Description

Technical Field

[0001] The utility model relates to the field of connecting pipe connectors, and more specifically, to an anti - detachment joint for a bent connecting pipe. Background Art

[0002] The bent pipe is bent by using a complete set of bending equipment, which is divided into two processes: cold bending and hot pushing. No matter which kind of machinery and equipment and pipelines, most of them use bent pipes, which are mainly used for oil transportation, gas transportation, liquid transportation, engineering bridge construction, etc. When two pipe bodies are spliced, a connecting joint is required.

[0003] Some existing connectors are connected by screwing. When the connector is used multiple times, the phenomenon of thread slipping may occur. When the pipeline transports the medium, the connector may fall off under the impact force of the transported medium, reducing the connection effect of the connector and possibly causing waste of some materials. Therefore, in order to solve the above problems, we propose an anti - detachment joint for a bent connecting pipe. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides an anti - detachment joint for a bent connecting pipe, and adopts the following technical solutions:

[0005] An anti - detachment joint for a bent connecting pipe includes a joint body. Both ends of the joint body are provided with assembling pipes. A plurality of fastening blocks distributed in an annular array are arranged on the side of the assembling pipe away from the joint body. Nuts are arranged on the side walls of the same - group fastening blocks and the assembling pipes. Threaded teeth matching the nuts are opened on the side walls of the same - group fastening blocks and the assembling pipes. Rotating rings are fixedly sleeved on the side walls of both nuts. Fixing components are arranged between the opposite end side walls of the two assembling pipes and the joint body. Stabilizing components are arranged between the opposite ends of the two rotating rings and the joint body.

[0006] When the device is used, the staff sleeved the assembling pipe and the nut on the side wall of the pipe body of the existing technology, and then adjusted the position of the assembling pipe on the side wall of the pipe body. Subsequently, through the screwing of the nut with the threaded teeth opened on the side walls of the fastening block and the assembling pipe, the cooperation of the fastening block and the nut can play a role in fixing the assembling pipe. Then, the staff docked one end of the joint body with one side of the pipe body, and then the joint body and the pipe body can be fixed through the fixing component. A stabilizing component is arranged on the side wall of the joint body. Through the cooperation of the stabilizing component and the rotating ring installed on the side wall of the nut, the nut can be restricted and positioned, which helps to avoid the loosening of the nut, and thus is beneficial to maintaining the stability of the assembly of the joint body and the pipe body.

[0031] Please refer to Figures 1-5, a detachable joint for a bent connecting pipe, comprising a joint body 1. Both ends of the joint body 1 are provided with assembled pipes 7. On the side of the assembled pipes 7 away from the joint body 1, a plurality of fastening blocks 14 are arranged in an annular array. For the same group of fastening blocks 14 and the side wall of the assembled pipe 7, nuts 6 are provided. Threaded teeth matching the nuts 6 are provided on the side walls of the same group of fastening blocks 14 and the assembled pipe 7. Rotating rings 5 are fixedly sleeved on the side walls of both nuts 6. Inside both ends of the joint body 1, inserting pipes 13 are fixedly installed, and one end of both inserting pipes 13 close to the same-side nut 6 extends out of the joint body 1. A plurality of sealing rings are arranged on the side walls of both inserting pipes 13 in a linear array. Anti-slip pads are fixedly sleeved on the side walls of both inserting pipes 13 close to one end of the joint body 1. Rubber pads are fixedly installed on the inner walls of the assembled pipes 7 and the inner walls of the fastening blocks 14. When the device is in use, the staff sleeved the assembled pipes 7 and the nuts 6 on the side wall of the pipe body in the prior art. Subsequently, the position of the assembled pipe 7 on the side wall of the pipe body is adjusted. Then, through the screwing of the nut 6 with the threaded teeth provided on the side walls of the fastening block 14 and the assembled pipe 7, through the cooperation of the fastening block 14 and the nut 6, the assembled pipe 7 can be fixed. Moreover, due to the rubber pads provided on the inner walls of the assembled pipe 7 and the fastening block 14, it is beneficial to increase the friction force between the assembled pipe 7, the fastening block 14 and the pipe body, and thus it is beneficial to maintain the stability of the installation of the assembled pipe 7.

[0032] Between the side walls of the opposite ends of the two assembled pipes 7 and the joint body 1, fixing components are provided. The fixing components include two first support plates 9 fixedly installed at one end of the assembled pipe 7 close to the joint body 1. The two first support plates 9 are symmetrically distributed on the side wall of the same group of assembled pipes 7. On both side walls of the joint body 1, two symmetrically distributed second support plates 10 are fixedly installed. Between the same group of first support plates 9 and second support plates 10, they are fixed through bolts 8 and nuts 11. After the assembled pipe 7 is installed, the staff places the inserting pipe 13 installed at the end of the joint body 1 inside the pipe body. And the side wall of the inserting pipe 13 is provided with a sealing ring and an anti-slip pad, which is beneficial to increase the friction force between the inserting pipe 13 and the inner wall of the pipe body, and thus it is beneficial to maintain the stability of the assembly of the pipe body and the joint body 1. Then, the first support plates 9 and the second support plates 10 are aligned. Then, through the cooperation of the bolts 8 and the nuts 11, the joint body 1 and the pipe body can be fixed.

[0033] A stabilizing component is provided between each of the two rotating rings 5 and the opposite ends of the joint body 1. The stabilizing component includes struts 2 hinged to the side walls at both ends of the joint body 1. There are two struts 2 in the same group and they are symmetrically distributed on the side wall of the joint body 1. In the same group, both of the two struts 2 are provided with movable grooves 15 near the side of the assembled pipe 7 on the same side. A support rod 3 is slidably installed in each of the movable grooves 15. Between one end of the support rod 3 and the inner wall of the opposite side of the movable groove 15 on the same side, two symmetrically distributed springs 16 are fixedly connected. At the end of the support rod 3 far from the springs 16 on the same side, mounting plates 4 are fixedly installed. The cross sections of the mounting plates 4 are all in an inverted "L" shape.
