A kind of special pin member
Technical field
The utility model belongs to technical field of electronic products, and in particular to a kind of special pin member.
Background technology
, it is necessary to be used as the fixation of position between part using pin member in electronic control product structure.Traditional pin member
Connection space is larger, because robot components construction is intensive, traditional part is improved, to reduce space hold.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of simple in construction, space-consuming few special
Pin member.
To achieve these goals, the utility model is to realize by the following technical solutions:
A kind of special pin member, it includes diameter 4-5mm axle, one end of the axle set hemisphere or ball-crown body with
One end of the axle is connected as a single entity, and the axle sets annular knurl close to the outer surface of the other end, and the annular knurl is and diameter parallel
Some grooves are formed, and the inner side of the annular knurl sets ring groove, the ditch groove width 1.5mm.
Beneficial effect:
The utility model one end is arranged to cambered surface, and the other end sets annular knurl, is easy to the installation with part to be located by connecting, makes zero
Part construction is more dense, and space-consuming is less.
Brief description of the drawings
Describe the utility model in detail with reference to the accompanying drawings and detailed description;
Fig. 1 is structural representation of the present utility model.
Embodiment
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below
With reference to embodiment, the utility model is expanded on further.
Embodiment
Reference picture 1, the utility model include diameter 4-5mm axle 1, and one end of the axle 1 sets hemisphere 2 and institute
The one end for stating axle 1 is connected as a single entity, and the axle 1 sets annular knurl 3 close to the outer surface of the other end, and the annular knurl 3 is and diameter parallel
Some grooves form, the inner side of the annular knurl 3 sets ring groove 4, the 4 wide 1.5mm of groove.
As a further improvement, one end of the axle 1 sets one end of ball-crown body and the axle to be connected as a single entity.
The utility model one end is arranged to cambered surface, and the other end sets annular knurl, is easy to the installation with part to be located by connecting, makes zero
Part construction is more dense, and space-consuming is less.
