The utility model discloses it adopts the interior outer tube that passes through the leg joint as the connector main part to including set up the screwed pipe between the outer tube and adopt inside and outside dog to keep off and connect the design, be used for the adapter of pipeline reducing, and it has convenient to use, easy operation, simple structure, the practicality is strong, characteristics such as low cost.
Description
Technical field
This utility model relates to hydraulic connecting technical field, is specifically related to a kind of reducing union joint.
Background technology
Hydraulic Elements are the vitals of construction machinery product, hydraulic system oil pipe is all that employing presses the form of (folder) plate by tight for the potted component pressure (folder) on pipeline in the interface plane of hydraulic part with hydraulic part interface, thus realizing hydraulic system normal operation；Owing to pressing plate is integrally fixed on the screwed hole of hydraulic part interface machined surface, indirectly the steel pipe interface with sealing ring is pressed on the interface machined surface of hydraulic part by locking pressure plate；On the one hand, locking rear fender and interface surface certainly exist certain gap guarantee potted component and effectively compress；On the other hand, pressing plate belongs to standard component, and the machined surface form of hydraulic part and size are different, and different suppliers have different designs scheme；So the machined surface profile of the outline of pressing plate and hydraulic part is inconsistent, the outline being substantially hydraulic part is bigger than normal, and the structure of inconsistentization not only increases manufacturing process difficulty, too increases artificial simultaneously.
Utility model content
The purpose of this utility model is in that the defect for prior art and deficiency, a kind of simple in construction is provided, a kind of reducing union joint reasonable in design, easy to use, it adopts the inner and outer pipes connected by support as union joint main body, and outer baffle block carries out gear and connects design in being threaded pipe between inner and outer pipes and adopting, obtain the adaptor for pipeline reducing diameter, and it has easy to use, simple to operate, simple in construction, practical, the feature such as with low cost.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of reducing union joint described in the utility model, including interior pipe, support and outer tube, support it is provided with between said inner tube and outer tube, said inner tube outward flange is provided with outer baffle block, it is provided with internal stop inside described outer baffle block, described internal stop is welded with corrugated tubing, is provided with female thread inside described corrugated tubing, and beyond interior pipe.
It is provided with rubber blanket between described internal stop and outer baffle block, the setting of rubber blanket can reduce the collision between internal stop and outer baffle block, simultaneously it is connected by metal rigid connection between internal stop and outer baffle block, closely not good, after rubber blanket, compactness between the two can be increased by the extruding of rubber blanket.
Said inner tube edge is provided with slope, and slope is arranged on interior tube edges place, simultaneously towards tilted, it is possible to increase the fluency of current, reduce hydraulic pressure during reducing, plays a protective role.
After adopting said structure, this utility model has the beneficial effect that this utility model, and it adopts the inner and outer pipes connected by support as union joint main body, and in being threaded pipe between inner and outer pipes and adopting, outer baffle block carries out gear and connects design, obtains the adaptor for pipeline reducing diameter；Adopt the connection of block, the effect that rapid structural is fixing can not only be played, simultaneously easy to make；The welding of corrugated tubing and the pipeline being designed to facilitate two ends, left and right to connect different inner diameters of female thread, it is simple to ensure patency and the sealing of reducing；The design of inner and outer pipes and the consideration of support, not only act as the effect of protection junction, also has volume little simultaneously, collects the advantages such as convenient；And it has easy to use, simple to operate, simple in construction, practical, the feature such as with low cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
As shown in Figure 1, a kind of reducing union joint described in the utility model, including interior pipe 1, support 2 and outer tube 3, support 2 it is provided with between said inner tube 1 and outer tube 3, said inner tube 1 outward flange is provided with outer baffle block 4, is provided with internal stop 5 inside described outer baffle block 4, and described internal stop 5 is welded with corrugated tubing 6, female thread 7 it is provided with inside described corrugated tubing 6, and beyond interior pipe 1.
It is provided with rubber blanket 8 between described internal stop 5 and outer baffle block 4, the setting of rubber blanket can reduce the collision between internal stop and outer baffle block, simultaneously it is connected by metal rigid connection between internal stop and outer baffle block, closely not good, after rubber blanket, compactness between the two can be increased by the extruding of rubber blanket.
Said inner tube 1 edge is provided with slope 9, and slope is arranged on interior tube edges place, simultaneously towards tilted, it is possible to increase the fluency of current, reduce hydraulic pressure during reducing, plays a protective role.
This utility model it adopt the inner and outer pipes connected by support as union joint main body, and outer baffle block carries out gear and connects design in being threaded pipe between inner and outer pipes and adopting, and obtains the adaptor for pipeline reducing diameter；Adopt the connection of block, the effect that rapid structural is fixing can not only be played, simultaneously easy to make；The welding of corrugated tubing and the pipeline being designed to facilitate two ends, left and right to connect different inner diameters of female thread, it is simple to ensure patency and the sealing of reducing；The design of inner and outer pipes and the consideration of support, not only act as the effect of protection junction, also has volume little simultaneously, collects the advantages such as convenient；And it has easy to use, simple to operate, simple in construction, practical, the feature such as with low cost.
The above is only better embodiment of the present utility model, therefore all equivalences done according to the structure described in this utility model patent claim, feature and principle change or modify, and are all included in this utility model patent claim.
