Description
Technical Field
The utility model relates to a drilling tool, concretely relates to drilling rod.
Background
The drilling rod is often used for well drilling or bore the deep hole in the building work progress, and the length of current drilling rod can not be adjusted, when needs bore out the hole of the different degree of depth, requires the job site to be equipped with the drilling rod of a plurality of different length, and the volume of single drilling rod is big, and is with high costs, is equipped with a plurality of drilling rods simultaneously, has not only improved the overall cost of project, and the removal process such as transportation also has a great deal of inconvenience moreover, therefore it can conveniently adjust the drilling rod of length to be necessary to design one kind.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a drilling rod to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a drill rod, including the upper rod body, the lower rod body and adjusting sleeve, the three all is the columnar body that the diameter is the same, the drill bit is established to the lower extreme of the lower rod body, the central point department of upper end terminal surface establishes along the inside sunken screw thread deep hole of axial, the central point department of upper rod body lower extreme terminal surface connects the double-screw bolt of its axial extension downwards, the diameter of double-screw bolt is the same with the aperture of screw thread deep hole, and the external screw thread on the double-screw bolt matches with the internal thread of screw thread deep hole, the center pin department of adjusting sleeve establishes the through hole that runs through from top to bottom, the aperture of through hole is also the same with the diameter of double-screw bolt, respectively.
Preferably, for the drill rod, the length of the stud is less than or equal to the depth of the threaded deep hole.
Preferably, for the drill rod, a plurality of adjusting sleeves are arranged, and the heights of the adjusting sleeves are different.
Compared with the prior art, the beneficial effects of the utility model are that:
The utility model provides a drill rod, the structure of the body of rod is unchangeable under the body of rod of going up, but every drill rod is equipped with the different adjustment cover of a plurality of specifications, the double-screw bolt of going up body of rod bottom passes earlier and twists the screw thread deep hole on the body of rod down after the through hole on the adjustment cover again, constitute complete drilling rod, when the length of needs adjustment drill rod, screw out in the screw thread deep hole with the double-screw bolt, take off and change the adjustment ways of high difference back on the double-screw bolt and twist the screw thread deep hole again with the double-screw bolt in, because the height of adjustment cover has been high or has been short, the degree of depth that the screw bolt was twisted into the screw thread deep hole then will be corresponding shallowly or deepening, thereby make the overall length of drilling rod outward appearance become or shorten after screwing up, this drilling rod is when using, creep into. The drilling rod is equipped on a construction project, only a plurality of required adjusting sleeves are needed to be equipped, and a plurality of complete drilling rods with different lengths are not needed to be equipped, so that the cost is greatly reduced, the volume and the weight of the adjusting sleeves are greatly reduced compared with those of the complete drilling rods, and convenience is brought to movement and transportation.

Fig. 1 is a schematic structural view of the present invention;
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: the utility model provides a drill rod, including the upper rod body 1, the lower rod body 2 and adjusting sleeve 3, the three all is the columnar body that the diameter is the same, drill bit 4 is established to the lower extreme of the lower rod body 2, the center department of upper end terminal surface establishes along the inside sunken screw thread deep hole 5 of axial, the center department of the lower extreme terminal surface of the upper rod body 1 connects the double-screw bolt 6 of its axial extension downwards, the diameter of double-screw bolt 6 is the same with the aperture of screw thread deep hole 5, and the external screw thread on the double-screw bolt 6 matches with the internal thread of screw thread deep hole 5, the center pin department of adjusting sleeve 3 establishes through-hole 7 that runs through from top to bottom, the aperture of through-hole 7 is also the same with the diameter of double-screw bolt 6, respectively establish.
in another embodiment, the length of the stud 6 is less than or equal to the depth of the threaded recess 5.
In another embodiment, the adjusting sleeve 3 is provided in plurality, and the height of each adjusting sleeve 3 is different.
The structure of the upper rod body 1 and the lower rod body 2 of the drill rod provided by the utility model is unchanged, but each drill rod is provided with a plurality of adjusting sleeves 3 with different specifications, the stud 6 at the bottom of the upper rod body 1 firstly passes through the through hole 7 on the adjusting sleeve 3 and then is screwed into the threaded deep hole 5 on the lower rod body 2 to form a complete drill rod, when the length of the drill rod needs to be adjusted, the stud 6 is screwed out of the threaded deep hole 5, the adjusting sleeve 3 with different heights is taken down and replaced to be sleeved on the stud 6, the stud 6 is screwed into the threaded deep hole 5 again, because the height of the adjusting sleeve 3 is high or low, the depth of the threaded stud 6 screwed into the threaded deep hole 5 becomes shallow or deep, so that the overall length of the appearance of the drill rod after screwing becomes shorter, when the drill rod is used, drilling is carried out along the screwing direction of the stud 6 in the threaded deep hole 5, and the stud 6 is prevented from being unscrewed in the threaded deep hole 5. The drilling rod is equipped on a construction project, only a plurality of required adjusting sleeves are needed to be equipped, and a plurality of complete drilling rods with different lengths are not needed to be equipped, so that the cost is greatly reduced, the volume and the weight of the adjusting sleeves are greatly reduced compared with those of the complete drilling rods, and convenience is brought to movement and transportation.
although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
