Abstract

The utility model relates to a pipeline protecting device, in particular to a protecting ring. The protecting ring comprises a protecting ring body and further comprises a protecting sleeve. The inner side of the top of the protecting ring body is provided with an annular groove, and the side face of the protecting ring body is provided with an annular fixing groove. The top of the protecting sleeve is bent inwards to form an annular cavity which is buckled on the top of the protecting ring body, the short side wall of the annular cavity is clamped into the annular groove, and the long side wall of the annular cavity is inserted into the fixing ring. According to the structure, impact of the front face, the impact of the side faces and the angular impact are all exerted on the protecting sleeve, the protecting sleeve has certain bearing force and elasticity, due to the fact that after two parts are combined, the buffering capacity is achieved, the force borne by the protecting sleeve can be greatly relieved, the strength of the whole protecting ring is improved, and in addition, the protecting ring is hard to damage. Even damage exists, only the protecting sleeve is damaged, and therefore the protecting ring can be recycled and reused. If damage exists, only the protecting sleeve needs to be replaced, and practical cost is reduced.

Description

A kind of protection ring

Technical field

The utility model relates to a kind of pipeline protection device, especially a kind of protection ring.

Background technology

Oil well pipe is these general name, and usual said oil pipe, sleeve pipe, drilling rod etc. all belong to oil well pipe.Oil well pipe is applied in the industry of various exploitations; be suitable for very extensive; but due to the special role of oil well pipe; therefore the precision that oil well pipe requires is very high; especially connecting portion, i.e. two statures of oil well pipe, in transportation, handling process; probably there will be damage, the effect of protection ring is exactly parts protecting nozzle position.

Due to main protection is internal thread or the external screw thread of the oil well pipe mouth of pipe; but in transportation or handling process; traditional protection ring; owing to being exactly the structure of a cast cock body; or cock is in pipeline opening; or be spun in pipeline opening; double thread is protected; but because the weight of oil well pipe is very heavy, the power of therefore colliding, pushing is very large, often can make protection ring damage; after protection ring damages; not only protection ring can not be recycled, and can cause protection ring to lose protective effect, thereby have influence on the protection to oil well pipe.

Utility model content

The purpose of this utility model is, provides that a kind of intensity is high, the protection ring of recoverable.

The utility model solves the technical scheme that its technical problem adopts: a kind of protection ring; comprise protection ring body; also comprise protective sleeve; the inside top of protection ring body is provided with a cannelure, and the side of protection ring body is provided with an annular holddown groove, and the top of protective sleeve curves inwardly; form an annular chamber; annular chamber is buckled in protection ring bodies top, and the shorter sidewall of annular chamber snaps in cannelure, and longer sidewall inserts in holddown groove.

This is arranged on and on protection ring body, puts a protective sleeve, protective sleeve exposes when in use, it to be so no matter positive shock, the shock of side is still the shock of angle, all on protective sleeve, protective sleeve itself possesses certain load-bearing and elasticity, owing to possessing buffer capacity after two component combinations, therefore can significantly reduce the suffered power of protective sleeve, not only improve the intensity of integral product, and be difficult to damage, even if having damage is also protective sleeve, therefore can reclaim, recycling, if there is damage, only need to change that protective sleeve is all right, reduce actual cost.

Of the present utility modelly further be set to: described annular chamber cross section is U-shaped, bending radian is 90 degree.

This arranges is arranged to 90 degree by bending radian, is because crooked radian is 90 while spending, stressed the most even, can make to greatest extent the average power of bearing collision of protective sleeve, can adapt to the shock of all directions, reaches best load effect.

Of the present utility modelly further be set to: the protection ring bodies top position corresponding with sweep is inclined-plane, and and protective sleeve inwall between form a cushion chamber.

This setting is provided with cushion chamber, and this is because in installing, protective sleeve can be installed more easily; forming cushion chamber, is to be directly delivered on the body of protection ring for fear of power, has a cushion chamber; play cushioning effect, protection protection ring body that can be higher.

Of the present utility modelly further be set to: also comprise protection piece, in obtuse triangle projection of lateral projections of protection ring body bottom as protection piece.

This is arranged on protection ring body side and arranges the protection piece of obtuse triangle; when stressed in side so, will produce resolution of forces; reduce the direct collision effect that acts directly on certain position on protection ring body; protection protection ring body does not damage because collide; can better protect oil well pipe, and convenient recycling.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the structural representation of the present embodiment;

Fig. 2 is the partial enlarged drawing of Fig. 1;

The specific embodiment

Known with reference to figure 1, a kind of protection ring of the utility model, comprise protection ring body 1, also comprise protective sleeve 2, the inside top of protection ring body 1 is provided with a cannelure 11, the side of protection ring body 1 is provided with an annular holddown groove 12, the top of protective sleeve 2 curves inwardly, form an annular chamber 21, annular chamber 21 is buckled in protection ring body 1 top, the shorter sidewall of annular chamber 21 snaps in cannelure 11, longer sidewall inserts in holddown groove 12, described annular chamber 21 cross sections are U-shaped, bending radian is 90 degree, the position corresponding with sweep, protection ring body 1 top is inclined-plane, and and protective sleeve 2 inwalls between form a cushion chamber 3, at obtuse triangle projection conduct protection piece 4 of lateral projections of protection ring body 1 bottom.

Obviously, above-described embodiment is only used to done giving an example is clearly described, and the not restriction to embodiment.To those of ordinary skill in the art, can also make other changes in different forms on the basis of the above description.Here without also giving exhaustive to all embodiments.And the apparent variation of being extended out thus or variation are still in protection domain of the present utility model.
