Description

Technical Field

[0001] This utility model specifically relates to a gearbox oil supply connector with a clamping structure. Background Technology

[0002] The gearbox oil supply connector is an important component that connects the oil supply system to the gearbox. It introduces lubricating oil or hydraulic oil from the external oil supply system into the gearbox, providing lubrication and cooling for the gears, bearings and other components inside the gearbox. This reduces friction and wear between components, lowers the operating temperature, and extends the service life of the gearbox.

[0003] Currently, after the oil supply connector is connected to the gearbox oil supply port, it may show signs of falling off after a period of use due to the threaded connection alone, resulting in oil leakage and affecting the performance. Utility Model Content

The connector body is hollow and has an internal channel for oil flow. The oil supply pipeline connector and the gearbox oil supply port connector are respectively located at both ends of the channel. The clamping assembly is located on the gearbox oil supply port connector and is used to fix the gearbox oil supply port connector after connection.

[0006] Preferably, a locking nut is provided on the outside of the gearbox oil supply port connector, and the clamping assembly includes two limiting claws provided on the outside of the locking nut.

[0007] Preferably, the two limiting claws are symmetrically arranged, and the opposite sides of the limiting claws face the recess to form an arc-shaped groove.

[0011] Preferably, a connecting plate is provided on the outside of the locking nut, and the other end of the elastic element is connected to the connecting plate.

[0012] The technical effects and advantages of this utility model are as follows: The gearbox oil supply connector with a clamping structure connects the oil supply pipeline connector and the gearbox oil supply port connector to the oil supply pipeline and the gearbox oil supply port, respectively. By rotating the locking nut, the gearbox oil supply port connector is fixed. Under the elastic force of the elastic element, the limiting claw is pulled, so that the tooth groove of the limiting claw abuts against the outer circumference of the gearbox oil supply port, thereby clamping and fixing the connected gearbox oil supply port connector, improving the stability of the connected gearbox oil supply port connector and preventing it from falling off.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] To improve the stability of gearbox oil supply port connector 3 after installation, refer to... Figure 1 , Figure 2 and Figure 3As shown, the device includes a connector body 1, an oil supply line connector 2, a gearbox oil supply port connector 3, and a clamping assembly. The connector body 1 is hollow and has an internal channel 4 for oil flow. The oil supply line connector 2 and the gearbox oil supply port connector 3 are respectively located at both ends of the channel 4. The clamping assembly is located on the gearbox oil supply port connector 3 and is used to fix the connected gearbox oil supply port connector 3. The oil supply line connector 2 and the gearbox oil supply port connector 3 are connected to the oil supply line and the gearbox oil supply port, respectively. The locking nut 5 is rotated to fix the gearbox oil supply port connector 3. Under the elastic force of the elastic element 13, the limiting claw 6 is pulled so that the tooth groove 8 of the limiting claw 6 abuts against the outer circumference of the gearbox oil supply port, thereby clamping and fixing the connected gearbox oil supply port connector 3 and improving the stability of the connected gearbox oil supply port connector 3.

[0021] To further improve the clamping of the gearbox oil supply port connector 3, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a locking nut 5 is provided on the outer side of the gearbox oil supply port connector 3. The clamping assembly includes two limiting claws 6 located on the outer side of the locking nut 5. The locking nut 5 is used to first install the gearbox oil supply port connector 3, achieving initial fixation. The two limiting claws 6 are symmetrically arranged, and the opposite side of the limiting claws 6 faces the concave arc groove 7. The two limiting claws 6 clamp and fix the outer circumference of the oil supply port. The arc groove 7 adapts to the outer arc of the port end, improving clamping performance. The limiting claws 6 facing the arc groove 7 have wavy toothed grooves 8 at both ends of the arc groove 7. The toothed grooves 8 further increase the friction on the port end, completing the clamping and fixing of the limiting claws 6 and improving the fixation of the gearbox oil supply port connector 3 after connection. A connecting block 9 is provided on the outside of the locking nut 5, and a groove 10 is provided in the tail of the limiting claw 6. A rotating block 11 is connected to the groove 10 through a rotating shaft 15. The rotating block 11 is connected to the connecting block 9. When the gearbox oil supply port connector 3 is installed, the rotating shaft 15 rotates the rotating block 11, causing the clamping part of the limiting claw 6 to move away from the interface end. After the gearbox oil supply port connector 3 is installed, the rotating block 11 can rotate again, allowing the limiting claw 6 to abut against the interface end. A fixed seat 12 is provided at the end of the groove 10 away from the rotating block 11. An elastic element 13 is provided on the outside of the fixed seat 12. When the fixing of the limiting claw 6 is released, the elastic element 13 deforms, and the elastic force acts on the limiting claw 6, pulling the clamping part of the limiting claw 6 towards the interface end, so that the arc groove 7 abuts against the outside of the interface end. The outside of the interface end of the gearbox oil supply port connector 3 is arc-shaped and matches the arc groove 7. A connecting plate 14 is also provided on the outside of the locking nut 5. The other end of the elastic element 13 is connected to the connecting plate 14. The elastic element 13 is installed through the connecting plate 14. The elastic element 13 can be a return spring or a tension spring.

[0022] In use, first connect the oil supply line connector 2 and the gearbox oil supply port connector 3 to the oil supply line and the gearbox oil supply port respectively. Rotate the locking nut 5 to fix the gearbox oil supply port connector 3. Under the elastic force of the elastic element 13, pull the limiting claw 6 so that the tooth groove 8 of the limiting claw 6 abuts against the outer circumference of the gearbox oil supply port, thus clamping and fixing the connected gearbox oil supply port connector 3.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
