Description
Technical field
The utility model relates to a kind of connection parts of automobile, and in particular to one kind manually adjusts connecting shaft.
Background technique
Connecting shaft is equipped with after automobile in arrester, connecting shaft includes screw rod and outer-hexagonal head, between screw rod and outer-hexagonal head
Equipped with sealing cylinder, the outer round surface for sealing cylinder is equipped with right-left seal slot, and right-left seal slot is fixedly installed, can only in seal groove
It is packed into elastic seal ring, and elastic seal ring is generally rubber material, so the elevated-temperature seal effect of connecting shaft is poor and easily old
Change, service life is shorter.
Summary of the invention
In view of the deficiency of background technique, the technical problem to be solved by the utility model is to provide can fill in a kind of seal groove
Enter nonrubber sealing ring, improves elevated-temperature seal effect, manually adjust connecting shaft come what is prolonged the service life.
For this purpose, the utility model adopts the following technical scheme that realize:
Connecting shaft, including screw rod and outer-hexagonal head are manually adjusted, sealing cylinder, sealing are equipped between screw rod and outer-hexagonal head
The outer round surface of cylinder is equipped with right-left seal slot, it is characterised in that: the slot bottom of right-left seal slot is set on slot bottom cylinder, slot bottom circle
The outer circle movable sleeve of column is equipped with ring body, and the outside diameter of ring body is equal to the outside diameter of sealing cylinder, and the left side of ring body is a left side
The right side trough rim of seal groove, the right side of ring body are the left side trough rim of right seal groove；Slot bottom cylinder is fixedly linked with outer-hexagonal head
And be structure as a whole, the left end face of slot bottom cylinder is equipped with connector, and connector is equipped with external screw thread, and the right end face of screw rod is equipped with
Threaded hole, threaded hole have and the matched internal screw thread of external screw thread.
Above-mentioned technical proposal manually adjusts connecting shaft, is slidingly connected ring equipped with slot bottom cylinder and in the outer circle of slot bottom cylinder
Body, the outer circle of slot bottom cylinder forms the right-left seal slot of sealing cylinder in the left and right sides of ring body, when installing sealing ring, can first by
Right sealing ring is packed into slot bottom outer circle, then covers upper ring body, and left sealing ring is then packed into slot bottom outer circle again, completes in above-mentioned movement
Afterwards, slot bottom cylinder is fixedly linked in such a way that screw thread is screwed on by connector and screw rod, then just constitutes prior art shape
Connecting shaft；The connecting shaft of above structure, since sealing ring is not required to elasticity and struts be placed into right-left seal slot, so right-left seal
It can be packed into nonrubber sealing ring in slot, the elevated-temperature seal effect of connecting shaft is improved, to prolong the service life.
Preferably, the right half of screw rod has outer cone shape, the stub end direction sealing cylinder of Outer Taper.
