Description

Technical Field

[0001] The invention discloses a pipeline anti-detachment quick-twist joint, belonging to the field of pipeline joints. Background Art

[0002] A pipe swivel joint is a pipe fitting used to connect two sections of pipe, allowing a certain angle of rotation at the connection point. A pipe joint with a pagoda joint installed at one end of the elbow and a threaded joint at the other end of the elbow is one of the common pipe joint structures. The elbow and the threaded joint are connected by a rotating structure, that is, a limit ring installed at one end of the elbow is slidably installed in the internal threaded cap, and then one end of the threaded joint is threadedly connected in the internal threaded cap. On the one hand, the limit ring is restricted in the internal threaded cap, and on the other hand, the assembly of the threaded joint and the elbow is completed. In order to improve the stability of the connection between the threaded joint and the elbow, a longer threaded joint and an internal threaded cap are required. The longer threaded joint and the internal threaded cap take a longer time to assemble. For the situation where many threaded joints and elbows are assembled with each other, the overall assembly time is longer, affecting the assembly efficiency. Summary of the invention

The clamping block is arranged on the side of the second ear away from the first ear, and the clamping block contacts the second ear. A side of the clamping block away from the second ear is processed with an inclined surface, and two blind holes are provided on a side of the rectangular block facing the clamping block, and a first spring is inserted in the blind hole. Two column rods matching the blind holes are symmetrically installed at one end of the clamping block in the circular groove, and one end of the column rod away from the clamping block is inserted in the blind hole.

[0006] Specifically, a rectangular groove is processed in the circular groove, a threaded hole is processed in the rectangular groove and is arranged concentrically with the circular groove, a through hole is opened on one side of the rectangular block and is aligned with the threaded hole, and the end of the rectangular block away from the connecting ring is inserted in the rectangular groove, and the screw passes through the connecting ring and the through hole and is threadedly connected in the threaded hole.

[0007] Specifically, a second spring is installed on one side of the threaded hole close to the disk, and a disk is connected and fixed to one end of the second spring away from the disk. The disk is slidably installed in the threaded hole, and one end of the screw is in contact with the disk.

[0011] Specifically, a second hexahedron is sleeved on the internal thread cap, and the second hexahedron and the internal thread cap are an integrally formed structure.

[0012] Beneficial effects of the present invention:

[0013] 1. The ring is set on the internal thread cap, and the relative position of the ring and the internal thread cap is limited by two positioning rings, so that the ring can be rotated around the internal thread cap as needed, so that the perforation on the first ear is moved to a position aligned with the circular hole on the second ear, and the rotation of the elbow within a certain range is not affected.

[0014] 2. Screw the second thread head into the internal thread cap so that one end of the second thread head is in sliding contact with the limit ring. At this time, the internal thread cap and the second thread head work together to complete the assembly of the threaded joint formed by the first thread head, the first hexahedron and the second thread head and the elbow.

[0015] 3. After the second threaded head is screwed into the internal threaded cap, the position of the ring is adjusted to align the first ear with the second ear, and then the plug-in column is inserted into the channel formed by the perforation and the circular hole. At this time, under the support of the first spring, the clamping block protrudes to the outside of the arc-shaped opening and the clamping block fits with the side of the second ear away from the first ear. At this time, the plug-in column, the clamping block and the disc work together to limit the relative position of the first ear and the second ear, thereby limiting the relative position of the second threaded head and the internal threaded cap. On the one hand, it is beneficial to reduce the length of the second threaded head and the internal threaded cap, shorten the time spent on assembling the second threaded head and the internal threaded cap, and improve the assembly efficiency. On the other hand, under the joint action of the plug-in column, the clamping block and the disc, the second threaded head and the internal threaded cap are prevented from loosening due to vibration, thereby playing a role in preventing them from falling off.

[0016] 4. Insert one end of the rectangular block in the rectangular groove to limit the position of the rectangular block and prevent the rectangular block from rotating freely in the circular groove. Process an inclined surface on the clamping block so that when the plug-in column passes through the circular hole, the inclined surface on the clamping block first contacts the inner wall of the circular hole. Under the pressure of the inner wall of the circular hole, the clamping block retracts into the arc-shaped opening. At this time, the clamping block drives the column rod to squeeze the first spring. After the clamping block passes through the circular hole, the clamping block protrudes to the outside of the arc-shaped opening under the action of the rebound force of the first spring, so that the screw passes through the through hole and is screwed into the threaded hole, completing the assembly of the plug-in column, the rectangular block and the connecting ring to form a structure. After removing the screw, the rectangular block can be taken out, so that the clamping block is separated from the arc-shaped opening, which is convenient for taking the plug-in column out of the circular hole.

[0017] 5. When one end of the screw is screwed into the threaded hole, the screw squeezes the disc, and the disc squeezes the second spring, causing the second spring to produce elastic deformation. Under the action of the second spring's rebound force, the screw is prevented from loosening at will. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] See also Figure 1-Figure 10The outer surface of the end of the plug-in column 11 away from the disc 15 is symmetrically provided with two arc-shaped openings 27, which are communicated with the circular groove 21. The two arc-shaped openings 27 are both inserted with a clamping block 12. The clamping block 12 is arranged on the side of the second ear 6 away from the first ear 5. The clamping block 12 contacts the second ear 6. The side of the clamping block 12 away from the second ear 6 is processed with an inclined surface.

Under the pressure of the inner wall of the circular hole 17, the clamping block 12 retracts into the arc-shaped opening 27. At this time, the clamping block 12 drives the column rod 29 to squeeze the first spring 30. After the clamping block 12 passes through the circular hole 17, the clamping block 12 protrudes to the outside of the arc-shaped opening 27 under the action of the rebound force of the first spring 30, so that the screw 14 passes through the through hole 25 and is screwed into the threaded hole 22, completing the assembly of the plug-in column 11, the rectangular block 26 and the connecting ring 13 to form a structure. After removing the screw 14, the rectangular block 26 can be taken out, so that the clamping block 12 is separated from the arc-shaped opening 27, which is convenient for taking the plug-in column 11 out of the circular hole 17.
