Description

Technical Field

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

[0002] In magnetron sputtering coating lines, hydraulic oil guns are often used to supply lubricating oil to the Roots pump. This reduces friction and wear on critical moving parts such as bearings and gears inside the pump, ensuring normal operation and extending its service life. Furthermore, hydraulic oil guns are also used to pressurize and supply oil to the pump's components during maintenance.

[0003] Hydraulic oil guns commonly used in the market are bulky and not easy to carry. Moreover, the oil hoses used for installation and use are threaded hoses, and the entire hose needs to be rotated in the direction that the connector is fixed when connecting them. In addition, the hoses are large and have a complex structure, so this operation is quite time-consuming and laborious. Utility Model Content

[0004] The main purpose of this utility model is to propose a hydraulic oil gun that solves the problem that existing hydraulic oil guns use hoses for connection, resulting in a large overall size and difficulty in carrying them.

[0005] To achieve the above objectives, the hydraulic oil gun proposed in this utility model includes:

[0006] The first oil gun tube has an oil nozzle outlet at one end and a connector at the other end, and the interior of the first oil gun tube has a first channel.

[0007] The second oil gun tube has a second channel inside and a docking part at one end. The docking part is sleeved on the connector of the first oil gun tube. The first channel and the second channel are connected to form an oil passage. The second oil gun tube can move relative to the first oil gun tube along the axial direction.

[0008] The hydraulic gun rod is placed in the oil passage. A sealing ring is fitted around the outer periphery of the end of the hydraulic gun rod near the outlet of the first hydraulic gun tube. The sealing ring forms a sealing fit with the inner wall of the first hydraulic gun tube, so that a sealed chamber is formed between the outlet of the nozzle and the sealing ring. The sealed chamber is used to store hydraulic oil. The other end of the hydraulic gun rod abuts against the end of the second hydraulic gun tube away from the first hydraulic gun tube.

[0009] The second oil gun tube moves toward the nozzle outlet to drive the oil gun rod to move, thereby causing the oil gun rod to squeeze the hydraulic oil in the sealed chamber out of the nozzle outlet.

[0010] In some embodiments, the outer periphery of the connector is provided with an external thread section, the inner periphery of the mating portion is provided with an internal thread section, the mating portion is threadedly connected to the connector, and the second oil gun tube can rotate relative to the connector portion in the direction of the oil nozzle outlet to push the oil gun rod to move.

[0011] In some embodiments, an adapter is installed at the end of the first oil gun tube where the oil nozzle outlet is located.

[0012] In some embodiments, the first oil gun tube includes a tube body and an oil outlet, the oil outlet being fixedly connected to the tube body, the oil outlet having the oil nozzle outlet, and the tube body protruding outward relative to the oil outlet to form a stop boss for blocking the movement of the adapter.

[0013] In some embodiments, the inner diameter of the nozzle outlet is smaller than the inner diameter of the first channel.

[0014] In some embodiments, a limiting groove is recessed on the outer periphery of the oil gun rod, and the sealing ring is sleeved in the limiting groove; preferably, there are multiple sealing rings, and the number of limiting grooves corresponds to the number of sealing rings.

[0015] In some embodiments, the hydraulic gun further includes a disassembly component, wherein the end of the gun rod away from the nozzle outlet of the first gun tube is provided with an internal thread; one end of the disassembly component is provided with an external thread, which is adapted to the internal thread of the gun rod; wherein the external thread of the disassembly component engages with the internal thread of the gun rod to apply torque to the gun rod body, thereby disengaging the gun rod body from the installation position.

[0016] In some embodiments, the end of the oil gun rod facing the nozzle outlet is provided with a rounded corner structure.

[0017] In some embodiments, the end of the second oil gun tube away from the docking portion is provided with a locking portion for the wrench to engage.

[0018] In some embodiments, the locking part has a hexagonal screw structure.

[0019] The technical solution of this utility model employs a first hydraulic gun tube with an oil nozzle outlet at one end and a connector at the other end; and a second hydraulic gun tube with a connecting part at one end, which connects to the connector of the first hydraulic gun tube. The first and second channels communicate to form an oil passage, allowing the second hydraulic gun tube to move axially relative to the first hydraulic gun tube without the need for an external hose. Furthermore, an oil gun rod is added and placed within the oil passage. A sealing ring is fitted around the outer circumference of the end of the oil gun rod near the oil nozzle outlet of the first hydraulic gun tube, forming a sealed fit with the inner wall of the first hydraulic gun tube to create a closed chamber for storing hydraulic oil. The other end of the oil gun rod abuts against the end of the second hydraulic gun tube furthest from the first hydraulic gun tube. In actual operation, operating the assembled hydraulic gun and moving the second hydraulic gun tube towards the oil nozzle outlet drives the oil gun rod, causing it to expel the hydraulic oil from the closed chamber through the oil nozzle outlet. This eliminates the need for an external hose, simplifying the refueling operation. The assembled hydraulic gun is also small and portable. Attached Figure Description

[0031] In magnetron sputtering coating lines, hydraulic oil guns are often used to supply lubricating oil to the Roots pump. This reduces friction and wear on critical moving parts such as bearings and gears inside the pump, ensuring normal operation and extending its service life. Furthermore, hydraulic oil guns are also used to pressurize and supply oil to the pump's components during maintenance.

