Description

Technical Field

[0001] The utility model relates to the technical field of pipeline butt joint, in particular to a pipe joint with good firmness. Background Art

[0002] For a long time, when plumbers want to weld two single pipes together, they must first point the two ends of the two pipes together, which is not an easy task. They either use a lifting chain to pull them together, or use a pointed mold cut from angle steel to press them together, which is a waste of manpower and materials.

[0003] The utility model patent with announcement number CN 206268711 U proposes a pipeline maintenance tool, specifically a portable pipe joint. The utility model solves the technical problem of rapid maintenance and replacement of sealing components at the joints of two adjacent pipelines, including a main pipe callan, a secondary pipe callan, a cantilever, an adjustment disk, radial adjustment bolts, and axial adjustment bolts. The main pipe callan and the adjustment disk are connected by a cantilever, and the adjustment disk and the secondary pipe callan are connected by an axial adjustment bolt. A bolt hole is provided on the cantilever, and a radial adjustment bolt is provided in the bolt hole. The utility model has a compact structure, is easy to carry, and is flexible to operate. It is particularly suitable for use in small occasions and improves work efficiency.

[0004] In the above case, during use, the upper docking sleeve and the lower docking sleeve need to be manually supported to achieve the docking of the two mounting screw holes, which is not only very laborious, but also the screw holes are easily misaligned during docking. Therefore, the utility model provides a connecting pipe with good firmness to meet the needs. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A connecting pipe with good firmness comprises a No. 1 connecting sleeve and a No. 2 connecting sleeve, wherein the No. 1 connecting sleeve and the No. 2 connecting sleeve are connected by bolts; a positioning assembly, wherein the positioning assembly is used for pre-positioning the No. 1 connecting sleeve and the No. 2 connecting sleeve during installation, and the positioning assembly is connected to the No. 1 connecting sleeve and the No. 2 connecting sleeve; and a sealing assembly, wherein the sealing assembly is used for improving the sealing performance of the No. 1 connecting sleeve and the No. 2 connecting sleeve after installation, and the sealing assembly is connected to the No. 1 connecting sleeve and the No. 2 connecting sleeve.

[0007] Optionally, the positioning assembly includes a No. 1 mounting part and a No. 2 mounting part opened at both ends of the No. 1 docking sleeve and the No. 2 docking sleeve, the outer end of the No. 1 mounting part is provided with a positioning part, the outer end of the No. 2 mounting part is provided with a limiting part, and the interior of the positioning part is provided with a cavity that is compatible with the exterior of the limiting part.

[0008] Optionally, the cavity is provided with a guide portion facing outward.

[0009] Optionally, reinforcing ribs are provided outside the positioning portion.

[0010] Optionally, the sealing assembly includes a sealing ring fixedly connected between the No. 1 docking sleeve and the No. 2 docking sleeve.

[0011] Optionally, three protrusions are provided on the contact surface between the sealing ring and the outside of the water supply pipe, and a deformation cavity is opened inside the protrusion.

[0012] Optionally, a groove integrally formed with the three protrusions is provided inside the deformation cavity.

[0013] Optionally, a reset portion is provided outside the connection between the three grooves, the cross-section of the reset portion is arc-shaped, and the top of the reset portion abuts against the top of the inner cavity of the deformation cavity, and the sealing ring is integrally formed with the reset portion.

[0014] Compared with the prior art, the utility model has at least the following beneficial effects:

[0015] In the above scheme, by setting the positioning component, during the use of the docking device, the No. 1 mounting part and the No. 2 mounting part can be used to enable the docking sleeve to be quickly and accurately positioned during installation, thereby avoiding the problem of misalignment of the screw holes. The setting of the guide part further simplifies the installation process, so that the docking sleeve can be docked smoothly and smoothly. The addition of reinforcement ribs enhances the structural strength of the positioning part and improves the durability of the docking sleeve.

