DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The core of the utility model is to provide a recovery type oil lubrication device, which can open the cover component before each lubrication through the starting component and pass the impurities on the surface of the lubricating oil into the recovery component through the driving component, so as to improve the utilization rate of the lubricating oil and improve the lubrication quality.

[0032] The present application provides a recovery type oil lubrication device, comprising: an oil lubrication tank 1, a drive assembly, a start assembly and a recovery assembly;

[0033] The oil tank 1 is a hollow component with an opening on its upper end surface. The oil tank 1 is mounted on a fixed frame 2 and contains lubricating oil. The base of the oil tank 1 can slide up and down along its inner wall. A cap assembly with a controllable opening and closing is provided at the opening of the oil tank 1.

[0034] The driving assembly is arranged on the fixed frame 2 and is located below the lubricating tank 1. The driving assembly is used to push the base of the lubricating tank 1 to slide up and down along the inner wall thereof.

[0035] The starting component is connected to the cover component and is electrically connected to the drive component. When the starting component is started, it can control the cover component to open and control the drive component to push the base to move a specified distance;

[0036] The recovery component is connected to the lubricating tank 1 and is used to recover the lubricating oil and impurities in the upper layer.

[0037] For details, please refer to the attached Figure 1 With attached Figure 5The oil tank 1 is a hollow structure with a fixed connection between its side walls and the upper end surface. The base of the oil tank 1 can move inside it along the inner surface of the side walls. An opening is provided in the middle of the upper end surface of the oil tank 1. The interior of the oil tank 1 is used to store lubricating oil, which is generally volatile and quick-drying grease. A sealing cap assembly is provided at the opening. When the sealing cap assembly is in the closed state, the oil tank 1 can be completely sealed to prevent the lubricating oil from evaporating and wasting the lubricating oil. When the sealing cap assembly is opened, the lubricating parts can be placed in the oil tank 1 for lubrication. A driving assembly is provided under the oil tank 1, and the driving assembly is fixedly connected to the base of the oil tank 1. By opening the driving assembly, the base of the oil tank 1 can be pushed up or down. Generally speaking, there is sufficient lubricating oil in the oil tank 1. When the base is pushed by the driving assembly, all the lubricating oil in the oil tank 1 can be pushed upward. In this process, impurities on the surface of the lubricating oil and some lubricating oil containing impurities can be removed. All the oil is passed into the recovery component. It should be noted that the drive component and the cover component are both connected to the starting component. The difference is that the drive component and the starting component are electrically connected, and the cover component and the starting component are mechanically connected. When the starting component is turned on, the drive component and the cover component can be turned on at the same time, that is, when the starting component is turned on, the cover component opens and the drive component is also started at the same time. The drive component can push the base upward to pass the impurities on the top of the lubricating oil into the recovery component. Generally speaking, each time the drive component is started, it pushes the base up a certain distance to avoid waste. After the lubricating oil level stabilizes, the operator puts the lubricated parts into the lubricating oil for lubrication. At this time, the impurities on the surface of the lubricating oil have been passed into the recovery component, which can ensure the lubrication quality. After lubrication is completed, the operator takes out the lubricated parts and closes the starting component. At this time, the cover component seals the opening on the surface of the oil tank to avoid lubricating oil volatilization and improve the utilization rate of the lubricating oil.

[0038] On the basis of the above embodiment, a downward extending sliding rail 3 is provided on the fixed frame 2, and the driving assembly includes a motor 4, a threaded rod 5 and a screw sleeve 6. The screw sleeve 6 is fixed to the fixed frame 2, and the motor 4 is provided on the sliding rail 3 and can slide along the sliding rail 3. The output end of the motor 4 is fixedly connected to the threaded rod 5 and the motor 4 is used to drive the threaded rod 5 to rotate on a fixed axis. The threaded rod 5 is threadedly connected to the screw sleeve 6 and the end of the threaded rod 5 is fixedly connected to the base.

[0039] For details, please refer to the attached Figure 3The oil tank 1 is arranged on the fixed frame 2, and two downward-extending sliding rails 3 are arranged on the lower surface of the fixed frame 2 through a connecting plate. The two sliding rails 3 are arranged downward in the vertical direction. A motor 4 is arranged between the two sliding rails 3. Grooves are arranged on both sides of the shell of the motor 4, and the shape and size of the grooves are adapted to the sliding rails 3 so that the motor 4 can move along the sliding rails 3. A screw sleeve 6 is also provided on the fixed frame 2. The screw sleeve 6 is an annular component, and a thread is provided on its inner circumference. The output end of the motor 4 is arranged upward and the output end of the motor 4 is connected to the lower end of the threaded rod 5. The threaded rod 5 passes through the screw sleeve 6 and is threadedly connected to the screw sleeve 6. The threaded rod 5 The upper end is connected to the base of the oil tank 1. When the motor 4 is started, it can drive the threaded rod 5 to rotate on a fixed axis. Since the screw sleeve 6 is fixed on the fixed frame 2, the motor 4 can move up or down with the rotation of the threaded rod 5. Here we only discuss the upward movement of the motor 4. During the upward movement of the motor 4, the threaded rod 5 can synchronously push the base of the oil tank 1 upward. By timing each start of the motor 4 or limiting the rotation arc of the output end of the motor 4, the upward movement distance of the motor 4 can be determined. In this embodiment, the motor 4 is limited to move up 1 mm each time it is turned on to avoid pushing too much lubricating oil into the recovery component, thereby improving the utilization rate of the lubricating oil.

