Embodiment Construction
[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.
[0027] In the description of the present invention, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it may be a fixed connection, a detachable connection, or an integral connection. Ground connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in specific situations.

The invention relates to the technical field of fasteners, in particular to a safety fastener with a separated anti-loosening mechanism, which comprises a bolt head and a threaded rod. The safety fastener with the separating type anti-loosening mechanism is composed of an upper threaded connecting pipe with a bolt head at the top and a lower threaded assembling pipe which is movably assembled through a middle elastic locking linkage mechanism. The lower threaded assembly pipe and the upper threaded connection pipe can be separated after the fastener is installed, so that the lower threaded assembly pipe is not affected by the outside, and the anti-loosening performance is greatly improved; once the upper threaded connecting pipe is loosened outwards, only the pulling force among the other lower threaded assembling pipes is increased, so that the anti-loosening property of the whole fastener is further improved, and the safety is greatly improved; and the lower thread assembly pipe can be independently controlled by lifting the outer hexagonal pressing block upwards, so that the controllable modes of the bolt are more diversified, and the application range is wider.
Description
technical field [0001] The invention relates to the technical field of fasteners, in particular to a safety fastener with a separate anti-releasing mechanism. Background technique [0002] Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc., in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, etc. , chemical industry, instruments and supplies, etc., all kinds of fasteners can be seen, which are the most widely used mechanical basic parts. [0003] The bolt is the most common type of fastener, as long as it is equipped with a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with an external thread) that needs to be matched with a nut to fasten and con...