[0016] By setting the sealing assembly, during the docking process of the docking sleeve, since the contact surface between the raised end of the raised part and the pipe surface is small, the extrusion force and friction force on the sealing gasket during sliding positioning are relatively small, which effectively prevents the sealing gasket from flanging due to excessive friction during the docking process, and maintains the integrity and sealing performance of the sealing gasket. The raised part and the deformation cavity inside it allow the sealing ring to deform when under pressure. This deformation ability enables the sealing ring to adapt to pipes with slight size deviations, thereby ensuring the stability and reliability of the sealing effect. Even if there are slight changes or errors in the pipe size, the sealing ring can fill these gaps by deformation to achieve good sealing. When the raised part is worn by friction with the pipe surface, the worn sealing ring can be repaired to a certain extent due to the extrusion of the reset part. The reset part applies a certain pressure to the sealing ring through its special shape and structure, so that it can restore a certain deformation ability after being worn, thereby continuing to maintain a good sealing effect. This self-repairing ability not only extends the service life of the sealing ring, but also improves the firmness of the docking sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 1 to Figure 2As shown, an embodiment of the utility model provides a connecting pipe with good firmness, including a No. 1 docking sleeve 1 and a No. 2 docking sleeve 2, the No. 1 docking sleeve 1 and the No. 2 docking sleeve 2 are connected by bolts, and a positioning component is used for pre-positioning between the No. 1 docking sleeve 1 and the No. 2 docking sleeve 2 during installation. The positioning component is connected to the No. 1 docking sleeve 1 and the No. 2 docking sleeve 2, and the positioning component includes a No. 1 mounting portion 101 and a No. 2 mounting portion 201 opened at both ends of the No. 1 docking sleeve 1 and the No. 2 docking sleeve 2, the outer end of the No. 1 mounting portion 101 is provided with a positioning portion 102, the outer end of the No. 2 mounting portion 201 is provided with a limiting portion 202, and the interior of the positioning portion 102 is provided with an outer portion that is connected to the limiting portion 202. The cavity is adapted to be matched, and a guide portion 104 is opened on the outside of the cavity. A reinforcing rib 103 is arranged on the outside of the positioning portion 102. During the process of pipe docking, ensure that both sides of the pipe have been cleaned and prepared as necessary, such as removing debris, rust, etc., to ensure that the docking sleeve can fit tightly to the surface of the pipe. Next, start with the No. 1 docking sleeve 1 from one side of the damaged part of the pipe, gently slide and set it on the pipe, ensure that the No. 1 docking sleeve 1 fits tightly to the surface of the pipe without any gap, start with the No. 2 docking sleeve 2 from the other side of the damaged part of the pipe, and also gently slide and set it on the pipe. Like the No. 1 docking sleeve 1, ensure that the No. 2 docking sleeve 2 fits tightly to the surface of the pipe. , there is no gap, and the bottom of the No. 1 mounting part 101 is in conflict with the top of the No. 2 mounting part 201, so that the positioning part 102 is located on one side of the limiting part 202. At this time, the No. 1 docking sleeve 1 is slid toward the No. 2 docking sleeve 2. Because the internal cavity of the positioning part 102 is adapted to the external shape of the limiting part 202, the limiting part 202 can smoothly enter the cavity of the positioning part 102. At the same time, the guide part 104 opened on the outside of the cavity plays a guiding role, helping the limiting part 202 to enter the cavity more accurately, ensuring the accuracy of the installation. During the installation process, the reinforcing ribs 103 on the outside of the positioning part 102 play a role in enhancing the structural strength, so that the positioning part 102 can Withstand greater pressure and extrusion force to ensure the stability and reliability of the docking sleeve after installation. When the bottom of the No. 1 mounting portion 101 completely contacts the top of the No. 2 mounting portion 201, the cooperation between the positioning portion 102 and the limiting portion 202 firmly connects the No. 1 docking sleeve 1 and the No. 2 docking sleeve 2 together. At this time, the bolt connection step can be started. The two docking sleeves are tightly fixed together by bolts to complete the docking work. During the entire docking process, the positioning assembly ensures the rapid positioning and installation of the docking sleeve. At the same time, the design of the reinforcing ribs 103 and the guide portion 104 also enhances the structural strength and installation accuracy of the docking sleeve, and improves the efficiency and quality of the docking work.

