The control device and the liquid pump are both installed inside the workbench. The liquid pump is used to transport the lubricating oil, which is transported to the filling tube through a flexible oil pipeline. The fixed fixture is used to fix the container, and the filling tube is pushed into the container by the electric push rod, and then the oil pump is started to complete the filling.
[0004] However, when filling lubricating oil, the mouth of some containers is small, which causes the inner diameter of the filling tube to be reduced accordingly. As a result, after the oil pipeline is closed, the lubricating oil in the filling tube is not easy to fall under atmospheric pressure. After it is drawn out, it is easy to cause the lubricating oil in the filling tube to drip due to vibration or inertia, thereby causing pollution to the workbench. Therefore, a lubricating oil filling equipment is proposed to address the above problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Specific examples are given below.
[0023] See also Figure 1-3As shown, a lubricating oil filling equipment comprises a workbench body 11; an electric push rod 13 is fixedly connected to the top side wall of the workbench body 11; a fixing fixture 12 is fixedly connected to the workbench body 11; a bracket is fixedly connected to the output end of the electric push rod 13; a filling tube 14 is fixedly connected to the bottom of the bracket; a hose 16 is provided on the top of the filling tube 14; a piston cylinder 17 is fixedly connected to the top of the hose 16; the piston cylinder 17 is fixedly connected to the bracket; a piston rod 18 is slidably connected to the inside of the piston cylinder 17; an air intake pipe 191 is fixedly connected to the side of the piston cylinder 17; an adjusting seat 19 is provided at the top of the workbench body 11 corresponding to the piston rod 18; an oil delivery pipe 15 is fixedly connected to the side of the filling tube 14; when in use, when the filling tube 14 is taken out of the container, After being pulled out, the electric push rod 13 pulls the bracket, piston cylinder 17, piston rod 18 and filling tube 14 upward. During the upward movement, the top of the piston rod 18 contacts the adjusting seat 19. As it continues to move upward, the adjusting seat 19 is fixed and the piston rod 18 is pushed downward, so that the gas in the piston cylinder 17 is injected into the filling tube 14 through the hose 16. By injecting gas from the top of the filling tube 14, the blending lubricating oil in the filling tube 14 can be injected into the container, thereby reducing the dripping of the blending lubricating oil in the filling tube 14 after the filling is completed, thereby reducing the contamination of the workbench body 11. The diameter of the air inlet pipe 191 is smaller than the hose 16, and the oil delivery pipe 15 is used to connect to the liquid pump inside the workbench body 11 to transport the blending lubricating oil.
[0024] Further, such as Figure 3 As shown, the top of the filling tube 14 is connected to a top cover 21 through a thread; the top of the top cover 21 is fixedly connected to the end of the hose 16; the inner wall of the top cover 21 is fixedly connected to a valve body 22 which is fixedly connected to the inner wall of the air inlet pipe 191; an oil hole is opened in the middle of the valve body 22; a sealing cavity 24 is opened in the middle of the oil hole; an elastic member is fixedly connected to the inner wall of the sealing cavity 24; a sealing seat 23 is fixedly connected to the end of the elastic member; when the piston rod 18 moves downward, the airflow in the valve seat in the top cover 21 will push the sealing seat 2 3 moves downward, the elastic member is compressed, and the gas enters the interior of the filling tube 14. The sealing seat 23 in the valve seat in the intake pipe 191 is fitted with the oil hole for sealing, so that the gas is not easy to flow out of the intake pipe 191, and plays a role of one-way flow. The top cover 21 and the filling tube 14 are connected by threads. Relying on the detachable structure design, the hose 16 can be easily installed. When filling and blending lubricating oil, the sealing seat 23 on the filling top is sealed, so that the filled blending lubricating oil is not easy to enter the interior of the piston cylinder 17.
[0025] Further, such as Figure 2As shown, one end of the air intake pipe 191 away from the piston cylinder 17 is connected to the filter seat 31 through a thread; the middle part of the filter seat 31 is fixedly connected to the filter screen 32; when in use, the staff can screw the filter seat 31 onto the air intake pipe 191 by rotating, and the air sucked into the air intake pipe 191 can be filtered by the filter screen 32, so as to reduce the external dust and foreign matter from entering the interior of the piston cylinder 17 and causing blockage.
[0026] Furthermore, a screw sleeve 41 is fixedly connected to the top of the workbench body 11 ; a screw rod 42 is threadedly connected to the middle of the screw sleeve 41 ; and a bottom end of the screw rod 42 is fixedly connected to the adjustment seat 19 .
[0027] During use, when it is necessary to fill containers of different heights, the lifting height of the filling tube 14 will also be adjusted accordingly. Then the staff can rotate the screw 42 to move the screw 42 and the adjustment seat 19 downward, so as to adjust the position of the adjustment seat 19, so that when the filling tube 14 is pulled out, the adjustment seat 19 can contact the top of the piston rod 18.
