Abstract
The invention relates to an elastic clip chamber structure for drilling tool clamping. The elastic clip chamber structure comprises an elastic clip chamber. The elastic clip chamber is of a tubular structure and is provided with a center through hole. One end of the elastic clip chamber is provided with internal threads, the other end of the elastic clip chamber is provided with external threads, the middle side wall of the through hole in the elastic clip chamber is provided with a convex ring, the inner diameter of the convex ring is smaller than that of the through hole, and a drilling tool is connected in the convex ring in a clamped mode. According to the elastic clip chamber structure, the convex ring replaces a traditional seat ring, due to the fact that the convex ring and the elastic clip chamber are integrated, compared with a split structure of the seat ring and the elastic clip chamber, it is avoided that misplacement of the drilling tool occurs when a drill rod rotates, the accuracy and stability of connection of the drilling tool and the elastic clip are improved, and work reliability of the drill rod is improved.
Description
Technical field
The present invention relates to geological prospecting apparatus field, particularly relate to the drilling rod of rig.
Background technology
Drilling rod is the critical component in rig, and its end connects drilling tool by bullet card room.In prior art, as shown in Figure 1, bullet card room 1 is tubular structure, and its end is with internal thread, and the root of internal thread is provided with seat ring 2, and the internal diameter of seat ring 2 is less than the diameter of the through hole 12 of bullet card room 1, for clamping drilling tool.The shortcoming that the bullet card room of this structure exists is: bullet card room 1 and seat ring 2 are Split type structure, and during drilling rod High Rotation Speed, seat ring 2 easily misplaces, and easily blocks drilling tool, and the connection precision of itself and drilling tool is not high yet, and stability and firmness are also inadequate.
Summary of the invention
The shortcoming that the applicant exists for above-mentioned prior art, carries out studying and improving, and provides a kind of bullet card cell structure for drilling tool clamping, solves the problem of dislocation, bit freezing tool, and improves connection precision and stability.
The technical solution adopted in the present invention is as follows:
A kind of bullet card cell structure for drilling tool clamping, comprise bullet card room, bullet card room is tubular structure and with central through hole, one end of bullet card room is with internal thread, the other end is with external screw thread, the medial side cornice of the through hole of described bullet card room has bulge loop, and the internal diameter of described bulge loop is less than the diameter of described through hole, clamping drilling tool in bulge loop.
Beneficial effect of the present invention is as follows:
The present invention substitutes traditional seat ring by bulge loop, because bulge loop and bullet card room are structure as a whole, compare the Split type structure of seat ring and bullet card room, avoid when drilling rod rotates in the inconsistent phenomenon of drilling tool, and improve the precision and stability that are connected with drilling tool, improve the reliability of drilling rod work.
Accompanying drawing explanation
Fig. 1 is the three-dimensional structure diagram of existing bullet card room.
Fig. 2 is three-dimensional structure diagram of the present invention.
In figure: 1, bullet card room; 11, internal thread; 12, through hole; 13, external screw thread; 14, bulge loop; 2, seat ring.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 2, the bullet card cell structure for drilling tool clamping of the present embodiment, comprise bullet card room 1, bullet card room 1 is tubular structure and with central through hole 12, one end of bullet card room 1 is with internal thread 11, and the other end is with external screw thread 13, and the medial side cornice of the through hole 12 of bullet card room 1 has bulge loop 14, the internal diameter of bulge loop 14 is less than the diameter of through hole 12, clamping drilling tool in bulge loop 14.
The present invention substitutes traditional seat ring by bulge loop, because bulge loop and bullet card room are structure as a whole, compare the Split type structure of seat ring and bullet card room, avoid when drilling rod rotates in the inconsistent phenomenon of drilling tool, and improve the precision and stability that are connected with drilling tool, improve the reliability of drilling rod work.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention is see claim, and when without prejudice to spirit of the present invention, the present invention can do any type of amendment.
