Description

Technical Field

[0001] This utility model belongs to the field of lubricating oil unloading technology, and in particular relates to a three-way connector for unloading ultra-high viscosity lubricating oil. Background Technology

[0002] Oil unloading tee connectors typically have three channels, enabling functions such as oil distribution, mixing, or diversion. Their internal flow channels are optimized to reduce fluid resistance and pressure loss, ensuring smooth oil flow.

[0003] Existing unloading tee connectors require connection to lubricating oil delivery pipelines during use. When connecting the unloading tee connector to the delivery pipeline, it is usually connected by flanges and then fixed with multiple bolts. This method is not only complicated and labor-intensive, but also requires continuous adjustment of the flange hole positions after flange connection in order to insert the bolts, resulting in low connection efficiency. Therefore, we have proposed an ultra-high viscosity lubricating oil unloading tee connector. Utility Model Content

[0004] The purpose of this invention is to provide a high-viscosity lubricating oil unloading tee connector. By setting a connection assembly, specifically pulling the pull ring towards the unloading tee releases the spherical locking block. The delivery pipe is then inserted into the connecting pipe. As the delivery pipe pushes the spherical locking block against the spring, the arc-shaped groove on the delivery pipe moves to the position of the spherical locking block. The spherical locking block then resets under the elastic action of the spring and enters the arc-shaped groove, thus locking and fixing the delivery pipe. This method allows for rapid connection, is convenient and efficient, and solves the problem that existing unloading tee connectors, when connected to delivery pipelines, typically use flanges and multiple bolts for fixing, which is not only complex but also labor-intensive.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a high viscosity lubricating oil unloading tee connector, comprising an unloading tee with three connecting pipes fixedly connected to its outer side. The three connecting pipes are connected to identical parts. A docking assembly is provided on the outer side of each connecting pipe, the docking assembly including a conveying pipe. A pull ring is provided on the outer side of each connecting pipe. An arc-shaped annular groove is formed on the outer surface of the conveying pipe. An annular groove is formed inside the connecting pipe. Several spherical locking blocks are provided inside the annular groove. A spring is sleeved on the outer side of each of the spherical locking blocks. A hemispherical block is fixedly connected to the side of each spherical locking block away from the conveying pipe via a connecting rod. The connecting rod on the spherical locking block is slidably connected to the connecting pipe. The side of the spring near the spherical locking block is fixedly connected to the surface of the spherical locking block, and the side of the spring away from the spherical locking block is fixedly connected to the inner wall of the annular groove.

[0007] Furthermore, a conical inner ring is fixedly connected to the inner wall of the connecting pipe, and a sealing gasket is fitted on the left side of the conical inner ring. The side of the conveying pipe near the conical inner ring contacts the surface of the sealing gasket. The conveying pipe is inserted into the connecting pipe, and a sealing gasket is fitted on the outer surface of the conveying pipe. The side of the sealing gasket near the connecting pipe contacts the surface of the connecting pipe.

[0008] Furthermore, an inner convex ring is fixedly connected to the inner wall of the pull ring, and two annular plates are fixedly connected to the outer surface of the connecting tube. A second spring is fixedly connected to the side of the left annular plate away from the inner convex ring and the side of the right annular plate close to the inner convex ring. The side of the left spring away from the inner convex ring is fixedly connected to the inner wall of the pull ring, and the side of the right spring close to the inner convex ring is fixedly connected to the surface of the inner convex ring.

[0009] Furthermore, the inner side of the inner convex ring contacts the surface of the hemispherical block, and after the conveying pipe and the connecting pipe are connected, the spherical block enters the arc-shaped ring groove and contacts the inner wall of the arc-shaped ring groove.

[0010] Furthermore, a plug ring is fixedly connected to the right side of the conveying pipe, the outer side of the plug ring is in contact with the inner side of the conical inner ring, and the left side of the inner convex ring is set with a conical surface.

