Pipeline joint structure

Abstract

The invention relates to a pipeline joint structure. The pipeline joint structure comprises a first pipe head and a second pipe head, one end of the first pipe head is provided with an internal threadpipe section and a positioning step located at the inner end of the internal thread pipe section, one end of the second pipe head is provided with an external thread pipe section, the external threadpipe section is in threaded connection with an internal and external thread pipe section arranged on the external thread pipe section in a sleeving mode, the internal and external thread pipe sectionis in threaded connection with the interior of the internal thread pipe section to connect the second pipe head and the first pipe head together, the internal thread pipe section and the external thread pipe section are connected together in a sealed mode through a sealing assembly, the external thread pipe section and the internal and external thread pipe section are completely contained in theinternal thread pipe section, and the external thread pipe section and the internal and external thread pipe section are connected together through an automatic assembling and disassembling mechanism.The pipeline joint structure has the advantages of being capable of preventing thread exposure at a pipeline joint and capable of achieving detachable connection of two pipelines, and is used for solving the problem that detachable connection and thread exposure avoidance cannot be both considered when two pipelines are connected in the prior art.

Description

[0001] This application is a divisional application with the application number 2018114826890, the application date is December 5, 2018, and the title is "Pipeline Joint Structure". technical field [0002] The invention relates to a mechanical structure on traditional Chinese medicine production equipment, in particular to a pipe joint structure. Background technique [0003] In the automatic production equipment of traditional Chinese medicine, it is necessary to connect two pipe bodies with detachable sealing to realize the delivery of liquid. The existing method of sealing and detachable connection of two pipe bodies is to set thread heads on the ends of the two pipe bodies, and then wrap the upper raw tape on the thread heads and screw them to the two ends of the internal thread pipe head To achieve a detachable connection, the sealing is achieved by deformation of the raw tape. Due to the change in the length of the thread head and the internal thread pipe head, the t...
