Abstract
Description
Technical Field
[0001] The utility model relates to a pipe joint, in particular to an oil delivery joint and a universal oil delivery joint. Background Art
[0002] The existing conveying joint has a relatively simple structure. A movable joint is usually provided in the conveying joint. The joint extends upward from the conveying joint and is connected to an external device. When oil is not passed into the conveying joint, the joint can rotate in the conveying joint, thereby providing rotational freedom between the conveying joint and the device, and keeping the conveying joint and the device connected to each other. When oil is passed into the conveying joint, the oil pressure in the conveying joint is high, which will squeeze the joint into the conveying joint. At this time, it is easy to cause the joint to be unable to turn or difficult to turn, affecting the normal use of the conveying joint. Utility Model Content
[0003] The utility model aims to provide an oil delivery joint and a universal oil delivery joint to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.
[0004] The solution of the utility model to solve the technical problem is:
[0005] An oil delivery joint comprises: an oil delivery seat, one side of which is provided with a mounting groove, and the other side is provided with a connecting groove, the oil delivery seat is provided with a connecting flow channel connected to the mounting groove and the connecting groove; a connector, one end of which is inserted into the mounting groove and connected to the connecting flow channel, a limit shoulder is provided at the position of the connector in the mounting groove, and a feed flow channel is provided in the connector along its length direction; a bearing, which is sleeved into the top of the connector; a pressure cover, which is sleeved on the outer side of the top of the connector, the pressure cover is connected to the top of the oil delivery seat, and the pressure cover presses the bearing against the limit shoulder.
[0006] This technical solution has at least the following beneficial effects: the connecting groove on one side of the oil delivery seat can be used to connect the feeding equipment of the external device, and the installation groove on one side can be used to connect the receiving equipment of the external device. When in use, the feeding equipment delivers materials into the oil delivery seat, inputs the materials into the feeding channel through the connecting channel, and finally flows into the receiving equipment. Since the pressure cover presses the bearing onto the limiting shoulder, the connecting head can keep its end connected to the connecting channel, and the pressure in the connecting channel is relatively high, so the connecting head is pushed against the pressure cover. When the feeding equipment and the receiving equipment rotate relative to each other during the feeding process, the bearing can be used to greatly reduce the friction between the limiting shoulder and the pressure cover, so that the connecting head can rotate smoothly in the oil delivery seat. In this way, the oil delivery joint can be used to maintain stable material feeding and ensure smooth rotation during the feeding process, which is highly practical.
[0007] As a further improvement of the above technical solution, a first gasket is sleeved on the outer side of the top of the connector, and the first gasket is located between the gland and the bearing. The gland is pressed against the top side of the bearing through the first gasket, and the first gasket can be in close contact with the top side of the bearing, thereby improving the stability of the connector rotation. In addition, the first gasket can also be used to reduce and buffer the friction between the gland and the bearing when it is fixed to the top side of the oil delivery seat, so that the gland connection is more secure.
[0008] As a further improvement of the above technical solution, a second gasket is sleeved on the outer side of the top of the connector, and the second gasket is located between the bearing and the limiting shoulder. Similarly, the bearing is pressed against the top side of the limiting shoulder through the second gasket, and the second gasket can be in close contact with the bottom side of the bearing, thereby improving the stability of the connector rotation.
[0009] As a further improvement of the above technical solution, a sealing groove is provided at the bottom of the installation groove, one end of the connecting flow channel extends to the bottom of the sealing groove, and a sealing ring is sleeved at the bottom of the connector located outside the sealing groove. The sealing groove can enhance the connection sealing between the connector and the connecting flow channel, and the sealing groove is used to accommodate the sealing ring, which can effectively reduce the oil from entering the installation groove from the assembly gap between the connector and the connecting flow channel.
[0010] As a further improvement of the above technical solution, the connector is provided with an external thread at an outer position above the gland, so that the connector can be directly connected to the structure of the external device through the external thread, which is more convenient to use.
[0011] As a further improvement of the above technical solution, a connecting section is provided on the outer side of the bottom end of the connector, and the outer diameter of the connecting section gradually decreases downward, and the connecting section abuts against the top of the connecting flow channel. Since the outer diameter of the connecting section gradually decreases downward, the connecting section forms a structure that is larger at the top and smaller at the bottom. When the connector is inserted into the installation groove, the gradually narrowing connecting section can be more easily inserted into the connecting flow channel, and the connector can be limited, so that the connector is more stable when rotating.
[0012] As a further improvement of the above technical solution, the gland is connected to the outer side of the top of the oil delivery seat by threads. The gland is fixed to the top side of the oil delivery seat by threads, so that the connection between the gland and the oil delivery seat is convenient and stable.
[0013] A universal oil delivery joint comprises the above-mentioned oil delivery connector, wherein the connecting groove is located on a side of the oil delivery seat adjacent to the mounting groove, and the connecting head of one oil delivery connector is connected to the connecting groove of another oil delivery connector.