[0032] Hydraulic oil guns commonly used in the market are bulky and not easy to carry. Moreover, the oil hoses used for installation and use are threaded hoses, and the entire hose needs to be rotated in the direction that the connector is fixed when connecting them. In addition, the hoses are large and have a complex structure, so this operation is quite time-consuming and laborious.

[0033] This utility model discloses a hydraulic oil gun 100. Please refer to [link / reference]. Figures 1 to 3In one embodiment of this utility model, the hydraulic gun 100 includes a first gun tube 10, a second gun tube 20, and a gun rod 30. One end of the first gun tube 10 has a nozzle outlet 121, and the other end has a connector 111. The first gun tube 10 has a first channel 112 inside. The second gun tube 20 has a second channel 21 inside. One end of the second gun tube 20 has a connecting portion 22, which is fitted onto the connector 111 of the first gun tube 10. Channel 112 communicates with the second channel 21 to form an oil passage 23, and the second oil gun tube 20 can move relative to the first oil gun tube 10 along the axial direction. The oil gun rod 30 is placed in the oil passage 23, and a sealing ring 31 is fitted around the outer periphery of the end of the oil gun rod 30 near the oil nozzle outlet 121 of the first oil gun tube. The sealing ring 31 forms a sealing fit with the inner wall of the first oil gun tube 10, so that a sealed chamber is formed between the oil nozzle outlet 121 and the sealing ring 31. The sealed chamber is used to store hydraulic oil. The other end of the oil gun rod 30 abuts against the end of the second oil gun tube 20 away from the first oil gun tube 10.

[0034] The second oil gun tube 20 moves toward the oil nozzle outlet 121 to drive the oil gun rod 30 to move, thereby causing the oil gun rod 30 to squeeze the hydraulic oil in the sealed chamber out of the oil nozzle outlet 121.

[0035] Optionally, the second oil gun tube 20 and the first oil gun tube 10 can be configured as a sleeve structure, fitting together so that the second oil gun tube 20 can fit over the outside of the first oil gun tube 10 and can move up and down relative to the first oil gun tube 10, thereby pushing the oil gun rod 30 inside the second oil gun tube 20 to move.

[0036] The second oil gun tube 20 and the first oil gun tube 10 can be movably connected by a threaded connection. The second oil gun tube 20 can rotate clockwise or counterclockwise outside the first oil gun tube 10, pushing the oil gun rod 30 inside the second oil gun tube 20 to move. In one embodiment, the second oil gun tube 20 and the first oil gun tube 10 are connected by a threaded engagement, so that the second oil gun tube 20 pressurizes the oil gun rod 30 and prevents the oil gun rod 30 from resetting away from the nozzle outlet 121, ensuring that the oil gun rod 30 is smoothly pushed towards the nozzle outlet 121, thereby squeezing the hydraulic oil in the sealed chamber out from the nozzle outlet 121.

[0037] The technical solution of this utility model involves setting an oil nozzle outlet 121 at one end of a first oil gun tube 10 and a connector 111 at the other end; and setting a docking part 22 at one end of a second oil gun tube 20, the docking part 22 being connected to the connector 111 of the first oil gun tube 10. The first channel 112 and the second channel 21 are connected to form an oil passage 23, allowing the second oil gun tube 20 to move relative to the first oil gun tube 10 along the axial direction without the need for an external hose. Furthermore, an oil gun rod 30 is added, and the oil gun rod 30 is placed in the oil passage 23. A sealing ring 31 is fitted around the outer periphery of the end of the oil gun rod 30 near the oil nozzle outlet 121 of the first oil gun tube. The sealing ring 31 forms a sealing fit with the inner wall of the first oil gun tube 10, creating a sealed chamber between the oil nozzle outlet 121 and the sealing ring 31, which stores hydraulic oil. The other end of the oil gun rod 30 abuts against the end of the second oil gun tube 20 away from the first oil gun tube 10. In actual operation, the assembled hydraulic gun 100 is operated, and the second oil gun tube 20 is moved towards the oil nozzle outlet 121 to drive the oil gun rod 30 to move, thereby causing the oil gun rod 30 to squeeze the hydraulic oil in the sealed chamber out of the oil nozzle outlet 121. There is no need to connect an external hose, the oil filling operation is simple, and the assembled hydraulic gun 100 is small in size and easy to carry.

[0038] When it is not necessary to add oil to the Roots pump, the second oil gun tube 20 is removed from the first oil gun tube 10 by rotating it counterclockwise, and then the oil gun rod 30 inside the first oil gun tube 10 is taken out, thus completing the disassembly of the hydraulic oil gun 100 for easy carrying.

