Abstract
The utility model relates to a pipe protection device, in particular to an oil well pipe protection ring. The oil well pipe protection ring comprises a plug body and a protection ring body, the plug body and the protection ring body are integrally arranged, the oil well pipe protection ring further comprises an inner supporting sleeve, the periphery of the upper portion of the plug body outwards protrudes to form the protection ring body, and the inner supporting sleeve is inversely buckled in the plug body. According to the structure, the inner supporting sleeve is arranged in the plug body, the bearing force strength of the oil well pipe protection ring is improved, the oil well pipe protection ring is protected from damage, convenience is brought to reutilization, better protection is provided for an oil well pipe, when the periphery bears collisions or extrusion, the inner supporting sleeve is stressed to be deformed, stress of the protection ring is shared, and the protection ring body and the inner supporting sleeve are not prone to being damaged.
Description
Technical field
The utility model relates to a kind of pipeline protection device, especially a kind of oil well pipe 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 degree of 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 be the negative 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, therefore insufficient strength, in transportation and handling process or often damage.
Utility model content
The purpose of this utility model is, provides a kind of intensity oil well pipe protection ring high, rational in infrastructure.
The utility model solves the technical scheme that its technical matters adopts: a kind of oil well pipe protection ring; comprise cock body, protection ring, cock body and protection ring are wholely set, and also comprise interior support set; cock body top surrounding outwardly convex forms protection ring, and interior support set tips upside down in cock body.
This is arranged on an interior support set is set in cock body; increase load intensity of the present utility model; protection oil well pipe protection ring is not damaged; be convenient to recycling; provide better protection to oil well pipe, in being circumferentially collided or pushing, interior support set stress deformation; share the stressed of protection ring, protection ring and interior support set are not easy to damage more.
Of the present utility modelly further be set to: also comprise the load-bearing piece of arc, the load-bearing piece of arc is fixed in cock body, and the edge of load-bearing piece and cock body inwall are wholely set, and interior support set tips upside down on load-bearing piece.
This is arranged on load-bearing piece is set in cock body; not only internally support set has certain supporting role; because its edge and cock body inwall are wholely set, cock body is in stressed, because load-bearing piece is arc like this; not only possesses supporting role; strengthen the intensity of cock body, and possess elasticity, after stressed; keep the best protection shape of cock body, better protect oil well pipe.
Of the present utility modelly further be set to: also comprise card pipe, card pipe box is located in cock body, card pipe bottom inwardly protruding forms a snap ring, and interior support set top is provided with snap fit or the bulge loop with snap ring adaptation, snap fit or bulge loop and snap ring clamping.
This is arranged on and a card pipe is set in cock body coordinates with interior support set; not only can fix the position of interior support set; increased one deck body simultaneously; in structure, increase the intensity of product; and prevent that interior support set from sliding or jumping out in cock body; under stressing conditions, this structure has also possessed the function of sharing pressure, has also protected whole product.
Of the present utility modelly further be set to: on protection ring, be also provided with U-shaped dividing potential drop mouth.
This is arranged on dividing potential drop mouth is set on protection ring; in order to protect protection ring not damage when stressed; if there is no dividing potential drop mouth; so in being clashed into or being pushed; protection ring is easily subject to stress and breaks; there is dividing potential drop mouth, can actv. have reduced the impact of stress, improved the limit stressing conditions of protection ring.
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;
The specific embodiment
Known with reference to figure 1, a kind of oil well pipe protection ring of the utility model, comprise cock body 1, protection ring 2, cock body 1 is wholely set with protection ring 2, also comprise interior support set 3, cock body 1 top surrounding outwardly convex forms protection ring 2, interior support set 3 tips upside down in cock body 1, the load-bearing piece 4 of arc is fixed in cock body 1, the edge of load-bearing piece 4 and cock body 1 inwall are wholely set, interior support set 3 tips upside down on load-bearing piece 4, card pipe 5 is set in cock body 1, card pipe 5 bottom inwardly protrudings form a snap ring 51, interior support set 3 tops are provided with the bulge loop 31 with snap ring 51 adaptations, bulge loop 31 and snap ring 51 clampings, bulge loop 31 herein can be replaced by snap fit, can certainly use other position limiting structure, on protection ring 2, be also provided with U-shaped dividing potential drop mouth 21.
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.
