Oilhole connect described serving chamber and described go out rope race, on described charging hole connect have topping-up portion, described topping-up portion is built with lubrication
Oil, described lubricating oil can enter described charging hole, then arrive described serving chamber and institute via described charging hole from described topping-up portion
State out rope race.Lubricating oil can be added to enclosure interior easily, without dismounting housing by said structure.
As preferably, described topping-up portion includes the oil storing tube being provided with shoe cream room, and promotes described lubricating oil from described
The push rod gone out in shoe cream room, described push rod can be along described oil storing tube axially-movable, to change described shoe cream room volume.
This structure is similar to the structure of syringe, can topping-up easily and fast.
Further, described push rod includes piston portion, threaded portion and Handheld Division, corresponding described oil storing tube being provided with
Screwed hole, described piston portion fits tightly with described oil storing tube inwall, and described threaded portion coordinates with described screwed hole, it is achieved institute
Stating push rod can be along described oil storing tube axially-movable while described oil storing tube rotates, and described handgrip part is in described storage
Outside oil pipe.Arranging of helicitic texture can be avoided touching push rod by mistake and carrying out topping-up, and this structure can only pass through rotating push-rod part
Just can carry out topping-up.
As improvement, described oil storing tube also setting up and is provided with topping-up rifle, described topping-up rifle closely pastes with described charging hole
Close.Arranging of topping-up rifle can make lubricating oil arrive appointment position accurately.
Further, described charging hole be arranged on described in go out directly over rope race, described topping-up portion and described go out rope race be in
One direction.Make lubricating oil can accurately enter out rope race, improve lubricant effect.
Compared with prior art, the utility model has the advantage of: can be easily by lubrication by arranging of topping-up portion
Oil adds enclosure interior to, without dismounting housing.Arrive the purpose facilitating oil addition.
