Abstract
The invention relates to a connecting pipe structure for a drilling tool. The connecting pipe structure comprises a connecting sleeve. The connecting sleeve is of a hollow cylinder structure. A plurality of steps are arranged in the connecting sleeve, a first internal thread and a second internal thread are arranged on the upper portion of the connecting sleeve and the bottom of the connecting sleeve respectively, a steel ball rack is installed at the position of the step below the first internal thread, and a steel ball is installed on the steel ball rack. The connecting pipe structure for the drilling tool is compact and reasonable in structure and convenient to manufacture and install. Due to the fact that the steel ball rack is installed in the connecting sleeve and the steel ball is installed on the steel ball rack, the sealing performance of the steel ball in the connecting sleeve is effectively guaranteed. Furthermore, the steel ball rack is made of plastics and is soft, when pressure is generated in the connecting sleeve, the steel ball has certain buffer action on the steel ball rack, the sealing performance of the steel ball can be guaranteed still, and therefore the connecting pipe structure is reliable to use and high in working efficiency.
Description
Technical field
The present invention relates to boring tool technical field, especially drilling tool connecting pipe structure.
Background technology
Probing is an important technical in geological prospecting work.When being drilling operation, boring tool is used in whole general name (not comprising guard aperture sleeve pipe) of drilling tubing post and joint thereof in boring.Drilling tool is comprised of reamer and the drill bit of kelly, drilling rod, basket and bottom.
In prior art, drilling tool connecting pipe structure, comprises adapter sleeve, described adapter sleeve adopts common hollow cylinder body structure, be positioned at tube connector and be provided with steel ball, it is simple in structure, easy for installation, but only rely on the combination of steel ball and adapter sleeve, its poor sealing, in drilling tool use procedure, can produce pressure in adapter sleeve, the phenomenon of easily leaking, affects the result of use of drilling tool.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of drilling tool connecting pipe structure rational in infrastructure, thereby guarantees the sealing performance of steel ball, and result of use is good, increases work efficiency.
The technical solution adopted in the present invention is as follows:
A kind of drilling tool connecting pipe structure, comprise adapter sleeve, described adapter sleeve becomes hollow cylinder body structure, in described adapter sleeve, be provided with a plurality of steps, the top and the bottom that are positioned at adapter sleeve are respectively arranged with the first internal thread and the second internal thread, the step place that is positioned at the first internal thread bottom is provided with steel ball rack, in described steel ball rack, steel ball is installed.
Further improvement as technique scheme:
Described steel ball rack adopts plastic material.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, reasonable, make with easy for installation, by steel ball rack is installed in adapter sleeve, steel ball is installed in steel ball rack again, effectively guarantee the sealing performance of steel ball in adapter sleeve, and steel ball rack adopts plastics material for making clothes, softer, while producing pressure in adapter sleeve, steel ball has certain cushioning effect in steel ball rack, still can guarantee its sealing performance, it uses reliable, and operating efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, adapter sleeve; 2, the first internal thread; 3, steel ball rack; 4, steel ball; 5, the second internal thread.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the drilling tool connecting pipe structure of the present embodiment, comprise adapter sleeve 1,1 one-tenth hollow cylinder body structure of adapter sleeve, in adapter sleeve 1, be provided with a plurality of steps, the top and the bottom that are positioned at adapter sleeve 1 are respectively arranged with the first internal thread 2 and the second internal thread 5, and the step place that is positioned at the first internal thread 2 bottoms is provided with steel ball rack 3, and steel ball 4 is installed in steel ball rack 3.
Steel ball rack 3 adopts plastic material.
In actual use procedure, the bullet card holder that drilling tool is installed at the first internal thread 2 places of adapter sleeve 1, the axle of drilling tool is installed at the second internal thread 5 places.
During work, when the interior generation pressure of adapter sleeve 1 of drilling tool, because the steel ball rack 3 of plastic material can produce plastic strain, steel ball 4 still can, in its sealing performance of the interior assurance of adapter sleeve 1, use reliable, safety.
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.
