Abstract
The invention discloses a threaded seamless steel tube. The threaded seamless steel tube comprises a first tube body and a second tube body. Internal threads are arranged at one end inside the first tube body, an inner check ring is arranged in the other end of the first tube body, a threaded connecting base is arranged outside the other end of the first tube body, external threads are arranged at one end of the second tube body, the external threads of the second tube body are matched with the internal threads of the first tube body, and the other end of the second tube body is matched with the inner check ring. Through the mode, the stability of the threaded seamless steel tube can be improved, and the threaded seamless steel tube is convenient to use, fast to disassemble and assemble, safe and reliable.
Description
Technical field
The present invention relates to seamless steel pipe field, particularly relate to a kind of thread type seamless steel pipe.
Background technique
Along with growth in the living standard, the machinery of processing and carrier mostly has high safety and reliability requirement for equipment and materials, original common stainless steel carft of construction, may not necessarily adapt to modern industry environment for safety and the reliability requirement of the industries such as logistics.Original steel pipe is easily corroded in use, and steel strength is more weak, has shortened the working life of steel pipe, and the replacing of steel pipe, installation and maintenance are cumbersome, also exists and is connected unsettled defect with installation connecting element.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of thread type seamless steel pipe, can improve the stability of seamless steel steel pipe, and easy to use, dismounting is quick, safe and reliable.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of thread type seamless steel pipe is provided, it is characterized in that, comprise the first body and the second body, one end of the inside of described the first body is provided with internal thread, and the inside of the other end of the first body is provided with inner step ring, the outer installment seat that is threaded, one end of described the second body is provided with outside thread, and the internal thread of the outside thread of described the second body and the first body matches, and the other end matches with inner step ring.
In a preferred embodiment of the present invention, described the second body is cylindrical, and the cross section of the inside of described the first body is cylindrical.
In a preferred embodiment of the present invention, on described internal thread and outside thread, be provided with wearing layer, the thickness of described wearing layer is 0.01-0.05mm.
In a preferred embodiment of the present invention, described inner step ring, be threaded seat and the first body be formed in one.
In a preferred embodiment of the present invention, the length of described the second body is less than the length of the first body.
The invention has the beneficial effects as follows: thread type seamless steel pipe of the present invention, can improve the stability of seamless steel steel pipe, easy to use, dismounting is quick, safe and reliable.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:
Fig. 1 is the structural representation of thread type seamless steel pipe one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, the first body, the 2, second body, 3.Inner step ring, 4, the seat that is threaded.
Embodiment
Below the technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, a kind of thread type seamless steel pipe, it is characterized in that, comprise the first body 1 and the second body 2, one end of the inside of described the first body 1 is provided with internal thread, and the inside of the other end of the first body 1 is provided with inner step ring 3, outer installment be threaded seat 4, one end of described the second body 2 is provided with outside thread, and the internal thread of the outside thread of described the second body 2 and the first body 1 matches, and the other end matches with inner step ring 3.
In addition, described the second body 2 is cylindrical, and the cross section of the inside of described the first body 1 is cylindrical.
In addition, on described internal thread and outside thread, be provided with wearing layer, the thickness of described wearing layer is 0.01-0.05mm.
In addition, described inner step ring 3, seat the 4 and first body 1 that is threaded are formed in one.
In addition, the length of described the second body 2 is less than the length of the first body 1.
Be different from prior art, thread type seamless steel pipe of the present invention, can improve the stability of seamless steel steel pipe, and easy to use, dismounting is quick, safe and reliable.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
