Abstract
The invention discloses a protecting device applied to petroleum machinery. The protecting device comprises a barrel, a plastic housing and a pressing cover. The plastic housing is composed of a top surface and a side wall and is in a circular truncated cone shape overall, a cavity is formed in the plastic housing, and the top surface is provided with a round hole. The top of the barrel is provided with a round channel through which the circle center axis of the round hole penetrates, the inner wall of the barrel is provided with an internal thread, and the outer wall of the barrel is attached to the inner wall of the plastic housing. The pressing cover is in a T shape, and the lower end of the pressing cover sequentially penetrates through the round hole and the channel and extends into the barrel. The barrel and the plastic housing are arranged, the internal thread arranged in the barrel is matched with an external thread of a petroleum machinery workpiece, and the outer wall of the barrel is in close fit with the inner wall of the plastic housing, so that under the situation that the pressing cover is screwed tightly, when fierce collision or friction occurs, the plastic housing has definite deformability, acting force on the barrel can be reduced, and the protecting effect on the thread of the petroleum machinery workpiece is enhanced.
Description
Technical field
The present invention relates to petroleum machinery equipment, be specifically related to a kind of preventer being applied to petroleum machinery.
Background technology
In petroleum machinery workpiece; workpiece has external screw thread greatly; the intensity at screw thread place is poor; in transportation; easily because situations such as colliding, compress and rub against is by thread damage, screw thread is once be damaged, and workpiece will be impacted when using; even workpiece is scrapped, so the protection of workpiece female thread is just extremely important.
The external screw thread of existing petroleum machinery workpiece is typically via arranging a shield body coordinated with workpiece external screw thread, and shield body adopt be rigid material, the external screw thread of petroleum machinery workpiece is bigger with the female thread interaction force of shield body, the external screw thread easily making petroleum machinery workpiece deforms, and still can affect the precision of petroleum machinery workpiece.
Summary of the invention
The technical problem to be solved is: existing petroleum machinery protecting cover easily makes the external screw thread of mechanical workpieces deform, and affects the service precision of petroleum machinery workpiece.A kind of preventer being applied to petroleum machinery is now provided, adopt cylinder, plastics cover body, compress cover body structure, the female thread adaptive with petroleum machinery workpiece external screw thread is set at cylinder inboard wall, solves the technical problem that in existing shield body structure, external screw thread is easily deformed.
The present invention is achieved through the following technical solutions:
A kind of preventer being applied to petroleum machinery, including cylinder, plastics cover body, compresses lid, and described plastics cover body is end face and sidewall composition, and overall one-tenth is round table-like, and it is internal is cavity shape, and end face is provided with circular hole；The top of described cylinder is provided with the circular channel that the circle core shaft with circular hole runs through, and the inwall of cylinder is provided with female thread, and the inwall of the outer wall of cylinder and plastics cover body is fitted；Described compression lid is T-shaped, and the lower end compressing lid sequentially passes through circular hole, passage, and extends in cylinder.
Adopt technique scheme, after female thread in middle cylinder body of the present invention coordinates with the external screw thread of petroleum machinery workpiece, the outer wall of the outer wall of cylinder and plastics cover body fits tightly, the plastic material that plastics cover body itself adopts, having good pliability, collide at petroleum machinery workpiece, when extruding and rub strong, plastics cover body itself has certain deformability, can reduce the active force to cylinder, and then reduce the active force being arranged in cylinder mechanical workpieces.Compressing the lid circular hole by being arranged on plastics cover body, the passage of cylinder is inserted into inner barrel, and cylinder, plastics cover body are fastened, it is prevented that plastics cover body, cylinder rotate against and mechanical workpieces is damaged.
Further, in order to better realize the present invention, it is provided with in described cylinder and the cavity adaptive with external thread petroleum machinery workpiece.During installation, externally threaded for band petroleum machinery workpiece is placed in cavity.Described plastics cover body is provided with tank filler sleeve.The sidewall of described cylinder is provided with tank filler sleeve.Machine oil can be injected by tank filler sleeve to the external screw thread of petroleum machinery workpiece to maintain.
Further, in order to better realize the present invention, described cylinder is rigid canister.Described cylinder is the tube structure of interior circular diameter and circular channel equal diameters.Arranging of tube structure is mainly easy to rotate compression lid, and overall structure is fixed.
Further, in order to better realize the present invention, described compression lid is hex bolts, it is possible to directly assemble by conventional tool such as spanners, it is simple to operation.
The present invention compared with prior art, has such advantages as and beneficial effect:
The present invention is by arranging cylinder, plastics cover body; the female thread structure arranged in cylinder is adaptive with the external screw thread of petroleum machinery workpiece; and the inwall of the outer wall of cylinder and plastics cover body fits tightly; when compressing lid and screwing; there is fierceness collision, friction; plastics cover body has certain deformability, can reduce the active force to cylinder, strengthens the protective effect to petroleum machinery workpiece screw thread.
Accompanying drawing explanation
Accompanying drawing described herein is used for providing being further appreciated by the embodiment of the present invention, constitutes the part of the application, is not intended that the restriction to the embodiment of the present invention.In the accompanying drawings:
