Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline connection, and particularly relates to a pipeline connector for boosting rural water supply pipelines. Background Art

[0002] A pipeline connector is a fitting for connecting pipelines in boosting rural water supply pipelines. It is usually used to connect pipelines with different diameters or materials to ensure firm and sealed pipeline connections. When connecting plastic pipelines, hot melt connection can be used for connection, and a hydraulic fixture can be used for pressurization during hot melt connection to ensure the quality and stability of the connection.

[0003] The existing hydraulic fixture for pipelines needs to connect both ends of the pipeline, and the connection position of the pipeline needs to be heated by hot melt for easy connection after docking. When the fixture is fixed at both ends of the pipeline, the pipeline is prone to deformation under the pressure of the external fixture during heating, which affects the connection quality of the pipeline. And clamping at a position far from the pipeline connection end is not convenient for controlling the precise docking of the pipeline mouth, thus being disadvantageous for the hot melt connection work of the pipeline. Content of the Utility Model

[0004] The utility model provides a pipeline connector for boosting rural water supply pipelines, which has the characteristic of solving the problem that the pipeline is prone to deformation when heated and then under pressure during hot melt.

[0005] The utility model provides the following technical solution: It includes a left support plate, a right support plate is arranged on one side of the left support plate, a left support frame and a right support frame are fixedly connected to the left support plate and the right support plate. A plurality of fixing rods are fixedly connected to one side of the left support frame, the fixing rods are slidably connected to the right support frame, a left clamping ring and a right clamping ring are slidably connected to the fixing rods. Driving telescopic rods for supporting the left clamping ring and the right clamping ring are fixedly connected to one side of the left support frame and the right support frame. Two limiting clamping rings are arranged between the left clamping ring and the right clamping ring, a sliding rod is fixedly connected to the outer wall of the limiting clamping ring, an adjusting rod is threadedly connected to one of the sliding rods, one end of the adjusting rod is rotatably connected to the other sliding rod, one of the limiting clamping rings is connected to the right clamping ring through a positioning rod, a threaded rod is rotatably connected to the left support frame, and a connecting block threadedly connected to the threaded rod is fixedly connected to the right support plate.

[0006] Wherein, a fixing block is fixedly connected to the left support plate, a motor is fixedly connected to one side of one of the fixing blocks, the driving end of the motor is fixedly connected to the threaded rod, a limiting rod is fixedly connected to the other fixing block, and the limiting rod is slidably connected to the left support frame.

[0007] Among them, a sliding hole matching the fixed rod is formed in the right support frame, a limiting block is fixedly connected to the right support plate, and a sliding groove matching the limiting block is formed at the bottom of the sliding rod.

[0008] Among them, a sliding plate is fixedly connected to the connection part between the left support plate and the right support plate, and a limiting groove matching the sliding plate is formed in the right support plate.

[0009] Among them, a rotating plate is fixedly connected to one end of the adjusting rod, and the rotating plate is rotatably connected to the sliding rod.

[0010] The beneficial effects of the utility model are as follows: while the outer wall of the pipeline can be supported by the left clamping ring and the right clamping ring, the connection part with one end of the pipeline can be made farther away. Cooperating with the driving telescopic rod can support the left clamping ring, so that the left clamping ring drives the pipeline to be pushed to thermally fuse the two sections of pipelines. At the same time, the connection part of the pipelines is limited by the limiting clamping ring, and the distance between the two limiting clamping rings can be adjusted by the sliding rod and the adjusting rod, ensuring that the limiting clamping ring is located on the outer wall of one end of the two sections of pipelines, and ensuring that the two sections of pipelines are horizontally corresponding for thermal fusion connection.

Detailed Embodiment

[0017] Please refer to Figures 1-4, the present utility model provides the following technical solutions: It includes a left support plate 1, a right support plate 11 is provided on one side of the left support plate 1, a left support frame 12 and a right support frame 13 are fixedly connected to the left support plate 1 and the right support plate 11, several fixing rods 2 are fixedly connected to one side of the left support frame 12, the fixing rods 2 are slidably connected to the right support frame 13, a left clamping ring 21 and a right clamping ring 22 are slidably connected to the fixing rods 2, driving telescopic rods 4 for supporting the left clamping ring 21 and the right clamping ring 22 are fixedly connected to one side of the left support frame 12 and the right support frame 13 respectively, two limiting clamping rings 23 are provided between the left clamping ring 21 and the right clamping ring 22, a sliding rod 24 is fixedly connected to the outer wall of the limiting clamping ring 23, an adjusting rod 25 is threadedly connected to one of the sliding rods 24, one end of the adjusting rod 25 is rotatably connected to the other sliding rod 24, one of the limiting clamping rings 23 is connected to the right clamping ring 22 through a positioning rod 221, a threaded rod 32 is rotatably connected to the left support frame 12, and a connecting block 33 threadedly connected to the threaded rod 32 is fixedly connected to the right support plate 11.

