Abstract

The utility model discloses an assembled plum blossom pipe, it includes central pipe (1) and outer pipe (2), central pipe (1) and outer pipe (2) is connected through inlaying card strip (4) and draw -in groove (5) together, card strip (4) and draw -in groove (5) is fixed in the surface of central pipe (1) or outer pipe (2) respectively, the cross section of its junction is the arc, the internal surface of center pipe (1) and outer pipe (2) still is equipped with arc arch (3). The utility model discloses a card strip and draw -in groove fit together central pipe and excircle pipe, can conveniently produce the plum blossom pipe of corresponding hole count according to the in -service use needs, can adapt to the place of multiple demand, the arc arch of the internal surface of center pipe and outer pipe can be avoided artificially alternating cable or cable self rotation and led to the fact wearing and tearing to body itself to extension plum blossom pipe life has overcome not enough among the prior art.

Description

A kind of assembly type plum tube

Technical field

The utility model relates to a kind of assembly type plum tube.

Background technology

Along with the develop rapidly of electron trade, plum tube is widely used. Plum tube on market is porous integrated formed structure, and the plum tube of single specification can only be suitable for single place, can not meet the user of multiple demand; The inner surface of plum tube is generally smooth in addition, in use, because artificial cable or the cable self of interting rotates and cause wearing and tearing, can shorten the service life of plum tube.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of assembly type plum tube is provided, and can adapt to the place of multiple demand, extends plum tube service life, to overcome deficiency of the prior art.

The technical solution of the utility model: it comprises center pipe and outer pipe, center pipe is connected with draw-in groove by the card article that can be embedded in together with outer pipe; Card article and draw-in groove are individually fixed in the outer surface of center pipe or outer pipe, the cross section of its junction is arc; The inner surface of center pipe and outer pipe is also provided with arc convex.

Compared with prior art, the utility model fits together center pipe and outer pipe by card article and draw-in groove, can produce easily according to actual needs the plum tube of corresponding hole count, can adapt to the place of multiple demand; The arc convex of center pipe and cylindrical pipe internal surface can be avoided artificially interting cable or cable self and rotate body itself is caused to wearing and tearing, thereby extends plum tube service life.

Brief description of the drawings

Accompanying drawing 1 is structural representation of the present utility model;

Accompanying drawing 2 is the partial enlarged drawing of accompanying drawing 1.

Detailed description of the invention

Embodiment of the present utility model: first producing inner surface has center pipe 1 and the outer pipe 2 of arc convex 3; Next produces card article 4 and the draw-in groove 5 that can be embedded in together, and card article 4 and draw-in groove 5 are made as to arc (to increase the contact-making surface of card article 4 and draw-in groove 5 and body) with the cross section of body junction; Then select the outer pipe 2 of respective numbers according to user demand, by card article 4 and draw-in groove 5 be adhesively fixed respectively in center pipe 1 or outside the outer surface of pipe 2, together with finally card article 4 being embedded in mutually with draw-in groove 5.

Card article 4 and draw-in groove 5 can be produced plurality of specifications, to adapt to center pipe 1 and the outer pipe 2 of plurality of specifications.

Claims

1. an assembly type plum tube, it comprises center pipe (1) and outer pipe (2), it is characterized in that: center pipe (1) is connected with draw-in groove (5) by the card article (4) that can be embedded in together with outer pipe (2); Card article (4) and draw-in groove (5) are individually fixed in the outer surface of center pipe (1) or outer pipe (2), the cross section of its junction is arc; The inner surface of center pipe (1) and outer pipe (2) is also provided with arc convex (3).
