Fig. 1 is a schematic structural view of an automatic clamping screw provided in an embodiment of the present invention;
the labels in the above figures are: 1. nut, 12, slot, 13, clamping washer, 131, cutting part, 132, base part, 133, pressing part, 2, stud, 21, screw thread.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, an automatic clamping screw has:
the head of the nut is provided with a slot;
the stud is connected with the bottom of the nut, and the stud and the nut are of an integrated structure; the end part of the stud is a pointed end, and the periphery of the stud is provided with threads;
the clamping washer is annular and comprises a base part and a pressing part, the base part and the nut are of an integrated structure, the end surface of the pressing part is higher than that of the base part, the clamping washer is provided with a cutting part, and the cutting part separates the pressing part and the base part; when the force is not applied, a gap is reserved between the pressing part and the nut. After the tightening, the pressing part is attached to the nut to form a pressing force.
The slot is a straight slot or a cross slot.
The clamping washer is spiral. The pressing force is achieved by a spiral shape, and after the screw is tightened, the clamping washer is pressed into a planar shape to form a pressing force.
The nut is internally provided with a groove for accommodating the clamping washer, and the depth of the groove is smaller than the thickness of the clamping washer. The limiting washer can be used for limiting the washer and can also achieve the clamping effect.
After adopting foretell structure, joint packing ring and nut formula structure as an organic whole need not install the packing ring in addition, can not neglected to adorn the packing ring, and the fastening is reliable.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
