[0002] A lubrication pump is a lubrication device that supplies lubricant to the lubrication parts. Mechanical equipment requires regular lubrication. In the past, the main method of lubrication was manual lubrication after a certain maintenance cycle based on the working condition of the equipment. A lubrication pump can make this maintenance work easier. Lubrication pumps are divided into manual lubrication pumps and electric lubrication pumps.

[0003] The Chinese patent with the authorization announcement number CN114923105A discloses a centralized lubrication pump, including an oil storage tank with a base on the bottom surface and an upper cover on the top surface, an oil pressure plate sealed with the inner wall of the oil storage tank, a spring mechanism connected with the upper cover at the upper end and the oil pressure plate at the lower end, a rotating device installed on the base and located inside the oil storage tank, a rotating arm fixedly connected with the rotating device, a stirring rod fixedly connected with the rotating arm at the lower end and rotatably connected with the oil pressure plate at the upper end, an output shaft connected with the rotating device and a motor for driving the rotating device to rotate, the stirring rod is a telescopic rod, and the upper cover has a vent. The centralized lubrication pump effectively solves the problems of insufficient stirring of grease and easy contamination of grease by the stirring rod of fixed length set in the grease tank.

[0004] With respect to the above-mentioned related technologies, the oil storage tank is usually made of opaque material, which makes it inconvenient for operators to obtain the liquid level of the lubricating oil in the oil storage barrel, and thus it is impossible to replenish the lubricating oil in the oil storage barrel in time. Utility Model Content

[0005] In order to facilitate operators to obtain the liquid level of the lubricating oil in the oil storage barrel and replenish the lubricating oil in time, the present application provides a lubrication pump that is easy to detect the liquid level.

[0006] The present application provides a lubrication pump that is convenient for detecting liquid level and adopts the following technical solution:

[0007] The top of the oil pump is connected with the oil pump, and the bottom of the oil pump is connected with the oil pump end. The oil pump end is connected with the oil pump end at the oil pump end. The oil pump end is connected with the oil pump end at the oil pump end.

[0008] By adopting the above technical solution, when the lubricating oil level in the oil storage barrel gradually decreases, the oil pressure plate follows the drop in the level, the first magnetic block follows the movement of the oil pressure plate, and the first magnetic block and the first magnetic ring attract each other, the first magnetic block drives the first magnetic ring to move, and the first magnetic ring is slidably connected to the support rod along the length direction of the support rod, and the liquid level of the lubricating oil in the oil storage barrel is obtained by observing the position of the first magnetic ring, so that the operator can replenish the lubricating oil in the oil storage barrel in time.

[0009] Optionally, a limit rod is connected inside the oil storage barrel, the length direction of the limit rod is consistent with the length direction of the oil storage barrel, the oil pressure plate is slidably sleeved on the limit rod, and the oil pressure plate is slidably connected to the limit rod along the length direction of the oil storage barrel.

[0010] By adopting the above technical solution, when the oil pressure plate is slidably connected to the oil storage barrel along the length direction of the oil storage barrel, the oil pressure plate is slidably connected to the limit rod along the length direction of the oil storage barrel, so that the oil pressure plate can move stably in a predetermined direction.

[0011] Optionally, the support rod sleeve is provided with a protective tube, the central axis of the protective tube is consistent with the central axis of the support rod, a movable gap for placing the first magnetic ring is provided between the support rod and the inner wall of the protective tube, the protective tube is made of transparent material, and the circumference of the first magnetic ring is in contact with the inner wall of the protective tube.

[0012] By adopting the above technical solution and adding a protective tube, the situation in which the first magnetic ring is damaged by external force impact is reduced, and the inner ring of the first magnetic ring is in contact with the support rod, and the outer ring of the first magnetic ring is in contact with the inner wall of the protective tube. Even if the first magnetic ring is broken, the first magnetic ring can still move with the first magnetic block.

