Abstract
The present invention announces a kind of telescopic sealed attachment part for pressure fluid conduit, belongs to fluid circuit interconnection technique.Include the joint I and joint II of cylindrical shape, the one end of joint I is slidably mounted in joint II, and the outer end of joint I and joint II is respectively equipped with interface；Sealing ring is installed between the joint I inner outer circumference surface and the inwall of joint II；Dust ring is installed between the inner inwall of the joint II and the outer circumference surface of joint I.Inventive joint I and joint II can seal in certain limit relative motion and reliably at an arbitrary position；This Regulation mechanism causes, when the present invention is added among the parts of series connection, the parts that can make to connect between two hydraulic fluid ports can be sealingly connected reliably in relative to the larger size range of processing and assembly error.
Description
Technical field
The present invention relates to fluid circuit connector, specifically a kind of telescopic sealed attachment for pressure fluid conduit
Part.
Background technology
In pressurized fluid system, coupled between two hydraulic fluid ports that spacing is fixed with hard tube, pipe seal, gone here and there when between two hydraulic fluid ports
When the more whole system of parts of connection is more complicated, usually because the size cumulative errors of processing and installation, cause all series connection
Parts overall length it is overproof, thus can not with both ends be coupled hydraulic fluid port couple.
Under prior art, to reduce cumulative errors, there are two approach, first, size essence of the design higher than conventional criteria part
Degree；Second, parts thereof scene is with work.Its shortcoming is：Design higher than conventional criteria part parts size precision, cost compared with
Greatly；Parts thereof scene is low with work, efficiency.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of telescopic sealed attachment portion for pressure fluid conduit
Part.
The present invention is achieved through the following technical solutions：A kind of telescopic sealed attachment portion for pressure fluid conduit
Part, including cylindric joint I and joint II, the one end of joint I are slidably mounted in joint II, the outer end of joint I and joint II
It is respectively equipped with interface；Sealing ring is installed between the joint I inner outer circumference surface and the inwall of joint II；In the joint
Dust ring is installed between the outer circumference surface of II inner inwall and joint I.
It is further：The deep gouge of two circumferential formulas is provided with the inner outer circumference surface of the joint I；The sealing ring is
O-ring, two are shared, be separately mounted in two deep gouges on joint I.
The deep gouge of a circumferential formula is provided with the inner inwall of the joint II, the dust ring is arranged on joint II
In deep gouge.
The outer end interface of the joint II is provided with external screw thread and inner bore chamfering.
The inwall of the joint II is provided with the circumferential formula shelves platform of the limitation inner end positions of joint I.
The outer end of joint I is welded with outer connector；The outer end interface of the outer connector is provided with external screw thread and inner bore chamfering；
Outer connector outer circumference surface is provided with hexagonal step.
Compared with prior art, the beneficial effects of the invention are as follows：Joint I and joint II can be in certain limit relative motions simultaneously
And can reliably it seal at an arbitrary position；This Regulation mechanism causes, can when the present invention is added among the parts of series connection
The parts for making to connect between two hydraulic fluid ports can reliably seal connection in relative to the larger size range of processing and assembly error
Connect.

Embodiment
It is the specific embodiment of the present invention below, in conjunction with accompanying drawing, the present invention will be further described.
As shown in figure 1, a kind of telescopic sealed attachment part for pressure fluid conduit, including cylindric joint
I 1 and joint II 4, the one end of joint I 1 be slidably mounted in joint II 4, joint I 1 and joint II 4 are that axis hole cooperates.Connecing
Sealing ring 3 is installed between first I 1 inner outer circumference surfaces and the inwall of joint II 4, ensures joint inner sealing, is specifically：Joint
The deep gouge of two circumferential formulas is provided with I 1 inner outer circumference surfaces, sealing ring 3 is O-ring, shares two, is separately mounted to joint
In two deep gouges on I 1.Dust ring 2 is installed between the inner inwall of joint II 4 and the outer circumference surface of joint I 1, it is dust-proof
The outside dirt of the barrier of circle 2 enters fit clearance, is specifically：The deep gouge of a circumferential formula, institute are provided with the inner inwall of joint II 4
Dust ring 2 is stated in the deep gouge on joint II 4.The outer end interface of joint II 4 is provided with external screw thread and inner bore chamfering, joint II
4 inwall is provided with the circumferential formula shelves platform of the limitation inner end positions of joint I 1.The outer end of joint I 1 is welded with outer connector 1-1；Outer connection
The outer end interfaces of head 1-1 are provided with external screw thread and inner bore chamfering；Outer connector 1-1 outer circumference surfaces are provided with hexagonal step 1-2, step
1-2 design is easy to screw thread to tighten.
Joint I 1 and the interface of the outer end of joint II 4 can be also used as defined in the standards such as ISO 8434-1 or ISO 11926-1
Joint sealing draw bail.
