Abstract
The utility model belongs to joint appliance technology, more particularly to a kind of sealing mechanism of joint.The utility model discloses the sealing mechanism of joint, the sealing mechanism of joint includes parent and special-shaped ring seal, through hole is offered inside described parent, through hole is up-narrow and down-wide, the bottom of parent is male member, it is located on special-shaped ring seal at the annular groove and the internal projection of male member fits, annular groove communicates with through hole.The beneficial effects of the utility model are：Pass through the respective outer side edges between Novel sealing ring and parent so that press and complete without very big strength can in pressing, and cavity pressure is higher, and sealing effectiveness is more preferable.
Description
Technical field
The utility model belongs to joint appliance technology, more particularly to a kind of sealing mechanism of joint.
Background technology
Joint is to be applied to the water delivery occasions such as agricultural irrigation, Urban Waterlogging.Joint is by public body portion, parent fraction, O-ring
The wrench assembly of seal, the public body of connection and parent is formed, and spanner is arranged on public body, and O-ring seal is arranged on parent endoporus.
O-ring seal is solid rubber parts, makes O-ring that shape occur on spanner in use, very big power must be acted in pressing
Become, can be only achieved the effect of sealing, for big specification joint when in use, must just borrow boosting-rod and can be only achieved to press
This requirement.
The content of the invention
The purpose of this utility model is solve the problems, such as techniques discussed above, there is provided a kind of to pass through Novel sealing ring and mother
Respective outer side edges between body so that press and complete without very big strength can in pressing, and cavity pressure is higher, and it is close
The sealing mechanism of the more preferable joint of effect is sealed, its technical scheme is as follows：
The sealing mechanism of joint, it is characterised in that the sealing mechanism of joint includes parent and special-shaped ring seal, described
Parent inside offer through hole, through hole is up-narrow and down-wide, and the bottom of parent is male member, is offered on the outside portion of male member outer recessed
Groove, inside portion and the external groove corresponding position of male member are provided with internal projection；Male member is internally provided with special-shaped ring seal, abnormity
Endoporus is offered in ring seal, the lateral wall of special-shaped ring seal at the bottom of male member madial wall with fitting, abnormity
The upper end surface of ring seal offers annular groove, is located on special-shaped ring seal at annular groove and male member
Internal projection fits, and annular groove communicates with through hole.
Preferred embodiment is to offer inner groovy on the madial wall of male member.
Preferred embodiment is that gap is left in the lower surface of special-shaped ring seal and the bottom of male member.
Preferred embodiment is to be provided with angular protrusions on special-shaped ring seal.
The sealing mechanism of joint provided by the utility model, when in use, external groove are to be used to wrench assembly connect
Parent is used so that connection has more preferable stability.The cooperation of internal projection and special-shaped ring seal can cause in male member
Cavity is left at top, so that there is better seal performance during pressurization.The effect of annular groove is cavity pressure
Higher, sealing effectiveness is more preferable.
The setting of angular protrusions of the present utility model causes special-shaped ring seal when being pressurized, can ensure annular groove
It is pressurized balanced, so as to ensure sealing property.
The beneficial effects of the utility model are：Pass through the respective outer side edges between Novel sealing ring and parent so that pressing
Strength can pressing very big Shi Buyong is completed, and cavity pressure is higher, and sealing effectiveness is more preferable.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the schematic diagram of special-shaped ring seal.
Embodiment
With reference to Fig. 1 and Fig. 2 specific illustrative embodiments：
The sealing mechanism of joint, the sealing mechanism of joint include parent 1 and special-shaped ring seal 2, in described parent 1
Portion offers through hole 3, and through hole 3 is up-narrow and down-wide, and the bottom of parent 1 is male member 4, and external groove 5 is offered on the outside portion of male member 4,
The inside portion of male member 4 is provided with internal projection 6 with the corresponding position of external groove 5；Male member 4 is internally provided with special-shaped ring seal 2, different
Endoporus 7 is offered in shape ring seal 2, the lateral wall of special-shaped ring seal 2 with being fitted at the bottom of male member madial wall,
The upper end surface of special-shaped ring seal 2 offers annular groove 8, is located on special-shaped ring seal 2 at annular groove 8
Fitted with the internal projection 6 of male member, annular groove 8 communicates with through hole 3.
Preferred embodiment is that inner groovy 9 is offered on the madial wall of male member 4.
Preferred embodiment is that gap is left in the lower surface of special-shaped ring seal 2 and the bottom of male member.
Preferred embodiment is to be provided with angular protrusions 10 on special-shaped ring seal 2.
Specifically used when, the upper end of public body is deep at the lower end of parent, from the endoporus of special-shaped ring seal
In pass.Special-shaped ring seal is between public body and parent, so as to play sealing function.When being pressurized, pressure acts on
On special-shaped ring seal, and there is annular groove so that be pressurized bigger, its sealing property is also better.
Claims (4)
