Technical Field

[0001] The utility model relates to the technical field of lubricating oil packaging barrels, in particular to a lubricating oil packaging barrel with controllable oil output volume. Background Technique

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays roles such as lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering. After production, lubricating oil is filled into packaging barrels for sale, and the packaging barrels are used to package and transport the finished lubricating oil.

[0003] A related technology (publication number: CN220866046U) discloses a lubricating oil packaging barrel, and its disclosed technical solution: by providing an oil outlet, the oil can be discharged quickly. By providing a conical oil nozzle, it is possible to accurately drip lubricating oil onto smaller parts or narrow part gaps conveniently. When the barrel body is tilted, it can be kept stable, avoiding the situation of pouring out too much lubricating oil, resulting in waste and polluting other parts and the environment, saving the amount of oil used and reducing the use cost. The lubricating oil in the oil barrel is easy to condense, and ordinary stirring is relatively difficult. By controlling the motor to rotate through a controller, the rotating shaft is driven to rotate, and then the stirring blades are driven to rotate, so that the lubricating oil can be discharged from the oil barrel quickly and smoothly. By providing a protective cover, the motor can be protected from being damaged easily and its service life can be extended.

[0004] In the above-mentioned disclosed technical solution, it is found that the following problems exist in the related technology: when pouring out and using the lubricating oil in the packaging barrel, for some interfaces where the lubricating oil is applied and the size is small, once the amount of oil poured out of the packaging barrel is large, it will cause the lubricating oil to flow outside, resulting in waste. For this reason, we propose a new type of lubricating oil packaging barrel with controllable oil output volume.

[0005] It should be noted that the information disclosed in the above background technical part is only used to strengthen the understanding of the background technical part of this application, and thus may include prior art information that does not constitute known to those of ordinary skill in the art.

A movable column is rotatably arranged at the top of the inner wall of the sealing cap. A flow rate adjustment assembly for adjusting the position of the pipe fitting is arranged between the bottom end of the movable column and the top plug. A lock cap assembly for fixing the sealing cap is arranged at the top of the barrel body.

[0008] In the above technical solution, the flow rate adjustment assembly includes a threaded column arranged at the bottom end of the movable column. A threaded sleeve is fixedly installed at the top of the top plug, and the threaded sleeve is threadedly connected to the outside of the threaded column. The movable column is rotatably arranged at the top of the inner wall of the sealing cap through a base.

[0009] A sealing plug is arranged between the bottom end of the movable column and the top end of the threaded column. The sealing plug corresponds to the inner diameter of the oil pouring port.

[0010] A detachable lock rod assembly is arranged between the sealing plug and the pipe fitting.

[0011] The lock rod assembly includes a positioning rod. An elastic clamping member is arranged at the top of the positioning rod. A clamping hole corresponding to the elastic clamping member is formed on the side wall of the sealing plug. A clamping groove for clamping the positioning rod is formed at the top of the pipe fitting.

[0012] A plurality of balls are evenly arranged in the circumferential direction between the movable column and the base.

[0013] The lock cap assembly includes a support seat fixed to the top of the barrel body. A locking rod penetrates through the inner cavity of the support seat. A limiting block is arranged at the end of the locking rod away from the sealing cap. An elastic member is arranged between the limiting block and the support seat, and the elastic member is sleeved on the outside of the locking rod. A slot hole corresponding to the locking rod is formed on the outer circumferential wall of the sealing cap.

[0014] An oil guiding groove is formed along the edge at the top of the inner wall of the oil pouring port.

[0015] A sliding rod is embedded at the edge of the inner cavity of the barrel body. A floating buoy is sleeved on the outside of the sliding rod.

[0016] An observation window corresponding to the sliding rod is embedded on the side wall of the barrel body.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: This lubricating oil packaging barrel with controllable oil output:

[0018] 1. Adjust the position of the pipe fitting through the flow regulation component, so that the pipe fitting drives the top plug to slide from the inner wall of the oil pouring port into the interior of the barrel. As the part of the flow control hole extending into the barrel increases, the flow port between the inside of the barrel and the oil pouring port becomes larger. Adjust the size of the flow control hole extending into the barrel according to the specifications at the interface during oil pouring, so as to adjust according to the size of the oil receiving port, avoid excessive oil spillage outside, and prevent waste during the oil pouring process.

[0019] 2. When adjusting the size of the flow control hole extending into the barrel, remove the sealing cap and fix it through the lock cap component. Then drive the threaded column to rotate through the movable column, so that the threaded sleeve threadedly connected to the threaded column drives the top plug to move, making the top plug fit against the inner wall of the oil pouring port and move into the barrel. As the top plug moves, the flow control hole on the top plug gradually increases, thereby controlling the oil output of the lubricating oil in the barrel. Adjust according to the size of the oil receiving port at the oil receiving place, and thus it can be applicable to different sizes of oil receiving ports.

