Please disclosed high-tension vacuum switch equipment divide-shut brake drive link, including epoxy glass fabric stick, front end inserts and rear end inserts, ring
Oxygen glass cloth stick both ends are threaded hole, and front end inserts is screwed into the threaded hole at epoxy glass fabric stick both ends and rear end is embedding
Part.In order to which the more fastening ensured between epoxy glass fabric stick and front end inserts and rear end inserts couples and reduces epoxy glass fabric
Air gap between stick and front end inserts and rear end inserts is coated with insulating cement on the surface of the front end inserts and rear end inserts, is
Insulating cement is made to fill up air gap, air is excluded, is machined with gas vent on the front end inserts and rear end inserts, ensure that epoxy
Coupling between glass cloth stick and front end inserts and rear end inserts more fastens, and reduce epoxy glass fabric stick and front end inserts and
Air gap between the inserts of rear end.In addition, front end inserts and the coupling spindle thread connection of operation insulator, and with anaerobism glue sticking,
The rear end inserts of insulator and disc spring energy storing device thread connection are operated, and equally uses anaerobism glue sticking.
But front end inserts is with coupling spindle when coupling, and since coupling spindle is solid construction, and has after gluing certain close
Seal effect, when screwing into threaded hole bottom gas compression generate pressure it is larger, therefore will appear external screw thread can not be complete
Wheel enters the problem of threaded hole bottom.To avoid the above problem, as shown in Figure 1, can be set on coupling spindle 91 in the prior art
Axially extending bore 92, so that gas is discharged.But above-mentioned connecting rod is when being used for hydraulic system, during use after the curing of extra glue
The colloid of formation is easily detached from operation is vibrated, and then enters hydraulic system, and the cleannes that can cause hydraulic system are exceeded, and
It may scratch or weigh sealing element wounded and cause oil leak, leakproofness is caused to fail, seriously affects the normal operation of system.
Invention content
The object of the present invention is to provide a kind of thread connection gluing connecting rods, come off and can influence to solve colloid in the prior art
The problem of cleannes and sealing performance of hydraulic system；Meanwhile the present invention also provides a kind of hydraulic operatings using the connecting rod
Mechanism.
The technical solution adopted by the present invention is：Thread connection gluing connecting rod, including being equipped with the first rod piece of threaded hole and setting
There is externally threaded second rod piece, first rod piece and at least one of the second rod piece are equipped with gas held chamber, the gas
Bottom hole of the accommodating chamber only with the threaded hole communicates.
The gas held chamber is formed by the axial blind hole being arranged on the first rod piece or the second rod piece.
The axial blind hole is arranged on the shaft core position of the second rod piece.
The bottom hole of the threaded hole is equipped with taper apex point, and the opening of the axial blind hole and the tapered bur spivot are to right
It should.
Hydraulic actuating mechanism, the connecting rod coupled including energy storage device and with energy storage device, the connecting rod include being equipped with screw thread
First rod piece in hole and equipped with externally threaded second rod piece, first rod piece and at least one of the second rod piece are equipped with gas
Accommodating chamber, bottom hole of the gas held chamber only with the threaded hole communicate.
The gas held chamber is formed by the axial blind hole being arranged on the first rod piece or the second rod piece.
The axial blind hole is arranged on the shaft core position of the second rod piece.
The bottom hole of the threaded hole is equipped with taper apex point, and the opening of the axial blind hole and the tapered bur spivot are to right
It should.
The present invention is equipped with gas held chamber using above-mentioned technical proposal, the first rod piece and at least one of the second rod piece,
Bottom hole of the gas held chamber only with the threaded hole communicates, when the second rod piece screws in the first rod piece, the gas in threaded hole
It can be compressed in gas held chamber, so as to reduce the gas pressure of threaded hole bottom, compared with prior art, can avoid
There is the problem of external screw thread can not be completely screwed into threaded hole bottom, rapid operation, operating efficiency is high, simultaneously as gas held
Chamber is only communicated with the bottom hole of threaded hole, even if the colloid formed after glue curing comes off, can also be blocked in the enclosed space, no
Hydraulic system can be entered or contacted with sealing element, can effectively avoid influence of the colloid to cleannes and sealing performance.
Description of the drawings
Fig. 1 is the structure diagram of connecting rod in the prior art；
Fig. 2 is the structure diagram of one embodiment of thread connection gluing connecting rod of the present invention.
Each reference numeral is corresponding entitled in figure：The first rod pieces of 10-, 11- threaded holes, 12- taper apex points, 20- second

The gas held chamber of body.The bottom hole center of threaded hole 11 is equipped with taper apex point 12, axial corresponding with axial blind hole 22.
When assembling connecting rod, then the gluing on the external screw thread 21 of the second rod piece 20 screws in the external screw thread 21 for being coated with glue
In threaded hole 11 on first connecting rod, with the increase and decrease of screw-in depth, compressed in threaded hole 11 by the gas that glue seals up
And a part enters in the axial blind hole 22 on second connecting rod, axial blind hole 22 provides enough spaces for gas compression, avoids
Pressure is excessive in threaded hole 11 causes external screw thread 21 that can not be completely screwed into, rapid operation, and operating efficiency is high, meanwhile, extra glue
The colloid formed after 30 curings can be blocked in the enclosure space formed by axial blind hole 22 and threaded hole 11, will not enter liquid
Pressure system is contacted with sealing element, can effectively avoid influence of the colloid to cleannes and sealing performance, is conducive to improve product
Quality, reduce after cost.
In the above-described embodiments, gas held chamber is formed by the axial blind hole 22 being arranged on the second rod piece 20, at this
In the other embodiment of invention, gas held chamber can also replace with other forms, such as in the second rod piece 20 towards the first bar
Groove on the end face of part 10 is set, axial blind hole is set on 11 bottom wall of threaded hole for another example, forms gas held chamber.In addition,
Connecting rod in above-described embodiment can be used in other hydraulic systems.
One embodiment of hydraulic actuating mechanism includes energy storage device and the connecting rod coupled with energy storage device in the present invention, even
The thread connection gluing connecting rod of bar, that is, above-mentioned, details are not described herein again.