[0013] Optionally, the elastic member is a spring arrangement, and the spring is sleeved on the limiting rod. Two springs are provided, and the length direction of the spring is consistent with the length direction of the limiting rod. The two springs are distributed in sequence along the length direction of the limiting rod. The top end of one spring is connected to the bottom of the cover plate, and the bottom end of the other spring is connected to the oil pressure plate. The two springs are connected at one end close to each other. When the oil pressure plate and the cover plate are close to each other, the springs are squeezed and deformed.

[0014] By adopting the above technical solution, when the oil storage barrel is full of lubricating oil, the oil pressure plate and the cover plate approach each other, and the oil pressure plate squeezes the spring and drives the spring to deform.

The installation sleeve is slidably connected to the limiting rod along the length direction of the limiting rod. The two springs are respectively connected to the two ends of the installation sleeve along the length direction of the limiting rod, and the end of the spring with a smaller diameter is connected to the installation sleeve.

[0018] By adopting the above technical solution, when the liquid level in the oil storage barrel gradually rises, the oil pressure plate moves along the length direction of the limit rod and gradually approaches the cover plate, the spring is squeezed and deformed, and the spring drives the mounting sleeve to move along the length direction of the limit rod.

[0021] Optionally, the protection tube is provided with scale lines, and the scale lines are used to reflect the liquid level in the oil storage barrel.

[0022] By adopting the above technical solution and adding scale lines, the specific amount of remaining oil in the oil storage barrel can be obtained through the position of the first magnetic ring, which is convenient for operators to observe.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a lubrication pump that is convenient for detecting liquid level. Figure 1 and Figure 2A lubrication pump for convenient liquid level detection includes a base 100 and an oil storage barrel 200. The oil storage barrel 200 is connected to the top of the base 100 and is vertically arranged. An oil pressure plate 210 is arranged in the oil storage barrel 200. The oil pressure plate 210 is arranged on the surface of the lubricating oil. An exhaust hole 250 is opened on the side wall of the oil storage barrel 200. The exhaust hole 250 is arranged above the oil pressure plate 210. The central axis of the oil pressure plate 210 is colinear with the central axis of the oil storage barrel 200. The oil pressure plate 210 is slidably connected to the oil storage barrel 200 in the vertical direction, and the circumference of the oil pressure plate 210 is in contact with the inner wall of the oil storage barrel 200. A support rod 110 is provided on one side of the oil storage barrel 200. The length direction of the support rod 110 is consistent with the vertical direction. The first magnetic ring 111 is provided on the sliding sleeve of the support rod 110. The central axis of the first magnetic ring 111 is collinear with the central axis of the support rod 110. The first magnetic ring 111 is slidably connected to the support rod 110 along the vertical direction. A first magnetic block 211 is provided on the circumferential side of the oil pressure plate 210. The first magnetic block 211 is annular. The central axis of the first magnetic block 211 is collinear with the central axis of the oil pressure plate 210. The first magnetic block 211 and the first magnetic ring 111 attract each other. When the liquid level gradually decreases, the oil pressure plate 210 follows the liquid level to decrease, the first magnetic block 211 moves with the oil pressure plate 210, and the first magnetic block 211 drives the first magnetic ring 111 to move. The operator obtains the liquid level of the lubricating oil in the oil storage barrel 200 through the position of the first magnetic ring 111.

[0034] Reference Figure 1 and Figure 2 The top of the oil storage barrel 200 is open, and a cover plate 220 is connected to the top of the oil storage barrel 200. The central axis of the cover plate 220 is in line with the central axis of the oil storage barrel 200. The cover plate 220 covers the top opening of the oil storage barrel 200. The support rod 110 is connected to the cover plate 220 and the base 100 at both ends along its length direction. The base 100 is also connected to three mounting rods 120, and the length direction of the mounting rod 120 is consistent with the vertical direction. The support rod 110 and the three mounting rods 120 are distributed at intervals on the top of the base 100 along the circumference of the oil storage barrel 200. The bottom end of the mounting rod 120 is connected to the base 100, and the top end of the mounting rod 120 is connected to the cover plate 220.

