The structure can effectively strengthen the anti-damage capability of the fuel tank cover.
And the lower end of the protective pipe body is welded with the disc bottom, so that the oil pumping pipe is difficult to penetrate into the oil tank to steal oil even if the oil filter screen is damaged. Therefore, the oil-theft-proof device has better oil-theft-proof function.
Drawings
Fig. 1 is a schematic structural view of an embodiment of the present utility model.
Fig. 2 is a schematic top view of a tray bottom and oil screen support in an embodiment of the utility model.
In the figure: 1. the oil tank cover comprises an oil tank cover body, an internal thread, an air vent, an anti-skid knurl, a pipe body, an oil hole passing through the pipe wall, an oil filter screen, an oil pan bottom, an oil hole passing through the oil pan bottom, an oil filter screen bracket and an oil filter screen bracket.
Description of the embodiments
The utility model is further described below with reference to examples and figures.
As shown in fig. 1 and 2, an embodiment of a truck oil tank protecting device in a mine pit comprises a pipe body 2 with an open upper end and a welded lower end with a pan bottom 4. Also included is a fuel cap 1 with internal threads 1 a.
The pipe body 2 comprises a connecting section, an external thread section and an oil passing section, wherein the outer wall of the connecting section is used for being welded at the oil filling opening of the oil tank, the external thread section is integrated with the connecting section and is positioned on the upper side of the connecting section, and the oil passing section is integrated with the connecting section and is positioned on the lower side of the connecting section. Wherein, the open end of the pipe body 2 is connected with the fuel tank cap 1 in a mode of matching the internal thread 1a and the external thread section. The disc bottom 4 is provided with a plurality of disc bottom oil passing holes 4a in the form of through holes, and the wall of the oil passing section is provided with a plurality of tube wall oil passing holes 2a in the form of through holes.
Another embodiment further comprises an oil filter screen 3 with a mesh structure at the upper end opening and at the side and bottom. The oil filter screen 3 is arranged inside the oil passing section of the pipe body 2, the side edge of the oil filter screen 3 is leaned against the inner wall of the oil passing section of the pipe body 2, and the bottom side of the oil filter screen 3 is leaned against the upper side surface of the disc bottom 4.
Although the oil filter screen 3 has a self-positioning function in the pipe body 2, in order to position the oil filter screen 3 more firmly, in another embodiment, an oil filter screen holder 4b is added. The oil filter screen holder 4b is a circular ring-shaped pressing ring having an outer diameter slightly smaller than the disc bottom 4, which is mounted on the bottom upper side of the oil filter screen 3, the periphery thereof being for pressing the side edge of the oil filter screen 3, and the lower side thereof being for pressing the periphery of the bottom side of the oil filter screen 3.
The outer wall of the fuel tank cap 1 is provided with anti-skid knurls 1c along the circumferential direction, and the anti-skid function is achieved in the screwing process.
