Abstract
The utility model discloses a metal pipe connecting structure which comprises a pipe body, a pipe joint, a sealing ring and a pipe joint sleeve, wherein the end part of the pipe body swells to from a protruding ring, the pipe joint sleeve is clamped and sleeved at the rear side of the protruding ring, and the sealing ring is arranged on a pipeline close to the orifice section of the pipe body. The metal pipe connecting structure is characterized in that a plurality of protruding blocks with inclined planes are distributed at the end part of the pipe joint along the circumference direction, and rotary latches capable of respectively sliding along the inclined planes of the protruding blocks and being clamped and fixed on the inclined planes of the protruding blocks are arranged in the pipe joint sleeve; the pipe joint sleeve is in rotating connection with the pipe joint, and a limit block matched with the pipe joint sleeve is arranged on the periphery of the protruding blocks with the inclined planes on the pipe joint. The end part of the metal pipe connecting structure does not need damaged processing, so that the metal material consumption of the pipe body is greatly reduced and the production cost is greatly reduced, and the pipe end connecting positions have strong anti-pressure and anti-tension strength, simple and firm connection, good tightness and loosening resistance.
Description
Technical field
The utility model relates to the technical field of liquid, air shooter connection, more particularly relates to the pipe fitting that is tightly connected.
Background technique
Traditional thin metallic tubd Placement is based on clamp-press type, welding type and thread type.Its deficiency of clamp-press type and welding type is that its installation requirement is relative higher, and is difficult to dismounting after installing; Be in the damage that then is prone to when connecting processing pipe welding seam for pipe welding seam, thereby influence sealability.Thread type connects the ways that adopt damage tubing end more in the prior art, promptly opens the hinge worm tooth at pipe end, so that be connected with the screw-internal thread fit of pipe joint, can the scarifying phenomenon might occur with vibrations after the pipe fitting of thread type is installed.
Summary of the invention
The purpose of this utility model is exactly that provide for the deficiency that solves prior art a kind of not only is connected firmly good seal performance, and anti-loose metal pipe connection structure.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of metal pipe connection structure, comprise body, pipe joint, seal ring and pipe joint cover, the end protuberance of body forms bulge loop, pipe joint cover cutting ferrule is in the bulge loop rear side, seal ring is positioned near on the pipeline of body mouth section, it is characterized in that: the end of described pipe joint is distributed with the projection that several have the inclined-plane along its circumferencial direction, is provided with the spinner that can slide and connect and fix with it along the projection inclined-plane in the pipe joint cover.
As further specifying of such scheme, described spinner is several fixture blocks that the edge that matches with the pipe joint projection of moulding circumferentially distributes in the pipe joint cover, and the quantity of this fixture block is consistent with projection.
Be provided with back-up ring between described seal ring and the bulge loop, it is inner that seal ring, bulge loop and back-up ring all are packaged in the pipe joint cover.
The inwall of described pipe joint has and the corresponding shoulder hole of seal ring on the body, and bulge loop one side of body end and shoulder hole, back-up ring and the seal ring of pipe joint are closely withheld, and the opposite side of bulge loop and pipe joint cover are closely withheld.
Described pipe joint cover is rotationally connected with pipe joint, and the outer periphery that has the projection on inclined-plane on the pipe joint is equipped with the limiting stopper that matches with the pipe joint cover.
The angle of inclination on the inclined-plane of described projection along the pipe joint circle distribution is 15～60 °.
The sidepiece of described pipe joint and pipe joint cover forms boss, and boss is provided with through hole, is provided with fastening piece in the through hole pipe joint and pipe joint cover are connected to one.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts the projection of pipe joint end along several band inclined-planes that circumferentially distribute, spinner in the fit tube joints sleeve, make the bulge loop of body end protuberance, fitted seal circle and back-up ring again, it is inner all to be sealingly fastened in pipe joint and pipe joint cover, thereby realize being connected and fixed the purpose of two independent bodys, compare with the way of existing damage tubing end, the wall thickness of body can directly be set as required, need not to reserve the cutting surplus, the metal consumptive material of body is greatly reduced, cost of production reduces greatly, and pipe end link position compression and tensile strength height, connects simple, firmly, good airproof performance, anti-loose.

Embodiment
As Fig. 1～shown in Figure 4, a kind of metal pipe connection structure of the utility model, comprise body 1, pipe joint 2, seal ring 3 and pipe joint cover 4, the end protuberance of body 1 forms bulge loop 5, pipe joint overlaps 4 cutting ferrules in bulge loop 5 rear sides, seal ring 3 is positioned near on the pipeline of 1 mouthful of section of body, is provided with back-up ring 6 between seal ring 3 and the bulge loop 5, and seal ring 3, bulge loop 5 and back-up ring 6 all are packaged in pipe joint and overlap 4 inside.The inwall of pipe joint 2 has and the corresponding shoulder hole of seal ring 3 on the body 1, and bulge loop 5 one sides of body 1 end and shoulder hole, back-up ring 6 and the seal ring 3 of pipe joint 2 are closely withheld, and the opposite side of bulge loop 5 and pipe joint cover 4 are closely withheld.The end of pipe joint 2 is distributed with several projections that has inclined-plane 78 along its circumferencial direction, and the angle of inclination on inclined-plane 7 is 15～60 °, generally gets 30 ° for optimum.Be provided with the spinner 9 that can slide and connect and fix in pipe joint 2 covers along the projection inclined-plane with it.In the present embodiment, several fixture blocks that spinner 9 circumferentially distributes for the edge that matches with pipe joint projection 8 of moulding in the pipe joint cover 4, the quantity of this fixture block is consistent with projection 8.Pipe joint cover 4 is rotationally connected with pipe joint 2, and the outer periphery that has the projection 8 on inclined-plane on the pipe joint 2 is equipped with and pipe joint cover 4 limiting stoppers that match.Make pipe joint cover 4 along in the process of pipe joint 2 rotations, limiting stopper is circumferentially located it, prevents that pipe joint from overlapping 4 transition rotation, makes its inner spinner 9 break away from the projection that has the inclined-plane.Pipe joint 2 forms boss 10 with the sidepiece of pipe joint cover 4, boss 10 is provided with through hole 11, is provided with fastening piece in the through hole 11 pipe joint and pipe joint cover are connected to one, and relatively rotates to avoid pipe joint and pipe joint cover, wherein, fastening piece is screw, bolt or pin.