[0039] When the hydraulic gun 100 is needed, first, the sealing ring 31 is fitted into the corresponding limiting groove 32 of the gun rod 30. Then, the gun rod 30 with the sealing ring 31 is inserted into the first gun tube 10. Next, the second gun tube 20 is screwed into the first gun tube 10 via a threaded connection. Finally, the second gun tube 20 can be rotated with a wrench to move towards the nozzle outlet 121, thereby driving the gun rod 30 to move and causing it to squeeze the hydraulic oil in the sealed chamber out of the nozzle outlet 121.

[0040] In some embodiments, the outer periphery of the connector 111 is provided with an external thread section, and the inner periphery of the mating part 22 is provided with an internal thread section. The mating part 22 is threadedly connected to the connector 111, and the mating part 22 is rotatable from the connector 111 and moves in the direction of the oil nozzle outlet 121.

[0041] The second oil gun tube 20 is rotatable relative to the connector 111 in the direction of the oil nozzle outlet 121, so as to push the oil gun rod 30 to move.

[0042] The outer periphery of the connector 111 is provided with a long section of M20 external thread, and the inner wall of the mating part 22 is correspondingly provided with a long section of M20 internal thread. The mating part 22 and the connector 111 are connected by a threaded connection, and the mating part 22 can rotate clockwise or counterclockwise outside the connector 111.

[0043] In another embodiment, please refer to Figure 3 The first oil gun tube 10 has an adapter 40 installed at the end where the oil nozzle outlet 121 is located.

[0044] To facilitate the connection between the hydraulic oil gun 100 and the inlet of the Roots pump for convenient lubrication of the internal parts of the Roots pump, an adapter 40 is installed at the end of the first oil gun tube 10 with an oil nozzle outlet 121. The adapter 40 can be inserted into the inlet of the Roots pump. The hydraulic oil in the sealed chamber is squeezed out from the oil nozzle outlet 121 and then flows through the adapter 40 into the inlet of the Roots pump, and subsequently into the internal parts of the Roots pump.

[0045] Please see Figure 2 and Figure 3 The first oil gun tube 10 includes a tube body 11 and an oil outlet 12. The oil outlet 12 is fixedly connected to the tube body 11. The oil outlet 12 is provided with the oil nozzle outlet 121. The tube body 11 protrudes outward relative to the oil outlet 12 to form a blocking boss 113 for blocking the movement of the adapter 40, so that the adapter 40 is positioned on the oil outlet 12. The adapter 40 is connected to the oil outlet 12.

[0046] In some embodiments, the inner diameter of the nozzle outlet 121 is smaller than the inner diameter of the first channel 112.

[0047] Please see Figure 1 and Figure 2 The outer periphery of the oil gun rod 30 is recessed with a limiting groove 32, and the sealing ring 31 is sleeved in the limiting groove 32. Preferably, there are multiple sealing rings 31, and the number of limiting grooves 32 corresponds to the number of sealing rings 31.

[0048] In one embodiment, the oil gun rod 30 is provided with three limiting grooves 32. To use the hydraulic oil gun 100, three sealing rings 31 need to be fitted onto the limiting grooves 32 first, and then the oil gun rod 30 with the three sealing rings 31 fitted onto it is inserted into the first oil gun tube 10. The sealing rings 31 can play a sealing role in the first channel 112 of the first oil gun tube 10.

[0049] In one embodiment, the end of the oil gun rod 30 facing the oil nozzle outlet 121 is provided with a rounded corner structure so that the oil gun rod 30 can be smoothly inserted into the first oil gun tube 10.

[0050] In one embodiment, the second oil gun tube 20 is provided with a locking part 24 at the end away from the docking part 22, the locking part 24 being used for locking the wrench.

[0051] The operator uses a wrench to operate the second oil gun tube 20, rotating it clockwise around the first oil gun tube 10. The second oil gun tube 20 moves closer to the nozzle outlet 121. The oil gun rod 30 within the oil passage 23 is pushed and compressed by the inner top wall of the second oil gun tube 20, moving towards the nozzle outlet 121, allowing the hydraulic oil in the sealed chamber to exit through the nozzle outlet 121. During this process, the sealing ring 31 of the oil gun rod 30 also prevents hydraulic oil backflow.

[0052] The hydraulic gun 100 also includes a disassembly component. The end of the gun rod 30 away from the nozzle outlet 121 of the first gun tube is provided with an internal thread. One end of the disassembly component is provided with an external thread, which is adapted to the internal thread of the gun rod 30. The external thread of the disassembly component is screwed into the internal thread of the gun rod 30 to apply torque to the gun rod 30, thereby disengaging the gun rod 30 from the installation position.

[0053] In one embodiment, the second oil gun tube 20 can be separated from the first oil gun tube 10 using a wrench. Then, a disassembly component with external threads is screwed onto the oil gun rod 30. Torque is then applied to the oil gun rod 30 by rotating the disassembly component, causing the oil gun rod 30 to unscrew from the first oil gun tube 10, thus disassembling the oil gun rod 30 from its mounting position.

[0054] In one embodiment, the locking part 24 has a hexagonal screw structure so that a wrench can be locked onto the locking part, thereby facilitating the rotation of the second oil gun tube 20 by driving the wrench.

[0055] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
