Abstract
The utility model relates to a bolt special for a flange of a degassing tank access hole. The bolt special for the degassing tank access hole comprises a threaded rod body and a hexagonal end part of the bolt and has the innovative point that one corner of the hexagonal end part of the bolt is cut off to form an inward arc-shaped concave side. The bolt special for the degassing tank access hole has the advantages that during use, the hexagonal end part of the bolt is positioned on the lower end surface of the flange of the access hole and is limited by tightly adhering to the neck part of the flange of the access hole through the inward arc-shaped concave side; and a spanner is not required to clamp the hexagonal end part of the bolt, so that the bolt special for the degassing tank access hole is convenient and quick to disassemble and assemble.
Description
Technical field
The utility model relates to a kind of bolt, particularly a kind of degassing tank access opening special bolt.
Background technique
Degassing tank access opening flange is when connecting, and its bolt hex end is positioned at the access opening lower end surface, and the threaded stem body portion is locked with nut thread after being upward through flange.The shortcoming of this kind bolt arrangement is: when dismounting, need clamp the hex end of bolt, prevent its transfer by instruments such as spanners, and because access opening position relation, spanner is difficult to stretch into its lower end surface and clamps hex end.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of degassing tank access opening special bolt of easy disassembly.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of degassing tank access opening flange special bolt, comprise the screw thread body of rod and hex end thereof, its innovative point is: the hex end of described bolt is excised a dihedral and is become an arc concave edge.
Advantage of the present utility model is: during use, the hex end of bolt is positioned at the lower end surface of access opening flange, utilizes its arc concave edge to be close to access opening flange neck and carries out spacingly, need not to use spanner to clamp hex end, and is convenient to disassembly.
Description of drawings
Fig. 1 is the utility model degassing tank access opening special bolt end plan view;
Fig. 2 is the utility model type degassing tank access opening special bolt user mode figure.
Embodiment
As shown in Figure 1, 2, comprise the screw thread body of rod 1 and hex end 2 thereof, this hex end is excised a dihedral and is become an arc concave edge 21.During use, the hex end 2 of bolt is positioned at the lower end surface of access opening flange 3, utilizes its arc concave edge 21 to be close to access opening flange 3 necks and carries out spacingly, and it is promptly dismantled and assembled to need not to use spanner to clamp hex end 2.
