Abstract
Description

[0001] This utility model relates to the field of mechanical lubricating oil storage technology, and in particular to a lubricating oil storage device. Background Technology
[0002] To facilitate the handling and storage of lubricating oil and improve its storage effectiveness, lubricating oil storage devices are typically used. These devices prevent the lubricating oil from directly contacting the external environment, thus preventing contamination. They also include an outlet valve, which allows the lubricating oil to be dispensed.
[0003] The existing lubricating oil storage device does not have a measuring structure at the outlet. When users take lubricating oil, they need to pour it into a measuring tool to measure the volume of the poured lubricating oil. This method of taking lubricating oil requires the use of a measuring tool, and some lubricating oil will adhere to the surface of the measuring tool, resulting in waste of resources. In addition, the measuring tool needs to be cleaned after taking the oil, which increases the workload. Utility Model Content

The main pipeline is connected to the end of the first butterfly valve away from the oil outlet pipe. The starting end of the extension pipe is movably fitted with the outer surface of the main pipeline. The bottom wall of the starting end of the extension pipe is movably abutting against the surface of the end of the main pipeline.

[0008] In one embodiment, the extension tube has a movable cavity, a first internal thread is formed around the side wall of the movable cavity, and a first external thread is formed around the outer surface of the main pipe, wherein the first internal thread and the first external thread mesh with each other.
[0009] In one embodiment, the lubricating oil storage device further includes: two first sealing rings, one of which has a first end bonded to the surface of the end of the main pipe, and the other of which has a second end bonded to the starting end of the elastic telescopic tube, the first end of the other sealing ring bonded to the bottom wall of the movable cavity, and the second end of the other first sealing ring bonded to the end of the elastic telescopic tube, the outer surface of the elastic telescopic tube abutting against the side wall of the movable cavity.
[0010] In one embodiment, a first connecting pipe is provided at each end of the first butterfly valve. One first connecting pipe is connected to the oil outlet pipe, and the other first connecting pipe is connected to the main pipe. The inner diameter of the flow channel of the two first connecting pipes is equal to the inner diameter of the flow channel of the oil outlet pipe. The two first connecting pipes, the oil outlet pipe, and the main pipe are interconnected.
[0011] In one embodiment, a second connecting pipe is provided at the first end of the second butterfly valve, the oil drain pipe is provided at the second end of the second butterfly valve, the second connecting pipe is connected to the extension pipe, and the inner diameter of the flow channel of the second connecting pipe is equal to the inner diameter of the flow channel of the extension pipe and the two are interconnected.

Detailed Implementation
[0024] Example 1
[0025] A lubricating oil storage device, such as Figures 1 to 5 As shown, the system includes: an oil storage tank 10, a first butterfly valve 20, a main pipeline 50, an extension pipe 60, and a second butterfly valve 30. The oil storage tank 10 has an oil storage chamber 11, and an oil outlet pipe 12 communicating with the oil storage chamber 11 is provided on the outer surface of the oil storage tank 10. The first butterfly valve 20 has a first oil passage 22, and the oil outlet pipe 12 is connected to the end of the first butterfly valve 20 closest to the oil outlet pipe 12. The main pipeline 50 is connected to the end of the first butterfly valve 20 furthest from the oil outlet pipe 12. The starting end of the extension pipe 60 is movably fitted with the outer surface of the main pipeline 50, and the bottom wall of the starting end of the extension pipe 60 is movably abutting against the surface of the end of the main pipeline 50. An elastic telescopic tube 70 is fixedly connected between the end surface of the extension tube 60 and the bottom wall of the starting end of the extension tube 60. A transparent observation window 61 is provided on the outer surface of the extension tube 60, and a measuring ruler 62 is provided on the surface of the observation window 61. A second oil passage 31 is opened inside the second butterfly valve 30. The end of the extension tube 60 is connected to the end of the second butterfly valve 30 near the extension tube 60. An oil drain pipe 33 is provided at the end of the second butterfly valve 30 away from the extension tube 60. The inner diameters of the flow channels 63 of the oil outlet pipe 12, the first oil passage 22, the main pipe 50, the extension tube 60, the second oil passage 31, the elastic telescopic tube 70, and the oil drain pipe 33 are all equal and connected in sequence.
[0026] The oil outlet pipe 12, the first oil passage 22, the main pipe 50, the extension pipe 60, the second oil passage 31, the elastic telescopic pipe 70, and the drain pipe 33 together form the discharge pipe component. By assembling the discharge pipe component in the oil storage tank 10, a lubricating oil storage device that can accurately extract oil on demand can be formed.
