Abstract

The utility model provides a novel hydraulic system pipe joint, including nut and joint core, annular bulge has in the nut, connecting the core and compriseing dabber and core cover, dabber and core cover are put together through threaded connection, the utility model discloses can avoid among the prior art because of the nut with connect the core and withhold the obscission that harmfully causes.

Description

A kind of Novel hydraulic system pipe joint
Technical field
The utility model relates to a kind of pipe joint, is specifically related to a kind of Novel hydraulic system pipe joint.
Background technique
At present, in construction machinery hydraulic system pipeline, hydraulic coupler is wherein critical elements, and oil pump, connecting tube and other elements couple together by pipe joint, and construction machinery hydraulic system is normally worked.The pipe joint of current use is made up of nut 1, joint core 2 and sleeve 3.As shown in Figure 1, nut 1 is withhold on the annular groove of joint core 2 by cold for nut 1 with the connection of joint core 2, and this cold Placement of withholding causes pipe joint quality less stable, in actual applications, often occur that the phenomenon that nut 1 and joint core 2 come off occurs, affect the normal operation of engineering machinery.The model utility of notification number a kind of hydraulic coupler disclosed in CN201246544Y, this model utility adopts between nut and joint core, arranges an axial annular groove, penetrate hole by the steel wire on nut in axial annular groove and penetrate positioning wire, complete the location of nut in joint core, realize not needing crimping equipment to complete the object of nut location, this model utility is for realizing goal of the invention, not only to need on nut and joint core machining shaft to annular groove, also to process steel wire on nut and penetrate hole, complex process, and penetrating hole by steel wire when assembling, to penetrate steel wire in axial annular groove very difficult, lose time, this model utility is higher for completing goal of the invention overall cost.
Summary of the invention
The utility model provides a kind of Novel hydraulic system pipe joint, and described Novel hydraulic system pipe joint processing technology is simple, and ease of assembly, be suitable for promotion and implementation.
Described Novel hydraulic system pipe joint, comprises nut and joint core, and described nut has the annular projection extended internally; Described joint core is made up of mandrel and core retainer plate, and mandrel end has outward extending annular projection; Mandrel and core retainer plate are threaded connection; The internal diameter of the inside annular projection of described nut is less than the external diameter of mandrel end annular projection and the external diameter of core retainer plate.
The utility model Novel hydraulic system pipe joint structure is simple, easily processes, easy to assembly, and constant product quality, almost without the generation of defect ware.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art pipe joint.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the axial sectional view of mandrel described in the utility model.
Fig. 4 is the axial sectional view of core retainer plate described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Fig. 2, Fig. 3, Fig. 4, Novel hydraulic system pipe joint described in the utility model, comprises nut 1 and joint core, and described nut 1 has the annular projection 11 extended internally; Described joint core is made up of mandrel 21 and core retainer plate 22, and mandrel 21 end has outward extending annular projection 211; Mandrel 21 and core retainer plate 22 are threaded connection; The internal diameter of the inside annular projection 11 of described nut is less than the external diameter of mandrel end annular projection 211 and the external diameter of core retainer plate 22.
Described nut 1 in actual applications, is first enclosed within mandrel 21 by Novel hydraulic system pipe joint described in the utility model, then core retainer plate 22 on spiral shell, and the annular projection 11 in such nut 1 is just stuck in by between mandrel 21 end annular projection 211 and core retainer plate 22.
