Description

Technical Field

[0001] The utility model relates to the technical field of oil pans, in particular to an oil pan capable of quickly draining oil. Background Art

[0002] The oil pan is the lower half of the crankcase, also known as the lower crankcase. Its function is to seal the crankcase as the outer shell of the oil storage tank to prevent impurities from entering, and to collect and store the lubricating oil flowing back from the friction surfaces of the diesel engine, dissipate some heat, and prevent the lubricating oil from oxidizing.

[0003] The oil pan serves as the outer shell of the oil storage tank, and its sealing effect is usually relatively good. Therefore, during the oil draining process, the air pressure inside the oil pan will be lower than the external atmospheric pressure, resulting in the phenomenon of oil outflow and air inflow during the oil draining process, which causes the flow rate of the lubricating oil to be too slow, making the oil draining process very slow and affecting maintenance efficiency.

[0007] A spring, the spring being sleeved on the outer wall of the sliding tube, one end of the spring being fixedly mounted on the bottom of the bracket, and the other end of the spring being fixedly mounted on the top of the limit block. The limit block is provided in conjunction with the spring to push the sliding tube out of the oil pan body;

[0008] The conical block is fixedly installed at the bottom of the sliding tube. By setting the conical block, the lubricating oil released from the oil drain hole can be guided to the surroundings of the sliding tube to prevent the lubricating oil from blocking the bottom of the sliding tube, which is beneficial to the air circulation inside and outside the oil pan body.

[0009] Preferably, the cleaning mechanism includes a connecting rod, and the connecting rod is fixedly mounted on the side wall of the limiting block.

[0010] Preferably, a plurality of scraper rings are fixedly mounted on the outer wall of the connecting rod. The scraper rings can be used to scrape off the lubricating oil adhering to the inner wall of the oil pan body, thereby accelerating the release of the lubricating oil.

[0016] 2. The oil pan capable of rapid oil draining, when the lubricating oil inside the oil pan body is drained, the tapered block is pushed and pulled back and forth, and at the same time, in conjunction with the sliding tube, limit block, connecting rod, and scraper ring, the lubricating oil adhered to the inner wall of the oil pan body can be scraped off, so that the lubricating oil inside the oil pan body can be fully discharged, thereby further increasing the lubricating oil draining speed and improving the oil draining quality of the oil pan body.

[0024] like Figures 1-6 As shown, the utility model provides a technical solution: an oil pan that can quickly drain oil, including an oil pan body 1, a drain hole 2 is opened at the bottom of the oil pan body 1, and an oil drain plug 3 is threadedly connected to the inner wall of the oil drain hole 2. When the lubricating oil inside the oil pan body 1 needs to be drained, the drain plug 3 is rotated to disengage from the oil drain hole 2 and separate from the oil pan body 1. At this time, the lubricating oil inside the oil pan body 1 can be discharged through the oil drain hole 2. A ventilation mechanism 4 is provided inside the oil pan body 1 to increase the oil draining speed. By providing the ventilation mechanism 4, the internal air pressure of the oil pan body 1 can be balanced with the external atmospheric pressure, which can effectively avoid the occurrence of air intake when the oil drain hole 2 is draining oil, so that the lubricating oil can flow out smoothly and quickly. A cleaning mechanism 5 is provided inside the oil pan body 1 to improve the oil draining quality. By providing the cleaning mechanism 5, the lubricating oil attached to the inner wall of the oil pan body 1 can be scraped off, thereby accelerating the discharge of the lubricating oil.

