Description

Technical Field

[0001] The utility model belongs to the technical field of oil pans, and in particular relates to a high-strength combined oil pan structure. Background Art

[0002] The oil pan refers to the lower half of the crankcase, also known as the lower crankcase.

This technology discloses "the main body of the oil pan, the front axle connecting plate and the oil filling structure; the oil pan structure is mainly used in large tractors and other models with complex application conditions and high structural strength requirements; the front end of the oil pan is a structural part directly connected to the front axle of the whole vehicle, and the load-bearing requirements are relatively high, requiring the oil pan to have high structural strength; in order to adapt to the front axle structure of the whole vehicle with different connection sizes, the oil pan structure is decomposed into the main structure of the oil pan and the front axle connecting plate. The front axle connecting plate is also a load-bearing structure with high structural strength. At the same time, while ensuring the structural strength, the weight is reduced as much as possible to reduce the overall weight of the oil pan. This structure can be applied to different models and the assembly requirements of different front axles, and can better adapt to the market."

[0004] Although the design has high structural strength, while ensuring structural strength, the weight is reduced as much as possible to reduce the overall weight of the oil pan.

[0044] In this embodiment: the hole opened on the surface of the bolt 9 can form a stable connection between it and the latch tooth 8, so that the bolt 9 can be prevented from loosening under the stability of the latch tooth 8 and the support bar 7, and the connection between the oil pan body 2 and the mounting plate 1 can be made more stable.

[0045] The working principle and use process of the utility model are as follows: when installing the oil pan body 2, the mounting plate 1 and the oil pan body 2 can be connected by the bolt 9, at this time, the slide bar 6 and the support bar 7 can be pulled, and the slide bar 6 will compress the spring 5 located inside the slide hole 3 through the positioning plate 4 at its top, and then the slide bar 6 can be rotated, and the support bar 7 and the latching tooth 8 will move to the bottom of the bolt 9 under the drive of the slide bar 6, and then the slide bar 6 can be loosened, and the latching tooth 8 will be inserted into the groove provided on the surface of the bolt 9 under the rebound of the spring 5, and the angle of the bolt 9 is fixed. When the bolt 9 needs to be removed, the slide bar 6 can be pulled again and rotated, so that there is space for the bolt 9 to be removed.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
