Description

Technical Field

[0001] This utility model relates to the field of oil and gas pipeline equipment technology, and specifically discloses an easy-to-disassemble connection structure for oil and gas pipeline instruments. Background Technology

[0002] The easy-to-install and disassemble connection structure for instruments is a functional design used in oil and gas pipeline equipment to optimize instrument maintenance operations. Its core function is to enable the rapid installation, disassembly and replacement of instruments such as pressure gauges and flow meters through standardized interfaces and positioning mechanisms.

[0003] If the pipeline is not properly treated during the disassembly of the instrument, leaks may occur. Furthermore, if the connection structure is too simple, the connectors may easily separate under vibration or pressure during use. Therefore, an easy-to-disassemble connection structure for oil and gas pipeline instruments is needed to solve this problem. Utility Model Content

[0004] This utility model proposes an easy-to-disassemble connection structure for oil and gas pipeline instruments. During the rotation of the sleeve, the extension frame drives the linkage block to rotate, which in turn pushes the hollow tube to rotate the connecting pipe. This aligns the rectangular groove of the connecting pipe with the plugging block, thereby blocking the connecting pipe. This achieves the purpose of locking the device and pipeline interface before disassembly, solving the problem of oil and gas pipeline leakage that may occur during disassembly.

[0005] This utility model is implemented as follows: an easy-to-disassemble connection structure for oil and gas pipeline instruments includes a limiting plate. A threaded rod is fixedly connected to the inner wall of the limiting plate. A partition structure is fixedly connected to the inner wall of the threaded rod. A connecting pipe is rotatably connected to the outer surface of the partition structure. A hollow tube is fixedly connected to the inner wall of the connecting pipe. A linkage block is snapped into the inner surface of the hollow tube. An extension frame is fixedly connected to the outer arc surface of the linkage block. A blocking sleeve is fixedly connected to the outer arc surface of the extension frame. A partition structure is slidably connected to the outer surface of the blocking sleeve. A storage sleeve is slidably connected to the outer surface of the blocking sleeve. A limiting plate is fixedly connected to the lower end of the storage sleeve. A limiting block is slidably connected to the inner surface of the storage sleeve. A height adjustment ring is fixedly connected to the upper surface of the limiting block. A guide column is slidably connected to the inner surface of the height adjustment ring. An instrument tube is fixedly connected to the outer surface of the guide column. A blocking sleeve is fixedly connected to the lower end of the instrument tube.

[0006] As a preferred embodiment of the easy-to-disassemble connection structure for oil and gas pipeline instruments of this utility model, the separation structure includes an isolation pipe, a plugging block, and a surge-blocking pipe. A screw groove rod is fixedly connected to the outer circumference of the isolation pipe, a plugging block is fixedly connected to the lower end of the isolation pipe, a surge-blocking pipe is fixedly connected to the inner wall of the isolation pipe, and a connecting pipe is rotatably connected to the lower end of the surge-blocking pipe.

[0007] As a preferred embodiment of the easy-to-disassemble connection structure for oil and gas pipeline instruments of this utility model, the isolation pipe is a circular pipe with an annular groove at the upper end and a blocking sleeve slidably connected to the inner surface of the annular groove.

[0008] As a preferred embodiment of the easy-to-disassemble connection structure for oil and gas pipeline instruments of this utility model, the connecting pipe is a circular pile, and the upper end of the connecting pipe is provided with a circular groove. The inner wall of the circular groove is provided with two rectangular grooves that extend to the outer surface of the connecting pipe. The length and width of the rectangular grooves are both smaller than the length and width of the plugging block.

[0009] As a preferred embodiment of the easy-to-disassemble connection structure for oil and gas pipeline instruments of this utility model, the hollow tube is a circular rod with a cross groove at the upper end and a connecting block engaged on the inner surface of the cross groove.

[0010] As a preferred embodiment of the easy-to-disassemble connection structure for oil and gas pipeline instruments of this utility model, the isolation sleeve is an annular block, and two rectangular keys are provided on the outer arc surface of the isolation sleeve. A storage sleeve is slidably connected to the outer surface of the rectangular keys, and a rubber ring is provided at the lower end of the isolation sleeve.

[0011] As a preferred embodiment of the easy-to-disassemble connection structure for oil and gas pipeline instruments of this utility model, the storage sleeve is a circular sleeve with an annular groove on the inner wall of the circular sleeve, two rectangular grooves extending to the upper surface of the storage sleeve on the top inner wall of the annular groove, and two square grooves on the upper surface of the storage sleeve.

[0012] The beneficial effects of this utility model are:

[0013] 1. The easy-to-disassemble connection structure of the oil and gas pipeline instrument, through the rotation of the sleeve, drives the connecting block to rotate through the extension frame, so that the connecting block pushes the hollow tube to rotate the connecting pipe, so that the rectangular groove of the connecting pipe is aligned with the plugging block, thereby blocking the connecting pipe. This achieves the purpose of locking the device and pipeline interface before disassembly, and solves the problem that disassembly may lead to oil and gas pipeline leakage.

[0014] 2. The easy-to-disassemble connection structure of the oil and gas pipeline instrument allows for disassembly by pulling up the height adjustment ring, which causes the height adjustment ring to lift the limit block, thus disengaging the limit block from the storage sleeve. Then, the instrument tube can be rotated 90 degrees and pulled upward to disassemble the structure. This achieves the purpose of locking the device during use and solves the problem that the easy-to-disassemble connection parts are prone to separation under vibration or pressure.
