Description
Technical field
The utility model relates to a kind of nut, and particularly a kind of automatic oil outlet nut, belongs to machanical fastener technical field.
Background technique
Nut is exactly nut, is used for the part played the role of fastening with bolt or screw rod together with being screwed in, and is widely used in machinery.But in present enterprise, owing to lacking the maintaining regularly to machinery, simultaneously under the impact of the factors such as humid environment, bolt can be caused to become rusty dead, cause bolt to unload to get off, cause unnecessary trouble, affect working efficiency, delay the normal operation of machinery.
As Chinese utility model patent " a kind of nut ", application number is 201120460564.5, disclose a kind of nut, the bolt be mated when this nut in a humid environment or harmful gas corrode to issue and get rusty after death, corkage I, lubricant oil in circular oil storage tank just can ooze screw rod and the nut connecting part of profit bolt, and nut can be unloaded fast.In use, lubricant oil is screw rod and the nut connecting part that nature flows into bolt to this nut, without any power-assisted action, oil outlet may be caused not go out lubricant oil, fuel-displaced slow with lubricating efficiency.
And for example Chinese utility model patent " a kind of hexagon nut ", application number is 201220146248.5, disclose a kind of hexagon nut, the bolt be mated when this nut in a humid environment or harmful gas corrode to issue and get rusty after death, the thawing of the solid lubrication be in oil groove oil can be in a liquid state by heater, ooze screw rod and the nut connecting part of profit bolt, nut can be unloaded fast.Equally, in use, lubricant oil is screw rod and the nut connecting part that nature flows into bolt to this nut, without any power-assisted action, oil outlet may be caused not go out lubricant oil, fuel-displaced slow with lubricating efficiency.
Model utility content
The utility model object provides a kind of lubricant oil pressurized to be extruded the automatic oil outlet nut oozed out to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of automatic oil outlet oil return nut, comprises nut body, have tapped hole in described nut body, and described nut body inside is provided with annular oil storage tank; Full lubricant oil is established in described oil storage tank; Described nut body axially has at least two oil outlets; Described oil outlet comprises oil-feed runner and fuel-displaced runner; Described oil-feed runner communicates with oil storage tank; Described fuel-displaced runner communicates with tapped hole; Described fuel-displaced runner is provided with two, and in labyrinth-like; The opening of described oil storage tank is provided with piston; In described nut body, annular array has at least two cylinders; The flexible rod end of described cylinder is connected with piston; The outer surface of described nut body is provided with the switch of control cylinder.
Preferably, described piston jacket has seal ring.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Automatic oil outlet nut of the present utility model, establishes full lubricant oil in oil storage tank, the bolt be mated when this nut rust occurs after death, piston press oil storage tank inner space, lubricant oil will ooze out from oil outlet, the screw rod of lubrication bolt and nut connecting part, and nut can be removed; Simple to operate, easy to use, fuel-displaced high with lubricating efficiency; Because fuel-displaced runner is provided with two, and in labyrinth-like, can not leak when making lubricant oil be stored in oil storage tank, ensure that the lubrication effect of lubricant oil during use.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of automatic oil outlet nut of the present utility model;
Accompanying drawing 2 is the using state schematic diagram of automatic oil outlet nut of the present utility model;
Wherein: 1, nut body; 2, tapped hole; 3, oil storage tank; 4, oil-feed runner; 5, fuel-displaced runner; 6, piston; 7, cylinder; 8, switch; 9, seal ring; 10, bolt.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Described in the utility model a kind of automatic oil outlet nut as shown in Figure 1, comprises nut body 1, has tapped hole 2 in described nut body 1, and described nut body 1 inside is provided with annular oil storage tank 3; Full lubricant oil is established in described oil storage tank 3; Described nut body 1 axially has at least two oil outlets; Described oil outlet comprises oil-feed runner 4 and fuel-displaced runner 5; Described oil-feed runner 4 communicates with oil storage tank 3; Described fuel-displaced runner 5 communicates with tapped hole 2; Described fuel-displaced runner 5 is provided with two, and in labyrinth-like; The opening of described oil storage tank 3 is provided with piston 6; In described nut body 1, annular array has at least two cylinders 7; The flexible rod end of described cylinder 7 is connected with piston 6; The outer surface of described nut body 1 is provided with the switch 8 of control cylinder 7; In order to increase sealing between piston 6 and oil storage tank 3, described piston 6 overcoat has seal ring 10.
Described in the utility model a kind of automatic oil outlet nut as shown in Figure 2, bolt 10 that nut is mated occur rust dead twist motionless after, press switch 8, cylinder 7 starts, and the flexible rod of cylinder 7 stretches out, piston 6 is driven to extrude oil storage tank 3 inner space, lubricant oil will ooze out through oil-feed runner 4 and fuel-displaced runner 5, the screw rod of lubrication bolt 10 and the connecting part of nut, and nut so just can be made to be turned, because lubricant oil is oozed out by piston 6 extruding, fuel-displaced high with lubricating efficiency; Due to the screw rod of bolt 10 and the connecting part of nut lubricated, nut can be backed out fast, reduces unnecessary dead time, add the working efficiency of machinery; Because fuel-displaced runner is provided with two, and in labyrinth-like, can not leak when making lubricant oil be stored in oil storage tank, ensure that the lubrication effect of lubricant oil during use; Automatic oil outlet nut of the present utility model, simple to operate, easy to use, as long as Push switch just can realize fuel-displaced and oil return, the mode of mechanization reduces the labor intensity of workman, improves working efficiency.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technological scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
