The existing oil storage tank is generally blow-molded and can be a rectangular parallelepiped, a cube or other special-shaped structures. An oil drain port needs to be opened on the top for oil to pass through. The common blow-molded oil storage tank has a large opening of the top surface oil drain port, which can easily cause the front side of the oil storage tank to deform and sag inward. In actual applications, the oil drain component is often stuck, affecting the normal process flow. Utility Model Content

[0011] Preferably, the oil tank body is provided with a mounting opening through which the oil pump bracket and the oil pump can pass.

[0012] Preferably, the cover plate is fixedly connected to the oil tank body by screws.

[0013] A fuel injection nozzle cleaning detector comprises a housing, wherein the above-mentioned anti-deformation oil tank is arranged inside the housing.

[0014] In the anti-deformation oil tank disclosed by the utility model, the oil tank body can be formed by a blow molding process, and the cover plate can be a hardware cover plate. After the oil pump bracket is fixed to the bottom of the cover plate, the cover plate is covered on the top surface of the oil tank body and fixed by screws or the like, and it is ensured that the cover plate opening is aligned with the oil drain port up and down.

[0021] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0022] The utility model discloses an anti-deformation oil tank, combined with Figures 1 to 4As shown, it includes a fuel tank body 1, a fuel pump bracket 2 and a cover plate 3, the cover plate 3 is fitted and fixed to the top surface of the fuel tank body 1, the fuel pump bracket 2 is arranged in the fuel tank body 1, and the upper end of the fuel pump bracket 2 is fixedly connected to the cover plate 3, an fuel pump 4 is fixed on the fuel pump bracket 2, an oil discharge port 10 is opened on the top surface of the fuel tank body 1, a cover plate opening 30 is provided on the cover plate 3, the cover plate opening 30 is aligned with the oil discharge port 10, and the edge of the cover plate opening 30 is clamped and matched with the edge of the oil discharge port 10.

[0023] In the above structure, the fuel tank body 1 can be formed by blow molding, and the cover plate 3 can be a cover plate with a certain mechanical strength, such as a hardware cover plate. After the oil pump bracket 2 is fixed to the bottom of the cover plate 3, the cover plate 3 is covered on the top surface of the fuel tank body 1 and fixed by screws or the like, and it is ensured that the cover plate opening 30 is aligned with the oil drain port 10 up and down. On this basis, the utility model makes the edge of the cover plate opening 30 and the edge of the oil drain port 10 clamped and matched, and the clamping matching method includes abutment, edging, etc. Under the fitting reinforcement effect of the cover plate 3 and the clamping effect of the edge of the cover plate opening 30 and the oil drain port 10, the overall mechanical strength of the fuel tank is greatly improved, and the occurrence of fuel tank dent deformation and the like is better avoided. In addition, compared with the method of directly fixing the oil pump to the fuel tank body 1, the utility model uses the cover plate 3 to support and fix the oil pump, so that the installation of the oil pump is more stable and reliable, thereby improving the overall performance of the fuel tank.

[0024] As a preferred embodiment, the cover plate opening 30 and the oil drain port 10 are both rectangular openings. On this basis, the four edges of the cover plate opening 30 are respectively formed with downwardly bent inner edges 31 , and the inner edges 31 are in abutment with the edges of the oil drain port 10 .

[0025] In the above structure, this embodiment preferably adopts a method of tightly abutting the inner edge 31 against the edge of the oil discharge port 10 to achieve a clamping fit. This fitting method is convenient for installation and can effectively prevent the oil discharge port 10 from being sunken and deformed.

[0026] See also Figure 3 and Figure 4 In this embodiment, the inner edge 31 is a trapezoidal inner edge. In the actual processing, taking the cover plate 3 as a hardware part, it is only necessary to cut a certain depth at the four corners of the cover plate opening 30, and then bend the four edges downward to obtain a trapezoidal inner edge, and the processing process is simple and convenient.

[0028] Furthermore, the two upper ends of the oil pump bracket 2 are formed with outwardly bent ears 20, and the ears 20 are fixedly connected to the cover plate 3 by screws. Among them, because the ears 20 are bent outward, they can fit the cover plate 3 well, and then the two are fixed by screws.

[0029] For ease of installation, in this embodiment, see Figure 2 The oil tank body 1 is provided with a mounting opening 11 through which the oil pump bracket 2 and the oil pump 4 can pass.

[0030] See also Figure 2 In this embodiment, the cover plate 3 and the fuel tank body 1 are fixedly connected by screws.
