Description

Technical Field

[0001] The utility model relates to the technical field of grease connectors, in particular to a universal connector. Background Art

[0002] A grease gun connector (also known as a grease nipple, grease gun connector or grease injector connector) is an important component for connecting a grease gun and a grease nipple, and is used to inject the grease in the grease gun into the grease nipple of a mechanical device to provide necessary lubrication.

[0003] However, when the existing grease gun connector is in use, one end of it is directly connected to a grease hose, and the grease is transported into the grease gun connector through the grease hose, while the other end is connected to a grease nipple for oil injection. Therefore, the following technical problems exist in the use process: Since the grease gun connector is directly connected to the grease hose, and the grease gun connector needs to inject oil into different parts, the grease hose is easily entangled and knotted. Therefore, it is necessary to often untie the knots and straighten the grease hose to avoid the entanglement of the grease hose, resulting in great inconvenience in the entire oil injection process. Summary of the Invention

[0004] The main purpose of the utility model is to overcome the deficiencies in the prior art and provide a universal connector.

[0005] The technical solution adopted by the utility model to achieve its technical purpose is: A universal connector, the universal connector includes a grease gun connection component, a fixing component, a tubing connection component and a sealing connection component;

[0006] The sealing connection component is inserted into one end of the tubing connection component, one end of the tubing connection component and the sealing connection component are inserted into the inside of one end of the grease gun connection component, the fixing component passes through the tubing connection component and is threadedly connected to the outside of one end of the grease gun connection component. The sealing connection component and the tubing connection component are connected to one end of the grease gun connection component through the fixing component, and at the same time, the tubing connection component and the sealing connection component can rotate;

[0007] The injection tubing is threadedly connected through the tubing connection component, and then the grease gun is threadedly connected through the grease gun connection component.

[0008] Preferably, the sealing connection component is set as a rubber ring, and its outer wall is closely attached to the inner wall of one end of the grease gun connection component, so that the sealing connection component is hermetically connected to the inside of one end of the grease gun connection component.

[0009] Preferably, the tubing connection component includes a connection head, a retaining ring, a first convex tube and a second convex tube;

[0010] The retaining ring, the first convex tube and the second convex tube are fixedly connected to one end of the connector in sequence. The sealing connection component is sleeved on the second convex tube, and its outer circle is flush with the first convex tube, that is, the maximum diameter of the sealing connection component is the same as the diameter of the first convex tube.

[0011] The sealing connection component and the first convex tube are integrally inserted into the interior of one end of the oil gun connection component. The retaining ring is connected to the port of one end of the oil gun connection component, and the diameter of the retaining ring is slightly smaller than or equal to the diameter of the port of one end of the oil gun connection component.

[0012] Preferably, the oil gun connection component includes an internal thread sleeve and an external thread cylinder, and the fixing component is arranged as a nut sleeve.

[0013] After the fixing component passes through the connector, one end of it is threadedly connected to the external thread cylinder, and the other end presses the retaining ring against the port of one end of the oil gun connection component, and the connector can be rotated.

[0014] Since the sealing connection component and the first convex tube are integrally inserted into the interior of one end of the oil gun connection component, the sealing connection component and the first convex tube can rotate inside the interior of one end of the oil gun connection component. Then, the other end of the fixing component presses the retaining ring against the port of one end of the oil gun connection component to limit the position of the retaining ring, and at the same time, the rotation of the connector is maintained.

[0015] Preferably, the connector is arranged as an internal thread pipe fitting or a hollow screw rod. A clamping groove is provided at one end of the connector close to the retaining ring. The connector being arranged as an internal thread pipe fitting or a hollow screw rod facilitates connecting oil pipes with different heads, and the clamping groove facilitates clamping the connector to make it immovable, which is convenient for installing the oil pipe.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] This universal connector is connected to the grease gun through the connection component and the oil pipe connection component is connected to the grease hose. Then, through the cooperation of the fixing component and the sealing connection component, it can rotate 360 degrees forward and backward. The whole connection is arranged between the grease gun joint and the grease hose, so that the grease hose will never knot during use, effectively increasing the oil injection efficiency. Moreover, the connector in the oil pipe connection component can be an internal thread pipe fitting or a hollow screw rod, which can be used to connect oil pipes with different heads.
