Abstract
The invention discloses a mounting and dismount groove of a steel-plastic internal thread protector which is used for protecting external threads of tube heads of steel tubes. The mounting and dismount groove comprises a cap body formed through injection. The cap body is in a shape of a cylinder. A built-in steel ring is arranged inside the cap body. A cap body upper edge is arranged at the top of the cap body. A mounting and dismount groove body is formed in the cap body upper edge. A non-return edge protruding out of the outer wall of the cap body is arranged on the lower portion of the cap body upper edge. A thread is formed in the position, located at the bottom of the non-return edge, of the outer wall of the cap body. The top of the thread makes contact with the non-return edge. The bottom of the thread and the opened end of the bottom of the cap body are separated by a distance to form a positioning zone. The positioning zone forms a 90-degree chamfer with the plane of the opened end of the bottom of the cap body. The mounting and dismount groove has the beneficial effects that the protector can be mounted and dismounted conveniently and labor is saved by the adoption of the mounting and dismount groove structure in the technical scheme.
Description
Technical field
The present invention relates to a kind of protector for the protection of steel pipe tube head outside thread.
Background technology
Steel pipe, in transportation, very easily causes damage to pipe end outside thread, in order to protect tube head outside thread, generally at pipe end suit pipe cap, is also protector.Protector adopts with pipe end and is threaded, and because protector is not of uniform size, and when protector is connected with pipe end, requires compact siro spinning technology, and therefore existing protector dismounting is required great effort very much.
Summary of the invention
The invention provides a kind of dismounting groove of steel plastic internal-thread protector, make the dismounting of protector become laborsaving.
In order to achieve the above object, the technical scheme that the present invention takes is:
A kind of dismounting groove of steel plastic internal-thread protector, it is characterized in that: comprise injection molded cap body, cap body cylindrically, cap body inside is provided with built-in steel ring, edge on cap body is provided with at the top of cap body, along being provided with dismounting groove on described cap body, described cap body is provided with along lower position the non-return edge of protruding the external wall of cap, described non-return is provided with screw thread along the external wall of cap of bottom, described threaded top and non-return are along contacting, segment distance of being separated by with cap body bottom open end bottom it forms positioning area, described positioning area and cap body bottom opening transverse plane are provided with 90 ° of chamferings.
The invention has the beneficial effects as follows, owing to have employed dismounting groove structure of the present invention, make protector easy accessibility, save manpower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1. edge on cap body; 2. built-in steel ring; 3. cap body; 4. screw thread; 5. non-return edge; 6. dismounting groove; 7. positioning area.
Detailed description of the invention
From accompanying drawing, the present invention includes injection molded cap body 3, cap body 3 cylindrically, cap body 3 inside is provided with built-in steel ring 2, be provided with on cap body along 1 at the top of cap body 3, described cap body is provided with dismounting groove 6 along 1, described cap body is provided with the non-return of protrusion cap body 3 outer wall along 5 along 1 lower position, described non-return is provided with screw thread 4 along the external wall of the cap bottom 5, described screw thread 4 top contacts along 5 with non-return, segment distance of being separated by with cap body 3 bottom open end bottom it forms positioning area 7, described positioning area 7 is provided with 90 ° of chamferings with cap body bottom opening transverse plane.Owing to adopting bottom chamfer, make tin hat be easy to insert pipe end inner, and cross transition region 7, make the screw thread 4 of pipe end contact protection cap, use pipe to be stuck in dismounting groove 6 and rotate, tin hat can be screwed in pipe end.During dismounting, rotate round about and can pull down.
