Detailed Description

The invention will be further explained with reference to the drawings and the specific embodiments.

Example 1

Please refer to fig. 1-3, the utility model provides a pipe connecting piece, including at least two concatenation units 1 that can dismantle the connection, at least two concatenation units 1 splice each other and form confined hollow tubular structure, and the both ends of every concatenation unit 1 are equipped with accommodation space 1a respectively, and accommodation space 1a mutually perpendicular at concatenation unit 1 both ends sets up. All be equipped with syntropy extension's locating part 2 in accommodation space 1a, be equipped with logical groove 3 on the locating part 2 in one of them accommodation space 1 a. The through groove 3 is convenient to match with the ejector pin during demoulding, so that quick demoulding is realized.

Specifically, the accommodating space 1a is an arc-shaped accommodating groove. The limiting members 2 are spaced apart from each other on the inner side wall of the accommodating space 1a, so that the pipe connecting member is not easily disengaged from the pipe fitting 5. The limiting part 2 is a convex block or a groove and is arc-shaped. The pipe fitting 5 is accommodated in the hollow tubular structure, the outer wall of the pipe fitting 5 which is matched with the pipe connecting piece is provided with a limit groove 5a or a limit block which is matched with the convex block or the groove, the pipe fitting 5 can be solid or hollow, and the inner side wall of the hollow pipe fitting is provided with a limit groove. The thickness of the limiting part 2 can be adjusted according to whether a limiting groove or a limiting block is arranged on the pipe fitting, for example, when the limiting groove or the limiting block is not arranged on the pipe fitting, the thickness of the limiting part 2 can be properly reduced.

Preferably, the splicing device further comprises a connecting piece 4, and at least two splicing units 1 are connected through the connecting piece 4.

For the installation of the pipe fittings 5 with different sizes, the convex blocks of the two splicing units 1 can be respectively embedded into the grooves on the two sides of the pipe fitting 5, and then the two splicing units 1 are fixed together through the connecting piece 4. For larger diameter pipes 5, the length of the connecting element 4 can be increased to suit the actual installation requirements.

Specifically, the connecting member 4 is a screw 41 and a nut 42, the outer side of each splicing unit 1 is provided with an accommodating groove 1c, the accommodating groove 1c is provided with a through hole 1d penetrating through the splicing unit 1, the screw 41 penetrates through the through hole 1d to be connected with the nut 42, the nut 42 is accommodated in one accommodating groove 1c in a matching manner, and the head of the screw 41 is accommodated in the other accommodating groove 1 c.
