Abstract
The utility model relates to a screw waterproof oil filler cap which is composed of a casing 1, a platform 2, a connection tube 3, a pinhole 4, an oil sticky pad 5, a sponge 6, a top cover 7 and waterproof edges 8. As the oil filler cap adopts the structure of engine oil permeation, the oil filler cap has the characteristics of convenient use, simple structure, automatic permeation and no need of screw rust cleaning, can be used for various occasions, and is especially suitable for protecting bolt assemblies on steel rails on railroads.
Description
The utility model belongs to the bolt assembly protective articles, and specifically it is a kind of screw waterproof oiling cap.
Many engineering assemblies are in the field throughout the year, its environment very severe, and the bolt assembly corrosion on it is serious.In order to address this problem, application number is to have introduced a kind of Stainless cap nut in China's utility application prospectus of 91205426.3, it is to be provided with the top cover that is connected as a single entity with it on the height and the top of the corresponding positive hexagonal prism of bolt protruded length, be provided with the internal thread that is meshed with bolt in this cylinder center hole, be provided with the internal diameter that is connected as a single entity with it skirt cap greater than the top internal diameter in the bottom of cylinder, this Stainless cap nut is used for the bolt on the railway cement sleeper, has waterproof effect.But this Stainless cap nut does not have automatic oil-injecting function, thus rustless property a little less than.
The purpose of this utility model provides a kind of screw waterproof oiling cap, to overcome the deficiencies in the prior art.
The purpose of this utility model can reach by following structures.The utility model has a tubular shape shell, one platform that is connected as a single entity with it is arranged in the shell medium position, one connecting tube that protrudes upward that is connected as a single entity with it is arranged at the center of platform, internal thread is arranged in connecting tube, the aperture that communicates is up and down arranged on platform, a top cover that matches with it is arranged on the shell top.So in use, the utility model connects with quilt protection screw by its connecting tube and makes nut be positioned at shell, opens top cover, inwardly inject machine oil, cover top cover then, machine oil makes screw remain organic oil and exists by the slowly infiltration downwards of the aperture on the platform.
For machine oil is directly permeated in the screw connection place, the aperture on the utility model platform can be positioned at the junction point of platform and connecting tube.Like this, machine oil just can directly permeate on lead screw, improves the utilization ratio of machine oil.
For easy to use, the utility model can have sponge or sponge shape packing on platform.So in use or just machine oil can be injected during product export, machine oil is included in sponge or the packing and can not flows out, just can directly use in the open air and must not re-inject machine oil.
In order to adjust the permeation rate of machine oil, the utility model can have an oil to be stained with pad between platform and sponge or sponge shape packing.Like this, can be stained with the permeation rate that thickness that pad or oil is stained with pad is adjusted machine oil, make it adapt to different occasions and use by different oil.
In order to strengthen sealability and to strengthen waterproof effect, the utility model can have a diameter that is connected as a single entity with shell to strengthen gradually in the shell bottom and shell wall becomes broad anti-waterside gradually.So in use, when carrying tight the utility model, the utility model is contacted closely with workpiece, reach waterproof effect.
The utility model has been owing to adopted the machine oil infiltration structure, make the utlity model has infiltration easy to use, simple in structure, automatic, must not be to the characteristics of screw rust cleaning, thereby reached the purpose of this utility model.
Accompanying drawing has provided an embodiment of the present utility model.Following structure accompanying drawing further specifies concrete structure of the present utility model.
Accompanying drawing 1 is a cross-sectional view of the present utility model.Among the figure, 1 is shell, a platform 2 is arranged in the middle, at platform 2 centers one connecting tube that protrudes upward 3 is arranged, the aperture 4 that communicates is up and down arranged on platform 2, on platform 2, have an oil to be stained with pad 5, being stained with pad at oil has sponge 6 on 5, on shell 1 top one top cover 7 is arranged, and an anti-waterside 8 is arranged in shell 1 bottom.
The utility model can be used for multiple occasion, is specially adapted to the protection of bolt assembly on the railway track.
