The utility model is characterized by convenient installation, time saving and labor saving.
Description
Technical field:
The utility model relates to rig drill steel joint used in the geological exploration field, especially drill steel snap joint.
Background technology:
In geological prospecting, drill drilling is an important means wherein, generally be to utilize rig to carry out strata drilling, because the ground layer depth that need creep into, thereby used drill steel must one one couple together and could realize drilling well needs, at present used drill steel joint makes its installation inconvenience because of its reasons in structure, and is time-consuming, require great effort, cause exploration long in time limit, inefficiency.
The utility model content:
In order to overcome existing drill steel joint deficiency inconvenient and time-consuming, that require great effort is installed, the utility model provides a kind of drill steel snap joint, this joint have easy for installation and save time, the labour-saving characteristics.
The technical solution of the utility model is: this drill steel snap joint comprises fittings body, the fittings body cunning is stuck on the drill steel, the fittings body upper surface along the circumferential direction evenly has some circular-arc straight troughs that communicate and tongue-and-groove and has boss at the tongue-and-groove end, the tenon that some bands convex edge is arranged between adjacent straight trough and boss, two fittings bodies block mutually and are one.
Above-mentioned straight trough, tongue-and-groove, boss and tenon are two.
The utlity model has following beneficial effect: owing to take fittings body upper surface in the such scheme along the circumferential direction evenly to have some circular-arc straight troughs that communicate and tongue-and-groove and have boss at the tongue-and-groove end, the tenon that some bands convex edge is arranged between adjacent straight trough and boss, during two fittings body butt joints, tenon can enter tongue-and-groove along straight trough, the swivel joint body is to the boss place, two fittings bodies block tightly mutually and are one, and are easy for installation, save time, laborsaving.
