[0020] The following is combined with Figure 1-4 The specific implementation modes of the present utility model are further described in detail.

[0021] like Figure 1-4 The figure shows a preferred embodiment of the hydraulic oil filter element of the utility model which is easy to disassemble and separate, including a filter element main body 10, which is installed in a filter cartridge 20, and the upper end of the filter element main body 10 is fixed with an end cover 30 by pressing, and the inner wall of the upper end of the filter cartridge 20 is provided with an integrally formed support portion 40, and the end cover 30 and the support portion 40 are threadedly connected to fix the filter element main body 10 in the filter cartridge 20, specifically, the surface of the support portion 40 is integrally formed with an external thread 41, and the inner side of the lower end of the end cover 30 is threadedly connected with the external thread 41. When in use, hydraulic oil enters the filter element main body 10 through the oil inlet on the end cover 30, and the filtered hydraulic oil flows into the filter cartridge 20. The above is an existing hydraulic oil filter element and its installation structure, which will not be described here.

[0022] In this embodiment, a handle 50 is provided on the end cover 30. The handle 50 facilitates grabbing the end cover 30 and rotating the filter element body 10, thereby facilitating disassembly of the filter element body 10.

[0023] In addition, in the prior art, the end cover 30 and the support portion 40 are connected by a thread but do not have a limiting structure. This makes it easy for the end cover 30 to tilt in the horizontal direction and cause thread slippage when the end cover 30 is manually rotated. In order to avoid the problem of thread slippage, the hydraulic oil filter element that is easy to disassemble and separate in the utility model is provided with a guide assembly 60 between the end cover 30 and the support portion 40. Through the setting of the guide assembly 60, the end cover 30 remains horizontal during the rotation process, thereby avoiding the problem of thread slippage.

[0024] A specific embodiment of the guide assembly 60 is as follows:

[0025] The guide assembly 60 includes a guide connecting ring 61 rotatably mounted on the outside of the end cover 30 and a limiting structure 62 arranged between the support portion 40 and the guide connecting ring 61 for guiding the guide connecting ring 61 in the vertical direction. When the end cover 30 rotates, it can drive the guide connecting ring 61 to move in the vertical direction. The setting of the limiting structure 62 can guide the guide connecting ring 61 so that the guide connecting ring 61 maintains a horizontal rise during the movement, thereby allowing the end cover 30 to maintain a horizontal state during the rotation to prevent thread slippage.

[0026] Specifically, a rotation groove 63 is embedded in the inner wall of the guide connection ring 61 , and the side surface of the end cover 30 is rotatably disposed in the rotation groove 63 .

[0027] The limiting structure 62 includes a guide nose 621 fixed on the side of the guide connecting ring 61 and a guide rod 622 fixed on the support part 40. The guide nose 621 is slidably connected to the guide rod 622. Through the setting of the guide nose 621 and the guide rod 622, the guide connecting ring 61 remains horizontal when moving in the vertical direction.

[0028] The handle 50 is a hole-shaped handle structure. There are at least two handle structures, and the handle structures are evenly distributed around the center of the end cover 30 .

[0029] Please refer to Figure 1-3 In the present embodiment, the handle 50 is rotatably mounted on the surface of the end cover 30. When rotating the end cover 30, the two handles 50 can be held by both hands to rotate the end cover 30, which is convenient for applying force.

[0030] like Figure 4 The second embodiment of the hydraulic oil filter element handle 50 of the present invention is shown. In this embodiment, the handle 50 is fixed on the surface of the end cover 30.

[0031] The utility model is convenient for disassembling and separating the hydraulic oil filter element. When disassembling, the hydraulic oil filter element can be disassembled by holding the handle 50

[0032] The filter element body 10 can be disassembled by rotating the end cover 30 to separate the threads of the end cover 30 and the support portion 40. During the rotation of the end cover 30, the end cover 30 is guided and limited by the guide assembly 60, so that the end cover 30 remains horizontal during the rotation, which effectively solves the problem of thread slippage of the end cover 30 during the rotation in the prior art.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
