Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Reference Figure 1 and Figure 2The multi-locking leak-proof high-pressure connector shown includes a claw 1. Its features include: a latching assembly 2 fixedly mounted on the lower surface of the claw 1; the claw 1 being latched to a main body 3 via the latching assembly 2; a connector head 4 fixedly mounted on the lower surface of the main body 3; a threaded ring 5 and a ball bearing assembly 6 on the surface of the connector head 4; a locking assembly 7 fixedly mounted on the side of the main body 3; a first waterproof ring 8 on the upper surface of the claw 1; a second waterproof ring 9 on the lower surface of the connector head 4; and a claw spring 10 fixedly mounted on the lower surface of the claw 1, through which the claw 1 is fixedly connected to the main body 3. The inner bottom wall of the connector head 4 is connected through the hole of the claw 1 and then screwed on by the ball assembly 6. The ball set in the ball assembly 6 will lock the groove opened on the connector head 4, thereby achieving initial locking. When the connector head 4 is fully inserted into the claw 1, the first waterproof ring 8 will wrap around the tail end of the connector head 4 to achieve the sealing and leakage prevention of the interface. The second waterproof ring 9 is set on the lower surface of the connector head 4, thereby contacting the water outlet inside the connector to achieve the sealing and leakage prevention during flow. The buckle assembly 2 and the locking assembly 7 further lock the connector after the connector head 4 is connected in sequence.

[0024] As a preferred embodiment of this example, Figure 1 and Figure 3As shown, the buckle assembly 2 includes a fastener 201. A groove is formed on the surface of the fastener 201, and a buckle 202 is fastened inside the groove. A first spring 203 is fixedly installed on the lower surface of the buckle 202, and a first spring 204 is fixedly installed on the lower surface of the first spring 203. A component groove is formed on the upper surface of the main body 3. The lower surface of the first spring 204 is fixedly installed in the component groove. A second spring 205 is fixedly installed on the inner bottom wall of the component groove, and a second spring 206 is fixedly installed on the upper surface of the second spring 205. A release element 207 is provided on the upper surface of the buckle 202. Holes are formed on both sides of the buckle 202, and a first fixing element 208 is fixedly installed inside the holes. The bottom of the first fixing element 208 is fixedly installed on the inner bottom wall of the component groove. A pressing element 209 is fixedly installed on the upper surface of the release element 207, and holes are formed on both sides of the pressing element 209, with a second fixing element 206 fixedly installed inside the holes. 10. A pressing piece 211 is fixedly installed at one end of the pressing member 209. A claw spring 10 is provided on the lower surface of the claw 1. Therefore, when the head of the connector 4 is gradually inserted into the claw 1, the claw 1 also inserts downwards. When the claw 1 inserts downwards, the fastening member 201 provided on it is pressed downwards. When the fastening member 201 is pressed down to a certain position, the end of the fastening member 202 is engaged in the groove of the fastening member 201. The second spring 205 and the second spring member 206 are fastened together. The fastening of the connector 201 provides elastic deformation support. When it is necessary to release the buckle assembly 2, the pressing plate 211 is oscillated upwards. The pressing member 209 connected to the pressing plate 211 will apply downward pressure under the rotation constraint of the second fixing member 210, pressing down the release member 207. After the release member 207 is pressed down, it drives the buckle member 202, causing the buckle member 202 to tilt up under the rotation constraint of the first fixing member 208, so that the fastening member 201 is released from the fastening constraint of the buckle member 202.

[0025] like Figure 1 and Figure 4 As shown, in this embodiment, the ball assembly 6 includes a ball 601. The surface of the ball 601 is provided with an extrusion member 602. One end of the extrusion member 602 is fixedly installed with a locking member 603. The inner wall of the locking member 603 is provided with a threaded hole. The threaded hole is compatible with the threaded ring provided at the head of the connector 4. When the head of the connector 4 is threaded into the locking member 603, the locking member 603 drives the extrusion member 602 to slowly press upward, pressing the ball 601 into the groove on the head of the connector 4, thereby locking it. The inside of the claw 1 is provided with an independent space to limit the movement of the ball 601.

[0026] like Figure 1 and Figure 5As shown, in this embodiment, the locking assembly 7 includes a third fixing member 701. Holes are formed on both sides of the third fixing member 701, and a rotating rod is inserted into the hole. A locking rod 702 is fixedly mounted on the surface of the rotating rod. A locking rod hole is formed inside the locking rod 702, and a first support member 703 is fixedly mounted inside the locking rod hole. Push rod holes are formed on both sides of the first support member 703, and a push rod 704 is inserted into the push rod hole. A push rod head 705 is fixedly mounted on one end of the push rod 704, and a first push rod head 705 is fixedly mounted on one side of the push rod head 705. A first push rod spring 706 has a push rod component 707 fixedly installed at one end, and a first push rod fixing component fixedly installed at one end of the push rod component 707. A second push rod spring 708 is fixedly installed at one end of the locking rod hole, and a second push rod fixing component is fixedly installed at one end of the second push rod spring 708. A pressure rod 709 is provided on the upper surface of the push rod 704. A second support component 710 is fixedly installed on the surface of the pressure rod 709. A pressure rod spring 711 is fixedly installed on the lower surface of the second support component 710. The inside of the pressure rod spring 711 is sleeved with the pressure rod 704. 09. One end of the pressure spring 711 is fixedly mounted with a pressure block 712. One side of the pressure block 712 is fixedly mounted on the main body 3. After the connector head 4 and the buckle assembly 2 are locked, the locking assembly 7 is activated, the locking rod 702 is aligned and pushed forward using the third fixing member 701. The push rod head 705 moves forward and contacts the pressure rod 709. The bottom end of the pressure rod 709 is at a bevel angle. Due to the deformation and rebound of the pressure spring 711, it will slide into the middle between the push rod head 705 and the push rod member 707 under the push of the push rod head 705. Then, due to the bevel angle... The push rod head 705 and the push rod member 707 are locked together. When the lock needs to be released, one end of the push rod 704 is pushed. The first push rod fixing member and the second push rod fixing member and the second push rod spring 708 will push the push rod member 707 forward to move closer to the push rod head 705. The surface of the push rod head 705 is also beveled, which will squeeze out the pressure rod 709, thereby releasing the lock. The first push rod spring 706, the second push rod spring 708 and the pressure rod spring 711 are configured to provide elastic deformation recovery force for the telescopic push lock function of the device.

[0027] The working principle of this practical technical solution is as follows:

[0028] In summary, when using the Honda locking leak-proof high-pressure connector, after screwing the connector head into the claw, the ball bearing assembly and the snap fastener assembly inside the connector will automatically lock. Finally, the locking assembly is used for the third locking process.
