[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.
[0022] Please refer to Figures 1-4 , in the present utility model, a non-loosening screw for mechanical connection includes a screw end 1. The bottom surface of the screw end 1 is fixedly connected to a rod body 2. The bottom end of the rod body 2 is fixedly connected to a screw head 3. A thread groove 4 is formed on the outer surface of the rod body 2. An elastic locking strip 5 is fixedly connected inside the thread groove 4. A thread locking ring 6 is threadedly connected to the outer circle of the rod body 2. An external hexagon connector 7 is fixedly connected to the upper surface of the thread locking ring 6. An elastic gasket 8 is fixedly connected to the bottom surface of the thread locking ring 6. The elastic gasket 8 is made of rubber. The elastic locking strip 5 can make the thread groove 4 in close contact with the inside of the mechanical equipment when the rod body 2 is connected to the mechanical equipment. The thread locking ring 6 and the external hexagon connector 7 can achieve a good locking effect when the rod body 2 is connected to the mechanical equipment.
[0023] The upper surface of the screw end 1 is provided with an internal hexagonal tightening groove 9 with a diameter of one centimeter. The outer surfaces of the screw end 1 and the rod body 2 are both sprayed with an electroplated coating. The ratio of the screw end 1 to the rod body 2 is 1:6. An adjusting gasket 10 is provided outside the rod body 2, and the adjusting gasket 10 is made of stainless steel. The internal hexagonal tightening groove 9 facilitates the staff to twist the screw end 1 with a hexagonal wrench. The electroplated coatings sprayed on the outer surface of the screw end 1 and the outer surface of the rod body 2 can increase the corrosion resistance of the screw end 1 and the rod body 2, thereby increasing the service life of the screw end 1 and the rod body 2. The adjusting gasket 10 can prevent the threaded locking ring 6 from contacting the mechanical equipment when the threaded locking ring 6 locks the rod body 2.
[0024] Above the screw end 1 is provided with a screw model identification plate 11. The bottom surface of the screw model identification plate 11 is connected to the upper surface of the screw end 1. Two fixing blocks 12 are fixedly connected to the upper surface of the screw end 1, and through holes 13 are opened inside both of the two fixing blocks 12. The screw model identification plate 11 facilitates the staff to check the specific model of this product. The fixing blocks 12 and the through holes 13 enable the staff to twist the screw end 1 with other tools when the hexagonal wrench is lost.
[0025] The working principle of the present utility model is:
[0026] When using this product, the staff first puts the adjusting gasket 10 on the outside of the rod body 2. Then, the staff inserts the screw head 3 into the mechanical equipment and inserts the hexagonal wrench into the internal hexagonal tightening groove 9, and then twists the screw end 1. Thus, the rotation of the screw end 1 drives the rod body 2 to rotate inside the mechanical equipment, so that the rod body 2 slowly enters the mechanical equipment. When the rod body 2 completely enters the mechanical equipment, the elastic locking strip 5 outside the threaded groove 4 will contact the inside of the mechanical equipment. At this time, the staff uses other tools to twist the external hexagonal connecting piece 7, and drives the threaded locking ring 6 to slowly rotate downward until the threaded locking ring 6 contacts the mechanical equipment. The above is the entire operation process of this product.
[0027] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
