Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides the following technical solutions: the utility model provides a protection oil blanket, includes

casing

1, 1 inner wall of casing is equipped with and has elastic supporting part 2, be equipped with a plurality of protection lips 3 on the supporting part 2, protection lips 3 have elasticity, protection lips 3's tip has the arc arch 4 of evagination, protection lips 3 are located the both sides of arc arch 4 and are equipped with contact site 5.

The utility model discloses an in the embodiment, use supporting part 2 to the incurve between work piece 11 and shell, thereby press protective lip 3 between supporting part 2 and work piece 11, make protective lip 3 and work piece 11 contact, when dustproof or leak protection, a plurality of protective lip 3 can play multiple protective action, and then play better dustproof or leak protection effect, meanwhile, can store lubricating oil in the arc arch 4 on the protective lip 3, can play dustproof or leak protection simultaneously, can play dustproof or the dustproof effect of air contact face again, lubricating oil in the arc arch 4 can be better dustproof.

Further, the number of the support parts 2 is at least one, when the number of the support parts 2 is plural, the lower ends of the support parts 2 are in splayed contact with the outside of the workpiece 11, and the inclination directions of the protection lips 3 and the support parts 2 are the same; the outward bending of the splayed outside of the supporting part 2, the protective lip 3 can play better reverse separation to external impurities, and play a better protective role.

Further, the clearance between the contact portion 5 of the end of each of the protection lips 3 and the workpiece 11 thereof is smaller than the clearance between the inner side contact portion 5 thereof and the workpiece 11; so can form thinner lubricating oil film at the tip of protective lip 3, when playing the lubrication, inseparabler contact can effectual separation external impurity, and have great clearance between 4 inboard contact site 5 of arc arch and work piece 11, can be when 4 positions of arc arch lack lubricating oil, make lubricating oil supplement in 4 to arc arch, arc arch 4 plays the effect of deposit lubricating oil, prevent to form dry friction between protective lip 3 and the work piece 11, and damage the oil blanket, thereby make the oil blanket have longer life.

Furthermore, a framework 6 positioned at the contact part 5 of the protective lip 3 is arranged in the protective lip; the device is used for maintaining the gap between the contact part 5 and the workpiece 11, simultaneously ensuring that the contact part 5 and the workpiece 11 have proper contact force, and preventing the protective lip 3 from being too close to the workpiece 11 or insufficient in contact force, thereby more effectively forming a good lubricating oil film.

Preferably, the contact part 5 at the end of the protective lip 3 is in surface contact with the workpiece 11, so that the end of the protective lip 3 has better dustproof effect and better prevents lubricating oil from leaking; the contact part 5 at the inner side of the protective lip 3 is in line contact; so that the lubrication can break through the contact part 5 on the inner side of the arc-shaped bulge 4 and timely supplement the lubricating oil to the inside of the arc-shaped bulge 4.

Furthermore, a plurality of reinforcing ribs 7 which are uniformly distributed are arranged on the outer surface of the protective lip 3; the shape of the protective lip 3 is better maintained, and the protective lip 3 is prevented from deforming, so that lubricating oil is leaked from the contact part 5 or external dust enters.

Further, an oil storage part 8 is arranged in the supporting part 2, and a leakage hole 9 for releasing lubricating oil to the protective lip 3 is arranged on the inner side of the supporting part 2; be used for when 2 positions of supporting part are crooked, pour into lubricating oil into between a plurality of protection lips 3 through small opening 9, be formed with oily sealing again between a plurality of protection lips 3, can cooperate protection lip 3 to form multichannel protection, play maximum protective effect.

Further, the air side of the shell 1 is provided with a dustproof tile 10; used for blocking most dust and impurities outside and reducing the protection pressure of the protection lip 3.
