Abstract

The utility model relates to the technical field of fastening pieces, in particular to a special-shaped nut used for a cylinder cover when no screwing space is provided. The special-shaped nut comprises a nut body and a spanner gengon fixed at the axial end of the nut body, wherein the nut body adopts an integral structure with the spanner gengon, and the spanner gengon is a convex polygonal body or concave polygonal hole matched with a spanner. The special-shaped nut has the advantages of good applicability, simple structure, and convenient installation and disassembly.

Description

Special-shaped nut
Technical field
The utility model relates to technical field of fastening, especially a kind of special-shaped nut of cylinder head when not tightening the space.
Background technique
Cylinder head nut is mounted on the stud bolt of fastening cylinder head, is used for being connected of cylinder head and body.Nut one end has a boss, should will have an end of boss to contact with the cylinder head plain cushion during installation, otherwise can damage nut end face, and it is bad to be fitted in nut and cylinder head plane.
It is nervous or do not have the situation in spanner space that yet the spanner space can appear in nut when installing sometimes, too little as the nut spacing is installed, thereby make nut can't tighten in installation process or can't dismantle, and causes operation various, loses time.
The model utility content
The technical problems to be solved in the utility model is: for shortcoming and the deficiency that solves above-mentioned existence, provide a kind of spanner special-shaped nut of work easily.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of special-shaped nut has nut body and the spanner multi-arris body that is fixed in the axial end of nut body.
Further, for easy manufacturing, save the worker and make preface, nut body and spanner multi-arris body are structure as a whole.
For more convenient nut is loaded and unloaded, the spanner multi-arris body is evagination polygonal body or the indent polygonal hole that matches with spanner, and polygonal is quadrilateral or Hexagon or Octagon etc.
It is nervous or do not have under the situation in spanner space that the utility model is mainly used in the spanner space, is buckled on the spanner multi-arris body by spanner to be rotated, and realizes tightening and unclamping of nut.
The beneficial effects of the utility model are, special-shaped nut of the present utility model, and applicability is good, and is simple in structure, and installation and removal are convenient.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the overall structure plan view of Fig. 1;
Fig. 3 is an another kind of structural representation of the present utility model;
Fig. 4 is the overall structure plan view of Fig. 3.
Among the figure 1, nut body, 2, the spanner multi-arris body.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Special-shaped nut as shown in Figure 1 and Figure 2 has nut body 1 and is fixed in the spanner multi-arris body 2 of nut body 1 an axial end, and nut body 1 is structure as a whole with spanner multi-arris body 2, spanner multi-arris body 2 for the spanner indent polygonal hole that matches.
Special-shaped nut as shown in Figure 3, Figure 4 has nut body 1 and the spanner multi-arris body 2 that is fixed in nut body 1 an axial end, and nut body 1 is structure as a whole with spanner multi-arris body 2, and spanner multi-arris body 2 is the evagination polygonal body that matches with spanner.
When the utility model is implemented, spanner is buckled on the spanner multi-arris body 2, then nut is rotated, realize tightening or unclamping of spanner, made things convenient for nut dismounting and installation repeatedly, solved the little problem of nut installing space.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