[0027] It should be noted that in Embodiment 1, the starting end is the end closer to the oil storage tank 10, and the ending end is the end farther away from the oil storage tank 10.
[0028] Specifically, in use, the first valve 21 of the first butterfly valve 20 can open or close the first oil passage 22. When it is necessary to measure lubricating oil, the first valve 21 of the first butterfly valve 20 opens the first oil passage 22, and the lubricating oil in the oil storage chamber 11 can flow into the main pipeline 50, the elastic telescopic tube 70, and the flow channel 63 of the extension tube 60 through the oil outlet pipe 12. When different amounts of lubricating oil need to be taken, the extension tube 60 is moved, causing the extension tube 60 to move on the outer surface of the main pipeline 50. At this time, the length of the elastic telescopic tube 70 is dynamically adjusted under the traction of the extension tube 60 to compensate for the distance between the extension tube 60 and the main pipeline 50 when the extension tube 60 moves. The height difference in the flow channels 63, due to the equal inner diameters of the flow channels 63 between the main pipe 50, extension pipe 60, and elastic expansion pipe 70, allows the lubricating oil to flow smoothly through the elastic expansion pipe 70 and then into the flow channel 63 of the extension pipe 60. This avoids measurement errors caused by the height difference of the extension pipe 60 moving on the main pipe 50. The volume of lubricating oil in the pipe can be read using the scale on the transparent observation window 61. When oil needs to be taken, the second valve of the second butterfly valve 30 is opened to open the second oil passage 31, and the first butterfly valve 20 is closed to isolate the first oil passage, thereby allowing the lubricating oil in the area from the main pipe 50 to the drain pipe 33 to be discharged through the drain pipe 33. It should be noted that the butterfly valve is a commonly used component for controlling the opening and closing of pipelines by those skilled in the art; therefore, its working principle and structure will not be described in detail.
[0029] The length from the middle of the first oil passage 22 to the end of the main pipe 50 is d1, and the length from the initial end of the extension pipe 60 (in its stationary state) to the middle of the second oil passage 31 is d2. Since the inner diameters of the flow channels 63 of the oil outlet pipe 12, the first oil passage 22, the main pipe 50, the extension pipe 60, the second oil passage 31, the elastic telescopic pipe 70, and the oil discharge pipe 33 are all equal, all being r, the volume of lubricating oil stored from the middle of the first oil passage 22 to the middle of the second oil passage 31 when the extension pipe 60 is stationary is: An initial graduation is set at the beginning of the extension tube 60, and the volume at this point is marked as V. The distance X that the extension tube 60 needs to move to store an additional 1 mL from the middle of the first oil passage 22 to the middle of the second oil passage 31 can be calculated using the formula above. Therefore, for every X movement of the extension tube 60, 1 mL more lubricating oil is stored in the middle of the first oil passage 22 to the middle of the second oil passage 31. A mark is set every X on the transparent observation window 61 along the forward direction of the extension tube 60, so that the volume of lubricating oil stored in the middle of the first oil passage 22 to the middle of the second oil passage 31 can be read through the observation window 61.
[0030] Preferably, the extension tube 60 has a movable cavity 64 inside, a first internal thread 65 is formed around the side wall of the movable cavity 64, and a first external thread 51 is formed around the outer surface of the main pipe 50. The first internal thread 65 and the first external thread 51 mesh with each other. The extension tube 60 can be screwed into or out of the main pipe 50 by rotation to change the distance from the middle of the first oil passage 22 to the middle of the second oil passage 31, thereby changing the volume of lubricating oil stored.
[0031] Preferably, the lubricating oil storage device further includes: two first sealing rings 40, one first sealing ring 40 having its first end bonded to the surface of the end of the main pipe 50, and the second end of the first sealing ring 40 bonded to the starting end of the elastic telescopic tube 70; the first end of the other sealing ring is bonded to the bottom wall of the movable cavity 64, and the second end of the other first sealing ring 40 is bonded to the end of the elastic telescopic tube 70; the outer surface of the elastic telescopic tube 70 abuts against the side wall of the movable cavity 64. The two first sealing rings 40 ensure that lubricating oil does not leak when flowing from the main pipe 50 into and out of the elastic telescopic tube 70. The adhesive bonding method allows the two first sealing rings 40 to be securely installed at the end of the main pipe 50 and the bottom wall of the movable cavity 64, thereby improving the stability of the lubricating oil flow.
