Description

Technical Field

[0001] The utility model belongs to the field of pipeline connectors, and in particular relates to a pressure pipeline connector structure. Background Art

[0002] Pressure piping refers to all pipelines that are subject to internal or external pressure, regardless of the medium inside the pipe. Pressure piping is a part of a pipeline that is used to transport, distribute, mix, separate, discharge, meter, control and stop the flow of fluids. It is an assembly consisting of pipes, pipe fittings, flanges, bolted connections, gaskets, valves, other components or pressure-bearing parts and supports.

[0003] Chinese utility model patent CN219549840U discloses a pressure pipe connector, including a pressure pipe, a connection assembly and an anti-drop assembly, wherein the connection assembly includes a connecting pipe for sealingly connecting the pressure pipes on both sides, and sockets extending inward at both ends of the connecting pipe to match the pipe walls of the pressure pipes on both sides. The pressure pipe connector described in the utility model has sockets matching the pipe walls of the pressure pipe opened at both ends of the connecting pipe, a sealing gasket installed in the socket, and an inner sealing wall reserved at the inner end of the socket, which can ensure the sealing between the connecting pipe and the pressure pipes on both sides through an embedded connection to the pressure pipe, and the clamps locked in the concave ring on the outer side of the connecting pipe can also press the two sides of the connecting pipe to the upper end of the pressure pipe;

[0004] The above design uses connecting components and anti-detachment components to stably connect the pipes and enhance the stability of the equipment when in use. However, the pipe connectors of this design are not equipped with safety protection mechanisms when in use. Some inspectors need to disassemble the connectors and disconnect the pipes on both sides when inspecting the pipes. Once water is flowing inside the pipes, easily disassembling the pipes and connectors can easily pose a threat to the safety of the maintenance personnel themselves and affect the overall work quality.

The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0029] Depend on Figure 1 , Figure 2 and Figure 3 As shown, a pressure pipe connector structure comprises a connecting body 1, an upper fixing frame 2 and a lower fixing frame 3, the upper fixing frame 2 is symmetrically arranged on the outside of the connecting body 1, the lower fixing frame 3 is rotatably installed on the bottom end of the upper fixing frame 2, a connecting pipe 4 is slidably installed on the side of the connecting body 1, a limiting mechanism 5 is symmetrically fixedly installed on the inner wall of the connecting body 1, the limiting mechanism 5 comprises an outer shell 51, a movable groove 52, a pressure plate 53, a spring 54, a block 55 and a groove 56, the outer shell 51 is fixedly installed on the inner wall of the connecting body 1, a movable groove 52 is opened inside the outer shell 51, the pressure plate 53 is slidably installed inside the movable groove 52, the block 55 is fixedly installed on the top of the pressure plate 53, the spring 54 is symmetrically arranged inside the movable groove 52, a groove 56 is opened inside the connecting pipe 4, the groove 56 is slidably connected to the block 55, the upper fixing frame 2 and the lower fixing frame 3 are jointly fixedly installed with a clamping mechanism 6 on the side, and an anti-slip mechanism 7 is fixedly installed on the side of the upper fixing frame 2 and the lower fixing frame 3.

[0030] When in use, the connecting body 1 is placed at the target position, and then the connecting pipe 4 on the side is inserted into the connecting body 1. The upper fixing frame 2 and the lower fixing frame 3 are squeezed by using the clamping mechanism 6, so that the upper fixing frame 2 and the lower fixing frame 3 fix the connecting body 1 and the connecting pipe 4 at the bottom. In addition, due to the use of the anti-slip mechanism 7, the stability of the connection between the upper fixing frame 2, the lower fixing frame 3 and the connecting body 1 can be enhanced. In subsequent use, the impact force and pressure of the water flow are used to automatically trigger the limiting mechanism 5, and the pressure plate 53 automatically shrinks into the moving groove 52 under the action of pressure, so that the block 55 moves to the top, so that the block 55 enters the card groove 56 inside the connecting pipe 4, and limits the connecting pipe 4. It is ensured that when the connecting body 1 and the connecting pipe 4 are working, the connecting pipe 4 cannot be disconnected from the connecting body 1, thereby ensuring the safety of the connecting piece when in use, thereby improving the working quality of the equipment itself.