[0035] Reference Figure 2 and Figure 3, a limit rod 230 is connected inside the oil storage barrel 200, the length direction of the limit rod 230 is consistent with the vertical direction, the central axis of the limit rod 230 is in line with the central axis of the oil storage barrel 200, the oil pressure plate 210 is slidably sleeved on the limit rod 230, and the oil pressure plate 210 is slidably connected to the limit rod 230 along the vertical direction. The oil pressure plate 210 is sleeved with a seal 212, and there are two seals 212. The two seals 212 are arranged in sequence along the vertical direction. The seal 212 is a leather cup seal ring, and the first magnetic block 211 is arranged between the two seals 212. The seal 212 contacts the inner wall of the oil storage barrel 200, and the seal 212 is used to seal the gap between the oil pressure plate 210 and the inner wall of the oil storage barrel 200. The limit rod 230 is added to make the oil pressure plate 210 move stably along a predetermined direction.

[0036] Reference Figure 2 The oil storage barrel 200 is connected with an elastic member, which is used to drive the oil pressure plate 210 to slide along the length direction of the oil storage barrel 200 and be connected in the oil storage barrel 200. The elastic member is a spring 240, which is a conical spring. There are two springs 240, and the length direction of the spring 240 is consistent with the vertical direction. The two springs 240 are distributed in sequence along the vertical direction. The spring 240 is sleeved on the limit rod 230. The limit rod 230 sliding sleeve is provided with an installation sleeve 231, the central axis of the installation sleeve 231 is colinear with the central axis of the limit rod 230, and the installation sleeve 231 is arranged between the two springs 240.

[0037] Reference Figure 2 , the two springs 240 with smaller diameters are close to each other, and the two springs 240 are respectively connected to the mounting sleeve 231 at both ends in the vertical direction, one spring 240 with a larger diameter is connected to the bottom of the cover plate 220, and the other spring 240 with a larger diameter is connected to the top of the oil pressure plate 210. When the oil pressure plate 210 and the cover plate 220 are close to each other, the spring 240 is squeezed and deformed. When there is more lubricating oil in the oil storage barrel 200, the oil pressure plate 210 and the cover plate 220 are close to each other, causing the spring 240 to deform. When the liquid level gradually drops, the spring 240 restores its shape and pushes the oil pressure plate 210 to move downward in the vertical direction, so that the spring 240 moves downward stably.

[0038] Reference Figure 1 and Figure 4The support rod 110 is sleeved with a protective tube 112, the length direction of the protective tube 112 is consistent with the vertical direction, the central axis of the protective tube 112 is consistent with the central axis of the support rod 110, and the two ends of the protective tube 112 along its length direction are respectively connected to the cover plate 220 and the base 100. A moving gap 114 for placing the first magnetic ring 111 is provided between the support rod 110 and the inner wall of the protective tube 112. The first magnetic ring 111 is slidably connected in the moving gap 114 along the vertical direction, and the circumference of the first magnetic ring 111 is in contact with the inner wall of the protective tube 112. The protective tube 112 is made of transparent plastic material, and the protective tube 112 is provided with a scale line 113, which extends upward from the bottom end of the protective tube 112, and the scale line 113 is used to reflect the liquid level in the oil storage barrel 200. The scale line 113 is added to facilitate the operator to obtain the remaining oil in the oil storage barrel 200.

[0039] The implementation principle of a lubrication pump that is convenient for detecting the liquid level in an embodiment of the present application is as follows: when the oil level in the oil storage barrel 200 is high, the oil pressure plate 210 and the cover plate 220 approach each other, the oil pressure plate 210 and the cover plate 220 squeeze the spring 240, and cause the spring 240 to deform. When the liquid level gradually drops, the spring 240 gradually restores its shape and pushes the oil pressure plate 210 to slide downward in the vertical direction and connect to the oil storage barrel 200. The first magnetic block 211 moves with the oil pressure plate 210, and the first magnetic block 211 drives the first magnetic ring 111 to move. The first magnetic ring 111 slides downward in the vertical direction and is connected to the moving gap 114. The operator obtains the liquid level of the lubricating oil in the oil storage barrel 200 through the position of the first magnetic ring 111, thereby making it more convenient to read the liquid level and facilitating the operator to replenish the lubricating oil into the oil storage barrel 200 in time.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
