Description
Technical field
The utility model is related to bellows field, in particular to a kind of bellows pipe sleeve and bellows pipeline.
Background technology
Bellows refers to the tubular elastomeric sensing element connected into along folding retractable direction with foldable wrinkle piece, is have
The housing of the cylinder-shaped thin wall wrinkle of multiple transverse waves, bellows be can serve as sealing off element, and two media is separated
Come or prevent harmful fluids access arrangement.It is also used as compensating element, using the changeability compensation apparatus of its volume
Temperature difference.Sometimes two elastic connection joints of part etc. are also used as.But, when bellows is more severe in environment
Situation when, be easily caused pipe split, damaged and corrosion etc., the service life of bellows is reduced, currently in order to effectively protecting ripple
Pipe, typically the outer wall in bellows coats layer protective layer.
Inventor has found that existing protective layer at least has the following disadvantages under study for action：Existing protective layer coat after just
It is difficult to remove, even if also can be by bellows to destruction after mandatory dismantling.
Utility model content
The purpose of this utility model is to provide a kind of bellows pipe sleeve, to improve existing protective layer installation and removal not
Convenient problem.
The purpose of this utility model is to provide a kind of bellows pipeline, to improve existing protective layer installation and removal not
Convenient problem.
What the utility model was realized in：
Based on the first above-mentioned purpose, the utility model provides a kind of bellows pipe sleeve, including body and interface arrangment,
The interface arrangment includes sliding block and the fixed block for fixing the sliding block, and the fixed block is installed on the body, described
Sliding block is slidably connected with the body, and the sliding block is slided relative to the body and makes one end of the sliding block towards the body
The center of circle be close to.
The bellows pipe sleeve that the utility model is provided by sliding slider, can make sliding block pushed against with bellows main body or
Loosen, therefore to ensure convenience of the bellows pipe sleeve in installation and removal, this mode simple structure is mounted and dismounted all very
Convenient, can have effectively prevent the problems such as rupture of bellows main body, damaged or corrosion, so as to extend the use of bellows main body
Life-span.
Further, ratchet is provided with the sliding block, the ratchet is connected in the fixed block, and the ratchet order is described
Slide in the direction that sliding block cannot be directed away from the center of circle of the body.
In the positive slip of sliding block, even if sliding block is near the center of circle of body, ratchet will not be impacted to the slip of sliding block,
After sliding slider makes sliding block by bellows main body clamping, because ratchet is against on fixed block, sliding block cannot reverse slide,
Can be very good that bellows main body is fixed and protected.
Further, the one side of the fixed block dorsad ratchet is set to inclined-plane, and the inclined-plane is along the fixed block
Rotation direction slope inwardly.
The setting on inclined-plane makes sliding block more smooth laborsaving when forward direction is slided.
Further, one end of the fixed block rotates with the body and is connected, and the fixed block is relative to the body
The axial line of rotation is vertical with the axial line of the body, the other end of the fixed block and the body clamping.
When bellows pipe sleeve is installed in bellows main body, fixed block can be opened can also be without opening, now
Sliding block can be carried out positive slip, and bellows main body is fixed；When needing to remove body from bellows main body,
Fixed block only need to be opened, fixed block cancels the limitation to sliding block when being rotated along body, now sliding block can be with reverse slide, side
Just body is removed from bellows main body.
Further, the bellows pipe sleeve also includes elastic component, and the elastic component is installed on the body, the elasticity
Part makes the trend that there is the sliding block center of circle for being directed away from the body to slide.
This bellows pipe sleeve is that, using sliding block slid inward, sliding block takes the space between body and bellows main body,
Clamping is allowed to, therefore when removing, sliding block is relatively tight with what body and bellows main body were all blocked, and sliding block reverse slide is more difficult,
Elastic component can help people to apply the power for making sliding block reverse slide to sliding block when fixture is opened, and make bellows pipe
Enhanced convenience when being enclosed within dismounting.
Further, the elastic component is in the spring of compressive state.
The many potential energy of the spring-compressed of compressive state, when fixture is opened, can rapidly discharge potential energy, and, sliding block
Card it is tighter when, the active force of spring is bigger, and help during for sliding block being removed is also bigger.
Further, the first opening and the second opening are provided with the body, first opening is along the body
Circumferentially extending, second opening radially extending along the body, and first opening and second open communication；Institute
State sliding block and be installed on first opening, the fixed block is installed on second opening.
First opening and the second opening can facilitate the activity of interface arrangment.
Further, the interface arrangment is set to two groups, and interface arrangment described in two groups is respectively arranged at the body
Two ends.
Two groups of interface arrangments make bellows pipe sleeve more be consolidated with what bellows main body was fixed.
Further, the length of the body is more than 30 centimetres.
Bellows main body can now be formed and be effectively protected.
Based on the second above-mentioned purpose, the utility model additionally provides a kind of bellows pipeline, including bellows main body and
Bellows pipe sleeve as described above, the bellows pipe sleeve is installed on the bellows main body.
The bellows pipe sleeve that the utility model is provided by sliding slider, can make sliding block pushed against with bellows main body or
Loosen, therefore to ensure convenience of the bellows pipe sleeve in installation and removal, this mode simple structure is mounted and dismounted all very
Convenient, can have effectively prevent the problems such as rupture of bellows main body, damaged or corrosion, so as to extend the use of bellows main body
Life-span.
Compared with prior art, the beneficial effect of the utility model realization is：
The bellows pipe sleeve that the utility model is provided by sliding slider, can make sliding block pushed against with bellows main body or
Loosen, therefore to ensure convenience of the bellows pipe sleeve in installation and removal, this mode simple structure is mounted and dismounted all very
Convenient, can have effectively prevent the problems such as rupture of bellows main body, damaged or corrosion, so as to extend the use of bellows main body
Life-span.
