The technical problem to be solved by the utility model is realized by adopting the following technical scheme:

the utility model provides a ring gear tensile takes off type pipe connector which characterized in that: including adjustable clamp body, ring gear and rubber circle, the strap of adjustable clamp body sets up the structure that keeps off the eaves for both ends, keeps off eaves department at two and all is provided with the ring gear, is provided with the rubber circle between two ring gears, and the lower extreme butt of each ring gear is in the root department that keeps off the eaves, and the upper end butt of each ring gear is on the rubber circle, the highly thickness that is greater than the rubber circle of ring gear.

And, adjustable clamp body constitute by strap, through hole axle, threaded shaft, cross bridge plate and bolt, the both ends of strap are all turned over and are welded into the cover barrel shape, wear to be equipped with through hole axle and threaded shaft in the inflection sleeve at both ends respectively, cross the bridge plate and install between strap both ends, cross the bridge plate and freely stretch out and draw back with the other end with strap one end is fixed, the bolt passes by the epaxial perforation of through hole, threaded connection is in the threaded shaft's threaded hole department, the strap be the structure that the middle part set up perpendicularly and keep off the eaves.

And the gear ring is formed by bending a steel belt, the head parts of the two ends of the gear ring are mutually overlapped, and sawteeth are uniformly distributed at intervals on the upper end of the steel belt.

Moreover, the rubber ring is of a structure that convex edges are arranged on the inner wall at intervals.

And the inner wall of the strap is provided with a convex concave-convex structure matched with the outer wall of the rubber ring.

The utility model has the advantages and positive effects that:

1. according to the toothed ring pull-off resistant pipeline connector, the traditional clamp with the toothed ring with the non-adjustable caliber is designed to be adjustable, and when the toothed ring pull-off resistant pipeline connector is used, the rubber ring can be replaced according to the caliber of a pipeline to be connected, so that the applicability of the connector is enhanced, and the storage cost of the connector is reduced; the sealing of the connector is completed by simultaneous deformation of the gear ring and the rubber ring, when the connector is fastened, the connector is extruded by a pipeline, firstly, the gear ring is deformed to a higher degree, and because the gear ring is obliquely arranged, damage to a ring body caused by direct pressure is avoided; the tooth ring has the capability of self-adapting to the size of force, so that the pull-off resistance of the tooth ring is enhanced.

2. This ring gear tensile takes off type pipe connector designs for the bellied concave-convex structure of adaptation rubber circle through the inner wall with the strap, and protection rubber circle non-deformable is first, and second further strengthens sealed effect.

3. The tooth ring pull-off resistant pipeline connector is scientific and reasonable in design, has the advantages of adjustability, convenience in use, strong sealing performance and easiness in implementation, and is highly innovative.
