Description
Technical field
This utility model relates to drilling rod used for geological prospecting, particularly to the safety device of drilling rod.
Background technology
Drilling rod is in storage and transport process, for preventing its end to be collided damage, it is generally required to install thread protecting cap.Existing protect
Silk hatband has female thread, needs to be connected with drill rod end spiral during installation, the most time-consuming, and the screw thread of drilling rod be there is also one
Determine the damage of degree.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of drilling rod thread protecting cap, and this thread protecting cap is directly placed on brill
Boom end, shortens the set-up time, and avoids the damage to drill rod thread completely.
In order to solve the problems referred to above, this utility model following scheme of employing:
A kind of drilling rod thread protecting cap, including thread protecting cap body, thread protecting cap body is the circular cone fitted mutually with drill rod end profile
Mesa-shaped, described thread protecting cap body is made up of two halves structure, including the first half caps and the second half caps, the first half caps and the second half caps
Side is connected through the hinge, and opposite side is provided with can the opening of folding；The corresponding periphery of the first half caps and the second half caps is provided with
After screw thread, the first half caps and the second half caps close up, lock by being installed on the retaining ring at described screw thread.
Further improvement as technique scheme:
Described thread protecting cap body to choke, includes enlarging straight tube ring, circular cone ring and reducing straight tube ring from expansion mouth successively,
Hinge between the first half caps and the second half caps is installed at enlarging straight tube ring and reducing straight tube ring.
Of the present utility model have the technical effect that
Thread protecting cap of the present utility model, uses the mode being directly nested with to be installed on drill rod end, it is not necessary to spiral is installed, not only
Improve installation rate, also avoid the damage to drill rod end screw thread, there is simple in construction, feature that protected effect is good.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present utility model.
Fig. 2 is the other direction view of Fig. 1.
In figure: 1, the first half caps；2, the second half caps；3, hinge；4, opening；5, screw thread；6, retaining ring；7, enlarging straight tube
Ring；8, circular cone ring；9, reducing straight tube ring.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further.
As shown in Figure 1 and Figure 2, the drilling rod thread protecting cap of the present embodiment, including thread protecting cap body, thread protecting cap body is and brill
The circular cone shape that boom end profile is fitted mutually, thread protecting cap body is made up of two halves structure, including the first half caps 1 and the second half caps 2,
Half cap 1 is connected by hinge 3 with the side of the second half caps 2, and opposite side is provided with can the opening 4 of folding；The first half caps 1 and second
The corresponding periphery of half cap 2 is provided with screw thread 5, the first half caps 1 and the second half caps 2-in-1 hold together after, by being installed on the lock at screw thread 5
Tight ring 6 is locked.
Thread protecting cap body to choke, includes enlarging straight tube ring 7, circular cone ring 8 and reducing straight tube ring 9 from expansion mouth successively,
For convenience of the installation of hinge 3, hinge 3 is installed at enlarging straight tube ring 7 and reducing straight tube ring 9.
During use, opening 4 is opened by hinge 3 by the first half caps 1 and the second half caps 2, after opening, is placed on drilling rod end
Both, after drill rod end is fully recessed between the first half caps 1 and the second half caps 2, is closed up, retaining ring 6 are installed after closing up by portion
At screw thread 5, the first half caps 1 are locked with the second half caps 2, thus thread protecting cap is stably installed on drill rod end；Whole installation
Simple to operate, quick, only retaining ring 6 need to be screwed off during dismounting, owing to installing without spiral, therefore can be repeated several times
Utilize.
Embodiment provided above is better embodiment of the present utility model, is only used for convenient explanation this utility model, and
Non-this utility model is made any pro forma restriction, any art has usually intellectual, if without departing from
In the range of the carried technical characteristic of this utility model, the done local of this utility model disclosed technology content is utilized to change or repair
The Equivalent embodiments of decorations, and without departing from technical characteristic content of the present utility model, all still fall within this utility model technical characteristic
In the range of.
