Abstract
The utility model discloses a kind of rotation seal joints, including fitting sleeve, fitting sleeve is equipped with axial pass-through holes, it is characterized by: being coaxially provided with fixed jacket outside fitting sleeve, fitting sleeve rotation is set to the inner hole of fixed jacket, fixed jacket is connected with fixed bracket, the lower end surface of fitting sleeve is equipped with mounting flange, it is inserted into fixed sleeving from top to bottom in the axial pass-through holes, airtight and watertight padding chamber is reserved between the outer circle of fixed sleeving and the hole wall of axial pass-through holes, the intracavitary merging airtight and watertight padding of airtight and watertight padding, airtight and watertight padding is compressed by gland, fixed sleeving is connected with fixed jacket.The utility model has the advantages that compact-sized, solves the big technical problem of traditional rotation seal joint axial dimension, more preferably meets the needs of engineering construction.
Description
Technical field
The utility model relates to a kind of constructional engineering machineries, and in particular to be a kind of engineering driller rotatory sealing
Connector.
Background technique
In engineering construction, this engineering equipment of drilling machine, the rotation seal joint on drilling machine are largely used, fitting sleeve turns
Dynamic supporting portion and sealing position are axial arrangings, so the rotation seal joint of the drilling machine of the prior art, general axial direction ruler
Very little meeting is larger, cannot meet the needs of engineering construction very well in certain occasions.
Summary of the invention
In view of currently known technology there are the problem of, the technical problems to be solved in the utility model is to be to provide a kind of tool
Have the advantages that compact-sized, solves the big technical problem of traditional product axial dimension, more preferably meet the rotation of engineering construction needs
Seal nipple.
In order to solve the above technical problems, the utility model adopts the following technical scheme that complete:
A kind of rotation seal joint, including fitting sleeve, fitting sleeve are equipped with axial pass-through holes, it is characterised in that: outside fitting sleeve
It is coaxially provided with fixed jacket, fitting sleeve rotation is set to the inner hole of fixed jacket, and fixed jacket is connected with fixed bracket, fitting sleeve
Lower end surface be equipped with mounting flange, be inserted into fixed sleeving in the axial pass-through holes from top to bottom, the outer circle of fixed sleeving with
Airtight and watertight padding chamber is reserved between the hole wall of axial pass-through holes, the intracavitary merging airtight and watertight padding of airtight and watertight padding, airtight and watertight padding is by filler pressure
Lid is compressed, and fixed sleeving is connected with fixed jacket.
Rotating support position and the sealing position of fitting sleeve are improved to coaxial by the rotation seal joint of above-mentioned technical proposal
It lays, so the axial dimension of final rotation seal joint product will be smaller, therefore has the advantages that compact-sized, solution
The big technical problem of traditional rotation seal joint product axial dimension, more preferably meets the needs of engineering construction.
Preferably, the hole wall of the axial pass-through holes is additionally provided with several seal grooves in the lower position of airtight and watertight padding chamber,
Seal groove is built into square type or O-ring seal.Above-mentioned design can more preferably guarantee the seal request of fitting sleeve.
Preferably, the fitting sleeve is by metal (upper rotation above and below the inner hole of fixed jacket, fixed jacket
End face is equipped with upper lower cover and carries out compression positioning to metal (upper.
Preferably, the airtight and watertight padding is the V-seal ring of stacked on top setting.Utilize the heap up and down of V-seal ring
The folded packing seal formed, has the characteristics that sealing effect is good.
Detailed description of the invention
The utility model has following attached drawing:
Fig. 1 is the structural schematic diagram of the utility model.