[0040] Optionally, a through hole corresponding to the screw sleeve 6 is provided on the connecting plate, and the threaded hole and the through hole on the screw sleeve 6 correspond to the middle of the base of the oil tank 1 to ensure the thrust of the motor 4.

[0041] On the basis of the above embodiment, the top and the end of the sliding track 3 are both provided with motor contact switches 7 , and before and after the motor 4 contacts the motor contact switch 7 , the rotation direction of the threaded rod 5 is opposite.

[0042] For details, please refer to the attached Figure 3 3 and 4. The upper and lower maximum positions of the travel of the oil tank 1 correspond to the top and end of the sliding track 3. A motor contact switch 7 is respectively provided at the top and end of the sliding track 3. The motor 4 can contact the motor contact switch 7 when moving on the sliding track 3. During the upward movement of the motor 4, after the motor 4 completely pushes out the lubricating oil, it contacts the motor contact switch 7 on the upper side of the sliding track 3. The rotation direction of the output end of the motor 4 rotates in the opposite direction. At this time, the motor 4 will move downward. After the motor 4 returns to the motor contact switch 7 on the lower side of the sliding track 3, it rotates in the opposite direction, so that the motor 4 can move upward again. Generally speaking, when setting the program, a command for temporarily stopping the motor 4 will be added on this basis. At this time, the lubricating oil in the oil tank 1 is completely emptied and new lubricating oil needs to be added.

[0043] Based on the above embodiment, the covering assembly includes pillars 8, closing covers 9 and elastic members 10. There are four pillars 8 and four elastic members 10, and there are two closing covers 9. The four pillars 8 are distributed along the four corners of the rectangle. One closing cover 9 is connected to two pillars 8 through two elastic members 10. The elastic member 10 is in a compressed state and is used to drive the two closing covers 9 to move in opposite directions or to make the two closing covers 9 have a tendency to move in opposite directions.

[0044] Specifically, the top surface of the oil tank 1 is provided with four pillars 8, and the four pillars 8 are connected in sequence to form a rectangle, which can cover the upper end opening of the oil tank 1. An elastic member 10 is provided on each of the four pillars 8. Please refer to the attached Figure 2 Two closing covers 9 are arranged between the four pillars 8. The upper and lower ends of the left side of the closing cover 9 on the left are connected to the two pillars 8 on the left side through two elastic members 10 respectively. The upper and lower ends of the right side of the closing cover 9 on the right are connected to the two pillars 8 on the right side through two elastic members 10 respectively. It should be noted that the four elastic members 10 are all in a compressed state. The two elastic members 10 on the left can push the closing cover 9 to move to the right, and the two elastic members 10 on the right can push the closing cover to move to the left. In addition, a connecting rod is provided on each pillar 8, which can prevent the closing cover 9 from bouncing up and can play a guiding role.

[0045] Optionally, the elastic member 10 is generally a spring, which has low cost and is easy to replace.

[0046] On the basis of the above embodiment, a sealing assembly matching the shape of the opening is provided at the opening of the lubricating tank 1 , and sealing assemblies are also provided on the two closing covers 9 .

[0047] Specifically, the opening of the oil tank 1 is a circular opening, and the sealing component at the opening is an annular sealing ring, and the sealing ring is fixedly connected to the opening of the oil tank 1 and will not move with the movement of the closing cover 9. In addition, a sealing component is also provided on the two closing covers 9, but the sealing components on the two closing covers 9 are sealing strips, which are provided on the side wall of the closing cover 9 away from the elastic member 10 to ensure the sealing effect when the two closing covers 9 are in a closed state to prevent the lubricating oil from volatilizing.

[0048] Based on the above embodiment, the starting assembly includes a pedal 11, a traction rope 12 and a start button 13. The pedal 11 is a V-shaped structure. The start button 13 is arranged on the inner side of the first end of the pedal 11. There are two traction ropes 12. The first ends of the two traction ropes 12 are both arranged on the outer side of the second end of the pedal 11. The outer side of the second end of the pedal 11 is arranged toward the lubricating tank 1. The start button 13 is electrically connected to the motor 4. The second ends of the two traction ropes 12 are respectively connected to the two closing covers 9.

