In order to achieve the above purpose, the utility model adopts the technical scheme that: the clamping mechanism at the joint of the pipelines is characterized by comprising a first pipeline and a second pipeline, wherein the outer wall of the first pipeline is provided with threads and is fixed with a thread groove on the inner wall of the second pipeline in a threaded rotating connection mode, and the joint of the first pipeline and the second pipeline is provided with the clamping mechanism;

clamping mechanism includes first arc and second arc, and wherein, first arc and second arc can make up jointly and form a ring of arranging in on the pipeline outer wall, homogeneous body shaping in first arc and second arc outer wall both sides is connected with parallel arrangement's bulge, it is fixed to have seted up the mounting hole on the bulge and realize locking through the positioning bolt subassembly, positioning bolt subassembly outer wall one end is close to the bulge on the second arc and is connected with locking gasket, just first arc and second arc inner wall viscidity all around is fixed with arranges the outside rubber packing pad of pipeline in.

Furthermore, the outer wall of the first pipeline and the outer wall of the second pipeline are all provided with a slope surface at one end far away from the joint of the first pipeline and the second pipeline.

Furthermore, the bottom end of the locking gasket is provided with an anti-drop ring connected with the positioning bolt assembly.

Furthermore, the bulges on the first arc-shaped plate and the second arc-shaped plate are symmetrically arranged relative to the center of the pipeline.

Furthermore, a sealing opening arranged between the first arc-shaped plate and the second arc-shaped plate is formed in the rubber sealing gasket.

The utility model has the technical effects that: the two pipelines are firstly installed and fixed in a threaded rotating connection mode, then the clamping mechanism is further jointed with the connection position of the two pipelines through a circular ring formed by a first arc-shaped plate and a second arc-shaped plate, then the convex part is further clamped and fixed by a locking gasket on the positioning bolt assembly, and the rubber sealing ring fixed on the inner wall of the arc-shaped plate can wrap the pipeline, thereby playing a role of sealing, in addition, even if the liquid in the pipeline is at a higher temperature, because of the temperature resistance of the rubber, the liquid is not easy to leak, the slope surface arranged on the outer wall of the pipeline can play a role in buffering the liquid flow, the flow velocity is prevented from being high, the clamping mechanism at the pipeline joint improves the use performance of the device, is stable in connection, ensures the sealing performance of the pipeline joint, is convenient to disassemble and prolongs the service life of the device.

Detailed Description

Referring to the attached drawings 1-3, a clamping mechanism for a pipeline joint comprises a first pipeline 1 and a second pipeline 2, wherein the outer wall of the first pipeline 1 is provided with threads and is fixed with a thread groove on the inner wall of the second pipeline 2 in a threaded rotating connection mode, and a clamping mechanism 3 is arranged at the joint of the first pipeline 1 and the second pipeline 2;

clamping mechanism 3 includes first arc 4 and second arc 5, and wherein, first arc 4 and second arc 5 can make up jointly and form a ring of arranging in on the pipeline outer wall, the homogeneous body shaping in first arc 4 and 5 outer walls of second arc both sides is connected with parallel arrangement's bulge 6, it is fixed to have seted up the mounting hole on bulge 6 and realize locking through positioning bolt subassembly 7, 7 outer wall one ends of positioning bolt subassembly are close to bulge 6 on the second arc 5 and are connected with locking gasket 8, just first arc 4 and 5 inner walls of second arc are fixed with all around viscidity and arrange in the outside rubber packing pad 9 of pipeline.

The concrete embodiment of this scheme does, first pipeline 1 and 2 outer walls of second pipeline keep away from both junction one end all around and have seted up domaticly, and the domatic setting of pipeline outer wall can play the cushioning effect to liquid flow, and it is very fast to prevent the velocity of flow.

The concrete embodiment of this scheme does, 8 bottoms of lock washer are equipped with the anticreep ring that is connected with positioning bolt subassembly 7, the bulge 6 homogeneous phases on first arc 4 and the second arc 5 set up for the central symmetry of pipeline, and the bulge 6 that the symmetry set up can follow both ends and carry out the tight work of clamp to the pipeline, when guaranteeing the stability of connecting, can improve the clamp force to the pipeline.
