Abstract
The utility model discloses a rotary pipe joint assembly of a hydraulic system, which comprises a joint component, a sleeve (4) and a hose (5). The joint component is composed of a nut (1), a sealing ring (2) and a joint core (3), the joint core (3) extending out of the sleeve (4) is provided with a clamping groove, one end of the nut (1) is provided with a retaining ring for clearance fit with the clamping groove of the joint core (3), the other end of the nut (1) is provided with outer threads connected with a cylinder, an inner hole of the nut (1) is a stepped hole, and the sealing ring (2) is disposed in a closed cavity formed by the inner hole of the nut (1) and the outer surface of the joint core (3). By utilizing the structure, the hose does not rotate along with nut tightening, and thereby the rotary pipe joint assembly is simple in process, saves a transitive joint, facilitates installation and maintenance and reduces the cost.
Description
Technical field
The utility model relates to hydraulic system swivel joint assembly.
Background technique
Hydraulics is used in all trades and professions of current society widely, as engineering machinery, farm machinery, shipbuilding, military weaponry, space flight and aviation industry or the like every field.And pipe joint is the critical elements of conduction working solution in the hydraulic system, with orderly the coupling together of each element of oil pipe, constitutes pipe-line system with pipe joint.Existing hydraulic system swivel joint assembly comprises adapter piece 6, sleeve 4 and flexible pipe 5, and as shown in Figure 2, an end of flexible pipe 5 and adapter piece 6, sleeve 4 form one, and flexible pipe can rotate along with turning of joint when practical set, causes the assembling difficulty.So during the assembling of traditional joint, need transit joint of configuration to play a transition role, be connected with adapter piece with transit joint earlier, link to each other with cylinder body by the transit joint nut again, so not only installation and maintenance inconvenience, and also cost is higher.
The model utility content
Technical problem to be solved in the utility model is: a kind of hydraulic system swivel joint of being convenient to installation and maintenance, reducing cost is provided.
Solve this technical problem, the technical solution of the utility model is: a kind of hydraulic system swivel joint assembly, comprise adapter piece, sleeve and flexible pipe, described adapter piece is made up of nut, seal ring and joint core, described joint core stretches out sleeve and has draw-in groove outward, one end of nut has the clasp with joint core draw-in groove Spielpassung, the other end of nut has the outside thread that links to each other with cylinder body, the endoporus of nut is a step hole, and described seal ring is arranged in the enclosed cavity that the endoporus of nut and joint core outer surface form.
Described seal ring is an O type circle.
The utility model hydraulic coupler assembly adopts such structure, reach gapped connection the between nut and the joint by nut and withholding of joint, nut can freely rotate on joint, by seal ring and joint core, cooperation between the nut, reach sealing purpose, because seal ring is in nut and joint enclose inside space, can not cause seal ring to depart from or obscission, effectively avoided the integrally-built deficiency of prior art, when having reached tightening nuts, flexible pipe is not along with rotation, technology is simple, saved transit joint, convenient for installation and maintenance, reduced cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model hydraulic system swivel joint assembly is done explanation in further detail;
Fig. 1 is the utility model hydraulic system swivel joint assembly structure schematic representation;
Fig. 2 is the hydraulic system swivel joint assembly structure schematic representation of prior art;
In Fig. 1, Fig. 2,1, nut; 2, seal ring; 3, joint core; 4, sleeve; 5, flexible pipe; 6, adapter piece.
Embodiment
As shown in Figure 1, hydraulic system swivel joint assembly comprises nut 1, seal ring 2, joint core 3, sleeve 4 and flexible pipe 5, nut 1, seal ring 2 and joint core 3 integral connector spares, joint core 3 stretches out and has draw-in groove outside the sleeve 4, one end of nut 1 has the clasp with joint core 3 draw-in groove Spielpassung, the other end of nut 1 has the outside thread that links to each other with cylinder body, the endoporus of nut 1 is a step hole, seal ring 2 is positioned in the enclosed cavity that the endoporus of nut 1 and joint core 3 outer surfaces form, and seal ring 2 can adopt O type circle.
The utility model hydraulic coupler assembly adopts said structure, reach gapped connection the between nut and the joint by nut and withholding of joint, nut can freely rotate on joint, by seal ring and joint core, cooperation between the nut, reach sealing purpose, because seal ring is in nut and joint enclose inside space, can not cause seal ring to depart from or obscission, effectively avoid the integrally-built deficiency of prior art, when having reached tightening nuts, flexible pipe is not along with rotation, accomplished novel structure, soft or hard combined type envelope is close, and technology is simple, has saved transit joint, convenient for installation and maintenance, reduced cost.
Claims (2)
1, a kind of hydraulic system swivel joint assembly, comprise adapter piece, sleeve (4) and flexible pipe (5), it is characterized in that: described adapter piece is by nut (1), seal ring (2) and joint core (3) are formed, described joint core (3) stretches out and has draw-in groove outside the sleeve (4), one end of nut (1) has the clasp with joint core (3) draw-in groove Spielpassung, the other end of nut (1) has the outside thread that links to each other with cylinder body, the endoporus of nut (1) is a step hole, and described seal ring (2) is arranged in the enclosed cavity that the endoporus of nut (1) and joint core (3) outer surface form.
2, hydraulic system swivel joint assembly according to claim 1 is characterized in that: described seal ring (2) is an O type circle.
