[0031] In order to make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the specific embodiments of the present utility model. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this patent.
[0032] In a typical implementation manner of the present utility model, as Figures 1-6 shown, an anti-theft oil component for a heavy truck is proposed, including: an oil level sensor protection cover 1, a fuel tank cap protection cover 2, and an oil drain port protection cover 3. The oil level sensor protection cover 1 is used to be installed outside the oil level sensor to cover and protect the oil level sensor. The fuel tank cap protection cover 2 is used to be installed outside the fuel tank cap 9 to cover and protect the fuel tank cap 9. The oil drain port protection cover 3 is used to be installed outside the oil drain port to cover and protect the oil drain port. Through the combined cooperation of the oil level sensor protection cover 1, the fuel tank cap protection cover 2, and the oil drain port protection cover 3, the fuel tank 4 is comprehensively protected, playing a role in preventing oil theft.
[0033] As Figure 1 、 Figure 2 shown, the oil level sensor protection cover 1 is of a rectangular cover structure. One side of the oil level sensor protection cover 1 is provided with an opening for the installation of the oil pipe. Two first limit plates 10 are respectively welded and fixedly connected to both ends of the oil level sensor protection cover 1. The first limit plates 10 are of a metal plate structure and are used to limit the position of the oil level sensor protection cover 1 to prevent the oil level sensor protection cover 1 from being pulled out.
[0034] As Figure 1 shown, the fuel tank 4 of the truck is installed on the fuel tank bracket 6 and is tightly fixed to the fuel tank bracket 6 by the fixing belt 5. In practical applications, the first limit plates 10 are used to be placed below the fixing belt 5 to be pressed by the fixing belt 5, so as to realize the installation limit of the oil level sensor protection cover 1. One end of the first limit plate 10 away from the oil level sensor protection cover 1 is provided with an upward flanging to limit the lateral movement of the oil level sensor protection cover 1 through the cooperation of the flanging and the fixing belt 5, avoiding damaging the oil level sensor. In order to avoid abrasion of the fuel tank 4, a rubber pad 11 is fixedly pasted at the bottom of the first limit plate 10.
[0035] The oil level sensor protective cover 1 is fixed and limited by the fixing strap 5 of the fuel tank 4. It does not need to be welded to the fuel tank 4 and can be assembled by the vehicle manufacturer at the factory or installed after-sales, which is convenient for use, avoids the improvement of the fuel tank structure, does not require the addition of fuel tank types, and reduces the R & D and production costs. Since special tools are required for the disassembly and assembly of the fixing strap 5, it is difficult for transportation personnel to disassemble it, and the fixing strap 5 cannot be forcibly damaged (the fleet manager needs to check), effectively preventing the occurrence of theft by transportation personnel.
[0036] The fuel tank cap protective cover 2 is used for detachably installing on the fuel filling port of the fuel tank 4 and covering the fuel tank cap 9. As Figures 3-4 shown, the fuel tank cap protective cover 2 includes an upper cover 7 and an annular seat 8. One side of the upper cover 7 is fixedly provided with an L-shaped insertion plate, and the other side of the upper cover 7 is fixedly provided with an ear plate 15; one side of the annular seat 8 is fixedly provided with a connecting plate, and a through hole is opened on the connecting plate to allow the insertion of the insertion plate. The other side of the annular seat 8 is fixedly provided with an ear plate 15, and the ear plate 15 is arranged opposite to the insertion plate. The upper cover 7 is connected to the annular seat 8 through the insertion plate. The upper cover 7 and the annular seat 8 are also connected by a lock, and the lock is used to connect the two ear plates 15 on the upper cover 7 and the annular seat 8.
[0037] Among them, the annular seat 8 is of an annular plate structure. The outer diameter of the annular seat 8 is larger than the outer diameter of the fuel tank cap 9, and the inner diameter of the annular seat 8 is adapted to the fuel filling port of the fuel tank 4 and smaller than the outer diameter of the fuel tank cap 9, so that the annular seat 8 can be sleeved on the fuel filling port of the fuel tank 4 and be pressed and limited by the fuel tank cap 9. A rubber pad 11 is fixedly provided on the inner wall of the annular seat 8 to achieve an interference fit with the fuel filling port through the rubber pad 11, avoiding the axial sliding of the fuel tank cap protective cover 2 on the fuel filling port;
[0038] The upper cover 7 is used to buckle on the fuel tank cap 9. The inside of the upper cover 7 has a space for accommodating the fuel tank cap 9, and the fuel tank cap 9 and the upper cover 7 can rotate relative to each other, that is, when the upper cover 7 is twisted, the fuel tank cap 9 cannot be driven to rotate. Thus, the cooperation between the upper cover 7 and the annular seat 8 can be used to achieve the covering and protection of the fuel tank cap 9. The fuel tank cap protective cover 2 does not need to be welded to the fuel tank 4 and can be assembled by the vehicle manufacturer at the factory or installed after-sales, which is convenient for use, avoids the improvement of the fuel tank structure, does not require the addition of fuel tank types, and reduces the R & D and production costs. And the key of the lock can be controlled by the fleet manager, effectively preventing the occurrence of theft by transportation personnel.
[0039] In order to avoid wear between the upper cover 7 and the fuel tank cap 9 during installation, a rubber pad 11 is fixedly pasted on the inner wall of the upper cover 7 to ensure the service life of the fuel tank cap 9.
[0040] The drain port protective cover 3 is used for detachably installing at the drain port at the bottom of the fuel tank 4. As Figures 5-6As shown, the oil drain port protective cover 3 includes two arc-shaped cover bodies 12. One side of the two cover bodies 12 is hinged through a rotating shaft. On the other side of the two cover bodies 12, an ear plate 15 is fixedly provided respectively, and the two ear plates 15 are connected through a lock to lock the positions of the two cover bodies 12.
[0041] A baffle 13 is fixedly provided at the bottom of the cover body 12 (the end far from the oil drain port of the fuel tank 4) to block the oil drain port. A second limiting plate 14 is also fixedly provided on the inner wall of the cover body 12. The second limiting plate 14 is an arc-shaped plate and is used to be clamped in the gap between the oil drain port of the fuel tank and the drain bolt, so as to install the oil drain port protective cover 3 at the oil drain port to protect the drain bolt and prevent the drain bolt from being unscrewed.
[0042] Since there is a sealing washer between the oil drain port of the fuel tank and the drain bolt, there is a gap between the oil drain port of the fuel tank and the drain bolt to facilitate the clamping of the second limiting plate 14. The drain bolt can be placed in the space between the second limiting plate 14 and the baffle 13. The space on the side of the second limiting plate 14 away from the baffle 13 accommodates the end of the oil drain port and the sealing washer, so as to realize the overall protection of the oil drain port. The oil drain port protective cover 3 does not need to be welded and fixed to the fuel tank 4. It can be assembled by the vehicle manufacturer at the time of factory production or can also be installed after-sales, which is convenient for use, avoids the improvement of the fuel tank structure, does not need to increase the types of fuel tanks, reduces the R & D and production costs, and the key can be controlled by the fleet manager, effectively preventing the occurrence of the phenomenon of transportation personnel stealing on their own.
[0043] It should be noted that the space between the baffle 13 and the second limiting plate 14 is larger than the drain bolt, so that the drain bolt and the oil drain port protective cover 3 can rotate relative to each other to avoid driving the drain bolt to rotate when the oil drain port protective cover 3 is screwed, and prevent the drain bolt from being removed.
[0044] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
