Abstract
The invention relates to a screw protection cap for a drill rod. The screw protection cap comprises a screw protection cap body, wherein the screw protection cap body is a conical table matched with the end part of the drill rod in shape; the screw protection cap body comprises two half structures comprising a first half cap and a second half cap; one side of the first half cap and one side of the second half cap are connected through a hinge; an openable and closable opening is formed in the other sides of the first half cap and the second half cap; a screw thread is arranged on corresponding circumferential surfaces of the first half cap and the second half cap; after being combined, the first half cap and the second half cap are locked through a locking ring mounted at the screw thread; the screw protection cap body sequentially comprises an opening enlargement straight tube ring, a conical ring and an opening contraction straight tube ring from an opening enlargement part to an opening contraction part; and the hinge between the first half cap and the second half cap is mounted at the opening enlargement straight tube ring and the opening contraction straight tube ring. The screw protection cap is mounted at the end part of the drill rod in a direct sleeving manner, spiral mounting is not required, the mounting speed is increased, the damage to a screw thread at the end part of the drill rod is further avoided, and the screw protection cap has the characteristics of simple structure and good protection effect.
Description
Technical field
The present invention 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 thread protecting cap
With female thread, need during installation to be connected with drill rod end spiral, the most time-consuming, and the screw thread of drilling rod be there is also certain journey
The damage of degree.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of drilling rod thread protecting cap, and this thread protecting cap is directly placed on drill rod end, contracting
The short set-up time, and avoid the damage to drill rod thread completely.
In order to solve the problems referred to above, the present invention uses following scheme:
A kind of drilling rod thread protecting cap, including thread protecting cap body, thread protecting cap body is the circular cone shape fitted mutually with drill rod end profile,
Described thread protecting cap body is made up of two halves structure, and including the first half caps and the second half caps, the side of the first half caps and the second half caps leads to
Crossing chain connection, 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 screw thread, and
After half cap 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, first
Hinge between half cap and the second half caps is installed at enlarging straight tube ring and reducing straight tube ring.
The method have technical effect that:
The thread protecting cap of the present invention, uses the mode being directly nested with to be installed on drill rod end, it is not necessary to spiral is installed, and not only improves installation
Speed, also avoids the damage to drill rod end screw thread, has simple in construction, a feature that protected effect is good.
Accompanying drawing explanation
Fig. 1 is the three-dimensional structure diagram of the present invention.
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 is straight
Cylinder ring；8, circular cone ring；9, reducing straight tube ring.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention 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 drilling rod
The circular cone shape that end profiles 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
The corresponding periphery of the second half caps 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 screw thread 5
The retaining ring 6 at place is locked.
Thread protecting cap body to choke, includes enlarging straight tube ring 7, circular cone ring 8 and reducing straight tube ring 9, for side from expansion mouth successively
Just 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 drill rod end,
After drill rod end is fully recessed between the first half caps 1 and the second half caps 2, both is closed up, after closing up, retaining ring 6 is installed on
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 repeatedly weigh
Multiple utilization.
Embodiment provided above is the better embodiment of the present invention, is only used for the convenient explanation present invention, not appoints the present invention
What pro forma restriction, has usually intellectual, if without departing from the carried technical characteristic of the present invention in any art
In the range of, utilize the Equivalent embodiments that the done local of disclosed technology contents is changed or modified, and without departing from this
Bright technical characteristic content, all still falls within the range of the technology of the present invention feature.
