AI Technical Summary
The joints of existing high-pressure water-cleaning pipes have low pressure bearing strength, which leads to explosive pipes when bending under high pressure conditions, and is inconvenient to operate, affecting service life.
A rotary joint is designed, adopting an arc-shaped connecting rod and shell structure, and the circular movement of the shell is realized through the left-hand ring and the sealing gasket, dispersing the stress during the connection of high-pressure pipes, and providing a rotary connection method.
It improves the pressure bearing capacity of the joint, extends the service life, enhances the convenience of operation and connection stability, and avoids the risk of pipe bursting.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-pressure fluid delivery pipeline accessories, in particular to a rotary joint. Background Art
[0002] With the rapid development of my country's economy, the industrial cleaning industry, as an important part of China's industrial economy, has also been booming. Data show that in 2011, the market for industrial cleaning equipment and industrial cleaning agents in China alone will reach 20 billion yuan. Industrial cleaning is the process of removing these pollutants or covering layers to restore the original surface condition of objects by physical, chemical or biological effects. With the acceleration of my country's reform and opening up and modernization construction, as well as the strengthening of people's awareness of environmental protection, high-pressure water jet cleaning technology has fast cleaning speed, good cleaning effect and no secondary pollution after cleaning, and is accepted by more and more companies. At present, the joints used in domestic high-pressure water cleaning pipes are fixedly connected, and the pressure-bearing strength is low. Because the high-pressure pipe cannot be bent in high-pressure water cleaning, the stress on the joint body is relatively large. After the high-pressure pipe is bent, it is very easy to burst and cause personal injury, and the operation is inconvenient. Utility Model Content
[0003] The utility model provides a rotary joint to solve the problem in the prior art that stress concentration in connection with a high-pressure pipeline affects the service life of the joint.
[0004] The technical solution adopted by the utility model to solve its technical problems is:
[0005] A rotary joint comprises a connecting rod, a nut and a shell. The connecting rod has an arc-shaped tube structure. An external thread is arranged at the end of the connecting rod. The shell is threadedly connected to the nut on the surface of the end of the connecting rod. A sealing gasket and a left-handed ring are arranged between the nut and the connecting rod. A retaining ring is arranged on the left-handed ring.
[0006] When the rotary joint of the utility model is used, the high-pressure pipe is connected to the external thread of the end of the connecting rod. During the high-pressure pipe connection process, the shell can perform a circular motion on the surface of the nut through the left-handed ring, and the stress generated during the high-pressure pipe connection process is relieved through the circular motion of the shell.
[0007] The utility model connector has a rotating connection structure between the shell and the connecting rod. The shell can move axially and circularly through the left-handed ring, thereby relieving the stress generated during the high-pressure pipe connection process. It has the advantages of simple structure, convenient use and firm connection. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0009] Figure 1It is a structural schematic diagram of the utility model.
[0010] In the figure, 1 is a connecting rod, 2 is a nut, 3 is a housing, 4 is a sealing gasket, 5 is a left-handed ring, and 6 is a retaining ring. DETAILED DESCRIPTION
[0011] As shown in the figure, a rotary joint includes a connecting rod 1, a nut 2 and a shell 3. The connecting rod 1 has an arc-shaped tube structure, an external thread is arranged at the end of the connecting rod 1, the shell 3 is threadedly connected to the nut 2 on the end surface of the connecting rod 1, a sealing gasket 4 and a left-handed ring 5 are arranged between the nut 2 and the connecting rod 1, and a retaining ring 6 is arranged on the left-handed ring 5.
[0012] When the rotary joint of the utility model is used, the high-pressure pipe is connected to the external thread of the end of the connecting rod. During the high-pressure pipe connection process, the shell can perform a circular motion on the surface of the nut through the left-handed ring, and the stress generated during the high-pressure pipe connection process is relieved through the circular motion of the shell.
