Abstract
The utility model relates to an oil injection device of a capacitor, particularly to a simple sealing mechanism of an oil injection head of a capacitor, comprising an oil injection head and a sealing gasket, the simple sealing mechanism is characterized in that: the lower part of the oil injection head is an oil injection pipe, the upper end of the oil injection pipe is communicated with an oil injection guide hole on the oil injection head, an indented ladder-shaped sealing gasket groove is arranged at the bottom part of the oil injection pipe, the sealing gasket consists of an inserting part with a shape corresponding to the sealing gasket groove and a compression-connecting part which is connected at the lower end of the inserting part, and the inserting part and the compression-connecting part are provided with an oil hole runs through a pipe hole of the oil injection pipe in an integrated way. The simple sealing mechanism mainly solves the technical problem that a sealing ring is easy to leave at the oil injection hole of a power capacitor when the existing oil injection head of the capacitor is used, and the sealing mechanism is simple in structure,convenient to assemble, and is integrated with the oil injection head and has good sealing effect.
Description
Technical field
The utility model relates to a kind of capacitor oiling device, a particularly a kind of easy capacitor oiling sealing mechanism.
Background technology
As everyone knows, capacitor manufacturer is when carrying out the impregnating agent injection to the oil filler point on the capacitor, and the oiling device of use comprises the injection device main body and is arranged on the oiling head of body front end and the sealing ring outside the oiling head.A kind of novel electric power capacitor oiling device is just disclosed like Chinese utility model patent specification (Granted publication CN201667293U); Comprise the rubber ring that plays sealing function in this device; The lower part of this rubber ring is connected in the pouring orifice of power capacitor, and the lower end of the oil fuel tube of oiling head is passed rubber ring and inserted in the power capacitor.
Visible by said structure, the lower part of sealing circle is to be fastened on the pouring orifice of power capacitor but not to be connected fully on the oiling head.In case when the oiling head need carry out the oiling operation to the another power capacitor, after the oiling head was extracted, rubber ring often was retained in the pouring orifice of power capacitor easily, operating personnel need be through installing after manual the extracting again.Troublesome poeration so not only, and damage sealing ring easily.
The utility model content
The purpose of the utility model is to provide an a kind of easy capacitor oiling sealing mechanism; It mainly solves when having the use of capacitor oiling head now; Sealing ring often is retained in the technical problem of the pouring orifice of power capacitor easily; It is simple in structure, easy for installation, is integral with the oiling capitiform, and good sealing effect.
For realizing above-mentioned purpose, the technical scheme of the utility model is following.
An a kind of easy capacitor oiling sealing mechanism, it comprises oiling head and sealing gasket, it is characterized in that: the bottom of described oiling head is an oil fuel tube, this oil fuel tube upper end is communicated with oiling guide hole on the oiling head; Described oil fuel tube bottom has the stair-stepping gasket slot of indent; Described sealing gasket is made up of with the pressure contact portion that is connected the lower end, Plug Division the cartridge part of profile corresponding to gasket slot, and this cartridge part and pressure contact portion have the oilhole that connects with oil fuel tube pore one.
A described easy capacitor oiling sealing mechanism, it is characterized in that: described oilhole aperture is consistent with oil fuel tube pore aperture.
A described easy capacitor oiling sealing mechanism, it is characterized in that: the external diameter of described pressure contact portion is consistent with the external diameter of oil fuel tube.
By technique scheme, the utlity model has following technique effect.
1, the utility model structure can guarantee that finish does not overflow, and has good sealing effectiveness in the oiling operation.
2, it is very simple that the sealing gasket of the utility model is installed to the operation of oiling head, only need rabbet fitting operation and get final product.
3, the sealing gasket of the utility model is difficult for breaking away from the oiling head, and therefore the wearing and tearing probability is less in the operation, and useful life is longer.

Embodiment
See also Fig. 1-6, it is the structural representation of a kind of easy capacitor oiling sealing mechanism of the utility model.As shown in the figure: it comprises oiling 1 and sealing gasket 2, it is characterized in that: the bottom 5 of described oiling head is oil fuel tube, and the oiling guide hole 6 in this oil fuel tube upper end and the oiling 1 is communicated with; Described oil fuel tube bottom has the stair-stepping gasket slot 7 of indent; Described sealing gasket 2 is made up of with the pressure contact portion 9 that is connected 8 lower ends, Plug Division the cartridge part 8 of profile corresponding to gasket slot 7, and this cartridge part 8 has the oilhole 10 that connects with oil fuel tube pore one with pressure contact portion 9.
As a kind of preferred structure, described oilhole 10 apertures are consistent with oil fuel tube pore aperture.
As a kind of preferred structure, the external diameter of described pressure contact portion 9 is consistent with the external diameter of oil fuel tube.
During use, the Plug Division 8 of sealing gasket 2 is inserted into the oil fuel tube bottom has in the stair-stepping gasket slot 7 of indent, and then the oiling head that will install sealing gasket 2 is attached to capacitor oil filler point place; And need guarantee that oilhole 10 aims at oil filler point; So just can implement the oiling operation, in the operation, sealing effectiveness is more satisfactory; Avoid overflowing of finish, ensured operating environment.
The preferred embodiment that the above is merely the utility model is not the practical range that is used for limiting the utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be the technological category of the utility model.
