Abstract
The utility model provides the delivery connection that enters of the preposition telescopic sleeve hydraulic oil cylinder of dumping car, comprise hydraulic jack, on the oil inlet hole one of hydraulic jack side, correspondence is provided with connection block, in connection block, be provided with hollow tube, the corresponding oil inlet hole one of hollow tube, on connection block, be radially provided with a plurality of oil inlet holes two that connect with hollow tube, corresponding a plurality of oil inlet holes two are provided with swivel joint on connection block, the inner side of swivel joint is in annular pass of the outer formation of a plurality of oil inlet holes two, and the oil inlet hole of annular pass and swivel joint connects; The both sides of the annular pass of swivel joint are provided with seal ring, and seal ring makes swivel joint and connection block form the environment of relative sealing; On connection block, at swivel joint, be provided with back-up ring outward.The utility model, because annular pass and the oil inlet hole two of swivel joint form a passage of not limitting direction, has been realized the joint of hydraulic jack and has not been limit direction can realize rotation and the connection of 360 °.The interference problem that solves installation process simple in structure, installs also more smooth.
Description
Technical field
The utility model relates to the manufacture field of oil cylinder in dump truck component, and specifically the preposition telescopic sleeve hydraulic oil cylinder of dump truck is connected with hydraulic system high-pressure oil pipe enters delivery connection.
Background technique
The oil inlet and outlet of traditional preposition telescopic sleeve hydraulic oil cylinder of dumping car is straight-through type joint, the high-pressure oil pipe of the direct connecting fluid pressing system of the other end of straight-through type joint, because the mounting point of the fuel tank of each refitting factory is different, the size of adding required fuel tank is also different, when the installing space of hydraulic system is compact, be difficult to have in bar structure the high-pressure oil pipe of steel wire to be bent to a suitable direction with joint couples together, workman operates harder, and also inconvenience is installed.
Summary of the invention
The purpose of this utility model is in order to solve when self-unloading vehicle hydraulic system installing space is compact and the problem of versatility, the preposition telescopic sleeve hydraulic oil cylinder of dumping car enter delivery connection.
The technical solution of the utility model is for this reason, the preposition telescopic sleeve hydraulic oil cylinder of dumping car enter delivery connection, comprise hydraulic jack, on the oil inlet hole one of hydraulic jack side, correspondence is provided with connection block, in connection block, be provided with hollow tube, the corresponding oil inlet hole one of hollow tube, it is characterized in that: on described connection block, be radially provided with a plurality of oil inlet holes two that connect with hollow tube, corresponding a plurality of oil inlet holes two are provided with swivel joint on connection block, the inner side of swivel joint is in annular pass of the outer formation of a plurality of oil inlet holes two, and the oil inlet hole of annular pass and swivel joint connects.
Improvement to such scheme is: the both sides of the annular pass of swivel joint are provided with seal ring, and seal ring makes swivel joint and connection block form the environment of relative sealing.
Improvement to such scheme is: on connection block, at swivel joint, be provided with back-up ring outward.
Beneficial effect:
In the utility model because connection block footpath is upwards provided with a plurality of oil inlet holes two that connect with hollow tube, the oil circuit that has guaranteed oil inlet hole two and hollow tube is common, the annular pass of swivel joint and oil inlet hole two form a passage of not limitting direction simultaneously, now the oil inlet hole of tubular rotary joint is not in any direction, it is unimpeded that the oil duct of oil inlet hole, annular pass, oil inlet hole two, hollow tube, oil inlet hole one keeps, and also just realized the joint of hydraulic jack and do not limit direction can realize rotation and the connection of 360 °.Its interference problem that solves installation process simple in structure, the installation that is is more smooth.
Arranging of seal ring guaranteed the unimpeded and oil-proof of oil duct, mainly plays seal action.
Back-up ring fixedly guaranteed that on connection block, swivel joint can arbitrarily be adjusted direction and be unlikely to come off.
Accompanying drawing explanation
Fig. 1 is assembly schematic diagram of the present utility model.
Fig. 2 is the enlarged diagram that in Fig. 1, A is ordered.
In figure, 1 is hydraulic jack, the 2nd, and connection block, the 3rd, oil inlet hole two, 4th, swivel joint, the 5th, oil inlet hole, the 6th, annular pass, the 7th, seal ring, the 8th, back-up ring, the 9th, filler opening one, 10th, hollow tube.
Embodiment
The utility model as shown in Figure 1, 2.
The universal joint of the preposition telescopic sleeve hydraulic oil cylinder of dumping car, comprise hydraulic jack 1, on the oil inlet hole 1 of hydraulic jack 1 side, correspondence is provided with connection block 2, in connection block 2, be provided with hollow tube 10, the corresponding oil inlet hole 1 of hollow tube 10, connection block 2 footpaths are upwards provided with a plurality of oil inlet holes 23 that connect with hollow tube 10, corresponding a plurality of oil inlet holes 23 are provided with swivel joint 4 on connection block 2, the inner side of swivel joint 4 is in annular pass 6 of the outer formation of a plurality of oil inlet holes 23, and the oil inlet hole 5 of annular pass 6 and swivel joint 4 connects.
The both sides of the annular pass 6 of swivel joint 4 are provided with seal ring 7, and seal ring 7 makes swivel joint 4 and connection block 2 form the environment of relative sealing.
On connection block 2, outside swivel joint 4, be provided with back-up ring 8.
In the utility model because connection block 2 footpaths are upwards provided with a plurality of oil inlet holes 23 that connect with hollow tube 10, the oil circuit that has guaranteed oil inlet hole 23 and hollow tube 10 is common, the annular pass 6 of swivel joint 4 and oil inlet hole 23 form a passage of not limitting direction simultaneously, now the oil inlet hole 5 of tubular rotary joint 4 is not in any direction, it is unimpeded that the oil duct of oil inlet hole 5, annular pass 6, oil inlet hole 23, hollow tube 10, oil inlet hole 1 keeps, and also just realized the joint of hydraulic jack and do not limit direction can realize rotation and the connection of 360 °.Its interference problem that solves installation process simple in structure, the installation that is is more smooth.
Arranging of seal ring 7 guaranteed the unimpeded and oil-proof of oil duct, mainly plays seal action.
Back-up ring 8 fixedly guaranteed that on connection block 3, swivel joint 4 can arbitrarily be adjusted direction and be unlikely to come off.
