Abstract
The utility model provides a kind of hangnail sealed type casing tube screw thread protectors, is provided with the hangnail that 3-4 ring cross-section is right angle trigonometry shape on the inwall of one end of threading protectors body, and the drift angle of hangnail is 20~30 degree angles, and the height of hangnail is 3mm; On the other end inwall of threading protectors body, be carved with a circle rectangular channel, it is rectangle oil resistant silica gel sealing ring that cross section is housed in rectangular channel.Effect of the present utility model is that this hangnail sealed type casing tube screw thread protectors front end is provided with hangnail; rear end adopts oil resistant silica gel sealing ring; the stubborn gap that connects rear rear and front end of protector and screw thread is all sealed; by casing threads and surrounding environment isolation; be among airtight environment; stop the seepage of dope, made casing threads all the time among the protection of dope.Blocked simultaneously rainwater or and airborne moisture immerse the path of casing threads, avoided rainwater or and the erosion of airborne moisture double thread and the screw-thread rust that causes.
Description
Technical field
The utility model relates to a kind of hangnail sealed type casing tube screw thread protectors.
Background technology
Threading protectors is the block of protecting screw thread and sealing when loading and unloading, transport and store.I stock's of company sleeve pipe is usually found screw-thread rust and oil impregnate phenomenon in the time that finished product is patrolled.Thinking by analysis that traditional threading protectors just twists to fetch by screw thread plays a protective role, but can not prevent dope seepage, can not prevent that the moisture of rainwater and damp air is to the erosion of screw thread.
The protector of ordinary construction is just twisted to fetch by screw thread and is played a protective role, and pipe end and the outside face of protector and sleeve pipe exist gap.Deposit the sleeve pipe of certain hour, the dope on screw thread will leak out along bushing outer surface in End play from protector, makes dope lose the protective effect of double thread.Simultaneously rainwater or and airborne moisture can be from the gap middle sleeve screw thread of protector rear and front end, double thread corrodes, and causes casing threads corrosion, serious screw thread is scrapped.
Summary of the invention
The purpose of this utility model is to provide a kind of hangnail sealed type casing tube screw thread protectors, effectively prevents casing threads corrosion and dope seepage.
For achieving the above object, the technical solution adopted in the utility model is to provide a kind of hangnail sealed type casing tube screw thread protectors, wherein: on the inwall of one end of threading protectors body, be provided with the hangnail that 3-4 ring cross-section is right angle trigonometry shape, the drift angle of hangnail is 20~30 degree angles, and the height of hangnail is 3mm; On the other end inwall of threading protectors body, be carved with a circle rectangular channel, it is rectangle oil resistant silica gel sealing ring that cross section is housed in rectangular channel.
The degree of depth of described rectangular channel is identical with length and the width of rectangle oil resistant silica gel sealing ring with width.
Effect of the present utility model is that this hangnail sealed type casing tube screw thread protectors front end is provided with hangnail; rear end adopts oil resistant silica gel sealing ring; the stubborn gap that connects rear rear and front end of protector and screw thread is all sealed; by casing threads and surrounding environment isolation; be among airtight environment; stop the seepage of dope, made casing threads all the time among the protection of dope.Blocked simultaneously rainwater or and airborne moisture immerse the path of casing threads, avoided rainwater or and the erosion of airborne moisture double thread and the screw-thread rust that causes.

Detailed description of the invention
By reference to the accompanying drawings structure and the use of hangnail sealed type casing tube screw thread protectors of the present utility model are illustrated.
As shown in Figure 1, 2, hangnail sealed type casing tube screw thread protectors of the present utility model, on the inwall of one end of threading protectors body 1, being provided with 3-4 ring cross-section is the hangnail 3 of right angle trigonometry shape, and the drift angle of hangnail 3 is 20~30 degree angles, and the height of hangnail 3 is 3mm; On the other end inwall of threading protectors body 1, be carved with a circle rectangular channel, it is rectangle oil resistant silica gel sealing ring 2 that cross section is housed in rectangular channel.
The degree of depth of rectangular channel is identical with length and the width of rectangle oil resistant silica gel sealing ring with width.
As shown in Figure 1, 2, the utility model, according to the size of the specification of threading protectors body 1, arranges the hangnail 3 of 3-4 circle right angle trigonometry shape in the front inner wall of threading protectors body 1, drift angle 20~30 degree of hangnail 3, and the height of hangnail 3 is 3mm.When hangnail in the front inner wall of threading protectors body 13 and the screw thread of casing threads are twisted while connecing; because the height of hangnail 3 is 3mm; make the internal diameter of hangnail 3 be less than the external diameter of sleeve pipe; hangnail 3 is subject to casing threads pushing without threaded sleeve outside face below; again because the drift angle of hangnail 3 is 20~30 degree angles; hangnail 3 adopts plastic material; hangnail 3 is squeezed the certain elastic deformation of generation and recedes; so contact with the threadless intimate of sleeve pipe, sealed the gap between sleeve pipe and protector front end.
After hangnail sealed type casing tube screw thread protectors and screw thread are twisted and connect, the rectangle oil resistant silica gel sealing ring 2 of threading protectors body 1 rear end closely cooperates with the end face of sleeve pipe, has sealed the gap between sleeve pipe pipe end and protector 1 rear end.
Hangnail sealed type casing tube screw thread protectors is isolated casing threads place and surrounding environment through the sealing of rear and front end; and be among airtight environment; both stoped the outside seepage of dope; blocked rainwater or and the inside intrusion of airborne moisture; thereby prevent casing threads corrosion, effectively protection sleeve screw thread.