[0020] 3. After screwing the sealing cap onto the oil pouring port, the sealing plug moves along with the movable column. As the sealing cap moves, the sealing plug fits against the top of the top plug, improving the sealing performance of the oil pouring port through the sealing plug, and thus preventing oil leakage from the barrel.

[0021] 4. Through the lock rod component, when unscrewing the sealing cap, the top plug forms an integral structure with the sealing plug through the lock rod component, preventing the separation between the top plug and the movable column, and thus avoiding the pipe fitting from falling into the interior of the barrel.

[0022] 5. During the process of rotating the movable column to adjust the opening size of the flow control hole, the movable column drives each ball to fit against the inner wall of the sliding groove through a plurality of circumferential movable grooves respectively. The stability of the rotation process of the movable column is ensured through a plurality of circumferential balls, and thus the accuracy of the adjustment of the opening of the flow control hole is ensured.

[0023] 6. When the circumferential slot of the sealing cap moves to the height corresponding to the locking rod, rotate the sealing cap and turn the slot to the position corresponding to the locking rod. At this time, the locking rod is elastically snapped into the slot on the outer wall of the sealing cap by the elastic force of the elastic member, thereby locking the position of the sealing cap, and thus ensuring the stability of the oil pouring flow regulation process.

[0024] 7. Observe the position of the float through the observation window, so that the remaining amount of the lubricating oil inside the barrel can be understood through the float. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0036] Next, the present utility model will be further described in conjunction with specific implementation cases and attached Figures 1 - 9 drawings, but the present utility model is not limited to these embodiments.

[0037] A lubricating oil packaging barrel with controllable oil output includes a barrel body 1, and an oil pouring port 2 is embedded at the top of the barrel body 1. The oil pouring port 2 is fixedly embedded and installed at the top of the barrel body 1 at the adjacent edge position, so that the oil pouring port 2 is communicated with the inner cavity of the barrel body 1. Part of the external thread is opened downward at the top outer wall of the oil pouring port 2, and the internal thread is opened at the inner wall of the sealing cap 3, so that the sealing cap 3 is screwed onto the oil pouring port 2 by the thread. A sealing cap 3 is threadedly connected to the top of the oil pouring port 2, and a top plug 4 is slidably arranged on the inner wall of the oil pouring port 2. A pipe fitting 5 is arranged at the top of the top plug 4, and flow control holes 6 are evenly opened circumferentially on the outer wall of the pipe fitting 5. The specification of the top plug 4 corresponds to that of the oil pouring port 2, so that the top plug 4 fits and slides on the inner wall of the oil pouring port 2. The pipe fitting 5 is vertically fixed on the top of the top plug 4, and the specification of the pipe fitting 5 corresponds to that of the oil pouring port 2, so that the oil pouring port 2 fits and slides on the inner wall of the oil pouring port 2.

[0038] A week of flow control holes 6 are continuously opened in sequence on the outer wall of the circumference of the pipe fitting 5, and the flow control holes 6 are communicated with the inner cavity of the pipe fitting 5. A guide block 30 is fixedly installed on the outer wall of the side of the pipe fitting 5 away from the oil guiding port 12, and a guide groove 31 is opened on the inner wall of the oil pouring port 2. The guide groove 31 does not penetrate the top, and the guide block 30 fits and slides on the inner wall of the guide groove 31. The sliding fit of the guide groove 31 and the guide block 30 plays a limiting effect on the adjusting direction of the pipe fitting 5, thus ensuring the stability of the adjusting process.

[0039] A movable column 7 is rotatably arranged at the top inner wall of the sealing cap 3, and a flow rate adjusting component for adjusting the position of the pipe fitting 5 is arranged between the bottom end of the movable column 7 and the top plug 4. By adjusting the position of the pipe fitting 5 through the flow rate adjusting component, the pipe fitting 5 drives the top plug 4 to slide from the inner wall of the oil pouring port 2 into the interior of the barrel body 1. As the part of the flow control holes 6 extending into the barrel body 1 increases, the communication port between the barrel body 1 and the oil pouring port 2 becomes larger. The size of the part of the flow control holes 6 extending into the barrel body 1 is adjusted according to the specification at the interface during oil pouring, so as to adjust according to the size of the oil receiving port, avoid excessive oil output and spilling outside, and further prevent waste during the oil pouring process. A lock cap component for fixing the sealing cap 3 is arranged at the top of the barrel body 1.

