Abstract
The utility model provides a self-sealing hydraulic quick shift joint comprising a yang joint with a thread interface and a first cavity, a yin joint with a thread interface, a second cavity and a third cavity used to accept the yang joint. A snap spring, a spring seat, a spring, a seal element are respectively arranged in sequence in the first cavity and the second cavity. The spring seals the seal element and the front end inner wall of the corresponding cavity. A steel sleeve is sleeved on the yin joint. A limit spring is arranged between the inner wall of the steel sleeve and the outer wall of the yin joint. A snap groove is arranged on the front outer wall of the yin joint. A snap spring is arranged in the snap groove. The yin joint is opened with rolling ball hole along the radial. A rolling ball is installed in the rolling ball hole. A groove which matches the rolling ball is arranged on the outer wall of the yang joint. The seal element is a steel ball. The utility model adopts the steel ball as the seal element, thus possessing a good seal effect, a good anti-aging performance and a good impact performance.

(2) background technique
Current hydraulic pressure quick release coupling generally comprises the male connector with threaded coupling and first cavity, has threaded coupling, second cavity and is used to hold the negative joint of the 3rd cavity of male connector; Jump ring, spring seat, spring, first Sealing are installed in described first cavity successively, and described spring makes the front inner wall sealing of first Sealing and first cavity; Jump ring, spring seat, spring, second Sealing are installed in described second cavity successively, and described spring makes second Sealing and the sealing of the second cavity front inner wall; Described negative joint is socketed with steel bushing, between described steel bushing inwall and the negative joint outer wall limit spring is installed, and negative joint front end outer wall is provided with draw-in groove, and jump ring is installed in the draw-in groove; Described negative joint radially has ball hole, in the described ball hole ball is installed, and described male connector outer wall is provided with the groove that matches with ball.During installation, press steel bushing downwards, male connector is inserted the 3rd cavity, ball falls in the groove of male connector, loosens steel bushing, and steel bushing upwards compresses ball makes male connector be fixed in the 3rd cavity.The head of first Sealing and the head of second Sealing offset at this moment, and first cavity of male connector is communicated with second cavity of negative joint.When male connector separates with negative joint, press steel bushing downwards, male connector is transferred to the 3rd cavity, the head of first Sealing no longer contacts with the head of second Sealing, this moment, spring made Sealing and cavity front inner wall seal respectively, thereby up to the purpose of quick switching.But existing first Sealing and second Sealing mostly are taper, and its sealing effect is relatively poor, its general rubber material that adopts in addition, and ageing-resistant performance, shock resistance are poor.
(3) model utility content
The purpose of this utility model is to provide a kind of good sealing effect, nonabradable self sealing hydraulic pressure quick release coupling.
Described self sealing hydraulic pressure quick release coupling comprises the male connector with threaded coupling and first cavity, has threaded coupling, second cavity and is used to hold the negative joint of the 3rd cavity of male connector;
Jump ring, spring seat, spring, Sealing are installed respectively in described first cavity and second cavity successively, and described spring makes Sealing seal with the front inner wall of corresponding cavity;
Described negative joint is socketed with steel bushing, between described steel bushing inwall and the negative joint outer wall limit spring is installed, and negative joint front end outer wall is provided with draw-in groove, and jump ring is installed in the draw-in groove;
Described negative joint radially has ball hole, in the described ball hole ball is installed, and described male connector outer wall is provided with the groove that matches with ball;
Described Sealing is a steel ball.
Male connector and negative joint are communicated with outside oil circuit by threaded coupling respectively during use.
The size of screw thread is preferably as follows in male connector of the present utility model and the negative joint: NPT1/2,22 * 1.5,20 * 1.5,18 * 1.5.
Sealing in the utility model adopts steel ball, its good sealing effect, and ageing-resistant performance and shock resistance are good.
(4) description of drawings
Fig. 1 is the sectional drawing of described male connector.
Fig. 2 is the sectional drawing of described negative joint.
(5) embodiment
The utility model is described in further detail below in conjunction with embodiment, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, a kind of hydraulic pressure quick release coupling comprises the male connector 3 with threaded coupling 1 and first cavity 2, has threaded coupling 4, second cavity 5 and is used to hold the negative joint 7 of the 3rd cavity 6 of male connector 3; 2 install jump ring 8, spring seat 9, spring 10, first Sealing 11 successively in described first cavity, and described spring 10 makes the front inner wall sealing of first Sealing 11 and first cavity 2; Jump ring 12, spring seat 13, spring 14, second Sealing 15 are installed in described second cavity 5 successively, and described spring 14 makes the front inner wall sealing of second Sealing 15 and second cavity 5; Described negative joint 7 is socketed with steel bushing 16, between described steel bushing 16 inwalls and negative joint 7 outer walls limit spring 17 is installed, and negative joint 7 front end outer walls are provided with draw-in groove, and jump ring 18 is installed in the draw-in groove; Described negative joint 7 radially has ball hole, and ball 19 is installed in the described ball hole, and described male connector 3 outer walls are provided with the groove 20 that matches with ball 19;
Described first Sealing 11 and second Sealing 15 are steel ball.
During installation, press steel bushing 16 downwards, male connector 3 is inserted the 3rd cavity 6, ball 19 falls in the groove 20 of male connector 3, loosens steel bushing 16, and limit spring .17 makes steel bushing 16 upwards compress ball 19 to make male connector 3 be fixed in the 3rd cavity 6.This moment, head and the head of second Sealing 15 of first Sealing 11 offseted, and both move a segment distance after respectively, thereby first cavity 2 of male connector 3 is communicated with second cavity 5 of negative joint 7, thus two outside oil circuits connections.When male connector 3 separates with negative joint 7, press steel bushing 16 downwards, male connector 3 is transferred to the 3rd cavity 6, the head of the head of first Sealing 11 and second Sealing 15 no longer compresses, this moment, spring 10 compressed first Sealing 11, made the front inner wall sealing of first Sealing 11 and first cavity 2, and spring 14 compresses second Sealing 15, make the sealing of second Sealing 15 and second cavity, 5 front inner wall, thereby up to the purpose of quick switching.
