Abstract
The invention discloses a connecting piece for stainless steel pipes. The connecting piece comprises a pipe-shaped connecting piece body; connecting heads are arranged at two ends of the body, and are annular; the diameters of the connecting heads are larger than the diameter of the body; the connecting heads are in threaded connection with fastening pieces; the fastening pieces consist of annular first parts and second parts; the diameters of the second parts are larger than the diameters of the first parts; and the diameters of the first parts are equal to the inner diameters of the connecting heads. The connecting piece is simple in structure and convenient for installation and disassembly operations, can finish synchronous fixation of two ends of the pipes without needing cooperation of two or more workers, uses the fastening pieces and the connecting heads for tightly connecting the two stainless steel pipes to reduce the looseness condition of the stainless steel pipes, and is excellent in tightness and few in leakage conditions.
Description
Technical field
The present invention relates to a kind of pipe connecting component, particularly relate to a kind of link for Stainless Steel Tube.
Background technique
At present on the market for being communicated with gas, the pipe joint of water or other liquid, have directly, elbow, threeway etc., the link interface of the form that is spirally connected is adopted to be provided with screw thread, when installing and using, pipeline and joint are by leather packing, or at material that expands such as screw thread place cover raw meal belts, be fastenedly connected by fastening screw, with leakage proof, but because leather packing is easily aging, working life is short, to often change, and overlap raw meal belt etc. and expand and expect that installation and maintenance bother, in addition, current like product on the market, because of the defect in structural design, after one end of pipeline is fixing, when the fixing the other end is installed again, rotation because of pipeline can make again just fixing one end also loosen, so at work progress, two or more workman is needed to coordinate the two ends of fixing tube simultaneously just can complete, which adds artificial input, increase installation cost, simultaneously to the technical requirements of workmen and installation precision higher.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of link for Stainless Steel Tube.
The present invention is achieved through the following technical solutions:
A kind of link for Stainless Steel Tube, comprise the link body of tubulose, described body two ends are provided with connecting head, described connecting head is annular, its diameter is greater than described body diameter, and described connecting head is threaded a fastening piece, and described fastening piece is made up of the first portion of annular and second portion, the diameter of second portion is greater than the diameter of first portion, and the diameter of first portion is identical with connecting head internal diameter.
Described a kind of link for Stainless Steel Tube, described first portion and second portion joint are provided with seal ring.
Described a kind of link for Stainless Steel Tube, one end that described first portion is not connected with second portion is truncated cone.
Described a kind of link for Stainless Steel Tube, in described body, middle part is provided with elastic bumps.
Described a kind of link for Stainless Steel Tube, described body interior is provided with neck bush, and described neck bush is made up of elastic material.
Described a kind of link for Stainless Steel Tube, be arranged with snap ring outside described neck bush, described body is provided with the draw-in groove corresponding with snap ring.
The beneficial effect that the present invention reaches:
Connecting-piece structure of the present invention is simple, mounts and dismounts easy to operate, coordinates the two ends of fixing tube simultaneously to complete without the need to two or more workman; By fastening piece and connecting head by two Stainless Steel Tube compact siro spinning technology, decrease the situation that Stainless Steel Tube occurs to loosen, meanwhile, good seal performance, the situation of leakage is few.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, body, 2, connecting head, 3, fastening piece, 31, first portion, 32, second portion, 4, seal ring, 5, elastic bumps, 6, neck bush, 7, snap ring, 8, draw-in groove, 10, Stainless Steel Tube.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technological scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in the figure, a kind of link for Stainless Steel Tube of the present invention, comprise the link body 1 of tubulose, described body 1 two ends are provided with connecting head 2, and described connecting head 2 is annular, and its diameter is greater than described body 1 diameter, described connecting head 2 is threaded a fastening piece 3, described fastening piece 3 is made up of the first portion 31 of annular and second portion 32, and the diameter of second 32 points is greater than the diameter of first portion 31, and the diameter of first portion 31 is identical with connecting head 2 internal diameter.
Particularly, described first portion 31 is provided with seal ring 4 with second portion 32 joint.Seal ring 4 improves the sealability of fastening piece 3.In order to improve the sealability of fastening piece further, one end that described first portion 31 is not connected with second portion 32 is set to truncated cone.
Particularly, in described body 1, middle part is provided with elastic bumps 5, and described elastic bumps 5 is multiple, be arranged on a circle in body 1 uniformly, be provided with the described elastic bumps 5 of two circles in body 1, elastic bumps 5 can closely engage Stainless Steel Tube 10, prevents Stainless Steel Tube 10 from occurring to loosen.
A more progressive ground, described body 1 inside is provided with neck bush 6, and described neck bush 6 is made up of elastic material.Fully engaging Stainless Steel Tube by arranging flexible liner cover 6, can not leak because stainless steel expands with heat and contract with cold simultaneously.Particularly, be arranged with snap ring 7 outside described neck bush 6, described body 1 is provided with the draw-in groove 8 corresponding with snap ring 7.Snap ring 7 is fastened in draw-in groove 8, thus is fixedly connected with body 1.
Link of the present invention in use, need two Stainless Steel Tubes 10 connected, through fastening piece 3, be positioned in body 1 from body 1 both sides, fastening piece 3 is screwed into the connecting head 3 on body 1, diameter due to second portion 32 is greater than the diameter of first portion 31, and first portion 31 and connecting head 2 screw thread compact siro spinning technology, improve sealability.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
