Abstract

The utility model relates to a joint assembly, including first joint, pipeline locating part and second joint, the inside first through-hole that is used for supplying the pipeline to pass that is formed with of first joint, and the one end circumference of first joint is spaced apart to be equipped with a plurality of open slots to form a plurality of jack catchs. The pipeline limiting piece is used for extending into the pipeline at least partially, a second through hole which is engaged with the first joint is formed in the second joint, wherein the pipeline limiting piece is arranged in the second through hole, the second through hole comprises a conical section, when the clamping jaw extends from the large-diameter end of the conical section, the wall surface of the conical section can press the clamping jaw, and the clamping jaw can provide force for pressing the pipeline to the pipeline limiting piece. During installation, the claw is only required to be inserted into the conical section to be pressed and clamped through the inclined plane, so that quick connection of the pipeline and the joint assembly is completed, and the installation difficulty and time are reduced.

Description

Joint assembly Technical Field The present disclosure relates to the field of pipeline assembly technology, and in particular, to a joint assembly. Background When the existing pneumatic pipeline is in butt joint with a hydraulic pipeline, the pipeline joint is required to be used for butt joint, but the existing joint adopts a traditional threaded connection or flange butt joint mode, an operator is required to use a special tool for multiple rotation fastening, single disassembly and assembly operation is time-consuming and often requires a long time, the disassembly and assembly speed is low, and due to complex installation form, the operation is difficult to realize at an installation position with limited space, the reliability of an assembly process is reduced, and the efficiency of equipment maintenance and pipeline transformation is severely restricted. Disclosure of utility model The purpose of this disclosure is to provide a joint assembly to solve current pipeline joint dismouting speed slow, the inconvenient problem of assembly. To achieve the above object, the present disclosure provides a joint assembly including: A first joint, wherein a first through hole for a pipeline to pass through is formed in the first joint, and a plurality of open slots are formed at one end of the first joint at intervals in the circumferential direction so as to form a plurality of clamping claws; A pipeline limiting piece for extending into the pipeline at least partially, and A second joint, in which a second through hole is formed to be engaged with the first joint, Wherein, the pipeline locating part sets up in the second through-hole, the second through-hole includes the toper section, makes when the jack catch is followed the big footpath end of toper section is stretched into, the wall of toper section can be right the jack catch extrusion makes the jack catch provides the pipeline is pressed the power of pipeline locating part. Optionally, the bevel angle of the conical section is not less than 10 °. Optionally, the inner wall of the claw is formed with an inwardly protruding protrusion, and the thickness of the inner wall of the claw is gradually thinner from the protrusion to the tip of the claw. Optionally, the open slots are equally spaced on the first joint. Optionally, the number of the open slots is at least three. Optionally, a first step surface is formed at the position of the small diameter end of the conical section for limiting the claw in the axial direction. Optionally, the second through hole comprises a threaded section connected with the large-diameter end of the conical section, the first joint comprises a handle and a connecting section which are connected, and threads matched with the threaded section are formed on the outer wall of the connecting section. Optionally, a plurality of anti-skid grooves are circumferentially arranged on the handle. Optionally, the second through hole further comprises a limiting part placing section capable of being matched with the pipeline limiting part, the limiting part placing section is connected with the small diameter end of the conical section, a second step surface capable of being abutted to the pipeline limiting part is formed at one end, far away from the conical section, of the limiting part placing section, and the second step surface is used for limiting the pipeline limiting part in the axial direction. Optionally, the pipeline limiting piece comprises a boss protruding radially and used for propping against the shaft end of the pipeline, The limiting part placing section is formed with a third step surface matched with the boss and used for limiting the boss in the axial direction.
