Detailed Description
The invention will be further illustrated by the following examples, taken in conjunction with the accompanying drawings:

In the past, the manual liquid feeding has various defects, such as uneven smearing, inconvenient taking, easy waste and contamination, and the like, and has high operation difficulty and high labor intensity of workers, and the working efficiency and the working quality are not satisfactory. The technical scheme designs a liquid feeding mechanism and a pressing mechanism which are matched with each other to replace the traditional manual lubrication mode.
Firstly, the liquid feeding mechanism is described, the liquid feeding mechanism takes the containing container a1 as a main body, and the containing container a1 can be a cup-shaped container with an upper opening and an inner groove cavity. In order to better and more accurately take and place the oil seal, the middle part of the containing container a1 is provided with an oil seal positioning table a12, a circle of oil seal positioning table a12 is a lubrication liquid groove a11, the liquid absorbing medium a2 is placed in the lubrication liquid groove a11, and therefore, the liquid absorbing medium a2 is correspondingly hollow and annular (the shape is correspondingly changed along with the shape of the container or the shape of the lubrication liquid groove a 11). The liquid absorbing medium a2 is preferably a silica gel sponge block, because the common sponge block may have the condition that scraps fall off and pollute during the actual use process, so that the lubrication effect is adversely affected, and the silica gel sponge is effective in avoiding the problem, and although the liquid absorbing medium a2 can also select cotton clusters, absorbent towels and the like, the actual effect is not as excellent as that of the silica gel sponge. In addition, the inner groove cavity of the accommodating container a1 is divided into an oil seal positioning table a12 in the middle and a circle of lubricating liquid groove a11 surrounding the oil seal positioning table a12, so that the shape of the liquid absorbing medium a2 is correspondingly selected to be an annular body with a hollow part, and the inner ring surface of the liquid absorbing medium a2 is also the lubricating contact surface of the periphery of the oil seal. The oil seal is placed on the oil seal positioning table a12, the peripheral lubrication contact surface of the oil seal surrounds the peripheral side of the oil seal, the oil seal and the oil seal can be in a contact mode or an approaching mode, as long as the lubricating liquid stored in the oil seal can overflow and flow to the oil seal when the liquid absorbing medium a2 is extruded, the oil seal is not easy to rub with the liquid absorbing medium a2 when the pressing block b2 of the pressing mechanism is pressed down, and the approaching mode can be selected in practice.
In order to sufficiently lubricate the oil seal, the height of the liquid suction medium a2 must be higher than that of the placed oil seal, and the height of the liquid suction medium a2 after being pressed to some extent is still higher than that of the oil seal. The lubricant tank a11 can be further optimally designed, a layered design is shown in fig. 3, the lubricant tank a11 is divided into an upper half tank a111 and a lower half tank a112, the caliber of the upper half tank a111 is larger, the caliber of the lower half tank a112 is smaller, a circle of liquid absorbing medium placing edge belt a113 is formed at the juncture of the upper half tank a111 and the lower half tank a112, the liquid absorbing medium a2 can be correspondingly subjected to shape adaptation, a ring with smaller outer diameter is additionally arranged at the part of the ring, namely, the corresponding upper half ring is positioned in the upper half tank a111, and the lower half ring is positioned in the lower half tank a 112. The lower half groove a112 can provide sufficient lubricating fluid storage, and the lower half ring is matched for absorption.
In order to more conveniently and effectively supply liquid to the lubrication liquid tank a11 (namely, a mode of pouring the lubrication liquid into the storage container a1 directly is not needed), a communication channel capable of communicating the liquid to the lubrication liquid tank a11 from the outside is formed in the side wall of the storage container a1, and the communication channel can be connected with a liquid communicating pipe; or the outer wall of the containing container a1 is provided with a liquid passing connector a3, the liquid passing connector a3 is communicated with the communicating channel, and the liquid passing connector and the liquid passing pipe are externally connected with the liquid storage tank.
In other words, the pressing body b1 is a base body, a cylinder is selected in the drawing, and the pressing body b1 can be lifted by external power, for example, by a hand or by connecting pushing devices. The pressing block b2 is a core carrier, and can be integrally formed with the pressing main body b1, or can be an independent block fixedly connected (such as welding, screwing and the like) with the pressing main body b1, wherein the pressing block b2 is a hollow ring in the drawing, and the shape of the pressing block b2 is matched with that of the liquid absorbing medium a2 for better extrusion liquid outlet effect. Because the pressing block b2 is used for pressing, the pressing block b2 is definitely higher than the lower surface of the pressing main body b1, and a combined cavity formed by the hollow part of the pressing block b2 and the lower surface of the pressing main body b1 is used for preventing interference and pressing collision with an oil seal during pressing, meanwhile, the inner contour of the combined cavity can be close to and slightly larger than the oil seal, and the combined cavity can also play a role of pushing and aligning slightly when the oil seal is horizontally positioned, and in addition, an adsorption space is provided for the later-mentioned negative pressure adsorption oil seal. The thickness of the pressing block b2 is not particularly limited, that is, the pressing block b2 is higher than the pressing body b1, and may be closed or gapped with the lower surface of the pressing body b1, so that the pressing action and the subsequent negative pressure adsorption action of the pressing block b2 are not affected.
Since the pressing amount of the liquid absorbing medium a2 needs to be relatively changed for different oil seals or when a predetermined liquid outlet amount is required, but if the pressing block b2 is directly fixedly connected to the pressing body b1, the position of the pressing block b2 itself is not adjustable, and the pressing block is in rigid contact when the liquid absorbing medium a2 is pressed, the liquid absorbing medium a2 may be accompanied with a large rigid impact when being pressed, and the degree of the pressing is also difficult to control. The present solution is therefore also provided with a presser elastic floating assembly for allowing the presser b2 to move up a defined distance when it contacts the liquid absorbing medium a2 thereunder and to move back down to the original position when it is lifted off the liquid absorbing medium a2, which in some existing constructions tends to surround objects such as springs, high resilience sponge, etc.

The limit cap b6 can be a part of the upper end of the adjusting guide rod formed integrally or an independent connecting cap fixedly connected to the upper end of the adjusting guide rod. When the pressing block b2 extrudes the liquid absorbing medium a2, the pressing block b2 can move upwards due to the reaction force due to the existence of the adjusting guide rod b4, and the upward moving distance of the pressing block b2 is limited due to the existence of the adjusting spring b5, so that the pressing block b2 is buffered when the liquid absorbing medium a2 is extruded, the liquid absorbing medium a2 is extruded with proper force due to the fact that the extrusion is too fast and too strong, and the release amount of the lubricating liquid is smooth and sufficient. In addition, the extrusion degree can be finally changed by directly replacing the adjusting springs b5 with different elasticity or the adjusting guide rods b4 with different lengths, but a better adjusting mode is provided relative to the extrusion degree, namely, an external thread section is arranged on the upper part of the adjusting guide rods b4, an internal thread section is arranged on the limiting cap b6, the limiting cap b6 is simply used for fixing a nut, the limiting cap b6 is in threaded connection with the adjusting guide rods b4, and the precompression amount of the adjusting springs b5 and the height of the pressing block b2 are changed through rotation of the limiting cap b6, so that the extrusion effect of the pressing block b2 is finely adjusted finally.
