Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise. Furthermore, the terms "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 to 5, the present embodiment provides a screw with a drop-off prevention washer, which includes a head 1, a screw 2, and a washer 3.
The screw 2 comprises a polished rod section 21 and a threaded section 22, the polished rod section 21 being located between the head 1 and the threaded section 22.
The gasket 3 is sleeved on the polished rod section 21, the gasket 3 is connected with the polished rod section 21 in a sliding mode, and the moving range of the gasket 3 is the area between the head portion 1 and the threaded section 22.
In the present embodiment, the movement range of the washer 3 is limited between the head 1 and the threaded section 22, so that the washer 3 can be prevented from being removed from the screw, and the problem that the washer 3 is easily lost is solved. In addition, the screw is provided with the gasket 3, and the screw does not need to be sleeved manually in the assembling process, so that the assembling efficiency is improved.
In this embodiment, a specific embodiment is provided for trapping the washer 3 between the head 1 and the threaded segment 22:
the diameter of the inner ring of the washer 3 is larger than the diameter of the polished rod section 21 and smaller than the diameter of the thread of the threaded section 22. The threaded section 22 can limit the sliding of the gasket 3 and prevent the gasket 3 from falling off. In addition, the screw with the structure is manufactured by sleeving the gasket 3 on a bar material with a processed head part 1 and then processing the thread section 22.
A spring pad is arranged between the washer 3 and the head 1. After the spring pad is added, the spring pad can provide pressure for the screw, so that the friction force of the bolt is improved, and the anti-loosening effect is improved.
The upper surface of the head part 1 is provided with a straight or cross-shaped groove.
In this embodiment, another embodiment for limiting the washer 3 between the head 1 and the threaded segment 22 is provided:
the polished rod section 21 is provided with a rubber ring 4. The gasket 3 is positioned between the rubber ring 4 and the head part 1, the inner diameter of the rubber ring 4 is smaller than the diameter of the screw rod 2, and the outer diameter of the rubber ring 4 is larger than the inner diameter of the gasket 3.
Because the internal diameter of rubber circle 4 is less than the diameter of screw rod 2, under the effect of 4 elastic forces in rubber circle, rubber circle 4 can be fixed on screw rod 2, and in addition, the external diameter of rubber circle 4 is greater than the internal diameter of packing ring 3, so, can form spacing to packing ring 3.
The concrete structure of the rubber ring 4 is as follows:
the rubber ring 4 comprises an annular main body, and protruding structures 5 are arranged at two ends of the inner side of the annular main body.
The convex structure 5 is annular, and the outer side surface of the convex structure 5 is a bevel structure.
Through set up protruding structure 5 on rubber circle 4, at the screw in-process of screwing, the partial structure of rubber circle 4 can get into the clearance between packing ring 3 and the screw rod 2, perhaps the clearance between screw rod 2 and the screw hole, and then can improve the frictional force that the screw received, plays the locking purpose of screw.
In addition, the outer side surface of the protruding structure 5 is made into an inclined surface structure, so that the protruding structure 5 can conveniently enter a gap between the gasket 3 and the screw rod 2 or a gap between the screw rod 2 and the threaded hole.
The surface of the rubber ring 4 is rough. For example, the surface of the rubber ring 4 is provided with structures such as point-shaped bulges, and the friction force of the rubber ring 4 can be improved through the arrangement of the structures, so that the anti-loosening effect of the screw is improved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
