Abstract
The utility model discloses a seal structure of threaded pipe spare, include: the sealing ring comprises a hollow tubular body, wherein an annular boss protruding inwards is arranged on the inner circumference of the tubular body, internal threads are arranged on the side circumference of the tubular body along one side of the annular boss, and an annular sealing ring is placed on the annular boss. Because the sealing ring is arranged in the tubular body, when the sealing structure of the threaded pipe fitting is connected with other threaded outer pipes, and the threaded outer pipes and the threaded pipe fitting are screwed up in a rotating mode, the sealing ring is pressed, so that when liquid (such as water or other oil) or gas flows through the connecting part of the sealing structure and other threaded outer pipes, the waterproof adhesive tape or the raw adhesive tape does not need to be wound, and liquid or gas leakage can be prevented.
Description
Technical Field
The utility model belongs to the pipe connection spare field, concretely relates to seal structure of threaded pipe spare.
Background
In the process of connecting various tap water pipelines or oil pipelines or gas pipelines, in order to prevent tap water or various oil or gas from leaking when the pipelines are connected with the pipelines, when a tap or other components are connected, waterproof adhesive tapes or raw adhesive tapes are required to be wound on the joints of the pipelines, and the installation mode is troublesome. Patent CN201731194U discloses a sealing structure for threaded pipe fittings, which does not need waterproof adhesive tape or raw adhesive tape, but the sealing manner of the structure is complicated, and is not beneficial to the mass production of products.
SUMMERY OF THE UTILITY MODEL
The utility model provides a threaded pipe fitting's seal structure, its aim at provide one kind be different from prior art, need not twine waterproof adhesive tape or raw sticky tape can prevent the seal structure of threaded pipe fitting of water or oil seepage again.
The technical scheme of the utility model is like this:
a seal structure for a threaded fitting, comprising: the sealing ring comprises a hollow tubular body, wherein an annular boss protruding inwards is arranged on the inner circumference of the tubular body, internal threads are arranged on the side circumference of the tubular body along one side of the annular boss, and an annular sealing ring is placed on the annular boss.
Further, the internal thread and the tubular body are integrated or the internal thread is embedded on the inner circumference of the tubular body.
Further, the tubular body is made of metal or plastic.
Further, the internal thread is metal or plastic.
Further, the annular sealing ring is a rubber ring.
The technical effects of the utility model: because the sealing ring is arranged in the tubular body, when the sealing structure of the threaded pipe fitting is connected with other threaded outer pipes, and the threaded outer pipes and the threaded pipe fitting are screwed up in a rotating mode, the sealing ring is pressed, so that when liquid (such as water or other oil) or gas flows through the connecting part of the sealing structure and other threaded outer pipes, the waterproof adhesive tape or the raw adhesive tape does not need to be wound, and liquid or gas leakage can be prevented.

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, what fig. 1 shows is the structure diagram of the utility model, including hollow tubular body 4, on the inboard circumference of hollow tubular body 4, be provided with inside convex cyclic annular boss 3, one side on cyclic annular boss 3 has placed ring type seal 2, on the inboard circumference of tubular body 4 of 2 homonymies of ring type seal, is provided with internal thread 1. Of course, the internal thread 1 may be separately machined and then embedded into the tubular body 4, or may be integrally machined and formed with the tubular body 4. The tubular body 4 may be a metal piece or a plastic piece. Similarly, when the internal thread 1 and the tubular body 4 are integrated, the material of the internal thread 1 is the same as that of the tubular body 4, that is, the internal thread 1 and the tubular body 4 may be made of metal pieces, plastic pieces or a mixture of metal pieces and plastic pieces; when the internal thread 1 is embedded into the tubular body 4, the material of the internal thread 1 may be different from the material of the tubular body 4, that is, when the material of the tubular body 4 is a metal member or a plastic member, the material of the internal thread 1 may be a plastic member or a metal member. When the tap or the threaded outer pipe is screwed into the tubular body 4, the annular sealing ring 2 is pressed, so that liquid (such as water or other oil) or gas can be prevented from leaking through the connecting part of the sealing structure and other threaded outer pipes without winding waterproof adhesive tapes or raw adhesive tapes.
Preferably, the annular sealing ring 2 is a rubber ring, and the cross section of the rubber ring can be circular or rectangular.
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.
