Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, and particularly relates to a pipeline connection structure. Background Art

[0002] A pipeline is a tubular structure used for transporting liquids, gases or solid particles, and is widely used in industry, construction and daily life. When assembling pipelines, a connection structure is usually required to assemble and connect multiple pipelines.

[0003] As disclosed in a pipeline connection structure with the authorization publication number CN221463172U, it includes a first pipeline, a connection cylinder and a second pipeline. Auxiliary installation frames are symmetrically and fixedly connected to the outside of the connection cylinder. Adjustment grooves are symmetrically opened on one side of the auxiliary installation frames. Slide plates are slidably connected inside the adjustment grooves, and a bidirectional lead screw is rotatably connected inside the auxiliary installation frames. The beneficial effect after adopting the above technical solution is that the function of positioning during the connection between pipelines is realized by setting positioning blocks and positioning grooves, which is convenient for subsequent installation and fixation of the pipelines.

[0004] Although the above patent facilitates the subsequent installation and fixation of pipelines, the bidirectional lead screw structure in the fixing mechanism is exposed to the outside. Affected by the environment for a long time, the lead screw will rust later, resulting in the inability to use the lead screw normally, so the pipeline cannot be disassembled normally. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pipeline connection structure to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A pipeline connection structure includes

[0008] a first pipeline and a second pipeline. Sealing discs are arranged on the same-side of the first pipeline and the second pipeline in the same direction. A number of U-shaped frames are arranged at equal arcs between the two sealing discs;

[0009] a movable sleeve, which is movably connected to the outside of the first pipeline and the second pipeline. A locking mechanism is arranged on the side of the movable sleeve close to the sealing disc.

[0010] Preferably, a number of clamping grooves are further arranged on the outside of the sealing disc, and the clamping grooves are matched with the U-shaped frames;

[0011] Preferably, the locking mechanism includes a clamping sleeve, which is movably arranged on the side of the movable sleeve close to the sealing disc. A number of positioning rods are arranged at equal arcs at one end of the clamping sleeve away from the movable sleeve. A positioning groove matched with the positioning rod is arranged between the U-shaped frame and the clamping groove;

[0012] Preferably, a guiding ring is further provided on one side of the movable sleeve close to the jacket, and the guiding ring is movably connected to the inside of the jacket;

[0013] Preferably, external threads are provided on the outer walls of the first pipe and the second pipe close to the sealing disc, and the movable sleeve is threadedly connected to the external threads;

[0014] Preferably, a plurality of guiding grooves are equiangularly arranged on the outer walls of the first pipe and the second pipe close to the sealing disc, and sliding blocks slidably connected to the guiding grooves are arranged on the inner wall of the jacket;

[0015] Preferably, a plurality of paddles are further arranged on the outer wall of the movable sleeve.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. For this pipe connection structure, through the cooperation of the first pipe, the second pipe, the movable sleeve, the jacket and the external threads, the external threads in this device are arranged on the outer walls of the first pipe and the second pipe, and after the first pipe and the second pipe are assembled, the external threads are blocked by the movable sleeve and the jacket. First, the external threads will not come into contact with the fluid inside the pipeline, avoiding rust and corrosion, and making the service life longer. Second, the external threads will not be affected by the external environment, avoiding failures and making it impossible to be used normally in the later stage.

[0018] 2. For this pipe connection structure, through the cooperation of the sealing disc, the U-shaped frame, the clamping groove, the positioning rod and the positioning groove, when the fluid inside the pipeline flows, the generated acting force will move the pipeline in the opposite direction. And in this device, a U-shaped frame is arranged between the two sealing discs. When the first pipe and the second pipe are stressed, the U-shaped frame can limit their outward movement. At the same time, the U-shaped frame is restricted by the positioning rod and will not move radially towards the sealing disc. Both the two-way angles are restricted, so the connection stability is higher and the operation is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0025] As Figures 1-4 shown, a technical solution provided by the present invention:

[0026] A pipeline connection structure includes Pipe 1 and Pipe 2. Sealing discs 3 are arranged on the same-side of Pipe 1 and Pipe 2 in the same direction. A number of U-shaped frames 4 are arranged at equal arcs between the two sealing discs 3. A number of card slots 6 are further arranged on the outer side of the sealing disc 3. The card slots 6 are matched with the U-shaped frames 4. External threads 11 are arranged on the outer wall of Pipe 1 and Pipe 2 near the sealing disc 3. The movable sleeve 5 is threadedly connected with the external thread 11;

[0027] In this embodiment, the external threads 11 in the present device are arranged on the outer walls of Pipe 1 and Pipe 2. After Pipe 1 and Pipe 2 are assembled, the external threads 11 are blocked by the movable sleeve 5 and the jacket 7. First, the external threads 11 will not come into contact with the fluid inside the pipeline, avoiding rust and corrosion, so that the service life is longer. Second, the external threads 11 will not be affected by the external environment, avoiding failures and resulting in abnormal use in the later stage.

[0028] As Figure 2 and Figure 4 shown, the movable sleeve 5 is movably connected to the outside of Pipe 1 and Pipe 2. A locking mechanism is arranged on the side of the movable sleeve 5 close to the sealing disc 3. The locking mechanism includes a jacket 7. The jacket 7 is movably arranged on the side of the movable sleeve 5 close to the sealing disc 3. A number of positioning rods 8 are arranged at equal arcs at one end of the jacket 7 away from the movable sleeve 5. A positioning groove 9 matching the positioning rods 8 is opened between the U-shaped frame 4 and the card slot 6. A guide ring 10 is further arranged on the side of the movable sleeve 5 close to the jacket 7. The guide ring 10 is movably connected to the inside of the jacket 7. A number of guide grooves 12 are arranged at equal arcs on the outer wall of Pipe 1 and Pipe 2 near the sealing disc 3. Slide blocks 13 slidably connected to the guide grooves 12 are arranged on the inner wall of the jacket 7. A number of paddles 14 are also arranged on the outer wall of the movable sleeve 5;

[0029] In this embodiment, when the fluid flows inside the pipeline, the generated acting force will move the pipeline in the opposite direction. In this device, a U-shaped frame 4 is arranged between the outsides of two sealing discs 3. When the pipeline 1 and the pipeline 2 are stressed, the U-shaped frame 4 can limit their outward movement. At the same time, restricted by the positioning rod 8, the U-shaped frame 4 will not move radially towards the sealing disc 3 either. With both bidirectional angles restricted, the connection stability is higher and the operation is more convenient.

[0030] Working principle: When assembling the pipeline 1 and the pipeline 2, abut the sealing discs 3 at the same-direction ends of the pipeline 1 and the pipeline 2, then successively snap a plurality of U-shaped frames 4 into the card slots 6, and then twist the movable sleeve 5. The movable sleeve 5 drives the clamping sleeve 7 to move horizontally forward until the positioning rod 8 on the front surface of the clamping sleeve 7 snaps into the positioning groove 9 between the sealing disc 3 and the U-shaped frame 4.

[0031] The foregoing has shown and described the basic principles, main features and advantages of the present utility model.
