Abstract
An adapter coupling comprises a cylindrical body. One end of the cylindrical body is provided with an external thread connection portion, the outer diameter of the external thread connection portion is less than the outer diameter of the cylindrical body, a plurality of blocking pieces are symmetrically arranged on the end face of the external thread connection portion with the diameter of the end face serving as the central line, and the blocking pieces extend in the axial direction of the cylindrical body. The adapter coupling can effectively avoid looseness and abrasion at the connecting position of the adapter coupling and a locking coupling, and enhances the safety and the reliability of geological drilling and coring.
Description
Technical field
The present invention relates to used for geological prospecting boring tool, be specifically related to the bullet block head in coring instrument.
Background technology
Playing block head is one of critical component in probing coring instrument outer tube structure, its one end jointed rod, and the other end bullet card chamber that is threaded, drives reamer, outer tube rotation, makes bit carry out drilling operation.Existing bullet block head is connected with the internal thread of bullet card chamber by the external screw thread of end, when bullet block head is connected with bullet clamp, play the certain gap of common maintenance between clamp and the end face of bullet block head, in the course of the work, play the threaded joints of block head and bullet card chamber often because stressed wearing and tearing are become flexible, cause playing in the course of the work block head and drilling tool and form and relatively rotate, the wearing and tearing that make to play block head are more serious.
Summary of the invention
The applicant improves for above-mentioned shortcoming of the prior art, provides a kind of and can effectively avoid bullet block heads loosening and wearing and tearing.
Technical scheme of the present invention is as follows:
Play block head, comprise cylindric body, one end of cylindric body is provided with external screw thread connecting portion, the external diameter of external screw thread connecting portion is less than the external diameter of cylindric body, on the end face of described external screw thread connecting portion, centered by its end face diameter, line is arranged with a plurality of catch, and described catch extends axially along cylindric body.
Its further technical scheme is:
Described catch is circular-arc, and the concave surface of a plurality of catch is relative.
On the end face of described external screw thread connecting portion, be arranged with two catch.
Technique effect of the present invention:
The present invention is by the setting of a plurality of catch on external screw thread connecting portion, when carrying out drilling operation, catch is just in time connected on the bullet clamp of drilling tool, outside retaining the function of original bullet block head and bullet card chamber, on the one hand, guaranteed to play block head with outside being threaded of bullet card chamber, also by playing the butt positioning action of clamp and catch, improved the connection reliability that plays block head and drilling tool outer tube, avoided the relatively rotating between block head and drill bit of being hit by a bullet of working, can effectively avoid playing the loosening and wearing and tearing of block head, strengthened the security reliability of geology coring, on the other hand, the inner tube assembly of the drilling tool play that can not make progress in the time of can guaranteeing work.
Accompanying drawing explanation
Fig. 1 is the perspective view of existing bullet block head.
Fig. 2 is the perspective view of bullet block head of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
See Fig. 1, Fig. 1 is the structural representation of existing bullet block head, and it comprises cylindric body 1, and one end of cylindric body 1 is provided with external screw thread connecting portion 2.
For fear of playing the loosening of block head and bullet card chamber connection of thread, cause the wearing and tearing that play block head, the present invention improves playing block head, see Fig. 2, bullet block head of the present invention comprises cylindric body 1, one end of cylindric body 1 is provided with external screw thread connecting portion 2, the external diameter of external screw thread connecting portion 2 is less than the external diameter of cylindric body 1, and on the end face of described external screw thread connecting portion 2, centered by its end face diameter, line is arranged with a plurality of catch 3, described catch 3 extending axially along cylindric body 1.
Particularly, described catch 3 is circular-arc, and the concave surface of a plurality of catch 3 is relative.
Preferably, consistent with the quantity of the bullet clamp of drilling tool, on the end face of described external screw thread connecting portion 2, be arranged with two catch 3.
During assembling drilling tool, bullet block head of the present invention and bullet card chamber are threaded connection, and it is indoor that the external screw thread connecting portion 2 of bullet block head and catch 3 stretch into bullet card, it is indoor that two bullet clamp (not shown)s in drilling tool are close to bullet card when softened state, and while strutting two play clamp just in time play block head below and between the two, there is vertical gap, by the setting of a plurality of catch on external screw thread connecting portion 2, when assembling drilling tool, catch 3 is just in time connected on the bullet clamp of drilling tool, now the positioning step coordinating with catch 3 can also be preferably set on outside on the bullet clamp of drilling tool, outside retaining the function of original bullet block head and bullet card chamber, on the one hand, the setting of catch 3, guaranteed to play block head with outside being threaded of bullet card chamber, also by playing the positioning step of clamp and the positioning action of catch 3, improved the connection reliability that plays block head and drilling tool outer tube, avoided the relatively rotating between block head and drill bit of being hit by a bullet of working, can effectively avoid playing the loosening and wearing and tearing of block head, strengthened the security reliability of geology coring, on the other hand, the inner tube assembly of the drilling tool play that can not make progress in the time of can guaranteeing work.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