[0014] This technical solution has at least the following beneficial effects: after the two oil transfer connectors are connected to each other, they form a universal oil transfer joint with two degrees of rotational freedom. At this time, the rotation axes of the two oil transfer connectors are vertical at 90 degrees. The vacant connecting head can be used to connect the external material receiving equipment, and the vacant mounting groove can be used to connect the external material feeding equipment. In this way, the stability of the connection between the feeding equipment and the material receiving equipment can be better maintained.
[0015] As a further improvement of the above technical solution, a transfer head is connected in the connection groove of another oil delivery joint. The vacant installation groove is connected to the transfer head, and the peripheral feeding equipment can be connected through the transfer head, which improves the versatility of connection.

[0021] In this oil delivery joint, the connecting groove on one side of the oil delivery seat 100 can be used to connect the feeding equipment of the external device, and the installation groove on one side can be used to connect the receiving equipment of the external device. When in use, the feeding equipment feeds the material into the oil delivery seat 100, inputs the material into the feeding channel 210 through the connecting channel 110, and finally flows into the receiving equipment. Since the pressure cover 400 presses the bearing 300 against the limiting shoulder 220, the connecting head 200 can keep its end connected to the connecting channel 110, and the pressure in the connecting channel 110 is relatively high, so the connecting head 200 is pushed against the pressure cover 400. When the feeding equipment and the receiving equipment rotate relative to each other during the feeding process, the bearing 300 can be used to greatly reduce the friction between the limiting shoulder 220 and the pressure cover 400, so that the connecting head 200 can rotate smoothly in the oil delivery seat 100. In this way, the oil delivery joint can be used to maintain stable material feeding and ensure smooth rotation during the feeding process, which is highly practical.
[0022] In order to more stably press against the top side of the bearing 300, in this embodiment, a first gasket 310 is sleeved on the outer side of the top of the connector 200, and the first gasket 310 is located between the gland 400 and the bearing 300. The gland 400 is pressed against the top side of the bearing 300 through the first gasket 310, and the first gasket 310 can be in close contact with the top side of the bearing 300, thereby improving the stability of the rotation of the connector 200. In addition, the first gasket 310 can also be used to reduce and buffer the friction between the gland 400 and the bearing 300 when it is fixed to the top side of the oil delivery seat 100, so that the gland 400 is more firmly connected.
[0023] In the above embodiment, the limiting shoulder 220 can be directly used to abut against the bottom side of the bearing 300, while in this embodiment, a second gasket 320 is sleeved on the outer side of the top of the connector 200, and the second gasket 320 is located between the bearing 300 and the limiting shoulder 220. Similarly, the bearing 300 is pressed against the top side of the limiting shoulder 220 through the second gasket 320, and the second gasket 320 can be in close contact with the bottom side of the bearing 300, thereby improving the stability of the rotation of the connector 200.
[0024] By pressing the bottom end of the connector 200 against the position of the bottom of the installation groove at the top of the connecting flow channel 110, the feed flow channel 210 and the connecting flow channel 110 can be kept connected and conducted with each other. In order to reduce the leakage of oil from the gap between the bottom end of the connector 200 and the installation groove into the installation groove, in this embodiment, a sealing groove is provided at the bottom of the installation groove, one end of the connecting flow channel 110 extends to the bottom of the sealing groove, and a sealing ring 230 is sleeved at the bottom of the connector 200 located outside the sealing groove. In practical applications, there can be multiple sealing rings 230, for example, two are arranged in the vertical direction in the installation groove. The sealing groove can enhance the connection sealing between the connector 200 and the connecting flow channel 110, and the sealing groove is used to accommodate the sealing ring 230, which can effectively reduce the oil from the assembly gap between the connector 200 and the connecting flow channel 110.

[0026] In order to better limit the bottom end of the connector 200, in this embodiment, a connecting section is provided on the outside of the bottom end of the connector 200, and the outer diameter of the connecting section gradually decreases downward, and the connecting section abuts against the top of the connecting flow channel 110. Since the outer diameter of the connecting section gradually decreases downward, the connecting section forms a structure that is larger at the top and smaller at the bottom. When the connector 200 is inserted into the installation slot, the gradually narrowing connecting section can be more easily inserted into the connecting flow channel 110, and the connector 200 can be limited, so that the connector 200 is more stable when rotating.
[0027] In the above embodiment, the pressure cover 400 can be fixed to the outer side of the top of the oil delivery seat 100 by means of buckles, etc., while in this embodiment, the pressure cover 400 is connected to the outer side of the top of the oil delivery seat 100 by threads. The pressure cover 400 is fixed to the top side of the oil delivery seat 100 by threaded connection, so that the connection between the pressure cover 400 and the oil delivery seat 100 is convenient and stable.
