Abstract
The utility model relates to a plunger rod and belongs to the field of steelmaking machinery. The plunger rod is connected through a spherical head and capable of continuous oiling. The plunger rod is composed of a plunger rod cap, a plunger rod body and a plunger rod sleeve. The spherical head is arranged at one end of the plunger rod body. A clamping cap is arranged at the end portion of the plunger rod cap. A groove is formed in the clamping cap. A left hemispherical groove corresponding to the left side of the spherical head is formed at the other end of the clamping cap. The inner portion of the plunger rod sleeve is composed of a clamping cap cavity, a sleeve cap cavity and a rod cavity. The cap cavity corresponds to the clamping cap. Inner threads of the sleeve cap cavity are meshed with outer threads of the plunger rod cap. A right hemispherical groove corresponding to the right side of the spherical head is formed in a cavity of the plunger rod sleeve. The plunger rod is simple in structure, low in cost, convenient to assemble and install, stable in spherical head connection, capable of preventing the spherical head from falling down, good in centering performance and capable of guaranteeing that lubricating grease is supplied to a lubricated portion constantly, prolonging the service life of parts and reducing repair cost.
Description
Technical field
The utility model belongs to the steel-making mechanical field.
Background technique
Existing assembling form is that circlip type connects, because of 0.8 millimeter of jump ring diameter, be mixed with foreign material in jump ring one experience wear or the grease in the use, plunger rod and plunger pole socket are thrown off cause the oil pump cisco unity malfunction, and most faults are all plunger rod and break away from due to the plunger pole socket, and the plunger rod assembling need be set up special tool and non-dismountable.
Summary of the invention
The purpose of this utility model provides a kind of employing bulb and connects the plunger rod that can refuel continuously.
The utility model is made up of plunger pole cap, plunger rod and plunger rod cover, and an end of plunger rod is ballhead; There is the card cap plunger pole cap end, on the card cap groove is arranged, and the other end of card cap has the left hemisphere groove corresponding with the ballhead left side; Plunger rod cover inside is made up of clip cap chamber, cap bag chamber and bar chamber, cap chamber corresponding card cap, and the outside thread engagement of the internal thread in cap bag chamber and plunger pole cap has the right hemisphere groove corresponding with the ballhead right side in the chamber of plunger rod cover.
The utility model is simple in structure, and cost is low, assembles easy for installationly, and bulb connects and firmly not come off, and is good to neutrality, guarantees that lubricating grease continuously sends into the lubricant housings.Prolong parts working life; Reduce maintenance expenses.
