Abstract
The utility model discloses a pipe joint locking sealing sleeve, which is composed of a pipe body. A tooth ring 2 is arranged in the pipe body and a through groove 3 is arranged on the pipe wall. The cross section shape of the pipe body is made into a mold. Metallic materials are processed into long strip shapes by using an extrusion method or a press and extending method. Then the long-strip-shaped metallic materials are cut according to needed the peripheral lengths and then are rolled into cylindrical shapes and tooth rings are formed inside. The through grooves are formed on joints on both sides. Anti pulling force of the pipe joint is increased, and thus the sealing property of pipe elements are better, and the utility model has the advantages of simple processing technology, zero material consumption and quality assurance.
Description
The utility model belongs to a kind of pipe fitting Sealing.
In Chinese patent application 97226373, the locking sleeve internal diameter of pipe fitting is cylindric, inner wall smooth, and friction factor is little, and its coupling mechanism force is limited, and anti-pull-out force is low.
The purpose of this utility model is: provide a kind of pipe joint locking sleeve that can increase coupling mechanism force, improve anti-pull-out force, to solve the deficiencies in the prior art.
The utility model is achieved in that it is made up of body (1), and ring gear (2) is arranged in body (1), and groove (3) is arranged on its tube wall.
The utility model has compared with prior art improved the anti-pull-out force of pipe fitting joint greatly, thereby has made the pipe fitting better tightness, and processing technology is simple, no spillage of material, and can guarantee quality of product, be fit to produce in batches.
Accompanying drawing 1 is a structural drawing of the present utility model.
Embodiment of the present utility model: the sectional shape with body (1) is made mould, with extrusion or rolling process metal material processing is become strip, cut off according to required circumferential length again, be rolled into cylindric, form ring gear (2) in it, the joint, both sides forms road groove (3).So promptly make locking sleeve.
Claims (1)
1, a kind of pipe joint locking sleeve, it is made up of body (1), it is characterized in that: ring gear (2) is arranged in body (1), groove (3) is arranged on its tube wall.
