Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy pipelines, and particularly relates to a positioning connecting piece for water conservancy pipelines. Background Technique

[0002] Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil, natural gas, agricultural irrigation, hydraulic engineering and various industrial installations. Water conservancy and hydropower pipelines are specifically used for the water conservancy and hydropower industries. As an important accessory for connecting pipelines, pipeline connecting pieces can play a role in firm connection. Therefore, the pipeline connecting pieces in the construction of water conservancy pipelines are a relatively important link.

[0003] At present, for existing water conservancy pipelines, during installation, most of them are spliced and installed between two pipelines through flanges and bolts. During long-term use, the water in the pipeline will cause certain vibrations to the pipeline during the flowing process, resulting in the loosening of the bolts, affecting the transportation of materials. For this reason, we propose a positioning connecting piece for water conservancy pipelines. Content of the Utility Model

[0004] The purpose of the utility model is to provide a positioning connecting piece for water conservancy pipelines to solve the existing problems mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A positioning connecting piece for water conservancy pipelines, including a composite pipeline main body, a pressing groove and a pressing plate. Ring-shaped convex edges are fixedly welded to the outer peripheries of both ends of the composite pipeline main body. A plurality of grooves are equidistantly arranged on the outer periphery of one side of the ring-shaped convex edge. Pressing grooves are arranged on the inner walls of the grooves. A flap is movably connected to the side of the ring-shaped convex edge provided with the groove through a pin shaft. The flap is of a frame structure. A sliding sleeve is fixedly embedded at one end of the inner side of the flap. A threaded sleeve is slidably connected inside the sliding sleeve. A screw rod is rotatably connected to the inside of the sliding sleeve through a bearing. The screw rod extends into the threaded sleeve and is helically connected thereto. One end of the threaded sleeve extending outside the sliding sleeve is fixedly provided with a pressing plate.

[0006] Preferably, the outer end of the flap is rotatably connected to a spring sleeve through a bearing. The bottom of the spring sleeve is fixedly connected to the top of the screw rod. A telescopic column is slidably connected to the top end inside the spring sleeve. A knob is fixedly installed at the top of the telescopic column. A return spring is arranged inside the spring sleeve. The two ends of the return spring are respectively fixedly connected to the spring sleeve and the telescopic column.

[0007] Preferably, limiting grooves are arranged on the inner walls of both sides inside the spring sleeve and the sliding sleeve. Limiting blocks are arranged on both sides of one end of the telescopic column and the threaded sleeve. The limiting blocks extend into the corresponding limiting grooves and are slidably connected to their inner walls.

[0008] Preferably, a positioning hole is provided on one side of the outer ring of the bearing on the outer periphery of the spring sleeve. The positioning hole is provided around the spring sleeve for one week. A positioning post is fixedly installed on one side of the knob, and the positioning post is inserted into the positioning hole.

[0009] Preferably, a splicing groove is provided inside one end of the composite pipe body. A first gasket is arranged inside the splicing groove, and the first gasket is fixedly connected with the inner wall of the splicing groove by gluing.

[0010] Preferably, a splicing protrusion is provided outside one end of the composite pipe body away from the splicing groove. A second gasket is sleeved on the outer periphery of the splicing protrusion, and the second gasket is fixedly sleeved on the outer periphery of the splicing protrusion by gluing.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. By using the driving screw to drive the threaded sleeve to extend outwards, the pressing plate is pushed to extend into the pressing groove and tightly squeezed, so that the two annular convex edges are tightly spliced. Then, with the cooperation of the positioning post and the positioning hole, the telescopic column is positioned. Under the action of the limiting groove and the limiting block, the spring sleeve and the screw are limited to prevent the screw from rotating during use, thus avoiding the loosening of the connection.

[0013] 2. By arranging a return spring inside the spring sleeve and cooperating with the telescopic column, the function of driving the knob to reset is realized. After the knob is rotated tightly, under the action of the return spring, the telescopic column is pulled to contract, thereby driving the knob and the positioning post to reset, and inserting the positioning post into the positioning hole to realize the positioning function, ensuring its stability.