[0031] In this embodiment, if Figures 1 to 4As shown, the sealing component is used to improve the sealing performance of the No. 1 docking sleeve 1 and the No. 2 docking sleeve 2 after installation. The sealing component is connected to the No. 1 docking sleeve 1 and the No. 2 docking sleeve 2. The sealing component includes a sealing ring 3 fixedly connected between the No. 1 docking sleeve 1 and the No. 2 docking sleeve 2. Three protrusions 301 are arranged on the contact surface between the sealing ring 3 and the outside of the water supply pipe. A deformation cavity 302 is opened inside the protrusion 301. A groove integrally formed with the three protrusions 301 is opened inside the deformation cavity 302. A reset portion 303 is arranged outside the connection between the three grooves. The cross-section of the reset portion 303 is in the shape of an arc, and the top of the reset portion 303 is aligned with the deformation cavity 30 2, the top of the inner cavity of the sealing ring 3 and the reset part 303 are integrally formed. The No. 1 butt sleeve 1 and the No. 2 butt sleeve 2 are preliminarily positioned on the damaged pipe through the positioning component to ensure that the bottom of the No. 1 mounting part 101 is tightly in contact with the top of the No. 2 mounting part 201, and the No. 1 butt sleeve 1 is slid toward the No. 2 butt sleeve 2 to achieve preliminary positioning. At this time, the raised part 301 on the sealing ring 3 will first be squeezed and contacted with the surface of the pipe. Due to the arc-shaped design of the raised part 301, the contact area between the raised part 301 and the surface of the water supply pipe is small, and the friction force is correspondingly reduced, which helps to reduce the flanging phenomenon of the sealing ring 3 during the sliding positioning process. After the pre-positioning is completed, the No. 1 butt sleeve is fixed by bolts. The sleeve 1 and the second docking sleeve 2 are locked and fixed. As the first docking sleeve 1 and the second docking sleeve 2 get closer, the deformation cavity 302 inside the protrusion 301 begins to be subjected to pressure and deforms. The deformation cavity 302 allows the sealing ring 3 to adapt to the tiny irregularities of the pipe surface, thereby improving the sealing effect. The groove inside the deformation cavity 302 works with the reset portion 303. When the protrusion 301 is subjected to pressure and deforms, the presence of the groove allows the protrusion 301 to produce a larger deformation locally to adapt to changes in the pipe surface. At the same time, the reset portion 303, as a supporting structure, provides a certain reaction force when the protrusion 301 is deformed, helping the sealing ring 3 to deform. After that, it returns to its original state. When the raised portion 301 is worn by friction with the pipe surface, due to the squeezing effect of the reset portion 303, the worn sealing ring 3 can be repaired to a certain extent. The arc structure of the reset portion 303 exerts a certain pressure on the raised portion 301, so that it can restore a certain deformation ability after being worn, thereby continuing to maintain a good sealing effect. When the No. 1 docking sleeve 1 and the No. 2 docking sleeve 2 are completely docked, they are tightened by bolts. During the tightening process of the bolts, the sealing ring 3 will be subjected to further pressure. However, at this time, due to the deformation of the raised portion 301 and the effect of the reset portion 303, the sealing ring 3 can be tightly fitted on the pipe surface to achieve the final sealing effect.

[0032] The work flow provided by the utility model cleans both sides of the pipeline, removes debris, rust, etc., ensures that the docking sleeve can fit tightly to the surface of the pipeline, gently slides the No. 1 docking sleeve 1 from one side of the damaged part of the pipeline and sleeves it on the pipeline to ensure a tight fit, similarly, gently slides the No. 2 docking sleeve 2 from the other side of the damaged part of the pipeline and sleeves it to ensure a tight fit, makes the bottom of the No. 1 mounting part 101 contact with the top of the No. 2 mounting part 201, so that the positioning part 102 is located on one side of the limiting part 202, slides the No. 1 docking sleeve 1 close to the No. 2 docking sleeve 2, so that the limiting part 202 smoothly enters the cavity of the positioning part 102, uses the guide part 104 for accurate guidance, and ensures that the sealing ring 3 is firmly connected to the No. 1 docking sleeve 1 and the No. 2 docking sleeve 2. The raised portion 301 on the sealing ring 3 contacts the surface of the pipe, and a smaller contact area is used to reduce friction and prevent flanging. The No. 1 docking sleeve 1 and the No. 2 docking sleeve 2 are tightly fixed together using bolts. As the bolts are tightened, the sealing ring 3 is subjected to pressure and deforms to adapt to the irregularities of the pipe surface, deformation and repair. The deformation cavity 302 inside the raised portion 301 allows it to deform when subjected to pressure, thereby improving the sealing effect. The reset portion 303 provides a reaction force when the raised portion 301 is deformed, thereby helping the sealing ring 3 to return to its original state. When the raised portion 301 is worn, the reset portion 303 helps the sealing ring 3 to repair itself to a certain extent. Through further tightening of the bolts, the sealing ring 3 fits tightly against the pipe surface to achieve the ultimate sealing effect.