[0028] Further, such as Figure 2 As shown, a rubber sleeve 52 is fixedly connected between the top of the piston cylinder 17 and the piston rod 18; a spring 51 is fixedly connected between the piston cylinder 17 and the piston rod 18; the spring 51 is located inside the rubber sleeve 52; when in use, the spring 51 is used to facilitate the automatic resetting of the piston rod 18, and the rubber sleeve 52 is used to cover the surface of the piston rod 18, so as to reduce the adhesion of external dust and foreign matter to the piston rod 18, thereby playing a dust-proof role.
[0029] Further, such as Figure 2-4 As shown, a connecting seat 61 is fixedly connected to the top of the filling tube 14; an outer air guide seat 62 is slidably connected to the middle of the connecting seat 61; an inner air guide seat 63 is slidably connected to the middle of the outer air guide seat 62; during installation, the staff inserts the outer air guide seat 62 into the middle of the connecting seat 61, and then inserts the inner air guide seat 63 to connect the outer air guide seat 62 and the inner air guide seat 63. There is a certain gap between the inner air guide seat 63 and the outer air guide seat 62, and the air flow is ejected from the gap. The gap has a certain inclination arc, which corresponds to the bottom direction of the filling tube 14, so that the air flow is ejected to the bottom of the filling tube 14 to purge it, thereby pushing the lubricating oil on the inner wall at the bottom of the filling tube 14 to drip and reduce the residual lubricating oil.
[0030] Further, such as Figure 3As shown, a sealing ring 7 is fixedly connected to the inner side wall of the top cover 21. When in use, the sealing ring 7 is provided, so that the connection between the top cover 21 and the filling tube 14 can be sealed to reduce gas leakage. Working principle: when in use, after the filling tube 14 is drawn out of the container, the electric push rod 13 pulls the bracket, the piston cylinder 17, the piston rod 18 and the filling tube 14 to move upward. During the upward movement, the top of the piston rod 18 contacts the adjustment seat 19. As it continues to move upward, the adjustment seat 19 is fixed and the piston rod 18 is pushed downward, so that the gas in the piston cylinder 17 is injected into the filling tube 14 through the hose 16. By injecting gas from the top of the filling tube 14, the blended lubricating oil in the filling tube 14 can be injected into the container. Thereby, the dripping of the blending lubricating oil in the filling tube 14 after the filling is completed can be reduced, thereby reducing the contamination of the workbench body 11. The diameter of the air inlet pipe 191 is smaller than the hose 16. The oil delivery pipe 15 is used to connect with the liquid pump inside the workbench body 11 to deliver the blending lubricating oil. The airflow in the valve seat in the top cover 21 will push the sealing seat 23 downward, the elastic member is compressed, and the gas enters the interior of the filling tube 14. The sealing seat 23 in the valve seat in the air inlet pipe 191 fits with the oil hole for sealing, making it difficult for the gas to flow out of the air inlet pipe 191, thereby playing a one-way flow role. The top cover 21 and the filling tube 14 are connected by threads. Relying on the detachable structure design, the hose 16 can be easily installed, and the blending lubricating oil can be filled. When filling, the sealing seat 23 at the top of the filling is sealed, so that the filled blended lubricating oil is not easy to enter the interior of the piston cylinder 17. The staff can screw the filter seat 31 onto the intake pipe 191 by rotation, and rely on the filter screen 32 to filter the air sucked into the intake pipe 191, so as to reduce the external dust and foreign matter from entering the interior of the piston cylinder 17 and causing blockage. When it is necessary to fill containers of different heights, the lifting height of the filling tube 14 will also be adjusted accordingly. Then, the staff can rotate the screw 42 to move the screw 42 and the adjusting seat 19 downward, so as to adjust the position of the adjusting seat 19, so that when the filling tube 14 is pulled out, the adjusting seat 19 can contact with the top of the piston rod 18, and the spring 5 1 is used to facilitate the automatic resetting of the piston rod 18. The rubber sleeve 52 is used to cover the surface of the piston rod 18, so as to reduce the adhesion of external dust and foreign matter to the piston rod 18, and play a role in dust prevention. During installation, the staff inserts the outer air guide seat 62 into the middle of the connecting seat 61, and then inserts the inner air guide seat 63 to connect the outer air guide seat 62 and the inner air guide seat 63. There is a certain gap between the inner air guide seat 63 and the outer air guide seat 62, and the air flow is ejected from the gap. The gap has a certain inclination arc, which corresponds to the bottom direction of the filling tube 14, so that the air flow is ejected to the bottom of the filling tube 14 to purge it, thereby promoting the lubricating oil on the inner wall of the bottom of the filling tube 14 to drip and reduce the residual lubricating oil.
