Description

Technical Field

[0001] This utility model relates to the field of oil circuit connection technology, specifically a high-pressure oil circuit quick connector. Background Technology

[0002] In modern industrial applications, high-pressure hydraulic systems are widely used in various mechanical equipment, especially in hydraulic transmission, lubrication systems, and high-pressure fuel injection. These systems typically require hydraulic connection components to withstand extremely high pressures, while also possessing fast, safe, and reliable connection characteristics to ensure efficient equipment operation and personnel safety. High-pressure hydraulic quick couplings have emerged as an indispensable component in high-pressure hydraulic systems, enabling rapid connection and disconnection of hydraulic pipelines in a short time, greatly facilitating equipment installation, maintenance, and replacement.

[0003] In the existing technology, the high-pressure oil circuit quick coupling uses a lever to open and close the pipeline at the coupling end. However, the lever as a whole may break or be damaged by impact and use, affecting its use. Furthermore, in the use of high-pressure oil circuits, accidental contact at the upper quick coupling end can cause the coupling cap to move, which may lead to detachment and create a safety hazard.

[0004] Therefore, a high-pressure oil circuit quick connector is needed to improve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-pressure oil circuit quick connector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-pressure oil circuit quick connector includes a main body, with threaded connectors and quick connector parts connected to both ends of the main body, a connector cap on the outer side of the main body, a ball valve inside the quick connector part, and a rotatable actuating element on one side of the quick connector part. The actuating element mates with the ball valve. A convex ring is fixedly connected to the end of the connector cap. When the actuating element drives the ball valve to the open state, the protrusions on both sides of the actuating element maintain contact and limit the movement with the convex ring.

[0008] As a preferred embodiment of this utility model, the actuating component includes a handle, with a set of symmetrically arranged handle side protrusions connected at a height on both sides of the handle, and a connecting shaft fixedly connected to the middle of the handle by screws, the connecting shaft passing through the quick connector and fixedly connected to the ball valve.

[0009] As a preferred embodiment of this utility model, when the ball valve is in the open state, the outer side of the convex strip on the handle abuts against the end of the convex ring to keep the handle in a stable and limited position.

[0010] As a preferred embodiment of this utility model, the quick connector portion is a connector end.

[0011] As a preferred embodiment of this utility model, the connector cap is elastically connected to the outer side of the main body through an elastic element, and the connector cap can move elastically up and down relative to the main body.

[0012] As a preferred embodiment of this utility model, the end of the connector is provided with a three-pin structure for quick connection.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model adopts a handle-type valve opening component. When the internal ball valve is open, the convex strip on the handle side abuts against the convex ring end of the connector cap, so that the handle remains stably limited. Compared with the prior art, it avoids the situation of being impacted or broken during use. At the same time, it can prevent the connector cap from moving and detaching due to accidental contact at the quick connector end when used in high-pressure oil circuits. Attached Figure Description

[0023] Please see Figure 1-3 This utility model provides a technical solution:

[0024] For an example, please refer to... Figure 1 , 2 3. A high-pressure oil circuit quick connector includes a main body, with threaded connectors 6 and quick connector parts connected to both ends of the main body respectively. A connector cap 2 is provided on the outer side of the main body. A ball valve 7 is provided inside the quick connector part. A rotatable actuating element is provided on one side of the quick connector part. The actuating element mates with the ball valve 7. A convex ring 5 is fixedly connected to the end of the connector cap 2. When the actuating element drives the ball valve 7 to the open state, the convex parts on both sides of the actuating element maintain abutment and limit with the convex ring 5. The connector cap 2 is elastically connected to the outer side of the main body through an elastic element. The connector cap 2 can move up and down elastically relative to the main body. The elastic element is a spring.

[0025] A rotatable actuating element is adopted. By rotating the actuating element, the operating state of the ball valve 7 can be changed. When the ball valve 7 is in the open state, the protrusion on the outer side of the actuating element and the convex ring 5 are kept in contact and limited, so as to maintain the overall stability of the actuating element and avoid the occurrence of impact or breakage during use. At the same time, it can also prevent the quick-connect end from accidentally touching and causing the connector cap to move and detach when used in high-pressure oil circuit.

[0026] Please refer to Figure 1 , 2 3. The actuating component includes a handle 3. A set of symmetrically arranged handle side protrusions 4 are connected to both sides of the handle 3. A connecting shaft 8 is fixedly connected to the middle of the handle 3 by screws. The connecting shaft 8 passes through the quick connector and is fixedly connected to the ball valve 7. When the ball valve 7 is in the open state, the outer side of the handle side protrusion 4 abuts against the end of the convex ring 5 to keep the handle 3 in a stable position.

[0027] The handle 3 is connected to the connecting shaft 8 by screws. By rotating the handle 3, the connecting shaft 8 and the ball valve 7 are driven to change their state. In the open state, the convex strip 4 on the side of the handle and the convex ring 5 are kept in contact, thereby keeping the handle 3 in a stable position and preventing it from breaking due to impact or use.

[0028] Please refer to Figure 1 , 2 3. The quick connector part is connector end 1. The interior of connector end 1 is provided with a three-pin structure for quick connection. The three-pin structure is a common quick connector structure used in the prior art, which is not shown in the figure. Using this structure, quick connection of connector end 1 can be achieved.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