[0018] In this implementation: The left support plate 1 is the carrier of the bearing device. The left support frame 12 fixedly connected to the left support plate 1 is used to support the bottom of a section of pipeline to be connected. The outer wall of the pipeline is supported by the inner wall of the left support frame 12. The right support plate 11 arranged on one side of the left support plate 1 is used to support another section of the connected pipeline. The outer wall of the pipeline is supported by the right support frame 13 fixedly connected to the right support plate 11. The left support plate 1 is slidably connected to the right support plate 11, and the left support frame 12 and the right support frame 13 are matched to ensure that the pipeline remains horizontal when being supported. A number of fixed rods 2 fixedly connected to one side of the left support frame 12 are slidably connected to the right support frame 13. While the left support frame 12 and the right support frame 13 are horizontally corresponding, the left clamping ring 21 and the right clamping ring 22 slidably connected to the fixed rod 2 can be penetrated by the fixed rod 2 and be limited. The left clamping ring 21 and the right clamping ring 22 can be limited by the fixed rod 2 and be horizontally corresponding to the left support frame 12 and the right support frame 13. At the same time, the fixed rod 2 is slidably connected to them, so that the positions of the left clamping ring 21 and the right clamping ring 22 on the fixed rod 2 can be adjusted. When the pipeline is supported by hot melting, at this time, the left clamping ring 21 and the right clamping ring 22 are supported and fixed at a position far from the connection of the two sections of the pipeline. The pipeline is fixed by the left clamping ring 21 and the right clamping ring 22, and the hot melting heating area at one end of the pipeline is avoided. Thus, after the pipeline is heated, the left clamping ring 21 and the right clamping ring 22 do not need to provide a large frictional force to the pipeline. In order to facilitate the driving telescopic rod 4 fixedly connected to the left support frame 12 and the right support frame 13 to provide a thrust to it, the right clamping ring 22 and the left clamping ring 21 clamp the pipeline to displace so that one end of it generates adhesion after hot melting, thereby connecting it. At the same time, the left clamping ring 21 and the right clamping ring 22 are far from the opening position at one end of the pipeline and will not cause the pipeline to be deformed by its pressure. At the same time, in order to ensure that the two sections of the pipeline can be horizontally corresponding, at this time, two limit clamping rings 23 can be respectively located at the opening of one end of the pipeline. The inner wall of the limit clamping ring 23 is matched with the inner wall of the pipeline, so that it will not exert pressure on the outer wall of the pipeline. One end of the limit clamping ring 23 is fixed on the right clamping ring 22 so that its position can be fixed. The distance between the limit clamping rings 23 can be adjusted by screwing the adjusting rod 25 and the sliding rod 24, so that the position of the sliding rod 24 on the upper adjusting rod 25 can be adjusted, and the distance between the limit clamping rings 23 can be adjusted to make the limit clamping rings 23 in a position that does not affect hot melting heating and limit the two ends of the pipeline. When the pipeline needs to be connected, the driving telescopic rod 4 that supports the left clamping ring 21 on the left side supports the pipeline, while the positions of the driving telescopic rod 4 and the right clamping ring 22 on the right side remain unchanged, so that the right clamping ring 22 supports and fixes the pipeline on the right side. When the left pipeline is pushed to be butted with it, its hot melting connection can be achieved. Thus, the device can ensure that when the pipeline is hot melting connected, while preventing the connection of the two sections of the pipeline from being deformed by pressure, it can ensure that the two sections of the pipeline are horizontally corresponding under the limitation of the limit clamping rings 23. The distance between the left support plate 1 and the right support plate 11 can be adjusted by rotating the threaded rod 32 rotatably connected to the left support frame 12,Adjust the position of the threaded rod 32 on the connecting block 33, so as to adjust the positions of the left support frame 12 and the left support plate 1. Drive the telescopic rod 4 to be fixed on the left support frame 12, and the drive telescopic rod 4 is fixedly connected with the left snap ring 21, so that the position where the left snap ring 21 supports on the pipeline can be adjusted by adjusting the positions of the left support frame 12 and the left support plate 1, so as to facilitate the control of the position of the left snap ring 21 and ensure that it will not be misaligned with the position where the pipeline is prone to deformation due to heat.

