Description

Technical Field

[0001] The utility model relates to the technical field of rotary joints, in particular to a self-locking and anti-detachment multi-pipe rotary joint. Background Art

[0002] A multi-line rotary joint is a joint that can transmit multiple media at the same time and has a rotating function. It consists of two inner and outer joints and a rotating part. The rotating part drives the linkage rotation of the inner and outer joints to realize the mutual transmission of multiple media. It is widely used in hydraulics, pneumatics, petrochemicals, papermaking, food and other fields, in which it plays the role of a "connector". However, the current multi-line rotary joint still has the following shortcomings:

[0003] For example, the patent document with application number 202022073964.2 discloses a multi-channel rotary joint. The multi-channel rotary joint has a first main channel and a first secondary channel, a second main channel and a second secondary channel, a third main channel and a third secondary channel, and a fourth main channel and a fourth secondary channel, which are evenly and interlaced at the four corners of the main body and the rotating cylinder. The overall structure greatly reduces the unbalanced force generated when the medium flows. By setting the first secondary channel, the second secondary channel, the third secondary channel and the fourth secondary channel to be parallel to the rotating cylinder, the space used by the utility model is greatly reduced. However, the stability of its connection with the pipeline is poor, and it is not provided with a self-locking structure, which is easy to loosen due to accidental touch.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a self-locking and anti-detachment multi-pipe rotary joint is proposed. Utility Model Content

[0005] The utility model aims to provide a self-locking and anti-dropping multi-pipeline rotary joint to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a self-locking and anti-detachment multi-pipe rotary joint, comprising a joint shell and a connecting assembly, a buffer connecting piece is installed at the right end of the joint shell, the connecting assembly is arranged on the surface of the joint shell, and the connecting assembly includes a fixed joint, a snap-fit ​​connecting cylinder, an inner snap-fit ​​cylinder, a connecting pipe, a fixed cylinder rack, a threaded locking hole and a threaded locking rod, the fixed joint is arranged at the right end of the buffer connecting piece and the left end of the joint shell, and two groups of fixed joints are arranged, a snap-fit ​​connecting cylinder is installed on the surface of the outer end of the fixed joint, and the inner side of the snap-fit ​​connecting cylinder is snap-connected with the inner snap-fit ​​cylinder, the snap-fit ​​connecting cylinder and the inner snap-fit ​​cylinder are both made of steel structures, and the outer end of the inner snap-fit ​​cylinder is connected to the connecting pipe.

[0007] Furthermore, a fixed cartridge rack is installed on the outer surface of the fixed joint, and the fixed cartridge rack is a hard plastic structure.

[0008] Furthermore, the surfaces of the fixed cylinder frame and the engaging connection cylinder are both provided with threaded locking holes, and the inner sides of the threaded locking holes are threadedly connected with threaded locking rods.

[0009] Furthermore, the buffer connector has a hollow structure inside, and a buffer component for buffering water flow is arranged inside the buffer connector.

[0010] Furthermore, the buffer assembly includes a water ring, a connecting rod and a buffer plate, and the water ring is arranged inside the buffer connector close to one end of the joint shell, and a connecting rod is installed on the right surface of the water ring, and a buffer plate is installed inside the buffer connector.

[0011] Furthermore, the buffer assembly also includes a water filter hole and a reset rope, and the water filter hole is opened on the surface of the buffer tray, and the reset rope is connected to the upper and lower ends of the right surface of the buffer tray.

[0012] Furthermore, the reset rope is an elastic rubber structure, and the right end of the reset rope is connected to the right surface inside the buffer connector.

[0013] Furthermore, the joint shell is made of a hard steel structure as a whole, and a fluorocarbon metal coating is provided on the outer surface of the joint shell.

[0014] The utility model provides a self-locking and anti-dropping multi-pipe rotary joint, which has the following beneficial effects:

[0015] 1. The utility model provides a connection assembly, which includes a fixed joint, a snap-fit ​​connection cylinder, an inner snap-fit ​​cylinder, a connection pipe, a fixed cylinder frame, a threaded locking hole and a threaded locking rod. When in use, the connection pipe is connected to the fixed joint through the snap-fit ​​connection between the inner snap-fit ​​cylinder and the snap-fit ​​connection cylinder, and the threaded locking rod is rotated to move the threaded locking rod toward the inner end along the threaded locking hole on the surface of the fixed cylinder frame until it passes through the threaded locking hole on the surface of the snap-fit ​​connection cylinder to further fix the inner snap-fit ​​cylinder, thereby locking the snap-fit ​​connection between the snap-fit ​​connection cylinder and the inner snap-fit ​​cylinder. Disassembly requires unscrewing the threaded locking rod to release the lock, so that the device can lock the connection between the rotary joint and the pipeline, making the connection more stable and less prone to accidental loosening.

[0016] 2. The utility model provides a buffer component, which includes a water ring, a connecting rod and a buffer plate. The buffer component also includes a water filter hole and a reset rope. When in use, after the water inlet at the right end of the water flow buffer connector enters the buffer connector, it will be buffered by the buffer plate and randomly pass through the water filter holes on the surface of the buffer plate. At the same time, the water filter holes can also filter larger impurities to prevent blockage. When the water flows through the water ring, it can be further buffered. If the water filter hole is blocked, the device is disassembled and the buffer plate is pushed inward with a hard strip until the connecting rod pushes out the impurities at the inner end of the water filter hole, so that it can be easily cleaned. After the buffer plate is loosened, the reset rope rebounds to drive the buffer plate to reset, so that the device can prevent the water flow rate from being too fast to cause a large impact on the inside of the joint shell, avoid damage to the inside, and extend its service life.
