[0024] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0025] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0026] Example 1, as Figures 1-6 shown, the present utility model provides an oil filter for hydraulic lubricating oil, including a filtration tank 1. A discharge port 3 is arranged at the bottom of the filtration tank 1. A feed port 2 is connected to the top of one side of the filtration tank 1. A disassembly component 4 is arranged inside the filtration tank 1. The disassembly component 4 includes a notch 401 which is opened inside the filtration tank 1. Grooves 402 are opened on both inner walls of the notch 401. A filter screen 403 is arranged inside the notch 401. First slot holes 404 are opened at the front ends of both sides of the filter screen 403. A first spring 405 is arranged inside the first slot holes 404. A first push plate 406 is connected to one side of the first spring 405. An insertion block 407 is connected to one side of the first push plate 406. A push handle 408 is connected to the front surface of the first push plate 406. Second slot holes 409 are opened at the rear ends of both sides of the filter screen 403. A second spring 410 is arranged inside the second slot holes 409. A second push plate 411 is connected to one side of the second spring 410. A top block 412 is connected to one side of the second push plate 411. The outer surfaces of both sides of the filter screen 403 are attached to the inner walls of both sides of the notch 401. A sliding connection is formed between the filter screen 403 and the notch 401. An elastic structure is formed between the first push plate 406 and the first spring 405 through the first slot holes 404. An inclined opening is arranged on one side of the insertion block 407. The position and size of the insertion block 407 match the position and size of the groove 402. An elastic structure is formed between the second push plate 411 and the second spring 410 through the second slot holes 409.

[0027] The effect achieved by the entire Embodiment 1 is that when the lubricating oil is filtered for a long time, more impurities will adhere to the surface of the filter screen 403. When it is necessary to disassemble and clean the filter screen 403, two push handles 408 can be simultaneously pushed inward, so that the push handles 408 can drive the first push plate 406 to squeeze the first spring 405, and drive the insertion block 407 to be pulled out from the groove 402. After the insertion block 407 is completely pulled out from the groove 402, the second spring 410 will push the second push plate 411 through its own elastic force to push the filter screen 403 out of the notch 401 through the top block 412, thus completing the rapid disassembly of the filter screen 403. Then, the filter screen 403 can be cleaned. When it is necessary to install the filter screen 403, the filter screen 403 can be directly inserted into the notch 401. When the insertion block 407 contacts the inner wall of the notch 401, continue to push the filter screen 403, so that the insertion block 407 can be squeezed by the notch 401, and then the insertion block 407 pushes the first push plate 406 to squeeze the first spring 405. At this time, the insertion block 407 will also shrink into the first spring 405. At the same time, the top block 412 will also push the second push plate 411 to squeeze the second spring 410. After the filter screen 403 is completely inserted into the notch 401, the first spring 405 will push the first push plate 406 through its own elasticity to drive the insertion block 407 to insert into the groove 402 to complete the fixation, avoiding the problem that the existing filter screen 403 is not convenient to disassemble and improving the convenience of disassembling the filter screen 403.

[0028] Embodiment 2 is as Figure 1 、 Figure 2 and Figure 7 shown. A stirring assembly 5 is arranged at the central position of the top of the filter tank 1. The stirring assembly 5 includes a motor 501. The output end of the motor 501 is connected with a stirring rod 502. Scraping plates 503 are arranged on both sides of the stirring rod 502. The motor 501 is electrically connected to an external power supply through a control switch. The output end of the motor 501 penetrates through the filter tank 1 and is fixedly connected with the stirring rod 502. The outer surface of the scraping plate 503 is attached to the inner wall of the filter tank 1.

[0029] The effect achieved by the entire Embodiment 2 is that when filtering the lubricating oil, the motor 501 can be first started through the control switch, so that the motor 501 can drive the stirring rod 502 to stir inside the filter tank 1 through the output end. Then, the lubricating oil to be filtered is poured into the filter tank 1 through the feed port 2, and the lubricating oil is stirred by the stirring rod 502, effectively improving the filtering speed. And during the stirring, it will drive the scraping plate 503 to clean the lubricating oil on the inner wall of the filter tank 1 to prevent the lubricating oil from adhering to the inner wall of the filter tank 1.

[0030] Working principle: When the filter screen 403 needs to be disassembled, the push handle 408 can be toggled inward so that the insertion block 407 can be withdrawn from the groove 402. Then, the second spring 410 will push the filter screen 403 out of the notch 401 through its own elastic force to complete the installation and disassembly. When installing the filter screen 403, the filter screen 403 can be directly inserted into the notch 401 for fixation, avoiding the problem that the existing filter screen 403 is not convenient enough to disassemble, improving the convenience of disassembling the filter screen 403. While filtering the lubricating oil, the motor 501 can be started to drive the stirring rod 502 in the filter tank 1 to stir the lubricating oil, further improving the filtering efficiency and the overall practicality.

[0031] The above is only the preferred embodiment of the present invention, and it does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
