Description

A kind of sealed connector of hydraulic system oil circuit
Technical field
The utility model is related to hydraulic system accessories technical fields, and in particular to a kind of hydraulic system oil circuit is sealed to be connect Head.
Background technology
Hydraulic technique is applied by today's society in industry-by-industry, is the important component in mechanical equipment.And hydraulic pressure System pipe fitting is the critical elements of conducting operations liquid in hydraulic system, with hydraulic coupler by oil pipe and oil pipe and other Element connects, and constitutes the pipe-line system in mechanical equipment.
Current hydraulic coupler is mainly made of nut, joint core and sleeve, when the connection of nut and joint core By withholding nut on the annular groove of joint core, nut is set securely to be connect by material deformation with joint core, then by reinforcing Structure is fixedly connected, and such as application No. is a kind of hydraulic coupler of 200820184952 .3, passes through positioning wire And the nut that hole matches is penetrated to be attached with joint core with positioning wire, this mode passes through similar mutual between structure The mode of lock is fastened, and is increased although can reduce and withhold cost caused by mode, coupling part defective tightness, sealing Property it is relatively poor, be easy to loosen because of outer force effect, be susceptible to oil leakage phenomenon, and then the effect of influence hydraulic power transmission Rate.
Utility model content
The technical issues of the utility model is solved is to provide a kind of sealed connector of hydraulic system oil circuit, in solution State the defects of technical background.
The technical issues of the utility model is solved is realized using following technical scheme:
A kind of sealed connector of hydraulic system oil circuit, including nut and joint core, one end of the joint core penetrate In nut, and there are one indent cascaded surfaces for setting on penetrating nut portion, and are not penetrated outside the part of nut in joint core Side is then fixed there are one sleeve, and being connected on the indent cascaded surface, there are one the dish-shaped disc of two rank cascaded surface of band, the dishes It forms external screw thread face on the outer cylinder of the upper rank cascaded surface of disc, and is screwed on fixation by flank in addition and nut;And institute It states sleeve and forms external screw thread face on the outer cylinder by nut side, and be connected by flank in addition that there are one be fixed Seat, the seat that is fixed are oppositely arranged with dish-shaped disc, and be fixed between seat and dish disc be also clamped with it is stainless Steel elastomeric pad.
In the present invention, the dish-shaped disc and the indent cascaded surface of joint core are connected through a screw thread mode and fix company It connects.
In the present invention, the sum of the upper rank thickness of the dish-shaped disc and the thickness of indent cascaded surface of joint core with The consistency of thickness of the non-deformation position of joint core.
In the present invention, the joint core is provided with concave ring surface in a circle in the position for the sleeve that is connected, and the set Cylinder is then molded directly within the interior concave ring surface position, to prevent sleeve to be subjected to displacement on the outer cylinder of joint core.
In the present invention, it is fixed the number for the stainless steel elastomeric pad being arranged between seat and dish-shaped disc It is 1 ~ 2.
In the present invention, being fixed on the medial surface of seat and sleeve connection part also molding, there are one rubber washers Slot, and the stability being fixed when seat is screwed on fixed can be effectively improved by installing rubber washer additional in rubber pad ring recess, and It can effectively reduce and be screwed on the influence of stability under severe assembly environment to being fixed seat.
Advantageous effect:A kind of sealed connector of hydraulic system oil circuit of the utility model is carried out again by butt joint part Design, can effectively ensure that the stability of each component during the connection process, be fixed seat, dish-shaped disc and stainless steel bomb The collective effect of property pad ensures stability that nut is connected with joint core, promotes its connective stability, while can effectively avoid It is loosened caused by being used for a long time, greatly improves the sealing effect of joint, ensure that efficiency of transmission, reduce resource wave Take.
Description of the drawings
Fig. 1 is the schematic diagram of the preferred embodiment of the utility model.
Wherein:1, nut;2, dish-shaped disc;3, stainless steel elastomeric pad;4, it is fixed seat;5, rubber washer;6, it covers Cylinder;7, joint core.
Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to a kind of sealed connector of hydraulic system oil circuit of Fig. 1, in the present embodiment, sealed connector includes nut 1 And joint core 7, wherein nut 1 is consistent with the nut structure of conventional seals connector, is internal thread nut, and joint core 7 is being worn Enter the position setting in nut there are one indent cascaded surface, be provided with concave ring surface in a circle on tube body on the outside of the indent cascaded surface, And in the interior concave ring surface position molding there are one the size sleeve 6 consistent with interior concave ring surface size, this structure setting can be effective The stability for ensureing sleeve 6, prevents sleeve to be subjected to displacement on the outer cylinder of joint core 7, and in the sleeve 6 by 1 side of nut Outer cylinder on form external screw thread face.
When in use, the external screw thread surface cover dress for first passing through sleeve 6 is fixed seat 4 to the sealed connector of the present embodiment, should Be fixed seat 4 and be directly screwed on and be fixed on sleeve 6, and on being fixed medial surface of the seat 4 with 6 coupling part of sleeve also at Type can be effectively improved by installing rubber washer 5 additional in rubber pad ring recess and be fixed seat and be screwed on 4 there are one rubber pad ring recess Stability when being screwed on fixed, and can effectively reduce and be screwed on the influence of stability under severe assembly environment to being fixed seat 4.And After the completion of being fixed seat 4 in fixation, upper stainless steel elastomeric pad 3 is padded in indent cascaded surface and between being fixed seat 4, so It is set with dish-shaped disc 2 in indent cascaded surface position again afterwards, and dish-shaped disc 2 and the indent cascaded surface of joint core 7 are connected by screw thread The mode of connecing is fixedly connected, and the sum of the upper rank thickness of dish-shaped disc 2 and the thickness of indent cascaded surface of joint core 7 and joint core 7 Non- deformation position consistency of thickness to ensure that the joint core 7 equipped with dish-shaped disc 2 can be screwed in nut 1 i.e. by external screw thread face Complete assembly.
