Description

Technical Field

[0001] This utility model relates to the field of lubricating oil filling gun technology, and in particular to a convenient industrial lubricating oil filling gun. Background Technology

[0002] In industrial production, the stable operation of various mechanical equipment relies on timely and effective lubrication and maintenance. Key components such as bearings, gears, and guide rails experience wear and heat due to friction during high-speed operation or long-term work. Insufficient or untimely lubrication can not only reduce equipment efficiency but also lead to component damage, equipment malfunction, and even production interruptions, resulting in significant economic losses.

[0003] Traditional spring-driven lubrication systems rely on the elastic deformation of the spring to generate thrust and expel grease. Operators often need to overcome the spring's elasticity during operation, which significantly increases labor intensity and can easily lead to fatigue, ultimately affecting lubrication efficiency.

[0004] In response to the technical problem that traditional spring-driven methods rely on the elastic deformation of the spring to generate thrust to squeeze out grease, this application proposes a convenient industrial lubricating oil filling gun. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of traditional spring-driven methods that rely on the elastic deformation of the spring to generate thrust for grease extrusion. A convenient industrial lubricant filling gun is proposed, which uses negative pressure to extrude grease to various lubrication points without the need for traditional spring-driven methods. Compared to traditional spring-driven methods, this method is more convenient, lighter, and faster, providing users with numerous benefits and reducing grease waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a convenient industrial lubricating oil filling gun, including a connector, a metal gun barrel detachably connected to the inner wall of the bottom end of the connector, a grease tube provided on the inner wall of the metal gun barrel, a double pressure shaft slidably connected to the inner wall of the connector, a one-way valve fixedly connected to the top end of the connector, an oil pipe fixedly connected to the top end of the one-way valve, and a gun head fixedly connected to the top end of the oil pipe.

[0007] Furthermore, a sliding piston is slidably connected to the inner wall of the grease tube, the top end of the grease tube is tightly attached to the bottom end of the inner wall of the connector, and the outer wall of the grease tube is attached to the inner wall of the metal gun barrel.

[0008] Furthermore, the top end of the grease hose is provided with a hose pull ring for sealing the grease hose.

[0009] Furthermore, a support rod is fixedly connected to the top of the connector, and a pressure rod is rotatably connected to the other end of the support rod. The inner wall of the pressure rod is provided with a movable groove.

[0010] Furthermore, a connecting shaft is fixedly connected to the left end of the dual pressure shaft, and the outer wall of the connecting shaft is sleeved on the inner wall of the movable groove.

[0011] Furthermore, a handle is fixedly connected to the other end of the pressure rod, the outer wall of the handle is provided with an anti-slip groove, and multiple anti-slip protrusions are fixedly connected to the inner side of the handle.

[0012] Furthermore, the tubing is made of thermoplastic material to allow it to be bent.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, by pulling the pressure rod, the double pressure shaft moves outward, creating negative pressure inside the grease tube and moving the sliding piston upward, thereby bringing the lubricating oil up and ejecting it from the nozzle. This achieves the goal of squeezing the grease to various lubrication points through negative pressure, without the need for traditional spring-driven methods. Compared to the traditional spring-driven method of squeezing grease, this method is more convenient, lighter, and faster, bringing many conveniences to users and reducing grease waste.

[0019] 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.

[0020] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a convenient industrial lubricating oil filling gun, including a connector 1. A metal gun barrel 10 is detachably threaded onto the inner wall of the bottom end of the connector 1. A grease hose 11 is disposed on the inner wall of the metal gun barrel 10. A double pressure shaft 2 is slidably connected to the inner wall of the connector 1. A one-way valve 7 is fixedly connected to the top end of the connector 1. An oil pipe 8 is fixedly connected to the top end of the one-way valve 7. A gun head 9 is fixedly connected to the top end of the oil pipe 8. A sliding piston 12 is slidably connected to the inner wall of the grease hose 11. The top end of the grease hose 11 is tightly attached to the bottom end of the inner wall of the connector 1, and the outer wall of the grease hose 11 is flush with the metal gun barrel. The inner wall of the grease hose 11 is fitted together. The top end of the grease hose 11 is provided with a hose pull ring 13 for sealing the grease hose 11. The top end of the connector 1 is fixedly connected to a support rod 3. The other end of the support rod 3 is rotatably connected to a pressure rod 5. The inner wall of the pressure rod 5 is provided with a movable groove 14. The left end of the double pressure shaft 2 is fixedly connected to a connecting shaft 4. The outer wall of the connecting shaft 4 is sleeved on the inner wall of the movable groove 14. The other end of the pressure rod 5 is fixedly connected to a handle 6. The outer wall of the handle 6 is provided with an anti-slip groove. Multiple anti-slip protrusions are fixedly connected to the inner side of the handle 6. The oil hose 8 is made of thermoplastic material so that the oil hose 8 can be bent.

[0021] Specifically, the interior of connector 1 is connected to the interior of the double pressure shaft 2 and the grease hose 11. The one-way valve 7 only allows gas to move outward from the inner wall of connector 1, while gas from the outside cannot enter the interior of connector 1 through the one-way valve 7. This causes the internal space of connector 1 to increase and the pressure to decrease when the double pressure shaft 2 moves out of connector 1, creating a negative pressure that causes the sliding piston 12 to move upward. Conversely, when the double pressure shaft 2 slides into connector 1, the internal space decreases and the pressure increases, thus forcing lubricating oil into the oil pipe 8. The oil pipe 8 is made of thermoplastic, allowing it to bend and enabling the addition of lubricating oil to the machine's interior in complex environments.

[0022] Working principle: In use, pull open the easy-open ring 13 at the top of the new grease hose 11 to expose the top of the grease hose 11. Then rotate the metal gun barrel 10 to make it rotate down from the bottom of the connector 1. Then insert the opened grease hose 11 into the metal gun barrel 10. Then rotate the metal gun barrel 10 at the bottom of the connector 1 to connect it with the connector 1, thus fixing the grease hose 11 to the bottom of the connector 1. When adding lubricating oil to the machine, align the gun head 9 with the adding position, and then pull up the handle 6. The handle 6 drives the pressure rod 5 to rotate, and the pressure rod 5 drives the connecting shaft 4 to move to the left through the movable groove 14. When the connecting shaft 4 moves, the double pressure shaft 2 moves to the left. When the double pressure shaft 2 moves to the left, it moves outward from inside the connector 1, thereby generating negative pressure. The sliding piston 12 moves upward inside the grease hose 11, thereby squeezing the lubricating oil inside the grease hose 11 upward and into the connector 1. When the pressure rod 5 is pressed, the pressure rod 5 will move the double pressure shaft 2 into the connector 1 through the movable groove 14 and the connecting shaft 4, thereby increasing the pressure inside the connector 1 and squeezing the lubricating oil into the one-way valve 7. The lubricating oil then enters the oil pipe 8 through the one-way valve 7, and then enters the gun head 9 from the oil pipe 8, and finally enters the mechanical part that needs to be lubricated from the gun head 9.

[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. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
