Description
Technical Field
The utility model relates to a steel pipe production auxiliary fixtures technical field, concretely relates to thread protector for steel pipe.
Background
The steel pipe is very easily to cause the harm to the pipe end in the transportation, in order to protect the pipe end, generally can be at pipe end suit pipe cap, also promptly the protector. Especially for the steel pipe that both ends were equipped with the screw thread, the protector still can be equipped with steel pipe assorted screw thread, and current steel pipe is with screw thread protector, generally steel-plastic structure, and the crashproof performance of main emphasis protective sheath, the performance that waterproof, prevent grey, grease proofing lacquer got into is not good enough. The application aims at providing a thread protector for steel pipe that waterproof dustproof effect is good.
Disclosure of Invention
The utility model aims at overcoming the above-mentioned not enough and providing a thread protector for steel pipe of prior art, this protector waterproof dustproof effect is better.
The technical scheme of the utility model is that: a thread protector for a steel pipe comprises a protector main body and a sealing part, wherein the protector main body is cylindrical, one end of the protector main body is closed, the other end of the protector main body is open, and threads matched with the steel pipe are arranged on the inner wall of the protector main body; the sealing portion is arranged at the opening of the protector main body, the sealing portion is integrally annular, the inner diameter of the ring is gradually reduced from one end connected with the protector main body to the other end, and finally the inner diameter of the other end is slightly smaller than the outer diameter of the steel pipe.
Further, the thickness of the sealing portion is gradually thinner from one end to the other end along the direction of the central axis, and the thick end is connected with the protector main body, so that the thinner end of the sealing portion is more easily deformed.
Further, the cross section of the sealing portion may be triangular or quadrangular, and the side of the cross section pattern located inside the ring is formed at an angle of 0 to 5 ° with respect to the horizontal line such that one end of the sealing portion is inclined toward the inside of the ring.
Further, the sealing part is provided with an annular bulge which has the function of strengthening the sealing performance.
Furthermore, the bulge is arranged on the inner side of the ring of the sealing part and is close to one end connected with the protector main body.
Preferably, the projection is integrally formed with the seal portion, and more preferably, the seal portion is integrally formed with the protector main body.
Furthermore, the sealing part and the protector main body are made of materials with certain toughness and elasticity, such as plastic materials, so that the sealing part has good deformation capacity and toughness and can be used for multiple times.
In other technical schemes, the sealing part and the protector main body are also detachably connected, when the sealing part is worn, the sealing part can be only replaced, and the protector main body can be continuously and repeatedly used.
The utility model has the advantages that: the utility model discloses a thread protector is provided with the sealing, and the sealing adopts flexible material to make, and the internal diameter of ring reduces to the other end from the one end of being connected with the protector main part gradually for the internal diameter of the sealing other end is less than the steel pipe, and when installing on the steel pipe, the sealing takes place deformation under the extrusion of steel pipe, closely meets with the steel pipe and realizes good sealed effect, the utility model discloses a when the protector uses on having certain tapered steel pipe, has more the superiority for the effect of ordinary protector.

Detailed Description
The present invention will be described in further detail with reference to specific embodiments, wherein components or systems not specifically described in the embodiments are known in the art. In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "longitudinal", and the like, indicate orientations or positional relationships based on the orientations or positional relationships illustrated in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
Examples
As shown in fig. 1-4, the present embodiment is a thread protector for steel pipes, which includes a protector main body 1 and a sealing part 2, wherein the protector main body 1 is cylindrical, one end of the protector main body is closed, the other end is open, and the inner wall of the protector main body 1 is provided with threads matched with a steel pipe 3; sealing portion 2 sets up at protector main part 1 opening part, and sealing portion 2 is whole for cyclic annular, and the internal diameter of ring reduces gradually from the one end of being connected with protector main part 1 to the other end, finally makes the internal diameter of the other end slightly less than the external diameter of steel pipe 3. The thickness of the sealing portion 2 is thinner from one end to the other end in the direction of the central axis, and the thick end is connected with the protector body 1, so that the thinner end of the sealing portion 2 is more easily deformed.
In this embodiment, the cross section of the seal portion 2 is triangular, and the angle (denoted as a) between the side of the triangular cross section located inside the ring and the horizontal line is 0 to 5 °, so that one end of the seal portion 2 is inclined toward the inside of the ring.
In this embodiment, the sealing part 2 is provided with an annular protrusion 21, the protrusion 21 has a function of enhancing sealing performance, the protrusion 21 is provided inside the ring of the sealing part 2 and near one end connected to the protector main body 1, the protrusion 21 and the sealing part 2 are integrally formed, and the sealing part 2 and the protector main body 1 are integrally formed.
