Abstract
The utility model discloses a kind of metal pipe connection structure, comprise multiple end to end body, be mutually socketed between adjacent tubes, wherein the outer tube diameter of the upper tube body of socket place and the interior caliber of lower tube body suitable.Upper lower tube body is directly connected by the mode of pipe in outer tube sleeve, very simple and efficient, by necking down process, the caliber of body reduced or adopt mouthful technique that rises to be expanded by the caliber of body, manufacture very convenient during manufacture body.
Description
Technical field
The utility model relates to a kind of linkage structure of metallic conduit.
Background technique
Metal tube is the building storm-water drainage facility or electric wire penetration pipe commonly used the most, and its structure is generally need many body head and the tail to be formed by connecting, and the installation between existing body generally adopts the mode such as welding or card pressure to fix, and bothers very much.
Summary of the invention
The purpose of this utility model is to provide a kind of metal pipe connection structure, directly upper lower tube body socket can be realized connecting, easy for installation.
The utility model realizes above-mentioned purpose like this:
Metal pipe connection structure, comprises multiple end to end body, is mutually socketed between adjacent tubes, wherein the outer tube diameter of the upper tube body of socket place and the interior caliber of lower tube body suitable.
Wherein, the socket place of described upper lower tube body matches fixing by protruding and the recess corresponding to projection.
Wherein, the upper tube body outer wall of described socket place is provided with screw thread, and the inwall of corresponding lower tube body is also provided with screw thread, and upper lower tube body spins fixing by screw thread.
Wherein, the upper tube body of described socket place or lower tube body connecting end portion are pressed with several grooves.
Wherein, described groove is axially arranged, and the end surrounding along body is evenly arranged.
Wherein, the sectional shape of described body can be circular or polygonal.
The beneficial effects of the utility model are: upper lower tube body is directly connected by the mode of pipe in outer tube sleeve, very simple and efficient, by necking down process, the caliber of body reduced during manufacture body or adopt mouthful technique that rises to be expanded by the caliber of body, manufacturing very convenient.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is the structural representation of the first embodiment of the utility model;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1;
Fig. 3 is the structural representation of the utility model the second embodiment;
Fig. 4 is the part-structure schematic diagram of the third embodiment of the utility model.
Embodiment
Referring to figs. 1 through Fig. 3, metal pipe connection structure, comprises multiple end to end body, is mutually socketed between adjacent tubes, wherein the outer tube diameter of the upper tube body 11 of socket place and the interior caliber of lower tube body 12 suitable.Upper lower tube body 11,12 is directly connected by the mode of pipe in outer tube sleeve, very simple and efficient, by necking down process, the caliber of body reduced or adopt mouthful technique that rises to be expanded by the caliber of body, manufacture very convenient during manufacture body.Wherein, this metal tube is rain pipe or penetration pipe, with the making of Stainless Steel Tube, Al-alloy pipe or galvanized pipe, does not need to be tightly connected between tube and tube.
For making the connection between upper lower tube body 11,12 more reliable, the socket place of described upper lower tube body 11,12 matches fixing by protruding 13 and the recess 14 corresponding to projection 13, after with strength upper tube body 11 being inserted in lower tube body 12 during installation, just be difficult to throw off both projection 13 and recess 14 coordinate, connect very firm.Can also be that upper tube body 11 outer wall of described socket place is provided with screw thread in addition, the inwall of corresponding lower tube body 12 be also provided with screw thread, and upper lower tube body 11,12 spins fixing by screw thread.
In addition, as shown in Figure 4, upper tube body 11 or lower tube body 12 connecting end portion of described socket place are pressed with several grooves 2, just can realize connecting when being inserted in another body the body end being provided with groove 2, easy to operate.Wherein, described groove 2 is axially arranged, and the end surrounding along body is evenly arranged, and further facilitates the grafting of body with this.Certainly, the two ends of upper tube body 11 or lower tube body 12 can arrange groove 2 and realize connection.
According to the needs that reality uses, the sectional shape of described body can be circular or polygonal.
