Description

Technical Field

[0001] This utility model relates to the field of coupling lubrication technology, specifically to a coupling grease filling device. Background Technology

[0002] Couplings, also known as couplings or back-to-back wheels, are devices used in mechanical engineering to connect two shafts or a shaft and a rotating component and transmit motion and torque. They have functions such as compensating for misalignment, buffering and damping vibration, and overload protection. During the use of couplings, grease is required. Currently, existing grease filling devices do not have a quick-release mechanism, making them difficult to disassemble for internal cleaning. Furthermore, the grease filling mechanism itself inevitably requires cleaning and maintenance, making current filling devices inconvenient to use.

[0003] A search revealed an electric grease gun with publication number CN212080820U, comprising a barrel, one end of which is fixedly connected to a nozzle connector, a first one-way valve fixedly installed inside the nozzle connector, a refill tube fixedly connected through the lower surface of the barrel near the nozzle connector, a receiving seat fixedly connected to the outer surface of the refill tube, and an oil storage tank rotatably connected to the outer surface of the receiving seat via a threaded connection. This technical solution also suffers from the aforementioned technical problems. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 A coupling grease filling device includes a cylindrical housing 1 with an open left side and a housing 4 with an open right side on its left side. A discharge pipe 8 is connected to the left side of housing 4. The discharge pipe 8 is used to discharge grease from housings 1 and 4. A valve is installed on the discharge pipe 8 to open and close it. A fixed ring 2 is fixedly connected to the side of housing 1. A threaded ring 3 with threads on its surface is fixedly connected to the side of the fixed ring 2. A connecting ring 5 is threadedly connected to the surface of the threaded ring 3. The connecting ring 5 is fixedly welded to the surface of housing 4. The housings 1 and 4 are connected by a threaded connection, resulting in a stable connection and easy operation.

[0017] To ensure a tight seal between housing 1 and housing 4, an annular mating ring 9 is welded to the opening on the side of housing 1, and an annular mating ring 11 is welded to the opening on the right side of housing 4. The mating rings 9 and 11 are the same size. An annular groove 10 is formed on the left side of mating ring 9, while a sealing ring 12 is fixedly bonded to the right side of mating ring 11. In actual use, the sealing ring 12 is slightly larger than the annular groove 10, and it is inserted into the groove with a tight seal. The sealing ring 12 is made of rubber. This design provides a good seal. In the accompanying drawings, the sealing ring 12 is smaller than the annular groove 10 for visual clarity. The threaded connection between housing 1 and housing 4 ensures a stable and tight fit between the sealing ring 12 and the annular groove 10. An injection pipe 6 is fixedly connected to the top of housing 4, extending beyond the housing. An injection cap 7 is threadedly connected to the top of the injection pipe 6. Figure 3 It is evident that rotating the injection cap 7 allows it to detach from the injection tube 6, after which grease can be squeezed into housing 1 and housing 4.

[0018] A threaded post 13 is threaded onto the housing 1. A piston 14 is fixedly connected to one end of the threaded post 13 inside the housing 1. When the threaded post 13 rotates, it moves on the housing 1, causing the piston 14 to move as well. The piston 14 can squeeze the grease inside the housing 1 and housing 4. An insert block 16 is fixedly connected to the other end of the threaded post 13 outside the housing 1. The insert block 16 is a rectangular block with a vertical cross-section, and a rotating block 15 is movably fitted onto its surface. This arrangement of the insert block 16 allows the operator to... The force exerted by the rotating block 15 can be transmitted to the threaded column 13. Two limiting ports 17 are provided on the rotating block 15. A telescopic rod 20 is fixedly connected to the inner wall of each limiting port 17. One end of the telescopic rod 20 is fixedly connected to a limiting plate 18. The side of the limiting plate 18 contacts the inner wall of the limiting port 17. The telescopic rod 20 prevents the limiting plate 18 from detaching from the limiting port 17 without affecting its movement within the port 17. The side of the limiting plate 18 facing the threaded column 13 extends beyond the limiting port 17, while the other side does not. The limit plate 18 extends beyond the limit opening 17 to facilitate operator operation. A limit rod 19 is fixedly connected to the side of the limit plate 18 furthest from the telescopic rod 20. One end of the limit rod 19 furthest from the limit plate 18 is movably inserted into the insert block 16, locking the insert block 16 and the rotating block 15 using a locking mechanism. A spring 21 is also fitted onto the surface of the telescopic rod 20. One end of the spring 21 is fixedly connected to the rotating block 15, and the other end is fixedly connected to the limit plate 18. The spring 21 is in a compressed state as shown in the figure, thus the spring 21 pushes against the limit plate 18. The position plate 18 tends to move closer to the insertion block 16, which ensures that the limiting rod 19 is stably inserted into the insertion block 16. When the operator moves the limiting plate 18 away from the threaded post 13, the telescopic rod 20 and the spring 21 will shorten, and the limiting rod 19 will disengage from the insertion block 16. This unlocks the insertion block 16 and the rotating block 15, allowing the rotating block 15 to disengage from the insertion block 16. This keeps the threaded post 13 rotating, preventing one end of the threaded post 13 from entering the housing 1 and also preventing the piston 14 from being disassembled from the housing 1.

[0019] In use, rotating the threaded column 13 by rotating the rotating block 15 causes the threaded column 13 to gradually enter the housing 1. The piston 14 squeezes the grease pre-filled in the housing 1 and housing 2 4. Opening the valve on the discharge pipe 8 allows the grease to be discharged. If necessary, the end of the discharge pipe 8 can also be connected to a conventional pipeline, which is existing technology. By forcefully rotating the housing 1 and housing 2 4, the connecting ring 5 will separate from the threaded ring 3, and the housing 1 and housing 2 4 will be disassembled. First, rotating the rotating block 15 causes the threaded column 13 to move on the housing 1, and the piston 14 will move to the outside of the housing 1. Then, by moving the two limiting plates 18, the telescopic rod 20 and the spring 21 will be compressed, and the limiting rod 19 will disengage from the insert block 16. Then, the rotating block 15 will disengage from the insert block 16. By rotating the threaded column 13 by the piston 14, the threaded column 13 will disengage from the housing 1. In this way, the entire filling device is completely disassembled and easy to clean.
