Abstract
The invention relates to a hydraulic quick joint convenient for mounting, which realizes convenient disengaging and connecting by bare hands. The hydraulic quick joint comprises a jacket joint body (1), a spring (3), a slide sleeve (4), an inner plug joint (8) and a roll ball (6), wherein a closed L-shaped through slot is processed in the slide sleeve (4) along the axis direction of the slide sleeve (4); one end of a positioning pin (9) is arranged in a positioning pin hole of the jacket joint body (1) in an interference mode, and the other end of the positioning pin (9) is inserted in the L-shaped through slot in the slide sleeve (4); the axis of the positioning pin hole is along the radial direction of the jacket joint body (1); when the positioning pin (9) is positioned at the outer end of the L-shaped through slot on the slide sleeve (4), the jacket joint body (1) is disengaged from the inner plug joint (8); and when the positioning pin (9) is positioned at the upper end of the L-shaped through slot, the jacket joint body (1) is connected with the inner plug joint (8). The hydraulic quick joint is suitable for a large-diameter hydraulic quick joint.
Description
Technical field
This patent belongs to the hydraulics field, relates to a kind of hydraulic quick coupling of being convenient to install.
Background technique
Hydraulic quick coupling is to be used on the hydraulic pipe line of frequent dismounting, is a kind of joint that does not need instrument just can realize dismounting.
Use a lot of hydraulic quick couplings in the vehicle power cabin, be used for connecting some oil circuits and water route when being connected in engine room lifting.Existing hydraulic quick coupling is the rapid pipe joint of large latus rectum, the bad installation of rapid pipe joint of large latus rectum, as shown in Figure 1, when rapid pipe joint connects, be that overcoat fittings body 1 is when being connected with interior plug joint 7, need first sliding sleeve 4 to be pushed away left, outer bell and spigot joint 1 is motionless, when interior plug joint 7 is inserted, ball 5 can outwards move, plug joint 7 in inserting simultaneously, and the one-way valve 2 of plug joint 7 inside and the one-way valve 6 of overcoat fittings body 1 inside back down under active force mutually in this moment, mobile round about respectively, make ball fall into the groove of interior plug joint 7, unclamp sliding sleeve 4, sliding sleeve 4 is resetted under the effect of spring 3, with ball is locked live in plug joint 7, finish being connected of overcoat fittings body 1 and interior plug joint 7.
Can find out from above-mentioned action, when connecting, need 3 active forces, one is outer bell and spigot joint 1 power to the right, and another is sliding sleeve 4 power left, is interior plug joint 7 power left at last.Need to provide 3 power with two hands, when rapid pipe joint is smaller, can promote sliding sleeve with forefinger and the thumb of a hand, all the other fingers and palm withstand overcoat fittings body 1, and another hand withstands interior plug joint 7.But when rapid pipe joint is larger, the power of spring 3 is also large, can not promote sliding sleeve 4 with forefinger and thumb, therefore needs two people to cooperate and could install, therefore, existing large latus rectum hydraulic quick coupling is not suitable for the place of little and inconvenient two people operation in space in the vehicle power cabin.
Summary of the invention
The object of the present invention is to provide a kind of hydraulic quick coupling of being convenient to install, be specially adapted to the hydraulic quick coupling of large latus rectum, realized free-handly freeing easily and being connected.
Technological scheme of the present invention is, a kind of hydraulic quick coupling of being convenient to install, this hydraulic quick coupling comprises the overcoat fittings body, spring, sliding sleeve, interior plug joint, ball and locating stud, be processed with sealing " L " shape groove on the described sliding sleeve, be somebody's turn to do " L " shape along the sliding sleeve axial direction, locating stud one end interference is installed in the positioning pin hole of overcoat fittings body, the locating stud the other end is inserted on the sliding sleeve in " L " shape groove, the positioning pin hole axis along the overcoat fittings body radially, when locating stud is positioned at " L " shape groove transverse part outer end on the sliding sleeve, overcoat fittings body and interior plug joint are freed, and when locating stud was positioned at " L " shape groove upper end, the overcoat fittings body was connected with interior plug joint.
Beneficial effect of the present invention, the present invention has adopted the sliding sleeve with " L " shape groove structure, makes hydraulic quick coupling simple in structure, easy to operate, practical, can for the assembling of vehicle and maintenance is saved time and cost.

Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done more specifically to describe.
The hydraulic quick coupling of the present invention a kind of hydraulic quick coupling of being convenient to install, particularly large latus rectum, using the present invention can free-handly connect easily.
As shown in Figure 3, the present invention is simple and practical, and embodiment is that a kind of hydraulic quick coupling of being convenient to install comprises overcoat fittings body 1, spring 3, sliding sleeve 4, interior plug joint 7 and ball 5.This hydraulic quick coupling also comprises locating stud 8, namely install locating stud 8 additional in existing rapid pipe joint, simultaneously be processed with sealing " L " shape groove at sliding sleeve 4, be somebody's turn to do " L " shape along sliding sleeve 4 axial directions, locating stud 8 one end interference are installed in the positioning pin hole of overcoat fittings body 1, locating stud 8 the other ends are inserted on the sliding sleeve 4 in " L " shape groove, and the positioning pin hole axis along overcoat fittings body 1 radially.When locating stud 8 was positioned at " L " shape groove transverse part outer end on the sliding sleeve 4, overcoat fittings body 1 was freed with interior plug joint 7, and when locating stud 8 was positioned at " L " shape groove upper end, overcoat fittings body 1 was connected with interior plug joint 7.
Working procedure of the present invention is, when needs rapid pipe joint disconnects, spur sliding sleeve 4 left on earth with hand, make locating stud 8 touch the translot of " L " shape groove, then rotate sliding sleeve 4, make locating stud 8 be positioned at the transverse part outer end of " L " shape groove, fix sliding sleeve 4 by the interaction force between the translot of locating stud 8 and " L " shape groove, this moment, overcoat fittings body 1 and Nei Sai joint 7 were all thrown off the constraint of ball 5, just can disconnect very easily.
When needs rapid pipe joint connects, overcoat fittings body 1 and 7 docking of Nei Sai joint, then rotate sliding sleeve 4, make locating stud 8 be positioned at transverse part the inner of " L " shape groove, this moment, sliding sleeve 4 automatically reset under the effect of spring 3, locating stud 8 is positioned at " L " shape groove upper end, by ball 6 overcoat fittings body 1 and Nei Sai joint 7 are located, thereby the overcoat fittings body 1 of hydraulic joint and Nei Sai joint 7 connects together.
Can know by said process, when rapid pipe joint is installed, because locating stud 8 will rotate sliding sleeve 4 and fix first, therefore only need both hands respectively overcoat fittings body 1 and 7 docking of Nei Sai fittings body at rapid pipe joint two ends to be put in place, rotate sliding sleeve 4 again and just can be in place, people is free-hand just can to finish.
