[0001] The utility model relates to the technical field of hydraulic filtration, in particular to a hydraulic oil return filter element. Background Art

[0002] In the prior art, existing engineering machinery vehicles are usually equipped with relevant hydraulic oil return filter elements for hydraulic filtration, and most of the common hydraulic oil return filter elements are integral. After long-term use, if there is a lot of residue retained on the hydraulic oil return filter element, it is very easy to cause poor filtering effect of the hydraulic oil return filter element. Since most of the common hydraulic oil return filter elements are integral and it is more troublesome to disassemble, it is more troublesome to operate during cleaning, and even due to structural reasons, it is easy to have poor cleaning effect during cleaning, resulting in residues still retained inside the hydraulic oil return filter element, affecting the filtration of the hydraulic oil return filter element, resulting in the hydraulic oil return filter element not having good and convenient disassembly and cleaning measures, which seriously affects the filtration efficiency of the hydraulic oil return filter element. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art. Most of the common hydraulic oil return filter elements are integral.

Since disassembly is troublesome, it is very easy to have a poor cleaning effect, which seriously affects the filtering efficiency of the hydraulic oil return filter element. A hydraulic oil return filter element is provided.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a hydraulic oil return filter element, comprising: a base, an outer filter element is arranged on one side of the base, a fixing mechanism is arranged on one side of the outer filter element, a top seat is arranged on one side of the outer filter element, an inner filter element is arranged inside the outer filter element, the fixing mechanism comprises a fixing sleeve arranged on the outer surface of the top seat, a fixing rod is fixedly connected to one side of the base, a fixing block is arranged on one side of the top seat, a pop-up mechanism is arranged on one side of the top seat, and a threaded ring is arranged on the inner wall of the fixing sleeve.

[0005] As a preferred embodiment, a fixing hole matched with the fixing rod is formed on one side of the top seat, and a fixing groove matched with the fixing block is formed on one side of the fixing rod.

[0006] As a preferred embodiment, the outer surface of the top seat is provided with a thread groove matching the thread on the thread ring.

[0007] As a preferred embodiment, the pop-up mechanism includes a connecting rod slidingly passing through one side of the top seat, a spring is sleeved on the outer surface of the connecting rod, and one end of the connecting rod is fixedly connected to a limiting disk.

[0008] As a preferred implementation, one end of the connecting rod is fixedly connected to one side of the fixing block, and a limiting groove matched with the limiting plate is provided inside the top seat.

[0009] As a preferred implementation, one end of the spring is welded to one side of the inner wall of the limiting groove inside the top seat, and the other end of the spring is welded to one side of the limiting plate.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] The utility model provides a fixing mechanism and a spring-opening mechanism, and the fixing sleeve is rotated to separate from the top seat. The fixing block is fixed by means of the thread between the fixing sleeve and the top seat, so that the fixing rod is kept well and stably fixed, and the probability of separation between the fixing rod and the top seat is reduced. When the fixing sleeve is separated from the top seat, the fixing block is actively moved out from the fixing groove of the fixing rod by means of the elastic force of the spring, the limit plate and the connecting rod, so that the top seat and the fixing rod are no longer fixed, and the top seat is dragged to separate from the outer filter element and the inner filter element, and the outer filter element is removed for cleaning, so that the outer filter element and the inner filter element have good and convenient operation and disassembly measures, and the outer filter element and the inner filter element after disassembly are cleaned, thereby reducing the probability of poor cleaning effect of the outer filter element and the inner filter element during the cleaning process, improving the cleaning effect of the outer filter element and the inner filter element, reducing the probability of poor filtering effect of the device due to poor cleaning, and improving the filtering efficiency of the device.

When the fixing sleeve 31 is separated from the top seat 4, the spring 352 is no longer affected by the force and its shape gradually recovers, and in the process of shape recovery, it drives the limit plate 353 to actively move, and the limit plate 353 moves inside the top seat 4 and moves. During the movement, the connecting rod 351 is driven to move, and the connecting rod 351 gradually moves out from the inside of the top seat 4, and during the movement, the fixing block 33 is driven to move, and the fixing block 33 actively disengages from the fixing rod 32 until the fixing block 33 moves out from the inside of the fixing groove 36 on the fixing rod 32, dragging the top seat 4 to move, and the fixing rod 32 gradually disengages from the top seat 4 until the top seat 4 is completely removed. After the top seat 4 is removed, the outer filter element 2 is dragged to separate from the base 1, and after the outer filter element 2 is separated, the outer filter element 2 and the inner filter element 5 can be cleaned.
