Description
Technical field
The utility model relates to a kind of connecting tubes.
Background technique
A kind of existing connecting tube, includes tube body, and tube body is equipped with input end, outlet end, the outlet end of tube body with
When external pipe connects, medium leaks in order to prevent, needs close to outlet end position setting sealing ring in tube body, sealing ring is remote
Extending internally from outlet end side has annular flange, and inboard wall of tube body is equipped with the seal groove to match with sealing ring, and sealing ring is set
In in seal groove, when this sealing ring setting can make external pipe be inserted into outlet end, annular flange can be with external pipe end
Face sealing, improves sealing effect.But the connecting tube of this structure, when medium is exported by outlet end, medium is easily accessible close
Between seal and seal groove, impact force is generated to sealing ring, so that sealing ring is deviate from, is used for a long time, so that sealing ring makes
Short with the service life, poor sealing effect is not withstand pressure.
Summary of the invention
The purpose of this utility model: in order to overcome the drawbacks of the prior art, the utility model provides a kind of connecting tube,
Medium can be effectively avoided, impact is generated to sealing ring, so as to prevent sealing ring from deviating from seal groove, extends making for sealing ring
With the service life, sealing effect is good, high pressure resistant.
The technical solution of the utility model includes: a kind of connecting tube, includes tube body, tube body is equipped with input end, outlet end, pipe
Close to outlet, end position is equipped with sealing ring in vivo, and sealing ring extends internally far from outlet end side annular flange, inboard wall of tube body
It is equipped with the seal groove to match with sealing ring, sealing ring is placed in seal groove, it is characterised in that: also fixed in the tube body
There is casing, casing is bonded with inboard wall of tube body, and the casing extends in sealing ring to the outlet extreme direction of tube body, is extended to close
The outer wall of casing in seal is bonded with the inner wall of annular flange.
By adopting the above technical scheme, due to casing extends in sealing ring and extend to the outer wall of the casing in sealing ring with
The inner wall of annular flange is bonded, and such casing can prevent medium from sealing ring far from entering between outlet end side and seal groove
In seal groove, impact is generated so as to be effectively prevented from medium to sealing ring, prevents sealing ring from deviating from, to a certain extent can
The service life for extending sealing ring, so that the sealing effect of sealing ring is good.
The further setting of the utility model: the casing and inboard wall of tube body is interference fitted.
Using above-mentioned further setting, so that casing is easier for installation, it is more stable, firm to position.
The further setting of the utility model: step is equipped in the tube body, the casing is far from outlet end one
Side pressure is located on step.
Further be arranged using above-mentioned, the step of setting can when installing casing, using step as support portion, thus
Casing is assembled, is assembled more convenient.
The further setting again of the utility model: inner wall of the sealing ring close to outlet end side is equipped with slope.
Using above-mentioned setting further again, sealing ring is damaged when can prevent in external pipe insertion sealing ring in slope.
The further setting again of the utility model: the outlet end of tube body is in horn-like setting.
Using above-mentioned setting further again, it can be convenient in this way and external pipe be inserted into outlet end, it is easy for installation, it is not easy
Damage pipeline.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model specific embodiment；
Fig. 2 is the main view of the utility model specific embodiment；
Fig. 3 is A-A structure sectional view in Fig. 2.
Specific embodiment
It include tube body 1 as shown in Figure 1-3, a kind of connecting tube, tube body 1 is equipped with input end 2, outlet end 3, in tube body 1
It is equipped with sealing ring 4 close to 3 position of outlet end, sealing ring 4 extends internally far from 3 side of outlet end annular flange 41, in tube body 1
Wall is equipped with the seal groove 11 to match with sealing ring 4, and sealing ring 4 is placed in seal groove 11, is fixedly provided in the tube body 1
Casing 5, casing 5 are bonded with 1 inner wall of tube body, and the casing 5 extends in sealing ring 4 to 3 direction of the outlet end of tube body 1, are prolonged
The outer wall for extending to the casing 5 in sealing ring 4 is bonded with the inner wall of annular flange 41, and such casing 5 can prevent medium from sealing
Circle 4 between 3 side of outlet end and seal groove 11 far from entering in seal groove 11, so as to be effectively prevented from medium to sealing ring
4 generate impact, prevent sealing ring 4 from deviating from, can extend the service life of sealing ring 4 to a certain extent, so that sealing ring 4
Sealing effect it is good, it is high pressure resistant.
In the utility model specific embodiment, the casing 5 and 1 inner wall of tube body are interference fitted, so that casing 5
Easier for installation, it is more stable, firm to position.Other fixed forms can certainly be used, such as are threadedly engaged, but its
Installation is inconvenient, is easy to produce loosening and is easily damaged component.
In the utility model specific embodiment, step 12 is equipped in the tube body 1, the casing 5 is far from outlet end 3
Side is pressed on step 12.By the step 12 of setting can when installing casing 5, using step 12 as support portion, thus
Casing 5 is assembled, is assembled more convenient.
In the utility model specific embodiment, inner wall of the sealing ring 4 close to 3 side of outlet end is equipped with slope 42, slope
42 damage sealing ring 4 when can prevent in external pipe insertion sealing ring 4；The outlet end 3 of tube body 1 is in horn-like setting, in this way
It can be convenient and external pipe is inserted into outlet end 3, it is easy for installation, it is hardly damaged pipeline.
