The process of adding lubricants requires manual disassembly, adding and reassembly, which is inefficient and affects production. Therefore, automatic lubricant adding devices are born. However, in actual use, this device often fails to flow to the designated position through the automatic adding device due to the inappropriate suction pressure of the device or the lubricant is too thick and viscous, and the lubricant cannot achieve the lubrication effect. Therefore, a corresponding auxiliary extrusion device is needed to solve this kind of problem.

The lubricant extrusion device opens the suction connection valve, and then the extrusion spring squeezes the pad, so that the pad squeezes the lubricant storage squeeze bottle, and then the lubricant in the lubricant storage squeeze bottle is discharged from the inside of the lubricant storage squeeze bottle through the suction connection valve, thereby squeezing the lubricant, facilitating automatic spraying of the lubricant, preventing the lubricant from being too viscous to be squeezed out, improving the convenience of lubricant spraying, and facilitating the transportation of the lubricant to a designated location through the connecting tube on the suction connection valve, thereby improving the convenience of adding lubricant.

When it is needed to be sprayed out through the nozzle 3, the pressure button 61 can be pressed, and the pressure rod 62 pushes the pressure cover 63 downward. The pressure of the pressure cover 63 on the top inclined surface of the wedge block 82 can make the wedge block 82 flip outward, and then under the push of the first spring 10, the wedge block 82 automatically separates from the conical block 92, and the elastic force of the first spring 10 is used to release the lubricant. Under the action of the pressure, the pressing plate 51 is automatically pushed downward to compress the squeeze bottle 7, and the movable plug 13 in the connecting valve 2 moves downward due to the pressure, so that the conical plug 133 closes the bottom of the movable cavity 21, and at the same time, the cylindrical plug 132 moves downward to open the through hole 22, so that the lubricant in the squeeze bottle 7 can enter the movable cavity 21 above the cylindrical plug 132 through the guide tube 131 and the second guide hole 135 on the guide tube 131, and then pass to the nozzle 3 through the through hole 22, and finally be sprayed out through the nozzle 3;

[0032] When lubricant needs to be added to the squeeze bottle 7, the push plates 52 on both sides of the pressure plate 51 can be pulled upward by overcoming the elastic force of the first spring 10, so that the squeeze bottle 7 is in a stretched state. During this process, the movable plug 13 moves upward under the action of air pressure, and the through hole 22 is closed by the cylindrical plug 132. At the same time, the conical plug 133 opens the bottom of the movable cavity 21, so that the lubricant can be sucked into the movable cavity 21 below the cylindrical plug 132 through the suction nozzle 4, and then enters the guide tube 131 through the first guide hole 134, and then is introduced into the squeeze bottle 7 by the guide tube 131, and the squeeze bottle 7 is filled with lubricant until the wedge block 82 is clamped on the conical block 92, so that the first spring 10 and the second spring 11 are re-accumulated.