[0032] Preferably, each end of the first butterfly valve 20 is provided with a first connecting pipe 23. One first connecting pipe 23 is connected to the oil outlet pipe 12, and the other first connecting pipe 23 is connected to the main pipe 50. The inner diameter of the flow channel 63 of both first connecting pipes 23 is equal to the inner diameter of the flow channel 63 of the oil outlet pipe 12. The two first connecting pipes 23, the oil outlet pipe 12, and the main pipe 50 are interconnected. Using two first connecting pipes 23 can prevent the oil outlet pipe 12 and the main pipe 50 from being directly connected to the first oil passage 22, thereby improving the stability of lubricating oil flow.
[0033] Preferably, a second connecting pipe 32 is provided at the first end of the second butterfly valve 30, and an oil drain pipe 33 is provided at the second end of the second butterfly valve 30. The second connecting pipe 32 is connected to the extension pipe 60, and the inner diameter of the flow channel 63 of the second connecting pipe 32 is equal to the inner diameter of the flow channel 63 of the extension pipe 60, and the two are interconnected. The use of the second connecting pipe 32 can avoid the end of the extension pipe 60 from being directly connected to the second oil passage 31, thereby improving the stability of lubricating oil flow.
[0034] Preferably, the lubricating oil storage device further includes: a plurality of second sealing rings 41; a connecting cavity 52 is provided at the starting end of the main pipe 50, the second connecting pipe 32, and the first connecting pipe 23 near the oil outlet pipe 12; each second sealing ring 41 is disposed on the bottom wall of a connecting cavity 52; the ends of the oil outlet pipe 12, the extension pipe 60, and the first connecting pipe 23 away from the oil outlet pipe 12 are all located in their corresponding connecting cavities 52; the ends of the oil outlet pipe 12, the extension pipe 60, and the first connecting pipe 23 away from the oil outlet pipe 12, together with the bottom wall of their corresponding connecting cavities 52, abut against the second sealing ring 41. By providing connecting cavities 52 at the starting ends of the main pipe 50, the second connecting pipe 32, and the first connecting pipe 23 near the oil outlet pipe 12, assembly space is provided for the oil outlet pipe 12, the extension pipe 60, and the first connecting pipe 23 away from the oil outlet pipe 12, allowing them to be spliced together and clamping their respective second sealing rings 41, thus preventing leakage of lubricating oil during flow.
[0035] Preferably, a second internal thread 521 is provided on the sidewall surrounding each engagement cavity 52, and a second external thread 121 is provided on the outer surface surrounding the oil outlet pipe 12, the extension pipe 60, and the first connecting pipe 23. Each second external thread 121 meshes with its corresponding second internal thread 521. This arrangement facilitates the loading and unloading of the oil outlet pipe 12 with the first connecting pipe 23 near the oil outlet pipe 12, the extension pipe 60 and the second connecting pipe 32, the main pipe 50, and the first connecting pipe 23 away from the oil outlet pipe 12.
[0036] Preferably, each of the bottom walls of the connecting chamber 52 and the movable chamber 64 is provided with a connecting hole whose diameter is equal to the inner diameter of the flow channel 63 of the oil outlet pipe 12. By providing the connecting hole, the connecting chamber 52 and the movable chamber 64 can be connected to the corresponding pipe flow channel 63, thereby enabling the pipes to cooperate with each other to stably deliver lubricating oil.
[0037] Preferably, the oil storage tank 10 is provided with an oil replenishment pipe 13 that communicates with the oil storage chamber 11. The oil replenishment pipe 13 can be used to replenish lubricating oil into the oil storage chamber 11.
[0038] Example 2
[0039] Unlike Example 1, see [link to Example 1] Figure 1 and Figure 4 The flexible expansion tube 70 is a PVC transparent steel wire hose. The PVC transparent steel wire hose has elasticity and a certain degree of rigidity. When the extension tube 60 is stationary, the PVC transparent steel wire hose is compressed and positioned between the main pipe 50 and the extension tube 60. When the extension tube 60 moves, the PVC transparent steel wire hose is stretched. Due to its certain rigidity, it will not sag during stretching, thus perfectly compensating for the height difference of the flow channel 63 between the extension tube 60 and the main pipe 50 after the extension tube 60 moves.
[0040] The other structures in this embodiment are the same as those in Embodiment 1, and will not be described again here.