[0040] During oil pouring, the sealing cap 3 is removed from the oil pouring port 2, and then the sealing cap 3 is fixed above the oil pouring port 2 through the lock cap component. Then, the size of the part of the flow control holes 6 extending into the barrel body 1 is adjusted through the flow rate adjusting component, and the adjustment is made according to the size of the oil receiving interface, which brings convenience to the operation process of relevant personnel, avoids low oil output affecting efficiency, prevents excessive oil output from spilling outside, and further ensures the stability of the oil pouring process.

[0041] Among them, the flow regulating component includes a threaded post 17 provided at the bottom end of the movable column 7. A threaded sleeve 9 is fixedly installed at the top of the top plug 4, and the threaded sleeve 9 is threadedly connected to the outside of the threaded post 17. An internal thread corresponding to the threaded post 17 is provided inwardly at the top of the threaded sleeve 9. The movable column 7 is rotatably arranged at the top of the inner wall of the sealing cap 3 through a base 8. The base 8 is fixedly attached to the top of the inner wall of the sealing cap 3. A groove corresponding to the movable column 7 is provided on the lower surface of the base 8, so that the top end of the movable column 7 is embedded into the groove, and the movable column 7 fits and slides circumferentially on the inner wall of the groove.

[0042] When adjusting the size of the flow control hole 2 extending into the barrel 1, after removing the sealing cap 3 and fixing it through the lock cap assembly, the threaded post 17 is driven to rotate by the movable column 7, so that the threaded sleeve 9 threadedly connected to the threaded post 17 drives the top plug 4 to move, and the top plug 4 fits and moves into the barrel 1 along the inner wall of the oil pouring port 2. As the top plug 4 moves, the flow control hole 6 on the top plug 4 gradually increases, thereby controlling the oil output of the lubricating oil in the barrel 1. It is adjusted according to the size of the oil receiving port at the oil receiving place, and thus can be applicable to oil receiving ports of different sizes.

[0043] It should be noted that a sealing plug 14 is provided between the bottom end of the movable column 7 and the top end of the threaded post 17, and the sealing plug 14 corresponds to the inner diameter of the oil pouring port 2.

[0044] After screwing the sealing cap 3 onto the oil pouring port 2, the sealing plug 14 moves along with the movable column 7, and the sealing plug 14 is embedded into the inner wall of the oil pouring port 2. With the fastening of the sealing cap 3, the sealing performance of the oil pouring port 2 is improved through the sealing plug 14, thereby preventing the barrel 1 from leaking oil.

[0045] In addition, a detachable lock rod assembly is provided between the sealing plug 14 and the pipe fitting 5.

[0046] Through the lock rod assembly, when unscrewing the sealing cap 3, the top plug 4 forms an integral structure with the sealing plug 14 through the lock rod assembly, preventing the top plug 4 from detaching from the movable column 7, thereby avoiding the pipe fitting 5 from falling into the barrel 1.

[0047] In addition, the lock rod assembly includes a positioning rod 18. An elastic clamping member 24 is provided at the top of the positioning rod 18. A clamping hole 22 corresponding to the elastic clamping member 24 is provided on the side wall of the sealing plug 14. A clamping groove 25 for engaging with the positioning rod 18 is provided at the top of the pipe fitting 5. One end of the positioning rod 18 is fixedly installed with an elastic clamping member 24 made of rubber. An elastic rubber clamping post is fixedly installed at the other end of the positioning rod 18, and the shape of the rubber clamping post corresponds to the clamping groove 25.

[0048] When installing the positioning rod 18, the rubber clamping post at the bottom end of the positioning rod 18 is clamped inside the slot 25 at the top of the pipe fitting 5. Then, the elastic clamping member 24 is slid from the bottom of the sealing plug 14 to the clamping hole 22 through elastic deformation. Through the elastic deformation of the elastic clamping member 24, the top end of the positioning rod 18 is driven to be clamped on the clamping hole 22, and the sealing plug 14 is connected to the pipe fitting 5 through the positioning rod 18.

[0049] When adjusting the size of the flow control hole 6 extending into the barrel body 1, the positioning rod 18 is disassembled, and the detachable positioning rod 18 brings convenience to the operation process of relevant personnel.

[0050] Furthermore, ball bearings 19 are circumferentially and evenly arranged between the movable column 7 and the base 8. A sliding groove 21 is formed in the inner wall of the groove of the base 8 in a circle, and a movable groove 20 is continuously formed in a circle on the outer wall of the movable column 7. The ball bearings 19 are movably embedded in each movable cavity formed by the movable groove 20 and the sliding groove 21.

