Embodiment 1

[0022] like figure 1 As shown, a novel non-loosening screw of the present invention is mainly composed of a variable diameter screw rod (4), a main nut (5), an auxiliary nut (6), an anti-loosening device (7), and a double anti-loosening sleeve (8) Composed of five components. The so-called variable-diameter screw is because there is a variable-diameter part (9) on the screw, which is called the main body section (1) from the head of the screw to the variable-diameter part, and the part where the auxiliary nut is installed at the tail of the screw is called the secondary nut section (2) main body The screw rod diameter of section, length and thread specification are the standard index of screw, and main nut (5) is installed on the thread of reducing screw rod (4). The diameter of auxiliary nut section (2) dwindles 1-10 millimeter than the diameter of main body section (1), and auxiliary nut (6) is installed on the thread of auxiliary nut section (2). The anti-loosening device...

Embodiment 2

[0025] In a project, a new type of non-loosening screw is used, and a cover-type anti-loosening device is selected.

[0026] The installation process is as follows:

[0027] The first step is to pass the prepared reduced-diameter screw (4) through the screw hole that needs to be fastened, and then install the gasket (10) from the end of the screw; the second step is to install the main nut (5) to the screw On the thread of the main body section (1), after the final screwing, the inspection is qualified; the third step is to insert the main nut (6) into the sleeve (18) of the cover type anti-loosening device, so that the auxiliary nut (6) and the sleeve The cover-type anti-loosening device is combined into one, and they are installed together on the thread of the auxiliary nut section (2); the fourth step is to install the double anti-loosening sleeve (8) from the tail of the screw to the cover-type anti-loosening device ( 7), push the double anti-loosening sleeve (8) inward, ...

Abstract

The invention discloses a novel non-loose screw. The novel non-loose screw is mainly formed by combining a variable-diameter screw rod, a main nut, an auxiliary nut, an anti-loosening device and a double-joint anti-loose sleeve. The novel non-loose screw is simple in structure and ideal in anti-loose effect. The novel non-loose screw can be applied to special equipment with high-rotation speed, high-speed movement, strong vibration and high-low temperature change and the like, and can realize high-reliability and long-service-life use requirements without self-loosening and falling.

Description

technical field [0001] The invention relates to a special screw, especially a special screw which cannot be loosened. That is, under normal use conditions, it will not be damaged by high-speed rotation, strong vibration, high temperature (within the range of its metal material to maintain mechanical strength), low temperature (within the range of its metal material to maintain mechanical strength) and indirect damage. Loosen loose screws by themselves. Background technique [0002] Screws are standard parts commonly used in industrial equipment and products, and are extremely versatile. Screws are simple in structure, easy to use, and play a role in connection and fastening in various structures. With the development of science and technology, many new industrial equipment, heavy equipment, and special equipment used in special environments must be used under complex conditions such as high speed, high speed movement, strong vibration, and high and low temperature changes....
