Abstract
The utility model discloses a hole for adding lubricating oil to a door spindle and relates to the field of lubrication, particularly to the lubrication of door spindles. By means of the hole, friction between a central shaft and a sleeve of the spindle is reduced and the service life of the spindle is prolonged. According to the technical scheme, a door, a door frame and the spindle are included, the door and the door frame are connected through the spindle, and the spindle is composed of the central shaft and the sleeve. The hole is characterized in that a gap exists between the top of the inner side of the sleeve and the central shaft, an oiling hole is formed in the sleeve outside the gap, and oil drops dropped from the oiling hole can penetrate the central shaft of the spindle. The hole is characterized in that the oil drops dropped from the oiling hole can penetrate the central shaft of the spindle, and oil can be spread on the sleeve and the central shaft of the spindle through rotation, so that friction between the sleeve and the central shaft of the spindle can be reduced, and the service life of the spindle can be prolonged; a shielding piece of the oiling hole can prevent dust from entering the central spindle; and adding of the lubricating oil to the spindle is facilitated by the aid of the oiling hole.
Description
Technical field
The utility model relates to lubricated field, particularly the lubricated aspect of door rotating shaft.
Background technology
The door rotating shaft sealing of family, rotating shaft is made up of central axis and the outside sleeve of inside, and is relatively drier between the central axis of rotating shaft and the sleeve, be easy to generate bigger friction, cause wearing and tearing mutually between central axis and the sleeve, cause door to damage easily, have influence on indoor article and personnel's safety.
Summary of the invention
For the central axis of minimizing rotating shaft and the phase mutual friction between the sleeve, prolong the application life of rotating shaft, the utility model designs the hole that lubrication oil is added in a kind of door rotating shaft.
The utility model realizes that the technical scheme that goal of the invention adopts is: the hole of lubrication oil is added in a kind of door rotating shaft, comprise door, doorframe and rotating shaft, door is connected by rotating shaft with doorframe, rotating shaft is made up of central axis and sleeve, it is characterized in that: top and the central axis of the sleeve inner of rotating shaft have the space, sleeve outside the space has a tank filler sleeve, and the oil droplet that splashes into from tank filler sleeve can be penetrated into the central axis of rotating shaft.
Tank filler sleeve is hidden by a shielding plate, and shielding plate is hinged to the top of cartridges sides.
The beneficial effects of the utility model are: the oil droplet that splashes into from tank filler sleeve can be penetrated into the central axis of rotating shaft, by rotation, makes oil be applied to sleeve and the central axis of rotating shaft, thereby reduces the friction between shaft sleeve and the central axis, prolongs its application life; Tank filler sleeve is hidden by a shielding plate, avoids dust to enter central rotating shaft; Tank filler sleeve is conducive to add lubrication oil to rotating shaft smoothly.

Wherein, 1, doorframe, 2, door, 3, rotating shaft, 4, tank filler sleeve, 5, shielding plate.
The specific embodiment
The hole of lubrication oil is added in a kind of door rotating shaft, with the common door identical point is: door 2 is connected by rotating shaft 3 with doorframe 1, and rotating shaft is made up of inside center axle and outer sleeve.The places different with the common door rotating shaft are: the top of the sleeve inner of rotating shaft 3 and central axis have certain space, sleeve outside the space has a tank filler sleeve 4, the oil droplet that splashes into from tank filler sleeve 4 can be penetrated into the central axis of rotating shaft, by rotation, make oil be applied to sleeve and the central axis of rotating shaft, thereby reduce the friction between shaft sleeve and the central axis, prolong its application life.
For avoiding dust to enter central rotating shaft, tank filler sleeve 4 is hidden by a shielding plate 5, and shielding plate 5 is hinged to the top of cartridges sides.
