Description

TECHNICAL FIELD

[0001] The utility model relates to butter connector technical field, concretely is a tee butter injection port structure. BACKGROUND

[0002] In the mechanical lubrication system, the butter connector is a kind of connecting device for distributing and injecting lubricating grease (butter). This structure is usually composed of three interconnected channels, and the operator can conveniently inject butter into the tee connector, and then distribute it to each lubrication point of the equipment by the connector.

[0003] In the prior art, before injecting butter into the tee butter connector, the butter gun needs to be butt-jointed with the injection port of the tee butter connector. In the specific operation process, the operator needs to align the oil injection pipe of the butter gun with the oil injection port of the tee connector, to ensure that the two are in close contact and avoid leakage of lubricating grease. Then, the butter gun is operated manually or electrically to inject butter into the tee connector. After injection is completed, the butter flows to the lubrication point of the equipment through the distribution channel of the tee connector.

[0004] However, since the oil injection port of the tee butter connector is usually designed to be small and delicate, the operator may fail to accurately butt-joint the oil injection port due to the shaking or improper operation of the butter gun during oil injection. This inaccurate butt-jointing not only leads to waste of lubricating grease, but also requires the operator to repeatedly adjust the position of the butter gun and perform butt-jointing operation again, thereby significantly reducing the oil injection efficiency. In addition, if the oil injection port is designed unreasonably, it may increase the difficulty of the operator's work, especially in a small space or when the equipment is located at a high position, the operator's oil injection operation will be more inconvenient, further affecting the oil injection efficiency and the convenience of equipment maintenance.

[0025] Connecting block 6 is fixedly connected with limit sleeve 5, limit sleeve 5 is fixedly connected with oil injection pipe 3, so that connecting block 6 is fixed on one side of butter gun 4, when three-way connector 1 and oil injection pipe 3 are needed to butt joint, limit sleeve 5 and butt joint pipe 2 are slidably connected, so that limit sleeve 5 is set on the outer circle surface of butt joint pipe 2, and the oil outlet of butt joint pipe 2 and oil injection pipe 3 is abutted, in order to not occur deflection between butt joint pipe 2 and oil injection pipe 3 in the process of injection, i.e. the butt joint of oil injection pipe 3 and the input end of three-way connector 1 is accurate, by rotating eccentric column 7, the big circle end of eccentric column 7 is rotated to the direction of approaching arc convex block 8, so as to extrude arc convex block 8 to move to the direction of approaching arc concave surface 17, since arc convex block 8 is symmetrically arranged about butt joint pipe 2, then the arc convex block 8 on both sides simultaneously extrudes the arc concave surface 17 on the both sides of the outer circle surface of butt joint pipe 2, and then butt joint pipe 2 is fixed in limit sleeve 5, so as to guarantee the real-time accurate butt joint of butt joint pipe 2 and oil injection pipe 3 in the process of injection, to avoid butter waste.

[0026] In the embodiment two, the two output ends of the three-way connector 1 are sleeved with the connecting sleeve 9, and are threadedly connected with the connecting sleeve 9, so as to facilitate the disassembly between the connecting sleeve 9 and the output end of the three-way connector 1. The inside of the connecting sleeve 9 is fixedly connected with the filter plate 10. The filter plate 10 is provided with the sealing ring 11 on one side. The filter plate 10 installed in the inside of the connecting sleeve 9 can filter the impurities in the butter, so as to avoid the impurities entering the equipment. Meanwhile, the impurities on the filter plate 10 can be removed by disassembling the connecting sleeve 9. The sealing ring 11 is fixedly connected with the inner ring surface of the connecting sleeve 9.

In order to prevent the connecting pipe 2 from being deviated from the oil injection pipe 3 during the oil injection process, that is, to ensure the accurate connection between the oil injection pipe 3 and the input end of the three-way connector 1, the eccentric column 7 is rotated by pulling the knob 13, so that the large circular end of the eccentric column 7 is rotated towards the arc convex block 8. During the process, the arc convex block 8 is pressed to gradually abut against the arc concave surface 17 formed on the outer ring surface of the connecting pipe 2, and the arc convex block 8 pulls the spring 15 under the connection of the limiting rod 16. The spring 15 is stretched, and the contact area between the arc convex block 8 and the arc concave surface 17 gradually increases with the increase of the rotation angle. When the eccentric column 7 is rotated to a specific angle, the large circular end of the arc convex block 8 completely abuts against the arc concave surface 17, so that the rotation of the eccentric column 7 is prevented, the limiting function of the connecting pipe 2 is realized, and the accurate connection between the input end of the three-way connector 1 and the oil injection pipe 3 is completed, thereby ensuring the stability during the oil injection process. When the oil injection is completed, the limiting between the arc concave surface 17 and the eccentric column 7 is released by pulling the knob 13 in the opposite direction, so that the spring 15 pulls the limiting rod 16 under the action of the reverse elastic force of the spring 15, the limiting rod 16 pulls the arc convex block 8 to move, the arc convex block 8 is no longer pressed against the arc concave surface 17, the limiting between the limiting sleeve 5 and the three-way connector 1 is released, and then the grease gun 4 can be removed. Finally, the three-way connector 1 on the oil nozzle is pulled out, and the oil injection process is completed.
