This copper sheathing is provided with the sealing washer, and this sealing washer cross section is triangle-shaped, and the internal diameter of sealing washer slightly is less than the internal diameter of main part in addition, when piston rod back-and-forth movement left side, the sealing washer will block oil inside the copper sheathing, can not make the copper sheathing in have and spill, keeps always leading to the lubrication in the cover, and reducing wear improves the life of copper sheathing, and the cross section of sealing washer is triangle-shaped simultaneously, is elastic material moreover, guarantees that the piston rod can normally pass in and out, does not influence the use.
Description
Technical Field
The utility model belongs to the technical field of laboratory bacterial culture, specifically be a copper sheathing.
Background
The copper bush, also called copper bush, is divided into various types, including machine copper roller, copper bearing, etc. The composite material is used for various light, large and heavy machines and is an important component on the machine. The product has traditional tin bronze bearing function to electrolytic copper is equipped with multiple trace metal element as the raw materials, through high temperature sintering, forms through atmospheric pressure centrifugal casting processing, and the copper sheathing is through the contact of terminal surface with the moving part, not only need play the effect of supporting, need reduce the wearing and tearing of moving part simultaneously, therefore the copper sheathing terminal surface need add lubricating grease, because terminal surface and moving part frequent contact, lubricating grease is easy to be lost, can influence life.
Disclosure of Invention
To the above-mentioned problem that prior art exists, the utility model aims to solve the technical problem that a copper sheathing is provided to solve present copper sheathing lubricating oil and spill easily, problem that life is not long.
In order to solve the technical problem, the utility model discloses a technical scheme be:
the utility model provides a copper sheathing, includes main part, oil groove, sealing washer and dust ring, evenly be provided with the oil groove in the main part, the both ends of main part all are provided with 2 grooves, and one is square groove, and one is the dovetail groove, and the dovetail groove is embedded to have the sealing washer, and square inslot is embedded to have the dust ring, the dust ring is located the outermost extreme of main part.
Furthermore, the outermost circle of oil groove is adjacent with the dovetail groove, and does not communicate with each other.
Further, the square groove is adjacent to the trapezoidal groove, the square groove is arranged on the outer side, and the trapezoidal groove is arranged on the inner side.
Furthermore, the cross section of sealing washer is triangle-shaped, and the sealing washer is inlayed in the dovetail groove, and the outside and the dovetail groove bottom edge of sealing washer cooperate.
Further, the inner diameter of the sealing ring is smaller than that of the main body.
Further, the sealing ring is made of an elastic material.
Has the advantages that: compared with the prior art, the method has the following advantages:
this copper sheathing is provided with the sealing washer, and this sealing washer cross section is triangle-shaped, and the internal diameter of sealing washer slightly is less than the internal diameter of main part in addition, when piston rod back-and-forth movement left side, the sealing washer will block oil inside the copper sheathing, can not make the copper sheathing in have and spill, keeps always leading to the lubrication in the cover, and reducing wear improves the life of copper sheathing, and the cross section of sealing washer is triangle-shaped simultaneously, is elastic material moreover, guarantees that the piston rod can normally pass in and out, does not influence the use.
Drawings
Fig. 1 is a schematic structural view of a copper bush.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the copper sheathing of this application, including main part 1, oil groove 2, sealing washer 3 and dust ring 4, evenly be provided with oil groove 2 in the main part 1, inject lubricating oil in the oil groove 2, reduce the wearing and tearing of copper sheathing, the most outside circle of oil groove 2 sets up the inboard at the dovetail groove, when the piston rod was taken out from the copper sheathing, lubricating oil can be blockked by sealing washer 3, the lubricating oil that is blockked flows into in the oil groove 2, cyclic utilization, can not flow, effectual improvement life, main part 1's both ends all are provided with 2 grooves, one is square groove, one is the dovetail groove, and the trapezoidal inslot is inlayed and is had sealing washer 3, square inslot is inlayed and is inlayed dust ring 4, dust ring 4 is located the most outside of main part 1, equation circle's effect is inside just in order to prevent that external dust from getting into the copper sheathing, the friction is improved, copper sheathing.
The outermost circle of oil groove 2 is adjacent with the dovetail groove, and does not communicate with each other, and when the piston rod was taken out in following the copper sheathing, lubricating oil can be blockked by sealing washer 3, and in the lubricating oil inflow oil groove 2 that is blockked, cyclic utilization can not flow out, effectual improvement life.
The square groove is adjacent to the trapezoidal groove, the square groove is arranged on the outer side, the trapezoidal groove is arranged on the inner side, the dustproof ring is arranged on the outermost side, the sealing ring 3 is arranged on the inner side, the copper sleeve is enabled to be oil-tight, ash can be blocked, and the service life of the copper sleeve is greatly prolonged.
The cross section of sealing washer 3 is triangle-shaped, and sealing washer 3 inlays in the dovetail groove, and the outside and the dovetail groove bottom limit of sealing washer 3 cooperate, and sealing washer 3 cooperatees with the dovetail groove, can pin the lubricating oil in the copper sheathing, keeps lubricated.
The inner diameter of the sealing ring 3 is smaller than that of the main body 1, when the piston rod moves left and back, the sealing ring can block oil inside the copper sleeve, leakage in the copper sleeve cannot happen, lubrication in the through sleeve is kept all the time, abrasion is reduced, and the service life of the copper sleeve is prolonged.
The sealing ring 3 is made of elastic material, so that the normal movement of the copper sleeve is not influenced, and only the leakage of lubricating oil is prevented.
The utility model provides a thinking and implementation method of copper sheathing, it is many to use the way specifically, above only the utility model discloses an optimal implementation mode should point out, to the ordinary technical personnel of this technical field, does not deviate from the utility model discloses under the prerequisite of principle, can also make a plurality of improvements, these improvements should also be regarded as the utility model discloses a protection scope.
