Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] Please see Figure 1-3 As shown, this utility model is a novel simple anti-detachment device for an oil pump assembly, comprising:

[0023] The anti-detachment connection mechanism includes a connecting cover 11. A pump core fixing seat 13 is provided on one side of the lower part of the outer surface of the connecting cover 11. A constant pressure valve 12 is connected to the bottom end of the other side of the lower part of the outer surface of the connecting cover 11. A filter screen frame 14 is connected to the bottom end of the pump core fixing seat 13, and the upper end of the inner wall of the filter screen frame 14 is the connected filter screen.

[0024] The connecting cover 11 provides a structural installation environment, and the oil pump is installed and fixed with the help of the pump core fixing seat 13. The tight connection between itself and the connecting cover 11 ensures the stability of the oil pump structure. The filter screen frame 14 provides a filter screen installation environment and uses the filter screen to provide the oil filtration required.

[0025] The pump core mounting base 13 includes a mounting frame 131. The upper part of one side of the outer surface of the mounting frame 131 is symmetrically provided with protrusions. The inner sides of the closely adjacent protrusions abut against the protrusions on opposite sides of the outer surface of the constant pressure valve 12.

[0026] The mutual contact between the inner wall of the protrusion and the protrusion ensures the stability of the constant pressure valve 12 structure.

[0027] A fixing ring 132 is fixed to the upper part of the other side of the outer surface of the fixing bracket 131, and the inner wall of the fixing ring 132 fits into the upper part of the outer surface of the lower part of the cover.

[0028] The fitting between the retaining ring 132 and the outer surface of the connecting cover 11 ensures a tight connection between the two, thus ensuring the stability of the oil pump structure mounted on the pump core mounting base 13.

[0029] A first elastic block 134 is symmetrically provided on the lower part of the other side of the outer surface of the fixing frame 131, and the first elastic block 134 extends out into the groove opened below the lower outer surface of the upper cover 11.

[0030] The mutual contact between the first elastic locking block 134 and the groove can ensure secondary fixation between the pump core fixing seat 13 and the connecting cover 11.

[0031] A second elastic clip 135 is symmetrically fixed to the lower part of the other side of the outer surface of the fixing frame 131, and a clip 133 is provided at equal intervals at the upper end of the outer surface of the filter frame 14, with the second thermoelastic clip extending out of the upper part of the clip 133.

[0032] The mutual contact between the second elastic block 135 and the inner wall of the bracket 133 secures the filter frame 14 structurally.

[0033] The card holder 133 is in the shape of an oblique "L", and the top surface of the card holder 133 is provided with anti-slip textures at equal intervals;

[0034] The slanted "L" shape, combined with the anti-slip texture, allows for easy handling of the card holder 133, facilitating assembly and disassembly.

[0035] Working principle: The fixing ring 132 is used to fit the fixing frame 131 and the connecting cover 11 together. During the fitting process, the first elastic block 134 needs to be pressed beforehand so that it extends into the groove opened on the outer surface of the fixing frame 131. After the force is released, the first elastic block returns to its deformation and moves obliquely upward, and abuts against the inner wall of the groove. At the same time, during the fitting process, the inner wall of the closely adjacent protrusions on the fixing frame 131 abuts against the protrusion on the outer surface of the constant pressure valve 12, and fixes the structure. At this time, the connecting cover 11 and the pump core fixing seat 13 are in a tight connection state. Then, the end of the oil pump is attached to the plane position on one side of the outer surface of the pump core fixing seat 13, and the two are connected and installed by bolts. Then, the filter screen frame 14 structure is installed by the mutual abutment between the second elastic block 135 and the bracket 133.

[0036] This solution utilizes a simple connection between the top cover 11 and the pump core mounting base 13 to complete the installation and fixation of the oil pump structure. This simplifies the installation structure, requiring only the installation of fewer components during the installation process, thereby reducing the number of installation steps and the installation time. This reduces the probability of parts falling and being damaged during installation, saving costs and making it convenient to use. At the same time, it uses less material, further reducing costs, and adopts a snap-fit ​​connection method for easy assembly and disassembly.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
