Description

Technical Field

[0001] The utility model relates to the technical field of heat supply pipe network connection equipment, and specifically to a modular assembled pipeline connection structure. Background Technique

[0002] In a heat supply pipe network, pipeline connection is a key link. Traditional pipeline connection methods often have problems such as complex installation, poor sealing performance, and inconvenient maintenance. In order to improve the installation efficiency and operation reliability of the heat supply pipe network, a new pipeline connection structure is needed that can achieve rapid assembly and disassembly.

[0003] The utility model patent with the authorization announcement number CN218063784U discloses a pipeline connection structure for HVAC construction, including an inner pipe and an outer pipe, and the inner pipe is arranged inside the outer pipe. A connecting piece is arranged on the outer side of the middle part of the inner pipe, and the inner pipe and the outer pipe are fixedly connected through the connecting piece. An elastic ring is embedded on the inner side wall of the outer pipe, and the elastic ring is fixedly welded to the outer pipe. A second sealing ring is embedded on the inner side of the elastic ring. A hoop is arranged on the outer side of the elastic ring. A tightening piece is arranged on the top of the hoop, and both ends of the hoop are connected to the tightening piece.

[0004] Although in this technical solution, by inserting the first pipe body and the second pipe body into the gap formed between the inner pipe and the outer pipe, and then rotating the tightening piece to wind up both ends of the hoop, the hoop tightens the elastic ring, causing the elastic ring to squeeze the second sealing ring. After connecting the pipe fittings with this structure, the sealing ring at the connection of the pipe fittings is subjected to extrusion reinforcement treatment, and the sealing performance is good. However, when replacing the damaged pipeline under this technical solution, the heating circulation of the corresponding pipeline cannot be shut off. At the same time, after the pipeline is connected, the pipeline is not fixed, so that the pipeline rotates and falls off. In view of this, we propose a modular assembled pipeline connection structure. Content of the Utility Model

[0026] The following further elaborates on this application in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. Additionally, it should be noted that for ease of description, only the parts related to the utility model are shown in the drawings.

[0027] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will detail this application with reference to the accompanying drawings and embodiments.

[0028] Please refer to Figures 1 - 6 , a modular assembled pipeline connection structure, including a connection assembly 1 and pipelines 2 installed at both ends thereof. The connection assembly 1 includes a connector 11, and fixing members 12 are fixed to both ends of the connector 11 through a plurality of first locking bolts 13;

[0029] The connector 11 includes an adjusting block 111. An adjusting cavity 1113 is formed in the adjusting block 111. An intercepting block 113 is slidably connected in the adjusting cavity 1113. A threaded rod 114 is rotatably connected to the middle of the adjusting cavity 1113. The threaded rod 114 is threadedly connected to the intercepting block 113. Connection cylinders 112 adapted to the pipelines 2 are welded and fixed to the bottom ends of two opposite side walls of the adjusting block 111;

[0030] The fixing member 12 includes a semi-circular block 121. At both ends of the semi-circular block 121, symmetrically arranged fan-shaped rings 122 are hinged through hinge seats 1211 provided at the edges of the outer side walls thereof. The two fan-shaped rings 122 can be fixed through a second locking bolt 124 at one end away from the semi-circular block 121.

[0031] In this embodiment, a cylindrical block 1111 is welded and fixed at the center of the top surface of the adjusting block 111. An annular groove 1112 is formed in the cylindrical block 1111; the cylindrical block 1111 is used to install the threaded rod 114.

[0032] Furthermore, the top end of the threaded rod 114 extends out of the adjusting block 111 and is welded and fixed with a handle 1141. A limiting ring 1142 adapted to the size of the annular groove 1112 is integrally formed on the upper end of the outer side wall of the threaded rod 114; the handle 1141 facilitates the rotation of the threaded rod 114, and the adapted limiting ring 1142 and the annular groove 1112 prevent the threaded rod 114 from moving up and down during rotation.

[0033] Secondly, a threaded hole 1131 adapted to the threaded rod 114 is formed at the center of the top surface of the intercepting block 113. The longitudinal cross-section of the intercepting block 113 is larger than the longitudinal cross-section of the middle hole of the connector 11; the adapted threaded hole 1131 enables the intercepting block 113 to slide up and down along the adjusting cavity 1113 when the threaded rod 114 rotates.

[0034] Furthermore, an external thread 21 is provided on the outer sidewall of the end of the pipe 2, and an internal thread 1121 adapted to the external thread 21 is provided on the inner sidewall of the connecting cylinder 112. A first fixed half-ring 1122 is welded and fixed at the edge of the outer sidewall of the connecting cylinder 112 close to the fixing member 12, and a second fixed half-ring 1212 is welded and fixed at the edge of the outer sidewall of the half-ring block 121 close to the connecting cylinder 112. A number of through holes adapted to the first locking bolt 13 are provided on both the first fixed half-ring 1122 and the second fixed half-ring 1212; the adapted external thread 21 and internal thread 1121 make the connection between the pipe 2 and the connecting member 11 tight, and the first fixed half-ring 1122 and the second fixed half-ring 1212 facilitate the assembly and disassembly of the fixing member 12 and the connecting member 11.

[0035] Secondly, when the intercepting block 113 slides to the topmost end of the adjustment cavity 1113, the central hole of the connecting member 11 is completely exposed. When the intercepting block 113 slides to the bottommost end of the adjustment cavity 1113, the intercepting block 113 completely blocks the central hole of the connecting member 11. The threaded section length of the threaded rod 114 is equal to the distance from the topmost end to the bottommost end of the adjustment cavity 1113; the design of the sliding position of the intercepting block 113 enables it to completely block the central hole of the connecting member 11, and the length design of the threaded rod 114 enables the intercepting block 113 to slide to the topmost end and the bottommost end of the adjustment cavity 1113 as it rotates.

[0036] Furthermore, an articulated convex block 1221 adapted to the articulated seat 1211 is integrally formed at one end of the sector ring 122 close to the half-ring block 121. The articulated seat 1211 and the articulated convex block 1221 are articulated by an articulated column 123. The half-ring block 121 and the two sector rings 122 form a complete ring, and the inner diameter of the ring is equal to the outer diameter of the pipe 2; the articulated column 123 enables the sector ring 122 to be articulated with the half-ring block 121, and the design of the inner diameter of the ring enables the fixing member 12 to firmly fix the pipe 2 and prevent it from rotating.

[0037] Working principle: When the modular assembled pipe connection structure of the present utility model is in use, the user first rotates the pipes 2 at both ends of the connection assembly 1 to threadedly connect them into the connecting cylinder 112, then fixes the fixing member 12 on the connecting cylinder 112 through the first locking bolt 13, closes the two opposite sector rings 122, and then fixes them through the second locking bolt 124, thereby fixing the pipe 2. When the pipe 2 is damaged, the threaded rod 114 is rotated through the handle 1141, so that the intercepting block 113 moves downward along the adjustment cavity 1113 to block the central hole of the connecting member 11, thereby cutting off the heating circulation and repairing the damaged pipe 2.

[0038] The above description is only a preferred embodiment of the present application and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept of the utility model. For example, the technical solutions formed by the mutual replacement of the above features and the technical features disclosed in the present application but not limited to having similar functions.
