Automatic oil outlet bolt

Abstract

The invention discloses an automatic oil outlet bolt which comprises a bolt body. A bolt head and a screw are connected with each other to form the bolt body, and an oil storage groove is formed inside the screw; the oil storage groove is filled with lubricating oil; oil outlet holes which are communicated with the oil storage groove are axially formed in the screw; the oil outlet holes comprise oil inlet flow channels and oil outlet flow channels; the oil inlet flow channels are communicated with the oil outlet flow channels; each oil outlet hole comprises the two corresponding labyrinth oil outlet flow channels; a piston is arranged at an opening of the oil storage groove; a cylinder is arranged in the bolt head; an end of a telescopic rod of the cylinder is connected with the piston; a switch for controlling the cylinder is arranged on the outer surface of the bolt head. The automatic oil outlet bolt has the advantages that the automatic oil outlet bolt is simple in operation, convenient to use and high in oil outlet and lubrication efficiency; each oil outlet hole comprises the two corresponding labyrinth oil outlet flow channels, accordingly, the lubricating oil can be prevented from leaking when stored in the oil storage groove, and lubrication effects of the lubricating oil can be guaranteed when the automatic oil outlet bolt is used.

Description

Technical field [0001] The invention relates to a bolt, particularly an automatic oil outlet bolt, and belongs to the technical field of mechanical fasteners. Background technique [0002] A bolt is a type of fastener consisting of a bolt head and a screw (cylinder with external thread), which is used to fasten and connect two mechanical equipment parts with through holes. This type of connection is called bolt connection, which is a detachable connection. However, in current enterprises, due to the lack of regular maintenance of machinery and equipment, and the influence of factors such as humidity in the environment, the bolts will be rusted, resulting in the bolts being unable to be removed, causing unnecessary trouble, affecting work efficiency, and delaying The normal operation of mechanical equipment. [0003] For example, the Chinese invention patent "A New Type of Bolt", the application number is 201120460551.8, discloses a new type of bolt. When the bolt is rusted, use t...

AI Technical Summary

Problems solved by technology

After the bolt is rusted, it is necessary to use an oiler to inject lubricating oil into the oiling tank, which is cumbersome and slow in oiling efficiency; the specifications of the oiler must match the hole size of the oiling tank, if the size does not match, it will cause oil to leak out There is no lubricating oil in the hole or the lubricating oil splashes out, so that each specification of the bolt needs to be equipped with an oiler or an oiler connector, which is expensive to use
