The periphery wall of the butt end stating the first pipeline 1 and second pipe 2 sets the first pipeline chimb 11 and second pipe chimb 21 respectively.
When pipeline connects installation, first described first pipeline 1 is inserted in one end of described inner connection tube 3, then by described inner connection tube 3
The other end inserts described second pipe 2, and the mouth of pipe of the first pipeline 1 and second pipe 2 is connected to described inner connection tube 3 respectively
The both sides of isolation convex tendon 31, it is achieved dock and described inner connection tube 3 can be made to be positioned at the first pipeline owing to arranging isolation convex tendon 31
1 and second pipe 2 the mouth of pipe at, the migration of inner connection tube 3 will not be caused because of manifold pressure change.Corresponding described isolation is convex
Muscle 31 is provided with convex tendon detent, corresponding first pipeline chimb 11 and second pipe chimb 21 at the inwall of described hoop sleeve 4
Inwall at described hoop sleeve 4 is provided with the first detent and the second detent.In the present embodiment, convex tendon detent,
First detent and the merging of the second detent are processed as same detent 41.When pipeline connects installation, by hoop sleeve 4
It is installed at the docking port of the first pipeline 1 and the first pipeline 2, accordingly, isolation convex tendon the 31, first pipeline chimb 11 and the
Two pipeline chimbs 21 all embed in the detent 41 of hoop sleeve 4, then by the mutual clamping of clamping piece 42 of hoop sleeve 4
On, it is achieved thereby that the axial restraint of the first pipeline 1 and second pipe 2 is connected, it is also convenient for dismounting.Pipeline need to keeped in repair
Time, conveniently pull down assembling pipe joint, the most repeatable recycling of this attachment means, so that cost-saved, it is to avoid waste.
Embodiment two
As it is shown on figure 3, the difference of the present embodiment metallic conduit attachment means and embodiment one is described hoop sleeve in the form of a ring, by 1
Clamping piece 42 forms, and clamping piece 42 snaps connection for non-dismountable.This non-dismountable company is used in the installation of yard piping
Connect mode hoop sleeve 4 locked pipeline docking port, thus can pre-anti-theft pipe.
Embodiment three
As shown in Figure 4 and Figure 5, with the difference of embodiment one, the present embodiment metallic conduit attachment means is that hoop sleeve 4 is cyclic spring
Sheet, sets installation fracture 43 at described hoop sleeve 4.When pipeline connects and installs, because hoop sleeve 4 has bullet for cyclic spring sheet
Property, therefore only need to be opened from installation incision position by hoop sleeve 4 with instruments such as pincers, then hoop sleeve 4 is installed on the first pipeline 1 He
At the docking port of second pipe 2, instrument of taking away restores to the original state by hoop sleeve 4, makes hoop sleeve 4 be clamped on the first pipeline and second
At the docking port of pipeline.This simple in construction, it is easy to install.
Embodiment four
As shown in Figure 6, a kind of metallic conduit attachment means, including the first pipeline 1, second pipe 2, inner connection tube 3, hoop sleeve
4.Wherein, hoop sleeve 4 in the form of a ring, is made up of two sections of clamping pieces, by detachably snapping connection between two clamping pieces.First
The connecting portion of pipeline 1 is the first reducing 10, and the internal diameter of described first reducing 10 is more than the internal diameter of described first pipeline 1, institute
The connecting portion stating second pipe 2 is the second reducing 20, and the internal diameter of described second reducing 20 is interior more than described second pipe 2
Footpath, the external diameter of described inner connection tube 3 is less than internal diameter and the internal diameter of the second reducing 20 of described first reducing 10, in described
The two ends of connecting tube 3 are inserted described first reducing the 10, second reducing 20 respectively and are made described first pipeline 1 and described second pipe 2
Road seals docking, and described first reducing 10 is axially positioned with described second reducing 20 and is connected by hoop sleeve 4.Because of the first reducing
The caliber of 10 is more than the first pipeline 1, forms a step in the junction of the two, same, the second reducing 20 and the second pipe
The junction in road 2 also forms a step, and so, inner connection tube 3 inserts in the first reducing 10 and the second reducing 20, interior company
The screens respectively of the two ends of adapter 3, at above-mentioned step, can make described inner connection tube 3 be positioned at the first reducing 10 and the second reducing
At 20, the migration of inner connection tube 3 will not be caused because of manifold pressure change, make structure more stable.At described first reducing 10
The first pipeline chimb 11, second pipe chimb 21 is set respectively with the periphery wall of the butt end of the second reducing 20.Corresponding first pipeline
Chimb 11 and second pipe chimb 21, the inwall at described hoop sleeve 4 is provided with the first detent and the second detent.?
In the present embodiment, the first detent and the merging of the second detent are processed as same detent 41.At inner connection tube 3
It is respectively equipped with o-ring groove 31 on outer wall, if sealing ring 6, sealing ring 6 is arranged in described o-ring groove 32.Will
It is interior to realize the location of sealing ring 6 that sealing ring 6 is arranged on o-ring groove 32, it is to avoid it walks because installation friction causes.Borrow
Described sealing ring 6 is helped to realize being tightly connected of described inner connection tube 3 and described first reducing 10 and described second reducing 20.Pipe
When road connects installation, hoop sleeve 4 is installed at the docking port of the first pipeline 1 and the first pipeline 2, accordingly, the first pipeline
Chimb 11 and second pipe chimb 21 all embed in the detent 41 of hoop sleeve 4, then by the clamping piece phase of hoop sleeve 4
Card connects mutually, it is achieved thereby that connect the axial restraint of the first reducing 10 and the second reducing 20, i.e. completes the first pipeline 1 He
The axially location of second pipe 2 is connected, and is also convenient for dismounting.And then achieve without works such as any installation tool and on-the-spot processing
Sequence, the free-hand connection realized between pipeline.When keeping in repair pipeline, conveniently pulling down assembling pipe joint, this attachment means also may be used
Repetitive cycling uses, and then cost-saved, it is to avoid waste.
Illustrating of above four embodiments only this utility model preferred embodiment, is wanted not as to this utility model
Ask the restriction of protection domain.In every case without departing from other deformation and the modification of this utility model spirit, it will be appreciated that ground is all included in this reality
Within novel protection domain.