[0019] 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 efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution for a positioning connector of a water conservancy pipeline: including a composite pipeline main body 1, a pressing groove 8 and a pressing plate 10. Annular convex edges 6 are fixedly welded to the outer peripheries of both ends of the composite pipeline main body 1. A plurality of grooves 7 are equidistantly opened on the outer periphery of one side of the annular convex edge 6. A pressing groove 8 is opened on the inner wall of the inside of the groove 7. A flap 9 is movably connected to the side of the annular convex edge 6 where the groove 7 is opened through a pin shaft. The flap 9 is of a frame structure. A sliding sleeve 13 is fixedly embedded at one end of the inner side of the flap 9. A threaded sleeve 11 is slidably connected inside the sliding sleeve 13. A screw rod 15 is movably connected to the inside of the sliding sleeve 13 through a bearing. The screw rod 15 extends into the threaded sleeve 11 and is helically connected thereto. One end of the threaded sleeve 11 extending outside the sliding sleeve 13 is fixedly provided with a pressing plate 10.

[0021] Specifically, the outer end of the flap 9 is movably connected to a spring sleeve 16 through a bearing. The bottom of the spring sleeve 16 is fixedly connected to the top of the screw rod 15. The top end inside the spring sleeve 16 is slidably connected to a telescopic column 17. A knob 19 is fixedly installed at the top of the telescopic column 17. A return spring 18 is provided inside the spring sleeve 16. Both ends of the return spring 18 are fixedly connected to the spring sleeve 16 and the telescopic column 17 respectively.

[0022] Specifically, limit grooves 14 are opened on both inner side walls of the inside of the spring sleeve 16 and the sliding sleeve 13. Limit blocks 12 are provided on both sides of one end of the telescopic column 17 and the threaded sleeve 11. The limit blocks 12 extend into the corresponding limit grooves 14 and are slidably connected to their inner walls.

[0023] Specifically, a positioning hole 21 is opened on one side of the outer ring of the bearing of the outer periphery of the spring sleeve 16. The positioning hole 21 is opened around the spring sleeve 16 for one week. A positioning column 20 is fixedly installed on one side of the knob 19. The positioning column 20 is inserted into the positioning hole 21.

[0024] Specifically, a splicing groove 2 is formed inside one end of the composite pipe body 1, and a first gasket 3 is arranged inside the splicing groove 2. The first gasket 3 is fixedly connected to the inner wall of the splicing groove 2 by gluing.

[0025] Specifically, a splicing protrusion 4 is arranged outside the end of the composite pipe body 1 away from the splicing groove 2, and a second gasket 5 is sleeved on the outer periphery of the splicing protrusion 4. The second gasket 5 is fixedly sleeved on the outer periphery of the splicing protrusion 4 by gluing.

[0026] In this embodiment, during use, the two composite pipe bodies 1 are spliced by means of the splicing groove 2 and the splicing protrusion 4, and the sealing performance of their connection is ensured by the first gasket 3 and the second gasket 5. After splicing, the flap 9 on the annular convex edge 6 is flipped, so that the pressing plate 10 inside the flap 9 is flipped into the groove 7. Then, the knob 19 is pulled outwards, so that the positioning post 20 is disengaged from the positioning hole 21. Then, the knob 19 is rotated, so as to drive the telescopic column 17 to rotate. Since the telescopic column 17 and the spring sleeve 16 are limited and slidably connected through the limiting groove 14 and the limiting block 12, the telescopic column 17 can drive the spring sleeve 16 to rotate. Also, because the spring sleeve 16 is fixedly connected to the screw rod 15, the screw rod 15 is driven to rotate. In cooperation with the fact that the sliding sleeve 13 and the threaded sleeve 11 are limited and slidably connected through the limiting block 12 and the limiting groove 14, the threaded sleeve 11 is driven to telescopically move inside the sliding sleeve 13, so that the threaded sleeve 11 drives the pressing plate 10 to move into the pressing groove 8, and the two mutually butted annular convex edges 6 are compacted, so that they keep in close contact and the stability of splicing is improved.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