[0049] For details, please refer to the attached Figure 4 , a snap ring can be provided on the pedal 11 for facilitating connection with the towing rope 12. For the pedal 11, a push-button switch can also be selected. However, considering that the two towing ropes 12 need to be connected to the closing cover 9, no matter whether the push-button switch is installed above or below the lubricating oil tank 1, the operation is relatively troublesome, so it will not be discussed. However, this design is still within the protection scope of this application. The start button 13 is arranged inside the first end of the pedal 11. The first ends of the two towing ropes 12 are both arranged outside the second end of the pedal 11. The outside of the second end of the pedal 11 faces the lubricating oil tank 1. It should be noted that the pedal 11 is generally fixed on the ground directly below the lubricating oil tank 1. The two towing ropes 12 are identical in length and thickness, and the connection positions of the two towing ropes 12 with the pedal 11 are at the same height in the horizontal direction. The upper ends of the two towing ropes 12 are respectively connected to the pull rings on the sides of the two closing covers 9. When an operator steps on the pedal 11, the towing ropes 12 are pulled downward. The left towing rope 12 pulls the closing cover 9 to the left, and the right towing rope 12 pulls the closing cover 9 to the right to open the opening of the lubricating oil tank 1. In addition, the start button 13 is arranged inside the first end of the pedal 11. Each time the pedal 11 is stepped on, the second end of the pedal 11 presses on the start button 13, that is, when the closing cover 9 is opened, the start button 13 can start the motor 4 once. The output end of the motor 4 will rotate around a fixed axis by a specified angle, and push the impurities on the surface of the lubricating oil into the recovery component.

[0050] Based on the above embodiment, four rotatable fixed-axis reversing columns 14 are provided on the outer periphery of the opening of the lubricating oil tank 1. Two reversing columns 14 are respectively arranged in the two directions in which the two closing covers 9 move away from each other, and the other two reversing columns 14 are arranged at the edge of the lubricating oil tank 1.

[0051] Specifically, one reversing column 14 is respectively arranged on the left side of the left closing cover 9 and the right side of the right closing cover 9, and two reversing columns 14 are also arranged at the edge of the upper end surface of the lubricating oil tank 1. The routing of the towing rope 12 can be referred to the attached Figure 2 to avoid the towing rope 12 from rubbing against the sharp part of the support column 8 during the process of pulling the closing cover 9, and improve the service life of the towing rope 12. In addition, the reversing column 14 can rotate around a fixed axis on the upper end surface of the lubricating oil tank 1, which can also reduce the influence of friction on the service life of the towing rope 12.

[0052] Based on the above embodiment, a bracket is further provided at the edge of the upper end surface of the lubricating oil tank 1. The bracket is correspondingly arranged with the two reversing columns 14 at the edges. The bracket is an inclined U-shaped structure, and the middle part of the bracket extends outside the upper end surface of the lubricating oil tank 1.

[0053] Specifically, a bracket is provided at the position corresponding to the reversing column 14 at the edge of the upper end surface of the oil tank 1. The upper end of the bracket can extend to the outside of the upper end surface of the oil tank 1. The traction rope 12 will not generate friction with the tip of the edge of the upper end surface of the oil tank 1 during the process of pulling the closing cover 9, thereby improving the service life of the traction rope 12.

[0054] On the basis of the above embodiment, the oil tank 1 is a cylindrical structure, and its base is a piston 15 that can slide up and down along its inner wall. A sealing component is provided between the piston 15 and the inner wall of the oil tank 1.

[0055] Specifically, the piston 15 is slidably connected from the bottom of the oil tank 1 to the inside of the oil tank 1 to form the bottom wall of the oil tank, and a sealing assembly is arranged between the piston 15 and the oil tank 1. For the piston 15, the piston 15 is a cylindrical structure, so the sealing assembly uses an annular sealing ring to prevent the lubricating oil from leaking from between the piston 15 and the side wall of the oil tank 1.

[0056] Based on the above embodiment, the recovery component includes a connecting pipe 16 and a recovery tank 17 . The recovery tank 17 and the connecting pipe 16 are detachably connected. A through hole for communicating with the connecting pipe 16 is provided at the top of the side wall of the lubricating tank 1 .

[0057] Specifically, a perforation is provided at the top of the side wall of the lubricating tank 1, which is connected to a connecting pipe, and the other end of the connecting pipe is connected to a recovery tank 17. The lubricating oil with impurities discharged from the lubricating tank 1 can flow from the connecting pipe 16 into the recovery tank 17. The recovery tank 17 and the connecting pipe 16 are detachably connected. After the recovery tank 17 is filled, it is sealed and stored, and then uniformly processed to avoid polluting the environment.

[0058] Optionally, the recovery tank 17 is generally a transparent tank, which is convenient for the operator to visually see the remaining capacity inside and to facilitate timely replacement of the recovery tank 17.

[0059] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0060] The above describes in detail the oil recovery device provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is intended only to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications fall within the scope of protection of the claims of the present invention.