[0031] By the attached Figure 4 As shown, in this embodiment, the pressure plate 53 is trapezoidal in shape as a whole. During use, no matter how the direction of the water flow changes, the position of the pressure plate 53 can be squeezed so that the pressure plate 53 automatically enters the movable groove 52.

[0032] By the attached Figure 4 As shown, in this embodiment, a sealing gasket is provided at the connection between the connecting body 1 and the connecting pipe 4 to strengthen the sealing of the connection between the connecting body 1 and the connecting pipe 4 during use and prevent water leakage inside the pipe.

[0033] By the attached Figure 5 As shown, in this embodiment, the clamping mechanism 6 includes a side plate 61, a steering rod 62, an extrusion screw 63 and an extrusion end 64. The side plate 61 is fixedly installed on the side of the lower fixed frame 3, the steering rod 62 is rotatably installed inside the side plate 61, the extrusion screw 63 is fixedly installed on the side of the steering rod 62, and the extrusion end 64 is threadedly installed on the outside of the extrusion screw 63.

[0034] During use, the upper fixing frame 2 and the lower fixing frame 3 are placed at the connection between the connecting body 1 and the connecting pipe 4. By using the turning rod 62, the extrusion screw 63 is turned into the component on the side of the upper fixing frame 2, and then the extrusion end 64 is rotated so that the extrusion end 64, in cooperation with the extrusion screw 63, continuously moves downward to squeeze the upper fixing frame 2 and the lower fixing frame 3, thereby completing the locking of the component position.

[0035] By the attached Figure 5 As shown, in this embodiment, an extrusion block is fixedly installed on the side of the upper fixing frame 2, and an installation groove is opened inside the extrusion block. During use, the installation of the extrusion block facilitates the extrusion screw 63 to be turned into the extrusion block, and the subsequent extrusion end 64 can complete the combination and connection of the components by extruding the extrusion block.

[0036] By the attached Figure 6 As shown, in this embodiment, the anti-slip mechanism 7 includes a retaining ring 71, a positioning ring 72 and a limiting groove 73. The retaining ring 71 is symmetrically fixedly installed on the outer wall of the connecting body 1, and the positioning ring 72 is fixedly installed on the sides of the upper fixing frame 2 and the lower fixing frame 3. A limiting groove 73 is provided inside the positioning ring 72, and the limiting groove 73 is slidably connected to the retaining ring 71.

[0037] During use, the clamping mechanism 6 is used to reduce the distance between the upper fixing frame 2 and the lower fixing frame 3. During the adjustment process, the positioning ring 72 can be sleeved on the outside of the retaining ring 71 so that the retaining ring 71 enters the limiting groove 73, thereby further strengthening the connection between the connecting body 1 and the connecting pipe 4, ensuring the stability of the connecting body 1 during use, and preventing the connecting body 1 from loosening from the connecting pipe 4 due to excessive water pressure inside the pipe.

[0038] By the attached Figure 6 As shown, in this embodiment, clamping blocks are fixedly installed on the inner walls of the upper fixing frame 2 and the lower fixing frame 3, which strengthen the friction force when the upper fixing frame 2 and the lower fixing frame 3 contact the outer wall of the connecting pipe 4 during use, ensuring the stability of the fixing effect of the components themselves.

[0039] By the attached Figure 1 As shown, in this embodiment, a slot is provided inside the connection body 1 on the side of the connection pipe 4, which facilitates the connection body 1 and the connection pipe 4 to be connected during use, thus providing convenience for the use of subsequent components.
