Abstract

The utility model discloses a cold contract self locking type plastic support plain strip, which comprises a main body of a plastic support plain strip, wherein both sides of main body of the plastic support plain strip are respectively provided with a left tongue-and-groove (2) and a right tongue-and-groove (4) composed of male fastening tenons and female fastening grooves corresponding to the male fastening tenons. The utility model provides a cold contract self locking type plastic support plain strip which is used for connecting cables and has the advantages that welding is not needed when the plastic support plain strip surrounds a pipe; the speed for surrounding the pipe is fast, and no electricity is consumed; the plastic structure plain strip can not be stretched to be broken; the structure is simple; the manufacture is convenient.

Description

Cold contract self locking type plastic support riglet

Technical field

The utility model relates to a kind of cold-contraction type electric cable accessories, particularly relates to a kind of cold contract self locking type plastic support riglet.

Background technology

Cable need coat silastic product in the joint in connection procedure, in order to cable joint is insulated, anticorrosion and antirust.The technology that adopts is earlier with the silastic product predilation at present, make the plastic support pipe with the plastic support riglet then, the plastic support pipe is placed in the silastic product of expansion, the silastic product of expansion is enclosed within on the cable, after cable connects, because the plastic support pipe so just can be pulled out the plastic support riglet quickly and easily by the establishment of plastic support riglet.This cold-contraction type electric cable accessories is the new technology product that has just risen in China in recent years, and it does not need special tool(s) with easy for installation, quick, does not especially use naked light and is extensively approved and use.But that adopts at present makes the plastic support pipe with the plastic support riglet, is to be provided with intermeshing tongue-and-groove in plastic support riglet both sides, with making the plastic support pipe after the tongue-and-groove engagement of plastic support riglet by both sides, will weld between the plastic support riglet again.The shortcoming that the plastic support riglet of this spline structure exists in the cable connection procedure is: need welding between the plastic support riglet, cause technology slow and power consumption around pipe speed, on the plastic support pipe pad is arranged, not attractive in appearance, because pad is sacrifices consisting of an ox, a sheep and a pig and might break the plastic support riglet between the plastic support riglet, the phenomenon that will cause cable to connect reconnecting takes place.

The utility model content

Technical problem to be solved in the utility model provides a kind of plastic support riglet the time does not need welding around pipe, around pipe soon and not power consumption around pipe speed, and the cold contract self locking type plastic support riglet that the plastic support riglet can not be broken.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: comprise plastic support riglet body, be respectively equipped with left tenon slot and the right tenon slot be made up of male clip tenon and corresponding female clip tenon in described plastic support riglet body both sides.

Described male clip tenon is to be extended with the hypotenuse that becomes 76 ° of angles with described plastic support riglet body at described plastic support riglet body sidewall, be provided with the circular arc bar in described hypotenuse end, between described hypotenuse and described plastic support riglet body, be formed with the female clip tenon that can hold described hypotenuse, and the spacing of described circular arc bar and described plastic support riglet body is slightly less than the spacing of described hypotenuse and described plastic support riglet body.

Described male clip tenon is to be extended with the hook-shaped edges that is formed with prominent beak in its end at described plastic support riglet body sidewall, is formed with the hook-type female clip tenon that can hold described hook-shaped edges between described hook-shaped edges and described plastic support riglet body.

Adopt the cold contract self locking type plastic support riglet of technique scheme, when cold contract self locking type plastic support riglet is compiled into auto-buckled type plastic support pipe, only need the left tenon slot of auto-buckled type plastic support riglet two offsides and the male clip tenon and the female clip tenon make-up of right tenon slot just can be fastened as cold contract self locking type plastic support riglet cold contract self locking type plastic support pipe.Compare with prior art: 1, original riglet has pad, and not attractive in appearance, the utility model does not have pad, and is smooth attractive in appearance; 2, original riglet slow and power consumption around pipe speed, the utility model is around 3-5 times of pipe speed-raising and not power consumption; 3, original riglet has tensile phenomenon to exist because of solder joint is sacrifices consisting of an ox, a sheep and a pig, and the utility model does not then have this phenomenon.

In sum, the utility model to be a kind of plastic support riglet do not need when pipe welding, around pipe speed soon and not power consumption, the plastic support riglet can not be broken and simple in structure, easily manufactured cold contract self locking type plastic support riglet.

Description of drawings

Fig. 2 is the utility model user mode schematic diagram;

Fig. 3 is another structural representation of the utility model;

Fig. 4 is another structure user mode schematic diagram of the utility model.

Embodiment

Following structure the drawings and specific embodiments are described in further detail the utility model.

Referring to Fig. 1 and Fig. 2, be extended with hypotenuse 7 with 1 one-tenth 76 ° of angle of plastic support riglet body at plastic support riglet body 1 sidewall, be provided with circular arc bar 8 in hypotenuse 7 ends, between hypotenuse 7 and plastic support riglet body 1, be formed with the female clip tenon 9 that can hold hypotenuse 7, and the spacing of circular arc bar 8 and plastic support riglet body 1 is slightly less than the spacing of hypotenuse 7 and plastic support riglet body 1.

When cold contract self locking type plastic support riglet is compiled into auto-buckled type plastic support pipe, only need auto-buckled type plastic support riglet coiled circle shape, the female clip tenon that can hold hypotenuse 79 that the hypotenuse 7 and the circular arc bar 8 thereof of right tenon slot 4 is pressed into left tenon slot 2, because the spacing of circular arc bar 8 and plastic support riglet body 1 is slightly less than the spacing of hypotenuse 7 and plastic support riglet body 1, like this, in the female clip tenon 9 that female clip tenon 9 is clipped in left tenon slot 2 with the hypotenuse 7 and the circular arc bar 8 thereof of right tenon slot 4, cold contract self locking type plastic support riglet just has been compiled into auto-buckled type plastic support pipe, fasten by female clip tenon and male clip tenon self-clinching between the cold contract self locking type plastic support riglet, do not need welding.

Referring to Fig. 3 and Fig. 4, described male clip tenon is to be extended with the hook-shaped edges 3 that is formed with prominent beak 5 in its end at described plastic support riglet body 1 sidewall, is formed with the hook-type female clip tenon 6 that can hold described hook-shaped edges 3 between described hook-shaped edges 3 and described plastic support riglet body 1.

When cold contract self locking type plastic support riglet is compiled into auto-buckled type plastic support pipe, only need hook-shaped edges 3 and hook-type female clip tenon 6 make-ups, just cold contract self locking type plastic support riglet can be fastened as cold contract self locking type plastic support pipe auto-buckled type plastic support riglet two offsides.