[0051] During the process of rotating the movable column 7 to adjust the opening size of the flow control hole 6, the movable column 7 drives each ball bearing 19 to fit and slide on the inner wall of the sliding groove 21 through a plurality of circumferential movable grooves 20. The stability of the rotation process of the movable column 7 is ensured by a plurality of circumferential ball bearings 19, thereby ensuring the accuracy of the opening adjustment of the flow control hole 6.

[0052] The lock cap assembly includes a support 15 fixed to the top of the barrel body 1. The bottom of the fixed column 13 is vertically fixed at a position corresponding to the top of the barrel body 1 and opposite to the sealing cap 3, and the support 15 is fixedly installed at the top of the fixed column 13. A locking rod 16 is arranged through the inner cavity of the support 15. A limiting block 26 is arranged at the end of the locking rod 16 away from the sealing cap 3. An elastic member 27 is arranged between the limiting block 26 and the support 15, and the elastic member 27 is sleeved outside the locking rod 16. The elastic member 27 can be a compression spring. The two ends of the elastic member 27 are respectively fixed on the opposite surfaces of the support 15 and the limiting block 26, and the elastic member 27 is movably sleeved outside the locking rod 16, so that the elastic member 27 fits and slides on the outer wall of the locking rod 16. A slot hole corresponding to the locking rod 16 is formed on the outer circumferential wall of the sealing cap 3.

[0053] After the sealing cap 3 is removed, since the top plug 4 is located inside the oil pouring port 2, the sealing cap 3 moves in the vertical direction. When the circumferential slot hole of the sealing cap 3 moves to a height corresponding to the locking rod 16, the sealing cap 3 is rotated to rotate the slot hole to a position corresponding to the locking rod 16. At this time, the locking rod 16 is clamped into the slot hole on the outer wall of the sealing cap 3 by the elastic force of the elastic member 27, thereby locking the position of the sealing cap 3, and further ensuring the stability of the oil pouring flow rate adjustment process.

[0054] An oil guide groove 12 is provided along the edge at the top of the inner wall of the oil pouring port 2. Through the oil guide groove 12 at the top edge of the oil pouring port 2, the oil poured out of the barrel body 1 is discharged along the oil guide groove 12, thereby preventing the lubricating oil from flowing out and running down the outer wall of the barrel body 1.

[0055] A sliding rod 28 is embedded at the edge of the inner cavity of the barrel body 1, and a floating buoy 29 is sleeved outside the sliding rod 28. The sliding rod 28 is fixedly installed at a position close to the inner wall in the inner cavity of the barrel body 1. The top end of the sliding rod 28 is vertically fixed to the top of the inner wall of the barrel body 1, and the bottom end of the sliding rod 28 is vertically fixed to the bottom of the inner wall of the barrel body 1. The floating buoy 29 is movably sleeved outside the sliding rod 28 through a through hole opened at the center, and the remaining amount of the lubricating oil inside the barrel body 1 can be understood through the floating buoy 29.

[0056] An observation window 10 corresponding to the sliding rod 28 is embedded in the side wall of the barrel body 1. The observation window 10 is fixedly embedded and installed on the side wall of the barrel body 1, and the observation window 10 is in a position parallel to the sliding rod 28. The observation window 10 is made of a transparent material, so that the remaining amount of oil in the barrel can be understood more clearly.

[0057] The working principle of a lubricating oil packaging barrel with controllable oil output in this embodiment is as follows: When pouring oil, the sealing cap 3 is removed from the oil pouring port 2. Since the top plug 4 is located inside the oil pouring port 2, the sealing cap 3 moves in the vertical direction. When the circumferential slot of the sealing cap 3 moves to the height corresponding to the locking rod 16, the sealing cap 3 is rotated, and the slot is rotated to the position corresponding to the locking rod 16. At this time, the locking rod 16 is snapped into the slot on the outer wall of the sealing cap 3 by the elastic force of the elastic member 27, thereby locking the position of the sealing cap 3.

[0058] Then, the elastic clamping member 24 is removed from the clamping hole 22 at the bottom of the sealing plug 14 through elastic deformation, and the positioning rod 18 is disassembled from the sealing plug 14 and the pipe fitting 5.

[0059] After that, the movable column 7 drives the threaded column 17 to rotate, so that the threaded sleeve 9 threadedly connected to the threaded column 17 drives the top plug 4 to move. The top plug 4 fits against the inner wall of the oil pouring port 2 and moves into the barrel body 1. As the top plug 4 moves, the flow control holes 6 on the top plug 4 gradually increase, thereby controlling the oil output of the lubricating oil in the barrel body 1.
