Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a protective equipment screw for orthopedic surgery nursing, includes double-screw bolt 1 and spiral shell top 2, integrated into one piece between double-screw bolt 1 and the spiral shell top 2, and thread has been seted up to double-screw bolt 1's lateral wall, and the upper surface welded fastening of spiral shell top 2 is equipped with twists ring 3, and four hole grooves have been seted up to the border department of 2 lower surfaces on spiral shell top, and the fixed mounting of hole inslot has spring 4, and spring 4 extends out the one end in hole groove and the last fixed surface of packing ring 5 is connected, and the lateral wall of double-screw bolt 1 is located.
In this embodiment (please refer to fig. 2), a cavity 6 is formed inside the stud 1; through the arrangement of the cavity 6, the production materials of the stud 1 are reduced on the premise of keeping the appearance of the stud 1 unchanged, and the production cost is saved.
In this embodiment (see fig. 3), the upper surface and the lower surface of the gasket 5 are both provided with a frosted layer 7; through the setting of dull polish layer 7, improve the gasket 5 and respectively with the protective equipment and the screw top 2 contact's frictional force, further prevent that stud 1 from producing not hard up.
In this embodiment (see fig. 4), the outer side wall of the stud 1 is provided with an anti-rust layer 8, and the anti-rust layer 8 is formed by soaking in a passivation solution; through the arrangement of the antirust layer 8, because the passivation solution is composed of various efficient complexing agents, corrosion inhibitors and the like, the antirust agent is essentially different from common antirust oil or a sealing agent, after the surface of the stainless iron is soaked and contacted with the passivation solution, a micro chemical reaction is generated on the surface of the stainless iron, the original metal surface with active chemical property is converted into a metal surface with inert chemical property, the purpose that the metal surface with inactive chemical property is difficult to generate chemical reaction with external substances is achieved, the long-term antirust effect is achieved, and the problem that the stud 1 is difficult to transfer due to rusting on the surface can be avoided.
It should be noted that the utility model relates to a protective equipment screw for orthopedic nursing, including 1 stud, 2 screw tops, 3 twisted rings, 4 springs, 5 washers, 6 cavities, 7 frosted layers, 8 antirust layers, the components are all universal standard components or components known by technicians in this field, the structure and principle of the protective equipment screw are all known by technicians in this field through technical manuals or through conventional test methods, when a protective equipment screw for orthopedic nursing is used, firstly, the stud 1 is aligned to the threaded hole on the protective equipment, then the twisted ring 3 is rotated to drive the stud 1 to rotate so that the stud 1 gradually turns over into the threaded hole on the protective equipment, the rotation is stopped until the washer 5 contacts with the threaded hole and the screw top 2 respectively, thereby the installation work of the screw is completed, the washer 5 is squeezed under the effect of the spring 4, the anti-loosening effect of the stud 1 is improved, and the setting of the frosted layer 7 is utilized, the frictional force between the washer 5 and the protector and the screw top 2 is increased, and the stud 1 is further prevented from loosening.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above, it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, but that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
