Description
Technical field
The utility model belongs to petroleum instrument field, the in particular to anti-drop device under rotation vibration.
Background technique
In recent years, it with well logging, the continuous research and development of amount well technology and update, is got over using the specification of instrument
Come more tend to miniaturization, lighting, this results in its structural member smaller and smaller, installation reserved space it is smaller and smaller, also therefore,
Connector can operating space be small, the high important requirement as connection structure of connection reliability.
Summary of the invention
The purpose of this utility model is that solve the deficiencies in the prior art, and a kind of bolt-type disconnecting prevention structure is provided.
The new technical solution of the utility model is: a kind of bolt-type disconnecting prevention structure, including connector A, connector B, pin block
And jackscrew is positioned, it is machined with installation position on the connector A, connector B, the installation position inner wall are installed in installation position
Two sides are equipped with positioning groove, and the pin block end is withstood in positioning groove；It is machined with location hole on the connector B, and
Positioning hole is equipped with positioning jackscrew, and the top connector B is equipped with pin block mounting groove, is equipped with pin in pin block mounting groove
Block, the pin block mounting groove are connected to location hole lower part.
The location hole is threadedly coupled with positioning jackscrew.
The pin block is 2 pieces.
The pin block is polyether-ether-ketone.
The positioning jackscrew is polyether-ether-ketone.
The utility model has the following beneficial effects: pin block uses high-strength material in the utility model, guarantee bonding strength；It is fixed
Position jackscrew limits the position of pin block, prevents connector from loosening, and guarantees the reliability of connection, while saving space, being easy dismounting.
