Abstract
The utility model discloses a door rotary shaft convenient for people to add lubricating oil and relates to the field of lubrication. In order to reduce mutual friction between a central shaft of the rotary shaft and a sleeve, the utility model designs the door rotary shaft convenient for people to add lubricating oil. According to the technical scheme, the door rotary shaft convenient for people to add lubricating oil is characterized in that a door is fixed on a door frame by the rotary shaft; the rotary shaft is composed of the central shaft and the sleeve; the sleeve is composed of an upper part and a lower part, wherein one part is fixed on the door frame, and the other part is fixed on the door; the sleeve part which is fixed on the door rotates around the central shaft. The door rotary shaft convenient for people to add lubricating oil is further characterized in that a sleeve notch is formed in the top of the upper part of the sleeve, wherein the top of the central shaft is arranged below the sleeve notch; a vertical central shaft groove is formed in the central shaft. The door rotary shaft has the beneficial effects that lubricating oil drops which are dropped in from the sleeve notch can penetrate to the central shaft of the rotary shaft, and part of the lubricating oil drops flow down along the central shaft groove; by virtue of the rotation, the lubricating oil is uniformly coated on the sleeve inner surface and the central shaft surface of the rotary shaft, so that friction is reduced, and the service life of the rotary shaft is prolonged.
Description
Technical field
The utility model relates to lubricated field, particularly the lubricated aspect of door rotating shaft.
Background technology
The rotating shaft sealing of family's door, along with passage of time, become drier between the central axis of rotating shaft and sleeve, easily produce larger friction, and produce ear-piercing grating, and this grating has influence on neighbours' life and rest, and friction causes central axis and sleeve mutually to wear and tear, easily damage door, affect the firm performance of door.
Summary of the invention
For the central axis of minimizing rotating shaft and the phase mutual friction between sleeve, extend the application life of rotating shaft, a kind of door rotating shaft of being convenient to apply oil of the utility model design.
The utility model realizes that the technical scheme that goal of the invention adopts is: a kind of door rotating shaft of being convenient to apply oil, door is fixed on doorframe by rotating shaft, rotating shaft is comprised of central axis and sleeve, central axis is positioned at sleeve inner, sleeve is by upper, lower two parts form, wherein a part is fixed on doorframe, another part is fixed on door, the sleeve part be fixed on door rotates around central axis, it is characterized in that: the top of the upper part of sleeve, a sleeve breach is arranged, the top of central axis is positioned at the below of sleeve breach, central axis has a vertical central axis groove.
The sleeve breach is circular hole, and diameter is 5-8mm.Perhaps, the sleeve breach is square, and the length of side is 5-8mm.The degree of depth of central axis groove is that 1mm, width are 1-2mm.The replacement scheme that has identical function with the central axis groove is, sleeve is outwards outstanding, and the height of projection is that 1mm, width are 1-2mm.
The beneficial effects of the utility model are: the lubrication oil oil droplet splashed into from the sleeve breach can be penetrated into the central axis of rotating shaft, part is dirty along the central axis groove, by rotation, make lubrication oil evenly be applied to sleeve interior surface and the central axis surface of rotating shaft, thereby reduce the friction between shaft sleeve and central axis, extend its application life.
The accompanying drawing explanation
Fig. 1 is a kind of door schematic diagram of being convenient to apply oil.Fig. 2 is the rotating shaft schematic diagram.
Wherein, 1, doorframe, 2, door, 3, rotating shaft, 4, the central axis groove, 5, sleeve breach.
The specific embodiment
Door 2 is fixed on doorframe 1 by rotating shaft 3, rotating shaft 3 is comprised of central axis and sleeve, central axis is positioned at sleeve inner, sleeve is by upper, lower two parts form, wherein a part is fixed on doorframe 1, another part is fixed on door 2, the sleeve part be fixed on door rotates around central axis, the upper part top of sleeve, a sleeve breach 5 is arranged, the top of central axis is positioned at the below of sleeve breach 5, central axis has a vertical central axis groove 4, the degree of depth of central axis groove 4 is 1mm, width is 1-2mm, this central axis groove 4 is beneficial to lubrication oil and moves down, by door, rotate, be applied to fast central axis surface and the sleeve interior surface of rotating shaft, the replacement scheme that has identical function with central axis groove 4 is, sleeve is outwards outstanding, the height of projection is 1mm, width is 1-2mm.
