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
External three station driving devices driving, the drive link of transmission device are penetrated outside gas-filling cabinet inside 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 insulation performance of product can be reduced after the leakage of SF6 gases, triggers 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
It asks, the term of validity of sealing must reach 30 years.
Utility model content
Purpose of utility model：In view of the above-mentioned problems, the purpose of this utility model is to provide a kind of gas-filling cabinet drive link with close
Seal apparatus mounted on the joint of drive link and gas-filling cabinet, ensures that the gas in gas-filling cabinet can not occur for a long time in joint
Leakage.
Technical solution：A kind of gas-filling cabinet drive link sealing device including internal gassiness gas-filling cabinet and is worn
Drive link on the gas tank plate of gas-filling cabinet, further includes seal disc, bearing, sealing ring one, sealing ring two, and the seal disc is arranged
It is installed in the drive link and the gas tank plate, the bearing is mounted between the seal disc and the drive link, described close
The sealing ring one is equipped between the composition surface of closing disk and the gas tank plate, the seal disc circumferentially rotates face with the drive link
Between be equipped 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
A sealing ring causes sealing effect more preferably.
Further, the present apparatus further includes clamp spring, circumferentially spaced on the inner wall of the seal disc to offer two annular grooves,
The clamp spring is fastened in the annular groove, and the bearing and the sealing ring two are located between two clamp springs, and clamp spring is to axis
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 outer 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.
Advantageous effect：Compared with prior art, the utility model has the advantages that：Ensureing the situation of drive link normal work
Under, it ensure that the air-tightness inside gas-filling cabinet, effectively prevent the leakage of the gas-filling cabinet internal gas caused by drive rod rotation
Situation, long-term sealing function can be played, sealing effect is good；The present apparatus is easy for installation, simple and compact for structure, occupied space
It is small, strong applicability.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
Illustrate the utility model rather than limitation the scope of the utility model, after the utility model has been read, art technology
Personnel fall within the application scope as defined in the appended claims to the modification of the various equivalent forms of the utility model.
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 further includes seal disc 3, bearing 4, sealing ring 1, sealing ring 26, clamp spring
7。
Seal disc 3 is sheathed on drive link 2 and is 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 mounted 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 outer diameter of drive link 2, and the inner wall drive link 2 of sealing ring 26 is made closely to paste
It closes, 26 outer wall of sealing ring is fitted closely with seal disc 3, the fitting of adjacent 26 end face of sealing ring, and the opposite fitting of sealing ring 26 is set
It puts, further strengthens sealing effect, the sealing ring 26 near bearing 4 is bonded with 4 end face of bearing, and bearing 4 is close to gas-filling cabinet 1
