Description
Technical field
This utility model belongs to mechanical attachment technique for fixing field, is specifically related to the improvement to sunk screw anti-skid washer.
Background technology
Sunk screw is used in a large number, due to the screw of sunk screw at present in every field such as machine-building, equipment installations
Head is cone surface shape, so common spring washer cannot use, therefore sunk screw does not all have reliable locking measure, along with
Equipment or the use of product, screw gradually can loosen, if checking discovery not in time, influences whether the peace of equipment and personnel
Entirely, it is therefore desirable to a kind of packing ring that can reliably prevent sunk screw locking.
Utility model content
This utility model overcomes the deficiencies in the prior art, it is provided that a kind of pad that can effectively prevent sunk screw from loosening
Circle, to meet product or the requirement of equipment fastening security.
In view of the problems referred to above of prior art, according to disclosed in this utility model aspect, this utility model uses
Techniques below scheme:
A kind of sunk screw anti-skid washer, it is the revolving parts of a kind of spring material, and described anti-skid washer is cross section
For the annular cones body (1) of inverted trapezoidal, the trapezoidal base, cross section of anti-skid washer and hypotenuse angle are 30 °, annular cones body (1)
Annular thickness is c, c=0.3～0.6mm, and annular cones body (1) has the internal radius Φ A ＞ 2mm of small diameter, annular circle
Cone (1) sidepiece has groove (3), and groove (3) a width of b, b are 1～3mm, and the both sides of trough rim have lateral shift a, a be 0.5～
1.5mm, this lateral shift is prevented from sunk screw and loosens.
By the design of lock washer, fill up sunk screw and the blank of locking measure has been installed, this anti-loosening gasket structure letter
Single, easy to make, use flexibly, can effectively prevent that sunk screw from occurring during using loosen, Problem of Failure, raising sets
Standby safety in utilization, reliability.

Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further detail, but embodiment of the present utility model is not
It is limited to this.
Seeing Fig. 1, a kind of sunk screw anti-skid washer, it is the revolving parts of a kind of spring material, described slipmat
Enclosing as annular cones body (1) that cross section is inverted trapezoidal, the trapezoidal base, cross section of anti-skid washer and hypotenuse angle is 30 °, annular circle
The annular thickness of cone (1) is c, c=0.3～0.6mm, and annular cones body (1) has the internal radius Φ A ＞ of small diameter
2mm, annular cones body (1) sidepiece has groove (3), and groove (3) a width of b, b are 1～3mm, and the both sides of trough rim have lateral shift
A, a are 0.5～1.5mm, and this lateral shift is prevented from sunk screw and loosens.
Using method of the present utility model is: by gasket sleeve on sunk screw (5), make the internal conical surface (6) of packing ring with
The head of screw conical surface (5a) laminating of sunk screw (5), is then fastened on sunk screw (5) in screw hole (8), makes outside packing ring
The conical surface (9) is deformed with taper hole (7) and fits, owing to deformation makes the lateral shift of the groove (3) of packing ring to the head of screw conical surface
(5a) there is a bigger pressure all the time, thus improve frictional force radially, make sunk screw (5) to loosen, thus reach
Arrive locking purpose.
This utility model simple in construction, making are easily, easy to use, and sunk screw can be coordinated to be widely used in each side
Face.
