Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail:
As shown in Figure 1; The utility model includes the hydraulic oil pipe 1 and anti-leak joint of some boundlings; Said anti-leak joint is combined by inner cone joint 2 and outside cone joint 3; Said hydraulic oil pipe 1 is provided with wire size and is connected with inner cone joint 2 or outside cone joint 3 respectively at its two ends, is connected with outside cone joint 3 through inner cone joint 2 according to corresponding wire size between per two bundle hydraulic oil pipes 1.
As shown in Figure 2; The inner cone joint 2 and the outside cone joint 3 of anti-leak joint include hollow projectile cartridge spring abutment 21, return spring 22 and conehead spool 23 respectively; Return spring 22 is sheathed on conehead spool 23 terminal shafts and is arranged on the hollow projectile cartridge spring abutment 21; Outside cone joint 3 outer periphery are equipped with attaching nut 31, and inner cone joint 2 and outside cone joint 3 ends to be joined are respectively arranged with conical indentation 24 with corresponding protruding 33, and outside cone joint 3 inserts in the inner cone joints 2 and closely cooperates during joint.The outside of outside cone joint 3 tapered protrusion 33 also is provided with O RunddichtringO 32.
Like Fig. 3 and shown in Figure 4, hydraulic oil pipe 1 outer periphery of every constriction bundle is equipped with outer pillar 4, and the outer periphery of outer pillar 4 is equipped with the outer card pipe 5 that protects.Hydraulic oil pipe 1 adopts high-pressure rubber pipe or seamless steel pipe, and its quantity is confirmed according to actual needs.Pillar 4 outside the outer periphery of every bundle hydraulic oil pipe 1 is equipped with, and can or twine adhesive tape by crude rubber pipe, thick plastic tube, thick steel pipe, winding moccasin, winding steel wire and form.The outer periphery of pillar 4 is equipped with the outer card pipe 5 that protects outside, according to how many parts of hydraulic oil pipe 1 length decision, at least two.Wire size is designed to be made up of letter and 1 to 2 Arabic numerals, and permanent the maintenance.Attention will have the technology that can expand with heat and contract with cold crooked at the two end part of long hydraulic oil pipe 1.When seamless steel pipe was made oil pipe, its wall thickness and internal diameter will meet the pressure requirement of hydraulic system; When high-pressure rubber pipe was made oil pipe, its steel wire number of plies and internal diameter also will meet the pressure requirement of hydraulic system.The layout of boundling oil pipe will meet the spatial requirement of equipment, and can make corresponding bending, arranges rational and orderly more so that make.
The utility model is described as a specific embodiment below in conjunction with Fig. 1 and Fig. 2:
Wire size for boundling hydraulic oil pipe 1 is provided with as shown in Figure 1; Comprise 5 hydraulic oil pipes 1 in the boundling of wire size A1; That be connected in 5 hydraulic oil pipe 1 two ends is respectively outside cone joint A01, A02, A03, A04, A05, A11, A12, A13, A14, A15; Comprise 5 hydraulic oil pipes 1 in the boundling of wire size A2; That be connected in 5 hydraulic oil pipe 1 two ends is respectively inner cone joint A21, A22, A23, A24, A25, A31, A32, A33, A34, A35, and wire size boundling oil pipe prevents misconnection to meet A21 such as A11 by the wire size butt joint during use; So the outside cone joint on the A1 wire size boundling hydraulic oil pipe 1 respectively with A2 wire size boundling hydraulic oil pipe 1 on the inner cone joint be connected, by that analogy whole oil circuit is connected.The number of boundling is confirmed according to the length of whole hydraulic circuit.
As shown in Figure 2; The inner cone joint 2 of anti-leak joint is with after outside cone joint 3 is connected; Coupling nut 31 links together inner cone joint 2 and outside cone joint 3 closely; Move after the extruding of two conehead spool 23 evagination positions separately return spring 22 is compressed, the tapering of conehead spool 23 is sealed and is opened, and hydraulic oil connects and flows through.Lean on 24o conical surface seal between inner cone joint 2 and the outside cone joint 3 this moment, and the O type circle seal ring 32 between two conical surfaces has increased sealing together again, makes sealing more reliable.
Attaching nut 31 with the anti-leak joint during dismounting turns on, and inner cone joint 2, outside cone joint 3 separate, and each comfortable return spring 22 spring force effect outwards extruding down, and hydraulic fluid port is shut in the tapering of conehead spool 23, and fluid is not revealed, and oil circuit is closed.When the anti-leak joint breaks off, the little conical surface of oilhole and conehead spool 23 conical surface seals of outside cone joint 3 and inner cone joint 2, both conical surfaces make sealing more reliable through to grinding disposing, and assurance hydraulic oil can not revealed.
