Description
Technical field
The present invention relates to a kind of electrical equipment, more particularly, to a kind of gas-filling cabinet drive link sealing device.
Background technology
Three-station inside gas-filling cabinet needs to carry out folding by transmission device, and transmission device is by being arranged at gas-filling cabinet
Outside three station drive devices driving, the drive link of transmission device are penetrated inside gas-filling cabinet outside gas-filling cabinet, pass through a system
Biographies move the folding that step completes three-station, due to being filled with the SF6 gases more than a standard atmospheric pressure in gas tank,
On the one hand SF6 gases pollute the environment, on the other hand, the insulating properties of product can be reduced after the leakage of SF6 gases, trigger accident,
Therefore, in the joint of drive link and gas-filling cabinet, it is necessary to carry out sealing, it is ensured that SF6 gases do not leak, will according to using
Ask, the term of validity of sealing must reach 30 years.
The content of the invention
Goal of the invention：In view of the above-mentioned problems, it is an object of the invention to provide a kind of gas-filling cabinet drive link sealing device, peace
Mounted in the joint of drive link and gas-filling cabinet, ensure that the gas in gas-filling cabinet can not leak for a long time in joint.
Technical scheme：A kind of gas-filling cabinet drive link sealing device, including internal gassiness gas-filling cabinet and wear
Drive link on the gas tank plate of gas-filling cabinet, in addition to seal disc, bearing, sealing ring one, sealing ring two, the seal disc are arranged
Installed in the drive link and the gas tank plate, the bearing is arranged between the seal disc and the drive link, described close
The sealing ring one is provided between the composition surface of closing disk and the gas tank plate, the seal disc circumferentially rotates face with the drive link
Between be provided with the sealing ring two.
Sealing ring one prevents the gas in gas-filling cabinet from being leaked from the installation place of the present apparatus, and sealing ring two is prevented in gas-filling cabinet
Gas leaks between seal disc and drive link, and prevents gas drive link from being leaked when rotating.
Further, the sealing ring two is at least provided with two, and end face is bonded between the adjacent sealing ring two, sets more
Individual sealing ring causes sealing effectiveness more preferably.
Further, the present apparatus also includes jump ring, circumferentially spaced on the inwall of the seal disc to offer two annular grooves,
The jump ring is fastened in the annular groove, and the bearing and the sealing ring two are between two jump rings, and jump ring is to axle
Hold has position-limiting action with sealing ring two.
Further, the bearing is bonded with the sealing ring biend, and the bearing is on the outside of the gas-filling cabinet, institute
Sealing ring two is stated on the inside of the gas-filling cabinet.
Optimal, the internal diameter of the sealing ring two is less than the external diameter of the drive link so that sealing ring two can be firm
It is fastened between seal disc and drive link.
Optimal, the sealing ring two is EPDM rubber circle.
Optimal, the bearing is zanjon ball bearing.
Beneficial effect：Compared with prior art, it is an advantage of the invention that：In the case where ensureing drive link normal work,
The air-tightness inside gas-filling cabinet is ensure that, effectively prevents the feelings of the leakage of gas-filling cabinet internal gas caused by drive rod rotation
Condition, long-term sealing function, good sealing effect can be played；The present apparatus is easy for installation, simple and compact for structure, occupies little space,
Strong applicability.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate
The present invention rather than limitation the scope of the present invention, after the present invention has been read, those skilled in the art are each to the present invention's
The modification of the kind equivalent form of value falls within the application appended claims limited range.
A kind of gas-filling cabinet drive link sealing device, as shown in figure 1, including internal gassiness gas-filling cabinet 1 and wearing
Drive link 2 on the gas tank plate 11 of gas-filling cabinet 1, in addition to seal disc 3, bearing 4, sealing ring 1, sealing ring 26, jump ring
7。
Seal disc 3 is sheathed on drive link 2 and installed with gas tank plate 11, is set between the composition surface of seal disc 3 and gas tank plate 11
There is sealing ring 1, it is outer that sealing ring 1 can prevent that the gas in gas-filling cabinet 1 from leaking into from the joint of seal disc 3 and gas tank plate 11
Portion, bearing 4 are arranged between seal disc 3 and drive link 2, and bearing 4 is zanjon ball bearing, and model can be 6005Z etc., sealing
26 are enclosed at least provided with two, the material of sealing ring 26 is EPDM rubber, and seal disc 3 and drive link 2 are set between circumferentially rotating face
There is sealing ring 26, the internal diameter of sealing ring 26 is less than the external diameter of drive link 2, the inwall drive link 2 of sealing ring 26 is closely pasted
Close, the outer wall of sealing ring 26 is brought into close contact with seal disc 3, the fitting of the adjacent end face of sealing ring 26, and the relative fitting of sealing ring 26 is set
Put, further strengthen sealing effectiveness, the sealing ring 26 near bearing 4 is bonded with the end face of bearing 4, and bearing 4 is close to gas-filling cabinet 1
Outside, sealing ring 26 is circumferentially spaced on the inner side of gas-filling cabinet 1, the inwall of seal disc 3 to offer two annular grooves 31,
Jump ring 7 is fastened in the annular groove 31, and two jump rings 7 are bonded with bearing 4, the end face of sealing ring 26 respectively, and two jump rings 7 are by axle
