[0022] Example 1
[0023] like Figures 1 to 4As shown in the figure, this embodiment proposes an automatic return oil pump, which includes a connecting plate 1. A base 2 is fixedly connected to the outside of the connecting plate 1. A pump head 3 is fixedly connected to the upper part of the connecting plate 1. A connecting wheel 4 is inlaid on the outer surface of the connecting plate 1. A pump head connecting piece 5 and a handle 6 are successively hinged on the outer surface of the connecting wheel 4.

[0024] In this embodiment, referring to Figures 1 to 3 , the setting of the connecting wheel 4 and the pump head connecting piece 5 can facilitate the manual movement of the handle 6 and limit the movement of the handle 6. Thus, the first telescopic spring 8 can provide a pulling force to reset the pulled handle 6, which is convenient for retracting the handle 6 and avoiding the situation that the handle 6 is exposed outside and collides with the staff, affecting the normal operation of the device.
[0025] A piston 7 is installed inside the pump head 3, and the output end of the piston 7 is hinged to the inner wall of the handle 6. By setting the piston 7, the staff can manually move the handle 6 to pull the piston 7 to perform piston movement. And the piston 7 is connected to a one-way oil inlet valve 13, which can better facilitate the creation of a vacuum inside the pump head 3, and then facilitate the extraction of the lubricating oil in the fuel tank 11 and the discharge of the lubricating oil to the equipment that needs lubrication through the one-way oil inlet valve 13.
[0026] An installation head 10 for installing or disassembling the fuel tank 11 is provided on the outer surface of the pump head 3. An installation hole 12 for installing or disassembling the base 2 is opened on the outer surface of the base 2. By setting the installation head 10, it is convenient to install the fuel tank 11 into the installation head 10, and the fuel tank 11 is connected to the installation head 10, which is convenient for pouring the lubricating oil in the fuel tank 11 into the whole device, and then the lubricating oil can be discharged through the discharge component and applied to the area that needs lubrication on the mechanical equipment.
[0027] A one-way oil inlet valve 13 and an exhaust valve 14 are fixedly connected to the outside of the pump head 3. The one-way oil inlet valve 13 and the exhaust valve 14 are respectively used for oil inlet and exhaust; a one-way oil outlet valve 15 communicating with the pump head 3 is provided on the outer surface of the connecting plate 1, and the one-way oil outlet valve 15 is used for the outlet of the lubricating oil.
[0028] By setting the one-way oil inlet valve 13 and the exhaust valve 14, it is convenient to discharge the lubricating oil through the one-way oil inlet valve 13. And the one-way oil inlet valve 13 is set as a one-way valve, which can better discharge the lubricating oil and avoid the situation of oil backflow.

[0029] Embodiment 2
[0030] As Figures 1 to 4 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that the upper part of the connecting plate 1 is provided with a fuel tank 11, and the upper surface of the base 2 is provided with a clamping mechanism 9 for stably clamping the fuel tank 11.
[0031] In this embodiment, referring to Figures 1 to 4 , the setting of the clamping mechanism 9 can facilitate the stable clamping of the fuel tank 11, avoid the situation of loosening and falling off of the fuel tank 11 after multiple installations or disassembly and maintenance, greatly improve the stability of the fuel tank 11 installed on the overall device, and greatly improve the practicality of the overall device.
[0032] The clamping mechanism 9 includes a fixed block 901 fixedly connected to the upper surface of the base 2, and a sliding rod 902 fixedly connected to the outer surface of the fixed block 901; a slidable sliding cylinder 903 is sleeved on the outer surface of the sliding rod 902, and a second telescopic spring 904 sleeved on the outer surface of the sliding rod 902 and connected to the fixed block 901 and the sliding cylinder 903, and the sliding cylinder 903 is used for stably clamping the fuel tank 11.
[0033] By setting the sliding cylinder 903, the sliding cylinder 903 can slide in the sliding rod 902, so that the elastic force of the second telescopic spring 904 can be used to push the sliding cylinder 903 to slide in the sliding rod 902, and then drive the subsequent components through the sliding cylinder 903 to stably clamp the fuel tank 11, avoiding the situation of unstable installation and slipping of the fuel tank 11 after multiple installations or disassembly and maintenance.
[0034] The clamping mechanism 9 further includes a clamping plate 905 connected to the sliding cylinder 903 and in contact with the opening end of the fuel tank 11. The outer surface of the clamping plate 905 is provided with anti-slip lines. The clamping plate 905 is used for stably clamping the fuel tank 11. By setting the clamping plate 905, the fuel tank 11 can be better stably clamped, and the anti-slip lines provided on the surface of the clamping plate 905 can further improve the clamping stability of the fuel tank 11, greatly improve the stability of the fuel tank 11, and avoid the situation of the fuel tank 11 falling off during use.
[0035] The clamping mechanism 9 further includes a limiting plate 907 fixed to the outer surface of the sliding cylinder 903, and a limiting rod 906 connected to the base 2 and slidably engaged with the limiting plate 907. The limiting rod 906 and the limiting plate 907 are used to stabilize the lateral movement of the sliding cylinder 903. By providing the limiting rod 906, the limiting rod 906 can better facilitate the limiting sliding of the limiting plate 907, thereby avoiding the situation that the sliding cylinder 903 rotates when sliding in the sliding rod 902, and further avoiding the rotation deviation when the fuel tank 11 is clamped stably, which affects the clamping effect of the fuel tank 11.
[0036] A retaining ring 908 is fixedly connected to the end of the limiting rod 906 away from the limiting plate 907. The retaining ring 908 is used to limit and block the limiting plate 907. By providing the retaining ring 908, the retaining ring 908 can better limit and block the limiting plate 907, thereby avoiding the risk that the limiting plate 907 and the sliding cylinder 903 fall off during sliding, and thus greatly improving the stability and practicality of the overall device.
[0037] Working principle: First, install the fuel tank 11 on the mounting head 10. The base 2 is used to fix the whole device on the machine that needs lubricant through the mounting holes 12. The external lubricating oil liquid enters the fuel tank 11 for storage through the one-way oil inlet valve 13, and the one-way oil inlet valve 13 is connected to the external lubricating oil equipment, and the one-way oil outlet valve 15 is connected to the mechanical equipment that needs lubrication. When the mechanical equipment needs lubrication, the user pulls the handle 6, and the handle 6 drives the piston 7 to move outwards. Since the piston 7 is connected to the one-way oil inlet valve 13, pulling the piston 7 makes the pipeline in the pump head 3 vacuum, and the lubricating oil in the fuel tank 11 will be discharged along the one-way oil outlet valve 15 and enter the mechanical equipment that needs lubrication. The first telescopic spring 8 can facilitate the return of the handle 6, thereby facilitating the retraction of the handle 6. The setting of the clamping mechanism 9 can facilitate the extrusion and clamping of the fuel tank 11, effectively avoiding the situation that the fuel tank 11 loosens and falls off.
