Problems solved by technology

Similarly, when the nut is in use, the lubricating oil naturally flows into the joint between the screw rod and the nut of the bolt, without any power-assisted action, which may cause the lubricating oil to flow out of the oil outlet hole, and the oil outlet and lubrication efficiency are slow

Abstract

The invention discloses an automatic oil outlet nut. The automatic oil outlet nut comprises a nut body, wherein a threaded hole is formed inside the nut body; an annular oil storage tank is arranged inside the nut body and is filled with lubricating oil; at least two oil outlet holes are axially formed in the nut body; each oil outlet hole comprises an oil inlet flow channel and two labyrinth-shaped oil outlet flow channels; each oil inlet flow channel is communicated with the oil storage tank; each oil outlet flow channel is communicated with the threaded hole; a piston is arranged at an opening of the oil storage tank; at least two cylinders are annularly arrayed in the nut body; the end part of a telescopic rod of each cylinder is connected with the piston; a switch which controls the cylinders is arranged on the outer surface of the nut body. The automatic oil outlet nut is easy to operate, convenient to use and high in oil outlet efficiency and lubricating efficiency; the lubricating oil cannot be leaked when being stored in the oil storage tank, so that the lubricating effect of the lubricating oil during use is guaranteed.

Description

technical field [0001] The invention relates to a nut, in particular to an automatic oil outlet nut, which belongs to the technical field of mechanical fasteners. Background technique [0002] A nut is a nut, a part that is screwed together with a bolt or a screw for fastening, and is widely used in mechanical equipment. However, in the current enterprises, due to the lack of regular maintenance of mechanical equipment, and under the influence of environmental humidity and other factors, the bolts will rust and die, resulting in the bolts not being removed, causing unnecessary troubles, affecting work efficiency, and delaying normal operation of mechanical equipment. [0003] For example, the Chinese invention patent "A Kind of Nut", the application number is 201120460564.5, discloses a kind of nut. When the nut and the bolt matched with it are rusted in a humid environment or corroded by harmful gas, the plug I is pulled out, and the round The lubricating oil in the shape...
