Description

Technical Field

[0001] The utility model relates to the technical field of oil drilling instrument machinery, in particular to a rotary buckle type fixed connector used for M30 line testing. Background Art

[0002] The M30 metal ring of the existing oil drilling instrument plays a role in signal transmission. The test connector of the M30 metal ring is usually bound to the cylindrical instrument through two cylindrical toolings with a diameter of about 2 cm through locking cloth buckles, and then connected for testing.

[0003] In the process of implementing the technical method of the embodiment of the utility model, the inventors of this application found that there are at least the following technical problems in the prior art:

[0004] The following technical problems are prone to occur during the use of cylindrical tooling:

[0005] (1) Difficult to operate: During installation, cylindrical instruments are generally placed on the ground. The bottom of the instrument is in direct contact with the ground with almost no gap between them. It is necessary to lift or pick up the instrument first, and then place tools such as wood or iron rods under the instrument to raise the instrument. Alternatively, it is necessary to dig a hole under the instrument to leave space for the locking tape to wrap around the instrument. Therefore, it is difficult to fix the locking tape that fixes the test connector on the instrument.

[0006] (2) Difficulty in installation and debugging: During the installation and debugging process, it is necessary to adjust the mobile test connector along the radial direction of the cylindrical section of the cylindrical instrument, and also to adjust the mobile test connector along the long axis direction of the cylindrical instrument, making it difficult to determine the installation position.

[0007] (3) Low connection efficiency: After the test connector is fixed on the cylindrical instrument, during the process of plugging and unplugging the connecting wire, since the conductive connecting wire is in point contact with the metal, it is easy to cause problems such as poor contact and collapse, and constant adjustment is required.

[0008] (4) Not conducive to operation: Due to the relatively low installation position, the operator needs to keep bending or kneeling for a long time during the debugging period. Considering the harsh environment of on-site operations, it is not conducive to the operator to work for a long time.

[0009] In summary, the existing M30 metal ring test connector cannot meet actual usage requirements. Utility Model Content
