Description

Technical Field

[0001] The utility model relates to the technical field of spiral joints, in particular to an anti-slip and anti-retreat structure applied to spiral joints. Background Art

[0002] The anti-slip and anti-retraction structure of the spiral joint is usually used to prevent the joint from loosening or falling off due to vibration or other external forces during use, so as to avoid affecting the normal use of the spiral joint.

[0003] After searching, the Chinese patent with publication number CN214839130U discloses a hose joint with a locking and anti-backup groove, including a joint nut, a core tube and a locking and anti-backup groove; the core tube is welded to the joint nut, and the locking and anti-backup groove includes a buckling rod, one end of the buckling rod is engaged with the buckling groove opened on the core tube, and the other end is fixedly connected to a cross bar; the cross bar is movably provided with a mounting plate on the side away from the core tube, and threaded holes are opened on both sides of the mounting plate, and fastening screws are spirally penetrated in the threaded holes; a number of positioning rods are fixedly connected to the side of the mounting plate facing the core tube, and the positioning rods are arranged through the cross bar.

[0004] Based on the above search and combined with existing technology findings;

[0005] Although the above patent can achieve an anti-slip and anti-retreat structure for the joint through the locking anti-retreat groove, it is inconvenient to use because it is locked and fixed by a fastening screw. The common anti-slip and anti-retreat structure is a threaded structure, but it may fail in a high vibration environment, so it has certain limitations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes an anti-slip and anti-retreat structure applied to a spiral joint. The anti-slip and anti-retreat block provided can ensure the stability of the connection between the spiral connection part 2 and the spiral connection part 1, and it has low cost and is easy to use.

[0007] The technical solution to achieve the purpose of the utility model is: an anti-slip and anti-retreat structure applied to a spiral joint, including a spiral connection part 1, a threaded connection tube is fixedly installed on the surface of the spiral connection part 1, and the outside of the spiral connection part 1 is threadedly connected to a spiral connection part 2 through the threaded connection tube.

[0008] In some embodiments, a plurality of anti-slip and anti-retraction blocks are fixedly installed on the inner top of the second spiral connection part, and each of the anti-slip and anti-retraction blocks is arranged at an angle.

[0009] In some embodiments, a rubber tube and a plurality of elastic clips are fixedly mounted on the surface of the threaded connection tube.

[0010] Compared with the prior art, the present invention has the following significant advantages:

[0011] First: The utility model provides an elastic clip on the threaded connection cylinder, and utilizes the anti-slip stop block provided on the spiral connection part 2, and the anti-slip stop block is arranged at a certain angle. When the spiral connection part 2 needs to be tightened, the anti-slip stop block can press the elastic clip to move, thereby facilitating the normal rotation and tightening of the spiral connection part 2. After clockwise tightening, the anti-slip stop block can be clamped between an adjacent pair of elastic clips. When rotated counterclockwise, the anti-slip stop block can achieve a clamping and fixing effect with the elastic clip, thereby preventing the spiral connection part 2 from rotating, causing the connection to loosen, thereby achieving a stable connection and fixing effect.

[0012] Secondly, the present invention facilitates the stable connection between the spiral connection part 1 and the spiral connection part 2 by providing a threaded connection cylinder, thereby ensuring that the cable passes through the inside of the two to achieve a fixed connection effect.

[0013] The invention solves the problem that although the anti-slip and anti-retreat structure of the joint can be achieved by locking the anti-retreat groove, it is inconvenient to use because it is locked and fixed by a fastening screw. The common anti-slip and anti-retreat structure is a threaded structure, which may fail in a high vibration environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The present invention provides an improved anti-slip and anti-retraction structure for a spiral joint. The technical solution of the present invention is:

[0024] like Figures 1-4 As shown, an anti-slip and anti-retreat structure applied to a spiral joint includes a spiral connection part 1, a threaded connection tube 3 is fixedly installed on the surface of the spiral connection part 1, and the outside of the spiral connection part 1 is threadedly connected to the spiral connection part 2 through the threaded connection tube 3. The set threaded connection tube 3 can stably connect the spiral connection part 1 and the spiral connection part 2 2 through a threaded connection.

[0025] Further, as attached Figure 5 As shown, a plurality of anti-slip stop blocks 5 are fixedly installed on the inner top of the spiral connection part 2, each anti-slip stop block 5 has a certain inclination, and a slope is provided at the end of each anti-slip stop block 5. By setting a plurality of anti-slip stop blocks 5, it is possible to ensure that the spiral connection part 2 is tightened clockwise. Specifically, when tightening clockwise, the slope at the end of the anti-slip stop block 5 is against the side of the elastic clip 4 in the subsequent clockwise direction, and the elastic clip 4 is pushed inward by the action of the slope; but when rotating in the opposite direction, the planar area of ​​the anti-slip stop block 5 is against the side of the elastic clip 4 in the counterclockwise direction, so that the anti-slip stop block 5 can play a certain obstructive role and prevent the spiral connection part 2 from rotating unnecessary.

[0026] Furthermore, a rubber tube 6 and a plurality of elastic clips 4 are fixedly installed on the surface of the threaded connection tube 3. The elastic clips 4 can achieve a clamping and fixing effect on the anti-slip and anti-retreat block 5, thereby cooperating with the anti-slip and anti-retreat block 5 to achieve a fixing and anti-loosening effect on the spiral connection part 2.

[0027] The specific working method is: the spiral connection part 2 is fixedly connected to the spiral connection part 1 through the threaded connection tube 3. When tightened clockwise, the anti-slip stop block 5 can normally rotate with the spiral connection part 2 between the elastic clip 4. When the anti-slip stop block 5 moves, it can press the elastic clip 4 to shrink inward. As it is continuously tightened, the elastic clip 4 and the rubber tube 6 can shrink inward to fix the cable. After it is fixed, through the set elastic clip 4 and the anti-slip stop block 5, when the spiral connection part 2 tends to rotate counterclockwise, its anti-slip stop block 5 can clamp and fix the elastic clip 4 to a certain extent, which can prevent the spiral connection part 2 from rotating counterclockwise without the action of external force, thereby affecting the connection stability between the spiral connection part 1 and the spiral connection part 2.

[0028] The technical means disclosed in the present invention are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacements of the above technical features. Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
