Abstract
The utility model relates to a chain wheel case machine oil tank filler sleeve device, including chain wheel case and tank filler sleeve part, its characterized in that: the tank filler sleeve parts are the integral type structure of base, connection position and top component, base, connection position and top connect gradually, the base is circularly, and center department opens there is the through -hole, and the connection position is cylindricly, and the top is outside convex semi -circle or the semiellipse appears, the internal diameter of connecting position department equals the diameter of through -hole, and the external diameter of connecting position department is lighter than base diameter, chain wheel case is last be provided with with tank filler sleeve part assorted round hole, tank filler sleeve part and round hole sealing connection. The utility model discloses simple structure, convenient to use, good, the low in manufacturing cost of sealing performance accord with the market trend that small -size farm machinery is inexpensive.
Description
Technical field
This utility model relates to a kind of chain-wheel box machine oil oiling hole device, belongs to the technical field of chain-wheel box.
Background technology
The machine oil tank filler sleeve of the chain-wheel box of prior art is the cap structure of structure relative complex, relative complex, switch trouble, and it is inconvenient to refuel.
The utility model that publication number is CN2672428 discloses a kind of gear cover oiling hole device, including buckle closure, the neck that refuels, the outer wall of the side of buckle closure and oiling neck porch is hinged together, the opposite side of buckle closure is locked on the outer wall of oiling neck by retaining mechanism, buckle closure and refuel neck top opening between be provided with sealing member, described sealing member is installed in the gap between rubber gasket and rubber gasket and the buckle closure on buckle closure inwall axially mounted spring and constitutes by sliding axially.Add, with oiling neck porch, the sealing member being made up of spring and rubber gasket so that when buckle closure is locked, rubber gasket is pressed on oiling neck entrance, has stopped the generation of leakage of oil situation at buckle closure.But it still has cover-buckling structure, and population structure is complex, be not suitable on small agricultural machinery chain-wheel box oiling hole device.
Utility model content
This utility model aims to provide the chain-wheel box machine oil oiling hole device of a kind of simple in construction, easy to use, good seal performance.
The technical solution of the utility model is: a kind of chain-wheel box machine oil oiling hole device, including chain-wheel box and tank filler sleeve parts, it is characterised in that: being provided with through hole on described chain-wheel box, tank filler sleeve parts are arranged at through hole and form sealing with through hole.Simple in construction, during oiling, can lunge tank filler sleeve assembly either directly through injection needle, inwardly inject machine oil.
As preferably, described tank filler sleeve parts are made up of the base being sequentially connected with, connecting portion and top.
As preferably, described base is rounded, and center has through hole, and cylindrically, top is outwardly semicircle or half elliptic to connecting portion.Not only save material usage, be also convenient for inserting and extracting of tank filler sleeve parts.
As preferably, the internal diameter at described connecting portion place is equal to the diameter of through hole, and the external diameter at connecting portion place is less than base diameter.Easily facilitate extracting of tank filler sleeve parts.
As preferably, described tank filler sleeve parts are the integral structure that base, connecting portion and top form.Make overall structure more firm.
As preferably, described tank filler sleeve parts are quality of rubber materials.Extract after needle pierces, pin hole can on automatic-sealed, it is to avoid the leakage of machine oil.
The tank filler sleeve similar button structure of parts global shape of the present utility model, simple in construction is small and exquisite, and employing is elastomeric material, as long as machine oil being passed through during oiling the needle pierces top of syringe, oil is injected in chain-wheel box, after adding, directly extracts syringe needle, on the pouring orifice meeting automatic-sealed lid at top, easy to lubricate, simple in construction, and be conveniently replaceable, manufacturing cost is also low, and the market that suitable small agricultural machinery is inexpensive tends to.

Fig. 2 is the structural representation of tank filler sleeve parts in Fig. 1；
Fig. 3 is the profile of Fig. 2.
In figure: 1-chain-wheel box, 11-circular hole, 2-tank filler sleeve parts, 21-base, 211-through hole, 22-connecting portion, 23 tops.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model embodiment is described in detail.
Referring to Fig. 1-Fig. 3, chain-wheel box machine oil oiling hole device in the present embodiment includes chain-wheel box 1 and tank filler sleeve parts 2, chain-wheel box 1 is provided with the circular hole 11 matched with tank filler sleeve parts 2, tank filler sleeve parts 2 are made up of the base 21 being sequentially connected with, connecting portion 22 and top 23, and are integral type structure.Base 21 is rounded, center has through hole 211, and cylindrically, top 23 is in outwardly semicircle or half elliptic for connecting portion 22, the internal diameter D1 at described connecting portion 22 place is equal to the diameter D3 of through hole 211, and the outer diameter D 2 at connecting portion 22 place is less than base diameter D4.
Tank filler sleeve parts 2 are quality of rubber materials, it is also possible to for other soft elastic material.
Tank filler sleeve parts need not be taken out during oiling, either directly through the top 23 of the needle pierces tank filler sleeve parts of syringe, in chain-wheel box 1, inject machine oil.Syringe needle is extracted rear pin hole and can automatically be closed, and when tank filler sleeve parts sealing effectiveness declines, can change at any time, very easy to use.
By above description, those skilled in the art can implement.
This utility model has been made more detailed description by above example; but these describe is not to restriction of the present utility model, protection domain of the present utility model includes those apparent conversion or replacement and remodeling to those skilled in the art.