[0011] Furthermore, a handle is provided above the unloading tee, and a rotating rod is fixedly connected to the bottom of the handle. The rotating rod passes through the unloading tee and extends into it. The rotating rod is rotatably connected to the unloading tee. A sealing block is fixedly connected to the outer surface of the rotating rod. The outer side of the sealing block contacts the inner wall of the unloading tee. A directional groove is provided at the top of the handle, and the directional groove is aligned with the direction of the sealing block.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, by setting up a docking component, specifically pulls the pull ring towards the unloading tee, releasing the spherical locking block. The delivery pipe is then inserted into the connecting pipe. When the delivery pipe pushes the spherical locking block to compress the first spring, the arc-shaped groove on the delivery pipe moves to the position of the spherical locking block. The spherical locking block then resets under the elastic action of the first spring and enters the arc-shaped groove, thereby locking and fixing the delivery pipe. This method can quickly complete the docking, making the operation convenient and more efficient.

[0014] 2. This utility model features an inner convex ring. Specifically, after the conveying pipe is connected, the pull ring can be released. At this time, the pull ring will be reset by the elastic action of two springs, and the inner convex ring will move to the position above the hemispherical block and squeeze the hemispherical block. At this time, the spherical block will be tightly attached to the inner wall of the arc-shaped groove on the conveying pipe, thereby improving the fixing effect and preventing the conveying pipe from falling off.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figure 1-6As shown, this utility model is a tee connector for unloading ultra-high viscosity lubricating oil, including an unloading tee 1. Three connecting pipes 11 are fixedly connected to the outside of the unloading tee 1. The parts connected to the three connecting pipes 11 are the same. A docking assembly 12 is provided on the outside of the connecting pipes 11. The docking assembly 12 includes a conveying pipe 121. A pull ring 122 is provided on the outside of the connecting pipe 11. An arc-shaped annular groove 212 is opened on the outer surface of the conveying pipe 121. An annular groove 113 is opened inside the connecting pipe 11. Several spherical locking blocks 124 are arranged inside the annular groove 113. A spring 241 is sleeved on the outside of each of the spherical locking blocks 124. A hemispherical block 242 is fixedly connected to the side of each of the spherical locking blocks 124 away from the conveying pipe 121 by a connecting rod. The connecting rod on the spherical locking block 124 is slidably connected to the connecting pipe 11. Next, the side of spring 241 closest to the spherical locking block 124 is fixedly connected to the surface of the spherical locking block 124, and the side of spring 241 away from the spherical locking block 124 is fixedly connected to the inner wall of the annular groove 113. By setting the docking assembly 12, specifically by pulling the pull ring 122 towards the oil unloading tee 1, the spherical locking block 124 is released from its fixed position. The delivery pipe 121 is then inserted into the connecting pipe 11. When the delivery pipe 121 pushes the spherical locking block 124 to squeeze the spring 241, and the arc-shaped annular groove 212 on the delivery pipe 121 moves to the position of the spherical locking block 124, the spherical locking block 124 is reset by the elastic action of the spring 241 and enters the arc-shaped annular groove 212, thereby locking and fixing the delivery pipe 121. This method can quickly complete the docking, and the operation is convenient and more efficient.

[0027] A conical inner ring 111 is fixedly connected to the inner wall of the connecting pipe 11. A sealing gasket 112 is fitted on the left side of the conical inner ring 111. The side of the conveying pipe 121 near the conical inner ring 111 contacts the surface of the sealing gasket 112. The conveying pipe 121 is inserted into the connecting pipe 11. A sealing gasket 211 is fitted on the outer surface of the conveying pipe 121. The side of the sealing gasket 211 near the connecting pipe 11 contacts the surface of the connecting pipe 11. Both the sealing gasket 112 and the sealing gasket 211 play a sealing role, improving the sealing effect of the conveying pipe 121 after installation.