[0019] A fixing block 3 is fixedly connected to the left support plate 1. One side of one of the fixing blocks 3 is fixedly connected with a motor 31, and the driving end of the motor 31 is fixedly connected with the threaded rod 32. A limiting rod 321 is fixedly connected to the other fixing block 3, and the limiting rod 321 is slidably connected with the left support frame 12; the fixing block 3 fixedly connected to the left support plate 1 is used to provide an installation surface for the motor 31. Through the driving end of the motor 31 being fixedly connected with the threaded rod 32, it can drive the threaded rod 32 to rotate and adjust its position on the connecting block 33, so as to adjust the positions of the left support plate 1 and the left support frame 12, so that the position of the left snap ring 21 can be adjusted, facilitating the adjustment of the left snap ring 21 to a position farther from the heat-softening area at one end of the pipeline to protect the pipeline. The limiting rod 321 is used to ensure the horizontal displacement of the left support plate 1 when the motor 31 drives the threaded rod 32 to rotate and adjust the position of the threaded rod 32 on the connecting block 33, and can be slidably limited on the connecting block 33 fixedly connected to another right support plate 11 through the limiting rod 321.

[0020] A sliding hole 131 matching the fixing rod 2 is provided on the right support frame 13, and a limiting block 26 is fixedly connected to the right support plate 11. A sliding groove 27 matching the limiting block 26 is provided at the bottom of the sliding rod 24; the sliding hole 131 provided on the right support frame 13 is used to enable the fixing rod 2 to be slidably connected with the right support frame 13, so that after the position of the left support frame 12 is adjusted by the drive of the motor 31, the fixing rod 2 can be adjusted synchronously with it, and the fixing rod 2 has a certain length, so that it slides on the inner wall of the sliding hole 131 to ensure that it will not be separated from the right support frame 13. The limiting block 26 is used to limit the left and right sliding displacement of the sliding rod 24. By limiting the limiting block 26 in the sliding groove 27, the displacement of the sliding rod 24 is limited to ensure the horizontal displacement of the sliding rod 24 and the limiting snap ring 23.

[0021] A sliding plate 14 is fixedly connected to the connection between the left support plate 1 and the right support plate 11, and a limiting groove 141 matching the sliding plate 14 is provided on the right support plate 11; the sliding plate 14 fixedly connected to the connection between the left support plate 1 and the right support plate 11 is used to penetrate into the limiting groove 141 provided on the right support plate 11, so that the sliding plate 14 slides on the inner wall of the limiting groove 141, enabling the left support plate 1 to slide at one end of the right support plate 11 to ensure that after the position of the left support plate 1 is adjusted, the left support plate 1 can be horizontally corresponding to the right support plate 11.

[0022] One end of the adjusting rod 25 is fixedly connected with a rotating plate 251, and the rotating plate 251 is rotatably connected with the sliding rod 24; the rotating plate 251 fixedly connected to one end of the adjusting rod 25 is rotatably connected with the sliding rod 24, so that when the adjusting rod 25 is threadedly connected with one of the sliding rods 24, one end thereof can be rotatably connected with the other sliding rod 24, so that the distance between the sliding rods 24 can be adjusted, thereby adjusting the distance between the limiting snap rings 23.

[0023] The working principle and usage process of the present utility model: By rotating the threaded rod 32, the position of the threaded rod 32 on the connecting block 33 can be adjusted, so that the positions of the left support plate 1 and the left support frame 12 can be adjusted, thereby adjusting the position of the left snap ring 21. At this time, the left snap ring 21 and the right snap ring 22 are supported and fixed at a position farther from the connection of the two sections of the pipeline. The pipeline is fixed by the left snap ring 21 and the right snap ring 22, and the heat fusion heating area at one end of the pipeline is avoided, so as to prevent the pipeline from deforming under pressure after being heated. At the same time, in order to ensure that the two sections of the pipeline can be horizontally corresponding, at this time, the two limiting snap rings 23 can be respectively located at the openings at one end of the pipeline. Since the inner wall of the limiting snap ring 23 matches the inner wall of the pipeline, it will not apply pressure to the outer wall of the pipeline. One end of the limiting snap ring 23 is fixed on the right snap ring 22, so that its position can be fixed. At this time, the driving telescopic rod 4 that supports the left snap ring 21 on the left side supports the pipeline, while the positions of the driving telescopic rod 4 and the right snap ring 22 on the right side remain unchanged, so that the right snap ring 22 supports and fixes the pipeline on the right side. When the left pipeline is pushed to be butted with it, it can be heat-fused connected, so that the device can ensure that when the pipeline is heat-fused connected, while preventing the connection of the two sections of the pipeline from deforming under pressure, it can ensure that the two sections of the pipeline are horizontally corresponding under the limitation of the limiting snap ring 23.
