pipe joint body with a first thread on the inner side, a connecting plate with a mounting groove is fixed inside the pipe joint body, and a magnet block is fixed to the connecting plate through the mounting groove;

[0006] The outer wall of the pipe joint body is provided with a second thread, and a mounting ring with a first locking tooth is fixed to the outer ring of the pipe joint body.

[0007] By adopting the above technical solution, the arranged magnet block can be used for adsorption and fixing.

[0008] Preferably, the connecting pipe structure includes a sleeve having a threaded pipe fixed at one end, and a mounting plate matched with the connecting plate is fixed at one end of the threaded pipe.

[0009] By adopting the above technical solution, the provided installation plate can achieve supporting adsorption installation.

[0010] Preferably, a through-hole nut is rotatably mounted on the surface of the sleeve via a connecting bearing, and a connecting seat is welded and fixed on the through-hole nut, and a through-hole plate with a threaded barrel is welded and fixed on the connecting seat.

[0011] By adopting the above technical solution, through the setting.

[0012] Preferably, a handwheel threaded rod is provided inside the threaded barrel, and a wrapping cover is fixed to the bottom of the handwheel threaded rod through a bearing seat.

[0013] By adopting the above technical solution, the wrapping cover is provided to achieve wrapping adjustment.

[0014] Preferably, a connecting ring is provided through the threaded tube, and a second locking tooth is fixed on one side of the connecting ring.

[0015] By adopting the above technical solution, the threaded pipe is provided to achieve threaded matching connection.

[0016] Preferably, the connecting seats are provided in one group, and the connecting seats are symmetrically arranged about the axis of the through hole nut.

[0017] By adopting the above technical solution, a fixed connection is achieved through the provided connecting seat.

[0018] Compared with the prior art, the utility model has the beneficial effects that: the pipe joint with the anti-loosening structure,

[0019] (1) This case solves the problem that the traditional pipe joint completely relies on the threaded connection between the outer sleeve nut and the pipe joint. During use, especially under complex working conditions such as vibration, the thread is easy to loosen, resulting in oil leakage. After the threaded pipe and the sleeve are installed and connected to the pipe joint body, the threaded pipe is matched with the first thread and the magnet block for adsorption connection. Then, the through-hole nut and the second thread are threadedly connected and fixed to the pipe joint body so that the first clamping tooth, the installation ring, the connecting ring and the second clamping tooth are relatively squeezed and locked. When the first clamping tooth and the second clamping tooth are relatively meshed and locked, the through-hole nut is prevented from being easily loosened due to force, resulting in the sleeve and the threaded pipe being separated from the pipe joint body;

[0020] (2) The connecting pipe structure is provided with: a connecting seat, a threaded barrel, a through-hole plate, a handwheel threaded rod and a wrapping cover, so as to solve the problem that the pipe is pulled by external force, causing the pipe to be bent at different angles at the pipe joint, thereby causing leakage. When the handwheel threaded rod is turned, the wrapping cover is driven to move under force through the bearing seat. When the pipe is connected through the wrapping cover, one end of the pipe is always connected to the connection position of the pipe joint body in a straight connection state, thereby avoiding the connection position being bent under force and causing leakage.