[0025] The above-mentioned ventilation mechanism 4 includes a bracket 41, a spring 42, a conical block 43, a ventilation pipe 44, a sliding pipe 45, and a limit block 46; the bracket 41 is fixedly installed on the inner wall of the oil pan body 1, and the inner wall of the bracket 41 is fixedly installed with a ventilation pipe 44, and the ventilation pipe 44 passes through the bracket 41, and the inner wall of the ventilation pipe 44 is slidably connected with a sliding pipe 45, and the bottom of the sliding pipe 45 is attached to the top of the oil drain plug 3, and the sliding pipe 45 and the oil drain hole 2 are in a concentric state. External air can be introduced into the interior of the oil pan body 1 through the sliding pipe 45 and the ventilation pipe 44, so that the internal air pressure of the oil pan body 1 is balanced with the external atmospheric pressure, which can effectively avoid the air intake phenomenon when the oil drain hole 2 is draining oil, so that the lubricating oil can flow out smoothly and quickly through the oil drain hole 2. A limit block 46 is fixedly installed on the outer wall of the tube 45, and a spring 42 is sleeved on the outer wall of the sliding tube 45. One end of the spring 42 is fixedly installed on the bottom of the bracket 41, and the other end of the spring 42 is fixedly installed on the top of the limit block 46. The tapered block 43 is fixedly installed on the bottom of the sliding tube 45. When the oil drain plug 3 is separated from the oil drain hole 2, the elasticity of the spring 42 and the limit block 46 can push the sliding tube 45 downward, and the sliding tube 45 drives the tapered block 43 to slide out of the oil pan body 1 through the oil drain hole 2. At this time, the lubricating oil released from the oil drain hole 2 can be guided to the four sides of the sliding tube 45 through the tapered block 43 to prevent the lubricating oil from blocking the bottom of the sliding tube 45, so that the sliding tube 45 can remain hollow, which is beneficial to the air circulation inside and outside the oil pan body 1.

[0026] The above-mentioned cleaning mechanism 5 includes a connecting rod 51 and a scraper ring 52; the connecting rod 51 is fixedly installed on the side wall of the limit block 46, and multiple groups of scraper rings 52 are fixedly installed on the outer wall of the connecting rod 51. The outer wall of the scraper ring 52 is in contact with the inner wall of the oil pan body 1. The scraper ring 52 can be moved up and down reciprocatingly to scrape off the lubricating oil attached to the inner wall of the oil pan body 1, so that the lubricating oil inside the oil pan body 1 can be fully discharged, thereby further improving the lubricating oil discharge speed. When the lubricating oil inside the oil pan body 1 is discharged, the conical block 43 is pushed and pulled back and forth, and at the same time, in conjunction with the sliding tube 45, the limit block 46, and the connecting rod 51, the multiple groups of scraper rings 52 can be driven to move back and forth up and down in contact with the inner wall of the oil pan body 1.

[0027] Working principle: When the lubricating oil inside the oil pan body 1 needs to be released, the oil drain plug 3 is rotated to disengage it from the oil drain hole 2 and separate it from the oil pan body 1. At this time, the lubricating oil inside the oil pan body 1 can be discharged through the oil drain hole 2. When the oil drain plug 3 is separated from the oil drain hole 2, the sliding tube 45 can be pushed downward by the elastic cooperation of the spring 42 and the limit block 46, and the sliding tube 45 drives the conical block 43 to slide out of the oil pan body 1 through the oil drain hole 2. At this time, external air can be introduced into the interior of the oil pan body 1 through the sliding tube 45 and the ventilation pipe 44, so that the internal air pressure of the oil pan body 1 is balanced with the external atmospheric pressure, which can effectively avoid the air intake phenomenon when the oil drain hole 2 is draining, so that the lubricating oil can flow out smoothly and quickly through the oil drain hole 2, thereby improving the oil draining efficiency of the oil pan body 1.

[0028] When the lubricating oil inside the oil pan body 1 is drained, the conical block 43 is pushed and pulled back and forth, thereby driving the sliding tube 45 to slide back and forth on the inner wall of the vent pipe 44. At the same time, the sliding tube 45 will drive the limit block 46 to move back and forth synchronously. At the same time, the connecting rod 51 can drive multiple groups of scraper rings 52 to fit the inner wall of the oil pan body 1 and move back and forth. The up and down reciprocating movement of the scraper rings 52 can scrape off the lubricating oil attached to the inner wall of the oil pan body 1, so that the lubricating oil inside the oil pan body 1 can be fully discharged, thereby further improving the lubricating oil draining speed and improving the oil draining quality of the oil pan body 1.

[0029] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
