DETAILED DESCRIPTION
[0022] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of 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.
[0023] See also Figure 1-Figure 7 The utility model provides a technical solution: a flange with an oil filling mechanism, comprising a flange body 1, an outer ring surface of the flange body 1 is provided with an oil storage tank 2 for containing lubricating oil, a sealing plate 3 is fixed inside the oil storage tank 2, an inner ring surface of the flange body 1 is provided with an oil unloading hole 5, the oil unloading hole 5 is connected to the oil storage tank 2, a connecting block 10 is plugged into the top of the oil storage tank 2, a guide rod 8 is fixed to the bottom end of the connecting block 10, the guide rod 8 passes through the sealing plate 3 and is fixed to the surface of the connecting piece 7, a sealing head 6 is fixed to the bottom surface of the connecting piece 7 for blocking the oil unloading hole 5, an oil filling hole 4 is provided on the surface of the sealing plate 3, a through hole 11 is provided on the surface of the connecting block 10, and the through hole 11 corresponds to the oil filling hole 4.
[0024] The distance between the sealing plate 3 and the notch of the oil storage tank 2 is equal to the height of the connecting block 10. Rubber clamps are fixed on both sides of the connecting block 10. After the connecting block 10 is inserted into the oil storage tank 2, the rubber clamps are clamped between the connecting block 10 and the oil storage tank 2 to produce elastic deformation. After the connecting block 10 is inserted into the oil storage tank 2, the existence of the rubber clamps prevents the connecting block 10 from bumping in the oil storage tank 2. The top surface of the connecting block 10 is screwed with a hand screw 17, which penetrates the connecting block 10 and is screwed to the top surface of the sealing plate 3. The reason for this is that A hand-tightened screw 17 is installed on the block 10 to reinforce the connection block 10 to be installed in the oil storage tank 2; the bottom surface of the oil storage tank 2 is an arc-shaped curved surface, and the bottom surface of the oil storage tank 2 protrudes upward from both sides to the center. The connecting piece 7 is an arc-shaped piece, and the width of the connecting piece 7 is smaller than the bottom width of the oil storage tank 2. The top end of the guide rod 8 passes through the through hole 9, and the through hole 9 is provided on the surface of the sealing plate 3; the lubricating oil contained in the inside of the oil storage tank 2 is guided to both sides along the bottom surface, and when the head 6 is lifted and pulled away from the oil unloading hole 5, the lubricating oil flows out through the oil unloading hole 5.
[0025] A rubber plug block 12 is fixed inside the through hole 11, and a plug head is integrally formed at the bottom end of the rubber plug block 12, and the plug head is spherical in structure. After the connecting block 10 is inserted into the oil storage tank 2, the plug head is plugged into the oil filling hole 4, and the diameter of the plug head is larger than the aperture of the oil filling hole 4; a pick-out groove 13 is provided on the top surface of the connecting block 10, and the pick-out groove 13 is an "L"-shaped groove. There are two pick-out grooves 13, and the two pick-out grooves 13 are symmetrically distributed about the through hole 11, and a pressure relief hole 14 is provided on the bottom surface of the pick-out groove 13; a non-woven fabric sheet 15 is fixed to the bottom surface of the pick-out groove 13, and a rubber gasket 16 is fixed to the top surface of the sealing plate 3. After the connecting block 10 is plugged into the oil storage tank 2, the connecting block 10 squeezes the rubber gasket 16, and the rubber gasket 16 blocks the bottom end of the pressure relief hole 14; it should be noted that the rubber plug The diameter of the spherical structure at the bottom of the block 12 is smaller than the height of the head 6. When it is necessary to add lubricating oil to the inside of the oil storage tank 2, the connecting block 10 is lifted up a short distance, and the connecting block 10 drives the bottom end of the rubber plug block 12 to be pulled out from the oil filling hole 4. At this time, the bottom end of the head 6 is still plugged into the top of the oil unloading hole 5. After the lubricating oil is sucked out through the needle tube, the needle penetrates the rubber plug block 12, and the lubricating oil is injected into the oil storage tank 2 through the oil filling hole 4. At this time, the oil filling hole 4 and the pressure relief hole 14 are depressurized to ensure that the lubricating oil can be injected into the oil storage tank 2; after the lubricating oil is replenished, the connecting block 10 is pushed down, the rubber plug block 12 blocks the oil filling hole 4, and the bottom end of the pressure relief hole 14 is blocked by the rubber gasket 16. The hand-tightening screw 17 is screwed on the sealing plate 3 to prevent the connecting block 10 from falling off from the oil storage tank 2.
[0026] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