[0028] An inner convex ring 123 is fixedly connected to the inner wall of the pull ring 122. Two annular plates 125 are fixedly connected to the outer surface of the connecting pipe 11. A second spring 126 is fixedly connected to both the left annular plate 125 away from the inner convex ring 123 and the right annular plate 125 near the inner convex ring 123. The left spring 126 away from the inner convex ring 123 is fixedly connected to the inner wall of the pull ring 122, and the right spring 126 near the inner convex ring 123 is fixedly connected to the inner wall of the pull ring 122. The ring 123 is fixedly connected to the surface. By setting the inner convex ring 123, specifically after the conveying pipe 121 is connected, the pull ring 122 can be released. At this time, the pull ring 122 will be reset by the elastic action of the two springs 126, and the inner convex ring 123 will move to the position above the hemispherical block 242 and squeeze the hemispherical block 242. At this time, the spherical locking block 124 will be tightly attached to the inner wall of the arc-shaped ring groove 212 on the conveying pipe 121, thereby improving the fixing effect and preventing the conveying pipe 121 from falling off.

[0029] The inner side of the inner convex ring 123 contacts the surface of the hemispherical block 242. After the conveying pipe 121 is connected to the connecting pipe 11, the spherical locking block 124 enters the arc-shaped ring groove 212 and contacts the inner wall of the arc-shaped ring groove 212. Since the spherical locking block 124 is spherical, the conveying pipe 121 can smoothly push the spherical locking block 124 when it is connected, which is convenient for installation.

[0030] A plug ring is fixedly connected to the right side of the conveying pipe 121. The outer side of the plug ring contacts the inner side of the conical inner ring 111. The left side of the inner convex ring 123 is set with a conical surface. Since the hemispherical block 242 is hemispherical and the left side of the inner convex ring 123 is set with a conical surface, the inner convex ring 123 can smoothly push the hemispherical block 242.

[0031] A handle 13 is provided above the unloading tee 1. A rotating rod 131 is fixedly connected to the bottom of the handle 13. The rotating rod 131 passes through the unloading tee 1 and extends into the interior. The rotating rod 131 is rotatably connected to the unloading tee 1. A sealing block 132 is fixedly connected to the outer surface of the rotating rod 131. The outer side of the sealing block 132 contacts the inner wall of the unloading tee 1. A guide groove 133 is provided at the top of the handle 13. The direction of the guide groove 133 is consistent with that of the sealing block 132.

[0032] One specific application of this embodiment is:

[0033] In use, pull the pull ring 122 towards the unloading tee 1. The pull ring 122 will then move the inner convex ring 123, which in turn stretches and compresses the two springs 126. The inner convex ring 123 will then move away from the hemispherical block 242, releasing the spherical locking block 124. At this point, insert the delivery pipe 121 into the connecting pipe 11. When the delivery pipe 121 contacts the spherical locking block 124, it will push the spherical locking block 124, causing the springs to... When spring 241 is squeezed, the conveying pipe 121 passes smoothly through the spherical locking block 124. When the arc-shaped groove 212 on the conveying pipe 121 moves to the position of the spherical locking block 124, the spherical locking block 124 is reset by the elastic action of spring 241 and enters the arc-shaped groove 212, thus locking and fixing the conveying pipe 121. At this time, the conveying pipe 121 will contact the sealing gasket 112 on the conical inner ring 111 inside the connecting pipe 11, achieving a sealing function. After the delivery pipe 121 is connected, the pull ring 122 can be released. At this time, the pull ring 122 will be reset by the elastic action of the two springs 126, and the inner convex ring 123 will move to the position above the hemispherical block 242 and squeeze the hemispherical block 242. At this time, the spherical locking block 124 will be tightly attached to the inner wall of the arc-shaped ring groove 212 on the delivery pipe 121, thereby improving the fixing effect and preventing the delivery pipe 121 from falling off. After the delivery pipe 121 is installed, the surface will contact the sealing gasket 211, which can play a sealing role again. This method can quickly complete the connection, and the operation is convenient and efficient. Other connecting pipes 11 can be connected to the delivery pipe 121 in the same way. Finally, the operator turns the handle 13 to drive the rotating rod 131 to rotate, and the sealing block 132 will rotate with it, thereby sealing different connecting pipes 11 according to different needs. The guide groove 133 is used to guide, making it easy for the operator to observe the sealing position.
